[0002] Aircraft assembly involves docking various aircraft components, installing electronic equipment and devices, and performing functional testing and inspection of various systems and the entire aircraft. Currently, there are two common methods for testing in aircraft assembly: one is for staff to use dedicated test equipment for each device to test it; the other is for the aircraft's own self-test system to test and inspect the aircraft after all systems are assembled. Regardless of which existing technology is used, the testing process in aircraft assembly is relatively complex, and each time point requires manual coordination and processing, resulting in low testing efficiency.

BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Figure 1 FIG2 is a schematic structural diagram of an aircraft assembly test system provided by an embodiment of the present invention. DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0033] At present, aircraft final assembly is characterized by large engineering workload, complex assembly and testing, and there are many interactions between assembly and testing. Aircraft final assembly mainly includes the following parts:

[0034] (1) Full machine docking

[0035] The docking of the entire aircraft includes the docking of various sections that make up the aircraft fuselage, wings, tail, etc.

[0036] (2) Installation and adjustment of power and landing gear

[0037] The power plant is the device that generates the aircraft's flight power, such as the engine and battery. It also includes various movable surfaces, such as flaps, ailerons, and spoilers. The landing gear is used to ensure the aircraft's takeoff, landing, taxiing, and parking. After installation, these devices must be adjusted and tested to ensure they function properly.

[0038] (3) Functional system installation

[0039] The functional systems of an aircraft include flight and life systems. The flight system includes flight control system, hydraulic system, fuel power system, power supply system and communication and navigation system; the life system includes

[0040] Life-saving systems, lighting systems, kitchen systems, water / wastewater systems, etc.

[0041] Functional system installation is to integrate the flight function system and life function system into their own complete systems.

[0042] (4) Whole machine testing and inspection

[0043] Aircraft debugging is to test whether the various functional systems and devices on the aircraft meet the design requirements, quality requirements and usage requirements, and conduct a series of on-board debugging and functional tests to verify the correctness and safety of the installed systems.

[0044] If the testing phase is carried out after the aircraft is assembled, then when a problem occurs with a device or component, the aircraft will need to be disassembled, resulting in a huge waste of human resources and time costs.

[0045] Therefore, the present application proposes an aircraft assembly test system, characterized in that the system includes:

[0046] Assembly module, used to store assembly plans for each aircraft subsystem and equipment and monitor assembly progress;

[0047] Test modules, used to test assembled subsystems and equipment;

[0048] Controller for:

[0049] building a test model according to the assembly plan;

[0050] The assembled subsystems and devices are tested based on the test model and test modules.

[0051] Specifically, because the aircraft assembly test system proposed in this application is for testing during the assembly process of existing aircraft models rather than the development of aircraft, historical assembly data of the corresponding models can be imported, and technical personnel in this field can adjust and modify the historical assembly data based on previous assembly experience, thereby making the historical assembly data more accurate.

[0052] After importing the historical assembly data, the assembly plan for the aircraft to be assembled can be formulated based on the time nodes or work task nodes in the historical assembly data.

[0053] The test module can detect whether the corresponding test equipment is connected to its interface and test the assembled subsystems and equipment through the test equipment.

[0054] In the embodiment of the present application, the controller is specifically configured to:

[0055] Determine the model of the aircraft to be assembled;

[0056] Retrieving a corresponding assembly plan in the assembly module based on the model of the aircraft to be assembled;

[0057] A test model is established according to the assembly plan, wherein the test model includes test nodes corresponding to time nodes in the assembly plan, and the test nodes include test time nodes, tested equipment or tested subsystems, test instruments, test items, test processes, test operation procedures, test operation requirements, and standard performance data.

[0058] In the embodiment of the present application, when establishing the model, the controller further includes determining the constraint relationships between subsystems and between devices in the subsystems, specifically:

[0059] Determine the operating requirements of the subsystem and each device in the subsystem;

[0060] Determine the necessary assembled subsystems and equipment based on the operating requirements of the subsystems and the equipment in them, thereby determining the constraint relationships between subsystems and between the equipment in the subsystems;

[0061] The test nodes in the test model are adjusted according to the constraint relationship.

[0062] Specifically, some subsystems or devices cannot be tested immediately after they are assembled, that is, there is a sequence constraint relationship between subsystems or devices. A certain work task, that is, the test of a certain subsystem or device, must wait until all predecessor tasks are completed before it can begin. In addition, there is also a work task that can contain the constraint relationship of the predecessor task, that is, when testing a certain work task, its predecessor task can be tested at the same time, and then the corresponding device test node can be flexibly advanced, postponed or deleted according to the constraint relationship.

[0063] In an embodiment of the present application, the controller synchronizes the established test model to the test module, so that the test module tests the subsystem or device based on the test model.

[0064] In an embodiment of the present application, the test module further includes a plurality of interface integrations and test instrument information, and the test instrument information includes the number of test instruments and the use status of the test instruments.

[0065] Specifically, there can be multiple test modules, each corresponding to a subsystem. The test module determines the test instruments required for the subsystem or equipment to be tested, as well as the required test items, test processes, test operation procedures, test operation requirements, and standard performance data based on the synchronized test model.

[0066] In an embodiment of the present application, the controller is further configured to:

[0067] Obtaining assembly progress when a test time node in the test model is reached;

[0068] Determine whether the device under test or the subsystem under test at the test time node has been assembled in the assembly progress. If not, the controller issues a prompt message. If yes, proceed to the next step.

[0069] According to the use status of the test instruments, it is determined whether there is an inoperative instrument. If not, the controller issues a prompt message. If so, the corresponding test instrument is called to test the device under test or the subsystem under test.

[0070] Specifically, when the test time node in the test model arrives, the test module and the controller work simultaneously. The test module detects whether the corresponding test instrument is connected, and the controller determines whether the equipment or subsystem to be tested has been assembled. If so, the test is carried out normally. If not, a prompt message is issued to notify the staff, and the staff adjusts the test date.

[0071] In an embodiment of the present application, the assembly module also includes a three-dimensional assembly model, which is specifically a completed assembly model completed according to the assembly plan, wherein the three-dimensional assembly model can be split according to each subsystem or device, and the three-dimensional assembly model contains information about each subsystem or device, and the information includes size information, parameter setting information, interface information and connection information.

[0072] In an embodiment of the present application, the controller is further configured to:

[0073] When the test results are inconsistent with the stated standard performance data,

[0074] The detection information of the subsystem or device under test is compared with the corresponding information in the three-dimensional assembly model to determine the fault point.

[0075] Specifically, the 3D assembly model contains information about every subsystem or device in the aircraft assembly process. When problems arise in the test results, workers can directly query the cause of the problem or determine the fault point through the 3D assembly model. At the same time, the test model also includes the test process, test operation process and test operation requirements of the corresponding equipment, which can improve the assembly efficiency and accuracy of workers.

[0076] In an embodiment of the present application, the system further includes a display for displaying the execution operations of the assembly module, the execution operations of the test module, and the execution operations of the controller.

[0077] Those skilled in the art will appreciate that the embodiments described herein are intended to help readers understand the principles of the present invention, and it should be understood that the scope of protection of the present invention is not limited to such specific descriptions and embodiments. Those skilled in the art can make various other specific variations and combinations based on the technical teachings disclosed in the present invention without departing from the essence of the present invention, and such variations and combinations are still within the scope of protection of the present invention.
