摘要
结合实际需要,提出一种基于CAN总线的传感器节点设计方法。系统MCU采用集成了CAN控制器的dsPIC30F4013。通过12位A/D转换器采集到各种传感器的信号,经由MCU预处理后,再通过CAN总线传输给上位机。该方案在很大程度上减轻了上位机的负担,同时也提高了系统的健壮性。
In light of the requirement to the multi-sensor system,this paper brought up a sensor node design method based on CAN bus.In the system,dsPIC30F4013 integrating CAN controller was used as MCU,the signals from various sensors were converted by a 12 bit A/D converter,and then the data were pretreated by MCU,and transmitted to the host computer through CAN bus.The program could reduce the burden of the host computer,and improve the system robustness.
