毕业设计（论文） 论文题目：基于网络的数据采集系统 摘 要“数据采集”是指将温度、压力、流量、位移等模拟量采集转换成数字量后，在由计算机进行存储、处理、显示或打印相应的系统称为数据采集系统。本文简要介绍了嵌入式TCP/IP协议单片机在网络通信中的数据传输技术。将TCP/IP协议嵌入到单片机中， 借助网卡芯片ZNE--100 实现了单片机在局域网内和通过局域网在因特网上的数据传输。用户终端以单片机系统板为媒介，通过网络与远程数据终端实现数据通信。 关键词：TCP/IP协议 单片机 因特网 局域网 网卡芯片ABSTRACT"Data Acquisition" refers to the temperature, pressure, flow, displacement, such as analog-digital conversion acquisition, by the computer storage, processing, display or print the corresponding system known as the Data Acquisition System. This paper introduces the embedded TCP / IP protocol SCM in the data communications network transmission technology. Will be TCP / IP protocol embedded in the microcontroller, with chip card ZNE - 100 realization of the SCM in LAN and through LAN Internet data transmission. User terminals to SCM system board for the media, through the network and remote data terminals for data communications.
