introduction
With the development of social economy and science and technology, people have higher and higher requirements for living environment and quality of life. In addition to meeting basic living needs, it also needs to bring residents a sense of security and satisfaction, and assist government departments to do a good job in grassroots social governance. These pose new challenges to community management services. Deepening community security measures has become an important task in the construction of a social security prevention and control system. Smart community is a new concept of community management and a new mode of social management innovation under the new situation. The scope of the smart community has been continuously extended. The functions and services provided by the smart community are mainly reflected in the four modules of smart security, smart home, property management and community services. Among them, smart security is the most important part of protecting the safety of property owners. Through the construction of smart security communities, the transition from "traditional defense" to "technical defense" is realized, providing convenience for the people in the community, thereby helping the basic work of community security and promoting the construction of a harmonious community. As the main technical form of the smart security community, with the widespread coverage and deepening of the application of 4G networks, the gradual maturity and development of various IoT protocols and technologies, the technical display form of IoT + security has become the mainstream, and the effective processing of a large amount of real-time data generated by IoT devices has also become the main driving force for the growth of the integrated smart community market such as artificial intelligence + IoT. Issues such as data islands, data chimneys, and fragmented applications continue to emerge in the application of single-product intelligence, even multi-product intelligence, and system intelligence. After the intervention of artificial intelligence, IoT soon had a connected brain, and a series of problems such as data islands were quickly resolved. Whether it is the real-time massive data generated by IoT devices, or the countless training and deep learning of big data in the development of artificial intelligence, data is the key. After the integration of AI and IoT, the Internet of Things provides artificial intelligence with the data stream required for its training and deep learning, which promotes the gradual development of artificial intelligence to "applied intelligence"; artificial intelligence analyzes and processes real-time data and historical data in the data stream, and speculates on the habits of end users, thereby making devices smarter and smarter. That is to say, regardless of the form in which data existed independently of each other before, after the integration of AI and IoT, the data islands between enterprises and equipment and between equipment and equipment are completely broken. Integrating AI technology and IoT technology in the form of fusion technology, a large amount of data is generated and collected through the Internet of Things and stored in the cloud and edge Edge, and then through big data analysis, and a higher form of artificial intelligence, so as to realize the digitalization of all things and the intelligent connection of all things. Under such a technical background, the Internet of Things + security has become the mainstream technology form in the implementation of smart communities.
The development and application status of Internet of things + security in the construction of smart communities
Since 2017, various relevant departments in my country have intensively introduced a number of policies to support the development of the Internet of Things industry. In January 2017, the Ministry of Industry and Information Technology released the "Thirteenth Five-Year Plan for the Internet of Things", which clarified the development goals of the "Thirteenth Five-Year Plan" for the Internet of Things industry. In June of the same year, the Ministry of Industry and Information Technology issued the "Notice on Comprehensively Promoting the Construction and Development of Mobile Internet of Things (NB-IoT)". During this period, my country's relevant policies for building smart cities and smart communities have also been introduced one after another, further accelerating the development process of my country's Internet of Things. Under the guidance of policies and the promotion of industry insiders, the industrial scale of my country's Internet of Things has continued to expand in recent years, and the growth rate has also become faster and faster. According to the statistics of the "2017-2018 China Internet of Things Development Annual Report", from 2013 to 2017, the industrial scale of my country's Internet of Things has grown from 489.65 billion yuan to 1.186 billion yuan, with a compound annual growth rate of 25%. As the industrial scale of the Internet of Things continues to expand, people in the industry are also actively promoting the Internet of Things to be put into practical applications. At present, the Internet of Things has accelerated integration with many fields in my country, and has effectively promoted the development of more industries to achieve new breakthroughs. Among them, the Internet of Things has gradually been verified on a large scale in the fields of transportation, logistics, environmental protection, medical care, security, and electric power. It is also setting off a new round of industrial transformation in the fields of smart cities, industrial Internet of Things, Internet of Vehicles, and smart homes. In the actual landing process, the Internet of Things plays an important role in the construction of smart communities. With the help of the technical advantages of the Internet of Things, community managers can use remote monitoring and other equipment to understand the entry and exit of vehicles and the flow of people in the community in a timely manner, so as to efficiently manage the entire community. The security system of the smart community is divided into two categories: the whole community security system and the home security system. The development trend of smart community security system has the following four aspects:
1. The main technologies of smart security include a new generation of information technology such as Internet of Things technology, "cloud" technology, and big data technology
Use new technology equipment to improve the intelligence level of the security system, such as using comprehensive intelligent analysis technology and information promotion means to proactively discover and prevent security incidents. Actively notify people through the security reminder service to realize information interaction between security subsystems in the community; upgrade the TV monitoring system to an intelligent monitoring system to increase the security and intelligence of the community; through real-time intelligent analysis technology, large-scale data storage technology and data analysis and mining technology, the collected information is linked together, the on-site environment is intelligently analyzed, and the analysis results are reported to the early warning center to ensure preventive measures.
