摘要
为了能够实时监控室内天然气泄漏情况,采用半导体MGS1100传感器为数据采集元件,以STC89C52单片机为主控核心,设计了一种天然气报警系统。系统根据环境做出判断,自动开启排气装置和报警装置,实现了自动报警、自动处理警情、自动检测。具有实时跟踪显示被测环境天然气浓度,实时监控天然气泄漏。经实验测试表明,该系统可快速准确的检测出空气中煤气的浓度,测量精度达到3%,适应各种场合煤气浓度报警,硬件部分具有可靠性高、实用性强、便于扩展等优点。
In order to be able to real-time monitoring of indoor gas leakage,the semiconductor MGS1100sensor element for data,based on STC89C52single chip microcomputer as control core,the design of a gas alarm system.System to make the judgment according to the environment,automatically open the exhaust device and the alarm device,automatic alarm,automatic processing,automatic detection alarm automation of the whole process.With real-time tracking display the indoor gas concentration,real-time monitoring of natural gas leakage.The experimental results showed,detect the concentration in the air gas the system can quickly and accurately,the measurement precision can reach 3%,suitable for various occasions gas concentration alarm,the hardware has the advantages of high reliability,strong practicability,easy to expand etc.
