Description

Technical Field

[0001] This invention relates to the field of livestock and poultry breeding inspection technology, and in particular to a livestock and poultry house inspection device. Background Technology

[0002] With the transformation and upgrading of modern animal husbandry, new requirements have been placed on the feeding and management of caged livestock and poultry houses. During livestock and poultry house inspections, in order to monitor the health status of livestock and poultry in real time and ensure that the cage environment is maintained at an optimal level for their survival, regular inspections are necessary. The growth and health status of livestock and poultry in each cage must be recorded. With the further development of image detection, higher requirements have been placed on livestock and poultry image detection, such as establishing long-term, reliable data to determine whether livestock and poultry are pregnant or exhibiting abnormal symptoms in the early stages of disease. This necessitates a stable and efficient image acquisition and inspection device.

[0003] Existing traditional livestock and poultry house inspection robots are mostly inspection carts. Because they move in aisles, detection and positioning are time-consuming and inefficient. They also occupy aisles during inspections, preventing staff from performing other work in the livestock and poultry houses. Furthermore, uneven aisle floors make it more difficult to accurately position the carts and maintain consistent image acquisition standards at the same location at different times, which also increases the time cost of subsequent image processing. The inspection carts also generate a lot of noise during their movement, which can easily cause stress reactions in livestock and poultry and may affect their health. Summary of the Invention

[0004] The purpose of this invention is to provide a livestock and poultry house inspection device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A livestock and poultry house inspection device includes a steel cable assembly installed above the livestock and poultry house, and a mobile platform that moves on the steel cable assembly. The mobile platform is connected to a detector for acquiring images of livestock and poultry. The steel cable assembly includes an X-direction steel cable and a Y-direction steel cable, and a bending connector disposed between the X-direction steel cable and the Y-direction steel cable for the mobile platform to turn.

[0006] Furthermore, a telescopic sleeve is connected between the mobile platform and the detector, and the telescopic sleeve moves in the vertical direction.

[0007] Furthermore, an outer swing arm that can rotate around the telescopic sleeve is fitted on the telescopic sleeve. The outer swing arm can move up and down on the telescopic sleeve, and the detector two is connected to the outer swing arm.

[0008] Furthermore, the telescopic sleeve is also connected to a cross-line mechanism, which includes a base, a position control sensor switch, and a limit switch mechanism, with the limit switch mechanism mounted on the base.

[0009] Furthermore, the limit switch mechanism includes an energized upper magnet, an energized lower magnet, a rotary connector, and a magnet connector; the rotary connector and the magnet connector are arranged perpendicularly, and the magnet connector is used to drive the energized upper magnet to swing; the energized upper magnet is an energized demagnetizing magnet, when the position control sensor detects a turning position, it triggers the energized upper magnet to lose its magnetism, the energized upper magnet and the energized lower magnet are disconnected, and a gap is created between the energized upper magnet and the energized lower magnet, allowing the energized upper magnet to move; when the position control sensor receives a pass signal, it de-energizes the energized upper magnet to restore its magnetism, and the energized upper magnet and the energized lower magnet remain connected; the position control sensor is a photoelectric switch or a limit switch.

[0010] Furthermore, the limit switch mechanism includes a main hook, a secondary hook, and a servo motor; when the position control sensor detects the cornering position, it sends a signal to the servo motor, which controls the main hook and the secondary hook to open and close sequentially; at least one main hook and at least two secondary hooks are set, and two hooks are kept in a combined state during the cornering process.

[0011] Furthermore, the cable assembly also includes a cable hook, one end of which is connected to the Y-direction cable, and the other end is fixed to the roof of the livestock shed.

[0012] Furthermore, the cross-line mechanism is equipped with environmental sensors to detect and collect the necessary environmental information.

