For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0030] The following is combined with Figures 1 - 5 , and through specific embodiments and their application scenarios, a kind of electronic ear tag provided by the embodiments of the present utility model will be described in detail.

[0031] Such as Figure 1As shown in the figure, the utility model provides an electronic ear tag, which includes: a female tag 1, a male tag 2, a locator, a temperature measuring probe 3, a heart rate sensor 4, a control main board 5 and a wireless communication module 6. As Figure 2 As shown, the female tag 1 has an installation cavity 11. The locator and the wireless communication module 6 are both located in the installation cavity 11. The male tag 2 is provided with a needle 21. The needle 21 is used for puncturing the ear of a livestock and plugging into the female tag 1. The temperature measuring probe 3 and the heart rate sensor 4 are respectively installed on one side of the female tag 1 facing the male tag 2. The locator, the temperature measuring probe 3 and the heart rate sensor 4 are respectively electrically connected to the control main board 5, and the control main board 5 is electrically connected to the wireless communication module 6.

[0032] All the functional elements of the electronic ear tag provided by the utility model are installed on the female tag 1. Specifically, the needle 21 is fixed to the male tag 2. Optionally, the needle 21 and the male tag 2 are of an integral structure. As Figure 1 As shown, the female tag 1 has a through hole 13. During use, the needle 21 is punctured into the ear of the livestock, and the needle 21 is fixedly inserted into the through hole 13, so that the male tag 2 is firmly combined with the female tag 1, and the ear of the livestock is closely attached between the female tag 1 and the male tag 2. Such a sandwich structure design not only ensures the stability of the electronic ear tag, but also reduces the interference and discomfort to the livestock. Among them, since there is less hair on the inner ear side of the livestock, the female tag 1 can be fixed on the inner ear side of the livestock, so that the temperature measuring probe 3 and the heart rate sensor 4 can fit better with the ear of the livestock, thereby improving the accuracy of various data monitoring. At the same time, the ear of the livestock can also play a certain role in protecting the female tag 1.

[0033] It can be understood that the control main board 5 can be a controller with processing functions well-known in the technical field. The locator is used to detect the position information of the livestock in real time. The locator sends the position information of the livestock to the control main board 5, and the control main board 5 transmits the position information of the livestock to the livestock management terminal in real time through the wireless communication module 6, so that the breeding personnel can monitor the movement positioning of the livestock in real time.

[0034] The temperature measuring probe 3 is used to detect the body temperature of the livestock. In traditional electronic ear tags, the temperature sensor is installed inside the electronic ear tag, and there is a housing between the temperature sensor and the ear of the livestock, resulting in the temperature value detected by the temperature sensor being easily affected by factors such as the thermal conductivity of the housing material, air temperature, and fitting tightness, causing detection errors. The utility model is provided with a first installation hole 17 and a second installation hole 18 on one side of the female tag 1 close to the male tag 2. As Figure 3 As shown, the temperature measuring probe 3 is plugged into the first installation hole 17, and the acquisition end of the temperature measuring probe 3 is flush with one side of the female tag 1 facing the male tag 2, so that the temperature measuring probe 3 can directly contact the ear of the livestock, avoiding interference from other factors, and ensuring the accuracy of the temperature measuring probe 3 for detecting the body temperature of the livestock.

[0035] Similarly, as Figure 3As shown, the heart rate sensor 4 is plugged into the second mounting hole 18, and the conduction surface of the heart rate sensor 4 is flush with the side of the female label 1 facing the male label 2, so that the heart rate sensor 4 can be directly attached to the ear of the livestock, thereby effectively monitoring the heart rate of the livestock in real time.

[0036] The utility model provides an electronic ear tag. The needle 21 penetrates the ear of the livestock and is plugged into the female label 1, so that the ear of the livestock is clamped between the male label 2 and the female label 1. The temperature measurement probe 3 and the heart rate sensor 4 are respectively installed on the side of the female label 1 facing the male label 2, so that the temperature measurement probe 3 and the heart rate sensor 4 are in direct and close contact with the ear of the livestock, thereby ensuring the accuracy of monitoring the body temperature and heart rate of the livestock; the locator is used to monitor the position information of the livestock in real time. The locator, the temperature measurement probe 3 and the heart rate sensor 4 are respectively electrically connected to the control main board 5, and the control main board 5 is electrically connected to the wireless communication module 6. The control main board 5 sends the position information, body temperature information and heart rate information of the livestock to the livestock management terminal in real time through the wireless communication module 6, so that the breeding personnel can obtain the health status of the livestock from multiple dimensions. The electronic ear tag provided by the utility model has rich functions and can perform multi-dimensional health monitoring on livestock, meeting the high requirements of modern animal husbandry for livestock health management.

[0037] Furthermore, the electronic ear tag further includes a triaxial accelerometer. The triaxial accelerometer is fixedly installed in the installation cavity 11, and the triaxial accelerometer is electrically connected to the control main board 5.

