Problems solved by technology

When the suspension controller fails, the correct control signal cannot be generated, which will cause the suspension system to become unstable and affect the train operation
After the commercialization of maglev trains, a large number of controllers and effective detection methods for the controllers are required, but the current off-line detection and diagnosis methods for the suspension controllers cannot meet the requirements. Therefore, how to realize a suspension controller detection platform has a practical demand and has become Key technical issues to be resolved

Embodiment 2

[0050] This embodiment is basically the same as Embodiment 1, and the difference is that the realization form of the load unit 2 is different. Embodiment 1 uses electromagnets and rails to realize the load unit 2. The structure is complicated, the space is large, and the cost is high. The device may be damaged during the test, but in this embodiment, the load unit 2 is realized by using a dummy load equivalent to an electromagnet, and the load unit 2 is small in size, and is arranged in a separate load cabinet.

[0051] Such as Figure 11 As shown, the load unit 2 includes an electromagnet electrical simulation branch circuit 24 and a mechanical characteristic simulation operation chip 25. The electromagnet electrical simulation branch circuit 24 is connected with the electromagnet joint 43 of the detected suspension controller 4 (output current voltage u), and the electromagnetic The ferroelectric analog branch 24 includes a power inductor 241 and a power resistor 242 connected...

Abstract

The invention discloses a suspension controller detection device for a medium and low speed maglev train. The suspension controller detection device for the medium and low speed maglev train comprises a power supply unit, a load unit and a detection unit, wherein the detection unit comprises a detection control computer, a signal generator and a signal collector, the power supply unit is connected with the detection unit and a power input connector of a suspension controller to be detected, the signal generator is connected with a sensor connector of the suspension controller, the signal collector is connected with an electromagnet connector of the suspension controller through the load unit, and the detection control computer is connected with a communication connector of the suspension controller. The suspension controller detection device for the medium and low speed maglev train not only can comprehensively test suspension performance of the suspension controller before the suspension controller is loaded on the medium and low speed maglev train so as to guarantee that the suspension controller can normally work after being loaded on the medium and low speed maglev train, but also can position breakdowns when the train suspension controller breaks down so as to facilitate maintenance, has dual functions of rapidly detecting the performance of the suspension controller and diagnosing the breakdowns of the suspension controller, and can improve running reliability and stability of the maglev train.

Description

technical field [0001] The invention relates to the field of Electro Magnetic Suspension (EMS) type medium and low speed maglev trains, in particular to a suspension controller detection device for medium and low speed maglev trains. Background technique [0002] As a new type of rail transit that relies on the electromagnet installed on the car body to generate attraction to the track to suspend the train on the track, the medium and low-speed maglev train has the advantages of low mechanical wear, strong climbing ability, and small turning radius. As the key functional unit in the maglev system of the entire medium-low speed maglev train, the suspension controller has a direct impact on the safe operation of the medium-low speed maglev train whether its performance is good or bad and whether it works normally. [0003] Such as figure 1 As shown, the interior of the suspension controller is composed of the main circuit strong current part and the weak current control part....
