Problems solved by technology

That is to say, the reported fault is a false fault, which will not affect the safe operation of the train. However, the occurrence of false faults greatly increases the number of train repair reports, which not only increases the workload of train maintenance, but also reduces the cost of train maintenance. efficiency

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific preferred embodiments, but the protection scope of the present invention is not limited thereby.

[0024] Such as figure 1 As shown, the train fault reporting method of the present embodiment, the steps are: S1. The first device judges whether the subordinate device under its control fails, if so, triggers the fault protection, jumps to step S2, otherwise ends; S2. The first The device triggers the fault protection action and waits for a preset period of time to judge whether the fault still exists. If the fault still exists, it reports the fault to the second device. When the fault does not exist, it does not report the fault.

[0025] In this embodiment, in step S1, the first device judges whether the subordinate device under its control fails. The specific steps are: S1.1. The first device collects the signals of each subordinate device in real time; The ...

Abstract

The invention discloses a train failure report method and a train failure report system. The train failure report method includes the steps of S1, first equipment judging whether subordinate equipment controlled thereby breaks down or not, if yes, triggering failure protection, skipping to the step S2, and if not, terminating; S2, the first equipment triggering failure protection actions and waiting for a preset time period, judging whether the failure exists or not, if yes, reporting the failure to second equipment, and if not, not reporting the failure. The method has the advantages that a large number of fault failures produced in train operation can be shielded, reporting rate of the fault failures is greatly decreased, the number of times of failure reports of a train is reduced, working load in train overhaul is lowered, efficiency in train overhaul is improved and the like.

Description

technical field [0001] The invention relates to the field of train fault handling, in particular to a train fault reporting method and system. Background technique [0002] At present, the fault diagnosis system of subway trains is comprehensively diagnosed and controlled by the microcomputer system according to the variables uploaded by various subsystems or monitored by various sensors, and uploaded through the human-computer interface, and finally repaired by maintenance personnel. The current diagnostic system has high real-time performance, and also delays the signal processing, which can reduce the possibility of false alarm failure. But there is a problem, that is, there is a situation where the fault disappears immediately after being reported. That is to say, the reported fault is a false fault, which will not affect the safe operation of the train. However, the occurrence of false faults greatly increases the number of train repair reports, which not only increase...
