摘  要

 隨著科學技術和地理信息系統的發展，計算機的發展已經進入了移動時代，以掌上電腦（PDA）為代表的移動嵌入式產品日益普及，在移動中使用計算機，將移動的主體通過網絡與龐大的數字空間無縫結合在一起，已經不再是天方夜譚。個人移動導航為主的PDA嵌入式產品在未來的市場具有巨大的發展潛力。
 課題結合嵌入式系統技術，以UP-TECH270-S為硬件開發平臺，采用Windows CE5.0操作系統，qt-embedded-wince-opensource4.6為應用程序框架設計的智能PDA終端，它作為智能PDA手持GPS終端的一個重要組成部分，主要是利用正在興起的移動計算機技術、GPS導航技術，結合個人數字助理等開發設計的嵌入式空間信息可視化應用系統，該系統具有傳統的空間信息顯示、查詢、分析等功能，更重要的是，它一方面是移動系統，能夠隨時隨地的使用，另一方面是能適應各專業領域的應用（如智能家居，車載信息系統等設備），本項目的GPS導航、無線通訊、Qt應用程序設計是本課題的重點。
 本畢業設計論文主要從發展前景、系統方案、硬件設計、軟件設計、實現功能、實現原理、系統測試等方面詳細深入的闡述智能PDA終端開發的整個流程和細節。

PDA Design and Implementation of Intelligent Terminal
ABSTRACT

 As science and technology and the development of geographic information systems, computer's development has entered the mobile era, Yi Pocket PC (PDA) as the representative of the mobile embedded growing popularity in the use of mobile Zhong computers, mobile's Zhuti by Wang Luo and large seamless combination of digital space is no longer a fantasy. PDA-based personal navigation products in the future market of embedded has great potential for development.
 Combination of embedded system technology subject to UP-TECH270-S for the hardware development platform, using Windows CE5.0 operating system, qt-embedded-wince-opensource4.6 application framework for the design of intelligent PDA terminal, which as a smart handheld PDA GPS terminal is an important component Bufen, mainly the use of emerging mobile computer technology, GPS navigation technology, combined with personal digital assistant and other development Sheji the embedded application space information visualization system, which has the space for information display Chuan Tong, query analysis and other functions and, more importantly, it is a mobile system on the one hand, the use of anytime, anywhere, on the other hand is able to adapt to the application of various professional fields (such as smart home, vehicle information systems and other equipment), the project including GPS navigation, wireless communications, Qt application design is the focus of this issue.
 The design report mainly from the development prospects of the system, the hardware design, software design, implementation, and realize the principle of system testing are also described in detail the development of smart PDA devices and details the entire process.
