[0020] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0021] Example

[0022] like Figs. 1-3 As shown, the angle adjustment mechanism and the main control module 1 are mounted on the mounting bracket 13. The dual receiving mechanism and the signal fusion processing module are mounted on the angle adjustment mechanism. The main control module 1 is provided with a signal processing unit and a control unit. The signal processing unit is used to receive and process the Beidou satellite signals transmitted by the dual receiving mechanism. The control unit controls the movement of the angle adjustment mechanism according to the processing result of the signal fusion processing module. The angle adjustment mechanism includes: a horizontal rotating ring 2, a concave ring limiting block 19, a horizontal gear set 3, a horizontal drive motor 4, a loop-shaped vertical adjustment block 5, a vertical arc slide rail set 6, a vertical arc slider set 7, a vertical adjustment plate 8, a pair of vertical adjustment shafts 9, a vertical drive motor 10, a vertical gear set 11, an arc extrusion block set 12, an arc limiting plate set 14, an arc-shaped metal block set 15, an adjustable electromagnet set 16, and an adjustable magnet set 17.

[0023] Specifically, the concave annular limiting block 19 is mounted on the mounting bracket 13; the horizontal rotating ring 2 is movably inserted into the concave annular limiting block 19; the horizontal drive motor 4 is mounted on the mounting bracket 13; the horizontal gear set 3 is mounted on the inner side of the horizontal drive motor 4 and the concave annular limiting block 19; the loop-shaped vertical adjusting block 5 is inserted into the horizontal rotating ring 2; the vertical arc slide rail set 6 is evenly installed on the inner side of the loop-shaped vertical adjusting block 5; the vertical arc slider set 7 is mounted on the vertical adjusting plate 8, and the vertical arc slider set 7 is movably inserted into the inner side of the vertical arc slide rail set 6; a pair of vertical adjusting shafts 9 are inserted on both sides of the vertical adjusting plate 8; and... A pair of vertical adjustment shafts 9 are inserted into the U-shaped vertical adjustment block 5 via bearing slides. The vertical drive motor 10 is mounted on the horizontal rotating ring 2. The vertical gear set 11 is mounted on the vertical drive motor 10 and the vertical adjustment shafts 9. The vertical arc slide set 6 has several extrusion arc grooves. The arc extrusion block set 12 is movably inserted into the inner side of several extrusion arc grooves. The arc limiting plate set 14 is mounted on the arc extrusion block set 12. The arc-shaped metal block set 15 is evenly mounted on the vertical arc slide set 6. The adjustable magnet set 17 is mounted on the arc limiting plate set 14. The adjustable electromagnet set 16 is mounted on the arc-shaped metal block set 15.

[0024] It should be noted that, during installation, the device is fixed to the equipment using bolts through the holes on the mounting bracket 13 to ensure its stability and reliability. After installation, the horizontal drive motor 4 operates, driving the horizontal gear set 3 on its drive end. The horizontal gear set 3, using a gear ratio and speed ratio, performs a stable 1-degree rotation adjustment on the horizontal rotating ring 2, thereby adjusting the horizontal rotating ring 2 to its initial angular position. Similarly, the vertical drive motor 10 operates to ensure that the horizontal and vertical angles of the satellite alignment device are consistent with the initial pointing of the equipment. After power is turned on, the main control module 1 initializes, the signal processing unit and control unit start, and the signal fusion processing module and angle adjustment mechanism enter standby mode. The pair of receiving antennas 18 in the dual receiving mechanism begin receiving BeiDou satellite signals. The signals are amplified by a preamplifier and a low-noise amplifier, and interference is filtered out by a filter, transmitting the clean signal to the signal processing unit. The signal processing unit demodulates and decodes the BeiDou satellite signals from the dual receiving mechanism, extracting navigation and time information. At the same time, the signal strength detection unit detects the signal strength to ensure that the received signal quality meets the requirements. The interference detection unit detects interference in the received signal. If strong interference is detected, the signal processing unit further processes the signal using a filtering algorithm to remove interference components and ensure signal purity. The signal processing unit calculates the current geographical location and time parameters based on navigation and time information, and further calculates the azimuth and elevation angles of the target satellite. The calculation results are transmitted to the control unit. The control unit, based on the calculated azimuth and elevation angles and the detection results from the horizontal and vertical angle sensors, calculates the angle difference that needs adjustment, generates a control signal, and transmits it to the control circuit. The control circuit coordinates the movement of the horizontal drive motor 4 and the vertical drive motor 10 based on the received control signal. The horizontal and vertical angles of the equipment are adjusted through the operation of the horizontal drive motor 4 and the vertical drive motor 10. During the adjustment process, the horizontal and vertical angle sensors detect the angle changes of the vertical adjustment plate 8 in real time and feed the detection results back to the control unit. Based on the feedback results, the control unit dynamically adjusts the motor's motion parameters to ensure the accuracy of the angle adjustment. The signal fusion processing module fuses the received BeiDou satellite signals to improve the reliability and accuracy of the azimuth data. The signal fusion processing module can perform weighted averaging of signals received from multiple antennas, further reducing random errors in the signals and improving the system's anti-interference capability. After the initial satellite alignment is completed, the satellite alignment device will continuously monitor the received BeiDou satellite signals. The signal processing unit and the signal fusion processing module will process the signals in real time. The control unit will dynamically adjust the movement of the horizontal drive motor 4 and the vertical drive motor 10 based on the processing results and sensor feedback data to ensure high-precision positioning and rapid satellite alignment of the satellite alignment device in dynamic environments.
