本设计方案中,设计思路为围绕着单片机和燃气传感器进行本次硬件系统的设计。其中使用单片机连接着各个设备。燃气传感器检测空气中被测气体的浓度,通过A/D转换器把转换的数据传输到单片机中由单片机进行数据的分析处理,产生相应的报警电路运行。此次报警系统通过信号采集模数转换模块收集气体浓度、然后通过A/D转换器转换成数字信号,之后由单片机控制模块进行分析、在字符显示模块进行数据显示、如果被测气体超标激活声光报警模块进行报警和然后在进行安全保护模块。
In this design, the design idea is to design the hardware system around the single chip computer and gas sensor. Each device is connected with a single chip computer. The gas sensor detects the concentration of the detected gas in the air, transfers the converted data to the MCU through the A/D converter, and analyzes and processes the data by single chip microcomputer, so as to generate the corresponding alarm circuit. The alarm system module to collect gas concentration, and then through the A/D converter into a digital signal through the signal acquisition and analog digital conversion, followed by the MCU control module, analysis module in the data display, if the measured gas exceed the standard alarm module for alarm activation and then in the security module display character.