[0038] The triaxial accelerometer is used to accurately measure the motion acceleration of the livestock. By capturing the acceleration data in the three axes of X, Y, and Z, the motion conditions of the livestock in different directions can be detected. The control main board 5 sends the acceleration data detected by the triaxial accelerometer to the livestock management terminal through the wireless communication module 6, so that the livestock management terminal can analyze the behavior patterns of the livestock in detail, including various activity states such as gait, standing, lying, running, etc.

[0039] And / or, the electronic ear tag further includes a gyroscope. The gyroscope is fixedly installed in the installation cavity 11, and the gyroscope is electrically connected to the control main board 5. The gyroscope is used to measure and record the angular velocity of the livestock. By capturing the angular velocity data in the three axes of X, Y, and Z, the motion and posture changes of the livestock in different directions can be detected. The control main board 5 sends the angular velocity data monitored by the gyroscope to the livestock management terminal through the wireless communication module 6, so that the livestock management terminal can analyze the behavior patterns of the livestock in detail, including various activity states such as gait, standing, lying, turning, etc.

[0040] And / or, the electronic ear tag further includes a three-axis geomagnetic sensor. The three-axis geomagnetic sensor is fixedly installed in the installation cavity 11, and is electrically connected to the control main board 5. The three-axis geomagnetic sensor captures the X, Y, and Z axial data of the geomagnetic field to detect the orientation and movement direction of the livestock. The control main board 5 sends the orientation and movement direction information detected by the three-axis geomagnetic sensor to the livestock management terminal through the wireless communication module 6, which can help the livestock management terminal analyze the walking trajectory and movement path of the livestock in detail, and draw a detailed activity route map, which is of great significance for monitoring the grazing range, behavior patterns and daily activities of the livestock.

[0041] In a specific embodiment, a three-axis accelerometer, a gyroscope and a three-axis geomagnetic sensor are installed in the installation cavity 11 at the same time. The livestock management terminal can combine the multi-dimensional motion data provided by the electronic ear tag to help the breeder take timely measures to ensure the health and safety of the livestock.

[0042] Optionally, the locator is a BLE (Bluetooth Low Energy) module. The BLE module is installed in the installation cavity 11. The BLE module can accurately locate the livestock indoors or outdoors through the strength of the Bluetooth signal (RSSI) or the triangulation positioning technology using multiple BLE beacons, which is convenient for the breeding personnel to track the location of the livestock.

[0043] Optionally, the temperature measurement probe 3 is an NTC temperature sensor. Among them, the NTC temperature sensor can quickly and accurately capture the fluctuation of the body surface temperature of the livestock, improving the accuracy of the electronic ear tag for measuring the body temperature of the livestock.

[0044] Optionally, the heart rate sensor 4 is a photoplethysmogram heart rate sensor. The photoplethysmogram heart rate sensor uses optical technology to calculate the heart rate by measuring the changes in the blood flow of the livestock, and can accurately capture the fluctuations of the heart rate, which is of great significance for the livestock management terminal to study the stress status and early diseases of the livestock.

[0045] Specifically, as Figure 1 shown, a power supply 7 is installed in the installation cavity 11. A charging interface is provided on the outer wall of the female tag 1. The charging interface is electrically connected to the power supply 7. The power supply 7 is respectively electrically connected to the BLE module, the temperature measurement probe 3, the heart rate sensor 4, the control main board 5 and the wireless communication module 6 to supply power to the above functional components at the same time to ensure the normal operation of each functional component.

[0046] The power supply 7 is a rechargeable battery. Optionally, the charging interface can be a USB port, a Type-C port or a Light interface, etc. The charging interface is electrically connected to the rechargeable battery so as to connect an external power supply 7 through the charging interface to charge the rechargeable battery.

[0047] In a specific embodiment, the power source 7 is a lithium polymer battery. The lithium polymer battery has the advantages of light weight, large capacity, high energy density, good durability and high safety, and is suitable for being used as the power source 7 of the electronic ear tag, avoiding the trouble of frequent battery replacement.

[0048] like Figure 1 and Figure 4 As shown, the electronic ear tag also includes a warning light 8. A notch 12 is provided on the side of the mother tag 1. The warning light 8 is plugged into the notch 12.

[0049] Specifically, the warning light 8 is used to indicate the operating status of the electronic ear tag and the abnormal situation of the livestock. Optionally, the notch 12 is provided on the outer side of the mother tag 1 to facilitate the breeding staff to observe the status of the warning light 8. Optionally, in order to ensure the conspicuousness of the warning light 8, the warning light 8 can be an LED strip light.

