超声波传感器环系统设计

Central ultrasonic sensor system design

在自主移动机器人的避障导航中,精确实时探测周围环境信息传感系统至关重要。提出一种基于89s52单片机,多超声波的环境探测器,通过CAN总线,用SDS协议与其他模块通讯,采用分组循环启动的方法大大降低了超声波之间的串扰问题.并对传感器环进行了标定,标定结果证明该传感器环具有较高的精度和较好稳定性。

In the autonomous mobile robot obstacle avoidance navigation, accurate, real-time detection system sensor information surrounding environment is essential, the paper proposes a 89 s52-based microeontroller, multi-ultrasonic system, It can communicate with other module through CAN bus with .multi-ultrasonic grouped-cycling sending method is used to reduce the interference between sensors, sensor calibration results show that the sensor ring has higher precision and better stability.
