Embodiment 1

[0039] refer to figure 1 , the present embodiment discloses a wireless communication system for micro-rail vehicle control, the system divides the track line into a plurality of sections through the positioning mark 6, and a trackside communication unit 1 is installed at the center of each section, and the track The reliable communication range covered by the side communication unit 1 is the communication section. Each communication section is configured with a communication channel. The communication channels in adjacent communication sections are different. The trackside communication units 1 are connected through the field bus 3. Unit 2, the on-board communication unit 2 establishes a connection with the trackside communication unit 1 by switching communication channels, the trackside communication unit 1 assigns a communication address to the on-board communication unit 2, and exchanges data with the on-board communication unit 2 in time-sharing in turn, realizing trackside...

Embodiment 2

[0054] A wireless communication method for micro-track vehicle control, the method is:

[0055] The starting position identification device on the vehicle identifies the starting position, determines the communication zone where the current vehicle is located, and switches the communication channel of the vehicle-mounted communication unit 2 to the same communication channel as the communication zone;

[0056] During the movement of the vehicle, the positioning mark 6 is recognized by the positioning identification device 7, and the vehicle enters a different communication interval, and the communication channel of the vehicle communication unit 2 is adjusted;

[0057] The wayside communication unit 1 assigns communication addresses to multiple vehicles in the communication interval, the wayside communication unit 1 actively initiates communication, the addressed vehicle responds, and the remaining vehicles remain silent until the wayside communication unit 1 communicates with ...

Abstract

The invention discloses a wireless communication system and method for micro-rail vehicle control, and the system enables a rail line to be divided into a plurality of sections through a positioning mark, a trackside communication unit is installed at the central position of each section, the reliable communication range covered by the trackside communication units is a communication section, andeach communication section is provided with a communication channel. The communication channels of the adjacent communication sections are different, the trackside communication units are connected through a field bus, a vehicle-mounted communication unit is installed on the carriage, the vehicle-mounted communication unit establishes connection with the trackside communication units by switchingthe communication channels, and the trackside communication units allocate communication addresses to the vehicle-mounted communication unit. And the trackside communication units exchange data with the vehicle-mounted communication unit in turn in a time-sharing manner to realize information interaction between the trackside communication unit and the vehicle-mounted communication unit. The problems that existing micro-rail vehicle communication is prone to interference, and real-time performance and safety cannot be guaranteed are solved.

Description

technical field [0001] The invention relates to the technical field of rail vehicle communication, in particular to a wireless communication system and method for micro-rail vehicle control. Background technique [0002] Personal rapid transit can be realized with a suspended wheel-rail vehicle with a track width of less than 600mm, which is called a micro-rail system here. Reliable real-time communication between vehicles and trackside equipment in the micro-rail system is an important means for micro-rail vehicle control and automatic driving. [0003] Most of the existing communication schemes use open space wireless communication equipment to exchange data with the control center for central control and scheduling. The problem is that the communication distance is limited, and the communication is easily affected and interfered by the environment; multiple vehicles communicate with each other at the same time. Dispatch monitoring center communication will produce commun...
