Description

Technical Field

[0001] This invention belongs to the field of T / R component testing technology, specifically referring to a comprehensive intelligent testing and fault location system for airborne radar T / R components. Background Technology

[0002] As the core unit of active phased array radar, the performance of the airborne radar T / R module directly determines the overall effectiveness of the radar system. Airborne radars typically integrate hundreds or thousands of T / R modules, making efficient and accurate performance testing and fault location crucial during the research, development, production, and maintenance phases.

[0003] Existing testing methods for transceiver (T / R) components mainly include manual discrete instrument testing, semi-automatic test systems, and dedicated test equipment. Manual discrete instrument testing is inefficient, prone to human error, and struggles to quickly locate internal faulty modules or components. While semi-automatic test systems have improved, their integration and test coverage are limited, typically covering only some RF performance indicators. Their control logic is relatively simple, lacking intelligent fault diagnosis capabilities. Dedicated test equipment suffers from poor versatility and high development costs. Existing technologies generally suffer from low automation, low testing efficiency, and insufficient fault location capabilities. Particularly in fault location, existing technologies can only identify performance parameter anomalies but cannot intelligently and progressively analyze and locate the specific root cause of the fault, such as power amplifier failure or control logic errors.

[0004] Therefore, there is a lack of existing technologies that can achieve intelligent detection and fault location to meet the high-quality, high-efficiency, and high-reliability testing and support requirements of modern airborne radar T / R components. Summary of the Invention

[0005] This invention overcomes the shortcomings of existing technologies and provides a comprehensive intelligent detection and fault location system for airborne radar T / R components. Through a main control module, an RF testing module, a multi-channel RF switching matrix, and a programmable power management module, it can quickly and accurately measure all key performance indicators of the T / R components. Through data interaction between the intelligent diagnosis and fault location module and the comprehensive database module, it can intelligently compare and perform hierarchical reasoning on the test data, ultimately achieving accurate fault location from the component level to the part level, effectively solving the problems existing in the prior art.

[0006] The technical solution adopted by this invention is as follows: This solution provides an integrated intelligent detection and fault location system for airborne radar T / R components, including a main control module, an RF test module, a multi-channel RF switching matrix, a precision test fixture, a programmable power management module, an intelligent diagnosis and fault location module, and an integrated database module.

[0007] The main control module serves as the control and data processing center of the entire system. It is responsible for coordinating the start, execution, pause, and termination of the entire test process; sending control commands and configuration parameters to other functional modules; and receiving, processing, and storing test data and status information from each module in real time.

[0008] The RF test module generates and measures RF signals, and integrates a vector network analysis unit and a spectrum and power analysis unit. The vector network analysis unit measures the S-parameters of the T / R component (such as transmit / receive gain, insertion loss, input / output VSWR, phase shift accuracy / attenuation accuracy); the spectrum and power analysis unit measures the dynamic performance indicators of the T / R component in transmit mode, such as transmit power, 1dB compression point, harmonic rejection ratio, spurious emissions, and noise figure in receive mode.

[0009] The core function of a multi-channel RF switching matrix is ​​to automatically, quickly, and accurately construct RF test paths under the control of the main control module. The multi-channel RF switching matrix has multiple input ports and multiple output ports. The input ports connect to the test ports of the RF test module, and the output ports connect to the RF interface of the precision test fixture. Through internal switch array combinations, the multi-channel RF switching matrix enables flexible connection between the RF test module and any RF channel of the T / R component under test.

[0010] Precision test fixtures serve as the physical interface between the T / R component under test and the test system. They support, fix, and provide the T / R component under test with a low-loss, high-isolation RF signal transmission channel and a stable DC power supply and control signal interface.

[0011] The programmable power management module provides multiple, high-precision, programmable DC operating voltages for the T / R module under test, and monitors the voltage and current consumption of each power supply in real time. The programmable power management module can simulate the actual power supply conditions of the T / R module in a radar system and has overvoltage, overcurrent, and overtemperature protection functions.

