[0009] To enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Based on the embodiments in this application, other similar embodiments obtained by those skilled in the art without creative effort should all fall within the scope of protection of this application.

[0010] The meanings of the communication terms involved are explained below: VHF: Very High Frequency Communication System.

[0011] ACARS: Aircraft Communications Addressing and Reporting System.

[0012] ILS: Instrument Landing System.

[0013] GLS: Satellite Landing System.

[0014] VOR: Very High Frequency Omnidirectional Beacon.

[0015] The embodiments of the present invention mainly design a complete communication radio frequency link and signal processing reconfigurable architecture based on the communication frequency band and functional performance requirements of different communication functions, so as to enable multiple functions to be time-division multiplexed under a small amount of hardware.

[0016] Example 1 like Figure 1As shown, this invention provides a multi-functional reconfiguration and reuse (UV) general platform for aviation radio communication. The general platform includes three radio communication branches and a multiplexing and reconfiguration module for combining and designing the communication functions enabled by the radio communication branches according to the needs of the usage scenario.

[0017] Each of the three radio communication branches includes a radio frequency link module and a communication signal processing module.

[0018] Each radio frequency link module implements multiple radio communication functions. It integrates the sensitivity, dynamic range, signal bandwidth, adjacent channel selectivity, image rejection, and spurious harmonic rejection requirements of multiple radio communication functions and adjusts them according to the specific communication function being enabled.

[0019] In a preferred embodiment, the RF link module adopts a double superheterodyne architecture frequency conversion method, and designs a superheterodyne frequency conversion link to ensure all functional performance indicators. The supported operating frequency range covers the V band 108.000MHz~136.975MHz and the U band 329.150MHz~335.000MHz.

[0020] In a preferred embodiment, the radio frequency (RF) link module includes an RF control board, an RF submodule, a frequency conversion chain submodule, and a low-IF submodule. The RF submodule includes amplification and filtering units, the frequency conversion chain submodule includes high-LO and low-LO units, and the low-IF submodule includes filtering, amplification, and automatic gain control (AGC) units. The RF control board adjusts the signal operating frequency bands of the RF submodule, frequency conversion chain module, and low-IF submodule to the frequency band corresponding to the radio communication function to be enabled.

[0021] In a preferred embodiment, each RF link module can implement five communication functions: VHF communication system, Aircraft Communication Addressing and Reporting System (ACARS), Instrument Landing System (ILS), Satellite Landing System (GLS), and VHF Omnidirectional Beacon (VOR). Since the hardware design of the general platform must simultaneously meet the functional and performance requirements of VHF communication system, ACARS, ILS, GLS, and VOR, the corresponding RF link module supports adjusting the RF signal from -103.5dBm to +25dBm to the intermediate frequency AD sampling amplitude of -40dBm to +5dBm via AGC; the AGC response time is less than 10µs in fast mode and less than 50ms in slow mode under different functions; and the low-IF signal bandwidth is 25kHz.

[0022] The communication signal processing module includes a first chip module and a second chip module, wherein the first chip module is used for signal control and management when multiplexing and reconstructing communication functions in different scenarios; and the second chip module is used for signal modulation and demodulation processing.

[0023] In a preferred embodiment, the first chip module uses a ZYNQ chip, and the second chip module uses a DSP6678 chip for signal processing. The ZYNQ chip's local reconstruction function is used for control and management when reconstructing various functions required in different scenarios, such as control management, protocol processing, signal sampling, and software reconstruction. The DSP6678 is mainly used for modulation and demodulation processing of signals, and its signal processing capabilities need to meet the real-time processing requirements of VHF communication systems, Aircraft Communication Addressing and Reporting Systems (ACARS), Instrument Landing Systems (ILS), Satellite Landing Systems (GLS), and VHF Omnidirectional Beacons (VOR).

[0024] Furthermore, the communication signal processing module also includes communication middleware for a unified interface.

[0025] The reuse and reconfiguration module comprehensively analyzes the communication frequency bands and functional usage scenarios of five functions: VHF communication system, Airborne Addressing and Reporting System (ACARS), Instrument Landing System (ILS), Satellite Landing System (GLS), and VHF Omnidirectional Beacon (VOR). It combines the communication functions enabled by the three radio communication branches according to the usage scenario, thereby realizing the reuse and reconfiguration of communication functions in different stages or scenarios.

[0026] In a preferred embodiment, the general platform application scenarios provided by the present invention are mainly divided into three stages: takeoff, level flight, and landing. According to the stage analysis, VHF, ACARS, ILS, GLS, and VOR functions are implemented through multiplexing and reconfiguration on three sets of radio frequency link modules.

[0027] Specifically, during takeoff and level flight, VHF and VOR are used, ACARS is selected but ILS and GLS are not used; during landing, VHF is used, either ILS or GLS is selected, ACARS is selected, and VOR is not used.

[0028] Therefore, the three RF links in the general platform design can meet the multiplexing of five functional requirements in different scenarios, and can ensure the normal operation of the necessary functions by avoiding faulty modules, thereby improving reliability.

[0029] Example 2 This embodiment describes a design method for a multi-functional reconfiguration and multiplexing UV universal platform for aviation radio communication, as described in any of the foregoing embodiments. Figure 2 As shown, the method includes: Configure at least two radio communication branches and one multiplexing and reconfiguration module; The reuse and reconfiguration module selects the radio communication functions enabled for each radio communication branch based on the usage scenario, thus obtaining a combination of radio communication branches.

[0030] Furthermore, the communication middleware provides a unified interface, shielding specific hardware information, and each communication waveform independently develops its own communication algorithm.

[0031] Specifically, when the avionics display and control system issues functional commands such as VHF / ACARS / ILS / GLS / VOR according to the current usage requirements, the communication middleware completes the reconstruction, loading and operation of the Zynq software functions and DPS software functions related to the communication waveform.

[0032] Example 3 This embodiment provides a non-transitory computer-readable storage medium storing computer instructions for causing a computer to implement a design method for a multi-functional reconfigurable multiplexed UV general platform for aviation radio communication described in any of the foregoing embodiments.

[0033] Example 4 This embodiment provides a computer program product, which includes a computer program that, when executed by a processor, is used for a design method of a multi-functional reconfigurable multiplexed UV general platform for aviation radio communication described in any of the foregoing embodiments.

[0034] In summary, this invention provides a multi-functional reconfigurable and reusable UV universal platform solution for aviation radio communication, which centralizes the functions of aviation radio on the same platform, avoiding the problem of dedicated hardware, improving equipment integration, realizing the trend of integrated miniaturization, maximizing resource sharing, and improving the reconfigurability and upgradeability of avionics systems.

However, it should be noted that the examples described above are merely preferred embodiments of the present invention and are not intended to limit the present invention. The present invention can have various modifications and variations. For example, the second superheterodyne receiver architecture can be changed to another receiver architecture according to the requirements of the aircraft's self-sound function. The number of RF communication links can be greater than 3, and the number of radio communication functions can be greater than 5, depending on the specific scenario requirements. The communication signal processing platform is not limited to the Zynq7045 and DSP6678 used in this example. It can be changed according to the requirements of algorithm resources, real-time performance, etc. However, the core must support functional reconfiguration to meet the improved requirement of the present invention to achieve multiple radio communication functions through multiple RF communication links.
