A Study Of The Intelligent Prostheses' Controlling Source

The EMG signals are the major controlling source, the connection between the EMG signals and the human motions has a very important significance for the study of intelligent prostheses. The virtual instruments (VI) technique based on PC is the technique of a kind of newly arisen structure instrument; it organizes the instrument system by making use of strong calculation ability and abundant software & hardware resources of computers, and realizes the transition from the traditional instruments to the transitions of the calculator system. This thesis achieves a kind of new EMG to acquire, show, analyze method in view of the VI theory and builds up a development terrace for the research that the EMG controlling intelligent prostheses.First, this thesis introduces the characteristics and basic composition of the virtual instruments and data acquisition technique; Then to give a detailed introduction to the characteristics of EMG. The hardware compositions of EMG acquisition system are showed in the 4th chapters, the methods of filtration and dislodging 50Hz disturbance are special focused on. In the 5th chapters the thesis give the software thinking and methods, it use VC++6.0 to complete the design to the software.The research job have a innovation viewpoint that it belongs together the VI conception and EMG acquisition systems and builds a set of intelligent EMG acquisitions and analyses system on the account of PC.
