Manage remote and directly connected marine platforms as collections of instruments, physical devices and associated platform resources. Management includes control, monitoring, and event notification.
- Platform is capable of being managed by the Integrated Observatory (i.e., is commandable).
- For intermittently connected platforms, monitoring and commanding the platform can occur without the platform connected directly via satellite.
Platform operational and connects (at least intermittently) to the shore.
- Marine Observatory Operator inspects platform resource status and levels
- These are defined as those resources that specifically address platform capabilities. (They are provided and measured by engineering systems and instruments on the platform.)
- Resources include power, onboard data storage, CPU load, memory usage, and communication bandwidth.
- There may be additional relevant status items to display.
- Marine Observatory Operator inspects status messages for platform
- Marine Observatory Operator has ready access to time-tagged platform error/warning/info/debug messages.
- Again, these are the messages from the platform resources.
- <3> Marine Observatory Operator inspects overview of status indicators for platform connected instruments
- Status overview indicates basic status categories for principal functions (power, command, data, ...)
- <3> Marine Observatory Operator inspects overview of all platform instrument/driver/agent statuses.
- Display list of all instruments installed on platform
- For each, display summary items like ID#, name, port, agent/driver state, sampling status, counts of info/warning/alarm notifications, time since last communication
- Marine Observatory Operator has ready access to time-tagged instrument info/warning/alarm/debug messages
- Marine Observatory Operator commands platform assets, including (in some cases) power supplied to instrument ports.
- These are the assets providing platform capabilities, like communications, power, computing, and location and time sensing.
- Platform may have control over power for individual instruments or sub-platforms, via the power ports the platform can control.
- Marine Observatory Operator can monitor and command specific instruments on the platform
- Marine Observatory Operator receives asynchronous notification of a platform fault
- Important messages (such as faults) are propagated from agent/driver to user, even over intermittent network links (e.g. satellite link)
- <3> Marine Observatory Operator views summary of telemetry received from platform
- Includes age since last communication and/or data sample; increasing stream age indicates possible fault in instrument, platform, communication link, or other subsystem
- Marine Observatory Operator can ideally view history of instrument error sampling rates
- For intermittently connected platforms, Marine Observatory Operator can request immediate establishment of satellite connection to the platform
- Obtaining a connection is not guaranteed (the platform may be freely mobile under water, for example).
- This connection then enables direct platform and instrument access (see UC.R2.07 Direct Instrument Access)
- The establishment of the connection could lead to update of status and events from the platform as a side effect, depending on communications designs.
- Marine Observatory Operator can modify the platform configuration that describes the installed systems.
- This capability supports operational replacement, addition, or deprecation of deployed instruments.
- Parts of this may not be supported through a user interface.
- Marine Observatory Operator can modify the platform's operational configuration.
- This capability supports modifications to the operations of the platform-supporting instruments.
- Includes telemetry schedule for platform-supporting instruments.
Platform configuration and systems updated or scheduled for update with next communication interval.
