Example Embodiment

[0022] Hardware implementation plan reference figure 1 Explain: Noise sensor and vibration sensor 1-1,1-2,...,1-n and speed sensor 2 are connected to the analog input front-end processor 3, and the analog input front-end processor 3 is connected to the computer 4. Software implementation plan reference figure 2 Explain: The user selects the number of noise sensors and vibration sensors through the software operation interface, and determines whether to enable speed measurement, and then starts the measurement control software module; the measurement control software controls the analog input front-end processor AD73360 to collect the data of each sensor in a cyclic detection mode. The multi-sensor information fusion software module will fuse the signals of each sensor and store the fused signals in the internal database; the spectrum analysis software module will fuse the noise and vibration signals before and after the fusion Both perform spectrum analysis and display the spect...

Abstract

An instrument based on virtual instrument technique for measuring and analyzing the noise of multiple sensors including mois sensor, vibration sensor, and rotation speed sensor is composed of sensors, front-end processor with analog input, and PC with measuring software module for analyzing digital signals. Its advantages are high measuring precision, and high resolution.

Description

technical field [0001] The invention relates to a measurement analyzer, in particular to a multi-sensor noise and vibration measurement analyzer based on virtual instrument technology which can be used to measure, analyze and evaluate the noise and vibration of complex mechanical systems. Background technique [0002] Mechanical components will generate noise and vibration during their movement, both of which are inseparable, and both are embodied as mechanical waves. [0003] In the electromechanical industry, in order to improve product quality, find system faults, or comprehensively evaluate the overall performance of products, etc., it is necessary to measure the noise and vibration of mechanical systems or components. The structure and working principle of the noise and vibration measuring instrument are basically the same, and it is composed of a sensor, a signal conditioning circuit, an A / D converter, a spectrum analysis software and a display. [0004] At present, t...
