First, data for each viewpoint may be generated based on the first data (step S210). A time point serving as a criterion for generating data for each time point may be arbitrarily selected. For example, data for each time point may be generated every hour. The first data generated by the air purifier (100 in FIG. 1 ) may include dust concentration and information on whether the air purifier is operating. The service server (200 in FIG. 1 ) converts the average value of the dust concentration of the first data generated (or received) between 4:00 and 5:00 and information indicating whether the air purifier is operating at 5:00 as 5:00 data. can be created and saved. The service server ( 200 in FIG. 1 ) may generate hourly data for each of the plurality of air purifiers in the same manner and store the generated hourly data in association with a unique number of each of the plurality of air purifiers.

Next, minimum driving data may be collected based on data for each time point (step S220).

For example, the service server determines that the maximum value of the dust concentration during the unit time (eg, 1 day) is less than or equal to the reference value based on the data for each time point during the unit time (eg, 1 day), and the unit time Data in which the driving time for (eg, 1 day) is equal to or longer than the reference time (eg, 12 hours) may be collected as the minimum driving data.

In this case, there may be a plurality of dust concentrations for each size of dust, and the service server may collect data in which all of the plurality of dust concentrations are equal to or less than a reference value as minimum driving data.

The air purifier 100 , the mobile terminal 300 , or the user terminal 400 may also collect driving data while cooking in a manner similar to that described above.

As described above, the present invention has been described with reference to the drawings illustrated, but the present invention is not limited by the embodiments and drawings disclosed in this specification, and various modifications are made by those skilled in the art within the scope of the technical idea of the present invention. It is obvious that variations can be made. In addition, although the operational effects according to the configuration of the present invention have not been explicitly described and described while describing the embodiments of the present invention, it is natural that the effects predictable by the corresponding configuration should also be recognized.
