Description

本考案は、レーダーの見張警報機能を利用したヒューマンエラーによる海難事故(衝突および乗揚げ事故)を防止するための船舶の操船者支援装置に関するものである。 TECHNICAL FIELD The present invention relates to a vessel operator assistance device for preventing maritime accidents (collisions and grounding accidents) caused by human error using a lookout warning function of a radar.

漁船、プレジヤーボートなどの小型船だけでなく貨物船やタンカーなどの大型船も長年海難事故が多発し続け多くの人命や財産が失われている。
これは操船者のヒューマンエラーに起因する居眠り、見張り不十分が主たる原因である。
Over the years, not only small vessels such as fishing boats and pleasure boats, but also large vessels such as cargo ships and tankers have been involved in numerous maritime accidents, resulting in the loss of many lives and property.
This is mainly caused by dozing off and inadequate lookout due to human error of the operator.

漁船、プレジャーボートなどの小型船では小型ながらも高性能のレーダーが設置され、一方大型船舶では法律によってARPAレーダー(自動衝突予防援助装置)、AIS(船舶自動識別装置)、BNWAS(船橋航海当直警報装置)の設置が義務付けられている、ところがこれらの装置を取り扱うのは生身の人間であるためにヒューマンエラーという問題は切りはなせないので船の大小にかかわらず海難事故が絶えない。
ヒューマンエラーによる海難事故の大半の衝突、乗揚げ事故の原因は好天、海上平穏、夜間より昼間等、視界良好な条件の時に最も多く発生しており、その原因が操船者の居眠り、うっかりミス等であり、その反対の条件の場合には操船者は神経を集中し操船するために事故はむしろ少ないのである。
Small ships such as fishing boats and pleasure boats are equipped with small but high-performance radars, while large ships are legally equipped with ARPA radar (Automatic Collision Prevention Assistance System), AIS (Automatic Identification System), and BNWAS (Bridge Navigational Watch Alarm). However, because these devices are handled by human beings, the problem of human error cannot be ruled out.
The majority of maritime accidents caused by human error, such as collisions and grounding accidents, occur most frequently under conditions of good visibility, such as good weather, calm sea conditions, and daytime rather than nighttime. etc., and in the opposite case, accidents are rather rare because the operator concentrates on maneuvering.

舶用レーダーにはすべて「見張り警報機能」が備えられており自船を中心に円周上に見張り警報範囲を設定し、この範囲に他船、浮標や岩礁などの対象物が入った場合レーダーの外部警報ブザーを鳴らす構造になっている。
ブザーが鳴った場合その音に気がついて注意し適切な操船をすれば海難事故は起こらないのであるが、操船者が居眠りや見張り不十分など漫然とした操船の結果事故を起こしているのが大半である。
また警報範囲を広く設定していた場合その範囲に、多くの対象物が検知されブザーがなりっぱなしになって「うるさい」といって電源を切ってしまう場合が多い。
事故というのはいつ何時起こるかもしれない必要な時にその役割を果たさないのでは意味のないことである。
そこで本案では外部ブザーに送られてくる警報信号を検出すると警報コントローラー内に設けられたタイマーが働き警報信号の継続時間をカウントする。
継続時間の長さすなわち衝突、乗揚げ事故の危険性が増すにつれて段階的に警報ランプを点滅させるとともに、警報信号(メロデイ、外部ブザー、汽笛、火災警報器、モーターサイレンなど)を発信し、操船者だけでなく他の乗船者また接近してきた他船に対しても警報を鳴らすことによってヒューマンエラーによる海難事故を防止するための操船者支援装置である。
海難事故は船が輻輳する港近くで発生するよりもむしろ何もない広大な海で発生することが多く、また自動操舵で航行している時に発生するため常にレーダーによる見張りは欠かせない。
特に漁船においては過酷な夜の漁によって疲労していながら早朝の市場に間に合うように、自動操舵によって船を走らせたあげくつい居眠りをしてしまって事故を起こすケースが多発している。
All marine radars are equipped with a "lookout warning function". A lookout warning range is set on the circumference of your ship. It is structured to sound an external alarm buzzer.
When the buzzer sounds, if you pay attention to the sound and operate the ship appropriately, no marine accidents will occur. be.
In addition, when a wide alarm range is set, many objects are detected in that range, and the buzzer keeps sounding.
Accidents are meaningless if they do not fulfill their role when necessary, which may occur at any time.
Therefore, in the present invention, when an alarm signal sent to an external buzzer is detected, a timer provided in the alarm controller is activated to count the duration of the alarm signal.
As the duration increases, i.e., the risk of a collision or run-over accident increases, the warning lamp flashes in stages, and warning signals (melody, external buzzer, whistle, fire alarm, motor siren, etc.) are sent to steer the ship. It is a ship operator support device for preventing marine accidents caused by human error by sounding an alarm not only to the occupants but also to other passengers and other ships approaching.
Maritime accidents often occur in vast open seas rather than near congested ports, and since they occur when sailing on autopilot, a constant radar lookout is essential.
Especially in fishing boats, there are many cases of accidents caused by falling asleep after running the boat by automatic steering in time for the early morning market while being tired from harsh night fishing.

