摘要
介绍了TDCS(列车调度指挥系统)车站分机双机热备系统的设计方案。该系统由2套独立供电电源PWR、2套网络处理控制器NPC、2套开关量采集板DIB和1块双机热备切换板STBY组成,实现了站场码位采集、串口通信、网络通信等的双机热备功能,提高了TDCS整体的可靠性和可维护性。
A dual-redundant LDTS （Loocal Data Transmission System） standby system of TDCS is introduced. It consisted of two sets of independent power supply, two sets of NPC, two sets of DIB and one piece of STBY switcbover board for dual-machine hot standby. TDCS＇s reliability and maintainability was improved by realizing dual-machine hot standby functions of station code acquisition, serial interface communications and network communications etc.
