本文借鉴计算机网络的基本思想，将传统的视频闭路监控及控制方式设计为以单片机组成系统控制网络。通过通讯网对各监视点进行联络控制，将系统的众多的视频监控信号线和控制信号线合为两种信号总线，即视频信号总线，控制信号总线。每个监视终端机将视频信号输出并接于视频信号总线上，其控制信号挂接于控制信号总线上。这样使整个系统信号连接线清晰，便于实行标准化安装。且减少投资，有利今后维护
This article draws on the basic idea of computer network, the traditional video closed-circuit monitoring and control methods designed to form a single chip system control network. Through the communication network of the various points of contact control, the system of many video surveillance signal lines and control signal lines into two kinds of signal bus, namely, video signal bus, control signal bus. Each monitoring terminal outputs and connects the video signal to the video signal bus, and the control signal is connected to the control signal bus. This makes the entire system signal cable clear, easy to implement a standardized installation. And reduce investment, favorable future maintenance
