摘要
电路中的触点、开关处由于种种原因引起了火花,提出利用光纤的传递使光电二极管电阻下降,经电路处理并发射无线电波报警,来实现触电火花的检测。并通过无线电波接受装置,设计出多路预警电路,可实现多处不同位置的远程报警,利用一台报警器报警显示多个构成单位区域内的情况。
The electronic contact and the switch place in electric circuit have caused the spark for various reasons.The resistance of photorectifier decline is proposed through optical fiber,electric circuit launch radio wave warning,and it realized the detection of electronic contact spark.And the multi-early warning circuit is designed,which can achieve different locations in remote alarm.A alarm apparatus may demonstrate many regions.
