Method for performing movement authorization control on trains

Abstract

The invention provides a method for controlling movement authorization of trains. The method mainly includes: when the radio blocking center RBC judges that a blocking area is occupied (or abnormal) within the range of the driving permit sent to the train, and the occupied (or abnormal) blocking area is not an adjacent blocking area of ​​the blocking area where the train is located, At this time, RBC sends a conditional emergency stop CEM message to the train; after the train receives the CEM message, according to the location information of the emergency stop point in the CEM message, the train judges whether the current position of the train has crossed the position of the emergency stop point, and according to the judgment result Decide whether to execute the CEM message. After the present invention receives the CEM message through the train, it judges whether the current position of the train has crossed the position of the emergency stop point, and decides whether to execute the CEM message according to the judgment result, which can avoid when the train running speed is relatively high, or the position report interval In larger cases, it will cause the train to brake and stop in an emergency.

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
