Abstract
Description
Technical Field
[0001] This invention belongs to the field of multispectral imaging technology, specifically relating to the structure of an adjustable multispectral imaging component for monitoring the environment of livestock and poultry houses. Background Technology
[0002] In large-scale, intensive livestock and poultry farming, the environmental conditions within livestock and poultry houses directly impact the health, growth efficiency, and disease control of livestock and poultry. Current methods for monitoring livestock and poultry house environments typically employ point-based sensors or single imaging devices to monitor localized areas. However, these methods often suffer from limited coverage in practice, making it difficult to continuously and comprehensively acquire data on the activity status of livestock and poultry and changes in environmental parameters along the length of the house. When livestock and poultry houses are long, relying solely on fixed-location monitoring equipment can easily lead to blind spots, resulting in incomplete environmental information.
[0003] Meanwhile, to monitor various environmental and physiological parameters such as livestock activity status, harmful gases in the barn, and livestock body surface temperature, existing technologies typically require the deployment of multiple different types of monitoring equipment. It is difficult to maintain consistency in the installation location, sampling time, and monitoring angle of different equipment, easily leading to spatial mismatches or temporal asynchronies. This affects the subsequent comprehensive analysis and judgment of data, reducing the accuracy and reliability of environmental monitoring results.
[0004] Furthermore, when conducting mobile imaging monitoring inside livestock and poultry houses, the monitoring distance constantly changes with the location of the equipment. If the orientation or elevation angle of the imaging equipment cannot be adjusted according to the monitoring location, it can easily lead to a shift in the imaging perspective, affecting the image clarity and the consistency of the imaging area. Especially when multiple imaging devices are working simultaneously, if the attitudes of each imaging device cannot be adjusted synchronously, it may further exacerbate the inconsistency between imaging in different bands. Summary of the Invention
[0005] To address the problems existing in the prior art, the purpose of this invention is to provide an adjustable multispectral imaging component structure for monitoring the environment of livestock and poultry houses. This imaging component structure can uniformly adjust the scanning direction and elevation angle of multiple multispectral imaging devices to achieve consistent acquisition of multispectral information in space and time.
[0006] To achieve the above objectives, the present invention provides the following technical solution: An adjustable multispectral imaging component structure for monitoring the environment of livestock and poultry houses includes a track fixed to the top of the livestock and poultry house. The track has an I-shaped structure, and racks are evenly arranged on both sides of the lower part of the track. A synchronous displacement mechanism is slidably installed at the bottom of the track. The synchronous displacement mechanism moves along the track surface to perform long-distance scanning imaging. A scanning orientation adjustment mechanism is installed at the bottom of the synchronous displacement mechanism. The scanning orientation adjustment mechanism includes a mounting plate placed parallel to the synchronous displacement mechanism below it. A rotating cylinder is installed at the bottom of the mounting plate. The rotating cylinder is hollow inside and open on one side. Side plates are provided on both sides of the open side of the rotating cylinder. Three scanning imagers are rotatably installed between the two side plates. The scanning orientation adjustment mechanism controls the direction of the scanning imager by rotation. The scanning elevation angle synchronous adjustment mechanism is installed inside the rotating cylinder. The scanning elevation angle synchronous adjustment mechanism is used to synchronously control the elevation angle of the three scanning imagers.
[0007] Furthermore, the filter bands of the three scanning imagers are 450-550nm, 1500nm-1600nm, and 8-14μm, respectively, which are used to detect the activity status of livestock and poultry, ammonia concentration, and body temperature of livestock and poultry.
[0008] Furthermore, the scanning elevation angle synchronous adjustment mechanism includes a fixed plate that is bolted to the bottom opening of the rotating cylinder. The fixed plate seals the bottom of the rotating cylinder. A third motor is fixed to the lower surface of the fixed plate. A threaded rod is installed at the output end of the third motor. The threaded rod rotates vertically at the center inside the rotating cylinder.
[0009] Furthermore, each of the three scanning imagers has a fixing rod on its back. The upper surface of the fixing plate has symmetrically arranged columns on the side close to the scanning imager. An internal threaded cylinder is screwed onto the surface of the threaded rod. A control plate is vertically slidably installed between the two columns. Two connecting rods are welded between the control plate and the internal threaded cylinder.
[0010] Furthermore, three joint bearings are evenly installed on the inner side of the control board surface, and the three fixing rods pass through the joint bearings respectively. The elevation angle of the three scanning imagers can be adjusted synchronously by the vertical movement of the control board.
