基于无线通信技术的电子导游系统的设计与实现
中文摘要
随着旅游业的蓬勃发展,以及个性化导游的趋势,传统的人工导游已不能很好地 满足游客的需求。另外,随着无线通信技术、计算机技术和电子技术等高新技术的迅 猛发展,各种电子导游系统也应运而生。本课题从实际需求出发,主要研究一种基于 无线通信技术的电子导游系统。
本文首先了解了电子导游系统国内外的研究进展和发展趋势,同时深入分析了电 子导游系统在旅游业中的具体需求和应用环境,并对所设计的电子导游系统的技术框 架、功能需求、主要技术指标等进行了系统地分析。
整个系统硬件部分主要包括无线射频基站和电子导游机两部分,无线射频基站被 预先设置为唯一的编号,放置于景区内需要讲解的景点,并持续发送编号信息。当游 客进入到某一景点无线射频基站所覆盖的范围内,其身上所携带的电子导游机就会接 收到该基站发送的编号信息,同时,电子导游机内的预置应用处理程序会根据编号, 自动从 SD 卡中寻址并调出相应的 MP3 格式的语音文件,再由 MP3 模块对语音文件 进行解码,并输出到语音播放模块,播放该景点的讲解信息。
然后,按照系统软件设计原则详细设计了 nRF24L01 软件、无线射频基站软件和 电子导游机软件。
最后,从无线通信距离和系统功耗两方面对整个系统做了详细的测试,得到了实 测数据,并对数据进行了分析总结,结果表明,本文设计的电子导游系统符合设计需 求。

The Design and Implement of Electronic Guiding System Based on Wireless Communication Technology
Abstract
Because of the rapid development of tourist industry and the appearance ofpersonalized guide ,the traditional artificial guide has been unable to meet the requirements of tourists.In addition,with the rapid development of wireless communication technology,
computer technology, electronic technology, and so on, a variety of electronic guiding systems are born at the right moment.According to actual demand, a electronic guiding
system based on wireless communication technology is been researched in the paper.
Firstly, the research progress and development trend about electronic guiding system in the domestic and foreign are understood, at the same time, the specific needs and application environment of electronic guiding system in tourism industry are in-depth analysed, and system technical framework, functional requirements and main technical index of the electronic guiding system, which is designed in the paper, is also researched.
The hardware of the system comprises wireless RF base station and electronic guiding machine, in advance, wireless RF base station is set for the unique
