Train operation safety protection system and method based on dynamic resource management

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...

AI Technical Summary

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
