基于北斗定位的港口堆取料机防碰撞系统关键技术研究

Research on Key Technologies of Anti-Collision System of Port Stacker-Reclaimer Based on Beidou Positioning

堆取料机作为港口散货物流运输环节的核心设备,实现其自动定位和防碰撞,可有效提高生产效率及作业安全性,降低操作人员劳动强度。通过北斗差分定位技术、RFID技术及毫米波雷达的冗余结合,实时计算出堆取料机悬臂在堆场空间坐标系下的相对位置和距离,可实现堆取料机悬臂厘米级自动定位防碰撞闭环控制、自动协调多台堆取料机在同一个堆场中安全作业。

Stacker-reclaimer,as the core equipment of the port bulk cargo flow transportation,realizes its automatic positioning and anti-collision,which can effectively improve production efficiency and operational safety,and can effectively reduce the labor intensity of operators.Through the redundant combination of Beidou differential positioning technology,RFID technology and millimeter wave radar,the relative position and distance of the stacker-reclaimer cantilever in the yard space coordinate system can be calculated in real time,which can realize the centimeter-level automatic positioning and prevention of the stacker-reclaimer cantilever.Collision closed-loop control and automatic coordination of multiple stacker-reclaimers to operate safely in the same yard.
