介绍一种新型小区防盗系统的设计原理和方法,该系统由计算机、集中控制器、收发器和多个采集器组成。集中控制器、收发器和采集器采用ATmega8单片机作为主控芯片,各个组成部分之间采用灵活的通信方式,不但提高了传输的可靠性,而且降低了整个系统的陈本,在一些智能小区已经得到了较好的应用。 This paper introduces the design principle and method of a new residential anti-theft system. The system consists of a computer, a centralized controller, a transceiver, and multiple collectors. Centralized controller, transceiver and collector adopt ATmega8 one-chip computer as the main control chip, each component adopts the flexible communication mode, not only improved the reliability of the transmission, but also reduced the whole system of Chen Ben, in some intelligent communities already Get a better application.
