Description

Technical Field

[0001] This invention belongs to the field of communication testing technology, specifically relating to a multi-polarization antenna testing control system, method, and storage medium. Background Technology

[0002] Existing multi-polarization antenna testing systems include a vector network analyzer whose first, second, and fourth ports are connected to three auxiliary antennas (a second, first, and third auxiliary antenna) via microwave cables. These auxiliary antennas are placed on a first, second, and third polarization turntable, respectively. The third port of the vector network analyzer is connected to the antenna under test (AUT) via a microwave cable, and the AUT is fixedly placed on its support. Depending on the different polarization scattering characteristics of the AUT, the first, second, and third polarization turntables can be selected to perform various polarization RCS tests.

[0003] However, in actual testing, due to the different shapes of the auxiliary antennas, their stability also varies. When placed on the polarization turntable, it cannot be guaranteed that all auxiliary antennas can be fixedly adapted to the polarization turntable. When the polarization turntable rotates, if the corresponding auxiliary antennas slide or roll due to poor stability, the test results will be unreliable.

[0004] Therefore, at this stage, it is necessary to design a multi-polarization antenna test and control system, method, and storage medium to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-polarization antenna test control method, system, and storage medium to solve the technical problems existing in the prior art, such as: the auxiliary antennas have different shapes, resulting in differences in stability. When placed on the polarization turntable, it cannot be guaranteed that all auxiliary antennas can be fixedly adapted to the polarization turntable. When the polarization turntable rotates, if the corresponding auxiliary antennas slide or roll due to poor stability, the test results will be unreliable.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows:

[0007] The multi-polarization antenna test and control system includes a rotation speed detection device, a pressure detection device, a displacement detection device, an image detection device, a reset and adjustment device, and a main control device.

[0008] The main control device is connected to the speed detection device, pressure detection device, displacement detection device, image detection device, and reset adjustment device respectively;

[0009] The speed detection device is used to detect the real-time speed of each polarization turntable and determine whether the real-time speed has reached the warning speed.

[0010] The pressure detection device is used to detect whether the pressure data on the turntable has changed;

[0011] The displacement detection device is used to detect whether the auxiliary antenna has shifted on the polarization turntable;

[0012] The image detection device is used to acquire image data of the auxiliary antenna after it has been displaced on the polarization turntable, and to determine whether the auxiliary antenna is still within the resettable range based on the image data.

[0013] The reset adjustment device is used to reset the auxiliary antenna that has been displaced.

[0014] Furthermore, the main control device controls the speed detection device to be normally open, and controls the pressure detection device, displacement detection device, image detection device, and reset adjustment device to be normally closed;

[0015] When the speed detection device determines that the real-time speed has reached the warning speed, the main control device controls the pressure detection device to turn on.

[0016] When the pressure detection device detects a change in the pressure data on the turntable, the main control device controls the displacement detection device to turn on.

[0017] When the displacement detection device detects that the auxiliary antenna has shifted on the polarization turntable, the main control device controls the image detection device to turn on.

[0018] When the image detection device determines that the auxiliary antenna is still within the resettable range based on the image data, the main control device controls the reset adjustment device to start.

[0019] Furthermore, the speed detection device is a speed sensor.

[0020] Furthermore, the pressure detection device is a pressure sensor matrix fixedly installed on the turntable.

[0021] Furthermore, the displacement detection device is a displacement sensor.

[0022] Furthermore, the image detection device is a high-definition camera.

[0023] Furthermore, this also includes wireless communication devices and mobile terminals;

[0024] The main control device is connected to the mobile terminal network via the wireless communication device.

[0025] The test control method for multi-polarized antennas employs the multi-polarized antenna test control system described above for test control of multi-polarized antennas.

[0026] A storage medium storing a computer program, which, when run, executes the multi-polarized antenna test control method described above.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] The design incorporates a rotational speed detection device, a pressure detection device, a displacement detection device, an image detection device, and a reset adjustment device. This allows for timely detection of slippage or rolling of the auxiliary antenna due to instability, and automatic reset via the reset adjustment device in case of displacement. The coordinated operation of these devices prevents prolonged periods of inactive operation and avoids excessive data collection. Furthermore, the detection results from one device trigger the next, creating a seamless and reliable detection process. Attached Figure Description

[0044] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention; that is, the described embodiments are merely some embodiments of the invention, and not all embodiments. The components of the embodiments of the invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0045] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention. It should be noted that relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0046] Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0047] like Figure 1 As shown, a multi-polarization antenna test and control system is proposed, including a rotation speed detection device, a pressure detection device, a displacement detection device, an image detection device, a reset and adjustment device, and a main control device.

[0048] The main control device is connected to the speed detection device, pressure detection device, displacement detection device, image detection device, and reset adjustment device respectively;

[0049] The speed detection device is used to detect the real-time speed of each polarization turntable and determine whether the real-time speed has reached the warning speed.

[0050] The pressure detection device is used to detect whether the pressure data on the turntable has changed;

[0051] The displacement detection device is used to detect whether the auxiliary antenna has shifted on the polarization turntable;

[0052] The image detection device is used to acquire image data of the auxiliary antenna after it has been displaced on the polarization turntable, and to determine whether the auxiliary antenna is still within the resettable range based on the image data.

[0053] The reset adjustment device is used to reset the auxiliary antenna that has been displaced.

[0054] The above scheme includes a rotation speed detection device, a pressure detection device, a displacement detection device, an image detection device, and a reset adjustment device. These devices can detect in a timely manner phenomena such as slippage and rolling of the auxiliary antenna due to poor stability. Furthermore, when displacement occurs, the reset adjustment device can automatically reset the antenna.

