Description

本発明は、安全かつ精度よく船舶の喫水を計測して船舶の載荷重量を迅速に算出できる船舶の載荷重量算出システム、及び船舶の載荷重量算出方法に関する。   The present invention relates to a ship load calculation system and a ship load calculation method capable of measuring ship draft safely and accurately and calculating the ship load quickly.

船舶においては、完成した船舶を発注先に引き渡す前に喫水を計測し、その計測喫水を基に排水量計算と、この船舶が搭載可能な重量である載荷重量の計算をして、実際の載荷重量を確認している。   In the case of a ship, the draft is measured before the completed ship is delivered to the supplier, and the actual load is calculated by calculating the amount of drainage based on the measured draft and the load that is the weight that the ship can carry. Have confirmed.

この喫水の計測は、従来技術では、図６に示すような、水位計測時に水面Ｗを貫通する透明な筒状部材１１と、この筒状部材１１の下部に接続する水導入部材１２とを備えて形成された喫水計測装置１０Ｘを用いて、図７に示すように、水位計測時に、計測員Ａが小型船２０に乗って、計測対象の船舶３０に近接して、船舶３０の水面Ｗ近傍の船舶３０の舷側の外板３０ａに設けられたマークＭと水面Ｗとの間の距離Ｈを計測している。   In the prior art, this draft measurement includes a transparent tubular member 11 that penetrates the water surface W during water level measurement and a water introduction member 12 that is connected to the lower portion of the tubular member 11 as shown in FIG. As shown in FIG. 7, when the water level is measured, the measurer A gets on the small boat 20, approaches the ship 30 to be measured, and near the water surface W of the ship 30. The distance H between the mark M provided on the outer plate 30a on the shore side of the ship 30 and the water surface W is measured.

図６に示すように、この喫水計測装置１０Ｘは、筒状部材１１の上部に計測基準点となる基準部材１１ｄと、この基準部材１１ｄを基準にして下方に延びる水位計測用の目盛１１ｅ（筒状体１１ａの表面に設けられている）と、筒状体１１ａの上部に、筒状体１１ａの内部の空気が外気と流通可能でかつ、計測員Ａが指で塞ぐことができる通風孔１１ｆを設けて構成されている。また、水導入部材１２は、筒状部材１１の下部にホースクリップ１３ａで固定されるホース１２ａとこのホース１２ａの下部にホースクリップ１３ｂで固定される先端パイプ１２ｂとで構成され、この先端パイプ１２ｂに海水取り込み用の先端通水孔１２ｃと側面通水孔１２ｄを設けられている。   As shown in FIG. 6, the draft measuring device 10X includes a reference member 11d serving as a measurement reference point on the upper part of a cylindrical member 11, and a scale 11e (cylinder for measuring a water level) extending downward with reference to the reference member 11d. And the ventilation hole 11f that allows the air inside the cylindrical body 11a to circulate with the outside air and can be closed by the measurer A with a finger at the upper part of the cylindrical body 11a. Is provided. The water introduction member 12 includes a hose 12a fixed to the lower part of the cylindrical member 11 with a hose clip 13a and a tip pipe 12b fixed to the lower part of the hose 12a with a hose clip 13b. The tip pipe 12b Are provided with a tip water passage 12c and a side water passage 12d for taking in seawater.

そして、従来の喫水計測では、計測員Ａが小型船２０上で、計測対象の船舶３０と小型船２０の間に、喫水計測装置１０Ｘの水導入部材１２を水中に投入して、水の導入部分を波浪や風の影響の少ない部分まで沈めると共に、その水面Ｗ上で筒状部材１１を持ちながら、基準部材１１ｄを船舶３０の外板３０ａの喫水マーク（吃水標）Ｍの中での使用し易い喫水マークＭに合わせて、水位計測時に、通風孔１１ｆを指で塞ぐことにより、計測開始時の筒状体１１ａの内側の内部水位Ｗｉｎを固定させて、この固定された内部水位Ｗｉｎを筒状体１１ａの表面の目盛１１ｅから目視で読み取っている。   In the conventional draft measurement, the measurer A introduces the water introduction member 12 of the draft measurement device 10 </ b> X into the water between the measurement target ship 30 and the small ship 20 on the small ship 20. The reference member 11d is used in the draft mark (draft mark) M of the outer plate 30a of the ship 30 while the tubular member 11 is held on the water surface W while the portion is submerged to the portion where the influence of waves and winds is small. The internal water level Win inside the cylindrical body 11a at the start of the measurement is fixed by closing the ventilation hole 11f with a finger at the time of measuring the water level in accordance with the draft mark M that is easy to perform, and this fixed internal water level Win is fixed. It is visually read from the scale 11e on the surface of the cylindrical body 11a.

このとき、内部水位Ｗｉｎは計測場所に波があるために完全に一定にならず、変動しているので、１０回から３０回程度読み取った平均値を計測値とし、この計測値と基準部材１１ｄを合わせた喫水マークＭとから計測喫水を算出している。そして、この算出された計測喫水のデータを基に、測定対象の船舶の喫水と載荷重量の関係を示すデータを参照して、載荷重量を算出している。   At this time, since the internal water level Win is not completely constant and fluctuates due to a wave at the measurement location, the average value read about 10 to 30 times is taken as a measurement value, and this measurement value and the reference member 11d The measured draft is calculated from the draft mark M that is combined. Then, based on the calculated measurement draft data, the load amount is calculated with reference to data indicating the relationship between the draft of the ship to be measured and the load amount.

この喫水計測では、計測員Ａが水面Ｗ上に乗り出して作業性の悪い姿勢で、目視で目盛１１ｅを読み取る作業を多数回繰り返し、しかも、一隻の船舶３０で船体の船首、船体中央、船尾と、その両舷など、計６〜１０箇所程度を計測する必要があるため、作業効率が著しく悪い上に、苦労して計測した割には、計測精度が劣るという問題がある。更に、喫水計測に時間がかかるため、気象や海象の変化に遭遇し易くなると共に、計測員Ａの工数を始め、小型船２０の操船や計測員Ａの補助作業の工数が多くなり易いという問題がある。   In this draft measurement, a measurement person A gets on the water surface W and repeats the work of visually reading the scale 11e in a posture with poor workability. Further, since it is necessary to measure a total of about 6 to 10 places such as both sides, there is a problem that the working efficiency is remarkably bad and the measurement accuracy is inferior for the troublesome measurement. Furthermore, since it takes time to measure the draft, it is easy to encounter changes in weather and sea conditions, and the man-hours of the measurer A, the maneuvering of the small boat 20 and the auxiliary man-hours of the measurer A are likely to increase. There is.

この対策として、正確に垂直に保持することができるとともに船体外板の吃水標に垂直に合致でき、かつ上向きの外板形状に対しても目盛を垂直に合致させることができ、いかなる場合にも正確かつ高精度な吃水量の計測ができることを目的にして、上下に延長する目盛板に両端開口の透明管を垂設するとともに同透明管の下端に重錘を嵌合し、目盛板上端に直交して水平方向に延び先端を鋭角状に形成した支持板を固着し、かつ同支持板上縁に水平に水準器を取り付けるとともに下方に水平方向に摺動可能な支持棒を取り付けた船舶吃水計測装置が提案されている（例えば、特許文献１参照）。   As measures against this, it can be held exactly vertically, and can be vertically matched to the water mark of the hull skin, and the scale can be vertically matched to the upward skin shape. For the purpose of accurately and accurately measuring the amount of flooding, a transparent tube with both ends is suspended from the scale plate extending vertically, and a weight is fitted to the lower end of the transparent tube, and the upper end of the scale plate is fitted. A marine flooding with a support plate that extends perpendicularly and extends in the horizontal direction and has a sharp tip at the tip, and has a level attached to the upper edge of the support plate and a support rod that can slide horizontally downward A measuring device has been proposed (see, for example, Patent Document 1).

