RFID technology helps clothing warehouse management

As RFID technology matures, it has obviously been paid attention to by more and more companies and applied in various fields, especially in the field of warehousing and warehouse management. RFID technology can be said to be the most advanced, most convenient and most widespread after barcode management technology. Management technology means. It has penetrated into various aspects such as steel product production line accessories and finished product management, military training equipment management, aviation first aid equipment management, medical consumables warehouse management, etc. This time the company will develop a warehouse management plan that meets the needs of garment factory customers.

       The warehouse of a clothing company in Shenyang has 20 rows of metal hollow shelves. Each row of shelves is about 20 meters long, 4 meters high and 0.5 meters wide. They are double-sided and are used to stack finished garments. The company's original statistical method was manual recording. Every ten pieces of finished clothing were packed into a bundle. According to the height of the single-layer shelf, every four bundles were grouped into a group and placed in a single metal grid on the single-layer shelf. Because clothing is such a special item, it is necessary to distinguish sizes, materials, styles and other categories. When the output increases, manual management is prone to errors, causing losses. At the same time, manual management is time-consuming and labor-intensive, which increases a certain management cost. RFID technology is a non-contact automatic identification that uses radio frequency communication. Using RFID technology to manage the factory's clothing warehouse can effectively solve the current problems of low warehouse management efficiency, high error rate, and increased management costs. This allows managers to understand the real warehouse data in a timely and accurate manner, thereby improving the company's production efficiency and management level.

       The solution is based on RFID electronic tags, using white label tags with a size of 90*20mm and pasting them at the place where the clothing tag is made. The electronic label is written with clothing classification, size, model, category and other customer-specified information. The electronic label supports printing, and the face label can print information commonly displayed on clothing. The electronic label uses a polyester film as the substrate, with a built-in aluminum-etched ultra-high frequency RFID Antenna. It adopts the ISO 18000-6C protocol, can read and write more than 100,000 times, and is packaged in rolls. Match each electronic tag to a piece of clothing and encapsulate it on the clothing in the form of a hang tag.

       The main hardware equipment of the solution also includes a handheld terminal reader and writer, which uses a BN3028 industrial-grade handheld computer. The CPU uses Cortex-A53, an eight-core 64-bit, 2.0GHz high-performance processor. The system is upgraded to Android 8.1, 5.5-inch IPS color Display screen, resolution 720*1440. This series of handheld machines are independently developed and produced with a reading distance of up to 20 meters and can shield interference from metal shelves. Clothes are stacked densely. The handheld device can set the reading distance by adjusting the frequency to ensure accurate reading and no missed reading, and the label information between shelves does not interfere with each other. The fuselage is equipped with a handle and uses an ultra-high frequency module to work with dual-band 2.4GHZ/5Ghz networking.

       Another hardware that needs to be configured in the solution is an RFID printer, which uses a Zebra ZT410 professional-grade machine that can print external label information.

       The customized RFID warehouse management designed for Shenyang Garment Factory can not only organize inventory effectively in real time, understand the real data information of the warehouse, but also realize the function of automatic inventory. After the clothing products come off the production line, they are labeled and hung with tags. After the electronic tags are issued and labeled, each piece of clothing is equivalent to having its own exclusive electronic identity information. When entering the warehouse, use the handheld device to scan the electronic tags on the clothing to read the information, and transmit it to the management system through the wireless network with full coverage of the warehouse. The system automatically enters the clothing entry information; when leaving the warehouse, the RFID handheld device is also used to electronically tag the clothing. After the information is scanned and verified with the shipping order, the outbound work is completed. The handheld device also transmits the outbound information to the management system, and the system automatically enters the garment outbound information; the system can issue an inventory to the handheld terminal every one month or ten days. After the handheld machine receives the inventory task through the network, the staff will conduct inventory inventory in the warehouse. After the inventory, the data will be sent back to the management system and compared with the information in the system to facilitate the work of managers.

       Garment factory managers can view inventory information at any time through the warehouse management platform, including inbound and outbound information, real-time inventory information, etc., and quickly obtain real data on inventory Assets. The establishment of a clothing warehouse information management system can effectively improve warehouse management efficiency. The fully automated management method greatly liberates the labor force, improves production efficiency, reduces manual error rates, and realizes the transformation from traditional manual management to technological management. It has evolved from post-management to real-time management, enhanced the overall management capabilities of the enterprise, and reduced enterprise management costs.
