Maglev train levitation monitoring method and maglev train levitation monitoring system based on industrial Ethernet communication

Abstract

The invention discloses a maglev train levitation monitoring method and a maglev train levitation monitoring system based on industrial Ethernet communication. The steps of the method are as follows: each levitation control lower computer is connected with upper computers through the industrial Ethernet; by a multi-task mode, the levitation control lower computers acquire and output the levitation state data of levitation points to the upper computers and receive control commands coming from the upper computers, and at the same time, the levitation control lower computers control the levitation state of the levitation points according to the levitation state data of the levitation points and the control commands; the system comprises the upper computers and the levitation control lower computers, and each levitation control lower computer comprises a sensor group, a data acquisition board, a levitation controller, an actuating mechanism, an Ethernet controller and an Ethernet interface. The invention can display levitation data, acquire the working state of a levitation system in real time and ensure that engineers can efficiently monitor and maintain the levitation system in real time, and has the advantages of high operation speed, high system integration degree, complete functions and convenience and high efficiency in debugging.

Description

technical field [0001] The invention relates to the field of suspended trains, in particular to a method and device for monitoring the suspension of suspended trains based on industrial Ethernet communication. Background technique [0002] The suspension system is the most critical and core system of the suspension train (maglev train), which maintains the position of the vehicle suspended in the specified gap when the entire vehicle is running and stationary. Therefore, the quality of the suspension system directly affects the safe operation of the entire suspension vehicle. It is very important to grasp the status of the suspension system in real time. However, at present, the suspension train is only fully automatically controlled at the position of the specified gap, and there is a lack of suspension monitoring methods and devices for suspension trains. Therefore, it is impossible to ensure that the engineering personnel can efficiently monitor and maintain the suspensio...

Therefore, the quality of the suspension system directly affects the safe operation of the entire suspension vehicle. It is very important to grasp the status of the suspension system in real time. However, at present, the suspension train is only fully automatically controlled at the position of the specified gap, and there is a lack of suspension monitoring methods and devices for suspension trains. Therefore, it is impossible to ensure that the engineers can monitor and maintain the suspension system efficiently in real time, and the engineers cannot easily adjust the control parameters of the suspension system according to the operating conditions of the suspension train. It is very difficult to debug the suspension train
