摘　　要：在凸度仪系统中,高温扫描仪用于实时测量热轧钢板的断面温度,所测得的温度数据用于对钢板厚度进行实时补偿,反馈给轧机调整板型。为实时获得钢板温度数据,需开发OPC客户端,与高温扫描仪的OPC服务器接口进行数据交互。本文介绍和分析了OPC DA规范,在Visual C++开发环境下,基于活动模板库实现了OPC客户端接口程序,可获取高温扫描仪的各数据项。温度数据传送给温度补偿模块进行厚度校正,获得了较好的校正效果。In an instantaneous profile gauge system,the scanning pyrometer is used to measure temperature of the hot strip section.The acquired temperature data are applied in strip thickness compensation,so that the compensated thickness can be fed back to the rolling mill to adjust the strip profile.In order to acquire real time strip temperature data,an OPC client is needed to interact with OPC server of the scanning pyrometer. The OPC data access specification was introduced and analyzed.In the Visual C＋＋ development environment,an OPC client program was implemented based on the Microsoft active template library（ATL）,so that data items of the scanning pyrometer can be acquired.The acquired temperature data were delivered to temperature compensation module for thickness correction and a good correction result was obtained.
