Problems solved by technology

[0004] AFDX cannot communicate directly with standard Ethernet
[0005] 2. Laboratory development in the AFDX network has high hardware costs (expensive AFDX switches and a large number of boards)
At present, there is no technology on the market that can directly communicate between the AFDX network and standard Ethernet, and can only indirectly communicate with each other with the help of hardware devices and other technologies

Embodiment Construction

[0013] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0014] Such as figure 1 As shown, in the AFDX network, if the terminal system ES1 needs to communicate with ES2, ES3, and ES4, an AFDX switch is required between them, which is expensive, and a board card needs to be installed on each terminal system. This embodiment adopts ES1 communicates with three terminals ES2, ES3, and ES4. If there are more terminals, more boards are needed.

[0015] Adopt technical scheme of the present invention, comprise:

[0016] (1) AFDX data to standard Ethernet

[0017] Because of the frame differences between AFDX and standard Ethernet, different parameters need to be configured for the two. The two can communicate by defining configuration files. As defined in afdx_to_eth.json:

[0018]

[0019] (2) Standard Ethernet data to AFDX

[0020] Standard Ethernet listens on a local port, and when data is received fro...

Abstract

The invention provides an ARINC 664 aviation Ethernet and standard Ethernet data conversion method, which comprises the following two steps of: forwarding from an avionics full duplex switched Ethernet to a standard Ethernet, and forwarding from the standard Ethernet to the avionics full duplex switched Ethernet. According to the ARINC 664 aviation Ethernet and standard Ethernet data conversion method, direct communication between AFDX data and data in the standard Ethernet is achieved, and compared with an existing technical scheme, the method simplifies the development process, reduces the requirement for hardware and reduces cost.

Description

technical field [0001] The invention belongs to the technical field of Ethernet, and in particular relates to an ARINC 664 aviation Ethernet and standard Ethernet data conversion method. Background technique [0002] Avionics FULL Duplex Switched Ethernet (Avionics FULL Duplex Switched Ethernet, referred to as: AFDX) is a deterministic communication system suitable for avionics systems that has been supplemented, modified and limited on the basis of industrial standard Ethernet. Network, AFDX technology is used for data exchange between aviation subsystems. At present, this system has been successfully applied to Airbus A380 aircraft, Boeing B787 aircraft and China C919 single-aisle aircraft. AFDX can provide the robustness and guaranteed bandwidth and quality of service required by the avionics system, and can be applied to the new generation of aviation buses that require high real-time performance, high reliability and large bandwidth. The use of AFDX technology can gre...
