摘　　要：文章介绍了一种基于单片机ADμC834和以太网控制芯片RTL8019AS的测控节点的硬件架构,该节点包含模拟量输入、开关量输出和越限报警等功能模块。本节点以嵌入式μC/OS-Ⅱ为操作系统,以uIP为以太网协议栈,节点在多任务环境和以太网通信的支持下可顺利地执行模拟量采集、控制量输出、以太网通讯和越限报警等任务。The paper introduces a hardware structure of an ADμC834 and RTL8019AS based monitoring node that includes such modules as analogy input, digital output and limits alarming. With the embeddedμC/OS-Ⅱ as the operating system and uIP as the Ethernet protocol stack, the node can smoothly handles such tasks as analogy data acquisition, control action output, Ethernet communica- tion and limits alarming under the multi-tasking environment and with the Ethernet communication facility.