[0012] The intelligent diagnosis and fault location module, running as software on the main control module, is the core embodiment of the intelligent features of this invention. This module has a built-in fault knowledge base for the T / R components. By comparing and analyzing real-time test data with standard data in the comprehensive database module, it employs a hierarchical diagnosis strategy to automatically determine the operating status of the T / R components. When a fault occurs, it narrows down the fault range layer by layer, ultimately pinpointing the specific faulty functional module (such as the transmit channel module, receive channel module, programmable power management module, control logic module) or even a suspected component.

[0013] The integrated database module stores and manages all test-related data, including the model and specifications of the tested T / R component, nominal performance parameters (i.e., the "gold standard"), historical test data, fault cases, diagnostic rules, and test reports. The integrated database module provides data support for the intelligent diagnostic and fault location module and supports the traceability, statistics, and analysis of test data.

[0014] Furthermore, the main control module communicates at high speed with the RF test module and the programmable power management module via a system bus (such as PCIe or LAN); the main control module sends path switching commands to the multi-channel RF switching matrix via a control bus (such as USB or GPIB); the RF test module is connected to the input of the multi-channel RF switching matrix via an RF cable; the output of the multi-channel RF switching matrix is ​​connected to the RF port of the precision test fixture via an RF cable; the programmable power management module is connected to the power interface of the precision test fixture via a low-voltage DC cable; the precision test fixture has internal electrical connectors that reliably contact the pins of the T / R component under test, achieving a complete path for RF signals, DC power, and control signals. The intelligent diagnostics and fault location module and the integrated database module, as software processes running within the main control module, interact with each other through the main control module's memory and storage resources.

[0015] Furthermore, the preliminary analysis results from the intelligent diagnosis and fault location module can be fed back to the main control module in real time. Based on the feedback, the main control module can dynamically adjust subsequent test plans. For example, when an abnormality is initially determined in the transmission channel, the system will automatically add retesting points for transmission power, harmonics, and VSWR, and adjust the test step to obtain more refined fault characteristic data.

[0016] Furthermore, the integrated database module not only stores the results, but its accumulated historical data can also train and optimize the fault knowledge base of the intelligent diagnosis and fault location module, improving the accuracy and efficiency of fault location over time. The raw data collected by the RF testing module and the programmable power management module corroborate the analysis results of the intelligent diagnosis and fault location module, together forming a complete chain of fault evidence.

[0017] Furthermore, the rapid switching capability of the multi-channel RF switching matrix, combined with the hierarchical diagnostic strategy of the intelligent diagnostic and fault location module, enables rapid traversal and fault isolation of the complex network topology within the T / R component. The high reliability of the precision test fixture ensures the validity of the hardware test data, providing a solid foundation for the intelligent analysis of the intelligent diagnostic and fault location module.

[0018] Compared with the prior art, the beneficial effects of the present invention are: (1) The system defines and controls the test process based on the test sequence retrieved from the comprehensive database module through the main control module, and with the help of the multi-channel RF switching matrix, it realizes the full automation of the process from test path switching, instrument configuration, data acquisition to result interpretation, reducing the complete test time of a single T / R component from several hours of traditional manual testing to several minutes, greatly improving the efficiency of production and maintenance support; (2) The integrated RF test module can fully cover all key RF indicators of T / R components, including static S-parameters based on vector network analysis and dynamic performance indicators based on spectrum analysis. Combined with the programmable power management module, it can fully simulate the actual working state of the components, ensuring the comprehensiveness and accuracy of the test. (3) The core advantage of this invention lies in the intelligent diagnosis and fault location module. The intelligent diagnosis and fault location module can intelligently analyze and locate faults based on test data. By adopting a hierarchical diagnosis strategy, it can achieve accurate fault location from the component level to the module level and then to the component level, which greatly shortens the fault diagnosis and repair time; (4) By replacing different precision test fixtures and loading the corresponding T / R component models and test standards into the integrated database, the system can flexibly adapt to different models and specifications of airborne radar T / R components, and has good versatility.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] Example:

[0023] Please see Figures 1-3 The integrated intelligent detection and fault location system for airborne radar T / R components in this embodiment includes a main control module 1, an RF test module 2, a multi-channel RF switching matrix 3, a precision test fixture 4, a programmable power management module 5, an intelligent diagnosis and fault location module 6, and an integrated database module 7.

