The Present Situation And Developing Trend Of RFID



In recent years, the concept of things began to take root, which is following the computer, the Internet and mobile communications after another information industry revolution. The RFID old technology in the Internet of Things opportunity, glow with new technical value, the future of RFID technology in the field of things in the field of development has a pivotal position.

 

Security applications are still mainstream

 

RFID as a non-contact automatic identification technology, which automatically identifies the target through the RF signal and obtain the relevant data, identify the work without human intervention, can work in a variety of harsh environments, High-speed moving objects and can simultaneously identify multiple labels, quick and easy operation.

 

At present, RFID technology is mainly used in channel management, data collection and identity confirmation, vehicle and other objects positioning and other scenes, based on the resulting security, intelligent transportation applications, materials management applications, has been seen in real life everywhere. At present, the application of RFID in the field of security mainly concentrated in the import and export control, burglar alarm, electronic patrol and other security management and several key areas, including import and export control is the most widely used.

 

 

In recent years, the concept of things began to take root, which is following the computer, the Internet and mobile communications after another information industry revolution. The RFID old technology in the Internet of Things opportunity, glow with new technical value, the future of RFID technology in the field of things in the field of development has a pivotal position.

 

 

Access control management

 

Access control management, including personnel and vehicles or items, in fact, is the access to the channel through the identification of personnel or items to determine whether to release and record, and not allowed to access personnel or items to alarm, in order to achieve more stringent management, Our common import and export control, access control, library management, supermarket anti-theft RF card, no charge of the parking management system and so on are channel management.

 

Person and object positioning and automatic management

 

 

The reader is placed in a designated space, on a moving vehicle, on a ship or on an automated assembly line where the RF card is placed on a moving person, item, material, semi-finished product, and finished product. The reader is generally connected to the main message via wireless or wired Management system, the system to read the RF card information to determine the judge to determine the location of people or items and other information to achieve automated management, common applications such as electronic patrol, museum items positioning, prison personnel positioning, mine personnel positioning, production line Automation management, dock items management.

 

 

The future belongs to the Internet of things

 

 

Internet of Things is based on the computer Internet, the use of radio frequency automatic identification, wireless data communications and other technologies to build a world covering everything "Internet of Things", and to achieve the core technology of this matter is RFID. RFID technology development and application, but also from the security to a wider range of areas.

 

To achieve all things connected, we must first of all physical objects that are not intelligent and the Internet linked to the physical world and the Internet must be established between the information channel. In the object network structure system, this part becomes the sensing layer. Things "things" all-encompassing, their size, shape, the environment, the material and movement are all different. Therefore, the technology to achieve the perception layer must meet the relevant requirements: wireless, automatic, reliable, can rely on to absorb the surrounding energy work; its hardware equipment must shape change, size adjustable, simple manufacturing, low prices, can withstand harsh environments. RFID is undoubtedly the best choice. In fact, the US auto-recognition center first proposed Internet of things camera, RFID is regarded as the first choice for sensing technology.

 

RFID as the first prototype of the network used in the perception layer technology, and things have a bond with the Internet. By 2012, almost all in the security, retail, logistics, apparel and pharmaceutical industry and other areas of the Internet of things are uphold the establishment of the United States automatic identification center of the prototype network.

 

In recent years, RFID technology has greatly increased the function of Internet of Things, enriched the connotation of Internet of Things, the development of Internet of things has also promoted the development of RFID technology applications, such as for fresh items, drugs and other "things" on the Internet of Things Special requirements, RFID tags can not only provide the static information of goods, but also provide the location of goods and the surrounding temperature, humidity and other dynamic information, greatly improving the RFID tag changes.

 

 

The economic and social benefits brought by the Internet of Things have been recognized by more and more people. Many countries, enterprises and research institutions have been actively developing and promoting this technology. It is expected that in the next 10 years, in addition to logistics, retail and other areas of the Internet of things will continue to use low-cost simple RFID tags, for environmental information, city information, geographic information, traffic information and other information collection and processing of the Internet of things "Tag", will gradually develop into a CPU, a variety of sensors, GPS locator and other components of small smart devices, and even a dedicated micro-computer.

 

The current use of RFID sensing layer of things has achieved a "human and human" communication and "people and things" communication, but in the future of things to achieve "things and things" communication and interaction, must be installed in the " "The level of" smart "RFID tags. In addition, standardization, interoperability, protocols, regulations and connectivity technologies are still to be improved and improved.
