Embodiment Construction

[0071] Below, combine figure 1 to introduce the applicable application scenarios of the embodiments of the present application.

[0072] figure 1 It is a schematic diagram of an application scenario of a vehicle communication method provided in an embodiment of the present application. See figure 1 , including vehicle A, vehicle B and vehicle C, and the vehicle includes LTE access network and core network integrated device (WLTBN), terminal equipment (UE) and RFID reader (ED). Among them, LTE access network and core network integrated device (WLTBN), terminal equipment (UE) and RFID reader (ED) constitute the network (CN1) of the train backbone network and the vehicle marshalling network.

[0073] The LTE access network and core network integrated device (WLTBN) is used to realize the signal interaction between the train backbone network and the vehicle formation network, and can be connected to the terminal equipment of different vehicles. For example, see figure 1 , the...

Abstract

The embodiment of the invention provides a vehicle communication method, device and equipment, and the method comprises the steps that a first vehicle obtains a grouping request, the grouping requestis used for requesting the grouping of a plurality of vehicles, and the first vehicle is a vehicle located at an end part in the plurality of vehicles; wherein the first vehicle performs a vehicle discovery operation, after the first vehicle discovers M second vehicles, the first vehicle acquires vehicle information of the M second vehicles, the M second vehicles are other vehicles except the first vehicle in the plurality of vehicles, and M is an integer greater than 1; the first vehicle sends vehicle information of each of the plurality of vehicles to the second vehicle, wherein the vehicleinformation is used for communication of the plurality of vehicles; and the first vehicle determines a host vehicle and activates the WLTBN in the host vehicle, so that the plurality of terminal devices communicate through the WLTBN in the host vehicle. And the vehicle communication efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of rail transit vehicle communication, in particular to a vehicle communication method, device and equipment. Background technique [0002] At present, the passenger flow of rail transit changes greatly (the passenger flow is large during the peak period, and the passenger flow is small during the off-peak period). Therefore, it is necessary to adjust the formation of vehicles (such as trains, etc.) according to the change of passenger flow. [0003] In the prior art, before the vehicles are regrouped, it is necessary to complete the electrical connection between the vehicles to be grouped, so that the vehicles can communicate normally. After the electrical connection is completed, the vehicles in a formation can communicate according to the communication device on the ground. For example, a vehicle sends a signal to a communication device on the ground, and the communication device on the ground ...
