摘要
本文提出一种新的智能小车主动及被动控制手段,采用STC89C51RC与K66双芯片实现对智能小车的控制.运用蓝牙通信技术实现通过手机端APP控制小车进行基本动作,同时利用超声波测距技术实现小车自动避障.此外,还加入了红外探测传感器以实现小车的自动循迹,结合低功耗的MT9V032摄像头,利用图像识别技术实现了信标灯寻的.实验测试结果表明该移动小车在光照条件适当的情况下具备良好的循迹性能,在小车速度为20 cm/s时避障准确率达到99%,能够以3.1 m/s的稳定速度识别到直径为7.85 m辐射范围内的信标灯.
In this study,an active and passive control method of intelligent cars is proposed.The STC89C51RC and K66 dual chips are used to control intelligent cars.With the Bluetooth communication technology,the car is controlled on a mobile phone APP.Meanwhile,automatic obstacle avoidance of the car is achieved with the ultrasonic ranging technology.In addition,an infrared detection sensor is added to facilitate the automatic tracking of the car.Beacon light homing is accomplished with the image recognition technology and the low-power MT9V032 camera.The experimental results show that the mobile car delivers a good tracking performance under proper lighting conditions.When the speed of the car is 20 cm/s,the obstacle avoidance accuracy reaches 99%and beacon lights within 7.85 m away from the car can be identified at a stable speed of 3.1 m/s.
