基于51单片机多功能报警接收控制器的设计

Design of multi-function alarm receiving controller based on 51 single-chip microcomputer

随着微电子、计算机技术以及通信技术的迅速发展,由单片机和无线传输模块组成的无线数据通信系统在安防等行业的无线控制、数据采集、故障报警等诸多领域中得到越来越广泛的应用。针对目前市场上的家用网络摄像机只有一个报警输入接口,而用户实际需要接入多种报警源(防火、防盗、防抢)的问题,设计了可以接入多种报警源且任意I/O口都可以接受无线信号进行解码的报警接收控制器。

With the rapid development of microelectronics, computer technology and communication technology, wireless data communication system composed of MCU and wireless transmission module for security industry wireless control, data acquisition, fault alarm is applied more and more widely in many fields. Aiming at the problem of the current domestic network cameras on the market only has one alarm input interface, but actually users needs to access a variety of alarm source （fire, theft, robbery）, we design an a^tarm receiving contro｜ler to access multi-alarm source and receive wireless signals in any I/O port.
