Description

Technical Field

[0001] This utility model relates to the field of electromagnetic environment testing technology, and in particular to a directional antenna rotation control device. Background Technology

[0002] In traditional satellite station electromagnetic environment testing, operators need to rotate the antenna horizontally within a 0-360° range and then observe the spectrum displayed on a spectrum analyzer to determine if there are any interference signals in that location. Under normal monitoring conditions, this operation needs to be performed four times at each monitoring point—once in the morning, once at noon, once in the evening, and once at midnight—with each monitoring session lasting no less than 30 minutes. For any detected interference signals, the antenna angle needs to be repeatedly adjusted to find the maximum value of the interference signal. This process is time-consuming, labor-intensive, and involves a lot of repetitive work for the operators.

[0003] Meanwhile, in traditional satellite station electromagnetic environment testing tasks, the method of manually rotating the monitoring antenna and manually recording the antenna azimuth information is usually adopted. This method is prone to problems such as uneven antenna rotation and recording errors, which affect the test coverage and recording results, thus generating test errors. Utility Model Content

Detailed Implementation

[0038] The following is combined with Figures 1-10 This utility model will be described in detail.

[0039] A directional antenna rotation control device includes a rotating device 10, with a housing 20 mounted on top of the rotating device 10. The rotating device 10 drives the housing 20 to rotate synchronously. Inside the housing 20 is a data processing device 201 for processing signals received by the antenna unit 30. The data processing device 201 is electrically connected to the rotating device 10 via a conductive slip ring 40. A power supply unit (not shown) is electrically connected to the rotating device 10, and under the continuous and stable power output of the power supply unit, the rotating device 10 drives the housing 20 and the antenna unit 30 to rotate together. During electromagnetic environment testing, the operator only needs to start the rotating device 10 and the data processing device 201, and set parameters such as the operating frequency band, rotation angle, and operating time through the control terminal to achieve automatic rotation of the antenna unit 30 and automatic acquisition of electromagnetic wave signals, simplifying the operation process.

[0040] Preferably, the chassis 20 is a cylindrical chassis with dimensions of 30cm*30cm*7cm.

[0041] In this embodiment, the rotating device 10 includes a rotating table 101, inside which a worm gear transmission device is installed. One end of the worm gear transmission device is connected to a motor 103 via a coupling 102. The motor 103 is electrically connected to the housing 20, ensuring efficient power transmission and reducing energy loss. Furthermore, the rotating device 10 also includes a base 104, located below the rotating table 101. The base 104 and the rotating table 101 have a hollow structure, providing a wiring channel for transmitting power and control signals between the housing 20 and the motor 103.

[0042] Specifically, one end of the coupling 102 is connected to the shaft of the motor 103, and the other end is connected to the shaft of the rotary table 101.

[0043] In this embodiment, the directional antenna rotation control device further includes a control terminal (not shown in the figure), which can control and display the rotation angle of the rotation device 10. Furthermore, the control terminal is a tablet computer.

[0044] Specifically, the control accuracy of the rotating device 10 is 0.01 degrees. In traditional electromagnetic environment testing tasks, because the monitoring antenna is rotated manually, the rotation angle often fluctuates and the pointing is inaccurate during the actual rotation process, resulting in uneven test coverage and missed interference signals, causing test errors. The high-precision control of the antenna unit 30 enables the rotating device 10 to be accurately positioned to the required location, thereby ensuring the electromagnetic environment test coverage and the pointing accuracy of interference signals.

[0045] In this embodiment, the data processing device 201 includes a node server, a voltage conversion module, a serial port converter, a motor drive controller, a networking module, and a spectrum analyzer module, and the node server, voltage conversion module, serial port converter, motor drive, networking module, and spectrum analyzer module are electrically interconnected. Furthermore, in this embodiment, the node server is a card-type computer, which possesses all the functions and interfaces of a traditional computer and has low power consumption (this is prior art and will not be elaborated here).

