[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figure 1-4 The shipborne satellite communication antenna system shown includes a mounting plate 1 and a power supply 2 disposed on the mounting plate 1;

[0025] A base 3 is provided on the upper side of the mounting plate 1;

[0026] A fixing rod 6 is fixedly connected to the upper outer wall of the base 3;

[0027] A beacon receiver 9 is provided on the left side of the fixed rod 6, a parabolic plate 11 is provided on the upper side of the beacon receiver 9, and a feed source 10 is provided on the circular inner wall of the parabolic plate 11.

[0028] A cross motor 7 is installed on the right side of the beacon receiver 9 to drive the parabolic panel 11 to tilt and swing back and forth. A pitch motor 12 is installed on the front side of the beacon receiver 9 to drive the parabolic panel 11 to tilt and swing left and right. An azimuth motor 13 is installed on the upper outer wall of the base 3 to drive the parabolic panel 11 to rotate horizontally. The shipborne satellite communication antenna system is based on the mounting plate 1 as the supporting component. The power supply 2 supplies power to the entire system. The base 3 is fixed on the mounting plate 1, and the fixing rod 6 on it is used to support the beacon receiver 9 and other components. When working, the host computer issues a command, and the power supply 2 powers the power supply module. At this time, the GPS, accelerometer, magnetometer and gyroscope start to work, collect data such as the ship's position and attitude, and transmit them to the controller. The chip inside the controller performs complex calculations based on this data to accurately calculate the required rotation angle of the turntable. Subsequently, the chip sends a drive signal to control the cross motor 7 to drive the parabolic panel 11 to tilt and swing back and forth, the pitch motor 12 to drive the parabolic panel 11 to tilt and swing left and right, and the azimuth motor 13 to drive the parabolic panel 11 to rotate horizontally. This enables precise multi-angle adjustment of the parabolic panel 11 to ensure alignment with the satellite. At the same time, the system obtains the antenna's attitude data in real time through the communication port and uploads it to the host computer, allowing operators to monitor the antenna status in real time and achieve effective monitoring and management of the antenna. The parabolic panel 11 is a 0.5-meter Ku-band reflector antenna.

[0029] like Figure 1 and Figure 2 As shown, a fixed frame 8 is fixedly connected between the outer walls of the front and rear ends of the beacon receiver 9, and a transmission rod 16 is fixedly connected to the outer wall of the left end of the cross motor 7 to transmit the power of the cross motor 7 to the fixed frame 8 and drive the parabolic panel 11 to rotate.

[0030] When the cross motor 7 receives the drive signal calculated by the controller, the rotor inside the motor starts to rotate. Since the outer wall of the left end of the motor is fixedly connected to the transmission rod 16, the rotational motion of the motor rotor is directly transmitted to the transmission rod 16, causing the transmission rod 16 to rotate along with it. The rotation of the transmission rod 16 will drive the fixed frame 8 to synchronously drive the parabolic panel 11 to rotate.

[0031] like Figure 3 As shown, a drive rod 17 is fixedly connected to the outer wall of the rear end of the pitch motor 12, and traction rods 18 are provided on the circular outer walls of both the left and right ends of the drive rod 17.

[0032] The motor rotor inside the pitch motor 12 rotates. Since the outer wall of the rear end of the pitch motor 12 is fixedly connected to the drive rod 17, the rotational power of the motor rotor is transmitted to the drive rod 17. The drive rod 17 rotates accordingly and, with the cooperation of the traction rod 18, drives the beacon receiver 9 to rotate, which in turn drives the parabolic panel 11 to rotate.

[0033] like Figure 1 As shown, a transmission plate 4 is fixedly connected to the outer wall of the right end of the azimuth motor 13 to indicate the angle position of rotation. The azimuth motor 13 drives the base 3 to rotate under the restriction of the mounting plate 1.

[0034] When the azimuth motor 13 drives the base 3 to rotate, the transmission plate 4 rotates accordingly. The operator can intuitively obtain the rotation angle information of the azimuth motor 13 from the transmission plate 4. When the azimuth motor 13 is working, the rotation of its output shaft drives the base 3 connected to it to rotate under the restriction of the mounting plate 1.

[0035] like Figure 2 and Figure 3 As shown, the other end of the cross motor 7, the pitch motor 12 and the azimuth motor 13 are all equipped with signal receivers 15 to receive control signals and issue corresponding commands, and the other end of the transmission rod 16 and the drive rod 17 are all equipped with positioning shafts.

[0036] The signal receivers 15, which are installed at the other end of the cross motor 7, pitch motor 12, and azimuth motor 13, are key components for information interaction between the motors and the control system. When the controller calculates the angle information that the parabolic panel 11 needs to be adjusted based on the data collected by GPS, accelerometer, magnetometer, and gyroscope, it sends out the corresponding control signals. These control signals are received by the signal receivers 15, which convert the received electrical signals into instructions that the motors can recognize, thereby controlling the cross motor 7, pitch motor 12, and azimuth motor 13 to perform corresponding actions, accurately driving the parabolic panel 11 to adjust its angle in the front-back, left-right, and horizontal directions, ensuring that the antenna is always pointed at the satellite and maintaining good communication signal reception.

[0037] like Figure 1 As shown, a control box 5 is fixedly connected to the outer wall of the right end of the fixing rod 6, and a spiral antenna 14 is fixedly connected to the outer wall of the upper end of the base 3.

[0038] The control box 5, which is fixedly connected to the outer wall of the right end of the fixed rod 6, is one of the core control hubs of the shipborne satellite communication antenna system. The control box 5 integrates a variety of key electronic components and circuit modules, and undertakes important tasks such as signal processing, command transmission and system coordination. The spiral antenna 14, which is fixedly connected to the outer wall of the upper end of the base 3, is mainly used for auxiliary signal reception and transmission in the shipborne satellite communication antenna system.

[0039] The implementation principle of this embodiment is as follows: The shipborne satellite communication antenna system uses mounting plate 1 as the basic supporting component, power supply 2 to power the entire system, and base 3 fixed on mounting plate 1. The fixing rod 6 on it is used to support components such as beacon receiver 9. During operation, the host computer issues a command, and power supply 2 powers the power supply module. At this time, GPS, accelerometer, magnetometer, and gyroscope start working, collecting data such as ship position and attitude, and transmitting them to the controller. The chip in the controller performs complex calculations based on this data to accurately calculate the required rotation angle of the turntable. Subsequently, the chip sends a drive signal to control the cross motor 7 to drive the parabolic panel 11 to tilt and swing in the forward and backward directions, the pitch motor 12 to drive the parabolic panel 11 to tilt and swing in the left and right directions, and the azimuth motor 13 to drive the parabolic panel 11 to rotate in the horizontal direction, realizing multi-angle precise adjustment of the parabolic panel 11 to ensure alignment with the satellite. At the same time, the system obtains the antenna attitude data in real time through the communication port and uploads it to the host computer, so that the operator can keep track of the antenna status in real time and realize effective monitoring and management of the antenna. The parabolic panel 11 is a 0.5-meter band reflector antenna.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