[0055] Furthermore, such as Figure 2 As shown, the main control device controls the speed detection device to be normally open, and controls the pressure detection device, displacement detection device, image detection device, and reset adjustment device to be normally closed;

[0056] When the speed detection device determines that the real-time speed has reached the warning speed, the main control device controls the pressure detection device to turn on.

[0057] When the pressure detection device detects a change in the pressure data on the turntable, the main control device controls the displacement detection device to turn on.

[0058] When the displacement detection device detects that the auxiliary antenna has shifted on the polarization turntable, the main control device controls the image detection device to turn on.

[0059] When the image detection device determines that the auxiliary antenna is still within the resettable range based on the image data, the main control device controls the reset adjustment device to start.

[0060] In the above scheme, the orderly coordination and activation of the speed detection device, pressure detection device, displacement detection device, image detection device, and reset adjustment device can avoid too many detection devices being in an inactive state for a long time, and also avoid excessive invalid data collection. Simultaneously, the detection result of one detection device triggers the next detection device, creating a linked and one-to-one correspondence, making the detection effect more reliable.

[0061] Furthermore, the speed detection device is a speed sensor.

[0062] Furthermore, the pressure detection device is a pressure sensor matrix fixedly installed on the turntable.

[0063] Furthermore, the displacement detection device is a displacement sensor.

[0064] Furthermore, the image detection device is a high-definition camera.

[0065] Furthermore, such as Figure 3 As shown, it also includes wireless communication devices and mobile terminals;

[0066] The main control device is connected to the mobile terminal network via the wireless communication device.

[0067] The test control method for multi-polarized antennas employs the multi-polarized antenna test control system described above for test control of multi-polarized antennas.

[0068] A storage medium storing a computer program, which, when run, executes the multi-polarized antenna test control method described above.

[0069] A multi-polarization (linear, right-hand circular, and left-hand circular) microstrip antenna with a center frequency of 9 GHz can be tested and controlled using the aforementioned multi-polarization antenna test and control system. Its operating bandwidth is 5%. The antenna mainly consists of the following parts;

[0070] The antenna substrate is selected based on a combination of factors, including the center frequency and antenna size requirements. Since the antenna designed in this scheme has a high center frequency and a small size, polytetrafluoroethylene (PTFE) is used, with a relative permittivity of 2.65 and a thickness of h = 3 mm (mainly related to bandwidth requirements). The length and width of the antenna substrate are both 23 mm.

[0071] The center frequency resonant microstrip metal patch has a rectangular patch size of L = 7.9 mm related to the center frequency.

[0072] Polarization tuning metal patch stubs, two tuning stubs are rectangular metal patches of 4mm*1mm.

[0073] The PIN diode controls the on / off state of the three polarization tuning stubs, thereby controlling the antenna polarization.

[0074] Radio frequency coaxial feed head, used for antenna feeding.

[0075] Among these factors, the selection of antenna substrate is crucial. Polytetrafluoroethylene (PTFE) materials have a low dielectric constant and are relatively inexpensive, making them easy to miniaturize for high-frequency applications.

[0076] Multipolarization can be achieved by controlling the on / off state of the PIN diode. Three polarization modes, namely left-handed, right-handed, and linear polarization, can be realized, and the axial ratio and axial ratio bandwidth are good when circularly polarized.

[0077] High gain. The antenna gain for all three polarization modes is around 7 dBi, resulting in good antenna radiation performance.

[0079] Left-hand circular polarization

At this resonant frequency, S 11 With a return loss of less than -10dB and a bandwidth of less than -15dB, the antenna's return loss is approximately 1.4GHz. Simulation data for the antenna's reflection coefficient curve in left-hand circular polarization is shown below. Figure 4 As shown.

[0083] (3) Axis ratio

[0084] At the center frequency f0 = 9 GHz, the antenna axial ratio AR = 2.3 dB, and the bandwidth is approximately 500 MHz when the axial ratio is less than 3 dB. Simulation data for the axial ratio curve of the antenna in left-hand rotation is as follows: Figure 6 As shown.

[0085] (4) 3D diagram (antenna gain greater than 7 dBi) as shown Figure 7 As shown.

[0086] Right-hand circular polarization

[0087] (1) Return loss

[0088] The circular polarization center frequency of the reconfigurable microstrip antenna is f0 = 9 GHz. At this resonant frequency, S 11 With a return loss of less than -10dB and a bandwidth of less than -14dB, the antenna's return loss is approximately 1.4GHz. Simulation data for the antenna's reflection coefficient curve in left-hand circular polarization is shown below. Figure 8 As shown.

[0089] (2) 2D orientation pattern as shown Figure 9 As shown.

[0090] (3) Axis ratio

[0091] At the center frequency f0 = 9 GHz, the antenna axial ratio AR = 2.3 dB, and the bandwidth is approximately 500 MHz when the axial ratio is less than 3 dB. Simulation data for the axial ratio curve of the antenna in right-hand rotation is as follows: Figure 10 As shown.

[0093] linear polarization

[0094] (1) Return loss, such as Figure 12 As shown.

[0095] Through S 11 It can be seen that the 9GHz frequency is the resonant frequency of the antenna. At the resonant frequency, the return loss is -5.67dB. The operating frequency with a return loss of less than -5dB is 8.15~9.75GHz, and the bandwidth is 1.6GHz.

[0096] (2) 2D orientation pattern as shown Figure 13 As shown.

[0097] (3) Axis ratio

[0098] At a center frequency of 9 GHz, the antenna has an axial ratio greater than 50 dB. In the 8-10 GHz range, the value is significantly greater than 40 dB, indicating that the antenna is operating in a linearly polarized state at this time.
