The invention discloses a pathological image segmentation method based on a U-Net model of an improved encoder and decoder, and the method comprises the following steps: carrying out the preprocessing of data, and improving the generalization capability of a model; a U-Net model encoder and a U-Net model decoder are improved, and an EEDU-Net model is established; training the model by using the training set data; optimal model parameters are obtained, test set data are input, and a prediction result of the model is subjected to visualization processing. According to the invention, each layer of encoder is changed into a multi-branch form, so that the capability of encoding to extract information of different scales is improved. And meanwhile, semantic differences are eliminated through channel attention and axial attention processing on the feature map subjected to jump connection, and the effectiveness of each jump connection is ensured. The robustness and precision of pathological image segmentation are improved by using the EEDU-Net model, and a segmentation effect superior to that of an existing model is shown.

The application discloses a short-term accurate prediction method for tuna longline fishing center fishing ground and hooking route based on middle layer water temperature and ocean current spatial characteristics, and has the characteristics that the fishing ground position is accurately predicted according to the spatial vortex characteristics of the middle layer water temperature (reference 100m water layer, auxiliary reference 50m water layer) and the ocean current (preferably the ocean current of the 100m water layer, auxiliary reference the ocean current of the 50m water layer), and the hooking route is designed according to the method that the hooking route is maximally 90 degrees with the 100m water layer ocean current. The application can accurately predict the fishing ground position and the hooking route by combining the marine environment and the tuna longline fishing boat operation characteristics, and can improve the catch by 10-20% and improve the production effect.

The utility model discloses a safe, efficient and convenient automatic fish-pricking and fishing device for a fishing buoy, and relates to the technical field of fishing tools. And the top of the shell is fixedly connected with a sealing ring. The safe, efficient and convenient automatic fish-piercing and fish-getting-up device for the fishing buoy is very convenient and rapid to use and compact in structure, and the top end of the upper portion of the fish-piercing buoy is further provided with a striking fully-closed hollow plug-in type buoy, a hemispherical floating ball device, a foam fluorescent floating eye and a lamplight warning device. The automatic rebounding fish-piercing buoy can ensure that the line inlet and outlet ports of the buoy face downwards under the conditions of any water area and weather water depth, the buoy eye is clear and the buoy is vertically suspended on the water surface so as to adapt to the fishing environment of any water area, under the condition that a fisherman adjusts the buoy and the water depth, bait is thrown into water, and fishes on the fisherman are automatically hooked, and in addition, the automatic rebounding fish-piercing buoy is convenient to use. The lead eating amount can be effectively reduced, the vigor of a fisherman is relieved to the maximum extent, and the fish obtaining is effectively increased.

This utility model discloses a fishing device for fish identification, belonging to the technical field of fishing devices. It includes an L-shaped main board with a fishing mechanism inside. The fishing mechanism includes an electric push rod embedded in the inner left wall of the L-shaped main board. A fishing frame is fixedly installed at the telescopic end of the electric push rod. A fish inlet corresponding to the fishing frame is fixedly installed on the inner rear wall of the L-shaped main board, and a fish storage cage is installed to the right of the fish inlet. Through the fishing mechanism, this utility model can dynamically capture and identify fish using a visual sensor. The electric push rod is controlled by a controller, causing the fishing frame to move to the right, trapping the fish inside. Then, the rightward movement of a push plate pushes the fish through the fish inlet and the fish-blocking plate into the fish storage cage. This process repeats, achieving automatic fishing. The principle is simple while improving the fishing yield.

The utility model discloses a variable-amplitude positioning device for a gantry crane, which belongs to the technical field of harbor machinery and is characterized in that a rotating mechanism comprises an outer gear ring, a gear and a motor, the outer gear ring is fixedly sleeved on the outer wall of a fixed ring, an upper rotating ring is in running fit with the outer wall of the upper end of the fixed ring, and a lower rotating ring is sleeved on the gear. The lower rotating ring is rotationally matched with the lower end outer wall of the fixed ring; the upper rotating ring is connected with the inner end of the upper connecting plate, the lower rotating ring is connected with the inner end of the lower connecting plate, the outer end of the upper connecting plate and the outer end of the lower connecting plate are connected with the induction magnets through the rotary reset mechanisms respectively, the positions from the two induction magnets to the circle center of the fixing ring are the same, and the heights of the two induction magnets are the same. And the magnetic induction limit switch is connected with a rotary column of the gantry crane through a connecting frame and is placed above the induction magnet. Compared with the prior art, the material grabbing and discharging device has the characteristic of improving the material grabbing and discharging precision.

The utility model relates to the technical field of fishhooks, in particular to a squid hook, which comprises a buoyancy bar in a strip-shaped structure. The light-emitting part is stacked on the outer surface of the buoyancy rod and is used for attracting squids in a night fishing environment; the hook part is arranged at one end part of the buoyancy rod and is used for capturing the attracted squids; and the hook handle is arranged at the other end part of the buoyancy rod and is used for binding and installing a fishing line. The squid hook solves the problems that when a paper or cloth fiber body is adopted as a squid hook main body in the prior art, the self-weight of a bent hook piece and a hook handle is large, a buoyancy device does not exist, and the squid hook cannot float in water, so that squids are difficult to attract for a long time, and the fish obtaining is influenced.
