[0027] Specifically, Figure 2 As shown, the 4G Bluetooth acquisition and positioning collar based on solar power supply includes a solar module, an energy storage module, a 4G communication module, a Bluetooth host scanning module, a positioning circuit and a processor module. The solar module is connected to the processor module and the energy storage module respectively. The processor module is connected to the 4G communication module, the Bluetooth host scanning module and the positioning circuit respectively. The 4G communication module receives the instructions and data sent by the processor module and uploads the data to the remote server through the 4G network; the Bluetooth host scanning circuit is used to scan the surrounding Bluetooth ear tag broadcast data and parse and package the data to send to the processor module; the positioning circuit is used to receive positioning satellite data, parse the corresponding positioning coordinates, and send the data to the processor module; the processor module is used to control the 4G communication module, the Bluetooth host scanning circuit, and the positioning circuit to work and receive and parse the corresponding data. Through solar power generation and energy storage, long battery life is achieved, which provides a guarantee for long-term uninterrupted monitoring of livestock such as cattle, sheep, horses and camels.

[0028] Furthermore, the solar module includes a solar panel and a micro energy collection chip, the solar panel is connected to the micro energy collection chip, and the micro energy collection chip is connected to the energy storage module and the processor module respectively. Figure 3As shown, the micro energy collection chip 1b is implemented using the MKS3061 chip and its peripheral circuits. The MKS3061 chip is a micro energy collection management chip that integrates functions such as energy management, charge and discharge management, and energy storage device management. It can achieve cold start in energy input scenarios as low as 400mV voltage and 15μW power. After startup, it can obtain DC power from energy conversion devices such as solar panels to charge energy storage elements such as rechargeable batteries or supercapacitors, and can provide a stable operating voltage for the processor module through two LDO regulators.

[0029] like Figure 4 As shown, the 4G communication module includes a wireless communication chip and a communication authorization SIM card. The wireless communication chip receives instructions and data from the processor module through a serial port. The wireless communication chip adopts an EC800 series chip. In this embodiment, the EC800ECNCG-N03-SNNSA chip is preferably used, and a 2-bit bidirectional voltage level converter RS0102YH8 is used to realize the signal receiving and sending conversion.

[0030] like Figure 5 As shown in the figure, the Bluetooth host scanning circuit consists of a Bluetooth scanning chip and its peripheral circuits. The Bluetooth gateway scanning circuit is used to scan the Bluetooth ear tag broadcast data around the device and parse and package the Bluetooth data, and send it to the processor module through the serial port. The model of the Bluetooth scanning chip is TLSR8251F512ET24. The ANT pin of the chip is connected to the antenna, which is used to scan the Bluetooth node ear tag and receive data.

[0031] like Figure 6 As shown in the figure, the positioning circuit is composed of the GNSS positioning chip AT6558R and its peripheral circuits. The antenna is connected to the input pin IN of the filter SAFBBIG56 through the operational amplifier AT2569, and then output to the RF_IN pin of the positioning chip AT6558R.