2. Adopt a large integrated platform to realize resource integration and data sharing
The security system of the smart community adopts a large integrated platform to realize system integration data sharing and resource integration data sharing between various levels. To this end, it is necessary to further improve the construction of two aspects: on the one hand, set up a gateway in the security system in the category of smart home to realize data sharing and linkage between the various security subsystems in the household; on the other hand, build a "public information network management platform" in the community, so that the security subsystems of the whole community can realize information sharing and linkage.
3. The connection between the smart community and the city's information platform
As one of the foundations of the smart city security system, the community security system and security database provide district-level and city-level public security systems with access to community security databases and interfaces for invoking community security devices, providing analysis basis for higher-level public security systems to solve cases and strengthen urban security management. Therefore, in addition to connecting the smart home security system with the public information platform of the smart community through the gateway, the public information platform of the smart community also needs to be connected with the information management platform of the smart city.
Judging from the application status of the Internet of Things + security and smart communities:
1. The Internet of Things accelerates the construction of smart communities
Generally speaking, as the cell of a city, a community reflects the degree of development of a city to a certain extent. Therefore, it is necessary to intelligently transform traditional communities. At present, my country is vigorously advocating the construction of smart cities and improving the level of intelligent management of cities. To achieve this goal, smart communities obviously cannot be ignored. On the whole, smart communities involve smart homes, smart buildings, smart security and other fields, mainly including smart home systems, security systems and smart management systems. Connecting related devices with the help of the Internet of Things can effectively improve the relevant environment for community medical and health services, cultural services and other activities, improve the community's infrastructure, and provide more convenience to the lives of community residents. At the same time, after adopting the Internet of Things technology, the security level of the entire community has also been further improved.
- The Internet of Things has become the main technology enabling carrier for the construction of smart communities
When it comes to the technical carrier of smart communities, with the building intercom system, electronic patrol system, access control system, home anti-theft alarm system and many other contents; the property management system includes remote meter reading billing system, parking lot management system, IC card management system, fire protection system, electronic bulletin system and other community security solutions. Let’s look at how the Internet of Things (IoT) is the main technology empowerment carrier for smart community construction from several common security applications in smart community construction: In terms of the current community security field, video surveillance is still the main battlefield of AI + security, accounting for nearly 90% of the market value. And under the call of national policies such as Ping An China and Xueliang Project, the urban three-dimensional prevention and control monitoring system has gradually taken shape, and the urban security data has shown a trend of geometric multiple growth. The city-level security big data not only faces the pressure of massive data collection, transmission and storage, but also its real-time and accuracy in the analysis and feedback links are also affected a lot. Relying on the traditional security architecture and means alone, the role of video surveillance in the security industry can only stay in monitoring and retention of certificates, not prevention. That is to say, the current mass of urban security data still exists in a single form, and the urban three-dimensional prevention and control monitoring system lacking multi-dimensional data collision has not gone out of the data island, and thus cannot solve the problem of realizing security AI. However, with the help of the Internet of Things, the security industry not only solves the two major problems of analysis and feedback, but also analyzes and processes massive heterogeneous data through machine learning and deep learning, coupled with the help of edge computing, it is possible to realize the structured processing of video data by front-end cameras. Also based on machine vision, endowing the front-end camera with more agile observation capabilities, such as face recognition, license plate recognition, gesture recognition, 3D structured light technology, etc., which are widely popular in the industry, have injected new vitality into the current security industry. Perhaps from a macro perspective, it is precisely because of the help of the Internet of Things that the security industry can be intelligentized, and even the intelligent security industry can truly achieve "universal security for all living beings". In the process of empowering the Internet of Things and artificial intelligence, face recognition should be the core scenario application of the current security industry. Whether it is a front-end smart camera or the first smart door lock for a family, face recognition has become an indispensable part of smart security. Person recognition is a higher-level application of face recognition technology in the security industry. This technology is widely embedded in cameras deployed in cities to collect thousands of faces and identify and match faces to find suspicious persons and criminal suspects. It is widely used in Ancheng City, Xueliang Project, Smart City, Smart Transportation and other applications. In the deployment of urban security, the smart camera embedded with face recognition technology can transmit the facial feature data to the computer central database through the computer network at the same time as taking suspicious portraits. The Guangzhou Zhigan Community, built by Jiadu Technology, has benefited from the arrest and escape of 13 people. There are also facial recognition derivative products deployed in urban buildings, such as smart access control and smart door locks, which have penetrated into all places that require identity authentication and identification, and have been well applied in smart campuses, building intercoms, smart communities, and smart finance. In the current construction of smart communities, face recognition technology has become the standard configuration of multiple systems such as access control management, visitor systems, and video security systems.
