Primate's BlackBoard™ and GridGuardian™ servers aggregate events and other data from different sources. The last-known-good values for these events and data items are cached within the server. TileViewer™, a BlackBoard client viewer application, displays last known good values in near real time. The Primate Replay Server allows an authorized user to go back in time – to a specific window, as desired -- to review the historical events of data visually, regardless of the source of the data.
With Replay, study cases can be saved for trainers to train operators. Alternatively, operators may choose to perform a post-event analysis and review, such as after a major storm. During shift changes, operators may also want to visually review important events from the previous shift. All events and other data are stored in such a way that it can easily be retrieved for later replay, including events from SCADA/EMS/(A)DMS/OMS, pins, notes, tags, TileViewer drawing tool objects, Automatic Vehicle Location (AVL) data, and weather radar/lightning/alerts.
Replay records events constantly. There is no need to start and stop recording. When a configurable disk space quota is reached, older historical data is purged from the database, allowing space for the newest events and data. Saved study cases are separately stored and do not get purged.
During a replay, the user has the ability to select the desired replay time interval and replay speed. The Primate replay application pushes the historical data to BlackBoard’s TileViewer client, to be viewed on the current display map. All the normal, view-only TileViewer display features are available during historical data replay (pan, zoom, find or search information, toggle layers, view description of pins and notes, etc.).
Because the raw data is stored, the data may be replayed against any display, even a new display built after an incident. For example, if the customer has a geographic and a schematic display, the historical data can be replayed in any display. This could be used to give different views into the same historical timeline.
The TileViewer user interface provides the ability to bookmark a specific point in time in the historical data. This allows the user to quickly replay a session beginning at the defined bookmark.
When TileViewer is in replay mode, it presents an orange border, and a replay timestamp at the top of the display helps clearly distinguish the replay window from a window receiving real-time updates.
When replay is running, TileViewer will display the sequence of actions that have occurred between the replay begin timestamp and the replay end timestamp. Replay setting parameters can be adjusted to play back history at a faster or slower rate than events happened originally.
