摘 要
电子导游机最开始时是一种半自动化系统，它的功能只是把景点信息以语音文件格式存储在导游机里，一般通过键盘直接键入景点代码，选择播放。全自动化的电子导游系统，它在景点先安放无线发射模块，这些发射模块可以控制工作范围，这样在各个景点就有不同的编码信号。游客到达景区某个景点后，游客手上的导游机会自动接收编码信号，经过解码后，由控制中心控制语音播放即可。当有紧急事件是有GSM模块发送信号通知。系统电子导游机的硬件采用51系列的单片机作为控制中心，语音模块miniC-A101FS进行语音播放，编解码芯片SC2262／SC2272进行无线收发信号的编解码，GSM模块使用TC35i模块进行紧急拨号。

Abstract
Most e-start guide machine is a semi automated system, its function is to spot a voice file format information stored in the guide unit, the general attractions through the keyboard by typing the code, select Play.Tourists in this article guides the hands of the electronic control unit using the serial port voice module miniC-A100FS, microcontroller 51 using more generic AT89C51 MCU as a system of control processing unit, codec chip SC2262 /SC2272 and the GSM module TC35i module.Electronic guide automation system, which placed first in spot radio transmitter module, the transmitter module can control the scope of work, so there are different spots in each coded signal.Visitors reach the attractions, visitors guide the hands of the opportunity to automatically receive encoded signals, after decoding by the control center can control the audio playback.When an emergency is to send signals to the GSM module.