[0013] Furthermore, the mobile platform is equipped with photoelectric sensors to record the real-time travel distance of the inspection device.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. The livestock and poultry house inspection device of the present invention uses a mobile platform to move the entire inspection device along a set steel cable inside the livestock and poultry house, completing the identification of target objects and the collection of environmental data. The steel cable, positioned above the livestock and poultry house, ensures smooth operation, minimizes interference with livestock and poultry workers, reduces the impact on livestock and poultry, and achieves high inspection efficiency. It also facilitates subsequent data collection and reduces the difficulty of data processing. The use of a bending connector allows the inspection device to automatically complete the inspection process under the drive mechanism. 2. The telescopic sleeve allows the detector connected to it to move vertically to meet the detection needs at different detection positions and heights.

[0015] 3. An external swing arm that can rotate around the telescopic sleeve and move up and down is fitted on the telescopic sleeve, which can meet the requirement of simultaneously detecting multiple livestock and poultry cages and adjusting the detection position according to the position of the livestock and poultry cages.

[0016] 4. The cross-line mechanism allows the inspection device to move its outer swing arm upwards when it is moving to a bend at the end with the feeder. This ensures that the detector connected to it is raised to a sufficient height during the subsequent rotation to avoid hitting the upper livestock cage. The cross-line mechanism can also use the same cross-line method during the inspection to avoid other unremovable connections, such as power lines and hanging wires.

[0017] 5. The steel cable hook is designed to keep the steel cable taut during the inspection process as the inspection device moves upwards, ensuring that the steel cable does not sag excessively and affect the inspection.

[0018] 6. Depending on the specific needs, environmental sensors and photoelectric sensors can be installed at different locations on the inspection device to detect and collect the required environmental information or to record the real-time travel distance of the inspection device.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] It should be noted that in the description of this invention, the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0023] Furthermore, it should be understood that, for ease of description, the dimensions of the various components shown in the accompanying drawings are not drawn to actual scale; for example, the thickness or width of some layers may be exaggerated relative to other layers.

[0024] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be discussed or described in detail in the description of the subsequent figures.

[0025] The target of this invention is primarily the monitoring of health status and the environment during livestock and poultry farming. Stacked cage livestock and poultry houses typically consist of two layers of cages arranged in a triangular pattern along the height. Generally, four rows of cages are arranged within the house, each row being a stacked cage system with two layers, each layer containing two rows of cages in a triangular cross-section. Each row of cages has a corresponding feeding box at the front, and a feeder approximately twice the height of the cage frame is located at the rear end of each row. Due to the large number of cages requiring monitoring, traditional inspection trolleys are time-consuming and inefficient when moving and positioning themselves in the aisles of the livestock and poultry house. They also occupy the aisles for extended periods, interfering with other work for the staff, and their operation is not smooth, generating significant noise that can easily cause stress in livestock and poultry, potentially affecting their health.

[0026] like Figure 1 As shown, the present invention provides a technical solution: a livestock and poultry house inspection device, including a steel cable assembly installed above the livestock and poultry house, and a mobile platform that moves on the steel cable assembly. The mobile platform is connected to a detector for image acquisition of livestock and poultry. The steel cable assembly includes an X-direction steel cable and a Y-direction steel cable, and a bending connector disposed between the X-direction steel cable and the Y-direction steel cable for the mobile platform to turn. The mobile platform 3 can move autonomously or under remote control signals by being mounted on the Y-direction steel cable 303, X-direction steel cable 304, and bending connector 302 arranged along the steel cable assembly. The mobile platform 3 uses two drive wheels 31, one in front and one in back. The diameter of the groove in the middle of the drive wheel 31 is slightly larger than that of the steel cable, so that it can hold the steel cable and then run smoothly. The drive wheel 31 is covered by a drive housing 32. The drive housing 32 is rotatably connected to the fixed plate 33, and there is a certain distance between the front and rear drive housings 32. Therefore, there is a certain distance between the front and rear drive wheels 31, so that when walking along the steel cable or bending, the front and rear drive wheels can rotate at a certain angle, making walking and bending smoother. The inspection device has low noise when moving on the walking steel cable, and it is further away from the livestock and poultry cages than the inspection trolley, which can avoid startling the livestock and poultry due to excessive noise.

