Problems solved by technology

[0003] As the running speed of high-speed railway trains is getting higher and higher, and the operating density is increasing, the operating environment of high-speed railway trains is also relatively more complex. In particular, my country's high-speed railway operation network adopts "mixed lines of high and medium-speed trains, and medium-speed trains run across lines" This puts forward higher requirements for high-speed train drivers, and a slight negligence may cause accidents that affect driving safety

Abstract

The invention discloses an automatic speed control method and device for a high-speed railway train. The method and device are applied to an automatic driving system of the high-speed railway train, and specifically comprise the steps: obtaining various types of operation information of the high-speed railway train in real time when the train is in an automatic driving state; calculating in combination with a train traction / braking performance period to obtain a target speed, a target point and a target acceleration; processing the target speed, the target point and the target acceleration toobtain a target control parameter; and outputting the target control parameter to an automatic driving system, so that the automatic driving system controls the high-speed railway train according to the target control parameter. According to the scheme, the speed of the high-speed railway train can be automatically controlled, so that the safe, punctual and stable operation of the high-speed railway train is ensured.

Description

technical field [0001] The present application relates to the technical field of high-speed rail, and more specifically, to an automatic speed control method and device for high-speed rail trains. Background technique [0002] As an important national infrastructure, national economic artery and popular means of transportation, the rail transit system has played a vital role in my country's economic construction, strengthening regional connections and enhancing the competitiveness of regional economic development. As a comprehensive transportation system integrating the advantages of high efficiency, safety, intelligence, energy saving and comfort, high-speed railway will become one of the preferred ways for people to travel in the future. [0003] As the running speed of high-speed railway trains is getting higher and higher, and the operating density is increasing, the operating environment of high-speed railway trains is also relatively more complex. In particular, my cou...
