Description

Technical Field

[0001] This application relates to the field of antenna reconfiguration technology, and in particular to an antenna reconfiguration system, an antenna reconfiguration control method, an antenna reconfiguration control device, a computer device, and a storage medium. Background Technology

[0002] A phased array antenna consists of multiple antenna elements, and the radiation pattern shape is changed by controlling the feed phase of each antenna element. Individual antenna elements have low gain, but when these elements are arranged together according to certain rules to form a large array, higher antenna gain can be achieved.

[0003] Since the 1970s, microstrip line-fed microstrip array antennas have dominated array technology. This is because microstrip array antennas have many advantages: simple structure, easy to manufacture, small size, low cost, easy conformal to the mounting surface, easy to achieve multi-polarization or multi-frequency operation, and their feeding network can be well integrated with the microstrip antenna element on the same dielectric substrate, which is something that other types of array antennas cannot do.

[0004] However, the inventors discovered that microstrip antennas are overly dependent on the precision of manufacturing equipment, and dimensional deviations during production have a significant impact on the operating frequency of microstrip antennas, resulting in actual measurement results that differ greatly from simulation results and a yield that does not meet expectations. Summary of the Invention

[0014] In one embodiment, the directional antenna transmitting system includes:

[0015] A transmitting antenna, used to provide radio frequency signals at the same frequency as the array antenna;

[0016] The second robotic arm is mechanically connected to the transmitting antenna. The second robotic arm is used to move the transmitting antenna in order to transmit radio frequency signals in a directional manner to the target antenna unit.

[0017] In one embodiment, a first robotic arm is used to move the laser device and camera into the non-signal receiving area of ​​the array antenna when the directional antenna transmitting system transmits radio frequency signals to the target antenna unit.

[0018] In one embodiment, after each laser reconstruction of the target antenna unit by the laser device, the transmitting antenna retransmits the radio frequency signal to the target antenna unit, and when the test performance parameters of the target antenna unit reach the preset performance requirements, the second robotic arm drives the transmitting antenna to move in order to transmit radio frequency signals directionally to other antenna units to be tested.

[0019] In one embodiment, the antenna unit includes a parasitic patch, a dielectric substrate, and a main patch stacked sequentially from top to bottom. The projection of the parasitic patch onto the main patch falls within the area where the main patch is located, and the dielectric substrate covers the main patch. A laser device is used to perform laser reconstruction on the parasitic patch and the main patch under the dielectric substrate.

[0020] In one embodiment, a slot is formed in the area of ​​the medium plate where no parasitic patch is provided and the corresponding main patch is provided. The laser device performs laser reconstruction on the parasitic patch and the main patch at the positions corresponding to the slot.

[0021] In one embodiment, the first robotic arm is positioned closer to the array antenna than the second robotic arm.

[0022] In one embodiment, the camera is communicatively connected to a directional antenna transmitting system;

[0023] The camera is used to determine the positioning information of the antenna unit based on the captured images;

[0024] The directional antenna transmitting system is used to receive positioning information and correct the initial positioning information of the stored antenna elements based on the positioning information to obtain the position information of each antenna element.

[0025] Secondly, an antenna reconfiguration control method is provided, the method comprising:

[0027] When the test performance parameters of the target antenna unit do not meet the preset performance requirements, the camera captures an image, and based on the image captured by the camera and the position information of the target antenna unit, the laser device is moved to the location of the target antenna unit so that the laser device can perform laser reconstruction on the target antenna unit until the test performance parameters of the target antenna unit meet the preset performance requirements. The test performance parameters are the test performance parameters obtained when the antenna test system controls the target antenna unit to work.

[0028] In one embodiment, the method further includes:

[0029] When the directional antenna transmitting system transmits radio frequency signals to the target antenna unit, it causes the laser device and camera to be in the non-signal receiving area of ​​the array antenna.

