With the rapid development and application of RFID technology, the supply chain field will bring about a huge change. RFID technology has unique advantages such as long identification distance, fast and accurate, not easy to damage, and large capacity. The application of RFID technology has greatly improved the management efficiency and transparency of the supply chain. The warehouse management of RFID technology is the automatic data collection of the data of each operation link such as warehouse arrival inspection, warehousing, outbound, allocation, shifting, inventory counting, etc., so that the data of each link of the warehouse management is fast and accurate It is more intelligent and simplified for the enterprise in the management of warehousing goods.
At present, many companies are facing many problems in the issue of warehouse management:
1. Increased inventory investment budget;
2. Increase in logistics and distribution costs;
3. Increase in utilization rate of personnel and equipment in warehouse space;
4. Order process and long replenishment time;
5. The warehouse is chaotic, and it is time-consuming, inaccurate and labor-intensive to find materials;
RFID warehousing inventory management uses RFID wireless identification technology to verify the quantity and type of items in the warehouse in order to accurately grasp the inventory quantity.
RFID warehouse inventory is very efficient and intelligent features:
1. Automatic warehousing: The stable reading distance of handheld readers can reach 2-5 meters, and the reading distance of fixed readers can reach more than 12 meters. This effectively solves the problem that the barcode storage must manually scan the barcode in the past, realizes automatic storage and retrieval, and greatly improves the labor cost of storage and the efficiency of forklift usage.
2. Dozens or hundreds of tags can be read instantly: as soon as the tag enters the magnetic field, the RFID reader can instantly read the tag information; using RFID anti-collision technology and UHF fixed readers, it can be read instantly Dozens or hundreds of labels greatly improve scanning efficiency and reduce labor costs.
3. Unobstructed reading: When scanning traditional bar codes, the label cannot be obscured. However, RFID can penetrate non-metallic and non-liquid materials such as paper, wood, and plastics for penetrating communication without a light source. Provides a better scanning experience, which can quickly tally, find and take inventory. It is a warehouse management accelerator.
4. Large data capacity: the capacity of one-dimensional barcodes is 50Bytes, the maximum capacity of two-dimensional barcodes can store 2 to 3000 characters, and the maximum capacity of RFID electronic tags is MegaBytes. With the development of memory carriers, the data capacity also has a trend of continuous expansion. In the future, the amount of information that items need to carry will become larger and larger, and the demand for tags that can expand the capacity will increase accordingly.
5. Long service life and adapt to harsh environments: RFID’s radio communication method allows it to be used in dust, oil and other highly polluted environments and radioactive environments. It has a life span of more than 10 years (100,000 reads and writes); traditional barcode carrier tags Paper is easily contaminated. In addition, because the barcode is attached to the plastic bag or the outer packaging carton, it is particularly vulnerable to damage; the RFID label stores the data in the chip, so it can be protected from contamination, and the RFID has strong anti-pollution ability and durability.
6. Reuse: The content of the RFID tag can be changed. The direct benefit is that the RFID electronic tag can be reused, getting rid of the situation that the traditional barcode label can only be used once. Labels and ribbons)
7. Security: RFID electronic tags can not only be embedded or attached to products of different shapes and types, but also can set password protection for the reading and writing of tag data, which has higher security; because RFID carries electronic information , Its data content can be protected by a password, so that its content is not easy to be forged and altered, with higher security.
8. Small size and diversified shapes: RFID does not need to match the fixed size and printing quality of the paper for reading accuracy. It is more suitable for the development of miniaturization and diversified forms to facilitate embedding or attaching to products of different shapes and types. superior.
Generally, RFID electronic tags are affixed to the packaging and pallets of each goods, and detailed information such as the specific information of the goods and the storage location are written in the tags. Automatically collect and record relevant information when the goods are operated in each link of the warehousing, effectively manage the operation of cargo packing to reduce losses, record the product quality in each production process, quickly change the information on the electronic label, and implement each product simply and quickly The status of the link. The automatic collection of RFID technology can more effectively achieve quality supervision, so as to track the logistics of inventory goods throughout the entire process. It saves a lot of manpower, material resources and time, reduces the error rate and the probability of damage to goods, realizes fast and accurate inventory counting, and improves the overall transparency of enterprise logistics.
