[0037] As the low-altitude economy is developing rapidly in the field of aircraft, the requirements for aircraft safety, functionality, and production cycle are becoming increasingly higher. In related technologies, the aircraft production process cannot meet the requirements of mass production because it requires manual offline testing. Therefore, it is very necessary to improve productivity in the key links of aircraft production, such as reducing manual participation in offline testing and offline configuration, so that the process of aircraft offline testing and configuration can not only meet safety requirements, but also cope with the differences brought by multifunctionality, and improve the production cycle.

[0038] In response to the above problems, an embodiment of the present application provides a method for offline detection of an aircraft, which can automatically perform offline detection on an aircraft to be detected offline, thereby reducing or avoiding human participation in the offline detection process of the aircraft, which is conducive to improving the efficiency and accuracy of offline detection of aircraft.

[0039] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0040] Figure 1 It is a flow chart of an offline detection method for an aircraft shown in an embodiment of the present application.

[0041] See also Figure 1 , a method for off-line detection of an aircraft, the method being applied to an electrical inspection service device, the method comprising:

[0042] Step 101: in response to receiving an offline detection request, obtaining a preset identifier according to the offline detection request.

[0043] In some embodiments, when there is a need for offline inspection of an aircraft, an offline inspection request may be initiated. For example, the offline inspection request may be initiated by a terminal, and the request carries a preset identifier for characterizing the terminal, so that the electrical inspection service device obtains the preset identifier after receiving the request.

[0044] Step 102: According to the preset identifier, obtain aircraft information matching the preset identifier.

[0045] In some embodiments, the electrical inspection service device may include a storage device for storing aircraft information that matches a preset identifier; the aircraft information that matches the preset identifier may also be stored in the cloud, and the electrical inspection service device obtains the aircraft information that matches the preset identifier by calling a cloud server.

[0046] In some embodiments, the aircraft information may include the preset identification, a model code representing the aircraft model, a material code, and an aircraft unique code, etc.

[0047] Step 103: Obtain a resource file for offline testing according to the aircraft information.

[0048] In some embodiments, resource files for offline detection applicable to different types of aircraft may be configured in advance, and the execution of the resource files may enable automatic offline detection of the aircraft to be detected.

[0049] In some embodiments, the resource files may include diagnostic resources, whole machine configuration resources, workstation resources, and other resource files that may be used for offline testing.

[0050] Step 104 , sending a resource file to the terminal so that the terminal performs offline detection on the aircraft to be detected offline according to the resource file.

[0051] In some embodiments, for example, a resource file that can be used for offline detection is sent to the terminal, and the terminal initiates offline detection of the aircraft to be detected based on the resource file.

[0052] The offline detection method for aircraft in the embodiment of the present application can obtain a preset identifier after receiving an offline detection request, thereby obtaining aircraft information matching the preset identifier through association matching according to the preset identifier, and retrieving the entire aircraft information; then using the matched aircraft information, obtaining a resource file for offline detection; sending the resource file that can be used for offline detection to the terminal, and the terminal initiates offline detection of the aircraft to be detected offline according to the resource file, so that the offline detection process of the aircraft reduces or avoids manual participation, which is conducive to improving the efficiency and accuracy of offline detection of aircraft. It can also realize batch automatic process for offline detection, which is conducive to standardization, process and automation of aircraft offline detection, and meet the productivity of batch production lines.

[0053] In some embodiments, the aircraft information includes: a model code characterizing the aircraft model; obtaining a resource file for offline detection based on the aircraft information includes: determining diagnostic resources suitable for the aircraft model based on the model code.

[0054] It can be understood that corresponding model codes can be configured for different types of aircraft models, so as to add offline inspection and configuration processes and strategies for different models, thereby developing resource files that match the process strategies and other requirements.

[0055] It can be understood that diagnostic resources suitable for the aircraft model, such as diagnostic components, diagnostic scripts, and diagnostic menus for different aircraft models, can be screened according to the aircraft model code.

[0056] The offline detection method for aircraft in the embodiment of the present application can determine the diagnostic resources suitable for the aircraft model based on the model code, and can adapt to different aircraft models and different offline detection configuration processes and strategies by adjusting the diagnostic resources.

[0057] In some embodiments, the aircraft information includes: a material code, which is used to generate a characteristic code that characterizes the entire aircraft; based on the aircraft information, a resource file for offline testing is obtained, including: based on the characteristic code, obtaining the entire machine configuration resources that are adapted to the aircraft.

