摘　　要：对每一防区设置不同的地址编码 ,当防区出现警情后发射机发出无线报警信号 ,接收机对设防区的地址编码进行自动识别 ,同时显示出该区的编号并发出警报 .本文介绍无线报警系统的组成及工作原理 ,抗干扰和减小误报率的有效措施 .Giving any monitored area an address, the wireless transmitter sends wireless warning signal when the area has problem . At the same time the receiver can automatically recognize the address of monitored area and display the coded number of the area , then give alarming signal . In the paper the principle and the configuration of the wireless alarming system is introduced, meanwhile the anti-interference measurement and the way to low the error-alarming rate are mentioned .
