基于激光测距的车载沙石体积测量系统

摘要

车载沙石的体积测量对于控制混凝土的生产成本以及质量都具有重要意义.在系统中,x-y平面旋转和y-z平面偏转配合工作机构实现了一个激光测距仪对沙石表面扫描测量,延时策略简单有效地保证了电机运动和激光测距的协同工作,边界判断方法能有效地筛除测量过程中产生的无效数据.工业应用表明:采用机械、测控、软件技术实现的车载沙石体积测量系统能够解决车载沙石的体积测量问题.%The sand and gravel are main raw materials of ready-mixed concrete which is basic material for national construction. The volume measurement of truck loaded sand and gravel is important for the quality and costs control of ready-mixed concrete. In this system,the mechanism of x-y plane rotation cooperative with z-direction deflection realized that one laser range instrument scaned the sand and gravel surface,and the delay strategy made the motor motion and range measurement working together simply and efficiently, and boundary determination strategy removes the invalid measuring data efficiently. The appellation cases show that the system,which is implemented by making use of mechanics,control and measurement,software technology synthetically , can measure the volume of the truck loaded sand and gravel accurately.
