新型可燃性气体报警仪的研制

Development of a New Type Combustible Gas Alarm Apparatus

摘要:

介绍新型可燃性气体报警仪的设计,可用于对丙烷、丁烷、氢气及其他可燃性气体的检测,用于检测可燃气体爆炸性；采用C8051F020单片机,通过2M007型电阻式气敏传感器采集信号,经过放大电路放大,传入单片机,进行模数转换,采用算术平均滤波对数据过滤,再通过一系列的数据处理,显示可燃性气体浓度,通讯方式采用以sim300通讯模块的GPRS通讯的新型可燃性气体报警系统；软件设计采用C语言编程,灵活方便、具有强大的移植性；如空气中可燃性气体浓度超标,开始报警,显示屏上显示出大于阀值的可燃性气体浓度,且通过无线通讯使手机也正常收到了报警短信；该系统功能齐全,操作简便,具有很高的应用价值。

Abstract:

This paper Introduces a new type of combustible gas alarm system whose main controller is C8051F020 ,it is through bridge circuit measurement signal and differential amplifier circuit amplifier, then the arithmetic average filter is adopted to data filtering, and through a series of data processing, display of combustible gas concentration. Its communication is based on sim300 GPRS communications module communication . The system is simple, and fully functional, and it has the very high application value.
