Description

Technical Field

[0001] This invention relates to the field of aerial stabilization turntables for antennas, specifically to an aerial turntable system for antennas. Background Technology

[0002] An antenna turntable system is an essential device for driving the rotation of an antenna. By pointing the antenna in different directions through the turntable, the antenna can radiate in different directions, thus realizing the antenna's functions in various directions (such as communication, search, etc.). Existing antenna turntables can generally only adjust the antenna's heading, not its elevation attitude, making it difficult to keep the antenna pointing in the same direction at all times. Summary of the Invention

[0003] A design method for an antenna turntable system is proposed to adjust the antenna's attitude on the turntable so that the antenna always maintains a stable attitude.

[0004] Technical solution

[0005] An aerial turntable system for antennas includes a turntable 1, an antenna mount 2, a turntable controller 3, a sensor module 4, a tilt controller 5, a processing unit 6, and an electric actuator 7. The antenna mount 2 has an inner and outer frame structure, and the turntable 1 is connected to the outer frame of the antenna mount 2 via a connector. The inner and outer frames of the antenna mount 2 are connected by bearings, allowing the inner frame to rotate freely vertically within the outer frame via the bearings. The inner frame of the antenna mount 2 is connected to the electric actuator 7 via an actuation rod connector.

[0006] Turntable 1 can rotate freely within a 0-360° azimuth range. Antenna mount 2 is used to mount the antenna. Turntable controller 3 receives instructions from processing unit 6 and controls the adjustment of the azimuth angle of turntable 1. Sensor module 4 is used to measure the azimuth and elevation angles of the turntable. Tilt controller 5 receives instructions from processing unit 6 and controls the movement of electric push rod 7. Processing unit 6 receives information collected by sensor module and sends control instructions to turntable controller 3 and tilt controller 5. After electric push rod 7 moves, the inner frame of antenna mount 2 rotates vertically as electric push rod 7 extends or retracts, thereby adjusting the elevation angle of the antenna.

[0007] Furthermore, during operation, the sensor module 4 sends the acquired azimuth and elevation angle parameters to the processing unit 6.

[0008] Furthermore, after receiving the azimuth and pitch angle parameters, the processing unit 6 compares them with the set azimuth and pitch angles, and sends the control command to the turntable controller 3 and the tilt controller 5.

[0009] Furthermore, the turntable controller 3 controls the turntable 1 to adjust the azimuth angle, and the tilt controller 5 adjusts the pitch attitude of the inner frame of the antenna bracket 2 by controlling the extension and retraction of the electric push rod 6, so that the spatial angle of the mission antenna remains unchanged, thereby ensuring that the antenna can always face a fixed direction.

[0010] Furthermore, the tilt sensor in the sensor module 4 is an SVT620.

[0011] Furthermore, the tilt controller 5 is a programmable controller T910.

[0012] Furthermore, the power of the electric actuator 7 should be no less than 120N.

[0013] Furthermore, the electric push rod 7 is required to complete the adjustment of the antenna angle within 5 seconds.

[0014] Furthermore, the antenna's elevation range is 0° to R°, the antenna mount 2 has a length of L, and the electric push rod 7 has a speed of V. Technical effect

[0015] This invention measures the azimuth and elevation angles of the turntable using a sensor module, providing input to the turntable controller and tilt controller. This improves the turntable's ability to adjust the azimuth and elevation angles, ensuring that the antenna always faces a fixed direction and enhancing the stability of antenna operation.

[0019] The present invention will be further described below with reference to embodiments. The following descriptions are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0020] The specific implementation method is as follows:

[0021] During operation, sensor module 4 sends the acquired azimuth and elevation angle parameters to processing unit 6. Processing unit 6 receives these parameters, compares them with the set azimuth and elevation angles, and sends control commands to turntable controller 3 and tilt controller 5. Turntable controller 3 controls turntable 1 to adjust the azimuth angle, while tilt controller 5 adjusts the elevation attitude of the inner frame of antenna mount 2 by controlling the extension and retraction of electric push rod 6, ensuring that the spatial angle of the mission antenna remains constant and that the antenna always faces a fixed direction.

[0022] An aerial turntable system for antennas includes a turntable 1, an antenna mount 2, a turntable controller 3, a sensor module 4, a tilt controller 5, a processing unit 6, and an electric actuator 7. The antenna mount 2 has an inner and outer frame structure, and the turntable 1 is connected to the outer frame of the antenna mount 2 via a connector. The inner and outer frames of the antenna mount 2 are connected by bearings, allowing the inner frame to rotate freely vertically within the outer frame via the bearings. The inner frame of the antenna mount 2 is connected to the electric actuator 7 via an actuation rod connector.

[0023] Turntable 1 can rotate freely within a 0-360° azimuth range. Antenna mount 2 is used to mount the antenna. Turntable controller 3 receives instructions from processing unit 6 and controls the adjustment of the azimuth angle of turntable 1. Sensor module 4 is used to measure the azimuth and elevation angles of the turntable. Tilt controller 5 receives instructions from processing unit 6 and controls the movement of electric push rod 7. Processing unit 6 receives information collected by sensor module and sends control instructions to turntable controller 3 and tilt controller 5. After electric push rod 7 moves, the inner frame of antenna mount 2 rotates vertically as electric push rod 7 extends or retracts, thereby adjusting the elevation angle of the antenna.

[0024] During operation, sensor module 4 sends the acquired azimuth and elevation angle parameters to processing unit 6. Upon receiving these parameters, processing unit 6 compares them with the preset azimuth and elevation angles and sends control commands to turntable controller 3 and tilt controller 5. Turntable controller 3 controls turntable 1 to adjust the azimuth angle, while tilt controller 5 adjusts the elevation attitude of the inner frame of antenna mount 2 by controlling the extension and retraction of electric push rod 6, ensuring that the spatial angle of the mission antenna remains constant and thus guaranteeing that the antenna always faces a fixed direction. The tilt sensor in sensor module 4 is an SVT620. The controller in tilt controller 5 is a programmable logic controller (PLC) T910. The specific working logic of the processing unit 6 is as follows: The processing unit 6 receives the azimuth and elevation angles collected by the sensors. When adjustments to the azimuth and elevation angles are needed, the operator on the ground sends the angles to be adjusted to the processing unit 6. The processing unit 6 judges the target angle and the current angle, calculates the required azimuth and elevation angles, and sends these angles to the turntable controller and tilt controller, which then drive the motor to adjust the angles. The power of the electric push rod 7 should be no less than 120N. The electric push rod 7 must complete the antenna angle adjustment within 5 seconds. The antenna elevation range is 0° to R°, the length of the antenna bracket 2 is L, and the speed V of the electric push rod 7 is required to be...
