Example Embodiment

[0035] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0036] See figure 1 with figure 2 Using the automatic analysis method of log data of rail transit vehicle controller based on demand modeling of the present invention to analyze the log data of rail transit vehicle ATP software running for two hours as an example, it specifically includes the following steps:

[0037] Step S101, modeling the ATP software requirements (the ATP software requirements are described in a semi-formal language), which specifically includes the following steps S1 to S4:

[0038] Step S1, load the ATP software requirements document, analyze and filter out 450 requirements described in semi-formal language

[0039] Step S2, perform lexical analysis and grammatical analysis on the 450 requirements selected in step S1

[0040] Step S3, judge the result of the analysis in step S2, if the analysis is passed, the abstract syntax tree is generated...

Abstract

The invention relates to an automatic analysis method for log data of a vehicle-mounted controller based on requirement modeling. The method comprises the steps of S101, conducting modeling to requirements of rail transit vehicle-mounted controller software generating the log data; S102, uploading configuration files needed for log data analysis; S103, uploading the log data; S104, based on a model established in the S101 and a variable mapping table established in the S102, recognizing input and output parameters of the model in the log data, calculating an expectant output parameter according to logical relationship and arithmetic relationship between input and output in the model, and analyzing and comparing the output parameter with a practical output parameter in a log; S105, recording and counting an analysis result and displaying the analysis result intuitively with a graph. Compared with the prior art, the method is capable of automatically analyzing the log data generated by the vehicle-mounted controller software everyday, and the requirements of high efficiency, convenience and intuition are satisfied.

Description

technical field [0001] The invention relates to the field of rail transportation, in particular to a method for automatically analyzing log data of a vehicle controller based on demand modeling. Background technique [0002] In the field of rail transit, the log data of the on-board controller records all the key information of the working status of the on-board controller software (ATP, ATO, etc.), and is an important data source and basis for indoor testing and on-site debugging. Therefore, a large amount of data is generated every day. At present, the analysis method for the log is mainly to manually analyze and check each key variable in each period of data according to the requirement specification. [0003] With the expansion of operating hours and the increase of on-board equipment, the information volume of log data generated every day is likely to increase further. However, the problem with the existing manual inspection is that it usually takes several months to ...
