基于PIC单片机的出租车计费系统设计

Design for the Taxi Billing System based on the PIC Microcontroller

利用PIC单片机实现出租车计费系统,使其控制系统的启动、停止、复位以及实现计费等功能,时钟芯片PCF8563实时提供时钟信号,再由单片机调用显示;语音播报由语音芯片ISD1420提供语音信息,语音信息放在不同的地址里,由单片机从这些地址中调用合适的语音进行播放,TG12864E液晶模组作为显示器,可以显示数字、字母、中文、图片等。

Using PIC microcontroller implements taxi-billing system,make it control the start,stop,reset of the system and implementing billing and other functions.Clock chip PCF8563 provides clock signal which is displayed by microcontroller;Voice broadcast provides voice information by voice chip ISD1420.Voice information is put in a different address,from which the microcontroller call the appropriate voice to broadcast.TG12864E LCD module is regard as monitor,which can display numbers,letters,pictures,Chinese and so on.
