Method for achieve automatic driving curve generation between stations during operation by automatic train driving system

Abstract

The present invention relates to a method for achieve automatic driving curve generation between stations during operation by an automatic train driving system. The method comprises that: the system real timely acquires operation information of an automatic train monitoring system, train parameter information and track information of a track database; the driving curve information at each operation stage between the stations is real timely and adaptively calculated; the key point information at each operation stage between the stations is extracted and recorded according to the driving curve information; the best automatic driving curve of the train between the stations during the operation is real timely generated. With adopting the method for achieve the automatic driving curve generation between the stations during the operation by the automatic train driving system, a plurality of disadvantages of the train in the automatic driving process are effectively overcome; the advantages of higher comfort, good energy saving effect, high parking precision, easy adjustment, stable and reliable work performance, and wide application range are provided; the purposes of punctual operation, energy saving operation, high comfort operation, safe and smooth operation of the train are achieved, and the operation requirements of the CBTC system are completely met.

Description

technical field [0001] The invention relates to the field of urban rail transit, and is particularly applicable to the technical field of automatic control of urban rail transit, and specifically refers to a method for generating automatic driving curves between stations in a wireless communication-based train automatic driving system. Background technique [0002] The communication-based train control system (CBTC) breaks through the limitations of the traditional railway signaling system by introducing a wireless communication system to realize real-time two-way communication between the train and the ground, and uses moving block technology to shorten the running interval, improving the operating efficiency of the train and the flexibility of the system It is the future development direction of the train automatic control system technology. The CBTC system is composed of the automatic train monitoring system (ATS), the automatic train protection system (ATP) and the autom...

AI Technical Summary

Problems solved by technology

[0004] (1) With the step-type speed curve, there are many train speed adjustment processes when the train is running between stations, which causes the comfort of passengers to decrease, and at the same time requires the traction and braking system to make corresponding adjustments continuously, which is not conducive to the train. energy-saving operation

[0005] (2) The stepped speed curve is a fuzzy running time interval based on the operation level. At the same time, when the train runs with a stepped speed curve between stations, there are many speed adjustment processes. It is difficult to realize the punctual operation of the train, which will definitely affect Operation of trains throughout the line

[0006] (3) With the step-type speed curve operation mode, it is difficult to achieve the purpose of precise parking because the speed adjustment is not continuous during the fixed-point parking process of the train.
