An intelligent monitoring and early warning system and method for motor protector based on internet of things

Abstract

The invention relates to the technical field of motor protection mode in industrial production, The invention particularly relates to an intelligent monitoring and early warning system of motor protector based on internet of things and a method for monitoring motor protector according to the system. The original data of motor protector, including three-phase current, three-phase voltage, active power, active power and electric energy, running state and the like, are processed through DTU-4G module accord to Modbus-A TCP protocol upload data to a database on a cloud server for storage, At the same time, the system includes Web page, Android APP and IOS client program. Each client program reads the data from the database in the cloud server and pushes it to the user for viewing and processing, which provides great convenience for the on-site maintenance personnel.

Description

technical field [0001] The invention relates to the technical field of motor protection methods in industrial production, in particular to an intelligent monitoring and early warning system for motor protectors based on the Internet of Things and a method for monitoring motor protectors based on the system. Background technique [0002] The motor plays a great role in industrial control and production. Current and voltage are the most important parameters when the motor is running. When the motor starts, the current is large. If the starting time is long, it is easy to cause heat damage to the motor. When the motor rotor is stuck due to excessive load and other reasons, the heating effect caused by the excessive locked-rotor current will easily lead to a reduction in the life of the motor, or even damage the motor; the voltage signal can truly reflect the state of the motor, and excessive voltage will cause motor insulation damage. Due to short-circuit faults and other reaso...

[0002] The motor plays a great role in industrial control and production. Current and voltage are the most important parameters when the motor is running. When the motor starts, the current is large. If the starting time is long, it is easy to cause heat damage to the motor. When the motor rotor is stuck due to excessive load and other reasons, the heating effect caused by the excessive locked-rotor current will easily lead to a reduction in the life of the motor, or even damage the motor; the voltage signal can truly reflect the state of the motor, and excessive voltage will cause motor insulation damage. Due to short-circuit faults and other reasons, the line voltage will drop sharply in a short period of time, resulting in damage to the line and motor
