Description

Technical Field

[0001] The present application belongs to the technical field of airborne test and experiment, and in particular, relates to an intelligent airborne test system. Background Art

[0002] The existing fields of aviation, aerospace, vehicles, weapons, etc. are inseparable from the integrated joint test of electronic equipment. Taking the ground integrated joint test of a certain aircraft as an example, it involves multiple avionics subsystems such as atmospheric data system, integrated navigation system, communication navigation identification system, and electronic self-defense. The existing test cable junction uses the entire cable to connect the terminal at the cable junction. It is necessary to confirm the wiring relationship table in advance and perform the junction construction according to the wiring relationship table. If the cable or wiring relationship table is changed, it is necessary to check the wiring relationship table again. After finding the corresponding junction point, modify the entire cable, which is time-consuming and laborious. If you encounter joint test tasks in different states under the same model platform, the original test cable junction system can basically not be reused.

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

[0037] The intelligent airborne test system provided by the present invention is explained below in conjunction with the accompanying drawings.

[0038] See also Figure 1-8 The present invention proposes an intelligent airborne test system, including: a power distribution module, a wiring module, a bus simulation monitoring module, a data storage module, and a data playback and fault diagnosis module. The overall architecture of the intelligent airborne test system is shown in Figure 1 .

[0039] In the past, the test system used the traditional power distribution method, which had a single power distribution mode and could not be flexibly configured according to the needs of different devices. Problems such as insufficient number of power distribution channels and mismatched power distribution often occurred. The power distribution module proposed in the present invention has the characteristics of intelligence, and can automatically adjust and distribute current according to the power consumption of the equipment, ensuring that each device can obtain a stable and appropriate power supply.

[0040] Specifically, the power distribution module includes: power supply, intelligent distribution box, and host computer software. The power supply is mainly used to provide voltage input. The intelligent distribution box automatically adjusts the current distribution of each output port through sensors and built-in algorithm logic to meet the power supply requirements of different devices, and realizes real-time monitoring and identification of the power consumption requirements of connected devices. The host computer software measures and monitors parameters such as voltage, current, and temperature through the local area network, and remotely monitors, controls, and manages the power supply requirements of the equipment.

[0041] In the past, wiring was mainly done by cable transfer and connection, which required a large number of connection terminals, complicated wiring, poor maintainability, and huge costs for later wiring changes. The present invention proposes a wiring module, including an automatic wiring module, an automatic wiring software signal separation interface, and when testing between multiple models, different signal line connection methods correspond to a signal connection topology information. The signal separation interface performs image recognition and collection on the airborne device plug and converts it into a signal wiring matrix. The channel wiring cap is positioned and pressed by an actuator to connect and disconnect the channel. The working principle of the wiring module is shown in Figure 2 , the working principle of the signal separation surface is shown in Figure 3 .

[0042] The automatic wiring equipment includes a signal wiring matrix and an actuator. The wiring matrix consists of source terminals and destination terminals. Junctions are formed at the intersection of the horizontal and vertical arrays, and each junction has a plug cap. The actuator consists of three guide rails, X, Y, and Z, and a drive device. The drive device receives the position information generated by the automatic wiring software to locate the junction in the X and Y directions, and presses the plug cap in the Z direction to connect the source terminal and the destination terminal, and 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, calculates and analyzes the position information in the signal wiring matrix, and detects missing pins in the plug. The top view and left view of the automatic wiring equipment are shown in Figure 4 and Figure 5 .

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

[0044] The simulation-to-real switching device controls the real input signal and the simulation input signal to be connected to the avionics test bus through relays. When the relay connected to the real input signal receives a control instruction, the real input signal will be connected. When the relay connected to the simulation input signal receives a control instruction, the simulation input signal will be connected. The working principle of the simulation-to-real switching device is shown in Figure 6 .

[0045] Channel expansion array is used to expand channels, achieving 4 times, 16 times or higher expansion. Only one board (for example, ARI NC429 board, which only has 16 or 32 channels of simulation and monitoring) can be used to achieve 128 channels or even more channels of simulation and monitoring. Board simulation and monitoring resources can be flexibly configured to improve board resource utilization. Figure 7 .

[0046] The data storage module includes data storage hardware and software. It collects data from the airborne equipment through the bus simulation monitor, analyzes the data, and then stores the data. Figure 8 .

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