Problems solved by technology
The AADL language provides descriptions of the corresponding components for the software and hardware of the avionics system, but there is no corresponding component for the inter-platform network topology, so AADL has flaws in the description of the multi-platform avionics system
[0014] 2) Limitations of resource binding
[0019] 1) The limitation of the system network topology. The AADL language provides descriptions of the corresponding components for the software and hardware of the avionics system, but there is no corresponding component for the inter-platform network topology.
[0020] 2) The limitations of the data link connection between nodes. At the system level, the topology of the space needs to be considered between the nodes, and the form of the data link should be considered for the connection. The existing AADL design method cannot meet the requirements.

Embodiment Construction
[0031] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0032] The present invention is based on the dynamic model driving method of data link networking of AADL, specifically comprises the following steps:
[0033] 1) Extend the data link component to the AADL language
[0034] The expansion of data link components is divided into two parts: functional expansion and re-description, and injection of non-functional attributes, such as figure 1 shown. In the expansion of functional attributes, the general description of the data link should be defined first, and the functions of the data link should be encapsulated at the bottom layer. The packaged content should be combined with the general description and classification method of the aviation field data link. Definition of components, and matching of communicating end systems. The interface of these two parts should also be redefined. At the ...

The invention belongs to an avionics system design technology, and relates to a data link networking dynamic model driving method based on an AADL. The method comprises the following steps that 1, expanding an AADL language to describe an aviation data chain in a component mode, and establishing an AADL model of a multi-platform avionics system; Step 2, realizing interaction between the AADL modeland external network simulation through transmission of an XML file; And step 3, driving the AADL model to perform dynamic simulation by utilizing an external network simulation result fed back to the AADL model. On the basis of modeling the physical architecture of the electronic system in the traditional AADL language, the physical architecture description of the system is expanded to a multi-platform system organized by a wireless link by expanding a data link communication component.
