Aerator vector control system and method based on Internet of Things technology

Abstract

The invention discloses an aerator vector control system and method based on the Internet of Things technology. The vector control system comprises an MCU processor, a data acquisition module, a database module, a control module and a signal transmission module, wherein the input end of the data acquisition module is connected with an aerator, the output end of the data acquisition module is connected with the MCU processor, the MCU processor is respectively connected with the database module and the control module, the MCU processor is connected with an AEP platform through the signal transmission module, and the control module is connected with an FOC vector frequency conversion control unit. The working principle is simple, the intelligent degree is high, vector control can be carried out on an asynchronous motor, the starting is stable, impact cannot be caused to a speed reduction device, and the service life of the aerator is greatly prolonged; and the real internet-of-things technology is adopted, a traditional aerator is implanted into artificial intelligence, interconnection of all things is achieved, an internet-of-things control chip is directly integrated on an aerator control panel, a third-party manager product is not needed, and the breeding cost of farmers is saved.

Description

technical field [0001] The invention relates to the technical field of aerator control, in particular to an aerator vector control system and method based on Internet of Things technology. Background technique [0002] The aerators currently on the market are mainly composed of traditional AC asynchronous motor acceleration and deceleration devices. This traditional aerator has high reliability and long service life and is widely used. However, this aerator also has the following disadvantages: due to the The prototyping machine adopts AC asynchronous motor, therefore, the efficiency of the motor is not high, and the energy consumption is large; the starting mode of the motor is usually directly started by power frequency AC, which has a large impact on the gear reducer and is easy to damage the reducer; Gear reduction device, it is inevitable to maintain and lubricate the gear box, the oil seal will not be well sealed, resulting in oil leakage, long-term oil leakage into th...

[0002] The aerators currently on the market are mainly composed of traditional AC asynchronous motor acceleration and deceleration devices. This traditional aerator has high reliability and long service life and is widely used. However, this aerator also has the following disadvantages: due to the The prototyping machine adopts AC asynchronous motor, therefore, the efficiency of the motor is not high, and the energy consumption is large; the starting mode of the motor is usually directly started by power frequency AC, which has a large impact on the gear reducer and is easy to damage the reducer; Gear reduction device, it is inevitable to maintain and lubricate the gear box, the oil seal will not be well sealed, resulting in oil leakage, long-term oil leakage into the water, affecting the quality of fish; because the power supply voltage in rural areas is not stable, Therefore, the speed of the aerator is not stable, and the stability of the oxygenation efficiency is greatly reduced; the traditional aerator lacks effective monitoring means, and whether the aerator is working normally can only be on-site. Therefore, it is necessary to design a system based on the Internet of Things The technical aerator vector control system to solve the above drawbacks
