Research And Implementation Of Fire Remote Monitoring System Based On NB-IoT And OneNET Cloud Platform

Fire safety has a huge impact on human life.With the rapid development of technology and economy,fire safety issues have increasingly become the focus of social attention.Traditional fire equipment management has been unable to meet the needs of today's society.In order to make the fire protection industry more scientific and digital,and to promote industrial transformation and upgrading,the country is vigorously promoting the development of the smart fire protection industry and meeting the development requirements of "Internet + smart fire protection" through intelligent transformation.At present,due to the complex product structure and high development cost,the application field is mainly targeted at large and major fire protection enterprises.The application rate of intelligent fire protection equipment in daily homes and small and micro places is still relatively low,and it has not reached the goal of popular application.Based on this,this article Taking smart fire protection as the research object,applying the latest narrowband cellular IoT NB-IoT wireless transmission technology,combined with the OneNET free IoT cloud platform launched by China Mobile,a remote monitoring system for fire equipment based on IoT technology was designed and developed.The system is based on embedded development technology,combined with the IoT cloud platform,using the latest low-power,wide-coverage NB-Io T wireless communication technology,using the MQTT protocol as the access method,and using the STM32 chip as the main control intelligent terminal.Humidity sensor and smoke sensor realize the data collection and monitoring of fire protection environment.The pipe pressure sensor and voltage sensor installed in the fire hydrant are used to monitor the fire protection equipment.The buzzer is used to implement the site alarm and the relay is used to implement the alarm.The sprinkler device automatically sprays water,and uses a multi-sensor fusion fire algorithm to realize fire alarm reporting and reduce fire false alarms.The OneNET cloud platform is used as a management terminal to control the fire equipment operation in the area in real time and integrate historical data.The Android mobile phone APP for the user terminal realizes the user's real-time monitoring and one-click disposal of fire equipment.The Internet of Things fire remote monitoring system has undergone multiple functional tests and found that the system's functional design is reasonable and various data runs stably.The management department can accurately implement remote real-time monitoring of the fire environment and fire equipment,data statistics,automatic alarm,and timely disposal.Users can use the APP to conveniently and quickly monitor and control their fire protection equipment.This system improves the management efficiency of the management department,saves manpower and material resources,has small development costs,simple and practical functions,can effectively prevent the loss of economic property caused by hidden fire hazards,and is more suitable for domestic fire protection and small,medium and micro enterprises.The application of domestic smart fire protection It is of great significance to make it widespread.
