Description

Technical Field

[0001] The utility model relates to the technical field of pest trapping, in particular to a fruit fly trapping device. Background Art

[0002] Fruit fly pests belong to the order Diptera and the family Tephritidae, and are pests of important economic significance. They are distributed globally and mainly harm fruit and vegetable horticultural crops. Adult fruit flies lay eggs inside fruits and vegetables, and after the larvae hatch, they bore into the fruits and vegetables, causing the fruits to rot and fall off, seriously affecting the quality and yield of fruits, melons and vegetables. Once adult fruit flies lay eggs, irreparable losses will be caused. Therefore, trapping adult fruit flies is an important means to reduce economic losses.

[0003] CN206165568U discloses a mango fruit fly trap, which includes a bottle body. One or more insect inlet holes are provided on the side wall of the bottle body, and a sugar-vinegar trapping agent is arranged inside the bottle. The insect inlet holes are rectangular holes, and baffles connected to the side wall of the bottle body and extending obliquely into the bottle body are arranged on the left and right sides of the insect inlet holes. The application of this trap has the following two disadvantages: First, after fruit flies die, their corpses accumulate at the bottom of the bottle body, which will cause the fruit flies to block each other and also cover the sugar-vinegar trapping agent, weakening the trapping effect; Second, if the concentration of the sugar-vinegar trapping agent is too high or the number of uses is too many, it will cause the growth of crops to be delayed or deformed.

[0004] CN220402817U discloses a fruit fly automatic monitoring device. The fly trapping balls of this monitoring device must be manually replaced, and long-term field monitoring cannot be achieved.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0025] Such as Figure 1 and Figure 2As shown, an embodiment of the utility model provides a fruit fly trapping device, including a trapping box 1, in which a driving shaft 2 and a driven shaft 3 are arranged; corresponding synchronous gears 4 are arranged on the driving shaft 2 and the driven shaft 3; the two synchronous gears 4 are connected by a synchronous belt 5; the driving shaft 2 is driven by a stepper motor; a sticky paper roll 6 is wound around the driving shaft 2 and the driven shaft 3; the sticky paper roll 6 is divided into a green sticky paper roll 7 and a yellow sticky paper roll 8 along the center line in the width direction.

[0026] In this embodiment, the stepper motor drives the driving shaft 2 to rotate through a coupling, and the driving shaft 2 drives the synchronous gear 4 set thereon to rotate; the synchronous gear 4 set on the driving shaft 2 and the synchronous gear 4 set on the driven shaft are connected through a synchronous belt 5; when the driving shaft 2 rotates, it can drive the driven shaft 3 to rotate.

[0027] The adhesive paper roll 6 is fixed to the driving shaft 2. One end of the adhesive paper roll 6 is unfolded, and the adhesive surface is turned outward and then fixed to the driven shaft 3 to form a sticky plane. When the control module issues an instruction, the stepper motor starts, and while the driving shaft 2 releases the adhesive paper, the driven shaft 3 retracts the adhesive paper, thereby completing the automatic replacement of the adhesive paper.

[0028] In this embodiment, in order to utilize the color-attracting characteristics of fruit flies and the preference of different types of fruit flies for different colors, the sticky paper roll 6 is divided into a green sticky paper roll 7 and a yellow sticky paper roll 8 along the center line in the width direction, so that more types of fruit flies can be trapped and the trapping effect is better. As another embodiment, several sticky paper rolls 6 can also be fixed on the driving shaft 2, and the fly-sticking surfaces of the several sticky paper rolls 6 have different colors. This method makes it more convenient to replace the sticky paper rolls.

For example, in this embodiment, the photovoltaic panel 10 is controlled by a solar controller, and the solar controller is a maximum power point tracking solar controller (MPPT); the arm-integrated battery 11 and the solar controller are built into the arm battery cabin made of steel structure, and the cabin is used as a connecting arm to connect the photovoltaic panel 10 and the pole 9 together; the pole 9 is made of a hollow steel pipe, and the bottom is connected to the embedded parts and fixed on the ground.

[0039] As Figure 4 shown, when the present utility model uses the industrial camera 14 to monitor and identify fruit flies, it is carried out by the following method.

[0040] 1) Start the system and run the monitoring system control program. The remote server establishes a connection with the vision controller through the USB WIFI module for communication;

[0041] 2) Obtain temperature and humidity data;

[0042] 3) Turn on the fill light and prepare to collect fruit fly images;

[0043] 4) Collect fruit fly images, and the two industrial cameras respectively take the current frame of images;

[0044] 5) Set according to requirements in the monitoring system control program, save the collected fruit fly images to the local or upload them to the remote server, and the picture saving format is JPEG;

[0045] 6) The stepper motor starts, performs a sticker replacement once, and calculates the replacement times i. At this time, i = 1;

[0046] 7) Reassign the value of i;

The picture background also includes other similar non - target pests, and perform manual annotation to establish a fruit fly data set;

[0052] 2) Based on the YOLOv5s model as the basic model, use the established fruit fly database to train the fruit fly detection model;

[0053] 3) Since the detection effect of the fruit fly model in step 2 still cannot meet the requirements of the present utility model, the model is improved. The improvement strategies include the improvement of the activation function, the improvement of the coordinate attention mechanism, the improvement of the loss function and the improvement of data augmentation. The improved model is named YOLOv5 - FCGM;

[0054] 4) When the fruit fly image to be detected is loaded into the model, use the YOLOv5 - FCGM model for detection and counting, and finally give the types and corresponding quantities of the detected fruit flies.
