All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0035] In the description of the embodiments of the present invention, "a plurality of" represents at least two.

[0036] Embodiment 1:

[0037] Since the Arinc429 data definitions of flight parameters of different airlines and different aircraft models are different, even for the same airline and the same aircraft model, there are also cases where the same label definitions are different for different channels, and even problems such as inaccurate system interface ICDs obtained, resulting in many problems when the new system is installed on the aircraft, and a large amount of debugging work for trial and error and troubleshooting is required. To solve the above problems, this embodiment provides a general configurable decoding method based on airborne Arinc429 communication, which is used to perform data decoding on Arinc429 data through a target system, as Figure 1 shown, the target system includes a receiving module, a decoding module and a GUI display module. The receiving module and the decoding module reside in the airborne equipment, and the GUI display module resides in the portable debugging equipment.

[0038] When performing data decoding through the target system, it is achieved through the following steps, as Figure 2 shown:

[0039] S1, control the receiving module to continuously obtain the Arinc429 data sent by the peer device through the underlying driver, and send the Arinc429 data obtained by the receiving module to the decoding module.

[0040] Among them, the above Arinc429 data includes 32-bit Arinc429 data, label data, and channel number data, that is, the Arinc429 data includes Arinc429 data (32-bit), the corresponding label (octal number of the lower 8 bits of the Arinc429 data), and the channel number, and all of these are sent to the decoding module.

[0041] S2, use the decoding module to obtain the decoding configuration parameters of the Arinc429 data by reading the preset configuration file, and control the decoding module to perform decoding processing on the Arinc429 data based on the decoding configuration parameters.

[0042] Specifically, the decoding module reads the configuration file at startup to obtain the relevant parameters for decoding. The decoding module pushes all the received data with labels and the decoding values calculated according to the configuration file to the GUI module for display. In addition, the decoding module also updates the configuration parameters received from the GUI display module to the configuration file and uses the new configuration parameters for decoding.

[0043] S3, obtain the decoding result of the decoding process through the GUI display module, and display the decoding result and decoding parameters through the interface list in the GUI display module.

[0044] Among them, the GUI module displays all the label data and decoding values of the decoding module in the interface list. The user selects a label and dynamically modifies the decoding method (BNR, BCD, ISO#5) and related parameters. The GUI module sends the set configuration parameters to the decoding module. The decoding module calculates the decoding result using the newly set configuration parameters and updates it to the GUI display module for display in the interface.

[0045] Optionally, the above method further includes:

[0046] Receive the decoding configuration parameters from the GUI display module through the decoding module and update them to the configuration file, and use the decoding module to perform decoding processing with the new decoding configuration parameters.

[0047] Among them, dynamically modify the decoding method through the label data obtained by the GUI display module, and the decoding configuration parameters corresponding to each decoding method; the above decoding methods include the BNR method, the BCD method, and the ISO#5 method, and at least the BNR decoding configuration, the BCD decoding configuration, and the ISO#5 decoding configuration are defined in the decoding module.

[0048] Specifically, the configuration file template defines three major categories of configuration parameters: BNR decoding configuration, BCD decoding configuration, and ISO#5 decoding configuration. As shown in Table 1, among them: The BNR decoding configuration contains a label data, and it is necessary to specify the starting bit position, ending bit position, sign bit position, and resolution of the data. The BCD decoding configuration contains a label data, and this label data contains multiple BCD units. Each unit needs to specify the starting bit position and ending bit position, and finally, the results are combined by multiple BCD units. The ISO#5 decoding configuration contains multiple label data, and each label contains multiple character units. It is necessary to specify the starting bit position and ending bit position of the character units, and finally, the results are combined by the character units.

[0049] Table 1

[0050] Decoding method Number of labels Decoding parameter BNR One Start bit position, end bit position, symbol bit position, resolution BCD One Multiple BCD units: start bit position, end bit position ISO#5 Multiple Multiple character units: start bit position, end bit position

[0051] Among them, the configuration file is managed according to tags such as time, date, altitude, longitude, latitude, wind speed, wind direction, departure airport, and destination airport. Each tag contains its own decoding configuration, which is consistent with the definition in the configuration file template. At the same time, according to the models that have been successfully debugged, multiple model configuration files are generated. Users can select the configured models in the interface and send them to the decoding module for data decoding.

[0052] Furthermore, after decoding, the decoding module judges the data continuity according to the decoded value according to its tag characteristics. When it is judged that the data change exceeds the allowable change range, it is determined as a jump, a jump warning is generated, and it is marked as a red warning in the interface for users to strengthen the analysis of decoding anomalies.

[0053] Specifically, the above decoding process is as follows: First, the receiving module continuously obtains the Arinc429 data sent by the peer device through the underlying driver, and sends the received Arinc429 data (32bit), the corresponding label (the octal number of the lower 8 bits of the Arinc429 data), and the channel number to the decoding module; Second, when the decoding module starts, it reads the configuration file to obtain the relevant parameters for decoding. The decoding module pushes all the received data with labels and the decoded values calculated according to the configuration file to the GUI module for display. In addition, the decoding module also updates the configuration parameters received from the GUI display module to the configuration file and uses the new configuration parameters for decoding; Finally, the GUI module displays all the label data and decoded values of the decoding module in the interface list; The user selects a label and dynamically modifies the decoding method (BNR, BCD, ISO#5) and related parameters. The GUI module sends the set configuration parameters to the decoding module. The decoding module calculates the decoding result using the newly set configuration parameters and updates it to the GUI display module for display in the interface.

[0054] In this embodiment, the decoding method can dynamically modify and distribute the decoding method and parameters in real time, which are used to calculate the value of Arinc429 data to determine whether it is consistent with the system interface ICD. When they are inconsistent, the system interface ICD and the decoding method can be adjusted in time. At the same time, the Arinc429 data decoding can be completed by selecting the decoding configuration parameters of the completed aircraft model. The jump can also be judged and an alarm can be issued by comparing the change of the 429 decoding value, so as to strengthen the user's decoding anomaly analysis.
