Vehicle-vehicle communication system based on UWB

Abstract

The invention discloses a vehicle-vehicle communication system based on an UWB. The vehicle-vehicle communication system comprises a main control unit, an information collecting unit, a data storage module, a wireless communication module and a power supply module. The output end of the power supply module is electrically connected with the input end of the main control unit and the input end of the wireless communication module, the main control unit is in bidirectional connection with the wireless communication module and the data storage unit, and the input end of the main control unit is electrically connected with the output end of the information collecting module. The vehicle-vehicle communication system based on the UWB has the advantages of being simple in structure, good in communication effect and the like, communication between vehicles is convenient, and the occurrence possibility of traffic accidents can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a UWB-based vehicle-to-vehicle communication system. Background technique [0002] In the train control system, the on-board equipment has limited processing capacity, completed functions, and intelligence. The train is controlled by ground equipment, and the on-board equipment is only responsible for overspeed protection. It is a passive train operation safety protection method. [0003] During the tracking process of the current and rear vehicles, the position of the front train is collected and processed by the ground equipment, and sent to the rear train in the form of the end point of the driving permit to control the driving interval. Therefore, when the information collected on the ground is wrong or the information is not updated in time and other faults occur , will cause danger. In the existing train control technology, due to the limitations of related technologi...

Problems solved by technology

In the existing train control technology, due to the limitations of related technologies such as train positioning technology, wireless communication technology, and sensor technology, the on-board equipment only establishes communication with the ground equipment that governs the train, and cannot obtain the specific position and working conditions of the train ahead in real time. Status and other information, the processing is simple, the source of information is single and relatively passive, and the ground equipment has too many functions. The increase in the number of equipment has led to the increase of potential safety hazards. The information interaction interface of each system module is becoming more and more complex, and more communication links are likely to affect the reliability of the system
