LAN etc.) are used.

Each branch circuit 92 is connected to one or more electrical devices 6 such as an air conditioner, a lighting fixture or a television, and the branch circuit 92 supplies operating power to these electrical devices 6. Further, the main line circuit 91 and the branch circuit 92 may be supplied with power generated by a distributed power source such as a solar power generation device, a fuel cell, or a wind power generation device, and discharge power of a storage battery. The branch circuit 92 is configured by a wiring device such as a distribution line or an outlet.

The controller 3 is, for example, a HEMS (Home Energy Management System) controller, and includes a power data generation unit 31 and a power data transmission unit 32. The controller 3 may further include a device monitoring unit 33.

The power data generation unit 31 receives branch power measurement data from the power measurement unit 22, and generates power consumption data (also referred to as power data) for each electrical device 6 from the branch power measurement data. Specifically, the power data generation unit 31 extracts fluctuations in power consumption for each electrical device 6 by analyzing the waveform of the branch power measurement data in the time domain and frequency analysis in the frequency domain. Power data can be generated. In addition, the power data generation unit 31 stores in advance a variation type of power consumption at the time of operation and stop for each type of electrical device 6 connected to each branch circuit 92. Yes. Therefore, the power data generation unit 31 can determine the type and installation location of the electrical device 6 corresponding to the extracted fluctuations in power consumption, and can add information on the type and installation location of the electrical device 6 to the power data. .

In addition, the electric device 6 has a function of performing communication (specifically, wired communication or wireless communication) with the controller 3, and notifies the controller 3 of each state of operation (ON) or stop (OFF) of itself. You may send it. In this case, the power data generation unit 31 extracts fluctuations in power consumption for each electrical device 6 based on the operation and stop status of the electrical device 6 and the analysis result of the branch power measurement data, The power data for each device 6 can be generated.

In addition to the function of communicating with the controller 3, the electrical device 6 may further include a function of measuring its own power consumption. In this case, the power data generation unit 31 can generate power data for each electrical device 6 based on the measurement result of the power consumption of the electrical device 6 received from the electrical device 6.

The power data is data representing an integrated value per unit time of power consumption for each electrical device 6 (for example, a second unit of 1 second to 60 seconds, or a minute unit of 1 minute to 60 minutes).

The power data transmission unit 32 transmits power data to the management server 4. The power data generation unit 31 has a real-time clock function, and adds power data measurement time information to the power data. The power data transmission unit 32 is communicably connected via a router 500 to a wide area network 8 (for example, a public network) such as the Internet. The power data transmission unit 32 can communicate with the management server 4 on the wide area network 8 and transmits power data to the management server 4. Customer information assigned to the building 100 or measurement time information is added to the power data transmitted by the power data transmission unit 32. The customer information includes ID information of the building 100.

The device monitoring unit 33 monitors and controls the operation of the electric device 6 via the router 500, and can construct a HEMS by using the power data together. In HEMS, the device monitoring unit 33 has a function of visualizing power consumption (also referred to as “visualization”) by presenting power data to an appropriate presentation device. In the HEMS, the device monitoring unit 33 has a function of controlling the electric device 6 for the purpose of power saving based on the power data. That is, the controller 3 also functions as a HEMS controller.

The management server 4 receives the power data from the power data transmission unit 32 through the wide area network 8 and stores the power data corresponding to the customer information of the building 100. That is, the management server 4 stores a history of power data for each electrical device 6 in the building 100. In FIG. 1, only one building 100 is illustrated, but the history of power data in each of the plurality of buildings is associated with the customer information of each of the plurality of buildings, with a plurality of buildings being contracted. It is stored in the management server 4.

Further, the power data transmission unit 32 may transmit the power data to the management server 4 only when the power data has changed by a predetermined amount or more in order to reduce communication traffic. That is, the management server 4 stores a continuous history of power data by interpolating using the power data before and after the period during a period when the power data is not received.

The bedtime monitoring device 1 is configured to be able to perform network communication using the wide area network 8. The bedtime monitoring device 1 includes an analysis server 11 and an application server 12, and the analysis server 11 and the application server 12 can communicate with each other through the wide area network 8.

