【摘要】 设计了基于DeviceNet现场总线的智能执行器,具体介绍了执行器的控制器、驱动器及De鄄viceNet接口。在PC机上插入一块控制局域网(CAN)适配卡并与OMRON的DeviceNet主站连接组成DeviceNet的调试环境。首先在PC机上用C++Builder实现了DeviceNet应用层协议,再将协议的实现代码移植到执行器的控制器。针对智能执行器的特点,设计并实现了一种简单有效的执行器控制方案。设计完成的2个节点与OMRONDeviceNet主站节点连接进行了一致性测试,节点间能可靠通信,结果表明智能执行器的控制方案效果较好。更多还原

【Abstract】 An intelligent actuator based on DeviceNet fieldbus is designed. Its controller,drive cir,cuit and DeviceNet interface are introduced. A PC with CAN interface card is connected to an OMRON’s DeviceNet master to form a design and debugging environment. The DeviceNet applica,tion protocol is programmed and coded in PC using C++ Builder and then downloaded to the controller of the intelligent actuator. A simple and effective control scheme is designed for the intelligent actuator. An intelligent actuator and a PC,based DeviceNet node are connected to an OMRON’s DeviceNet master to test their consistency performance. The result shows its reliable communication and perfect control effect.更多还原
