摘  要
 城市的發(fā)展日新月異，隨著許多新建小區(qū)大量出現(xiàn)，公交線路也日漸增多，給人們的出行帶來了極大便利的同時(shí)，也給人們?nèi)绾芜x擇出行乘車線路造成一定的困難，特別是在旅游城市尤其如此。因此，開發(fā)智能化的公交站牌系統(tǒng)非常必要，它不僅可以給市民游客的乘車提供向?qū)В�同時(shí)可以對外展現(xiàn)城市的現(xiàn)代風(fēng)貌，體現(xiàn)出一個(gè)城市公交信息數(shù)字化和信息化的發(fā)展水平。
 基于ZigBee無線網(wǎng)絡(luò)的智能公交站牌系統(tǒng)作為一個(gè)有實(shí)際意義的嵌入式電子產(chǎn)品，也是很多公共場所的必備產(chǎn)品，用途十分廣泛。智能公交站牌系統(tǒng)能幫助人們方便查詢公交線路，提供許多當(dāng)?shù)氐穆糜沃改希�給乘客帶來了極其方便，滿足了人們生活的需求。本人所開發(fā)的“基于ZigBee無線網(wǎng)絡(luò)的智能公交站牌系統(tǒng)” 通過在UP-TECHPXA270-S硬件平臺上移植Linux 2.6.9 內(nèi)核的操作系統(tǒng)，使用Qt4編程語言來開發(fā)智能公交站牌系統(tǒng)相關(guān)應(yīng)用層軟件，實(shí)現(xiàn)了公交查詢的完整功能，公車到站提醒報(bào)站系統(tǒng)，同時(shí)具有音視頻播放、IC卡查詢、旅游導(dǎo)航等功能，還可以查看近日的天氣情況。
 本文論述了設(shè)計(jì)開發(fā)基于ZigBee無線網(wǎng)絡(luò)的智能公交站牌系統(tǒng)在Linux平臺上的完整實(shí)現(xiàn)方案。

ABSTRACT

 The rapid development of the city, with many new community copious, bus lines also grows, people travel has brought about tremendous convenience at the same time, also how to choose a trip by bus line caused certain difficulties, particularly in tourist areas. Therefore, the development of intelligent bus transit system is essential, not only to public visitors travelling provides Wizard, at the same time can reveal the city's modern style, reflect an urban public transport information in electronic and information technology to the level of development.
 Based on ZigBee wireless network of intelligent public transport operating system as a practical embedded electronics, too many public places of essential products, uses. Smart bus transit system will help people easily query bus lines, provides a number of local tourism guide, giving passengers a tremendous convenience to meet the needs of people's lives. I have developed "based on ZigBee wireless network operating system for smart bus" by UP-TECHPXA270-S hardware platform Porting Linux 2.6.9 kernel of the operating system, use the Qt4 programming language to develop smart bus transit system related application layer software, enable the full functionality of transit query, the bus to stop alerting systems, both audio and video playback, IC card queries, tourism navigation capabilities, you can also view recent weather conditions.
 This article discusses the design and development based on ZigBee wireless network operating system for smart bus on the Linux platform of full implementation.
