Description

Technical Field

[0002] As a key component of airborne equipment, the command transponder is primarily used to receive information from ground stations and parse and package it for transmission to other airborne equipment to achieve guidance functions. Simultaneously, the response signals it sends to ground stations enable ground stations to track and monitor airborne equipment, making it of significant application value in aerospace and other fields.

[0003] Traditional command transponders generally adopt a discrete component design with a fixed system architecture, and realize signal reception, parsing and response functions through the combination of discrete components.

[0004] However, traditional command transponders, due to their discrete component design, result in a bulky system structure and large size, making it difficult to meet the requirements for device miniaturization and occupying significant space resources. Furthermore, their fixed system architecture and limited functionality prevent them from flexibly adapting to diverse scenario needs and offer poor functional expansion capabilities. Additionally, traditional command transponders have high power consumption and, due to their low operating frequency, are susceptible to interference from complex electromagnetic environments. Their complex interfaces also increase the risk of system failure and reduce operational stability. Utility Model Content

[0025] Next, refer to Figures 1-5 The structure of the command response device is described.

[0026] The command response device includes a printed circuit board 1 and a housing 2. The printed circuit board 1 integrates a control module 10, a conversion module 20, a frequency conversion module 30, a transceiver module 40, and a connection module 50.

[0028] Optionally, the connection module 50 may include a flexible printed circuit board connector (FPC), which has a large number of pins, is small in size, lightweight, and easy to connect and install. The housing 2 may be made of high-strength and lightweight aluminum alloy AL-7075 to reduce the weight of the command response device.

[0029] Based on this highly integrated structure, the printed circuit board can be very small in size, for example... Figure 1 and Figure 2 In the diagram, the green area represents the circuit board area of ​​printed circuit board 1, which integrates control module 10, conversion module 20, frequency conversion module 30, and transceiver module 40. This area can be circular or square, with the specific shape determined based on design requirements. The yellow area includes connection module 50, used to connect modules in the circuit board area to external modules. A housing 2 is installed outside the green area to protect each module.

[0030] The connecting module 50 penetrates the housing 2. The diameter of the housing 2 is 58.3 mm. Further, as... Figure 3 as well as Figure 4 As shown, the diameter of the housing 2 of the command response device is 58.3 mm. At the point where the connecting module 50 extends out of the housing 2, the housing 2 has a recessed chamfer design. The chamfer radius of the outer chamfer is 2.2 mm, and the chamfer radius of the inner chamfer is 0.5 mm. The furthest horizontal distance between the concave surface and the housing 2 is 51.65 mm. Figure 4 As shown, the housing 2 is 9 mm thick, the recess where the connecting module 50 is located is 8 mm wide, the outer chamfer is 3 mm thick, and the inner chamfer is 1 mm thick. Based on the above design, the command response device weighs less than 65 grams, and its volume, thickness, and weight are much smaller than those of existing command transponders, meeting the miniaturization requirements.

[0031] Optionally, the first control terminal of the control module 10 is connected to the control terminal of the conversion module 20, the second control terminal of the control module 10 is connected to the control terminal of the frequency converter module 30, and the third control terminal of the control module 10 is connected to the control terminal of the transceiver module 40.

[0032] Optionally, the control module 10 may include a field-programmable gate array (FPGA) chip to implement signal processing.

[0033] Optionally, the transmitting end of the conversion module 20 is connected to the transmitting end of the frequency conversion module 30, the first receiving end of the conversion module 20 is connected to the first receiving end of the frequency conversion module 30, the second receiving end of the conversion module 20 is connected to the second receiving end of the frequency conversion module 30, and the third receiving end of the conversion module 20 is connected to the third receiving end of the frequency conversion module 30. The conversion module 20 is used to perform analog-to-digital or digital-to-analog conversion on the received signal.

[0034] Optionally, the conversion module 20 may include a radio frequency agile transceiver, such as the AD9361 chip. This chip operates in the 70 MHz to 6.0 GHz frequency band, covering a wide range from low to high frequencies, and has a 6 GHz wideband frequency hopping range. Its baseband bandwidth is much greater than the 2 GHz communication bandwidth requirement, making it suitable for scenarios such as 5G, 6G, radar, and satellite communications. Furthermore, based on its rapid frequency hopping capability, it can respond to interference in specific frequency bands in the environment through fast frequency modulation communication, resisting external electromagnetic interference.

