Title:
METHOD FOR DETERMINING DEVICE MOVEMENT ABNORMALITY, AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/057635
Kind Code:
A1
Abstract:
A method for determining device movement abnormality and a system. The method comprises: step S1, acquiring acceleration data of a device moving in a preset direction, filtering the acquired acceleration data, and discarding data of the device being in a static state; step S21, generating, according to the acceleration data, an acceleration curve in the preset direction, and capturing an acceleration curve of a movement action; step S22, dividing the acceleration curve into multiple segments according to each slope change and acceleration direction change of the acceleration curve; and step S23, determining, according to acceleration features characterized by the respective segments of the acceleration curve, whether device movement is abnormal. The method enables acquisition of acceleration data of a device according to a movement condition thereof, and subsequently determines, according to the acceleration data, whether device movement is abnormal, thereby achieving device failure determination, and allowing discovery of abnormal conditions that might cause device failure, and effectively protecting use safety of devices.
