VB提供了基于Windows Sockets網(wǎng)絡(luò)編程接口的Winsock控件，使得開(kāi)發(fā)TCP/IP應(yīng)用變得簡(jiǎn)單輕松。TCP/IP協(xié)議具有TCP和UDP兩種通信方式。TCP是一種面向連接的服務(wù)，它在兩個(gè)主機(jī)之間建立連接，提供雙向、有序且無(wú)重復(fù)的數(shù)據(jù)流服務(wù)。本系統(tǒng)則從可靠性的角度采用TCP方式進(jìn)行通信。在VB通信窗體中添加三個(gè)Winsock控件，通過(guò)對(duì)其屬性的設(shè)置以及觸發(fā)事件過(guò)程的相應(yīng)處理，輕松實(shí)現(xiàn)了本機(jī)與HT－7總控和炮號(hào)服務(wù)器之間點(diǎn)對(duì)點(diǎn)的通信。
（2）組態(tài)王通過(guò)DDE訪問(wèn)VB
組態(tài)王作為DDE的客戶(hù)程序向VB請(qǐng)求數(shù)據(jù)，獲取VB的通信結(jié)果。VB作為服務(wù)程序，其DDE連接是通過(guò)設(shè)置窗體的LinkTopic、LinkItem、LinkMode來(lái)實(shí)現(xiàn)的，其中LinkMode屬性設(shè)置為1（source）；組態(tài)王則需定義DDE設(shè)備及變量，在變量定義中其連接設(shè)備為已定義的DDE設(shè)備，項(xiàng)目名為VB中用來(lái)接收通信數(shù)據(jù)的控件。
（3）VB程序嵌入組態(tài)王
VB和組態(tài)王分別建立了兩個(gè)不同的應(yīng)用程序，通過(guò)在組態(tài)王應(yīng)用程序命令語(yǔ)言的啟動(dòng)下調(diào)用StartApp()函數(shù)和ReBuildUnConnectDDE()函數(shù)，確保組態(tài)王啟動(dòng)時(shí)自動(dòng)打開(kāi)VB開(kāi)發(fā)的應(yīng)用程序，并重建未成功的DDE連接。另外，還可以考慮對(duì)VB窗體的隱含。實(shí)現(xiàn)VB與組態(tài)的完美結(jié)合。
3.3數(shù)據(jù)存儲(chǔ)與管理方案
3.3.1問(wèn)題的提出
在組態(tài)王6.5版本中數(shù)據(jù)采集頻率可設(shè)定為毫秒級(jí)，數(shù)據(jù)保存可按“定時(shí)記錄” 和“數(shù)據(jù)變化記錄” 兩種方式。其中“定時(shí)記錄”方式最快的數(shù)據(jù)保存頻率是1個(gè)/分；而“數(shù)據(jù)變化記錄”方式雖可實(shí)現(xiàn)數(shù)據(jù)毫秒級(jí)高速存儲(chǔ)和數(shù)據(jù)壓縮，但是，如果直接利用組態(tài)王所提供的歷史報(bào)表，通過(guò)ReportsetHistData()函數(shù)進(jìn)行數(shù)據(jù)查詢(xún)時(shí)，其查詢(xún)數(shù)據(jù)的最小時(shí)間間隔只能為1秒鐘。當(dāng)實(shí)際要求以固定毫秒級(jí)時(shí)間間隔實(shí)現(xiàn)數(shù)據(jù)的按次存儲(chǔ)與按次查詢(xún)時(shí)，簡(jiǎn)單、直接地使用組態(tài)王是無(wú)法實(shí)現(xiàn)的。
