Vibration sensor with diagnostic function and method for detecting vibration of moving equipment

Abstract

The invention discloses a vibration sensor with a diagnostic function, comprising: an embedded central processing unit; a low-frequency vibration collector, which collects the vibration data of the natural frequency of the moving equipment when it is not in operation, and stores it in a storage unit. The unit also pre-stores the fault frequency data corresponding to different types of faults generated according to the natural frequency vibration data of the moving equipment; the high-frequency vibration collector collects the vibration data of the moving equipment in the running state; the embedded central processing unit converts the natural frequency vibration The data is filtered out from the vibration data collected by the high-frequency vibration collector, and the processed data is compared with the pre-stored fault frequency data. If there is a coincidence, a fault occurs and an alarm message is generated. The sensor can effectively remove the interference data generated by the natural frequency characteristics of the moving equipment itself, making the obtained data more accurate and real, and also capable of real-time diagnosis and real-time early warning. The invention also provides a vibration detection method of the moving 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.
