Abstract

電力線通信技術の産業用途の1つとして,船内LANがある.筆者らは昨年,大型貨物船において電力線の通信路特性を測定した.大型貨物船の電力線はすべてあじろがい装されているという特徴がある.本稿では,弓削商船高等学校所有の練習船である弓削丸で同様に測定した結果を示し,大型貨物船の伝達関数との比較を行なっている.弓削丸の全長は大型貨物船の1/5と小さく,無がい装ケーブルも使用されている点が大型貨物船と異なるが,配線トポロジーは同じである.また船外への不要輻射量は信号注入コンセントによって大きくばらつくことを述べている.

Power-Line Communication (PLC) based Local Area Networks (LAN) in ships are one of the promising applications of the PLC technology. The authors measured the characteristics of power-line in cargo ships last year. A feature of power distribution systems in the cargo ships is that all power-line cables in the ships are armored. In this paper, the transfer function of the training ship YUGEMARU is shown and compared with that of the cargo ships. The length of YUGEMARU is shorter than that of the cargo ships, and the unarmored power-line cable is partly used. But topology of the distribution system is the same. Furthermore, it is also shown that the degree of unintentional radiation depends on the outlet into which signals are injected.
