Description

Technical Field

[0001] This utility model relates to an animal ear tag, and more particularly to an animal ear tag with a Hall switch circuit that can perform an alarm function after the secondary tag is separated from the primary tag. Background Technology

[0002] Regarding the design of animal ear tags, the styles of animal ear tags developed on the market vary, and animal ear tags with Hall effect switch circuits are relatively rare. According to the applicant's search, the following two prior application documents are mainly: Comparative document 1, patent application number "CN202022926501.6" entitled "An Animal Ear Tag with Automatic Power On / Off Function," belongs to the field of animal ear tag technology and relates to an animal ear tag with automatic power on / off function. A magnetic component slot is located on the upper right of the back cover and a magnetic component is installed thereon. A Hall switch for sensing the magnetic component is installed on the upper right of the PCB board. The magnetic component slot corresponds to the installation position of the Hall switch. The magnetic component slot is a pocket-shaped structure with an upward opening and a sealed bottom. Its exterior is square, and its interior is a semi-circular arc shape equal to half the area of ​​the magnetic component. Its internal thickness is greater than the thickness of the magnetic component. The magnetic component uses a circular magnet. Its structure is simple, easy to operate, and the ear tag is in a power-off state when not in use. It has a long service life, reduces costs, and is environmentally friendly. This patent application mainly focuses on placing the Hall switch on the main tag to realize the power on / off function of the ear tag.

[0003] Comparative document 2, patent application number "CN202022472862.8" entitled "A Bluetooth Eartag Capable of Detecting Internal Temperature," discloses a Bluetooth eartag capable of detecting internal temperature. It includes a housing, within which a main control circuit module and a power supply circuit module are housed. The housing also contains an internal temperature monitoring circuit module, a sleep control circuit module, and a low-power storage circuit module. A magnet is detachably mounted on the outside of the housing at a position corresponding to the Hall switch HR1. The internal temperature monitoring circuit module is connected to the main control circuit module to monitor the internal temperature of the Bluetooth eartag housing. The sleep control circuit module is connected to the main control circuit module to control the Bluetooth chip U1 to enter a low-power sleep state. The low-power storage circuit module is connected to the main control circuit module to store the internal temperature data and Bluetooth received data of the Bluetooth eartag housing. This invention can monitor the internal temperature of the Bluetooth eartag housing, promptly detecting abnormal increases in internal temperature and alerting staff for timely intervention. Furthermore, it can reduce the power consumption of the Bluetooth eartag and improve its battery life.

[0004] In summary, neither of the two comparative documents disclosed the function or structure of using a Hall effect switch to alert animals to whether the main and secondary ear tags have fallen off, thus triggering an alarm. Utility Model Content

[0005] The purpose of this invention is to provide an animal ear tag with a Hall switch circuit that is simple in structure, small in size, low in cost, easy to install, and can promptly alert the user when the main tag and the sub-tag have fallen off.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An animal ear tag with a Hall effect switch circuit includes: a main tag 1 and a secondary tag 2, which are mounted together by an ear stud 3. A magnet 4 is installed inside the secondary tag 2, and a main board 6 is installed inside the main tag 1. The main board 6 includes a Hall effect power supply switch 61, a processing unit 62, a communication antenna 63, a power supply switch 64, and a Hall effect detection unit 5. After detecting a signal, the Hall effect detection unit 5 transmits it to the processing unit 62. The processing unit 62 transmits the processed signal to the communication antenna 63, and the communication antenna 63 transmits the signal to a host computer 8, which pushes an alarm to the user terminal through the background. The battery 7 supplies power to the processing unit 62 and the Hall effect power supply switch 61 through the power supply switch 64. The animal ear tag with Hall switch circuit includes a sub-tag 2 consisting of a sub-tag TPU pad 21 and a sub-tag steel sheet 22. The sub-tag steel sheet 22 is pasted or snapped into the sub-tag TPU pad 21. Together, they form the main structure of the sub-tag 2. The magnet 4 is disposed between the sub-tag TPU pad 21 and the sub-tag steel sheet 22.

[0007] The animal ear tag with Hall switch circuit has a groove 211 on the sub-tag TPU pad 21, and an arc-shaped protrusion 221 on the sub-tag steel sheet 22 at the corresponding position. The magnet 4 is disposed between the groove 211 and the protrusion 221.

[0008] The animal ear tag with Hall effect switch circuit described herein has a magnet 4 in the shape of a square, rectangle, or cylinder, preferably a cylinder.

[0009] The animal ear tag with Hall switch circuit described above includes a main tag 1 comprising an upper main tag shell 11 and a lower main tag shell 12. The upper main tag shell 11 and the lower main tag shell 12 are integrated by means of snap-fit, fastening, or adhesive. The battery 7 is disposed inside the lower main tag shell 12. The Hall detection unit 5, the main board 6, and the battery 7 are disposed inside the lower main tag shell 12.

[0010] The animal ear tag with Hall switch circuit described herein, wherein the Hall detection unit 5 is an all-polar Hall switch, model: MT8633.

[0011] The animal ear tag with Hall effect switch circuit described above, and the user terminal may be a mobile phone, monitor, or tablet device.

[0012] Compared with existing technologies, the advantages of this utility model are as follows: This utility model provides an animal ear tag with a Hall effect switch circuit, mainly applicable to animal ear tags that use a main tag and a secondary tag together. Through the cooperation of the main tag and the secondary tag, a magnet is placed on the secondary tag, and a Hall effect detection unit is placed on the main tag. When the two are fastened together, the Hall effect detection unit outputs a low level. When the main tag and the secondary tag separate, the magnet leaves the Hall effect detection unit, and the Hall effect detection unit outputs a high level, thus triggering an alarm to notify the animal that the ear tag has fallen off. Ranch personnel receive the alarm and immediately take action. This avoids the situation where animal ear tags fall off accidentally or due to human intervention, resulting in lost animals and mitigating economic losses for ranchers. Attached Figure Description
