Abstract

The invention relates to a train position envelope calculation method, a train position envelope calculation device and a train position envelope calculation system for moving block. Respectively determining a maximum safety front end, a minimum safety front end, a maximum safety rear end and a search direction and a search length of the minimum safety rear end relative to the transponder according to the distance from the train estimation front end to the transponder and the train positioning error; a maximum safe front end position, a minimum safe front end position, a maximum safe back end position and a minimum safe back end position are thus determined. According to the method, the specific position of the train can be positioned by the ground equipment under the condition that the vehicle-mounted equipment does not carry an electronic map, so that the running permission can be calculated for the train, the multi-train tight tracking can be realized, conditions are created for realizing the moving block, and the operation efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of railway train control, and in particular relates to a method, device and system for calculating a train position envelope for mobile blockage. Background technique [0002] In the high-speed train control system and the urban rail train control system, the accurate and fast calculation of the train position envelope is an important issue that affects the safety and efficiency of driving, especially in the throat area. By calculating the train position envelope, the precise positioning of the train can be obtained. Based on this, the block partitions that move synchronously with the train can be dynamically calculated, thereby shortening the train tracking interval. This process is the basic condition for realizing mobile blockage. [0003] In the CTCS-3 train control system, the on-board equipment ATP carries an electronic map, and sends the transponder number and relative offset to the ground equipment R...
