多路CAN总线转换卡的设计

Design of multi-channel converting cards based on the CAN bus

针对在工厂监控系统中,CAN总线的监测节点数目受限制的问题,采用了高速低阻抗电子开关MAX4684,设计了多路CAN总线转换卡的硬件电路和软件编程.实验结果表明,所设计的多路CAN总线转换卡简单实用,可靠性高,成功地解决了工厂监测系统中的实际问题.

The multi-channel converting cards based on CAN bus is designed by using the high speed and low resistance electronic switches MAX4684 due to the limitation of port numbers of monitoring system in the factories. The results demonstrate that the multi-channel converting cards are feasible and successfully solve the monitoring system problem in the factories.
