摘要
针对目前城市火灾监测技术的现状,设计了基于窄带物联网(NB-IoT)技术的无线智能火灾监测与报警系统。采用STM32作为火灾监测终端节点的控制器,设计了终端节点电路,进行火灾各参数的监测;采用物联网通信模块BC20作为通信节点,实现控制器与通信模块的数据交换;采用MQTT协议实现通信模块与云服务平台之间的数据通信;设计Web端和手机App软件,与云服务平台进行通信,并实时监测终端节点的状况。该设计降低了目前城市火灾报警系统的运行成本,实现了对火灾监测点的实时无线监控和报警,为打造智慧城市和数字中国提供技术支持。
In view of the current status of fire monitoring technology,a wireless intelligent fire monitoring and alarm system based on NB-IoT technology is designed.By using STM32 as controller,the terminal node circuit is designed to monitor the fire parameters.The Internet of Things communication module BC20 is used as the communication node for data exchange between controller and BC20 module.MQTT protocol is adopted to realize data communication between BC20 module and cloud service platform.We designed Web terminal and mobile App software to communicate with cloud service platform,and monitor the status of terminal nodes in real time.This design reduces the operating cost of current urban fire alarm system,realizes real-time wireless monitoring and alarming of fire monitoring points,and provides technological support for the construction of smart city and digital China.
