Method for controlling movement authorization of train

Abstract

The invention provides a method for controlling movement authorization of a train. The method comprises the steps that when a radio blocking center (RBC) determines that a block section occupancy (oranomaly) occurs within a driving permission range which is sent to the train by the radio blocking center, and the occupied (or abnormal) block section is not an adjacent block section of the block section where the train is located, at the moment, the RBC sends a conditional emergency stop message(CEM) to the train; after the train receives the CEM, the train determines whether or not the currentposition where the train is located is beyond an emergency stop position according to emergency stop position information in the CEM, whether or not to execute the CEM is determined according to a determination result. According to the method for controlling the movement authorization of the train, by determining whether or not the current position where the train is located is beyond the emergency stop position and determining whether or not to execute the CEM according to the determination result, the situation that an emergency braking is conducted on the train to make the train stop due to the fact that the train is running at a high speed or position report intervals are big is avoided.

Description

technical field [0001] The invention relates to the technical field of train operation, in particular to a method for controlling movement authorization of trains. Background technique [0002] During the operation of the train, the RBC (radio blocking center) sends a movement authorization containing multiple blocked areas or routes to train A according to the status of blocked areas or routes on the line. figure 1 Schematic diagram of movement authorization for RBC to send trains covering multiple blocked areas. Here, the number of blocked areas or routes covered by the mobile authorization includes 3 or more (including trains in blocked areas or routes). [0003] If the blocked area or approach within the movement authorization range in front of the train (the blocked area or approach separated by 1 or more from the blocked area or approach where the train is located) is in an occupied state, at this time, the movement authorization sent by RBC to the train should be sho...

AI Technical Summary

Problems solved by technology

At this time, when the running speed of the train is relatively high, the train has already crossed the N5 stop point, which will cause the train to stop with emergency braking

The reason for this phenomenon is that it does not take into account the high speed of the train or the large interval between position reports

Therefore, the use of SMA strategy may cause the problem of train brake stop affecting availability
