红外线电子防护网设计

Design of Infrared Electronic Safeguard

主要介绍一种由振荡电路、计数器、译码器、红外发射及接收电路、编码器、比较器、报警电路等组成的红外线电子防护网系统。整个设计结合数、模电子设计方法,将系统总体方案分割成若干相对独立的功能部件,直接选择合适器件,然后按功能要求拼接组合构成完整的数字系统,并进行仿真。结果表明方案完全达到设计要求。

The infrared electronic safeguard system, which mainly consists of monofier, counter, encoder, emitting ＆ receiving circuit, comparator, alarrning circuit, are introduced in the paper. The whole project is parted as some relatively unattached units by means of design method of simulant＆digital technology, the right elements are selected to build up the whole system in the light of fimction request,then the system has been simulated. The result indicates that the project completely accords with request.
