【摘要】：物资管理系统是提高企业运行效率、降低企业运行成本的重要措施,也是实现企业战略目标、增强企业竞争力的重要手段。本文针对作者的工作实际,设计了一款基于RFID技术的电力企业物资管理系统。RFID技术的使用可以降低仓库管理员对物资出入库管理的工作量,使得物资盘点和查找更加省时和简便,同时也能够有力保证仓储物资信息的准确性、提高物资存取速度。系统中将传统物资管理方式的招标采购、仓储管理、需求计划以及采购管理等内容整合到一个系统中,各个工作组通过网络共享数据库中的数据,减少彼此沟通的工作时间,这样所有的数据传输和信息传递都在系统中进行,不会出现信息不对称的问题,也可以有效提高工作效率。论文首先对RFID技术进行分析,介绍了RFID系统的组成、分类、相关通信协议,重点分析了电力物资管理系统中RFID系统的选型要求；分析了物资管理系统的数据库设计要求,对比了SQL SERVER、ORACLE、DB2与MYSQL几种数据库的优缺点,综合选定SQL SERVER为本系统使用的数据库；对比分析了B/S结构与C/S结构的优缺点,通过综合分析选定B/S结构模式。其次对市级电力公司物资管理系统的需求进行综合分析。分析了电力系统所需管理的物资分类,根据电力系统的物资分类特点进行物资管理分析；分析了电力系统物资管理的特点,结合物资管理在电力上的应用分析了现在化物资管理系统所需的功能,根据物资的流动方向确定了物资管理系统的流程,重点分析了系统各个组成模块以及功能需求；确定系统的设计原则,为系统设计划定标准。最后对物资管理系统的设计与实现进行描述。按照MVC的架构模式,本系统设计分为表现层、业务逻辑层和数据支撑层三部分。其中业务逻辑层又分为需求计划子系统模块、招标管理子系统模块、采购管理子系统模块、仓储管理子系统模块、物流管理子系统模块和系统管理部分。论文重点分析了仓储管理子系统设计和招标管理子系统设计,这两部分内容是本设计的创新点。仓储管理子系统将RFID技术的应用与传统的基于货位的管理方式相结合,即满足了电力企业的行业应用,又降低了仓储管理的成本,节约管理时间。招标管理子系统是目前物资管理的重点发展方向,采用网络招标的方式能够节约招标时间和成本,同时又能扩大招标范围,采购到物美价廉的物资。最后对数据库部分的设计实现进行分析,明确了数据库的设计原则、E-R图设计以及数据库的双机热备份部署和数据的异步同步。
[Abstract]:Material management system is an important measure to improve the operation efficiency and reduce the operating cost of the enterprise. It is also an important means to realize the strategic goal of the enterprise and enhance the competitiveness of the enterprise. In this paper, according to the actual work of the author, we design a power enterprise material management system based on RFID technology. The use of RFID technology can reduce the workload of the warehouse administrator to manage the material in and out of the warehouse. It makes inventory and search more time saving and simple, at the same time, it can ensure the accuracy of storage material information and improve the speed of material storage and storage. In the system, the traditional material management methods, such as bidding and purchasing, warehousing management, demand planning and purchasing management, are integrated into one system. The working groups share the data in the database through the network to reduce the working time of communicating with each other. In this way, all data transmission and information transmission are carried out in the system, without the problem of information asymmetry, and the work efficiency can be improved effectively. First of all, the paper analyzes the RFID technology, introduces the composition, classification, related communication protocols of the RFID system, analyzes the selection requirements of the RFID system in the power material management system, and analyzes the database design requirements of the material management system. The advantages and disadvantages of several databases of SQL SERVER,ORACLE,DB2 and MYSQL are compared and SQL SERVER is selected as the database of the system, and the advantages and disadvantages of B / S structure and C / S structure are analyzed, and the B / S structure pattern is selected by comprehensive analysis. Secondly, the demand of material management system of municipal power company is analyzed comprehensively. This paper analyzes the material classification needed for power system management, analyzes the material management according to the characteristics of power system material classification, and analyzes the characteristics of power system material management. Combined with the application of material management in electric power, this paper analyzes the functions needed by the current material management system, determines the flow of the material management system according to the flow direction of the material, and emphatically analyzes each component module and functional requirements of the system. Determine the design principles of the system and define the standard for the system design. Finally, the design and implementation of material management system are described. According to the architecture of MVC, the system is divided into three parts: presentation layer, business logic layer and data support layer. The business logic layer is divided into demand planning subsystem module, bidding management subsystem module, procurement management subsystem module, warehouse management subsystem module, logistics management subsystem module and system management module. This paper focuses on the design of warehouse management subsystem and tender management subsystem, which are the innovation points of this design. The warehouse management subsystem combines the application of RFID technology with the traditional management method based on cargo location, which not only satisfies the industry application of electric power enterprises, but also reduces the cost of storage management and saves management time. The tender management subsystem is the key development direction of material management at present. The network bidding method can save the bidding time and cost, at the same time, it can expand the bidding scope and purchase the goods with good quality and cheap price. Finally, the design and implementation of the database are analyzed, and the design principle of the database is clarified, including the design of the E-R diagram, the deployment of the hot backup of the database and the asynchronous synchronization of the data.
