Abstract

The invention discloses a locomotive-to-ground communication transmission method suitable for remote replacement of LKJ vehicle-mounted data, including: the vehicle-mounted equipment sends a request registration package to the ground equipment; Determine whether to allow on-board equipment to access the network; if the network is allowed, and the locomotive to which the on-board equipment belongs has a LKJ on-board data remote replacement plan, then decide whether to send the on-board equipment according to the predetermined method according to whether the version number of the on-board equipment is consistent with the replacement version. Send the corresponding update package. The above method realizes the remote transmission of LKJ vehicle data by establishing a vehicle-ground communication channel, which not only improves work efficiency, but also avoids the safety risks of wrong and missed replacements.

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...
