公交车报站系统的设计.doc

摘 要：随着科学技术的日益发展和进步, 无人售票公交车在街头多起来了，语音报站器也被广泛使用，这在相当大的程度上免除了乘务人员沿途报站的麻烦，给许多不熟悉公交线路的乘客带来了方便。

　　　本设计采用单片机SCT89C52作为控制核心，语音芯片ISD1700实现语音的存储和回放，LCD12864进行汉字显示，设计了公交车控制报站系统，实现了公交车站台语音播报、液晶显示和站台语音播报与液晶显示双重功能。

　　　系统主要通过STC89C52单片机做为主芯片，启动LCD12864显示站名，同时应用语音模块播报站名。整个系统硬件设计包括键盘控制模块、语音播报模块、液晶显示模块。

Abstract：Along with the science and technology development and progress, unmanned bus in the street up, the voice stops were also widely used, this to a great extent from crew of the stops along the way trouble, give many not familiar with the bus lines passengers brought convenient. 

   This design USES the monolithic SCT89C52 as control core, voice chip ISD1700 realize voice of storage and playback, LCD12864 display on Chinese character, design the bus stops control system, realize the bus station speech broadcast, liquid crystal display and platform speech broadcast and liquid crystal display double function. 

    The system mainly through STC89C52 microcontroller do give priority to chip, start LCD12864 display name, at the same time, the name of the pronunciation module. The whole system hardware design including the keyboard control module, speech broadcast module, liquid crystal display module.