The analysis server 11 includes a communication unit 111, a power information acquisition unit 112, a reference storage unit 113, and a bedtime determination unit 114. The analysis server 11 may further include a history storage unit 115, a reference data generation unit 116, and an estimation unit 117.

The communication unit 111 has a function of performing network communication through the wide area network 8.

The power information acquisition unit 112 acquires power data from the management server 4 via the communication unit 111 and stores the history of the acquired power data in the history storage unit 115. Information on the type and installation location of the electric device 6 is added to the power data, and information on the type and installation location of the electric device 6 is associated with the power data stored in the history storage unit 115. ing.

The reference storage unit 113 stores reference data corresponding to customer information. The reference data is data used when the sleep determination unit 114 determines the presence or absence of a person's sleep behavior. The electric power data is associated with the type and installation location of the electric device 6, and the reference data is the state of the electric device 6 based on the electric power data when a person goes to sleep in a building (for example, the building 100). This is a time-series variation according to the type and installation location of the electric device 6.

The sleeping action is a series of actions that are performed before a person enters the bedding. Generally, the sleeping action varies depending on the attributes of the person who performs the sleeping action (for example, family composition, personal attributes, floor plan of the building 100, etc.). That is, the change in the state of the electric device 6 that occurs when a person goes to sleep is almost determined for each type and installation location of the electric device 6 depending on the attribute of the person who goes to sleep. The reference data is a reference form of the state change of the electric device 6 determined by the attribute of the person who performs this sleeping action.

The bedtime determining unit 114 compares the state of the electrical device 6 based on the power data acquired by the power information acquiring unit 112 with the reference data of the reference storage unit 113 to determine whether there is a sleeping behavior of a householder. Can do. The communication unit 111 transmits the determination result of the bedtime determination unit 114. In the reference storage unit 113, reference data for each of a plurality of buildings is stored in association with customer information of each of the plurality of buildings.

The application server 12 includes a communication unit 121, a request acquisition unit 122, and a notification data generation unit 123.

The communication unit 121 has a function of performing network communication through the wide area network 8. The request acquisition unit 122 can acquire a request for notification of sleeping behavior determination from the terminal device 5 via the communication unit 121. The notification data generation unit 123 can acquire the determination result of the bedtime determination unit 114 from the analysis server 11 via the communication unit 121. Furthermore, the notification data generation unit 123 generates notification data that notifies the determination result of the bedtime determination unit 114. The communication unit 121 transmits the notification data to the terminal device 5.

The terminal device 5 is a portable terminal that can be carried by the user, such as a mobile phone, a smartphone, and a tablet terminal, and can display notification data received from the application server 12 through the wide area network 8 on the screen.

Hereinafter, the operation of the sleep monitoring system of the present embodiment will be described in detail using the flowchart of FIG.

A user (e.g., a father) who returns to the building 100 from his / her office or the like operates the terminal device 5 and knows whether the housekeeper in the building 100 is sleeping or not, and adds the ID information of the building 100 The request is transmitted to the application server 12. This notification request is a command for requesting whether or not there is a sleeping action in the building 100. FIG. 3 is an example of a request transmission screen displayed on the screen of the terminal device 5, and a notification request is transmitted from the terminal device 5 when the confirmation button B <b> 1 is pressed. Note that FIG. 3 shows a request transmission screen 201 for requesting the presence / absence determination of a child's sleeping behavior, and the user can transmit a notification request from the terminal device 5 by pressing the confirmation button B1. .

When the request acquisition unit 122 of the application server 12 acquires a notification request through the communication unit 121 (S1), the request acquisition unit 122 transfers the notification request to the analysis server 11 through the communication unit 121 (S2).

In the analysis server 11, when the communication unit 111 receives the notification request, the power information acquisition unit 112 causes the communication unit 111 to transmit a data request for the power data in the building 100 to the management server 4 (S3). Note that ID information of the building 100 is added to the data request.

When the management server 4 receives the data request, the management server 4 transmits a history of power data in the building 100 from a predetermined time before the reception time of the data request, and further receives a history of power data of the building 100 received after the reception time of the data request. Also starts processing to sequentially transmit to the analysis server 11. That is, the power information acquisition unit 112 of the analysis server 11 acquires each power data of the electrical equipment 6 in the building 100 from the management server 4 via the communication unit 111 (S4).

