Description

Technical Field

[0001] This invention relates to the field of communication system technology, and more specifically, to a small motion platform integrated antenna skin communication system and method. Background Technology

[0002] Currently, as users' demands for highly integrated communication systems continue to increase, communication systems are trending towards multi-functional parallelism, high-performance processing, and dynamic reconfigurability. At the same time, as the functions that communication systems need to perform become increasingly complex, new requirements for communication system equipment, such as miniaturization, low power consumption, and high reliability, are also being put forward.

[0003] On space-constrained motion platforms, traditional communication systems suffer from the following technical problems: Insufficient noise and interference suppression in broadband radio frequency transceiver systems: Broadband noise (within the frequency band) and harmonics and spurious interference (outside the frequency band) severely damage the receiving performance, resulting in poor linearity and poor anti-interference ability, making it difficult to achieve broadband communication functions.

[0004] Low hardware resource utilization: The traditional multi-unit stacking method results in large system size, weight and power consumption, which makes it difficult to meet the adaptability requirements of motion platforms.

[0005] Poor flexibility in function switching: Function switching relies on hardware replacement or complex configuration, lacks flexible dynamic reconfiguration capabilities, and cannot adjust resource configuration in real time according to task requirements.

[0006] Lack of effective health management and fault tolerance mechanisms: When the system experiences hardware abnormalities, it cannot automatically isolate the fault and migrate functions, resulting in insufficient system reliability.

[0007] Therefore, this invention proposes a small motion platform integrated antenna skin communication system and method. Summary of the Invention

[0008] The purpose of this invention is to provide an integrated antenna skin communication system and method for small motion platforms. This system addresses the need for low- and mid-frequency radio frequency signal processing capabilities in communication devices for small motion platforms.

[0009] This communication system employs full-band segmented filtering and sampling techniques combined with digital domain spectrum stitching. It utilizes a multi-channel parallel filter and independent analog-to-digital sampling circuitry in its RF segmented transceiver array, along with a signal processing array composed of multiple heterogeneous processor chips interconnected via a TSN high-speed switching bus. Combined with an automatic reconfiguration mechanism based on health status monitoring, this system achieves the following technical objectives: decomposing broadband RF signals into multiple sub-bands for parallel sampling; recovering full-band spectrum data in the digital domain and dynamically allocating spectrum resources as needed; real-time monitoring of hardware health status and automatic isolation of faulty hardware; migrating functional threads or performing downgraded reconfiguration. This results in high-quality transmission and reception of broadband RF signals, significantly improved spectrum utilization, low-latency chip-level data interaction, and rapid reconfiguration capabilities for task switching and hardware failures, thus overcoming the aforementioned problems.

[0010] To achieve the above objectives, the technical solution adopted by the present invention is as follows: In a first aspect, this application provides a small motion platform integrated antenna skin communication system, comprising: Transceiver antennas are used for the radiation and reception of broadband radio frequency signals.

The output of the automatic gain control circuit is connected to the input of the low-noise amplifier circuit, and is used to dynamically adjust the signal gain. The output of the low-noise amplifier circuit is connected to the input of the high-speed sampling circuit for signal amplification.

[0012] Preferably, the digital domain spectrum splicing specifically includes: The independent analog-to-digital sampling data of each sub-band are digitally down-converted to zero-IF baseband signals. Each baseband signal is filtered and extracted to recover the complex envelope data of that sub-band; According to the frequency order of each sub-band in the original broadband signal, the complex envelope data is spectrally aligned and superimposed to form continuous full-band complex baseband data as full-band spectrum data.

[0013] Preferably, the multiple heterogeneous processor chips in the signal processing array are ZYNQ chips; during initialization, the communication system arbitrarily selects one ZYNQ chip from the multiple ZYNQ chips as the control and management master, and the remaining chips as slaves. The control and management master is responsible for communication system resource scheduling and management, interface management, and storage of key system instructions.

[0014] Preferably, the signal processing array also enables online loading, status monitoring, health status monitoring, comprehensive fault diagnosis, isolation, and reporting of each chip through an RS422 debug bus network.

[0015] Preferably, the automatically triggered refactoring process includes: When a task-driven working mode switch is detected, hardware resources are reallocated and the corresponding functional software is loaded according to the requirements of the new mode. When a hardware resource failure is detected, the faulty hardware is isolated, the functional threads that were originally running on the faulty hardware are migrated to healthy hardware, and the system parameters are reconfigured to restore functionality. When available hardware resources are insufficient, a downgrade refactoring is performed, loading only the core functions.

