摘　　要：为适应不断完善的水质COD处理工艺,一个完备的监控系统成为必不可少的关键要素。在介绍COD在线监控系统硬件组成和体系结构的基础上,详细描述了COD远程在线监控系统的实现。利用LabVIEW虚拟仪器开发平台设计监控系统界面,采用Hostlink协议、DataSocket和Web与欧姆龙CP1H系列PLC连接,建立OPC服务器,实现数据采集与访问控制以及异地远程在线监控和维护。实验结果表明,该系统界面友好,运行稳定可靠,能较好地实现水质COD检测处理过程的集中和远程监控。In order to adapt to the constantly improved COD（ chemical oxygen demand） treatment process for water quality,a complete monitoring system becomes an indispensable key element. On the basis of introduction of the hardware composition and the system architecture of online monitoring system,the implementation of the remote online monitoring system of COD is described in detail. By adopting LabVIEW virtual instrument developing platform,the interface of monitoring system is designed. Hostlink protocol,Data Socket and Web are connected with PLC of OMRON CP1 H series to establish OPC server for realizing data acquisition,access control,and remote online monitoring and maintenance. The experimental results show that the system offers good user-friendly interface,stable operation,and well implements centralized and remote monitoring in the detection and treatment process of COD.
