摘　　要：工业以太网EPA标准的智能仪表需要通过集成工具才能集成到控制系统中.针对支持EPA的集成工具不多的现状,提出了一种通用型EPA OPC服务器模型,以简化研发难度、提高可复用性和降低成本.进行了EPA功能块、设备行规的标准化工作.在规范化的设备模型上,提出了通用型EPA OPC服务器模型.针对EPA流量计、差压变送器等类型的智能仪表,进行了通用型EPA智能仪表驱动的研发.在OPC开发包的支持下开发了EPA OPC服务器.开发的软件通过了重庆市软件评测中心的测试,并进行了集成到控制系统、应用于工业生产现场的测试.测试结果表明EPA OPC服务器具有良好的一致性、开放性和通用性.Integrating tools are necessary for integrating EPA intelligent instruments into control systems. Due to the shortage of EPA integrating tools, a generic EPA OPC server model was introduced in this study. The model reduced the difficulty of deployment, increased the reuse ability and lowered cost. Standardization work on EPA function block and device profile was carried out. A generic EPA OPC server model was given out based on the standardized device model. Drivers for EPA flow meters and pressure transmitters were deployed. With the support of OPC deployment kit, an EPA OPC server was built. The OPC server passed the software test of Chongqing Software Testing Center. Through integrating into configuration software and practical application in industrial field, the EPA OPC server was tested. The testing result proved that the OPC server had the advantages of consistency, openness and universality.
