〈産業上の利用分野〉
本発明は海洋調査における洋上の船の位置の誘導方法に
関するものである。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a method for guiding the position of a ship on the ocean during oceanographic research.
〈従来の技術〉
海洋開発に伴う海洋調査において、流況や水温等の種々
の測定を行う場合には、洋上における調査船を、測定点
を結んだ測定ライン上を正確に誘導して、それらの測定
を行う必要がある。<Conventional technology> When performing various measurements such as flow conditions and water temperature during ocean research associated with ocean development, it is necessary to accurately guide a research vessel at sea along measurement lines connecting measurement points and to measure those measurements. Measurements need to be taken.
従って、船を正確に誘導するためには、洋上における船
の位置（船位）を正確に測定することが不可欠である。Therefore, in order to accurately guide a ship, it is essential to accurately measure the position of the ship on the ocean.
現状では、電波測位機（ＥＯＰ等）、ロランＣ１ＧＰＳ
、そして光波測距儀等の測定方法により船位を測定し、
実際の調査工事に利用している。Currently, radio positioning devices (EOP, etc.), Loran C1GPS
, and measure the ship's position using measurement methods such as a light wave rangefinder.
It is used for actual survey work.
このようにして測定された測定値は船上に集められ、緯
度、経度に変換して海図上に表示される。The measurements taken in this way are collected on board the ship, converted to latitude and longitude, and displayed on a nautical chart.
表示方法は、Ｘ−Ｙブロック−およびテレビブラウン管
に各々接続して行われ、操船の際には船長が測定ライン
と船との位置を確認しながら船を誘導している。The display method is performed by connecting to an XY block and a television cathode ray tube, and when maneuvering the ship, the captain guides the ship while checking the position of the measurement line and the ship.
く本発明が解決しようとする問題点〉
前記した従来の船位誘導方法には、特に厳密な船位精度
が要求される海底の地形調査のような場合には、次のよ
うな問題点が存在する。Problems to be Solved by the Present Invention The conventional ship position guidance method described above has the following problems, especially in cases such as seabed topography surveys that require strict ship position accuracy. .
くイ〉従来は前記の種々の測定方法によって、船位を緯
度と経度の平面上に表示した。Previously, the ship's position was displayed on a plane of latitude and longitude using the various measurement methods described above.
しかし、海面の高さは時々刻々と変化している。However, the height of sea level is constantly changing.
そのため船の海底からの高さを測定するには、従来の方
法では別に潮位を測定し、その潮位の変化に伴って船の
海底からの高さの補正を行わなければならず手数を要し
た。Therefore, in order to measure the height of a ship from the seabed, the conventional method requires measuring the tide level separately and then correcting the height of the ship from the seabed according to changes in the tide level, which is time-consuming. .
く口〉上記のように船の海底からの高さを求めるために
は、潮位を別に入手して後に両者を組み合わせて計算し
なければならない。As mentioned above, in order to calculate the height of a ship from the seabed, it is necessary to obtain the tide level separately and then calculate it by combining the two.
そのため、同位置、同時刻の船位の測定値が得られず、
船位の精度が低下し、正確な船位誘導が困難であった。As a result, measurements of the ship's position at the same location and time cannot be obtained.
The accuracy of the ship's position decreased, making it difficult to accurately guide the ship's position.
く本発明の目的〉
本発明は上記のような問題点を解決するために成された
もので、船位の緯度や経度と、陸上の基準点からの高さ
を同時に測定して、正確な船位を求め、その測定値をも
とに高精度な船位の誘導を行うことができる船位誘導方
法を提供することを目的とする。OBJECT OF THE INVENTION The present invention was made to solve the above-mentioned problems.It measures the latitude and longitude of the ship's position and the height from the reference point on land at the same time, thereby making it possible to accurately determine the ship's position. The purpose of the present invention is to provide a ship position guidance method that allows highly accurate ship position guidance based on the measured values.
く本発明の構成〉
以下、図面を参照しながら本発明の一実施例について説
明する。Configuration of the Present Invention> An embodiment of the present invention will be described below with reference to the drawings.
〈イ〉洋上の船の位置測定
本発明は第１図のように、光波測距儀１により船位を測
定する方法である。<A> Measuring the position of a ship on the ocean The present invention is a method of measuring the position of a ship using a light wave rangefinder 1, as shown in FIG.
光波測距儀１は、遠隔地から物体の位置測定を行うこと
ができる装置であり、１ ｋｒａの距離で測定精度が１
〜２ｃｍというきわめて高精度なものである。The light wave rangefinder 1 is a device that can measure the position of an object from a remote location, and has a measurement accuracy of 1 at a distance of 1 kra.
It has an extremely high precision of ~2 cm.
すなわち公知のように、陸上には光波測距［１を、船上
には反射鏡２を位置させる。That is, as is well known, a light wave ranging device [1] is placed on land, and a reflector 2 is placed on a ship.
陸上の光波測距儀１の座標と方向との関係および機械高
は、正確に測定しである。The relationship between the coordinates and the direction of the light wave range finder 1 on land, as well as the mechanical height, have been accurately measured.
従って、船上の反射鏡２からの反射光を測定し、かつ光
波測距儀１の水平角を測定するだけで船のＸＹ座標を決
定できる。Therefore, the XY coordinates of the ship can be determined simply by measuring the reflected light from the reflecting mirror 2 on the ship and by measuring the horizontal angle of the light wave range finder 1.
さらに光波測距儀１の機械高との差も測定できるから、
船上の反射鏡２の地上高も同時に決定できる。Furthermore, since it is possible to measure the difference between the mechanical height of the light wave rangefinder 1,
The ground height of the reflector 2 on the ship can also be determined at the same time.
〈口〉船位誘導方法
上記のようにして求めた測定値を、テレメータ３によっ
てテレメータ信号５に変換して船上に送信する。<Exposure> Ship position guidance method The measured values obtained as described above are converted into a telemeter signal 5 by the telemeter 3 and transmitted to the ship.
船上では地上からの測定値をすぐにディスプレイ上に投
影して、必要に応じてプリントアウトすることもできる
。Onboard the ship, measurements taken from the ground can be immediately projected onto a display and printed out if necessary.
船の責任者はこの投影点と、測定すべき予定線を比較し
、相違あれば方向を修正して正確な方向に誘導する。The person in charge of the ship compares this projected point with the planned line to be measured, and if there is a discrepancy, corrects the direction and guides the ship in the correct direction.
誘導の際には、ジャイロにより船の方位を正確に保ちつ
つ、測定ライン４上を船が航行するように誘導する。At the time of guidance, the ship is guided so that it sails on the measurement line 4 while accurately maintaining the ship's direction using a gyro.

しかし、海底の地形調査等の場合は、船の海底からの高
さも測定する必要がある。However, when surveying the topography of the ocean floor, it is necessary to also measure the height of the ship from the ocean floor.
そのため従来の方法では、船の海底からの高さを測定す
るために、別に潮位を測定して、後に潮位の測定値の変
化に伴って船の海底からの高さを補正しなければならず
手数を要した。Therefore, in conventional methods, in order to measure the height of a ship from the seabed, it is necessary to separately measure the tide level, and then correct the ship's height from the seabed in accordance with changes in the measured tide level. It took a lot of work.
ところが本発明は船位の緯度や経度と、陸上の基点から
の高さを同時にかつ高精度に測定することが可能となっ
た。However, the present invention has made it possible to measure the latitude and longitude of the ship's position and the height from the base point on land simultaneously and with high precision.
そのため、船の海底からの高さを船上で即座に求めるこ
