Internet-of-things three-phase asynchronous motor monitoring control device and monitoring control method thereof

Abstract

The invention discloses an Internet of Things three-phase asynchronous motor monitoring control device and a monitoring control method thereof, and the device comprises an MCU, a current sampling module, a voltage sampling module, a metering module, a wireless communication module, and a switch module. The current sampling module and the voltage sampling module are both connected with the metering module, the metering module, the wireless communication module and the switch module are all connected with the MCU, the switch module is used for driving the low-voltage direct-current relay, the low-voltage direct-current relay is used for controlling the alternating-current contactor, the alternating-current contactor is used for controlling the motor, and the wireless communication module is used for communicating with a cloud platform. According to the method, various faults occurring in the operation process of various motors can be quickly and accurately recognized, the alternating current contactor is automatically controlled to cut off the load in an abnormal state, information is reported in real time, and a user is reminded to take corresponding measures.

Description

technical field [0001] The invention belongs to the electromechanical field, and in particular relates to a monitoring and control device for a three-phase asynchronous motor of the Internet of Things and a monitoring and control method thereof. Background technique [0002] At present, China's agricultural production uses a large amount of electric machinery, but most use scenarios rely on manual switches, which are time-consuming and labor-intensive, not intelligent enough, and inefficient. At present, there are a large number of wireless switch products in the market, the main communication methods are wifi, super heterodyne, GPRS, 4g. Products through superheterodyne communication are controlled by a remote controller paired with the terminal one-to-one. This type of product can only be controlled in one direction, and the control distance is about 300m. It is even lower in complex scenes with occlusion. In low occasions, its low price has an advantage in comparison. P...
