Problems solved by technology

[0006] Unstable file transfer: The TFTP protocol used for file transfer has no fault tolerance, and the transfer is prone to failure in an unstable network environment;
[0007] Backward software architecture: files can only be transferred sequentially, and multi-threaded parallel transfer is not supported

Embodiment 1

[0089] A data loading method for an airborne avionics device, which transmits a target file, includes the following steps:

[0090] S100. Query online and add a target device that needs to perform file transfer;

[0091] S200. Initiate a transfer request to the target device, and after receiving information that the target device agrees to transfer the target file, perform multi-threading between the target device and the loader for at least one target file that needs to be transferred ground transmission.

[0092] In this example, if figure 1 As shown in , it is a flow chart of online query of the target device, and the specific steps include:

[0093] In step S100, the specific steps of inquiring about the target device online include:

[0094] S110, scan and obtain all network cards on the loader;

[0095] Generally, multiple network cards are installed on the computer, but there is only one target device for transferring files. In order to save the need to manually obs...

Embodiment 2

[0152] The invention also discloses a data loading system for airborne avionics equipment, which includes a file transfer module for transferring target files, and also includes:

[0153] Query module: used for online query and adding target devices for file transfer;

[0154] Multi-threaded transmission module: used for multi-threaded transmission of the target files that need to be transmitted. All process files are generated on demand during the transmission process. The generated files are stored in the temporary folder of the system and are automatically deleted after a transmission operation is completed. Reduce unnecessary operations by users. The format of the process file is stipulated in the ARINC615A-3-2007 and ARINC665-3-2005 standards, and will not be repeated here.

[0155] The software interface of the airborne avionics equipment data loading system is as follows: Image 6 As shown, the software interface design of the airborne avionics equipment data loading ...

Embodiment 3

[0159] The invention also discloses an electronic device, the electronic device includes: a memory and a processor; the processor is used to read the program in the memory and execute the steps of the method for loading the data of the airborne avionics device .

Abstract

The invention relates to the technical field of airborne avionics equipment, and discloses an airborne avionics equipment data loading method, which is used for transmitting a target file and comprises the following steps: S100, inquiring and adding a target device needing file transmission on line; and S200, a transmission request is initiated to the target device, and after information that the target device agrees to transmit the target file is received, the target file needing to be transmitted is transmitted between the target device and a loader in a multi-thread mode. The invention further discloses an airborne avionics equipment data loading system, electronic equipment and a storage medium. According to the method, the Rev1.0 and the Rev2.0 are compatible in the TFTP protocol, an automatic error correction function of file transmission is designed on the basis of a protocol standard, and the reliability of file transmission is further improved.

Description

technical field [0001] The invention relates to the technical field of airborne avionics equipment, in particular to a data loading method, system and electronic equipment for airborne avionics equipment. Background technique [0002] With the start and development of domestically produced large aircraft, domestically produced airborne avionics equipment has also emerged as the times require. Different from the mature avionics industry in foreign countries, as an emerging industry, localized airborne avionics equipment will inevitably face frequent data import and export requirements during the design, production and commissioning process, such as debugging and modification due to faults at any time Upgrade software, modify configuration files, view operation logs, etc. [0003] All airborne avionics devices that use Ethernet as data import and export interfaces must comply with the requirements of standard documents ARINC615A-3-2007 (Software Data Loader Using Ethernet Int...
