Method for adjusting train operation curve

Abstract

The invention discloses a method for adjusting a train operation curve. A plurality of check points are arranged between stations; an ATO (automatic train operation) system in a train calculates the train operation curve according to train operation time, which is issued by an ATS (automatic train supervision) system, between the two stations and determines scheduled arrival time of each check point between the two stations; and the ATO system adjusts the train operation curve according to actual arrival time and the scheduled arrival time of the train at each check point. Thus, the ATO system can adjust the operation curve while operating according to the operation curve, and the on-schedule rate of the train is improved.

Description

technical field [0001] The invention relates to the field of urban rail transit, in particular to a method for adjusting train running curves. Background technique [0002] Urban rail transit is becoming an increasingly important travel mode in a city, and the punctuality rate has become an important evaluation index of this travel mode. [0003] At present, the industry adjusts the running time between train stations: the ATS (Automatic Train Supervision, automatic train monitoring) system issues the inter-station operation level, and the ATO (Automatic train operation, automatic train operation) system calculates and adjusts the two times according to the operation level. The running curve between stations, and control the train to run according to the running curve, so as to realize the punctual running of the train. However, this adjustment method has certain defects. It is the ATS system that adjusts the running curve, and the ATO system controls the train to run accor...

Problems solved by technology

However, this adjustment method has certain defects. It is the ATS system that adjusts the running curve, and the ATO system controls the train to run according to the running curve. After the train arrives at the station, the ATS system compares the actual arrival time of the train with the planned arrival time. The time difference can be used to calculate whether the train is on time, so as to calculate the operation level of the next station of the train, and then send it to the ATO system. The ATO system will run between stations according to the operation level issued by the ATS system, which is equivalent to During the entire process, the running speed will not change even if the speed limit remains unchanged, and it cannot be adjusted according to actual changes. The actual running time of the train will be different from the time planned by the ATS system, which will cause the train to be adjusted from non-punctual The time required for punctual operation becomes longer, which is finally reflected in the decrease of train punctuality rate
