Chapter 1 Introduction
1.1 Project background
Competition in the apparel industry is becoming more and more fierce. To be invincible in the market competition, apparel industry companies must continuously improve production efficiency and shorten the capital turnover time. At this time, the advanced management methods and management models of information technology have changed. Very important. At present, most of the clothing industry’s informatization construction is relatively backward, resulting in poor information feedback. When a problem occurs, it cannot be discovered and dealt with in time, which leads to a lack of work in many links. At the same time, the situation of product sales cannot be grasped in time, resulting in the out-of-stock of the best-selling products and the under-selling of the products, which also reduces the profit. For apparel brands, branded apparel is counterfeited, sold on the Internet or sold in chaos as soon as it goes on the market, causing huge direct economic losses to the company and damaging the brand image.
UHF RFID technology uses wireless radio frequency for non-contact two-way communication to exchange data to achieve automatic identification. It is waterproof, antimagnetic, high temperature resistant, long service life, long reading distance, data on the label can be encrypted, and storage data capacity is large , The storage information can be changed freely, high-speed moving objects can be identified and multiple tags can be identified at the same time.
After decades of development, RFID has been widely used in various industries, and is infiltrating into various traditional industries, such as the intelligent management of clothing. Many clothing companies can automatically and real-timely combine RFID tags with clothing. , Realize clothing management intelligently. At present, RFID technology has gradually become an indispensable technical tool and means for brand clothing factories to improve clothing management, reduce management costs, and enhance core competitiveness.
1.2 Project objectives
The main purpose of this solution is to use the RFID technology’s long-distance fast batch reading and writing, unique identification and anti-counterfeiting and anti-theft characteristics to realize the fast batch receiving and sending operations of goods, and to record the attribute changes of a single piece of goods in the logistics and commodity circulation links, so as to achieve high efficiency The purpose of operation and real-time traceability is to help customers optimize warehousing and logistics operations, implement channel supervision policies, and promote product sales.
The specific construction goals of the plan include:
1. Give each piece of clothing a unique identification ID. By retrieving this ID, you can query the information recorded in the production, logistics, and sales of this product, so as to realize the timely tracking and tracing management of a single product;
2. When receiving the goods in the headquarters warehouse, use the RFID receiving channel equipment to quickly scan the whole box of the goods, generate and print the packing list, and automatically connect with the ERP system, and record the detailed list of each box in the database;
3. When shipping the warehouse, use RFID equipment to quickly scan the entire box of the goods, check the scanning results and the shipping notice, generate and print the shipping list of each box of goods, or the batch of shipping lists, and record in the database Each RFID electronic tag is associated with the delivery time of the goods, the destination of the goods, the agent number and other commodity attributes and commodity flow information;
4. Downstream agents are also equipped with RFID scanning equipment, and they can access the ERP software system of the brand through the Internet to perform the same operations, conduct fast and precise warehouse management, and collect information on the flow of goods from dealers and retail stores. Customers and agents and distributors at all levels can share data synchronously and manage collaboratively;
5. When picking goods in a warehouse or taking inventory in a store, the RFID handheld terminal can be used to quickly select the target goods according to the order to avoid wrong picking, missed inspection or multiple picking; there is no need for one-by-one operations to achieve efficient inventory;
6. When the market supervisor of the brand or agent needs to inspect the suspicious goods, use the RFID handheld terminal to scan the electronic label in the goods, you can inquire about the circulation history and order batch information of the goods, and identify the goods in time Authenticity and channel attribution;
7. When the product is sold in the store, the RFID operation console connected to the POS of the store can scan the label information of the sold goods, update the sales data, and set the EAS position of the label to the non-alarm state; when the product passes through the door of the store, it is anti-theft In the system, goods that are normally sold can pass without alarming, and clothing that has not passed the normal POS purchase process will trigger an audible and visual alarm, and can be used for fashion applications such as clothing pull shows;
8. The information stored in the RFID tag of each piece of clothing is protected by a password. Only the legal RFID device in the system can correctly collect or rewrite the label information, and illegal devices cannot collect it to ensure the safety and uniqueness of the information.