[0027] The upper connecting arm 4 is installed on the fixed plate 33 of the mobile platform 3. The upper connecting arm 4 can be made of carbon fiber square tube or other high-strength square tube. Carbon fiber has a low density, which can meet the strength requirements of use, while being lightweight, which helps to reduce the load weight of the steel cable mobile platform 3. At the same time, the upper connecting arm has a certain degree of bending, so that the center of gravity of the overall inspection device and the center of the steel cable under load are roughly on the same vertical line, which increases stability and prevents tilting or overturning during travel.

[0028] The cross-line mechanism 5, connecting lower arm 6, telescopic sleeve, and outer swing arm 9 can also be made of carbon fiber or other high-strength materials to reduce the overall weight of the device while meeting the strength requirements.

[0029] The drive mechanism 10 includes a motor, battery power supply, etc. The drive mechanism 10 is installed in the gap between the two wheels of the cable moving platform or optionally installed above the fixed plate 33 to keep the center of gravity of the mechanism and the center of gravity of the whole device roughly on a vertical line, thus maintaining the balance of the whole device. The drive mechanism 10 drives the two drive wheels 31 to move along the cable. The structure of the drive mechanism 10 is not specifically limited, as long as it can drive the drive wheels to move up and down along the cable and through curves.

[0030] The lower arm 6 connects to the cross-line mechanism 5 and the telescopic sleeve 7 at both ends. The lower arm 6 also has a certain degree of curvature to ensure that the overall center of gravity of the inspection device is roughly on the same vertical line as the center of the steel cable under load. The telescopic sleeve can move vertically to meet the inspection needs at different inspection heights.

[0031] An outer swing arm that can rotate around the telescopic sleeve is fitted on the telescopic sleeve. The outer swing arm can move up and down on the telescopic sleeve. The detector is connected to the outer swing arm. During the detection, the position of the outer swing arm is automatically controlled to change according to the detection position reached by the automatic sensing device to ensure that the inspection device can smoothly complete the bend.

[0032] like Figure 2 As shown, in one embodiment, the crossing mechanism 5 is installed between the connecting upper arm 4 and the connecting lower arm 6, including a base 55, a position control sensing switch, and a limit switch mechanism. The limit switch mechanism is installed on the base 55. The limit switch mechanism serves to avoid the obstacle line. Its rotating connector 54 is connected to the auxiliary arm extending from the connecting upper arm 4, and is used to drive the magnet connector 53 and the energized upper magnet 52 to rotate when passing the obstacle line. The magnet connector 53 is connected to the rotating connector 54, and the energized upper magnet 52 is fixed at the lower part, which is used to drive the energized upper magnet 52 to swing when passing the obstacle line.

[0033] Specifically, the four energized magnets 52 are arranged in a cross shape from a top view to avoid collisions and interference caused by excessive upward swing angles when crossing the obstacle line. The energized magnets 52 are fitted with inclined sleeves to better change the angle of contact force when touching the obstacle line, allowing for smoother swinging to pass through the obstacle line.

[0034] The base 55 of the cross-line mechanism 5 is fixed on the connecting lower arm. Four energized lower magnets 51 are arranged on the base 55 according to the position of the energized upper magnet 52. When not energized, the energized upper magnet 52 and the energized lower magnet 51 remain connected.

[0035] like Figure 3As shown, in another embodiment, the crossing mechanism 13 includes a base 134, a position control sensing switch, and a limit switch mechanism, with the limit switch mechanism mounted on the base 134. The limit switch mechanism serves to avoid obstacle lines and includes a servo motor 133, a main hook 131, and auxiliary hooks 132. The connecting upper arm has three auxiliary hooks arranged in the same row, each with custom-designed holes providing sufficient space for the hooks to open and close. The opening and closing direction of the main hook 131 is opposite to the direction of the two auxiliary hooks 132; simultaneously, the lines connecting the three hooks to the closed contact points of the connecting upper arm are ensured to be straight, with the main hook 131 located in the middle and the two auxiliary hooks 132 on either side; the spacing between the hooks is sufficient to accommodate the traveling steel cable and conventional electrical wires within the spacing.