The application of Internet of Things + security in the construction of smart communities is difficult
With the development of society and economy and the advent of the Internet + era, technologies such as artificial intelligence, Internet of Things, cloud computing, 4G/5G, and big data continue to mature. People's attention to community services is no longer limited to community security infrastructure, but more interest and attention are placed on communication with the outside world, quality of life, security and other intelligent construction. This requires traditional communities to adopt advanced technological means, focus on the city's own laws of operation, perception of social chronic diseases, and various appeals of the masses, comprehensively grasp the vital signs of urban operation, the status of urban operation, and when there are emergencies and abnormal situations, early warning and prediction perception, relevant alarm numbers are turned into instructions, and they are pushed to relevant departments for quick disposal. On the other hand, in order to effectively deal with prominent problems that affect social security and stability, how to innovate a three-dimensional social security prevention and control system and comprehensively improve the intelligent level of community governance through new technological means such as artificial intelligence, the Internet of Things, and big data, so as to realize full collection of community personnel and vehicle information, full control of activity tracks, full sharing of data and information, and full response to people's requests for help, etc., and strive to improve the sense of gain, happiness, and security of the masses is the top priority of the current smart community construction. However, based on the experience of building smart communities in various provinces across the country and the implementation of projects, from the perspective of technology, management, operation, and application, it is not difficult for us to analyze some challenges faced by the construction of smart communities:
1. Lack of standards and norms for smart community construction
Due to the incomplete top-level design and construction specifications of smart communities related to the country and industry, and the lack of specifications for engineering design, construction installation, and equipment selection, the construction of various places is relatively random. In addition, after the system is completed, there are no corresponding acceptance and testing standards, and there is no relevant department to organize acceptance. Therefore, there is an urgent need to issue such technical specifications for smart communities, so as to effectively regulate the implementation of related systems in smart communities.
2. Lack of means to manage the floating population
At present, there are a large number of floating population in cities, and the composition is complex, resulting in the change of floating population information not being recorded and entered in a timely manner, which brings great management difficulties to the management of floating population in the community. In addition, it is difficult to grasp the movement of floating population, which makes it difficult for the management department to implement control measures. Due to the weak awareness of the floating population, the self-consciousness of voluntarily reporting to the public security organs is not high. In order to pursue profits and tenants in order to save costs, some community landlords often do not apply for registration at the police station and community property, resulting in the number of people registered. With the increasing number of foreigners entering the city every year, the security risks and security cases brought about by it are gradually increasing, which poses a huge challenge to security prevention.
3. Lack of comprehensive community governance mechanism
With the rapid development of the economy, more and more communities are built and put into use. Due to the situation of self-occupation and lease in the original old community, the management of the old community has become increasingly complicated. Some communities have not been equipped with corresponding property management, and the personal and property safety of residents cannot be guaranteed. At present, the police force in each police station does not match the ratio of grid personnel. Relying on "manual methods" for visit collection, input, maintenance, and processing, grass-roots community management is under great pressure. There is a lack of perfect management process mechanism, and efficient management methods are urgently needed.
