【摘要】：针对目前智能避障小车存在障碍物距离测量精度不高,存在探测盲区的问题,介绍了一种基于Arduino的智能避障系统。常见的超声波避障模块探测距离远不易受到干扰,但是反应时间长。红外测距探测距离近,测量速度快,精度高,但是受环境影响较大。利用Arduino作为主控系统,采用超声波测距、红外测距等多传感器信息融合的采集系统,优势互补,并通过对数据的算法优化,提升小车对环境的感测精度,有效提高了小车的避障成功率。基于Android开源平台的蓝牙串口通信APK,智能小车既可以自动避障,也可以接受人的帮助,进行人工避障,实现了手动和自动双操作模式,丰富了用户体验。实验证明,该系统运行稳定,对障碍物的探测更加精确,可有效实现全方位避障。
[Abstract]:An intelligent obstacle avoidance system based on Arduino is introduced to solve the problem that the measuring precision of obstacle distance is not high and the blind area is detected in the intelligent obstacle avoidance vehicle. The detection distance of the common ultrasonic obstacle avoidance module is far from being disturbed, but the reaction time is long. Infrared ranging is very close, fast and accurate, but it is greatly affected by environment. Using Arduino as the main control system, the acquisition system of multi-sensor information fusion, such as ultrasonic ranging, infrared ranging and so on, has complementary advantages, and through the optimization of the data algorithm, it can improve the precision of the car's sensing to the environment. The success rate of obstacle avoidance is improved effectively. Based on Android open source Bluetooth serial port communication, the intelligent car can avoid obstacle automatically or accept the help of human. It realizes manual and automatic double operation mode, and enriches the user experience. The experimental results show that the system is stable and more accurate in detecting obstacles, and can effectively avoid obstacles in all directions.
