Embodiment Construction
[0031] Specific embodiments of the present invention are given below, and the specific embodiments are only used to further describe the present invention in detail, and do not limit the protection scope of the claims of the present application.
[0032] The invention provides an intelligent knee prosthesis wearer's riding state recognition system such as figure 1 As shown, including the main structure of the prosthesis and the recognition system. The main structure of the prosthesis consists of a prosthetic socket 1, a prosthetic knee joint 2, a prosthetic calf tube 3, and a prosthetic foot 4. The structure is that the bottom of the prosthetic socket 1 is connected to the prosthetic knee joint 2, and the bottom of the prosthetic knee joint 2 is connected to the upper end of the prosthetic calf tube 3. , the lower end of the prosthetic calf tube 3 is connected to the prosthetic foot 4 .
[0033] The devices in the main body structure of the prosthesis are all current known te...

The invention discloses an intelligent system for identifying the riding state of an above-knee prosthesis wearer. The system comprises a prosthesis body structure and an identifying system; the prosthesis body structure comprises a prosthesis accepting cavity, a prosthesis knee joint, a prosthesis crus tube and a prosthesis foot, wherein the bottom of the prosthesis accepting cavity is connectedwith the prosthesis knee joint, the bottom of the prosthesis knee joint is connected with the upper end of the prosthesis crus tube, and the lower end of the prosthesis crus tube is connected with theprosthesis foot; the identifying system comprises a prosthesis-accepting-cavity angle module, a prosthesis crus module, a tiptoe pressure sensor module, a foot-underside pressure sensor module, a heel pressure sensor module, a single chip microcomputer module and a driving motor module. According to the intelligent system for identifying the riding state of the above-knee prosthesis wearer, the judgment accuracy and the calculating speed of a knee-joint angle are greatly increased; judgment is conducted through the multiple sensors, and the judgment accuracy of the riding state is greatly improved.
Description
technical field [0001] The invention belongs to the technical field of artificial limbs, in particular to an above-knee artificial limb movement state recognition system, which can identify the riding movement state of the wearer of the artificial limb, and then control the knee joint of the artificial limb to improve the smoothness of the wearer of the artificial limb when riding safety, security and stability. Background technique [0002] Due to natural disasters, traffic accidents and other reasons, there are more and more lower limb above-knee amputees, and prosthetics have become the only device for amputees to restore normal movement. mostly. However, passive prosthetics cannot help the disabled to move actively, and will increase the metabolic energy of the disabled, and even cause safety hazards. Cycling as a lower-limb prosthetic activity, in a survey of 500 lower-limb amputees, 240 said they preferred to do sports such as cycling after amputation, and 250 said t...
