碩士 / 國立成功大學 / 系統及船舶機電工程學系碩博士班 / 95 / The development of technology has significantly promoted the navigation industry. Therefore, dynamic positioning systems become necessary for high-performance ships. So far, in the world, there are more than 1,000 ships that have installed dynamic positioning systems. However, entire ships are considered as a huge system, and the presence of dynamic positioning systems will increase the system complexity, which will consequently increase the difficulty of installation and the cost. Hence, this research applies CAN Bus to dynamic positioning system for a preliminary realization of such a system. CAN Bus is a distributed control network that can simplify the wire connections. The advantages of CAN Bus include long transmission distance and decent ability of noise rejection, and hence it is suitable for use on ships. This research employs GPS and digital compass as the positioning sensors. Three digital signal processors (DSP) are used as the controllers. The thruster system is composed of three brushless DC motors with three propellers. Through CAN Bus, positioning signals and control signals are transmitted around every DSP, and thus the reliability is increased. The experiment is performed by applying the developed system on a ship model for realization and feasibility verification.