また、船舶の喫水計測器の使用上の便と計測精度を向上させることを目的に、外板の曲がりが強く水面との間が狭域となる場合でも、喫水計測器を水面に垂直に立てることができるように、喫水計測器の円筒状部を鉛直、又は上下動の調整が可能に支持して、喫水標に合わせることができて、しかも、マグネット吸着材で船体外板に吸着する喫水計測器支持装置を使用して、水位計測時に喫水計測器をマグネット吸着材で船舶の外板に固定し、ホルダーを垂直に固定した上でこのホルダーに喫水計測器を挿通させて、基準点を喫水標に当接させて円筒状部内の水面位置を計測することも提案されている（例えば、特許文献２参照）。   In addition, for the purpose of improving the convenience and measurement accuracy of ship draft measuring instruments, even when the outer plate is bent strongly and the water surface is narrow, the draft measuring instrument stands vertically to the water surface. So that the cylindrical part of the draft meter can be adjusted vertically or vertically so that it can be adjusted to the draft mark, and the draft is adsorbed on the hull skin by a magnet adsorbent. Using a measuring instrument support device, when measuring the water level, fix the draft measuring instrument to the outer skin of the ship with a magnet adsorbent, fix the holder vertically, insert the draft measuring instrument through this holder, and set the reference point. It has also been proposed to measure the position of the water surface in the cylindrical portion in contact with the draft (see, for example, Patent Document 2).

また、船側から船体に固定して海中に吊り下げたテレスコープ式ガイドパイプと、このガイドパイプ内をガイドされ先端に海面に浮かぶフロートを有する目盛ワイヤと、該目盛ワイヤを繰り出しおよび繰り込むウインチを配置し、ガイドパイプが目盛ワイヤの繰り出しに応じて繰り出されると共に、目盛ワイヤの繰りこみに応じて繰り込まれるように構成して、目盛ワイヤを繰り出しながら船舶の喫水を計測する吃水計測方法も提案されている（例えば、特許文献３参照）。   In addition, a telescopic guide pipe fixed to the hull from the ship side and suspended in the sea, a scale wire having a float that is guided in the guide pipe and floats on the sea surface, and a winch for feeding and feeding the scale wire Also proposed is a flood measurement method that measures the draft of the ship while feeding the scale wire while the guide pipe is fed according to the scale wire being fed and also being drawn according to the scale wire being fed. (For example, see Patent Document 3).

しかしながら、いずれも、計測員が目視で目盛を読み取る必要があり、作業性が悪いことと、小型船上で、外板に喫水計測器を精度よく重力方向に維持したり、固定したり、目盛ワイヤの繰り出し及び繰り込みをしたりする必要が有るので、計測員の負担が大きいという問題がある。   However, in any case, it is necessary for the measurer to visually read the scale, and the workability is poor, and on the small boat, the draft meter is accurately maintained on the outer plate in the direction of gravity, fixed, Therefore, there is a problem that the burden on the measurer is large.

なお、水位計の具体的な内容は記載されていないが、航行中の船舶の船体上の一点から海面までの距離を連続的に計測する水位計を利用する船舶の最適喫水設定装置が提案されている（例えば、特許文献４参照）。しかし、この様な航海中の喫水計測のための水位計の精度では、計測距離が長く、また、波浪の影響も大きく、必要とされる計測精度が異なり、引き渡し前に載荷重量を確認するための喫水計測の精度を満足させるには全く不十分であるので、使用できないという問題がある。   Although the specific contents of the water level gauge are not described, an optimum draft setting device for a ship using a water level gauge that continuously measures the distance from one point on the hull of the vessel being navigated to the sea surface has been proposed. (For example, see Patent Document 4). However, the accuracy of the water level gauge for measuring the draft during this voyage is because the measurement distance is long and the influence of waves is large, the required measurement accuracy is different, and the loaded load is checked before delivery. However, there is a problem that it cannot be used because it is not enough to satisfy the draft measurement accuracy.

また、上甲板上に設けられたベース部材の外端部から水中へ支持部材を垂下し、その下端部に直下の水底までの距離を計測するレーザー式測距装置と、船体の横傾斜状態での船体横断面における船体中心線と平行にレーザー光を水底へ向けて照射するレーザー光照射装置とを設けて、水底にレーザー受光器を設けて、レーザー光による計測手段の採用により、水面の影響を受けることなく船体の喫水や傾斜角を計測する船体の喫水等計測装置が提案されている（例えば、特許文献５参照）。しかしながら、この計測システムでは、装置が大掛かりになり、１隻について引き渡し前に１回計測される程度の喫水計測用としては、採用し難いという問題がある。   In addition, a laser rangefinder that measures the distance from the outer end of the base member provided on the upper deck to the water, and measures the distance from the lower end to the bottom of the water, and A laser beam irradiation device that irradiates laser beam toward the bottom of the water in parallel with the hull center line in the cross section of the hull, and a laser receiver at the bottom of the water. There has been proposed a measuring device for the draft of a hull and the like that measures the draft and the inclination angle of the hull without receiving (see, for example, Patent Document 5). However, in this measurement system, there is a problem that the apparatus becomes large, and it is difficult to adopt it for draft measurement to the extent that one ship is measured once before delivery.

本発明は、上記の状況を鑑みてなされたものであり、その目的は、従来技術の目盛り読み取り方式に比べて、電気信号処理により目盛読み取り作業を不要にすることができて、計測対象の船舶と計測員が乗っている小型船の間での水位計測の作業性を著しく向上することができ、安全かつ精度よく船舶の喫水を計測して船舶の載荷重量を迅速に算出できる船舶の載荷重量算出システム、及び船舶の載荷重量算出方法を提供することにある。   The present invention has been made in view of the above-described situation, and its purpose is to make it unnecessary to perform scale reading work by electric signal processing as compared with the conventional scale reading method, and to measure a ship to be measured. Can significantly improve the workability of the water level measurement between the small ship on which the occupant is riding, and can measure the draft of the ship safely and accurately to quickly calculate the load capacity of the ship. It is providing the calculation system and the load amount calculation method of a ship.

上記のような目的を達成するための本発明の船舶の載荷重量算出システムは、水位計測時に水面を貫通する筒状部材と、該筒状部材の下部に接続する水導入部材とを備えて、水位計測時に前記水導入部材から前記筒状部材に水を導入して、計測対象の船舶の喫水を計測する喫水計測装置を用いて、前記船舶の喫水計測を行い、この喫水計測結果を用いて前記船舶の載荷重量計算を行う船舶の載荷重量算出システムにおいて、ガイドパルス方式の水位検出センサ部を前記筒状部材に挿入して、前記水位検出センサ部で計測した結果を水位データに変換する水位計測制御部を有する水位検出器を備えた喫水計測装置と、前記船舶の載荷重量を算出するための載荷重量計算用データを入力する計算用データ入力部と、前記喫水計測装置で計測した前記水位データを統計処理して喫水データを算出する水位データ処理部と、該水位データ処理部で統計処理した前記喫水データを使用して、前記船舶の載荷重量を算出する載荷重量算出部と、前記計算用データ入力部と前記水位データ処理部と前記載荷重量算出部を制御する制御部を備え、水位計測時に前記喫水計測装置を重力方向に維持するための垂直維持機構としてジャイロ式姿勢安定器を設けると共に、前記制御部が、前記喫水計測装置で水位を計測して前記水位データを得る際に、前記ジャイロ式姿勢安定器における姿勢制御用のジャイロを回転させて、前記筒状部材を垂直状態に維持する力を与えることを特徴とする。 The load carrying amount calculation system for a ship of the present invention for achieving the above object includes a cylindrical member that penetrates the water surface at the time of water level measurement, and a water introduction member that is connected to a lower portion of the cylindrical member. At the time of water level measurement, water is introduced from the water introduction member into the tubular member, and the draft measurement device is used to measure the draft of the ship to be measured, and the draft measurement result is used. In the ship load capacity calculation system for calculating the load capacity of the ship, a water level that inserts a guide pulse type water level detection sensor into the cylindrical member and converts the result measured by the water level detection sensor into water level data. A draft measurement device equipped with a water level detector having a measurement control unit, a calculation data input unit for inputting load amount calculation data for calculating the load amount of the ship, and before measurement with the draft measurement device A water level data processing unit that statistically processes the water level data to calculate draft data, and using the draft data statistically processed by the water level data processing unit, a load amount calculation unit that calculates a load amount of the ship; and A gyro-type attitude stabilizer as a vertical maintenance mechanism for maintaining the draft measurement device in the direction of gravity when measuring the water level, comprising a control unit for controlling the calculation data input unit, the water level data processing unit, and the load amount calculation unit described above And when the control unit measures the water level with the draft measuring device and obtains the water level data, the control unit rotates the gyro for attitude control in the gyro-type attitude stabilizer to vertically position the cylindrical member. It is characterized by giving a force to maintain the state.

