Description

An adaptive tension wearable monitoring device for poultry and livestock Technical Field

[0001] The present invention relates to the field of intelligent perception of poultry information, and in particular to an adaptive tension wearable monitoring device applied to poultry and livestock. Background Art

[0002] With the continued development of science and technology, intelligent, information-based, and refined farming are the trend and direction of development in the poultry farming industry. In large-scale farming, some livestock can be equipped with smart monitoring devices to assist in obtaining group information. Compared to manual monitoring, wireless smart monitoring devices offer advantages such as small size, high accuracy, and low stress.

[0003] By monitoring the body temperature, skin electricity and other physical information of poultry and livestock, it is an important indicator of their health status. Timely detection of abnormalities in body temperature, skin electricity and other physical information of poultry and livestock is of great significance for reducing the amount of medicine used in farms, preventing large-scale disease outbreaks, and tracing the quality and health indicator data of poultry and livestock related products throughout the process. As for the body temperature information of poultry and livestock, the vast majority of current breeding and production practices use manual measurement of the cloaca temperature of poultry and livestock as the core body temperature, and the measurement process has a great stress effect on the poultry and livestock herd. The Chinese invention patent document with the prior art publication number: CN112914518A proposes that there is a large correlation between the underwing body temperature and the core body temperature, and the ratio of the underwing axillary area to the cloaca temperature is about 0.983. Therefore, the health of chickens can be monitored by measuring the axillary temperature.

[0004] For chickens, current body temperature monitoring technologies mostly use thermal imaging cameras, such as those in Chinese patents CN114115403A and CN112005931A. While non-contact temperature measurement has minimal stress, it suffers from low accuracy and high actual cost, resulting in limited success in actual production. Direct-contact temperature monitoring technologies, such as those in CN114970755A and CN115219050A, use sensors that come into direct contact with the skin under the wings. While highly accurate and providing valuable data, they are difficult to wear on chickens for extended periods of time and lack specialized wearable structural designs for chickens. This leads to significant stress and poor performance, especially for fast-growing white-feathered broilers, which account for the largest market share. As their size rapidly increases, wearability and temperature measurement stability become difficult to maintain. Therefore, designing a convenient, wearable monitoring device for various physical indicators of poultry and livestock is crucial. Summary of the Invention

[0005] To address the issues raised in the background art, the present invention provides an adaptive tensioning wearable monitoring device for livestock. The device's adaptive tensioning module adjusts the device's size as the livestock grows, resolving the challenge of livestock wearing wearable devices for extended periods of time during production. This improves the stability and accuracy of monitoring various livestock indicators.

[0014] The material of the bionic octopus suction cup array is silicone, and when the flexible ring belt is tightened, a pressing force is generated on the bionic octopus suction cup array to cause the array to deform.

[0015] The bionic octopus suction cup array is a columnar concave cavity formed by combining a cylindrical hole array mold and a metal ball.

[0028] The present invention will be further described below with reference to the accompanying drawings and examples.

[0029] The embodiments of the present invention are as follows: Example 1:

[0030] In this embodiment, the monitoring device of the present invention monitors the body temperature of chickens among poultry:

[0031] As shown in Figure 1, the device includes an adaptive tensioning module 1, a wireless sensor module 6, a flexible endless belt 13 and a monitoring module; the flexible endless belt 13 is arranged inside the adaptive tensioning module 1 and the monitoring module and is connected end to end inside the adaptive tensioning module 1. The surface of the monitoring module is equipped with a wireless sensor module 6, which is an electronic device. The monitoring module and the flexible endless belt 13 are slidingly connected. One end of the adaptive tensioning module 1 is fixedly connected to the fixed end 2 of the flexible endless belt 13, and the other end of the adaptive tensioning module 1 is telescopically connected to the movable end 12 of the flexible endless belt 13. The movable end 12 can be freely retracted and retracted under the action of the tensioner 10 inside the adaptive tensioning module 1. When the flexible endless belt 13 is tightened, the wireless sensor module 6 and the skin at the chicken wing are tightly fitted; the material of the flexible endless belt 13 is flexible and skin-friendly nylon, which is inelastic and non-stretchable, and has less irritation to the skin.

