Embodiment Construction

[0037] The present invention does not make any changes to the network topology and equipment of the original car, but only adds a network cable to the reserved interface of the original Ethernet switch, and connects an external notebook to download data, such as figure 2 shown.

[0038] According to the original vehicle network communication principle, except for the driver display 1 (DDU1), when other display screens enter the event and fault interface, all event and fault information will be forwarded on the Ethernet. Use the Ethernet packet capture tool for data capture analysis.

[0039] After careful analysis and repeated testing, the specified data storage format is as follows:

[0040] 1) The data is stored in text format;

[0041] 2) Record types include events, faults without detailed data and faults with detailed data;

[0042] 3) Events and fault records without detailed data occupy one line, and faults with detailed data occupy multiple lines. The data storage ...

Abstract

The invention belongs to the field of the locomotive control system, and relates to an event and fault record of the locomotive, specifically a novel internal combustion locomotive event and fault data downloading method. Nothing of network topology and equipment of an original locomotive cannot be changed, only a cable is added in a reserved interface of an original ethernet switch to externallyconnect with a computer, an Ethernet packet sniffer tool in the computer is used for performing data packet sniffer analysis on the data forwarded by an Ethernet switch to obtain packet sniffer data;the packet sniffer data is set as method protocol data of the displayed content of a driver display screen after being repeatedly compared and tested with the displayed content of the driver display screen; and the set method protocol data is stored and analytically displayed on the computer. Under the condition of not adding any hardware cost, the problems of harmony 3-type internal combustion locomotive event and fault data downloading difficulty and inconvenient data reading are solved.

Description

technical field [0001] The invention belongs to the field of locomotive control systems, relates to event and fault records of locomotives, in particular to a novel method for downloading event and fault data of internal combustion locomotives. Background technique [0002] The event and fault record is an essential function of the locomotive control system, which is of great significance to the safe operation, maintenance and so on of the locomotive. The event and fault records of the locomotive can be viewed on-site through the driver's display screen, or downloaded through the interface provided by the locomotive control system and viewed offline. [0003] The "Harmony" 3 diesel locomotive is a freight locomotive with the world's advanced level. The whole vehicle is designed with double cabs, and each cab is equipped with two driver display screens (DDU). Its network topology is as figure 1 Shown: [0004] The locomotive event and fault storage download process is as ...