[0024] In this embodiment, the main control module 1 is implemented using a high-performance industrial control computer. Its hardware configuration includes DDR4 memory, a solid-state drive, and I / O interfaces for communication (such as PCIe, USB, and Gigabit Ethernet ports). Internally, the main control module 1 runs an intelligent diagnostic and fault location module 6 and a comprehensive database module 7. The main control module 1 is connected to the RF test module 2 and the programmable power management module 5 via a PCIe bus to achieve high-speed data communication. The main control module 1 connects to the multi-channel RF switching matrix 3 via a USB interface to send path switching commands. The main control module 1 uses a Gigabit Ethernet port to connect to the enterprise LAN, supporting remote distribution of test tasks and uploading of test reports.

[0025] The core function of the main control module 1 is to automatically schedule and control the entire testing process based on the test sequence retrieved from the integrated database module 7. The main control module 1 runs a graphical user interface (GUI). Operators use the GUI to select the model of the T / R component under test, set test parameters (such as test frequency range, power level, and temperature point), and then start the test. The main control module 1 parses the instructions from the GUI and generates a series of control commands based on the corresponding test sequence retrieved from the integrated database module 7. This test sequence defines the preset timing and instructions for each module's operation. The main control module 1 sends these commands sequentially to the RF test module 2, the multi-channel RF switching matrix 3, and the programmable power management module 5 according to the preset timing in the test sequence, and receives test data and status information returned by these modules in real time. All data is temporarily stored in DDR4 memory. After a test item is completed, it is packaged together with the analysis results from the intelligent diagnostics and fault location module 6 and stored in the integrated database module 7.

[0026] The RF test module 2 is responsible for performing all RF-related excitation and measurement tasks. In this embodiment, the RF test module 2 includes two core units: a vector network analysis unit 21 and a spectrum and power analysis unit 22.

[0027] The vector network analysis unit 21 is built based on high-speed analog-to-digital converters, digital-to-analog converters, and digital down-conversion and digital up-conversion technologies, with a frequency coverage range of 0.1-20GHz. The vector network analysis unit 21 accurately measures the S-parameters of the T / R module, including transmit gain, receive gain, insertion loss, input VSWR, and output VSWR. Under the unified scheduling of the main control module 1, the system sends digital control commands to the phase shifters and attenuators inside the T / R module through the precision test fixture 4, changing the operating states of the phase shifters and attenuators, enabling the vector network analysis unit 21 to further measure the phase shift accuracy and attenuation accuracy of the phase shifters and attenuators.

[0028] The spectrum and power analysis unit 22 is also built based on high-speed analog-to-digital converters, digital-to-analog converters, and digital down-conversion and digital up-conversion technologies, and has fast Fourier transform analysis capabilities. The spectrum and power analysis unit 22 measures the transmit power, 1dB compression point, harmonic rejection ratio, and spurious emissions of the T / R module in the transmit state, and the noise figure in the receive state.

[0029] The RF test module 2 has two RF ports (Port1 and Port2), which are connected to the two input ports of the multi-channel RF switching matrix 3 via a highly shielded, low-loss RF coaxial cable. The main control module 1 configures the operating mode, frequency, and power of the vector network analysis unit 21 and the spectrum and power analysis unit 22 via the PCIe bus, and reads the measurement results of the vector network analysis unit 21 and the spectrum and power analysis unit 22.

[0030] The multi-channel RF switching matrix 3 is a key component for achieving test automation. In this embodiment, the multi-channel RF switching matrix 3 is a combination of single-pole multi-throw (SPMD) switch arrays, connecting one RF test port to multiple ports under test. The multi-channel RF switching matrix 3 includes 2 input ports (IN1, IN2) and 16 output ports (OUT1 ~ OUT16). IN1 is connected to Port1 of the RF test module 2, and IN2 is connected to Port2. OUT1 to OUT16 are connected to the RF interface of the precision test fixture 4.

