摘要
介绍了一种运用光电隔离技术来处理程控交换机与PC机的长距离串行通信的实用方案,他特别适用于通信距离较远、干扰较大的场合,尤其在利用已有的部分设备、减少投入方面有着明显的特点。
In this paper, the applied isolation scheme which have solved serial communication between program control exchange and PC is introduced. It can be used in the communication system which have long distance or used in the high disturbance environment, especially it has trait which using a provided part device and reduce cost.
