針對盤山路存在的轉(zhuǎn)彎盲區(qū),即在轉(zhuǎn)彎時司機無法得知彎路對面是否有車輛通過,設(shè)計一種基于C8051f310的山路轉(zhuǎn)彎預(yù)防警示系統(tǒng)。該系統(tǒng)利用一階濾波算法檢測山路轉(zhuǎn)彎時是否有車輛通過。運用該算法可增強系統(tǒng)檢測的實時性,提高檢測機動車輛的靈敏度,同時大大減少環(huán)境溫度對檢測的干擾。試驗表明該系統(tǒng)能夠正確指示出在山路轉(zhuǎn)彎時是否有車輛通過,目前該系統(tǒng)已安裝在盤山路上,可大大減少事故的發(fā)生率。
Abstract:
Aiming at passing hilly road,there is a turn blind spot.Motormen usually do not know if the passing of vehicles pass the road.So a system of defending accident on hilly road is designed,which is based on MCU C8051f310.The sys-tem uses the first-order filter algorithm to detect whether there are passing vehicles.This algorithm enhances the real-time detection and improves the sensitivity of detection vehicles.Meanwhile,it reduces the detection interference of environmen-tal temperature.The experimental results show that this system can exactly indicate if there are passing vehicles.At present,the system has been successfully applied to hilly road.The system can greatly decrease accident.
