1. Project background
In recent years, the domestic jewellery industry has developed rapidly. China has become an important global jewellery industry gathering place, and has gradually formed a jewellery industry chain integrating jewellery raw material procurement, processing, trading, design, appraisal, information exchange, logistics and exhibition. The jewelry industry has unique industry characteristics, such as expensive materials and products, small production scale, and special management methods. As operating costs continue to rise, the international economic situation deteriorates, and competition becomes more intense, some industries have gradually realized the importance of logistics management.
In traditional jewelry logistics management, barcode technology is usually used. Although this technology can improve the efficiency of logistics management to a certain extent, it still cannot meet the needs of the modern jewelry industry. The problems of low storage information volume of bar codes, non-additional information, easy damage, and high requirements for reading positions have gradually emerged. However, radio frequency identification technology (RFID) uses wireless radio frequency to carry out non-contact two-way data communication to identify targets. Compared with traditional bar code identification methods, RFID technology does not require direct contact, optical visibility, and manual intervention to complete information. Input and processing, and the operation is convenient and fast, which can solve the problem of barcode.
2. Technical introduction
RFID radio frequency identification technology uses the principle of radar reflection to send a microwave inquiry signal to the electronic tag through the antenna. The electronic tag is activated by the microwave energy of the reader, and responds after receiving the microwave signal and sends out an echo signal with the tag data information. The basic feature of radio frequency identification technology is to use radio technology to identify stationary or moving objects, to determine the identity of the object to be identified, and to extract the characteristic information (or identification information) of the object to be identified. For more products and solutions, please visit the company’s official website www.fuwit.com or call 400-0581-580
The characteristic information of the object to be identified collected through the radio frequency identification system is usually processed by middle software first, or the collected identification information is directly processed through computer information processing technology (such as database technology, etc.) and computer network technology (Intranet & Internet). Technology) Realize the integration, sharing, and long-distance transmission of information to directly serve related business application systems, such as RFID jewelry management systems.
3. The overall scheme design of the system
3.1 System design ideas
In order to achieve precise management of jewelry, it is necessary to locate a single jewelry. In Shenzhen Quanshunhong RFID smart jewelry management system, RFID electronic tags have a unique ID number. Therefore, after the electronic tags are one-to-one corresponding to the individual jewelry, the electronic tags To achieve the goal of precise management of individual jewelry. At the same time, RFID equipment has the characteristics of simultaneous reading of multiple tags, so through the construction of RFID jewelry management system, fast and accurate inventory of goods can be realized, and efficient management of jewelry assets can be realized.
RFID jewelry management system penetrates deeply into each key node of jewelry assets from warehousing, sales, inventory, and sales, and combines computer and network technology to create an RFID smart jewelry management system to realize the informatization, accuracy and efficiency of jewelry assets manage. The basic network diagram is as follows:
3.2 System business process plan
The construction of the RFID smart jewelry management system integrates RFID technology into all aspects of jewelry management from storage to completion of sales. Enterprises can deploy RFID systems at key nodes according to their own business characteristics.
This article focuses on the application of RFID technology in warehouse entry and exit, inventory and search.
3.2.1 Card Issuing System
Issuing a card is to give each jewelry a unique “identity ID” and establish basic data information. After the jewelry is processed, an electronic tag is installed for each jewelry. The packaging of the electronic tag is specially designed for jewelry products. It can be easily and simply hung on the jewelry without affecting the appearance of the jewelry, and at the same time, it can only represent a jewelry. In this link, a card issuer is used to write the electronic product code (EPC) of the jewelry and other data information into the corresponding electronic tag, and upload it to the application center server to realize the binding of the RFID electronic tag and the jewelry asset.
3.2.2 Inbound and outbound management
After the basic information is initialized, the jewels are neatly arranged and placed in the display tray, and stored in a safe or other area for storage.
Before entering the warehouse, place the exhibits in a radio frequency field composed of RFID readers and RFID antennas. The RFID readers will collect all the jewelry tag information in the display tray at one time to complete the entry of the warehousing information.
3.2.3 Inventory
Under each display counter, RFID equipment will be installed concealedly, including RFID antennas and RFID fixed readers. The number of antennas is selected according to the size of the jewelry display area. Up to four antennas are supported, which can realize the entire jewelry display area. There is no dead angle in the range to read.
When you need to carry out the inventory business, you only need to start the inventory work on the control computer, and the RFID reader on the counter will start to read the card, scan all the jewelry information on the counter and make statistics to complete the inventory work.
3.2.4 Jewelry search and location
The RFID reading system installed on the counter can also be used to quickly locate and locate a single jewelry or a series of jewelry. Just enter the jewelry number in the background system, and the system will start reading according to the entered jewelry number, quickly find the location of the jewelry with the specified number, and quickly locate it.
4. Selection of core equipment
The core of the RFID smart jewelry management system is the real-time communication between RFID and all jewelry binding tags to realize the intelligent management of jewelry. Therefore, the core equipment is the multi-tag processing capability and the overall reliability and stability of the system.
4.1 RFID reader
ThingMagic M6 UHF reader has a high-speed reading capability of 750 tags/sec, which meets the requirements of multi-tag processing capabilities in jewelry management applications. At the same time, ThingMagic M6 is a four-channel reader that can connect up to 4 antennas at the same time. , The coverage is wider, and the real-time monitoring and tracking of the maximum number of tags can be realized at a lower cost. ThingMagic M6 has super anti-interference ability and can adapt to various harsh industrial environments. The dual optimization of good power consumption and heat dissipation can ensure long-term uninterrupted and stable operation of the equipment, which is suitable for the requirements of the jewelry management system for equipment stability.
4.2 RFID antenna
In the application of this system, in order to ensure the precise search and positioning of jewelry, the RFID reading range should be controlled within a single tray as much as possible, and the labels in other trays cannot be misread. The currently widely used far-field antenna has a long reading distance and a wide range, and cannot be used in this system.
A1030 is a near-field antenna with excellent performance. It has the characteristics of wide area, thin thickness, light weight, and good field shape. It is easy to install in standard display cabinets. Its gain of -15dBi retains the high power of ThingMagic reader equipment. Sensitivity, and the RF field pattern is condensed, so that the problem of multi-tag short-distance reading can be solved. With ThingMagic UHF RFID reading and writing equipment, the effect is excellent, and it can be easily applied to jewelry, retail POS, library, medical and health care In RFID occasions such as ultra-high frequency bands.
