Abstract

The invention discloses a wireless vibration monitoring method, electronic equipment and a storage medium, and the method comprises the steps: collecting a group of short-waveform vibration signals S containing all signal characteristics at a high sampling rate in a detection period T1, obtaining a vibration effective value VBrms and a speed effective value Vrms, obtaining the energy El, Em and Eh corresponding to a low-frequency band, a middle-frequency band and a high-frequency band of the signal S, and obtaining the energy El, Em and Eh of the signal S; respectively comparing with the energy thresholds Thl, Thm and Thh of the corresponding frequency bands, and formulating corresponding sampling strategies; if no fault alarm exists in the detection period T2, a group of long-waveform vibration signals is collected at a low sampling rate for state monitoring and fault diagnosis, and if one or more groups of alarms exist in the detection period T2, a group of long-waveform vibration signals is collected at the maximum alarm sampling frequency for state monitoring and fault diagnosis; the method has the advantages that sampling with the maximum sampling rate all the time is avoided through a dynamic sampling mode, and the system power consumption is effectively reduced.

Description

technical field [0001] The present invention relates to the field of signal detection and wireless communication, and more particularly to a wireless vibration monitoring method, electronic device and storage medium. Background technique [0002] Traditionally, the real-time monitoring of rotating and reciprocating equipment by wired data collectors, such as Chinese Patent Publication No. CN102589681A, discloses a wireless vibration measurement method and device for highly reliable state monitoring of rotating equipment, but wired data collectors have construction costs. high, signal attenuation and interference issues. To solve this problem, the data needs to be sent wirelessly to the receiver immediately after the measurement. The wireless data collector integrates sensors, memory and a processor with embedded RF functions, and is powered by batteries. In order to reduce the frequency of maintenance and replacement of batteries, under the premise of meeting the acquisitio...
