Artificial hand simulation 人工手仿真
It is designed and built using air core inductors to avoid saturation at peak current loads . the unit comprises an artificial hand simulation 本儀器包含ansic 6 . 3 . 4要求的人工手仿真和一個可選擇性使用的仿真網(wǎng)路50 50 。
Artificial hand with myoelectrical control is a new type of dynamic artificial hand and the model " man - machine system " that controlled by biological electricity 肌電控制假手是利用肌電作為控制信號的新型動力假手,是一種生物電控制的典型“人?機系統(tǒng)” 。
Artificial hand with myoelectrical control can reflect sport information of limbs via simply control . compared with other control ways , it has a lot of superiority . by this reason , it is favored by patient and has wide markets , and now it has became a focus in studying of artificial limbs 肌電假手能夠反映人肢體的運動信息,控制簡單,與其它方式控制的假手比起來具有很多的優(yōu)越性,因而受到患者的青睞,擁有廣闊的市場,而且也成為上肢假肢研究中的一個熱點。
By utilizing the knowledge of digital circuit and simulation circuit , the system designs the pretreatment dealing circuit of the myoelectrical signal , which has the feature of big input impedance well suppress of public module and high gains . then the signal is gathered with " zhentong " data gathering after dealing with , and the software of signal processing is explored before the myoelectric signal is analyzed . after picking up eigenvalue , it is proved that the result is unanimous basically with the data of the relevant materials ; the other is to control artificial hand by the eigenvalue of the myoelectric signa l and at last the system gets very good control results 即利用數(shù)字電路和模擬電路等相關(guān)知識,設(shè)計了具有輸入阻抗大、共模抑制好、增益高等特點的肌電信號前置處理電路,利用“振通”數(shù)據(jù)采集儀對處理后的信號進行采集,并利用快速傅立葉變換的相關(guān)知識編寫了信號處理程序,對肌電信號進行了波形分析、幅值譜分析和功率譜分析,提取了信號特征值,與相關(guān)資料的數(shù)據(jù)相比,基本一致;二是利用肌電信號的特征值對肌電假手進行控制。
