1. Project background
At present, China’s jewelry industry is in a stage of rapid growth. Jewelry companies must not only seize historic opportunities, but also prepare for the reshuffle stage of the industry. In such a wave, how can companies ensure the quality of their products? , Prompting the efficient management of products is particularly critical. Throughout the management of the entire jewelry industry, most of the problems existed in the counter inventory of monopoly points. However, the current jewelry inventory work is basically completed by manual operation. However, the actual situation of jewelry products is small in size and large in quantity. Inventory by the sales staff of the company resulted in a huge time-consuming inventory work. Data shows that it takes an average of five hours for an ordinary jewelry to take an inventory of the products in the store. The problem of inventory efficiency has caused each jewelry store to be unable to inventory products on a daily or weekly basis. At the same time, because jewelry is mostly a high-value product, its various indicators and parameters are cumbersome and professional, and the staff is easy to lose when it is complicated, and the shopping guide cannot respond quickly. At the counter with a large number of jewelry, the work of the shopping guide will be affected. It will cause a lot of pressure and easily cause the theft of valuables. This kind of management sales method that completely relies on human experience and ability has largely restricted the business expansion and customer experience of the enterprise.
Jewelry companies urgently need effective management methods to improve the level of information management. Quan Shunhong’s RFID smart jewelry management system can quickly, accurately, easily and practically complete the inventory of goods, help companies understand the sales of various types of products in a timely manner, and complete the data analysis accepted by the company’s management on various product markets, and It can monitor the status of jewelry in real time to minimize the possibility of jewelry loss.
existRFIDToday, with the rapid development and application of technology, RFID electronic and information management of jewelry is an important means to strengthen inventory management, sales management, and improve management efficiency. The electronic and informatization of jewelry management will greatly improve the work efficiency of jewelry enterprises (inventory, inventory, and storage), reduce theft rate, and enhance corporate image and product added value. RFID will realize the wisdom of jewelry management.
2. Introduction to RFID UHF System
The UHF RFID system uses the principle of radar reflection. The Quanshunhong RFID reader sends 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 the data message with the tag. Echo signal. 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.
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 the RFID smart jewelry management system.
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 the Quanshunhong RFID smart jewelry management system, the RFID electronic tag has a unique ID number. Therefore, after the electronic tag is one-to-one corresponding to the individual jewelry, the electronic tag is Identify and achieve the goal of precise management of individual jewelry. At the same time, RFID equipment has the feature of simultaneous reading of multiple tags. Therefore, through the construction of Quanshunhong RFID smart jewelry management system, fast and accurate inventory of goods can be realized, and efficient management of jewelry assets can be realized.
Quan Shunhong’s RFID smart jewelry management system penetrates deeply into the key nodes of jewelry assets from storage, sales, inventory, and sales, and combines computer and network technology to create an RFID smart jewelry management system to realize the informatization and accuracy of jewelry assets. And efficient management. The basic network diagram is as follows:
Quanshunhong is the first company to introduce UHF RFID technology into smart jewelry management, attaching RFID tags to valuable jewelry products, and using automatic identification equipment to monitor, control and track labeled jewelry to achieve rapid inventory, real-time tracking and sales management intelligence . In this way, the all-round tracking and recording of the entry and exit of jewelry products and the sales process are carried out, and the cumbersome and inefficient manual management and bar code scanning mode are replaced with new methods of automation and accuracy and efficiency.
3.2 System business process plan
The construction of Quan Shunhong’s RFID smart jewelry management system integrates RFID technology into all aspects of jewelry management from storage to completion of sales.
From the issuance of the card at the time of initial warehousing, the launch of the card after the card issuance, the safety monitoring during sales, to the inventory check of the goods, to the final settlement and supply replenishment, RFID technology will string together the entire business chain to complete the jewelry asset management process. Accurate, efficient, information management and tracking.
3.3. Card Issuing System
After the jewelry is purchased, 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.
3.4 Safety monitoring system
This subsystem provides monitoring and early warning for the safety of jewelry in sale.