[0011] Furthermore, a worm gear is provided at the center of the top of the rotating cylinder, the worm gear is placed above the mounting plate, upper extension plates are symmetrically fixed on the upper surface of the mounting plate, a worm is rotatably installed between the two upper extension plates, a second motor is fixed on one side of the mounting plate, one end of the worm is installed on the output end of the second motor, and the worm and the worm gear mesh with each other.
[0012] Furthermore, a battery is fixed on one side of the mounting plate and a limit switch is fixed on the other side; Support columns are provided at the four corners of the upper surface of the mounting plate, and the tops of the four support columns are all bolted to the bottom of the slide plate.
[0013] Furthermore, the synchronous displacement mechanism includes a slide plate, on the upper surface of which upright plates are symmetrically arranged. The two upright plates are respectively placed on both sides of the track. A power shaft is rotatably mounted at the center of the surface of the upright plate. A gear is provided on the inner end of the power shaft. The gear is placed inside the track and meshes with the rack.
[0014] Furthermore, the bottom of the skateboard is symmetrically provided with lower extension plates, a first motor is fixed on one side of the lower extension plate, a rotating shaft is installed at the output end of the first motor, the rotating shaft is rotatably positioned between the two lower extension plates, and a transmission belt is installed between the two sides of the rotating shaft and the outer end of the power shaft.
[0015] Compared with the prior art, the beneficial effects of the present invention are: This technical solution achieves continuous scanning imaging along the length of the livestock shed by reciprocating the synchronous displacement mechanism along the track on the top of the shed. This allows the monitoring equipment to cover the entire space inside the shed, structurally solving the problem that fixed monitoring equipment can only collect data from local areas and is prone to creating blind spots. This ensures the completeness and continuity of information acquisition on livestock activity status and the environment inside the shed.
[0016] By setting a scanning orientation adjustment mechanism below the synchronous displacement mechanism and using a rotating cylinder in conjunction with a worm gear transmission structure to adjust the scanning direction of the scanning imager, the scanning imager can switch between scanning the areas on both sides of the livestock and poultry house during movement, avoiding the problem of limited monitoring area caused by imaging in a single direction. At the same time, the self-locking characteristic of the worm gear structure ensures that the scanning direction can be stably maintained after adjustment, thereby improving the stability of the imaging process.
[0017] By setting up multiple scanning imagers and configuring different band filters, multiple scanning imagers can simultaneously collect data on livestock and poultry activity status, ammonia concentration in the barn, and livestock and poultry body temperature at the same time and spatial location. This eliminates the time asynchrony problem caused by time-sharing acquisition by multiple devices from the perspective of structure and operation, ensuring the consistency of multispectral images in time and space, and providing a reliable data foundation for subsequent multi-parameter comprehensive analysis.
[0018] By setting a scanning elevation angle synchronous adjustment mechanism inside the rotating cylinder and using a threaded transmission structure to drive the control plate to move up and down, the elevation angles of multiple scanning imagers can be adjusted synchronously. This ensures that the imaging area and imaging scale of multiple scanning imagers remain consistent even when the monitoring distance changes due to changes in the position of the synchronous displacement mechanism, thus avoiding imaging deviation problems caused by inconsistent elevation angles.
[0019] The control board is connected to the fixed rod of the scanning imager by means of a spherical bearing, which enables the scanning imager to rotate smoothly during the elevation angle adjustment process. This ensures the smoothness and synchronicity of the elevation angle change process and avoids structural interference or imaging jitter caused by rigid connection, thereby further improving the consistency and stability of multispectral imaging.
[0020] By using a single drive source in conjunction with a transmission belt to simultaneously drive the power shafts on both sides, the synchronous displacement mechanism maintains left-right synchronization when moving on the track, ensuring consistent meshing of gears and racks, reducing the risk of offset and jamming during movement, thereby improving the stability and reliability of the overall moving scanning process.

[0023] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention. Example
[0024] See Figure 1-8 An adjustable multispectral imaging component structure for monitoring livestock and poultry house environment includes a track 1 fixed to the top of the livestock and poultry house. The track 1 has an I-shaped structure, and racks 11 are evenly arranged on both sides of the lower part of the track 1. A synchronous displacement mechanism 2 is slidably installed at the bottom of the track 1. When the livestock and poultry house is long and continuous coverage monitoring of the environment inside the house is required, fixed monitoring equipment is prone to forming monitoring blind spots and is difficult to achieve overall scanning coverage. The synchronous displacement mechanism 2, in conjunction with the track 1, can reciprocate along the central axis of the livestock and poultry house, thereby providing a stable moving foundation for multispectral imaging. The I-shaped structure of the track 1 is used to improve the overall load-bearing strength and limit the moving path of the synchronous displacement mechanism 2. The racks 11 are arranged along the length of the track 1 to provide stable meshing drive conditions for the synchronous displacement mechanism 2. The synchronous displacement mechanism 2 achieves linear displacement along the track 1 by cooperating with the racks 11, thereby meeting the needs of long-distance scanning imaging of the livestock and poultry house environment.
