Abstract

The invention belongs to the field of signal analysis and data processing, and discloses an equipment vibration early warning method and system based on low-delay data smoothing, and the method comprises the steps: obtaining the current vibration data of equipment and a first preset number of vibration data before the current vibration data, and judging whether the current vibration data meets a preset cliff type descending condition or not; if yes, taking the current vibration data as smooth data of the current vibration data; otherwise, through a preset first weight sequence, calculating a weighted average value of the current vibration data and the first preset number of vibration data to obtain a first average value; through a preset second weight sequence, calculating a weighted average value of the current vibration data and a second preset number of previous vibration data to obtain a second average value; and obtaining smooth data of the current vibration data according to the first average value and the second average value, and carrying out equipment vibration early warning according to the smooth data. False alarm and missing alarm caused by the hysteresis effect of vibration data smoothing are avoided.

Description

technical field [0001] The invention belongs to the field of signal analysis and data processing, and relates to a device vibration early warning method and system based on low-delay data smoothing. Background technique [0002] In recent years, vibration on-line monitoring technology has become more and more widely used in industrial sites. Almost all key equipment on site is equipped with vibration sensors to monitor equipment status. At present, the vibration characteristic parameters obtained by online vibration monitoring are extracted from the original collected vibration data, and the current vibration characteristics are not calibrated and statistically processed according to the results of historical vibration data. A single real-time vibration data may be affected by the acquisition conditions or the interference of various factors on site. Therefore, smoothing and calibrating the current vibration data through the vibration data collected many times in the past ha...