1.3 Scheme implementation plan
This solution builds a complete clothing supply chain management system based on RFID technology to realize automatic collection of relevant material information in the full life cycle of clothing. It not only needs to establish an RFID application environment within the company, but also involves suppliers, distributors, and Customers, logistics and transportation companies, etc.
The company’s implementation of a supply chain management system based on RFID technology can be divided into three stages as a whole:
1) Partial demonstration stage. At this stage, according to the actual situation and status of the company, select typical products or links with urgent needs, mature conditions, relatively independent, and certain representativeness to implement RFID solutions, such as a certain high-end style or partial finished product warehouse, specialty stores, etc. The main goal of this stage is to achieve partial results through the demonstration of RFID applications in typical products or typical links, and to explore the experience of applying RFID technology in clothing enterprises, and to play a demonstrative role in the comprehensive application of RFID technology in enterprises.
2) Enterprise application stage. After successful partial demonstrations, apply RFID technology to other links and all products of the enterprise, such as processing workshops, finished product warehouses, turnover warehouses, agents, specialty stores, etc., to form an application system for the entire process of clothing logistics and sales based on RFID technology. And realize the integration with other information systems of the enterprise, thereby comprehensively improving the comprehensive level of enterprise informatization and enhancing the market competitiveness of the enterprise.
3) Application extension stage. On the basis of the successful application of RFID technology by enterprises, from the perspective of the clothing supply chain, extend the application of RFID technology to the front-end and client-end of suppliers, apply RFID technology in procurement, distribution, after-sales service and other links, and cooperate with suppliers and third parties. The information system integration of external companies such as logistics and after-sales service providers constitutes a clothing supply chain management system based on RFID technology, thereby improving the market competitiveness of the clothing supply chain with the company as the core.
Chapter 2 System Structure and Function
Clothing has the needs of anti-counterfeiting, anti-theft, logistics distribution management and sales channel management. In the production process of clothing, an RFID card issuing machine is used to write some important attributes of a single piece of clothing into the RFID tag and attach the tag to the corresponding clothing. The uniqueness of the tag can be used as a clothing anti-counterfeiting identification. The electronic tag attached to the packaging box can be used for distribution and adjustment during the delivery process. At the same time, the RFID reader installed at the door of the specialty store can bring out abnormalities to customers. Alarm and anti-theft for clothing and other conditions.
Schematic diagram of the overall scheme of RFID clothing management
1. RFID electronic tag selection
This program will use disposable UHF RFID electronic tags. The product form is a transparent PET electronic label with adhesive backing.
This scheme adopts encrypted EPC coding rules. When using an RFID reader that is not authorized by this system to read the tag, the code content can be displayed, but the meaning of the code cannot be analyzed, thereby preventing the tag information from being forged.
At the same time, when the tag is initialized, the program write-protects the tag, that is, the coded content of the tag is protected by a password to prevent illegal writing.
Each tag has an EAS bit for anti-theft. When it is initialized, it is set to alarm state, and only when the normally sold goods pass through the store’s anti-theft system, it will not alarm.
2. RFID electronic tag data initialization
RFID electronic tags are continuous roll packaging before use. Before issuing electronic tags to processing plants, each tag needs to undergo data initialization, that is, write EPC codes with specific rules into the tags.
The tag initialization client program periodically downloads the production notice from the background system to the local computer for use when the RFID tag is initialized.
When initializing tags, the operator calls up the production notice in the program, selects the goods to be initialized, and after confirmation, the program drives the tag initialization instrument to complete the initialization operation of the corresponding number of RFID electronic tags.
After the initialization operation is completed, the client program uploads the initialization data to the back-end system server, and the code of each label and the association relationship with the product, processing plant, and production order are registered in the database.
3. Headquarters receiving operations
Deploy the RFID receiving scanning channel in the warehouse of the brand owner, and the receiving operation client program to receive the arrival of the processing plant and the return of the agent.
