Embodiment

[0053] An anti-jitter correction method for fan monitoring, comprising the following steps:

[0054] Step S1: Obtain a data stream f(k) (here the data stream is the original data, which can be divided into current epoch data and historical epoch data in chronological order), where k=0, 1, 2...Q; real-time data And send them in time sequence; use the window with the length value of L to intercept the data stream to obtain the intercepted data, and the intercepted data includes the current epoch data and the historical epoch data, specifically: {f(k)|k=Q} represents the current epoch {f(k)|0≤k<Q} represents the data of historical epochs, and the epoch interval time in this embodiment is determined by hardware configuration parameters (the initial window length value in this embodiment is set to 1, and the window length The value of the value L determines the number of intercepted historical epoch data).

[0055]Step S2: Correct the intercepted data, and output the correction da...

Abstract

According to the fan monitoring anti-jitter correction method, a window with a length value is adjusted in a self-adaptive mode, data can be subjected to stabilization processing, correction data of all epochs of fan monitoring can be obtained, breakpoint recognition and data fault coping can be carried out, and the correction accuracy is improved. According to the method, a window length and sensitive threshold adaptive function and a data stabilization preprocessing function are added, the data are preprocessed, so that the corrected data meet subsequent processing conditions, and the sensitive threshold is set along with the standard deviation of the real-time data.

Description

technical field [0001] The invention relates to the field of fan monitoring, in particular to an anti-jitter correction method for fan monitoring. Background technique [0002] When performing real-time positioning measurement on rotating and moving objects (such as fans), due to the overall resonance or external force interference of the connecting equipment, the positioning data jitters around the real data. A stable threshold is set for early warning judgment. However, due to the real-time nature of equipment movement and the need for timely feedback of data, the data cannot be denoised through post-processing. [0003] To sum up, there is an urgent need for an anti-jitter correction method for fan monitoring to solve the problem of data jitter in the prior art. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a fan monitoring anti-jitter correction method to solve the problem of data jitter in the prior art, and the specific technic...
