심해용 ROV의 전기 및 통신 시스템 설계와 구현

Abstract

This paper proposes a design methodology of electrical and communication system for a deep-sea remotely operated vehicle (ROV). Since an electrical and communication for a deep-sea ROV are tightly coupled with other sub-systems, all these sub-systems should be considered at the first design stage, and then their changes have to be fed into the all sub-systems to keep and to adjust a balance of the whole system. Additionally, a deep-sea ROV has a very long cable. It causes difficulties in designing the system, for examples, power loss due to delivery, wired communication without repeater. In this paper, three categories of electrical and communication system, power system, electrical system, fiber optic communication system are explained. A design method of each system is described and its implementation examples are shown from on-going project, \\'the development of an advanced deep-sea unmanned underwater vehicle (UUV)\\' sponsored by the Ministry of Maritime Affairs and Fisheries (MOMAF) since 2001. Based on the development schedule, the vehicles named Hemire and Henubi will launch for exploration on April 2007 after testing and enhancing the performance of the vehicle and operational skill in the East-sea and the Pacific ocean.
