Method, device and system for establishing communication connection between vehicles

Abstract

The invention provides a method, a device and a system for establishing communication connection between vehicles, the method is applied to a vehicle-mounted controller, the vehicle-mounted controlleris located in the vehicle, and the method comprises the following steps: receiving a vehicle position broadcast packet sent by a target controller; analyzing the vehicle position broadcast packet toobtain the position information of all vehicles in the jurisdiction area of the target controller; determining a target vehicle meeting a communication condition according to the position informationof all vehicles and a preset distance threshold; and establishing a communication link with the target vehicle, and receiving the operation information of the target vehicle through the communicationlink. Therefore, the vehicle-mounted controller obtains the position system information of all the vehicles through the target controller in the current jurisdiction area and selects to establish communication with the vehicles within a certain range, time delay deviation caused by the fact that existing communication connection needs to be disconnected and then communication connection needs to be established again during vehicle route switching is avoided, and the operation efficiency is improved.

Description

technical field

[0001] The invention relates to the technical field of vehicles, in particular to a method, device and system for establishing a communication connection between vehicles. Background technique

[0002] At present, in the fully automatic operation system of related trains, communication connections can be directly established between vehicles through the on-board controller. However, when there is a switch section ahead, there is a possibility that the switch needs to be pulled, for example figure 1 As shown, the current switch is in position, and the communication between car 1 and car 3 has been established. If car 1 needs to take a sideways approach, it is necessary to turn the switch to the reverse position. At this time, car 1 needs to communicate with car 2 in the current switch section in front of it. It must first disconnect the communication connection with car 3, and then establish a communication connection with car 2. The whole process takes a lo...