[0031] The multi-channel RF switching matrix 3 employs solid-state PIN diode switches, offering advantages such as fast switching speed (microsecond level), long lifespan, and good repeatability. The multi-channel RF switching matrix 3 integrates a microcontroller, which receives commands from the main control module 1 via a USB interface. The command format includes the switch channel number; for example, the command "SWITCH IN1 TOOUT5" instructs the microcontroller to control the corresponding drive circuit, closing the switch connecting IN1 and OUT5 while simultaneously opening other switches connected to IN1.

[0032] When executing test steps, the main control module 1 generates corresponding path switching commands based on the channel of the T / R component to be tested (e.g., the third transmit channel). For example, to test the gain and insertion loss of this channel, the main control module 1 first sends a command to switch IN1 to the OUT port connected to the input of this channel, and then switches IN2 to the OUT port connected to the output of this channel. After the path is established, the main control module 1 then commands the vector network analysis unit 21 of the RF test module 2 to perform S-parameter measurements. This "path first, measurement later" logic ensures the correctness and safety of the test.

[0033] The precision test fixture 4 is the physical interface between the T / R component under test and the test system. It supports, fixes, and provides a low-loss, high-isolation RF signal transmission channel, as well as a stable DC power supply and control signal interface for the T / R component under test.

[0034] The programmable power management module 5 simulates the real power supply environment of the T / R components in a radar system. In this embodiment, the programmable power management module 5 is a multi-channel programmable DC power supply, providing 8 independent voltage outputs. Each voltage is programmed in 1mV increments within the 0-15V range, with a maximum current of 5A. Each channel integrates a high-precision voltmeter and ammeter, achieving a measurement accuracy of 0.1%.

[0035] The programmable power management module 5 receives control commands from the main control module 1 via the PCIe bus. Internally, the programmable power management module 5 contains a digital signal processor (DSP). After parsing the commands, the DSP controls the digital-to-analog converter (DAC) to output a corresponding reference voltage. Through a feedback loop, it adjusts the power output stage to stabilize the voltage at the set value. The DAC within the programmable power management module 5 continuously samples the actual output voltage and load current, and uploads these data to the main control module 1 via the PCIe bus. The main control module 1 uses the actual output voltage and load current as crucial indicators of the T / R component's operational status (e.g., abnormally high current may indicate an internal short circuit).

[0036] The intelligent diagnosis and fault location module 6 runs as software on the main control module 1. Its workflow is as follows: Step 1: Data Preprocessing: The intelligent diagnosis and fault location module 6 receives the raw data collected by the main control module 1 from the RF test module 2 and the programmable power management module 5, and performs filtering, normalization and error compensation preprocessing. Step 2: Compare with standard data: Retrieve the "gold standard" data, i.e., ideal performance parameters, from the integrated database module 7, which are completely consistent with the model of the T / R component currently being tested. Compare the preprocessed measured data with the standard data item by item and calculate the deviation; Step 3, Level 1 Diagnosis (Component Level): If the deviations of all key indicators are within the allowable tolerance range, the T / R component is judged as "qualified". If any key indicator exceeds the tolerance, it is judged as "unqualified" and proceeds to Level 2 Diagnosis; Step 4, Secondary Diagnosis (Module Level): Based on the type of out-of-tolerance indicator, initially pinpoint the faulty functional module. For example: if the transmit power, transmit gain, and 1dB compression point indicators are unqualified, the initial fault is located in the transmit channel module; if the noise figure and receive gain indicators are unqualified, the initial fault is located in the receive channel module; if the phase shift accuracy and attenuation accuracy are unqualified, the initial fault is located in the beam control module, which is a specific implementation of the control logic module and includes phase shifters and attenuators; if the power supply monitoring current is abnormal, the initial fault is located in the programmable power management module 5. Step 5, Level 3 Diagnosis (Component Level): After identifying the faulty module, the system automatically executes targeted and refined testing sub-processes. For example, for a faulty transmit channel module, the system uses the multi-channel RF switching matrix 3 and the vector network analysis unit 21 of the RF test module 2 to further test the input and output matching and gain flatness of the power amplifier in the transmit channel. Combined with fault cases (such as "low power amplifier gain and high output VSWR, the most likely fault is the failure of the power amplifier chip itself"), the system finally gives the most likely location of the faulty component, such as "the power amplifier chip in the transmit channel has failed." Step Six: Feedback and Adaptation: The diagnostic results (including fault level and suspected location) are immediately fed back to the main control module 1. The main control module 1 dynamically adjusts the test sequence based on the feedback. For example, if the intelligent diagnosis and fault location module 6 determines that multiple channels have power supply problems, the main control module 1 will skip the RF performance tests for these channels and directly command the programmable power management module 5 to perform power ripple and dynamic response tests, quickly identifying the root cause of the fault, avoiding invalid RF tests, and achieving optimal allocation of test resources.