The client program regularly downloads the arrival notice from the background system to the local to prepare for the receiving operation. After the goods arrive, the operator calls out the arrival notice waiting to be received, and after verification and confirmation, drives the RFID receiving scanning channel to start scanning the goods box by box.
During the cargo scanning process, the program interface will display the shipment manufacturer, order number, product content, planned arrival quantity, actual arrival quantity, and arrival box number of the batch of goods. The above information will be temporarily stored in the client program, and will be uploaded to the back-end system when it is manually confirmed that the receiving operation is completed.
After the receiving scanning operation is completed, the program will upload the scanning results and record the corresponding attributes of each piece of goods in the database, including receiving time, receiving location, operator number, etc. And record the corresponding attributes of the order, including the order receipt quantity, receipt time, receipt difference, etc.
After the receipt scan job is completed, the program can generate and print reports such as the receipt details and the factory delivery variance details. The receiving operation is completed.
When the headquarters receives the returned goods from the agent, the client program receives the product information collected by the scanning channel and uploads it to the back-end system server. The server program is based on the goods preset during the headquarters shipment or later modified in the system. Distribution price and return policy, statistics of all the goods returned by the agent, and submit a report to indicate the reasonable and unreasonable return quantity, amount and other statistical data.
4. Headquarters shipping operations
Deploy RFID delivery scanning channels and client programs in the brand store warehouses for delivery operations.
The brand’s order management or warehouse staff log in to the system from the intranet, enter the pick-up or delivery notice, and the program regularly downloads the delivery notice and the goods data sheet to the local to prepare for the delivery operation. The content of the shipping notice includes the agent ID, cargo content and quantity details, planned delivery date, delivery address, agent price, return policy, etc.
The operator first calls out the delivery notice, and after verification and confirmation, drives the RFID delivery scanning channel to scan the goods one by one or continuously. The scanning result will be compared with the delivery notice or picking list. If there is an error, the operator will manually choose to rescan or continue the delivery task.
After the delivery scan is completed, the program will generate and print the packing list of each box, the delivery details of the entire order, and the details of the difference between the order and the actual delivery and other forms. The program automatically rewrites the corresponding actual delivery time, shipper, receiving address, agent ID and other items in the database, and records the completion of the corresponding delivery notice. This delivery operation is completed.
5. Office/agent collection and delivery operations
Offices or agents can install RFID single-piece cargo scanning equipment in their warehouses for receiving and shipping operations. Each scanning device is assigned a fixed device ID and is associated with the agent ID. Therefore, all goods passing through this device are associated with the agent ID.
When receiving the goods, scan the goods one by one. After all the scans are completed, upload the data to the system, and the warehousing operation is completed.
When delivering goods, enter the information of the recipient of the goods and the delivery details, scan the goods one by one, and upload the data to the background system after all the scans are completed, and the delivery operation is completed.
After each collection and delivery operation, the background system data is updated, and the headquarters can see the time, quantity, destination of goods and inventory of each agent. Agents can also log in to the system and see their own warehouse operation information.
6 Dealer management and anti-crossing goods management
With the rapid development of the market economy and online sales, the problem of fleeing clothing has become one of the most important factors affecting the brand image and corporate interests of clothing brands. At the same time, counterfeit products often lead to huge economic losses for businesses.
Anti-smuggling of goods is an important link in the management of the market sales chain. The phenomenon of “smuggling of goods” has seriously interfered with the normal marketing strategies and policies of enterprises for a long time, especially now that dealers often dump on Taobao and specialty stores have become consumers. After checking the model and size of the fitting room, you can purchase it directly on Taobao. This has seriously affected the brand image and the interests of other distributors. As a result, agents are afraid to place orders in large quantities, which ultimately affects the brand’s corporate benefits. Many companies have been committed to severely punishing the “smugglers”, and they have also thought of many methods and adopted some technological means, hoping to eradicate the smuggling. However, fleeing goods is still rampant, and companies still have many problems that cannot be solved. The reason is that the core problem of anti-smuggling management is that if an enterprise cannot control the flow of products, it will not be able to monitor and control the smuggling behavior.
