System for dynamically tracking and monitoring train running based on precise satellite positioning

Abstract

The invention relates to a system for dynamically tracking and monitoring train running based on precise satellite positioning. The invention aims to provide a system for dynamically tracking and monitoring train running based on precise satellite positioning, which is designed for improving the positioning accuracy of train positions, increasing the safe reliability of rail transit scheduling and running, realizing the safety monitoring of train drivers on the whole running area, greatly improving the safety of train running, and minimizing the possibility of train collision and tailgating. The technical scheme of the invention is as follows: a system for dynamically tracking and monitoring train running based on precise satellite positioning is characterized by comprising a vehicle-mounted part and a ground part, wherein the vehicle-mounted part is an adjacent tester arranged on a train head, the ground part is composed of a wide area difference reference station, a local area difference reference station, a difference system data center, a commissioning test machine and an integrated running information module, and the integrated running information module is arranged in a railway administration scheduling system. The system for dynamically tracking and monitoring train running based on precise satellite positioning, disclosed by the invention, is applicable to the monitoring and early warning of trains.

Description

technical field [0001] The invention relates to a train running dynamic tracking and monitoring system based on satellite precise positioning. It is suitable for train monitoring and early warning. Background technique [0002] At present, there are still hidden dangers of major accidents such as head-on collisions and rear-end collisions when railway trains are running. One of the important reasons is that the train driver cannot fully observe the condition of the train on the same track or on the adjacent track. And it is completely up to the dispatcher to give orders, in case of a dispatch error or a malfunction of the signal machine and other devices on the track, the wrong display and wrong signal will cause unimaginable consequences. If a fully visualized train driving target auxiliary driving system is implemented on the railway, so that every train driver can clearly understand the front, rear, left, and right conditions of the train, and the visual environment like...

Problems solved by technology

[0008] According to the description of this patent, the train simultaneously broadcasts the operating parameters of the vehicle to each train, and at the same time receives the broadcast data of the operating parameters of other trains. If the vehicle is equipped with a dual-frequency GPS signal receiver, its design is flawed. Yes: In the specific implementation, it is not mentioned whether the specific equipment used in positioning, processing, and analysis chooses to use differential CORS technology for positioning and correction, and it is still in the stage of conceptual description

[0010] This patent also has a differential system that does not use the CORS reference station, and cannot achieve the minimum required accuracy of orbit identification with an accuracy of less than 2M with a low-cost and high-precision method. Similar to the previous patent, it cannot effectively achieve the purpose of safety monitoring.

[0011] 3. The paper "Railway Electronic Map and Train System Design and Implementation" by Huang Yanqiong et al. Firstly, the high-precision CORS reference station system was not used, and secondly, the comprehensive railway traffic information data in the system lacking the state of the railway track circuit, such as block signals and turnouts The input analysis conditions such as position, which are essential parameters in operation, ensure the real-time business information flow system and GIS electronic map with the status of the track circuit. The method of processing business data can only be realized through the relevant intelligent software system. safe operation, while neither is mentioned in this paper

[0015] The defect of this patent is that the wireless broadcast command is used for communication transmission, but because the railway often passes through tunnels, high mountains, etc., which will hinder the communication of wireless signals, the required communication equipment and other investment are huge, and it also affects reliability

[0016] In this patent, the conventional GPS is used to locate the target, and the CORS differential reference station correction technology is not used, which affects the acquisition of the train's high-precision position
