Automatic selection method of multi-protection sections based on ats timetable operation management

Abstract

The invention discloses a multi-protection-section automatic selection method based on ATS schedule operation management. The multi-protection-section automatic selection method comprises the steps that when a train travels to the direction of protection sections, the trackside ATP applies for protection section direction information to an ATS after judging whether turnouts exist on the protectionsections or not; after receiving the protection section direction application information, the ATS returns direction information of protection sections needing to be locked to the trackside ATP according to an operation plan and the operation destination of the train; then the trackside ATP judges whether establishing of the protection sections needs to be applied to a CBI according to the direction information of the protection sections needing to be locked, protection section occupied information, and information that whether the protection section expected turnout position is consistent tothe actual position, wherein all the information is obtained from the ATS; and the protection section consistent to the train operation direction is finally selected and established through effectivecooperation of the ATS, the trackside ATP and the CBI. According to the multi-protection-section automatic selection method based on ATS schedule operation management, the expected direction of the multiple protection sections is selected through the mode of ATS schedule operation management, and operation of the train no longer relies too much on the protection section direction information selected by the CBI.

Description

Technical field [0001] The invention relates to rail transit technology, in particular to an urban rail transit signal system. Background technique [0002] In the urban rail transit signal system, in order to ensure that trains can stop efficiently and safely in areas that require precise stopping, such as platforms and turn-back tracks, a block section needs to be extended. We call this block section a protection section. If there is a turnout in the protection zone and the required safety protection distance (the safety distance from the predetermined parking position to the restriction point when the parking safety control is implemented) has been extended to the point of the turnout, the turnout needs to be included in the protection zone of the protection zone. According to actual operational needs, this switch can be set as a priority or critical OVERLAP. During the operation of the train, the direction setting of the protection section that has a switch and needs to be p...

Problems solved by technology

by figure 1 As an example, suppose that according to the operation plan, the previous car is going to the direction of S03 via S02, and the destination of this train is going to the direction of S05 via S02. Under the tight tracking operation, the current car is passing the switch P01 -P03 reverse position, ATS has not established the route from S02 to S05 for the following train, then according to the priority established in the protection zone, CBI will establish the protection zone of P01-P03 in reverse position for this train and send it to the track The side ATP is used to calculate the movement authorization. At this time, the route from S02 to S05 cannot be established because the turnout P01-P03 is locked in the reverse position by the CBI protection. Only when the train stops at T1103, the on-board ATP no longer needs the protection section The protection zone can only be unlocked when the lock information is locked, and the lock of the turnout P01-P03 will be released. When the lock of the turnout P01-P03 is released, it is possible to establish the route of S02-S05, which will seriously affect the operation efficiency.
