Radio frequency identification (RFID) technology research and development prospects (1)

At present, RFID has become the it industry's hot topics, considered IT industry in the next "gold".

All major software and hardware vendors, including IBM, Motorola, Philips, TI, Microsoft, Oracle, Sun, BEA, SAP, etc., individual enterprises to RFID technology and its application to demonstrate a keen interest in research and development have been putting in a lot of funding, has launched its own software or hardware products and system solutions.

1. introduction

RFID (Radio Frequency Identification, RFID), also known as the electronic label (E-Tag), is a kind of the RF signal automatically identify the target object and obtain relevant information technologies.

Earliest application of RFID can be traced back to the second world war used to distinguish between Coalition forces and the Nazi enemy aircraft identification "system". As technology advances, growing RFID applications are now available to people in all aspects of daily life and will be the future information society building in one of the foundations of technology. Typical applications include: RFID in logistics field for warehouse management, production automation, commodity sales, in the transport area for container and package management, highway toll and parking; in agriculture and fisheries for the sheep, fish, fruit, management, and pets, wildlife tracking, in the medical industry for drug production, patient care, medical waste tracking; in manufacturing for parts and inventory visibility; RFID can also be applied to the book and document management, access management, positioning and object tracking, environmental awareness, and check the security and many other application areas.

At present, RFID has become the it industry's hot topics, considered IT industry in the next "gold".

All major software and hardware vendors, including IBM, Motorola, Philips, TI, Microsoft, Oracle, Sun, BEA, SAP, etc., individual enterprises to RFID technology and its application to demonstrate a keen interest in research and development have been putting in a lot of funding, has launched its own software or hardware products and system solutions. In the application field to Wal-Mart, UPS, Gillette, represented by the large number of enterprises have already begun preparations for the use of RFID technology on business systems for improvement to improve enterprise productivity and provide customers with a variety of value-added services. In label field, RFID labels and bar codes, have read speed, storage space, working distance, through strong, beautiful and diverse work environment, strong adaptability and reusable, and many other advantages.

Therefore, the analysis of RFID technology status quo and prospects for their future will undoubtedly be very important.

2. research

Current research focused on RFID RFID technology standard, RFID tags, RFID and RFID application systems and other areas.

2.1 RFID technology standards

RFID standardization is an important issue to be solved in the States and relevant international organizations in actively promoting the development of RFID standards.

At present, do not form a perfect regarding RFID's international and domestic standards. RFID standardization involved in identify encoding specifications, operating agreement and application system interface specification, and other parts. Which identifies the encoding specifications include ID length, encoding method, and so on; operation Protocol including air interfaces, command sets, operational processes, and other specifications. Current major RFID related specifications have the EPC standard, Europe and Japan's UID (Ubiquitous ID) specifications and ISO 18000. Which ISO standard main defined tags and readers of interoperability between air interface.

EPC specification by Auto-ID Centre and later founded the EPCglobal develops.

Auto-ID Centre in 1999 by the MIT (MIT) initiated the establishment, its goal is to create a global network of "real Internet" (internet ofthings), the Center received the United States Government and the business community wide support. 2003 October 26, established a new organization to succeed before EPCglobal Auto-ID Center work, management and development of EPC specification. On the label, the EPC specification has enacted the first generation of the criterion.

UID (Ubiquitous ID) specification from Japan ubiquitous ID Center responsible for developing.

Japan ubiquitous ID Center founded by T-Engine Forum, the goal is to establish and promote articles automatic identification technology and eventually build a ubiquitous computing environment. This specification has no mandatory requirements for band, tags and readers are more band equipment, can simultaneously support 13.56MHz or 2.45GHz band. UID label refers to all contain ucode code devices, such as bar code, RFID, smart cards and active chip, and defines nine different types of labels.
