Description

  The present invention relates to a watch notification device, a watch system, and a watch method for watching a target person using the consumption of resources in a device used by the watch target person.

  Conventionally, the difference between the data of the daily power usage of the user and the data of the daily power usage is obtained, and when the difference exceeds the threshold, it is determined that an abnormality has occurred and predetermined A technique for notifying a destination has been proposed (see, for example, Patent Document 1).

JP 2007-183890 A

  In the technique described in Patent Document 1, when the usage state of the user's power is different from the normal time, it is determined that an abnormality has occurred in the user and notified.

  However, just because the usage state of power is different from that in normal times, it does not necessarily mean that an abnormality has occurred in the user. Therefore, the technique described in Patent Literature 1 may increase the frequency of false alarms. . In addition, as a person who watches over the elderly, in applications such as notifying the family of living conditions of the elderly, even if the technique described in Patent Document 1 is used, notification is made only when it is determined to be abnormal. It is only done, and no sign of abnormality can be found.

  An object of the present invention is to provide a monitoring notification device, a monitoring system, and a monitoring method that can reduce the frequency of false alarms and can detect signs of abnormality of a subject.

The watching notification apparatus according to the present invention includes an acquisition unit, an evaluation unit, a generation unit, and a communication unit. The said acquisition part acquires the consumption of the resource by the apparatus used in the object space where the subject who watches over lives from a measuring device. The evaluation unit is configured to store the first consumption stored as a reference for the total value of the consumption for one day acquired by the acquisition unit and the consumption for the latest one day acquired by the acquisition unit. The difference from the second consumption, which is the total value, is evaluated. The generation unit generates notification information when there is no change in the second consumption amount with respect to the first consumption amount according to the evaluation of the evaluation unit. The communication unit transmits the notification information generated by the generation unit to a registered notification device through an electric communication line.

  The monitoring system according to the present invention is a monitoring system including a monitoring notification device and a server, and the server stores a list of contents of notification information for the past several days.

The monitoring method according to the present invention is a monitoring method used in a monitoring notification device including an acquisition unit, an evaluation unit, a generation unit, and a communication unit, and includes the following steps. The first step is a step in which the acquisition unit acquires the consumption amount of the resource by the device used in the target space where the watched target person lives from the measuring device. The second step is a first consumption amount stored as a reference for a total value of the acquired daily consumption and a total value of the acquired daily consumption for the second In this step, the evaluation unit evaluates the difference from the consumption. The third step is a step in which the generating unit generates notification information when there is no change in the second consumption amount with respect to the first consumption amount according to the evaluation. The fourth step is a step in which the communication unit transmits the generated notification information to a registered notification device through an electric communication line.

  According to the configuration of the present invention, the difference between the first consumption, which is the consumption during normal times, and the second consumption, which is the latest consumption, is evaluated, and notification information having different contents is generated according to the evaluation. Therefore, it is possible to reduce the frequency of false alarms as compared with the case where an abnormality is simply determined using a threshold value. In addition, since the notification information is generated according to the difference between the first consumption amount and the second consumption amount, by evaluating information such as the degree of difference and how the difference occurs, Signs may be found.

  As shown in FIG. 1, the watch notification device 10 described below includes an acquisition unit 11, an evaluation unit 12, a generation unit 13, and a communication unit 14. The acquisition unit 11 acquires the amount of resource consumption by the device 31 used in the target space where the watched person lives, from the measuring device 30. The evaluation unit 12 evaluates the difference between the first consumption that is the consumption acquired by the acquisition unit 11 during normal times and the second consumption that is the latest consumption acquired by the acquisition unit 11. The generation unit 13 generates notification information having different contents according to the evaluation of the evaluation unit 12. The communication unit 14 transmits the notification information generated by the generation unit 13 to the registered notification device 20 through the electric communication line 21.

  It is desirable that the notification information includes contact information that is a method for contacting the target person from the administrator of the notification device 20. Further, the communication unit 14 has a function of selecting a scheduled notification that notifies the notification device 20 of the notification information at a predetermined time and an immediate notification that notifies the notification device 20 of the notification information when the notification information is determined. It is desirable. In this case, it is desirable that the generation unit 13 has a function of selecting the content of the contact information depending on whether it is a scheduled notification or an immediate notification.

  It is desirable for the measuring device 30 to individually measure the consumption of a plurality of devices 31 of interest among the devices 31 used in the target space. In this case, it is desirable that the evaluation unit 12 sets the urgency level using a combination of consumption amounts for each device 31, and the generation unit 13 generates the content of the notification information according to the urgency level.

  The notification device 20 includes a display device 201. The notification information includes a first consumption amount and a second consumption amount, and the first consumption amount and the second consumption amount are arranged on the screen of the display device 201. It is desirable to display.

  In the configuration example described below, it is assumed that the target space is the house 40 and the target person is an elderly person. However, the target space is not limited to the house 40 as long as the target person lives for a long period of time, and may be a room in a facility. The target person is not limited to an elderly person, and may be a family who does not live together.

