一种基于激光测距的自动化药房库存盘点方法设计

针对自动化药房储药柜的药品快速盘点问题,设计了一种将激光测距传感器固定安装在机械手上,通过激光测距技术计算药盒数量的方法.采用贝加莱控制系统作为执行机构,上位机软件采用C#作为开发平台,二者采用MODBUS协议通信进行实时信息.上位机采用等代价搜索法对盘点储位进行路径优化,通过RS485通信获取激光测距返回数值来计算储药位药盒数量.实际运行结果表明,该系统可以实现自动化药房的快速盘点问题,并且可靠性高,大大降低了药房盘点的劳动强度.

Design of Automated Pharmacy Stock Inventory Method Based on Laser Ranging

According to the problem of speedy stocktaking of drug which stored in cabinet of automated pharmacy, a kind of method which counts by laser ranging sensor fixed installation on mechanical hand is designed . The PC software adopts C# as development platform, and B&R as control system which communicates with PC by MODBUS communicates protocol. The PC optimizes the path of counting by a method of uniform cost search, and gets counting number by laser ranging sensor which communicates with PC by RS485 communication protocol. The practical running results show that the system with high reliability can realize rapid automated pharmacy inventory problems, and reduce the labor intensity of the pharmacy inventory greatly
