摘要
根据时间触发以太网(Time-Triggered Ethernet,TTE)兼容时间触发(Time-Triggered,TT)和事件触发(Event-Triggered,ET)的特性,在时钟同步的基础上,采用离线生成方法生成了时间触发数据的发送调度时刻表,在保证了TT数据实时、可靠发送的同时,给ET类数据的发送留出了足够的带宽。根据TT数据的传输特性,设计了TT数据的发送调度模块,并进行了仿真验证,仿真结果表明TT数据能够在预定时刻点实时稳定地发送。
In accordance of the characteristics of Time-Triggered（TT）and Event-Triggered（ET）of Time-Triggered Ethernet（TTE）,this paper presented a method to create the scheduling timetable of data transferring by the mean of off-line generation,based on clock synchronization.The proposed method ensures the reliability and instantaneity of TT data,while provides enough bandwidth for ET data.According to the transmission characteristics,the sending-scheduling module of TT data has been designed and simulated in the paper.The simulated result shows that TT data is able to be sent stably and real-timely on the scheduled time.
