Train running distance monitoring system and method

Abstract

The invention discloses a train running distance monitoring system and method. The system comprises positioning modules, distance monitoring modules and positioning base stations arranged along a train track, wherein the positioning modules and the distance monitoring modules are arranged on trains. The first train is located in front of the second train, and the two trains adjacently run. The first positioning base station is used for communicating with the positioning module on the first train, obtaining position information of the first train and sending the position information to the second positioning base station. The second positioning base station is used for communicating with the positioning module on the second train, obtaining the position information of the second train, obtaining the distance information of the two trains based on the position information of the two trains and sending the distance information to the distance monitoring module on the second train. The distance monitoring module on the second train is used for comparing the distance information with the preset safety distance threshold value, and if the distance information is lower than the thresholdvalue, an alarm signal is sent out. By means of the train running distance monitoring system and method, the track train running position can be accurately obtained in real time, the running train distance between the trains is monitored, and alarming is conducted when the distance between the front train and the back train is the dangerous distance.

Description

technical field [0001] The present application relates to the technical field of train positioning and distance measurement, and in particular to a system and method for monitoring distance between trains. Background technique [0002] During the operation of the rail train, it is necessary to locate the train in real time and monitor the distance between the front and rear trains so that the front and rear trains maintain a safe distance between them. In the prior art, a wheel axle meter + a wayside radio frequency identification (RFID) transponder or a computer interlocking system (CBI) are used to monitor the position of the vehicle. [0003] Train axle counting technology is widely used in the position measurement of rail trains to calculate the use of the track. The train axle counting technology is susceptible to interference. RFID radio frequency technology can effectively avoid the interference of the external environment and make the train axle counting technology a...

AI Technical Summary

Problems solved by technology

Train axle counting technology and RFID radio frequency identification can not only increase the accuracy of wheel axle counting, but also help the dispatcher to stably identify the running status and identity of each train, which is also of great significance and role in safety, but train axle counting is easy to miss It cannot accurately provide the running position of the train, and thus cannot accurately detect the distance between trains

The computer interlocking system is the core control equipment responsible for the establishment of rail traffic on the road. It can realize interlocking control among the turnouts, signal machines, and track circuits in the station. It is an indispensable guarantee for safe and efficient railway traffic. However, the computer interlocking system is also It cannot accurately provide the real-time running position of the train, nor can it accurately monitor the distance between trains
