数字电路自动切换系统在引滦局的应用

摘要

为使通讯线路出现故障时，能够自动切换电路，海河水利委员会引滦工程管理局建设了数字电路自动切换系统。介绍自动切换系统建设的目标和实施方案，分析自动切换系统在引滦工程管理局的应用。实际应用表明，自动切换系统能满足设计要求，具有自动及人工强制无损伤切换功能。%　　An automatic digital circuit switching system is constructed by administration bureau of Luanhe River to Tianjin City water diversion project of Haihe river water conservancy commission to realize automatic circuit switching when a fault occurs on the communication link. The article makes an introduction on objects and implementation scheme for the system, and analyzes its application. Its application shows that the system can meet design requirements, possesses automatic switching function and function of forced manual switching without getting injured.
