Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.

According to the bait throwing control system, the bait throwing device is installed in the culture pond, and the maximum range of bait throwing of the bait throwing device is a shoal feeding area. According to the area size of the culture pond and the fish amount cultured in the culture pond, a plurality of feeding devices with a certain distance can be arranged in the culture pond, namely, a plurality of feeding areas for fish schools are arranged. Generally, depending on the normal living characteristics of the fish, the fish will move into the baiting zone and eat while hungry, and will generally leave the feeding zone after eating. According to the bait throwing control system, the bait throwing amount is controlled according to the number of the fish school in the feeding area, so that on one hand, the phenomenon that the fish school is hungry due to small bait throwing amount is avoided, and the fish school is not beneficial to growth of the fish school; on the other hand, the situation that excessive bait is thrown to avoid being eaten by fish schools and causing waste is avoided, and the redundant bait stays in the culture pond to cause pressure to the culture water body.

As shown in fig. 1 and 2, a bait throwing control system according to an aspect of the present invention includes a control device, and a fish group monitoring device and a bait throwing device controlled by signals from the control device. The fish school monitoring device monitors fish schools in the feeding area on the water surface and sends fish school signals to the control device, and the control device judges the fish school area and the fish school density according to the fish school signals to control the feeding speed, the feeding area and the feeding time of the feeding device, wherein the fish school signals mainly refer to the density of the fish schools in the feeding area or the distribution area of the fish schools in the feeding state in the feeding area. Adopt two indexes of density and area here to control the device of feeding, on the one hand effectual assurance is thrown the food consumption and is adapted to fish quantity, and on the other hand ensures to put in bait on the fish school region of eating for bait can be timely by the fish school edible, avoids bait too far away and can not be timely by edible apart from the fish of eating, falls to the bottom of the pool, causes the bait extravagant and still causes pressure to the water environment of breed.

In this technical scheme, controlling means includes fish volume judgement module, and fish volume judgement module judges fish shoal area and fish shoal density in the food intake region. The fish amount judging module analyzes the fish school area and the fish school density in the feeding area, transmits the result to the central processing unit, and controls the feeding speed, the feeding area and the feeding time of the feeding device through the central processing unit. The method specifically comprises the following steps: the fish amount judging module marks and colors each fish image on a fish school photo in a feeding area transmitted by a CCD industrial camera, then divides the whole range of the photo, counts the number of the fish images in each division range to obtain the fish school density in each division area, takes continuous areas with large density as the fish school area of the feeding fish, controls bait to be thrown and sprinkled on the fish school area, and then controls the bait throwing speed and time according to the fish school density in the areas.

Referring to fig. 1 and 2, the feeding device comprises a bait conveying screw 6 and a bait lifting fan 5, wherein a servo bait conveying motor 3 and a servo bait lifting motor 4 are respectively connected to the bait conveying screw 6 and the bait lifting fan 5, and the servo bait conveying motor 3 and the servo bait lifting motor 4 are controlled by a control device. The control device controls the working speeds of the bait conveying screw rod 6 and the poplar bait fan 5 respectively by controlling the rotating speeds of the servo bait conveying motor 3 and the servo bait raising motor 4, namely, the control of the bait conveying efficiency and the bait conveying amount of the bait conveying screw rod 6 is realized, the bait raising speed and the bait raising height of the poplar bait fan 5 are controlled, and the bait is raised to different heights to control the raising of the bait on the area of a fish school not used, namely, in different areas far away from the bait feeding device.

As shown in fig. 1, the control device comprises a central processing unit, a signal receiving module, a signal sending module, a fish amount judging module and a fish school monitoring control module. The fish shoal monitoring control module controls the working time of the fish shoal monitoring device, namely the time for pressing the shutter of the CCD industrial camera. Because the fish shoal takes a certain time length for eating, the change of the area and the density of the fish shoal which is eaten is not instantaneous, namely, the CCD industrial camera does not need to continuously shoot the fish shoal, thereby avoiding increasing the working pressure of the CCD industrial camera and the control device.

As shown in fig. 1, the fish shoal monitoring device includes a CCD industrial camera, and a shutter of the CCD industrial camera is controlled by a fish shoal monitoring control module by a conventional control method in the prior art. The CCD industrial camera shoots the fish school in the feeding area, the picture signal is transmitted to a fish quantity judging module in the control device, the fish quantity judging module analyzes the area and the density of the fish school on the fish slice to obtain the real-time feeding fish quantity, and the signal is transmitted to the central processing unit.

Referring to fig. 2, the feeding device comprises a bait bucket, a bait conveying pipe 2 is connected to the bottom of the bait bucket, a bait conveying screw rod 6 is arranged in the bait conveying pipe 2, and a bait raising fan 5 is connected to the other end of the bait conveying pipe 2. A bait quantity sensor 7 is arranged in the bait bucket 1, and a bait quantity alarm is connected to the bait quantity sensor 7. The bait quantity sensor is a pressure sensor and is installed in the bait bucket 1 near the bottom. The pressure sensor monitors the bait in the bait bucket 1, and the alarm is given when the bait is about to be used up, so that the worker is reminded to supplement the bait in time.
