Problems solved by technology

The existing motor health management is to access the diagnostic information provided by all the motor expert systems in the background, and set up a special workstation to analyze the diagnostic information. The accuracy and effectiveness are based on the expert system. If there is no expert system in the factory area, then Motor health management cannot be carried out, on-site installation and construction are complicated, and it needs to be developed according to the actual situation of the factory, which cannot be widely promoted. The cost performance of research and development is low, which indirectly increases the cost of the system and is difficult to promote.

Embodiment Construction

[0058] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0059] This patent provides a variety of parallel schemes, and the different expressions belong to the improved scheme based on the basic scheme or the parallel scheme. Each scheme has its own unique characteristics.

[0060] In order to solve the existing above-mentioned deficiencies, the present invention intends to use the motor three-phase voltage, current signal, temperature signal, and vibration signal as the source of the motor signal, and build a motor fault diagnosis model to uniformly analyze motor faults such as single-phase grounding of the stator winding, phase-to-phase faults, etc. Faults such as short circuit, stator winding turn-to-turn short circuit, ...

Abstract

The invention relates to the field of motor fault diagnosis, online monitoring, intelligent operation and maintenance and health management, in particular to an intelligent operation and maintenance and health management system for a motor. The system comprises a data acquisition module, a data analysis module and an intelligent operation and maintenance module. The data acquisition module, the data analysis module and the intelligent operation and maintenance module are respectively in communication connection with the CPU; the data acquisition module is used for connecting a voltage and current transformer signal, a vibration sensor signal and a temperature sensor signal into the device and synchronously acquiring three-phase current, voltage data, vibration data and temperature data, wherein the vibration sensor collects data of a motor bearing end cover or a bearing seat in the horizontal and vertical directions, and the temperature sensor collects a motor stator three-phase winding temperature signal; and the data analysis module is used for establishing a data analysis model, classifying fault stages according to labels, generating a fault analysis report, storing the fault analysis report in the data storage module, and transmitting a fault stage instruction back to the CPU.

Description

technical field [0001] The invention relates to the fields of motor fault diagnosis, on-line monitoring, intelligent operation and maintenance and health management, in particular to an electric motor intelligent operation and maintenance and health management system. Background technique [0002] According to incomplete statistics, in military and industrial fields such as power generation, coal mines, metallurgy, cement, and submarines, most of the production tasks are completed by rotating machinery. Among them, the electric motor is a key rotating equipment that provides power and auxiliary functions. The role and value of substitution. As a very mature product, the electric motor has very high reliability and safety. However, with the increasingly complex working conditions and improper on-site operation, the electric motor often has mechanical or electrical failures, resulting in production line stagnation and equipment maintenance cycle. lengthened, resulting in unne...