[0016] Preferably, the transceiver antenna is a conformal antenna to the motion platform, supports broadband radio frequency signal transmission and reception in the low-frequency band F1-F2>1GHz and F1<2GHz, and has an antenna selection routing matrix for selecting the transmitting antenna corresponding to the radio frequency transmission signal and the receiving channel corresponding to the radio frequency reception signal.

The signal processing array monitors the health status of hardware resources within the system. When a task-driven working mode switch or hardware resource failure is detected, a refactoring process is automatically triggered to isolate the faulty hardware and dynamically reallocate resources, thereby completing system function refactoring or degradation refactoring.

[0019] Preferably, the automatically triggered refactoring process specifically includes: When a working mode switching command is detected, hardware resources are reallocated and the corresponding functional software is loaded according to the functional requirements of the new mode. When a hardware resource failure is detected, the faulty hardware is isolated, the functional threads that were originally running on the faulty hardware are migrated to healthy hardware, and the system parameters are reconfigured to restore functionality. When available hardware resources are insufficient, a downgrade refactoring is performed, loading only the core functions.

[0020] The beneficial effects of this invention are as follows: This invention decomposes broadband signals into multiple sub-bands and uses multi-channel parallel filtering and independent analog-to-digital sampling to achieve full-band segmentation processing. The transmission and reception resources are dynamically allocated, allowing different working modes to share the same transmission and reception resources according to transmission requirements and the current status of transmission resources. This design improves the utilization of hardware resources and reduces the size, power consumption, and other overhead of hardware resource deployment while achieving multiple functions.

During operation, it synchronously starts various functional software and health monitoring modules to monitor the system status in real time. When a task-driven working mode switch or system failure is detected, it automatically triggers a reconstruction process. Through faulty hardware isolation and dynamic resource reallocation, it quickly adapts to the new operating mode or restores faulty functions, ensuring continuous and reliable system operation.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0027] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this invention, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0028] This invention proposes an integrated antenna skin communication system for small motion platforms, which can meet the miniaturization and high integration requirements of radio frequency transceiver equipment for future small motion platforms. It realizes functions such as radio frequency transceiver, signal processing, and data interaction, and provides hardware and software resources and software operating environment for the realization of integrated multi-functional radio transceiver systems.

[0029] Example 1: This embodiment provides a small motion platform integrated antenna skin communication system.

[0030] See Figure 1 The example provides an integrated antenna skin communication system architecture diagram for a small motion platform, which mainly consists of a transceiver antenna, a radio frequency segmented transceiver array, and a signal processing array.

[0031] Transceiver antennas are used for the radiation and reception of broadband radio frequency signals to complete the radiation and reception of radio frequency signals for different communication functions. The transceiver antenna is a conformal antenna to the moving platform and supports the transmission and reception of broadband radio frequency signals in the low-frequency band F1-F2 > 1GHz and F1 < 2GHz.

[0032] By designing the transceiver antenna to conform to the motion platform, the space on the platform surface is fully utilized without taking up additional internal volume of the cabin, thus meeting the requirements of miniaturization and lightweighting of communication equipment for small motion platforms.

[0033] A segmented radio frequency (RF) transceiver array, connected to the transceiver antenna, comprises two channels: a receiving channel and a transmitting channel. The RF transmitting channel primarily performs waveform generation, switching, filtering, and power amplification of the RF signal. The RF receiving channel primarily performs RF signal amplification, filtering, automatic gain control, and wideband sampling. The radio frequency segmented transceiver array is used to decompose the received broadband radio frequency signal into multiple sub-bands, and to independently sample each sub-band using multi-channel parallel filtering to obtain a full-band segmented filtered sampled signal; the full-band segmented filtered sampled full-frequency digital signal is then output to the signal processing array. By decomposing the ultra-wideband signal into multiple sub-bands for parallel processing, the sampling rate requirement for a single analog-to-digital converter is significantly reduced; multi-channel independent filtering effectively suppresses inter-band interference, thus solving the problem that phase noise, broadband noise, harmonics, and spurious interference of the transmitted signal severely degrade the receiving performance.

[0034] The signal processing array consists of a general processing unit and a recording and storage unit, and is connected to the radio frequency segmented transceiver array. The signal processing array is dynamically configured through the network to meet the needs of various functional application software for internal resources, data processing and functional algorithm implementation in real time, and simultaneously realizes system resource scheduling and management, key instruction storage and interface scheduling functions.

[0035] In some preferred embodiments, see Figure 2 The radio frequency segmented transceiver array includes functions such as routing filtering, amplification, AGC control, and wideband sampling of received signals, as well as waveform generation, amplification filtering, and routing of transmitted signals.

