Auto Control System Design Of Seaport Storage And Transportation Operation

This thesis focuses on how to realize the automatic control system design of seaport storage and transportation operation.It reports the overall design ie.network structure of control system,PLC controller with fieldbus module communication network structure,monitoring system structure of radar level meter and controller system structure of electric quantity measurement.It demonstrates how to detect and control PLC and different meters and equipment on the spot.It introduces the communication protocols of profibus DP and designs the distributed control system based on profibus DP combined fieldbus I/O with PLC central processor.In addition,it develops the graphic monitoring of operating system and computer management system and instrument detection.As a result of current research it is concluded that this design can realize the management_control integration system of storage and transportation in oil reservoir with safety and efficiency.