[0035] The AD9361 chip boasts strong programmability and broadband capabilities, integrating RF signal processing, flexible mixed-signal baseband processing, and frequency synthesis capabilities. It provides a configurable digital interface for the control module 10, simplifying the design. Furthermore, the highly integrated AD9361 chip replaces the traditional analog-to-digital converter, digital-to-analog converter, and filtering circuits built with discrete baseband devices, resulting in a simple design and low power consumption. In this embodiment, the overall power consumption is less than 9 watts.

[0036] As an optional implementation, the conversion module 20 includes an RF agile transceiver and multiple baluns, each balun being used to connect to the interfaces in the RF agile transceiver and the transmitter, first receiver, second receiver and third receiver of the frequency conversion module 30.

[0037] Optionally, the transceiver terminals of the frequency conversion module 30 and the transceiver terminals of the transceiver module 40 are connected. The frequency conversion module 30 is used to perform frequency conversion processing on the received signal according to a preset frequency multiplication factor. At least one antenna terminal of the transceiver module 40 is used to connect an antenna and transmit and receive analog signals through the antenna.

[0038] Optionally, the frequency converter module 30 may include a Ka-band channel chip, which may include at least one receiving path and at least one transmitting path. The receiving path may perform down-conversion processing on the received signal, and the transmitting path may perform up-conversion processing on the received signal. In addition, the frequency converter module 30 may also perform filtering and other processing on the received signal.

[0039] Optionally, the transceiver module 40 is used to amplify the power of the received signal and perform transceiver processing.

[0040] Optionally, the frequency converter module 30 and the transceiver module 40 can be connected via a microstrip line group. The microstrip line group includes multiple microstrip lines, the number of which can be determined according to the actual design. For example, if the frequency converter module 30 has three paths for transmitting signals to the transceiver module 40, then the microstrip line group includes three microstrip lines.

[0041] Optionally, the connection module 50 may be an interface integrated circuit (interface IC), which is responsible for the physical layer transmission and reception of the RS-422 protocol, converting the parallel / digital signals output by the control module 10 into differential signals of the RS-422 standard, so as to realize long-distance, interference-resistant data communication.

[0042] Optionally, the command response device further includes a storage module 60, one end of which is connected to the control module 10 and is used to store the FPGA configuration program. When the system is powered on, the FPGA loads the configuration file from the storage module 60 and determines its own logic function.

[0043] Optionally, the command response device further includes a crystal oscillator module, the first and second terminals of which are connected to the crystal oscillator terminals of the conversion module 20 and the frequency conversion module 30, respectively. The crystal oscillator module may be a 50 MHz crystal oscillator, used to provide clock synchronization information to the conversion module 20 and the frequency conversion module 30.

[0044] Based on the structure of the above-mentioned command response device, the process of receiving the target signal sent by the ground station, parsing and packaging it, and then sending the generated feedback signal to the target airborne equipment will be described next.

[0045] The specific process of receiving, parsing, and packaging the target signal sent by the ground station, and then generating the feedback signal is as follows: The transceiver module 40 in the command response device is connected to at least one antenna. The antenna is used to receive target signals sent by the ground station. The target signal can be an analog electrical signal obtained by processing radar pulses or radio signals. The signal can contain command information, feedback information and / or response information, etc. This embodiment does not impose any limitations.

[0046] After receiving the target signal, at least one antenna transmits it to the transceiver module 40. The transceiver module 40 receives the target signal transmitted by each antenna, performs power division and phase shifting on the target signal, and controls the output of the signal through a switch.

[0047] When the switch controlling the receiving path is turned on, the transceiver module 40 sends the processed signal to the frequency converter module 30. Upon receiving the processed signal, the frequency converter module 30 down-converts the signal to obtain the first frequency-converted signal. Specifically, the frequency converter module 30 can multiply the processed signal based on the local oscillator signal; the multiplication factor can be preset or set via the control module 10. The local oscillator signal can be an internal local oscillator signal generated by the frequency converter module 30 or a received external local oscillator signal. After frequency conversion, the frequency converter module 30 sends the first frequency-converted signal to the conversion module 20.

[0048] After receiving the first frequency-converted signal, the conversion module 20 performs analog-to-digital conversion and down-conversion on the first frequency-converted signal to obtain a low-frequency digital signal. The conversion module 20 then sends the low-frequency digital signal to the control module 10.

[0049] As an optional implementation, after receiving the low-frequency digital signal, the control module 10 decodes and verifies the low-frequency digital signal to determine whether the low-frequency digital signal is a valid signal. If so, a feedback signal is generated based on the low-frequency digital signal.

