基于AT89C51单片机在燃气报警中的设计及应用

摘要

This system includes two parts:hardware and software. It implements the detection and emergency treatment of the alarm of the excessive gas concentration by AT89C51 single chip microcomputer. If the concentration is greater than the set threshold, it will drive the circuit to give the sound and light alarm, and open the emergency system to eliminate the hidden dangers.%该系统设计包括硬件和软件两部分。主要是基于AT89C51单片机实现燃气浓度超标报警的检测和应急处理，如果浓度大于设定的限值就驱动电路进行声光报警，并开启应急系统消除隐患。
