1. Current situation of garment enterprises

Color, style and variety change rapidly, which is the characteristic of clothing products. Therefore, there are higher requirements for the management, production, inventory, distribution and turnover speed of clothing production enterprises. Seasonal varieties should be quickly cleared out of the counter and replaced with new varieties. Inventory can not be overstocked, overstocked products will cause great burden to enterprises. Control the quantity of inventory to ensure that the sales department has the right varieties on the counter to meet the needs of customers; At the same time, to ensure that most of the products can be sold, and will not produce a large number of unsalable inventory is the key problem to be considered by shoe and hat clothing enterprises. At the same time, garment enterprises often encounter the following problems: human factors caused by the wrong loading, missing loading, multi loading and other packing data statistics is not accurate and slow; Inventory needs a lot of manual work and takes a long time to complete; Product delivery also requires a lot of manual work, and the statistics is slow, which often leads to long supply cycle, directly affecting the production efficiency of enterprises; Inventory data statistics are not timely and accurate, which will also affect the production efficiency, such as: replenishment cycle is too long, etc; It is easy to make mistakes in inventory management; It’s not clear where each product is, or how many products there are in a certain location.

For garment enterprises, personalized service requirements are very strong, most of them belong to labor-intensive enterprises, and their degree of automation is relatively low, which brings great difficulty to the realization of garment industry informatization, so the pulling role of informatization is very prominent. The business process of clothing enterprises is very complex and tedious. Many clothing enterprises need to deal with hundreds of inventory units every day, and manage a variety of styles and supply chain management. In order to prevent the phenomenon that on the one hand, the monopoly stores are out of stock, and on the other hand, the warehouses of branches and factories are overstocked with a mountain of inventory, it is necessary to put the monopoly stores and factories in order Integrate the inventory information of branch and factory. In order to strengthen the purchasing and inventory control, garment enterprises need to improve the transparency of supply chain management, to be able to accurately track raw materials, processing processes and final products. In addition, reducing channel cost is also an issue that enterprises must consider. In this highly complex business management, accurate prediction, material procurement management, production planning and distribution management are particularly important. Facing these problems. RFID (radio frequency identification) technology has become the best guide for those garment enterprises who are trying to improve the brand value.

2 overview of RFID Technology

Radio frequency identification (RFID) is a non-contact automatic identification technology. It can automatically identify the target and obtain the relevant data through the radio frequency signal, and can work in all kinds of harsh environments without manual intervention. RFID technology can identify high-speed moving objects and multiple tags at the same time, which is fast and convenient to operate.

The most basic RFID system consists of three parts: tag, which is composed of coupling elements and chips. Each tag has a unique electronic code, which is attached to the object to identify the target object; Reader, a device for reading (and sometimes writing) tag information, can be designed as handheld or fixed; Antenna, which transmits RF signal between tag and reader. The basic workflow of the system is that after the tag enters the magnetic field, it receives the RF signal from the reader, and sends the product information stored in the chip with the energy obtained by the induced current, or actively sends the signal of a certain frequency: after the reader reads the information and decodes it, it is sent to the central information system for data processing. Compared with the traditional bar code and two-dimensional bar code, RFID technology has many outstanding advantages: non-contact operation, long-distance identification, mechanical wear, long service life, and can work in a variety of oil, dust pollution and other harsh environment; it can identify high-speed moving objects and identify multiple electronic tags at the same time; the reader has a physical interface that is not directly open to the end user, Ensure its own safety; In the aspect of data security, in addition to the password protection of the electronic tag, some algorithms can be used to realize the security management of the data part; There is a mutual authentication process between reader and tag to realize secure communication and storage.

3. RFID technology application brings new “revolution” to garment enterprises

3.1 application link

3.1.1 accurate packing

General clothing sorting and packing have certain restrictions, such as how many pieces of clothing of the same style (regardless of color and size) can be packed in a box is given. Therefore, in general, there will not be more or less packing in packing, but the same product of different models (the same size) will appear sorting error phenomenon, so in order to meet the requirements of packing labeling, we must manually intervene in packing, that is, to achieve the accuracy of packing quantity and type. This is a foundation to ensure the accuracy of data collection in the following aspects of RFID technology.

3.1.2 shorten the supply cycle

Through the way of wireless communication for data interaction, so it greatly improves the efficiency in the production of products offline, to the warehouse, inventory, and then to the warehouse out.

3.1.3 inventory management

After the finished products are packed off the production line, RFID tags are used for unique identification, and information collection is carried out for the links of packing, loading location and pallet loading. So as to realize the effective and accurate positioning of finished products in inventory management, realize the real-time dynamic inventory of finished products, establish a rapid response inventory management system, and eliminate the possible obstacles in inventory management.

3.2 workflow

3.2.1 marking

When the production task list is issued, the label printer will retrieve the task list data (such as the name, number of pieces, style, color, etc.) and print the corresponding labels according to the packing number (such as 10 products packed in a box). The labels can store the corresponding information of 10 products (the corresponding data is the style, color and other related information of these 10 clothes), It can also exist in the form of serial number made by the manufacturer, which acts as a bridge and corresponds to the product information in the background database.

3.2.2 packing

According to the specification of product packing, packing according to the given quantity.

3.2.3 labeling

Put the printed label on the box of the clothes.

3.2.4 warehousing

The advantages of multi-target identification of RFID are very obvious when it is put into storage. The reader antenna is arranged at the door of the warehouse, which can achieve fast and accurate information collection and print the list of products into the warehouse no matter single box or multiple boxes.

3.2.5 inventory

The completion of the inventory can be carried out in the form of high-frequency handset. In order to save the cost, it can also be carried out in the form of weekly reader. The latter can remove the products from the warehouse by trailer, and then push the products into the warehouse while the reader is working, which requires more manpower and warehouse space.

3.2.6 issue and print out product list

According to the customer’s delivery date, delivery should be made. When the products are out of the warehouse, they are loaded and transported away. When they are out of the warehouse, the system can read the number of boxes and other information of the products out of the warehouse, so as to ensure the accuracy and speed of the shipment. Then it can print out the shipping list and compare with the customer’s orders, and check whether there are over loading, missing loading, wrong loading and other situations.
