Rotating equipment state monitoring method and device

Abstract

The embodiment of the invention provides a rotating equipment state monitoring method and device. The method comprises the following steps: acquiring equipment information of monitored rotating equipment; collecting the current acceleration vibration information of the monitored rotating equipment; inputting the acceleration vibration information into a preset target algorithm model, and outputting the current running state of the monitored rotating equipment, wherein the target algorithm model is selected from a preset algorithm model library, and is the algorithm model corresponding to the equipment information. Through the rotating equipment state monitoring method and device provided by the embodiment of the invention, the acceleration vibration information collected by a MEMS vibration sensor can be processed in real time by adopting an artificial intelligent processor, thereby obtaining the current running state of the monitored rotating equipment, the real-time monitoring of therotating equipment can be realized, the result inaccuracy caused by artificial analysis is eliminated, and the possible risk is avoided.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a method and device for monitoring the state of rotating mechanical equipment. Background technique [0002] Rotating mechanical equipment is referred to as rotating equipment. Rotating equipment is more and more widely used in daily life and production. It is very important to monitor the operating status of rotating equipment and understand the operating status of rotating equipment in real time. [0003] In the prior art, two sets of three-dimensional (X, Y, Z directions) acceleration vibration sensors are installed on the shaft seats at both ends of the rotating equipment to measure the vibration displacement vector, and the main shaft and the bearing bush (shaft seat) are monitored for the monitoring of the state of the rotating equipment. The vibration sensor uses the positive piezoelectric effect of the piezoelectric crystal. When the piezoelectric crystal is und...

AI Technical Summary

Problems solved by technology

[0004] However, in the monitoring method in the prior art, the piezoelectric sensor used is bulky, the power supply voltage is high, the battery power supply is inconvenient, and the low frequency response performance is poor

Data analysis and determination of operating status need to be judged based on workers' experience, which is highly subjective and the judgment results are inaccurate, so it is not suitable for mass promotion