Using RFID technology, after receiving and dispatching operations by the headquarters and agents, the circulation information of each piece of goods is recorded in the back-end system database. Use a fixed reader or wince handheld terminal to scan the suspicious goods, and you can query the detailed circulation information of the goods in real time. The terminal program interface can be customized according to needs, displaying important information such as goods and commodity files, attribution of dealers, and legal sales areas.
7 Store sales and anti-theft
Store management based on RFID technology includes three parts:
1. The normal sales of clothing, the record and update of the linkage invoicing system
2. Store multimedia display and promotion, that is, use a multimedia advertising terminal with a built-in RFID reader to identify current clothing information, and display related clothing promotion information and inventory information on the terminal to guide consumers to correct consumption and stimulate consumer desire.
3. Intelligent anti-theft based on RFID
When a piece of clothing is sold in the store, the customer takes the selected clothing to the front desk for checkout, and the waiter only needs to stack the clothing normally on the RFID console connected to the POS to complete the clothing information entry, in the POS software interface Click on the button to confirm the sale, and the reader under the RFID console will automatically rewrite the EAS setting status of the clothing label.
Shop anti-theft
When the goods pass the anti-theft system of the store’s gate, the goods that are normally sold can pass without the alarm. If the EAS setting is not modified by the POS, the label will trigger an audible and visual alarm. This product does not require computer control. It continuously sends EAS detection instructions by itself, and continuously detects whether there is electronic tag information set in the EAS alarm state within the magnetic field through 2 sets of antennas.
The product has a stylish and beautiful appearance and strong functions. It uses the same RFID electronic tag installed on the clothing in the logistics process to complete the anti-theft. There is no need to install a special EAS tag, which greatly reduces the cost of repeated investment and improves the corporate image and system reliability.
The RFID anti-theft channel developed by Yingxin adopts a special and innovative narrow-width antenna array technology. The antennas are installed in the panels on both sides of the store entrance, which can form a magnetic field covering a width of 3-5 meters and a thickness of less than 50 cm. Area, so that only when the product passes through the door frame, the information of the electronic tag attached to the product will be detected, and other electronic tag information outside the 50cm inside and outside the door frame will not be detected, thus avoiding unsold products around the door of the store False alarm.
The RFID reader has a relay output function inside, that is, when the reader reads a tag or a tag with a specific format, the reader closes the relay, which triggers the closure of the external relay and starts the alarm or alarm indicator. For RFID Label anti-theft has the following situations:
(1) The label of the clothing store needs to be recycled. In this case, the RFID reader installed at the door of the clothing only needs to read the label to trigger an external alarm.
(2) The label of the clothing store is not recycled. In this case, the clothing store can use the RFID reader to rewrite the label on the clothing that the customer is about to buy, and define a byte of data. When the byte is 0, it means Not purchased, if it is rewritten to 1, it means that it has been purchased. When the reader at the door reads an unrewritten tag, it will trigger an external alarm, and when it reads the rewritten electronic tag, it will not trigger an external alarm.
8 VIP customer management
Clothing stores or clothing factories can use RFID tags to apply for a membership card for VIP customers, and use RFID readers to automatically call up VIP customer related information, including VIP customer’s business direction, VIP customer’s previous visits, and VIP customer’s appointment and negotiation items And so on, based on this information, you can fully understand VIP customer information and conduct targeted conversations. Through the integration of existing user information, resources are shared within the entire company, so as to provide customers with faster and more thoughtful and high-quality services to attract and maintain more customers. You can also design a business process center based on existing information to manage customer relationships more effectively and reduce business costs.

Chapter 4 System Advantage Analysis
4.1 System advantages
The advantages of using RFID to intelligently manage clothing are shown in the following four aspects:
4.1.1 Intelligent management of anti-traffic goods
4.1.2 Intelligent supply process management
(1) Supply cycle control: Through the unique number of the supplier and the service quality certification, the supply time of each material is accurately calculated, and orders can be ordered as needed to ensure immediate production.
