摘要:隨著城市建設(shè)日益加快，象征著城市面貌的出租車行業(yè)也將加速發(fā)展?，F(xiàn)在各大中城市出租車行業(yè)都已普及自動(dòng)計(jì)價(jià)器，所以計(jì)價(jià)器技術(shù)的發(fā)展有很好的前景。盡管小城市尚未普及，但計(jì)價(jià)器的普及也是毫無(wú)疑問(wèn)的，所以未來(lái)汽車計(jì)價(jià)器的市場(chǎng)還是十分有潛力的。 出租車計(jì)價(jià)器是單片機(jī)的一種典型應(yīng)用?；趩纹瑱C(jī)的計(jì)價(jià)器是由單片機(jī)和外部電路組成。包括檢測(cè)模塊，控制模塊，人機(jī)模塊。里程檢測(cè)模塊和紅外對(duì)側(cè)傳感器構(gòu)成，控制模塊包括STC89C52單片機(jī)和紅外對(duì)側(cè)傳感器，人機(jī)模塊包括獨(dú)立鍵盤和LED動(dòng)態(tài)顯示。 關(guān)鍵詞：STC89C52；紅外對(duì)側(cè)傳感器；獨(dú)立鍵盤和LED顯示
ABSTRACT:Along with the city construction is accelerating, symbolizing the city landscape taxi industry will also accelerate the development of. It is now the major city taxi industry have universal automatic meter, meter technology development has a very good prospect. Despite the small city has not yet universal, but the popularity meter is no doubt, so the future of the automobile market valuation is still potential. MCU Taximeter is a typical application of. Based on microcontroller Taximeter is composed of a single-chip microcomputer and the external circuit. Includes detection module, control module, man-machine module. Mileage detecting module and an infrared sensor. On the side, the control module includes STC89C52 SCM and infrared contralateral sensor, man-machine module includes independent keyboard and LED dynamic display. Key words: STC89C52; infrared sensor on the side; independent keyboard and LED display
通過(guò)對(duì)基于Proteus 7.5的仿真和實(shí)際電路的測(cè)試結(jié)果分析，表明用此方法設(shè)計(jì)的計(jì)價(jià)器。實(shí)現(xiàn)了計(jì)價(jià)功能，此外還增加了等待計(jì)時(shí)功能，，并且能實(shí)時(shí)顯示總金額，運(yùn)行單價(jià)等詳細(xì)信息；且能很方便的在不改變硬件電路的情況下通過(guò)改變軟件實(shí)現(xiàn)計(jì)價(jià)精度的提高，進(jìn)行功能上的擴(kuò)展，如可把現(xiàn)有的計(jì)價(jià)器轉(zhuǎn)變?yōu)橛?jì)速器，完善的功能使得基于STC89C52單片機(jī)的出租車計(jì)價(jià)器的通用性和實(shí)用性有著無(wú)可比擬的優(yōu)勢(shì)，具有很高的現(xiàn)實(shí)意義和很好的市場(chǎng)前景。