4. Lack of convenient, convenient and convenient measures
The rapid economic development has brought about an increase in people's requirements for the living environment, especially higher requirements for the quality of community construction. The current community is insufficiently intelligent, lacking public services such as community medical care, care and assistance, information policy release, vehicle management, and housing management. Residents' satisfaction is low, especially in old communities. At the same time, community management has attracted more and more attention to the monitoring of fire safety hazards and the care of widowed and elderly people.
V. Lack of Basic Data Governance and Management Applications
In the past, the construction of communities was done on their own, lacking unified planning and design, and there were situations such as repeated construction of some systems and repeated data entry. In addition, community-based collection data coverage is incomplete, collection methods are single, information databases are updated slowly and systems are independent of each other, information islands are serious, data is not unified and integrated, and there is a lack of in-depth data mining and analysis methods, resulting in extremely low data use value. Therefore, the real-time, accuracy, and effectiveness of data urgently need to be improved, and the tentacles of management and services will be extended to thousands of households through the multi-dimensional perception and collection of grassroots data.
From the perspective of security, communities can be divided into open communities and closed communities. Open communities mainly include urban villages, transformed communities, and mixed commercial and residential communities; closed communities mainly include property communities and unit courtyards. The security risks faced by different types of communities and the prevention problems that need to be solved are quite different, and the stakeholders that need to be linked are also different.
1. Urban villages, transformed communities (open communities)
Take urban villages in open communities and transformed communities as examples. Due to historical and economic reasons, there are usually many rental houses and short-term rental houses in the community, the registered population is small, and the migrant population accounts for the majority. The openness and complexity of urban villages and transformed communities make their security precautions far more difficult than closed property communities. In terms of technology, due to the difficulty of effectively managing the entry and exit of people and vehicles, the security technologies commonly used in smart community construction, such as video surveillance, intrusion alarm, parking lot management, and access control management, play an extremely limited role. Smarter technical means are needed to obtain comprehensive information on all aspects of the community as much as possible without perception; in terms of management, security and management forces such as community defense teams and village committees do not have law enforcement powers to enforce mandatory management of various types of personnel. It can be seen that the focus of this type of community security is on people. It requires not only the support of intelligent and precise technical means, but also the linkage between technology and business, such as the public security organs and other powerful law enforcement agencies, in order to realize the intelligent and refined prevention of the community.
2. Commercial and residential mixed community (open community)
Take the commercial-residential mixed community in the open community as an example. Most of these communities are large-scale commercial-residential complexes, and the community often includes apartments (including long-term rentals and hotel-style short-term rentals), outdoor, indoor squares, shopping malls, parking lots, office buildings and other places for multiple purposes. In addition to the characteristics of complex personnel and high mobility of people and vehicles, its commercial attributes also result in dense crowds and high crowd gathering. From the perspective of safety precautions, it is necessary to control points—to clarify the identity and number of actual residents in apartments and short-term rental houses, to discover risks in time, and to control the surface—to monitor the flow of people and the number of people in shopping malls in real time, so as to prevent problems before they happen. It can be seen that the demand for security technology in commercial and residential mixed communities is not only the management of people and vehicles, but also the need for risk identification and abnormal warning based on its characteristics.
3. Property community (closed community)
As for the type of property community in a closed community, due to the closed environment, the application of conventional smart community technical means is effective, and there are perfect property management and security personnel as supplementary management of technical defense measures. For example, when a smoke alarm is triggered in a resident’s home, can the monitoring center quickly contact the owner or resident through multiple channels such as video intercom, telephone, and text message to learn about the situation on the spot and confirm whether it is a false alarm? After confirming that it is not a false alarm, how can it more accurately notify the nearest property management or joint defense personnel to rush to the scene, and how can it quickly link with the corresponding public security and fire departments? more, more stringent security measures will be required). In terms of technology and business, this is far beyond the scope of traditional smart community construction led by property companies and focusing on access management. Can quickly link with the corresponding public security, fire and other departments; how to accurately measure the status of residents in daily operations, and implement different security strategies according to different conditions (for example, during the Chinese New Year, if it is estimated that most of the owners of the community leave the local area and most of the rooms are vacant, stricter security measures need to be implemented). In terms of technology and business, this is far beyond the scope of traditional smart community construction led by property companies and focusing on access management.
