Description

Technical Field

[0001] This invention relates to the field of aircraft manufacturing technology, specifically to a system for setting test parameters for aircraft power supply characteristics. Background Technology

[0002] In aircraft research and development and maintenance, power supply characteristic testing is a crucial step in verifying the reliability of airborne equipment in complex power grid environments. Such tests simulate various harsh operating conditions, including normal power supply, power outages, voltage spikes, and voltage distortion (harmonics), to verify whether the equipment meets aviation standards.

[0003] Currently, the testing systems and methods commonly used in the industry have significant shortcomings. Traditional testing platforms typically rely on the manual assembly and connection of numerous discrete instruments (such as programmable power supplies, load banks, spike generators, harmonic injection devices, etc.). When performing different tests, technicians must manually complete arduous tasks such as physical wiring, instrument parameter settings, and switching based on complex circuit diagrams. This operating mode is not only extremely inefficient and time-consuming, but more seriously, frequent manual operations are prone to introducing human errors such as wiring mistakes and poor connections, leading to unreliable test results and potentially causing safety accidents due to incorrect connection of high-voltage lines. Furthermore, manual systems struggle to ensure consistency in test procedures and parameter configurations, resulting in poor comparability of test data from different batches or personnel, and cannot achieve automated sequential execution and remote monitoring of the testing process.

[0004] Therefore, there is an urgent need for an aircraft power supply characteristic test parameter setting system that can integrate multiple test functions, achieve one-click rapid and accurate configuration, and has high reliability and automation. Summary of the Invention

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments: Example 1, please refer to Figures 1-2 An aircraft power supply characteristic test parameter setting system includes: a control component for issuing control commands; and a high-voltage component for realizing power output. The control component includes a microcontroller for storing and executing predetermined programs and issuing program commands. The high-voltage component includes a four-phase power supply and a contactor assembly.

This system constructs a clear and precise integrated "command-power distribution" test platform. The system architecture is clearly divided into a control layer and an execution layer: the control layer, with a microprocessor at its core, integrates various functional switches and communication management modules, responsible for the intelligent parsing and issuance of instructions; the execution layer uses a four-phase power supply as its power source, and through specific electrical connections and combinations of 14 contactors (from the first contactor 1 to the fourteenth contactor 14), it quickly constructs actual power distribution circuits that meet the requirements of different testing standards. The effectiveness, creativity, and superiority of each module are specifically reflected in: the microcontroller, as the control core, realizes the programming and automation of the testing process, fundamentally ensuring the consistency and repeatability of operations, and demonstrating high creativity. The four-phase power supply (A, B, C, N phases) provides a wide-range, adjustable power supply of 0-600V / 0-32A, laying the foundation for testing. The modular contactors, from the first contactor 1 to the fourteenth contactor 14, are crucial to the system's operation. Their innovation lies in their ability to flexibly, reliably, and quickly switch between dozens of test conditions, such as shoot-through, load-bearing, spike injection, or harmonic injection, through pre-defined circuit logic (e.g., an inductor between the third contactor 3 and the fourth contactor 4, and a capacitor between the fifth contactor 5) and specific connection methods with the power supply phases (A, B, C, N).

