摘要
针对传统CAN总线通信系统基于仲裁发送机制所存在的通信通道易堵塞、实时性、可靠性差问题,设计了CAN总线节点轮询通信系统。系统CAN总线通信机制为采用主从控制下的节点轮询方式。最后,通过实验完成了CAN轮询通信测试,结果表明,CAN通信实时性高,整机运行稳定、可靠。
Aiming at the problems of communication channel blockage,poor real-time and low reliability for traditional communication system of CAN bus based on arbitration transmission mechanism,a CAN bus node-polling communication system is designed.The communication mechanism of the system adopts node-polling of CAN bus under master-slave control. Finally,the CAN polling communication test is completed through the experiment. The results show that the CAN communication has a high real-time performance and the whole machine runs stably and reliably.
