【摘要】：随着近年来物流行业的迅速发展,仓储越来越受到企业和客户的关注,仓储的管理水平直接关系到企业发货速度和货物的周转速度,同时货物在仓库中储存不产生附加价值,还会占用资金,而储存时间过长还会影响货物的质量,因此如何实现对仓库的精益化管理成为当前研究的一个热点。而自动化立体仓库作为当前仓库的代表,它综合了现代化物流技术、先进的计算机应用技术、科学的管理技术,更是成为研究的重点,本文以某物流综合实验室某型号的立体仓库为研究背景,针对当前立体仓库的信息采集、货位分配、出入库状况进行分析,结合当前信息采集技术以及所拥有的条件,设计并开发了基于RFID的立体仓库管理系统。本文首先对某型号的立体仓库进行简要的描述,并针对条码信息采集过程中出现识别速度慢、条码打印错位以及时间过长条码卷曲脱落等问题,结合实际情况及现有设备,对条码信息采集与RFID信息采集的优劣势进行分析对比,确定以RFID技术取代现有的条码技术,实现信息的自动识别和采集。然后在文中对RFID的相关理论进行简要介绍,并就RFID部件选型、RFID与系统的连接进行了研究。其次针对现有立体仓库货物入库时手动分配货位效率低、速度慢的问题进行了分析、研究,结合货位分配原则、策略,在前人提出的螺旋货位分配的基础上,提出了改进的螺旋货位分配法,以堆垛机到目标货位的时间与所在货位重心离地面的高度的乘积的最小值为目标构建模型,实现货位的自动分配,并将之与实际系统相结合,进行编程和应用。最后以现有立体仓库系统为原型,设计了基于RFID的立体仓库管理系统。该系统综合分析了系统需求和所要实现的功能,将系统划分登录、入库、在库、出库、系统管理、报表管理等模块,运用SQL Server 2012进行数据库设计,并用VS2015中的C#语言对系统的进行编程,实现对立体仓库货物的入库信息自动采集、货位分配、在库盘点和预警、报表管理等,增强立体仓库信息化管理水平,提高立体仓库入库效率,减少操作流程和操作人员的工作量。
[Abstract]:With the rapid development of logistics industry in recent years, warehousing has attracted more and more attention from enterprises and customers. The management level of warehousing is directly related to the speed of shipping and the turnover of goods. At the same time, the storage of goods in the warehouse does not produce additional value, but also takes up funds, and the long storage time will affect the quality of the goods, as a result, the storage time will affect the quality of the goods, so the storage time will affect the quality of the goods. How to realize the lean management of the warehouse has become a hot spot of research. As the representative of the current warehouse, the automated warehouse integrated modern logistics technology, advanced computer application technology and scientific management technology, and it has become the focus of research. This paper is based on a three-dimensional warehouse of a certain type of Logistics comprehensive laboratory. The research background, in view of the information collection of the warehouse, the distribution of cargo space, the status of the outgoing storage, the RFID based warehouse management system is designed and developed in the light of the current information collection technology and the conditions. This paper first briefly describes a model of the warehouse, and aims at the process of barcode information collection. In the case of slow recognition speed, misprint of bar code printing and long bar code curl falling off, combined with the actual situation and existing equipment, the advantages and disadvantages of the bar code information collection and RFID information collection are analyzed and compared, and RFID technology is used to replace the existing bar code technology to realize the automatic identification and acquisition of the information. Then the RFI is used in the paper. The related theory of D is briefly introduced, and the connection between RFID component selection and the system is studied. Secondly, the problem of manual distribution of freight bit efficiency and slow speed is analyzed in order to solve the problem of low efficiency and slow speed when the goods are stored in the existing warehouse. The improved method of spiral location allocation is used to build the model for the minimum value of the time of the stacker to the target cargo position and the height of the height of the center of gravity of the location of the location of the location of the cargo. The automatic distribution of the goods is realized, and it is programmed and applied in combination with the actual system. Finally, the existing stereoscopic warehouse system is used as the prototype and the RFID is designed. The system comprehensively analyzes the system requirements and the functions to be realized, divides the system into the login, the library, the library, the library, the system management, the report management and so on. It uses SQL Server 2012 to design the database, and uses the C# language in VS2015 to program the system to realize the warehousing of the three-dimensional warehouse goods. Automatic information collection, distribution of goods and goods, inventory and warning, report management, and so on, enhance the level of information management of the three-dimensional warehouse, improve the efficiency of the warehouse and reduce the operation flow and the workload of the operators.