Then, the sleep determination unit 114 compares the time-series change state of the state of the electrical device 6 based on the power data with the reference data in the reference storage unit 113, and determines whether or not there is a sleeping behavior of a householder (S5). ). Here, each piece of information on the type and installation location of the electrical device 6 is added to the power data, and the sleep determination unit 114 responds to the power data based on the information added to the received power data. The type and installation location of the electric device 6 can be recognized. Note that the types of electrical equipment 6 include lighting fixtures, air conditioners, etc., and the installation locations of the electrical equipment 6 include entrances, living rooms, kitchens, toilets, baths, washrooms, children's rooms, parents' bedrooms, etc. .

An example of the floor plan of the building 100 is shown in FIG. The building 100 includes rooms 100a, a living room 100b, a kitchen 100c, a toilet 100d, a bath 100e, a bathroom 100f, a children's room 100g, and a parents' bedroom 100h, and a hallway 100i connects the rooms.

And the lighting fixture 61a is installed in the entrance 100a, the lighting fixture 61b is installed in the living room 100b, and the lighting fixture 61c is installed in the kitchen 100c. Furthermore, a lighting fixture 61d is installed in the toilet 100d, a lighting fixture 61e is installed in the bath 100e, and a lighting fixture 61f is installed in the bathroom 100f. Furthermore, a lighting fixture 61g is installed in the child room 100g, and a lighting fixture 61h is installed in the bedroom 100h of the parents.

Also, an air conditioner 62b is installed in the living room 100b, an air conditioner 62g is installed in the child room 100g, and an air conditioner 62h is installed in the parents' bedroom 100h.

Here, when the lighting fixtures 61a to 61h are not distinguished, they are referred to as lighting fixtures 61. Further, when the

air conditioners

62b, 62g, and 62h are not distinguished, they are referred to as air conditioners 62. Furthermore, when it does not distinguish the lighting fixture 61 and the air conditioner 62, it calls the electric equipment 6. In addition, the electric equipment 6 is not limited to the lighting fixture 61 and the air conditioner 62, Other electric equipments (for example, a television, a personal computer, etc.) are also included.

As a first example of sleeping behavior, there is behavior in a child room 100g. For example, the child enters the children's room 100g, turns off the lighting fixture 61g, and turns off the lighting fixture 61g after preparation for sleeping is completed. The reference data in this case indicates the state change state of the lighting fixture 61g by the power consumption, and the power consumption of the lighting fixture 61g is from the state below the threshold (light-off state) to the state above the threshold (lighting state). Then, the state becomes less than the threshold value.

As a second example of sleeping behavior, there are behaviors in the living room 100b, the washroom 100f, and the child room 100g. For example, the child turns off the lighting fixture 61b in the living room 100b, turns on the lighting fixture 61f in the bathroom 100f, brushes the teeth, and turns off the lighting fixture 61f. Then, the child enters the child room 100g, turns off the lighting fixture 61g, and turns off the lighting fixture 61g after preparation for sleeping is completed. The reference data in this case indicates the state of change of the

lighting fixtures

61b, 61f and 61g by the power consumption. Specifically, after the power consumption of the luminaire 61b changes from a state equal to or higher than the threshold (lighted state) to a state less than the threshold (light-off state), the power consumption of the luminaire 61f is lower than the threshold (light-off state). ) To a state equal to or higher than the threshold (lighting state), and then to a state below the threshold. Next, the power consumption of the luminaire 61g changes from a state less than the threshold value (light-off state) to a state equal to or higher than the threshold value (light-on state), and then goes to a state below the threshold value.

As a third example of sleeping behavior, there is behavior in the living room 100b and the bedroom 100h. For example, the mother turns off the lighting fixture 61b in the living room 100b, enters the bedroom 100h, turns on the lighting fixture 61h, and turns off the lighting fixture 61h after preparation for sleeping is completed. The reference data in this case shows the change form of each state of the

lighting fixtures

61b and 61h by power consumption. Specifically, after the power consumption of the luminaire 61b is changed from the state above the threshold (lighted state) to the state below the threshold (light off state), the power consumption of the luminaire 61h is below the threshold (light off state). ) To a state equal to or higher than the threshold (lighting state), and then to a state below the threshold.

