Embodiment Construction

[0029] Such as figure 2 , image 3 As shown, a method for updating vehicle-mounted data refers to: the PC obtains the basic railway data of train operation, uses the online programmer management software in the PC to convert the format of the basic railway data to obtain a data file, and then writes the data file into in the online programmer. The on-line programmer is a movable device. When in use, the staff takes the on-line programmer to each train and connects the on-line programmer to the monitoring and recording plug-in, so that the data files can be updated to the monitoring and recording plug-in. The above-mentioned monitoring and recording plug-in is located in the train operation monitoring device and replaces the original EPROM device. It receives the transmitted data files and transmits the data files to the train operation monitoring device.

[0030] Such as Figure 4 As shown, the PC is equipped with LKJ online programmer management software. The LKJ online p...

Abstract

Provided is a vehicle data updating method. A PC acquires railway basic data of train operation and converts the form of the railway basic data to obtain a data file, then the data file is written into an on-line programming device, and the on-line programming device updates the data file to a monitoring record plug-in. The monitoring record plug-in is located in a train operation monitoring device, and the monitoring record plug-in receives the sent data file and transmits the data file to the train operation monitoring device. By means of the technical scheme, the monitoring record plug-in is arranged in the train monitoring device, the on-line programming device is adopted to serve as an intermedium to update the vehicle data of a train to the monitoring record plug-in, thus erasure of an EPROM is avoided, and update of the vehicle data can be simply and conveniently achieved.

Description

technical field [0001] The invention relates to a method for updating ground data of a train. Background technique [0002] The train operation monitoring device (LKJ) is an important part of China's train operation control system. It is an important safety equipment for preventing trains from rushing into the signal, running overspeed accidents and assisting locomotive drivers (including EMU drivers) to improve their maneuverability. LKJ vehicle data is the foundation of LKJ control function realization and the basis of operation analysis. The accuracy of LKJ on-board data is the premise and guarantee for monitoring the safe operation of trains. Therefore, there are high requirements for the reliability and security of the LKJ vehicle data update process. [0003] Such as figure 1 As shown, at present, LKJ stores the on-board data in the EPROM of the monitoring record plug-in. When the on-board data changes, the user needs to remove the main processor unit first, and the...
