In the following chapters, a 16 - channel experimental phased array ultrasonic testing system is thoroughly explained, including digital beam forming, low noise programmable amplification of received ultrasound signal, multi - channel hi - speed hi - precision data acquisition, hi - speed real - time processing of multi - channel ultrasound signal, and hi - speed data transfer based on pci bus. in addition, the frame of software system is built
本文詳細闡述了作者所獨立研製的16通道相控陣超聲檢測實驗系統,包括數字化超聲發射/接收波束形成、超聲信號的低噪聲程式控制放大、多通道高速高精度數據採集、多通道超聲信號高速實時處理、基於pci總線的高速數據傳輸等全部電路模塊的結構及工作原理,並說明了所編寫的底層軟體系統的框架。The usual way to solve this problem is to transform the original signal into " 0 ", " 1 " equally - distributing circuitry code type which is fit for the optical channel, and then transmit
解決該問題常用的方法是通過通道編碼將原始信號變換為「 0 」和「 1 」均勻分佈的適合光線通道傳輸的線路碼型,再送入光路進行傳輸。Telephone communication is the most widely employed ways of communication in the world. telephone communication is becoming more and more important as the national economic reform deepens. dynamic channel borrowing assignment mode is an effective method in communication channel expansion. although it has been put into practical use in satellite communication and mobile communication, no one has attempted to apply it to telephone line expansion. in this paper the author expands the telephone line via dynamic channel borrowing assignment mode, ascertains the expansion scheme, designs the circuit of hardware in telephone line expansion device, draws up software programme, analyses the call lose after using the expansion device theoretically and then experiments to verify it. eight subscribers can share one or two telephone lines with the help of the telephone line expansion device with each phone a sole number. this makes it possible for subscribers to use any free telephone line. thus increasing the number of subscriber and utilization ration of telephone line. in addition. this project makes it possible for expansion subscribers to communicate directly while not to make use of outer line. which further decreased the system call lose
多通道共用是通信通道擴容的一種有效的方法,已在衛星通信、移動通信中得到應用,但尚未應用到電話線路擴容中。本文利用多通道共用原理對電話線路進行擴容,確定了多通道共用方式電話線路擴容的設計研究方案,研究設計了電話線路擴容器的硬體電路,編制了電話線路擴容器的軟體,並對使用電話線路擴容器后的呼損進行了理論分析及試驗研究。本文研究設計的多通道共用方式電話線路擴容器可以使8個用戶共用1 2對電話線路,每部用戶話機都具有獨立的電話號碼,可以利用任一空閑的電話線路,故能夠增加電話用戶,提高電話線路的利用率。The core of the coder is microcontroller - at89c51, the hardware circuits include two parts : display circuit, keys circuit, used for writing detectors ’ id and transmission channels codes
寫碼器以at89c51為核心,硬體電路包括顯示介面、按鍵設計兩個部分,主要用來為探測器寫探頭編號和無線傳輸的通道。分享友人
