Method and system for column control temporary speed limit

Abstract

The invention discloses a method and a system for column control temporary speed limit. The method includes the following steps: a dispatching center receives a temporary speed limit command input by a dispatcher and sends the temporary speed limit command to a temporary speed limit server, wherein the temporary speed limit command comprises a speed limit line, a speed limit value and a speed limit range; the temporary speed limit server verifies the received temporary speed limit command and confirms whether the temporary speed limit command is legal or not; the dispatching center receives an executive command of the dispatcher and sends the temporary speed limit command verified to be legal to the temporary speed limit server to be executed. According to the technical scheme, the column control temporary speed limit command can be issued, and accuracy and reliability of issuance of the temporary speed limit command are improved.

Description

Technical field [0001] The invention relates to a train speed limit control technology, in particular to a train control temporary speed limit control method and system. Background technique [0002] The railway speed limit is an important measure to ensure the safety of the train during the running of the train. In the actual operation of the train, the train is often controlled temporarily according to the needs. Therefore, how to effectively issue the speed limit command underground is to ensure the safety of the train. An important factor in operation. [0003] At present, the temporary speed limit of train control is generally manual, that is, the temporary speed limit command is issued to each station in the form of a file, and each station controls the trains running on the speed limit line according to the temporary speed limit command. Ensure that the trains on the speed limit line are running at the speed limit value. For example, when a temporary speed limit is required...

AI Technical Summary

Problems solved by technology

[0004] However, in the existing train control temporary speed limit control method, it is not conducive to centralized management of the temporary speed limit, and it is difficult to control whether the issued train speed limit command is correct, and the dispatcher may issue the wrong dispatch due to misoperation. order, which lays a safety hazard for the normal operation of the train. Therefore, how to effectively ensure the accuracy and reliability of the effective issuance of the temporary speed limit order is a technical problem that needs to be solved
