摘要
论文以TJA1040作为CAN收发器连接物理总线与CAN控制器,搭建总线型结构试验通信平台,实现CAN信号差动发送与接收,研究终端电阻对信号幅值的影响,给出远距离通信条件下终端电阻配置建议;搭建星型拓扑结构试验平台,探究星型结构终端电阻最佳配置方案,根据不同情况配置不同终端电阻,有利于提高CAN通信效果。
In this paper,TJA1040 is used as CAN transceiver to connect physical bus and CAN controller,build bus-type structure communication platform,realize CAN signal differential transmission and reception,study the influence of terminal resistance on signal amplitude,and give terminal resistance configuration suggestion under long-distance communication conditions.A star topology platform is built,and the optimal configuration scheme of the star structure terminal resistance is explored.Different terminal resistances are configured according to different situations,which is beneficial to improve CAN communication effect.
