Embodiment 1
[0035] see figure 1 , which is a method flow chart of a method for controlling a medium-low speed maglev train disclosed in Embodiment 1 of the present application, specifically including:
[0036] Step 101: Detect the levitation current of the levitation system;
[0037] Preferably, the levitation current of the levitation system is collected by a current sensor for detection.
[0038] Step 102: judging whether the levitation current is greater than a rated value;
[0039] Step 103: When the levitation current is greater than a preset rated value, reduce the traction force of the linear traction motor.
[0040] Medium and low-speed maglev trains rely on electromagnetic attraction to levitate the train to a certain height, realizing the non-mechanical contact between the train and the local track, and then use the linear motor to drive the train to run. The suspension force of the train suspension system is the attraction force between the electromagnet and the track genera...
Embodiment 2
[0045] Because the control method of a medium-low speed maglev train in the first implementation determines whether to adjust the traction force by judging whether the levitation current exceeds the rated value. Because the levitation current will be affected by many factors and change, not only the change of the levitation force caused by the change of the normal force will eventually cause the change of the levitation current. Therefore, in order to make the judgment and control results more accurate, the present invention also provides another control method for medium- and low-speed maglev trains. For details, please refer to figure 2 The shown method flowchart specifically includes:
[0046] Step 201: detecting the normal force of the linear traction motor and the suspension current of the suspension system;
[0047] Preferably, the normal force of the linear traction motor is detected by the suspension controller.
[0048] In the traction working condition, the normal...
Embodiment 3
[0056] Corresponding to the method for controlling a medium-low speed maglev train in the first embodiment above, this embodiment of the present application provides a control device for a medium-low speed maglev train. see image 3 , which is a device structure diagram of a control device for a medium-low speed maglev train disclosed in Embodiment 3 of the present application. The device includes: a first detection module 301 , a first judgment module 302 and a first processing module 303 . The following will further introduce its internal structure and connection relationship in combination with the working principle of the device.
[0057] The first detection module 301 is used to detect the suspension current of the suspension system;
[0058] A first judging module 302, configured to judge whether the levitation current is greater than a rated value;
[0059] The first processing module 303 is configured to reduce the traction force of the linear traction motor when the...