[0036] It should be noted that, unless otherwise specified as manual adjustment, all control movements of the device mechanism are automatically programmed.

[0037] Driven by the drive mechanism 10, the drive wheel 31 of the cable-stayed moving platform 3 moves along the cable. When it reaches a specific livestock cage to be inspected, it stops moving. At this point, the detectors connected to the outer swing arm 9 and the telescopic sleeve 8 correspond to a livestock cage to be inspected, respectively, and collect data such as images. The outer swing arm 9 is used to inspect one side of the lowest layer of livestock cages, while the detector connected to the telescopic sleeve 8 inspects the upper layer of livestock cages on the same side as the one inspected by the outer swing arm. After the two livestock cages to be inspected are inspected, the drive mechanism 10 drives the cable-stayed moving platform 3 to move to the next adjacent livestock cage to be inspected. The above steps are repeated until one inspection route is completed, and the inspection device stops moving.

[0038] In embodiments of the present invention, such as Figure 7 As shown, when the device moves to the bend position with the feeder at one end, the outer swing arm 9 needs to be moved upward first to ensure that the detector 2 connected to it is raised to a sufficient height during the subsequent rotation to avoid hitting the upper livestock cage. Then, during the bend, the outer swing arm 9 is rotated around the axis of the telescopic sleeve at a certain angular velocity so that the outer swing arm 9 is always aligned with the line connecting the telescopic sleeve 8 in the top view direction and parallel to the Y-direction steel cable 303. After completing the bend, the outer swing arm 9 is rotated back above the livestock cage to be tested. Next, the outer swing arm 9 is moved downward until it reaches a height where the detection mechanism can stably detect the livestock cage, and then it remains stable to continue the detection task.

[0039] In one embodiment of the cross-line mechanism 5 of the present invention, such as Figure 2As shown, the crossing mechanism 5 is used to pass through the lower Y-direction steel cable 303 when crossing a curve. When the position control sensor switch senses the curve position, it sequentially controls the energized upper magnet 52 to turn on and off according to its distance from the Y-direction steel cable 303. When the nearest energized upper magnet 52 receives the energizing signal, it is powered on and demagnetized. At this time, the magnet connector 53 and the rotating connector 54 can move freely without constraints according to the position angle of the magnet contacting the steel cable, so as to ensure that the energized upper magnet 52 swings upward and rotates with minimal resistance, allowing the inspection device to pass through the steel cable. After passing through, the position control sensor switch receives the passing signal and disconnects the power supply to the energized upper magnet 52 that passed through the steel cable, so that the energized upper magnet 52 regains its magnetism and maintains its connection with the energized lower magnet 51. The curve is completed when all four energized upper magnets 52 have passed through the curve position. The four energized upper magnets 52 are arranged in a cross shape, which ensures that two magnets remain connected during the curve crossing process, thus ensuring the overall stability of the inspection device during the curve crossing process.

[0040] The crossover mechanism 5 can also avoid some other connections that cannot be removed during the inspection process, such as power lines and hanging wires, by adopting the same crossing method.

[0041] In another embodiment of the cross-line mechanism 5 of the present invention, such as Figure 3 As shown, when cornering, the position control sensor switch senses the cornering position and sends a signal to the servo motor 133 controlling the hook. The servo motor 133 controls the hook to open and close sequentially according to its distance from the Y-direction cable 303. After the first auxiliary hook 132 passes the cable, the inspection device moves to the interval between the hooks so that the Y-direction cable 303 is located, closes the auxiliary hook 132 that has passed the cable, and then opens the main hook 131. Similarly, during the cornering process, two hooks are always kept in a closed state to maintain the balance and stability of the mechanism when cornering.

[0042] The number of magnets or hooks can be increased depending on the weight of the mounted mechanism. If the number of magnets or hooks is not enough to stably guarantee the connection of the mechanism, the number of magnets or hooks can be increased or the arrangement can be changed to meet the connection requirements, provided that they do not interfere with each other. However, there should always be at least two magnets or hooks maintaining the connection at all times, and they should be able to remain stable.

