Description
本発明は、接近しつつある船舶同士の横切りや行き会いなどの関係に至る状況の発生時に、船舶同士が互いに安全な航過を行えるようにするための船舶間の航行意思疎通支援装置に関する。 The present invention relates to a navigation communication support device between ships so that ships can perform safe navigation with each other in the event of a situation that leads to a relationship such as crossing or meeting between ships approaching each other.
従来、船舶の相互間で横切り等の見合い関係に至る状況での避航操船は、海上衝突予防法等の規則により定められている現針路保持権利および避航義務にしたがって実施されている。しかし、この権利義務関係は、1対1の状況について規定されており、複数船との遭遇の場合、判断がつきにくい場合がある。また、実際の遭遇時には、相互間の意思疎通を行う手段がないため、目に見える大きな変針操船の実施や、無線通信による連絡で、避航操船が行われる状況を確認している。さらに、避航操船を行う場合、相手船が自船の前方を横切るのか、後方を横切るのかを、相手船の行動から類推して操船を行っている状況で、このような不確実な予想に基づく操船により、実際にはいくつかの衝突事故が誘発されている。 Conventionally, an evacuation ship in a situation where a cross-over relationship, etc. between ships has been achieved is carried out in accordance with the current course holding right and the evacuation duty stipulated by rules such as the Maritime Collision Prevention Law. However, this right-to-duty relationship is defined for a one-to-one situation, and it may be difficult to judge when encountering multiple ships. Moreover, since there is no means for mutual communication at the time of actual encounters, we have confirmed the situation in which evasive maneuvering is carried out through the implementation of large visible marine vessel maneuvering and wireless communication. Furthermore, when evacuating a ship, it is based on such uncertain expectations that the ship is maneuvering by analogy with the actions of the other ship, whether the other ship crosses the front of the ship or the back. Maneuvering has actually triggered several collisions.
そこで、自船から無線通信により相手船へ電子的な位置に関する質問を自動的に送信して、その返信を受けるとともに、相手船から自船への質問も受けるようにして、相互通信により両船間の位置情報を交信するものが開発されているが、現在のレーダーの信号の確実性を強化しているにすぎず、衝突防止のための相互の航行意思疎通を可能にするものではない。
本発明は、船舶の相互間における避航操船に際して、相互の意思疎通を十分に行い、コンピュータ画面上でも航過に伴う危険性の排除を確認できるようにして、衝突防止のための安全性を十分に向上させるようにした、船舶間の航行意思疎通支援装置を提供することを課題とする。 The present invention provides sufficient safety for collision prevention by providing mutual communication and avoiding the danger associated with over-travel on the computer screen when the ship is evacuated. It is an object of the present invention to provide a navigation communication support device between ships, which is improved to the above.
本発明の船舶間の航行意思疎通支援装置は、洋上で遭遇した船舶同士が相互に相手船の特定を行い、かつ、相互に任意の情報を送受信すべく、各船舶に設けられた送受信機と、同送受信機で識別された相手船の位置および進行方向を画面上に表示すべく各船舶に設けられたコンピュータ付き表示器とを備え、同表示器の画面上に表示された相手船との衝突回避のための判断を支援すべく、自船の予定航路および相手船の推定航跡を画面上に表示するための予定航路表示手段と、自船の衝突回避のための操船意思を表明すべく、上記表示器の画面上に表示した自船の予定航路および回避操船の際に航過予定の相手船の船体の部位を特定し、操船意思情報として相手船へ送信するための操船情報送信手段とを備え、上記船舶同士の一方の船舶から上記操船意思情報の送信を受けた他方の船舶が、同操船意思情報の受信内容を上記表示器上に表示し、かつ、画面上で了承または拒否の確認を行うべく各船舶に設けられた航行意思確認手段と、同航行意思確認手段による確認結果を相手船へ返信するための確認結果返信手段と、同確認結果返信手段による返信の内容を上記表示器の画面上に表示する確認結果表示手段とが装備されたことを特徴としている。 The navigation communication support device between vessels according to the present invention is a transmitter / receiver provided in each vessel so that vessels encountered on the ocean mutually identify each other's vessels and send / receive arbitrary information to / from each other. A display with a computer provided on each ship to display on the screen the position and traveling direction of the other ship identified by the transceiver, and with the other ship displayed on the display screen In order to support judgments for collision avoidance, to express the planned route display means for displaying the planned route of the ship and the estimated track of the partner ship on the screen, and to express the intention of maneuvering to avoid the collision of the ship The ship navigation information transmitting means for identifying the planned route of the ship displayed on the screen of the display unit and the part of the hull of the other ship scheduled to be navigated during the avoidance maneuvering and transmitting to the other ship as the ship maneuvering intention information And from one of the above ships The other ship that has received the information on the intention to operate the ship displays the received information on the intention to operate the ship on the display and the navigation provided for each ship to confirm the acceptance or rejection on the screen. Intention confirmation means, confirmation result reply means for returning the confirmation result by the navigation intention confirmation means to the other ship, and confirmation result display means for displaying the contents of the reply by the confirmation result reply means on the screen of the display unit. And is equipped with.
