摘　　要：针对造纸过程中的横向定量控制系统,具体分析了OPC客户端与现代造纸机横向定量控制系统之间的数据通信。基于LabVIEW设计了一种动态创建OPC客户端的方法,通过调用配置文件,在库中实现了OPC客户端的动态创建,该OPC客户端程序具有动态绑定共享变量和动态部署库的功能,而且具有很好的自适应性和可移植性。采用订阅访问的方式访问了现场的OPC测量服务器,实现了读取横向定量控制过程中的测量数据,大大提高了数据访问的效率。通过实际应用效果证明采用本方案开发的横向定量控制系统的有效性和可行性。Data communication between OPC client and cross directional basis weight control system of modern paper machine were analyzed in the process of paper-making.A method of creating OPC client dynamically was designed based on LabVIEW and the OPC client was created dynamically in the library by reading the configuration profiles,which had the function of binding the variables and deploying the libraries dynamically and also had good adaptability and portability.The way of subscription to communicate with OPC server was used to achieve the measurement data of cross directional basis weight in the control process,which greatly improved the efficiency of data access.The application results indicated that the cross directional basis weight control system based on the scheme was feasible and effective.
