在航電系統維護過程中,為解決定位故障的效率和降低維修成本等問題,提出了基于ICD(Interface Control Document,接口控制文件)的1553B總線的信息監控系統模型。該系統運用數據采集卡對總線中傳輸的信號有無失真、偏差等電氣特性進行檢測,并使用1553B通訊卡通過測控軟件LabWindows/CVI編程與ICD數據庫的動態鏈接,實現總線信息的解析和故障的判斷。與傳統的維護過程相比,這種模型能夠從信號的電氣特性以及信息的解析等全方位的去檢測判斷故障的來源,并且能夠廣泛在其他1553B總線系統內擴展應用。驗證表明該監控系統可以對總線信息進行快速有效地監測分析,能滿足應用需求。 Abstract: In the process of avionics system maintenance, to solve the problems such as improving the efficiency of fast orientation to troubles and reducing maintenance cost, system of 1553B bus information monitor model based on ICD was proposed. The system observed whether the data which transmitted on the bus appear distortion and deviation by using data acquisition card. And using 1553B communication card programming of the measure software LabWindows/CVI and the dynamic linking of ICD Database, message analysis and fault estimation could be realized. Compared with traditional maintenance, this model can all-dimensionally detect and analyze the source of faults from both electrical characteristics of the signal and message analysis, and it can be widely applied in the other 1553B system. Experiment shown that this monitor system can effectively detect and analyze the bus message and can meet the application requirements.

.MS Access Database方式 設計過程中的全部文件都存儲在單一的數據庫中,同原來的Protel99文件方式。即所有的原理圖、PCB文件、網絡表、材料清單等等都存在一個.ddb文件中,在資源管理器中只能看到唯一的.ddb文件。 2. Windows File System方式 在對話框底部指定的硬盤位置建立一個設計數據庫的文件夾,所有文件被自動保存的文件夾中。可以直接在資源管理器中對數據庫中的設計文件如原理圖、PCB等進行復制、粘貼等操作。 注:這種設計數據庫的存儲類型,方便在硬盤對數據庫內部的文件進行操作,但不支持Design Team特性。 二、 方便的文件查找功能

這個軟件需要你的本機操作的。其他機器是算不出來的! 就是說 一臺電腦只有一個注冊碼對應! 這里有個辦法: MULTISIM2001安裝方法: 一:運行SETUP.EXE安裝。在安裝時,要重新啟動計算機一次。 二:啟動后在“開始>程序”中找到STARTUP項,運行后,繼續進行安裝,安裝過程中,第一次要求輸入“CODE"碼時, 輸入“PP-0411-48015-7464-32084"輸入后,會提示"VALID SERIAL NUMBER FOR MULTISIM 2001 POWER-PRO." 按確定,又會出現一個“feature code”框,輸入“FC-6424-04180-0044-13881”后, 在彈出的對話框中選擇“取消”,一路確定即可完成安裝。 三:1.運行VERILOG目錄內的SETUP安裝 2.運行FPGA目錄內的SETUP安裝 3.將CRACK目錄內的LICMGR.DLL拷貝到WINDOWS系統的SYSTEM 目錄內 4.并將VERILOG安裝目錄內的同名文件刪除 5.將SILOS.LIC文件拷到VERILOG安裝目錄內覆蓋原文件,并作如下編輯: 6.將“COMPUTER_NAME”替換為你的機器名 7.將“D:\MULTISIM\VERILOG\PATH_TO_SIMUCAD.EXE”替換為你的 實際安裝路徑。如此你便可以使用VERILOG了。 四:安裝之后,運行MULTISIM2001,會要求輸入“RELEASE CODE",不用著急, 記下“SERIAL NUMBER"和“SIGNATURE NUMBER", 使用CRACK目錄內的注冊器“MULTISIM KEYGEN.EXE" 將剛才記下的兩個號碼分別填入后, 即可得到"RELEASE CODE", 以后就可以正常使用了。 五:接下來運行 Database update目錄中的幾個文件, 進行數據庫合并即可。祝你成功!! 六:啟動MULTISIM2001時候的注冊碼 1: PP-0411-48015-7464-32084 2: 37506-86380 3:的三個空格 1975 2711 4842 里面包含了:Multisim2001漢化破解版、Multisim.V10.0.1.漢化破解版圖解 解壓密碼:www.pp51.com

ADO.NET in a Nutshell is the most complete and concise source of ADO.NET information available. Besides being a valuable reference, this book covers a variety of issues that programmers face when developing web applications or web services that rely on Database access. Most examples use Microsoft s C# language. The book s CD includes an add-in to integrate the reference with Visual Studio .NET help files.

Setting up an ADOCE project using Visual C++ 6.0 is rather simple. Assuming that you have downloaded and installed the ADOCE SDK from Microsoft, you are ready to use it in your Windows CE Database applications. The sample that I have provided is a *very* simple one illustrating how to instantiate the proper COM objects, and the basics of how to interface with them (in a very simple example)
