Large-scale pig farming requires the use of modern scientific and technological means to strengthen the management of all aspects of pig farming in order to reduce costs, improve efficiency, and promptly detect abnormal behaviors of pigs. It uses artificial intelligence, big data, sensors and other technologies to monitor pig behavior information in real time and identify pig behavior, so that corresponding measures can be taken in a timely and targeted manner.

[0003] In order to improve the production efficiency and economic benefits of pig farms, pig farms need to combine advanced breeding technology and feeding management methods to breed fast-growing and high-yield breeding pigs, and use monitoring technology to monitor and record the breeding behavior of breeding pigs in the pig farm, so as to timely understand the breeding progress of breeding pigs in the pig farm and effectively control the breeding scale of breeding pigs in the pig farm.

[0004] In the prior art, in order to monitor and record the breeding behavior of breeding pigs, cameras are generally installed in various areas of the pig farm.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention provides a breeding behavior monitoring device for fast-growing and high-yielding breeding pigs, comprising a main track 1 and a secondary track 2 installed in parallel on the top of a breeding farm. Generally, the main track 1 is used as an inspection track, and at least two inspection seats 3 slide on the main track 1. The inspection seats 3 are equipped with cameras 4, and the cameras 4 follow the inspection seats 3 to complete inspections in the direction of the main track 1.

[0022] The length of the main track 1 satisfies the condition that the image acquired by the camera 4 throughout the entire process can cover the entire farm. Assuming that the main track 1 and the auxiliary track 2 are arranged along the length direction of the farm, and the camera 4 cannot fully capture the comprehensive image in the width direction, multiple groups of main tracks 1 and auxiliary tracks 2 can be set along the width direction of the farm to perform corresponding inspection actions on each main track 1 and auxiliary track 2.

[0023] The main track 1 is composed of a plurality of first track segments 5 connected end to end, and the auxiliary track 2 is composed of a plurality of second track segments 6 connected end to end. The first track segments 5 correspond to the second track segments 6 one by one, and the second track segments 6 can be replaced by the first track segments 5.

[0024] like Fig.15 As shown, each pair of relative first track segments 5 and second track segments 6 can move synchronously in a direction perpendicular to the main track 1, so that the first track segment 5 is separated from the main track 1, the second track segment 6 is moved onto the main track 1 and connected with other first track segments 5 on the main track 1 to form a new inspection track.

[0025] When a new detection track is formed, the first track segment 5 in the original position will move a distance in the direction perpendicular to the main track 1, and the position of the camera 4 will be adjusted accordingly and leave the position of the inspection track. That is to say, the camera 4 needs to remain still for a period of time and record the breeding behavior of the breeding pigs. After adjusting the position, the shooting range of the camera 4 will not be greatly adjusted.

[0026] In order to adjust the position of the first track segment 5 and the second track segment 6, a position adjustment driving structure 7 is provided on each pair of the first track segment 5 and the second track segment 6. The position adjustment driving structure 7 connects the first track segment 5 and the second track segment 6 and can synchronously drive the first track segment 5 and the second track segment 6 to move in a direction perpendicular to the main track 1. Among them, the camera 4 follows the inspection seat 3 to slide on the first track segment 5 to inspect different areas in the farm. When the camera 4 observes the breeding behavior between individual breeding pigs, the inspection seat 3 stops sliding on the first track segment 5 and continues to record the individual breeding behavior images of the breeding pigs. The first track segment 5 and the second track segment 6 corresponding to the position of the camera 4 are driven to move by the adjustment drive structure 7 to obtain a new inspection track. The new camera 4 follows the inspection seat 3 to slide on the new inspection track to continue the inspection of different areas in the farm.

[0027] Camera 4 is generally connected to an image recognition module. Camera 4 sends the collected video files to the image recognition module. After frame extraction and image compression processing, the behavior analysis and recognition module performs behavior classification and recognition on the compressed images and performs offline training and update on the classification model, and outputs the classification and recognition results to the control platform.

[0028] In addition, an infrared sensor element can be installed on each inspection seat 3 to obtain the real-time position of the inspection seat 3. When the above classification and identification result is that the breeding pigs are engaged in breeding behavior, the control platform obtains the current position of the inspection seat 3, adjusts the position of the first track segment 5 and the second track segment 6 corresponding to the current position, and stops the inspection action of the camera 4. The camera 4 remains stationary and continues to record images of the breeding behavior of the breeding pigs, while other cameras 4 continue to perform inspection actions.

[0029] In the present invention, the main track 1 is used as the inspection track, and the camera 4 is driven by the inspection seat 3 to slide along the main track 1. The inspection monitoring method can effectively reduce the number of cameras 4 required and reduce energy consumption. The actions of individual breeding pigs are identified during the inspection process. When reproductive behavior is observed between individual breeding pigs, the inspection action is stopped and the reproductive behavior of the individual breeding pigs is recorded, thereby ensuring the validity of the data.

