 First, the project background

  In China's textile and garment industry, we have begun to have the awareness of supply chain transformation. Many enterprises have relied on the early intervention supply chain management system to position themselves in the global market and take the road of differentiated positioning and differentiated operation. In the fierce competition, it shows its own advantages. As the world's largest shirt OEM, Hong Kong Esquel Group has extended its reach to the upstream source of the industry – starting with cotton planting, covering cotton spinning, weaving, knitting, yarn dyeing, finishing, garment and sales. Link. Moreover, they use RFID technology, from cotton picking, processing, to packaging inspection, the production of various places through the Internet for timely information communication and visual monitoring, eliminating the time and manpower of manual inspection, its efficiency and market responsiveness is far higher For similar companies. At the same time, many domestic clothing brands are exploring and trying to use RFID technology to solve the increasingly serious problems of anti-counterfeiting/anti-smuggling.

  On the one hand, textile/clothing enterprises use RFID technology and other information technology because of management needs. On the other hand, government agencies are also striving to promote the information management level of textile/clothing enterprises. "China Printing and Dyeing Industry" The Plan clearly states that the full application of digital technology, information technology and biotechnology is the main direction of the progress of the “Twelfth Five-Year” printing and dyeing technology.

  1.1 Introduction to Radio Frequency Identification (RFID) Technology

  RFID is the abbreviation of Radio Frequency Identification, namely radio frequency identification, which is a non-contact automatic identification technology. RFID can be traced back to the Second World War (about 1940), when the main function was used by the British to distinguish between enemy and British aircraft. In recent years, with the development of large-scale integrated circuits, network communications, information security and other technologies, as well as the world's number one retailer Wal-Mart and the US Department of Defense, RFID has been rapidly applied to smart grid, transportation, logistics industry, medical health, Fine agriculture, animal husbandry, finance and service, industrial and automatic control, smart home, environmental and safety testing, public safety, national defense military, smart city and other industries and fields.

  RFID technology has non-contact, fast scanning, high recognition efficiency, not easy to damage, suitable for harsh environment, easy to operate, fast reading and writing speed, large amount of information storage, one card multi-purpose, anti-collision, secure encryption performance, repeat Usability, tracking and positioning characteristics.

  RFID technology is divided into low frequency, high frequency, ultra high frequency, active, etc. according to the frequency band. Based on the requirements of this project, UHF RFID is adopted in this project.

  Second, the overall idea of the system

  2.1 Scheme design ideas

  Based on years of experience in RFID system integration and long-term close cooperation with many internationally renowned RFID product suppliers, the RFID technology and industry customer business are fully summarized and refined, forming a “architecture-based, customized-based, business-first "RFID management system construction model." Namely: through RFID product selection design and build a mature and stable system architecture, through customization to meet individualized hardware requirements and software systems, through professional business analysis and system implementation services to ensure project success.

  1) Based on the world's leading hardware solutions for Impinj UHF RFID products and technologies, implement a service-oriented SOA software solution based on the Microsoft (.Net).Net Framework framework to build a qualified RFID fabric library management system.

  2) Fully consider and investigate fabric management characteristics and e-commerce platform characteristics, and organize projects that are designed to be reliable, easy to use, integrated, maintainable, scalable, and manageable.

  3) Promote system construction based on the principle of “overall planning and step-by-step implementation”. The system is built on a unified system framework, and the overall business needs analysis is carried out. After the pilot runs steadily, the experience is summed up quickly and comprehensively.

  2.2 System Application Architecture

  The system application architecture is divided into three logical levels: the acquisition layer, the application layer, and the presentation layer.

  2.3 RFID management design

  2.3.1 Label Management

  Electronic label management provides functions such as initialization (new), verification, query, modification, and logout of RFID electronic tags.

  The electronic label initialization mainly completes the processing of fabric samples to the library, writes the electronic label code (EPC), prints the electronic label information, binds the fabric label and fabric, binds the shelf label and the shelf, and verifies the basic work before the circulation of the electronic label. . After the basic information of the recorded fabric sample and the electronic label are bound to the fabric, the electronic label is pasted onto the fabric sample, and the security code of the electronic label is activated and then placed on the shelf. The system provides convenient modification functions to modify the electronic label information and record the changes in the system. For damaged fabric electronic labels or destroyed fabrics, the system provides the ability to unregister electronic labels.

  2.3.2 Storage Management

  After the fabric samples provided by the fabric supplier are returned to the center or the fabric samples returned from the warehouse, the fabric samples need to be sorted and the warehousing process is performed.

  2.3.3 Outbound Management

  When organizing or participating in fabric-related exhibitions or batch-receiving fabric samples, it is necessary to package the fabric samples to perform the outbound process.

  Third, the key technology design

  3.1 Technical Design Principles

  In terms of technical standards, UHF RFID products must comply with the EPCglobal UHF Class 1 Gen2 and ISO 18000-6C international standards in accordance with the "Uniform Standards" principle.

  In terms of technical route, according to the industry information requirements of the “Unified Platform”, the system adopts the Microsoft (.Net).Net Framework framework to implement service-oriented SOA software solutions, using hardware solutions based on the world's leading Impinj UHF RFID products and technologies. Program.

  In terms of technical architecture, the concept of Web services-based architecture and multi-layer architecture are used to guide the system design, to realize the separation of presentation layer, WEB service layer, business logic layer and data layer, and to ensure the openness and scalability of the system from the architecture. Sex and reliability, establish an information application platform that can be assembled and defined according to business needs.

  In terms of system integration, data interaction with the e-commerce platform of the fabric network is achieved, and the data of the fabric library and the fabric network are consistent, and the information is automatically exchanged.

  3.2 System Deployment Architecture
