基于MQTT协议的电气火灾监控系统设计

Design of Electrical Fire Monitoring System Based on MQTT Protocol

提出了一种基于MQTT协议的GPRS电气火灾监控系统,主要由火灾探测器和阿里云物联网平台组成。基于Modbus协议的RS-485串口与上位机通信来对探测器进行出厂参数初始化、校正。搭载GPRS模块,通过MQTT协议实现探测器与阿里云物联网平台之间的数据传输。将探测器采集的现场用电设备的实时用电数据与状态上传到云端服务器,可通过手机或电脑等移动设备登录APP客户端实时查看现场用电设备的用电情况,并可对探测器进行远程控制。

The GPRS electric fire monitoring system based on MQTT protocol was proposed,which was mainly composed of detector terminal and Alibaba Cloud IOT platform.RS-485 serial port based on Modbus protocol communicated with the host computer to initialize and correct the factory parameters of the detector.With GPRS module,the data transmission between terminal and IOT platform was realized by MQTT protocol.The real-time power consumption data and status of field power equipment collected by detector terminal were uploaded to cloud server.The mobile devices such as mobile phones or computers can log on to APP client to check the power consumption of field power equipment in real time,which can realize the remote control the detector.