これらの計算用データ入力部と水位データ処理部と載荷重量算出部と、これらを制御する制御部は、現時点でのパソコン（パーソナルコンピュータ）程度の能力の携帯用のコンピュータに搭載（インストール）しておくことができるので、喫水計測時にこの携帯用のコンピュータを持ち運びながら喫水計測と載荷重量計算ができるように容易に構成することができる。   These calculation data input unit, water level data processing unit, load amount calculation unit, and control unit for controlling these are installed (installed) in a portable computer having the capability of a personal computer at the present time. Therefore, it is possible to easily configure the draft measurement and the load calculation while carrying the portable computer at the time of draft measurement.

この構成によれば、従来技術の目盛り読み取り方式に比べて、電気信号処理により目盛読み取り作業を不要にすることができて、計測対象の船舶と計測員が乗っている小型船の間での水位計測の作業性を著しく向上することができる。   According to this configuration, the scale reading work can be made unnecessary by electric signal processing as compared with the conventional scale reading method, and the water level between the ship to be measured and the small ship on which the measurer is on board is reduced. The workability of measurement can be remarkably improved.

しかも、予め行った排水量計算に基づいて用意した、計測対象の船舶の喫水と載荷重量の関係を示す載荷重量算出用データを用意し、人手を介して、この計測した喫水計測データと載荷重量算出用データを参照して載荷重量を算出していたものを、予め、計測対象の船舶の載荷重量算出用データを、船舶の載荷重量算出システムの計算用データ入力部に入力しておくことで、喫水計測装置で計測された水位データを自動的に取り込むと共に、この水位データから平均喫水等に統計処理された喫水データを自動的に算出し、予め設定されたプログラムによって瞬時に載荷重量を算出できる。そのため、載荷重量算出作業が軽減され、喫水計測作業を含む載荷重量確定作業を効率的に実施できる。   Moreover, prepared load amount calculation data indicating the relationship between the draft of the vessel to be measured and the load amount prepared based on the drainage amount calculation performed in advance is prepared, and the measured draft measurement data and the load amount calculation are performed manually. By loading the load load amount calculation data of the ship to be measured into the calculation data input part of the ship load load calculation system in advance, the load load amount calculation data of the ship that has been calculated with reference to the data for The water level data measured by the draft measuring device is automatically taken in, the draft data statistically processed to the average draft etc. is automatically calculated from this water level data, and the load amount can be calculated instantaneously by a preset program. . Therefore, the load amount calculation work is reduced, and the load amount determination work including the draft measurement work can be performed efficiently.

なお、水位検出器としては、フロート方式、電極方式、超音波方式、静電容量方式等の方式のレベルセンサがあるが、計測精度の面やメンテナンスの面等からガイドパルス方式のレベルセンサを用いる。このガイドパルス方式のレベルセンサは計測精度及びメンテナンス性が優れているので、連続計測可能なレベルセンサと、筒状部材と水導入部材を有する喫水計測装置との組み合わせに最適となる。   As the water level detector, there are float type, electrode type, ultrasonic type, electrostatic capacitance type level sensors, etc., but a guide pulse type level sensor is used in terms of measurement accuracy and maintenance. . Since this guide pulse type level sensor is excellent in measurement accuracy and maintainability, it is optimal for a combination of a level sensor capable of continuous measurement and a draft measuring device having a tubular member and a water introduction member.

また、水位計測時に前記喫水計測装置を重力方向に維持するための垂直維持機構としてジャイロ式姿勢安定器を設けると共に、前記制御部が、前記喫水計測装置で水位を計測して前記水位データを得る際に、前記ジャイロ式姿勢安定器における姿勢制御用のジャイロを回転させて、前記筒状部材を垂直状態に維持する力を与えるように構成しているので、次のような効果を奏することができる。 In addition, a gyro-type attitude stabilizer is provided as a vertical maintenance mechanism for maintaining the draft measurement device in the direction of gravity during water level measurement, and the control unit measures the water level with the draft measurement device to obtain the water level data. At this time, since the posture control gyro in the gyro-type posture stabilizer is rotated to give a force for maintaining the cylindrical member in a vertical state , the following effects can be obtained. it can.

このように構成すると、ジャイロ式姿勢安定器により、計測員が支持部材で喫水計測装置を手持ちして計測する際には、喫水計測装置の方向が重力方向を向くので、計測員の負担を大きく軽減できる。また、支持部材を計測対象の船舶の外板に一時的に取り付けて計測する場合には、ジャイロ式姿勢安定器により喫水計測装置の方向が重力方向を向いている状態で、あるいは、喫水測定時にジャイロ式姿勢安定器の稼働によりジャイロ効果で喫水計測装置の方向が重力方向を向くことができる状態で、船舶の外板に取り付けることで、喫水計測において喫水計測装置の方向を重力方向にすることができる。 When configured in this way, the gyro-type attitude stabilizer increases the burden on the measurer because the direction of the draft measurement device faces the direction of gravity when the measurer holds and measures the draft measurement device with the support member. Can be reduced. In addition, when measuring by temporarily attaching the support member to the outer plate of the ship to be measured, the gyro-type attitude stabilizer makes the direction of the draft measurement device face the direction of gravity, or during draft measurement With the gyro-type attitude stabilizer operating, the direction of the draft measuring device can be directed in the direction of gravity due to the gyro effect, and by attaching it to the outer plate of the ship, the direction of the draft measuring device is set to the direction of gravity in draft measurement. Can do.

そして、上記のような目的を達成するための本発明の船舶の載荷重量算出方法は、水位計測時に水面を貫通する筒状部材と、該筒状部材の下部に接続する水導入部材とを備えて、水位計測時に前記水導入部材から前記筒状部材に水を導入して、計測対象の船舶の喫水を計測する喫水計測装置を用いて、前記船舶の喫水計測を行い、この喫水計測結果を用いて前記船舶の載荷重量計算を行う船舶の載荷重量算出方法において、ガイドパルス方式の水位検出センサ部を前記筒状部材に挿入した前記喫水計測装置を用いて、この喫水計測装置を重力方向に維持するための垂直維持機構として設けたジャイロ式姿勢安定器における姿勢制御用のジャイロを回転させて、前記筒状部材を垂直状態に維持する力を与えた状態で、前記筒状部材の内部水面を前記水位検出センサ部で計測して水位データに変換して、この水位データを統計処理して喫水データとし、この喫水データを使用して、前記船舶の載荷重量を算出することを特徴とする方法である。 And the ship loading load amount calculation method of the present invention for achieving the above object comprises a cylindrical member penetrating the water surface at the time of water level measurement, and a water introducing member connected to the lower part of the cylindrical member. Then, water is introduced into the cylindrical member from the water introduction member at the time of water level measurement, and the draft measurement device is used to measure the draft of the ship, and the draft measurement result is obtained. In the method for calculating a load amount of a ship using the load amount calculation of the ship, the draft measurement device is arranged in the direction of gravity by using the draft measurement device in which a water level detection sensor unit of a guide pulse method is inserted into the cylindrical member. An internal water surface of the cylindrical member in a state in which a force for maintaining the cylindrical member in a vertical state is applied by rotating the gyro for posture control in a gyro-type posture stabilizer provided as a vertical maintaining mechanism for maintaining The A method for measuring the water level by detecting the water level and converting it into water level data, statistically processing the water level data to obtain draft data, and using the draft data, calculating a load amount of the ship. It is.

