Flexible sensor-based human body sitting posture recognition method and human body sitting posture recognition system

Abstract

The invention discloses a flexible sensor-based human body sitting posture recognition method. According to the invention, firstly, the bending data of the back of a user are collected, and the bending data are preprocessed and extracted. Secondly, feature vectors are recognized by utilizing a well trained error back propagation type artificial neural network, and then a recognition result is obtained. Thirdly, the recognition result is transmitted to the intelligent terminal of a user. According to a flexible sensor-based human body sitting posture recognition system provided in the invention, the bending data of the back of the user are detected by a flexible sensor. Meanwhile, the processed bending data are recognized by utilizing a classification and recognition unit provided with theerror back propagation type artificial neural network. In this way, a final recognition result can be obtained. Moreover, the recognition result is transmitted to the intelligent terminal of the userthrough a wireless communication unit. Since the detection is carried out by the flexible sensor, the system is simple in structure and convenient in detection.

Description

technical field [0001] The invention relates to the application field of sensor technology, in particular to a flexible sensor-based human sitting posture recognition method and system thereof. Background technique [0002] Sitting posture is the state where students and office workers spend most of their time, and bad sitting posture will have a great impact on people's health. Teenagers often fail to pay attention to maintaining correct posture in their studies and lives. And parents and teachers can't remind them all the time, myopia and hunchback will form over time; for office workers, with the accelerated pace of life and increasing work pressure, more and more adults need to work for a long time Facing the computer, improper sitting posture often causes symptoms such as occupational musculoskeletal disorders and low back pain. The negative impact of bad sitting posture on health will not only seriously affect the physical and mental health of patients and work ability...