[0032] The adaptive tensioning module 1 includes a tensioner 10, a rotating core 20 and a spring 23;

[0033] As shown in Figure 4, a cylindrical cavity 17 is provided inside the tensioner 10, and a cylindrical shaft 19 is provided along the axial direction of the cylindrical cavity 17. The two end faces of the cylindrical shaft 19 are respectively fitted to the inner wall of the tensioner 10, and a spring 23 is installed at one end of the cylindrical shaft 19. The other end of the cylindrical shaft 19 passes through the central through hole opened by the rotating core 20 which is sleeved on the cylindrical shaft 19. The outer circumferential surface of the rotating core 20 is provided with a first groove 21 and an annular groove 22. The cylindrical shaft 19 is provided with a cylindrical cavity 18 in the vertical direction. The inner end of the spring 23 is fixed in the cylindrical cavity 18, and the outer end of the spring 23 is fixed in the first groove 21 opened on the outer circumferential surface of the rotating core 20. The diameter of the cylindrical cavity 17 is larger than the outer diameter of the rotating core 20, and the diameter of the cylindrical shaft 19 is smaller than the diameter of the central through hole opened by the rotating core 20.

[0034] It also includes a soft conformable pad 3, which is an arc-shaped plate structure. The tensioner 10 and the soft conformable pad 3 are an integrated structure. The outer arc surface of the soft conformable pad 3 is fitted with the inner arc surface of the tensioner 10. The tensioner 10 is wrapped by the soft conformable pad 3. The soft conformable pad 3 extends axially and fits on the back of the chicken, and is dustproof and waterproof.

[0035] A through hole 11 is respectively formed at both ends of the tensioner 10 . The fixed end 2 of the flexible endless belt 13 passes through the through hole 11 at one end of the tensioner 10 and enters the interior of the tensioner 10 and is fixed inside the tensioner 10 .

[0036] The movable end 12 of the flexible annular belt 13 passes through the through hole 11 at the other end of the tensioner 10 and penetrates into the interior of the tensioner 10, and surrounds the outer circumference of the rotating core 20 and is fixedly embedded in the annular belt slot 22. The movable end 12 can rotate back or extend as the rotating core 20 rotates. The rotating core 20 is connected to the tensioner 10 through a spring 23 of appropriate hardness. As the chicken's chest circumference grows, the flexible annular belt 13 extends, and the rotating core 20 rotates clockwise to store energy in the spring 23, which has a tensioning force that counteracts it, so that the soft fitting pad 3 fits tightly to the chicken's back. The curvature of the fitting part imitates the contour curve of the chicken's back, which is similar to the physiological contour line of the back, which can ensure that long-term compression of the chicken's back skin causes less discomfort.

[0037] The clockwork spring 23 in the adaptive tensioning module 1 is a constant-force coil spring. The stress generated during normal deformation remains substantially constant. The spring hardness is selected to ensure firm tension without damaging the skin.

[0038] The fixed end 2 and the movable end 12 of the flexible ring belt 13 are respectively provided with a fixing buckle. The fixed end 2 of the flexible ring belt 13 is hooked on the fixed column 24 provided inside the tensioner 10 through the fixing buckle, and the movable end 12 of the flexible ring belt 13 is embedded in the ring belt slot 22 through the fixing buckle.

[0039] As shown in Figure 2, the monitoring module includes a connecting module 5 and a patch 4; an annular belt perforation 9 is respectively opened at both ends of the connecting module 5, and a flexible annular belt 13 is passed through the annular belt perforation 9. The surfaces of the flexible annular belts 13 on both sides of the connecting module 5 are provided with limiting protrusions 14. The patch 4 is fixed to one end surface of the connecting module 5 close to the skin of the chicken wing. The surface of the patch 4 is provided with a bionic octopus suction cup array 8. The material of the bionic octopus suction cup array 8 is a two-component silicone rubber with moderate hardness, which has certain flexibility and conformality. The physical adhesion effect generated by the bionic octopus suction cup array 8 can make the monitoring site fit more closely and the monitoring results more accurate compared to the flat surface; the bionic octopus suction cup array 8 is prepared using a special mold and is pressed against the skin surface under the tension generated by the tensioner 10, squeezing out the air in the suction cup cavity. The negative pressure effect enhances the stable fit and friction with the skin, avoiding the phenomenon that the monitoring point floats in the air or detaches from the skin surface due to disturbances caused by the chicken's movement, flapping, pecking feathers, etc. during the monitoring period.

