A dynamic analysis method for locomotive event data

Abstract

The invention provides a dynamic analysis method for locomotive event data, which is suitable for a locomotive event data recording and processing system, and uses a locomotive description file to store the communication bus type, communication port number, data frame identification code group, variable position, data processing formula, and disposal conditions. and other description information, each description information corresponds to various buses and the data transmission protocol of the bus, the ground equipment reads the description information and transmits it to the on-board equipment, and the on-board equipment creates data frame management classes, data variable management classes, event management classes and After the global management data dictionary, the locomotive event information is extracted, processed and stored. When the data transmission format on the locomotive is updated, modifying the locomotive description file can meet the data analysis requirements without modifying the software, which reduces the testing requirements after the locomotive data is changed, saves costs, and enables the locomotive integration unit and the data recording and processing system. The business boundaries between supply units are clearer, reducing the risk of leakage of locomotive integration units.

Description

technical field [0001] The invention relates to the technical field of locomotive data communication processing, in particular to a dynamic analysis method for locomotive event data. Background technique [0002] In the current locomotive event data acquisition work, first design the locomotive event data acquisition method, write the corresponding embedded software, when the software captures the communication frame where the locomotive event data is located, call a series of corresponding processing functions to complete data extraction, Event discrimination and variable linkage. When changing the locomotive event data settings, such as adding some data or deleting some data at the front of the data frame, the developer needs to repeat the above process, that is, change the embedded software and change the processing function. The amount of engineering is large and the cycle is long. Changing the design requires modifying the program, which will affect other parts of the ...

AI Technical Summary

Problems solved by technology

The amount of engineering is large and the cycle is long. Changing the design requires modifying the program, which will affect other parts of the software, and it is easy to introduce bugs. It is often necessary to start the locomotive to cooperate with the system test. The test is very costly and expensive, and requires professional software development. Personnel are responsible for software modification, and there is a problem of confidentiality of commercial information between the locomotive overall responsible unit and the software development unit