この方法によれば、従来技術の目盛り読み取り方式に比べて、電気信号処理により目盛読み取り作業を不要にすることができて、計測対象の船舶と計測員が乗っている小型船の間での水位計測の作業性を著しく向上することができる。しかも、予め、計測対象の船舶の載荷重量算出用データを、船舶の載荷重量算出システムの計算用データ入力部に入力しておくことで、喫水計測装置で計測された水位データを自動的に取り込むと共に、この水位データから平均喫水等に統計処理された喫水データを自動的に算出し、予め設定されたプログラムによって瞬時に載荷重量を算出できる。そのため、載荷重量算出作業が軽減され、喫水計測作業を含む載荷重量確定作業を効率的に実施できる。また、ジャイロ式姿勢安定器における姿勢制御用のジャイロを回転させて、筒状部材を垂直状態に維持する力を与えることにより、計測員が支持部材で喫水計測装置を手持ちして計測する際には、喫水計測装置の方向が重力方向を向くので、計測員の負担を大きく軽減できる。また、支持部材を計測対象の船舶の外板に一時的に取り付けて計測する場合には、ジャイロ式姿勢安定器により喫水計測装置の方向が重力方向を向いている状態で、あるいは、喫水測定時にジャイロ式姿勢安定器の稼働によりジャイロ効果で喫水計測装置の方向が重力方向を向くことができる状態で、船舶の外板に取り付けることで、喫水計測において喫水計測装置の方向を重力方向にすることができる。 According to this method, compared with the conventional scale reading method, the scale reading work can be made unnecessary by electric signal processing, and the water level between the ship to be measured and the small ship on which the measurer is on board is reduced. The workability of measurement can be remarkably improved. Moreover, the water level data measured by the draft measuring device is automatically taken in by inputting the load load amount calculation data of the ship to be measured into the calculation data input unit of the ship load amount calculation system in advance. At the same time, the draft data statistically processed to the average draft and the like is automatically calculated from the water level data, and the loaded amount can be instantaneously calculated by a preset program. Therefore, the load amount calculation work is reduced, and the load amount determination work including the draft measurement work can be performed efficiently. In addition, by rotating the gyro for attitude control in the gyro-type attitude stabilizer and applying a force to maintain the cylindrical member in a vertical state, when the measurer holds the draft measurement device with the support member and performs measurement Since the direction of the draft measurement device faces the direction of gravity, the burden on the measurer can be greatly reduced. In addition, when measuring by temporarily attaching the support member to the outer plate of the ship to be measured, the gyro-type attitude stabilizer makes the direction of the draft measurement device face the direction of gravity, or during draft measurement With the gyro-type attitude stabilizer operating, the direction of the draft measuring device can be directed in the direction of gravity due to the gyro effect, and by attaching it to the outer plate of the ship, the direction of the draft measuring device is set to the direction of gravity in draft measurement. Can do.

以下、本発明に係る実施の形態の船舶の載荷重量算出システム及び船舶の載荷重量算出方法について、図面を参照しながら説明する。   DESCRIPTION OF EMBODIMENTS Hereinafter, a ship load calculation system and a ship load calculation method according to embodiments of the present invention will be described with reference to the drawings.

図１に示すように、本発明の実施の形態の船舶の載荷重量算出システム１は、制御部４０と、この制御部４０の下にある、計算用データ入力部４１、水位データ処理部４２、及び、載荷重量算出部４３を備えて構成される。この計算用データ入力部４１は、計測対象の船舶３０（図３参照）の載荷重量を算出するための載荷重量計算用データを入力する機能を有する部分であり、水位データ処理部４１は、喫水計測装置１０で計測した水位データを統計処理して喫水データを算出する機能を有する部分であり、載荷重量算出部４３は水位データ処理部４１で統計処理した喫水データを使用して、計測対象の船舶３０の載荷重量を算出する機能を有する部分であり、制御部４０は計算用データ入力部４１と水位データ処理部４２と載荷重量算出部４３を制御する機能を有する部分である。   As shown in FIG. 1, the load amount calculation system 1 for a ship according to an embodiment of the present invention includes a control unit 40, a calculation data input unit 41, a water level data processing unit 42, which are below the control unit 40. And it is comprised including the load amount calculation part 43. The calculation data input unit 41 is a part having a function of inputting load load amount calculation data for calculating the load amount of the ship 30 (see FIG. 3) to be measured. The water level data processing unit 41 is a draft level. It is a part having a function of calculating the draft data by statistically processing the water level data measured by the measuring device 10, and the load amount calculating unit 43 uses the draft data statistically processed by the water level data processing unit 41 to The control unit 40 is a part having a function of controlling the calculation data input unit 41, the water level data processing unit 42, and the load amount calculation unit 43.

これらの計算用データ入力部４１と水位データ処理部４２と載荷重量算出部４３と、これらを制御する制御部４０は、現時点でのパソコン（パーソナルコンピュータ）程度の能力の携帯用のコンピュータに搭載（インストール）しておくことができるので、喫水計測時にこの携帯用のコンピュータを持ち運びながら喫水計測と載荷重量計算ができるように構成する。   The calculation data input unit 41, the water level data processing unit 42, the load amount calculation unit 43, and the control unit 40 for controlling them are mounted on a portable computer having the capability of a personal computer (personal computer) at the present time ( Therefore, the draft measurement and the load amount calculation can be performed while carrying the portable computer at the time of draft measurement.

また、この水位データ処理部４１に入力される水位データは、喫水計測装置１０の水位検出器１４から入力されるが、図２に示すように、この喫水計測装置１０は、水位計測時に水面Ｗを貫通する筒状部材１１と、この筒状部材１１の下部に接続する水導入部材１２とを備えて構成され、水位計測時に水導入部材１２から筒状部材１１に水を導入して、計測対象の船舶３０の喫水を計測するものであり、この筒状部材１１に、水位検出器１４のガイドパルス方式の水位検出センサ部（プローブ）１４ａを挿入して、この水位検出センサ部１４ａで計測した結果（電気信号）を水位計測制御部１４ｂで水位データ（数値を示す信号）に変換し、この水位データを水位データ処理部４２に出力するように構成される。   In addition, the water level data input to the water level data processing unit 41 is input from the water level detector 14 of the draft measurement device 10, but as shown in FIG. And a water introduction member 12 connected to the lower part of the tubular member 11. Water is introduced from the water introduction member 12 to the tubular member 11 at the time of water level measurement. The draft of the target ship 30 is measured, and a guide pulse type water level detection sensor unit (probe) 14a of the water level detector 14 is inserted into the cylindrical member 11, and measurement is performed by the water level detection sensor unit 14a. The result (electrical signal) is converted into water level data (a signal indicating a numerical value) by the water level measurement control unit 14b, and the water level data is output to the water level data processing unit 42.

この筒状部材１１は、波浪や風の影響を受け難い水深まで垂らした水導入部材１２から水を導入することにより、外側の水面Ｗが波浪や風の影響で上下に移動するのに対して、筒状部材１１の内側の内部水面Ｗｉｎの上下の移動を少なくするためのものである。この内部水面Ｗｉｎの水位を筒状部材１１の内部に挿入した水位検出センサ部１４ａで連続的に検出して平均値を算出することにより、より高い精度で水位計測できる。   The cylindrical member 11 is moved up and down due to the influence of waves and winds by introducing water from the water introduction member 12 suspended to a depth that is not easily affected by waves and winds. This is to reduce the vertical movement of the internal water surface Win inside the cylindrical member 11. The water level can be measured with higher accuracy by continuously detecting the water level of the internal water surface Win with the water level detection sensor unit 14a inserted into the cylindrical member 11 and calculating the average value.

この筒状部材１１は、アクリル製などの透明な円筒等で形成された筒状体１１ａの上部にＳＵＳ製の上部キャップ１１ｂが、下部にＳＵＳ製の下部キャップ１１ｃがそれぞれ設けられて構成されている。また、筒状体１１ａの透明な円筒部分の表面には基準部材１１ｄを基準点にして下方に延びる水位計測用の目盛１１ｅが設けられる。さらに、上部キャップ１１ｂには、計測基準点となる基準部材１１ｄと、筒状体１１ａの内側の空気が外気に流通可能な通風孔１１ｆが設けられる。   The cylindrical member 11 is configured by providing an upper cap 11b made of SUS and a lower cap 11c made of SUS at the upper part of a cylindrical body 11a formed of a transparent cylinder such as acrylic. Yes. Further, a scale 11e for water level measurement extending downward with the reference member 11d as a reference point is provided on the surface of the transparent cylindrical portion of the cylindrical body 11a. Further, the upper cap 11b is provided with a reference member 11d serving as a measurement reference point and a ventilation hole 11f through which air inside the cylindrical body 11a can flow to the outside air.

この筒状体１１ａの透明な円筒の内径は５０ｍｍ以上で、且つ、１００ｍｍ以下とすることが好ましい。５０ｍｍよりも小さくすると、ガイドパルス方式のレベルセンサで形成される水位検出器１４の計測精度を高く維持できなくなる可能性が生じ、１００ｍｍより大きくすると、水位計測時における運搬や計測中の保持の問題や計測対象の船舶３０の外板への取り付け作業や取り外し作業がし難くなるという問題が生じる。また、筒状部材１１の長さは、喫水計測場所における計測時の水位変動の大きさや市販のレベルセンサの水位検出器１４の水位検出センサ部１４ａのプローブ長さにもよるが、５０ｃｍ〜１００ｃｍ程度とするのが好ましい。   The inner diameter of the transparent cylinder of the cylindrical body 11a is preferably 50 mm or more and 100 mm or less. If it is smaller than 50 mm, there is a possibility that the measurement accuracy of the water level detector 14 formed by the level sensor of the guide pulse system cannot be maintained high. If it is larger than 100 mm, there is a problem of transportation during water level measurement and retention during measurement. In addition, there is a problem in that it is difficult to attach or remove the measurement target ship 30 to or from the outer plate. Moreover, although the length of the cylindrical member 11 is based on the magnitude | size of the water level fluctuation | variation at the time of measurement in a draft measurement place, and the probe length of the water level detection sensor part 14a of the water level detector 14 of a commercially available level sensor, it is 50 cm-100 cm. It is preferable to set the degree.

