Step 10, judge, if there are no obstacles in the direction of Ai navigation, go to step 11, if there are obstacles, go to step 14;

Step 11: Collect the sensor information, and the unmanned boat Ai obtains the dissolved oxygen, COD, PH, and turbidity sensor information in the form of 485 bus through U3, and proceeds to step 12 after completion;

Step 12, judge, if the collected sensor data is normal, go to step 13, if abnormal, go to step 16;

Step 13. Collect video information, and the unmanned boat Ai obtains video information of the navigation area through the U9 camera module, and returns to step 2 after completion;

Step 14: An alarm is issued, and the unmanned boat Ai sends the information of finding obstacles to the integrated control platform through the link Ai12. At this time, the Z1, Z2, Z3, Z4 and Z8 areas of the integrated control platform are automatically switched to target unmanned. The control interface of the boat Ai, after the completion, proceed to step 15;

Step 15: Obstacle avoidance algorithm. The unmanned boat Ai runs the obstacle avoidance algorithm according to the distance and azimuth information of the surrounding obstacles to obtain a new navigation mission. After completion, it proceeds to step 6;

Step 16. An alarm is issued, and the unmanned boat Ai sends the sensor data exceeding the threshold value through the link Ai12 to the integrated control platform. At this time, the Z1, Z2, Z3, Z4 and Z8 areas of the integrated control platform are automatically switched to For the control interface of the unmanned boat Ai, go to step 17 after completion;

Step 17: The optimization strategy of the detection task. The unmanned boat Ai runs the optimization strategy of the detection task based on the abnormal sensor data to determine the location of the water area that needs to be monitored. After completion, it proceeds to step 6.
The application in the unmanned boat cooperative detection and control program according to claim 9, characterized in that, in step 7, the data content includes the position, heading of the unmanned boat Ai, the current sailing mission, and video information And sensor data.
