摘　　要：冶轧实验室采用天然气辐射采暖,天然气泄漏和不完全燃烧产生的CO极易导致火灾和爆炸等安全事故。文章开发了一款无线、低成本的易燃气体检测系统,该监测系统以STM32F103系列单片机作为主控系统,使用MQ-2和MQ-7气体传感器监测车间内的甲烷和CO浓度,使用SHT30温度、湿度传感器监测车间内的温度、湿度,使用Bluetooth蓝牙模块将传感器采集的数据传输至手机端。手机端搭载Android操作系统,实现对数据的处理和分析,满足了冶轧实验室对使用易燃气体进行监测的要求。The heating in smelting and rolling laboratory is with natural gas radiation as well as the CO generated by natural gas leakage and incomplete combustion can lead to such accidents as fires and explosions very easily.In the article,a wireless and low-cost detection system of flammable gas is developed,which is with the STM32F103 series single chip computer as main control system.The concentrations of methane and CO in workshop are monitored with MQ-2 and MQ-7 gas sensors,temperature and humidity in workshop are monitored with SHT30 sensor of temperature and humidity as well as the data collected by sensors is transmitted to mobile terminal with Bluetooth module.The data processing and analysis are realized with mobile terminal and Android operating system,which could meet the requirements of monitoring flammable gas used in smelting and rolling laboratory.
