摘要：针对电子装备生产企业物料中心信息系统覆盖不足、软件支撑能力薄弱等问题，提出一种新的物料出入库智能指示系统，实现信息流对物料出入库环节的覆盖。构建平库管理数据库，将物资系统生成的物料出入库清单实时传递给上位机软件，实现物料出库信息在线提取与状态辨识以及物料入库库位智能分配，数据库同时进行在线动态更新。基于485总线实现上位机与单片机的多机通信，通过亮灯方式让业务人员直观获知工作指令，准确快速地完成物料出入库任务。

Abstract： A new intelligent indication system for material in and out-of-warehouse is proposed to overcome the problems ofinsufficient coverage of the material centre information system of electronic equipment manufacturers and weak software supportcapabilities. Firstly， a warehouse management database is built. Secondly， the material in and out-of-warehouse list generated by thematerial system is transferred to the host computer software in real time to realize online extraction and status identification of materialout-of-warehouse information and intelligent distribution of material in-warehousing locations. and the database is updated online. Afterthat. the multi-machine communication between the host computer and the single-chip computer is realized based on the 485 bus.Finally， the operators are intuitively informed of the work instructions through the method of lighting， and the task of material in andout-of-warehouse c an be completed accurately and quickly.

0引言

原材料、辅料以及各类备品备件是我国科研产业结构升级的重要载体和装备制造的物质基础，也是装备制造企业正常生产的物质保障[1]。随着电子装备领域多样化需求模式的产生，电子设备更加趋向于多品种小批量的生产模式。因此，提高物料出入库的快速性和准确性对于保障物料中心业务人员的作业效能、提高产品的生产效率具有重要意义[2-3]。

目前我国电子装备科研和生产任务十分繁重，项目研制周期短、产品种类多、原材料、配套件、半成品等数量不断增加，对物料出入库管理提出了越来越高的要求。传统的平库存储虽然可以适应日益增长的多品种小批量的生产模式需要，但物料中心库房管理员为完成物料出入库任务，需手动记录货架库位号，识别库位速度慢且难以进行断点控制。……
