MBARI Observatory Software Software Infrastructure and Applications for MOOS K. Headley January 2011

MOOS System Concept

MARS Cabled Observatory

Key System Concepts Reliability Flexibility –Moored systems –Cabled observatories Scalability –Resource constrained/rich –Many platforms, many instruments Interoperability –Platform-to-platform –System-to-system Capability –Real-time (or nearly so) telemetry and control –Event Detection

Instrument Integration Mostly serial instruments COTS and custom Proprietary protocols –Control, data formats Spectrum of machine/human friendliness Unfavorable economics for interface standards

Between the sensor and scientist’s eye… Instrument firmware, protocols Platform Middleware (e.g. SIAM) Data Handling System (e.g. SSDS) Standard Interfaces Proprietary Interfaces Standards Middleware Clients IEEE1451 OGC SWE ESB/GRID OSDT Vendor Custom … Observatory Implementers Instrument vendors Standards Gap

SIAM Functions Data Acquisition –accurate time, but not hard RT (maybe should be) –connected, not connected Local data archive Telemetry, delivery to SSDS Resource management –energy, bandwidth, data storage System diagnostics Event detection...

SIAM Features Flexible architecture –Distributed, Scaleable, Interoperable –Plug-and-Work, PUCK compatible –Operable across different resource regimes –Field upgradeable Instrument Service Framework –Ease instrument integration –Uniform network instrument interface –Modular, stand-alone –Open, extensible –Provides facilities for logging, time-stamping, resource management, data summarization –Polled, streaming instruments –Abstractions for communications/power ports, data logs –Custom hooks for platform-specific hardware

PUCK and SIAM SIAM Host SIAM Payload Service XML Instrument service Service Properties Load and run service Pass service XML to data system Use service properties to configure instrument SSDS

Plug and Work: Moored System TCP/IP, PPP SSDS Portal (SIAM Client) BIN SIAM in situ SIAM Uses PUCK to configure Platform, sampling, telemetry Low Bandwidth: SIAM Proxy forwards full/summarized data to data system SIAM Remote or Local Control SIAM

Plug and Work: Cabled Observatories SIAM Virtual Serial Port Eth-Serial Adapter TCP/IP MARS Node SSDS SIAM On Shore Configures and control via virtual serial port No Host Environment: Power and Data Only Control via Network High Bandwidth, No Proxy: Data published directly to data system