Microcontrollers, programmable switches, direct-connect switches, power interruption switches, DC single-phase AC delta-connected voltage spike switches, and three-phase Y-connected voltage spike switches are also included. The system includes a voltage spike switch for three-phase delta connection, a voltage distortion spectrum calibration switch for three-phase AC voltage, distortion spectrum calibration switch for three-phase delta connection, voltage distortion spectrum calibration switch for three-phase Y connection, indicator light control switch, DC single-phase AC voltage distortion spectrum test switch, three-phase delta connection voltage distortion spectrum test switch, three-phase Y connection voltage distortion spectrum test switch, TCP / IP communication module, temperature sensor module, PWM fan control module, and multiple contactor control modules. The multiple contactor control modules are connected to contactors respectively. The components are interconnected. The high-voltage components also include five 50uH inductors and seven 10uF capacitors. The output of the four-phase power supply is electrically connected to the first contactor 1. The A and N phases of the four-phase power supply are electrically connected to the input of the third contactor 3. The third contactor 3 and the fourth contactor 4 are electrically connected through two 50uH inductors. The output of the third contactor 3 is grounded through a 10uF capacitor. The output of the fourth contactor 4 is electrically connected to the A and N phases of the four-phase power supply. The four-phase power supply is electrically connected to the input of the second contactor 2. Three of the output terminals of contactor 2 are electrically connected to phases A, B, and C of the four-phase power supply via three 50uH inductors, respectively. The remaining output terminal of contactor 2 is electrically connected to the N phase of the four-phase power supply. The input terminal of contactor 5 is electrically connected to phases A, B, and C of the four-phase power supply via three 10uF capacitors. The output terminal of contactor 5 is electrically connected to the N phase of the four-phase power supply. The input terminal of contactor 6 is electrically connected to the N phase of the four-phase power supply, and the output terminal of contactor 6 is grounded. Two of the input terminals of contactor 7 are connected to two 10uF capacitors. A 10uF capacitor is electrically connected to phase A of the four-phase power supply. The remaining input terminal of the seventh contactor 7 is electrically connected to phase B of the four-phase power supply through a 10uF capacitor. Two of the output terminals of the seventh contactor 7 are electrically connected to phase C of the four-phase power supply. The remaining output terminal of the seventh contactor 7 is electrically connected to phase B of the four-phase power supply. The input terminals of the eighth contactor 8, ninth contactor 9, eleventh contactor 11, and twelfth contactor 12 are electrically connected to phases A, B, and C of the four-phase power supply.

Through a precise collaborative architecture of "weak current control and strong current execution," automated, rapid, and accurate configuration of various aviation power supply test scenarios is achieved. The system architecture is clearly divided into two main layers: a control component with a microcontroller as its brain, and a strong current component consisting of the four-phase power supply and contactors 1 through 14.

[0029] Specifically, the innovation of the control component lies in its integration of a highly specialized group of functional switches (such as a DC single-phase AC delta connection voltage spike switch and a three-phase Y connection voltage distortion spectrum test switch), and intelligent management and signal interconnection through a microcontroller, TCP / IP communication module, and temperature sensor module. This allows complex test logic (such as calibrating or testing the voltage distortion spectrum of different connections) to be encoded into preset instructions and triggered with a single button, replacing the traditional cumbersome manual judgment and wiring operations, and offering significant advantages in terms of ease of operation, repeatability, and accuracy. The innovation of the power supply component is reflected in its sophisticated topology and component configuration. The four-phase power supply provides a wide range of base power for the system. Crucially, each contactor from the first contactor 1 to the fourteenth contactor 14 is assigned a specific circuit role, and through specific connections with components such as five 50uH inductors and seven 10uF capacitors (for example, the series inductor between the third contactor 3 and the fourth contactor 4 forms a filter branch, and the fifth contactor 5 is connected to a three-phase capacitor), they collectively form a dynamically reconfigurable power distribution network. For example, the eighth contactor 8 and the twelfth contactor 12 are defined as power amplifier access points, and the ninth contactor 9 and the eleventh contactor 11 are defined as spike source access points. This modular and role-predefined design enables the system to quickly and reliably build the precise electrical environment required for various voltage spikes and spectrum tests, from shoot-through and power interruption to various voltage spikes. Its comprehensive test coverage, speed of mode switching, and optimization of hardware configuration demonstrate outstanding technical advantages.

[0030] Example 2, please refer to Figures 1-2 A parameter setting system for aircraft power supply characteristics testing includes a microcontroller that enables rapid and accurate configuration of test scenarios through a variety of preset instructions. These instructions mainly include function setting instructions, contactor setting instructions, and query instructions.

