Abstract
The invention relates to a method and a system for cleaning a water area by cooperation of an unmanned aerial vehicle and an unmanned ship.
Description
Technical Field
The invention relates to the technical field of water area cleaning, in particular to a water area cleaning method and system with cooperation of an unmanned aerial vehicle and an unmanned ship.
Background
In recent years, with the continuous progress and maturity of intelligent device technology, it becomes feasible to perform repeated and heavy work with unmanned devices to assist people even instead of people. Especially for the task on water, use unmanned equipment to replace artifical, can be fine avoid the staff to face the dangerous condition because of the unstability of water condition, when liberating the manpower, guaranteed people's safety.
The unmanned ship has great advantages in the aspect of performing overwater operation, particularly performing a water area garbage cleaning task. For example, an unmanned ship for cleaning developed by eastern water conservancy companies can be used for fishing solid garbage such as water surface floaters of oceans, lakes and ponds. The ship is provided with an intelligent monitoring device on the ship body for identifying a planned path; in addition, two fan wheels are arranged in front of the ship body to collect the garbage in the fixed area in front of the ship body to the chain wheel net, and the garbage is rolled into the cabin through the chain wheel net. On one hand, the application of the unmanned ship frees a large amount of manpower and ensures the personal safety of people to a great extent; on the other hand, when the unmanned ship executes a cleaning task, due to limited visual field, the whole water area is often required to be fully covered to determine the position of the garbage, that is, at least one complete traversal is required. For the situation that the area of the water area is large or the garbage distribution area is relatively concentrated, the ship traverses the whole water area, undoubtedly, large time cost is generated, and meanwhile, resources are wasted.
The unmanned aerial vehicle is used for directly picking up the suspended garbage on the water surface to clean the water area. The unmanned aerial vehicle has a larger global view advantage, and the area of the area which can be covered in unit time is far larger than that of the unmanned ship; but because ordinary unmanned aerial vehicle is general nimble small and exquisite, often single flight can only pick up a target object and time of endurance is short, if carry out the clearance task alone, then need return many times and fix the suspended solid of taking off and land and placing the pick-up or change the battery, can make unmanned aerial vehicle battery energy mostly be consumeed on the way that comes and goes of rubbish and take off and land point, can cause the very big waste of resource equally.
By last, unmanned aerial vehicle respectively has its advantage with unmanned ship when carrying out the waters clearance task, has consequently appeared the third kind clearance scheme: unmanned aerial vehicle unmanned ship clearance in coordination. According to the scheme, the unmanned aerial vehicle is used for executing a covering task, and water surface images are collected and transmitted back to the unmanned ship; the unmanned ship analyzes the image to determine the area where the garbage is located, generates an optimal path leading to each garbage node, and executes a cleaning task. Although the scheme improves the cleaning efficiency to a certain extent, certain defects exist. Firstly, in the process of executing a coverage task by the unmanned aerial vehicle, the unmanned aerial vehicle is always in a waiting state; when the unmanned ship executes a cleaning task, the unmanned ship also needs to wait for the unmanned ship to complete the task due to the communication distance and the electric quantity of the unmanned ship; secondly, the single flight distance of the present civil unmanned aerial vehicle is about 10 kilometers, and if the unmanned aerial vehicle fixed-point take-off and landing scheme is adopted, the unmanned ship still needs to be frequently returned so as to replace the battery. The above two points make the unmanned aerial vehicle unmanned ship not have high cooperative efficiency.

S20, synchronizing the garbage distribution information of the sub-area to all unmanned ships, and then sending cleaning tasks of the target sub-area to the unmanned ships which are closest to the target sub-area and have no cleaning tasks;
it should be noted that, in this embodiment, the unmanned ship has a plurality of unmanned ships dispersed in the target cleaning water area, and each sub-area generally has only one unmanned ship, and when there is an unmanned ship executing a cleaning task, the remaining unmanned ships need to pass through the sub-area executing the cleaning task, so as to avoid interfering with the cleaning task of the unmanned ship.
S30, after the unmanned aerial vehicle traverses all the sub-areas, the unmanned aerial vehicle is controlled to land to a distance from the unmanned ship nearest to the unmanned aerial vehicle, and after all the sub-area cleaning tasks are completed, all the unmanned ships are controlled to go to a preset place, and the cleaning of the water area is completed.
It is worth emphasizing that the unmanned aerial vehicle has weak cruising ability, so that the unmanned aerial vehicle can take off and land on the unmanned aerial vehicle, the flight range of the unmanned aerial vehicle is expanded, and the efficiency of acquiring water surface images by the unmanned aerial vehicle is improved.
The embodiment divides the target cleaning water area into a plurality of sub-areas, and utilizes an unmanned aerial vehicle and a plurality of unmanned ships to respectively carry out image information acquisition and garbage cleaning on the plurality of sub-areas, thereby greatly reducing the waiting time of the unmanned ships and unmanned aerial vehicles for waiting for the other side to complete tasks, solving the technical problem of low cooperative efficiency of unmanned aerial vehicles and unmanned ships in the prior art, and achieving the effect of improving the water area cleaning speed of the unmanned aerial vehicles and unmanned ships under cooperation.

