軟件：Quartus

語(yǔ)言：VHDL

代碼功能：

出租車自動(dòng)計(jì)價(jià)器設(shè)計(jì)

設(shè)計(jì)一個(gè)杭州市臨安區(qū)出租車計(jì)價(jià)器。

該計(jì)價(jià)器的計(jì)費(fèi)系統(tǒng):行程4公里內(nèi),且等待累計(jì)時(shí)間1分鐘內(nèi),起步費(fèi)為10元;4公里外以每公里2.5元計(jì)費(fèi),等待累計(jì)時(shí)間2分鐘外以每分鐘以2.5元計(jì)費(fèi)，并能顯示行駛公里數(shù)、等待累計(jì)時(shí)間、總費(fèi)用。

主要技術(shù)指標(biāo)

①計(jì)價(jià)范圍:0~999.9元計(jì)價(jià)分辨率:0.1元

②計(jì)程范圍:0~99公里計(jì)程分辨率:1公里

③計(jì)時(shí)范圍:0~59分? ? 計(jì)時(shí)分辨率:分
