Pantograph bow net adaptive control system and method

Abstract

The invention provides a pantograph bow net adaptive control system and a control method. The control system comprises a first GPS unit, a second GPS unit and a controller, wherein the first GPS unitis used to collect and record GPS information of a cross-network area track path; the second GPS unit is used to record the GPS information of a vehicle travel path; the controller receives GPS information data of the first GPS unit and the second GPS unit; the controller includes a data matching unit and a control signal generation unit; the data matching unit is used to carry out matching calculation on the data of the first GPS unit and the second GPS unit; and the control signal generation unit is used for generating a pantograph control signal when the data is matched. The control methodcomprises the following steps of collecting the GPS information of the cross-network area track path and the GPS information of the vehicle travel path; carrying out matching calculation on the GPS information of the track path and the GPS information of the travel path; and if the GPS information is matched, generating the pantograph control signal. Based on a matching algorithm, an adaptive control strategy is automatically generated and accurate control is realized.

Description

technical field [0001] The invention relates to the technical field of train control, in particular to a pantograph-catenary adaptive control system and method. Background technique [0002] The train runs through the pantograph to get electricity. 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 rail is 5.3 meters. The intersection area of ​​the 4 types of net heights and catenaries of different net height types is called the cross-network area. [0003] Taking the high-speed EMU as an example, sometimes it runs on the catenary section dedicated to high-speed rail, and sometimes it runs on the catenary section of other express trains or freight trains. The height of the catenary in each network segment is different. When the train runs across the n...

AI Technical Summary

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
