Intelligent Warehouse Management System Based on RFID Technolog

  • Warehousing has always played the most important role in the logistics system. With the rapid development of modern logistics, higher requirements have been put forward for warehouse operations such as ex warehouse, warehousing, shift, inventory and goods query. In RFID backscatter coupling mode, the frequency of electromagnetic wave reflected by a target is determined by the reflection cross section. The size of the reflection cross section is related to a series of parameters, such as the size, shape and material of the target, the wavelength and polarization direction of the electromagnetic wave, etc. Since the reflection performance of the target usually increases with the increase of frequency, the RFID backscatter coupling mode adopts UHF and UHF, and the distance between the transponder and the reader is greater than 1m. RFID Reader/writer, transponder (electronic tag) and antenna constitute a transceiver communication system. RFID technology warehouse management is aimed at warehouse arrival detection, warehousing, outbound, distribution, warehouse transfer, RFID technology application etc.

    Labels are reusable

    The data stored by RFID is electronic data, and the carrier for storing the data is an electronic chip. This chip has the function of writing repeatedly, which can be reused to reduce the one-time investment cost of the project.

    Miniaturization and diversification of Label Shapes

    Reading passive RFID tag is not limited by size and shape, and does not need to match the fixed size and printing quality of the paper for reading accuracy, which has greater advantages than the application of bar code technology in articles that need to combine the shape and size of the articles. In addition, the miniaturization of RFID tags can be more flexibly applied in the production line to control the production of products.

    System and data security of RFID Technology

    Transferring product data from the central computer to the workpiece will provide security for the system, avoid reading data directly from the system and greatly improve the security of the system, and use encryption methods to protect the data in the RFID RF tag, so as to ensure that the data will not be read.

    The significance of adopting RFID technology in intelligent warehouse management

    After years of development, RFID technology has made great progress both at home and abroad in terms of technology itself and application level. In particular, the application in the field of logistics warehousing is becoming one of the standard application technologies of modern efficient warehousing logistics due to its perfect standards, high maturity of technology and application, significant effect on the improvement of warehousing logistics management level, and the gradual reduction of RFID application cost. At the same time, RFID technology is also one of the key technologies in the development of modern Internet of things technology. In recent years, with the policy support and strong promotion, it is developing at a high speed. The Internet of things has made great progress in many fields including manufacturing, and has gradually become an inevitable choice to solve the information management problems in enterprise production, manufacturing, warehousing, logistics and other links.

    The project adopts RFID technology as the key technology in the warehouse management system, which can significantly improve the technical level of warehouse and logistics management, and the enterprise can obtain a good return on investment. For the present, the project is of exemplary significance, and in the future, it can effectively avoid and reduce repeated investment in enterprise informatization upgrading.

    At the same time, at this stage, RFID technology can help enterprises open up the data link between product market demand and supply side, and help enterprises achieve faster market response. Beijing clothing software 2022 has been updated (today / Business News). However, the product technology is not mature on the whole, and there is still a high error rate (the rate of RFID being misread is sometimes as high as 20%), and a large number of technical problems need to be solved in the integrated application. High security. Currently, the passive RFID system widely used does not have a very reliable security mechanism, so it is unable to keep the data confidential. RFID data is also vulnerable to attacks, mainly because the RFID chip itself and the chip can be easily used by hackers in the process of reading or writing data. Quick search and positioning of goods: when it is necessary to search for a certain goods, enter the relevant goods information in the handset, and scan the goods within a certain range. When the goods are scanned, the intelligent warehouse management system will send a prompt to facilitate the quick search of the goods.

    Physical layer:

    The physical layer includes warehouse, warehouse location, pallet, forklift, goods, field operation, etc. Field operations include goods warehousing, outbound, inventory, sorting, allocation, splitting, warehouse transfer, etc. RFID electronic tags are required to be installed on all effective warehouse locations (warehouses) and pallets in the warehouse to realize the fine management of pallets in a single warehouse location (warehouse).

    Acquisition and interaction layer:

    It includes various on-site data acquisition and user interaction equipment, including RFID handheld terminalRFID fixed reader, etc. It mainly provides user operation guidance, on-site data collection, data entry, etc. Provide real-time on-site data collection and interactive operation guidance for RFID intelligent warehouse management system.

    Data service layer:

    Manage the RFID equipment and related equipment in the system, collect, cache and filter the collected data, and collect and distribute the control instructions and related data. The data service layer runs on the system server in the form of system software services, providing data services for RFID data and related control instructions in the user application layer and data collection interaction layer.

    Enterprise application layer:

    The RFID intelligent warehouse management system provides the computer software user management interactive interface for the warehouse dispatching management center and the remote management center, and also provides report and data query services. The RFID intelligent warehouse management system center provides the planning, management control and data monitoring of warehouses and goods through the enterprise application layer.

    All the goods in the warehouse are transferred and stored in pallets. Through the electronization of pallets, the identity of each pallet can be identified, and the real-time tracking of storage and transfer positions can be realized. Combined with the electronic (digital) warehouse location management, it can provide the necessary data foundation for visual and intelligent warehouse management. Beijing clothing software 2022 has been updated (today / Business News). From the perspective of communication and energy sensing between electronic tags and readers, the system can generally be divided into two types, namely, inductivecoupling system and electromagnetic backscatter coupling system. Inductive coupling is realized by space high-frequency alternating magnetic field, which is based on the law of electromagnetic induction; Electromagnetic backscatter coupling, namely the radar principle model, reflects the electromagnetic wave emitted when it meets the target, and carries back the target information at the same time, which is based on the spatial propagation law of electromagnetic wave. Visual warehouse in / out management mainly covers warehouse in and warehouse out of goods (pallets). The intelligent warehouse management system shall be able to realize the visual management of warehouse real-time data in the management center. Truly realize the synchronization of real logistics and data flow.
