Effectiveness Verification of Train Real-time Positioning Function Based on Speed Measuring Radar and Electronic Map under TACS
Journal Title: Urban Mass Transit - Year 2024, Vol 27, Issue 9
Abstract
Objective At present, CBTC (communication based train control) precise train positioning technology is prone to high cost of engineering construction and reconstruction, positioning errors and etc. Therefore, it is necessary to upgrade the existing train positioning method. Method The current commonly used technologies for train positioning are described. Based on the feature that the train is equipped with radar protection devices under TACS (train autonomous control system), a train mileage algorithm based on radar speed measuring integral is proposed. The principle of train autonomous positioning based on mileage mark is introduced. On this basis, a train real-time positioning function based on "speed measuring radar and electronic map" under TACS is put forward, and a real-time positioning method with radar speed measuring matching the electronic map is established. The above system is verified by the simulation platform. Result & Conclusion Simulation tests verify the effectiveness of the train real-time positioning function based on "speed measuring radar and electronic map" under TACS.
