4、设法获得高品质的自来水并制定科学的水质评价体系成为自来水处理厂发展的重点。但是在实际运行过程中,由于监控系统中的水质参数和运行状态等数据不能被实时的检测和处理,水厂不但需要投入力量手工抄表,更无法及时掌握水质情况并做出反馈。所以研究水厂数据通信与处理方法,开发气浮车间报表自动生成系统,进一步研究水质评价方法,对降低运行成本、提高水厂运营效率有重大意义。本文首先描述了自来水厂自控系统以及网络架构,分析了自来水处理的工艺流程,进而设计了运行数据实时检测与处理系统的总体方案。论文包含如下工作: 1、基于 OPC 技术,采用 Client/Server 模式,借助 Rslinx 通讯软件构建服务器,通