[0025] The synchronous displacement mechanism 2 moves along the surface of the track 1 to perform long-distance scanning imaging. A scanning orientation adjustment mechanism 3 is installed at the bottom of the synchronous displacement mechanism 2. The scanning orientation adjustment mechanism 3 includes a mounting plate 31 placed parallel to the bottom of the synchronous displacement mechanism 2. A rotating cylinder 37 is installed at the bottom of the mounting plate 31. The rotating cylinder 37 is hollow inside, with one side open. Side plates 371 are provided on both sides of the open side of the rotating cylinder 37. Three scanning imagers 4 are rotatably mounted between the two side plates 371. In the process of monitoring the environment of livestock and poultry houses, fixed scanning in a single direction easily leads to limited monitoring angles and makes it difficult to achieve simultaneous monitoring. On both sides of the body, a scanning orientation adjustment mechanism 3 is set below the synchronous displacement mechanism 2, which can adjust the scanning direction during the moving scanning process. The mounting plate 31 serves as the supporting base for the scanning orientation adjustment mechanism 3 and is used to connect the synchronous displacement mechanism 2 and the rotating cylinder 37. The rotating cylinder 37 is used to provide rotational installation space for the scanning imager 4 and to limit the overall rotation axis of the scanning imager 4. The side plate 371 is used to limit and support the scanning imager 4, so that the three scanning imagers 4 can rotate synchronously around the same rotation axis, thereby ensuring the consistency of the multispectral scanning direction.
[0026] The scanning orientation adjustment mechanism 3 controls the direction of the scanning imager 4 by rotation. The scanning elevation angle synchronous adjustment mechanism 5 is installed inside the rotating cylinder 37. The scanning elevation angle synchronous adjustment mechanism 5 is used to synchronously control the elevation angle of the three scanning imagers 4. When performing multispectral imaging in livestock and poultry houses, the monitoring distance changes with the position of the synchronous displacement mechanism 2. If the elevation angle of the scanning imager 4 cannot be adjusted, it is easy to cause the imaging area to shift or the imaging clarity to decrease. The scanning elevation angle synchronous adjustment mechanism 5 is set inside the rotating cylinder 37, which can uniformly adjust the elevation angle of the three scanning imagers 4 without affecting the operation of the scanning orientation adjustment mechanism 3, thereby ensuring the consistency of the imaging area and imaging scale when scanning at different positions.
[0027] See Figure 6 The three scanning imagers 4 have filter bands of 450-550nm, 1500nm-1600nm, and 8-14μm, respectively, which are used to detect livestock and poultry activity status, ammonia concentration, and livestock and poultry body temperature. In the monitoring of livestock and poultry house environment, it is necessary to simultaneously acquire livestock and poultry activity information, environmental gas information, and livestock and poultry physiological status information. The spectral characteristics corresponding to different monitoring targets are significantly different. By setting different band filters for the three scanning imagers 4, the three scanning imagers 4 can perform multi-band imaging of the same area at the same time, thereby avoiding the time synchronization problem caused by time-sharing acquisition by multiple devices, and providing a unified data foundation for subsequent multispectral data fusion.
[0028] See Figure 5-8 The scanning elevation angle synchronous adjustment mechanism 5 includes a fixing plate 51 bolted to the bottom opening of the rotating cylinder 37. The fixing plate 51 seals the bottom of the rotating cylinder 37. A third motor 54 is fixed to the lower surface of the fixing plate 51. A threaded rod 52 is installed at the output end of the third motor 54. The threaded rod 52 rotates vertically at the center inside the rotating cylinder 37. When the scanning elevation angle needs to be adjusted, the third motor 54 provides stable rotational power as a drive source. The fixing plate 51 is used to close the bottom of the rotating cylinder 37 and provide a mounting base for the third motor 54. The threaded rod 52 is located at the center inside the rotating cylinder 37 and is used to convert the rotational motion of the third motor 54 into an axial displacement adjustment base, thereby providing power transmission conditions for subsequent elevation angle synchronous adjustment.
