perception infrastructure
The perception infrastructure architecture consists of four aspects: perception scope, perception means, access mode and perception network. Through perception methods such as video, mobile terminals, and radio frequency technology, intelligent, comprehensive, and in-depth monitoring of municipal infrastructure, transportation, water affairs, environmental protection, education, culture, medical care, community, logistics, urban management, public safety, and tourism Perception, the collected information is extended and expanded through wired/wireless transmission technology, and connected to the network layer for transmission, forming a multi-type perception network.
Sensing infrastructure should give full play to the functions of urban digital information collection and monitoring, and carry out comprehensive monitoring of cities composed of basic municipal facilities, basic urban entities, moving commodities and objects, urban resources and environment, and individual and groups of urban residents. Comprehensive and in-depth perception, forming an intelligent interconnected perception network covering urban components, including urban ecological environment perception, lifeline monitoring, traffic supervision, building facility monitoring, public facility monitoring, etc., to achieve indoor positioning and comprehensive application for smart cities And construction provides an intelligent, ubiquitous information perception network, reflecting the XX smart city "everyone is a sensor, everyone is a camera".
Construct a sensing information infrastructure covering the urban area of XX, fully consider the needs of various fields in XX City for sensing types, coordinate the layout of sensing facilities in the city, and build an information sensing network that serves the overall situation in a unified manner, avoiding duplication of similar sensing facilities in smart fields Under the principle of construction, several city-level perception networks with general perception methods as the core will be formed. Focus on building video perception networks, GPS perception networks, wireless perception networks, digital cluster private networks, and integrated sensor networks that have large-scale applications, multiple fields, wide ranges, and centralized sensing methods.
While planning the sensing infrastructure, it is necessary to fully consider the scalability of various types of Internet of Things and the forward-looking development of sensing technology, as well as the compatibility of sensing devices and the standardization of information.

Based on the overall planning of the distribution of sensing facilities within the city of XX, the principle of centralized construction of IoT sensing applications that serve the overall situation, and to avoid repeated construction of similar applications in the smart field, the following types of sensing networks will be focused on:
(1) Video perception network
Based on the distribution of 250,000 video surveillance equipment in XX City, further expand the scope of video perception, and incorporate areas such as building internal monitoring, suburban open environment monitoring, and enterprise factory park monitoring into the urban video intelligent monitoring system to form a video sensor network. On the basis of high-definition video, the application of image intelligent recognition is added, and it is intelligent in the aspects of abnormal behavior pattern recognition, leftover object alarm, sudden running, and facial feature recognition. The data collected by city-level video intelligent monitoring and perception can be shared with fields such as smart public safety, smart transportation, smart environmental protection, and smart logistics.
(2) GPS perception network
Build a GPS sensing network for vehicles, special items, and specific groups of people within the city of XX, and effectively monitor the positions and moving trajectories of moving people and objects. XX Municipal Transportation Commission has preliminarily built the GPD vehicle movement tracking system in the transportation industry, and the vehicle perception network has basically been formed. Taking the vehicle perception network as the demonstration and basis of GPS positioning, expanding the scope of positioning to special items (inflammable and explosive materials, dangerous goods, etc.) Public security, smart urban management, smart logistics, smart medical care, etc. provide real-time geographic information services.
(3) Wireless Perceptual Network
Build a wireless sensory network that uses mobile phones, notebooks, tablet computers, POS machines or other handheld devices as sensing methods. The mobile terminal transmits the acquired information including positioning information, picture information, fingerprint information, ID card information, barcode scanning information, RFID scanning information, IC card scanning information, etc. to the information processing layer through the wireless network, so as to realize the effective transmission, sharing and storage of information . The wireless sensory network provides the government with mobile law enforcement, and provides the citizens with the functions of mobile inquiry, mobile office, and mobile commerce.
