Abstract

A method and monitoring center for monitoring occurrence of events in a monitored area, where a monitoring equipment displays information that reflects sensor data reported from sensors in the monitored area. When the monitoring center detects an abnormal event, it identifies a set of sensors which are potentially impacted by the event, and triggers the sensors to enter a vigilance state of elevated operation and to deliver enhanced sensor data. Further, a representation of the abnormal event is auto-zoomed on the monitoring equipment based on the enhanced sensor data from the sensors to increase resolution of the displayed representation.

Claims

1. A method performed by a monitoring centre for monitoring occurrence of events in a monitored area, wherein a monitoring equipment displays information that reflects sensor data from sensors distributed in different positions in the monitored area, the method comprising:

detecting an abnormal event in the monitored area based on received sensor data,

identifying a set of sensors potentially impacted by the detected abnormal event,

triggering the set of sensors to enter a vigilance state of elevated operation and to deliver enhanced sensor data,

auto-zooming a representation of the abnormal event being displayed by the monitoring equipment based on the enhanced sensor data from the set of sensors such that resolution of the displayed representation is increased, and

wherein the displayed representation is auto-zoomed gradually over time such that the resolution of the displayed representation is increased in multiple steps.

2. The method according to claim 1, wherein the set of sensors are triggered to enter the vigilance state of elevated operation such that the sensors perform at least one of:

make measurements or observations more frequently,

report sensor data to the monitoring centre more frequently,

increase accuracy of making measurements or observations,

increase accuracy of reporting sensor data,

activate further nearby sensors to also enter the vigilance state of elevated operation to expand the area from which measurements or observations are taken, and

activate a sensor function that was previously sleeping in a sensor with multiple sensor functions.

3. The method according to claim 1, wherein at least one sensor of the set of sensors is triggered to enter the vigilance state of elevated operation by starting to report measurement or observation data periodically to the monitoring centre.

4. The method according to claim 1, wherein at least one sensor of the set of sensors is triggered to enter the vigilance state of elevated operation by changing from inactive to active.

5. The method according to claim 1, wherein auto-zooming the displayed representation comprises at least one of:

focusing and/or enlarging a map image of an area of the abnormal event,

focusing and/or enlarging an infrastructure image of the area of the abnormal event,

focusing and/or enlarging a graph of the enhanced sensor data,

displaying more detailed measurement information,

displaying more detailed location information, and

displaying information about characteristics of the abnormal event.

6. The method according to claim 1, wherein the abnormal event is detected based on historical data that has been stored over time and reflecting previous abnormal events.

7. The method according to claim 1, wherein the enhanced sensor data is used as a basis for determining the nature, location, extent, and/or expected consequences of the abnormal event.

8. The method according to claim 1, further comprising activating at least one complementary mobile sensor to start delivering sensor data to the monitoring centre.

9. A monitoring centre arranged to monitor occurrence of events in a monitored area, wherein a monitoring equipment displays information that reflects sensor data from sensors distributed in different positions in the monitored area, the monitoring centre comprising:

a data collector configured to collect sensor data reported by the sensors,

a logic unit configured to detect an abnormal event in the monitored area based on received sensor data, and to identify a set of sensors potentially impacted by the detected abnormal event,

a triggering unit configured to trigger the set of sensors to enter a vigilance state of elevated operation and to deliver enhanced sensor data,

a display controller configured to auto-zoom a representation of the abnormal event being displayed by the monitoring equipment based on the enhanced sensor data from the set of sensors such that resolution of the displayed representation is increased, and

wherein the display controller is configured to auto-zoom the displayed representation gradually over time such that the resolution of the displayed representation is increased in multiple steps.

10. The monitoring centre according to claim 9, wherein the triggering unit is configured to trigger the set of sensors to enter the vigilance state of elevated operation such that the sensors perform at least one of:

make measurements or observations more frequently,

report sensor data to the monitoring centre more frequently,

increase accuracy of making measurements or observations,

increase accuracy of reporting sensor data,

activate further nearby sensors to also enter the vigilance state of elevated operation to expand the area from which measurements or observations are taken, and

activate a sensor function that was previously sleeping in a sensor with multiple sensor functions.

11. The monitoring centre according to claim 9, wherein the triggering unit is configured to trigger at least one sensor of the set of sensors to enter the vigilance state of elevated operation by starting to report measurement or observation data periodically to the monitoring centre.

12. The monitoring centre according to claim 9, wherein the triggering unit is configured to trigger at least one sensor of the set of sensors to enter the vigilance state of elevated operation by changing from inactive to active.

13. The monitoring centre according to claim 9, wherein auto-zooming the displayed representation comprises at least one of:

focusing and/or enlarging a map image of an area of the abnormal event,

focusing and/or enlarging an infrastructure image of the area of the abnormal event,

focusing and/or enlarging a graph of the enhanced sensor data,

displaying more detailed measurement information,

displaying more detailed location information, and

displaying information about characteristics of the abnormal event.

14. The monitoring centre according to claim 9, wherein the logic unit is configured to detect the abnormal event based on historical data that has been stored over time and reflecting previous abnormal events.

15. The monitoring centre according to claim 9, wherein the logic unit is configured to use the enhanced sensor data as a basis for determining the nature, location, extent, and/or expected consequences of the abnormal event.

16. The monitoring centre according to claim 9, wherein the triggering unit is configured to activate at least one complementary mobile sensor to start delivering sensor data to the monitoring centre.