[0029] See Figure 5-8Each of the three scanning imagers 4 has a fixed rod 41 on its back. A column 53 is symmetrically arranged on the upper surface of the fixed plate 51 near the scanning imager 4. An internally threaded cylinder 56 is screwed onto the surface of the threaded rod 52. A control plate 55 is vertically slidably installed between the two columns 53. Two connecting rods 57 are welded between the control plate 55 and the internally threaded cylinder 56. During elevation adjustment, the fixed rod 41 connects the scanning imager 4 to the elevation adjustment structure. The column 53 limits the direction of movement of the control plate 55. The internally threaded cylinder 56 is threadedly engaged with the threaded rod 52 to achieve axial displacement conversion. The control plate 55 moves synchronously with the internally threaded cylinder 56 under the drive of the connecting rods 57, thus forming a unified elevation adjustment drive structure.
[0030] See Figure 5-8 Three spherical bearings 58 are evenly installed on the inner side of the control board 55. Three fixed rods 41 pass through the spherical bearings 58 respectively. The elevation angle of the three scanning imagers 4 is adjusted synchronously by the vertical movement of the control board 55. During the elevation angle adjustment, the spherical bearings 58 provide rotational freedom for the fixed rods 41, so that the scanning imagers 4 can smoothly change the tilt angle when the control board 55 moves up and down. The vertical displacement of the control board 55 is synchronously transmitted to the three scanning imagers 4 through the three spherical bearings 58, thereby ensuring the consistency of the three scanning imagers 4 during the elevation angle change process.
[0031] See Figure 1-4 A worm gear 38 is located at the top center of the rotating cylinder 37. The worm gear 38 is positioned above the mounting plate 31. Upper extension plates 35 are symmetrically fixed on the upper surface of the mounting plate 31. A worm 36 is rotatably mounted between the two upper extension plates 35. A second motor 39 is fixed on one side of the mounting plate 31. One end of the worm 36 is mounted on the output end of the second motor 39. The worm 36 meshes with the worm gear 38. When the scanning direction needs to be adjusted, the second motor 39 drives the worm 36 to rotate. The worm 36 drives the rotating cylinder 37 to rotate through meshing with the worm gear 38. The upper extension plates 35 are used to support and limit the worm 36. The worm gear 38 is located at the top center of the rotating cylinder 37 to ensure that the scanning imager 4 rotates around the vertical axis. The worm gear structure has a reverse self-locking characteristic, so that the rotating cylinder 37 can maintain a stable position after the scanning direction is adjusted.
[0032] See Figure 1-4A battery 33 is fixed on one side of the mounting plate 31 and a limit switch 34 is fixed on the other side. Support columns 32 are provided at the four corners of the upper surface of the mounting plate 31, and the tops of the four support columns 32 are all bolted to the bottom of the slide plate 21. During the moving scanning process, in order to avoid the complex wiring caused by frequent external power supply, the battery 33 is used to provide power support for the scanning imager 4 and the drive motor. The limit switch 34 is used to detect the position when the synchronous displacement mechanism 2 moves to the end of the track 1. The support columns 32 are used to form a stable connection structure between the mounting plate 31 and the slide plate 21, thereby ensuring the overall stability of the scanning orientation adjustment mechanism 3 during the movement process.
[0033] See Figure 1-3 The synchronous displacement mechanism 2 includes a slide plate 21. Symmetrical upright plates 22 are arranged on the upper surface of the slide plate 21, with the two upright plates 22 positioned on opposite sides of the track 1. A power shaft 23 is rotatably mounted at the center of the surface of each upright plate 22. A gear 24 is located on the inner end of the power shaft 23, positioned inside the track 1, and meshes with a rack 11. During long-distance scanning, the slide plate 21 supports the scanning orientation adjustment mechanism 3 and the scanning imager 4, while the upright plates 22 support and position the power shaft 23. The power shaft 23 achieves synchronous displacement along the track 1 through the meshing of the gear 24 and the rack 11, thus ensuring the stability and synchronicity of the synchronous displacement mechanism 2 during movement.
