Rfid Technology System Improves Warehouse Management Ability

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, transfer, inventory, goods query, etc. Product advantages: labor saving, fast card reading, accurate data, chip encryption, brand protection, intelligent and professional, function, system stability, tracking and traceability, and prevention of fleeing goods. The Internet of things has been identified as one of the strategic emerging industries. The introduction of the “development plan of the Internet of things” undoubtedly brings a strong east wind to the developing Internet of things. As a key technology for the development of the Internet of things, RFID technology will expand its application market with the development of the Internet of things. Facing the fierce competition in the industry, manufacturers have tried their best to design and produce a large number of PDA products with different models and performances. From the demand side, it is another situation. In the face of a wide range of brands and product models, the choice of UHF handheld reader is not an easy thing.

The application of radio frequency identification (RFID) can fundamentally solve the above problems. Based on radio frequency identification (RFID) technology, Hangzhou Dongshi technology has developed an RFID intelligent warehouse management system according to the actual situation and needs of warehouse management.

RFID, the abbreviation of radio frequency identification, is a non-contact automatic identification technology. RFID can be traced back to the Second World War (about 1940), when its main function was to distinguish the enemy from the British aircraft. In recent years, with the development of large-scale integrated circuit, network communication, information security and other technologies, as well as the promotion of Wal Mart, the world’s number one retailer, RFID has been rapidly applied to smart grid, transportation, logistics industry, medical health, fine agriculture and animal husbandry, finance and service industry, industry and automatic control, smart home, environment and safety detection, public security, national defense, smart city and other industries and fields. RFID is to automatically identify the target object and obtain relevant data through RF signals. It is mainly composed of RFID tags, readers (Readers), and antennas (antennas). Tags are composed of coupling elements (also known as antennas) and chips. Each tag has an electronic code (EPC), and the chip can store specific serial numbers and other information. The reader is the bridge between the tag and the software system. On the one hand, it reads the tag information, on the other hand, it communicates the reading results with the software system. The antenna exists in the tag and reader, and is responsible for the data transmission task from the tag chip to the reader and then to the software system.

RFID technology is divided into low frequency, high frequency, ultra-high frequency, active, etc. RFID technology has the characteristics of non-contact, fast scanning, high identification efficiency, not easy to be damaged, suitable for harsh environment, convenient operation, fast reading and writing speed, large amount of information storage, multi-purpose one card, anti-collision, good security encryption performance, reusability, tracking and positioning, etc.

Intelligent warehouse management lies in the allocation of storage resources, accurate warehouse operation control, and the transparent transmission of real-time and effective storage data flow. The core content should include: visual warehousing management. When purchasing and leaving the warehouse, all items of different categories can be scanned at one time through the scanner, and the anti-theft function can be removed when the sales order is generated at the cashier. In this way, the alarm will not sound when the customer leaves with his shopping. When the customer pays the bill, the cashier will write the date of sale into the label, so that the items purchased by the customer are also guaranteed and promised accordingly. Book management, rental product management, and putting electronic labels in books can easily receive book information. When sorting books, there is no need to move books, which can improve work efficiency and avoid work errors. Automatically collect the data of various operation links such as inventory, so that the speed and accuracy of data in various links of warehouse management are more intelligent, which is convenient for enterprises to manage stored goods.

By quoting RFID technology, we can improve the efficiency of warehouse management and provide the accuracy of WMS system data. The main objectives are as follows

Reduce human operation leakage, improve management level and reduce potential safety hazards;

Data collection is real-time, and items and records are consistent in time;

Reliable and stable data acquisition and accurate data;

The statements are sorted and summarized manually and then completed by computer;

Improve the efficiency of data management, register the detailed accounts of various safety tools and instruments in time, so as to achieve the consistency of accounts, materials and cards;

The system is flexible and has expansion function;

The system is practical and easy to operate, aiming at users with different levels of professional quality.

At present, it is widely used in international container transportation, which not only helps to improve the efficiency of cargo operation under the background of globalization, but also improves the security to a certain extent. In RFID backscattering 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. Desktop RFID Reader writer, transponder (electronic tag) and antenna constitute a transceiver communication system. In this process, the use of hand-held PDA can achieve efficient inventory of goods and more accurate data-based management and control. Next is the packaging container stage. Single products are packed in dozens and boxes. RFID is installed on the surface of cartons or other outer containers, which can greatly improve the visibility of packaging.
