Magnetic suspension air blower control device based on Internet of Things

Abstract

The invention relates to the technical field of remote control over air blowers, and discloses a magnetic suspension air blower control device based on Internet of Things. The magnetic suspension airblower control device comprises a PLC, a power amplifier, a MOSFET, a current sensor, a displacement sensor, an A / D circuit converter and a communication module, wherein the current sensor comprises afirst current sensor body and a second current sensor body, and the first current sensor body is used for detecting current of an upper electromagnetic coil of a magnetic suspension air blower, and outputting current signals of the upper electromagnetic coil to the A / D circuit converter. The magnetic suspension air blower adopts the Internet-of-Things control technology of the PLC and the communication module, thus a rotor of the magnetic suspension air blower stably suspends and rotates at a high speed, remote control over the running state of the blower in the whole process is also achieved, thus normal work of the system is guaranteed, and accidents are limited within the minimum range. In the meanwhile, the magnetic suspension air blower control device also has the functions of storage and remote collection control, and convenience is brought for workers to analyze failure data.

Description

technical field [0001] The invention relates to the technical field of blower remote control, in particular to a magnetic levitation blower control device based on Internet of Things technology. Background technique [0002] The magnetic levitation blower is a new type of high-efficiency energy-saving and environmental protection equipment based on the application of active magnetic levitation bearing technology and high-speed permanent magnet synchronous motor technology on the basis of traditional air blowers, and the integrated design. The active magnetic levitation bearing system is the core system of the magnetic levitation blower, and the motor rotor is fixed. Between two radial magnetic bearings and two axial magnetic bearings, the position of the rotor is detected by a position sensor, and the position signal is reflected to the magnetic bearing controller in real time. When the rotor deviates, the controller will The displacement adjusts the magnetic field force of ...

Problems solved by technology

[0003] A Chinese patent discloses a maglev blower control system based on the Internet of Things (authorized announcement number CN110230606A). This patented technology accurately detects the on-site working conditions through temperature sensors and humidity sensors, and finally generates the collected data in time through the Internet of Things. Host computer and handheld terminal; that is, the present invention can realize real-time remote detection of the working state of the magnetic levitation blower, provide valuable data for the later research and development of the magnetic levitation blower, and when a fault occurs, it can cut off the power supply in time to prevent problems before they happen, but It cannot guarantee that the entire system can still maintain normal operation when a fault occurs, and it does not have storage and remote collection and control functions, which makes it difficult for staff to analyze fault data
