摘　　要：通过分析目前工业现场存在的设备种类繁多,不同厂商提供的设备在系统集成时存在复杂性及困难性等现状,提出利用FDT/DTM与EDDL相结合的技术实现不同设备的集成。针对FDT技术在设备故障诊断方面的不足,提出了在设备类型管理器(DTM)中融入故障诊断功能,构建了故障诊断DTM模型,实现了对在线设备运行状态的实时监视和诊断,以提高工业生产的安全性。最后给出了将FDT/DTM技术与故障诊断技术相结合的系统。There are a wide variety of equipments in the industrial field, and it is very difficult and complex for system integration when the equipments are provided by different manufacturers. In this paper, we propose a technology to achieve the integration of different de- vices by combining FDT/DTM and EDDL technologies. Then, according to the limitation of FDT in equipment fault diagnosis, a method of embedding fault diagnosis function in the DTM model is proposed and the DTM fault diagnosis model is developed. The method is used to the real - time monitoring and diagnosis of the status of the on - line equipment, and it can improve the security of industrial production. In the end, this paper gives the design of the system which combines FDT/DTM technology and fault diagnosis technology.
