Vibration sensor with diagnosis function and dynamic equipment vibration detection method thereof

Abstract

The invention discloses a vibration sensor with a diagnosis function. The vibration sensor comprises an embedded central processing unit; a low-frequency vibration collector used for collecting vibration data of inherent frequency of the dynamic equipment in a non-running state and storing the vibration data in a storage unit, wherein fault frequency data corresponding to different types of faults generated according to the vibration data of the inherent frequency of the dynamic equipment is pre-stored in the storage unit; and a high-frequency vibration collector used for collecting vibration data of the dynamic equipment in a running state. The embedded central processing unit filters the inherent frequency vibration data from the vibration data collected by the high-frequency vibration collector and compares the processed data with pre-stored fault frequency data, and if the processed data are consistent with the pre-stored fault frequency data, a fault occurs and alarm information is generated. The sensor can effectively remove interference data generated by inherent frequency characteristics of dynamic equipment, so that the obtained data is more accurate and real, and meanwhile, real-time diagnosis and real-time early warning can be realized. The invention also provides a vibration detection method of the dynamic equipment.

Description

technical field [0001] The invention relates to the technical field of vibration sensors. More specifically, the present invention relates to a vibration sensor with a diagnosis function and a method for detecting vibration of its moving equipment. Background technique [0002] Mechanical vibration refers to the reciprocating motion of an object near the equilibrium position. During the process of mechanical vibration, some physical parameters of the vibrating object, such as displacement and speed, will change repeatedly, which will bring certain impact to daily life and engineering projects. harm. For example, vibration will aggravate the fatigue and wear of components, shorten the service life of machines, etc. The purpose of the vibration test is to simulate a series of vibration phenomena, to test whether the product can withstand the test of the vibration environment during transportation or use during the life cycle, and to determine the required standards for produ...

Problems solved by technology

When the collected data is directly uploaded to the platform software, it brings a lot of interference to the data analysis of the platform software, and the analysis results are not accurate at all.

In addition, after the original vibration data is collected, it must be uploaded to the platform. After analysis with the analysis software of the platform, conclusions can be drawn and faults can be distinguished. Require

Moreover, the faults that need to be dealt with urgently cannot be dealt with in time, which is very late and will cause great economic losses at the same time.
