基于C8051F310的高灵敏车辆检测算法

Algorithm of high sensitive vehicle detection based on C8051F310

针对盘山路存在的转弯盲区,即在转弯时司机无法得知弯路对面是否有车辆通过,设计一种基于C8051F310的山路转弯预防警示系统。该系统利用一阶滤波算法检测山路转弯时是否有车辆通过。运用该算法可增强系统检测的实时性,提高检测机动车辆的灵敏度,同时大大减少环境温度对检测的干扰。试验表明该系统能够正确指示出在山路转弯时是否有车辆通过,目前该系统已安装在盘山路上,可大大减少事故的发生率。

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 system 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 environmental temperature.The experimental results show that this system can exactly indicate if there are passing vehicles.At present, the system has been suecessfnlly applied to hilly road. The system can greatly decrease accident.
