A magnetic levitation system for voice-controlled space movement

Abstract

A voice-controlled spatial moving magnetic levitation system is provided with a network server, a controller, a constant-current drive circuit, a multi-channel magnetic levitation device and a magnetic levitation slice. The controller is connected with the constant-current drive circuit. The controller is provided with an embedded microprocessor, a Wi-Fi module, a microphone, an audio power amplifier circuit and a loudspeaker. The constant-current drive circuit is provided with a digital-to-analog conversion circuit and a voltage-to-current conversion circuit, and the digital-to-analog conversion circuit is connected with the voltage-to-current conversion circuit. The constant-current drive circuit is connected with the multi-channel magnetic levitation device. The multi-channel magnetic levitation device has four magnetic levitation modules, and each magnetic levitation module have a large coil and small coils. The magnetic levitation slice is provided with a ring permanent magnet inthe center thereof. The controller parses a voice password to send current data to the constant-current drive circuit, and the constant-current drive circuit outputs a constant current to drive the multi-channel magnetic levitation device and control the magnetic field intensity of the coils of the magnetic levitation modules, so that the magnetic levitation slice moves in the multi-channel magnetic levitation device and is eventually levitated on a target magnetic levitation module.

Description

technical field [0001] The invention relates to a magnetic levitation system, in particular to a magnetic levitation system for voice-controlled space movement. Background technique [0002] With the development of magnetic levitation technology, a variety of products based on small magnetic levitation such as magnetic levitation table lamps have been derived. For example, the magnetic levitation device disclosed in Chinese patent CN201610329845 adopts a magnetic repulsion type levitation device. The outer layer of the base is an annular magnet that generates a fixed magnetic field, and the inside is multiple sets of coils. The system moves to another closed-loop control system, which lacks flexibility. [0003] At present, the accuracy of voice recognition has reached a relatively high level, but there is no example of combining maglev with voice control. Contents of the invention [0004] In view of the above shortcomings, the present invention aims to provide a voice-...