S13, controlling the unmanned aerial vehicle to traverse the next target area after the unmanned aerial vehicle completes traversing;
it is worth emphasizing that, in this embodiment, unmanned aerial vehicle need not to wait for unmanned ship to clean after traversing, can directly carry out the traversal work of next target area, greatly reduced unmanned aerial vehicle's latency, improved synergistic efficiency.
And S14, controlling the unmanned ship to analyze all the traversed water surface images to generate garbage distribution information.
It is easy to understand that the picture processing function is arranged on the unmanned ship, so that all collected water surface images are spliced by the unmanned ship, and garbage in the images is identified and positioned, thereby facilitating subsequent garbage cleaning work.
Specifically, after the unmanned aerial vehicle traverses the target area, the step of controlling the unmanned aerial vehicle to traverse the next target area further includes:
after the unmanned aerial vehicle finishes traversing, the unmanned aerial vehicle sends a request for obtaining the distance of the nearest unmanned ship;
it should be noted that, because the cruising ability of the unmanned aerial vehicle is weak, in order to avoid the situation that the unmanned aerial vehicle needs to traverse again after half of the power failure and the battery is replaced, and time is wasted, it is necessary to estimate whether the unmanned aerial vehicle can complete the work of the next stage after the traversal is completed.
And the unmanned aerial vehicle executes the action of returning to the nearest unmanned ship to replace a battery or traversing the next target sub-region according to the received distance information between the unmanned aerial vehicle and the nearest unmanned ship, the self electric quantity and the power consumption for traversing the target sub-region.
The unmanned aerial vehicle is characterized in that when the electric quantity of the unmanned aerial vehicle is not enough to traverse the next target area and return to the nearest unmanned ship to replace the battery, the unmanned aerial vehicle directly goes to the nearest unmanned ship to replace the battery, and if the electric quantity of the battery is enough to traverse the next target area and return to the nearest unmanned ship to replace the battery, the unmanned aerial vehicle executes the action of traversing the next target sub-area.
Specifically, the step of dividing the target cleaning water area into regular sub-areas of a preset size further includes:
planning a traversal sequence of the unmanned aerial vehicle according to the divided target cleaning water area shape and numbering all the subareas;
it is easily understood that, in order to improve traversal efficiency, reduce unmanned aerial vehicle's invalid flight, this embodiment reaches this purpose through planning the traversal order in advance, simultaneously, through numbering the subregion, is convenient for to unmanned aerial vehicle and unmanned ship appointed target subregion be which region, is convenient for artifical later stage simultaneously and is analyzed and review this rubbish cleaning work.
And taking the sub-region with the smallest number and not traversed as a target sub-region, and taking the sub-region with the second smallest number and not traversed as a next target sub-region.
It should be noted that, in this embodiment, the target sub-area and the next target sub-area are defined, so that the technical scheme is improved, the unmanned aerial vehicle and the unmanned ship can continue the previous traversal work according to the previous traversal condition, repetitive labor is avoided, and the garbage disposal efficiency is improved.

Referring to fig. 4, after synchronizing the sub-area garbage distribution information to all unmanned ships, the step of issuing a cleaning task of a target sub-area to the unmanned ship which is closest to the target sub-area and has no cleaning task further includes:
s21, generating a cleaning path of the unmanned ship by adopting a shortest path algorithm according to the garbage distribution information and the unmanned ship position information for executing the cleaning task;
it is easy to understand that, in the technical scheme of the embodiment, the path is reasonably planned through the shortest path algorithm, so that the time for cleaning the known garbage in the unmanned ship cleaning area is reduced, the garbage cleaning speed is increased, and the energy consumption is reduced.
And S22, controlling the unmanned ship to clean the target sub-area according to the cleaning path.
Specifically, as shown in fig. 5, the unmanned ship is controlled to clean the target sub-area according to the cleaning path. After the step (2), further comprising:
and S23, after the cleaning task is completed, controlling the unmanned ship to move forward and next to be cleaned and no subarea of the unmanned ship exists.
It should be noted that, this embodiment is through carrying out arrangement in advance to the unmanned ship that the clearance was accomplished for unmanned aerial vehicle has traversed the subregion after, and unmanned ship can be faster drop into the rubbish clearance work and go, has reduced the required time of rubbish clearance, has promoted rubbish clearance efficiency.

According to the technical scheme, the unmanned aerial vehicle and unmanned ship cooperative water area cleaning method further comprises the following steps:
after the unmanned aerial vehicle traverses the target sub-area, acquiring position information of all unmanned ships;
it is easily understood that, because unmanned aerial vehicle and unmanned ship have certain communication range, and unmanned aerial vehicle need send the surface of water image to unmanned ship, consequently, need ensure that unmanned aerial vehicle is in unmanned ship's communication range all the time, so need acquire the positional information of whole unmanned ship.
Taking a preset communication distance as the communication radius of the unmanned ship, and judging whether the traversal path of the unmanned aerial vehicle is at least positioned in the communication radius of one unmanned ship or not according to the position information of all the unmanned ships;
it should be noted that the situation of effective coverage of the communication signal can be obtained only by drawing a circle with a radius as the communication radius with the positions of all unmanned ships as the origin, and at this time, whether all the traversal paths of the unmanned aerial vehicle are located in the effective coverage range can be judged.
And when the unmanned aerial vehicle is not positioned in the communication radius of one unmanned aerial vehicle, adjusting the navigation route of the unmanned aerial vehicle which is not executing the cleaning task, so that the traversal path of the unmanned aerial vehicle is positioned in at least one communication radius of the unmanned aerial vehicle.
It is worth emphasizing that since the unmanned ship executing the cleaning task has a preset navigation route, only the unmanned ship not executing the cleaning task can be adjusted, and in general, coverage of the unmanned aerial vehicle traversal path can be realized only by arranging one unmanned ship in the middle range of the sub-area.
