摘　　要：针对MODBUS总线协议设备与以太网通讯互联问题,提出了基于x86处理器的嵌入式网关服务器的硬件设计方法。通过移植μC/OS-II与TCP/IP协议栈实现了协议转换的软件平台,用RTP/C模型成功实现了实时系统的协议间转换。通过组建实验网络环境,验证了嵌入式网关软硬件设计的可行性。The paper presents a hardware design method which realizes an embedded gateway server based on x86 scale to solve the communication matter between MODBUS equipment and Ethernet. RTP/C paradigm realizes real - time system protocol conversion successfully by transplanting μC/OS-Ⅱ and TCP/IP protocol stack. The feasibility of embedded gateway sever is verified by constructing an experiment network system.
