Description
本発明は、航行船舶の個別認識システムに関し、特に、光通信によって船舶を個別認識し、海域内にある有意船と不審船とを差別化する航行船舶の個別認識システムに関するものである。 The present invention relates to an individual recognition system for sailing ships, and more particularly to an individual recognition system for sailing ships that individually recognizes ships by optical communication and differentiates significant ships and suspicious ships in the sea area.
我が国の沿岸にある原子力発電所等の重要施設に対する不審船による不利益工作が懸念されている。
原子力発電所の前面に広がる海域は、主に漁船が操業しており、これに紛れた不審船を差別化するシステムが求められている。
There are concerns about the disadvantageous work of suspicious vessels on important facilities such as nuclear power plants on the coast of Japan.
The fishing area in front of the nuclear power plant is mainly operated by fishing boats, and there is a need for a system that differentiates suspicious vessels.
また、我が国の沿岸線は長く、海上保安庁が行う巡視船による監視等では限界があり、不審船だけではなく密入国船を見逃している現状から、是正が求められている。 In addition, Japan's coastline is long, and there are limits to the monitoring by patrol boats conducted by the Japan Coast Guard, and correction is required from the current situation that missed not only suspicious vessels but also smuggled vessels.
海上監視にブイを利用するにしても最低半径１０マイル程度の範囲をカバーする必要があり、また、不審船や不法入国船は夜間に行動する傾向があるため、赤外線カメラによる船影からの不審船差別化には限界があり、夜間や濃霧の中でも差別化が可能なシステムが求められている。 Even if buoys are used for maritime surveillance, it is necessary to cover a range of at least a 10-mile radius, and suspicious ships and illegally arriving ships tend to act at night. There is a limit to differentiation, and there is a need for a system that can differentiate at night and in dense fog.
一方、総重量３００トン以上の船にあっては、無線電波を使用したＡＩＳ（Ａｕｔｏ Ｉｄｅｎｔｉｔｙ Ｓｙｓｔｅｍ）装置の装備が義務づけられているため、陸上側から各船の固有情報が得られるが、それ以外の船をＡＩＳで認識することはできない。
また、ＡＩＳは国際的な管理の下にＶＨＦ帯の電波を用いて運用するため、電波使用の制限や制約がある。
On the other hand, since ships with a total weight of 300 tons or more are required to equip AIS (Auto Identity System) equipment using radio waves, specific information on each ship can be obtained from the land side. Cannot be recognized by AIS.
Further, since AIS is operated using radio waves in the VHF band under international management, there are restrictions and restrictions on the use of radio waves.
また、光通信の原点ともいえる手旗信号による認識システムは高度な熟練が必要であり、夜間や濃霧等、天候上の制約もある。 In addition, a recognition system using a hand flag signal, which can be said to be the origin of optical communication, requires a high degree of skill, and has restrictions on the weather such as nighttime and dense fog.
本発明は、上記従来の航行船舶の個別認識システムが有する問題点に鑑み、光通信によって船舶を個別認識し、海域内にある有意船と不審船とを差別化する航行船舶の個別認識システムを提供することを目的とする。 In view of the problems of the above-described conventional identification system for a navigation ship, the present invention provides an individual recognition system for a navigation ship that individually recognizes a ship by optical communication and differentiates a significant ship and a suspicious ship in the sea area. The purpose is to provide.
上記目的を達成するため、本発明の航行船舶の個別認識システムは、特定の海域を航行する個々の船舶に、各船舶固有の識別符号に基づいて短時間内に発光と消灯を繰り返す、無指向性で、かつ、常時稼働の光源を備えた光源装置を取り付け、該光源装置の点滅信号を海上又は陸上に設けた撮像装置で検出し、該撮像装置とコンピュータとを連動させて電気信号に置き換えて航行する船舶の個別認識を行うことを特徴とする。 To achieve the above object, the individual recognition system going vessels of the present invention, the individual ships navigating the particular waters, repeated off and emission in a short time on the basis of each vessel unique identification code, omnidirectional A light source device equipped with a light source that is always active and mounted, detects a blinking signal of the light source device with an imaging device provided on the sea or land, and replaces the imaging device with an electric signal in conjunction with a computer It is characterized by the individual recognition of ships that navigate.
この場合において、光源装置が、識別符号としてインターネット上での個別アドレスを発光させるようにすることができる。 In this case, the light source device can be Rukoto so as to emit individual address on the Internet as an identification code.
本発明の航行船舶の個別認識システムによれば、特定の海域を航行する個々の船舶に、各船舶固有の識別符号に基づいて短時間内に発光と消灯を繰り返す光源装置を取り付け、該光源装置の点滅信号を海上又は陸上に設けた撮像装置で検出し、航行する船舶の個別認識を行うことから、例えば、原子力発電所の前面海域で操業希望のある漁船には、全船に当該光源装置を附帯させることにより、管理側のモニター等に昼夜の区別なく識別符号の付いた有意船であることを示すことができるため、不審船がこの海域に入ってきた場合に、即座に信頼性の高い行動を起こすことが可能になる。
また、電波のチャンネルに相当する識別できる船の数は、海域を映し出す画像の画素数に匹敵することから、事実上制約なく運用することができる。
そして、主要な港の入り口にこの航行船舶の個別認識システム導入することにより、小型船を含めた出入港記録を自動化することができる。
According to the navigation ship individual recognition system of the present invention, a light source device that repeats light emission and extinction within a short time is attached to each ship navigating a specific sea area based on an identification code unique to each ship, and the light source device For example, fishing boats that wish to operate in the front sea area of a nuclear power plant should be equipped with the light source device for all ships. As a result, it is possible to indicate that the ship is a significant ship with an identification code regardless of whether it is day or night. It becomes possible to take high actions.
