Abstract

The invention discloses a data processing method and device for a locomotive. The method comprises the steps of obtaining message event data on an FIP bus of a locomotive; matching the event code with a constant fault code of the locomotive; and analyzing the message event data hit by code matching, and storing an analysis result as an event record process file. According to the embodiment of the invention, message event data on FIP bus are obtained, event codes in message event data are matched with constant fault codes, and message event data are screened, analyzed and packaged and stored as event recording process files. The locomotive quality is comprehensively monitored, and the problem of time delay in data transmission and data analysis caused by overlarge data volume is solved. Therefore, the data analysis and processing time after entering the station is saved, the stop time of the locomotive is reduced, real-time analysis and early warning on the way can be realized, and the fault state can be predicted in advance.

Description

technical field [0001] The present application relates to the technical field of locomotive information processing, in particular to a method and device for data processing of locomotives. Background technique [0002] The existing locomotive data train inspection method is based on the message record file (ie *.TXT file) displayed in the driver display unit (DDU) for data analysis. Usually only when the locomotive returns to the depot, the data analysts can get on the locomotive, download the corresponding event record file through the USB interface on the DDU, and then use the ground analysis software to locate the locomotive after it has been screened, analyzed, and processed. past fault and event record information. In addition, the event record file in the prior art only records the event information of the fault point, but does not record the operating status of the locomotive and the key data information when the fault occurs. Locomotive quality monitoring. Conten...
