摘要
设计一种基于公共电话网的天然气报警系统。以SPCE061A单片机为控制单元,通过扬声器或电话对异常情况发出报警,具有实时监测天然气泄漏,实时跟踪显示现场天然气浓度,以及根据语音报警及其报警状况自动关闭天然气管道电磁阀并开启排气装置等功能,实现了自动检测、自动报警、自动处理警情全过程自动化。经实验证明,该系统具有实用性强,可靠性高,灵活性好,便于扩展等优点。
A natural gas alarming system based on PSTN is designed, using SPCE061 A single chip microcomputer as control unit, alarming certain abnormal phenomena through speaker or telephone. The system possesses such functions as monitoring natural gas leakage all the time, displaying the density of natural gas at the scene all the time, alarming with speech and turning off natural gas and exhaust or not etc. And it realizes monitoring automatically,alarming automatically and dealing with the abnormal phenomena automatically in the whole process. It proves that the system is reliable,flexible and easy to extend.
