摘要
本文介绍用于高压输电线路上防止鸟害的电子防鸟报警系统,本设计以热释电红外传感器作为检测部件,检测外界信息,并转换输出微弱的电信号,经运算放大器、A/D采样、单片机处理,滤去干扰,最后所得信号触发报警电路。
In this paper, an electric bird driven system used on high voltage transmission line is introduced. The system in the following uses a thermoelectric infrared transducer as the detecting unit, sensing outside information, and also transferring it into tender electric signals, which will be magnified and sampled by AD and handled by single chip computer. At this time the interference in the signal will be sifted by the anti-interference circuit. And then the remaining signals are used to drive the alarm system.
