On-board platform of train operation status information system

Abstract

Provided is a train running state information system vehicle-mounted platform comprising antenna devices for carrying out data transmission with ground equipment. The antenna devices send the received LKJ base data to main control units through wireless communication modules. The main control units are connected with an external interface unit. The external interface unit is connected with a data loading / unloading plug-in. The train running state information system vehicle-mounted platform adopts a dual-redundancy design, that is, the number of the antenna devices, the number of the wireless communication modules and the number of the main control units are two and the antenna devices, the wireless communication modules and the main control units are respectively arranged in parallel. According to the vehicle-mounted platform, the function of carrying out wireless remote reloading on the LKJ base data is realized; the function of carrying out base data file reloading on a plurality of locomotives is realized; whole process management and monitoring of the remote reloading process is realized; automatic control of reloading of the base data is realized; complexity of manual LKJ base data reloading is changed; timeliness, accuracy and controllability of LKJ version reloading work are improved; and informationization level in the aspect of LKJ equipment management is improved.

Description

technical field [0001] The invention relates to a train running state information system (LAIS) platform installed on a train. Background technique [0002] LKJ2000 train operation monitoring and recording device (hereinafter referred to as LKJ), as the main monitoring equipment for domestic locomotives, has been promoted and used throughout the railway, and has played a significant role in ensuring railway transportation safety and promoting locomotive safety management. LKJ adopts the method of on-board storage of line parameters. This storage method requires that on-board data should be maintained and updated with changes in train line facilities, that is, to maintain on-board data storage. Currently, when maintaining system programs and data, it is necessary to To disassemble the device, each data maintenance will cause a lot of waste of manpower and material resources. In recent years, factors such as the construction of new railway lines, the transformation of existin...
