Tumble detection method and device

Abstract

The invention discloses a tumble detection method and device. A first pressure signal, a second pressure signal and a third pressure signal are acquired in real time through a first pressure sensor arranged on the inner side of a shoe sole, a second pressure sensor arranged on the inner side of a shoe rear side part, and a third pressure sensor arranged on the inner side of a shoe heel part respectively; if the duration time of the acquired first pressure signal, second pressure signal and third pressure signal meeting the following conditions reaches a preset time threshold value: the first pressure signal is smaller than a first preset threshold value, or the second pressure signal is larger than a second preset threshold value, or the third pressure signal is larger than a third preset threshold value, it is judged that a tumble happens; a tumble alarm signal is given out under the condition that it is judged that the tumble happens. The tumble can be accurately detected, the implementation method is simple, and cost is low.

Description

technical field [0001] The invention relates to the field of smart shoes, in particular to a fall detection method and a fall detection device. Background technique [0002] According to relevant statistics, falls are currently the most common accident among children, accounting for 44% of all children's accidents; falls have also become one of the important causes of accidental disability and death for the elderly over 65 years old. When a fall accident occurs, if the faller is not treated in time, the delay in injury will cause a great threat to his health, and for patients with cardiovascular and cerebrovascular diseases and high blood pressure, the possibility of death may even occur . Therefore, it is crucial to perform fall detection in potential high-risk groups for falls. [0003] In order to detect fall events, measures for detection of fall events have been proposed. For example: a three-axis acceleration sensor, an angular velocity sensor and a pressure sensor ...

AI Technical Summary

Problems solved by technology

However, this method uses a high-cost triaxial acceleration sensor and an angular velocity sensor to detect the user's fall state, which makes it costly to implement. At the same time, there are many types of sensing data obtained through the triaxial acceleration sensor, angular velocity sensor and pressure sensor. This leads to a complex process of data processing in the fall detection method
