  Next, in step 104, the control device 12 determines whether or not the power consumption is abnormal. For this determination, for example, an average value of power consumption stored in the device monitor result DB 56 is calculated, and consumption equal to or higher than a predetermined threshold (abnormal power increase rate threshold value stored as the outlet DB 54) with respect to the calculated average value. It is determined whether there is an increase in power, or, as shown by the dotted line range in FIG. 6, it is determined whether there is an increase in power consumption at a change point that is greater than or equal to a predetermined slope. If yes, the process proceeds to step 106, and if not, the process proceeds to step 114.

  In step 106, the control device 12 notifies the electric device corresponding to the power consumption abnormality, and the information is stored in the HDD 46, and the process proceeds to step 108. That is, the control device 12 identifies the electrical device 14 corresponding to the power sensor 28 in which the power consumption abnormality is detected from the outlet DB 54, and displays on the display unit 40 that the identified electrical device 14 has a life or abnormality. In addition, the HDD 46 stores information indicating that the electric device has a life or abnormality. Thereby, it is possible to notify the resident of the existence of the electric device 14 in which the life or abnormality has occurred. In addition, as a notification method, you may make it alert | report by an audio | voice other than displaying on the display part 40, or providing a warning lamp etc. and alert | reporting. Further, it is possible to notify the information at a predetermined timing without storing the information immediately, and to notify the abnormality at a predetermined timing. Alternatively, the resident can access the HDD 46 by operating the operation unit 42 or the like without notification. By doing so, the life and abnormality of the electric device 14 can be known, so that a configuration not informing may be adopted.

  In step 108, the control device 12 searches for an electric device of the same type as that of the electric device 14 determined to have a life or an abnormality and is installed at the same time. That is, by searching the outlet DB 54 stored in the HDD 46, the same type and simultaneous installation as that of the electrical device 14 having a life or abnormality is searched.

  In step 110, it is determined by the control device 12 whether there is an electric device 14 to be searched. If the determination is negative, the process proceeds to step 114, and if the determination is affirmative, the process proceeds to step 12.

  In step 112, it is notified that there is an electrical device 14 having a possibility of a life or abnormality, and is stored in the HDD 46, and the process proceeds to step 114. That is, when an electric device having a life or abnormality is found, the electric device 14 of the same type and installed at the same time may also have a life or an abnormality. Information is displayed on the display unit 40 and the information is stored in the HDD 46. Accordingly, the resident can know that an electric device 14 of the same type and that is installed at the same time as the electric device 14 that has been determined to have a life or abnormality may become a life or an abnormality. At the same time, maintenance can be performed.

  In step 114, it is determined by the control device 12 whether or not the system has been turned off. If the determination is negative, the process returns to step 100 and the above processing is repeated. When the determination is affirmative, a series of processing is performed. Exit.

  As described above, in the present embodiment, the power consumption of the electric device 14 is monitored, and based on the time point since the installation time, by determining the life or abnormality of the electric device based on the changing point of the power consumption. Thus, it is possible to more accurately determine the life or abnormality of the electrical device than when determining the life.

  In the above embodiment, the power sensor 28 is provided between the outlet 26 and the electric device 14. However, the present invention is not limited to this, and any electric device 14 and power consumption can be linked. For example, other configurations may be applied.
