The fire detection server 300 is a server for recognizing a fire related situation in a ubiquitous environment and intelligently analyzes the status information collected by the sensor module 100 and the power consumption data collected by the digital power measurement module 200 do. The fire detection server 300 can predict and predict a fire situation by storing and updating various environmental factors or situations in which a fire can occur, and by analyzing collected status information or patterns of collected power consumption data.

The fire detection server 300 includes a context-aware manager 310 and a control manager 320. The situation recognition manager 310 collects and analyzes the fire related environmental information sensed by the fire sensor of the sensor module 100 to recognize the possibility of fire occurrence (i.e., a situation) with respect to the peripheral position of the fire sensor, It is possible to deduce and determine the appropriate service corresponding to the perceived fire incidence.

In addition, the situation awareness manager 310 may analyze the power consumption data received from the digital power measurement module 200 to recognize the possibility of occurrence of an overcurrent. The context aware manager 310 analyzes power consumption data previously received from the digital power measurement module 200 to generate a power consumption pattern, compares the generated power consumption pattern with the currently received power consumption data, Or the possibility of occurrence of an overcurrent can be recognized.

The analyzed environment information may be provided to the learning engine 312 and the situation inferring unit 313. The situation analyzer 311 may analyze the power consumption data measured from the digital power measurement module 200 and provide the analyzed result to the learning engine 312 and the situation inferring unit 313. [

Situations can be recognized through learning. The learning engine 312 can receive environment information or power consumption data analyzed in real time or periodically from the situation analyzer 311 and use it for fire prevention learning.

The learning engine 312 may be aware of the situation through learning or data mining techniques. That is, the learning engine 312 compares accumulated environmental information, that is, past environmental information with currently collected environmental information, to predict whether the probability of occurrence of a fire is high. Also, the learning engine 312 can compare the accumulated power consumption data of the past with the currently measured power consumption data to predict the possibility of occurrence of a fire.

Or, the situation may be perceived through reasoning (abstraction, reasoning). The situation inferring unit 313 can infer the state of the surrounding environment in which the sensor is installed, that is, the situation related to the fire occurrence, using the analyzed environment information provided from the situation analyzing unit 311.

In addition, the rule and situation data management unit 314 can record and manage the occurrence of an overcurrent generated in response to power consumption data from past to present, whether or not a fire has occurred, and the like.

The rule engine 315 may create a rule or pattern corresponding to the context by reasoning. A rule or pattern may be the result of a context perception around the sensor that sensed the environment information or a result of the context of the device. The perceived results are the result of a fire or an overcurrent.

The service determination engine 316 may determine a service corresponding to a rule or pattern created in the rule engine 315.

The integrated interface unit 321 may receive power consumption data of the device measured from the digital power measurement module 200. [ The integrated interface unit 321 and the power measurement unit 220 of the digital power measurement module 200 may be connected by wire or wireless communication. The integrated interface unit 321 provides the power consumption data of the received device to the situation awareness manager 310.

The administrator can more accurately confirm the current state of each device through the information displayed on the display unit 322. [

If the service determined by the service determination engine 316 determines the possibility of occurrence of an overcurrent, the power control unit 323 controls the digital power measurement module 200).
