Description

Technical Field

[0001] This application belongs to the field of airborne testing technology, and in particular relates to an intelligent airborne testing system. Background Technology

[0002] The integrated testing of electronic equipment is indispensable in current aviation, aerospace, vehicle, and weaponry fields. Taking the integrated ground testing of a certain aircraft as an example, it involves multiple avionics subsystems such as atmospheric data systems, integrated navigation systems, communication, navigation and identification systems, and electronic self-defense. The existing test cable junctions use terminals on the entire cable section for connection. A wiring diagram must be confirmed in advance, and junction construction must be carried out according to the diagram. If cable modifications or changes to the wiring diagram occur, the diagram must be consulted again, the corresponding junction point located, and the entire cable modified, which is time-consuming and labor-intensive. Furthermore, the existing test cable junction system is essentially unusable for integrated testing tasks under different conditions on the same platform.

[0003] Moreover, with the increase in models, including new research and development or modification, the airborne test environment needs to be repeatedly constructed or maintained for a long time. This results in problems such as large workload for new construction, inability to reuse existing equipment, difficulty in wiring and maintenance, occupation of test sites, unreasonable power consumption distribution of power distribution equipment, and insufficient storage and utilization of test data. Summary of the Invention

[0011] Power is connected to the intelligent distribution box;

[0012] The output ports of the intelligent power distribution box are connected to the airborne avionics subsystem. Specifically, it is used to monitor and identify the power consumption requirements of the connected airborne avionics subsystem in real time through sensors, and automatically adjust the current distribution of each output port according to the power consumption requirements.

[0013] The host computer software measures and monitors environmental parameters such as voltage, current, temperature, and humidity via a local area network, and remotely monitors, controls, and manages the power supply requirements of the airborne avionics subsystems.

[0037] The intelligent airborne testing system provided by the present invention will be explained below with reference to the accompanying drawings.

[0038] Please see Figure 1-8 This invention proposes an intelligent airborne testing system, comprising: a power distribution module, a wiring module, a bus simulation and monitoring module, a data storage module, and a data playback and fault diagnosis module. The overall architecture of the intelligent airborne testing system is shown below. Figure 1 .

[0039] Previous testing systems used traditional power distribution methods, which had a single distribution mode and could not be flexibly configured according to the needs of different equipment, often resulting in problems such as insufficient number of power distribution channels and power mismatch. The power distribution module proposed in this invention has intelligent features, which can automatically adjust and distribute current according to the power consumption of the equipment, ensuring that each device receives a stable and adequate power supply.

[0040] Specifically, the power distribution module includes: a power supply, an intelligent distribution box, and host computer software. The power supply primarily provides voltage input. The intelligent distribution box automatically adjusts the current distribution of each output port through sensors and built-in algorithms to meet the power supply requirements of different devices, enabling real-time monitoring and identification of the power consumption needs of connected devices. The host computer software measures and monitors parameters such as voltage, current, and temperature via a local area network, and remotely monitors, controls, and manages the power supply needs of the devices.

[0041] Traditional wiring methods primarily employ cable relays and junction boxes, requiring a large number of junction box terminals and resulting in complex wiring, poor maintainability, and significant costs for future rewiring. This invention proposes a wiring module comprising an automatic wiring module, automatic wiring software, and a signal separation surface. During testing across multiple models, different signal line connection methods correspond to different signal connection topology information. The signal separation surface performs image recognition and acquisition on the onboard equipment plugs, converting it into a signal wiring matrix. An actuator positions and presses the channel connector caps to connect and disconnect the channels. The working principle of the wiring module is described in [link to documentation]. Figure 2 The working principle of the signal separation surface is shown in [link to documentation]. Figure 3 .

[0042] The automatic wiring device includes a signal wiring matrix and an actuator. The wiring matrix consists of source and destination terminals, forming junction points at the intersections of the horizontal and vertical arrays. Each junction point has a connector cap. The actuator consists of three guide rails (X, Y, and Z) and a drive device. The drive device receives position information generated by the automatic wiring software, positions itself to the junction point in the X and Y directions, and presses the connector cap in the Z direction to connect the source and destination terminals, and can also disconnect them. The automatic wiring software reads the wiring relationship table and receives the plug number and pin number of each plug automatically identified by the signal separation panel. It calculates and analyzes the position information in the signal wiring matrix and detects missing pins in the plugs. See the top and left views of the automatic wiring device. Figure 4 and Figure 5 .

[0043] The bus simulation monitoring module includes board resources, simulation component switching devices, and channel expansion arrays. Board resources include various bus boards, which are scheduled through a unified interface and encapsulated using the DDS communication protocol.

[0044] The simulation / real component switching device connects the real component input signals and the simulation component input signals to the avionics test bus via relays. When a relay connected to the real component input signal receives a control command, it will connect the real component input signal; when a relay connected to the simulation component input signal receives a control command, it will connect the simulation component input signal. The working principle of the simulation / real component switching device is described in [link to documentation]. Figure 6 .

[0045] Channel expansion arrays are used to expand channels by 4x, 16x, or even higher. A single board (taking the ARI NC429 board as an example, which only has 16 or 32 channels for simulation and monitoring) can achieve simulation and monitoring of 128 channels or more. This allows for flexible configuration of board simulation and monitoring resources, improving board resource utilization. See the schematic diagram of the channel expansion array. Figure 7 .

[0046] The data storage module includes data storage hardware and software. It collects data from airborne equipment via a bus emulation monitor, parses the data, and then stores it. See the schematic diagram of the data storage module. Figure 8 .

[0047] The data playback and fault diagnosis module plays back and analyzes the stored data and injects the data into the test equipment to facilitate the analysis and diagnosis of problems.
