| 摘要：电子标签辅助选取是目前倡导的现代智能化物流系统无纸化作业的重要技术，其原理是在每一个货位上安装电子标签，PC机通过总线网络将订单信息传输到电子标签，拣货人员根据电子标签显示的货品数量进行选取,选取完货品后按确认键完成工作。该系统可以弹性地控制选取的流程，加快选取的速度，提高了工作效率，降低错误率，消除传统作业的不便，节省了人力作业和培训的成本。 本文介绍了一种基于CAN总线的现代智能化物流电子选取系统，在设计中采用Maxim公司的MAX232集成芯片作电平转换器，Philips公司的TJA1050T CAN总线控制器等器件，主控制器采用高性能的PIC单片机，它在系统中扮演者一个桥梁和协调控制的作用。本课题的设计使在大规模地安置电子标签、大范围地增加货品选取种类、提高信息传输的速率、降低物流选取系统的成本成为可能。5353 关键词： 智能物流；选取系统；CAN总线；电子仿真 Simulation of Electronic Eelection of Intelligent Logistics System Abstract: RFID-assisted selection is currently the advocacy of modern automated logistics system of paperless operations underlying technology, the principle is in each install electronic shelf labels, order information is transmitted over the network to the computer electronic label, picking personnel selection according to the electronic label displays a quantity of goods, picks up after you finish press the Confirm button is to complete its work. The technical requirements are: TL lighting system chosen, through digital technologies to manage the picking process, to achieve standardization and simplification in order picking to increase picking efficiency.The system can be flexibly control the process of picking, increase picking speed, reduce error rates, eliminating inconvenience of traditional job, time and cost savings in human resources and related staff training. Describes a chosen system CAN bus in intelligent logistics of modern electronic technology in the simulation, the layout tag placed on a large scale and widespread increase in the goods chosen species, enhance the rate of information transfer, reduce the cost of electronic order picking systems possible.