Further, the reference data of the third example described above may be in the following form. The power consumption of the lighting fixture 61b is less than the threshold value (light-off state), and the power consumption of the lighting fixture 61h changes from the lower threshold value (light-off state) to the threshold value (lighting state), and then less than the threshold value. It becomes the state of.

As a fourth example of sleeping behavior, there is another behavior in the living room 100b and the bedroom 100h. For example, the mother goes to bed while the air conditioner 62b of the living room 100b is in an operating state for the father to return home. Specifically, the mother enters the bedroom 100h with the air conditioner 62b in the living room 100b in the operating state, turns on the lighting fixture 61h in the off state, and turns off the lighting fixture 61h after preparation for sleeping is completed. The reference data in this case shows the change form of each state of the lighting fixture 61h and the air conditioner 62b by power consumption. Specifically, the power consumption of the air conditioner 62b is greater than or equal to a threshold (operating state), and the power consumption of the lighting fixture 61h is changed from a state less than the threshold (light-off state) to a state greater than or equal to the threshold (lighted state). Then, the state becomes less than the threshold value.

As a fifth example of the sleeping behavior, there is a case where the lighting device 61b of the living room 100b is turned off while the air conditioner 62b of the living room 100b is in an operating state for a father who goes home, and then goes to sleep. Specifically, the mother maintains the air conditioner 62b in the living room 100b in an operating state and turns off the lighting fixture 61b that is turned on in the living room 100b. Then, the mother enters the bedroom 100h, turns on the lighting fixture 61h in the off state, and turns off the lighting fixture 61h after preparation for sleeping is completed. In this case, the reference data indicates the state changes of the

lighting fixtures

61b and 61h and the air conditioner 62b by the power consumption. Specifically, the power consumption of the air conditioner 62b is equal to or greater than a threshold value (operating state). And after the power consumption of the lighting fixture 61b changes from the state (lighting state) more than a threshold value to the state (light-off state) less than a threshold value, the power consumption of the lighting fixture 61h is a threshold value from the state (light-off state) less than a threshold value. It will be in the above state (lighting state), and will be in a state below a threshold value after that.

The reference data is not limited to the first to fifth examples described above, and may be data indicating a time-series change form of power data generated when a person goes to sleep. That is, there are no particular limitations on the type of electrical equipment 6 that constitutes the reference data, the installation location, and the state of change (for example, power consumption).

The sleeping determination unit 114 can determine whether or not there is a sleeping behavior of a householder by pattern recognition processing that compares the change form of the power data with the reference data of the reference storage unit 113. If the similarity between the time-series change state of the state of the electrical device 6 and the reference data is equal to or greater than the threshold, the bedtime determination unit 114 determines that there is a family member's bedtime behavior. Furthermore, although it is considered that the time required for a series of changes in the state of the electrical device 6 during the sleeping action may vary, the sleeping determination unit 114 performs a normalization process or the like on the power data. The determination accuracy can be improved.

In addition, a plurality of pieces of reference data are stored in the reference storage unit 113, and the bedtime determination unit 114 has reference data in which the degree of similarity with the time-series change state of the state of the electrical device 6 is greater than or equal to a threshold value. It may be determined that there was a sleeping behavior of a householder.

Furthermore, when the bedtime determination unit 114 determines that there was a sleeping behavior of a family member, the detection time of the bedtime behavior is within a predetermined time zone (for example, from 9:00 pm at night to 6:00 am on the next day). This determination result may be valid only in the case. That is, depending on the behavior of a householder other than at night, the state change of the electric device 6 may be similar to the reference data even if it is not a sleeping behavior. Therefore, when the sleep determination unit 114 determines that there is a sleeping behavior of a householder, if the detection time of the sleeping behavior is not within a predetermined time zone, the determination result is invalidated, thereby causing an error in sleeping behavior. Judgment is suppressed.

