Problems solved by technology

[0002] The automatic train monitoring system and the interlocking system need to use a large amount of station static data. With the development of technology, the amount of data required is also increasing. Automation technology has also been applied to the station data generation process, but the increase in the amount of data and the The inconsistency of the line also increases the probability of data errors
In particular, the formulas and route interlocking tables in the station data have the characteristics of large data volume and complex logic, and manual troubleshooting becomes more and more difficult. Therefore, a method is urgently needed to verify the integrity and validity of the station data

Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings.

[0013] like figure 1 As shown, the whole verification method can be divided into three layers: data layer, verification layer and result layer. In the data layer, based on the signal layout diagram, use data modeling tools to generate station data, including directed graph models, topology models, route interlocking tables and route formulas, etc.; in the verification layer, based on scripting language Write the corresponding rule base of the station data model and import the station data generated by the data modeling tool into the data verification tool to perform verification; at the result layer, generate a grammar check report, validity report and graphic verification report, and then the verification report will be Feedback to the data modeling tool again to modify the station data model; repeat the above steps until the data in the data verification report is c...

Abstract

The invention discloses an urban rail traffic station data validation method which comprises the following steps of: (1) creating station data models by using a data modeling tool according to the station data model design principle; (2) compiling rule bases corresponding to the station data models by using scripting language according to the characteristics of the station data models and loading the station data models into a station data model validation tool; (3) selecting corresponding rules for the different models and validating the station data so as to generate a validation report; and (4) performing iterative validation on the data according to the validation report until the data is completely accurate. According to the whole method, the data is validated more strictly and efficiently from the syntax to the semantics, so that the data validity is effectively ensured; the working efficiency is improved; and the working progress is accelerated. Thus, the usability, the security and the reliability of the system data level are ensured.

Description

technical field [0001] The invention belongs to the field of urban rail transit, and mainly relates to a data verification method for urban rail transit stations. Background technique [0002] The automatic train monitoring system and the interlocking system need to use a large amount of station static data. With the development of technology, the amount of data required is also increasing. Automation technology has also been applied to the station data generation process, but the increase in the amount of data and the The inconsistency of the line also increases the probability of data errors. In particular, the formulas and route interlocking tables in the station data have the characteristics of large data volume and complex logic, and manual troubleshooting becomes more and more difficult. Therefore, a method is urgently needed to verify the integrity and validity of the station data. Contents of the invention [0003] Purpose of the invention: the purpose of the pres...
