中文摘要: 现代工业生产过程的数据采集要求高采样率和传输的高实时性,而现有OPC数据采集客户端不能满足要求.为了解决这个问题,通过分析OPC标准、服务器数据访问接口和组建对象模型,并结合当前工业控制中数据采集的特点,设计实现了基于订阅式数据采集方式的OPC客户端.该方案在解决当前工业数据采集中遇到的问题具有较高的应用价值.并在实际的生产环境中验证了其与标准OPC服务器在数据传输的稳定性和实时性,为生产过程控制提供了可靠的数据基础.
Abstract:Data collection in modern industrial production processes requires high sampling rates and high real-time transmission, while existing OPC clients of data acquisition cannot meet the requirements. In order to solve this problem, by analyzing the OPC standard, accessing the server data interface and component object model, combined with the characteristics of data acquisition in current industrial control, the OPC client based on subscription data collection is designed and implemented. This solution has high application value in solving the problems encountered in current industrial data collection. And in the actual production environment, it verifies the stability and real-time performance of the data transmission with the standard OPC server, which provides a reliable data foundation for production process control.
