What are the types and applications of UHF RFID electronic tags?
What are the types and applications of UHF RFID electronic tags? At present, China's RFID technology is constantly developing. According to different working frequencies, RFID tags can be divided into different types such as low frequency (LF), high frequency (HF), ultra high frequency (UHF), and microwave. Different bands of RFID work differently. RFIDs in the LF and HF bands generally use the principle of electromagnetic coupling, while RFIDs in the UHF and microwave bands generally use the principle of electromagnetic emission. To use them properly, you must first select the appropriate frequency. Each frequency has its characteristics and is applied in different fields. Today I will explain to you the types and applications of UHF RFID electronic tags.
I. Composition of UHF RFID electronic tags
UHF tags are composed of three parts: chip, antenna, and packaging scheme. The chip determines the core function of the tag, the antenna design determines the level of tag performance, and the packaging scheme determines whether the tag is suitable for the application environment.
Advantages of UHF RFID electronic tags
1. It can identify high-speed moving objects, and can also read multiple objects at the same time, which has the following advantages:
2. Strong penetrability and resistance to harsh environment.
3. Strong security and confidentiality.
4. Reusable, large data memory capacity.
Third, UHF RFID electronic label standard protocol
At present, the common UHF RFID air interface protocols in China include international standards, national standards, industry standards, and enterprise standards. The most popular standards are 6C and 6D standards, namely ISO / IEC 18000-6C (63), ISO / IEC18000-6D (64), and the Chinese national standard GB / T 29768- 2013
Four, UHF RFID electronic tag frequency band
1.Global coverage of UHF electronic tag frequency bands varies
2.China's frequency bands 840 ~ 844MHz and 920 ~ 924MHz
3. EU frequency band 865MHz ~ 868MHz Japan frequency band 952MHz ~ 954MHz.
4.Hong Kong, Thailand, Singapore 920MHz ~ 925MHz
5.U.S.A., Canada, Puerto Rico, Mexico, South America frequency band is 902MHz ~ 928MHz
Five, the application of UHF electronic tags
The UHF RFID market has a wide range of application scenarios. It has the advantages of being able to read multiple tags at one time, long distance recognition, fast data transmission, high reliability and long life, and resistance to harsh outdoor environments. Can be used for asset management, production line management, supply chain management, warehousing, anti-counterfeiting traceability of various items (such as tobacco, alcohol, medicine, etc.), retail, vehicle management, and so on.
1. Vehicle management
Through the special short-range communication between the on-board electronic tag installed on the vehicle's windshield and the radio frequency antenna on the ETC lane of the toll station, the computer network technology is used to perform background settlement processing with the bank, so that the vehicle does not need to stop when it passes the road and bridge toll station The purpose of paying road and bridge fees.
Electronic license plate is an application of the subdivision, extension and improvement of the Internet of Things technology. An electronic license plate label is installed on a motor vehicle, and the RFID electronic label is used as a carrier of vehicle information. When passing through a section equipped with an authorized radio frequency identification reader, the data on the electronic label of the motor vehicle is collected or An advanced technology for writing and realizing digital management of all vehicles.
3. Traceability of product anti-counterfeiting
Through the application of RFID technology in all aspects of enterprise product production, it realizes anti-counterfeiting, traceability, circulation and market control, protects corporate brands and intellectual property rights, and safeguards the legitimate rights and interests of consumers.
4.Warehouse logistics pallet management
The existing warehouse management introduces RFID technology to automatically collect data for each operation of the warehouse, such as inspection of incoming goods, storage, delivery, transfer, relocation, inventory check, etc. Speed and accuracy, to ensure that enterprises accurately grasp the real data of inventory in a timely manner, and reasonably maintain and control corporate inventory.
Laundry tags are resistant to high temperatures and rubbing, and are mainly used in the laundry industry to track and check the laundry washing situation. The label uses silicone packaging technology, which can be sewn, hot or hung on towels and clothing for inventory management of towels and clothing products.
By sewing a button-shaped (or label-shaped) electronic tag on each piece of linen, the linen is scrapped (the label can be reused, but does not exceed the life of the label itself). Will make the user's laundry management more transparent and improve work efficiency. High temperature resistant laundry labels are widely used in textile factories, linen professional washing and laundry, etc.
6. Clothing management
Garment management introduces RFID technology into the existing clothing warehouse management, which can automatically collect data on the various operations of the clothing warehouse, such as inspection of goods arrival, storage, delivery, transfer, relocation, inventory check, etc., to ensure the warehouse Manage the speed and accuracy of data input in all links, ensure that the enterprise accurately grasps the real data of the inventory in a timely and accurate manner, and reasonably maintain and control the enterprise inventory.
UHF RFID technology can be used to informatize all aspects of clothing production, product processing, quality inspection, warehousing, logistics and transportation, product sales, and provide managers at all levels with real, effective and timely management and decision support information. Supporting the rapid development of business will solve most problems.
7. Live bird management
The UHF RFID foot ring electronic tag gives each live bird a unique "identity card", and traceability management from seedling, quarantine, slaughter, processing to sales of live birds, effectively preventing food safety of live birds. Main application areas: It is worn on chickens, ducks, geese and other poultry, and is widely used in food traceability and safety supervision in seedlings, breeding, production, epidemic prevention, sales and distribution.
8.Pig traceability management
Qualified pork white strips are bound to radio frequency identification traceability tags, and the pork code obtained by the RFID identification channel at the factory is automatically associated with the RFID identity card information of the downstream vendor obtained by the RFID traceability all-in-one machine. At the same time, the all-in-one is also connected to the electronic scale to obtain the weight, and the all-in-one prints the meat transaction certificate of the traceability system. The batch of ex-factory meat traceability code, weight, downstream buyer and other information are uploaded to the government's traceability supervision system at the same time. Each piece of pork corresponds to the sole merchant or operator.
9. Tire management
By embedding RFID electronic tags on tires, each tire becomes an effective data traceability carrier. With the tire information database, the entire life cycle of tires can be effectively managed.
10.Intelligent inspection management
The application of RFID technology can realize the electronic, information, and intelligent inspection work, thereby improving work efficiency and ensuring the safe operation of power equipment. It is suitable for users such as enterprises, independent substations and centralized control stations to customize and manage the equipment information, inspection tasks, inspection lines, inspection points, and inspection items involved in the power inspection, to achieve the inspection in-place control and defect management. Standardization, thereby improving the level of power equipment management.
11. Airport baggage management
The application of RFID electronic tag technology to the tracking and management of air parcels ensures that airlines can track, manage and confirm passenger checked baggage, so that passengers and checked baggage can reach their destination safely and on time.