[0031] The function setting instructions are advanced compound instructions; a single instruction completes the configuration of a specific test circuit. The microcontroller has a pre-stored instruction mapping table. When the Set201 character sequence is received via the TCP / IP module, the parsing module maps it to a specific bit in the control register, setting it high. This drives the I / O ports to output a high level to the first, tenth, thirteenth, and fourteenth contactors. When the microcontroller receives such instructions, it automatically controls the corresponding contactor control modules to connect or disconnect the contactors, thus forming the required electrical path. Specifically, this includes: The Set201 command is used to configure a power outage test scenario and connect a load. After execution, it controls the first contactor 1, the tenth contactor 10, the thirteenth contactor 13, and the fourteenth contactor 14 to be connected, while the remaining contactors are disconnected.

[0032] SETPASS command: Used to configure a pass-through test scenario. After execution, it controls the first contactor 1, the tenth contactor 10, and the fourteenth contactor 14 to be turned on, while the remaining contactors are turned off.

[0033] SET106_AC3_Y instruction: Used to configure the AC three-phase Y-connection voltage spike test scenario and connect the capacitor. After execution, it controls the first contactor 1, the fifth contactor 5, the ninth contactor 9, the eleventh contactor 11, and the fourteenth contactor 14 to be turned on, and the remaining contactors to be turned off.

[0034] The SET106_AC3_THRI instruction is used to configure the AC three-phase delta connection voltage spike test scenario and connect a capacitor. After execution, it controls the first contactor 1, the seventh contactor 7, the ninth contactor 9, the eleventh contactor 11, and the fourteenth contactor 14 to be turned on, while the remaining contactors are turned off.

[0035] The SET103CALI_DC_ACSINGLE instruction is used to configure a DC or AC single-phase voltage distortion spectrum calibration scenario and connect an inductive-capacitive load. After execution, it controls the third contactor 3, the fourth contactor 4, the fifth contactor 5, the eighth contactor 8, the twelfth contactor 12, and the thirteenth contactor 13 to be turned on, while the remaining contactors are turned off.

[0036] The SET103CALI_DC_AC3Y instruction is used to configure the AC three-phase Y-connection voltage distortion spectrum calibration scenario and connect an inductive and capacitive load. After execution, it controls the second contactor 2, the fifth contactor 5, the eighth contactor 8, the twelfth contactor 12, and the thirteenth contactor 13 to be turned on, while the remaining contactors are turned off.

[0037] The SET103CALI_DC_AC3THRI instruction is used to configure a voltage distortion spectrum calibration scenario for a three-phase delta connection and to connect an inductive-capacitive load. After execution, it controls the second contactor 2, the seventh contactor 7, the eighth contactor 8, the twelfth contactor 12, and the thirteenth contactor 13 to be turned on, while the remaining contactors are turned off.

[0038] The SET103CALI_DC_ACSINGLE instruction is used to configure a DC or AC single-phase voltage distortion spectrum test scenario and connect an inductive and capacitive load. After execution, it controls the third contactor 3, the fourth contactor 4, the fifth contactor 5, the eighth contactor 8, the twelfth contactor 12, and the fourteenth contactor 14 to be turned on, while the remaining contactors are turned off.

[0039] The SET103CALI_DC_AC3Y instruction is used to configure the AC three-phase Y-connection voltage distortion spectrum test scenario and connect an inductive and capacitive load. After execution, it controls the second contactor 2, the fifth contactor 5, the eighth contactor 8, the twelfth contactor 12, and the fourteenth contactor 14 to be turned on, while the remaining contactors are turned off.

[0040] The SET103CALI_DC_AC3THRI instruction is used to configure an AC three-phase delta connection voltage distortion spectrum test scenario and connect an inductive-capacitive load. After execution, it controls the second contactor 2, the seventh contactor 7, the eighth contactor 8, the twelfth contactor 12, and the fourteenth contactor 14 to be turned on, while the remaining contactors are turned off.

