Attached to merchandise the two-dimensional code, bar code labels, just like commodity unique "identity card", marks the uniqueness and the uniqueness of each item. The emergence and application of RFID electronic tags have allowed traceability and channels for goods from production, packing, transportation, and sales.
Since 2000 , it can be called the upgrading stage of China's industrial automation system. At this stage, market demand and the scale of the industry expanded rapidly, and production, warehousing, and distribution technologies were comprehensively improved. Modern warehousing systems, sorting systems, and automated production line technologies have begun to be used in rfid automated production lines in various domestic industries, especially in tobacco, cold chain, medicine, new energy vehicles, machinery manufacturing and other industries.
Â
In the past two years, with the development of technologies such as the Internet of Things, big data, and cloud computing, more and more devices have been intelligently upgraded, and the identification and tracking of objects and devices requires the use of RFID technology. So, what is RFID technology? How does it relate to automated management ?
When it comes to the Internet of Things, radio frequency identification technology has to be mentioned. Radio frequency identification technology (RFID), a wireless system is a simple, consists of a card reader (or reader) and a transponder number (or tag) composition, so that the article can be achieved "speak" function, which Given the traceability of the Internet of Things, people can grasp the exact location of items and their surrounding environment at any time.
At present, products derived from RFID technology are divided into three categories: passive RFID products, semi-active RFID products and active RFID products. Among them, active RFID products have been gradually developed in recent years, and their long-distance automatic identification characteristics determine their huge application space. In the fields of remote automatic identification, such as smart hospitals, smart transportation, smart cities, etc. Has good market potential.
RFID tags and RFID handheld terminals are a pair of "good partners" in smart storage application scenarios. The staff puts the RFID tag outside the packing box for binding and review when entering the warehouse, searching and reviewing when leaving the warehouse, and scanning and reading through RFID handheld devices during inventory and searching . In doing so, the processes of receiving, putting on shelves, picking, replenishing, shipping, and inventory can be better completed, which is convenient and fast.
No inventory chaos, SaaS model of cloud invoicing, real-time synchronization and efficient collaboration on mobile phone PC , etc., are all significant signs that smart warehousing is different from traditional warehousing industry. In order to improve the efficiency of warehousing , technologies and equipment such as RFID electronic tags, cloud computing systems, and IoT sensors are needed to truly realize the intelligent recording and management of goods in automated warehouses.
Based on the advantages of large RFID data capacity, fast recognition speed, long service life, wide application range, convenient and fast reading, dynamic real-time communication, and tag data can be dynamically changed, the application space of RFID electronic tags is constantly expanding. In the field of industrial automation , RFID electronic tags are widely used to record product specifications, models, inventory and other information on the production line . Now it has become a major trend in the development of the entire industry. The application of RFID electronic tags can be seen almost everywhere in distribution centers, assembly workshops, warehouses with high frequency of shipments, small cargo transportation and picking operations .
In addition, RFID electronic tags can also be used in life scenarios including tracking cars, books, and computer equipment. RFID electronic tags can be implanted in animals to help identify lost pets. For food suppliers, RFID electronic tags can also help food companies track the source and place of production of packaged goods, so as to achieve product traceability and create a safety net for food safety.
The influence of interfering objects, the reading distance is too far, etc., will have a certain impact on the normal use of RFID electronic tags. Therefore, when using RFID readers , managers need to master the correct method of use. Maybe in a few years, RFID technology will have a more mature industrialization model from industrial manufacturing, use to management, and the true value of RFID technology will be in addition to automating the production line, < 1 2 >
