| In the subject "Multi-Mode Engine Room Process Control Simulation and System Performance Evaluation"(NO.03IK14) , which is financed by the Science and Technology Development Fund of Department of Science and Technology of Shanghai, be dead against the information acnode in the traditional shipping process control system , a FCS(Fieldbus Control System) based on FF(Foundation Fieldbus)is put forward , studied and constructed.The work of this dissertation is accidence explore of FF technology to be used on ships , I designed the system , select the type , create the control strategy and configurated the system , give out a new method based on FF for Engine Room process control system.Main tasks of the dissertation are as follows:· according to the characteristic of engine room process control system , compared the recent main Fieldbus technology, select the field device for the process control system , and connect the devices.· Stydie the fuel oil viscosity control system and cooling water control system include in the engine room process control system , created process control strategy.· Use the OPC interface technology, connect the computer and the field device.· Use the configurator program to configurate the system.This dissertation use the OPC technology connect the computer and field device, use mathematic model to simulate the to be controlled object, solved the problem that there is no object to be controlled in laboratory.The design flow of the FCS is used as a clue to organize materials and construct the dissertation.The structure is planed as follows:Chapter1, prodrome , introduce project background,current status of this subject at home and abroad,tasks , innovational points and meaning.Chapter2, introduce two representative control systems of engine process control systems , viz. viscosity control system and cooling water temperature... |
