摘要
目的结合飞思卡尔全国智能车大赛,介绍一种基于红外反射式光电传感器路径识别的智能车控制系统;方法利用10路红外光电传感器构成光电传感器阵列采集路面信息,采用霍尔式速度传感器采集小车速度信息;结果单片机获得路径信息和车速信息后,用以控制智能车的舵机转向,同时对电机进行调速,实现智能车沿着既定的跑道自主运行;结论试验证明,系统能够较好地满足智能车对路径识别和稳定性的要求,具备一定的抗干扰能力,能够快速平稳地自动寻迹行驶。
Aim To introduce a smart car control system based on infrared reflective photo-sensor in the national Freescale Smart Car Contest.Methods Road surface information is collected through photo-sensor array composed of ten infrared photo-sensors.Car speed information is collected through Hall sensor.Results After obtaining route information and car speed information,SCM controls the steering of smart cars and adjust the speed of motor,thus enabling smart cars to run independently along the given course.Conclusion Tests prove that the system can well meet smart cars' requirements for route identification and stability,and can resist disturbance and rapidly seek for tracks.