[0030] Thirdly, an antenna reconfiguration control device is provided, comprising:

[0031] The target antenna element information acquisition module is used to acquire the position information and test performance parameters of the target antenna element; wherein, the position information is the position information recorded when the directional antenna transmission system provides the same frequency radio frequency signal to each antenna element in the array antenna under test in a time-division manner, and the target antenna element is the antenna element that is currently affected by the radio frequency signal;

[0032] The dead pixel reconstruction execution module is used to acquire images captured by the camera when the test performance parameters of the target antenna unit do not meet the preset performance requirements. Based on the images captured by the camera and the position information of the target antenna unit, the module moves the laser device to the location of the target antenna unit so that the laser device can perform laser reconstruction on the target antenna unit until the test performance parameters of the target antenna unit meet the preset performance requirements. The test performance parameters are the test performance parameters acquired when the antenna test system controls the target antenna unit to work.

[0033] Fourthly, a computer device is provided, including a memory and a processor, wherein the memory stores a computer program, and the processor executes the computer program to implement the steps of the antenna reconfiguration method described above.

[0035] The aforementioned antenna reconfiguration system, antenna reconfiguration control method, antenna reconfiguration control device, computer equipment, and storage medium have at least the following beneficial effects:

[0036] In this antenna reconfiguration system, the directional antenna transmission system can provide the same-frequency radio frequency signal to each antenna element in the array antenna under test in a time-division manner. That is, it can transmit a signal directionally to only one antenna element at a time and record the position information of that antenna element. The antenna test system controls the target antenna element affected by the current radio frequency signal and acquires the test performance parameters of the target antenna element. The first robotic arm is mechanically connected to the laser device and the camera, and is communicatively connected to the antenna test system, the directional antenna transmission system, the camera, and the laser device. The first robotic arm receives the position information of the target antenna element. Based on the communication between the first robotic arm and the antenna test system, it can determine whether the test performance parameters of the target antenna element meet the preset performance requirements. If the preset performance requirements are not met, the first robotic arm can move the laser device to the location of the target antenna element based on the image acquired by the camera and the position information of the target antenna element, so that the laser device can perform laser reconfiguration on the target antenna element until the test performance parameters of the target antenna element meet the preset performance requirements. It can perform online testing and reconstruction of each antenna element in the array antenna, so that the measured results of the reconstructed phased array antenna and other array antennas match the simulation results, compensate for the errors caused by the precision of the production equipment, improve the yield, and the efficiency of online testing and reconstruction is high. Compared with the manual repair of the entire antenna, it is more accurate and can avoid antenna damage caused in the antenna correction process. Attached Figure Description

[0045] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be more thorough and complete.

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

[0047] It is understood that the terms “first,” “second,” etc., used in this application may be used herein to describe various components, but these components are not limited by these terms. These terms are used only to distinguish the first component from another component.

[0048] It should be noted that when one element is considered to be "connected" to another element, it can be directly connected to the other element, or connected to the other element through an intermediary element.

[0049] It should be understood that the terms "comprising / including" or "having," etc., specify the presence of the stated features, wholes, steps, operations, components, parts, or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof. Meanwhile, the term "and / or" as used in this specification includes any and all combinations of the associated listed items.

[0050] The solution provided in this application embodiment can be applied to the online reconfiguration of array antennas, for example, phased array antennas. The independent units that make up the array antenna are called antenna elements 104.

[0051] In response to the problems pointed out in the background art, in one embodiment, such as Figures 1a-1f As shown, an antenna reconfiguration system is provided, including: a directional antenna transmitting system 10, an antenna testing system 20, a camera 30, a laser device 40, and a first robotic arm 50.

[0052] The directional antenna transmitting system 10 is used to provide radio frequency signals of the same frequency to each antenna element 104 in the array antenna 90 under test in a time-division manner, and to record the position information of each antenna element 104.

