  4. For the image acquisition of optical scan mode, normally, ccd image sensor is used to capture image, but in our system, due to the system request of micromation and high integration, cmos image sensor is adopted as the image collection device, and then the thesis gives a interface circuit between the chip and dsp and a control solution of image collection ; toward the information storage in our solution, dsp is directly linked to usb host chip and it is the dsp that accomplishes the processing of usb protocol and interface control so as to reduce the cost, minimize product cubage and consequently meet the requirement of system micromation ; at the same time, the thesis probes preliminarily into usb otg ( on - the - go ) technology, which offers an approach between embedded machines including pda, mobile phone, printer, digital camera and so on ; in addition, some attempts on the other application area with tms320vc5402 which was commonly used to voice processing and static image processing are done, for example, to arrange the chip to control lcd module directly

    在圖像的光電掃描輸入上，傳統方案大部分採用ccd型圖像傳感器，而在本方案中，根據系統微型化、高集成的特點，使用了cmos圖像傳感器作為攝像器件，並且設計了該晶元與dsp的一種介面電路以及圖像採集控制方案；在信息存儲上，本方案採用dsp直接與usbhost晶元連接，由dsp處理usb協議和介面信息，從而降低了系統成本、縮小了產品體積，滿足了系統微型化的要求；同時本論文也對usb - otg技術進行了初步探討，利用此項技術，不再需要計算機作為主機，就能實現在pda 、移動電話、印表機、數碼相機等嵌入式應用之間直接互聯通信；另外也對廣泛用於語音處理和靜態圖像處理的tms320vc5402其它方面的應用進行了嘗試，比如直接控制液晶顯示器等。
  5. As cleaning always involves only a small part of the filtration area, i. e. only a small number of filter candles are cleaned at any time, back - flushing is very fast and highly effective. filtration is not interrupted during the back - flushing process. the only moving parts are the back - flushing arm and the flow control device ; their plastic bushings re - adjust automatically and therefore wear and maintenance costs are extremely low

    反沖洗耗水量少：本機反沖時同一時間只清洗一到兩只濾芯，占整個濾芯數量的十幾到二十幾分之一，所以排污耗水量小於設計流量的5 % ，反沖洗可自動定時差壓手動切換，可編程序控制器plc控制。