[0030] In addition, when one of the cameras 4 stops patrolling, Fig.15 As shown, a new inspection track is formed by adjusting the positions of the first track segment 5 and the second track segment 6, and another camera 4 is started to continue the inspection action in the direction of the new inspection track to avoid missing the breeding behavior of breeding pigs in other breeding areas and ensure the comprehensiveness of the inspection of breeding behavior of breeding pigs.

[0031] In the present invention, in order to ensure that different inspection seats 3 run smoothly on different first track segments 5 and second track segments 6, it is necessary to make: the lengths of the main track 1 and the auxiliary track 2 consistent, the lengths of each pair of relative first track segments 5 and second track segments 6 consistent, and the cross-sections of each first track segment 5 and second track segment 6 the same.

[0032] In the present invention, the positioning drive structure 7 connects the first track segment 5 and the second track segment 6, and can synchronously drive the first track segment 5 and the second track segment 6 to move in a direction perpendicular to the main track 1. Specifically, Figure 3 , Figure 4 and Figure 5 As shown, the position adjustment driving structure 7 includes a driving frame 701, a first slideway 702 and a second slideway 703 arranged on the driving frame 701; The driving frame 701, the first slide 702, and the second slide 703 are all arranged in a direction perpendicular to the main track 1. A top frame 8 is installed at the bottom of the driving frame 701. The driving frame 701 is installed on the top frame 8. A movable seat 704 is slidably installed on the first slide 702. The bottom of the movable seat 704 is connected to the first track segment 5 and the second track segment 6 through a connecting rod 705.

[0033] During the sliding process of the movable seat 704 on the first slideway 702 , the first track segment 5 and the second track segment 6 are driven to move in a direction perpendicular to the main track 1 through the connecting rod 705 .

[0034] Among them, the top frame 8 is generally fixedly installed on the top frame in the breeding farm.

[0035] For the connecting rod 705 to pass through, as Figure 6 As shown, a through slot 706 for the connecting rod 705 to pass through is provided in the first slideway 702 , and the width of the through slot 706 is smaller than the width of the movable seat 704 , so that the movable seat 704 can slide over the through slot 706 without falling from the through slot 706 .

[0036] In the present invention, the inspection seat 3 is a square frame structure, and the inspection seat 3 can be sleeved outside the first track section 5 and the second track section 6 and slide. Fig.10 As shown, an opening 9 is provided on the inspection seat 3 for the connecting rod 705 to pass through. The design of the opening 9 can effectively avoid interference between the inspection seat 3 and the connecting rod 705 , which causes the connecting rod 705 to hinder the sliding action of the inspection seat 3 .

[0037] To ensure that the first track segment 5 and the second track segment 6 can be reset after the camera 4 has finished recording the breeding behavior of the sow, the movable seat 704 can be reset to the initial position. Specifically, Figure 6 , Figure 7 , Figure 8As shown, a mounting seat 707 is installed on the end of the first slideway 702, and a limiting rod 708 is connected to the mounting seat 707. The limiting rod 708 is arranged along the direction of the first slideway 702; A connecting spring 709 is connected between the mounting seat 707 and the movable seat 704, and the end of the connecting spring 709 is sleeved outside the limiting rod 708; A strong magnetic block 710 is installed on the end of the first slide 702 away from the mounting seat 707, and a magnet 711 is connected to the end of the movable seat 704. The magnet 711 is opposite to the strong magnetic block 710, and the end of the magnet 711 is connected to a limiting bolt 712. The strong magnetic block 710 is provided with a through hole 713 for the limiting bolt 712 to penetrate.

[0038] The above two reset driving modes are adopted to reset the movable seat 704. The first mode is through the elastic force of the connecting spring 709. During the movement of the movable seat 704, the connecting spring 709 is gradually squeezed, and the movable seat 704 is also continuously subjected to the elastic force of the connecting spring 709. During the reset process of the movable seat 704, the movable seat 704 can be reset to the initial position under the action of the elastic force of the connecting spring 709. However, since the connecting spring 709 will drive the movable seat 704 to swing back and forth several times, the first track segment 5 and the second track segment 6 may be unstable in resetting. In this regard, there is also a second resetting drive method, specifically: the movable seat 704 is reset by magnetic attraction. During the movement of the movable seat 704, the strong magnetic block 710 generates a magnetic attraction force on the magnet 711. During the resetting process of the movable seat 704, the magnet 711 is directly attached to the strong magnetic block 710 due to the magnetic attraction force of the strong magnetic block 710, and the movable seat 704 can be reset to the initial position and will not swing under the action of the strong magnetic force.