[0053] The directional antenna transmitting system 10 provides radio frequency (RF) signals of the same frequency to each antenna element 104 in the array antenna 90 under test in a time-division manner. This can be based on preset rules, such as each antenna element 104 having a number, and the RF signals can be provided to each antenna element 104 separately according to the pre-stored numbers. Of course, for the antenna elements 104 arranged in an array in the array antenna 90, a row scanning or column scanning method can also be used to transmit RF signals to each antenna element 104 in a time-division manner to provide a test environment for each antenna element 104. The rules for the directional antenna transmitting system 10 to implement time-division signal transmission are not constrained here and are not limited to the numbered, row scanning, or column scanning methods exemplified here.

[0054] The antenna test system 20 is used to connect to the array antenna 90, which includes multiple antenna elements 104. The antenna test system 20 is used to control the operation of the target antenna element 104 and to acquire the test performance parameters of the target antenna element 104. The target antenna element 104 is the antenna element 104 that is affected by the current radio frequency signal.

[0055] Antenna test system 20 refers to a system capable of providing test fixtures for array antenna 90, which can excite array antenna 90 as a receiving antenna to communicate with directional antenna transmitting system 10. For example, antenna test system 20 can, as Figure 2As shown, the device includes an RF control circuit 102 and multiple ports (not shown). The RF control circuit 102 provides excitation signals, and the multiple ports are connected to the RF control circuit 102 and the antenna elements 104 respectively. The RF control circuit 102 can selectively excite individual antenna elements 104 through the ports to perform performance testing on individual antenna elements 104. The RF control circuit 102 may include a baseband circuit and a local oscillator (LO), etc. Based on the interaction between its various circuit components, it can control the operating state of each antenna element 104 and provide it with excitation signals, enabling it to operate in a receiving state.

[0056] Camera 30 (shown in the figure as a relative positional relationship between camera 30 and the first robotic arm 50) is used to acquire images. Camera 30 may be used solely for capturing images, or it may have image processing capabilities to determine the position of antenna element 104 in the image and generate positioning information for antenna element 104. This positioning information can be used during the initialization phase to calibrate the initial positioning information in the directional antenna transmission system 10, or it can be applied to correct the movement path of laser device 40 during online reconstruction, enabling it to accurately reach the target antenna element.

[0057] A laser device 40 (shown in the figure as a relative positional relationship between the laser device 40 and the first robotic arm 50) is used to provide laser light. Depending on the required etching precision, laser devices 40 of varying costs can be selected. For example, for a dielectric substrate 2 with a thickness of 1 mm, a laser device 40 with matching precision can be chosen to avoid damage during the etching of the antenna element 104.

[0058] The first robotic arm 50 is mechanically connected to the laser device 40 and the camera 30, and is also communicatively connected to the antenna testing system 20, the directional antenna transmitting system 10, the camera 30, and the laser device 40. The laser device 40 and the camera 30 can be connected to the end effector of the first robotic arm 50 to more flexibly move them.

[0059] The first robotic arm 50, based on its communication connection with the antenna testing system 20 and the directional antenna transmitting system 10, can acquire the position information of the target antenna unit 104. When the test performance parameters of the target antenna unit 104 do not meet the preset performance requirements, the first robotic arm 50, based on the image acquired by the camera 30 and the position information of the target antenna unit 104, moves the laser device 40 to the location of the target antenna unit 104 (e.g., ...). Figure 1b , Figure 1c and Figure 1d As shown), so that the laser device 40 performs laser reconstruction on the target antenna element 104 (as shown). Figure 1e and Figure 1f (As shown), until the test performance parameters of the target antenna element 104 reach the preset performance requirements. The preset performance requirements can be determined based on the antenna design purpose; for example, simulation results that meet the design purpose can be used as preset performance requirements.

[0060] The first robotic arm 50 moves the laser device 40 to the location of the target antenna unit 104 based on the image captured by the camera 30 and the position information of the target antenna unit 104. This can be achieved by the camera 30 capturing images in real time and feeding them back to the first robotic arm 50. The first robotic arm 50 can change its posture based on the position information of the target antenna unit 104 to move the camera 30 and the laser device 40 toward the target antenna unit 104. During the movement, the first robotic arm 50 can also adjust the path to the target antenna unit 104 based on the images captured in real time by the camera 30 to ensure that the laser device 40 can accurately move to the position of the target antenna unit 104.

