【摘要】 随着CAN总线技术的发展,气动领域对CAN总线的需求也不断扩大,将CAN总线引入气动系统,实现气动系统数据采集和控制的总线化,促进气动技术的进步。设计带CAN总线的I/O、A/D、D/A智能节点,将气动系统中的数据采集设备、控制设备、中央控制器与CAN智能节点有机结合起来,通过CAN协议进行通信,实现了气动系统中央控制器与数据采集设备以及控制设备间的总线连接,并以此构成一个气动位置控制系统,试验结果证明该系统完全满足设计要求。更多还原

【Abstract】 Fieldbus CAN (Controller Area Network) is introduced into the pneumatic system, and the data acquiring and controlling of pneumatic system based on Fieldbus are realized. The intelligent node based on CAN fieldbus, such as I/O, A/D, D/A and so on, had been developed. The data acquiring apparatus, controlling apparatus and central controller of pneumatic system are combined with CAN intelligent node that communicate by CAN protocol, and the central controller, data acquiring apparatus and controlling apparatus of the pneumatic system connecting with Fieldbus are realized, the result showed that the pneumatic system worked very well.更多还原