(2) Quality tracking: By matching the quality inspection form to the electronic label of the purchased product, the quality responsibility of the supplier can be effectively investigated.
(3) Entrusted processing control: Many manufacturers only manage their own brands, and generally entrust OEM manufacturers to manufacture and produce, and assign them to various OEM manufacturers to paste on the products through pre-designed electronic tags. It is easy to count during acceptance. Any quality problems found in the sales process can be directly investigated to the original manufacturer, and the remaining materials after commissioned processing can also be quickly calculated.
4.1.3 Intelligent warehouse management
(1) Multi-database collaborative operation: For the needs of circulation, the products of garment industry enterprises are often distributed in different warehouses in various places, so as to transfer goods, allocate goods, and replenish goods. There are also many types of warehouses, such as: finished product warehouse, raw material warehouse, circulation warehouse, turnover warehouse, scattered small warehouses, etc. The inventory of each warehouse needs to be monitored daily to ensure timely supply. Through warehouse management automation, the inventory of each warehouse can be checked at any time, so that the logistics process of products can be tracked in time.
(2) Warehouse receipt, delivery, and inventory work: The most important task in warehouse management is to ensure that the booked quantity is consistent with the actual quantity. The use of electronic tags can easily achieve the accuracy of the receipt record and the delivery of goods , Automated distribution, so that inventory will not be missed or lost.
(3) First-in, first-out: Every product has its lifespan. Due to the many types of products, it is difficult to ensure accurate first-in, first-out products through manual records and custodian records in actual warehouse management. Through the single tracking technology, a clock can be built in for each product, and the intact state of each product can also be recorded, so that the goods can be shipped out of the warehouse within the specified time limit.
(4) Out-of-stock alarm: When there is a shortage of a certain product in any warehouse, not only can the alarm be automatically prompted, but also the details of product composition such as model type, color, and size can be subdivided. That is, if a certain size of a certain style is broken, the custodian can immediately be reminded to replenish the goods in time.
(5) Statistics of slow-moving products: The backlog of products in the clothing industry is a very headache. Through the statistics of slow-moving products, the residence time of each product (subdivided into model, color, size) can be quickly found. Which products are unsalable or out-of-season, you can easily provide price reduction decisions or exchanges, and accelerate product sales and capital turnover.
4.1.4 Intelligent sales management
(1) Sales statistics: The statistics of daily sales reports are very important to the sales department of an enterprise. It requires accurate results as quickly as possible. Sales statistics include: statistics by style, color, location, size, etc., which can help the sales department allocate and replenish goods in time.
(2) Counter sales automation: The use of electronic tags can realize the functions of the portable POS machine in the monopoly counter, and can complete the functions of sales, return, counter inventory, inventory, collection and other sales automation operations; at the same time, it can generate various current-day functions Statistical reports are sent to the headquarters or local offices for sales analysis.
(3) Return control: In the market competition, all manufacturers are improving the quality of service and allowing customers to return goods. Through statistical analysis of returned goods, product quality problems can be accurately identified, and the responsible department, responsible unit and responsible person can be held accountable.
(4) Counter inventory and finding goods: Counter inventory and finding goods is a very tedious and error-prone task for each specialty counter. The use of handheld readers or data collectors can easily realize counter inventory and find goods, improve work efficiency, and will not cause any inventory errors (especially after using a single unique encoding method), and the inventory results can be quickly sent to the superior unit.
4.2 System benefit analysis
1) Through the development of RFID-based distribution management system applications, the automated management of logistics distribution and allocation of the chain system is realized, and the data collection and analysis capabilities of sales information, customer information, promotion data, product price change information, etc., are improved, especially for key points Customer service capabilities.
2) The on-time delivery rate of products has increased from the current 95% to 98%, the production cycle has been shortened by 15%~20%, the order processing time has been shortened from 1~2 days to 1~2 hours, and the inventory days have dropped from 206 days to 150 days.
