Chapter 1 Introduction to RFID (Radio Frequency Technology)
RFID is a non-contact automatic identification technology realized by radio frequency communication. RFID tags are small in size, large in capacity, long in life, and reusable. They can support fast reading and writing, multi-eye identification reading, non-visual identification, mobile identification, positioning and long-term tracking management.
In recent years, RFID technology has entered the stage of commercial application. At present, RFID technology has been continuously combined with Internet, communication and other technologies, and has been applied to many fields such as industrial automation, commercial automation, transportation, logistics, supply chain management, public information services, etc., gradually realizing global item tracking and information sharing, Significantly improve management and operation efficiency and reduce costs. RFID technology is considered to be one of the most promising information technologies in the 21st century.
Chapter 2 Demand Analysis
This warehouse management system is a management system that collects information in real time at all stages of clothing from production off-line, to entry into the warehouse, and finally to product delivery.
At present, there are mostly two data collection methods in the production process: one is manual collection and the other is bar code collection. Although companies that use bar codes for data collection save a lot of human resources and time than manual collection, as With the development of science and technology and the requirements of various companies for high-efficiency production lines, the application of barcodes has also reached its bottleneck, because it cannot achieve multi-batch, long-distance, high-speed, and hostile data collection. Limiting the efficiency of enterprises in the production process, the emergence of RFID (Radio Frequency Technology) not only solves these problems encountered by barcodes, but also has the advantages of convenient and fast reading, large data storage, and recyclable use. People are paying more and more attention, and the application industries are getting wider and wider.
2.1 Status description
At present, your company’s product information collection is still in the stage of a large number of manual operations from clothing production offline and packing; to entering the warehouse; taking inventory; out of the warehouse. The packing data statistics of wrong packing, missing packing and multiple packing caused by human factors are inaccurate and slow; inventory takes a lot of manual work and a long time to complete; product delivery also requires a lot of manual work, and statistics are slow, often causing The supply cycle is too long, which directly affects the production efficiency of the enterprise; and the untimely and inaccurate inventory data statistics will also affect the production efficiency, such as: the replenishment cycle is too long. If each product is labeled, all the above problems can be overcome. However, because your company takes into account the cost issue and how much input is required for a single piece of clothing labeling, so you use the clothing to be packaged and labeled according to the box.
2.2 System goals
Use RFID technology to solve the current problems of inaccurate and inefficient data collection and low data utilization in the process of clothing from offline to delivery, and low data utilization, so as to achieve accurate and rapid product packing, storage, and shipment cooperation to shorten the delivery cycle , Improve the production efficiency of enterprises.
2.2.1 Precise packing
General clothing sorting and boxing have certain restrictions. For example, how many pieces of clothing of the same style (regardless of color and size) can be packed in a box are given. Therefore, there is generally no problem of over-packing and less-packing in the packing. However, products of different models (the same size) of the same product will have sorting errors. Therefore, in order to meet the packing and labeling requirements of your company, you must Manual intervention during packing is to ensure the accuracy of packing quantity and style. This is a basis to ensure the accuracy of the data collection in the subsequent links of the system.
2.2.2 Shorten the lead time
The most popular way to shorten the supply cycle in the world is to use quick response QR technology, JIT timely production method, EOS electronic ordering system based on EDI technology and OPS order processing system to achieve the goal of shortening the supply cycle, and these technologies In the data collection, the data collection method is either manual entry or barcode. The RFID tag technology is far more efficient than these methods. It interacts with data through wireless communication, so it is in the production of products off the line, to the warehouse, and inventory. , And the efficiency is greatly improved in these links of outbound.
2.2.3 Inventory management
Inventory management is a very important part of a modern enterprise. The establishment of a quick-response QR inventory management system is the key to achieving rapid purchase, delivery, and replenishment. The inventory management of the finished products of the enterprise mainly includes the identification, positioning, stacking, and access of finished products. In terms of library, inventory, etc. The finished products are uniquely identified after being packed off the line and packed with RFID tags, and information is collected in the links of packing, loading positions and pallets, so as to realize the effective and accurate positioning of the finished products in the inventory management, and realize the real-time dynamic inventory of the finished products , Establish a quick response QR inventory management system to eliminate possible obstacles in the inventory management link.
Chapter 3 System Process and Program Overview

Operation process diagram
3.1 Imprint
When the production order is issued, the label printer retrieves the order data (such as the name of the garment, number of pieces, style, color, etc.), and prints the corresponding label according to the number of boxes (such as 10 products in one box). The label can be Store the information corresponding to 10 products (the corresponding data is the style, color and other related information of the 10 pieces of clothing), and it can also exist in the form of numbering established by the manufacturer, which acts as a bridge to correspond to the product information of the back-end database.
3.2 Packing
According to the product packing specifications, pack the given quantity.
3.3 Box labeling
Stick the printed labels on the boxes where the clothes are packed.
3.4 Warehousing
The advantages of multi-target recognition of RFID are very obvious when entering the warehouse. The reader antenna is arranged at the door of the warehouse. Whether it is a single box or multiple boxes, it can achieve fast and accurate information collection. You can also print a list of products in the warehouse.
3.5 Inventory
The completion of the inventory can be carried out by means of high-frequency handsets, and in order to save costs, it can also be carried out in the form of a fixed reader/writer. The latter can move the product out of the warehouse with a trailer, and then push the product into the warehouse with the reader working, so that the manpower required and the warehouse space are relatively large.
3.6 Out of the warehouse and print out the list of products out of the warehouse
According to the customer’s delivery date, the delivery must be carried out. The product is shipped out of the warehouse and then loaded into a truck. When it is out of the warehouse, the system can read the number of boxes and other information of the product out of the warehouse, ensuring the accuracy and speed of shipment. Then you can print out the shipping list and compare it with the customer’s order, and check whether there is any over-installation, missing installation, wrong installation, etc.
Chapter 4 System Topology Diagram and Flow Chart
This WMS (Warehouse Management System) can be integrated with other software, including production operation and quality management system (WIP/QA), material tracking system, intelligent marketing system (SRS), enterprise resource planning system (ERP), to provide users with strong support Ability to manage the flow of goods to help the company plan human resources, materials and tools, site utilization, financial arrangements, etc.
