High-speed train approaching warning system and its realization method

Abstract

The invention discloses a high-speed train running approach early warning system, which mainly solves the problems of inaccurate positioning and poor reliability in the prior art, and provides a safety redundant system or a backup system for the driving control of the existing train running control system. The high-speed train approaching early warning system includes a traffic dispatching center; a wireless blocking center, which generates traffic permits based on information provided by ground equipment and interaction with on-board equipment; The turnouts have a restrictive relationship with each other; the GSM-R base station realizes the function of signal transmission between the train and the wireless block center; the track circuit equipment obtains the section occupancy of the train through the positioning of the track circuit; the vehicle-mounted satellite positioning and receiving device is set in On the train, receive satellite positioning signals. By adopting the present invention, when the existing track circuit or the train control system fails, the position of the train can still be accurately determined and the train approaching warning can be carried out to ensure the safety of dispatching.

Description

technical field [0001] The invention relates to an early warning system, in particular to a high-speed train approaching early warning system and its realization method. Background technique [0002] Railway transportation is the most common and extensive mode of transportation in China. With the continuous progress and development of China's railways, the speed of railways is getting faster and faster, and correspondingly, the importance of railway safety is getting higher and higher. Most of the railway accidents in recent years are caused by scheduling and human errors, so the reliability of equipment should be further improved, the automatic safety of equipment should be improved, and the possibility of accidents should be reduced. [0003] On July 23, 2011, a major train rear-end collision occurred in Wenzhou, Zhejiang. According to the analysis of the investigation results, the cause of the accident was that the acquisition equipment of the train control center of Wen...

Problems solved by technology

However, this piece of occupancy information was not collected by the train control center of Wenzhou South Railway Station, so that the 5829 blocked area under the jurisdiction of the Wenzhou South Railway Station train control center and the protection signals of the subsequent two blocked areas displayed green lights by mistake, causing train D301 to drive to train D3115 rear-end collision

[0004] The current train operation control systems CTCS2 and CTCS3 of China Railway use the track circuit to locate the position of the train. Once the track circuit fails, such as the 7.23 Wenzhou bullet train accident, the dispatching command center cannot determine the position and location of the train. Trains are dispatched safely and reliably
