Abstract
Description
Technical Field
[0001] This utility model relates to the field of ultra-shortwave communication radio technology, specifically to an automatic pointing device for a directional antenna of a ground-to-air communication radio. Background Technology
[0002] Air-to-ground communication, as an important form of communication, is widely used in the field of civil aviation communication support due to its long communication distance and strong anti-interference capabilities.
[0003] Currently, to improve communication range and anti-interference performance, air-to-ground communication equipment often uses narrow-beam antennas. These antennas have strong directivity, and a communication link can only be established when the beam is aligned with the target with a certain precision. Therefore, both parties often need to spend a considerable amount of time searching and adjusting to align the antennas and achieve normal communication.
[0004] Obviously, relying solely on the operator's senses for manual operation results in a long antenna pointing adjustment time, making it difficult to achieve precise alignment. To ensure the speed and reliability of communication link establishment, it is of great significance to research an automatic antenna alignment system for radio stations with a high degree of automation, fast alignment speed, and high accuracy. Based on this, an automatic pointing device for the directional antenna of a ground-to-air communication radio station is proposed. Utility Model Content

[0022] 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.
[0023] Example 1
[0024] Please see Figures 1-3An automatic pointing device for a directional antenna of an air-to-ground communication radio is disclosed. The device is capable of rapidly establishing air-to-ground communication when an airborne platform is at a certain altitude. It includes a gyroscope, a directional antenna, a GPS device, a variable-speed gimbal, a power supply, and a PC control terminal. The gyroscope establishes a data connection with the variable-speed gimbal, the variable-speed gimbal establishes a data connection with the GPS device, the directional antenna is mounted on the variable-speed gimbal and established a data connection with the variable-speed gimbal, the variable-speed gimbal is electrically connected to the power supply, and the variable-speed gimbal establishes a data connection with the PC control terminal.
[0025] In some embodiments, the variable-speed gimbal includes a remote communication module, a gimbal control module, and a rotation mechanism. The remote communication module establishes a data connection with the gimbal control module, the gimbal control module establishes a data connection with the rotation mechanism, and the remote communication module establishes a data connection with a PC control terminal. The power supply device provides +24V voltage to the device. The gyroscope device acquires the pitch and horizontal angles of the variable-speed gimbal. The GPS device acquires the position information of the directional antenna. The variable-speed gimbal controls the pointing direction of the directional antenna, which assists in directional antenna alignment. The directional antenna is used when the system is operating normally after antenna alignment is completed. Additionally, a set of calculation software is required, consisting of parameter setting and monitoring software and gimbal control software. The parameter setting and monitoring software mainly sets and monitors the operating parameters and status of the devices within the system, as well as controls the automatic antenna alignment process. The gimbal control software mainly initializes and controls the gimbal. By issuing commands and combining device status information with data received from other devices, it collaboratively completes the antenna alignment function. All status acquisition and control are completed on the PC control terminal.
[0026] In this utility model, the gimbal control module is the most core module, which is usually installed on the variable speed gimbal. It needs to perform two main functions: decode the received console commands and convert them into control signals to control the motor; and drive the motor on the gimbal to perform corresponding actions according to the control signals.
[0027] In addition to the above-mentioned components, the status signal input device of this utility model can also be a signal detection device or any device that can quickly detect the strength of the transmitted signal. It can also optionally include circuit combinations that achieve the same function. The pointing device designed according to this utility model can quickly establish a communication link with the air platform, and the device circuit is relatively simple, with low implementation cost and high reliability.
[0028] Example 2
[0029] Figure 1 , Figure 2 and Figure 3The diagrams show the composition, working mode, and working principle of the pointing device designed according to this utility model.
[0030] like Figure 1 As shown, the pointing device designed according to this utility model includes: a gyroscope device for acquiring pitch and horizontal angles; a directional antenna for communication; a GPS device for acquiring location information; an omnidirectional DC variable speed gimbal for controlling direction; and a power supply device for providing power to the device with +24V voltage.
[0031] like Figure 2 As shown, the pointing device designed according to this utility model has antenna alignment software divided into two parts: parameter setting and monitoring software and PTZ control software. The parameter setting and monitoring software mainly sets and monitors the working parameters and status of the equipment within the system, as well as controls the automatic antenna alignment process. The PTZ control software mainly initializes and controls the PTZ. By issuing commands and combining equipment status information with data received from other equipment, it collaboratively completes the antenna alignment function.
[0032] like Figure 3 As shown, the pointing device designed according to this utility model requires a gimbal control system to control the horizontal or vertical rotation of the gimbal. The gimbal control system generally consists of a control console, a remote communication module, and a gimbal control module. The control console is used by the user to input control commands to the gimbal, such as moving in the up, down, left, and right directions. The remote communication module is used to enable communication between the gimbal and the control console, transmitting commands from the control console to the gimbal and feeding back data from the gimbal to the control console. The gimbal controller is the core module, usually installed on the gimbal, and needs to perform two main functions: decoding the received commands from the control console and converting them into control signals for the motor; and driving the motor on the gimbal to perform corresponding actions based on the control signals.
[0033] This example illustrates the working method and principle of this utility model using only a single pointing device operating on the same platform. Furthermore, when multiple pointing devices operate simultaneously on the same platform, the pointing device designed according to this utility model can still perform normal control.
[0034] Of course, this utility model can also be implemented using other structures, such as the hollow rotating platform that can be used in this utility model, and the control software can also be embedded.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