[0046] Specifically, the spectrum analyzer module digitizes the electromagnetic wave signals received by the antenna unit 30 and outputs them to the node server. The node server is responsible for calculating and storing the digitized spectrum signals. The motor drive controller receives control commands from the node server and drives the motor 103 to achieve synchronous rotation between the rotating device 10 and the chassis 20. The voltage conversion module converts the externally input DC voltage into the operating voltage required for the internal modules and connects it to the corresponding modules. The networking module is a router that can build an internal local area network to achieve network connection between the control terminal and the node server. The serial port converter can perform protocol conversion from USB interface to 485 or 232 serial port, thereby enabling the node server to control the electronic compass 202 and the motor drive controller and transmit data.

[0047] The working principle of the control terminal to control the rotating device 10 to achieve high-precision rotation is as follows:

[0048] The operator sends the monitoring task from the control terminal to the data processing device 201. The node server in the data processing device 201 converts the received monitoring task into control signals, including parameters such as pulse count, running direction, and rotational angular velocity. These control signals are then sent to the motor drive controller via a serial port converter. The motor drive controller converts the received control signals into pulse signals and transmits them to the motor 103 through the power supply line and conductive slip ring 40. When the motor 103 rotates, each pulse rotates 1.8 degrees. The transmission ratio of the worm gear transmission device inside the rotary table 101 is 180:1, meaning that for every 180 degrees the motor 103 rotates, the rotary table 101 rotates 1 degree. Based on this ratio, a control accuracy of 0.01 degrees is achieved.

[0049] In this embodiment, the chassis 20 is divided into a first processing layer 204 and a second processing layer 205. The first processing layer 204 is equipped with a node server, a voltage conversion module, a serial port converter, a motor drive controller, and a networking module. The second processing layer 205 is equipped with a spectrum analyzer module. By dividing the chassis 20 into layers and integrating different functional modules, the complexity of the integrated design is reduced. The modular design allows each functional module to operate and be maintained independently, and it is easy to upgrade or replace according to specific needs. This design improves the flexibility and scalability of the system and can adapt to different working scenarios.

[0050] The chassis 20 has a wiring channel 206 inside, which allows the modules located in the first processing layer 204 to be electrically connected to the modules located in the second processing layer 205.

[0051] Compared to the traditional rotating device 10 which uses a radio frequency rotating joint, this embodiment integrates a data processing device 201 inside the chassis 20, which avoids connecting the collected radio frequency signals to the outside of the rotating device 10 for processing, reduces the number of radio frequency signal transmission nodes, and thus improves the stability and reliability of the entire system operation.

[0052] In this embodiment, the outer wall of the chassis 20 is provided with a hollow structure, which enables the chassis 20 to transfer internal heat to the outside air more effectively, thereby improving heat dissipation efficiency.

[0053] In this embodiment, the upper cover of the chassis 20 is equipped with an electronic compass 202 and an external Wi-Fi antenna 203. The antenna unit 30 is also mounted on the upper cover of the chassis 20. The azimuth direction of the electronic compass 202 and the antenna unit 30 are aligned. During the rotation of the rotating device 10, the azimuth information acquired by the electronic compass 202 is the azimuth information of the antenna unit 30. The operator can view the azimuth information collected by the electronic compass 202 on the control terminal. Simultaneously, the electronic compass 202 can be positioned due north, and in conjunction with the rotating device 10, the angle of the antenna unit 30 can be zeroed. The external Wi-Fi antenna 203 is the external antenna of the networking module, which can wirelessly transmit the signals received and processed by the data processing device 201 inside the chassis 20 to the control terminal.

[0054] In this embodiment, a conductive slip ring 40 is disposed between the chassis 20 and the rotating device 10. When the rotating device 10 rotates, the upper part of the conductive slip ring 40 moves with the rotating device 10, while the lower part of the conductive slip ring 40 remains stationary. Furthermore, a rotor 401 is provided at the upper end of the conductive slip ring 40, and a stator 402 is provided at the lower end of the conductive slip ring 40. When the rotor 401 rotates, the stator 402 maintains contact with the rotor 401 through elastic pressure. Current or signals are transmitted through the sliding contact point between the stator 402 and the rotor 401, forming a continuous path between the rotating device 10 and the data processing device 201.

[0055] Specifically, the conductive slip ring 40 ensures uninterrupted power supply and signal transmission when the data processing device 201 rotates, guaranteeing the continuity and integrity of data during rotation. The conductive slip ring 40 allows the rotating device 10 to rotate freely within a 360° range without being restricted by tangled wires, greatly improving the system's flexibility.

