本文以PIC24FJ64GA002 16位單片機為處理器控制10BASE-T SPI以太網控制器ENC28J60,實現了單片機的上網。應用Microchip TCPIP Stack協議,實現了HTTP,FTP協議和基于CGI動態網頁的設計。操作員可以在遠程計算機上以Web頁面的方式實現系統的監控,也可以通過FTP更新系統參數和數據。最后將本系統應用在了生物發酵遠程監控系統中,得到了良好的效果。

ZOPC_Server是一個OPC服務器軟件,本軟件通過插件方式操作底層硬件。其中三個標準插件(CAN,DeviceNet,iCAN)支持操作全部的ZLGCAN系列接口卡 和ZLGDeviceNet系列板卡以及iCan協議系列卡,只要在一臺PC機上插上ZLGCAN系列接口卡或ZLGDeviceNet系列板卡中的任何一種或幾種,再運行本服務器軟件,在服務器軟件中進行一些相關配置以后,就可以使用任何一種支持OPC協議的客戶端軟件(比如組態軟件:組態王、MCGS和INTOUCH等等)來連接到此服務器,通過此服務器來跟CAN網絡、iCAN網絡或DeviceNet網絡進行數據的傳輸。 ZOPC服務器現階段帶有五個擴展插件,分別為CANopen,DAQ,GPRS,Modbus,Modbus_RTU_ASCII。這些擴展插件可以按需要單獨安裝。CANopen插件可操作ZLG生產的CANopen主站卡。DAQ插件操作ZLG的DAQ系列數據采集卡,將數據采集卡采集的數據上傳到ZOPC服務器中供客戶端使用。GPRS插件可以將GPRS模塊的數據上傳到ZOPC服務器中。Modbus插件是通過以太網操作從站。Modbus_RTU-ASCII插件是通過串口操作從站。隨后還會添加新的插件支持對新開發的產品的操作。

The exacting technological demands created byincreasing bandwidth requirements have given riseto significant advances in FPGA technology thatenable engineers to successfully incorporate highspeedI/O interfaces in their designs. One aspect ofdesign that plays an increasingly important role isthat of the FPGA package. As the interfaces get fasterand wider, choosing the Right package has becomeone of the key considerations for the systemdesigner.
