Embodiment Construction

[0037] In the first step, the present invention ensures that the ICD format is consistent with the ICD format of the avionics system, and supports external import of ICD files of the avionics system. In order to ensure the consistency and correctness of the configuration information used by the AFDX network equipment and the ICD file of the avionics system, the present invention needs to pass the ICD block information integrity and parameter range limitation check. The steps are as follows:

[0038] (1) Import ICD, and the ICD format is consistent with the ICD format of the avionics system. ICD information includes:

[0039] Table 1 ICD information list

[0040] serial number ICD information 1 device name 2 device ID 3 Equipment type 3 ICD ID 4 source partition name 5 destination partition name 6 message length 7 refresh cycle

[0041] (2) Verify the integrity of the ICD block information to check, if there is ...

Abstract

The invention belongs to computer communication technologies, and relates to a method for converting an interface control file to an AFDX communication network equipment configuration file. Accordingto the method, the attributes of communication messages in an AFDX communication network are acquired through analyzing the interface control file of an avionic network system, the communication messages are combined and a VL is generated, and at last a terminal system and a switch configuration file are generated. According to the method, the consistency between the network equipment configuration file and an ICD file is ensured, the manual error probability is reduced, and the correctness of generation of the configuration file is improved, the building workload of the configuration information is greatly reduced, and the network system design and comprehensive efficiencies are greatly enhanced.

Description

technical field [0001] The invention belongs to computer communication technology, and relates to a conversion method from an interface control file to an AFDX communication network equipment configuration file. Background technique [0002] The Interface Control Document (ICD) is a key part of the modern complex avionics system architecture. As the core part of the avionics system, the ICD provides the meaning, composition and format of the messages sent and received between the subsystems of the avionics system, etc. The definition of content is an important basis for avionics system communication. [0003] Avionics Full-duplex Switched Ethernet (AFDX) is developed on the basis of civil Ethernet. It is a switch-centered star network. The reliability, low latency, and delay determinism of network communication. The AFDX end system configuration file includes message configuration and VL configuration, and the switch configuration file includes VL forwarding configuration....
