Description

Technical Field

[0001] The present invention relates to the field of phased array technology and communication technology, and in particular to a low-cost, low-complexity, high-flexibility stationary target video transmission verification system for phased arrays. Background Art

[0002] In the field of modern communication technology, phased array technology is widely used in many important communication fields such as satellites and base stations due to its high flexibility and high performance. In the research and development process of phased array products, system communication performance testing is an indispensable link. Traditionally, phased array communication performance testing is reflected by indicators such as vector magnitude error (EVM), bit error rate (BER), and signal-to-noise ratio (SNR), but these indicators are often not intuitive enough and it is difficult to fully reflect the communication performance of phased arrays in practical applications. Therefore, high-quality real-time video transmission is often used as the most intuitive and effective solution for communication performance.

[0003] However, traditional phased array video transmission verification systems usually require developers to customize video modem hardware and software. This process is not only complex, but also time-consuming and labor-intensive, resulting in a long development cycle and high costs. In addition, custom-developed hardware and software are usually over-coupled with the phased array. Once the number of phased array interfaces or test requirements change, the system's adaptability and scalability will also be limited. Summary of the invention

[0038] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0039] The first embodiment of the present invention is a scheme for a millimeter wave phased array single-channel stationary target video transmission verification system. The second embodiment of the present invention is a scheme for a millimeter wave phased array dual-channel stationary target video transmission verification system. The third embodiment of the present invention is a scheme for a 2.4 GHz phased array single-channel stationary target video transmission verification system.

[0040] like Figure 1The figure is a principle block diagram of a demonstration scheme of a millimeter wave phased array single-channel video transmission system according to an embodiment of the present invention, including a baseband video transmission system and a phased array module. The baseband video transmission system is composed of a transmitting subsystem and a receiving subsystem. The transmitting subsystem is composed of a camera module, a baseband module, and an up / down conversion module; the receiving subsystem is composed of a display module, a baseband module, and an up / down conversion module.

[0041] Specifically, the size of the antenna array in the phased array module in the first embodiment of the embodiment of the present invention is 2*8, and it can operate at two frequencies of 28GHz and 39GHz, and has three operating modes of 28GHz narrowband, 39GHz narrowband, and 28 / 39GHz broadband, and each operating mode has two polarization directions, horizontal and vertical. The phased array module has two polarizations, vertical and horizontal. In the first embodiment of the embodiment of the present invention, the phased array module operates in a 28GHz horizontal polarization mode, and there is only one data transmission channel.

[0042] Specifically, the up-down conversion module in the first embodiment of the embodiment of the present invention has a local oscillator input interface, a radio frequency interface and an intermediate frequency interface.

[0043] Specifically, there are two optional solutions for the baseband module in the first embodiment of the present invention. Solution 1 uses a commercial video wireless transmission modulation and demodulation module. Solution 2 uses a microcomputer module and a commercial wireless network card.

[0044] When using solution 1, the camera module is a commercial camera with an RCA interface, which can convert the captured image into an analog signal and output it through the RCA interface; the commercial video wireless transmission modulation module has an RCA video input interface and a radio frequency output interface. The display module is a 7-inch display screen with an RCA interface, and the commercial video wireless reception demodulation module has a radio frequency input interface and an RCA video output interface.

[0045] At the transmitting end, the transmitting end of the phased array module operates in a transmitting mode and is controlled to generate a beam perpendicular to the array plane.

[0046] In the transmitting subsystem of the baseband video transmission system, the camera is connected to the commercial video wireless transmission modulation module through an RCA cable. The analog video signal output by the camera is modulated on a 2.44GHz carrier by the commercial video wireless transmission modulation module and output through the RF interface. The RF output interface is connected to the intermediate frequency input interface of the up-down conversion module through a coaxial cable. The up-down conversion module works in the transmitting mode, uses an external frequency source to output a 30.44GHz signal, and connects the output interface of the signal source to the local oscillator input interface of the up-down conversion module through a coaxial cable. The RF output interface of the up-down conversion module is connected to the RF input interface of the phased array module through a coaxial cable. The modulated video signal is up-converted to 28GHz and radiated into free space through the phased array module.

[0047] At the receiving end, the phased array module receiving end works in a receiving mode and is controlled to generate a beam perpendicular to the array plane.

[0048] In the receiving subsystem of the baseband video transmission system, the up and down conversion modules work in the receiving mode. The phased array module converts the electromagnetic waves in the free space into RF signals for output, and then down-converts them to output 2.44GHz intermediate frequency signals, which are then converted into analog video signals by the commercial video wireless receiving and demodulation module. The analog video signals are input to the display screen through the RCA connection line to realize the real-time transmission of the camera shooting images.

[0049] When using solution 2, the camera module is a commercial camera with a USB interface, the microcomputer is a Raspberry Pi 4B that can run the Linux operating system and has four USB input interfaces and an HDMI output interface, the display module is a display with an HDMI interface, and the commercial wireless network card is a driver-free wireless network card with a USB interface.

[0050] When using solution 2, the video sending program in the transmitting subsystem is written in Python, the OpenCV library is used to obtain the camera image connected to the microcomputer, and the Flask library is used to build the server. The user can access the server through the set IP address to obtain the video stream of the camera shooting image.

[0051] When using solution 2, the video receiving program in the transmitting subsystem is written in HTML language, and its function is to obtain the video stream of the transmitting subsystem server of the baseband video transmission system by inputting the IP address and display it on the page.

[0052] When using solution 2, the specific operation process of the embodiment of the present invention is as follows

[0053] S1. Make hardware connections and ensure that each module works properly.

[0054] S2. Control the commercial wireless network card in the transmitting subsystem of the baseband video transmission system to open a 2.4G hotspot.

[0055] S3. Control the commercial wireless network card in the receiving subsystem of the baseband video transmission system to connect to the hotspot signal opened in S2.

[0056] S4. Run the server video sending program in the transmitting subsystem of the baseband video transmission system.

[0057] S5. Run the video receiving program in the receiving subsystem of the baseband video transmission system and input the target IP address.

[0058] S6. The camera image is displayed on the display module.

[0059] like Figure 2 , which is a principle block diagram of a demonstration scheme of a millimeter wave phased array dual-channel video transmission system according to a second embodiment of an embodiment of the present invention.

[0060] In the second embodiment of the present invention, the phased array module operates in a 28 GHz horizontal and vertical dual-polarization mode. Different from the first embodiment, the second embodiment realizes a single-frequency dual-polarization dual-channel video transmission demonstration by increasing the number of baseband video transmission systems.

[0061] like Figure 3 , which is a principle block diagram of a demonstration scheme of a 2.4 GHz phased array single-channel video transmission system according to a third embodiment of the present invention.

[0062] The phased array module in the third embodiment is an 8*8 circularly polarized phased array operating in the 2.4 GHz frequency band. Different from the first and second embodiments, the operating frequency of the phased array module in the third embodiment is the same as the operating frequency of the baseband module, so there is no need for an up / down conversion module, and the baseband module is directly connected to the phased array module via a coaxial line.

[0063] It should also be noted that in the above three embodiments, for the baseband module, no matter which solution is selected, when the millimeter wave communication system does not exist, the baseband module in the baseband video transmission system is connected to an omnidirectional antenna in the 2.4GHz frequency band, and the baseband video transmission module can still work normally alone, that is, video transmission can be achieved.

[0064] The basic principles and main features of the present invention and the advantages of the present invention are shown and described above. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.

[0065] Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is therefore intended that all changes falling within the meaning and range of equivalent elements of the claims are included in the present invention.

[0066] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
