(Data receiving device).

In the electric energy metering system according to the above-described embodiment, the occupancy and absence of each room are determined from the detailed electric energy data, and the state of the occupant is estimated from these determination results. The transition patterns corresponding to each state of the resident at home, going out, and sleeping for 24 hours of the total power consumption (before power distribution) are stored in advance, and these transitions and the power actually stored are stored. By comparing the data with the data, the state of the occupant can be estimated from the similarity.

A PC, a home server, or the like may be used in place of the watt hour meter of the power management system according to the above-described embodiment, and one or more sensors have detected any abnormality. Instead of a security company,
Notification may be made to a welfare service company or the like.

In addition, in the watt hour meter of the watt hour metering system of the above embodiment, the integrated value of the amount of power at every predetermined time interval is stored. The quantities can be stored as is and used to estimate whether the resident is out or not.

In the electric energy metering system according to the above-described embodiment, the notification data is transmitted to the electric energy management device, and the operator issues an alert to the security company in response to the display based on the notification data. Alternatively, the notification can be made directly from the watt hour meter to the notification receiving system.

In the electric energy metering system according to the above-described embodiment, it is assumed that a human sensor is used to detect an illegal intruder. However, the presence of a person is detected by an open / close sensor attached to the door. It may be detected and other sensors such as fire sensors may be used.

Further, as in the electric energy metering system according to the above-described embodiment, the determination as to whether or not the user is out of the office is not made based on the information on the electric energy used or the detection state of the sensor. It can be performed using the location information providing service. In the notification system using this location information providing service, when a human sensor or the like responds, the system determines whether or not the user is out based on the location information of the PHS terminal carried by the resident, and Only at certain times, the watt hour meter causes the power management device to transmit the alarm data.

In the electric energy metering system of the above embodiment, a human sensor or the like is directly connected to the electric energy meter. A watt hour meter may be connected to a controller to which a feeling sensor or the like is connected, and the detection state of the sensor or the like may be transmitted via the controller.
