I. Overview
(1) System application background
First of all, large-scale production and industrial collaboration have made clothing supply chain management increasingly complicated. To some extent, it is almost impossible for us to know where a particular piece of clothing is produced; secondly, as retail stores continue to expand, The probability of poor management of the area of goods has greatly increased; again, the fashion elements of the clothing industry are changing rapidly, and the demand for diversification and individualization continues to increase. All these are destined to be very unstable and challenging in the development of the apparel industry.
Since entering the 21st century, enterprise supply chain management has entered a new period of development.byRFID(Radio Frequency Identification Technology) represented by the Internet of Things technology, represented by 3G mobile communication technology, represented by GPS positioning sensing technology has been relatively rapid development and application in the field of supply chain management. Modern enterprises pay more and more attention to the application of emerging technologies in IT systems to continuously improve and improve the management efficiency of the enterprise supply chain.
We have been committed to using emerging technologies to integrate the mature management experience of the enterprise itself to build a digital management system with modern commercial enterprises. Not only can it meet the requirements of the distribution operation mode in modern logistics, it is suitable for large-scale busy logistics distribution, ensuring high-quality data exchange in the supply chain, and at the same time, through tracking solutions and supply Improving its transparency in the chain can effectively improve the level of warehousing and logistics management, save labor costs, and play a huge role in the management of the commodity supply chain.
(2) System construction goals
Information integration, throughRFID, 3G communication, GPS and other technical means form an integrated system of supply chain, sales system, customer service, and decision-making information.
■ Establish a management platform system for apparel product information business process
On the basis of the existing information system, through the application of the RFID system, docking and integration with the existing system, the establishment of a commodity information RFID management information platform system, the interconnection of electronic label logistics information with the enterprise scheduling information system, improve management efficiency, and realize supply The whole process of the chain is transparent, and the operating cost of the enterprise is reduced.Decision-making basis data is fast and accurate, scientific data mining analysis
■ Create clothing productsRFIDAutomatic identification system
Equipped with RFID electronic tags for clothing and other commodities, combined with fixed readers, handhelds and other data collection methods, automatic identification and data collection of goods in and out of the warehouse, realizing automatic and fast inventory of clothing products, timely grasping the inventory quantity, monitoring inventory assets and clothing products Logistics and transportation, anti-counterfeiting and traceability of clothing products, automatic distribution, no shortage of goods.
■ Significantly reduce the workload of clothing inventory and search
Relying on manual clothing inventory work, especially in small warehouses, has a large workload and low efficiency. The clerk needs to classify, place and record the clothing based on his own memory in inventorying the warehouse, which is time-consuming and difficult to achieve. It is necessary to introduce advanced clothing inventory tools and methods to realize the automation of clothing inventory.
■ Improve the safety and reliability of the store anti-theft system
The existing clothing anti-theft system has low accuracy of the magnetic stripe anti-theft system and the magnetic stripe is easily weakened, so the probability of false alarms and false alarms is relatively high. Therefore, it is necessary to improve the existing RFID anti-theft system and adopt more reliable anti-theft technology.
■ Improve job satisfaction of store staff
Due to the repetitive work of the store staff over the years, coupled with the heavy work of the small warehouse itself, it is easy for the store staff to have certain negative thoughts about the work. Due to management deficiencies, store managers are also troubled by the management of the store, resulting in a decrease in store staff’s satisfaction with the store’s job. Through the technical transformation of the store management system, technical means can be used to make up for the shortcomings in management, and at the same time free the staff from the daily heavy and repetitive work of the store.
■ Collect data by technical means to reduce human error and ensure authenticity
Use RFID to collect product shipment information and GPS to collect staff location information. Ensure the reliability and authenticity of the basic data collection of the system.
2. Program introduction
(one) RFIDTechnical advantages
RFID is a non-contact automatic identification technology, which obtains information mainly through radio frequency signals and electronic tag chip communication. The electronic label chip has a globally unique identification code, which can be used to realize the judgment and control of anti-counterfeiting and counterfeiting. RFID tags are not like other ID recognition technologies. RFID technology allows multiple tags to be read at the same time, and the tag of each clothing item is tracked by the system, regardless of whether the clothing is packed in a clothing box in a warehouse or in other packaging boxes. Or fold it up and put it on a shelf. In the circulation links such as production and various distribution and distribution, the efficiency and accuracy of commodity inventory and packaging can be greatly improved. RFID technology also eliminates human error factors and does not require visual reading, which simplifies inventory management, so that pallets, crates and single items in the warehouse can be easily and quickly located, searched and used through the system . RFID technology has great application potential in the apparel industry.
RFIDElectronic label technology has the following technical advantages:
◆ Convenient and quick to read, can be efficiently and automatically identified, unlike barcodes that need to be visually identified;
◆ Fast recognition speed, high data collection efficiency, can collect hundreds of recognition target information at the same time;
◆ The use cost is low, and the one-time use design can be adopted;
◆ Strong environmental adaptability, anti-fouling, and recyclable design electronic tags have a service life of up to ten years;
◆ ID is the only one in the world, with high anti-counterfeiting security;
◆ The electronic label has a large information capacity, in addition to the identification code, you can also add the required information according to the company’s situation. Information can be stored in an encrypted manner, which has good confidentiality;
◆ The damage rate in the logistics process is greatly reduced;
◆ Meet the needs of mechanization and automation in the operation process.

according toRFIDThese performance characteristics of technology can play a role in the production, warehousing, distribution, retail and other links of the clothing industry.
In the production process, an UHF RFID electronic tag is attached to the clothing, and the RFID electronic tag can store the clothing such as name, grade, size, color, material composition and other natural attribute data. For customized clothing, the RFID electronic tag can also be used as a process card to achieve “flexible” customized clothing production.
