基于单片机的公交语音自动报站器系统设计 摘 要 随着我国经济的飞速发展和城市化进程的加深，城市人口日益膨胀，机动车辆急剧增加，城市交通压力越来越大。发展公共交通事业是为居民提供安全有序的出行方式的不可替代的途径，公共交通管理的高质量和公共服务水平的人性化是吸引居民采用公交出行的有效途径，是中国解决交通问题的重要措施。公交车报站系统是公共交通系统的一个重要的组成部分，设计先进的报站系统能为广大居民乘车提供优质的服务，提高公交系统的服务水平。 本设计利用了Atmol公司的AT89C51单片机来设计一个公交语音自动报站系统。用JHD162A LED来提供站台信息的显示；用ISD1700系列语音芯片来对语音进行各种操作控制；并使用DF无线收发模块及PT2262、PT2272编解码芯片来实现信号的无线收发与识别。最后通过AT89C51对各个模块的控制实现无线收发与识别、信息显示及语音报站任务。 关键词：51单片机，ISD1700语音芯片，DF无线收发模块，PT2262/PT2272芯片，JHD 162A， ！！所有下载了本文的注意：本论文附有CAD图纸，凡下载了本文的读者请留下你的联系方式（QQ邮箱），我把图纸发给你。最后，希望此文能够帮到你！ Speech based on single chip bus stop reporter system Abstract With the development of national economy and the deepening of the process of urbanization. The pressure on city traffic is increasing because of the Increasing urban population and the Sharp increase in motor vehicles. Development of public transport is the Irreplaceable way for the Residents safe and orderly travel. The high-quality of Public transport management and public services is a effect way to attract People take bus. and the important measure for China to solve the traffic problems. The bus stop device is a very important Part of Public transport system. The Advanced design of the device can serve people well and improve the Service level of public transportation systems. At present, the city buses have generally installed the station voice system which gives the passengers a very comfortable experience. However, most of the system is manual. The driver have to control it when the car entering and leaving the station. At this time, the traffic condition is so complicated that it usually brings security risks. The paper design a bus automated voice system with Atmel Company’s AT89C51 single-chip. Using JHD162A LCD to display the stations information, ISD1700 series voice chip controls the voice paragraph and DF wireless transceiver module,PT2262/PT2272 chip to achieve the signals wireless transmission and identification. Finally, all the modules are controlled by AT89C51 and the
