Problems solved by technology

However, in some special scenarios where the satellite signal is blocked by buildings, mountains, etc., the train cannot receive the satellite signal, causing the train to miss the virtual transponder
In the prior art, after the train misses the virtual transponder, it continues to move forward without any operation on the missing state, resulting in blurred train driving records, and it is impossible to know the train’s driving history

Abstract

The invention relates to a method and system for capturing a virtual transponder of a train, wherein the method for capturing a virtual transponder of a train comprises: determining the driving direction of the train, determining the capturing area of ​​the virtual transponder on the driving route, and judging the capturing state of the current virtual transponder ; If the current virtual transponder is in the missed capture state, then calculate the first calculation capture time according to the current train positioning time and the train running state, and the first calculation capture time is the capture time of the current virtual transponder. The invention realizes the recording of the virtual transponder in the state of missed capture, and calculates the capture time of the virtual transponder of missed capture through the positioning position of the train and the virtual transponder in the captured state, so as to improve the accuracy and probability of capture of the virtual transponder on the driving route , to ensure the safe and reliable operation of trains.

Description

technical field [0001] The invention belongs to the field of rail traffic, and in particular relates to a method and a system for capturing accuracy of a train virtual transponder. Background technique [0002] The transponder equipment is the main positioning equipment in China's train operation control system CTCS-3 / CTCS-4. Combined with the method of using the track circuit positioning, it can provide the accurate position information of the train and the line and speed limit required for the train operation. Information is an important guarantee to ensure the safe and reliable operation of trains. With the development of satellite positioning technology, the use of satellite positioning can provide real-time high-precision train positioning, and it is gradually applied in the railway field. Using satellite positioning and positioning technology can greatly reduce the laying density of transponders on railway tracks under the premise of ensuring high positioning accuracy...
