Equipment vibration monitoring system based on multi-point MEMS accelerometer and wireless network

Abstract

The invention discloses an equipment vibration monitoring system based on a multi-point MEMS accelerometer and a wireless network. All point location acceleration data of monitored equipment are collected in real time by the system through a distributed multi-point MEMS acceleration sensor, the data are transmitted back to the system through a wireless communication network, comparative analysis is carried out on the data and a preset acceleration threshold value, whether vibration abnormal alarm prompts are triggered or not is judged, and thus the overall vibration state of the monitored equipment can be learnt comprehensively in time. The equipment vibration monitoring system based on the multi-point MEMS accelerometer and the wireless network can effectively solve the problems of equipment sympathetic vibration and equipment abnormal abrasion caused by sudden abnormal vibration of a certain part of the monitored equipment and yield decline caused by the equipment sympathetic vibration and the equipment abnormal abrasion. The equipment vibration monitoring system based on the multi-point MEMS accelerometer and the wireless network is especially suitable for industrial enterprises with production lines and large-scale manufacturing equipment, and is low in cost and high in reliability.

Description

technical field [0001] The invention relates to the technical field of equipment mechanical vibration monitoring, specifically a vibration state monitoring and alarming device suitable for industrial production lines or a single set of large-scale manufacturing equipment. Background technique [0002] At present, there are two main ways to detect the mechanical vibration state of large equipment: [0003] 1. Place the vibration sensor directly on the measuring part of the equipment under test to measure the vibration value of the machine. The measured vibration data is expressed in tables or patterns, and finally the equipment vibration status conclusion is obtained by comparing with the "abnormal vibration benchmark". [0004] 2. Use the spectrum analysis method to diagnose abnormal vibration. In this method, the vibration meter is generally used to detect the total value of the vibration of the equipment under test. When it is found that the vibration total value data ha...

Problems solved by technology

[0005] However, the above two mechanical vibration detection methods exist; the detection method has complicated steps, long detection cycle, more testing equipment and equipment, it is difficult to carry out long-term online monitoring of the tested equipment, single detection point, and vibration data cannot be completely recorded. Many deficiencies such as failure to send out abnormal vibration alarms in time
