基于多传感器的智能小车避障系统设计

Design of an Avoidance System on the Intelligent Vehicle Based on Multi-Sensors

针对智能小车存在的避障缺陷,设计了一种超声波单点避障与红外双路交叉避障相结合的全方位避障系统,系统以Arduino为主控单元,以Linux为开发平台,通过多传感器数据的采集融合、经由计算机算法控制,可实现全方位自动避障.系统硬件采用多模块协调配合,可使系统具有较高的自适应能力.实验结果表明,设计的全方位避障系统较大地提高了避障的效率和成功率,可有效地实现全方位避障.

In view of the existing difficulties in avoiding obstacle, an all-dimensional obstacle avoidance system is proposed. This system combines the uhrasonic obstacle avoidance at a single point with the infrared detection based on the double cross obstacle avoidance,with the Arduino as the main control unit in the system and Linux as the development platform. The data are collected by multiple sensors, and the intelligent vehicle is controlled by the computer to realize the all- dimensional obstacle avoidance. Multi-module coordination is used in the hardware system with higher adaptive capacity. The experimental result shows the designed system can greatly enhance the efficiency of obstacle avoidance and its success rate,and effectively realize the all-dimensional obstacle avoidance.