[0036] The radio frequency receiving channel specifically includes: The input of the full-band segmented filter bank is connected to the transceiver antenna, and the output is connected to the input of the automatic gain control circuit. This filter bank decomposes the received broadband RF signal (frequency range F1-F2 > 1GHz, F1 < 2GHz) into multiple sub-bands (e.g., one sub-band every 100MHz), and performs bandpass filtering on each sub-band to suppress interference between adjacent sub-bands. Through segmented filtering, the RF segmented transceiver array effectively suppresses mutual interference between sub-bands, providing a clean signal input for subsequent parallel sampling and resolving broadband noise interference within the frequency band.

[0037] The output of the automatic gain control circuit is connected to the input of the low-noise amplifier circuit. It dynamically adjusts the gain according to the strength of the input signal to prevent saturation of subsequent circuits or deterioration of the signal-to-noise ratio. It avoids the problems of ADC saturation caused by strong signals and insufficient signal-to-noise ratio caused by weak signals, and ensures the dynamic range and linearity of signal sampling across the entire frequency band.

[0038] The output of the low-noise amplifier circuit is connected to the input of the high-speed sampling circuit to amplify weak signals with low noise and improve receiving sensitivity.

[0039] The high-speed sampling circuit employs multiple independent high-speed analog-to-digital (ADC) sampling circuits, each corresponding to a sub-frequency band. Each circuit performs independent ADC sampling to obtain a full-band digital signal after segmented filtering and sampling, which is then output to the signal processing array. This multi-channel parallel sampling architecture significantly improves data throughput, enabling real-time sampling across the entire frequency band and supporting real-time processing of large-bandwidth signals.

[0040] The transmission channel specifically includes: The waveform generation circuit receives transmitted data (baseband I / Q data) from the signal processing array and generates intermediate frequency or radio frequency signals through digital-to-analog conversion and quadrature modulation.

[0041] The power amplifier circuit amplifies the generated radio frequency signal to meet the transmission power requirements.

[0042] The filtering circuit filters the power amplifier output to suppress out-of-band spurious signals and harmonics, and then sends the signal to the transceiver antenna for radiation.

[0043] This invention employs full-band segmented filtering and sampling with digital domain spectrum stitching technology to achieve unified processing and dynamic allocation of full-band spectrum data. This allows various communication functions to call upon the required frequency bands as needed, enabling full-band data to be accessed online and effectively improving spectrum utilization efficiency. Its core capabilities rely on the RFSOC hardware platform of RFADC / DAC+FPGA. Through real-time processing of high-frequency radio frequency signals, it achieves multi-protocol physical layer adaptation (including modulation / demodulation and filtering operations). Combined with software dynamic reconfiguration capabilities, it adjusts bandwidth and modulation parameters in real time to support protocol expansion. Furthermore, based on despreading and decoding after analog-to-digital conversion and signal synthesis before digital-to-analog conversion, it ensures low-latency, high-speed communication performance, ultimately achieving flexible and reconfigurable processing of radio frequency signals.

[0044] Figure 3 The diagram shown is a schematic of the signal processing array architecture provided in the embodiment. The signal processing array includes a general-purpose processing unit and a recording and storage unit, providing hardware and software resources and a software operating environment for the integrated antenna skin communication system of a small motion platform.

[0045] Multiple ZYNQ chips (e.g., 4 or 8) are deployed within the general-purpose processing unit, forming a general-purpose processing resource pool for radio frequency signals. All chips are interconnected at the chip level with low latency (end-to-end latency less than 10μs) through a TSN (Time-Sensitive Network) exchange network.

[0046] During system initialization, any ZYNQ chip is selected as the control and management host. Under the system's control and management, dynamic network configuration meets the functional requirements of various application software for internal resources, data processing, and functional algorithm implementation. Its main functions include system resource scheduling and management, as well as the storage of key system instructions and data. As the digital hardware core of the integrated antenna skin communication system for small motion platforms, a 30% margin has been considered in the component selection to accommodate future functional expansion needs.

[0047] After receiving multi-channel sub-band sampling data from the high-speed sampling circuit, the signal processing array performs the following steps: S301. Multiply the bandpass sampling data of each sub-band by the digital local oscillator (NCO) to convert it into a zero-IF baseband signal. The digital local oscillator frequency of each sub-band is set according to the center frequency of that sub-band.

[0048] S302. Perform low-pass filtering and decimation on each baseband signal to filter out high-frequency image components, reduce the data rate, and recover the complex envelope data (I / Q channels) of that sub-band.