[0041] Contactor setting instructions are low-level control instructions used to operate individual contactors independently. They include the SETXXRELAYOFF instruction (sets the XXth contactor to OFF) and the SETXXRELAYON instruction (sets the XXth contactor to ON), where "XX" represents the specific contactor number.

[0042] The query command is the RELAY? command, used to query the current on / off status of all contactors in the system. The system returns a binary sequence as a response, where each bit in the sequence represents a contactor in sequence (e.g., the first bit represents contactor 1). The number "0" indicates that the contactor is in the off state, and the number "1" indicates that the contactor is in the on state.

[0043] All contactors in the system are normally open, remaining open when no power is applied, which enhances the inherent safety of the system.

[0044] Working principle: Step 1: System Initialization and Self-Test After the system is powered on, the microcontroller starts and executes a self-test program. It receives remote commands via the TCP / IP communication module or calls preset programs from internal storage, while the temperature sensor module begins monitoring the internal system temperature. All contactors are in a default open state due to their normally open design, and the PWM fan control module adjusts cooling according to the temperature. The microcontroller sends a `RELAY?` query command to verify that all contactors are initially open, ensuring a safe start.

[0045] Step Two: Test Scenario Configuration and Command Parsing According to the test requirements (such as performing "AC three-phase Y-connection voltage distortion spectrum test"), the operator or host computer sends the corresponding advanced function setting command to the system, such as SET103CALI_DC_AC3Y. After receiving the command, the microcontroller parses it, determines the test circuit topology to be constructed, and calculates the contactor combination to be operated (in this example, turning on the second contactor 2, the fifth contactor 5, the eighth contactor 8, the twelfth contactor 12, and the fourteenth contactor 14, and turning off all other contactors).

[0046] Step 3: Control signal transmission and high-voltage circuit reconfiguration The microcontroller sends control signals to the corresponding contactor control modules via a signal network. Each module drives its designated contactor to perform on / off actions. For example, when the second contactor 2 closes, three phases (A, B, and C) of the four-phase power supply are connected to the system through three 50uH inductors; when the fifth contactor 5 closes, three 10uF capacitors are connected between the three phases and the N phase to form a filter network; when the eighth contactor 8 and the twelfth contactor 12 close, they are connected to the power amplifier source; and when the fourteenth contactor 14 closes, the output is turned on. Simultaneously, unrelated contactors remain open, such as the first contactor 1 and the thirteenth contactor 13, all of which are disconnected in this mode.

[0047] Step 4: Test Execution and Monitoring Once the required high-voltage circuit is constructed, the four-phase power supply outputs a specific voltage and current (0-600V, 0-32A) according to the microcontroller's parameter settings. The test signal is applied through the reconstructed path (power supply, inductor, test point, capacitor network, output). Throughout the test, the microcontroller continuously monitors the temperature rise via a temperature sensor module, uploads real-time status and data via a TCP / IP communication module, and displays the control switch status via indicator lights. The system performs calibration or testing operations under this stable configuration.

[0048] Step 5: Switch test mode or shut down the system When switching to another test mode is required (e.g., switching to the "power interruption" test), the process repeats steps 2-4: The system receives a new instruction (e.g., Set201), the microcontroller parses it, first disconnects all contactors in the current mode, and then connects the first contactor 1, the tenth contactor 10, the thirteenth contactor 13, and the fourteenth contactor 14 as required by the new instruction, thereby quickly switching the circuit topology from the spectrum test loop to the power interruption test loop under load. After all tests are completed, a global disconnect command is sent or the power is turned off, all contactors return to their normally open / disconnected state, and the system is safely shut down.

[0049] The core of this workflow lies in transforming complex hardware wiring logic into simple software instructions through a microcontroller, and using a contactor control module to control the first contactor 1 to the fourteenth contactor 14 in a group, dynamically reorganizing the high-voltage network composed of power supply, inductor, capacitor, etc., to achieve one-click, fast, and accurate switching and full-process monitoring of multiple test scenarios.

[0050] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the protection scope of the present invention.
