Abstract

The embodiment of the invention provides a signal equipment fault diagnosis method and fault diagnosis system, and belongs to the technical field of rail traffic. The diagnosis method comprises the steps that railway operation data is acquired in real time; simulation calculation is conducted according to the railway operation data and an interlocking table; and the signal equipment fault reason is determined according to a result of simulation calculation and the acquired railway operation data. According to the technical scheme, the signal equipment fault reason can be quickly and accuratelydetermined, the working efficiency is improved, and the interference to railway transportation by faulty signal equipment is reduced.

Description

technical field

[0001] The invention relates to the technical field of rail transit, in particular to a signal equipment fault diagnosis method and a diagnosis system. Background technique

[0002] In the prior art, the computer monitors the data related to train operation, and manually analyzes the data and the generated curves one by one to identify pathological data, thereby achieving the purpose of preventing or solving the failure of signal equipment. However, the amount of data obtained through computer monitoring is very large, which makes manual analysis of monitoring data labor-intensive and poor in timeliness. Moreover, the analysis quality of this analysis method also varies from person to person. For example, in terms of capturing instantaneous changes, data correlation analysis, and comparative analysis of historical data, manual analysis is incompetent. Contents of the invention
