Design of an Oil Tank Measurement and Control System Based on LONWORKS Technology

To improve the automatic level of the large tank farm detection, the oil tank measurement and control system based on Lon works field bus were built, which can monitor the oil tank in remote monitoring center and display the measurement parameters by the LCD in the field. The system uses the advanced measurement approach to improve the measurement accuracy and real-time. The system consists of filed instruments on tanks, Data Processing Units, Lon Works network and monitoring computers. The Host-Based Data Processing Units can integrate a variety of instrument output signal or different communication protocols in one system, which ensured good compatibility and reliability. The designed system has been successfully applied to a tank farm. Thus another approach of remotely monitoring the large tank farm is founded. The system structure, the measurement principle, hardware and software design of Data Processing Units are introduced.
