Research And Design Of Ship Min. Fule Consumption Control System

As the world oil market prices rising, people's energy-saving ideas to enhance, birth of many new energy-saving technology.To the marine equipment, Energy-saving is particularly important for marine main, the host ship fuel consumption accounts for a significant portion of operating costs,so, in recent years, the world's major shipping companies a large number of human and financial resources into research and development of low fuel consumption of the host. However, the structure of diesel engines, principles and other aspects it has almost reached its limit.Therefore, saving the ship from the current conditions of the existing equipment digging potential. Reduce fuel consumption,With minimum energy consumption to maximize transportation efficiency. Sailing ship, the required energy form of kinetic energy, electricity and heat, Supply of these energy devices is propulsion, power generation equipment and gas installations, These three devices are directly consumed fuel. Ship diesel engines, for example, direct consumption of diesel fuel is the host of equipment, power generation diesel engines and auxiliary boilers, Among them, the ship hosts of the total energy consumed by the energy of 70～90%.Paper introduces a marine diesel engine min.fule consumption control system. Use this system without affecting the safe navigation of ships and shipping cycle context,through the real-time detection, control the speed of the host running on the minimum fuel consumption, which greatly reduces the host ships with fuel consumption.The major achievement of this reseach could be summarized as follows:1. Analysis of the current economic speed of classification and the calculation. Unit distance of a ship control system for minimum fuel consumption and speed optimization strategy, including the initial optimization strategy, optimizing strategy curve correction strategy and optimization.2. On this basis, the proposed minimum fuel consumption speed ship diesel engine control system and program design and completed the master chip selection.3. To TMS470Rla256 chip as the system main control chip, and carried out in TMS470Rla256 chip embedded operating system uC/OS-Ⅱmigration4. Design of system software, including uC/OS-Ⅱtask partitioning and various programming tasks.