[0058] It can be understood that the material code refers to the characteristic code used to generate the characterization of the aircraft, such as the aircraft material number. The material code is used to distinguish the aircraft material configuration of the aircraft model. For example, the characteristic code of the aircraft can be composed of the material code and the version number of the aircraft configuration list; then the aircraft configuration resources can be obtained through the characteristic code of the aircraft.

[0059] In some embodiments, the whole machine configuration resource may include association information of multiple electronic control units. Sending a resource file to a terminal so that the terminal performs offline detection on the aircraft to be detected offline according to the resource file includes: sending the whole machine configuration resource to the terminal so that the terminal performs offline detection on multiple electronic control units according to the whole machine configuration resource.

[0060] For example, the electrical inspection service equipment obtains the whole machine configuration list through the characteristic code of the whole aircraft, which includes the composition information of the whole machine's electronic control unit, software version number, diagnostic routes of each electronic control unit of the aircraft, actual configuration words and other information.

[0061] It is understandable that with the development of science and technology, more and more ECUs are integrated in aircraft. In this case, the detection of the quality of the whole machine's electronic appliances is becoming more and more complex and important. The offline detection method for aircraft in the embodiment of the present application can enable the terminal to automatically perform offline detection on a variety of electronic control units according to the whole machine configuration resources by sending the whole machine configuration resources to the terminal, which is conducive to coping with the more advanced and complex environment of the equipment and electronic components in the current aircraft, without the need for training and learning related offline detection knowledge.

[0062] In some embodiments, the method further includes: sending work station information of the aircraft to the terminal, where the work station information is used to instruct the terminal to perform an offline inspection of the aircraft that is adapted to the work station information.

[0063] The workstation determines the production process of offline inspection and configuration, and different workstations have different processes. Therefore, for different aircraft, the workstation information is sent to instruct the aircraft to perform offline inspection adapted to the workstation information; for example, the diagnostic menu bound to the workstation is automatically executed according to the process arrangement, and the diagnostic menu is associated with the diagnostic component and the diagnostic script, so the function of automatically executing the offline inspection process can be achieved.

[0064] In some embodiments, the method further includes: before sending the resource file to the terminal, upgrading the communication connection protocol.

[0065] The communication connection protocol refers to the communication protocol between the electric inspection service equipment and the terminal. The communication protocol can be a websocket protocol (WebSocket is a protocol for full-duplex communication on a single TCP connection), or a transmission control protocol (TCP, TransmissionControl Protocol) or a remote procedure call protocol (CRPC, CognitiveRadio Protocol Cracking) and other protocols.

[0066] The electrical inspection service equipment upgrades the communication connection protocol to websocket protocol, TCP or CRPC protocol, which can facilitate the subsequent initiation of electrical inspection service message push. The electrical inspection service equipment can remotely send data to the target terminal.

[0067] Figure 2 It is another flow chart of the offline detection method for an aircraft shown in an embodiment of the present application.

[0068] See also Figure 2 , a method for detecting an aircraft offline, the method being applied to a terminal, the method comprising:

[0069] Step 201, sending an offline detection request; wherein the offline detection request carries a preset identifier, and the preset identifier is used to obtain a resource file for offline detection.

[0070] For example, an offline inspection request is sent to the electrical inspection service equipment.

[0071] Step 202: receiving a resource file, and performing offline inspection on the aircraft to be inspected according to the resource file.

[0072] For example, a resource file returned by the electrical inspection service device according to an offline inspection request is received, and an offline inspection is performed on the aircraft to be inspected according to the resource file.

[0073] In some embodiments, the terminal may be integrated into a central control domain of the aircraft; it may also be integrated into other control domains with a network and a communication bus.

[0074] In some embodiments, for example, after the aircraft is powered on, the terminal in the central control domain of the aircraft automatically enters the factory mode, and after entering the factory mode, it automatically initiates a connection to the electrical inspection service device, sends an offline inspection request, and waits for the resource file returned by the electrical inspection service device. The offline inspection request carries a preset identifier, such as the terminal hardware ID (CDCUID).