[0061] It should be noted that the first robotic arm 50 performs path planning to the target antenna unit 104 based on the position information of the target antenna unit 104 and the image captured by the camera 30. This can be achieved based on existing path planning algorithms and is not constrained here.

[0062] Specifically, the antenna reconfiguration system provided in this application allows the directional antenna transmitting system 10 to transmit signals directionally to only one antenna element 104 at a time and record the position information of that antenna element 104. Furthermore, the antenna testing system 20 cooperates with the directional antenna transmitting system 10 to control the target antenna element 104 affected by the current radio frequency signal and acquire the test performance parameters of the target antenna element 104. The first robotic arm 50 acquires the position information of the target antenna element 104. Based on the communication relationship between the first robotic arm 50 and the antenna testing system 20, the first robotic arm 50 can determine whether the test performance parameters of the target antenna element 104 meet the preset performance requirements. If the preset performance requirements are not met, the laser device 40 can be moved to the location of the target antenna element 104 based on the image captured by the camera 30 and the position information of the target antenna element 104, so that the laser device 40 performs laser reconfiguration on the target antenna element 104 until the test performance parameters of the target antenna element 104 meet the preset performance requirements. Online testing and reconstruction of each antenna element 104 in the array antenna 90 can be performed, ensuring that the measured results of the reconstructed phased array antenna 90 match the simulation results. This compensates for errors caused by the precision of production equipment, improves yield, and reduces economic losses. Furthermore, online reconstruction can further enhance antenna performance and reduce the precision requirements of PCB (Printed Circuit Board) production equipment, thus lowering equipment costs. In addition, online testing and reconstruction are highly efficient and more precise than manual antenna correction, preventing antenna damage during the correction process.

[0063] The determination that the test performance parameters of the target antenna element do not meet the preset performance requirements can be made by the antenna testing system 20 based on the test performance parameters of the target antenna element. Upon determining that the preset performance requirements are not met, a trigger signal is sent to the first robotic arm 50, notifying the first robotic arm 50 to reconstruct the target antenna element. In this method, the first robotic arm 50 is only triggered when the antenna testing system 20 determines that the test performance parameters of the target antenna element do not meet the preset performance requirements, thus reducing the computational resources of the first robotic arm 50. Alternatively, the antenna testing system 20 can send the test performance parameters of the target antenna element to the first robotic arm 50, and the first robotic arm 50 can then determine whether the preset performance requirements are met based on these parameters.

[0064] In one embodiment, the directional antenna transmitting system 10 includes a transmitting antenna 12 and a second robotic arm 14.

[0065] The transmitting antenna 12 is used to provide radio frequency signals at the same frequency as the array antenna 90. Here, the transmitting antenna 12 refers to an antenna capable of transmitting signals. It may have an embedded radio frequency chip to provide an excitation signal to excite the antenna body to radiate radio frequency signals in a directional manner.

[0066] The second robotic arm 14 is mechanically connected to the transmitting antenna 12. The second robotic arm 14 is used to drive the transmitting antenna 12 to move so as to transmit radio frequency signals in a directional manner to the target antenna unit 104.

[0067] Optionally, the transmitting antenna 12 can be located at the end of the second robotic arm 14 to provide more free end and movement space. Similar to the embodiments described above, the second robotic arm 14 can store rules for time-division multiplexing radio frequency signals to each antenna element 104, including but not limited to rules such as numbered order, row scanning, and column scanning.

[0068] Both the first robotic arm 50 and the second robotic arm 14 can include a base and a robotic arm on it, and both can be multi-degree-of-freedom robotic arms. The specific selection can be set according to the needs of the actual application scenario.

[0069] The target antenna element 104 refers to the antenna element 104 that the radio frequency signal is currently acting on, that is, the antenna element 104 that the radio frequency signal transmitted by the transmitting antenna 12 is aimed at.

