Description

Technical Field

[0001] This invention relates to the field of avionics equipment testing and maintenance technology, specifically to an airborne communication identification and navigation system tester and its testing method. Background Technology

[0002] Modern civil aircraft are generally equipped with highly integrated communication, navigation, and identification (CNI) systems. These systems typically integrate multiple functional modules, including shortwave communication, VHF voice and data link communication, TACAN, instrument landing system, microwave landing system, automatic dependent surveillance broadcast (ADS-B), and aircraft identification system (AIS). These subsystems work together to ensure flight safety, airspace management efficiency, and mission execution capabilities, and their operational status directly affects the success or failure of flight missions and personnel safety.

[0003] In current airborne CNI system maintenance practices, testing methods still primarily rely on fixed integrated test benches or dedicated test equipment for single functions. These devices are generally bulky and heavy, making them unsuitable for real-world scenarios with limited hangar space and rudimentary field support conditions, thus limiting rapid response and mobile support capabilities. Furthermore, because various devices operate independently, maintenance personnel must frequently change instruments, connect different types of antennas or cables, and use vastly different software interfaces, resulting in a lengthy and cumbersome testing process and low fault location efficiency.

[0004] Most existing testing equipment can only perform isolated tests on a single subsystem, lacking the ability to simulate the interconnected signals and collaborative working mechanisms of multiple systems. During actual flight, there are complex interface interactions and information coupling between the various CNI subsystems, and traditional testing methods are unable to reproduce such working scenarios, resulting in some system-level or interface-level faults not being effectively identified, thus creating potential safety hazards.

[0005] Current mainstream testing equipment also suffers from significant shortcomings in terms of informatization and intelligence. Data during the testing process often relies on manual recording, lacking a unified data storage, analysis, and traceability mechanism; the interpretation of test results is highly subjective, making it difficult to support subsequent condition assessment and predictive maintenance. Furthermore, the equipment generally lacks functions such as remote data transmission and automatic generation of standardized test reports, hindering the development of maintenance support systems towards digitalization, networking, and intelligence.

[0006] Therefore, in the face of increasingly complex airborne CNI system architecture and high-intensity support requirements, there is an urgent need for a new type of testing device that can take into account multi-system integrated testing capabilities, portability, ease of operation, and information level, so as to break through the bottlenecks of existing technologies in terms of flexibility, collaboration, and intelligence, and comprehensively improve the efficiency and reliability of aviation equipment maintenance and support. Summary of the Invention

[0007] The purpose of this invention is to address the problems of existing airborne communication identification and navigation system testing equipment being scattered, bulky, complex to operate, functionally limited, and lacking in information technology, making it difficult to meet the needs of rapid, comprehensive, and intelligent field maintenance. Therefore, this invention proposes an airborne communication identification and navigation system testing instrument and its testing method. This invention employs a hardware architecture combining a general-purpose processing platform with a micro-communication function daughter card and SDR synthesis instrument technology, which can significantly reduce the size and weight of the equipment and efficiently achieve multi-functional comprehensive testing of multiple airborne communication identification and navigation devices on a single platform.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0025] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0026] An airborne communication identification and navigation system detector, the composition of which can be found in [reference needed]. Figure 1 The diagram mainly includes a core processing and control unit, a multi-band radio frequency conditioning unit, and an integrated interface unit.

[0027] The core processing and control unit is built on a general-purpose processing platform, programmable logic devices, and software-defined radio transceiver modules, and is used to execute overall control, signal processing algorithms, and protocol parsing. This unit enhances the software programmability and reusability of the hardware modules, and can implement the detection of various functions in a software-defined manner; the overall digital circuitry involved is a comprehensive architecture in the form of "AMR + ZYNQ + frequency-agile daughter card", which can minimize power consumption and meet the requirements of miniaturized handheld devices.

[0028] The multi-band RF conditioning unit is connected to the core processing and control unit and includes configurable digital-to-analog conversion channels, analog-to-digital conversion channels, and multiple RF conditioning channels for transmitting and receiving RF signals in different frequency bands. Through components such as controllable attenuators, amplifiers, and filter arrays within this unit, signal level conditioning, gain compensation, and spurious suppression for multiple frequency bands can be achieved.