また、通風孔１１ｆは、水位検出器１４で計測する時は、内部水面Ｗｉｎが上下移動しても連続計測が可能なので、水位計測時に塞いで通気を遮断する必要はないが、万一、水位検出器１４が故障した場合でも、目視で喫水計測を行えるように、計測員Ａが通風を一時的に遮断できるように構成することが好ましい。そのため、例えば、計測員Ａが通風穴１１ｆを指などで塞ぎ易いように、指先で塞げる大きさと位置に通風孔１１ｆを設けたり、通風孔１１ｆに通風チューブ（図示しない）を設けて、この通風チューブの口を塞いだり、この通風チューブの一部を折り曲げたり、この通風チューブに設けたバルブを閉めたりできるように構成する。   In addition, when measuring with the water level detector 14, the ventilation hole 11f can be continuously measured even if the internal water surface Win moves up and down, so it is not necessary to block the ventilation and block the ventilation when the water level is measured. Even when the detector 14 breaks down, it is preferable that the measurement staff A can temporarily block the ventilation so that the draft measurement can be performed visually. Therefore, for example, in order to make it easy for the measurer A to close the ventilation hole 11f with a finger or the like, the ventilation hole 11f is provided in a size and position where the fingertip can be closed, or a ventilation tube (not shown) is provided in the ventilation hole 11f. The vent tube is closed, the vent tube is partially bent, or a valve provided on the vent tube is closed.

基準部材１１ｄは、この喫水測定具１０における計測基準点となる高さの位置を示すものであり、図４に示すような水位計測時に、計測対象の船舶３０の外板３０ａに設けられた喫水マークＭに当接させる必要があるので、水平方向に例えばテレスコープ構造などで伸縮できるようにしたり、筒状部材１１の円筒の軸周りにある程度の角度範囲で回動可能に構成したりすることが好ましい。また、基準部材１１ｄは円筒部材１１の円筒の軸と直角になるよう設けられ、水位計測時には、基準部材１１ｄを水平に、円筒部材１１を垂直方向（重力方向）に維持することが重要であるので、基準部材１１ｄの水平を見るために水準器を設けたり、円筒部材１１の垂直度合いを見るために重錘を設けたりすることが好ましい。   The reference member 11d indicates the position of the height serving as a measurement reference point in the draft measuring instrument 10, and the draft provided on the outer plate 30a of the ship 30 to be measured at the time of water level measurement as shown in FIG. Since it is necessary to abut on the mark M, it can be expanded and contracted in the horizontal direction by, for example, a telescope structure, or configured to be rotatable around a cylindrical axis of the cylindrical member 11 within a certain angle range. Is preferred. In addition, the reference member 11d is provided so as to be perpendicular to the axis of the cylinder of the cylindrical member 11, and when measuring the water level, it is important to maintain the reference member 11d horizontally and the cylindrical member 11 in the vertical direction (gravity direction). Therefore, it is preferable to provide a level to see the level of the reference member 11d, or to provide a weight to see the vertical degree of the cylindrical member 11.

また、水導入部材１２は、筒状部材１１の下部の下部キャップ１１ｃにＳＵＳ製のホースクリップ１３ａで固定されるビニール製のホース１２ａとこのホース１２ａの下部にＳＵＳ製のホースクリップ１３ｂで固定されるアクリル製の透明な先端パイプ１２ｂとで構成され、この先端パイプ１２ｂに海水取り込み用の先端通水孔１２ｃと側面通水孔１２ｄを設けて構成される。この水導入部材１２は、波浪や風の影響の少ない水深から水を筒状部材１１の内部に導入して、筒状部材１１の外部の水面Ｗの変動に比べて、内部水面Ｗｉｎの変動を少なくするためのものであるので、ある程度の水深に届くように、ホース１２ａの長さは、１ｍ〜３ｍ程度、先端パイプ１２ｂの長さは０．１ｍ〜０．３ｍ程度とするのが好ましい。また、水位計測時に、迅速に筒状部材１１の内部に水が導入できるように、ホース１２ａと先端パイプ１２ｂの内径は、１ｃｍφ〜３ｃｍφ程度とするのが好ましい。   The water introduction member 12 is fixed to the lower cap 11c of the lower part of the cylindrical member 11 by a SUS hose clip 13a and a vinyl hose 12a fixed to the lower part of the hose 12a by a SUS hose clip 13b. A transparent tip pipe 12b made of acrylic, which is provided with a tip water hole 12c and a side water hole 12d for taking in seawater in the tip pipe 12b. This water introduction member 12 introduces water into the cylindrical member 11 from the depth of the water that is less affected by waves and winds, and the fluctuation of the internal water surface Win is compared with the fluctuation of the water surface W outside the cylindrical member 11. The length of the hose 12a is preferably about 1 m to 3 m and the length of the tip pipe 12b is preferably about 0.1 m to 0.3 m so as to reach a certain depth. Moreover, it is preferable that the inner diameters of the hose 12a and the tip pipe 12b are about 1 cmφ to 3 cmφ so that water can be quickly introduced into the cylindrical member 11 when measuring the water level.

また、水位検出器１４には、フロート方式、電極方式、超音波方式、静電容量方式等の方式のレベルセンサを用いずに、水位検出センサ部（プローブ）１４ａと水位計測制御部（コントローラ）１４ｂとから構成されるガイドパルス方式のレベルセンサを用いる。つまり、水位検出器１４に、このガイドパルス方式のレベルセンサを用いると計測精度の面やメンテナンスの面等から、この喫水計測装置１０により適合するので、水位検出センサ部１４ａで計測した結果を信号出力する喫水計測装置１０を実用化できる。   The water level detector 14 does not use a level sensor such as a float method, an electrode method, an ultrasonic method, or a capacitance method, but a water level detection sensor unit (probe) 14a and a water level measurement control unit (controller). 14b is used as a level sensor of the guide pulse type. In other words, if this guide pulse type level sensor is used for the water level detector 14, it is more suitable for the draft measuring device 10 from the aspect of measurement accuracy, maintenance, etc., so the signal measured by the water level detection sensor unit 14a is a signal. The draft measuring device 10 to output can be put into practical use.

このガイドパルス方式の検出原理は、制御部１４ｂから細長い形状の水位検出センサ部１４ａ上にパルス信号を伝達し、液面（内部水面Ｗｉｎ）で反射されるパルス信号を受信して、パルス信号の送信から受信までの時間から距離（レベル）を計測するものであり、検出距離をＬ、送信から受信までの時間をＴ、光速をＣとすると、検出距離はＬ＝（１／２）×Ｔ×Ｃの計算式から求められる。この検出距離Ｌを補正して基準部材１１ｄの基準位置（例えば、上面）と液面（内部水面Ｗｉｎ）との距離Ｈを算出する。なお、このガイドパルス式レベルセンサは、市販されており、容易に入手可能である。   The detection principle of this guide pulse method is that the pulse signal is transmitted from the control unit 14b to the elongated water level detection sensor unit 14a, the pulse signal reflected on the liquid surface (internal water surface Win) is received, and the pulse signal The distance (level) is measured from the time from transmission to reception. If the detection distance is L, the time from transmission to reception is T, and the speed of light is C, the detection distance is L = (1/2) × T. It is calculated | required from the formula of * C. The detection distance L is corrected to calculate a distance H between the reference position (for example, the upper surface) of the reference member 11d and the liquid surface (internal water surface Win). This guide pulse type level sensor is commercially available and can be easily obtained.

この支持部材１５は、装置の故障等の万一の場合に、計測員Ａが喫水計測装置１０を手持ちして計測する場合には、手持ちする部分となり、また、計測員Ａが目視し易い部分となるので、基準部材１１ｄを水平に保持するために使用する水準器をこの支持部材１５に設けることが好ましい。   This support member 15 is a part to be held by the measurer A in the event of an instrument failure or the like, and is a part that the measurer A can easily view. Therefore, it is preferable to provide the support member 15 with a level used to hold the reference member 11d horizontally.

