摘    要：针对唐山中厚板材有限公司炼钢厂现场总线设备数据采集实现复杂的问题,提出了如何运用计算机组件技术,对复杂的OPC客户端访问协议进行重新构建,将其所实现的功能封装于标准化组件里定制为软件包,以简单便捷的方法实现炼钢厂不同现场总线设备数据的实时访问,为炼钢厂数据采集系统的开发提供了一种高效的技术手段。通过在现场数据采集系统中的实际应用,表明该技术使用简单,适用于对遵循OPC协议的硬件设备的数据采集,可以大大缩短用户数据采集系统的开发周期,对提高自动化行业数据访问接口的标准化和设备监控软件的开发有重要指导意义。

Abstract: In steelmaking plant of Tangshan Heavy and Medium Plate Co.,Ltd.,realization of data acquisition for fieldbus equipment was complicated.Computer component technology was used to reconstruct complex OPC client access protocol.Achieved functions were packed in standardization components to form software package,therefore,realtime data access of different fieldbus equipment in steelmaking plant can be achieved in an easy and convenient way,and a highly effective technical means is provided for development of data acquisition system in steelmaking plant.Practical application of field data acquisition system shows that the technique is simple to use,suitable for data collection of hardware equipment which follow OPC protocol,development cycle of user’s data acquisition system is reduced,and it has an important guiding significance in improving the standardization of industry automation data access interface and development equipment monitoring software.
