Train Approaching Intelligent Early Warning System and Its Early Warning Method

Abstract

The invention discloses an intelligent early warning system for the closing of a train and an early warning method of the intelligent early warning system. The intelligent early warning system comprises an early warning server. The early warning method comprises the following steps: receiving train position information transmitted by vehicle-mounted equipment through a public wireless network by the early warning server; transmitting early warning information of the closing of the train to a path opening terminal through the public wireless network by the early warning server, and besides receiving path opening position information collected by the path opening terminal; also transmitting the early warning information of the closing of the train to mobile equipment of working personnel through the public wireless network by the early warning server, and besides receiving position information collected by the working personnel or an operation point. The early warning server is arranged in a machine room and connected with accession equipment of the public wireless network through optical fibers and twisted-pair lines. The intelligent early warning system and the early warning method, which are disclosed by the invention, have the benefits of being suitable for a line zone with automatic blocking and an in-station accouterment monitoring system and being also suitable for full-automatic intelligent early warning system for the closing of the train in a non-automatic blocking zone.

Description

technical field [0001] The invention relates to an intelligent train approach early warning system and an early warning method thereof. Background technique [0002] There are following problems in prior art: [0003] 1. Low efficiency: The existing technology mainly uses wireless walkie-talkies to release train approach information. This protection method has obvious disadvantages: wireless walkie-talkies have communication distance limitations; wireless walkie-talkies have low scheduling efficiency; [0004] 2. High work intensity: As the density and speed of passing vehicles continue to increase, the work pressure and mental pressure of safety protection personnel will increase accordingly, which will easily lead to major casualties and property losses due to work omissions; [0005] 3. The scope of application is narrow: the existing train approach early warning system is developed for the line with automatic block and monitoring system in the station. The early warning...

AI Technical Summary

Problems solved by technology

[0003] 1. Low efficiency: The existing technology mainly uses wireless walkie-talkies to release train approach information. This protection method has obvious disadvantages: wireless walkie-talkies have communication distance limitations; wireless walkie-talkies have low scheduling efficiency;

[0004] 2. High work intensity: As the density and speed of passing vehicles continue to increase, the work pressure and mental pressure of safety protection personnel will increase accordingly, which will easily lead to major casualties and property losses due to work omissions;

[0005] 3. The scope of application is narrow: the existing train approach early warning system is developed for the line with automatic block and monitoring system in the station. The early warning system obtains train operation information from the monitoring system and collects it with other geographical location information collection equipment The GPS information is calculated and the train approaching warning information is issued

In the non-automatic block section, the early warning system cannot obtain train operation information, and cannot meet the requirements of train approaching early warning.

[0006] 4. Disturbance: the existing crossing terminal does not have the function of automatic volume switching control, which may easily cause disturbance at night;

[0007] 5. The existing train approach detection communication equipment often does not have the function of network status detection. If the mobile device and the crossing terminal have been disconnected from the network, it is easy to cause the information blank time period when the train cannot obtain real-time information, which will inevitably pose a threat to the safety of the train.
