Problems solved by technology

[0003] In the traditional CBTC system, the safety locking protection of the train running path by the ground interlocking equipment (such as track circuits or axle counting equipment, turnouts, signal machines, etc.) is based on the premise of a fixed route from the signal machine to the signal machine. Setting restrictions will restrict the flexibility of operation and the resource utilization of the entire line; in addition, the on-board equipment of the traditional CBTC system cannot directly obtain the information of the train ahead, and the calculation of the movement authorization needs to be determined after comprehensive processing by the regional controller ZC , the transit time between each subsystem is long, which reduces the response speed of the whole system, affects the train tracking interval, and the line resources cannot be fully and reasonably utilized

Embodiment 1

[0032] Based on the dynamic resource management train operation safety protection system and method, the safety path protection of train operation no longer depends on the fixed route from signal machine to signal machine.

[0033] Train operation safety protection system based on dynamic resource management, including:

[0034] Object controller OC equipment: installed on the trackside, used for line resource recording, trackside basic signal equipment driving and mining control, and providing safety protection when the train is degraded;

[0035] Vehicle-mounted OBC equipment: Provide complete CBTC security protection functions. The vehicle-mounted OBC applies to the object controller OC for moving route locking in real time according to the train operation plan. The object controller OC controls basic signal equipment such as trackside switches and signal machines to provide train operation Reserve a safe path, dynamically obtain the usage of line resources from the object ...

Embodiment 2

[0038] combine figure 1 As shown, the entire protection process of the train operation safety protection method based on dynamic resource management is described as follows:

[0039] In order to better illustrate this inventive method, the following explanations of terms are first agreed:

[0040] Resources: Line usage rights required for train operation;

[0041] Reserved: that is, locked. If the resource is reserved, the direction cannot be changed. If the turnout is reserved, the turnout cannot be operated;

[0042] Unreserve: release of locked resources;

[0043] Step 1: Assuming that there are two vehicles on the line, the front vehicle and the rear vehicle, and the P1-P3 turnout is positioned, the front vehicle determines that its driving intention is to run from the current position to S04 according to its own train operation plan; the rear vehicle determines according to its own train operation plan. The operation plan determines that its driving intention is to run...

Abstract

The invention discloses a train operation safety protection system and method based on dynamic resource management, including: object controller OC equipment: set on the side of the track, used for line resource recording, trackside basic signal equipment driving and mining control, and providing train degradation Vehicle-mounted OBC equipment: provide complete CBTC security protection functions; through mutual communication between vehicle-mounted equipment OBCs, the vehicle-mounted equipment OBC obtains its position and speed information from the front vehicle OBC, and combines the track information obtained from the object controller OC. On the premise that a safe path has been reserved for the train, according to the use of line resources and the type of obstacles, the mobile block principle is used to independently calculate the movement authorization, and calculate the continuous train target distance mode for the safe operation of the train. Curve, real-time monitoring and protection of the safe operation of the train. The present invention no longer depends on the fixed route from the signal machine to the signal machine, and realizes the dynamic allocation and unified management of resources through the cooperation between the OBC and the OC.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to train operation safety protection technology. Background technique [0002] At present, the relatively advanced and mature urban rail transit signaling systems are all traditional CBTC systems. This system adopts the control structure with ground equipment as the core. The ground interlocking equipment controls ground switches, screen doors, signal machines, etc.; the ground area controller ( ZC) Through the ground track equipment status (track circuit or axle counting equipment, turnout, signal machine, etc.) and the position information reported by the train, a movement authorization is formed and sent to all trains in the area, and sent to the on-board equipment through vehicle-ground communication, Then, the on-board equipment calculates the train target distance mode curve according to the driving permit to monitor the train operation in real time to prevent the train f...
