在本軟件設(shè)計中，開發(fā)平臺采用WindowsNT。為保證系統(tǒng)的實時性和可靠性，充分利用匯編語言實時功能強，而高級語言運算能力強的優(yōu)點，采用MSVB5.0和8088匯編語言混合編程方式。匯編語言執(zhí)行速度快，且能有效地控制硬件，因此，采用匯編語言子程序來完成數(shù)據(jù)采集、通信等工作。利用高級語言來完成上位機的數(shù)據(jù)處理、顯示、打印等工作。

整個軟件系統(tǒng)由四部分組成，即網(wǎng)絡(luò)初始化程序，數(shù)據(jù)采集程序，數(shù)據(jù)通信程序，數(shù)據(jù)處理與管理程序，各子程序采用模塊化設(shè)計。

3.1 網(wǎng)絡(luò)初始化程序

網(wǎng)絡(luò)初始化程序?qū)W(wǎng)絡(luò)進行初始化，設(shè)置網(wǎng)絡(luò)、網(wǎng)卡(通信適配卡)和采集前端機的工作方式，確定網(wǎng)卡是否允許越限中斷，是否允許事件中斷，是否自動查詢前端，選擇網(wǎng)絡(luò)工作方式：循環(huán)或主從方式。給各主機的工作方式：只聽或聽講。對閃端采集機的工作模式、采樣周期、通道個數(shù)等進行設(shè)定。

3.2 數(shù)據(jù)采集程序

數(shù)據(jù)采集程序用于現(xiàn)場采樣，裝配在采集站中。生產(chǎn)過程的信號有模擬量和數(shù)字量兩類。數(shù)字量包括開關(guān)量和脈沖量二種。開關(guān)量有掃描型和中斷型之分。對不同的實時檢測點設(shè)計成相應(yīng)的數(shù)據(jù)采集軟件，分別完成從相關(guān)設(shè)備采集相關(guān)的數(shù)據(jù)，進行預(yù)處理以組織成供通信軟件傳送的格式。

3.3 數(shù)據(jù)通信參數(shù)

數(shù)據(jù)通信程序由數(shù)據(jù)發(fā)送模塊和接收模塊構(gòu)成。它實際上是單片機之間的(通信適配卡與采集站都是以單片機為核心構(gòu)成的)通信。通信適配卡發(fā)送上位機對采集站的命令;接收采集站的實時數(shù)據(jù)，供上位機調(diào)用。
