本文介紹了遠程數(shù)據(jù)實時采集系統(tǒng)的一般通信模型，給出了基于計算機網(wǎng)絡的水費數(shù)據(jù)采集系統(tǒng)的實現(xiàn)步驟。每個站點通過RS232 協(xié)議連接多個管道，管道負責記錄檢測點的水流量。站點和總控機連接到Internet 上， 以TCP 方式進行數(shù)據(jù)傳輸。總控機將采集到的水流量數(shù)據(jù)存放到Oracle9i 數(shù)據(jù)庫服務器中，用戶通過瀏覽器查詢到水流量數(shù)據(jù)。

THE REALIZATION OF REMOTE WATER RATE GATHERING SYSTEM SUN Cai_Yun ZHAO Yuan_dong GAO Chao (Department of Information and Control of Nanjing University of Information and Technology Nanjing, china 210044) Abstract: This paper introduces the design and the realization of the remote water rate gathering system. Every station connects to several pipes through the protocol of RS232.Not only station but also Control PC works as a part of network.