[0029] The integrated interface unit connects to the core processing and control unit and the multi-band RF conditioning unit, including a multi-band antenna interface for connecting antennas of different bands and a human-machine interface for providing operation and display functions. This unit provides high-density quick-connect connectors required for both internal and external use of the instrument, with multiple connectors integrated into the main body structure, thus providing various physical interfaces required for field use of the instrument. These interfaces may include RF coaxial interfaces, headphone / microphone interfaces, metrology / calibration interfaces, maintenance / adjustment interfaces, security device interfaces, power interfaces, sensor interfaces, input / output interfaces, control interfaces, and network interfaces.

[0030] In this embodiment, the core processing and control unit adopts a fully domestically produced component design. Its general-purpose processing platform includes an ARM core processing board and a power management unit. The ARM core processing board is equipped with a T3 pro processor; and preferably, in this embodiment, the ARM core processing board runs an embedded operating system, specifically the domestically produced Winghui embedded operating system. The power management unit can be powered by connecting to an external AC power supply via a power adapter, or directly powered by a portable rechargeable battery built into the detector. The programmable logic device is a Field Programmable Gate Array (FPGA), specifically the FMQL45T900.

[0031] In this embodiment, the software-defined radio transceiver module includes a frequency-agile transceiver, a high-speed analog-to-digital converter (ADC), and a high-speed digital-to-analog converter (DAC). Preferably, the frequency-agile transceiver is model B9361NYB, the high-speed ADC is model B2209E, and the high-speed DAC is model JDDS9957. The frequency-agile transceiver is used to perform frequency conversion processing of the radio frequency signal; the high-speed ADC is used to convert the received analog radio frequency signal into a digital signal; and the high-speed DAC is used to convert the processed digital signal back into an analog radio frequency signal.

[0032] In this embodiment, the core processing and control unit also includes a multi-channel low-speed ADC, model XYAD7606-8, which can be used to acquire multiple analog signals. By combining the above-mentioned domestically produced components with a domestically produced embedded operating system, the main control processes and signal processing of the detector can be efficiently implemented.

[0033] For a multi-band RF conditioning unit, its multiple RF conditioning channels include at least two high-speed inverter RF conditioning channels; the digital-to-analog conversion channel includes a high-speed DAC signal conditioning channel; the analog-to-digital conversion channel includes a high-speed ADC signal conditioning channel; and the RF signal conditioning path is composed of at least two high-speed inverter RF conditioning channels, a high-speed DAC signal conditioning channel, and a high-speed ADC signal conditioning channel.

[0034] The multi-band RF conditioning unit thus establishes RF electrical connections with the high-speed analog-to-digital converter (ADC), the high-speed digital-to-analog converter (DAC), and at least two agile transceivers in the core processing and control unit.

[0035] As a preferred embodiment of this invention, the multi-band antenna interface of the integrated interface unit includes a high-frequency (HF) / ultra-high-frequency (UHF) UV band antenna port, an L-band antenna port, and a C-band antenna port, which are used to connect antennas of the corresponding bands.

[0036] As a preferred embodiment, the human-computer interaction interface of the integrated interface unit includes an AMOLED touch screen and multiple types of function buttons. The touch screen is preferably 8.01 inches in size and utilizes existing mature technology to provide adjustable brightness and sunlight visibility.

[0037] As a preferred embodiment, the integrated interface unit further includes a device housing, which can be seen in [reference needed]. Figures 2 to 6 The diagram illustrates the enclosure structure that forms the detector, housing the core processing and control unit and the multi-band radio frequency conditioning unit. In this embodiment, the housing also provides space on its outer surface for the multi-band antenna interface and human-machine interface, as well as various hardware structures that can be mounted on the detector surface. The preferred configuration of this embodiment is described below: like Figure 2 As shown, the front of the detector includes a faceplate 1, a faceplate lens 2, a photosensor 3, a power button 4, and navigation and function buttons 5. The faceplate lens 2 protects the touchscreen display, utilizing existing mature display technology; the photosensor 3 enables the touchscreen display to automatically adjust its brightness according to the intensity of external light.

[0038] like Figure 3 As shown, on the right side of the detector, there is a decorative strap 13, a strap buckle 14, and a test interface 15. The decorative strap 13 and strap buckle 14 can be configured at any corner of the detector as needed, making it convenient for operators to carry; the test interface 15 is used to connect to a host computer or other equipment, so that it can establish a test connection with the core processing and control unit inside the detector.

[0039] like Figure 4 As shown, on the top surface of the detector, there are Xs1 connector 6, first RF connector 7, second RF connector 8, third RF connector 9, 32-pin low-frequency socket 1V 10, 8-pin RF socket 1V 11, and 5-pin RF socket 1V 12. Among them, the first RF connector 7, the second RF connector 8, and the third RF connector 9 are multi-band antenna interfaces, and are in the form of RF coaxial interfaces, which can respectively correspond to the high-frequency HF / ultra-high-frequency UV band antenna port, L-band antenna port, and C-band antenna port to connect antennas of the corresponding bands.

