Problems solved by technology

[0002] The existing mainstream aviation on-board bus network adopts the event-based communication mechanism, the end system of the network can access the communication at any time, and the message can be sent as soon as there is a message, which inevitably causes transmission competition and brings difficulties to the end-to-end data stream transmission. Controlled delay and jitter cannot meet the needs of new avionics systems for distributed communication applications that are time-critical and safety-related

Abstract

The invention discloses an SOC-based communication gateway controller, which includes a wired device time-triggered scheduling module, a wired device protocol processing module, and a wireless communication scheduling module designed on the FPGA circuit of the SOC chip to realize a wireless communication network system and adopt " "Wired time-triggered switching network" systems communicate with each other. The invention can realize the deterministic non-competitive transmission of the TT data stream on the communication data between the two networks in the cross-network, and can greatly improve the certainty and real-time performance of the cross-network data communication; at the same time, its powerful fault detection and fault tolerance isolation, The reliability and security of network communication are greatly improved, so that the airborne bus architecture using layered dual-network coordination can be better qualified for real-time requirements and security applications.

Description

technical field [0001] The invention belongs to the technical field of airborne bus communication in avionics systems, and in particular relates to an SOC-based communication network that realizes high real-time and high deterministic communication of "wired time-triggered switching network" and wireless communication network nodes under a time-triggered communication architecture. Communication Gateway Controller. Background technique [0002] In the existing mainstream aviation airborne bus network, due to the event-triggered communication mechanism, the end system of the network can access communication at any time, and messages can be sent, which inevitably causes transmission competition and brings inconvenience to end-to-end data stream transmission. The delay and jitter of the control cannot meet the needs of new avionics systems for distributed communication applications related to different time criticality and safety. Time-triggered Ethernet (“wired time-triggered...
