Abstract

The invention discloses a train speed limit control method and management system for rail transit. The train speed limit control method for the rail transit comprises the following steps that completevehicle state information and speed limit mode data of trains are collected and analyzed, and whether a triggering condition of train speed limit control are met or not is judged by utilizing a preset fault speed limit list; when the triggering conditions is met, a fault speed limit value corresponding to the fault severity level and a mode speed limit value under the speed limit mode data are determined according to the fault information and the fault speed limit list, and when a plurality of triggering conditions are met, a lowest speed limit value is taken as a train speed limit target value; according to the train speed limit target value, speed limit information is fed back, and / or a train protection mechanism including traction blockade and emergency braking is started to realize the speed limit control of the trains. The speed can be comprehensively and reliably controlled, the running safety of the trains is ensured, the train speed limit control method and management system for the rail transit can be flexibly arranged according to different items, and the multi-level train protection mechanism is achieved, so that the speed limit management is more reliable.

Description

technical field [0001] The invention relates to the field of train control, in particular to a train speed limit control method and management system for rail traffic. Background technique [0002] During the operation of rail transit trains, the reliability of its traction system and braking system is extremely important. If a fault occurs during driving, the relevant faulty unit must be removed to ensure that the fault does not expand as much as possible and maintain the train operation. In addition, according to the requirements of the project, in other situations, the train needs to enter specific scenarios such as coupling and car washing. In this scenario, on the one hand, the train is required to run at a low speed, and the train is also required to be switched relative to the traction state. Therefore, for The control and management of driving speed is particularly important. [0003] Generally, the control of the train speed is carried out by relying on the tradit...
