Specifically, as Figure 1 shown, the device includes a Beidou communication circuit, a host scanning circuit, a positioning circuit, a power supply circuit, and a processor module. The Beidou communication circuit is connected to the processor module and receives instructions and data sent by the processor module, and establishes a communication connection with Beidou satellites; the host scanning circuit is used to scan the broadcast data of the surrounding supporting node collars and parse and pack the data and send it to the processor module; the positioning circuit is used to receive BD and GPS positioning satellite data, parse the corresponding positioning coordinates, and send the data to the processor module; the power supply circuit is used to supply power to the processor module, the host scanning circuit, and the positioning circuit, and the processor module is used to control the Beidou communication circuit, the host scanning circuit, and the positioning circuit to work and receive and parse the corresponding data.

[0026] The Beidou communication circuit includes a Beidou power supply circuit and a Beidou communication chip circuit. Among them, the Beidou power supply circuit includes a DC-DC boost chip and its peripheral circuit, and its model is SGM6611CYTQV11G / TR. The battery voltage is boosted by the DC-DC boost chip and then used by the Beidou chip. The Beidou communication chip circuit includes Beidou transceiver antennas J5 and J6, a Beidou communication module XM1302E, and a Beidou communication authorized SIM card. As Figure 2As shown in the figure, the Beidou antenna J5 is used to receive data and instructions from Beidou satellites and transmit them to the RF_IN pin of the Beidou communication module XM1302E; the Beidou transceiver antenna J6 is used to transmit the data and instructions sent from the RF_OUT pin of the Beidou communication module XM1302E to Beidou satellites; the Beidou communication circuit receives the instructions and data of the processor module through the serial port and transmits and receives Beidou satellite data through the Beidou antenna.

[0027] As Figure 3 shown in the figure, the host scanning circuit consists of a LORA gateway scanning chip and its peripheral circuits, which are responsible for scanning the broadcast data of the supporting LORA node collars around the device, parsing and packing the LORA data, and sending it to the processor module through the serial port. The model of the LORA gateway scanning chip is TP1107 or TP2210. Preferably, in this embodiment, TP1107 is adopted. The RF_ANT pin of this chip is connected to the radio frequency antenna for scanning the supporting LORA node collars; the GPIO4 pin is used as the DTE wake-up module, entering the sleep state at a low level and waking up at a high level; the SWDIO and SWCLK pins are connected to the programming and debugging interface; the RE SET pin is connected to the reset module to implement the system reset function; the DBG_TXD and DBG_RXD pins are connected to the debugging serial port; the GPIO5 pin is used as a network-configurable reset output signal; the VDD1 and VDD2 pins are connected to the filter circuit as the power input terminals, and the filter circuit is composed of transient voltage suppression diodes TVS and capacitors C1 - C5 in parallel.

[0028] As Figure 4 shown in the figure, the positioning circuit consists of a GNSS positioning chip AT6558R and its peripheral circuits. The antenna is connected to the input pin IN of the filter SAFFBIG56 through the operational amplifier AT2569, and then output to the RF_IN pin of the positioning chip AT6558R.

The voltage detection circuit is composed of a voltage monitoring and protection chip SGM890B and its peripheral circuit. When the voltage is lower than the set value, the MOS transistor is turned off to cut off the battery's external discharge circuit, thereby protecting the battery. At the same time, the processor module collects the battery voltage through the built-in ADC to prevent the device from operating unstably at low voltage.

[0031] As Figure 7 shown, the processor module is composed of an MCU with the model number FM33A045EV, which is responsible for controlling the Beidou communication chip, the LORA gateway chip, and the GNSS positioning chip to work and receiving and parsing the corresponding data.

The model of the Bluetooth scanning chip is TLSR8251F512ET24. The pin ANT of this chip is connected to the antenna, which is used to scan the supporting Bluetooth node ear tags.
