Fault diagnosis and display system of urban rail transit vehicle

Abstract

The invention discloses a fault diagnosis and display system of an urban rail transit vehicle. The fault diagnosis and display system comprises a logic processing unit, a fault diagnosis unit, a fault display unit and a database, wherein the logic processing unit is used for receiving data information; when the data information is fault information, fault information to be displayed is determined from the fault information, and the fault information to be displayed and a fault code thereof are sent; the fault information comprises the fault code and fault content; the fault diagnosis unit is used for receiving the fault information to be displayed and storing the fault information to be displayed into the database according to a pre-set rule; and the fault display unit is used for acquiring the fault content of the fault information to be displayed from the database according to the fault code of the fault information to be displayed, and displaying the fault content. According to the fault diagnosis and display system disclosed by the invention, the database corresponding to the fault diagnosis unit and the fault display unit is updated synchronously, so that the database is convenient to operate and maintain, the working amount of workers is reduced, and the manpower sources are saved.

Description

technical field [0001] The invention relates to the technical field of fault diagnosis systems for urban rail transit vehicles, in particular to a fault diagnosis and display system for urban rail transit vehicles. Background technique [0002] The fault diagnosis unit and the fault display unit in the urban rail transit vehicle fault diagnosis and display system in the prior art correspond to a database respectively, and the system stores the fault information in the databases corresponding to the fault diagnosis unit and the fault display unit respectively, and only When the fault code of the fault information is within the preset storage rule range of the fault diagnosis unit, the fault information will be stored in the database corresponding to the fault diagnosis unit; Only when it is within the range will the fault information be stored in the database corresponding to the fault display unit. Therefore, when new fault information appears and the fault code of the faul...

AI Technical Summary

Problems solved by technology

Therefore, when new fault information appears and the fault code of the fault information is not within the preset storage range or not within the preset display range, it is necessary to separately check the preset storage rules in the database corresponding to the fault diagnosis unit and the fault display unit. The preset display rules in the database are updated, but the rules in the two databases cannot be updated at the same time, that is, the two databases cannot be updated synchronously, which makes the operation and maintenance of the database more complicated, and increases the work to a certain extent. The workload of the staff, resulting in a waste of human resources
