基于短距离无线/有线通信的燃气监测报警系统

摘要

According to the gas monitoring requirement of combustible gas leak-prone area,a gas monitoring and alarm system based on short-range wireless/wired communications was proposed.In this system,we designed the wireless/wired gas monitoring and alarm terminal using generic combustible gas sensor,temperature sensor,8-bit microcontroller and 433 MHz RF-Transceiver chip as the core devices.Furthermore,PC monitoring software was designed for practical application.The gas monitoring and alarm system can monitor real-time gas concentration and temperature remotely.It has the function of dynamic display,historical data query and alarm.%根据燃气泄漏多发区域对燃气浓度监测的需求,提出基于短距离无线/有线通信的燃气监测报警系统.系统选用通用的可燃气体传感器和温度传感器、8位单片机和433 MHz无线通信芯片为核心器件,完成无线/有线燃气监测报警终端的软硬件设计,设计完成了接收终端和上位机监控软件.燃气监测报警系统能对燃气浓度和环境温度远程实时地进行监测,具有动态显示、历史数据查询和二级报警等功能.
