摘 要

随着USB第一个协议的推出，USB规范稳健发展，USB接口也被广泛

应用。如今，USB已经成为PC上的标准接口，并且大有取代并口和串口之势。在数据采集与传输方面，USB主机通过以太网传输是一个前沿的课题。

为了适应现代数据采集系统朝着强实时，多参数，高精度方向的发展，

以及克服传统单片机数据采集系统无法适应安全性高， 实时性强场合的缺点，本次设计了一种基于TCP/IP终端数据采集与传输模块的系统。本系统以ARM7系列的LPC2210为处理核，以μC/OS-II为操作系统。该系统采用了串口，USB，以太网3种与PC机的通讯方式，以适应不同场合的需要，非常方便。

本次设计主要分为硬件设计与软件设计两部分，其中硬件部分主要包

括以太网模块和USB主机模块的设计，软件部分主要包括μC/OS-II嵌入式操作系统的移植，以太网口驱动和TCP/IP协议栈的实现，USB主机驱动和USB协议栈的实现。

Abstract

. With the USB launched the first agreement, USB stable development of

standardized, USB interface has been widely applied. Today, USB has become

the standard interface on a PC and replace the great potential of serial and

parallel port. In data collection and transmission connection, USB host via

Ethernet transmission is a cutting-edge issues.

In order to adapt to modern data collection system in the strong real-time,

multi-parameter, high-precision direction of development and overcome

traditional SCM data acquisition system can not adapt to safe, real-time

occasions the shortcomings of this design, which is based on TCP / IP terminal

data acquisition and transmission modules of the system. ARM7 family of the

system to the LPC2210 to deal with nuclear, μ C / OS-II for the operating

system. The system uses a serial port, USB, Ethernet and PC three kinds of

means of communication to meet the needs of different occasions, very

convenient.

The design of the hardware design can be divided into two parts and

software design, hardware, including some of the major Ethernet module and

USB host module design, software, including some of the major μ C / OS-II

Embedded operating system migration, Ethernet mouth Driver and TCP / IP

protocol stack to achieve, USB drives and USB host stack of achieving
