Train automatic control method and device, on-board ato

Abstract

The present invention provides an automatic train control method and device, and a vehicle-mounted ATO, wherein the method includes: obtaining the current position and target of the train by obtaining the arrival time and the current time of the target station that needs to stop in front of the train during the running process The distance between the stations is based on the arrival time, the current time, the distance and the track information of the current running section of the train to obtain the best running curve of the train, and control the train to run according to the best running curve. In this embodiment, the on-board ATO automatically calculates and adjusts the trains running curve in real time during the interval operation according to the arrival time sent by the ATS and the current time of the system, so that the train can follow the optimal running curve in the entire operation interval. Driving can make the train arrive at the predetermined parking position with a more accurate arrival time, and reduce the probability of the train running late or arriving at the station early.

Description

technical field [0001] The invention relates to the technical field of train safety, in particular to a train automatic control method and device, and a vehicle-mounted ATO. Background technique [0002] The on-board automatic train protection system (Automatic Train Protection, referred to as ATP) on the existing train can calculate the safety protection curve of the train according to the safety speed limit of the train, the performance parameters of the train, etc. [0003] In order to ensure the punctual operation of the train, the automatic train supervision system (Automatic Train Supervision, referred to as ATS) on the ground calculates the running timetable of the train. ATS calculates the running speed of the train according to the running timetable and the position of the train, and then passes A wireless or active transponder transmits the travel speed to the train. The automatic train operation system (Automatic Train Operation, referred to as ATO) controls the ...

AI Technical Summary

Problems solved by technology

In the process of controlling train operation according to the fastest section operating speed or the operating speed sent by ATS, ATO cannot guarantee that there will be no discrepancy between the time when the train runs to the next station and the arrival time stipulated in the train timetable. big time difference

Especially when the train is running in the section, the train may temporarily stop due to other reasons. When ATO still runs at the speed of ATS, it may cause delays. If it runs at the fastest speed, it may cause early arrival at the station and affect other The running timetable of trains, or other operations affecting the platform, such as track inspection, cleaning, etc.