本発明の船舶間の航行意思疎通支援装置では、接近してくる相手船に対し送受信機を用いて相手船の特定が行われるとともに、同送受信機で特定された相手船の位置および進行方向がコンピュータ付き表示器の画面上に表示されるので、自船の進行方向を上記表示器の画面上に表示することにより両船の位置関係が明瞭に確認できるようになる。 In the navigation communication support device between ships according to the present invention, the partner ship is identified using a transceiver for the approaching partner ship, and the position and traveling direction of the partner ship identified by the transceiver are determined. Since it is displayed on the screen of a display with a computer, the positional relationship between the two ships can be clearly confirmed by displaying the traveling direction of the ship on the screen of the display.
そして、自船の予定航路および相手船の推定航跡も、予定航路表示手段によって上記表示器の画面上に表示されるようになる。 The planned route of the ship and the estimated track of the partner ship are also displayed on the screen of the display by the planned route display means.
さらに、操船情報送信手段により、上記表示器の画面上に表示された自船の予定航路と、回避操船の際に航過予定の相手船の船体の部位(船首部,船尾部,右舷,左舷,船首右肩部,船首左肩部,船尾右肩部,船尾左肩部)とについても、操船情報送信手段により操船意思情報として相手船へ送信され、相手船の表示器における画面上に表示されるようになる。 Furthermore, the ship maneuvering information transmission means and the ship's planned route displayed on the screen of the above-mentioned display and the part of the hull of the partner ship to be navigated during the avoidance maneuvering (the bow, stern, starboard, port) , Bow right shoulder, bow left shoulder, stern right shoulder, stern left shoulder) are also sent to the other ship as ship maneuvering intention information by the ship maneuvering information sending means and displayed on the display of the other ship's display It becomes like this.
そして、接近しあう船舶同士の一方から他方へ操船意思情報の送信が行われると、同情報を受けた船舶では、その受信内容を表示器上に表示して、航行意思確認手段により画面上で了承または拒否の確認を行い、同確認手段による確認結果は相手船へ確認結果返信手段により返信され、このようにして上記了承の確認が達成されるまで相互に通信が行われるので、十分な意思疎通により船舶同士の衝突の回避が確実に達成されるようになる。 Then, when the vessel handling intention information is transmitted from one of the approaching vessels to the other, the vessel receiving the information displays the received content on the display, and on the screen by the navigation intention confirmation means. Confirmation of acceptance or rejection is confirmed, and the confirmation result by the confirmation means is returned to the other ship by the confirmation result reply means, and communication is performed until the confirmation of the approval is achieved in this way. Through communication, avoidance of collision between ships can be reliably achieved.
すなわち、本発明の船舶間の航行意思疎通支援装置によれば、自船の計画航路上に、判断の難しい避航状況が発生した場合、事前に相手船に対して航行意図を伝え、これを確認することにより、従来の推測による避航操船よりも安全で確実な避航操船を実現できるようになる。 That is, according to the navigation communication support device between ships according to the present invention, when an evacuation situation that is difficult to judge occurs on the ship's planned route, the navigation intention is notified to the other ship in advance and confirmed. By doing so, a safer and more reliable evacuation ship can be realized than the conventional evacuation ship.