In addition, the number of ships that can be identified corresponding to radio wave channels is comparable to the number of pixels in an image showing the sea area, and therefore can be operated with virtually no restrictions.
And by introducing this individual recognition system for navigating ships at the entrances of major ports, it is possible to automate the entry and exit records including small ships.
また、撮像装置がコンピュータに連動し、光学面の画素に当たる光の強弱を電気信号に置き換えることにより、個別認識した船舶の情報処理を容易にすることができる。 In addition, the information processing of the individually recognized ship can be facilitated by replacing the intensity of light hitting the pixels on the optical surface with an electric signal in conjunction with the computer.
以下、本発明の航行船舶の個別認識システムの実施の形態を、図面に基づいて説明する。 DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a navigation ship individual recognition system according to the present invention will be described below with reference to the drawings.
図１に、本発明の航行船舶の個別認識システムの一実施例を示す。
この航行船舶の個別認識システムは、特定の海域Ａを航行する個々の船舶に、各船舶固有の識別符号に基づいて短時間内に発光と消灯を繰り返す光源装置１を取り付け、該光源装置１の点滅信号を海上又は陸上に設けた撮像装置２で検出し、航行する船舶の個別認識を行うようにしている。

This individual recognition system for navigating ships attaches to each ship navigating a specific sea area A a light source device 1 that repeats light emission and extinction within a short time based on an identification code unique to each ship. The blinking signal is detected by the imaging device 2 provided on the sea or on the land, and the individual recognition of the ship to be navigated is performed.
図１において、海上交通センター３、海上保安部４、灯標５、安全水域標識６及び複数の灯標１１は撮像装置２を備えており、光源装置１からの光信号７を検出する。
また、大型船９及び旅客船１０はＡＩＳを搭載しており、ＡＩＳの電波信号８を受発信する。
小型漁船１２、小型レジャー船１３及びその他の複数の小型船１４は、光源装置１を備えている。光源装置１は、ＡＩＳ等を搭載することなく、そのままでは識別力がない全ての船舶に装備される。
光源装置１の点滅信号は海域１６側から海域１６又は陸１５側で検出され、点滅信号を置き換えた電気信号１７、１８は陸上施設間を流れる。
In FIG. 1, the maritime traffic center 3, the maritime security unit 4, the light sign 5, the safe water area sign 6, and the plurality of light signs 11 include the imaging device 2, and detect the optical signal 7 from the light source device 1.

The blinking signal of the light source device 1 is detected from the
光源装置１には、任意の光源を用いることができるが、点滅間隔が小さく（周波数が高く）、無指向性の大出力光を放射できる光源を好適に用いることができる。
光源装置１は、光信号７を発光させるが、この信号は、バーコード型の点滅信号のコードを統一的に発行する必要があるため、政府管理下の諮問機関（ユビキタス等）に委ねる必要がある。
一例として、汎用モールス信号を高速化した符号を用い、インターネット上での個別アドレスを常時発光させることにより、詳細情報はインターネットに一元管理されたネット上から引き出すようにする。
このようなシステムは、常時運用時の負荷が少なく柔軟性が高いと考えられる。
Although any light source can be used for the light source device 1, a light source that can emit a large amount of non-directional light with a small blinking interval (high frequency) can be preferably used.
The light source device 1 emits the optical signal 7, but this signal needs to be issued to an advisory body (such as ubiquitous) under government control because it is necessary to issue a bar code type flashing signal code in a unified manner. is there.
As an example, by using a code obtained by speeding up a general-purpose Morse signal and emitting an individual address on the Internet at all times, detailed information is extracted from a network centrally managed on the Internet.
Such a system is considered to have a high flexibility and a low load during normal operation.
撮像装置２は光学レンズを備え、広視野をカバーできるビデオシステムであり、コンピュータと連動し、光学面の画素に当たる光の強弱を電気信号に置き換え、コンピュータシステムに情報を送ることができる。 The imaging device 2 is a video system that includes an optical lens and can cover a wide field of view. In conjunction with the computer, the imaging device 2 can transmit information to the computer system by replacing the intensity of light hitting the pixels on the optical surface with an electrical signal.
海上保安部４は、撮像装置２を備えた海上交通センター３や、撮像装置２を備えた灯標５等からの１に関する情報を、回線を通じて送られる電気信号１７、１８を解析して、大型船９や旅客船１０等にＡＩＳの電波信号８を通じて通報する。
また、不審船舶に対しては適当な行動を提起する。
The maritime security section 4 analyzes the
Appropriate action will be taken against suspicious vessels.
かくして、本実施例の航行船舶の個別認識システムは、特定の海域Ａを航行する個々の船舶に、各船舶固有の識別符号に基づいて短時間内に発光と消灯を繰り返す光源装置１を取り付け、該光源装置１の点滅信号を海上又は陸上に設けた撮像装置２で検出し、航行する船舶の個別認識を行うことから、例えば、原子力発電所の前面海域で操業希望のある漁船には、全船に当該光源装置１を附帯させることにより、管理側のモニター等に昼夜の区別なく識別符号の付いた有意船であることを示すことができるため、不審船がこの海域に入ってきた場合に、即座に信頼性の高い行動を起こすことが可能になる。
また、電波のチャンネルに相当する識別できる船の数は、海域を映し出す画像の画素数に匹敵することから、事実上制約なく運用することができる。
そして、主要な港の入り口にこの航行船舶の個別認識システム導入することにより、小型船を含めた出入港記録を自動化することができる。
