Wireless monitoring device for rotary machine vibration

Abstract

The invention discloses a wireless monitoring device for rotary machine vibration. The wireless monitoring device comprises a vibration parameter acquisition module arranged on a target component, aninfrared distance measurement group arranged around the target component, and a PC equipped with a LoRa wireless communication module, wherein the vibration parameter acquisition module and the infrared distance measurement group transmit acquired vibration parameters of a target component and distance parameters between each monitoring point of the target component in the rotating process and theinfrared distance meter to the PC through the LoRa wireless communication module respectively; and the PC evaluates the vibration condition of the target component based on the vibration parameter ofthe target component and the distance parameter between each monitoring point of the target component in the rotating process and the infrared range finder. According to the invention, real-time acquisition of mechanical vibration data is realized based on the vibration sensor carrying the three-dimensional attitude sensor and the infrared range finder, and then acquisition of final mechanical vibration parameters is realized based on an adaptive fusion algorithm, so that the accuracy is relatively high.

Description

Technical field [0001] The invention relates to the field of mechanical monitoring, in particular to a wireless monitoring device for vibration of rotating machinery. Background technique [0002] At present, the maintenance and monitoring of machinery is basically carried out by means of periodic inspections by maintenance personnel. While time-consuming and laborious, there are generally poor real-time defects, so that the hidden dangers of machinery cannot be found in time. At the same time, the existing human inspection process Among them, the monitoring of mechanical vibration mostly relies solely on the detection of the vibration sensor, which does not consider the influence of the posture information of the vibration sensor itself, which makes the error of the detection result to a certain extent larger. Summary of the invention [0003] In order to solve the above problems, the present invention provides a wireless monitoring device for vibration of a rotating machine, w...

[0002] At present, the maintenance and monitoring of machinery is basically carried out in the way of periodic inspection by maintenance personnel, which is time-consuming and laborious. At the same time, there are generally defects of poor real-time performance, so that hidden dangers of machinery cannot be discovered in time. At the same time, the existing manual inspection process Among them, most of the monitoring of mechanical vibration relies solely on the detection of vibration sensors, which does not take into account the influence of the attitude information of the vibration sensor itself, which leads to a large error in the detection results to a certain extent.
