Abstract

The invention discloses a circuit for continuously and dynamically measuring a joint movement angle, which comprises a Bluetooth WIFI main control module, a nine-axis inertial sensor module, a voltage stabilizing circuit module and a power supply input module. The Bluetooth WIFI main control module is in communication connection with the nine-axis inertial sensor module through an I2C bus; the voltage stabilizing circuit module is connected with the power supply input module, and the output of the voltage stabilizing circuit module is connected with the power supplies of the Bluetooth WIFI main control module, the low-speed high-precision magnetometer and the high-speed low-precision magnetometer; the nine-axis inertial sensor module comprises a sensor chip, a low-speed high-precision magnetometer and a high-speed low-precision magnetometer; and the Bluetooth WIFI main control module comprises a main control chip. According to the circuit for continuously and dynamically measuring the joint motion angle, two circuits for measuring the joint composite motion angle can be conveniently bound to limbs on the two sides of a joint, and therefore information collection is conducted on different devices through a nine-axis inertial sensor.

Description

Technical field [0001] The present invention relates to the field of joint equipment information acquisition technology, and is specifically a circuit and method thereof for continuous dynamic measurement of joint activity angles. Background technique [0002] The method of measurement angle in the prior art is the angle of using a sensor measured on a single limb, and the angle obtained is relative to absolute level, the angle of vertical, the angle of the other limbs, needs to be used in the measurement joint activity angle A limb is placed in an absolute position, which has certain limitations. When the action of the joint is a composite motion, such as the limbs connected to the joint, in this case, there is a defect in the prior art, and it is impossible to measure. Inventive content [0003] It is an object of the present invention to provide a circuit and a process of continuous dynamic measurement joint activity angles to solve the above inconvenience to make information...
