Adaptive control system and method for pantograph and catenary

Abstract

The invention provides a pantograph-network adaptive control system and a control method. The control system includes: a first GPS unit: used to collect and record GPS information of track paths in a cross-network area; a second GPS unit: used to record vehicles GPS information of the travel path; the controller receives the GPS information data of the first GPS unit and the second GPS unit; the controller further includes: a data matching unit: used for matching and calculating the data of the first GPS unit and the second GPS unit ; Control signal generation unit: used to generate the pantograph control signal when the data is matched. The steps of the control method are as follows: collect GPS information of the track path in the cross-network area and GPS information of the vehicle driving path; perform matching calculation on the GPS information of the track path and the GPS information of the driving path; if matched, generate a pantograph control signal. Based on the matching algorithm, the invention automatically generates an adaptive control strategy and realizes precise control.

Description

technical field [0001] The present invention relates to the technical field of train control, in particular to a pantograph and catenary adaptive control system and method. Background technique [0002] The train runs to get electricity through the pantograph. In order to obtain electricity normally, it is necessary to ensure that the pantograph is in normal contact with the power grid. The height between the ground subgrade and the pantograph catenary in some railway sections is inconsistent. The standard height of the high-speed railway network is 5.3 meters. In some areas, existing lines and high-speed railway lines are crossed and used. There are 5 meters, 5.3 meters, 6 meters, and 6.4 meters. 4 types of net height, the intersection area of ​​different net height types of catenary, we call it the cross-net area. [0003] Taking the high-speed EMU as an example, sometimes it runs on the dedicated catenary section of the high-speed railway, and sometimes it runs on the c...

Problems solved by technology

The height of the catenary in each network segment is different. When the train runs across the network, it will lead to the section with a higher height of the pantograph catenary. The pantograph-catenary pressure is too high in the section with low net height, which accelerates the wear of the pantograph carbon brush at high speed, and in extreme cases causes the catenary to break