また、機器重心調整機構として、図２に示すような、筒状部材１１の下方の部位、例えば、下部キャップ１１ｃに、重心調整用錘１６を配置できるように構成する。これにより、重心を下にして、喫水計測装置１０を持ったりするときに、喫水計測装置１０が垂直方向を保ち易くなる。この重心調整用錘１６はリング形状の部材を半割に分解可能とすることで、容易に取り付けや取り外しができるようにすることができる。   Further, the apparatus center-of-gravity adjustment mechanism is configured such that the center-of-gravity adjustment weight 16 can be disposed on a portion below the cylindrical member 11, for example, the lower cap 11c, as shown in FIG. This makes it easier for the draft measurement device 10 to maintain the vertical direction when holding the draft measurement device 10 with the center of gravity down. The center-of-gravity adjustment weight 16 can be easily attached and detached by disassembling the ring-shaped member in half.

また、特に図示しないが、筒状部材１１の下方の部位、又は、水導入部材１２の一部に錘を下げられるフック機構やロック機構を設けたり、筒状部材１１又は水導入部材１２一部を磁性体で形成して、磁石の重心調整用錘１６を磁力により付着できる構造にしたり、筒状部材１１に水位調整可能なバラストタンクを設けたりすることでも、容易に機器重心調整機構を構成できる。   In addition, although not particularly illustrated, a hook mechanism or a lock mechanism for lowering the weight is provided at a part below the cylindrical member 11 or a part of the water introduction member 12, or a part of the cylindrical member 11 or the water introduction member 12 is provided. The center of gravity adjustment mechanism of the device can be easily configured by forming a magnetic body and making the structure capable of attaching the weight 16 for adjusting the center of gravity of the magnet by a magnetic force, or providing a cylindrical member 11 with a ballast tank capable of adjusting the water level. it can.

更に、喫水計測装置１０に、この喫水計測装置１０を水位計測時に支持するための支持部材１５と、筒状部材１１を予め設定した水位計測位置まで沈めた時に、支持部材１５に加わる重量又は浮力を調整するための浮力調整機構を設ける。   Furthermore, the weight or buoyancy applied to the support member 15 when the draft measurement device 10 is sunk to the preset water level measurement position and the support member 15 for supporting the draft measurement device 10 during the water level measurement. A buoyancy adjustment mechanism is provided for adjusting the angle.

この浮力調整機構として、図２に示すように、浮力調整用浮体１７を水面Ｗの近くに配置できるように構成する。この浮力調整用浮体１７により、喫水計測装置１０を計測時において、浮かんだ状態にすると共に、喫水計測装置１０の浮心を上にして、機器重心調整機構と同様に、喫水計測装置１０が垂直方向を保ち易する。   The buoyancy adjustment mechanism is configured such that the buoyancy adjustment floating body 17 can be disposed near the water surface W as shown in FIG. The buoyancy adjustment floating body 17 causes the draft measurement device 10 to be in a floating state at the time of measurement, and with the buoyancy of the draft measurement device 10 up, the draft measurement device 10 is vertical as in the device center-of-gravity adjustment mechanism. Easy to keep direction.

この浮力調整用浮体１７はリング形状の部材を半割に分解可能とすることで、容易に取り付けや取り外しができるようにすることができる。また、筒状部材１１又は水導入部材１２一部を磁性体で形成して、浮力調整用浮体１７に設けた磁石を磁力により付着できる構造にしたりすることでも、容易に浮力調整機構を構成できる。   The buoyancy adjusting floating body 17 can be easily attached and detached by disassembling the ring-shaped member in half. Also, the buoyancy adjustment mechanism can be easily configured by forming a part of the cylindrical member 11 or the water introduction member 12 with a magnetic body and making the magnet provided on the buoyancy adjustment floating body 17 adhere by magnetic force. .

更に、水位計測時に喫水計測装置１０を重力方向に維持するための垂直維持機構としてジャイロ式姿勢安定器１８を設けて構成する。錘を喫水計測装置１０の筒状部材１１の下部に取り付ける単純で簡単な機構でも垂直維持効果があるが、垂直維持能力を大きくしようとすると重量が大きくなり、喫水計測装置１０を中性浮力に保つことが困難となる上に、常時垂直になる方向に力が作用するので、取り扱い中のバランスが悪く、計測員Ａの負担が大きくなる。そのため、水位計測時に筒状部材１１の水面Ｗより上になる部分にジャイロ式姿勢安定器１８を取り付ける。   Further, a gyro-type attitude stabilizer 18 is provided as a vertical maintaining mechanism for maintaining the draft measuring device 10 in the direction of gravity during water level measurement. Even a simple and simple mechanism for attaching the weight to the lower part of the tubular member 11 of the draft measuring device 10 has the effect of maintaining the vertical. However, if the ability to maintain the vertical is increased, the weight increases and the draft measuring device 10 is made to have a neutral buoyancy. In addition to being difficult to maintain, the force is always applied in the vertical direction, so the balance during handling is poor and the burden on the measurer A increases. Therefore, the gyro attitude stabilizer 18 is attached to a portion of the tubular member 11 that is above the water surface W when the water level is measured.

この場合は、ジャイロ式姿勢安定器１８のモーター１８ａでジャイロを回転させている間だけ、垂直維持機能が発揮され、計測前後ではジャイロ効果を停止させることができるので、取り扱いが著しく容易となる。また、ジャイロの回転数でジャイロ効果による垂直維持機能の大きさを変更できるので、垂直維持機構の重量の増加を防止でき、浮力調整機構への影響を小さくすることができる。   In this case, the vertical maintaining function is exhibited only while the gyro is rotated by the motor 18a of the gyro attitude stabilizer 18, and the gyro effect can be stopped before and after the measurement, so that the handling becomes remarkably easy. Further, since the size of the vertical maintenance function due to the gyro effect can be changed by the rotational speed of the gyro, an increase in the weight of the vertical maintenance mechanism can be prevented, and the influence on the buoyancy adjustment mechanism can be reduced.

更に、支持部材１５を計測対象の船舶３０の外板３０ａに一時的に固定するための固定部材１９を設ける。それと共に、支持部材１５に、水位計測の間、固定部材１９と喫水計測装置１０との間の角度が自由に変化できるフレキシブルジョイント（自由継手）１５ａを設けて構成する。   Furthermore, a fixing member 19 for temporarily fixing the support member 15 to the outer plate 30a of the ship 30 to be measured is provided. At the same time, the support member 15 is provided with a flexible joint (free joint) 15a that can freely change the angle between the fixing member 19 and the draft measurement device 10 during the water level measurement.

この固定部材１９としては、一時的に外板３０ａに固定できればよいので、マグネットで吸着するものや、吸盤で吸着するものや、粘着材を介して粘着するものなどを用いることができる。また、フレキシブルジョイント１５ａとしては、固定対象の外板３０ａの形状にもよるが、一回転方向が自由回転の場合にはヒンジ（回転軸）で構成でき、多方向自由回転の場合には、自在継手（ユニバーサルジョイント）や球状継手などを用いることができる。   Since the fixing member 19 only needs to be temporarily fixed to the outer plate 30a, it is possible to use a member that is attracted by a magnet, a member that is attracted by a suction cup, a member that adheres via an adhesive material, or the like. In addition, the flexible joint 15a can be configured by a hinge (rotating shaft) when the rotation direction is free rotation, and can be freely selected in the case of multi-direction free rotation, depending on the shape of the outer plate 30a to be fixed. A joint (universal joint) or a spherical joint can be used.

また、固定部材１９は、固定可能な外板３０ａの形状ができるだけ広い方が便利であるので、固定部材１９に伸縮構造や回動構造を設けて、外板３０ａに当接する部分と、支持部材１５との相対位置の関係を、固定対象の外板３０ａの形状に応じてできるだけ自由に変更できるように構成することが好ましい。   Further, since it is convenient for the fixing member 19 to have as wide a shape as possible for the outer plate 30a that can be fixed, a portion that is provided with an expansion / contraction structure or a rotating structure on the fixing member 19 to contact the outer plate 30a, It is preferable that the relative position relationship with 15 can be changed as freely as possible according to the shape of the outer plate 30a to be fixed.

