Train operation control method, device, vehicle-mounted equipment and train operation control system

Abstract

The invention discloses a train operation control method comprising the following steps: two control devices simultaneously receives the train travelling parameters transmitted by ground equipment, and the train travelling parameters received by the different control devices are different; each control device substitutes the received train travelling parameters to a segmented curve algorithm for calculating to generate corresponding train control curves; vehicle-mounted equipment selects a control device which corresponds to the current line grade CTCS; and the control device controls the train travelling speed according to the train control curve thereof. By adopting the above technical scheme, the segmented curve algorithms adopted by the different control devices are similar, the difference between the train control curves generated by each control device is small; and when the train travels to the next line grade CTCS, the train travelling speed is directly controlled by the control device corresponding to the next line grade CTCS, thus realizing non-parking automatic transformation control from the control device corresponding to the current line grade to the control device corresponding to the next line grade.

Description

technical field [0001] The present invention relates to the technical field of train control, and more specifically, relates to a train operation control method, device, vehicle-mounted equipment and train control system. Background technique [0002] CTCS (China Train Control System, China Train Operation Control System) is divided into 5 grades from 0 to 4, including on-board equipment and ground equipment. The ground equipment sends the train running parameters when the train is running to the on-board equipment, and the on-board equipment generates a vehicle control curve according to the running parameters to control the train running speed. For example: when the train is running in CTCS-2 (CTCS Level 2, China Train Operation Control System-Level 2), the on-board equipment included in CTCS-2 receives the train running parameters sent from the ground balise and track circuit in the ground equipment , such as: line parameters, temporary speed limit and EMU parameters, th...
