Maglev train and whole-vehicle centralized suspension control system applied to maglev train

Abstract

The invention discloses a maglev trainand a whole-vehicle centralized suspension control system applied to the maglev train. The maglev train comprises an integrated controller, a plurality of suspension modules, a plurality of power driving modules and a plurality of suspension sensors, wherein the integrated controller and all the power driving modules form a communication looped network, two-way data transmission is achieved between the adjacent power driving modules, each power driving module is at least connected with two suspension sensors, the suspension sensors interact with the power driving modules, each suspension module is at least provided with two suspension sensors, and the centralized controller adopts a multi-core controller. In order to achieve the optimal suspension performance of the whole train, the state information of the whole maglev train and the state information of the centralized suspension control system of the whole train are collected through the suspension sensors, the centralized controller is guided to carry out calculation, the calculated suspension control quantity information is sent to all the power driving modules, the centralized suspension control system is controlled in real time, and a powerful guarantee is provided for stable suspension and health management of the maglev train.

Description

technical field [0001] The invention mainly relates to the technical field of maglev trains, in particular to a maglev train and a vehicle centralized suspension control system for it. Background technique [0002] The control system of the maglev train is an important component of the maglev train. The traditional maglev train control system uses a distributed suspension control system. One train consists of 10 or 20 suspension controllers to control 10 electromagnets, and one train consists of 10 / 20 suspension controllers. A single suspension controller includes two parts, the suspension control computer and the power drive module. The suspension control computer sends a PWM (Pulse width modulation, pulse width modulation) control signal to the power drive module for output after receiving the external information. Different suspension controllers are independent of each other, and the whole vehicle has 10 / 20 suspension control computers. The disadvantages of independen...

Problems solved by technology

[0004] 2) 10 sets of suspension control computers are used, and each set of control computers has a hot backup system, which is high in cost and low in reliability

[0005] 3) There is a large amount of vehicle status information, and the uniform computing capability of a single suspension controller is limited, which cannot be fully utilized and cannot store real-time suspension system data, making it inconvenient to realize intelligent control, vehicle health management and full life cycle monitoring