[0034] See Figure 1-3 The bottom of the slide plate 21 is symmetrically provided with lower extension plates 25. A first motor 27 is fixed on one side of the lower extension plate 25. A rotating shaft 26 is installed at the output end of the first motor 27. The rotating shaft 26 is rotatably positioned between the two lower extension plates 25. A transmission belt 28 is installed between the two sides of the rotating shaft 26 and the outer end of the power shaft 23. When the synchronous displacement mechanism 2 is driven to move, the first motor 27 serves as the power source to drive the rotating shaft 26 to rotate. The rotating shaft 26 drives the two power shafts 23 to rotate simultaneously through the transmission belt 28, thereby keeping the gear 24 and the rack 11 in a synchronous meshing state, avoiding the synchronous displacement mechanism 2 from deviating or jamming during the movement. Example
[0035] See Figure 1-3 , Figure 7-8 In this embodiment, the track 1 is made of Q235B structural steel. The track 1 is fixed to the main beam at the top of the livestock house by expansion bolts. The racks 11 on both sides of the lower part of the track 1 are made of 40Cr tempered steel to improve wear resistance. The sliding plate 21 in the synchronous displacement mechanism 2 is made of aluminum alloy profile to reduce the overall weight. The upright plate 22 is fixed to the sliding plate 21 by welding. The power shaft 23 is made of 45 steel and is rotatably installed at the center of the surface of the upright plate 22 through the bearing seat. The gear 24 on the inner end of the power shaft 23 is continuously meshed with the rack 11. The first motor 27 is a DC geared motor with a rated power of 120W. The first motor 27 drives the two power shafts 23 to rotate simultaneously through the rotating shaft 26 and the transmission belt 28, so that the synchronous displacement mechanism 2 moves back and forth at a constant speed along the track 1, thereby realizing continuous scanning imaging of the length of the livestock and poultry house, avoiding the problem that fixed monitoring equipment can only monitor local areas.
[0036] Compared with monitoring and imaging equipment that is fixedly installed at a single location on the top of the livestock and poultry house, the middle and rear areas of the livestock and poultry house cannot be effectively covered due to the fixed location of the equipment, and dynamic tracking and monitoring cannot be achieved when the activity area of livestock and poultry changes, resulting in significant gaps in environmental monitoring data.
[0037] Example 3: See Figure 1-4 , Figure 7 In this embodiment, the mounting plate 31 in the scanning orientation adjustment mechanism 3 is made of aluminum alloy sheet with a thickness of 8mm, and the mounting plate 31 is rigidly connected to the sliding plate 21 through the support column 32. The rotating cylinder 37 is made of stainless steel as a whole. The worm wheel 38 set at the top center of the rotating cylinder 37 is made of tin bronze to reduce friction and wear. The worm 36 is made of alloy steel and is supported by the upper extension plate 35. The second motor 39 is a DC geared motor with a rated speed of 30 rpm. It drives the rotating cylinder 37 to rotate through the meshing of the worm 36 and the worm wheel 38, so that the scanning imager 4 inside the rotating cylinder 37 can perform directional scanning on the left and right sides of the livestock house during synchronous displacement. At the same time, the reverse self-locking characteristic of the worm wheel and worm is used to keep the scanning direction stable.
[0038] Compared to imaging equipment installed with a fixed orientation, when the equipment is moved or livestock activities are concentrated on one side of the shed, the other side cannot be effectively imaged, resulting in a limited monitoring area and incomplete image information. Example
[0039] See Figure 5-8 In this embodiment, the three scanning imagers 4 are respectively selected as industrial-grade visible light imaging modules, short-wave infrared imaging modules and long-wave infrared thermal imaging modules, and the outer shell of the scanning imagers 4 is made of die-cast aluminum alloy. The first scanning imager 4 is equipped with a filter with a wavelength of 450-550nm to collect images of livestock and poultry activity status; the second scanning imager 4 is equipped with a filter with a wavelength of 1500nm-1600nm to detect the distribution of ammonia in the barn; and the third scanning imager 4 is equipped with a filter with a wavelength of 8-14μm to collect information on the surface temperature of livestock and poultry. Three scanning imagers 4 are installed and driven through the same synchronous displacement mechanism 2 and scanning orientation adjustment mechanism 3, so that multiple band images are acquired at the same time and in the same spatial position, thereby avoiding the time synchronization problem caused by time-sharing acquisition by multiple devices.
[0040] Compared to using three separate monitoring devices to obtain activity, gas, and body temperature information, the different installation locations and asynchronous sampling times of the devices made it impossible to achieve accurate spatial and temporal alignment during subsequent data analysis. Example
[0041] See Figure 5-8 In this embodiment, the fixing plate 51 in the scanning elevation angle synchronization adjustment mechanism 5 is made of stainless steel and is fixed to the bottom opening of the rotating cylinder 37 with bolts. The third motor 54 is a DC motor with a rated power of 60W. The threaded rod 52 installed at the output end of the third motor 54 adopts a trapezoidal thread structure. The threaded rod 52 and the internal threaded cylinder 56 form a stable threaded transmission pair. The internal threaded cylinder 56 is connected to the control plate 55 via the connecting rod 57. The control plate 55 slides vertically under the limiting action of the column 53, thereby achieving synchronous changes in the elevation angles of the three scanning imagers 4 under the drive of the third motor 54, in order to adapt to the imaging requirements at different monitoring distances.
