CAN总线位速率参数在实际应用中设置的研究分析

Analysis on the Baud Rate Parameter Setting of the CAN Bus in Practical Application

CAN总线是一种有效支持分布式控制和实时控制的、多主的异步串行通信网络。CAN通信中的波特率、位周期内取样点数和位置的设置极大地影响了CAN性能的发挥。优化位定时参数,能够保证信息同步,并且对它设置的恰当与否关系着整个系统通信的成败。本文就是针对这点来说明位定时参数的确定方法及其重要性。

CAN bus is a kind of network of the asynchronous serial communication that can effectively support the distributed control and the Real time and the multi-master control. The capability of the CAN bus is influenced greatly by the setting of the baud rate, the number of the sample point and sample place in a bit period. The synchronization of the information is guaranteed by optimizing the parameter of the bit rate. And it can determine the success and failure of the communication. So the method of setting of the bit rate and the importance of the bit rate is stated in this paper.
