Problems solved by technology

[0003] At present, the display screens of the train control system and the network system in the train are only responsible for displaying the information of their respective systems, and cannot realize mutual switching and redundancy
If any display screen fails during train operation, it will not be able to display the corresponding information that the display screen needs to display, which will easily cause great safety hazards

Abstract

The invention discloses a method for mutual redundancy of train display screens. The method includes: judging whether a first display screen fails or not; if yes, determining display information of the first display screen; and displaying the display information of the first display screen on a second display screen. The first display screen serves as a train control system display screen or a network system display screen; when the first display screen serves as the train control system display screen, the second display screen serves as the network system display screen; and when the first display screen serves as the network system display screen, the second display screen serves as the train control system display screen. Mutual display of the train control system display screen and the network system display screen in a train can be realized, and the safety factor in the running process of the train can be further increased.

Description

technical field [0001] The invention relates to the technical field of mutual redundancy of display screens, and more specifically relates to a method and a device for mutual redundancy of a display screen of a train operation monitoring system and a display screen of a train network system. Background technique [0002] At present, there are mainly train operation monitoring systems and train network control systems in trains. The train operation monitoring system is mainly used to detect the signal position, bridge, slope, crossing, speed limit and other information in front of the train, and display the detected information on the display screen of the train operation monitoring system in the form of graphics, symbols, text, curves, etc. (referred to as the display screen of the train control system); the train network control system is mainly used to detect the information of the on-board equipment, and display the detected information on the display screen of the train ...
