Description

A kind of hull bottom intelligence underwater cleaning robot, control system and control method
Technical field
The invention belongs to technical field of robot control more particularly to a kind of hull bottom intelligence underwater cleaning robots, control System and control method.
Background technique
Currently, underwater be widely used in pipe inspection, hull maintenance, research and teaching, underwater amusement, underwater archaeology, The how civilian and military domains such as fishery, ocean bottom cable inspection.
As exploration range of the people to ocean is more and more wider, the demand to ocean development is more and more stronger, hull bottom intelligent water Lower cleaning robot becomes the object of whole world research.
Hull bottom intelligence underwater cleaning robot be by artificial intelligence, automatic control, pattern-recognition, information fusion with understand, The technologies such as the system integration are applied on traditional carrier, and preplanned mission in complicated marine environment is completed in the case where unmanned Robot.
Currently, with the extensive use in computer technology alow intelligent underwater cleaning robot, people will be using more New technique, the control hull bottom intelligence underwater cleaning robot more visualized.
In the prior art, underwater robot is only limitted to synthetic aperture sonar, forward sight for undersea detection and the equipment of identification The underwater sound equipments such as sonar and three-dimensional imaging sonar.Being not bound with intelligent control technology is the independence for improving underwater robot, is made It cannot be completed various tasks in complicated marine environment.
Synthetic aperture sonar is to move along space linear uniform motion come virtual large aperture basic matrix using small size basic matrix The ordinal position transmitting of track and receives echo-signal, according to spatial position and phase relation to the echo-signal of different location into The processing of row coherent superposition, to form equivalent large aperture, acquisition is very suitable to along the high resolution of the direction of motion (orientation) The little underwater robot of scale, can be used for scouting, detect, high-resolution imaging, be underwater in the survey of large-scale terrain landforms etc. Robot provides a kind of good detection means of performance.
The image acquisition and processing system of Forward-looking Sonar independently acquires and identifies under water target under computer network management Image information realizes the tracking to target and the guidance to underwater robot.Wave beam used by underwater sound wave is narrower, and frequency is got over Height, the then image formed are more clear.By the real-time accurately display submarine target of the aobvious control of sonar apart from information such as orientation, to scheme The form of picture in time efficiently shows sub-marine situations on the screen, understanding submarine target and environment that can be clear and accurate, with Accurately judgement and reply are made, detection or navigation are completed.
Three-dimensional imaging sonar of the three-dimensional imaging sonar for the identification of submarine target, be-one total digitalization, it is programmable, The modular system with flexibility and easily modified.The shape information that submarine target can be obtained, provides for Underwater Targets Recognition Advantageous tool.
In conclusion problem of the existing technology is:
(1) in the prior art, underwater robot is only limitted to synthetic aperture sonar, preceding for the equipment of undersea detection and identification Depending on the underwater sound equipments such as sonar and three-dimensional imaging sonar, being not bound with intelligent control technology is the independence for improving underwater robot, It causes to complete various tasks in complicated marine environment.
(2) most important in mechanical aspects is exactly seepage problem, and electronics storehouse is the device that is sealed for having end cap, but due to envelope Secret skill art is immature, and little water how much can be penetrated into storehouse and is entered.
Solve the difficulty and meaning of above-mentioned technical problem:
Since the environment of underwater robot operation is complicated, the noise of underwater sound signal is big, and wave beam is unstable or the various underwater sounds The disadvantage that the generally existing precision of sensor is poor, jump is frequent, therefore in AUV Control system, filtering technique is aobvious It obtains particularly important.
In order to improve the leakproofness of warehouse, electronics Hatch Opening is added one layer of rubber ring by the present invention, when sealing with sealing cover inside groove Tightly touch.For effect, we will be sealed the lengthening of lid inside groove, and add several layers of rubber rings in inside groove periphery, inside groove when sealing The rubber ring of periphery tightly touch electronics storehouse inner wall.To reach good waterproof effect.
