Temporary train speed limiting method and device, readable storage medium and electronic equipment

Abstract

The invention relates to a temporary train speed limiting method and device, a readable storage medium and electronic equipment. The method is applied to an area controller and comprises the steps: receiving a temporary speed limit verification command sent by an automatic train monitoring system, the temporary speed limit verification command comprising a starting point logic section ID and an end point logic section ID, and verifying the temporary speed limit verification command; according to a verification result of the temporary speed limit verification command, executing an operation of setting a temporary speed limit or an operation of canceling the setting of the temporary speed limit; when the train is in the jurisdiction range of the area controller, inquiring whether a temporary speed limit value exists in a logic section in the train movement authorization range or not, and under the condition that the temporary speed limit value exists, sending movement authorization information containing the temporary speed limit value to the train; and enabling the train to execute speed limiting braking operation according to the movement authorization information. Therefore, the data transmission quantity is reduced and the system failure rate is effectively reduced.

Description

technical field [0001] The present disclosure relates to the technical field of rail transit, and in particular, to a method, device, readable storage medium and electronic equipment for temporarily limiting the speed of a train. Background technique [0002] In the communication-based automatic train control system, the temporary speed limit is used to reduce the allowable speed in some special sections. Specifically, the temporary speed limit is a time-sensitive speed limit other than the fixed speed of the line, including planned speed limits caused by construction and maintenance operations, natural disasters, and sudden speed limits caused by line failures. [0003] In the related technology, when there is a situation that requires a temporary speed limit, the automatic train monitoring system sends all logical section IDs within the speed limit that belong to the jurisdiction of the zone controller (ZC, Zone Controller) to the zone controller, and then , the regional ...

AI Technical Summary

Problems solved by technology

However, when the temporary speed limit is set through the above-mentioned technical scheme, the automatic train monitoring system needs to send all logical section IDs belonging to the jurisdiction of the regional controller in the speed limit to the regional controller, which requires the transmission of a large amount of data. The protocol burden is increased, and the process of sending temporary speed limit information from the automatic train monitoring system to the on-board equipment is too complicated, and there are many intermediate devices passing through, and the possibility of system failure is relatively high
