Detection device and detection method for human motion information

Abstract

The invention discloses a detection device and a detection method for human motion information, belonging to the field of electronic information and mode identification. The detection device and the detection method of the human motion information are based on a single triaxial accelerometer and a Zigbee module; the detection method is based on a gait recognition technology and a statistical data modeling and can achieve detection of the human motion information by the triaxial accelerometer; the detection device comprises wireless sensing comprehensive modules arranged on a pair of shoes and an upper computer receiving module connected with a PC (Personal Computer) terminal; the device uses a trigger mode to perform wireless transmission for motion data in order to perform a human-computer interaction; due to a Zigbee low-power consumption design, a system can use batteries with smaller volume and capacity to reduce weight and volume of the whole system so as to be beneficial to be put at the bottom of the shoes; due to a voltage-stabilizing power supply design, an error of a quantized acceleration magnitude of an accelerometer after a working voltage drops can be avoided when the batteries are powered.

Description

technical field [0001] The invention relates to a human body motion information detection device and a detection method based on a sensor and electronic communication technology, belonging to the field of electronic information and pattern recognition. Background technique [0002] Smart sports shoes are a cross product of information technology and traditional footwear industry. The smart sports shoes currently on the market include Nike's nike+ and Adidas' micoach. Among them, nike+ series sports shoes adopt piezoelectric induction technology, realize running counting and mileage estimation through its patented technology, and transmit human body movement data to Apple's smart terminals through wireless transmission technology in real time, such as IPOD, IPHONE etc.; Adidas' micoach smart sports shoes adopt the technology of VTI Technology Co., Ltd., based on the built-in accelerometer, combined with its correction technology, it can measure acceleration, speed and runnin...

AI Technical Summary

Problems solved by technology

The accelerometer alone cannot restore the true orientation of the acceleration in space, and of course it is impossible to measure the "spatial position";

[0005] 2. Its so-called "can design the placement position according to the shoes with different functions in the actual application" is a huge flaw in the calculation of the "spatial position", because if the placement position of the accelerometer is arbitrary, for example, the so-called "spatial position" Sensor" is tied to the shoelace, then the reference position of the accelerometer is uncertain (it will shake violently during the movement, resulting in attitude changes

For the key technology of wireless communication, the so-called use of WIFI and communication technology in the field of telecommunications in some patent documents is completely unfeasible, because the current power consumption of WIFI and communication technology in the field of telecommunications is too large
