The invention relates to a mobile computer redundancy system for a rail transit locomotive; the system comprises two mobile computers, a control manager and a shell for packaging; the two mobile computers are arranged in the shell and are connected with the control manager; the two mobile computers display respective contents respectively when working normally, and when one of the mobile computers fails, the control manager controls the other mobile computer to display the contents of the two mobile computers in a split-screen manner. Compared with the prior art, two computers which are installed separately in the old design are integrated into a left-right parallel whole, and the control manager is added to coordinate the work of the computers, so that accidents caused by display faults of a single computer can be avoided, and the operation safety of the locomotive is improved.
本发明涉及一种用于轨道交通机车的移动计算机冗余系统,包括两个移动计算机,还包括控制管理器和封装用的外壳,两个移动计算机均设于外壳中,并均与控制管理器连接;两个移动计算机正常工作时分别显示各自内容,当其中一个移动计算机故障时,控制器管理器控制另一个移动计算机分屏显示两个移动计算机的内容。与现有技术相比,本发明通过整合老的设计中两台分开安装的计算机为一个左右并列的整体,并通过添加一个控制管理器来协调计算机的工作,可以避免因单一的计算机出现显示故障而造成事故,提高机车运行安全。
