Embodiment Construction

[0075] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0076] After research, the inventor found that when designing the top-level of the avionics network system, only the publisher and receiver of the information are often considered. For example, the altitude sensor node will send altitude information to the network, and the flight control calculation node receives this information and performs a series of processing. , but does not consider how the altitude sensor node is physically connected to the flight contr...

Abstract

The invention discloses a communication method and a communication system for an avionics network system. The communication method comprises the following steps: recording configuration information of each node in the avionics network system in a blueprint configuration table, and initializing the current node based on a DDS standard program when the avionics network system performs communication; acquiring data needed during information interaction from the blueprint configuration table when each node performs information interaction through an FC-AE-ASM bus. According to the method and system disclosed by the invention, the FC-AE-ASM protocol is matched with the DDS standard, so that the network protocol is abstracted and subjected to black-box measurement during the network design; on one hand, the node attribute configuration of each node is accelerated, and the workload of network planning services is reduced; on the other hand, a designer does not need to consider the physical connection between a data calculation unit and a sensor and the physical attributes of the physical connection on the buses and needs to focus on message communication of each communication node, so that the design cycle of the avionics network system is shortened.

Description

technical field [0001] The present invention relates to the technical field of data communication, and more specifically, to a communication method and system of an avionics network system. Background technique [0002] In the field of military aviation, in order to meet the requirements of avionics equipment for dynamic changes in messages and message transmission rates, avionics network systems have gradually adopted FC-AE-ASM (Fibre Channel-Avionics Environment-Anonymous Subscriber Message Fiber Channel Avionics Environment Anonymous Subscriber Message ) bus as a message transmission bus. Avionics network system designers need to complete two tasks when configuring the avionics network system: the first is the network communication service, which is the core business of the entire avionics network and belongs to the top-level design content, and is used to realize message attribute configuration; The second is the network planning service, which belongs to the bottom lay...
