  1. SENSORS and PUCK Duane Edgington, Bob Herlien, Kevin Gomes, Tom O’Reilly MBARI

  2. Outline • SENSORS Project Overview and Goals • Prototyping • ALOHA Opportunity • PUCK Overview • PUCK with SENSORS and MARS • CI Prototyping

  3. SENSORS Project Overview And Goals • NSF 0330428: Ocean Observing System Instrument Network Interface • Goal: identify and analyze software ‘middleware’ requirements for OOI (MARS) observatories as first step in standardizing instrument middleware interfaces to system and shore • Requirements workshop held in 2004 • Prototyping SIAM and SSDS on MARS instruments • Test SIAM and SSDS on MARS with dedicated test instrument when MARS deploys • Report results and offer technology to OOI

  4. Prototyping • Test workshop results • SIAM middleware already working on MOOS • Test directly on MARS • CTD to deploy with Node • ALOHA, EITS

  5. ALOHA Opportunity • The ALOHA - MARS mooring sensor networkcombines adaptive sampling methods with a moored deep-ocean sensor network.

  6. ALOHA Opportunity • We engaged ALOHA - MARS team December 2006 to offer our instrument interface and data management technology for ALOHA - MARS mooring deployment on MARS • MBARI supplied SIAM services and SSDS interfaces for two instruments: • CTD: SeaBird SBE-52MP • Scattering/Fluorometer: Wetlabs ECO-BB

  9. PUCK Overview • PUCK is fundamentally a protocol

  10. PUCK payload PUCK payload How does it work? • Technology to store instrument-related information with the instrument itself RS-232 instrument PUCK Observing system retrieves and utilizes information through instrument’s serial interface, using MBARI PUCK protocol “Plug-and-Work”

  11. Sensors Networks and PUCK • Installation and configuration • Observatory retrieves info from PUCK, automatically configures itself to accommodate the instrument and its data • Diversity of instrument protocols • PUCK can store “instrument driver” code that is retrieved and executed by observatory host; no need for host to know instrument protocol a priori • Association of instrument data with metadata • Preloading instrument with metadata prior to deployment helps ensure that metadata is correctly associated with instrument; observatory gets metadata from the instrument itself.

  12. PUCK Application: JDDAC • Environmental sensor network deployed in San Francisco Bay; developed by SFSU and Agilent (non-MBARI system) • Based on IEEE 1451.x Smart Transducer standards

  13. TEDS TEDS TEDS Standard JDDAC Measurement Raw data JDDAC IEEE-1451 environmental sensor network Network Agilent server Plots, statistics, etc can be generated from standard measurements JDDAC “probes” We modified JDDAC probe software to retrieve TEDS from PUCK Implemented prototype in about one week for JavaOne

  16. PUCK and the Oceanographic Community • Awarded US patent, 2005 – protects standard protocol • Royalty-free license available to instrument manufacturers • No restrictions at all for PUCK users • Website at www.mbari.org/pw • Technical documents, PUCK toolkit, reference implementation – free download • Includes Marine Plug-and-Work Forum; ~80 potential users and implementers signed up • Marine plug-and-work consortium • Proposed as a mechanism to move technology forward • Explore alternate technologies; PUCK is but one solution; consortium could explore others • Users and vendors would run consortium
