本文介绍了远程数据实时采集系统的一般通信模型,给出了基于计算机网络的水费数据采集系统的实现步骤。每个站点通过RS232 协议连接多个管道,管道负责记录检测点的水流量。站点和总控机连接到Internet 上, 以TCP 方式进行数据传输。总控机将采集到的水流量数据存放到Oracle9i 数据库服务器中,用户通过浏览器查询到水流量数据。关键字 数据采集、网络通信、Oracle9i、TCPTHE 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.Key words Data Gather、Network Communication、Oracle9i、TCP
