23、2015(E) Introduction This part of ISO/IEC 18046 covers test methods for the performance of HF RFID gates in libraries. The term HF RFID gate refers to an HF RFID interrogator that supports an arrangement of several HF RFID antennas utilizing multiplexers or splitters. Antenna pairs are usually place

24、d on opposite sides of a so- called passage way through which tags are moved and captured. The positioning of such HF RFID gates at entrances, exits and transit positions within buildings thus permits the capturing of access and/or outward movement of objects/media or media stacks. At the same time,

25、 the possibility of stack (bundle) detection permits the simultaneous recognition of several tags. HF RFID gates are available as permanently installed or mobile variants. The reading range of HF RFID gates is limited but can be set in the range of 0,5 m to 2 m for 13,56 MHz (inductive coupling) sys

26、tems based on the size and number of antennas and/or of the tag properties. The main purpose of the gates within a library lies in anti-theft protection of media using simple reading of security bits (AFI or EAS) on a tag. Aside from that, they also permit the capturing of the specific medium by rea

27、ding out extended information that can be additionally stored in a tag. There are also hybrid systems, which additionally allow capturing of so-called EAS magnetic strips. HF RFID gates within libraries are frequently used in combination with visitor counters (e.g. light barriers) which permit direc

28、tion-dependent capturing of gate use. These visitor counters can be installed optionally or can alternatively be a fixed part of the gate. Current gates can recognize tags in horizontal and vertical as well as diagonal positions. A few possess auto-tuning functions that automatically correct the mag

29、netic field if there is a drop in performance. The selected operating mode (AFI) is constant throughout the entire individual tests. Figure 1 shows four essential processes that could be identified for HF RFID gates in libraries. These are, on the one hand, the registration of media security at the

30、time of access/outward movement of objects and therewith the alarm functions. Then, there is the pure detection of media information of the tags that have been moved. Furthermore, there is the optional counting of visitors and finally, the communication with the backend systems of the library, thoug

31、h this is not compulsory. In its main function of media security, a gate should also function offline. Figure 1 Typical process flow at a gate By increasing service demands in the area of opening times and increasing cost pressures at the same time, public and academic libraries increasingly rely on

32、 the use of automated accounting systems based on radio frequency technology. In addition to posting the media for lending and return, the technology also provides an anti-theft device. Core components for preventing burglary are sensor systems, which vi ISO/IEC 2015 All rights reservedBS ISO/IEC 18

33、046-4:2015ISO/IEC 18046-4:2015(E) are installed in the form of pass gates at the entry and exit. Prior to this part of ISO/IEC 18046, there were no requirements and test specifications that describe the performance of these sensor systems uniformly. With the present test methods for standardization

34、of performance evaluation of HF RFID gates for use in libraries, this gap will be closed. The RFID performance of the gates can be impaired if objects that have an influence on the magnetic fields are present in the direct vicinity of the gates. Materials such as metals, water and substances with a

35、high density can influence transmission here. In libraries, it is mostly due to constructional and/or architectural reasons that such objects are present in the direct vicinity of HF RFID gates. These can be metallic door frames, staircase railings, floor heating as well as sign plates or metallic f

36、urniture. In many cases, it is not possible to maintain a minimum distance, resulting in possible performance losses of the antennas. Special influence is also exerted by power lines with high output or lines with power line telecommunication within the building which are laid into the floor or in t

37、he walls and are not visually identifiable as sources of interference. Influences can be caused by active and passive sources. These include the RFID components themselves. The passive sources of interference include all kinds of furniture of a library composed of or containing metal which can possi

38、bly have an interfering influence and can distort the detection field. This also includes tags disposed in the vicinity of the gates which are positioned in a secured variant within the library. All kinds of electrical devices and machines that can exert an electro-magnetic influence on the gate in

39、libraries, and/or buildings, in general, can be summed up as active interferers. In this part of ISO/IEC 18046, references to HF RFID gates, interrogators, and tags usually assume HF RFID gates, HF interrogators, and HF tags.
