公交车报站系统的设计说明

公交车报站系统的设计[摘要]当今社会，对于一些学生和一些上班族来说，公交车成为了一种必不可少的交通工具。目前，就我们所在地来说，公交车一般采纳的是手动报站系统，这样，就给司机增加了一些困难和劳动强度，也为乘客的安全增加了一些隐患。假如道路复杂的情况下，司机忘报站或错报站这类失误往往还会给乘客造成一些不必要的麻烦。本设计运用 AT89C51 单片机来实现公车的自动报站功能，使公交车在快到达每一个站点的情况下自动进行语音报站，并且把站台名字显示在 LED 数码管上。本系统利用 AT89C51 作为主控芯片来完成主控电路的设计，语音电路、汉字点阵显示电路、电源电路作为辅助电路等，主要实现到站自动报站自动显示站点。[关键词]：自动报站、80C51 单片机、语音电路、LED[ABSTRACT]In today's society， to some students and some office worker， bus becomes a necessary means of transportation. At present in our location， the bus usually adopts automatically stops,which increases some difficulties and labor strength of drivers and some risks of passengers. Under the complex road circumstance, drivers may forget to stop or stop by mistake, which will cause some unnecessary troubles.This design uses single-chip microcomputer AT89C51 to realize the automatic bus stops function ，which makes bus in quick arrive every site under the condition of the automatic for voice stops ， and put in LED digital display platform name tube. This system is required to exploit the AT89C51 as the master chip to complete the main control circuit design ， voice circuits， Chinese characters dot matrix display circuit， the power circuit as auxiliary circuit ， etc. ， and it mainly realizes automatic station stops and automatic display site.
