The Advantages of RFID in Logistics Industry Sales
For the logistics industry, companies and customers are most concerned about transportation speed and information accuracy, and RFID can just meet these conditions. In the application of the logistics industry, it has the following advantages:
· Read and write quickly. Barcodes can only be scanned one at a time, while RFID readers can identify and read several RFID tags at the same time.
· The reading and writing distance is long. In the case of being covered, RFID can penetrate non-metallic or non-transparent materials such as paper, wood and plastic, and can carry out penetrating communication. Barcode scanners can only read barcodes at close range and without objects blocking them.
· Reusable. The current barcode cannot be changed after printing, while the RFID tag can be repeatedly added, modified and deleted.
· The chip itself can store information. The capacity of one-dimensional barcode is 50 bytes, the maximum capacity of two-dimensional barcode can store 2~3000 characters, and the maximum capacity of RFID is several megabytes. With the development of memory carriers, the data capacity also has a trend of expanding. In the future, the amount of data that items need to carry will become larger and larger, and the demand for the expansion capacity of the label will also increase accordingly.
· Anti-pollution and durability. The carrier of traditional barcodes is paper, so it is susceptible to contamination, but RFID is highly resistant to substances such as water, oil, and chemicals. In addition, the barcode is attached to the plastic bag or the outer packaging carton, so it is particularly vulnerable to breakage; the RFID tag stores the data in the chip, so it can be protected from contamination.
System Design
---- System Design Principles
The sales system of the logistics industry is generally composed of multiple subordinate branches, chain headquarters, distribution centers and other institutions. The headquarters, branches, and distribution centers of the industry are often located in different geographical locations in a city, and their respective local area network servers need to be connected remotely through the Internet. The sales industry information management system adopts a distributed database structure: the first-level data server is located in the headquarters, the second-level data server is located in each branch, and all the servers constitute a distributed database system as a whole.
The block diagram of the commodity sales structure in the logistics industry is shown in Figure 1. Each sales store consists of a payment system, a purchase system, a wireless handheld terminal, and a management system. The four systems are connected by a computer network. The core equipment of the payment system, the purchase system, and the wireless handheld terminal are all RFID readers. The difference is that the payment system deletes commodity records from the database, the purchase system adds commodity records to the database, and the wireless handheld terminal is used for customers and staff. use.
---System Hardware Design
The reader is an indispensable hardware device for the RFID system, a tool for the system to exchange data with many mobile electronic tags, and a key link in the operation of the system. Its technical parameters have a decisive impact on the overall performance and reliability of the system. . Hardware design is the key to determine the performance of the reader, and its goal is to achieve the requirements of long reading distance, fast recognition rate and 100% recognition rate. The design of general RF reader is mainly composed of five parts: control module, RF transceiver module, antenna unit, communication interface module and power module. After research, it is found that some measures can be taken to improve the performance of the reader. According to the application characteristics of chain operation, it is more suitable to use a passive backscattering RFID reader. Structurally, it can be divided into 2 parts, namely the radio frequency front end and the digital baseband. The RF front-end part includes transmitting circuit, receiving circuit, circulator and antenna; the digital baseband includes DSP and FPGA chips. Among them, the transmitting circuit can be subdivided into a carrier circuit, a modulation circuit, and an amplifying circuit.
The Situation That RFID Faces in lLogistics Industry Sales
The biggest obstacle that restricts the development of RFID at present is the technical standard. There are 117 RFID protocol standards for data exchange in the world. There are too many agreements and too much, resulting in inconsistent terminology, which limits the perfection of the standard in practice. At present, there is no authoritative and unified standard that is globally complied with. Due to the many aspects involved in RFID, the work of formulating standards is very complicated. Related to the formulation of standards is the dispute over the frequency band used by RFID. To use RFID technology to achieve information exchange in the field of global logistics, there must be a global unified logistics RFID frequency band. Currently the United States uses 915MHz, Europe uses 805.8MHz, and Japan uses 960MHz.
Epilogue
In a word, RFID technology is one of the core competitiveness of logistics industry sales operation. Improving the operational efficiency of the commodity logistics system is a fundamental measure to improve the response speed of the entire system, an important cornerstone for the sustainable development of an enterprise, and a fundamental requirement for reducing the overall operating cost of the sales industry and improving competitiveness and profitability. The RFID technology is applied to the sales management of the logistics industry, the purchase system is installed in the commodity warehouse population, the payment system is installed at the outlet of the chain store, and the management system is connected through the computer network, thus forming a complete logistics industry sales system. This can effectively improve the management level and reduce operating costs.
