specific Embodiment approach

[0022] Due to the differences in the system time of each BCU, the real-time time of the braking data cannot be accurately located during later data processing, so it is necessary to perform unified GPS time calibration on the data output by each BCU. The purpose of the present invention is to provide an electric locomotive The brake data synchronous dump method and device provide an important time synchronization basis for the brake data of the heavy-duty combined train. The specific implementation methods of the present invention are as follows:

[0023] A method for synchronously dumping braking data of an electric locomotive. The data dumper receives the current braking data from the locomotive BCU through a USB interface, encrypts the data after receiving, and adds the current real-time time stamp for storage. After decryption, the real-time time when the BCU stores the data is calculated according to the real-time timestamp and the system time of the BCU, which is used as ...

Embodiment

[0045] Such as figure 1 As shown, a data dumper for synchronous dumping of brake data of an electric locomotive includes an auxiliary power supply module 1, a GPS module 2, a mini USB interface 3, a 533M ARM chip 4, and a resistive liquid crystal display module 5. Indicator light 6 and power management module 7, described power module 1, GPS module 2, standard USB interface 3, display screen module 5, working state indicator light 6 and power management module 7, USB data receiving encryption module 8, SD card big The capacity memory 9 is all connected to the ARM chip 4. The working principle of the present invention is: receive the current braking data from the locomotive BCU through the mini USB interface 3. After the reception is completed, the ARM chip 4 receives the completed data packet and passes the USB The encryption module encrypts, adds the GPS implementation time stamp provided by the GPS module 2 into the data and stores it, and then transfers it to the host compu...

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...
