Abstract

The invention discloses a locomotive ground communication transmission method suitable for LKJ vehicle-mounted data remote reloading. The method comprises the steps that vehicle-mounted equipment sends a request registration packet to ground equipment; the ground equipment verifies the verification information in the request registration packet according to a specified rule so as to judge whetherthe vehicle-mounted equipment is allowed to access the network or not; and if the network access is allowed and the locomotive to which the vehicle-mounted equipment accessed to the network belongs has the LKJ vehicle-mounted data remote reloading plan, whether to send a corresponding update package to the vehicle-mounted equipment according to a predetermined mode is determined according to whether the version number of the vehicle-mounted equipment is consistent with the reloading version. According to the method, LKJ vehicle-mounted data remote transmission is achieved by establishing the vehicle-ground communication channel, the working efficiency is improved, and the safety risk of wrong replacement and missing replacement can be avoided.

Description

technical field [0001] The invention relates to the technical field of railway communication, in particular to a locomotive-to-vehicle communication transmission method suitable for remote replacement of LKJ on-board data. Background technique [0002] The current railway locomotives have Dali's train-to-ground communication needs, but they are basically based on the existing 4G or WIFI network. [0003] At present, when changing the LKJ (train operation control recording device) data, it is necessary to run the locomotive to a specific area for inspection in advance, and then use manual operation to change the data, which has the problem of low efficiency, and there are also wrong and missed changes. security risks. [0004] In view of this, it is necessary to develop a new vehicle-to-ground communication transmission method to support the remote replacement of LKJ vehicle data. Contents of the invention [0005] The purpose of the present invention is to provide a loco...
