Design of Time Triggered Ethernet System Based on ZYNQ
Time triggered Ethernet(TTE)is a real-time network communication technology based on standard Ethernet.It uses"clock synchronization"and"time triggering"to ensure the real-time and deterministic communication of key data.The"triggered"communi-cation method cannot guarantee the determinism of communication.The reliability of the network is improved through redundant trans-mission,fault detection and isolation mechanisms.It has the technical characteristics of large bandwidth,being strong real-time,high re-liability and compatibility with standard Ethernet.To meet the strong real-time communication requirements of safety-critical systems,ZYNQ chips are used to implement the TTE network protocol,and functions such as data acquisition,data transmission,and data inter-pretation are completed.The test shows the high reliability and timeliness of TTE technology,and shows the compatibility of the system and the application expansion of multi-task conditions.