■ Anti-counterfeiting and anti-crossing of brand clothing
In the production process of clothing, some important attributes of a single piece of clothing, such as name, grade, article number, model, fabric, lining, washing method, implementation standard, product number, inspector number, etc., are written into the RFID reader Corresponding electronic tags, and attach the electronic tags to the clothing. In this way, each piece of clothing is given a unique electronic label identification that is difficult to forge, which can effectively avoid the behavior of counterfeiting clothing, and well solve the problem of anti-counterfeiting and anti-crossing of brand clothing.
Attachment methods of electronic tags: implanted in clothing; made into nameplates or hang tags; adopted recyclable anti-theft hard tags, etc.
■ Automated warehouse management
In the warehouse management of factories, distribution centers, and retail stores, using the non-visual reading and multi-tag simultaneous reading features of RFID technology, dozens of FCL products with electronic tags attached to clothing pass RFID readers Complete accurate reading at one time, greatly improving logistics efficiency.
Quickly and accurately realize the management of procurement control, multi-database collaborative operation warehouse receiving and dispatching operations, first-in-first-out, out of stock alarm, unsalable goods statistics, sales statistics, broken code analysis, commodity allocation, and return and exchange control.
■ Anti-theft management
Attaching EAS with RFID technology to clothing products, if a thief steals multiple products at the same time, the system will know at a glance how many clothing the thief has stolen, what clothing it is, and which clothing. EAS using RFID technology can better solve the problem of theft of goods in stores.
■ Quick search for goods
Store useRFIDA very important function of technology is to realize non-contact quick search of goods, timely deliver the goods needed by customers to the hands of customers, avoid the loss of sales opportunities due to artificial “out of stock”, thereby increasing sales revenue.
■ Quick settlement
The use of RFID technology in retail stores can also achieve fast settlement such as POS. Reduce the waiting time of customers in line and improve customer satisfaction. It avoids potential losses caused by customers due to long waiting time and repentance of buying behavior.
■ VIP member management
VIP membership cards given to customers are also made with UHF RFID electronic tags. When customers enter the store, they will be recognized by the RFID device at the entrance of the store, and the information will be automatically sent to the front desk or the handheld computer of the shopping guide. Sales staff can immediately find the customer information, customer level, previous purchase information, preferences, and so on. Based on this information, sales staff can provide personalized recommendation services to customers, which not only makes customers feel at home, but also improves sales opportunities.
(2) System design
The system structure includes: access to the server/in/out client/handheld terminal and communication network, etc., as shown in the figure below:
The access server is responsible for real-time communication and data interaction with many clients. It is deployed in CS mode and includes RFID tag protocol processing middleware. It is responsible for parsing a large number of concurrent tag information and incorporating it into the database. Real-time information such as alarms should also be carried out with the corresponding business system. Real-time data interaction;
The warehousing client includes RFID reader access middleware, which is responsible for processing concurrent massive RFID tag information, filtering and screening valid data, anti-collision processing, and automatic comparison with order or delivery document information, and automatically issuing when it does not match Call the police. Pack and compress the tag information that needs to be uploaded, etc., and also provide manual intervention interactive interface;
The handheld terminal can be manually operated to collect information about a single piece of cargo, and can compare and alarm in real time. The collected information can be sent to the background system via WIFI or GPRS network, or it can be temporarily stored and forwarded.
(3) Business process
Warehousing
When the goods enter the warehouse through the warehouse entrance, the RFID information of each product is automatically collected by the import port reader. After pre-processing by the inbound access client, if it is a pre-ordered entry, it will be compared with the pre-accepted inbound order information For comparison, after all the order goods are in the warehouse, if there is an error or missing RFID tag information, manual intervention will be carried out. If the number or type of the goods is confirmed to be wrong, an alarm will be automatically sent to the business information platform; if other goods are in the warehouse, the The collected information is packaged and compressed and sent to the business platform system for filing, the back-end database is automatically updated, and product inventory records corresponding to warehouses and locations are added. According to the warehouse management information system, according to the pre-set positions of different types of goods, it can automatically prompt the corresponding goods positions where the goods currently in the warehouse are required to be stored.
Out of stock
When the business platform system generates a bill of lading and sends it to the warehouse outbound client, if there are a small number of multiple types of goods, the picker can download the bill of lading with the handheld machine, and manually scan and sort the goods according to the bill of lading. The handheld machine will automatically prompt when the sorting error occurs Call the police and correct it in time; if it is a single type of bulk cargo, the picker will arrive at the designated location and push the goods to the outbound port with a cart according to the bill of lading. The outbound port reader will automatically identify the information about the outbound goods, and the goods will be picked up after preprocessing. The single comparison judges whether it is accurate. If the verification is correct, the shipment will be made, otherwise an alarm will be issued and manual intervention will be prompted. The results of normal outgoing or manual intervention will be reported to the business information platform for filing by the outgoing port client, and the back-end database will be automatically updated, and the product inventory records of the corresponding warehouse and location will be deducted.
Secondary warehouse management
For secondary warehouses such as direct-operated stores, corresponding fixed or hand-held readers can be equipped according to the size of the goods, the inbound and outbound clients (can be on the same computer) are deployed, and business processes such as warehouse transfer or terminal sales can be added. Implement a similar business process model.
Inventory work process
RFIDThe warehouse management platform system can automatically perform warehouse inventory and location statistics, and automatically compare the back-end database when the inventory data is saved, and generate difference statistical information that is displayed on the terminal in real time, providing verification for inventory personnel. After the inventory is completed, the inventory difference report is automatically generated in the background for printing and verification.