この喫水測定装置１０によれば、筒状部材に挿入したガイドパルス方式の水位検出センサ部１４ａで計測した結果を水位計測制御部１４ｂで水位データに変換する水位検出器を用いて喫水計測するので、従来技術の目盛り読み取り方式に比べて、電気信号処理できて目盛読み取り作業を不要にすることができて、計測対象の船舶３０と計測員Ａが乗っている小型船２０の間での水位計測の作業性を著しく向上することができる。   According to the draft measuring device 10, since the result measured by the guide pulse type water level detection sensor unit 14a inserted in the cylindrical member is measured using a water level detector that converts the result into water level data by the water level measurement control unit 14b. Compared with the scale reading method of the prior art, the electric signal processing can be performed and the scale reading work can be made unnecessary, and the water level measurement between the ship 30 to be measured and the small ship 20 on which the measurer A is on board is possible. The workability can be significantly improved.

また、浮力調整機構の浮力調整浮体１７により、喫水測定装置１０が中性浮力とすることができるので、喫水測定装置１０を計測対象の船舶３０の外板３０ａに取り付けたり、取り外したりする場合に、計測員Ａの負担を著しく軽減でき、また、外板３０ａに固定部材１９で固定している間も重力も浮力も殆ど力が掛らない状態になっているので、この固定部材１９や支持部材１５の構造を単純化したり、小型化したりすることができる。   Moreover, since the draft measurement apparatus 10 can be made into neutral buoyancy by the buoyancy adjustment floating body 17 of a buoyancy adjustment mechanism, when attaching and removing the draft measurement apparatus 10 to the outer plate 30a of the ship 30 to be measured. The load on the measurer A can be remarkably reduced, and while the fixing member 19 is fixed to the outer plate 30a, neither gravity nor buoyancy is applied. The structure of the member 15 can be simplified or downsized.

ジャイロ式姿勢安定器１８を用いるので、喫水計測の際に、このジャイロ式姿勢安定器１８の垂直維持機能により、筒状部材１１を自動的に垂直方向にすることができる。また、垂直維持機能を作用させながら、喫水測定装置１０の外板３０ａへの取り付け作業を行う場合には、筒状部材１１を垂直方向に維持したまま、固定部材１９を外板３０ａに取り付けるので、固定部材１９を外板３０ａに取り付けた後で、筒状部材１１を垂直方向に変更できないことが分かって再度取り付け作業を行うというような作業ミスを回避することができる。   Since the gyro type attitude stabilizer 18 is used, the cylindrical member 11 can be automatically set in the vertical direction by the vertical maintaining function of the gyro attitude stabilizer 18 at the time of draft measurement. In addition, when performing the work of attaching the draft measuring device 10 to the outer plate 30a while operating the vertical maintenance function, the fixing member 19 is attached to the outer plate 30a while maintaining the cylindrical member 11 in the vertical direction. Then, after attaching the fixing member 19 to the outer plate 30a, it is possible to avoid an operation error such that the cylindrical member 11 cannot be changed in the vertical direction and the attaching operation is performed again.

更に、フレキシブルジョイント１５ａの効果で、正確に筒状部材１１が垂直方向になるように固定部材１９を外板３０ａに取り付けなくても、ジャイロ式姿勢安定器１８の垂直維持機能により、喫水計測装置１０の筒状部材１１の方向が重力方向を向くので、固定部材１９を外板３０ａに適当な角度範囲で取り付ければよく、喫水計測装置１０の固定部材１９で計測対象の船舶３０の外板３０ａに取り付けるときの計測員の負担を著しく軽減でき、また、喫水計測の精度を向上することができる。   Further, due to the effect of the flexible joint 15a, the draft measuring device can be obtained by the vertical maintaining function of the gyro-type posture stabilizer 18 without attaching the fixing member 19 to the outer plate 30a so that the tubular member 11 is accurately in the vertical direction. Since the direction of the ten cylindrical members 11 is directed in the direction of gravity, the fixing member 19 may be attached to the outer plate 30a within an appropriate angle range, and the outer plate 30a of the ship 30 to be measured by the fixing member 19 of the draft measuring device 10. It is possible to remarkably reduce the burden on the measurer when attaching to the water, and to improve the accuracy of draft measurement.

次に、本発明の実施の形態の船舶の載荷重量算出方法について、図３及び図４を参照しながら説明する。この船舶の載荷重量算出方法は、例えば、上記の実施の形態の船舶の載荷重量算出システム１を用いて、計測対象の船舶３０の載荷重量を算出する方法である。   Next, a method for calculating the load amount of the ship according to the embodiment of the present invention will be described with reference to FIGS. This ship load amount calculation method is, for example, a method of calculating the load load amount of the ship 30 to be measured using the ship load amount calculation system 1 of the above-described embodiment.

この船舶の載荷重量算出方法では、図４に示すように、最初に、ステップＳ１０で、予め計算された測定対象の船舶３０の載荷重量計算用データを、船舶の載荷重量算出システム１の計算用データ入力部４１に入力する。   In this ship load amount calculation method, as shown in FIG. 4, first, in step S10, the load load amount calculation data of the ship 30 to be measured that has been calculated in advance is used for calculation by the ship load load amount calculation system 1. Input to the data input unit 41.

次のステップＳ２０で、計測対象の船舶３０の喫水計測位置における喫水計測と水位データの取り込みを行う。   In the next step S20, the draft measurement at the draft measurement position of the ship 30 to be measured and the water level data are taken in.

このステップＳ２０では、図５に示すように、ステップＳ２１で喫水計測を開始する前の喫水計測の準備作業を行う。この喫水計測の準備作業としては、水位検出器１４を筒状部材１１にセットしたり、筒状部材１１を予め設定した水位計測位置まで沈めた時に、支持部材１５に加わる重量又は浮力が、ほぼゼロの中性浮力となるように、機器重心調整機構の重心調整用錘１６の重量を調整したりする。また、ジャイロ式姿勢安定器１８の垂直維持機能が正常に機能するか確認する。   In this step S20, as shown in FIG. 5, preparation work for draft measurement before starting draft measurement in step S21 is performed. As preparation work for this draft measurement, when the water level detector 14 is set on the cylindrical member 11 or when the cylindrical member 11 is submerged to a preset water level measurement position, the weight or buoyancy applied to the support member 15 is almost equal. The weight of the center-of-gravity adjustment weight 16 of the device center-of-gravity adjustment mechanism is adjusted so that the neutral buoyancy is zero. Moreover, it is confirmed whether the vertical maintenance function of the gyro attitude stabilizer 18 functions normally.

次のステップＳ２２では、図３に示すように、計測員Ａが小型船２０に乗り込んで、計測対象の船舶３０の喫水計測位置に移動して、計測員Ａが小型船２０上で、計測対象の船舶３０と小型船２０の間に、喫水計測装置１０の水導入部材１２を水中に投入する。それと共に、その水面Ｗ上で、基準部材１１ｄを船舶３０の外板３０ａに設けられた喫水マークＭの中での使用し易い喫水マークＭに合わせて、固定部材１９により、電磁石の磁力や吸盤力や粘着力を利用して喫水計測装置１０を外板３０ａに一時的に取り付ける。   In the next step S22, as shown in FIG. 3, the measurer A gets into the small ship 20 and moves to the draft measurement position of the ship 30 to be measured. The water introduction member 12 of the draft measurement device 10 is put into the water between the ship 30 and the small ship 20. At the same time, on the water surface W, the reference member 11d is aligned with the draft mark M that is easy to use in the draft mark M provided on the outer plate 30a of the ship 30. The draft measuring device 10 is temporarily attached to the outer plate 30a using force or adhesive force.

また、ジャイロ式姿勢安定器１８の垂直維持機能を、取り付け前又は取り付け後に作用させて、筒状部材１１を垂直方向に維持する。   Further, the vertical maintaining function of the gyro-type posture stabilizer 18 is applied before or after the attachment, so that the cylindrical member 11 is maintained in the vertical direction.

その後、ステップＳ２３で、水位検出器１４の計測スイッチ（図示しない）を入れて連続的に水位計測を行う。この水位計測時に、通風孔１１ｆを閉塞する必要はなく、計測中の筒状部材１１の内側の内部水位Ｗｉｎの変動をそのまま連続的に水位計測して、計測スイッチを切る。水位計測と同時に、又は、水位計測後に、この水位計測した水位データを有線又は無線等により送信し、水位データ処理部４１に取り込む。   Thereafter, in step S23, a measurement switch (not shown) of the water level detector 14 is turned on to continuously measure the water level. At the time of this water level measurement, it is not necessary to close the ventilation hole 11f, the fluctuation of the internal water level Win inside the cylindrical member 11 being measured is continuously measured as it is, and the measurement switch is turned off. Simultaneously with the water level measurement or after the water level measurement, the water level data obtained by measuring the water level is transmitted by wire or wireless and taken into the water level data processing unit 41.

