Problems solved by technology

This method has resulted in an increase in the turn-back interval of the train, which has become a bottleneck restricting the improvement of transport capacity compared to the current urban rail which requires a turn-back interval of two minutes or less.

specific Embodiment

[0069] refer to figure 1 , the scenario we currently assume is: Train A will go up through the switch in the forward direction; then, train B will go down through the switch in the reverse direction. Assuming that the length of the turnout is 70 meters, the speed of the train passing through the turnout in the forward direction is 20 m / s, the time for running one vehicle length (about 130 meters) in the forward direction is 6.5 seconds, and the speed of passing the turnout sideways is 10 m / s. The time to lock and lock is 15 seconds, the time reserved for train B to pass the turnout sideways without decelerating is 12 seconds (less than this time, the train must brake to ensure safety), the moment when train A just occupies the turnout is T0 .

[0070] In the case of using the track section of the turnout as the detection unit for safety protection, the time when car B starts to enter the turnout is T0+37 seconds, that is, the interval between car B and car A using the turnout...

Abstract

The invention relates to a management method for rail transit turnout resources, which comprises: 1) splitting a double-action turnout into a single-action turnout, and subdividing the turnout into: front turnout area, turnout movable area, forward side Defense area, reverse side defense area, forward switch rear area, reverse switch rear area, the train can authorize the switch after passing the switch movable area; 2) Subdivide the allocation status of the subdivision resources of each switch into unallocated , The allocation can be locked and allocated, and it is clearly allocated to which train to use. The use of this turnout resource by the train must be in accordance with the set order; 3) For the same turnout subdivision resource, it can only be allocated to one train at the same time. trains, and the forward side zone and the reverse side zone can only be assigned to the same train at the same time. Compared with the prior art, the present invention has the advantages of making full use of all the resources of the turnout, shortening the passing interval of trains in different directions on the turnout, and the like.

Description

technical field [0001] The invention relates to a signal control technology of urban rail transit, in particular to a management method of rail transit turnout resources. Background technique [0002] Currently, urban rail transit is booming in China, and the CBTC (Communication-Based Train Control) system has become mainstream. In the CBTC system, for the management of switch resources, trains on the same route can be tracked by moving block; trains with different routes must wait for the previous train to clear the track section where the switch is located before the next train can use it. The turnout resource. This method has resulted in an increase in the train turn-back interval, which has become a bottleneck restricting the improvement of transport capacity compared to the current urban rail requirement of two minutes or less. [0003] After retrieval, Chinese Patent Publication No. CN106394611A discloses a switch control method, device and controller, which specific...
