面向物流终端的包裹分拣装置控制系统的设计

Design of Parcel Sorting Device Control System Oriented to the End of Logistics

以物流终端的包裹分拣任务为背景,设计一种包裹分拣装置控制系统。该系统以STM32F103C8T6单片机为核心,采用条形码扫描仪实现包裹相关信息的采集,利用红外测距传感器GP2Y0A21YK0F实现包裹高度以及真空吸盘空间位置的检测,以矩阵键盘和LCD显示器实现简单的人机交互,结合逻辑门电路与PWM信号控制三维导轨滑台各方向的步进电机进而实现真空吸盘的三维运动控制,从而实现了包裹的自动分拣。通过该装置能够有效减轻物流包裹分拣工作人员的劳动强度,提高分拣时效,降低分拣出错率。试验表明:系统具有可行性和有效性。

This paper introduced a control system of parcel sorting device based on the task of parcel sorting at the end of logistics. In this system the authors took STM32F103C8T6 as processing core,used barcode scanner to pick-up information of the parcel,used distance measuring sensor unit GP2Y0A21YK0F to detect the height of the parcel and the position of the vacuum chuck,used matrix keyboard and LCD display module to realize the human-computer interaction,integrated logic gate circuit and PWM signal to control the stepper motor at the three rail slide in all directions so as to realize the three-dimensional movement of the vacuum chuck control. This device could effectively reduce the labor intensity of logistics parcel sortingstaffs,increase their sorting efficiency and reduce their sorting error rate. The experimental use test results indicated the feasibility and validity of the system.