このステップＳ２３の水位計測を終了したら、ステップＳ２４で、ジャイロ式姿勢安定器１８の垂直維持機能を無効にしてから、電磁石の電流を切るなどして、喫水計測装置１０を取り外す。そして、この部位における喫水計測を終了し、計測員Ａが小型船２０上に、喫水計測装置１０を収容する。   When the water level measurement in step S23 is completed, in step S24, the draft maintaining device 10 is removed by disabling the vertical maintenance function of the gyro attitude stabilizer 18 and then turning off the electromagnet current. And the draft measurement in this site | part is complete | finished and the measurement person A accommodates the draft measurement apparatus 10 on the small ship 20. FIG.

そして、次のステップＳ２５で、全ての喫水計測位置における喫水計測を終了したか否かを判定し、終了していない場合は（ＮＯ）、次の喫水計測位置に移動し、ステップＳ２２〜ステップＳ２４を繰り返して同様の喫水計測を行う。順次、これを繰り返して、計測対象の船舶３０の喫水計測位置の全てにおける喫水計測を終了した場合は（ＹＥＳ）、ステップＳ２６に行き、喫水計測の終了作業を行い、図４のステップＳ３０に行く。   Then, in the next step S25, it is determined whether or not the draft measurement has been completed at all the draft measurement positions. If not completed (NO), the process moves to the next draft measurement position, and steps S22 to S24 are performed. Repeat the same process to measure the draft. If this is sequentially repeated and the draft measurement at all the draft measurement positions of the ship 30 to be measured is completed (YES), the process goes to step S26, the draft measurement is finished, and the process goes to step S30 in FIG. .

この喫水計測の終了作業としては、小型船２０を元の場所に戻して、計測員Ａは喫水計測装置１０を持って下船して、水位検出器１４を筒状部材１１から取り外したり、機器重心調整機構の重心調整用錘１６を外したりする。なお、水位検出器１４が水位計測した水位データを記憶保持できる場合は、喫水計測場所毎に水位計測した水位データを有線又は無線等により送信する必要はなく、全部の喫水計測位置における水位計測を完了した後に、このステップＳ２６で、水位データ処理部４１に取り込めばよい。   As the completion of the draft measurement, the small boat 20 is returned to its original location, and the measurer A gets off with the draft measurement device 10 to remove the water level detector 14 from the cylindrical member 11 or the center of gravity of the equipment. The center-of-gravity adjustment weight 16 of the adjustment mechanism is removed. In addition, when the water level data measured by the water level detector 14 can be stored, it is not necessary to transmit the water level data measured for each draft measurement location by wire or wireless, and the water level measurement at all draft measurement positions is possible. After the completion, in step S26, the water level data processing unit 41 may be loaded.

図４のステップＳ３０では、喫水計測装置１０で計測した水位データを水位データ処理部４１で統計処理して喫水データを算出する。この統計処理では、適当な間隔でサンプリングした水位データから水位の変動周期を求め、この変動周期の正数倍の期間の水位データの平均値を求めて喫水データとする。   In step S30 of FIG. 4, the water level data measured by the draft measuring device 10 is statistically processed by the water level data processing unit 41 to calculate draft data. In this statistical process, the fluctuation cycle of the water level is obtained from the water level data sampled at an appropriate interval, and the average value of the water level data for a period that is a positive multiple of this fluctuation cycle is obtained as draft data.

そして、次のステップＳ４０では、水位データ処理部４１で統計処理した喫水データを使用して、載荷重量算出部４３で計測対象の船舶３０の載荷重量を算出する。この載荷重量の算出に際しては、ステップＳ１０で計算用データ入力部４１に入力した測定対象の船舶３０の載荷重量計算用データを用いて、喫水データからこの測定対象の船舶３０の載荷重量を算出する。   Then, in the next step S40, using the draft data statistically processed by the water level data processing unit 41, the load amount calculating unit 43 calculates the load amount of the ship 30 to be measured. In calculating the load amount, the load amount of the ship 30 to be measured is calculated from the draft data using the load load calculation data of the ship 30 to be measured input to the calculation data input unit 41 in step S10. .

この方法によれば、従来技術の目盛り読み取り方式に比べて、電気信号処理により目盛読み取り作業を不要にすることができて、計測対象の船舶３０と計測員Ａが乗っている小型船２０の間での水位計測の作業性を著しく向上することができる。しかも、予め、計測対象の船舶３０の載荷重量算出用データを、船舶の載荷重量算出システムの計算用データ入力部４１に入力しておくことで、喫水計測装置１０で計測された水位データを自動的に取り込むと共に、この水位データから平均喫水等に統計処理された喫水データを自動的に算出し、予め設定されたプログラムによって瞬時に載荷重量を算出できる。そのため、載荷重量算出作業が軽減され、喫水計測作業を含む載荷重量確定作業を効率的に実施できる。   According to this method, compared with the conventional scale reading method, the scale reading operation can be made unnecessary by electric signal processing, and between the ship 30 to be measured and the small ship 20 on which the measurer A is on board. The workability of water level measurement in can be improved significantly. Moreover, the water level data measured by the draft measuring device 10 is automatically obtained by inputting the load load amount calculation data of the ship 30 to be measured into the calculation data input unit 41 of the ship load amount calculation system in advance. The draft data statistically processed to the average draft and the like are automatically calculated from the water level data, and the load amount can be instantaneously calculated by a preset program. Therefore, the load amount calculation work is reduced, and the load amount determination work including the draft measurement work can be performed efficiently.

更に、この船舶の載荷重量算出方法において、喫水計測装置１０を複数用いて、計測対象の船舶３０の喫水計測時に、計測対象の船舶３０の複数個所の水位計測部位にそれぞれ喫水計測装置１０を取り付けて、この取り付けた複数の喫水計測装置１０で複数個所における喫水を同時計測すると、複数個所における喫水を同時計測することができ、その後、順次複数の喫水計測装置１０を回収して廻ることにより、迅速に喫水計測を終了できる。   Further, in this ship load amount calculation method, the draft measurement device 10 is attached to each of the plurality of water level measurement parts of the measurement target ship 30 at the time of draft measurement of the measurement target ship 30 using a plurality of draft measurement devices 10. Thus, when the drafts at a plurality of locations are simultaneously measured by the plurality of draft measurement devices 10 attached, the drafts at the plurality of locations can be simultaneously measured, and then the plurality of draft measurement devices 10 are sequentially collected and rotated. The draft measurement can be completed quickly.

この同時計測では、測定前に順次喫水計測装置１０を喫水計測位置に取り付けて、取り付けた後に、例えば、タイマー又は計測開示信号の発信により、水位計測を開始させ、タイマー又は計測停止信号の発信により、水位計測を停止させる。   In this simultaneous measurement, the draft measurement device 10 is sequentially attached to the draft measurement position before measurement, and after being attached, for example, the water level measurement is started by sending a timer or measurement disclosure signal, and the timer or measurement stop signal is sent. Stop water level measurement.

上記の実施の形態の船舶の載荷重量算出システム１及び船舶の載荷重量算出方法によれば、従来技術の目盛り読み取り方式に比べて、電気信号処理できて目盛読み取り作業を不要にすることができて、計測対象の船舶３０と計測員Ａが乗っている小型船２０の間での水位計測の作業性を著しく向上することができ、しかも、人手を介して載荷重量を算出していたものを、予め、計測対象の船舶３０の載荷重量算出用データを算用データ入力部４１に入力しておくことで、水位データを自動的に取り込み、予め設定されたプログラムによって瞬時に喫水データとこの喫水データに基づいて載荷重量を算出することができる。そのため、載荷重量算出作業が軽減され、喫水計測作業を含む載荷重量確定作業を効率的に実施できる。   According to the loaded load amount calculation system 1 and the loaded load amount calculation method of the ship according to the above-described embodiment, compared with the conventional scale reading method, electrical signal processing can be performed and the scale reading work can be made unnecessary. In addition, it is possible to remarkably improve the workability of water level measurement between the ship 30 to be measured and the small ship 20 on which the measurer A is riding, and in addition, the load amount calculated through the manual operation, The load level calculation data of the ship 30 to be measured is input to the calculation data input unit 41 in advance, so that the water level data is automatically taken in, and the draft data and the draft data are instantaneously set by a preset program. The load amount can be calculated based on the above. Therefore, the load amount calculation work is reduced, and the load amount determination work including the draft measurement work can be performed efficiently.

Therefore, it can be used for calculating the load amount of the ship by draft measurement.
