Abstract

The invention relates to the technical field of maritime searches and rescue and surveys, in particular to an automatic collision preventing control method of a USV, and aims at providing the automatic collision preventing control method of the USV. By means of mutual cooperation among all subsystems of a whole collision preventing system, the unmanned surface vehicle (USV) can automatically search for obstacles and implement collision preventing strategies according to distribution of the obstacles when the USV executes tasks such as rescue and surveys. The method comprises the following steps that 1, environmental image information is collected; 2, the distance between the obstacles and the USV is measured; 3, a GPS measures relative position information of the USV with other USVs, and a tachometer measures the movement velocity of the USV and other USVs; 4, an obstacle judgment system processes received information; 5, the sea clutter situation is transmitted to a genetic algorithm controller; 6, the genetic algorithm controller generates the collision preventing strategies. The automatic collision preventing control method of the USV is suitable for the technical field of the maritime searches and rescue and surveys.

Example Embodiment

[0023] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 1. The method for autonomous collision avoidance control of a USV described in this embodiment is carried out according to the following steps:
[0024] 1. The camera will capture environmental images within a 360° range centered on the unmanned boat, and transmit the image information to the image recognition system;
[0025] 2. The image recognition system processes the image information and transmits the suspected obstacle information to the obstacle judgment system. At the same time, the range finder measures the distance between the obstacles within 500 meters of the unmanned boat and the unmanned boat, and transmits the information to the unmanned boat. Obstacle judgment system;
[0026] 3. The GPS positioning system locates the current position of the unmanned boat in real time, the communication system establishes contact with other unmanned boats, and obtains the relative position information of the own boat and other unmanned boats, and the speedometer measures the unmanned boat and other unmanned boats. The speed of movement of other unmanned ships is equivalent to an obstacle, and then the above information is transmitted to the obstacle judgment system;
[0027] 4. The obstacle judgment system processes all the received information and transmits the obstacle data to the genetic algorithm controller;
[0028] 5. The wind, wave and current monitoring system monitors the sea surface disturbance in the sea area where the unmanned boat is located in real time, and transmits the data to the genetic algorithm controller;
[0029] 6. The genetic algorithm controller formulates a collision avoidance strategy according to the obstacle data and performs safe collision avoidance through the actuator.
[0030] This embodiment includes the following beneficial effects:
[0031] 1. In this embodiment, through the cooperation and cooperation between the subsystems of the entire collision avoidance system, the unmanned boat can autonomously search for obstacles when performing tasks such as search and rescue, survey, etc., and implement collision avoidance strategies according to the distribution of obstacles to ensure The safety of unmanned boats during autonomous navigation;
[0032] 2. This embodiment reasonably combines the collision avoidance subsystems of the unmanned boat, and completes the unmanned boat from searching the nearby navigation environment, collecting and analyzing obstacle information, formulating collision avoidance countermeasures, and completing the obstacle avoidance. A series of processes have effectively improved the intelligence of the unmanned boat and reduced the workload of the operator;
[0033] 3. When the unmanned boat is performing tasks such as search and rescue, survey, etc., it can safely avoid collisions with static and dynamic obstacles in the process of traveling according to the method described in this embodiment.
