摘要
针对智能小车在实际应用中的需要,设计了一种基于ARM和Linux的具有路径记忆循迹功能的智能小车。利用ARM和Linux操作系统,实现了对智能小车的超声波避障模块、电机等的控制。利用电子罗盘,实现了小车在无黑线情况下精确转向;利用超声波测距避障以及Linux文件系统建立和保存了智能小车运行的路径记忆库;通过读取记忆库的数据实现智能小车的循迹功能。结果表明,该设计方案可以很好地实现循迹功能并且对环境的适应性较强。
Aiming at the practical application, a smart car based on ARM and Linux is designed, which has the function of path tracking memory. The design uses the ARM and Linux operating system to achieve the control of ultrasonic obstacle avoidance module and motor module. The car realizes accurate steering without black line using the electronic compass. A running state memory bank of the ear is es- tablished using the ultrasonic obstacle avoidance and Linux file system. Then it achieves intelligent car tracking function by reading data from memory bank. The experimental results show that the scheme can realize tracking function and has strong adaptability to the envi- ronment.