[0050] For example, the decoding circuit in the control module 10 can parse the encoded information in the low-frequency digital signal, such as pulse width, frequency, modulation method, etc., and compare the encoded information with a preset format to confirm the legality of the signal. If the target signal contains command information, the preset format is, for example, the Mode A response format, Mode B response format, and Mode S response format in the aviation field.

[0051] Optionally, the feedback signal is a signal generated based on the target signal, which may include instruction information, feedback information and / or response information, etc., and this embodiment does not impose any limitations on it.

[0052] As another optional implementation, after receiving the low-frequency digital signal, the control module 10 decodes and verifies the low-frequency digital signal, and sends the verified signal to the external chip through the connection module 50, so that the external chip can further process the verified signal and obtain the feedback signal sent by the external chip through the connection module 50.

[0053] The specific process of sending the generated feedback signal to the target airborne equipment is as follows: After the control module 10 sends the feedback signal to the conversion module 20, the conversion module 20 performs power amplification, digital-to-analog conversion, and up-conversion processing on the received feedback signal to obtain a low-frequency analog signal. The conversion module 20 then sends the low-frequency analog signal to the frequency converter module 30.

[0054] After receiving the low-frequency analog signal, the frequency converter module 30 converts the low-frequency analog signal to obtain a second frequency-converted signal. Specifically, the frequency converter module 30 can multiply the low-frequency analog signal based on the local oscillator signal to increase the frequency of the low-frequency analog signal, thereby obtaining a second frequency-converted signal with a frequency in the target frequency band, which can be the Ka band. After obtaining the second frequency-converted signal, the frequency converter module 30 sends the second frequency-converted signal to the transceiver module 40.

[0055] After receiving the second frequency-converted signal, the transceiver module 40 performs power division and up-conversion on the second frequency-converted signal, and transmits the processed signal to the target airborne equipment through at least one antenna.

[0056] In this embodiment, the command response device includes a printed circuit board and a housing. The printed circuit board integrates a control module, a conversion module, a frequency conversion module, a transceiver module, and a connection module. One end of the connection module is fixedly connected to the signal transceiver terminal of the control module, and the other end of the connection module passes through the housing and extends outwards. Through the high integration of the modules on the printed circuit board and the design of only one connection module passing through the housing for external connection, the command response device system structure is simplified, meeting the size requirements of device miniaturization and occupying less space. Furthermore, since the command response device only includes one connection device for signal transmission to the outside world, the risk of system failure is reduced, and operational stability is improved. In the printed circuit board, the connection module, control module, frequency conversion module, and transceiver module are connected sequentially. The frequency multiplier of the frequency conversion module is adjustable, thus meeting diverse scenario requirements.

[0057] Next, refer to Figure 6 The specific structure of the frequency converter module in the above structure is described in detail. Among them, Figure 6 This is a schematic diagram of the structure of a frequency converter module 30 provided in an embodiment of this application.

[0058] Optionally, the frequency converter module 30 includes a frequency converter chip, which includes a local oscillator circuit 301 and a mixer circuit 302.

[0060] Optionally, the reference signal terminal REFin of the local oscillator circuit 301 is used to receive a reference signal, and the output terminal of the local oscillator circuit 301 is connected to the local oscillator signal terminal of the mixer circuit 302. The local oscillator circuit 301 is used to generate an internal local oscillator signal based on the reference signal and send the internal local oscillator signal to the mixer circuit 302.

[0061] Specifically, the local oscillator circuit 301 may include a local oscillator. The local oscillator is used to generate a stable oscillation signal based on a reference signal, which is used to perform mixing and other operations with the radio frequency signal received by the mixer circuit 302, converting the radio frequency signal to an intermediate frequency or other suitable frequency range for subsequent processing, such as demodulation and filtering.

[0062] Optionally, the local oscillator circuit 301 generates an internal local oscillator signal. The advantages of an internal local oscillator are high integration, good stability, and good compatibility with other circuits in the frequency converter module 30. The local oscillator circuit 301 also has an output terminal LOout to output the internal local oscillator signal to the outside.

[0063] As an optional implementation, the mixer circuit 302 can also use an external local oscillator signal for mixing via the external local oscillator interface LOin. The external local oscillator signal is provided by an oscillator external to the command response device. When the internal local oscillator signal generated by the local oscillator circuit 301 in the frequency converter module 30 cannot meet certain requirements, such as the need for higher frequency accuracy, greater power output, or more flexible frequency switching, an external local oscillator can be used. The external local oscillator can be selected and configured according to specific needs, thereby providing a more targeted oscillation signal for the mixer circuit 302.