Then, when the sleep determination unit 114 determines that there is a sleeping behavior of a householder in the building 100, it transmits a determination notification to the application server 12 via the communication unit 111 (S6). This determination notification includes information on a family member who has gone to bed in the building 100 and power fluctuation information indicating the transition of power data before and after the bedtime behavior.

In the application server 12, when the communication unit 121 receives the determination notification, the notification data generation unit 123 generates notification data for notifying the determination result of the bedtime determination unit 114 based on the determination notification (S7). When the sleeping determination unit 114 detects the sleeping behavior of the child, notification data is generated that displays the detection time of the sleeping behavior of the child, the duration of the sleeping state, and the transition of the power data before and after the sleeping behavior (see FIG. 5). ).

Then, the communication unit 121 transmits the notification data generated by the notification data generation unit 123 to the terminal device 5 (S8). The terminal device 5 that has received the notification data displays a notification screen 202 that notifies the notification data as shown in FIG. In the notification screen 202, the detection time of the sleeping behavior and the duration of the sleeping state are represented by a graph 202a, and the transition of power data before and after the sleeping behavior is represented by a graph 202b.

The user who sees the notification screen 202 recognizes that the child has gone to bed, and can take a response to return home quietly so as not to disturb the child's bedtime when returning to the building 100.

In addition, when it is determined that there is no sleeping behavior of the householder, the sleeping determination unit 114 may transmit a determination notification that the householder is not sleeping through the communication unit 111 to the application server 12. In this case, the notification data generation unit 123 generates notification data that notifies the determination result that the family member is not sleeping, and the communication unit 121 transmits the notification data to the terminal device 5. Then, the terminal device 5 that has received the notification data displays a notification screen including a message that the family member is not sleeping. The determination notification may include power fluctuation information indicating the transition of power data up to the current time. In this case, the notification screen displays a graph of the transition of power data up to the current time.

In the analysis server 11, the power information acquisition unit 112 may cause the communication unit 111 to transmit a data request for the power data in the building 100 to the management server 4 at a predetermined time. And the power information acquisition part 112 of the analysis server 11 acquires each power data of the electric equipment 6 in the building 100 from the management server 4 via the communication part 111. Then, the sleep determination unit 114 compares the time-series change state of the state of the electrical device 6 based on the power data with the reference data in the reference storage unit 113, and determines whether there is a sleeping behavior of a householder.

That is, the bedtime determination unit 114 compares the time-series change state of the state of the electrical device 6 with the reference data in the reference storage unit 113 at a predetermined time, and determines whether or not there is a sleeping behavior of a householder. .

Alternatively, the notification data generation unit 123 may generate the following notification data.

First, when it is determined that there is a sleeping behavior, the notification data generation unit 123 determines whether or not the current time is within a predetermined time (for example, within 30 minutes) from the occurrence time of the sleeping behavior. And the notification data production | generation part 123 will produce | generate the 1st notification data which notifies that there was a sleeping action, if the present time is less than predetermined time from the generation | occurrence | production time of a sleeping action. Then, the communication unit 121 transmits the first notification data generated by the notification data generation unit 123 to the terminal device 5. As illustrated in FIG. 6A, the terminal device 5 that has received the first notification data displays a notification screen 211 that notifies the first notification data, and notifies the user that the child has taken a sleeping action. In the notification screen 211, the transition of the power data before and after the sleeping action is represented by a graph 211a.

Further, the notification data generation unit 123 generates second notification data for notifying that the user is sleeping if the current time exceeds a predetermined time from the occurrence time of the sleeping action. Then, the communication unit 121 transmits the second notification data generated by the notification data generation unit 123 to the terminal device 5. As illustrated in FIG. 6B, the terminal device 5 that has received the second notification data displays a notification screen 212 that notifies the second notification data, and notifies the user that the child is sleeping.

That is, when the notification data generation unit 123 generates notification data within a predetermined time from the occurrence time of the bedtime action, the notification data generation unit 123 notifies the user that there was a bedtime action. On the other hand, the notification data generation unit 123 notifies the user that the user is sleeping when generating notification data after a predetermined time has elapsed from the occurrence time of the sleeping action.

Therefore, the user can grasp the state of the child who has gone to sleep (the state that is not long after taking the sleep behavior or the state that is assumed to be sleeping).
