一种利用G.703数字接口传送远动信息的新方法

A New Method Using G.703 Digital Interface to Transmit SCADA Information

随着变电站自动化程度越来越高,设备越来越多,需要传输的自动化信息量也随之越来越大,仍利用原有的Modem模拟传输方式,已不能满足日益发展的需要,对信道资源也是一种浪费。通过数字接口转换装置,利用通信设备的G.70364K同向数字接口直接传输数字信号,不再经过模拟转换。传输速率可提高到4800～64Kbit/s,并可提供10BaseT网络接口,组建各种数字通信网络。

With the increasing level of power substation automation and the increasing number of equipment, the information amount need to be transmitted is getting larger. The traditional analog transmitting mode using Modem not only can't meet the requirements any more, but also waste the communication channel resources. Through digital transferring interface transfer device and using G.703 64K unidirectional digital interface to directly transmit digital signals is not need of analog transfer. The transferring rate can be lifted as high as 4 800～64K bit/s, and can provide 10BaseT network interface, and can set up various digital communication networks.
