Embodiment Construction

[0078] Attached below Figure 1~8 The present invention is described in detail:

[0079] figure 1 The work flow diagram of the device for filtering abnormal data is shown. The data stream (arrived by time) is a collection of data that needs to be filtered by outliers, and the configuration interface for filtering outliers provides parameter information for the algorithm of the present invention:

[0080] WS---window size (positive integer);

[0081] K---judging whether the data in the window is stable (non-negative);

[0082] D---judging whether the data needs to be filtered (integer);

[0083] ReCalc---judging whether the R value in the window needs to be recalculated (integer);

[0084] Filter abnormal data according to the provided parameter information. If the user is satisfied with the filtering result, the filtering process ends; otherwise, the user provides parameter information again according to the output result, thus entering a new round of feedback.

Abstract

The invention relates to a real-time signal processing method of a data acquisition instrument and belongs to an exceptional data filtering processing method. The method provided by the invention mainly comprises the following steps: (1) providing a user with an interface for interaction; (2) returning an exceptional data filtering result according to information fed back by the user, if the result is not satisfactory to the user, modifying the fed back information at the interacting interface; (3) after acquiring the feedback result of the user, re-filtering the exceptional value of data; (4) updating the exceptional data filtering result; (5) returning to (2) or ending. The process can be repeated till the user is satisfied with the processing result.

Description

technical field [0001] The invention relates to a real-time signal processing method of a data acquisition instrument, which belongs to a processing method for filtering abnormal data. Background technique [0002] With the wide application of data acquisition instruments in different fields, effective management and utilization of these collected data has become a very meaningful and challenging task. The data collected by the data acquisition instrument can usually be regarded as a continuous discrete data sequence in time. When the equipment is normal, the data is stable, but when the equipment is disturbed by the external environment, the collected data is abnormal or distorted. How to find an effective algorithm to weaken external interference factors, eliminate outliers, and ensure the authenticity of data is a meaningful and challenging task. At the same time, because each user has different identification standards for outliers, the current abnormal data processing ...
