气体传感器在消防网络中的应用

Application of the gas sensor in the fire protection network

采用气体敏感元件QM—N5与单片机AT89C2051构成有害气体监测系统,介绍了系统设计方案以及传感器电路组成与工作原理,设计了系统软件.测试结果表明,该系统对烟雾、甲烷、乙烷等有害气体具有较高的灵敏度,可用作消防网络的监测与报警.

The constitution of surveillance nocuous air system adopts gas sense organ QM-N5 and SCM AT89C2051 is introduced, and the design proposal based on it is described, along with buildup of sense organ circuit and operation principle. Based on design of software system, test result indicates the system possesses high sensitivity to tolerance for fog, firedamp, ethane, nocuous air, etc. The system of fire protection network is used for surveillance and alarm.