[0039] Although both methods play a role in resetting and driving, the two methods complement each other to achieve the effect of stable resetting of the movable seat 704. From the perspective of a single driving and resetting process, when the movable seat 704 moves away from the strong magnetic block 710, the magnetic attraction will weaken due to the increase in distance. It is possible that after the distance is increased to a certain extent, the magnetic attraction cannot provide effective assistance for the resetting process of the movable seat 704. Therefore, the main function of the connecting spring 709 is to provide a driving force for the resetting of the movable seat 704, so that the movable seat 704 can be reset. The magnetic force of the strong magnetic block 710 gradually increases the magnetic attraction due to the decrease in distance during the process of the movable seat 704 being forced to reset, and the magnet 711 is firmly attracted by the magnetic attraction to prevent swinging, thereby ensuring the end of the resetting process and the stability of the entire resetting process.

[0040] To further ensure the resetting effect, it can be made so that: when the strong magnetic block 710 adsorbs the magnet 711, the connecting spring 709 is just in a natural state and does not produce elastic pulling force on the movable seat 704. At this time, the movable seat 704 is not subjected to any resistance in the opposite direction except the magnetic attraction force, thus avoiding the movable seat 704 being in an unstable state.

[0041] In order to drive the movement and reset of the movable seat 704, the present invention makes the following design: Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, a movable cavity 714 is provided in the movable seat 704 along the width direction, a slider 715 is slidably installed in the driving cavity, a connecting bolt 716 is connected to the end of the slider 715, the end of the connecting bolt 716 passes through the movable seat 704, a threaded bolt 717 is provided on the outer sleeve of the end of the connecting bolt 716, and the threaded bolt 717 is installed outside the movable seat 704, a return spring 718 is connected between the slider 715 and the inner wall of the movable cavity 714, and the return spring 718 is sleeved outside the connecting bolt 716; A connecting seat 719 is installed at the edge of the first slideway 702 and the second slideway 703. A stopper 720 is arranged on the connecting seat 719 at the end of the slider 715. A first inclined opening 721 is formed at the corner of the slider 715 facing the stopper 720. A second inclined opening 722 is formed at the corner of the slider 715 facing the stopper 720. The edges of the first inclined opening 721 and the second inclined opening 722 face each other and are parallel. A sliding seat 723 is slidably disposed in the second slideway 703 . A push rod 724 is disposed on the sliding seat 723 at a side close to the movable seat 704 . The push rod 724 is directly opposite to the slider 715 .

[0042] In the above embodiment, the sliding seat 723 slides along the second slideway 703 to drive the push rod 724 to gradually approach the slider 715. Fig.11 and Fig.12 As shown, after the push rod 724 directly contacts the slider 715, the slider 715 can be pushed to move, thereby pushing the movable seat 704 to move along the first slideway 702, until the slider 715 moves to the stop block 720 and stops moving. At this time, the position adjustment process of the first track segment 5 and the second track segment 6 has been completed; If the first track segment 5 and the second track segment 6 need to be reset, the sliding seat 723 needs to be pushed forward. Under the push of the push rod 724, the slider 715 contacts the stop block 720, and the first inclined opening 721 and the second inclined opening 722 are matched. Fig.13 and Fig.14As shown, as the first inclined opening 721 and the second inclined opening 722 slide relative to each other, the slider 715 will be gradually squeezed into the movable cavity 714 by the stop block 720, and the push rod 724 will continue to move forward. At this time, the push rod 724 can no longer drive the movable seat 704 to move through the slider 715, and the slider 715 has retracted into the movable cavity 714 at this time and is no longer subject to the thrust of the push rod 724. The movable seat 704 is only subject to the elastic force of the connecting spring 709 and the magnetic attraction of the strong magnetic block 710, and is quickly reset under the action of the external force, and then the push rod 724 follows the sliding seat 723 to reset.

[0043] During the process of the push rod 724 returning to its original position, the slider 715 will be pushed into the movable cavity 714 , but the movable seat 704 will not be pushed to move.

[0044] In the above embodiments, during the process of the push rod 724 pushing the slider 715 and during the process of the slider 715 retracting into the movable cavity 714 under the reaction force of the stop block 720, the push rod 724 does not interfere with the stop block 720. Specifically, the thickness of the stop block 720 is smaller than the thickness of the slider 715, and the height position of the stop block 720 is higher than the height position of the push rod 724.

