With the large-scale increase of industrial equipment monitoring nodes and the improvement of monitoring duration,how to effectively monitor large-scale vibration signals has become an urgent problem to be solved.Therefore,a vibration monitoring system for industrial equipment based on Micro Electro-Mechanical System(MEMS)technology has been proposed in the study.The terminal of the monitoring system is designed through the accelerometer and hash algorithm of MEMS,and the system program is developed combined with edge computing.Verification shows that the frequency domain of the proposed system vibration signal has increased by 4.49%compared to the data acquisition card of Donghua DH5981 model,and the hash code calculated by the proposed monitoring system is consistent with the actual vibration signal.The consistency rate between the monitoring and evaluation results of multiple signals and the actual results is as high as 100%.The results indicate that the industrial equipment vibration monitoring system based on the proposed MEMS is feasible and effective in large-scale vibration signal monitoring.The use of MEMS for vibration signal acquisition,combined with hash algorithm for signal processing and calculation,has positive practical significance in vibration signal monitoring of industrial equipment.
