[0042] Example 1:

[0043] Existing passive RFID-based electronic ear tags only transmit a fixed number written in the ear tag itself. When it is necessary to collect information on livestock's body temperature and movement status in real time, the current RFID-based electronic ear tags cannot meet the requirements.

[0044] To address the aforementioned problems, this embodiment proposes an electronic ear tag device, such as... Figure 1 As shown, it includes: a communication module, a temperature sensing module, and a motion sensing module. The temperature sensing module and the motion sensing module are respectively connected to the communication module. The temperature sensing module is used to acquire temperature information, the motion sensing module is used to acquire motion information, and the communication module is used to upload the temperature information and the motion information to the corresponding communication host, and the communication host reports the information.

[0045] In practical applications, based on the signal coverage of the communication host, all surrounding livestock will be fitted with the electronic ear tag device. The electronic ear tag device will continuously broadcast data containing relevant information, which the communication host will then acquire. The broadcast data may include livestock body temperature information and livestock movement information, etc., which will not be elaborated upon in this embodiment.

[0046] In one embodiment, the communication module and the communication host are configured together. For example, when the communication module communicates based on Bluetooth, the communication host is configured as a Bluetooth-based communication host and communicates via Bluetooth technology; when the communication module communicates based on Long Range Radio (LORA), the communication host is configured as a LORA scanning module and communicates via LORA technology.

[0047] In this embodiment, communication based on Bluetooth technology is taken as an example.

[0050] Among them, reference Figure 2 and Figure 3 One end of the thermistor is connected to pin 6 on the Bluetooth chip. In practical applications, when the thermistor is placed in contact with livestock, it can change its resistance value according to the livestock's temperature, thereby processing the data in the Bluetooth chip and obtaining the corresponding temperature information.

[0051] In one embodiment, such as Figure 4 As shown, the motion sensing module includes a motion acquisition chip, the output of which is connected to the motion information input of the Bluetooth chip; the motion acquisition chip is model DA217.

The battery then powers all modules in the electronic ear tag device. Other peripheral circuitry of the micro-energy harvesting chip is not described in detail in this embodiment; please refer to its manual for more specific information.

[0056] This invention acquires livestock temperature information through a temperature sensing module and livestock movement information through a motion sensing module. Then, it uploads the livestock temperature and movement information to a communication host through a communication module, and finally, the communication host reports the data. This invention has a simple structure, low cost, and can continuously collect and report livestock body temperature and movement information.

[0057] Meanwhile, with the addition of a micro-energy harvesting chip and a Bluetooth chip, the electronic ear tag device can convert solar energy into corresponding electrical energy to power the battery, thus extending the battery life of the electronic ear tag device. Finally, through low-power Bluetooth technology, it can continuously collect livestock temperature and movement information, enabling real-time monitoring of the livestock's physiological state and achieving true smart grazing.
