摘　　要：水量调度系统是南水北调中线工程自动化调度系统的核心组成部分,由闸站监控系统采集的水位、流量、闸门开度等监测数据反映了输水干渠水量调度控制的实时状态,是水量调度系统中控制指令生成必不可少的输入参数。因此,需要建立水量调度系统与闸站监控系统之间的数据通信。根据OPC基本原理和数据访问规范,提出了基于OPC技术的系统集成方案,即在水量调度系统中开发OPC客户端应用程序,用于实时获取闸站监控系统采集的监测数据,并将指令发送到闸站监控系统。实践表明,基于OPC技术的集成方案能够很好地实现两个应用系统之间的数据传递,降低了系统集成的成本,增强了系统的稳定性和灵活性。Water regulation system is one of the core compositions of automatic dispatching system of the Middle Route of the South-to-North Water Diversion Project（MSNWDP）, The survey data such as the canal water level, flow rate, and sluice gate o- pening a collected by monitoring devices reflect the real-time state of water transfer control in the canal, and they are the neces- sary input data for the water regulation system, Consequently, an appropriate data transfer approach is needed between the wa- ter regulation system and sluice gate monitoring system, Based on the basic principle and data access specification of OPC tech- nique, this paper proposed an （）PC-based system integration scheme to retrieve the real-time survey data from sluice gate moni- toring system and to send control orders back to sluice gate monitoring system,The implementation of water regulation system in the Jingshi Section of MSNWDP suggested that the proposed OPC-based integration scheme can better realize the data trans- fer between the two systems with the reduction of the integration cost and improvement of the system stability and flexibility.