[0040] like Figure 5 As shown, an SEC interface 18 and a nameplate 19 are located on the bottom of the detector. The SEC interface 18 is a secure encrypted communication interface that enables the input and output of encrypted signals, ensuring the confidentiality of communication data during transmission.

[0041] like Figure 6As shown, a back cover 16 and a battery interface 17 are provided on the back of the detector. The back cover 16 and the front cover 1 are closed to form the enclosure structure of the detector; the battery interface 17 provides installation space for a portable rechargeable battery.

[0042] As a preferred embodiment, the device housing is milled from rust-resistant aluminum (5A06) and the surface is coated with fluoropolyurethane enamel after colored conductive oxidation treatment. Anti-slip textures or rubber grips can be designed on both sides of the device housing to improve grip stability during use.

[0043] In this embodiment, such as Figure 7 As shown, the tester's software architecture adopts a modular design, including an FPGA software module running on a programmable logic device and an embedded software module running on an ARM core processing board in a general-purpose processing platform. The FPGA software module is used to implement the core signal processing algorithm and control the multi-band RF conditioning unit; the embedded software module is used to implement the device control logic, communication protocol parsing, test database management, and test report generation functions.

[0044] When the host computer is connected to the testing instrument, it can establish communication with the ARM core processing board through the test interface. Therefore, if it is necessary to modify the corresponding program for a certain test function, only the software module of that program needs to be adjusted. If other test functions are to be added, only a corresponding software module or software interface needs to be added. This makes the testing instrument of this embodiment have good openness and expandability, and software upgrades are relatively simple.

[0045] The FPGA software module implements the software functions of the software-defined radio transceiver module. It can specifically perform the core algorithms for each test function, control the multi-band RF conditioning unit, and transmit data with the ARM core processing board via an external bus. The ARM core processing board's processor runs the WingHui operating system and interacts with the host computer or other devices through interfaces such as Ethernet and serial ports. By dynamically loading functional waveforms and rationally allocating functional threads, the ARM processor's utilization rate can be kept at a low level.

[0046] Ultimately, the detector of this embodiment, while ensuring radio frequency performance and processing capabilities, achieves dynamic management of the power management unit based on existing mature technologies through the aforementioned chip selection and hardware composition design. This enables the detector to achieve a high degree of integration of structure and interface under low power consumption, allowing it to be used handheld by users and enabling efficient detection of airborne communication identification and navigation systems.

[0047] This embodiment also provides a detection method based on the airborne communication identification and navigation system detector, i.e., a preferred detection method using the detector, which may include the following steps performed sequentially: S1. Receive the user's selected type of airborne equipment to be tested and test item instructions through the human-machine interface of the integrated interface unit; S2, the core processing and control unit configures the parameters of the multi-band radio frequency conditioning unit according to user instructions, including setting the band of the multi-band antenna interface, configuring the working mode of the digital-to-analog conversion channel and the analog-to-digital conversion channel, and setting the frequency and gain of multiple radio frequency conditioning channels; S3, the core processing and control unit controls the multi-band radio frequency conditioning unit, and sends radio frequency test signals to the airborne equipment under test through the multi-band antenna interface; S4, the core processing and control unit controls the multi-band radio frequency conditioning unit, which receives radio frequency response signals from the airborne equipment under test through the multi-band antenna interface; S5, the core processing and control unit, acquires, performs analog-to-digital conversion and digital signal processing on the received radio frequency response signal, and executes signal processing algorithms to analyze signal characteristics; S6, the core processing and control unit executes protocol parsing, compares the analyzed signal characteristics with preset protocol standards or thresholds, and determines the functional or performance status of the airborne equipment under test. S7, the core processing and control unit, generates test data based on the judgment results and stores it in the built-in database; S8, the core processing and control unit, calls the report generation module to automatically generate an electronic test report containing test results and status judgments based on the stored test data and preset report templates.

[0048] As a preferred embodiment of this implementation, step S8 automatically generates an electronic test report, including: filling the test results, status judgment, test time, and identification information of the tested airborne equipment into the report template according to a preset standardized format; storing the generated electronic test report to a specified local or remote storage path; and displaying the electronic test report or providing an export option through a human-computer interaction interface.