[0075] In some embodiments, the terminal can perform offline inspection on the aircraft to be inspected according to the received resource file. For example, the terminal automatically executes the diagnostic components and diagnostic scripts of the current workstation according to the diagnostic resources and the workstation resources where the aircraft to be inspected is located. For example, during the execution process, the diagnostic script is matched with the bill of materials, and a diagnostic instruction is sent to each electronic control unit (Electric Control Unit, ECU), such as ecu_1, ecu_2, ..., ecu_n; so that after the ECU receives the instruction, it performs offline inspection on the aircraft to be inspected.

[0076] In some embodiments, the terminal may also receive feedback instruction results. The terminal collects the diagnostic instruction results of each ECU, can calculate the operation result of the current diagnostic component, and report the execution result of the diagnostic component to the electric inspection service device.

[0077] In some embodiments, the terminal includes at least one of the following: a communication module, the communication module is used to connect to the electrical inspection service equipment for communication; a storage module, the storage module is used to store resource files; a display module, the display module is used to display the execution menu matching the offline detection; an input module, the input module is used to interact with the terminal; a function parsing module, the function parsing module is used to provide a script execution environment to run resource files, and / or, the function parsing module is used to provide atomic functions related to diagnostic resources; and an instruction module, the instruction module is used to transmit diagnostic instructions.

[0078] Figure 3 It is a schematic diagram of the structure of the terminal shown in the embodiment of the present application.

[0079] See also Figure 3 The terminal 300 includes a communication module 310 , a storage module 320 , a display module 330 , an input module 340 , a function parsing module 350 and an instruction module 360 ​​.

[0080] In some embodiments, the terminal 300 can connect to the electrical inspection service equipment through the communication module 310 for communication. For example, after upgrading the communication protocol, the electrical inspection service equipment can maintain its ability to remotely push information. The communication module 310 enables the electrical inspection service equipment to remotely send data to the terminal 300.

[0081] In some embodiments, the terminal 300 receives the resource file sent by the electrical inspection service device and stores it locally through the storage module 320, which can reduce a large amount of remote data communication and further speed up the execution speed of offline inspection.

[0082] In some embodiments, after receiving the resource file, the terminal 300 parses and classifies it to obtain diagnostic resources, such as diagnostic menus, diagnostic components, and diagnostic scripts, and displays the diagnostic resources on the user display screen through the display module 330 so that the user can view the execution menu of the offline detection through the display screen.

[0083] In some embodiments, when the user views the offline detection process and results according to the information displayed by the display module 330, the user can interact with the terminal 300 through the input module 340. For example, after the signal from the input module 340 is received by the terminal 300, it is interpreted as a menu execution action. The input module 340 provides an interactive function of the terminal 300.

[0084] In some embodiments, since the diagnostic script is composed of a group of functions, for example, they are combined together through logical judgment of a certain language, and can be written according to the production process. Therefore, in the terminal 300, the diagnostic script is executed to achieve the goal of offline detection, such as key learning, detection of software and hardware version numbers of each ECU, and ECU data calibration. By providing a function parsing module 350 in the terminal 300. Among them, the function parsing module 350 provides a script execution environment, such as being able to run lua scripts. The function parsing module 350 can also be used to provide atomic functions related to diagnostic resources, such as setting FIN codes (aircraft unique code), printing output information, creating UI display windows, obtaining system information, and implementing UDS protocols; wherein, the UDS protocol includes atomic function capabilities such as fault code reading and clearing fault codes.

[0085] Through the atomic function capability provided by the function analysis module 350, production line users can customize different end-of-line inspection processes according to the process requirements of end-of-line inspection and configuration, and solve the problem of adapting different machine models and different workstation processes.

[0086] In some embodiments, the execution of the diagnostic script and function in the terminal 300 will be parsed into a number of diagnostic instructions, and the diagnostic instructions will be sent to the communication bus through the instruction control module 360. Each ECU in the aircraft communicates with the terminal 300 through the communication bus. It can be understood that the communication bus may include a CAN bus and Ethernet, etc.; it can be sent to each ECU in the aircraft through protocols such as DoCAN and DoIP.

For example, the production execution system 710 pushes the aircraft information list to the electrical inspection service device 720 via the https protocol; the aircraft information list may include the aircraft FIN code, the whole machine material list, and the hardware ID information of the terminal 730.

[0110] After receiving the aircraft information, the electrical inspection service device 720 stores the aircraft information list in a storage device such as a database for subsequent matching query.