[0040] The connecting module 5 that cooperates with the flexible ring belt 13 is encapsulated in a lightweight hard shell. As the chicken's chest circumference increases, the flexible ring belt 13 stretches. Since a limiting protrusion 14 is set in the area where the flexible ring belt 13 slides with the connecting module 5, the limiting protrusion 14 is slightly raised above the plane of the flexible ring belt 13, limiting the connecting module 5 from exceeding the optimal range of sliding adjustment.

[0041] As shown in FIG3 , a circular groove is formed on the surface of the patch 4 , and a wireless sensor module 6 is installed in the groove.

[0042] The wireless sensor module 6 includes a sensor chip layer 7, an antenna layer 15, a power supply layer 16, and a flexible FPC circuit 18. The wireless sensor module 6 is sequentially configured to include the sensor chip layer 7, power supply layer 16, and antenna layer 15. The antenna layer 15 is bonded to the bottom surface of the circular groove, and the flexible FPC circuit 18 connects the sensor chip layer 7 and antenna layer 15, respectively. The patch 4 is applied to the hairless skin area under the armpit of the chicken's wing. The attached bionic suction cup array 8 generates physical adhesion under tension, firmly adhering the patch 4 to the skin surface. The sensor chip layer 7 and the skin of the chicken's wing are in close contact. The wireless sensor module 6 monitors the skin temperature of the chicken's wing at a constant frequency and transmits the information wirelessly to a host computer, thus achieving temperature measurement. As the chicken grows, its chest circumference gradually expands. As the chest circumference increases, the reserved loop wrapped around the rotating core 20 of the movable end 12 is gradually pulled out to achieve adaptive chest circumference adjustment. The patch 4 is installed on one side of the fixed end 2 of the ring belt, and its relative position is relatively stable, and is less affected by the increase in the overall length of the ring belt, which is conducive to stable temperature measurement.

[0043] During the chicken's daily movements, flapping, feather pecking, etc., the patch 4 is in sliding connection with the flexible ring belt 13. The sliding of the patch 4 on the ring belt can buffer the disturbance along the direction of the ring belt and maintain a stable contact between the sensor chip layer 7 and the skin.

[0044] Since the temperature ratio of the armpit area under the wing of poultry to the cloaca is approximately 0.983, in this embodiment, the wireless sensor module 6 is an electronic device for temperature measurement, and the target is white-feathered broiler chickens. The wireless sensor module 6 monitors the skin temperature (i.e., body temperature) of the armpit area under the wing of the white-feathered broiler chickens at a certain frequency. The device is worn about one week after the white-feathered broiler chickens are vaccinated and can be worn for a long time until they are marketed. During this period, no manual loosening or adjustment is required. The body temperature data will be transmitted wirelessly to the host computer and the cloud. As shown in Figure 5, the monitoring device is used to continuously monitor the body temperature of white-feathered broilers for 4 days. The body temperature data is uploaded every 30 minutes through the wireless sensor module 6. Abnormalities in the physical information of the body temperature of poultry and livestock can be discovered in time, which is of great significance for reducing the amount of medicine used in farms, preventing large-scale disease outbreaks, and tracing the quality and health indicator data of poultry and livestock related products throughout the process. It can be seen that the present invention uses a more accurate monitoring method of direct contact with the skin in the armpit area of ​​poultry and livestock, and uses a specially designed wearable structure, as well as an innovatively designed tensioning structure that is adaptive to the chest size and a stable patch structure, which solves the difficulties in the current application of wearable monitoring technology in the field of poultry farming. Example 2:

[0045] In this embodiment, the monitoring device of the present invention performs skin electrical monitoring on cattle among livestock:

