In order to facilitate a clearer understanding of various embodiments of the present invention, some relevant background knowledge is first presented as follows.
The ARINC429 bus is widely applied to civil aviation aircraft by virtue of the characteristics of high reliability, stable performance, strong anti-interference performance and the like, and the ARINC429 bus protocol prescribes digital information transmission requirements between avionics system equipment and related systems or equipment. The on-board ICD, as a core part of the architecture of the avionics system, is a technical document for defining and recording functions, transmission characteristics and usage instructions of the data between systems or devices. The aviation simulator relies on an onboard ICD as design input in the development process, and the construction of a system model is completed based on the design input.
In the development process of the existing aviation simulator subsystem simulation model, manual screening and identification of ARINC429 bus signals are generally carried out according to an onboard ICD in a complete machine state, ARINC429 bus data packets required by specific subsystem simulation equipment are positioned, and then the 32-bit ARINC429 bus data packets are manually analyzed to determine the data meaning of each bit transmission in the data packets.
However, in the airborne ICD with huge data information, based on the traditional manual screening method, the ARINC429 bus signals which are specifically transmitted and are positioned to a certain bus in the ARINC429 buses with huge data information are huge in workload, and in the development process of the simulation model of the aircraft simulator subsystem, the ARINC429 bus signals required by the simulation system need to be screened continuously and repeatedly in the airborne ICD, so that the development efficiency of the simulation model is definitely affected by the manual screening method, and screening errors easily occur in the manual screening method, so that the screening accuracy is difficult to ensure. And with the continuous upgrading and updating of some development type aviation equipment, the airborne ICDs are synchronously updated, after each updating, the aviation simulator subsystem simulation model developer repeatedly performs screening work of ARINC429 bus data signals according to the new version of airborne ICDs according to new design requirements, and the workload of the developer is further increased.
