Research On The Application Of NB-IoT Technology In Fire Monitoring

The construction of the Internet of Things in China is advancing rapidly.In response to the national guidelines for "smart fire protection",the combination of fire protection and Internet of Things technology is an inevitable trend.The traditional fire monitoring system is mainly wired and requires a large number of alarm pipelines to be laid.Its shortcomings such as difficulty in construction,high cost,and close coverage are reflected.The paralysis of fire protection in old communities and the demands of fire protection monitoring in remote towns and villages have forced us to propose new solutions for fire protection monitoring.NB-IoT(Narrow-Band Internet of Things)technology belongs to the low-speed Internet of Things.It has the performance advantages of large connection,low cost,low power consumption,and wide coverage.It is widely used in smart agriculture,remote meter reading,etc.It is the target of a large number of industries.NB-IoT communication technology can share existing 2G,3G,and 4G networks without rebuilding base stations,reducing development costs.This design proposes to apply NB-IoT communication technology to the fire monitoring system,combining NB-IoT communication module,microcontroller and temperature,smoke and other sensors to form a terminal device for real-time monitoring of data such as temperature and smoke in the environment;The NB-IoT base station and communication protocol realize the data transmission between terminal equipment and the IoT cloud platform.The IoT cloud platform can record the status,data,trend,etc.of fire protection monitoring in real time,and realize the fire alarm by setting the alarm threshold;the client can respond in time Cloud platform threshold alarm,and log in to the IoT cloud platform through the PC or mobile terminal to view current and past fire monitoring data.The current IoT cloud platform is developing rapidly,has complete functions,and is very friendly to developers.This topic pursues low power consumption,low cost,convenient development and management and other factors,realizes the wireless communication of the fire monitoring system,and simplifies the development cost and construction difficulty.The fire-fighting monitoring system designed and constructed in this design has been tested to meet the requirements of fire-fighting monitoring.The system is stable and does not require large-scale cable laying.It is suitable for fire-fighting projects with difficult networking and provides help for the creation of "smart cities and smart Internet of Things".The paper has 34 maps,9 tables,and 50 references.
