| 摘 要： | 在自主研发的CAN总线实时仿真系统上,通过软件编程,分别实现了CAN协议通讯和TTCAN(Time-Triggered CAN)协议时间触发通讯.通过对两种不同通讯协议下的网络实时性进行比较,分析了TTCAN通讯网络的实时性.研究结果表明,引入TTCAN协议的时间触发功能能解决CAN协议中的总线冲突问题,有效提高了实时性要求较高的周期型消息的实时性. |

| Abstract: | The communication based on the protocol of CAN(Controller Area Network)and TTCAN(Time-Triggered CAN)was implemented by programming on the real-time simulation system for the CAN bus,and the real-time performance of the communication was analyzed.The results indicate that the bus conflict in the event-triggered CAN network can be resolved and the real-time performance of the periodic message can be improved by adopting the time-triggered function of TTCAN protocol. |
| Keywords: | TFCAN protocol time-triggered bus conflict real-time performance |
