Embodiment Construction

[0055] The above-mentioned features and advantages of the present invention can be better understood after reading the detailed description of the embodiments of the present disclosure in conjunction with the following drawings. In the drawings, components are not necessarily drawn to scale, and components with similar related properties or characteristics may have the same or similar reference numerals.

[0056] Embodiment of the train location detection method based on dynamic adjustment

[0057] In this embodiment, the train location detection based on dynamic adjustment includes initial positioning first, and dynamic adjustment after the initial positioning is completed, and the dynamic adjustment is divided into first performing dynamic distance measurement accuracy calculation, and then calculating the safety package of the train position. network.

[0058] The first is the initial positioning of the train, which means that the train needs to go through the initial po...

Abstract

The invention discloses a method and a system for detecting train positioning on the basis of dynamic adjustment. The technical scheme includes that the method comprises initially positioning trains from non-positioning phases to positioning phases; computing the dynamic distance measurement accuracy whenever the trains are completely initially positioned and then run through every two continuous transponders and effective messages of the transponders are received; computing uncertain values of the locations of the trains on the basis of dynamic distance measurement accuracy computation results and determining safety profiles of the locations of the trains according to the uncertain values of the locations of the trains. The method and the system have the advantages that the train positioning accuracy can be improved to the greatest extent, the arrangement quantity of the trackside transponders can be reduced, and accordingly the engineering cost can be lowered.

Description

technical field [0001] The invention relates to train positioning technology, in particular to a train positioning detection method and system capable of real-time and dynamic adjustment of positioning accuracy. Background technique [0002] The train positioning in the urban rail transit CBTC (Communication Based Train Control, communication-based train control system) system is the key information for realizing continuous train control, and the positioning accuracy directly affects the driving interval (train tracking distance, which refers to the The fixed point measurement is the time interval from the first train A passing through the fixed point to the second train B running in the same direction passing through the same fixed point) and the judgment of train platform stopping. The CBTC system is based on large-capacity, continuous two-way communication of train-ground information and train positioning and control technology to realize train speed control. The continu...
