Self-heating lower garment and method for tumble detection fused with transfer learning algorithm

Abstract

The invention provides a self-heating lower garment for tumble detection fused with a transfer learning algorithm. The self-heating lower garment comprises trousers, a tumble detection sensor capable of detecting motion data of a user, and an air pressure detection sensor, wherein the motion data comprises acceleration, Euler angle, and angular velocity; and the air pressure detection sensor can detect the height difference when the user tumbles. According to the self-heating lower garment and method for tumble detection fused with the transfer learning algorithm, the detection device is arranged in the trousers to directly detect the lower limb movement behavior of a user, the invention further provides the method for tumble detection fused with the transfer learning algorithm, movement data collection and tumble behavior result collection are performed on the user, and a training model is constructed. The movement data of the user can be collected in real time through a training model, then the tumble detection result of the user is obtained, the movement behavior of the user can be monitored and fed back in real time, and the responsivity is high.

Description

technical field [0001] The invention relates to the technical field of behavior detection, in particular to a self-heating download and method for fall detection fused with transfer learning algorithms. Background technique [0002] As the population ages, more and more tragedies occur due to accidental falls, and falls have become a major public health problem worldwide. It is worth noting that falls may cause fatal or non-fatal injuries, and most falls will not directly cause fatal consequences, but in the elderly, due to the aging of the body, subsequent injuries caused by some non-fatal injuries will have more serious consequences, even die. Therefore, it is particularly important to provide timely treatment for the elderly who have fallen. [0003] At present, most of the wearable fall detection devices use the upper coat as the carrier, and the fall detectors are mostly placed on the chest, cuff of the upper coat or worn in the form of a necklace. The use effect of ...

AI Technical Summary

Problems solved by technology

The use effect of wearable fall detectors is often quite different from the experimental results. The algorithm obtained through experiments cannot be applied to people of different heights and weights, the accuracy has declined, the universality is low, and the wearing comfort is still a problem. To be solved, in order to solve this problem, it is necessary to develop a wearable device with fall detection function
