Data analysis method and apparatus of urban rail signal equipment

Abstract

The invention discloses a data analysis method and apparatus of urban rail signal equipment. The method includes: receiving a to-be-inquired system identifier and a fault keyword corresponding to the system identifier input by a user; obtaining log data of all the urban rail signal equipment in the system in a preset period according to the system identifier; matching the data format of each piece of log data with the data format of a data format dynamic database, and determining the data types of the log data; selecting a network protocol corresponding to the data type according to each data type, and sending the log data of the data type to an analysis module of a simulation MSS server; and analyzing all the log data by the analysis module, and screening fault information corresponding to the fault keyword from the analyzed log data for display. According to the method, the search of problems is facilitated, the fault analysis efficiency is improved, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of signal control, in particular to a data analysis method and device for urban rail signal equipment. Background technique [0002] Urban rail signal equipment is an important factor to ensure the safe transportation of trains, and it is also an important facility to improve the efficiency of train transportation under the premise of safe transportation. In order to ensure the trouble-free operation of urban rail signal equipment, it is very necessary to monitor and maintain the signal equipment through certain measures. [0003] For the failure of the urban rail signal equipment, the on-site staff is usually used to analyze the data recorded in the MSS (Maintenance Support System, Maintenance Support System), and the on-site staff will determine whether it is the fault information sent by the urban rail signal equipment or the urban rail signal equipment. The false alarm information of the rail signal system, and t...

Problems solved by technology

[0004] In practical applications, the analysis process of the above-mentioned urban rail signal equipment failure is very cumbersome, requiring the participation of personnel in various positions, and as the amount of data continues to increase, for software personnel, the difficulty of finding data will also continue to increase. Large, increasing manpower and management costs

[0005] In addition, on-site staff analyze faults on site. On the one hand, they can only manually check the data in MSS, and can only see a single fault, while some faults are caused by multiple errors, and only see a single fault ("cure the symptoms") Sometimes it is impossible to understand the reason behind the fault, and it is necessary to analyze multiple error / fault data before and after to find the real solution to the fault ("permanent cure")

On the other hand, signal equipment manufacturers cannot arrive at the scene every time a fault occurs, which is not only uneconomical, but also unnecessary, and many faults cannot be reproduced at that time
