摘　　要：传统变电站分站系统通信管理机或远动设备多采用RS232接口形式,都是通过全双工串行口进行点对点的通信。本文所述的装置克服了传统全双工串行口点对点通信的技术壁垒,通过外接电路设计,实现了在不增加外接电源情况下,单一串口可与多个主站串行通道进行同时连接,并通过全双工模式与多个主站在线实时通信,解决了厂站端通过单串口与主备调系统同时通信问题,具有普遍推广意义。Traditional substation system communication management machine or remote equipment mostly using RS232 interface ,by full duplex serial port for point- to- point communication. Described in this article the device overcomes the traditional point-to-point full-duplex serial port communication technology barrier, through an external circuit design, the power converter is achieved without any increase in cases, a single serial port can be connected with multiple host serial channels at the same time, and through the full duplex mode with multiple host online real-time communication, solve the station side through single serial port communication problems at the same time, with the Lord for the system has the great significance of the populari- zation.
