Abstract

The invention discloses a road condition recognition system for above-knee prostheses. The system comprises prosthetic knee joints, prosthetic shank tubes and false feet and is characterized in that the system further comprises heel photoelectric sensor modules, tiptoe photoelectric sensor modules, gyroscope modules, a single-chip microcomputer module and a drive motor module. Compared with the prior art, according to the road condition recognition system, on the basis of an existing power type prosthesis technology, the gyroscope modules are installed on the prosthetic shank tubes, the photoelectric sensor modules are installed on the false tiptoes and the heels, a road condition information collection module is built, and the defect that a timely road condition recognition method is lacking in the prior art is overcome. Various pieces of detected sensor information are processed through the single-chip microcomputer, the six road conditions of flat floor / uphill / downhill / going upstairs / going downstairs / barriers can be accurately recognized in time, the prostheses of a patient can be controlled according to different road conditions, and the patient can easily complete the daily activities of going upstairs, climbing slopes, stepping over the barriers and the like.

Description

technical field [0001] The invention relates to human lower limb prosthesis technology, in particular to a road condition recognition system for an above-knee prosthesis, which can identify six different road conditions of flat ground / uphill / downhill / upstairs / down stairs / obstacles, and then recognize the knee joint prosthesis Corresponding control is carried out to make the walking process of the disabled safer while reducing the burden of the disabled. Background technique [0002] For lower-limb amputees, especially above-knee amputees, fitting a prosthetic is the only way for the disabled person to return to daily life. The types of prostheses currently entering the market, from the initial "passive" prosthetics, such as simple mechanical devices, linkages (mostly four-bar linkages), pneumatic or hydraulic devices, and computer intelligent control devices, to the later inventions have increased An "active" prosthesis with a power device, such as an "active human leg pros...
