Description
Technical field
Merged the present invention relates to one kind based on image and laser sensor, to determine unmanned boat refueling device specific location,
Unmanned refueling operation is realized, so as to improve the cruising ability of unmanned surface vehicle.Belong to unmanned boat applied technical field.
Background technology
As China greatly develops ocean strength, diversified ocean intelligence application and give birth to.Wherein nobody
Ship is as a kind of modernization intelligence for integrating the functions such as seafari, water quality detection, patrol on the sea and marine unmanned battle
System, is also developed rapidly.Since unmanned boat at this stage belongs to mini-plant in volume and tonnage, particularly exist
During the so vast region operation in ocean, its cruising ability is just particularly important, and directly decides the completion of a task
Whether.
In most cases, unmanned boat it is outgoing it is on duty during when low on fuel, then can need to return away from female ship
Base carries out refueling operation, this can undoubtedly limit its working range, its long-time and remote operation are caused to hinder.
In order to improve the cruising ability of unmanned boat, the present invention wants to carry fuel oil by using unmanned fuel feeding aircraft, arrives at unmanned boat institute
Fuel oil supplement is carried out to it in marine site.This can improve the intelligent level of unmanned boat, while decrease the throwing of manpower and materials
Enter, better guarantee be able to must be provided for the tasks carrying of unmanned boat.
The content of the invention
The object of the present invention is to provide a kind of autonomous fuel loading system of the unmanned boat based on image and laser sensor, solves nothing
People's ship adds the cruising ability of unmanned boat must make a return voyage because of Low oil Fuel during on duty the problem of, improve its from
Mainization degree.
The technical solution adopted by the present invention to solve the technical problems is：
A kind of autonomous fuel loading system of unmanned boat based on image and laser sensor, including unmanned boat 2 and unmanned fuel feeding aircraft
6, it is characterised in that：1）Equipped with green on boat-carrying GPS navigation 1, oiling shutdown cylindrical boss 14 and boss on the unmanned boat 2
Color triangle mark 15, fuel tank 7, be equipped with low oil mass alarm 3 in lower sidewall；2）It is equipped with the unmanned fuel feeding aircraft 6

Fuel tank 7 is connected with oil storage tank 4；4）On unmanned boat 2 and unmanned fuel feeding aircraft 6, a control cabinet 2-1 and control are carried respectively
Case 6-1 processed.The angle value and distance value that control cabinet 6-1 is sent according to laser radar 11 and camera 12 fly to control
The angle of inclination of 6 rotor of device and flying speed, when aircraft 6, which drops to oiling, shuts down above cylindrical boss 14, stop machine
The wing rotates, while controls elastic oiling pipeline 5 to stretch into 2 oil filler of unmanned boat.After the landing of aircraft 6, control adds control cabinet 2-1
Hydraulic fluid port automatically opens up, while makes the position of the fixation aircraft of fixed clamping device 13.
Be equipped with GPS navigation system on unmanned boat and unmanned fuel feeding aircraft, can obtain in real time unmanned boat and
The positional information of aircraft.When the situation of amount of fuel deficiency is occurring in unmanned boat during navigation, unmanned boat can stop navigating by water,
And female ship staff is given to send request of refueling by the low oil quantity alarming equipment on ship.Staff returns according to unmanned boat
GPS information, sets out unmanned fuel feeding aircraft and reaches specified waters.At this time, it is loaded in carry-on environmental perception module（Laser
And camera）Specific level point is judged into line search, judges that unmanned boat distance substantially and angle are believed by laser radar
Breath, judges specific level point, and slower speeds drop to nothing by camera after approaching according to the landing pattern on boat deck
People's ship is specified on deck.Then clamping is fixed to the position of fuel feeding aircraft by the fixed clamping device on ship, it is possible to
Allow oiling ejection pipeline to connect the oil inlet on the oil transportation mouth and unmanned boat of aircraft, realize the fuel oil supply to unmanned boat.
The present invention compared with prior art, have following obvious prominent substantive distinguishing features and notable technology into
Step：Cumbersome hand oiling operation has been abandoned, and then has used entirely autonomous oiling mode, has improved the continuation of the journey energy of unmanned boat
Power；For the mode independently refueled while manpower and materials input is reduced, refueling process is also simple operable；Using aircraft to nothing
The mode that people's ship refuels also improves oiling efficiency, compared to ship to the mode speed of ship faster, operability is stronger；System is whole
The entirely autonomous completion of refueling process, without human intervention, can further improve independence and the intelligence of unmanned boat.