[0046] As shown in Figure 1, the device includes an adaptive tensioning module 1, a wireless sensor module 6, a flexible ring belt 13 and a monitoring module; the flexible ring belt 13 is passed through the adaptive tensioning module 1 and the monitoring module and is connected end to end inside the adaptive tensioning module 1. The surface of the monitoring module is equipped with a wireless sensor module 6, which is an electronic device. The monitoring module and the flexible ring belt 13 are slidingly connected. One end of the adaptive tensioning module 1 is fixedly connected to the fixed end 2 of the flexible ring belt 13, and the other end of the adaptive tensioning module 1 is telescopically connected to the movable end 12 of the flexible ring belt 13. The movable end 12 can be freely extended and retracted under the action of the tensioner 10 inside the adaptive tensioning module 1. When the flexible ring belt 13 is tightened, the wireless sensor module 6 fits tightly against the skin at the cow's chest; the material of the flexible ring belt 13 is flexible and skin-friendly nylon, which is inelastic and non-stretchable, and has less irritation to the skin.

[0047] The adaptive tensioning module 1 includes a tensioner 10 , a rotating core 20 and a spring 23 .

[0048] As shown in Figure 4, a cylindrical cavity 17 is provided inside the tensioner 10, and a cylindrical shaft 19 is provided along the axial direction of the cylindrical cavity 17. The two end faces of the cylindrical shaft 19 are respectively fitted to the inner wall of the tensioner 10, and a spring 23 is installed at one end of the cylindrical shaft 19. The other end of the cylindrical shaft 19 passes through the central through hole opened by the rotating core 20 which is sleeved on the cylindrical shaft 19. The outer circumferential surface of the rotating core 20 is provided with a first groove 21 and an annular groove 22. The cylindrical shaft 19 is provided with a cylindrical cavity 18 in the vertical direction. The inner end of the spring 23 is fixed in the cylindrical cavity 18, and the outer end of the spring 23 is fixed in the first groove 21 opened on the outer circumferential surface of the rotating core 20. The diameter of the cylindrical cavity 17 is larger than the outer diameter of the rotating core 20, and the diameter of the cylindrical shaft 19 is smaller than the diameter of the central through hole opened by the rotating core 20.

[0049] It also includes a soft conformable pad 3, which is an arc-shaped plate structure. The tensioner 10 and the soft conformable pad 3 are an integrated structure. The outer arc surface of the soft conformable pad 3 is fitted with the inner arc surface of the tensioner 10. The tensioner 10 is wrapped by the soft conformable pad 3. The soft conformable pad 3 extends axially and fits on the cow's back, and is dustproof and waterproof.

[0050] A through hole 11 is respectively formed at both ends of the tensioner 10 . The fixed end 2 of the flexible endless belt 13 passes through the through hole 11 at one end of the tensioner 10 and enters the interior of the tensioner 10 and is fixed inside the tensioner 10 .

[0051] The movable end 12 of the flexible annular belt 13 passes through the through hole 11 at the other end of the tensioner 10 and penetrates into the interior of the tensioner 10, and surrounds the outer circumference of the rotating core 20 and is fixedly embedded in the annular belt slot 22. The movable end 12 can rotate back or extend as the rotating core 20 rotates. The rotating core 20 is connected to the tensioner 10 through a spring 23 of appropriate hardness. As the cow's chest circumference grows, the flexible annular belt 13 extends, and the rotating core 20 rotates clockwise to store energy in the spring 23, which has a tensioning force that counteracts it, so that the soft fitting pad 3 fits tightly to the cow's back. The curvature of the fitting part imitates the contour curve of the cow's back, which is similar to the physiological contour line of the back, which can ensure that long-term compression of the cow's back skin will cause less discomfort.

[0052] The clockwork spring 23 in the adaptive tensioning module 1 is a constant-force coil spring. The stress generated during normal deformation remains substantially constant. The spring hardness is selected to ensure firm tension without damaging the skin.

[0053] The fixed end 2 and the movable end 12 of the flexible ring belt 13 are respectively provided with a fixing buckle. The fixed end 2 of the flexible ring belt 13 is hooked on the fixed column 24 provided inside the tensioner 10 through the fixing buckle, and the movable end 12 of the flexible ring belt 13 is embedded in the ring belt slot 22 through the fixing buckle.