The in-depth application of Internet of Things + security in the construction of smart communities
In order to effectively deal with outstanding problems affecting social security and stability, innovate a three-dimensional social security prevention and control system, strictly prevent and punish various illegal and criminal activities in accordance with the law, and comprehensively promote the construction of a safe China, the General Office of the Central Committee of the Communist Party of China and the General Office of the State Council jointly issued the "Opinions on Strengthening the Construction of Social Security Prevention and Control System", which clearly requires all regions and departments to conscientiously implement it in light of actual conditions. In building a three-dimensional public security prevention and control system, the public security organs in Guangdong Province have actively carried out the creation of "one hundred bureaus and one thousand offices" three-dimensional public security demonstration units, accelerated the construction of a safe Guangdong, and proposed a three-dimensional public security prevention and control system based on video big data technology. With the help of the Internet + model, combined with innovative face recognition technology and vehicle recognition technology, it provides public security and the public with various new application modes such as Internet + access control, Internet + vehicle, Internet + vehicle management, etc., effectively improving the ability of public security organs to predict and warn suspicious behaviors and criminal behaviors, as well as the level of rapid response to various incidents. The main content of the construction is "fighting, prevention, management, control, rectification, and service", with the main goal of "continuously increasing the sense of security of the people; increasing the rate of solving major and extraordinarily serious cases, and increasing the people's satisfaction with public security work; reducing major criminal cases, major mass incidents, and major safety accidents".
- Build a multi-source big data aggregation cloud platform through IoT sensing data collection
Based on the Internet of Things technology, through the "Internet +" model, collect face big data at community entrances and exits, expand the scope of face information collection, and analyze personnel activity trajectories, accomplices, travel habits, etc. more accurately; through the "Internet + parking point" model, expand vehicle information collection methods, and comprehensively collect vehicle data at static checkpoints including community parking lots, public parking lots, and maintenance points, including license plate, model, color, and car logos, so as to analyze vehicle trajectories more accurately; build an intelligent perception network to form multi-source social resource big data collection, and build a multi-source big data aggregation cloud platform.
2. Based on video processing technology, build a "video cloud +" big data platform
Based on cloud computing technology, including virtualization technology, distributed data storage technology, programming model, large-scale data management technology, distributed resource management, information security, cloud computing platform management technology, and green energy-saving technology are the most critical, build a basic cloud computing platform to provide massive big data computing capabilities; based on video intelligent processing technology, provide platform-level computing capabilities such as massive video structured processing, intelligent analysis processing, and face recognition comparison and dynamically expanded intelligent analysis services. Massive video structured processing capabilities, extracting structured information such as feature information, vehicle information, and personnel information from videos, and storing the extracted structured data in the video cloud; video intelligent analysis and processing capabilities, obtaining moving target information in videos, and extracting semantic-level event information; face recognition and comparison capabilities, real-time comparison and recognition of received face pictures and face images in the deployed face database, and early warning of discovered suspects.
3. Based on the big data platform, provide three-dimensional public security prevention and control and benefit the people
Guided by the concept of "data culture", promote the association and sharing of police information. Based on the collection and aggregation of multi-source IoT sensing data mainly based on video, and link the data of the public security online business inspection and control system, visual comprehensive system, police comprehensive system, vehicle management and driving system, intelligence system, etc. Increase the value of data, realize the transformation from "passive policing" to "active policing" in the true sense, and realize precise control and fine governance of social security.
Community three-dimensional perception: dynamic and real-time source data is the basic support of the three-dimensional public security prevention and control system. In the activity space of people and vehicles (communities, roads, social areas, etc.), by building and connecting various intelligent sensing equipment (video surveillance, vehicle checkpoints, electronic police, face checkpoint community video surveillance, WiFi hotspots), automatically collect people, vehicles, and electronic track information, and increase the integration of public security business data, social resource data, and Internet data.
Community prevention and control resource library: A large data resource library of prevention and control targets is formed for the objects of public security concern. Personnel big data gathers face information collected at community entrances and exits and social gates; vehicle big data gathers vehicle information at checkpoints, electronic police, virtual checkpoints, and parking lot checkpoints;
Prevention and control cloud platform: build a social resource public cloud platform on the social resource network, access social resources (video recording, access control card swiping, community capture of faces, parking vehicles, electronic tracks, and other information); build a video cloud + platform on the private video network, based on the technical framework of big data, realize fast video structured processing, image analysis, face comparison and other services, and provide elastic allocation of cloud computing and cloud storage resources for upper-level applications.
