一种对射式红外线传感器控制无线报警的设计

The design of a direct-type infrared sensor to control the wireless alarm

文章介绍的是一种以红外控制的无线报警器,发射电路部分由红外接收电路及PT2262编码器和F05发射模块组成,主要功能是对信号进行采集放大然后经过编码由发射模块发射出去;接收电路部分主要由PT2272解码器和J05接收模块及报警电路组成,主要功能是对接收到的信号进行解码报警;文中采用的是红外对射形式来获取报警信号,误报率极底,并且还设置三个测试通道作为无线收发测试。

What article introduce is that a kind of with the wireless warning apparatus of infrared control, project circuit part from infrared take over circuit and PT2262 encoder and F05 project modular composition, major function is for signal gather to enlarge then pass coding from project modular project to go out; Take over circuit part major from PT2272 decoder and J05 take over modular and report to the police circuit composition, major function is to carry out decode for the signal that taken over to report to the police; What adopt in writing is that infrared for shoot form get alarm signal, rate of false alarm very base, and still install 3 test passagewaies in order to wireless dispatcher tests.
