Abstract

A human body sitting posture detecting system based on a Zigbee acceleration sensing network and a human body sitting posture detecting method relate to human body sitting posture detecting system and detecting method, and aim to solve the problems of the conventional human body sitting posture detecting and correcting system such as low intelligent degree, and poor flexibility because people need to wear detecting and correcting equipment. In the detecting system, data acquired by a triaxial acceleration sensor is emitted to a Zigbee network through a Zigbee network emitter, a Zigbee network receiver receives the data and converts the data into an inclined angle through an upper computer, and a human body sitting posture detection result is obtained through judging the inclined angle based on a preset threshold. When the system is used, the triaxial acceleration sensor and the Zigbee network emitter are fixed on a to-be-detected human body and in the same height with shoulders, then the detection can be realized through the Zigbee network, and the intelligent degree is high; meanwhile, the triaxial acceleration sensor and the Zigbee network emitter are small in size and light in weight, so that the detecting system flexibility is high. The invention is suitable for human body sitting posture detection.

Description

technical field [0001] The invention relates to a human body sitting posture detection system and a detection method. Background technique [0002] With the development of information technology and the popularization of the Internet, more and more operation methods have changed from the previous manual operation to today's remote control. People can complete tasks such as instant message browsing, online shopping, remote control, etc. Monitor, communicate in different places, and complete assignments such as paper writing, graphics drawing, and scientific computing through personal PCs. In such an era of information explosion, whether it is various copywriters or young students, they have to work and study for a long time while using computers. As a result, symptoms such as hunchback, cervical spondylosis, frozen shoulder, dry eye, and myopia caused by incorrect sitting posture have brought more and more troubles to people. Therefore, it is an urgent problem to be solved ...