[0070] By mounting a transmitting antenna 12 on the second robotic arm 14, radio frequency signals can be precisely and directionally transmitted to a single antenna unit 104, providing a testing environment for the antenna unit 104 and improving testing accuracy.

[0071] In one embodiment, the first robotic arm 50 is used to move the laser device 40 and the camera 30 into the non-signal receiving area of ​​the array antenna 90 when the directional antenna transmitting system 10 transmits radio frequency signals to the target antenna unit 104.

[0072] The non-signal receiving area refers to the area that does not affect the antenna element 104 of the array antenna 90 from receiving radio frequency signals transmitted from the directional antenna transmitting system 10.

[0073] Before transmitting radio frequency signals to the target antenna unit 104, the directional antenna transmitting system 10 can send a notification signal to the first robotic arm 50. When the first robotic arm 50 receives the notification signal, if it is in the signal receiving area of ​​the array antenna 90, it will move the laser device 40 and the camera 30 to the non-signal receiving area of ​​the array antenna 90. If it is not in the signal receiving area, it will keep the laser device 40 and the camera 30 in the non-signal receiving area to avoid blocking the target antenna unit 104 from receiving radio frequency signals (e.g., ...). Figure 1a (As shown).

[0074] It should be understood that each time the directional antenna transmitting system 10 transmits a radio frequency signal to the target antenna unit 104, the first robotic arm 50 moves the laser device 40 and the camera 30 to the non-signal receiving area of ​​the array antenna 90. For example, if the reconstruction modification of a single target antenna element 104 is not done once, after each laser reconstruction, the first robotic arm 50 moves the laser device 40 and the camera 30 to the non-signal receiving area of ​​the array antenna 90 so that the directional antenna transmitting system 10 can transmit radio frequency signals to the target antenna element 104 again and obtain new test performance parameters to determine whether the test results of the laser-reconstructed target antenna element 104 meet the preset performance requirements. If not, the first robotic arm 50 moves the laser device 40 to the location of the target antenna element 104 again and performs a second laser reconstruction on the target antenna element 104. After the second laser reconstruction, the first robotic arm 50 moves the laser device 40 and the camera 30 to the non-signal receiving area of ​​the array antenna 90 again, and the directional antenna transmitting system 10 transmits radio frequency signals to the target antenna element 104 again and obtains new test performance parameters. The above process can be repeated until the test performance parameters of the target antenna element 104 meet the preset performance requirements.

[0075] The laser device 40 performs laser reconstruction on the antenna element 104, which can be determined based on the test performance parameters of the target antenna element 104. For example, based on previous experience, different laser etching schemes can be pre-stored for different test performance parameters. Based on this mapping relationship, the laser device 40 can quickly determine the matching laser etching scheme based on the test performance parameters of the target antenna element 104, such as reconstruction schemes like drilling holes or chamfering on the main patch 3 and parasitic patch 1. The laser device 40 performs laser etching on the antenna element 104 according to the matching laser etching scheme. The laser device 40 may include a high-precision moving platform and a laser mounted on the high-precision moving platform. The high-precision moving platform can determine the laser etching path based on the laser etching scheme and drive the laser along the path to perform laser reconstruction. The laser can also acquire the laser etching path and determine the laser intensity at each point on the laser etching path according to the laser etching scheme. The laser is used to provide a laser intensity matching the point on the laser etching path.

[0076] Alternatively, the laser device 40 can perform laser reconstruction on the antenna element 104, and its movement along the laser etching path can also be achieved by the movement of the first robotic arm 50. The first robotic arm 50 can quickly determine the matching laser etching scheme based on the test performance parameters of the target antenna element 104, determine the laser etching path based on the laser etching scheme, and drive the laser along the laser etching path to perform laser reconstruction.