[0042] Compared to imaging equipment installed at a fixed elevation angle, imaging areas are prone to shift when the equipment position changes, resulting in decreased image clarity and inconsistent monitoring areas. Example
[0043] See Figure 5-8 In this embodiment, three joint bearings 58 are evenly arranged on the inner side of the control board 55. The joint bearings 58 adopt a self-lubricating spherical bearing structure, and the fixing rod 41 adopts a stainless steel round rod and passes through the joint bearings 58. During the up-and-down movement of the control panel 55, the joint bearing 58 allows the fixed rod 41 to change angle, so that the scanning imager 4 can rotate smoothly during the elevation angle adjustment, thereby avoiding structural interference and imaging jitter caused by rigid connection and ensuring attitude consistency during multispectral imaging.
[0044] Compared to using a rigid linkage to directly drive the elevation angle adjustment of the imaging device, which is prone to jamming and shaking during elevation angle changes, affecting image quality and device stability. Example
[0045] See Figure 1-3In this embodiment, the first motor 27 drives the power shafts 23 located on both sides of the slide plate 21 simultaneously through the transmission belt 28. The gears 24 on the power shafts 23 mesh synchronously with the racks 11 in the track 1, so that the synchronous displacement mechanism 2 experiences consistent force on both sides during movement. By using a single power source to achieve dual-side synchronous drive, the synchronous displacement mechanism 2 can be effectively prevented from shifting or tilting when running on track 1, thereby improving the smoothness and reliability of the moving scanning process.
[0046] Compared to mobile structures using a single-sided drive method, these structures are prone to skewness and unstable meshing during operation, and may experience jamming and structural wear after long-term operation.
[0047] The working principle of this invention is as follows: the track 1 is fixed on the central axis of the roof of the livestock and poultry house. When in use, the first motor 27 controls the rotation of the rotating shaft 26, and then the transmission belt 28 simultaneously controls the rotation of the two power shafts 23. The synchronous displacement mechanism 2 moves along the track 1 as a whole through the meshing of the gear 24 and the rack 11 to cope with the large-area environmental monitoring scanning work. Three scanning imagers 4 can simultaneously monitor the activity range of livestock and poultry, the ammonia concentration in the barn, and the body temperature of livestock by scanning different spectral bands. The second motor 39 controls the rotation of the worm gear 36, which in turn controls the rotation of the rotating cylinder 37 through the meshing of the worm gear 36 and the worm wheel 38, thereby controlling the orientation of the scanning imagers 4. The worm gear and worm wheel are fixed in place by reverse self-locking. In use, the scanning orientation adjustment mechanism 3 controls the scanning imagers 4 to monitor and scan to one side. When they move to the rear of the livestock and poultry barn, the limit switch 34 will be impacted. At this time, the synchronous displacement mechanism 2 moves in the opposite direction and controls the rotating cylinder 37 to rotate 180 degrees to monitor the movement on the other side. This structure, which uses three scanning imagers 4 to work synchronously, can eliminate time difference and ensure that the images of all bands are completely synchronized in space and time, thereby improving the accuracy of subsequent data fusion and analysis. The scanning elevation angle synchronous adjustment mechanism 5 is used to synchronously adjust the elevation angle of the scanning imager 4 to ensure the consistency of images when imaging at different distances. The third motor 54 controls the rotation of the threaded rod 52. Since the control plate 55 can only slide vertically along the surface of the column 53, and the control plate 55 and the inner threaded cylinder 56 are connected and fixed by the connecting rod 57, the rotation of the threaded rod 52 can control the inner threaded cylinder 56 to move up and down, thereby driving the control plate 55 to move up and down. The three fixed rods 41 are all installed through the spherical bearing 58. Therefore, when the control plate 55 moves up and down, the elevation angle of the three scanning imagers 4 can be controlled synchronously, thereby ensuring that the elevation angles of the three scanning imagers 4 are consistent, and further ensuring the consistency of imaging.
[0048] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention are implemented according to conventional methods in the art unless otherwise specified or limited.
