The invention discloses a train LCU control system based on double 2-vote-2. The system comprises a first main control board, a second main control board, a plurality of VIO board groups, a pluralityof DIO board groups and a communication board, the first main control board, the second main control board, the communication board and each VIO board are respectively provided with two control units,the two control units of each board are in communication connection through an in-board communication bus, and the control units of each board are in communication connection through an inter-board communication bus. According to the invention, redundancy processing of data acquisition of each IO board and cascade control commands of the communication board can be realized, the reliability of execution of the output control commands and the cascade control commands is improved, and safe and stable operation of a train is ensured. And the dual-power board supplies power to each group of boardcards independently and supplies power to the communication board and the storage board redundantly, so that the power supply stability of the system is improved.
本发明公开了一种基于二乘二取二的列车LCU控制系统,包括第一主控板、第二主控板、若干VIO板组、若干DIO板组和通信板,第一主控板、第二主控板、通信板和各VIO板均设有两个控制单元,各板的两个控制单元之间均通过板内通信总线通信连接,各板的每个控制单元之间均通过板间通信总线通信连接。本发明可实现对各IO板采集数据、通信板级联控制命令的冗余处理,提高了输出控制命令和级联控制命令执行的可靠性,保证列车的安全稳定运行。双电源板为每组板卡单独供电,同时双电源板为通信板和存储板冗余供电,提高了系统供电稳定性。
