毕业论文出租车计价系统作者姓名:专业、班级:学号:校指导教师:校外指导教师:完成日期:黄河水利职业技术学院自动化工程系摘要本设计的是一个基于单片机AT89S52的出租车自动计费设计,附有复位电路,时钟电路,键盘电路等。复位电路是单片机的初始化操作,除了正常的初始化外,为摆脱困境,通过复位电路可以重新开始。时钟电路采用12MHz的晶振,作为系统的时钟源,具有较高的准确性。在上电时字符型液晶1602显示最初的起步价,里程收费,等待时间收费三种收费,通过按键可以调整起步价,里程收费,等待时间收费。通过按键模拟出租车的运行,暂停,停止。在1602液晶上可以显示运行的时间,运行时暂停的时间,通过计算可以得出总共的费用和总的路程。在这里主要是以AT89S52单片机为核心控制器,P0口接1602液晶显示模块,P1口接按键的,通过按键输入。关键词:AT89S52、1602液晶、出租车计费器ABSTRACTThedesignisbasedonamonolithicintegratedcircuitAT89S52taxibillingdesign,withresetcircuit,clockingcircuit,,besidesthenormaloperationoftheinitialdilemma,asaforeigner,,asasystemofcrystaloscillator,,charges,feesmileagewaitingtime,threebuttonscanbeadjustedbychargingfees,justwaitingtime,,buttons,,operationtime,,AT89S52SCMP0mouthafter1602LCDmodule,P1mouthafterthekeys,:AT89S52;1602LCD;Taxidevices目录1课程设计书··································································································································································································································································································································32硬件电路设计···············································································································································································································································································································································································································································································