[0077] In one embodiment, after the laser device 40 completes each laser reconstruction of the target antenna unit 104, the transmitting antenna 12 retransmits a radio frequency signal to the target antenna unit 104. When the test performance parameters of the target antenna unit 104 meet the preset performance requirements, the second robotic arm 14 moves the transmitting antenna 12 to directionally transmit radio frequency signals to other antenna units 104 to be tested. The process of the second robotic arm 14 switching antenna units 104 can be triggered based on the test performance parameters of the target antenna unit 104 meeting the preset performance requirements. For example, the antenna testing system 20 can send the test performance parameters of the target antenna unit 104 to the second robotic arm 14. If the second robotic arm 14 determines that the test performance parameters of the target antenna unit 104 match its pre-stored preset performance requirements, it moves the transmitting antenna 12 to directionally transmit radio frequency signals to other antenna units 104 to be tested. The antenna testing system 20 can determine whether the test performance parameters of the target antenna unit 104 meet the preset performance requirements based on the test performance parameters. If the test performance parameters meet the preset performance requirements, the system will send a test pass signal to the second robotic arm 14. When the second robotic arm 14 receives the test pass signal, it will move the transmitting antenna 12 to transmit radio frequency signals to the other antenna units 104 to be tested.

[0078] The process of the second robotic arm 14 moving the transmitting antenna 12 can be achieved by driving the stepper motors at each joint of the robotic arm to change the pose of the second robotic arm 14. The change in the pose of the second robotic arm 14 will cause the pose of the transmitting antenna 12 to change, thereby changing the relative positional relationship between the transmitting antenna 12 and each antenna element 104 on the array antenna 90, so as to realize the directional transmission of radio frequency signals to different antenna elements 104.

[0079] In one embodiment, the antenna unit 104 includes a parasitic patch 1, a dielectric substrate 2, and a main patch 3 stacked sequentially from top to bottom. The projection of the parasitic patch 1 onto the main patch 3 falls within the area where the main patch 3 is located, and the dielectric substrate 2 covers the main patch 3. The laser device 40 is used to perform laser reconstruction on the parasitic patch 1 and the main patch 3 under the dielectric substrate 2.

[0080] The laser device 40 performs laser reconstruction on the parasitic patch 1 and the main patch 3 under the dielectric substrate 2. Referring to the description in the above embodiments, when the laser device 40 includes a high-precision moving platform and a laser mounted on the high-precision moving platform, the high-precision moving platform can determine the laser etching path based on the laser etching scheme, and drive the laser along the laser etching path to perform laser reconstruction. Alternatively, the etching path can be determined based on the movement control function of the first robotic arm 50. The laser device 40 is used for laser reconstruction of the parasitic patch 1 and the main patch 3 under the dielectric substrate 2. The laser reconstruction settings for the parasitic patch 1 and the main patch 3 under the dielectric substrate 2 involve performing laser reconstruction on at least one of them.

[0081] The laser etching path can include laser etching paths for parasitic patch 1, dielectric substrate 2, and main patch 3. For example, when the antenna element 104 results in... Figure 3 As shown, the dielectric substrate 2 covers the main patch 3, and the parasitic patch 1 is disposed on the dielectric substrate 2. A ground layer 4 is disposed below the main patch 3, and power is supplied through the power supply position 31. An SPI (Serial Peripheral Interface) line 5 can be disposed below the ground layer to connect to external circuits such as the RF control circuit 102 through the power supply network 6.

[0082] To perform laser reconstruction on the main patch 3, the dielectric substrate 2 needs to be etched first to expose the area of ​​the main patch 3 that needs to be reconstructed. Of course, when the dielectric substrate 2 is a glass plate, laser reconstruction of the main patch 3 can be performed without damaging the dielectric substrate 2. For example, as... Figure 3 As shown, the parasitic patch 1 can be printed on the top surface of the glass plate.

[0083] The above-mentioned reconstruction can also be performed only on the main patch 3 using laser reconstruction.

[0084] In one embodiment, a slot 21 is formed in the area of ​​the dielectric substrate 2 where no parasitic patch 1 is provided and corresponding to the main patch 3. The laser device 40 performs laser reconstruction on the parasitic patch 1 and the main patch 3 at positions corresponding to the slot 21. The slot can be pre-set in advance in the area of ​​the main patch 3 on the antenna device used for laser reconstruction, i.e., as shown... Figure 4 As shown, a slot 21 is opened on the dielectric substrate 2 at the corresponding position, so that the main patch 3 is partially exposed. During laser reconstruction, the laser equipment 40 can directly perform laser reconstruction on the position corresponding to the slot 21.

