Abstract

An angle sensor for leg angle measurement is disclosed and belongs to the field of an angle sensor. The angle sensor includes a first circuit board for generating a first angle signal and a first temperature signal at the thigh and transmitting the first angle signal and the first temperature signal to the single chip microcomputer, a second circuit board for generating a second angle signal and asecond temperature signal at the lower leg and transmitting the second angle signal and the second temperature signal to a single chip microcomputer, and the single chip microcomputer for processingthe first angle signal, the second angle signal, the first temperature signal and the second temperature signal to obtain a final angle value of the single chip microcomputer. It solves the problems of inaccurate observation of angle change of leg shape by naked eyes, interference of ambient temperature and strong magnetic field in leg shape correction, dance training and rehabilitation treatment,and can be used in leg shape correction, dance training and rehabilitation treatment.

Description

technical field [0001] The invention provides an angle sensor for leg angle measurement, which belongs to the field of angle sensors. Background technique [0002] Existing angle sensors, such as contact potentiometers, calculate the corresponding movement of the rotating shaft by detecting the voltage change in the circuit caused by the sliding of the potentiometer connected to the rotating shaft. The principle is simple, but the precision of the potentiometer will decrease or even fail completely after the resistance body is worn out after a long period of sliding friction. In addition, there is another situation that is a magnetic position sensor, which uses the rotation of a permanent magnet to generate a rotating magnetic field, and then detects the direction of the magnetic field through a magnetic position sensor chip, thereby detecting the rotation angle. However, there is also a problem with this structure. The magnetic position sensor chip cannot work in a strong ...