[0037] The integrated database module 7 is implemented using a relational database (such as MySQL) and stored on the solid-state drive of the main control module 1. Its data table structure is designed as follows: Component Information Table: Stores basic information about the T / R components, including model and serial number; Standard parameter table: Stores the "gold standard" performance parameters and tolerance ranges of each T / R component model under standard test conditions; Raw Test Data Table: Stores all raw measurement data for each test, and is associated with the component information table via serial number; Diagnostic Result Table: Stores each diagnostic conclusion given by the intelligent diagnostic and fault location module 6, including qualified status, unqualified status, faulty module, and suspected component; The fault knowledge base table is a continuously growing expert knowledge base that stores the mapping relationship between "fault phenomena - test data characteristics - fault causes," serving as the basis for reasoning by the intelligent diagnosis and fault location module 6. The data in the fault knowledge base table comes from historical fault cases and expert experience.

[0038] The integrated database module 7 serves as a link between the past, present, and future. It provides comparison standards and reasoning basis for the intelligent diagnosis and fault location module 6. Each new test and diagnostic result feeds back into the database, especially new fault cases, which enrich the fault knowledge base. This allows the entire system's diagnostic capabilities to continuously improve over time, achieving data-driven self-evolution.

[0039] The specific implementation method of this embodiment is as follows: S1. System Initialization and Task Configuration: The operator starts the system, and the main control module 1 performs a self-test. On the graphical user interface, the operator selects the model information of the T / R component under test and sets the test parameters (such as temperature and frequency range). S2. Install the T / R component under test: Install the T / R component under test onto the precision test fixture 4 and establish a reliable electrical connection; S3. Start the comprehensive test process: The main control module 1 retrieves the corresponding test sequence and standard parameters from the comprehensive database module 7 according to the model of the T / R component under test, and the test begins; S4. Power supply and status monitoring: The main control module 1 commands the programmable power management module 5 to supply power to the T / R component according to the preset timing sequence, and monitors the voltage and current of each circuit in real time to determine whether there are hard faults such as short circuits and overcurrents; S5. Automatic RF performance testing: The main control module 1 controls the multi-channel RF switching matrix 3 to connect the RF test module 2 to each RF channel of the T / R component in sequence, and commands the RF test module 2 to perform preset measurements such as S-parameters, power, and noise figure; S6. Data Acquisition and Real-time Analysis: Main control module 1 acquires test data and power monitoring data in real time; S7. Intelligent Diagnosis and Fault Location: The intelligent diagnosis and fault location module 6 analyzes all data, executes a hierarchical diagnosis process, and provides preliminary diagnostic conclusions; S8. Closed-loop feedback and adaptive adjustment: The diagnostic conclusion is fed back to the main control module 1. If the diagnosis is normal, the process jumps to S10. If the diagnosis is a fault, the main control module 1 dynamically adjusts the test sequence according to the fault type, generates a supplementary test sequence, and executes targeted refined tests (S9) to obtain more accurate fault location information; S9. Refined Testing and Secondary Diagnosis: Execute the supplementary test sequence generated in S8. The intelligent diagnosis and fault location module 6 combines the new data to perform secondary diagnosis and finally give a fault location report accurate to the component level. S10. Generate and store test report: The main control module 1 integrates all test data and diagnostic results, generates a standardized and detailed test report, and stores the test report in the comprehensive database module 7 after associating it with the serial number of the tested T / R component. S11. Test complete: The test process is complete, and the system prompts the operator to remove the T / R component under test.

[0040] Through the above process, this invention achieves efficient, comprehensive, and intelligent detection and fault location of airborne radar T / R components, significantly improving the production support level and maintenance efficiency of airborne radar systems.

[0041] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
