Temporary speed limit processing system and method for uncontrolled trains

Abstract

The invention discloses a temporary-speed-limitation processing system and method of an uncontrolled train. The temporary-speed-limitation processing system comprises an automatic train supervising system, an area controller and signal machines, wherein the area controller receives an access request sent from the automatic train supervising system and authorizes access for the uncontrolled train; the area controller judges the temporary-speed-limitation state of each corresponding signal machine; when the temporary-speed-limitation state of each signal machine is information representing that the axle counting section corresponding to the signal machine has the temporary-speed-limitation requirement, the signal machine is controlled to display a no-passing signal, or the signal machine is controlled to display a passing signal; when the signal machine positioned at the downstream side of the traveling direction of the uncontrolled train and closest to the uncontrolled train, the uncontrolled train sends the temporary-speed-limitation requirement to obtain a first temporary-speed-limitation value, and travels at a speed lower than the first temporary-speed-limitation value. The temporary-speed-limitation processing system and method disclosed by the invention have the advantages that temporary speed limitation can be executed by the uncontrolled train, so that safe traveling at the speed-limitation section is protected.

Description

technical field [0001] The invention relates to the field of automatic train protection applied to urban rail transit signal systems, in particular to a temporary speed limit processing system for uncontrolled trains and a temporary speed limit processing method realized by the temporary speed limit processing system. Background technique [0002] A controlled train refers to a train that can communicate with the trackside mobile authorization unit wirelessly, and runs in ATO mode (train automatic operation mode, which means that the system is responsible for driving the train and ensures that it runs automatically under the protection of the train's automatic protection function) or ATPM mode (train automatic protection manual driving mode, which means that the driver is responsible for driving the train, and the system ensures the complete protection of the train automatic protection function); while the train running in other cases mainly refers to the train running in RM ...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to overcome the inability of the uncontrolled trains in the prior art to obtain temporary speed limit information when they lose communication with the mobile authorization unit, and thus cannot ensure that all line sections requiring temporary speed limit can be obtained. Effective protection leads to the defect of potential safety hazards, providing a temporary speed limit processing system and method for uncontrolled trains, which can still obtain temporary speed limit information when the train is not under control, thereby ensuring that temporary speed limits are required Line sections can be effectively protected, reducing potential safety hazards
