Hi all,<br>i am going to use a custom accumulate function like that:<br><br>rule "CrowdInAreaEvent-event"<br> no-loop<br> when<br> $RFIDReader : SensorFixed(type == Sensor.SENSOR_TYPE_RFID, $coverageArea : areaOfInterest )<br>
not CrowdInAreaEvent( sensor == $RFIDReader, this meets[ 5s ] $obs )<br> $count : Integer( intValue > 10 ) <br> from accumulate(<span style="color:rgb(255,0,0)"> $obs : </span>RFIDObservation( $tagid : tagid, sensor == $RFIDReader ) <br>
over window:time( 60s ) from entry-point lowLevelSensorStream, countDistinct( $tagid ) );<br> then<br> insert( SituationManager.createCrowdInAreaEvent( "Crowd, number people: " + $count, Event.THREAT_LOW, $coverageArea, $RFIDReader, $count, 60, 10 ) );<br>
end<br><br>I need to refer $obs object in order to compare timing of new observation with last event. Is it possible to do that?<br><br>Thanks a lot,<br>Matteo.<br>
