RFID英文綜述

1、Radio Frequency Identification Overview IntroductionWith the development of Internet technology, Internet-based expansion and extension form a new generation of network technology that is of things.The so-called Internet of Things, also known as sensor networks, the English name is "Internet of

2、 Things" referred to (IOT.Internet of Things is a computer based on the use of radio frequency identification technology, wireless communication technology, infrared sensors, global positioning systems, laser scanners and other information sensing device, according to the agreed protocol to con

3、nect to any goods and the Internet, exchange of information and communication, in order to achieve intelligent identification, location tracking, monitoring and management of a network.SummaryInternet of Things technology is the most critical of RFID technology.RFID is the abbreviation of Radio Freq

4、uency Identification. It is a non-contact automatic identification technology, RF signal through the automatic target recognition and access to relevant data, without human intervention, it can work in a variety of environments.First RFID components and working principleRadio frequency identificatio

5、n system consists of electronic tags, reader, antenna composition.Tag: the coupling components and chips, each tag has a unique electronic code, attached to the object on the target object.Reader: Also known as the read set, can be read without contact and identification tag in the preservation of e

6、lectronic data, so as to achieve automatic ten-fold purpose of the object, there are two kinds of hand-held or fixed, usually with a computer reader connected to the read tag information is transmitted to the computer for further processing.antenna :Tag and reader antennas in the RF signal to pass b

7、etween antenna.Second RFID applicationsRadio frequency identification technology with its unique advantages, gradually been widely used in industrial automation, business automation and transport control management.In China, due to radio frequency identification technology started late, RFID is not

8、very wide applicated, in the following areas:(1 automatic vehicle identification, as early as 1995, the North American rail system used radio frequency identification technology ATIS standard. (2 fees and intelligent traffic on the highway, the car can be equipped with automatic radio frequency iden

9、tification tags, no parking fee, which greatly improve the speed and efficiency.(3 cargo tracking, management and monitoring, Australia and the UK airport used radio frequency identification technology in baggage management, which greatly improve the efficiency of sorting andreduced the error rate.(

10、4 radio card applications in China, mainly used in RF card public transport, subways, schools, social security and so on. China RF card application largest project is the second generation citizen ID card. (5 in the production line automation and process control, the German company BMW car assembly

11、line to ensure the accuracy of the position to complete the assembly task, the radio frequency identification system used in automobile assembly line.Third Development problems faced by RFID technology (1 privacy issuesIn RFID systems, tags could be embedded in anything in advance, such as people

12、9;s daily life items, but because the items (such as clothing of the owner, not necessarily aware of the article pre-embedded in an electronic tag and its own may not be controlled by scanning, positioning and tracking, which is bound to make the issue of personal privacy have been violated.Therefor

13、e, how to ensure the label material with the inviolability of personal privacy become a radio frequency identification technology as well as things to promote the key issues.(2 standardsChina made no introduction of RFID standards, the rapid development of the domestic RFID industry in China is not

14、in accordance with the standard, causing confusion in product standards, greatly reduces the international competitiveness(3 security issuesCurrent Things security issues face the industry including the tag information of illegal changes to the label's illegal to track effectively the identity o

15、f pretending and deception.(4 market demandSome things look very convenient service, but in both cases, whether people have an incentive to use these new services yet to be questionable. Fourth RFID TrendsAs RFID technology continues to promote the development and application of the popularity of ra

16、dio frequency identification technology and other aspects of performance will have improved greatly, the cost will be gradually reduced, can foresee the future development of RFID technology will have the following trends:(1 label product diversification.(2 system network.(3 a better system compatibility(4 integration
