摘　　要：介绍了采用模块化设计思想为某电动执行器的变频控制器设计的EPA通信模块。该模块核心为AT91R40008ARM7处理器和AX88796网卡芯片,采用DPRAM实现与变频控制器高速并行数据通信,内嵌μC/OS-Ⅱ实时嵌入式操作系统和EPA工业以太网协议栈。测试结果表明,采用该EPA模块的电动执行器通讯具有较高的精度、实时性和通用性。A EPA standard communication module for the intellegent control device of an intelligent electrical actuator using modular design conception was introduced. In this module,a ARM7 micro -controller AT91R40008 and a network adapter chip AX88796 were adopted, and a DPRAM chip was used for high speed data exchange between DSP and MCU. The real time embeded OS μC/OS-Ⅱ and the EPA real -time industry ethernet protocol software stack were also adopted. It was proved that electric actuator with this EPA communication module had higher precision and real - time, and more applicability.
