电气火灾监控探测器的设计

Design of Alarm and Control Detector for Electric Fire

设计了一种基于MCU微处理器的高灵敏度智能型电气火灾监控探测器。设计中采用实时交流采样算法对剩余电流进行信号处理,检测精度高,减少了系统漏报、误报等情况。该探测器采用模块化设计,便于集成与拆分,更新升级简单,可以实现剩余电流式和测温式两种探测器的所有功能,为常规的低压配电网络的电气火灾监控系统提供了强有力的支撑。

An alarm and control detector for electric fire with high sensitivity and intellectuality based on MCU was designed.The real-time AC sampling algorithm was adopted to signal process residual current.The detection rate was accuracy and could reduce the misinformation and missing report.The detector was modularly designed,which was easily integrated,split and updated.It could realize both function of residual current and temperature measured detectors,so as to offer support to alarm and control detector for e...