[0043] Because the width of livestock and poultry cage frames may vary in different livestock and poultry houses, the outward distance of the outer swing arm 9 and the position of the telescopic sleeve may not meet the detection conditions of the detector for the livestock and poultry cages. Therefore, the connection between detector 1 and the telescopic sleeve 8, and between detector 2 and the outer swing arm 9, is a movable connection, which can be adjusted to a certain angle. Before the start of detection, a certain angle can be manually adjusted and fixed to meet the detection requirements. Similarly, the extension position of the telescopic sleeve can also be adjusted at the start of detection to meet the height requirements of the detection mechanism for the upper livestock and poultry cages.

[0044] The detector includes a camera component and a recognition component. The camera component comprises a camera unit, which can be a spectrometer fiber optic probe or an RGB camera. The camera component captures images of livestock and poultry inside the cages; these images can be multispectral or RGB images. The camera component, recognition device, and cable-stayed platform 3 are connected to a controller. As the cable-stayed platform 3 moves along the cable, the recognition device determines whether it has reached the predetermined shooting position for each livestock and poultry cage. If it has, the controller stops the cable-stayed platform 3, and the camera component then captures images or videos of the target inside the livestock and poultry house that meet the requirements. After the current target livestock and poultry cage has been photographed once, the controller continues to control the cable-stayed platform 3 to continue moving and photographing the next livestock and poultry house to be photographed. During the entire inspection process, no prior identification of the target objects is required by the staff. The identification and photographing operations are performed sequentially during the movement of the cable-stayed platform 3, which helps reduce the workload of the staff. Compared to inspection trolleys, this method offers higher shooting efficiency and accuracy, and more stable image capture. This image acquisition method is also suitable for time-phased livestock and poultry behavior studies, thus improving overall operational efficiency.

[0045] Furthermore, the detector is also equipped with a light source, which can be a visible light sensor or an infrared lamp, etc. When the light inside the livestock and poultry house is dim, the light source is turned on to provide suitable brightness illumination, which facilitates the camera component to take pictures, ensures image clarity, and improves the accuracy of target object recognition. The livestock and poultry house inspection device also includes an environmental sensor 12 and a photoelectric sensor 11; the environmental sensor 12 can be set in different locations to detect and collect some necessary environmental information of the livestock and poultry house; the photoelectric sensor 11 is set on the drive wheel housing of the mobile platform to record the number of rotations of the drive wheel 31, thereby recording the travel distance.

[0046] The environmental sensor 12 can be installed on the connecting upper arm 4, connecting lower arm 6, and outer swing arm 9, or simultaneously, depending on the selected environmental detection target, to meet the height position requirements of certain environmental detection targets; for example, temperature sensors, wind speed sensors, sound sensors, etc. can be selected. The collected data is remotely fed back to the control terminal based on whether the requirements are met; the photoelectric sensor 11 is used to record the number of revolutions of the drive wheel 31, thereby recording the travel distance. The distance can be compared with the length of the travel cable to determine whether there is slippage or abnormal movement of the device.

[0047] like Figures 4 to 6The cable arrangement shown is specifically designed for livestock and poultry sheds with a common layout. It features four rows of double-layered, triangular-shaped cages, each row containing four sheds. Two rows are located on the lower outer layer, and two rows on the upper inner layer. For this cable arrangement, the walking cables of each row are positioned in the middle of each shed. Due to the cable arrangement requirements, each Y-direction cable 303 cannot be cut in the middle; both ends must be fixed to the front and rear walls of the sheds. X-direction cables are located between the Y-direction cables of adjacent cages. From the top view, two X-direction cables 304 are arranged that are higher than and perpendicular to the Y-direction cables 303. The height of these cables is such that when the inspection device is at a bend, the height of the crossing mechanism 5 is approximately the same as the height of the Y-direction cables 303, thus fulfilling the purpose of the crossing mechanism.

