9、ation 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 accuracy and cost savings. Furthermore, the aerospace industr

10、y 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 drive up the per-part cost of tags developed for the aerospac

11、e industry. This will generate the need for a set of RFID tags specifically designed for use on aircraft. Adherence to this standard will decrease the development cost of these low-volume, high-capability RFID tags. 1 Scope / Purpose The scope of this document is to: Provide a requirements document

12、for RFID Tag Manufacturers to produce passive HF tags for the Aerospace industry. Identify the minimum performance requirements specific to passive HF tags used on aircraft parts, accessed only during ground operations. Specify the test requirements specific to passive HF tags for airborne use, in a

13、ddition to EUROCAE ED 14 / RTCA DO-160 latest issue compliance requirements separately called out in this document. Identify existing standards applicable to passive HF tags. Provide a qualification standard for passive HF tags which will use permanently-affixed installation on aircraft and aircraft

14、 parts. 2 Normative references The following publications form a part of this document to the extent specified herein. The applicable issue of other publications shall be the issue in effect on the date of manufacture. In the event of conflict between the text of this document and references cited h

15、erein, the text of this document takes precedence. Nothing in this document, however, supersedes applicable laws and regulations unless a specific exemption has been obtained.

20、ACE APPLICATIONS 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 pu

21、rpose is to 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 chi

22、p and antenna 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 Batter

23、y Assisted 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 tag

26、om hours to seconds depending on the application and desired battery life of the RFID tag 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 transmit data back to an RFID reader, or “interrogator”. 3.

In most contexts, the alternative representation is data primarily designed for reading by a machine, e.g., scann

30、er/computer/etc. 3.16 INLAY the RFID inlay is comprised of four primary components: chip, attachment harness, antenna, 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. Th

31、e “chip” is harnessed to the antenna pattern so that the contacts on the chip make contact with the appropriate legs of the antenna. 3.17 INTEGRATED CIRCUIT (IC) see “Chip” prEN 4818:2011 (E) 6 3.18 INTERROGATOR (READER/WRITTER) Radio Frequency device whose purpose is to read data from RFID tags or

32、write data to them. There exist both hand-held versions and desk-top versions. Hand-held interrogators have battery power and on-board modulator/demodulators to allow reading permanently-affixed tags while moving past them, and are usually limited in power output. 3.19 ISO: INTERNATIONAL ORGANIZATIO

33、N for STANDARDIZATION an international association that manages the process of setting global standards for communications and information exchange 3.20 LABEL label is comprised of three primary components: an RFID inlay, an outer surface (often used for printing), and a bonding surface. Other layer

34、s and components are often added to provide addition features and performance to the label. 3.21 LRU 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 th

35、e ground) teams to do maintenance in situ 3.22 MACHINE-READABLE the term machine-readable (or computer-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 technolog

36、ies include optical character recognition (OCR) and barcodes. 3.23 PASSIVE the most common RFID tags, in which a interrogator transmits an energy field that “energizes” the tag and provides the power for the tag to backscatter 3.24 RANGE the straight line distance between two articles, e.g., an RFID

37、 tag and an RFID interrogator 3.25 RANGE, MINIMUM REQUIRED the minimum distance between the RFID chip and the interrogators antenna that satisfies a requirement for a customers specifications or the performance grades included in this specification 3.26 READER/WRITTER see “Interrogator,” above 3.27

38、RFID Radio Frequency IDentification a mechanism of applying a unique identifier to an artefact, plant, 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

39、 deletion of the unique identifier. RF is defined as Radio Frequency, which describes non-line of 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). prEN 4818:2011 (E) 7 3.28 RTCA: RADIO TECH

48、 runways. 5 General configuration RFID tag consists of a chip (integrated circuit), attached to an antenna, both of which are mounted on a dielectric substrate. The tag shall include identification markings, and shall have a cover layer that can be written on, or to which adhesive labels may be appl
