摘　　要：提出一种基于AT89C51RC单片机和RTL8019AS网络驱动芯片的以太网数据采集器的设计方案,介绍其软硬件结构。重点介绍系统软件各个子模块的设计。数据采集器以AT89C51RC为核心,嵌入TCP/IP协议栈,实现对智能仪表数据的采集、存储和以太网传输等任务。该数据采集器的功能已在建筑能耗数据采集系统中得到验证。An Ethernet data acquisition system was designed based on AT89C51RC MCU and RTL8019AS chip. Its software and hardware structures were introduced. The design for every sub-module in software system was introduced mainly. The data acquisition system was composed of AT89C51RC MCU as its hardware core and embedded TCP/IP protocol stack, and implemented tasks of data acquisition, storage and Ethernet transmission from intelligent instrument. Its function was verified in building energy consumption data acquisition system.