[0048] The X-direction steel cable 304 must be fixed at both ends to the left and right walls and cannot be cut in the middle. In addition, the bending connector 302 between the X-direction steel cable 304 and the Y-direction steel cable 303 is made of carbon fiber or other high-strength materials, has a certain curved shape, is the same width as the steel cable or its maximum width is less than the width of the drive wheel groove, and has a circular cross-section, so that the inspection device can travel relatively smoothly on the bending connector 302 to transition from the Y-direction steel cable 303 to the X-direction steel cable 304 and complete the bending connection.

[0049] The specific travel route of the inspection device is as follows: Figure 6 As shown, the inspection device begins its inspection at any of the outermost rows of livestock cages, near the feeder. The bend at the end furthest from the feeder is positioned above the outside of the cage frame, while the bend at the end closest to the feeder is positioned in front of the feeder, above the cage frame, to avoid the inspection device being unable to pass the feeder. Based on the cable arrangement and the inspection device configuration, after one inspection cycle, half of the livestock cages in the shed have been inspected. Upon reaching the end of the cable, the outer swing arm 9 is automatically rotated so that the connected detector 2 aligns with the lower cage on the other side. The angles of detectors 1 and 2 facing the inspected cages are manually adjusted to prepare for the inspection of the remaining half of the cages.

[0050] like Figure 8 As shown, for the arrangement of the steel cables, a specific tensioning device is installed at each fixed point. The tensioning force is applied in three directions: parallel to the steel cable in two directions, and towards the outside of the fixed steel cable, to achieve overall fixation of the steel cable. The purpose is to reduce the sagging of the steel cable when the inspection device travels on the steel cable, and to reduce the degree of sagging if the distance between the fixed points is too far or unreasonable.

[0051] The arrangement and tensioning of the Y-direction steel cable 303, the X-direction steel cable 304 and the bend connecting members 302 are realized by arranging single-side steel cable hooks 301 at intervals. The single-side steel cable hook is L-shaped, the end of the long section is fixed to the roof, and the short section is used to support the steel cable. Meanwhile, according to the reasonably arranged interval distance calculated based on the length and width of different livestock and poultry houses and the overall weight of the inspection device, the steel cable hooks 301 keep the steel cable tensioned when the inspection device travels on the steel cable for inspection, and at least satisfy the condition that the steel cable does not sag too much to affect detection. In addition, when the inspection device travels on the steel cable, the connecting upper arm 4 of the inspection device shall be arranged on the side opposite to the vertical long section of the steel cable hook 301, so as to avoid collision and obstruction between the two that prevents the inspection device from moving forward.

[0052] In addition, the tensioning device at each fixed point shall be regularly inspected and re-tensioned to meet the inspection requirements for operation of the mechanism.

[0053] In another embodiment of the present invention, the traveling cable of the inspection device can be replaced with a cable formed by connecting square or round steel pipes. Steel pipes meeting strength requirements can be selected according to the final weight of the device, which eliminates the possibility of sagging, and the limit distance of support at both ends is much larger than that of cable support. The steel pipes are installed on the same horizontal plane, and there is no arrangement of vertically overlapping cables, which makes installation and disassembly easier and more convenient, and is suitable for installation and arrangement in more types of livestock and poultry houses.

[0054] In yet another embodiment of the present invention, the telescopic sleeve rod can be constituted by an electric push rod or other equipment capable of telescoping up and down, so as to realize automatic control of the entire detection process.

[0055] In yet another embodiment of the present invention, detectors can be added according to shooting requirements. For example, a connecting rod is added to the detector 1, another detector is placed on the connecting rod, and the positions of the three detectors are adjusted to be arranged at even intervals, so that the device is more suitable for image detection of "pin-shaped" rabbit cages; the upper rabbit house corresponds to one shooting module, and the lower rabbit cages on both sides correspond to one shooting module respectively, that is, detection of a row of rabbit cages can be completed through one traveling inspection, which greatly improves inspection efficiency.

[0056] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principle and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
