Embodiment Construction

[0018] The present invention will be further described below in conjunction with accompanying drawing.

[0019] In the prior art, the driver must first drive the train past two beacons from the time the train departs to the establishment of an operating mode with ATP protection. This distance generally takes a long time, and the driver needs to look out and be responsible for the safety protection of the train. The driver It can only drive at a low speed (20km / h), and the system only provides simple overspeed protection. In order to establish a way of train positioning in a static state, so that in the scene where the on-board equipment is powered on before operation, the positioning can be directly established and enter the fully automatic driving mode or quasi-automatic driving mode, and put into operation without a driver Do anything. The static positioning recovery method after the vehicle-mounted equipment is powered on in the present invention comprises the following st...

Abstract

The invention discloses a static positioning restoration method for on-board equipment after being powered on. The method comprises the following steps: when the respective on-board equipment at bothends of a train is started, trying to obtain respective corresponding sleep and wake-up beacons; when the on-board equipment at both ends of the train reads the corresponding sleep and wake-up beacons, the number of the sleep and wake-up beacons acquired by the other party is mutually checked, and when the numbers are paired with each other, the on-board equipment establishes the positioning of the train with the acquired sleep and wake-up beacons. The invention also discloses a static positioning restoration system for the on-board equipment after being powered on. The static positioning restoration method and system for the on-board equipment after being powered on solve the problem of no positioning in the next morning after the on-board signal equipment is powered off when the train stops at night at the sleep and wake-up points.

Description

technical field [0001] The invention relates to the field of urban rail transit signal systems, in particular to a method and system for restoring static positioning of train on-board equipment. Background technique [0002] At present, after the on-board equipment of the signaling system is powered on, the train does not have positioning information, and the train positioning can only be established after the train runs after the train and continuously reads two trackside beacons. Normally, this positioning establishment process requires manual driving and manual protection by the train driver. In the operation of the CBTC (communicated automatic train control system) system, the positioning of the train is the most basic and crucial information for the establishment of the train mode and the protection of the train interval. [0003] In fully automatic driving or quasi-automatic driving subway lines, trains need to stop at night in the fixed repair section / parking lane, o...
