Detailed explanation of the current application status of RFID technology in clothing production

my country is the world's largest clothing producer and exporter, and clothing companies have made outstanding contributions to the rapid growth of GDP. However, most garment enterprises still use traditional production management methods, with a low degree of informatization and obvious problems and disadvantages, which are mainly reflected in the following aspects: the inability to grasp the actual production status and material status, the inability to allocate and adjust tasks and materials in a targeted manner, and employees The effective production time is often less than 60% to 70% of the working hours; product quality problems cannot be accurately traced to the person responsible, and quality supervision cannot be strict, and the product quality level is low; the flow of materials between each link of production cannot be accurately tracked, and materials are lost and wasted. Frequent, costs are artificially increased; the real-time progress of various production tasks cannot be controlled, the risk of overdue orders is high, and multi-task production resource scheduling and coordination are difficult.

These problems have seriously affected the overall efficiency of clothing manufacturing enterprises. Since 2008, with the appreciation of the RMB, rising labor costs, reduced external demand caused by the financial crisis and other unfavorable factors, the garment industry has faced greater pressure to survive. For garment enterprises to continue to survive and develop, it has become very necessary to use information technology to solve existing problems in production management and improve the core competitiveness of enterprises.

Problems and solutions to informatization of clothing production

Clothing manufacturing enterprises generally have the characteristics of multiple product styles, complex processes, large batches and small batches, and high requirements for personalized orders. This is reflected in the information model, which is a large amount of information, many types, complex associations between information, and complex processing rules. To realize production information management, clothing companies first face a problem: how to collect and provide real-time and accurate bottom-level status information such as a large number of materials, semi-finished products, personnel, and equipment during the production process to management.

Traditional information collection methods cannot solve this problem. For example, manual recording methods cannot guarantee the real-time and accuracy of data; the recognition rate of barcode labels is affected by dust, fiber pollution and dynamic characteristics of materials in the clothing workshop, which will cause reduced reliability. The lack of effective information collection means is one of the important reasons why information systems such as traditional MES cannot fully play their role in the clothing production process.

The characteristics of RFID technology determine that it has the following advantages in collecting production process information:

1. Seamless integration of production logistics and data information flow can be achieved without affecting the normal operation of production materials;

2. Using the electromagnetic field spatial coupling method, it can be used normally in an environment full of dust, fiber and other pollution in the workshop;

3. The tag has information reading and writing functions, which can realize localized saving and reading of production object information;

4. The label adopts a globally unique identification code and a complete security authentication mechanism, which can prevent label forgery and malicious tampering of data.

Current status of application of RFID technology in clothing production

Although RFID technology has obvious advantages in production informatization, the application of RFID in domestic and foreign garment manufacturers is still immature. In a small number of application cases, electronic tags are only used to replace paper work orders to Store information, and RFID technology has not been truly utilized. The advantages. There are several main reasons for this situation:

1. Domestic apparel companies are mostly in the lower reaches of the industrial chain, with low profit margins and cost sensitivity, and are unable to introduce expensive foreign industrial RFID equipment and systems.

2. It is quite technically difficult to apply RFID technology to the clothing production process. Domestic research in this field started late, with more research on system architecture and software levels, and a lack of research on industrial RFID Readers, middleware, and real-time information transmission. Research and breakthroughs in underlying key technologies such as data processing and data processing.

In response to the application needs of RFID technology in clothing production informatization, relying on the national 863 project funding, Beijing Sanbo Zhongzi Technology Co., Ltd. focused on the applicability and application key technologies of RFID in the clothing production process, and constructed an RFID-based clothing production informatization Management system to solve problems existing in traditional clothing production process management.

Overall design and application implementation of clothing production information management system based on RFID

The relevant links in the production process of a typical garment processing enterprise mainly include: formulation and release of production tasks, receipt of raw and auxiliary materials, processing and production, quality inspection, and finishing and packaging, etc. Targeted application of RFID technology in the production links of typical knitted garment enterprises, collecting on-site information from each link and summarizing it to the enterprise information server, building an RFID-based clothing production information management system, which mainly realizes production task progress control, production material tracking and core production links. Real-time monitoring and scheduling functions.

Production task progress control

In order to achieve real-time collection and control of the progress of each production task, an electronic label task card is generated for each production task from the time it is formulated and released. Task cards hold the necessary task information and are held by the production administrator for that task. Each production process link of raw material collection, processing and production, quality inspection and packaging is equipped with RFID reading and writing equipment, which is used to collect or write information related to task progress and upload it to the enterprise information server for management to view and process in real time. .

The formulation, assignment and management of production tasks are completed by the planning department. When the planning department assigns each task, the relevant content of the task is written into a 13.56MHz electronic tag (task card) and sent to the task manager. The data storage of the task card is divided into UID area, basic information area and process information area. The UID area is an independent partition that stores the globally unique code of the tag. It is solidified when the tag leaves the factory and cannot be changed. The basic information area stores task information such as task number, quantity, style, delivery date, etc. Only the planning department has write permission, and other production links only have read permission for this area; the process information area divides different sub-areas for different production links. Each link can write or read corresponding information in the corresponding sub-area as needed during the production process.