Comprehensive application of big data for community prevention and control: organically integrate three-dimensional public security prevention and control and precise strikes, combine actual patrols, video surveillance, intelligence research and judgment, command and dispatch, and human-vehicle deployment and control, and intelligence and command linkage; provide various techniques and tactics (location analysis, gang analysis, image search, etc.)
We use the story of the well-received Jiazhuang Village Smart Community in Huangpu District built by Jiadu Technology to demonstrate the in-depth application of the Internet of Things + Security:
Story: Early in the morning, the community police officer Qing of the Dasha Police Station of the Huangpu District Bureau of the Guangzhou Public Security Bureau has already started a new busy day. Before departure, he did not forget to bring the mobile police terminal; on this day, he needs to complete daily tasks such as information collection and site management on the terminal. (Community police’s daily work scene. Person tracing case: The masses call the police on the multimedia alarm column. After receiving the alarm, the police use one person and one file in the system to search for people by face and quickly find the lost child-APP) Since this year, in accordance with the deployment requirements of the Guangdong Provincial Public Security Department and the Guangzhou Municipal Public Security Bureau to promote the construction of smart new policing, Huangpu Public Security has actively explored new community policing work models, and implemented the construction of a smart security community in Jiazhuang Village, Dasha Street, Huangpu District. Jiazhuang Village, located in the east of Kefeng Road, Huangpu District, Guangzhou City, covers an area of 1.6 square kilometers, and is adjacent to Guangzhou Science City, which is known as the "Silicon Valley of South China". Jiazhuang Village is a typical urban village with nearly 10,000 residents, most of whom are migrant workers. The composition of the residents is complex and highly mobile, making management difficult. In promoting the construction of intelligent security community, Huangpu Public Security followed the principles of “technical enclosure, intelligent perception, data surrounding, and intelligent application” and formed an effective enclosure management through the diversion of people and vehicles at the entrance and exit of Jiazhuang Village; at the entrances and exits, key areas, and rental houses, installed face capture machines, intelligent vehicle gates, Wi-Fi hotspots, electronic fences, intelligent access control, multimedia alarm columns, behavior analysis cameras, and sound and light alarm domes. , Practical. (multi-screen display of various data collection, information collection by intelligent sensing equipment, hourly/daily rental housing information collection, rental house administrator collection of rental house information, daily inspection of three small places, road patrol collection)
Existing population management scenario: Integrating the achievement data collected by "four standards and four reals" and multi-dimensional perception data, one file per person is established for the actual population in the community, and the comprehensive correlation of personal related data is realized.
Stranger classification management scenario: For long-term, high-frequency strangers who come and go regularly, the system will identify them as floating population suspected of living in Jiazhuang Village through analysis, and will promptly push them to the community police for real population registration.
Key personnel management and control scenarios: For personnel who come in and out frequently in a short period of time at night, if they are identified as high-risk personnel, they will be pushed to the community police in the form of an early warning to remind them to check the relevant risks and form a record. (The high-risk personnel who check the early warning push on the mobile phone) For the key personnel in the landing control, the system can also assist the police to strengthen daily monitoring and management, and improve the stability and control efficiency. (Case of sales of holidays by key personnel)
Scenario for assessing management level: In order to better assess the level of community population management, Huangpu Public Security has also established an assessment model. One is to comprehensively estimate the actual population of the community by using the registered number of actual population, the number of strangers, and the snapshot information of people and vehicles. The second is to track the changing trend of the registered number of actual population and the number of strangers. When the number of strangers gradually decreases and the registered actual population tends to stabilize, it means that community management has reached a higher level. (The system interface displays the actual population registration number, the number of strangers, and the calculation formula of the snapshot information of people and vehicles, as well as the changing trend of the actual population and strangers). After the completion of Zhigan Security Community, Jiazhuang Village achieved remarkable results in security prevention and control, and the police situation dropped significantly. In 2017, the 110 police situation dropped by 34% year-on-year, and from January to August 2018, it dropped another 17.5% year-on-year.
Create intelligent security and build a safe home together. As the National Excellent Public Security Bureau and the May 1st Labor Award-winning unit of Guangdong Province, Huangpu Public Security will continue to work hard to build a community smart prevention and control system with Huangpu characteristics. It will be at the forefront in the new journey of building the safest, most fair and equitable area with the best legal environment, and will be a pioneer in the drive of reform, opening up, innovation, and accelerated construction of a modern economic system!
