摘要

#$%^&*AU2020101929A420201001.pdf#####ABSTRACT The invention discloses an angle sensing system of exoskeleton device for lower limb rehabilitation training, comprising a data acquisition module, an A/D sampling processing module, and a main control module, wherein the data acquisition module comprises a magnetoresistive chip and a Hall element; the magnetoresistive chip adopts HMC1512, and the magnetoresistive chip is provided with eight, and the four magnetoresistive chips are a set of bridge circuits; the A/D sampling processing module comprises an amplifying arithmetic unit, a low-pass filter circuit, a buffer, and an A/D converter; the main control module comprises a TMS320F2812 main controller, an industrial personal computer (IPC), and an LCD screen. The angle sensing system of the invention can not only display real-time data, but also realize functions such as data storage and playback. It can guide the limbs to do various designated repetitive rehabilitation training through the machine, and assist the patient's lower limbs to restore the motor functions. Different rehabilitation programs can be customized according to the patient's own situation to meet the requirements of completeness and comfort of rehabilitation training for lower limb patients. 1DRAWINGS Magnetoresistive Hall Element Chip Amplifying Arithmetic Unit Low-Pass Filter Circuit Buffer A/D Converter -s1 Dial Part TMS320F2812 LCD Screen Main Controller Digital Display Part IPC FIG. 1 1
