Thinned Vibration Waveform Display with Data Distinction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for displaying thinned vibration waveform data struggle to clearly differentiate between original and representative data, and often fail to provide smooth transitions between these data types, making it difficult for analysts to interpret the data effectively.
Innovation Solution
The proposed system graphically displays thinned time waveforms by leaving blank gaps in regions where the waveform has been thinned, or by plotting original waveform blocks with reference blocks of data in between, using different colors and line types to distinguish between original and representative data. Additionally, smoothing algorithms, such as polynomial fits, are used to smooth intersections between original and representative waveform blocks.

1Quantity of substance
If waveform data is thinned by creating blocks of representative data, then storage space is reduced, but it becomes difficult to distinguish between original and representative data in graphical displays
Solution Approach 1:
The patent applies different colors to represent different data types in the graphical display. Original waveform blocks are displayed in one color while representative waveform blocks are displayed in another color, enabling clear visual distinction between actual measured data and synthesized representative data, thus resolving the information distinction problem while maintaining storage efficiency
Solution Approach 2:
The waveform data is segmented into distinct blocks - original waveform blocks and representative waveform blocks - which are then displayed separately with visual markers. This segmentation allows the system to maintain reduced storage while providing clear visual identification of data types through the graphical interface
2Stability of the object's composition
If representative data blocks are plotted between original waveform blocks, then continuous visualization is achieved, but discontinuities and rough transitions occur at intersection points
Solution Approach 1:
The patent applies smoothing algorithms to the waveform data blocks before displaying them. By pre-processing the data to smooth out discontinuities at the boundaries between original and representative blocks, the system achieves continuous visual representation without rough transitions, resolving both the continuity and smoothness requirements
Solution Approach 2:
The patent modifies the waveform data parameters by applying smoothing algorithms that adjust the amplitude and phase values at block boundaries. This parameter transformation eliminates abrupt transitions and creates smooth, continuous visual representation across the entire waveform display

AI summary
A vibration data collection device monitors vibration of a machine, generates original machine vibration waveform data based on the monitored vibration, and removes portions of the original machine vibration waveform data that do not indicate an occurrence of a vibration event related to a potential fault in the machine. The vibration data collection device then stores thinned waveform data that includes blocks of the original machine vibration waveform data and excludes the portions that have been removed. A data analysis computer generates a thinned waveform plot based on the thinned waveform data. In some embodiments, the thinned waveform plot includes the blocks of original machine vibration waveform data separated in time by gaps representing the portions that have been removed. In some embodiments, the thinned waveform plot that includes the blocks of the original machine vibration waveform data and representative blocks of data that each represent the portions of the original machine vibration waveform data that have been removed. A display device displays the thinned waveform plot for viewing by an analyst.