[0056] In this embodiment, a snap-fit ​​position is reserved at the bottom of the chassis 20, and the conductive slip ring 40 can be snapped into the lower cover plate of the chassis 20 through the rotor 401.

[0057] In this embodiment, the rotation control device further includes a support device 50, which is connected to the bottom of the rotation device 10. The support device 50 includes a flange 501 and a support frame 502 located below the flange 501, and the flange 501 is provided with a power supply connection port 5011.

[0058] Preferably, the support frame 502 is a tripod, and the load-bearing capacity of the tripod is within 30kg.

[0059] In this embodiment, an isolation column is provided between the bottom of the base 104 and the flange 501. Through the isolation column, space is left between the rotating device 10 and the flange 501 for cables to pass through, facilitating the laying of various power lines and control lines. The power supply unit is connected to the power supply connection port 5011, and then the power supply line passes through the hollow structure of the flange 501, the base 104, and the rotating table 101, and connects to the conductive slip ring 40. The power supply signal is divided into three paths by the conductive slip ring 40. The first path passes through the voltage conversion module in the data processing device 201, which converts the voltage to a suitable value for use by the internal modules of the chassis 20, such as the node server, networking module, and spectrum analyzer. The second path of the power supply signal is led out from the top cover of the chassis 20 for use by the antenna unit 30. The third path of the power supply signal and the control signal output by the motor drive controller are transmitted to the motor 103 through the conductive slip ring 40, completing the distribution and use of power supply and control signals.

[0060] Preferably, the power supply unit is a 12V 5A lithium battery module, and the voltage conversion module converts the DC voltage from 12V to 5V.

[0061] In other embodiments, the power supply is a 12V DC switching power supply.

[0062] In this embodiment, the base 104 is provided with an adapter 105 at the bottom. Through the adapter 105, the rotating device 10 can be installed on a tripod, a car luggage rack, or a drone pod, so that the system can adapt to different working environments.

[0063] The assembly and usage method of a directional antenna rotation control device provided in this embodiment is as follows:

[0064] S1. When using the device, first set up the tripod and install the flange 501 onto it. Next, assemble and install the rotating device 10, the housing 20, and the conductive slip ring 40. Then, fix the rotating device 10 to the flange 501 using the adapter 105 at the bottom of the rotating device 10. Finally, install the antenna unit 30 onto the housing 20, completing the overall setup of the tripod support platform. The two QMA interfaces provided on the top cover of the housing 20 are responsible for providing power and radio frequency signals to the antenna unit 30.

[0065] S2. After completing the connection between the power supply unit and power connection port 5011, turn on the power. The networking module and node server inside the chassis 20 will automatically power on and start. The node server is connected to the networking module via a wired connection and establishes an internal local area network. The control terminal joins the network wirelessly. After the operator connects to and logs into the node server via the control terminal, the data transmission channel between the control terminal and the node server is established.

[0066] S3. After setting up the rotation control device, calibrate the orientation information. The operator opens the "Directional Monitoring" App installed on the control terminal, enters the operation interface, and then selects the "Compass Zeroing" option in the interface. A voice broadcast will appear: "Compass zeroing, automatically adjust to true north." Then the system will rotate automatically and align the antenna unit 30 with true north.

[0067] S4. After completing the zeroing operation of antenna element 30, enter the "Settings" interface in the App software. Set basic parameters such as operating frequency band, duration, start and end angles, and rotation angles per turn to complete the editing of a monitoring task.

[0068] S5. After clicking "Task Monitoring," the control terminal sends the task parameters to the node server. The node server converts the task parameters into specific command signals, which are then sent to the motor drive controller via a serial port converter. The motor drive controller then drives the motor 103, the chassis 20, and the antenna unit 30 to rotate synchronously. Simultaneously, the node server receives electromagnetic wave signals collected by the spectrum analyzer and azimuth information collected by the electronic compass 202, and performs calculations and stores these information inside the chassis 20.

[0069] S6. After completing the monitoring task, the operator will download the monitoring data from the node server to the control terminal to view the spectrum information in each direction; the operator can also observe the spectrum in real time during the rotation.

They should not be construed as limiting the scope of protection of this utility model.
