A method for dynamically analyze locomotive event data

Abstract

The invention provides a method for dynamically analyzing locomotive event data suitable for locomotive event data acquisition and processing system, a locomotive description file is use to store thatcommunication bus type, communication port number, data frame identifier group, variable position, data processing formula, description information such as disposal conditions, each description information corresponds to various buses and data transmission protocols of the buses. The ground equipment reads the description information and transmits it to the vehicle-mounted equipment. The vehicle-mounted equipment creates a data frame management class, a data variable management class, an event management class and a global management data dictionary according to the description information, and extracts, processes and stores the locomotive event information. When the data transfer format on the locomotive is updated, Modifying the locomotive description file can meet the needs of data analysis without modifying the software, which reduces the test requirements after the locomotive data change, saves the cost, makes the business boundary between the locomotive integration unit and thedata acquisition and processing system supplier clearer, and reduces the risk of confidentiality leakage of the locomotive integration unit.

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
