Problems solved by technology

The current monitoring method is usually based on wired or wireless measurement equipment to carry out corresponding equipment monitoring and diagnosis. Due to the equipment operating environment and the mechanism of the equipment itself, the installation of wired measurement equipment is greatly restricted; the type of equipment targeted by infinite measurement Limited, covering a small range of equipment. At the same time, it is difficult to realize the measurement of complex equipment and the transmission of high-frequency signals. At the same time, the layout of the power supply is relatively strict.

Embodiment

[0027] like figure 1 As shown, the method for intelligent monitoring of equipment abnormal operation status of the present invention includes the following steps:

[0028] Step S1: Equipment selection and on-site deployment: According to the characteristics of the nuclear power equipment under test and the industrial scene where it is located, geometric parameters such as the number, aperture size, sensor element spacing, and spatial distribution form of the microphone array in the acoustic camera need to be considered. The microphone sensor requires a certain measurement frequency range and beamforming range, with a high signal-to-noise ratio, a high sampling frequency, and a suitable measurement distance. At the same time, the convenience of the sensor array in manufacturing, installation and transportation, as well as the radiation resistance characteristics of the microphone sensor in the special industrial environment of nuclear power should be considered;

Abstract

The invention aims to disclose a method for intelligently monitoring an abnormal operation state of equipment. Compared with the prior art, comprehensive perception of equipment is realized in a non-contact manner; equipment state information is obtained by monitoring sound generated during equipment operation, and the defects of traditional sensing data can be effectively overcome; and meanwhile, fault monitoring diagnosis and predictive maintenance of the equipment and full-life-cycle management of the industrial equipment are realized based on big data and deep learning, so that the aim of the invention is fulfilled.

Description

technical field [0001] The present invention relates to a method for intelligent monitoring of equipment, in particular to a method for intelligent monitoring of abnormal operation status of equipment based on sound collection, sound field processing and deep learning. Background technique [0002] When nuclear power equipment operates abnormally, in addition to the abnormality of relevant operating parameters, it is usually accompanied by specific identifiable sounds. By monitoring and analyzing such sounds, it is often possible to effectively analyze whether the operating status of the equipment is normal. The current monitoring method is usually based on wired or wireless measurement equipment to carry out corresponding equipment monitoring and diagnosis. Due to the equipment operating environment and the mechanism of the equipment itself, the installation of wired measurement equipment is greatly restricted; the type of equipment targeted by infinite measurement Limited,...