Application prospects and trends of Internet of Things + security in the construction of smart communities
Generally speaking, the Internet of Things is divided into perception layer, network layer, platform layer and application layer. The perception layer is mainly composed of chips, sensors, and wireless modules that everyone is familiar with; the network layer is composed of a communication network, and the platform layer includes an application development platform, a connection management platform, a device management platform, and system software development. With the help of tens of thousands of front-end sensors in the perception layer, the Internet of Things can integrate the smart home system in the home, the community's IoT system and services together, and enable community managers, users and various intelligent systems to interact with each other to provide users with a more comfortable "smart" life experience. Only then can the interconnection between various devices in the smart community be ensured, making the community instantly "smart", and it can conveniently and quickly complete many originally complicated affairs, liberating people from community management, and making the entire community management run efficiently. As mentioned at the beginning of the article, where there is illegal parking on the fire escape, which elderly living alone has abnormal vital signs, which road has the manhole cover opened abnormally... etc., the alarm can be realized immediately and on-site maintenance can be carried out in time. In addition, other systems in the smart community, such as building intercom system, smart access control management, parking lot management, parking lot management, sidewalk gate system, elevator linkage, smart security, public broadcasting, and smart door lock subsystems are also distributed with a large number of sensors. They act as "tentacles" that perceive the environment, collect various environmental data and upload them to the cloud, and synchronously analyze and process meaningful data to meet the different needs of different users and discover new application areas and application models. Of course, in addition to the front-end perception layer, a complete and comprehensive big data operation platform is required for centralized management. Through the Internet of Things platform to achieve the convergence of various data, with the help of big data technology to realize data mining, find useful information, and then recommend content to end users. And through the platform display system configuration pop-up window/voice/SMS/log and other information, the staff can conveniently process and follow up the alarm status in real time; even the house number is set in the uploaded map, which is bound to the user. When a danger occurs, the map module of the alarm interface will have the precise location information of the danger. In addition, in order to enrich the functions of the Internet of Things platform, it also has additional value-added functions such as vehicle management, street light management, and O2O of the Internet of Things platform community. thing Enterprises use their own user resources and combine various services provided by the platform to maintain stickiness with users. For example, timely launch the promotion and marketing of smart home products such as smart door locks, provide early understanding of products, installation and use, and later maintenance, and create a new profit model of service + products, which not only provides safe and convenient living experience for owners, but also meets the needs of property management. It is foreseeable that all kinds of video surveillance front-end equipment will realize high-definition and intelligentization of IoT equipment with the empowerment of the Internet of Things. The security business system should follow the practical goal of "seeing clearly, seeing everything, understanding what you see, and seeing it for use". The basic prerequisite for achieving this goal is to deploy intelligent, three-dimensional high-definition acquisition front-ends on a large scale. With the improvement of encoding technology, the current bandwidth of 720P and 1080P streams is within the scope of large-scale applications, and 4K HD is also gradually applied to specific scenarios. To be intelligent and three-dimensional, the scene must be detailed enough, the product types should be rich enough, and the selection and deployment should be matched enough. On the other hand, video surveillance in the security industry has the characteristics of many points, large amount of information, high transmission cost, high cost of large-scale back-end analysis, and delayed analysis timeliness. If a single front-end device has intelligent capabilities, it can not only greatly improve the response efficiency of the entire system, but also reduce the construction cost of the back-end platform. During the construction process, while paying attention to cloud computing, emphasizing the centralized computing and data processing mechanism, technically, we should also pay attention to the marginalization of computing resources and data processing, and pay attention to the characteristics of edge node interaction and communication. Through the edge of computing and data, the dependence of the entire system on the data center is reduced. Using front-end analysis behaviors such as portrait recognition, vehicle recognition, and behavior recognition, the in-depth and refined analysis of video images is gradually advanced. We combine "fog computing" and "cloud computing" to better improve the performance of the entire network. The Internet of Things accelerates the in-depth data mining of smart communities and loads smart brains for data detection. The intelligent front-end equipment with video images as the core content realizes data diversification and three-dimensional detection. However, just collecting and recording information is not enough, and cannot meet the requirements of various business operations for data validity. The validity of data is divided into two aspects: on the one hand, according to mathematical statistics, valid