【摘要】：表面肌電是指收縮肌肉時產(chǎn)生的電信號,從人體皮膚表面測得。表面肌電能夠反映人的生理狀態(tài)信息,應用背景主要集中在康復醫(yī)學和體育科學兩大領域,具有很大的實用價值,例如應用在肌電控制假肢、肌電刺激治療肌肉萎縮、診斷肌肉力量和肌肉疲勞等方面。隨著社會經(jīng)濟的發(fā)展,人民的生活水平在不斷地提高,科學技術(shù)在不斷地進步,人們要求有更好的醫(yī)療器械。電子等相關科學技術(shù)在醫(yī)療器械方面的應用提高了醫(yī)療器械的性能,電子醫(yī)療保健產(chǎn)品變得小型化、智能化、信息化。醫(yī)療器械的功能越來越多,成本越來越低。許多疾病的檢測和診斷都與電生理信號密切相關,國內(nèi)外學者都在研究其相關算法與應用,研究前景廣闊。 本文設計一個表面肌電檢測與訓練系統(tǒng)的移動端,它能夠在脫離電腦的情況下對表面肌電信號進行實時采集、顯示、儲存等。它能夠通過無線WIFI(wireless fidelity)和有線USB(Universal Serial Bus)將采集到的肌電信號實時地傳輸?shù)诫娔X上。某些時候表面肌電需要移動測量,所以設計一個可移動的小型終端是很有必要的。 系統(tǒng)設計分為硬件部分設計和軟件部分設計。 系統(tǒng)硬件部分設計分為模擬部分和數(shù)字部分：模擬部分有前端采集放大器、主放大器,模擬信號通過轉(zhuǎn)換成16位AD(Analog Digital)傳輸?shù)綌?shù)字板；數(shù)字部分電路采用以ARM7為核心的多功能板。醫(yī)療器械關系到人民群眾的生命健康和安全,硬件部分設計關注了電壓隔離等方面內(nèi)容。論文描述高質(zhì)量的供電電源的設計,高質(zhì)量的供電電源能提高采樣質(zhì)量。論文描述放大電路的設計,電路的設計根據(jù)表面肌電的特點采用合適的濾波器。論文分析幾種硬件設備的差別并為系統(tǒng)選擇合適的硬件。 系統(tǒng)軟件部分設計采用UCOS(UC Operating System)和UCGUI(UC GraphicalUser Interface),有采集、觸摸屏顯示、儲存、回放記錄、校正放大倍數(shù)等模塊。觸摸屏和全鍵盤拼音輸入法使得機器操作方便簡單,人機互動界面友好。采集功能模塊是移動終端系統(tǒng)的重要部分,它采用SPI接口控制AD采樣,數(shù)字信號的濾波采用梳狀濾波器,采集功能模塊的界面使用UCGUI對話框。論文分析嵌入式拼音輸入法并設計輸入法界面。論文分析USB驅(qū)動程序并設計USB狀態(tài)機。 測試結(jié)果表明該移動終端性能好,操作方便,體積小,成本低,市場前景好。該移動終端不僅可以應用到三甲醫(yī)院,還可以廣泛普及到社區(qū)醫(yī)院,甚至普及到家庭,使用戶可以更方便地以更低成本獲得康復治療,社會效益重大,經(jīng)濟效益顯著。 最后對論文進行總結(jié)。該移動終端存在很多不足的地方,移動終端使用的無線網(wǎng)絡是WIFI網(wǎng)絡,所以該移動終端的移動范圍不夠大。論文最后提出解決思路,該設備可以通過移動通信網(wǎng)絡傳輸測量數(shù)據(jù),這樣就提高了移動終端的信息化水平。移動醫(yī)療發(fā)展前景廣闊。
[Abstract]:Surface electromyography refers to electrical signals generated when muscles are contracted, measured from human skin surfaces. Surface electromyography can reflect human physiological state information. The application background is mainly in the two major fields of rehabilitation medicine and sports science. Of great practical value, for example, in the control of prostheses by electromyography, in the treatment of muscular atrophy by myoelectric stimulation, in the diagnosis of muscle strength and muscle fatigue, etc. With the development of society and economy, the standard of living of the people continues to improve. With the development of science and technology, people demand better medical devices. The application of electronic science and technology in medical devices has improved the performance of medical devices, and electronic medical care products have become miniaturized and intelligent. The function of medical device is more and more and the cost is lower and lower. The detection and diagnosis of many diseases are closely related to the electrophysiological signal, and scholars at home and abroad are studying its related algorithm and application, and the research prospect is broad. In this paper, a moving end of surface electromyography detection and training system is designed, which can collect and display surface EMG signals in real time without computer. It can transmit the collected EMG signals to the computer in real time via wireless WIFI(wireless fiduciity) and wired USB(Universal Serial Bus. at some times, the surface electromyography needs moving measurement, so it is necessary to design a small mobile terminal. The system design is divided into hardware part design and software part design. The hardware part of the system is divided into analog part and digital part: the analog part has a front-end acquisition amplifier, a main amplifier, and the analog signal is transmitted to the digital board by converting the analog signal into a 16-bit AD(Analog digital board. The digital circuit adopts the multifunctional board with ARM7 as the core. The medical device is related to the people's life, health and safety, and the hardware design pays close attention to the voltage isolation and so on. The paper describes the design of the high quality power supply. The high quality power supply can improve the sampling quality. This paper describes the design of amplifying circuit, which adopts the appropriate filter according to the characteristics of surface electromyography. The paper analyzes the differences of several kinds of hardware devices and selects the appropriate hardware for the system. The software design of the system adopts UCOS(UC Operating system and UCGUI(UC GraphicalUser Interface, and has modules such as acquisition, touch screen display, storage, playback record, correction of magnification, etc. The touch screen and the whole keyboard Pinyin input method make the operation of the machine convenient and simple. The acquisition function module is an important part of the mobile terminal system. It uses SPI interface to control AD sampling, and the digital signal filter adopts comb filter. The interface of the collection function module uses UCGUI dialog box. The paper analyzes the embedded Pinyin input method and designs the input method interface. The paper analyzes the USB driver and designs the USB state machine. The test results show that the mobile terminal has good performance, convenient operation, small size, low cost and good market prospect. The mobile terminal can be applied not only to the third Class A Hospital, but also to community hospitals and even families. It makes it more convenient for users to obtain rehabilitation treatment at lower cost, which has great social benefits and remarkable economic benefits. Finally, the paper summarizes the mobile terminal. There are many shortcomings in the mobile terminal. The wireless network used by the mobile terminal is WIFI network, so the mobile range of the mobile terminal is not large enough. This device can transmit the measurement data through the mobile communication network, thus improving the level of information of mobile terminal, and the development prospect of mobile medical treatment is broad.