  The notification device 20 that receives notification information from the watch notification device 10 is selected from a smartphone, a tablet terminal, a mobile personal computer, and the like. These notification devices 20 include a display as the display device 201 and a touch panel or keyboard as the operation device 202. The telecommunication line 21 is assumed to be a VPN (Virtual Private Network) constructed on the Internet, but may be a mobile telephone network. When the telecommunication line 21 includes both the Internet and the mobile telephone network, a device such as a gateway or a server that relays between the Internet and the mobile telephone network is required for the telecommunication line 21.

  The watch notification device 10 may be an independent device, but in the following, it is assumed that the device is realized as a partial function of a HEMS controller (HEMS: Home Energy Management System). The HEMS controller is a controller that manages the operation of the device 31 used in the house 40.

  Hereinafter, the embodiment will be described in more detail. In the embodiment described below, as shown in FIG. 1, a case where the device 31 provided in the house 40 is configured to operate using electricity as a resource will be described as an example. That is, the device 31 is assumed to be an electrical device.

  However, the technical idea described below can be applied even when the device 31 that operates using gas or water as a resource is used. When the equipment 31 relating to cooking, hot water supply, heating, etc. operates using gas as a resource, it is possible to grasp the operating state of the equipment 31 by monitoring the gas flow rate measured by the gas meter that is the measuring device 30. is there. When the device 31 related to water supply, hot water supply, etc. operates using water as a resource, it is possible to grasp the operating state of the device 31 by monitoring the flow rate measured by the water meter that is the measuring device 30.

  In the present embodiment, since the device 31 is an electrical device that operates using power as a resource, the consumption amount of the resource (power) used by the device 31 is attached to or built in the distribution board 32 installed in the house 40. The measuring device 30 measures the amount of power. The measuring device 30 includes sensors (not shown) that respectively measure currents flowing through branch circuits branched into a plurality of systems in the distribution board 32. The measuring device 30 calculates the amount of power consumed for each branch circuit per unit time by using the current value measured by each sensor and the line voltage of the branch circuit. The sensor is selected from a clamp-type current transformer attached to the electric circuit of the branch circuit, a Rogowski coil incorporated in the distribution board 32, and the like.

  The unit time for the sensor to measure the electric energy is selected from 30 seconds, 1 minute, 2 minutes, 5 minutes, 10 minutes, and the like. Of course, these values are examples, and it is possible to measure the amount of power with a shorter time as a unit time. In addition, the measuring device 30 may employ a configuration that measures the amount of power for each device 31 instead of the amount of power for each branch circuit. If the length of the unit time is set to such an extent that it is not necessary to consider power fluctuations within the unit time, a value obtained by dividing the amount of power in the unit time by the unit time may be treated as an instantaneous value of power. . That is, the power consumption per unit time consumed by the device 31 reflects the instantaneous value of the power consumption of the device 31. Hereinafter, the power consumption per unit time consumed by the device 31 is referred to as “power consumption”. That is, in the following, the term “power consumption” means the amount of power (resource) consumed per unit time by the device 31.

  Generally, the distribution board 32 installed in the house 40 is a branch circuit of one circuit for the device 31 having a relatively large maximum power consumption, such as an air conditioner, a microwave oven, and an IH cooking heater (IH: Induction Heating). Assign. In addition, the distribution board 32 often assigns a branch circuit in units of rooms to a device 31 having a relatively small maximum power consumption, such as a device connected to an outlet or a lighting fixture. Even when the branch circuit is assigned to a single device 31, and even when the branch circuit is assigned to each room, the power consumption of each device 31 is determined from the power consumption of each branch circuit measured by the measuring device 30. Electric power can be obtained. Therefore, measuring the power consumption for each branch circuit by the measuring device 30 and measuring the power consumption for each device 31 may be regarded as equivalent in practice. Hereinafter, if it is not necessary to distinguish between a branch circuit and an individual device 31 as a unit for measuring power consumption, the unit will be described as a device 31.

  The watch notification device 10 includes an acquisition unit 11 that acquires power consumption measured by the measurement device 30. The acquisition unit 11 can acquire power consumption for all the devices 31 measured by the measurement device 30. However, the equipment 31 necessary for watching the target person differs depending on the house 40. Therefore, the watching notification device 10 includes a setting unit 15 so that the device 31 of interest can be selected. That is, the acquisition unit 11 acquires the power consumption of only the specific device 31 set by the setting unit 15.

  It is desirable that the setting unit 15 displays selectable device 31 options on the display device 201 described later. The options displayed on the display device 201 are selected when the user operates the operation device 202. The options displayed on the display device 201 are preferably specified using a room name or a device name so as to be easily understood by the user. The setting unit 15 may include the entire house 40 as an option.