After the jewelry is issued, it can be displayed on the counter. After all the jewelry is placed in the display area, the staff will start the “commodity on the shelf” process at the management computer.
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. After the goods put on the shelf process is started, the reader starts to work, scans and uploads the information of each counter product to the computer, the staff can check the information, if there is no error, then “complete the shelf”, after that, the reader starts to enter the jewelry safety monitoring state . The staff can flexibly configure the allowable warning time through the software according to the actual situation of the sales work. During the warning time, the system will not detect the jewelry label but will not give an alarm. Once the warning time is exceeded, the system will activate the alarm device. Under safe conditions, the RFID reader can read the information of each jewelry electronic tag on the counter through the antenna. Once there is an accident, the reader cannot read the information of a certain tag within a certain period of time, and it will pass through the system The alarm device gives the staff an alarm.
The installation diagram of the subsystem equipment is as follows:
At the same time, in order to cope with the situation that the jewelry cannot be returned to the counter within the warning time due to long-term consultation or viewing by some customers, the staff can use the handheld device to read the electronic jewelry of the jewelry when the system alarm time is approaching or the system has been alarmed. Tag, and choose to extend the warning time on the handheld device software, the system will suspend the alarm and start a new warning time.
Such a system function setting will monitor the safety of jewellery to the greatest extent and at the same time affect the normal development of sales to the minimum.
3.5 Smart Sales System
RFID equipment monitors all the jewelry on the counter in real time. For some important and rare treasures, LED displays can be deployed in the accessories of the counter. When the jewelry is displayed to the customer, the system screen will immediately display the relevant detailed attributes of the jewelry “style, origin” , Designer, weight, material, purity, grade, etc., on the one hand, it has invisibly improved the credibility and brand image of the jewelry brand. On the other hand, it helps the sales staff to spare more energy to provide better value-added services and improve Customer experience and sales promotion.
At the same time, RFID equipment monitors all the goods in the counter in real time, and can record in detail the number of times each piece of jewelry is displayed to customers. Through in-depth mining of these data, the company management center regularly captures customer consumption behavior, tastes, and preferences. The backend provides a big data foundation so that the management can make better market decisions.
3.6 Quick inventory system
The layout of the RFID equipment of the sales safety monitoring system, while completing the jewelry safety monitoring and early warning, provides the possibility for real-time, fast and accurate inventory; every counter has RFID equipment, and the RFID equipment can read every jewel on the entire counter Therefore, when counting, you only need to perform the counting operation through the management software, and the RFID readers of each counter can quickly and accurately upload the real-time jewelry quantity and type of the counter to the management computer for summary, so as to realize the entire counter Mastery of all jewelry information.
For jewelry that is not placed on the counter, the information of the jewelry can be read through the RFID handheld device and uploaded to the management computer through the network. The computer management software integrates the jewelry data information on the counter and the data information fed back by the handheld device to complete the process. The statistics of the jewelry inventory of the entire store can quickly and accurately complete the inventory operation.
After the inventory, the system can compare the summarized data with the initially entered data and the sales and outbound information. Once the data is wrong, it can be fed back in time and accurate to the wrong counter.
3.7 Settlement and supply replenishment system
The settlement center in the store will be equipped with an integrated reader to cooperate with the staff to quickly complete the real-time update of pricing and product information in the database.
When the customer purchases and settles the jewelry product, the staff will read the jewelry tag on the integrated reader configured at the cash register. The computer at the checkout counter will display the information related to the product and prompt the customer to spend the amount. After the transaction, the staff confirms the completion of the sale on the computer, and the central server marks the product as sold in the database. At the same time, the counter RFID device will no longer maintain the monitoring of the device.
When jewellery at the counter needs to be supplemented after being sold, it is only necessary to replenish the source through the management computer after the jewelry is placed. The RFID equipment at each counter will automatically scan the counter jewelry information and display the newly added jewelry information on the management computer , The staff confirms that they are correct and click “Add” to complete the supply replenishment operation, and the new jewelry will enter the counter safety monitoring list.
