[0037] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings. The described implementation modes are only for example and are not intended to limit the present invention.

[0038] In one aspect of the embodiments of the present application, a semi-implantable Beidou positioning module is provided, such as Figure 1 As shown, it includes: an in-vivo implantable module and an in-vivo transceiver module.

[0039] The body implant module is used to be implanted in the human body, including a Beidou positioning module, a body Bluetooth module, and an implanted battery arranged on a flexible PCB board. The implanted battery is used to power the body implant module. The implanted battery is connected to the Beidou positioning module and the body Bluetooth module, and the body Bluetooth module is connected to the Beidou positioning module. In this example, the hardware layout and appearance of the body implant module are as follows: Figure 4 shown.

[0040] Among them, the external transceiver module is provided on a wearable device for wearing on the human body, and includes an external Bluetooth module, a 4G communication module, an external battery, and a display module provided on a rigid PCB board. The external Bluetooth module is connected to the internal Bluetooth module via Bluetooth. The external battery is used to power the external transceiver module. The external battery is connected to the external Bluetooth module, the 4G communication module, and the display module. The external Bluetooth module is connected to the 4G module and the display module. The display module is used to display the working status and positioning results, and a low-power OLED screen can be used.

[0041] Specifically, Figure 2 As shown, the Beidou positioning module includes a Beidou microstrip antenna, a SAW filter connected to the Beidou microstrip antenna, an LNA connected to the SAW filter, and a Beidou positioning SOC chip connected to the LNA. The in-vivo Bluetooth module includes an in-vivo Bluetooth MCU and an in-vivo Bluetooth antenna connected to the in-vivo Bluetooth MCU. The in-vivo Bluetooth MCU is connected to the Beidou positioning SOC chip through a serial port, and an implanted battery is connected to the Beidou positioning SOC chip, the SAW filter, and the in-vivo Bluetooth MCU. In this example, the Beidou positioning SOC chip uses a micron-level positioning SOC bare chip, and the in-vivo Bluetooth MCU uses a low-power bare chip, which is convenient for packaging in a volume-controllable manner on a flexible PCB board to achieve in-vivo implantation.

[0042] Specifically, Figure 3As shown, the 4G communication module includes a 4G module, a SIM card connected to the 4G module and a 4G antenna. The external Bluetooth module includes an external Bluetooth MCU and an external Bluetooth antenna connected to the external Bluetooth MCU. The external Bluetooth MCU is connected to the 4G module through a serial port, and the external battery is connected to the 4G module, the external Bluetooth MCU and the display module. Among them, the 4G module is a 4G chip, which is suitable for the 4G, 3G and 2G transmission modes of the three major communication operators. During the data transmission process, the packet loss rate is extremely low and the transmission speed is fast. It has a SIM card interface and a 4G antenna interface to facilitate the connection of the SIM card and the 4G antenna.

This layout can control the packaging volume of the external transceiver module and facilitate the portability of the wearable.

[0043] When the Beidou positioning module is in working state, it receives Beidou satellite signals through the Beidou microstrip antenna, and after filtering processing by the SAW filter and low-noise amplification processing by the LNA, it enters the Beidou positioning SOC chip, and the Beidou positioning SOC chip processes it to form a satellite positioning signal; at the same time, it can be transmitted through the internal Bluetooth MCU via the internal Bluetooth antenna to the external Bluetooth antenna to be received by the external Bluetooth MCU, and transmitted to the 4G chip and display module. The 4G chip can send the satellite positioning signal from the mobile network to the cloud server through the 4G antenna, and the display module is used to display the positioning information.

[0044] At the same time, the extracorporeal transceiver module is also used to receive differential information obtained from the cloud server, and transmit it to the internal implanted module through the external Bluetooth MCU and the external Bluetooth antenna. After receiving the internal Bluetooth MCU, the internal Bluetooth antenna transmits it to the Beidou positioning SOC chip. The Beidou positioning SOC chip combines the differential information and the satellite positioning signals obtained by itself to perform RTK positioning algorithm calculations to achieve high-precision positioning.

[0045] In this example, by adopting the materials and methods of bare chips and flexible PCB circuits, the navigation and positioning technology is integrated into a semi-implantable device, which has the advantages of easy use and high integration into the human body, and improves accuracy and range.

[0053] When the mobile station works in sleep mode, the external Bluetooth module of the mobile station controls itself and the 4G communication module, Beidou positioning module and display module are all in sleep state. At this time, the mobile station does not perform positioning.

[0054] Specifically, Figure 8 The figure shows the working mode process of the base station of the Beidou positioning communication system. After the external transceiver module is turned on, the power-on command of the internal implanted module is sent. The internal implanted module is turned on, and the Beidou positioning module starts positioning to determine whether differential positioning is currently being performed:
