AMR Business Processes
This section describes the utility business processes related to AMR that can be supported through the Oracle Utilities Network Management System MultiSpeak Adapter.
Outage Detection
The vendor AMR system detects no power for a meter, either because of a "last gasp" meter message or from scheduled meter polling. A "power out" call is submitted to Oracle Utilities Network Management System, which generates a probable outage event.
PSO Verification
One customer call is received, generating a probable service outage in Oracle Utilities Network Management System. The Oracle Utilities Network Management System MultiSpeak Adapter is notified of the new probable outage, and the customer meter is pinged to verify power status.
If the meter reports that the power is still on, then we have conflicting information from the customer and the meter, so the outage predication engine will set the status of this event to Verify. At this point, we believe that there is no outage, but that the customer has a problem, such as a blown fuse, within his home. This event must be resolved by a customer service representative contacting the caller to explain the situation to them.
PDO Verification
Several customer calls are received, which are submitted into the Oracle Utilities Network Management System. The resulting probably outage rolls up to a device. The list of affected AMR customers is provided to the Oracle Utilities Network Management System MultiSpeak Adapter by the Oracle Utilities Network Management System outage prediction engine. The interface submits meter status requests to the AMR for any of the affected meters from which it has not already received a last gasp message. The received meter statuses are sent back to the prediction engine and the predicted outage device may change by moving downstream.
Restoration Verification
An outage event is restored in Oracle Utilities Network Management System, and a list of affected meters is provided by the outage prediction engine to the Oracle Utilities Network Management System MultiSpeak Adapter. The interface submits meter status requests to the AMR for any of the affected meters from which it has not received a "power up" message. The results are passed back to the Oracle Utilities Network Management System and the periodic cycle for getting outage events continues. The received meter statuses are sent back to the prediction engine. A power out status will result in another outage call and a nested outage that still needs restoration.
Unsolicited Power Ups
The AMR system can send unsolicited power up message when it detects that meter power has been restored. The adapter delivers such messages to the outage prediction engine, which uses them as part of Restoration Verification processing.
Manual Ping
In the diagram below, please note that the number indicates the sequence of actions:
Urgent Ping
The adapter supports the ability to immediately ping a single meter. Such ping requests are initiated by sending PING high-level message containing single meter id to the adapter. Requests received via high-level message are processed right away without being subject to batching. They do not persist in database. Cache is not used to satisfy such requests so the AMR system is always contacted.
