How RFID technology has become the promoter of the intelligent industry
The Internet of Things information is no longer strange, and RFID technology has become an important perception layer of the Internet of Things. In this era of Internet of Things, RFID technology is one of the key technologies for data connection and data exchange. Before understanding RFID technology, we must first understand the composition of RFID. RFID systems include: electronic tags (TAG), readers (Reader) and computers and their application software. Among them, the main function of the electronic tag is to complete communication with the RF antenna; the main function of the reader is to read or write the information of the electronic tag; the function of the computer and application software is to connect an external meter through the communication interface of the reader Computer, or connect to the host computer host system, so as to realize the exchange of data.
RFID technology is also called radio frequency identification technology. It is a communication technology that uses radio signals to identify specific targets and read and write related data without establishing mechanical or optical contact between the identification system and the specific targets. Compared with the bar code technology, which is also the representative of information recognition technology, RFID has more advantages and broader prospects, and is now widely used in various industries.
1. Batch reading
In terms of information reading, RFID does not need to be visible, nor does it ignore the obstruction of objects. It only needs to complete the reading and writing of RFID data within the scope of the RFID reader. RFID also has the advantage of reading large amounts of data. It can quickly read more than thousands of RFID tag data information at a time, with extremely high efficiency.
2. Flexible form
RFID electronic tags can be made into different shapes and sizes, without the need to use fixed materials and attachment methods for accurate reading. Nowadays with the advancement of technology, more compact and unique RFID tags have been introduced to meet the information recognition needs of different types of industries and products.
3 Wide reading range
The reading range of RFID data information can be increased to different degrees according to the power of the reader and the antenna, and can achieve accurate reading within a range of ten meters, which has more range advantages than traditional identification technology.
4. High security
The RFID tag can encrypt the information of the chip, and the RFID tag is unique and cannot be copied. By writing specific information on RFID tags and binding them with articles, it can play a role of anti-counterfeiting and effectively prevent the appearance of counterfeit and shoddy products.
5. Long-term durability
RFID has the characteristics of waterproof, anti-alcohol, anti-corrosion, anti-magnetic, high temperature resistance, anti-pollution, etc., and can maintain normal work in harsh environments. And different RFID tags, the information can be stored for several years to several decades, very durable.
6. Data storage
The capacity of one-dimensional bar code is 50Bytes, the maximum capacity of two-dimensional bar code can store 2953Bytes, the maximum capacity of RFID is a few MegaBytes. With the development of memory carriers, the capacity of data storage is also expanding. RFID can also repeatedly add, modify, and delete the data stored in the RFID tag to facilitate the update of information.
The carrier of RFID technology generally has the characteristics of waterproof, anti-magnetic, high temperature resistance, etc., which ensures the stability of the application of radio frequency identification technology. RFID technology has advantages in real-time data update, information storage, service life, work efficiency, security and so on. On the premise of reducing manpower, material resources, and financial resources, RFID can update existing data more conveniently and make work more convenient. RFID technology stores information according to computers and the like, up to several megabytes, and can store a large amount of information to ensure the smooth progress of the work. RFID technology has a long service life, as long as the staff pays attention to protection, it can be reused.
With the rapid development of next-generation high-tech technologies such as the Internet of Things, big data, cloud computing, artificial intelligence, and 5G, RFID technology has also experienced unprecedented development. RFID technology has changed the inconvenience of information processing in the past, realized multi-target simultaneous recognition, and greatly improved work efficiency; electronic tags have unique codes, are not easy to forge, and have high security. RFID technology has been recognized and used in many fields. It is believed that in the near future, RFID technology will penetrate into all aspects of people's daily life and work, bring greater social and economic benefits, and make our lives better.
