基于FDT与DD技术现场总线设备管理系统设计

The Design of Field Bus Asset Management System Based on FDT and DD Technology

结合现场设备工具(FDT,Field Device Tool)和设备描述技术(DD,Device Description)的特点,设计了基于现场设备工具与设备描述相结合的现场设备管理系统。阐述了利用现场设备工具和设备描述技术,针对不同的现场设备实现现场设备的集成和信息的获取,实现了对设备调试、组态、标定和维护报告等管理功能。并对该系统各项指标进行了测试验证,达到了现场总线设备管理应用要求——集中设备信息存储管理、实时总线设备信息通讯和分布式客户端设备信息访问。

The paper analysed field device tool （FDT） and device description （ DD ）, then designed field bus asset management open system based on FDT and DD. It introduced the applying technology of FDT and DD to realize equipment integrated and information obtained against different equipment. The system realized the functions of debug- ging, configuration, signal calibration, maintenance reports, etc. , besides this management system has been tested and achieved the user＇ s requirement-concentrating the management of asset information, real-time communicating with asset information and distributed client accessing asset information.
