Real-time monitoring method for health of running equipment

Abstract

The invention relates to the field of intelligent control, and aims at providing a real-time monitoring method for the health of running equipment. The method comprises the steps that multiple vibration temperature sensors are arranged on the running equipment, a vibration acceleration signal and a temperature signal are obtained by means of a built-in three-axis vibration sensing module, and converted into a vibration velocity effective value, a vibration waveform graph and a spectrum graph; data is transmitted to a database server through wireless communication transmission, an analysis anddiagnosis algorithm software module of a health control cloud platform extracts data and calculates the data, and an overall vibration speed effectively value and operation temperature of the runningequipment are obtained; after analysis and comparison are conducted with data in a running equipment fault knowledge base, health analysis and safety diagnosis results are obtained; while the resultsare displayed through a visual output software module in real time, real-time early-warning or alarm is given according to the default fault conditions. Accordingly, early signs of elevator failure can be found in time, major accidents are avoided and reduced, and the elevator operation life is prolonged.

Description

technical field [0001] The invention belongs to the field of intelligent control, and in particular relates to a method for real-time monitoring of the health of operating equipment, which is used for safety monitoring and fault diagnosis and analysis of operating equipment. Background technique [0002] Operating equipment includes operating equipment and rotating equipment, which are widely used in daily production and life. [0003] For example, the car frame of the equipment car is the load-bearing frame of the car body, which is composed of beams, columns, bottom beams and diagonal stay rods. The car body is composed of car bottom, car wall, car roof, lighting, ventilation device, car decoration and car control button board. The equipment car is the part of the car body that is in direct contact with people or goods, and it is particularly important to maintain safe operation. [0004] During the operation of the equipment, it is mainly driven by the traction machine ...

AI Technical Summary

Problems solved by technology

However, the vibration of the motor has the following hazards: energy consumption, which reduces the efficiency of the motor; directly damages the motor bearings, accelerates the wear of the motor bearings, and greatly shortens the normal life of the bearings; loosens the rotor poles, causing the stator and the rotor to rub against each other, resulting in The motor rotor is bent and broken; the wire binding at the end of the motor is loosened, causing the end windings to rub against each other, the insulation resistance is reduced, the insulation life is shortened, and in severe cases, insulation breakdown is caused; the operation of the foundation or other equipment supporting the motor is affected. Cause some parts to loosen, and even cause some parts to be damaged due to fatigue, resulting in accidents

[0007] At present, there is no simple and practical method for monitoring the health of operating equipment
