A kind of encapsulation method and device of network layer icd

Abstract

The invention provides a network layer ICD packaging method and device. A bus link corresponding to each logic parameter is matched out from pre-built bus links, workloads of personnel in the network layer ICD packaging process can be reduced, and accordingly time consumed for the packaging process is shortened; then whether a first data block exists in the corresponding bus links or not is judged according to calculated required domain length values of the logic parameters, if yes, the corresponding logic parameters are directly stored in blank areas of signals in the first data block so that a source device can use the first data block to send the logic parameters to a target device, and if not, a second data block is newly built to store the corresponding logic parameters. Therefore, based on the relevant information of the bus links, the logic parameters are automatically stored in the corresponding data blocks satisfying the required domain length values of the logic parameters, the workloads for manual packaging participation are further reduced, and the work efficiency of network layer ICD packaging is indirectly improved.

Description

technical field [0001] The invention relates to the field of avionics systems, and more specifically relates to a method and device for encapsulating a network layer ICD. Background technique [0002] As the core part of the system architecture, the Interface Control Document (ICD) gives the definition of the meaning, composition and format of messages sent and received between subsystems in the avionics system. It is a modern complex avionics system architecture design. key part of . Among them, the network layer ICD is to define the network layer message interface of the interface control document (InterfaceControl Document, ICD). By encapsulating it, the logic parameters of the logic layer ICD can be encapsulated into the domain data of the network layer ICD, so as to realize the avionics system communication between different devices. [0003] At present, the method of encapsulating the ICD at the network layer mainly relies on manual completion of all encapsulation st...
