1. Industry background
In recent years, frequent fires have caused great loss of personnel and property. The State attaches great importance to it and has successively issued relevant documents to clarify relevant requirements and implement fire safety responsibilities. The Ministry of Public Security, the Ministry of Civil Affairs, the Office of the National Working Committee on Aging, and the China Disabled Persons ’Federation and other six ministries and groups jointly issued the" Guiding Opinions on Actively Promoting the Fire Prevention and Control of Independent Smoke-sensing Fire Detectors "(公 消 [2015] No. 289), clearly pointed out: nursing homes, welfare homes, service institutions for the disabled, support services for the poor, kindergartens and other elderly, disabled and children buildings, home care for the elderly, "empty nest elderly", scattered elderly care for the poor and other crowds , Community comprehensive service facilities and other community residents ’activities, located in shantytowns, urban-rural junctions, traditional cultural villages and old residential houses with fire resistance grade three and below, dormitories, rental houses, farmhouses, small hotels, underground living spaces It is advisable to promote the installation of independent smoke detectors in places with frequent fires; encourage the installation and use of independent smoke detectors in other residential houses. The document also pointed out that in areas where the independent smoke alarms are relatively concentrated, it is possible to explore the selection of networked products and send prompt messages such as text messages to auxiliary devices such as remote displays and guardians and managers.
The State Council issued the "Notice on Several Recent Fire Accidents" on December 4, 2017, which put forward higher requirements for fire safety work. The document pointed out: All regions should strengthen the investigation of fire hazards in the "three-in-one" and "multi-in-one" buildings and group rented houses integrating production, operation, storage and accommodation according to the actual situation. An independent fire alarm detector is installed, and a full-time administrator's night inspection measures are implemented. If there are more than 30 people staying, all fire-fighting facilities such as automatic fire extinguishment and fire alarm shall be installed according to the standard, and it shall be clearly designated to be responsible for fire management.
With the gradual improvement of people's fire awareness, the independent smoke sense has been popularized to a certain extent, and it has played a role in fire prevention and disaster reduction. However, due to the limitations of independent smoke products, the quality of independent smoke products on the market is uneven, with a single function, and only sound and light alarms can be issued. The alarm information cannot be received when people are not present, and the working status cannot be grasped in real time. With the promotion of "smart fire protection" across the country, the traditional independent smoke sensor can no longer meet the new market demand, and with it, new smart smoke sensor solutions are coming.
Second, the solution
Through comprehensive analysis of the problems in the fire alarm industry and the common pain points of traditional independent smoke, and combining the characteristics of wireless communication technologies such as LoRa and NB-IoT, we have proposed different wireless based on cloud, tube, and terminal collaborative development. Smart smoke solution for communication.
(1) LoRa smart smoke solution
The LoRa smart smoke sensor is embedded with the LoRa star networking module WH-L102-LC and works with the LoRa concentrator USR-LG220-L self-organizing network. The data is reported to the LoRa concentrator through the LoRa module. The 4G communication method uploads data centrally to the cloud service monitoring platform. This solution is suitable for campuses, factories, shopping malls and other places with many monitoring points and centralized locations. It has the advantages of high data security, low communication costs, and flexible deployment.
(2) NB-IoT smart smoke sensing solution
The NB-IoT smart smoke-sensing solution is built according to the cloud, pipe, and end system architecture. The terminal equipment integrates the NB-loT standard module and connects to the NB-loT base station to achieve communication. The intelligent terminal uploads the information through the NB-loT base station. Give cloud service monitoring platform. The program is suitable for nine small places, nursing homes, ancient buildings, rental houses and other places. The program has the following advantages:
Three, program advantages
Stereo alarm, multi-party push: After detecting a fire, stereo alarm through detector, platform, mobile APP, SMS, and phone, and simultaneously push the alarm, fault and other information to fire supervisor, community grid member, property management personnel, Fire safety responsibility subjects such as miniature fire stations.
Real-time monitoring and elimination of hidden dangers: Smart smoke detectors are online in real time, monitoring the status of smoke detection 24 hours a day, and real-time control of hidden dangers such as alarms, faults, and power shortages, which facilitates the management and maintenance personnel to eliminate hidden troubles at the first time The smoke working state is normal and effective.
Super battery life, chain alarm: NB-loT smart smoke sensor adopts low power consumption communication module to ensure the normal continuous power supply of the battery for more than 5 years; smoke sensor information is managed by the cloud platform, and the smoke sensor adjacent to the alarm point can be chained Alarm, notify neighbors, evacuate in time to avoid greater casualties.
The platform is sound and convenient to manage: the platform has super PaaS capability, complete functions, open API interface, and can seamlessly connect with multiple devices. The technical means of collaborative management of smoke, mobile phones, and platforms are more convenient for the supervision of competent authorities.

4. Industry Application
Smart smoke sensing is based on high-precision positioning, combined with big data, cloud smart fire fighting platform, Internet of Things and other technologies. Through the intelligent upgrade of fire fighting work, the efficiency of fire rescue is improved, which helps enhance its value and practicality. Smart smoke is constantly extending to various scenarios of smart homes, smart communities, smart campuses, smart factories, smart hospitals and smart cities.
