| Abstract: | This paper presents a system communication designing method based on Time-Triggered Architecture. In accordance with the communication demand of Integrated Data Management System （IDMS）, we have constructed an IDMS communication simulation system based on Time-Triggered Protocol with rrPDevelopment Cluster. Precise global clock synchronization of TTP provides system precise clock information and synchronization. Fault-tolerant approach provides mission-critical system credible and fault-tolerant communication. The cluster schedule mechanism makes sufficient use of bandwidth to the system. In the end, we analyze bus parameters of the simulation model and summarize the advantages that Time-Triggered Architecture can provide to Avionics environment application. |
