摘要
显示和和控制制终端是“北北斗”用户机的的重要组成部分,用户可以通过终端对“北北
斗”接收机进行精确控制制,同时将获取的的信息准确直直观地显示出来。本文研究了
一种以 Windows CE 为操作系统平台,基于 S3C2440 硬件的的显控系统的的设计与实
现。
本文首先对 WinCE 嵌入式操作系统作一详细介绍,包包括其特点、应用领域、
开发流程及开发工具;其次,根据显控系统的的功功能要求,对硬件平台进行选型,
设计了核心电路系统和和功功能底板电路系统,并详细介绍了这两部分的的模块组成及
各个模块的的功功能。接下来,对显控系统的的软件进行设计,包包括串口通信、数据分
析、人机界面等模块,实现了定位、导航、短信收发等功功能。最后,利用 VC++
在宿主机上开发了一个仿真真实验环境,对已形成的的显控系统进行测试。测试结果
表明,该显控软件具有良好的的人机交互界面、易于操作,定位结果正确,完全满
足系统设计要求。

ABSTRACT
ABSTRACT
Display and control terminal is the ponent of a “BeiDou” user
machine, users can control the “BeiDou” receiver accurately through a terminal, which
can display the information obtained. In this paper, the design and implementation of a
display and control system are studied, based on a WinCE operating system platform
and S3C2440 hardware.
First, this paper introduced WinCE embedded operating system, included features,
applications, development processes and development tools. Secondly, according to the
feature requirements of display and control system, the selection of hardware platform
is made, and core circuitry system and functional backplane circuit system were
designed. Then modules of the two systems and functions of each module are
introduced in detail. Design of the display and control system software, which included
munication, data analysis, human-machine interface, and the functions of
positioning, navigation, SMS are made. Finally, by using VC++ in the host, a
simulation test environment is developed, and the display and control system formed is
tested. Test results showed that the display and control software has a friendly
man-machine interface, which is easy to operate and the positioning results are correct
and meet the system design requirements.