[0085] In one embodiment, the first robotic arm 50 is used to determine the path for the laser device 40 to move to the slot 21 based on the image captured by the camera 30, and to move the laser device 40 along the path so that the laser device 40 performs laser reconstruction of the main patch 3 at the position of the slot 21. Optionally, slots 21 can be cut on multiple surfaces of the dielectric substrate 2.

[0086] In one embodiment, the first robotic arm 50 is positioned closer to the array antenna 90 than the second robotic arm 14. To further improve online reconfiguration efficiency, the first robotic arm 50 can be positioned closer to the array antenna 90 to reduce the time the laser device 40 spends moving along the laser etching path. This is especially beneficial for situations where a single antenna element 104 may require multiple laser reconfigurations; this positioning can significantly improve reconfiguration efficiency.

[0087] In one embodiment, the camera 30 is communicatively connected to the directional antenna transmitting system 10. The camera 30 is used to determine the positioning information of the antenna elements based on the acquired images; the directional antenna transmitting system 10 is used to receive the positioning information and correct the stored initial positioning information of the antenna elements based on the positioning information to obtain the position information of each antenna element.

[0088] The initial positioning information of the antenna elements 104 stored in the directional antenna transmitting system 10 can be determined based on the relative positions between multiple positioning points on the test fixture of the directional antenna transmitting system 10 and the antenna test system 20. For example, when the antenna test system 20 includes a fixture and a base, multiple positioning points can be marked on the fixture and / or the base. Based on laser positioning or image acquisition, the initial positioning information of each antenna element 104 under the standard installation position of the array antenna under test can be determined. However, considering that during the installation of the array antenna 90, the actual installation position of the array antenna 90 may deviate from the standard installation position under the test fixture due to human installation deviations, resulting in inaccurate initial positioning information of the antenna elements 104, the positioning information of the antenna elements generated by the camera 30 based on image acquisition can be obtained before online testing and reconstruction of the array antenna 90, and then the initial positioning information can be corrected based on this positioning information. If the positioning information and the initial positioning information are in the same coordinate system, the directional antenna transmitting system 10 can directly correct the initial positioning information by adjusting the deviation between the positioning information of the antenna element determined by the camera 30 and the initial positioning information, in the case of inconsistency between the two, to determine the latest position information. If the positioning information and the initial positioning information are not in the same coordinate system, the directional antenna transmitting system 10 can first transform the positioning information determined by the camera 30 to the coordinate system of the directional antenna transmitting system 10 based on the coordinate system transformation relationship between itself and the camera 30, and then compare it with the stored initial positioning information. If the two are inconsistent, the initial positioning information can be corrected based on the deviation between the two. The camera 30 can determine the positioning information of only one antenna element 104, and compare the positioning information of that antenna element 104 in the initial positioning information with it individually to determine whether the initial positioning information of all antenna elements 104 needs to be corrected, reducing the amount of computation. Of course, the camera 30 can also determine the positioning information of multiple antenna elements 104 to improve accuracy. If the positioning information of the antenna element 104 determined by the camera 30 is consistent with the initial positioning information, this correction action is not required.

