S1: The ultrasonic device 6 is used to sense whether there are fish passing by the feeding device. When the fish passing by, the camera device 4 starts to work to photograph the fish, and the data processing device performs image recognition on the captured fish to determine the fish Type, size and quantity to determine the type and quantity of materials needed;

The ultrasonic device 6 judges whether there are fish passing by in the current area. If there is no fish passing by, the camera device 4 sleeps. When there is a fish passing by, the camera device 4 starts to work, which can save more power. There are multiple ultrasonic transmitters, and they are evenly distributed in the central feeding On the outer wall of the cylinder 2, ultrasonic waves are emitted to the surroundings at the same time when working. When a school of fish passes nearby, the ultrasonic wave is reflected by the fish. When the reflected ultrasonic wave is received, the data processing device analyzes and processes the signal according to The direction and time of the reflected ultrasonic waves are used to determine the direction and distance of the fish school. At the same time, the camera device 4 starts to work.

The image analysis and processing process includes:

A: Compare the images with the pictures saved in the storage device to determine the species of the fish school, and select the feed species corresponding to the fish school;

B: Estimate the average size of the fish in the school according to the individual size of the fish in the image, and judge the overall stage of the fish in the school through the estimated average size of the fish. The overall stage is divided into the seedling stage, the growth stage, and the mature stage;

C: Estimate the number of fish in the school based on the density of the fish in the image, the estimated average size of the fish, and the size of the school of fish, and calculate the total number of fish based on the estimated number of fish and the amount of fish in each stage. The total amount of feed required;

S2: After determining the type and quantity of fish feed to be put in by S1, monitor the remaining condition of the type of fish feed in the corresponding storage tank 5 through the residual feed monitoring device. When the fish feed is insufficient or the feed is finished, the feeding device passes The wireless communication device sends a replenishment signal to the cloud management center;

By setting the gravity sensor 15 under the push plate 13, the total weight of the push plate 13 and the remaining fish material can be measured. The weight of the push plate 13 is a fixed value, so the total weight obtained by the gravity sensor 15 is calculated by the data processing device. Subtracting the weight of the push plate 13 is the weight of the remaining fish material;

The feed signal includes the type of fish feed that needs to be replenished, the coordinate position of the feeder that needs to replenish the fish feed, and the cloud management center sends the feed signal to the nearest waiting job after the integrated analysis of the feeder signal The feeding drone in the state enables the feeding machine that needs to be fed to communicate directly with the drone. The feeding drone plans a navigation route according to the coordinate position of the feeding machine, and flies to the top of the feeding machine. After the drone reaches the command position, it sends the arrived signal to the feeder. The infrared transmitter 22 on the feeder emits infrared rays upwards. At the same time, the central feeding cylinder 2 starts to rotate under the driving of the rotating device. When the receiving device 28 receives the infrared signal, it sends an aligned signal to the feeder. The feeder stops rotating after receiving the aligned signal, and then the upper end cover of the storage box 5 on the feeder that needs to be supplemented with fish material Driven by the motor to open, after the box cover 16 is opened, the electric valve 27 below the storage box 26 corresponding to the storage box 5 on the replenishing drone is opened, so that the fish material can fall into the feeding of the storage box 5 below In the hopper 21, the fish material can slide into the storage box 5 from the side wall of the feeding hopper 21;

When refilling, the push plate 13 should move down to the initial position. With the replenishment of the fish material, the weight monitored by the weight sensor 15 becomes larger and larger, and when it reaches the rated value of the fish material that the storage box 5 can store At the time, the feeder sends a signal of completion of the feeding to the feeding drone. After receiving the signal, the feeding drone closes the electric valve 27 at the bottom of the feeding box 26 so that the fish will no longer fall and close the electric valve 27 After that, the replenishing drone returns according to the navigation route. At the same time, the lid 16 at the upper end of the storage box 5 is closed. The steering motor 18 can drive the central feeding barrel 2 to rotate through the cooperation of the driving gear 19 and the gear ring 20 to turn the blowing hopper 17 The opening faces the direction of turning the fish school, and the push plate 13 is slowly moved upward by the cylinder 14 in the storage box 5 to push the fish material upward. When the height of the fish material exceeds the height of the feeding end of the feeding pipe 12, the fish The material particles can slide down from the feeding pipe 12 into the central feeding cavity 7, and slide down the inner wall of the central feeding cavity 7 into the blowing cavity 8. The blowing machine 3 blows the fish feed falling into the blowing cavity 8 to the lake surface, When the reduction of the fish material in the storage tank 5 reaches the weight of the fish material that needs to be put in, stop feeding;

S5: The same fish school is fed only once within 24 hours. It can be judged whether it is the same fish school by the type, size and quantity of the fish school. After each feeding, the type and Data such as size and quantity are stored in the storage device. When the school of fish passes the feeding device multiple times within 24 hours, it is convenient for the data processing device to determine whether the school of fish has been fed.

Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, and substitutions can be made to these embodiments without departing from the principle and spirit of the present invention. And variations, the scope of the present invention is defined by the appended claims and their equivalents.