[0049] S303. According to the frequency order of each sub-band in the original broadband signal (from low frequency to high frequency), the complex envelope data of each sub-band is spectrum shifted in the digital domain (adjusted to the correct frequency position) and superimposed to form continuous full-band complex baseband data, i.e. full-band spectrum data.

[0050] To obtain more accurate spectral characteristics, the signal processing array can perform multiple calculations on spectral data over consecutive time periods and take the average or maximum value of the multiple spectral calculations as the final spectral result, thereby improving noise immunity and detection reliability.

[0051] After obtaining the full-band spectrum data, the signal processing array dynamically allocates spectrum resources according to the frequency band requirements of each communication function (such as telemetry and control communication, high-speed data transmission, inter-satellite communication, etc.). For example, when the high-speed data transmission function needs to be activated, the system automatically allocates a free frequency band with good channel quality from the full-band spectrum for the function to use; when a function ends, the frequency band resources it occupies are released for other functions to call.

[0052] The multi-protocol unified processing-based multi-communication function is implemented through protocol processing, message parsing, processing, and interaction with the task machine.

[0053] The communication system is connected via fiber optic cable through an integrated task processor. It uses online upgrade agent protocol software to realize remote software file transfer, local updates of the upgraded unit, and return of loading results, ensuring efficient online upgrades. At the same time, its control and management functions dynamically generate system function configuration schemes based on communication mode and resource health status, allocate resources in real time, and complete the assembly of function threads.

[0054] The health status monitoring and fault diagnosis specifically includes: a signal processing array connected to each chip and functional module via an RS422 debug bus network, periodically collecting health data such as temperature, voltage, current, and operating status of each chip. When a chip's temperature exceeds a threshold, its voltage is abnormal, or its logic function malfunctions, it is determined that the hardware resource has failed. The system also has comprehensive fault diagnosis capabilities, able to distinguish between transient and permanent faults.

[0055] The automatic reconfiguration process specifically includes: S3001, when the task machine issues a mode switching instruction (e.g., switching from measurement and control mode to high-speed data transmission mode), the control management host reallocates hardware resources (e.g., allocating more FPGA logic resources or DSP cores for high-speed modulation and demodulation) according to the functional requirements of the new mode, and loads the corresponding functional software from the storage area to complete the dynamic assembly of functional threads.

[0056] S3002. When a hardware resource failure is detected, the control and management host first isolates the faulty hardware and cuts off its power supply or resets it. Then, it migrates the functional threads that were originally running on the faulty hardware to healthy hardware resources and reconfigures the system parameters to restore functionality. If the currently available hardware resources are insufficient to ensure the normal operation of all functions, a degradation and reconstruction is performed: only core functions are loaded, non-critical functions are disabled, and the fault and degradation status are reported to the task machine.

[0057] The S3003 module stores the basic startup program and core functional software in the hardened area, while the reconfigurable area stores online-update functional software. The communication system manages the FPGA, which defaults to hardened area startup upon power-up. Upon receiving a reconfigurable area startup command, it loads the reconfigurable area configuration file, enabling on-orbit / online software reconfiguration.

[0058] The communication system supports rapid switching of runtime functions through automatic refactoring process settings, without requiring a system restart; resource allocation on demand ensures that the current function receives optimal processing power, improving user experience and task completion efficiency; at the same time, single point of failure does not affect the overall communication function; fault isolation prevents fault propagation; and degradation refactoring ensures that the communication system can maintain basic communication even when resources are scarce, guaranteeing platform security.

[0059] Example 2: The following uses a communication system for a small unmanned aerial vehicle (UAV) as an example to illustrate the typical workflow of this invention: Power-on initialization: After the communication system powers on, each ZYNQ chip in the signal processing array starts up and performs discovery and election via the TSN bus, with one chip becoming the control and management master. The master reads the configuration from the firmware area, allocates initial resources, and loads default function software (such as remote control and telemetry functions). The RF segment transceiver array completes self-test and initialization.

[0060] Normal operation: The transceiver antenna receives ground remote control signals. After segmented filtering, amplification, AGC, and high-speed sampling by the RF segmented transceiver array, the sampled data is sent to the signal processing array. The signal processing array performs spectrum stitching, extracts remote control command data, parses it, and executes corresponding operations, such as adjusting flight parameters. Simultaneously, the communication system monitors the health status of each chip in real time.

[0061] Mode Switching: The ground station issues a command to activate the high-definition video data transmission mode. Upon receiving the command, the signal processing array automatically reconstructs the signal: loading the modulation and coding software module for video data transmission from storage, allocating some FPGA resources and DSP cores for video compression and high-speed modulation, and adjusting the parameters of the RF transmission channel (such as bandwidth and transmission power). Video data is then transmitted in real time through the high-speed data transmission channel.

