摘　　要：文章以接入集控站系统为例,原有的远动常规数字传输通道存在着过程环节多、通道中断后恢复时间较长等弊端,本文介绍了数字通道的多种设计方案,并对几种方案的实际运用情况进行分析和比较,多种数字通道传输可有效提高远动系统可用率指标,并考虑了在集控站前置系统如何接入多通道和SCADA中处理多数据源的问题。This article is using connecting a concentrator station system as an example, to introduce a few design solutions of digital channels. The regular original remote interacting digital transmitting channels has too many components, and it takes a long time to reinstall after breakdown. The solutions introduced here have been put into use in real situations. We will analyze the collected data to prove that multi kind digital channels could improve remote interacting systems＇ availability. We also considered how to install multichannels into concentrator station＇s presystem and using SCADA to process multi data sources.
