摘要:

设计了一种以Cortex-M4微控制器STM32F407为核心,采用超声相控阵技术对障碍物进行探测的系统。实验结果表明,该系统聚焦探测区域的实际声场强度大于常规的超声波技术,声波能量更为集中。系统的探测范围在0.3~5.5 m,探测精度±1 cm,稳定性好,准确方便。

关键词: Cortex-M4, 超声相控阵, 探测

Abstract:

We design an obstacle detection system with ultrasonic phased array detection and  the microcontroller Cortex-M4 as a processor. Experiments show that the actual sound field strength of the focal area is greater than that of conventional ultrasonic technology and sound energy is more convergent. Its detection distance is from 0.3 to 5.5 m, and measurement accuracy is ±1 cm. The system is therefore effective and satisfactory.

Key words: detection, Cortex-M4, ultrasonic phased array
