Train management system

Abstract

The invention discloses a train management system. The train management system comprises vehicle-mounted equipment, an aerostat, a base station, a satellite and a dispatching center, wherein the vehicle-mounted equipment is used for acquiring train data information, establishing a communication connection with one of three types communication equipment of a aerostat, a base station and a satelliteaccording to the priority from high to low, and sending train data information to communication equipment for establishing communication connection; the aerostat, the base station and the satellite are used for receiving train data information and sending the train data information to the dispatching center; and the dispatching center is used for receiving the train data information and sending the train management information to the communication equipment for establishing communication connection according to the train data information, so that the communication equipment which is in communication connection can send the train management information to the vehicle-mounted equipment. The system comprises three types of communication equipment, namely the aerostat, the base station and the satellite, the vehicle-mounted equipment is preferentially connected with the high-priority communication equipment to transmit train data information, so that the information transmission stabilityis improved, and the safety of the train is guaranteed.

Description

technical field [0001] The present application relates to the technical field of rail transit, in particular to a train management system. Background technique [0002] With the development of science and technology, the control and management methods of trains have gradually changed, and the integrated vehicle networking system based on air, sky, vehicle and ground is used to manage trains to deal with emergencies. [0003] In the prior art, when using the air-space-vehicle-ground integrated vehicle networking system to manage the train, the speed information and location information of the train are collected, and then communicated through a separate base station or a separate satellite. The communication method is single, and the base station signal is not Stable, greatly affected by the line, prone to breakpoints, limited satellite bandwidth, unable to transmit a large amount of train data information, resulting in poor stability of the entire Internet of Vehicles system...

Problems solved by technology

[0003] In the prior art, when using the air-space-vehicle-ground integrated vehicle networking system to manage the train, the speed information and location information of the train are collected, and then communicated through a separate base station or a separate satellite. The communication method is single, and the base station signal is not Stable, greatly affected by the line, prone to breakpoints, limited satellite bandwidth, unable to transmit a large amount of train data information, resulting in poor stability of the entire Internet of Vehicles system, which makes the speed information and position information of the train unable to be transmitted , the safety of trains cannot be effectively guaranteed