information may only be distributed in a short period of time, that is, the so-called information density, and the higher the density, the greater the value of information; on the other hand, deep mining of huge amounts of data correlates to obtain high-value effective information. Quickly and efficiently transform these view big data into various In order to obtain the valuable information required for this kind of business combat, it is necessary to load intelligent brains for intelligent front-end detection equipment. From "no leakage" to "one out of ten thousand", the former ensures that the goals and clues are recorded, and the latter realizes the goals and clues and actively reveals them. After intelligent perception, the intelligent brain realizes the intelligent mining of massive data value and the intelligent circulation of massive value data, and thus makes the practical application of valuable information possible. The Internet of Things helps to intensively cultivate the video cloud and realize the digitization of actual combat applications. Relying on the proprietary business information network, new video big data applications such as face big data prevention and control, vehicle big data prevention and control, video big data security patrol, video big data intelligence tracking, video big data command and dispatch, video big data investigation and actual combat, etc. are built to realize applications such as video cloud calling, image cloud intelligence, vehicle-related cloud analysis, portrait cloud comparison, comprehensive cloud research and judgment, and policy cloud evaluation. It connects with the application cloud of intelligence, command and decision-making, comprehensive prevention and control, network security sharing, law enforcement case handling, business supervision, mobile applications, online services and other applications of the upper-level platform to realize a wider range of big data integration applications and in-depth video big data applications across business departments, realize application association within the province, cross-city video big data prevention and control, video intelligence analysis, special action command, etc., so as to achieve the purpose of improving early warning and prevention capabilities, public security prevention and control capabilities, and command and rescue capabilities.
Standardized and standardized smart community construction will become a trend. The national emphasis on the Internet of Things has injected a boost to the development of smart communities. The standard issues that have plagued smart communities have recently ushered in a turning point. Ma Hong, director of the IC card application service center of the Ministry of Housing and Urban-Rural Development and deputy director of the National Smart Standards Committee, revealed that the Ministry of Housing and Urban-Rural Development is starting to compile a green smart community standard system, which includes evaluation standards for smart communities and also involves standards for some terminals in the Internet of Things. In his speech, Ma Hong emphasized that a smart city is not about building an information system, but about enabling interconnection among all systems so that data can carry more application value. "Efficient green" and "interconnection" are key considerations in the construction of a new type of smart city. Therefore, in the formulation of related standards, the problem of interface inconsistency will be addressed emphatically. In addition, the National Smart Standards Committee's standards on the construction of green and smart communities have also been released, including the inspection and acceptance of smart community construction, property management, smart door lock security, and home network information platform construction. The Ministry of Housing and Urban-Rural Development and the National Smart Standardization Committee have given key support, including financial subsidies, to the creation of smart communities.
epilogue
Overall, the Internet of Things + security has become a milestone in the construction of smart communities. From the perspective of government managers, many first-tier and super-first-tier cities have had a large population flow and many housing leases. How to ensure smooth information and orderly management is worth thinking about. Community AI can open up relevant data, accelerate the horizontal extension of e-government, fully guarantee the safety of the floating population, and at the same time enable relevant policy information to be uploaded and distributed, improve the government's work efficiency and service capabilities, and enhance the image of governance. From the public's point of view, community AI can change any behavior in the community, including life, learning, entertainment and so on. At that time, the entire community will be like a whole connected network. Through technological empowerment, you can make your life more intelligent, humanized, and convenient, and improve your comfort, safety, and happiness in your life.
In 2019, there is a popular saying on the market side of the security industry: "The one who wins the community wins the world". In the upcoming IOT era of "Internet of Everything", the community, as the core element of the future Internet of Things era that brings together people, houses, and cars in a technological society, its value will be self-evident. Different from the previous smart community construction, with the continuous maturity and application of new technologies such as the Internet of Things, cloud computing, artificial intelligence, and big data, more potential value of the community will be tapped. The community is the last mile offline, a key link in the large-scale Internetization, and an indispensable action for the deployment of offline industries and the Internet of Things. With the presence of industry giants including Ali and Vanke, the emergence of community platform products will become easier. At that time, no matter whether it is an Internet giant, a security giant or a property tycoon, they will not let go of this trillion-level market.
