BS EN 4817:2012EN 4817:2012 (E) 4 Introduction The requirements for RFID tags to be use
16、d in the aerospace industry are very different from non-aviation uses. The parts identified by the RFID tags are high value items, which are often used for ten years or more. Reading and writing across a moderate distance, and over the life-spans of these tagged-parts, is expected to improve data ac
17、curacy and cost savings. Furthermore, the aerospace industry is subject to unique considerations regarding qualification, regulations, and safety, which are enforced by aviation authorities such as the EASA, FAA, etc. These requirements, coupled with the relatively low manufacturing volumes, will dr
18、ive up the per-part cost of tags developed for the aerospace industry. This will generate the need for a set of RFID tags specifically designed for use on aircraft. Adherence to this European Standard will decrease the development cost of these low-volume, high-capability RFID tags. BS EN 4817:2012E
19、N 4817:2012 (E) 5 1 Scope The scope of this European Standard is to: Provide a requirements document for RFID Tag Manufacturers to produce passive UHF tags for the Aerospace industry. Identify the minimum performance requirements specific to passive UHF tags used on aircraft parts, accessed only dur
20、ing ground operations. Specify the test requirements specific to passive UHF tags for airborne use, in addition to EUROCAE ED-14 / RTCA DO-160 latest issue compliance requirements separately called out in this document. Identify existing standards applicable to passive UHF tags. Provide a qualificat
21、ion standard for passive UHF tags which will use permanently-affixed installation on aircraft and aircraft parts. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

28、TIONS used on products created for the aerospace industry 3.2 AIRBORNE USE used on aircraft while in flightas opposed to Ground Service Equipment, which is used on aircraft, but only while, the aircraft is on the ground 3.3 ATA: AIR TRANSPORT ASSOCIATION airline trade association whose purpose is to
29、 foster a business and regulatory environment that ensures safe and secure air transportation. ATA coordinates standards-creation in support of this purpose. 3.4 BACKSCATTER the Radio Frequency (RF) energy reflected by the tag to transmit information to the interrogator. The RFID tags chip and anten
30、na modulates the incident energy and reflects it back (same orientation but opposite direction). Backscatter is what the interrogator device “reads.” An inert piece of aluminium will reflect RF energy, but in the absence of modulation, it is “reflection”, not “backscatter.” 3.5 BAP Battery Assisted
31、Passive RFID tags that have an on-board battery to power the electronics in the tag, minimizing the power required from the interrogator Radio Frequency Beam. They backscatter like a passive UHF tag only when they are interrogated. BAP tags have greater read ranges than purely passive tags. 3.6 BAR-
32、CODE a standard method of identifying items based on lines of varying widths and spacing that are visually read by a scanner 3.7 BLINK RATE the rate at which an active Chip/Tag sends out s signal to look for, this can be adjusted from hours to seconds depending on the application and desired battery

Department of Defense http:/www.defenselink.mil/.BS EN 4817:2012EN 4817:2012 (E) 7 3.8 CHIP “chip”, or “microchip”, refers to integrated circuits, or ICs. This is the “brain” of the RFID tag. RFID chips modulate reflected RF power to tran
34、smit data back to an RFID reader, or “interrogator”. 3.9 EASA European Aviation Safety Agency 3.10 EIRP Equivalent Isotropically Radiated Power the amount of power that would have to be emitted by an isotropic antenna (that evenly distributes power in all directions and is a theoretical construct) t
35、o produce the peak power density observed in the direction of maximum antenna gain 3.11 EUROCAE European Organisation for Civil Aviation Equipment 3.12 FAA Federal Aviation Administration the airworthiness and aviation authority in the United States of America 3.13 HUMAN-READABLE human-readable refe
36、rs to a representation of information that can be naturally read by humans. In most contexts, the alternative representation is data primarily designed for reading by a machine, e.g., scanner/computer/etc. 3.14 INLAY the RFID inlay is comprised of four primary components: chip, attachment harness, a
37、ntenna, and substrate. An antenna is either laid or printed on a substrate material (typically a polymer). Designers create antenna patterns to satisfy specific performance requirements. The “chip” is harnessed to the antenna pattern so that the contacts on the chip make contact with the appropriate
38、 legs of the antenna. 3.15 INTEGRATED CIRCUIT (IC) see “Chip” 3.16 INTERROGATOR (READER/WRITTER) Radio Frequency device whose purpose is to read data from RFID tags or write data to them. There exist both hand-held versions and desk-top versions. Hand-held interrogators have battery power and on-boa
39、rd modulator/demodulators to allow reading permanently-affixed tags while moving past them, and are usually limited in power output. 3.17 ISO: INTERNATIONAL ORGANIZATION for STANDARDIZATION an international association that manages the process of setting global standards for communications and infor

Other layers and components are often added to provide addition features and performance to the label. 3.19 L
41、RU Line Replaceable Unit a component that can be pulled off the aircraft by “line” mechanics and replaced with an identical part, as opposed to requiring depot-level or manufacturers AOG (Airplane On the Ground) teams to do maintenance in situ 3.20 MACHINE-READABLE the term machine-readable (or comp
42、uter-readable) refers to information encoded in a form which can be read (i.e., scanned/sensed) by a machine/computer and interpreted by the machines hardware and/or software. Machine-readable technologies include optical character recognition (OCR) and barcodes. 3.21 PASSIVE the most common RFID ta
43、gs, in which an interrogator transmits an energy field that “energizes” the tag and provides the power for the tag to backscatter 3.22 RANGE the straight line distance between two articles, e.g., an RFID tag and an RFID interrogator 3.23 RANGE, MINIMUM REQUIRED the minimum distance between the RFID
44、chip and the interrogators antenna that satisfies a requirement for a customers specifications or the performance grades included in this specification 3.24 READER/WRITTER see “Interrogator,” above 3.25 RFID Radio Frequency IDentification a mechanism of applying a unique identifier to an artefact, p
45、lant, person or animal for the purpose of tracking, tracing and locating, using machine readable, non-line of sight technologies. RFID technology provides for non-line of sight creation, modification and deletion of the unique identifier. RF is defined as Radio Frequency, which describes non-line of
46、 sight transmission of data and energy between a radio transmitter/receiver known as an interrogator (reader) and the ID chip that contains the identifier (ID). 3.26 RTCA: RADIO TECHNICAL COMMISSION FOR AERONAUTICS RTCA, Inc. is a private, not-for-profit corporation that develops consensus-based rec
47、ommendations regarding communications, navigation, surveillance, and air traffic management (CNS/ATM) system issues. RTCA functions as a Federal Advisory Committee. 3.27 SCD: SPECIFICATION CONTROL DOCUMENT a requirements document used in lieu of, or in addition to, engineering drawings, and which sp
48、ecifies required performance, physical envelope, and interfaces with adjacent equipment and systems BS EN 4817:2012EN 4817:2012 (E) 9 3.28 SECURITY some minimum level of encoding or password-protecting a data source in order to prevent tampering or inadvertent loss 3.29 TAG RFID tag is comprised of
49、primary components: a RFID inlay, an outer surface (often used for printing), a bonding surface and a specific packaging 3.30 TEMPERATURE, OPERATING the temperature at which the RFID device will normally be interrogated or used 3.31 TEMPERATURE, SURVIVAL the extreme temperatures to which an RFID device will be exposed. The RFID device is not expected to function at these temperatures. 3.32 UHF Ultra-High Frequency (UHF) covers the 300 MHz to 3 GHz frequency band. Passive RFID systems
