The detection instruction can be sent by the active control of a user, or can be sent by the unmanned ship. Specifically, the main controller of the unmanned ship sends a sonar opening/closing signal to control the opening/closing of the detection body of the detection device.
In an embodiment, the unmanned ship can receive an on/off instruction of the wireless control device to control the unmanned ship main controller to send a sonar on/off signal. Specifically, when the unmanned ship receives an opening instruction, the unmanned ship main controller sends a sonar opening signal; when the unmanned ship receives the closing instruction, the unmanned ship main controller sends a sonar closing signal.
In one case, main control unit sends sonar opening signal, and the detection main part of detection device is opened in control to the realization is to the detection of aquatic or the underwater condition. In another case, the unmanned ship main controller sends a sonar closing signal to control the closing of the detection body of the detection device to close the detection of the underwater or underwater situation.

And the rotating direction and the rotating angle are determined according to the detection command.
Specifically, when the detection instruction is environmental detection, for example, submarine topography detection, fish condition are surveyed, main control unit control driving motor rotates in order to drive the dead lever and make sonar detection face aim at corresponding position, as shown in fig. 3. At the moment, the detection command comprises a first rotating direction and a first rotating angle so as to control the output shaft of the driving motor to rotate the first rotating angle along the first rotating direction. The first rotation direction is a counterclockwise direction, and the first rotation angle is 0 ° to 90 °, for example, may be 10 °, 20 °, 30 °, 45 °, 50 °, 60 °, 70 °, 80 °, 90 °. When the detection instruction is for obstacle detection, the main controller can control the driving motor to rotate, so that the sonar detection surface faces the front or the upper part, and obstacles such as submerged reefs or aquatic weeds in the traveling direction of the unmanned ship are detected, as shown in fig. 4. The detection instruction may include a second rotation direction and a second rotation angle to control the output shaft of the driving motor to rotate by the second rotation angle along the second rotation direction.

The predetermined threshold is determined according to the type of the probing instruction.
Specifically, when the detection instruction is environment detection, the preset threshold value of the included angle theta between the central line of the second fixed rod and the central line of the first fixed rod is smaller than 90 degrees, so that the sonar detection surface can be maintained at a position capable of detecting underwater scenes under a ship, such as underwater topography, landscape or creatures. When the detection instruction is for detecting the obstacle, the preset threshold value of the included angle theta between the central line of the second fixed rod and the central line of the first fixed rod is larger than 90 degrees, so that the sonar detection surface faces the front or the direction of the travelling route to detect the obstacle in the water.
Step S603: sonar signals are received by the probe body.
Step S604: judging the type of a detected object corresponding to the sonar signal according to the detection instruction and the sonar signal;
step S605: and controlling the unmanned ship to execute corresponding operation according to the type of the detected object.
Specifically, in step S604 and step S605, when the detection command is the obstacle detection, it is determined whether or not the type of the object to be detected corresponding to the sonar signal is an obstacle. And when the type of the detected object is an obstacle, sending an adjusting instruction to adjust the moving track of the unmanned ship. Wherein the adjustment instruction includes direction and angle of adjustment, and the step of adjusting unmanned ship's movement track still includes: and adjusting the unmanned ship to the adjustment angle along the adjustment direction. The method comprises the steps of adjusting along the direction of an unmanned ship bow, adjusting along the direction of a ship stern and adjusting along the direction of a ship body. And further, the navigation track of the unmanned ship is changed to avoid the obstacle.

Therefore, the embodiment of the invention can enable the unmanned ship to avoid the detected obstacles when the unmanned ship runs.
When the detection instruction is environment detection, the type of the detected object corresponding to the sonar signal is judged to be a terrain or a fish school. When the detection instruction is environment detection, the main controller processes the received sonar signals and converts the sonar signals into sonar images, and the sonar images are transmitted to the display interface. The display interface can be a remote device which is in communication connection with the unmanned ship in a wireless or wired mode, and can also be arranged on the unmanned ship.
Therefore, by using the method provided by the embodiment of the invention, underwater obstacles such as submerged reefs, aquatic weeds and the like can be detected, and water obstacles can also be detected. When an obstacle is detected in the driving direction of the unmanned ship, the unmanned ship main controller sends an adjusting instruction to adjust the moving track of the unmanned ship, the unmanned ship main controller repeatedly judges whether a detection main body receives a sonar signal, and if the sonar signal is received, the adjusting instruction is sent to adjust the moving track of the unmanned ship until the sonar signal is not received. Therefore, the embodiment of the invention can enable the unmanned ship to avoid the detected obstacles when the unmanned ship runs.

Of course the adjustment angle can also be adjusted transversely of the stern or hull.
Therefore, by using the method provided by the embodiment of the invention, underwater obstacles such as submerged reefs, aquatic weeds and the like can be detected, and water obstacles can also be detected. When an obstacle is detected in the driving direction of the unmanned ship, the unmanned ship main controller sends an adjusting instruction to adjust the direction of the bow of the unmanned ship, the unmanned ship main controller repeatedly judges whether a detection main body receives a sonar signal or not, and if the sonar signal is received, the adjusting instruction is sent to adjust the direction of the bow of the unmanned ship until the sonar signal is not received.