[0054] As shown in Figure 2, the monitoring module includes a connecting module 5 and a patch 4; an annular belt through-hole 9 is respectively opened at both ends of the connecting module 5, and a flexible annular belt 13 is passed through the annular belt through-hole 9. The surfaces of the flexible annular belts 13 on both sides of the connecting module 5 are provided with limiting protrusions 14. The patch 4 is fixed to one end surface of the connecting module 5 close to the skin of the cow's chest. The surface of the patch 4 is provided with a bionic octopus suction cup array 8. The material of the bionic octopus suction cup array 8 is a two-component silicone rubber with moderate hardness, which has certain flexibility and conformality. The physical adhesion effect generated by the bionic octopus suction cup array 8 can make the monitoring site fit more closely and the monitoring results more accurate compared to the flat surface; the bionic octopus suction cup array 8 is prepared using a special mold and is pressed against the skin surface under the tension generated by the tensioner 10, squeezing out the air in the suction cup cavity. The negative pressure effect enhances the stable fit and friction with the skin, avoiding the phenomenon of the monitoring point floating or detaching from the skin surface due to disturbances caused by the cow's large-scale movement during the skin electrical monitoring of the cow.

[0055] The connecting module 5 that cooperates with the flexible ring belt 13 is encapsulated in a lightweight hard shell. As the cow's chest circumference increases, the flexible ring belt 13 stretches. Since a limiting protrusion 14 is set in the area where the flexible ring belt 13 slides with the connecting module 5, the limiting protrusion 14 is slightly raised above the plane of the flexible ring belt 13, limiting the connecting module 5 from exceeding the optimal range of sliding adjustment.

[0056] As shown in FIG3 , a circular groove is formed on the surface of the patch 4 , and a wireless sensor module 6 is installed in the groove.

[0057] The wireless sensor module 6 includes a sensor chip layer 7, an antenna layer 15, a power supply layer 16, and a flexible FPC circuit 18. The wireless sensor module 6 is sequentially configured with the sensor chip layer 7, power supply layer 16, and antenna layer 15. The antenna layer 15 is in contact with the bottom surface of the circular groove, and the flexible FPC circuit 18 connects the sensor chip layer 7 and antenna layer 15, respectively. The patch 4 is applied to the skin area on the cow's chest. The attached bionic suction cup array 8 generates physical adhesion under tension, keeping the patch 4 firmly attached to the skin surface. The sensor chip layer 7 and the cow's chest skin are in close contact. The wireless sensor module 6 monitors the cow's skin electrical signals at a certain frequency and transmits them wirelessly to a host computer, thus realizing skin electrical monitoring. As the cow grows, its chest circumference gradually expands. As the movable end 12 increases in size, the reserved loop wrapped around the rotating core 20 is gradually pulled out to achieve adaptive chest circumference. The patch 4 is installed on one side of the fixed end 2 of the ring belt, and its relative position is relatively stable, and is less affected by the increase in the overall length of the ring belt, which is conducive to stable skin electricity monitoring.

[0058] During the cow's daily movements, the patch 4 is in sliding connection with the flexible ring belt 13. The sliding of the patch 4 on the ring belt can buffer the disturbance along the ring belt direction and maintain the stable contact between the sensor chip layer 7 and the skin.

[0059] Galvanic skin response is the fluctuation of skin resistance caused by changes in sweat gland activity or the sympathetic nervous system. When cattle and other livestock are stimulated by sensory stimulation or have emotional changes, the blood vessels in the skin will contract and dilate. At the same time, the secretion of sweat glands will also change, causing changes in skin resistance, forming a galvanic skin response. Therefore, in this embodiment, the wireless sensor module 6 is an electronic device for monitoring galvanic skin response. The target of action is cattle among livestock. The wireless sensor module 6 monitors the skin electrical signals of cattle at a certain frequency for a long time, and then transmits them wirelessly to the host computer and the cloud. By monitoring the data, abnormalities in the body information of the skin electrical signals of poultry and livestock can be discovered in a timely manner, which is of great significance for reducing the amount of drugs used in farms, preventing large-scale epidemics, and tracing the quality and health indicator data of poultry and livestock related products.

[0060] It can be seen that the present invention uses a more accurate monitoring method that directly contacts the skin of poultry and livestock, and uses a specially designed wearable structure, as well as an innovatively designed tensioning structure that is adaptive to the chest size and a stable patch structure, which solves the difficulties in the current application of wearable monitoring technology in the breeding field.
