Following notebook computer being used broadly in field detectiong, peripheral which have usb interface are prepotent more and more. the ultrasonc flaw detector we ' re designing will be connect with notebook computer in field detection, so we elect usb interface to accomplish transmission between detector and pc. the article not only introduces basic knowledge about usb briefly and gives detailed develop process of usb peripheral and flow diagrams of usb controller, but also operating against our device ' s functions, gives develop process of device driver and important api function being used. in addition, an exclusive interface being used to control and display is designed
我們所設計的探傷儀外置盒在現場作業時是與筆記本電腦相連接的，因此選用usb介面來實現數據在探傷儀外置盒與pc機間的傳輸。這里簡單的介紹了有關usb介面的基礎知識，給出了探傷儀usb介面的詳細開發過程及usb控制器的程序流程圖，並且針對于本儀器要實現的功能，給出了pc機端的設備驅動程序開發過程及關鍵的api函數調用程序。此外這里還設計了一個專用的控制及顯示界面。Ab stract the author is engaged in the studying and manufacturing of an intelligent, capable and portable, multifuctional electrocardio monitoring equipment with aduc8 12 single - chip. microcomputer. the equipment can gather and record the electrocardio signals automatically, also can analyse it at real time, and send it out to the monitoring center through the telephone at real time or send it out by serial interfaces to computer. it use the graph display device to show the electrocardio waves and menu. cooperated with buttons, it provides amicable interface, and makes operation simple and convenient. based on the feature of the electrocardio signals, this paper also proposes a electrocardio distortionless data compression algorithm. the algorithn is simple but effective, it can process the data at real time, and the compression - ratio reaches 2 6
所研製的監護儀能長時間採集和記錄心電信號，同時可進行心電數據的實時分析，並可通過電話向監護中心實時發送，也可通過串列介面發送至微機。該監護儀採用圖形液晶顯示器顯示心電波形和菜單，配合按鍵提供友好的人機界面，操作簡潔。本文還根據心電波形的特徵，提出一種心電數據的無損壓縮演算法，該演算法簡單有效，能實時實現，壓縮比達到2 6倍。
