Problems solved by technology

But it does not support the expansion of the data source (server). The one-to-many relationship between the server and the client limits the flexibility of the same client to obtain aircraft parameters from different sources.

Embodiment Construction

[0045] In the civil airliner information system, the method is adopted to realize the dynamic expansion of the server and the receiver between the airborne information system and the avionics network, and the subscription and release of aircraft parameters.

[0046] In order to realize data communication between various airborne network protocols in the airborne equipment, the present invention defines such a communication method and system: based on the "provide subscription-based services" and "use XML for transmission" in the ADBP protocol method, combined with the subscription publishing (Pub-Sub) mechanism, to achieve the scalability of the server and the client from 1:1 to N:M, by using the intermediate node (Proxy) for data distribution, using the server (Server), The communication model of intermediate nodes and clients (Client).

[0047] System composition

[0048] The basic system architecture adopted in this method consists of figure 1 As shown, it includes the co...

Abstract

The invention belongs to the technical field of airborne embedded software, and particularly relates to a dynamically extensible airborne network service data communication method. Data communicationbetween multiple servers and the multiple clients based on different airborne network protocols can be realized, and dynamic extensible data subscription and publishing problems between different network domains and different network protocols in an airborne environment are effectively solved. The method comprises the following steps of (1) establishing a communication system, wherein the communication system comprises a server and a client, and further comprises an intermediate node arranged between the server and the client; (2) carrying out a data publishing process from the server to the intermediate node; and (3) carrying out a data subscription process from the client to the intermediate node.

Description

technical field [0001] The invention belongs to the technical field of airborne embedded software, and in particular relates to a dynamically expandable airborne network service data communication method. Background technique [0002] AEEC released the ARINC 834-3 standard in 2012, which provides a set of protocols including GAPS (Generic Aircraft Parameter Service), STAP (Simple Text Avionics Protocol) and ADBP (Avionics DataBroadcast Protocol), where ADBP defines a subscription-based Service, which transmits and receives aircraft parameters as XML objects between the data source (server) and the client, so that applications running in the airborne system can access specific avionics network data. [0003] For the interior of the airborne system, the ARINC834-3 standard can be used to obtain the aircraft parameters, the data source application is used as the server, and the avionics application is used as the client, that is, the aircraft parameters inside the airborne syst...
