Application status and development trend of RFID
In recent years, the concept of the Internet of Things has begun to take root, which is another revolution in the information industry following computer, Internet and mobile communications. The old technology of RFID has a new technological value in the opportunity of the Internet of Things. In the future, RFID technology will play a pivotal role in the development of the Internet of Things.
Security applications are still mainstream
As a non-contact automatic identification technology, Radio Frequency Identification (RFID) automatically recognizes target objects and acquires relevant data through radio frequency signals. The identification work can be performed in various harsh environments without human intervention. High-speed moving objects and multiple labels at the same time, quick and easy operation.
At present, RFID technology is mainly used in scenes such as channel management, data acquisition and identity confirmation, and vehicle positioning, etc. Based on the applications of security prevention, intelligent traffic application, material management, etc., it has been seen everywhere in real life. At present, the application of RFID in the security field mainly focuses on several key areas such as entrance and exit control, burglar alarm, electronic patrol and other security management. Among them, entrance and exit control is the most widely used.
Channel management includes personnel and vehicles or articles. In fact, it is the identification and confirmation of persons or articles in and out of the access passage to determine whether they are released and recorded. At the same time, the people or articles that are not allowed to be allowed to be warned to achieve more strict management, we often see the entry and exit control, entrance control, and library management. Management, supermarket anti theft radio frequency card, and no charge parking lot management system are all channel management.
Human and material location and automation management
The reader is placed in a designated space, on a moving vehicle, on a ship, or in an automated assembly line. The RF card is placed on a moving person, item, material, semi-finished product, or finished product. The reader is generally connected to the main information by wireless or wired. Management system, the system analyzes and judges the information of reading radio frequency card, determines the location and other information of people or items, and realizes automatic management. Common applications such as electronic patrol, museum item positioning, prison personnel positioning, mine personnel positioning, production line Automated management, terminal item management, etc.
The future belongs to the IOT (Internet of things)
The Internet of things is based on the computer Internet, using radio frequency automatic identification, wireless data communication and other technologies to build a “Internet of Things” covering all things in the world, and the core technology to achieve this kind of combination is RFID. The development and application of RFID technology also extends from security to a wider field.
As the first sensing technology used in the Internet of Things, RFID has an indissoluble bond with the Internet of Things. By 2012, almost all of the Internet of Things established in the security, retail, logistics, apparel, and pharmaceutical industries will inherit the prototype Internet of Things established by the above-mentioned US Automatic Identification Center.
At present, the Internet of Things with RFID sensing layer has realized “human-to-human” communication and “human-to-material” communication, but in order to realize “material-to-material” communication and interaction in the future Internet of Things, it must be upgraded to “Intelligent level of RFID tags that make “things” intelligent. In addition, standardization, interoperability, protocols, regulations, and connectivity technologies still need to be improved and improved.
