Design And Implement Of Storage System Based On LMDS And RFID

Computer and communications technology has gradually penetrated into all sectors of society and led to changes in industry, warehousing industry is no exception. Rely on traditional manual mode of operation is no longer suited to the industry at this stage of competition, computer and communication technologies applied to the results of the latest storage industry, is a general trend.For storage systems, convenient, efficient, and stability has always been the goal. Popular in recent years the LMDS (Local Multipoint Distributed Service) and RFID (Radio Frequency Identification) technology is no doubt the achievement of this goal is a powerful tool. In this article, LMDS technology and RFID technology applied to the storage system, the following two techniques in this brief:1. LMDSLMDS is a wide wireless access technology. The technology uses high-capacity point-to-point microwave transmission to provide two-way voice, data and video services, and the realization of 2Mbit / s and even up to 155Mbit / s access speed for users with high reliability, referred to as "wireless fiber-optic "Technology [3].2. RFIDRFID is a non-contact automatic identification technology, radio frequency signal through the automatic recognition of the target audience and get the relevant data, there is no need to identify the work of human intervention can work in a variety of adverse circumstances. RFID technology can identify the high-speed movement of objects and at the same time to identify a number of labels, it's fast and convenient.RFID is mainly by the reader, microwave antenna and electronic tag is composed of three parts to the antenna for radio wave propagation. RFID data are usually small electronic tags. It is smart to read and write and the ability to encrypt communications. In practice, the electronic tags to identify objects to be attached to the surface, the electronic label has agreed to preserve the electronic data format. Do not have contact Reader, you can read and identify RFID tags in the preservation of electronic data, so as to achieve the purpose of automatic identification of objects. Reader through the antenna to launch some of the RF signal frequency, when the label into the magnetic field induced current generated in order to obtain energy; issued from its own label antenna coding and other related information, the reader to read and decoded related to the mainframe computer to deal with.In this paper, LMDS, RFID technology and storage systems to achieve enterprise storage solutions:1. LAN ConstructionTreasury for enterprises widely distributed the characteristics of mobility, this article through the use of microwave LMDS technology to build wireless local area network, to form a corporate headquarters for the Central Station to the Treasury for the terminal station, 5 km of the wireless network coverage. The company is headquartered database server installation, the installation of client revenue. LMDS wireless LAN through high-speed data, real-time transmission.2. Information CollectionIn the information collection of warehouse and ex-warehouse, used the RFID technology. For shipment into the RF labels affixed, and at the entrance to the Treasury set up a radio frequency reader to identify the shipment information in order to achieve a rapid and accurate warehouse and ex-warehouse.3. Storage system developmentAfter analysis of the composition and workflow system, used of UML (Unified Modeling Language) modeling system to design perfect as possible. And I proposed three-tier system architecture, that is, the user interface layer, business layer and data storage layer.User Interface Layer using Microsoft's C#.NET development front, the data storage layer using SQL Server development back-end database, business processing layer that is between the database and procedures through ADO.NET to communication, system architecture is C/S (Client / Server) mode.In this paper, the design of LMDS and RFID-based storage system with high-speed data acquisition and exchange functions, and used in DALIAN XINGSIN LOGISTICS INTERNATIONAL CO.,LTD, running in good condition.
