Problems solved by technology

At present, the interior of the suspension controller generally adopts a single unit design. When any component fails, it is easy to cause the failure of the suspension controller, which makes the redundancy of the suspension controller insufficient, and the mean time between failures is greatly affected by key components.

Embodiment 1

[0036] A suspension controller, including a weak current structure and a strong current structure connected to each other. The weak current structure is mainly used for signal processing and suspension control digital operation units, and outputs control information for the strong current part. The strong current structure is mainly used to realize the control of the output current control, specifically, as image 3 As shown, the weak current structure includes a signal acquisition unit, an arbitration control unit, a core computing control unit, and a signal conversion and transmission unit. The arbitration control unit is used to monitor the working status of each core computing control unit in real time, determine the accuracy of the core computing control unit, select The optimized control calculation amount is output; the signal conversion and transmission unit is used to realize the signal reception, conversion and transmission; the signal acquisition unit is used for the...

Embodiment 2

[0041] A suspension control system, including a suspension controller, a suspension module and a sensor installed on the suspension module, the suspension controller is connected to the suspension module, the suspension controller is the suspension controller described in the first embodiment above, and the aforementioned signal acquisition The unit is also used to collect information from the sensors.

[0042] In a further technical solution, the sensor includes an acceleration sensor, a gap sensor and a current sensor arranged in parallel, the acceleration sensor is used to measure the vertical motion acceleration of the suspension module, and the gap sensor is used to measure the suspension gap of the suspension module ; The current sensor is used to measure the suspension current of the suspension module. The measurement information of the acceleration sensor, gap sensor and current sensor is finally transmitted to the suspension controller.

[0043] In addition, it should ...

Embodiment 3

[0045] like Figure 4 As shown, a suspension control method of the present invention comprises the following steps:

[0046] Step 1: After the system is powered on and initialized, it starts to run;

[0047] Step 2: The signal acquisition unit collects the sensor information and the internal information of the suspension controller;

[0048] Step 3: Transmit the collected sensor information and the internal information of the levitation controller to several independent core computing control units through the signal conversion and transmission unit;

[0049] Step 4: Each independent core calculation control unit performs calculation according to the pre-designed control strategy, and sends the calculation result to the arbitration control unit;

[0050] Step 5: Verify the data calculated by the core computing control unit through the arbitration control unit, detect all core computing control units, output the correct data to the signal conversion and transmission unit, and...

Abstract

The invention discloses a maglev train and a levitation control system, controller and control method of the maglev train. Core computing control units are utilized for multi-machine hot standby redundancy, by additionally arranging multiple independent and parallel core computing control units, when the core computing control units break down, quick switching can be achieved through an arbitration control unit, and the output of the levitation controller and the stability of the levitation control system are not influenced; the core computing control units can achieve real-time communication,and the maglev train and the levitation control system, controller and control method of the maglev train have the advantages of being simple in structure, high in reliability, high in fault rate andlow in cost.

Description

technical field [0001] The invention relates to the field of maglev traffic suspension control systems, in particular to a maglev train suspension controller capable of hot standby redundancy, a control system, a control method and a maglev train including the suspension control system. Background technique [0002] The suspension controller is one of the core systems of the maglev train, and its stability and reliability are directly related to the stability and reliability of the maglev train operation. See figure 1 , the electromagnetic levitation modules of the maglev train are all controlled by the levitation controller to realize the levitation function. Each car of the maglev train is composed of at least 10 levitation controllers. The failure of any one controller will cause the maglev train to not operate normally. Therefore , high reliability, safety and stability of the suspension controller is the guarantee for the normal operation of the maglev train. [0003]...
