Description
本発明は、船舶により構成された移動体について、規則正しい運行（運航）と安全性とを確保できるようにした移動体運行管理システムに関する。 The present invention relates to a mobile operation management system capable of ensuring regular operation (operation) and safety for a mobile object constituted by a ship.
従来、電車の運行管理システムとして、電車に搭載されたＧＰＳ受信機で人工衛星の電波を受信することにより電車の位置情報を取得して、運行管理施設の端末機上の地図に線路上の電車位置を示したり、その位置情報に基づき、他の線路状況も考慮して生成された管理情報（運行詳細情報）を電車側へ折り返し送信したりすることが提案されているが、具体的な運転行動については運転者の判断に任されているのが実情である。
従来の移動体運行管理システムは、次のような問題点を有している。
（１）運転時の状態量および操作量等の検出・記録データと不安全行動を規定するデータベースとをリンクした解析が行われていないため、運行管理施設において管理対象移動体で不安全な運転が行われていることが認識できない。
（２）移動体の健全性を最終的に判断するには、運行管理者による詳細な状況把握を行う必要があるが、全ての管理移動体に対して常時状況把握を行うのは現実的でなく、また、注意対象移動体が特定されても、詳細な状況把握を行う情報・手段が無いため、運行管理側が全ての管理対象移動体に対して詳細な状況把握を行うことができない。
（３）運行データの蓄積手段と解析手段とが確立していないため、運行システムの定量的なボトルネックの検索手段が無い。
そこで、本発明は、上述の問題点の解決を図ろうとするものである。
The conventional mobile operation management system has the following problems.
(1) Since there is no analysis that links detection / recording data such as state quantities and manipulated variables during driving with a database that defines unsafe behavior, unsafe driving in a managed mobile unit at an operation management facility Cannot be recognized.
(2) In order to finally determine the soundness of the moving body, it is necessary to grasp the detailed situation by the operation manager, but it is realistic to always grasp the situation for all managed moving bodies. In addition, even if the attention object mobile body is specified, there is no information / means for grasping the detailed situation, so the operation management side cannot grasp the detailed situation situation for all the management object mobile objects.
(3) Since operation data storage means and analysis means have not been established, there is no quantitative bottleneck search means for the operation system.
Therefore, the present invention is intended to solve the above-described problems.
