摘　　要：针对现有的录像机控制器存在控制单一和容易使系统瘫痪的现状,利用单片微型机的串行接口扩展技术,提出了用单片微型机和PC机自动或手动控制录像机的播出,并用红外遥控和多路切换开关对八路录像机进行实时切换和控制的设计。经系统测试和实际应用证明,系统可靠性高。能用多种方法控制多路录像机是设计的一大特点。Aiming at the situation of control simple and system facility paralysis of video recorders controller, serial interface expansive technology of single-chip-microcomputer has been utilized, the design has been proposed that play of video recorders has been controlled automatically or handily by single-chip microcomputer and PC, and eight video recorders has been real-timely switched and controlled by means of infrared remote control or multi-route switching. It has been proved by testing and running that controller has high reliable. A peculiarity of the design is able to control play of multi-route video recorders by multi-methods.
