Embodiment Construction

[0036] The following describes the technical solutions of the present invention clearly and completely with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0037] Such as figure 1 As shown, a method for fault diagnosis, storage and display using a train display screen provided by the present invention includes the following steps:

[0038] 1. According to the number of failures of each subsystem of the train, match the network setting port of the corresponding size for each subsystem. Each data bit in each byte of the network setting port corresponds to each fault of the corresponding subsystem one by one.

Abstract

The invention discloses a method and a system for fault diagnosis, storage and display by applying a train display screen. The method comprises the steps of judging whether a fault occurs in a whole vehicle and a vehicle-mounted subsystem or not according to the change of each data bit of a network setting port; and when a fault occurs in one subsystem, writing corresponding fault information intoa file in a BIN format and storing in a display screen flash memory, so that diagnosis, storage and display of the train fault can be carried out accurately in real time. The BIN file is adopted forstorage. Fault information in the memory can be directly written into the file, and format conversion is not needed. Format conversion is not needed when data are read from the file to the memory, sothat the storage efficiency is improved, and CPU resources are saved. Compared with a text file, the BIN file saves the storage space of the display screen; compared with a database storage mode, theBIN file does not need extra storage space expenditure and CPU resource expenditure for data management. The storage space and CPU resources are further saved.

Description

Technical field [0001] The invention belongs to the technical field of rail transit information display, and in particular relates to a method and system for fault diagnosis, storage and display using a train display screen. Background technique [0002] With the rapid development of modern trains, train drivers and passengers need to obtain a large amount of status information and diagnostic information of the vehicle, which is very important for the safe operation of the train. The train display screen is used to display various status data and diagnostic data during the operation of the train, and the driver interacts with the on-board equipment through the display screen in the driver's cabin. The train fault prompts and early warnings are especially important for the safe operation of the train by the drivers and passengers. The essential. When driving, the drivers and passengers can monitor the key parameters and status of the vehicle system in real time, which is also hel...
