With the rapid development and application of RFID technology in various industries, the field of logistics supply chain will bring great changes, which will greatly improve the efficiency and transparency of supply chain management. By adopting the visual template design method, the OPRFID multi-user mall system home page, navigation, floor, advertising space, special topics, merchant stores and mobile terminals can be personalized configured according to the needs of their own websites, providing multi-mode clients and customized services for each tenant, Greatly improve the integrated operation efficiency of the core industrial chain. The multi tenancy OPRFID platform supports the member management function and improves the customer service experience. The modern warehouse reserve not only completes the simple batch processing of goods in and out, but also makes clear database records of the types, quantities, production attributes, stacking positions and other information of goods in the warehouse. So as to obtain accurate goods data and supply chain information at all stages of the logistics link.
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 tags 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.
RFID handheld terminal is a kind of wireless portable equipment that integrates RFID radio frequency technology and data terminal. It has the characteristics of large capacity storage, long service time, multiple communication and expansion interfaces, hardware modules can be selected according to different needs, and software can be customized according to user needs. It is widely used in warehousing management, such as warehousing and inventory, material shelving, inventory and point warehousing, material outbound, retrieval and query. The security problems faced by RFID technology are mainly manifested in the illegal reading and malicious tampering of RFID electronic tag information. Technical standards are not unified. At present, RFID technology has not formed a unified standard, and a variety of standards coexist in the market, which leads to the incompatibility of RFID tags of different enterprise products, and then causes the confusion of the application of RFID technology to a certain extent. The development status and Prospect of RFID technology. With the continuous reduction of the cost of RFID equipment, the gradual unification of standards, the in-depth and wide application of digital information technology in various industries, and the expansion of scale application industries, RFID technology will have a broader development prospect, its potential value will be brought into play, and the RFID technology industry will gradually grow and mature. With the rapid development and application of RFID technology in various industries, the field of logistics supply chain will bring great changes, which will greatly improve the efficiency and transparency of supply chain management.
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 terminal, RFID 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.
However, for most small and medium-sized warehouses, PDAs with complete functions and easy operation are generally preferred. There are obvious differences between the two. RFID backscattering coupling modes. The frequency of an object's reflected electromagnetic wave is determined by the reflected 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. Reader / writer, transponder (electronic tag) and antenna constitute a transceiver communication system. 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.
