Train block partition calculation occupation method and system based on satellite positioning

Abstract

The invention discloses a train block partition calculation occupation method and system based on satellite positioning, and the method comprises the following steps: S1, calculating the real-time speed and position of a train, and combining the position of a train antenna and the length of the train according to the real-time speed and position of the train, obtaining the positions of the worst front end WCA of the train, the worst rear end WCB of the train and the worst locomotive tail WCLP of the train; S2, according to the integrity state of the train and the positions of the WCA, the WCB and the WCLP, obtaining corresponding block partition occupation information in combination with electronic map information; and S3, after the WCB enters a new block partition, inquiring the train tail state, if it is inquired that the train tail pipe pressure is high, sending a corresponding block partition clearing message by a vehicle-mounted computer to the radio block center, if it is inquired that the train tail pipe pressure is low, reporting that the train integrity is lost by the the vehicle-mounted computer to the radio block center RBC, and performing LOI blocking on the corresponding block partition by the radio block center.

Description

technical field [0001] The invention relates to train signal control, in particular to a method and system for calculating occupancy of train block zones based on satellite positioning. Background technique [0002] In the existing CTCS signaling system, the track circuit is used to detect the occupancy and clearance of trains in the block section. In the case that the blocked area is normally occupied by the train, the ground equipment will automatically set the movement authorization to ensure driving safety. When the train does not enter the blocked area, but the track circuit is abnormally occupied, the ground equipment will also block the corresponding section, resulting in a decrease in the operating efficiency of the line; when the track circuit is not well shunted, even if the train enters the blocked area, the occupancy cannot be detected Information that endangers driving safety [0003] The train control system operating on the Qinghai-Tibet Line cancels tracksi...
