摘要

本设计为了方便旅游导游车的旅游站点信息指导，能够准确提醒游客所到的旅游景点目的地。系统设计采用语音播报，模拟清晰人声进行旅游景点站的信息播放，而且能够同步用文字显示该旅游景点的名称和具体信息。本设计根据旅游车的实际应用情况，把液晶景点站点信息显示、无线接收信息、景点站点信息的语音播放整合成一个完整的系统，在设计方面考虑人性化。旅游景点信息由信号发射模块预先设定，采用微型射频发射，信号覆盖范围能达到几十米到两百米，接收模块通过接收信号，解码芯片对接收的信号进行解码，可读取接收器正在靠近的所在旅游景点信息。语音模块经过功率放大器和喇叭，播放站点信息，同时，液晶模块对旅游景点信息进行准确的显示。

本文简要讲述包括硬件规划和软件的架构流程。通过合理的方案实现旅游景点信息的播报和显示，方便及时提醒旅客即将到达的旅游站点。

Abstract

The design for tourist site information easy guide tour guide car, can accurately to remind visitors to tourist destinations. System design using voice broadcast, tourist attractions station information playback simulation clear voice, but also can synchronize text display name of the tourist attractions and the specific information. This design according to the practical application of the coach, voice the liquid crystal attractions site information, wireless receiving information, scenic site information playback integrated into a complete system, consider in the design of human nature. The information of tourist attractions set is composed of a signal transmitting module, the micro RF, signal coverage can reach several tens of meters to two hundred meters, the receiving module uses the received signal, decoding chip decodes the received signal, the receiver can read is close to where the tourist information. The voice module through the power amplifier and the loudspeaker, playing site information, at the same time, accurate display of tourist information LCD module.

This paper briefly describes the structure of hardware and software of process planning. Realize the information of tourist attractions through the reasonable scheme of broadcast and display, convenient and timely to remind visitors will arrive at tourist sites.
