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-boa

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, and the system comprises object controller OC equipment which is disposed beside a rail and is used for recording line resources, carrying out the drive and collection control of trackside basic signal equipment, and providing the safety protection during the degradation of a train;vehicle-mounted OBC equipment which is used for providing a complete CBTC safety protection function; through mutual communication between OBCs, the OBC acquires the position and speed information ofthe OBC from the front OBC; by combining the trackside equipment state information acquired from the object controller OC, on the premise that a safe path is reserved for a train, according to the usecondition of line resources and the type of obstacles, movement authorization calculation is conducted autonomously according to the movement blocking principle, a continuous train target distance mode curve is calculated for safe operation of the train, and safe operation of the train is monitored and protected in real time. The method does not depend on a fixed route mode from the annunciator to the annunciator any more, and dynamic allocation and unified management of resources are achieved through 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...