[0062] Fault Handling: Suppose a ZYNQ chip malfunctions due to overheating. The health management module detects that the chip's temperature has exceeded the limit. The control management host immediately migrates the functional threads running on this chip to other healthy chips (e.g., migrating filtering tasks originally handled by the faulty chip to a backup chip), then isolates the faulty chip (by resetting or powering it off) and reports the fault information to the ground station. The entire migration process is completed in milliseconds without interrupted communication.

[0063] Degraded operation: If multiple chips fail simultaneously, resulting in a severe shortage of available resources, the communication system will automatically enter a degraded mode: maintaining only basic remote control and telemetry communication functions, disabling non-core functions such as video data transmission, and ensuring the safe return of the aircraft.

[0064] Example 3: See Figure 4 This application also provides a small motion platform integrated antenna skin communication method for any of the above-mentioned communication systems, comprising: S1. Receive broadband radio frequency signals through a transceiver antenna; S2. The broadband radio frequency signal is decomposed into multiple sub-bands by a radio frequency segmented transceiver array, and each sub-band is subjected to multi-channel parallel filtering and independent analog-to-digital sampling to obtain a full-band digital signal after full-band segmented filtering and sampling. S3. The full-frequency digital signal is digitally spliced ​​using a signal processing array to form unified spectrum data across the entire frequency band, and spectrum resources are dynamically allocated to each currently running communication function as needed. The signal processing array monitors the health status of hardware resources within the system. When a task-driven working mode switch or hardware resource failure is detected, a refactoring process is automatically triggered to isolate the faulty hardware and dynamically reallocate resources, thereby completing system function refactoring or degradation refactoring.

[0065] Preferably, the automatically triggered refactoring process specifically includes: S3001. When a working mode switching command is detected, hardware resources are reallocated and corresponding functional software is loaded according to the functional requirements of the new mode. S3002. When a hardware resource failure is detected, the faulty hardware is isolated, the functional threads originally running on the faulty hardware are migrated to healthy hardware, and the system parameters are reconfigured to restore functionality. S3003: When available hardware resources are insufficient, perform a downgrade refactoring and load only the core functions.

The integrated antenna skin communication system for a small motion platform according to claim 1, characterized in that, The transceiver antenna is a conformal antenna to the motion platform, supporting broadband radio frequency signal transmission and reception in the low-frequency band F1-F2>1GHz and F1<2GHz, and has an antenna selection routing matrix for selecting the transmitting antenna corresponding to the radio frequency transmission signal and the receiving channel corresponding to the radio frequency reception signal.

8. A small motion platform integrated antenna skin communication system according to any one of claims 1 to 7, characterized in that, include: The frequency range of the broadband radio frequency signal is F1-F2 > 1GHz, and F1 < 2GHz.

9. A method for communication using an integrated antenna skin on a small motion platform, used in the communication system described in any one of claims 1 to 8, characterized in that, include: Receive broadband radio frequency signals through a transceiver antenna; The broadband radio frequency signal is decomposed into multiple sub-bands by a radio frequency segmented transceiver array, and each sub-band is subjected to multi-channel parallel filtering and analog-to-digital sampling to obtain a full-band digital signal after full-band segmented filtering and sampling. The full-band digital signals are digitally spliced ​​using a signal processing array to form unified full-band spectrum data, and spectrum resources are dynamically allocated to the currently running communication functions as needed. The signal processing array monitors the health status of hardware resources within the system. When a task-driven working mode switch or hardware resource failure is detected, a reconfiguration process is automatically triggered to isolate the faulty hardware and dynamically reallocate resources, thereby completing system function reconfiguration or degradation reconfiguration. When processing the signal output by the RF segment transceiver array, the signal processing array is configured to perform analog-to-digital conversion and digital down-conversion on the signal output by the RF segment transceiver array, and to perform multiple spectrum calculations on the down-converted digital signal, taking the average or maximum value of the multiple spectrum calculations as the spectrum result.

10. A method for integrated antenna skin communication for a small motion platform according to claim 9, characterized in that, The automatic triggering reconstruction process specifically includes: When a working mode switching command is detected, hardware resources are reallocated and the corresponding functional software is loaded according to the functional requirements of the new mode. When a hardware resource failure is detected, the faulty hardware is isolated, the functional threads that were originally running on the faulty hardware are migrated to healthy hardware, and the system parameters are reconfigured to restore functionality. When available hardware resources are insufficient, a downgrade refactoring is performed, loading only the core functions.
