Locomotive braking data synchronism memory transfer method and data memory transfer machine

Abstract

The invention discloses a locomotive braking data synchronism memory transfer method and a data memory transfer machine. The data memory transfer machine receives present braking data from a locomotive braking control unit (BCU) through a universal serial bus (USB) interface. The data is encrypted after the data memory transfer machine receives the present braking data. A present real-time timestamp is added to store. An upper computer works out real-time time when the BCU stores the data according to the real-time timestamp and system time of the BCU. The real-time time is used as time basis of statistics and analysis in later period. The data memory transfer machine comprises a power supply module, a global position system (GPS) module, a standard USB interface, an advanced RISC machines (ARM) chip, a display screen module, a working state indicator light and a power management module. The locomotive braking data synchronism memory transfer method and the data memory transfer machine has the advantages of being simple and reasonable in hardware circuit, wide in application range and low in cost.

Description

technical field [0001] The invention belongs to the technical field of locomotive braking, and in particular relates to a locomotive braking data dumping method and a data dumper, which are used for synchronously dumping braking data stored in a locomotive braking control unit (hereinafter referred to as BCU), for further data analysis. Background technique [0002] The heavy-duty combined electric locomotive has a long marshalling length and a large traction mass, resulting in a longer braking distance. It is necessary to record the braking data during the entire process of train operation in real time, which is convenient for later data analysis and processing. The electric locomotive braking data is stored in the electric locomotive braking control unit BCU, and the BCU usually regularly collects the electric locomotive braking data for storage for later analysis. [0003] The key point of data separation processing in the later stage is data reliability and real-time pe...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the problem that the time inconsistency of different BCU systems of the existing electric locomotives leads to asynchronous braking data and further leads to inaccurate data analysis results in the later stage, the present invention provides a method and device for synchronous dumping of braking data of electric locomotives. During the process, the data is timed and encrypted to synchronize the braking data
