The Microcontroller-Based Main Engine Fuel Oil Viscosity Control System

With the highly speedy development of computer technology, measurement apparatus, and control technology, more and more advanced technology, equipments and methods for measurement and control are applied in modern automation control realm. And because of the monolithic microprocessor performance-to-price ratio superiority, so it was widely applied in the ships automatic control domain. How to adapt the new science and technology development trend, manage and use ships better, it set a higher request to the modern turbine administrative personnel.The topic is precisely adapted to this trend, and in order to enhance the quality of marine management and provide better teaching and research platform to develop a set "fuel oil viscosity control of microcomputer simulation experiments system "to facilitate the operation of the theory and practice of teaching combined to enable students to better understand the real ship systems and equipment operating principle, maintenance and failure analysis to improve the management capacity of modern vessels.In this paper, various links of the viscosity measurement and control system to conduct functional needs analysis, clearly the present control system to meet the technical requirements, so as to subsequent system design and lay a solid foundation; and then under the system to achieve the functionality of the hardware components choices and steam heat exchanger, implementing agencies such as the establishment of a mathematical model; Finally, the-loop fuel control system of the host system, simulation experiments, and gave details of the system can complete the job of analyzing the deficiencies of the system the department and the improvement measures.With the International Maritime Organization for the crew training requirements for the strengthening of the advanced control equipment, the successful introduction of the teaching process is to solve the theory of teaching and practice of divergence, also contributed to the development of automatic control technology. The ships main engine fuel oil viscosity control analogous system efficiency, the extendibility have also explored a feasible road for the engine room other process control system establishment. has the broad development space.
