[0020] like Figure 1-5 As shown, a Beidou high-precision portable positioning terminal circuit integrating laser ranging includes a power management module 1, a TK01 module 2 and a TB01 module 3, and also includes a non-laser ranging module 4 connected to the TK01 module, a laser ranging module 5 and a Bluetooth module 6. The TK01 module 1 includes a Bluetooth management unit, a non-ranging laser management unit, an FM management unit and a Beidou management unit, and also includes three serial ports UART0, UART1, UART2 and eleven GPIO ports GPIO0, GPIO1, GPIO2, GPIO3, GPIO4, GPIO5, GPIO6, GPIO11, GPIO13, GPIO19, GPIO22, two of which, GPIO6 and GPIO11, are connected to the battery management module 1 and the non-ranging laser module 4 respectively, two of which, GPIO2 and GPIO13, and one serial port UART1 are connected to the Bluetooth module 6, one of which, the serial port UART0 is connected to the TYPE-C interface 7, one of which, the serial port UART2 is connected to the TB01 module 3, the TB01 module 3 is also connected to the ranging laser module 5, and the ranging laser module 5 is also connected to a GPIO port GPIO22 of the TK01 module 1.

[0021] Specifically, the ranging laser module 5 includes a laser transmitter and a laser sensor, the TB01 module 3 includes a laser power management chip Q3 (IISCB2903) and a laser transceiver interface P1, the laser transmitter and the laser sensor are both connected to the laser transceiver interface P1 and the laser power management chip Q3, the control pin LASER_RANGING-PW_EN-B of the laser power management chip Q3 and the data pins UART1_RX and UART1_TX connected to the laser transceiver interface P1 are connected to the TK01 module, wherein the control pin LASER_RANGING-PW_EN-B of the laser power management chip Q3 is connected to the 11th pin of the main control chip U9 (M2012), and the data pins UART1_RX and UART1_TX of the laser transceiver interface P1 are respectively connected to the 15th and 16th pins of the combined receiving chip U18 (SK9148-2), and the main control chip U9 and the combined receiving chip U18 are both included in the TK01 module 1.

[0022] The TK01 module 1 is also connected to an indication circuit, which includes three LED indicator lights, namely a Bluetooth operation indicator light BT-LED, a Beidou positioning operation indicator light GNSS-LED and an FM operation indicator light FM-LED, which are respectively connected to the GPIO ports GPIO4, GPIO3 and GPIO5 of the TK01 module 1.

[0023] The control end of the power management module 1 is connected to the GPIO port GPIO6 of the TK01 module. The power management module 1 is also connected to the power indicator light PW-IN-LED. The power management module 1 also includes a battery low power mark output pin 8 connected to the GPIO port GPIO0 of TK01.

[0024] The TK01 module is connected to the TPYE-C interface via a serial port to TYPE-C unit, and the control chip of the serial port to TYPE-C unit is U1 (CH340N).

[0025] Beidou positioning terminals based on FM broadcasting have four major technical advantages: First, the coverage is wide. The coverage of a single FM broadcasting station is wider than that of a mobile communication base station, and it can achieve low-altitude full-area coverage. Second, the user capacity is large, which can accommodate requests from ultra-large-scale users, and will not cause communication channel congestion due to high concurrent service requests from users, thus ensuring service stability. Third, it has strong security. FM is a one-way data transmission. The device terminal can only receive data. Confidential data and user privacy data cannot be transmitted to the outside through the Internet, and there is no risk of information being confidential. Fourth, it has low cost. FM broadcasting technology is based on the upgrade and transformation of the existing radio station infrastructure, and the user terminal has no communication cost, so the construction and use costs are relatively low. On the one hand, it can effectively solve the problem that the positioning terminal cannot perform high-precision positioning in areas without mobile communication networks or unstable communication networks. On the other hand, it is suitable for high-precision location information collection in a safe and confidential environment, and can meet the application requirements of CORS system service coverage, large capacity, and high security.

[0026] The present invention can integrate functional components such as FM reception, Beidou positioning, and visible laser ranging in the circuit into a smaller shell, and the finished product is small in size and easy to carry.

[0027] Visible laser ranging can be used in scenarios where RTK signals are blocked (such as passing under a bridge or next to a wall). Its continuous changing direction ranging can be used for calculation to ensure that the positioning result of the obstructed position is accurate based on the last reliable RTK positioning result.

[0028] The peripheral circuits and connection relationships of each electronic chip not described in detail in the present invention are all prior art, and those skilled in the art can select appropriate electronic components for connection based on the prior art without any creative work.

[0029] The embodiments described in the present invention are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made to the technical solutions of the present invention by engineers and technicians in this field should fall within the protection scope of the present invention. The technical contents for which protection is sought in the present invention have all been recorded in the claims.
