Abstract

The invention provides a data transmission method and a data transmission device, and is used for solving the problem of low efficiency of data transmission between devices which respectively use ARINC (Aeronautical Radio, Incorporated) 429 Protocol and AFDX (AFDX Avionics Full-Duplex Switched Ethernet) Protocol in the prior art. The method comprises the following steps: receiving data frame(s) in a first format; adding net load data and a transmission destination identification thereof in the data frame(s) in the first format into data frame(s) in a second format; and transmitting the data frame(s) in the second format. The technical scheme provided by the invention is beneficial to solving the problem of low efficiency of data transmission between devices which respectively use ARINC 429 Protocol and AFDX Protocol, thereby implementing efficient conversion of aviation electronic data, enhancing the system performance and increasing the utilization ratio of the bandwidth.

Description

technical field [0001] The invention relates to a data transmission method and a data transmission device. Background technique [0002] The avionics device plays a key comprehensive role in the modern aircraft, and is very important to improve the performance of the aircraft in all aspects. The avionics device takes the comprehensive display and control device as the core, and integrates a large number of airborne equipment such as mission computer, air data device, inertial navigation device, plug-in management device, radio communication device, identification friend or foe device, etc. However, the traditional MIL-1553B or ARINC429 bus technology has defects such as slow data exchange speed and complicated cables. [0003] In the new generation of avionics devices, a large number of airborne information devices such as mission computers, radar devices, navigation devices, and radio communications will use a new high-speed, high-bandwidth bus such as AFDX as the backbone...
