1.1 Project background
In China, the clothing industry in major shopping malls, commercial buildings, shop clothes, online stores, inventory, etc. sells countless garments every day. Such a large number of inbound and outbound management is now done manually. The accuracy, timeliness and real-time query of the goods in and out of the warehouse cannot meet the management requirements of the enterprise. Based on the above circumstances, a set of scientific and effective measures are designed and implemented. With the commodity inventory management system, improving the management level of the enterprise has become the focus of attention of the management.
1.2 Demand analysis
1.2.1 Project demand analysis
The basic business process of brand apparel is nothing more than production, warehousing, logistics and sales. Brand apparel currently uses traditional barcode recognition technology to process relevant information in warehousing inventory, logistics management, and sales management. However, as mentioned above, because the barcode technology has its inherent limitations, it is necessary to introduce more advanced technical solutions and equipment to improve the management efficiency of the enterprise.
Once the RFID tag is added to the garment, it is no longer necessary to open the box for inspection or random inspection when entering and leaving the warehouse, and the goods can speed up the batch circulation. According to the current technology, using RFID scanners, the reading rate of a box of 100 garments within 50-100CM is 100%. As a result, in the whole box of goods, how many kinds of garments, different colors and sizes The distribution is clear. Boxes of goods are scanned at one time and passed quickly. There is no need to review item by item like a barcode. This greatly improves the efficiency of goods in and out of the warehouse and breaks the bottleneck of inefficiency in the supply chain.
This project mainly uses RFID technology to achieve high efficiency of logistics operations and single-product tracking management of goods. At the same time, RFID technology is integrated into the warehouse management system to achieve the following goals:
(1) Ensure the strict and accurate quantity of internal logistics and external logistics of the enterprise;
(2) Real-time inventory query and display;
(3) Monitor and manage the overall operation status of commodity logistics;

The unique identification methods and technical characteristics of RFID technology have brought huge benefits to retailers, suppliers and customers. In an efficient way, it enables the supply chain system to more easily and automatically track the dynamics of goods, so that the goods can be real Automated management.
In addition, RFID also provides the retail industry with advanced and convenient data collection methods, convenient customer transactions, efficient operation methods, fast and insightful decision-making methods, and other benefits that barcode technology cannot replace.
1.3 Advantages of RFID technology application
Because RFID uses the principle of radio frequency identification, it can work in a variety of harsh working environments, can penetrate certain obstacles, and has good penetration; it can also identify goods in motion, and can be identified in batches; RFID tags can also repeatedly erase and write data, and the tags can be reused. The information in the RFID tag is quickly uploaded to the enterprise information system for comprehensive management, which can avoid errors that may occur in manual operations.
RFID is different from barcode. Each piece of clothing (RFID tag) has a unique number, and its purpose is as follows:
(1) Don’t worry about repeating the order when taking inventory
(2) Single item can be tracked
(3) Valid e-vouchers can be generated for exit/entry.
The use of RFID technology to reduce inventory, fast delivery, timely replenishment, mixed packing, automatic confirmation, and fast point handover methods can be effectively used in goods fairs, production monitoring, warehouse distribution and supply chain management, as well as store sales and special sales links. Solve the operational and financial pressures of the company adopting the technology.
1.4 RFID service management system construction plan
1.4.1 RFID working principle
At present, various large-scale clothing companies in China are gradually building RFID systems, which can use RFID technology to identify multiple tags at the same time, with fast recognition speed, long recognition distance, repeatable tags, etc., to efficiently manage clothing, and form an effective clothing industry supply. chain.
The RFID system consists of the following parts:
UHF RFID technology
UHF RFID radio frequency identification is a non-contact automatic identification technology, which automatically recognizes the target object and obtains relevant data through radio frequency signals. The identification work does not require manual intervention and can work in various harsh environments. Compared with barcode technology, UHF RFID technology has the following characteristics:
? Non-visual recognition
RFID electronic tags can exchange data with the reader through radio electromagnetic waves, so they can be read normally without opening the outer packaging.
? Multi-target recognition
Multiple UHF RFID electronic tags can be quickly identified at the same time, so they can be applied to the management of product in and out links to improve the efficiency of logistics operations.
? Fast recognition speed
The recognition speed of UHF RFID electronic tags is much higher than that of barcodes. The usual readers can read 100 electronic tags per second. This feature is conducive to improving logistics efficiency and rapid inspection.

1.4.6 Work Flow
1.4.6.1 Label selection
This project is different from other projects and belongs to a specific project, because the object of management is not only ready-to-wear, but also comprehensive object management such as leather shoes, belts, and ties. Therefore, the choice of labels cannot be simply set as one type. Therefore. In order to achieve a higher single product reading effect, the following types of labels are recommended.
The first category is the garment label. The label will be optimized and customized according to the material of the garment such as cotton, fiber, wool, etc. At the same time, the size of the label will be set according to the size of the garment tag. The ideal result is to design a label, but It does not rule out the possibility of two labels.
The second category is leather shoes, belts, and leather bags. In addition to leather, the material of this category of products also contains metal. The metal impact caused by mixing must be considered. The label should be optimized and customized, and it will be based on the size of the tag. , Set the size of the label, the most ideal result is also designed into one category, but it does not rule out that there will be two kinds of label design generation. like:
There is a tag, and the RFID function is realized after packaging:
Separate RFID tag and label
There are tags + stickers to realize the RFID function:
1.4.6.2 Label making
Label production is mainly composed of tag machines, card issuing machines, and card issuing software.
1.4.6.3 Inbound and outbound management
? Warehouse management
In the warehouse, goods are placed on containers according to their type, such as style or brand. Bar codes are affixed to the shelves for easy identification. In daily life, employees will hold RFi Qifeng to read the goods labels and shelf barcodes, and associate the goods with the stored shelves. The handsets are embedded with barcode scanners, and the containers use barcodes instead of RFID tags. In order to avoid obtaining data at the same time The ID number of a container.
? Outbound management
After using the RFID application, the manufacturer’s label is affixed to the clothing item to be sent and verified before delivery, and then an advance shipment notice is issued to the retailer. After the packaged clothing arrives at the distribution center, it will be placed on the conveyor belt. During the transmission process, these labeled packaged clothing will be read by the channel RFID reader. The data after reading is sent to the system, and the software will confirm the ID information. In the event of an incorrect or missing system, a warning will be issued to remind employees to check the clothing goods in the box.After the clothing is repackaged, it is shipped to the clothing store. Before being loaded on the truck, the staff will read the ID number on the tag in the RFID channel according to the packing list, and finally send the advance shipping notice to the clothing store.
1.4.6.4 Inventory management
Both manufacturers and clothing stores can use RFID readers to carry out warehouse inventory. Customers can automatically analyze the tags read by the readers to know the actual clothing of a certain style, color, and model. Quantity, so as to ensure the balance of inventory, and timely replenishment, to avoid the phenomenon of out of stock or broken codes of a certain clothing in the clothing store, and to ensure the normal needs of customers.