上述のようにブザーが鳴り続け「うるさい」とスイッチを切ってしまわれないように、本案では見張り警報の範囲に対象物が進入するとまずメロデイを鳴らし、操船者がブザー音で苛立つこともなくスイッチを切らずに、見張り警報の範囲に障害物が入っていることを認識することが出来る。
軽快なメロデイーによって余計居眠りが深くなったとしても次にあらかじめ設定された時間(T1秒)に達すると警報(ブザー、火災警報器)を発し、ヒューマンエラーの状態になっていた操船者に注意を促し、衝突、乗揚げ事故を回避することが出来る。
また最後の手段としてあらかじめ設定された時間(T2秒)に達するとブザー、火災報知機、汽笛、警告灯など全ての警報信号を発し、自船の他の乗組員に知らせるとともに、接近してきた他船にも危険を知らせ事故を未然に防止することができる。
本案はこのようにレーダーを見張り警報機能をセンサーとして利用し、レーダーの持つ高性能を保ちながら使い勝手がよく安価で普及しやすい見張り警報装置を提供するものである。
In order to prevent the buzzer from sounding continuously as described above and turning off the switch, in this proposal, when an object enters the range of the lookout alarm, a melody will sound first, and the operator will switch without being irritated by the buzzer sound. It is possible to recognize that an obstacle is in the range of the lookout alarm without turning off the watch.
Even if the light melody causes the ship to fall asleep excessively, the alarm (buzzer, fire alarm) will be issued when the next preset time (T1 second) is reached, alerting the operator who was in a state of human error. It is possible to avoid collisions and run-on accidents.
Also, as a last resort, when the preset time (T2 seconds) is reached, all alarm signals such as buzzers, fire alarms, whistle, and warning lights are emitted to notify other crew members of the ship, and others approaching. It is possible to inform the ship of danger and prevent accidents.
In this way, the present proposal utilizes the watch-alarm function of the radar as a sensor to provide a watch-and-alarm device that maintains the high performance of the radar, is easy to use, and is inexpensive and easy to spread.

An embodiment will be described below with reference to FIG.
A shows the state in which a circular 7 lookout warning range is set around the own ship on the radar screen. , the alarm controller lamp is green light is on.
B indicates that 8 other ships have entered the lookout warning range.
An alarm signal is emitted from an external buzzer and a timer (not shown) within the alarm controller begins to measure elapsed time.
At the same time, a melody plays to inform the operator of the warning signal.
Unlike the buzzer, the operator can calmly observe the sea conditions without turning off the switch without being irritated by the buzzer, and can continue the voyage by properly maneuvering the vessel.At this time, the yellow lamp lights up. there is
In C 8, when the other ship continues to approach and the timer counts T1, the orange light of the alarm controller lights up, and at the same time the alarm buzzer and fire alarm sound, even if the operator is in a state of human error. An accident can be prevented by normal ship maneuvering, awakened by a loud warning sound.
D8 When other ships are getting closer and the risk of collision increases and the timer counts T2, the red light on the alarm controller will start flashing and all other lights will flash at the same time.
At the same time, an alarm (buzzer, fire alarm, whistle, etc.) is activated to notify the other ship of the imminent danger of collision and encourage them to take evasive action.
E6 indicates that another ship approaches while the own ship is stopped.
In this case as well, a collision can be avoided by issuing an alarm signal in the same manner as in (B to D) above.
[Fig. 4] Explanation of time chart A When the lookout warning range is set with the radar and the power of the warning controller is turned on, the green light lights up and the ship can sail safely.
B When an obstacle is detected within the lookout warning range, the yellow light on the warning controller lights up, a melody plays, and the timer starts running.
When the C timer passes T1 (seconds), the orange light will turn on, and the buzzer and fire alarm will sound.
When the D timer passes T2 (seconds), the red light begins to flash, and at the same time other lamps flash, and the buzzer, fire alarm, and whistle all alarm.
Flashing lamps and alarms will continue to ring unless the switch is turned off.
