[0045] Example 1:

[0046] To address the problem in existing technologies where the battery in the positioning and data acquisition collar needs to be manually replaced after it runs out of power, Embodiment 1 of this utility model provides a solar-powered data acquisition and positioning device, such as... Figure 1 As shown, it includes: a micro-energy harvesting circuit, a communication circuit, a scanning circuit, a positioning circuit, and a processing circuit; the micro-energy harvesting circuit is connected to a battery, and the battery is connected to the communication circuit, the scanning circuit, the positioning circuit, and the processing circuit respectively; the communication circuit, the scanning circuit, and the positioning circuit are respectively connected to the processing circuit; the micro-energy harvesting circuit is used to harvest solar energy and convert it into electrical energy to charge the battery, and the battery is used to power the communication circuit, the scanning circuit, the positioning circuit, and the processing circuit; the scanning circuit is used to scan the broadcast data of the surrounding matching node collars; the positioning circuit is used to receive the coordinate data of the positioning satellite; the processing circuit is used to send the received broadcast data and coordinate data to the communication circuit; the communication circuit is used to transmit the received broadcast data and coordinate data to the communication base station.

[0047] The scanning circuit can be a Bluetooth scanning circuit, and the node collar can be a Bluetooth node collar. The scanning circuit scans the broadcast data of surrounding matching node collars, processes the broadcast data to obtain Bluetooth data, and sends the Bluetooth data to the processing circuit. The positioning circuit receives coordinate data from positioning satellites and sends the coordinate data to the processing circuit. The processing circuit processes the Bluetooth data to obtain first processing information and processes the coordinate data to obtain second processing information. The processing circuit also transmits the first and second processing information to the communication circuit. The communication circuit transmits the first and second processing information to a communication base station.

[0048] In practical applications, based on the coverage area of ​​the scanning circuit, surrounding livestock will wear matching node collars. These collars continuously broadcast data containing relevant information, which the scanning circuit actively acquires. The broadcast data may include body temperature and step count, among other things. The Bluetooth node collar does not contain communication or scanning circuits. Instead, it incorporates sensors for body temperature and step count data. After acquiring this information, the sensors transmit the broadcast data to surrounding Bluetooth scanning circuits via Bluetooth.

[0050] In one embodiment, the positioning satellite can be a BeiDou satellite or a GPS satellite, providing accurate coordinate information for devices in outdoor grazing environments such as grasslands, enabling precise knowledge of the livestock's geographical location. Upon receiving coordinate data from the positioning satellite, the positioning circuit sends this data to the processing circuit. After processing, the relevant location coordinates are uploaded to the BeiDou satellite via the BeiDou communication circuit, allowing the user to know the current location of the livestock.

[0051] The processing circuit undertakes the core data processing tasks. On one hand, it processes the Bluetooth data from the scanning circuit to obtain first-level processing information, such as analyzing the individual animal number corresponding to the collar and some status indicators. On the other hand, it processes the coordinate data from the positioning circuit to obtain second-level processing information, such as performing format conversion and error correction on the coordinate data to make it more accurate and standardized. The processed first and second-level processing information are then transmitted to the communication circuit. In one embodiment, such as... Figure 2 As shown, the processing circuit includes a processor chip, which may be model FM33A045EV.
