摘　　要：随着无人值班变电站不断增加,必须对其设备运行状况进行实时监控,因此,要求通信远动通道有很高的可靠性。文章分别从数字通道、模拟通道和电话通道等方面介绍了远动通道自动检测装置的工作原理和检测功能,并给出其软件设计流程图。利用这种装置,运行人员能及时掌握远动通道的情况,从而提高通道的运行率。With the increase number of unattended transformer substations, it＇s necessary to monitor and control the status of equipment operation in substations in real-time. So the reliability of teleeontrol channel is very important. The paper introduces the principle and functions of automatic detection equipment for teleeontrol channel from digital, analog and telephone channels respectively and puts forward its software design flow chart. With such equipment, the status of teleeontrol channel can be monitored by operator promptly and the operation rate of channel can be improved apparently.
