摘要
超声波检测迅速、方便、计算简单、易于做到实时控制,且其测量精度能达到工业实用的要求。在超声波硬件电路基础上,重点对声纳的测量特性及其信息不确定性进行了分析,并提出了一种新的超声波传感器模型。该模型在均匀分布超声波模型的基础上,利用概率方法能准确描述声纳扇形范围之内的障碍物位置,通过仿真验证了该模型的有效性和实用性。
Ultrasonic sensor is rapid, convenient, simple to calculate and easy to achieve real-time control. Especially it can achieve the practical requirements in measuring accuracy of industry. Based on the design of ultrasonic hardware circuit, the measuring characterastic and uncertainty of sonar are analyzed, and the new ultrasonic sensor model is introduced. The model can detect the obstacle position in the sector region of sonar based on sonar uniform distribution model. The simulation results indicate that the model is efficiency and applicability.
