Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] The present invention is mainly used for electromagnetic maglev trains, and the schematic diagram of the carriage of the module suspension system of electromagnetic maglev trains is as follows: figure 1 and figure 2 shown. Suspension modules (1n, wherein n=1, 2, ..., 8) are the basic suspension units of the train, and several suspension modules are symmetrically distributed on the bottom of each carriage both sides, and the number of suspension modules on each side depends on the specific model of the train. As shown in the figure, the number of suspension modules in this embodiment is 8, and the suspension modules 11, 12, 13, 14, 15, 16, 17, and 18 are divided into two parts and arranged symmetrically at the bottom of both sides of the carriage.

[0021] Such as image 3 Shown, the distributed active fault-tolerant control...

Abstract

The present invention relates to a distributed active fault-tolerant control system of suspension module of electromagnetic maglev train. The control system comprises 8 electromagnets which are arranged on the suspension module, 4 independent suspension controllers, a first sensor group and a second sensor group; the 8 electromagnets are divided into 4 electromagnet groups; each electromagnet group comprises two electromagnets which are connected in series; each suspension controller is connected with an electromagnet group through a chopper; the first sensor group and the second sensor group are respectively arranged at two ends of the suspension module; the suspension controller, the first sensor group and the second sensor group are connected through a CAN bus; the suspension controller is connected with the vehicle monitoring system of the maglev train. The distributed active fault-tolerant control system of the suspension module of the electromagnetic maglev train can tolerate failures of the controller, the sensor and the actuator in the suspension system, and thus greatly improve the reliability, stability and security.

Description

technical field [0001] The invention mainly relates to the field of levitation control systems of maglev trains, in particular to a distributed active fault-tolerant control system of levitation modules of electromagnetic maglev trains. Background technique [0002] In the prior art, the suspension control system is an important part of the maglev train system. During the high-speed operation of the maglev train, once a certain controller, sensor or actuator (chopper or electromagnet) of the levitation system fails, the corresponding levitation point will be unstable or invalid, and the loss caused at this time will be difficult. Estimated. Engineering practice shows that the failure of controllers, sensors and actuators has become the main cause of suspension control system failure. Faced with such a large and complex maglev train suspension control system, improving its safety, reliability and effectiveness has become a key technical requirement. Contents of the invent...
