Problems solved by technology

[0006] For this reason, the first purpose of the present invention is to propose a method for processing measurement data, which solves the problem that the time series conversion algorithm in the prior art has too few features and information provided by time series segments after reducing the dimension of the time series, resulting in Motif discovery is inaccurate, which leads to technical problems of poor behavior recognition effect

Abstract

The invention provides a processing method and a device for measuring data, wherein the method comprises: according to the measurement data of each measurement time point, Generate original sequence,dividing the original sequence into multiple time snippets, For each time segment, according to the measured data of the measured time points in the time slice, The symbolic vector of the time segmentis obtained by extracting various features from each dimensional series of the time segment. The symbolic vector generated according to the symbolic vector of the time segment is processed by the modal discovery algorithm. The invention solves the technical problem that after the timing conversion algorithm in the prior art reduces the dimension of the timing sequence, the features and information provided by the timing sequence segments are too little to cause the inaccurate discovery of the motif, thereby leading to poor behavior recognition effect.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a method and device for processing measurement data. Background technique [0002] With the popularization and improvement of mobile computing, network and sensor technology, identifying and tracking human activities has become an important application in the wearable field. Establish a human health map by tracking human behavior, and human behavior recognition includes independent behavior recognition and discovery such as sitting, standing, walking, running, cycling, and driving, as well as switching between various behavior states over a long period of time. [0003] The recognition of human behavior is based on the analysis and extraction of the measured sequence. The sequence here refers to an ordered data list formed over time, which reflects the state of a certain transaction / event over time. Status can be represented by real values ​​or symbols. [0004] In the prior ar...