[0089] The antenna reconfiguration system provided in this application embodiment can first place the array antenna 90 under test as a receiving antenna on the antenna testing system 20, and control it to operate only one antenna element 104 at a time. Then, the camera 30 on the first robotic arm 50 is used to confirm the position of the working antenna element 104. The second robotic arm 14 is used to align with the antenna element 104 to be tested (i.e., the antenna element 104 in the working state), test the performance of the antenna element 104, and record the position information and feed it back to the first robotic arm 50. When the performance of the antenna element 104 meets the requirements, the next antenna element 104 is tested. When the performance of the antenna element 104 does not meet the preset performance requirements, the laser device 40 on the first robotic arm 50 starts working to perform reconfiguration such as edge trimming and hole drilling. After one modification, the first robotic arm 50 leaves and moves to the non-signal receiving area of ​​the array antenna 90, and the second robotic arm 14 performs the test. This test-reconfiguration-test process is repeated multiple times until the test performance parameters meet the predetermined performance requirements, at which point the first robotic arm 50, the second robotic arm 14, and the laser device 40 stop working. After all antenna elements 104 have been tested, all parts of the antenna reconfiguration system described above can be stopped from operating.

[0090] The antenna element 104 described above can be a patch antenna element 104.

[0091] Based on the same concept, in one embodiment, an antenna reconfiguration control method is provided, such as... Figure 5 As shown, the method includes:

[0092] S502, acquire the position information of the target antenna element; wherein, the position information is the position information recorded when the directional antenna transmitting system provides the same frequency radio frequency signal to each antenna element in the array antenna under test in a time-division manner; the target antenna element is the antenna element that the current radio frequency signal is acting on;

[0093] S504: When the test performance parameters of the target antenna unit do not meet the preset performance requirements, the system acquires the image captured by the camera and moves the laser device to the location of the target antenna unit based on the image captured by the camera and the position information of the target antenna unit, so that the laser device can perform laser reconstruction on the target antenna unit until the test performance parameters of the target antenna unit meet the preset performance requirements. The test performance parameters are the test performance parameters acquired when the antenna test system controls the target antenna unit to work.

[0094] The definitions of terms such as preset performance requirements can be found in the descriptions of the above system embodiments and will not be repeated here. The implementation process of this method can be understood by substituting the execution entity of the first robotic arm in the above embodiments. However, it should be understood that the execution entity of this method can also be a separate controller. This controller can communicate with the controller in the first robotic arm to control the first robotic arm to perform the working process described in the above system embodiments, thereby realizing online testing and laser reconstruction of the array antenna. This ensures antenna performance, reduces the requirements for PCB production equipment, and lowers costs. It also avoids antenna damage caused by manual correction methods.

[0095] In one embodiment, the method further includes:

[0096] When the directional antenna transmitting system transmits radio frequency signals to the target antenna unit, it causes the laser device and camera to be in the non-signal receiving area of ​​the array antenna.

[0097] As described in the above embodiments, when the directional antenna transmitting system transmits radio frequency signals to the target antenna unit, the laser device and camera are always kept in the non-signal receiving area of ​​the array antenna to avoid blocking the radio frequency signals, which would cause the test performance parameters of the antenna unit to become abnormal due to the blockage and result in misjudgment.

[0098] This application also provides an antenna reconfiguration control method, which may include some or all of the steps in the second manipulator's operation process in the above system embodiments, so as to achieve corresponding beneficial effects.

[0099] In one embodiment, an antenna reconfiguration control method is also provided, which may include some or all of the steps in the antenna test system implementation process described in the above system embodiment, in order to achieve the corresponding beneficial effects.

[0100] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.

[0101] Based on the same inventive concept, this application also provides an antenna reconfiguration control device for implementing the antenna reconfiguration control method described above.

[0103] The target antenna element information acquisition module 602 acquires the location information of the target antenna element and sends it to the bad pixel reconstruction execution module 604. When the test performance parameters of the target antenna element do not meet the preset performance requirements, the bad pixel reconstruction execution module 604 acquires an image from a camera and, based on the image and the location information of the target antenna element, moves a laser device to the location of the target antenna element to perform laser reconstruction until the test performance parameters of the target antenna element meet the preset performance requirements. This allows for online testing and reconstruction of each antenna element in the array antenna, ensuring that the measured results of the reconstructed phased array antenna match the simulation results. This compensates for errors caused by the precision of the production equipment, improves the yield, and offers high efficiency in online testing and reconstruction. Compared to manual antenna correction, it is more accurate and avoids antenna damage caused during the antenna correction process.
