不斷的完善后可以應(yīng)用到道路檢測,安全巡邏中,能滿足社會的需求。在設(shè)計(jì)上,使用連個傳感器來檢測路面的情況,傳感器的心海比較微弱,采用一個放大器進(jìn)行比較放大,并將其信號輸入到控制器,在受控制端使用步進(jìn)電機(jī),因?yàn)椴竭M(jìn)電機(jī)是用電脈沖進(jìn)行控制的,只要從控制器輸出滿足步進(jìn)電機(jī)功過的固定控制字即可。此外步進(jìn)電機(jī)的運(yùn)作還要一個驅(qū)動電路,故電路中還要加入一個驅(qū)動電路,各個功能模塊對電源電流的要求不同,對電源部分設(shè)置轉(zhuǎn)換電路,從而滿足各個部分的需要。經(jīng)過元件的比較選擇,設(shè)計(jì)出電路原理圖和電路板,并做好硬件的調(diào)試,系統(tǒng)往往是軟件和硬件兩者相結(jié)合的有機(jī)整體。軟件上,使用51單片機(jī)的定時器中斷來控制路面檢測間隔和小車的運(yùn)動及速度。由于帶那路比較簡單,就采用較為傳統(tǒng)的匯編語言進(jìn)行程序設(shè)計(jì)。對于程序設(shè)計(jì)的正確性,用較常用的keilc51仿真軟件進(jìn)行仿真驗(yàn)證,最后便是軟硬件的綜合調(diào)試,證明本設(shè)計(jì)方案的正確性和可行性。2.2電子智能小車的設(shè)計(jì)要求①電動車能夠能夠按照行使路線跑完全程;②電動車能存儲并顯示檢測到的金屬片數(shù)目以及金屬片至起跑線的距離;③要求電動車行使完全程后能夠準(zhǔn)確的顯示電動車全程行使時間;④電動車在行使過程中不能與障礙物碰撞。2.3計(jì)算摘要:本次設(shè)計(jì)的智能循跡小車是以單片機(jī)89c51為主控制器。運(yùn)用反射式紅外傳感器來進(jìn)行路徑檢測和速度監(jiān)測模塊。將檢測數(shù)據(jù)傳回單片機(jī)進(jìn)行處理,同時,用單片機(jī)產(chǎn)生PWM波來控制小車的行進(jìn)速度,并實(shí)時控制小車的行進(jìn)狀態(tài)。另外,在小車上還擴(kuò)展了LCD作為人機(jī)交互界面,以便于實(shí)時了解小車個監(jiān)測傳感器的狀態(tài)機(jī)小車的實(shí)時數(shù)據(jù),由于本次設(shè)計(jì)的是智能自動循跡小車,整個任務(wù)過程無需人工的任何干預(yù),故而沒有進(jìn)行鍵盤及遙控等的人工操作設(shè)備。用多路傳感器的實(shí)時監(jiān)測和算法的緊密
