故障诊断在现场总线设备管理系统中的应用

The Application of Fault Diagnosis in Fieldbus Device Management System

介绍了现代工业生产设备的发展状况,分析了设备的故障诊断和状态监测在工业生产中的重要性,在此基础上发现状态监测和故障诊断与现场设备管理系统没有紧密的结合,使其应有的作用没有得到充分发挥。针对这种情况,研究分析了故障诊断的软件结构和状态监测的硬件结构,搭建了集成故障诊断的现场总线设备管理系统的软件平台,采用模块化的设计完成了设备管理系统的软件架构和在线监测诊断软件架构,进而开发出了集成状态监测和故障诊断的现场总线设备管理系统,目前该系统已经在辽宁某污水厂实际应用,实现了对现场设备的状态监测和故障诊断,为设备开展预测性维修提供了有效的管理平台,为企业的设备管理与维护节约了生产成本。

The paper introduce the development of modem industrial production equipment, and to analyze the importance of the equipment fault diagnosis and condition monitoring in industrial production. The equipment trouble diagnosis and the status inspection are one of the important means of equipment modernization management, but due to the isolation between the condition monitoring, the fault diagnosis and the device management system at present, they could not function very well. To deal with this problem, research and analysis software structure of fault diagnosis and hardware architecture of condition monitoring, build a fieldbus devices management system software platform integrated fault diagnosis and complete software architecture of device management system and on-line monitoring fault diagnosis based on modular design, and then develop the fieldbus device management system integrated condition monitoring and fault diagnosis. The system provides an effective management platform for implementation of predictive maintenance in company successfully The system has practical applied in wastewater treatment plant in Liaoning, and achieve on-site equipment condition monitoring and fault diagnosis, and also production costs for equipment management and maintenance.
