    Project Project Presentation Transcript

    • Project WorkByRamakrishnan RamanathanRegistration-Nr: 15282054Supervisor: Prof. Dr. -Ing. Jürgen JasperneiteDemonstrator For Near Field Communication(NFC)
    • 21:06:2013| Ramakrishnan Ramanathan – Demonstrator For Near Field Communication..Agenda• Introduction• Motivation.• Proposed Arhitecture• Conclusion and future work.
    • 21:06:2013| Ramakrishnan Ramanathan – Demonstrator For Near Field Communication..IntroductionNear Field Communication(NFC)• NFC is a short range wireless technology based on RFID• NFC operates on 13.56 MHz frequency• Compatible with existing RFID Infrastructure• Range (<= 10 cm theoretical, 1-4 cm typical)• Data transmission rates such as 106kbps, 212kbps, and 424kbps• Setup-time < 0.1 Sec
    • 21:06:2013| Ramakrishnan Ramanathan – Demonstrator For Near Field Communication..NFC Communication Modes• Active device(Initiator): A device that generates its own RF field.Example: NFC enabled mobile and NFC Reader.• Passive Device(Target): A device which uses the RF field created by anactive device. Example: NFC Tag and NFC enabled mobile.• Active Mode : In active communication mode, both devices generate theirown RF field to exchange data.• Passive Mode: In passive communication mode, only one devicegenerates an RF field, while the other uses load modulation to transferdata.
    • 21:06:2013| Ramakrishnan Ramanathan – Demonstrator For Near Field Communication..NFC Operating ModesReader-Writer Mode• An active NFC device reads and writes passive NFC cards/tags.• Tag content: Text, URI (Web Link, Phone Number), Smart Poster.• Applications:-Mobile Coupons-Information access-Smart Posters• Industrial Applications:-Asset Management-Maintenance systems-Product Genealogy [2]Figure 1. NFC Reader/Writer mode [3]
    • 21:06:2013| Ramakrishnan Ramanathan – Demonstrator For Near Field Communication..NFC Operating ModesPeer-To-Peer Mode• Peer-to-peer mode provides easy bidirectional data exchange betweentwo NFC Devices.• P2P mode Provide secure exchange of private data in a few centimeters• Applications :- Health Monitoring [1]- P2P Payment- Bluetooth Pairing• Industrial Applications :- Industrial motor with NFCControl [4]- Automobiles in ignition [5]- Controlling Sensors [6]Figure 2. NFC peer-To-Peer mode [7]
    • 21:06:2013| Ramakrishnan Ramanathan – Demonstrator For Near Field Communication..NFC Operating ModesCard Emulation mode• Tag emulation mode is the reverse of reader/writer mode• In this mode the NFC enabled device acts in passive mode.• A NFC device acts as contactless smartcard and is being recognized byexisting NFC readers• Applications :-Transportation ticketing (Deutsche Bahn)-Contactless logins andauthentication on computers-Payments (Visa pay Wave, Google Wallet)• Industrial Applications :- Access control to Research Labs.Figure 3. NFC Card Emulation mode [3]
    • 21:06:2013| Ramakrishnan Ramanathan – Demonstrator For Near Field Communication..Comparison of NFC and other Short RangeTechnologies
    • 21:06:2013| Ramakrishnan Ramanathan – Demonstrator For Near Field Communication..Localization based Point-of-Information• Localization based Point-of-Information is to gather Information specific toa particular Location.• To get Information we need to browse through the PLC, DCS• Accessing information of one particular small module is sometimes timeconsuming.• Advantages:• Access Real time Information by a simple touch• No Prior Knowledge is required• Information can be obtained in less than a second.
    • 21:06:2013| Ramakrishnan Ramanathan – Demonstrator For Near Field Communication..Continued..
    • 21:06:2013| Ramakrishnan Ramanathan – Demonstrator For Near Field Communication..Interaction sequence
    • 21:06:2013| Ramakrishnan Ramanathan – Demonstrator For Near Field Communication..NFC IN LMFFigure 4.NFC Tag on Plant ModuleFigure 5.Mobile Device displaying the Real Time Information
    • 21:06:2013| Ramakrishnan Ramanathan – Demonstrator For Near Field Communication..Context aware user interface• Why Context aware user interface ?• Information Access From Plug and Play Modules• Less Engineering Effort• Less time Consumption• Overcome Interoperable Issues• Dynamic GUI
    • 21:06:2013| Ramakrishnan Ramanathan – Demonstrator For Near Field Communication..Continued..• Data interchange format – JSON.• Reduces impedance mismatch between database and web server.• Because of the similarity between JSON and JavaScript.
    • 21:06:2013| Ramakrishnan Ramanathan – Demonstrator For Near Field Communication..Proposed Architecture
    • 21:06:2013| Ramakrishnan Ramanathan – Demonstrator For Near Field Communication..Interaction sequence
    • 21:06:2013| Ramakrishnan Ramanathan – Demonstrator For Near Field Communication..Conclusion & Future work• Use Cases of NFC in Industrial Automation is Demonstrated• Advantages:• Accessing localized Real time Information just by a simple touch• Accessing Real time information of Plug & Play Modules.• Future work:• Peer to peer communication of NFC In Industrial automation.• The architecture for generating context aware User interfacedynamically need to be implemented in real life scenario.
