In order to improve the technology of the simulator input&. Output interface system based on serial communication bus in a low communication rate, the distribution of the limited distance and difficult to debug, a distributed intelligent input &- output interface system based on the ARM and Ethernet technology is proposed. The design and implementation of a intelligent input&- output interface system based on embedded microprocessor chip ARM and Ethernet technology is introduced, including the system design, the hardware realization, definition of the table of the configuration and I/O management &- communication software, etc. The hardware and software of this I/O interface system is debugged and run, and the result indicates that this 1/ 0 interface system have a high data transfer rate , a big range of the distributing, and also can easily expand, this I/O interface system meets the design and application requirement of simulation system.%为了改善基于串行总线技术的电站仿真机接口系统通信速率低、分布距离有限、扩展不方便以及调试困难,提出了基于ARM技术和以太网技术的分布式智能化输入输出接口系统.基于提出的分布式仿真机接口系统思想,分别从系统设计、系统软硬实现以及组态设计等进行了设计和实现.系统实际应用表明,基于ARM技术和以太网技术的接口系统通信速率高、分布距离远和扩展更方便,能够满足电站全范围仿真机输入输出接口的需要.
