Embodiment Construction

[0022] refer to figure 1 , is a structural block diagram of an aviation airborne communication system adopted in the prior art. The aviation airborne communication system adopted in the prior art includes a central communication device, a first non-central communication device to a K-th non-central communication device, K is a natural number greater than 1. The central communication device is electrically connected to each non-central communication device through the RS485 bus. The prior art has the following disadvantages: 1) When the central communication equipment in the communication system fails, the entire communication system will not work, and the reliability is low. 2) In the communication system, if some non-central communication devices are to communicate with each other, the central communication device must be turned on; otherwise, the non-central communication devices cannot communicate with each other. Equipment composition and configuration flexibility is poo...

Abstract

The invention belongs to the technical field of aviation onboard communication, and particularly relates to an acentric communication method suitable for an aviation onboard communication system. The acentric communication method comprises the steps that an annular buffer zone is established inside each aviation onboard communication device, wherein the annular buffer zone comprises n data storage units sequentially arranged in a clockwise direction or an anticlockwise direction, the first data storage unit and the nth data storage unit are adjacent, and the annular buffer zone of each aviation onboard communication device is provided with a storage pointer; when at least one aviation onboard communication device needs to transmit a data package, acorresponding aviation onboard communication device transmits the data package to an Ethernet switch periodically; when at least one aviation onboard communication device receives the data package from the Ethernet switch, the received data package is stored into the data storage unit, in which the storage pointer is placed, then the storage pointer moves clockwise or anticlockwise to anext data storage unit.

Description

technical field [0001] The invention belongs to the technical field of aviation airborne communication, and in particular relates to a centerless communication method suitable for the aviation airborne communication system, which is suitable for the aviation airborne communication system. Background technique [0002] At the beginning of this century, digital circuits began to be widely used, and the communication bus of the aviation airborne communication system gradually developed from an analog bus to a digital bus. The digital bus is represented by the RS485 bus, which is a half-duplex communication method. The aviation airborne communication system is composed of multiple member terminals. In the half-duplex communication mode, only time-sharing transmission is possible, and a central communication device is required to issue a synchronization command to control the time synchronization of each member terminal. [0003] In 2009, the first aviation airborne communicatio...
