基于LonWorks技术的油罐测控系统设计

Design of Oil Tank Measurement and Control System Based on Lonworks

为提高大型油罐区检测自动化水平,采用LonWorks现场总线技术设计的油罐区自动测控系统,能够实现就地显示和远程监控油罐实时状态,Host-Based结构的智能测控节点兼容多种通用的油罐测量仪表信号类型,系统兼容性强,易于扩展。所设计的系统已成功应用于某油罐区监控,介绍了该测控系统的结构和工作原理、智能测控节点硬件和软件设计与实现。

To improve the detection of the large oil tank,the oil tank measurement and control system based on Lonworks can manage remotely the oil tank and display the measurement parameters by the LCD screen in the field.The Host-Based Lonworks node integrates a variety of instrument output signal,which ensured good compatibility and reliability.The designed system has been successfully applied to a oil tank.The system structure,the measurement principle,hardware and software design of the network node are introduced.
