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 capture method and system for train virtual transponders. The method for the train virtual transponder comprises the steps that the running direction of a train is determined, the capture zones of the virtual transponders on a train running rout are determined, and the capture state of the current virtual transponders is judged; if the current virtual transponder is in the capture missing state, the first calculation capture time is calculated according to the train current positioning time and the train running state, and the first calculation capture time is the capture time of the current virtual transponders. According to the capture method and system, the virtual transponder in the capture missing state is recorded, the capture time of the virtual transponder in the capture missing state is reckoned through the train positioning position and the virtual transponders in the capture state, the capture accuracy and the capture probability of the virtual transponders on the train running rout are improved, and it is ensured that the train runs safely and reliably.

Description

technical field [0001] The invention belongs to the field of rail transit, and in particular relates to a method and system for capturing accuracy of a train virtual transponder. Background technique [0002] Transponder equipment is the main positioning equipment in China's train operation control system CTCS-3 / CTCS-4. Combined with the method of using track circuit positioning, it can provide accurate position information of trains and the lines and speed limits required for 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. The use of satellite positioning and positioning technology can greatly reduce the laying density of transponders on the railway track under the premise of ensuring high positioning accuracy, saving eq...