[0045] In addition, in order to drive the movement of the sliding seat 723, the present invention has the following design: a first driving motor 725 is arranged on the driving frame 701 at a position corresponding to the second slideway 703, a screw rod 726 is connected to the driving end of the first driving motor 725, the screw rod 726 is threadedly matched with the sliding seat 723, a bearing seat 727 is arranged at the inner end of the second slideway 703, and the end of the screw rod 726 is rotatably mounted on the bearing seat 727; The first driving motor 725 is driven to drive the screw rod 726 to rotate and drive the sliding seat 723 to move, and the push rod 724 follows the movement and pushes the slider 715 and the movable seat 704 to move together after contacting the slider 715 until the slider 715 moves to the stop block 720 and stops.

[0046] In the present invention, in order to stop the movement of the sliding seat 723 before the movable seat 704 is reset, the present invention makes the following design: a wall groove 728 is opened on the bearing seat 727, a telescopic seat 729 is connected to the wall groove 728 through a telescopic spring, and a pressure sensor is installed on the telescopic seat 729; an extrusion block 730 is installed on the wall surface of the sliding seat 723 facing the telescopic seat 729.

[0047] When the slider 715 moves to the stop block 720, the extrusion block 730 just contacts the pressure sensor on the telescopic seat 729, and the pressure sensor detects pressure data. At this time, the signal can be transmitted to the control platform, and the control platform controls the first drive motor 725 to stop moving.

[0048] The pressure sensor can be regarded as a sensing element for detecting whether the first track segment 5 and the second track segment 6 have been adjusted. Ignoring the time of signal transmission, when the second track segment 6 coincides with the corresponding first track segment 5, the movable seat 704 just stops moving.

[0049] Overall, the first track segment 5 and the second track segment 6 have the following two movement processes: (1) When breeding behavior is observed in sows: In the position adjustment drive structure 7 corresponding to the current position of the camera 4, the first drive motor 725 drives the screw 726 to rotate and drives the sliding seat 723 to move. Fig.11 and Fig.12 As shown, the push rod 724 follows the movement and pushes the slider 715 and the movable seat 704 to move together after contacting the slider 715, until the slider 715 moves to the stop block 720; At this time, the squeezing block 730 contacts the pressure sensor, and the pressure sensor detects the pressure data and transmits the signal to the control platform, and the control platform controls the first driving motor 725 to stop moving, and the sliding seat 723 and the movable seat 704 both stop moving; During this process, the first track segment 5 and the second track segment 6 follow the movement and adjust their positions. After the position adjustment is completed, the first track segment 5 at the current position is separated from the main track 1, and the second track segment 6 moves to connect with the other first track segments 5 of the main track 1 to form a new inspection track. Another camera 4 can perform inspection along the new inspection track. (2) After recording the breeding behavior of the sows: The first driving motor 725 drives the screw rod 726 to rotate and drives the sliding seat 723 to move, and the push rod 724 pushes the slider 715 forward to move. Fig.13 As shown in FIG. 1 , under the relative sliding of the first inclined opening 721 and the second inclined opening 722, the slider 715 is gradually squeezed into the movable cavity 714 by the stop block 720 (it may not be completely retracted into the movable cavity 714). At this time, the slider 715 has been retracted into the movable cavity 714 and is no longer pushed by the push rod 724. The movable seat 704 is only subjected to the elastic force of the connecting spring 709 and the magnetic attraction of the strong magnetic block 710, and is quickly reset under the action of the external force (as shown in FIG. 1 ). Fig.14 shown); After the movable seat 704 is reset, the first driving motor 725 rotates in the reverse direction to drive the sliding seat 723 to reset to the initial position.

[0050] In order to realize the inspection of the inspection seat 3, the present invention makes the following design, such as Fig.10As shown, side grooves 10 are opened on both sides of the bottom of the first track section 5 and the second track section 6, and a rack 11 is installed in the side groove 10. A second drive motor 12 is installed outside the inspection seat 3. The drive shaft of the second drive motor 12 is connected to a drive gear 13. The drive gear 13 is arranged in the inspection seat 3 and meshes with the rack 11.

[0051] The second driving motor 12 drives the driving gear 13 to rotate. The rotation of the driving gear 13 causes the driving gear 13 and the rack 11 to move relative to each other. When the rack 11 remains stationary, the driving gear 13 and the inspection seat 3 move along the first track section 5 and the second track section 6.

[0052] To ensure smooth operation of the inspection seat 3, a plurality of ball grooves 14 are provided on the inner walls of the top and sides of the inspection seat 3 opposite to the first track section 5 and the second track section 6. Balls 15 are rotatably installed in the ball grooves 14, and the balls 15 are in rolling contact with the outer walls of the first track section 5 and the second track section 6.

[0053] Under the action of the driving force, the inspection seat 3 moves on the first track section 5 and the second track section 6 in a rolling manner.

[0054] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