[0050] The warning light 8 is electrically connected to the control mainboard 5 and the power supply 7, respectively. When the power of the power supply 7 is too low, the control mainboard 5 controls the warning light 8 to continuously light up in red to remind the breeder to charge the power supply 7. In addition, when the livestock has too high body temperature, abnormal heart rate, abnormal heart rate, abnormal positioning or abnormal behavior, the control mainboard 5 controls the warning light 8 to flash red at intervals to remind the breeder to respond to the abnormal state of the livestock in time.

[0051] Optionally, the mother label 1 is a polyurethane mother label and / or the public label 2 is a polyurethane public label. The polyurethane mother label and / or the polyurethane public label are made of polyurethane material, which has anti-aging and corrosion resistance properties, can effectively physically protect the functional components of the electronic ear label, and can be immersed in disinfectant for repeated disinfection and cleaning.

[0052] Optionally, the needle 21 is a copper needle, so that when marking livestock, the needle 21 has a strong puncture strength to ensure that the marking puncture is successful once. At the same time, the copper needle can protect the ears of livestock, prevent livestock ears from infection and suppuration, and indirectly improve the welfare level of livestock.

[0053] like Figure 5 As shown, the electronic ear tag also includes an elastic tube 9. The elastic tube 9 is fixed to the side of the female tag 1 facing away from the male tag 2. The female tag 1 has a through hole 13 connected to the inside of the elastic tube 9. The needle 21 has a needle cap 211. The needle 21 passes through the through hole 13 and the inside of the elastic tube 9 in sequence, and the needle cap 211 is set against the end of the elastic tube 9.

[0054] Optionally, the elastic cylinder 9 and the female label 1 are of an integral structure. The elastic cylinder 9 has a certain elasticity so that when the needle cap 211 passes through the elastic cylinder 9, the elastic cylinder 9 can expand adaptively. When marking, the needle 21 is punctured into the ear of the livestock and successively passes through the inside of the female label 1 and the elastic cylinder 9. The elastic cylinder 9 expands under the extrusion of the needle cap 211. After the needle cap 211 passes through the elastic cylinder 9, the elastic cylinder 9 automatically contracts, and the end of the needle cap 211 and the elastic cylinder 9 away from the female label 1 abuts, thereby ensuring the stability of the connection between the female label 1 and the male label 2 and preventing the electronic ear tag from falling off the ear of the livestock. Optionally, the elastic cylinder 9 is a polyurethane cylinder.

[0055] In some embodiments, as Figure 1 shown, the wireless communication module 6 is an antenna circuit board. The antenna circuit board is provided with a plurality of card slots 61. The plurality of card slots 61 are spaced apart circumferentially along the antenna circuit board. The wall of the installation cavity 11 is provided with a plurality of limiting posts 14 spaced apart circumferentially along it, and the plurality of limiting posts 14 are respectively clamped in the plurality of card slots 61.

[0056] It can be understood that the antenna circuit board refers to an antenna structure in which the antenna 62 is designed and integrated onto a printed circuit board. The antenna circuit board is electrically connected to the control main board 5 and can send the data information detected by the locator, the heart rate sensor 4, and the temperature measurement probe 3 to the mobile terminal. Optionally, the limiting post 14 can be a convex block protruding from the wall of the installation cavity 11, and the convex block extends along the thickness direction of the female label 1. During assembly, by respectively clamping the plurality of limiting posts 14 in the plurality of card slots 61, the antenna circuit board can be firmly fixed in the installation cavity 11 to prevent the antenna circuit board from shaking, thereby ensuring stable communication of the electronic ear tag during use. The control main board 5 and the power supply 7 can be installed in the space between the antenna circuit board and the bottom of the installation cavity 11 to ensure the rationality of the layout of each functional component and the compactness of the structure.

[0057] As Figure 2 shown, the female label 1 includes a base 15 and a cover 16. The cover 16 is hermetically covered on the base 15 to form an installation cavity 11. Each functional component is installed on the base 15. After all the functional components are installed, the cover 16 and the base 15 can be ultrasonically welded to ensure the sealing of the female label 1.

[0058] As Figure 1 shown, the limiting posts 14 are provided on the base 15. One side of the antenna circuit board where the antenna 62 is embedded is coated with conductive adhesive, and the antenna circuit board is adhered to the inner wall of the cover 16 through the conductive adhesive so that the antenna 62 is closely attached to the inner wall of the cover 16, thereby enhancing the emission ability of the antenna 62 to wireless signals.

[0059] As Figure 5 shown, a plurality of marks 161 are etched on the outer wall of the cover 16. The plurality of marks 161 are spaced apart circumferentially along the cover 16.

[0060] Among them, the laser etching method can be used to etch various information that needs to be marked on the cover body 16, such as the breeding farm number, individual number, breed, date of birth, and vaccination status of livestock, so as to carry out unified management of livestock, facilitate the rapid identification of livestock individuals by management personnel, and improve the convenience of using electronic ear tags.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