  Since the processing load of the watch notification device 10 increases as the maximum number of selectable options increases, it is desirable that the maximum number of options that can be selected by the setting unit 15 is limited to about 4, for example. Assume that the branch circuit is assigned in units of rooms. In this case, for example, four types of “kitchen”, “living room”, “bedroom”, and “toilet / toilet” are selected by the setting unit 15.

  The power consumption for each device 31 acquired by the acquisition unit 11 is stored in the storage unit 17 together with the date and time counted by the clock unit 16. Here, it is assumed that the power consumption stored in the storage unit 17 is a unit of one day, but it is also possible to divide the day into a plurality of time periods. When dividing one day into a plurality of periods, the lengths of the individual periods may not be equal. In short, in the daily life of the subject's house 40, pay attention to the device 31 in which periodicity or habituality is found in the change in power consumption, and a period is set so that this periodicity or habituality can be extracted. That's fine. In addition, since changes in power consumption may differ between weekdays and holidays, it is desirable that the storage unit 17 be configured to distinguish the power consumption between weekdays and holidays.

  In the following configuration example, it is assumed that the power amount is acquired every hour for one day, and the storage unit 17 stores the power amount for at least one week. That is, the storage unit 17 stores 24 data (power consumption) per day, and stores 168 data per week.

  By the way, whether or not an abnormality has occurred in the watching target person is detected by comparison with the behavior of the target person in normal times. The watch notification device 10 extracts the transition of power consumption during normal times from the storage unit 17 with respect to the device 31 of interest, and determines the first consumption that serves as a reference for determining whether an abnormality has occurred in the subject. A reference unit 18 for generating and storing is provided.

  The first consumption amount is, for example, a value obtained by averaging the power consumption for each unit time having the same start time for the past several days stored in the storage unit 17 as the power consumption value for each unit time. . For example, the power consumption for 1 hour from 8:00 am to 9:00 am in the first consumption amount is assigned the average value of power consumption for 1 hour from 8:00 am to 9:00 am on 5 days from Monday to Friday. is there.

  For the first consumption, instead of using the average value for several days per unit time, it is possible to use the maximum value or the minimum value for several days per unit time. Further, the first consumption amount may not be the power consumption per unit time. For example, it is possible to divide a day into 3 to 4 sections, and use the total value of power consumption obtained for each section as the first consumption amount. It is also possible to use it as a consumption amount. Furthermore, it is possible to combine these values into the first consumption amount. The first consumption may be obtained for the specific device 31 set by the setting unit 15, but the first consumption may be obtained for all the devices 31.

  The evaluation unit 12 compares the second consumption, which is the latest power consumption acquired by the acquisition unit 11, with the first consumption stored in the reference unit 18, and compares the second consumption with the first consumption. Evaluate the difference from consumption. That is, the evaluation unit 12 evaluates whether the behavior of the target person is the same as that during normal time or different from normal time. Here, if the device 31 that easily reflects the life of the subject is selected by the setting unit 15, when the subject does not live normally (that is, when some abnormality occurs in the subject), Differences tend to appear with respect to power consumption during normal times.

  For example, in any of the devices 31 selected by the setting unit 15, if the power consumption in a certain time zone of the day is different from the normal power consumption by a predetermined reference value or more, the evaluation unit 12 Evaluates that the subject may have an abnormality. Alternatively, the evaluation unit 12 similarly applies to the case where the power consumption does not change even if the time has elapsed on the same day even though the power consumption has changed for each time zone with the passage of time during normal times. Assess that the subject may have an abnormality.

  The difference between the second consumption amount and the first consumption amount can be evaluated by a distance (Euclidean distance or Manhattan distance) between the second consumption amount and the first consumption amount. In this case, with respect to the first consumption amount and the second consumption amount, a difference for each unit time or for each section may be obtained and the sum of the differences may be used as the distance. The specific method of obtaining the distance differs depending on whether it is the Euclidean distance or the Manhattan distance, but regardless of which distance is used, the degree of the difference can be expressed quantitatively.

  The evaluation unit 12 may evaluate the difference between the second consumption amount and the first consumption amount in stages. As described above, if the degree of difference is expressed quantitatively, it is also possible to divide the difference into a plurality of stages by using a plurality of stages of threshold values.

  Here, when the difference between the second consumption amount and the first consumption amount is evaluated based only on the distance, the second consumption amount is shifted in the time axis direction with respect to the first consumption amount. May be perceived as a large difference. In this case, when the second consumption is shifted in the time axis direction with respect to the first consumption and the second consumption and the first consumption are overlapped, the second consumption and the first consumption are overlapped. It is expected that the difference from the consumption of 1 will decrease significantly. The occurrence of such an event is presumed to be due to the subject's getting up later than normal, but performing the same action as normal.

  Therefore, for example, the evaluation unit 12 sets the second value when the number of maximum values of the second consumption amount matches the number of maximum values of the first consumption amount (or when the error is ± 1). It is desirable to move the consumption amount in the time axis direction so that the degree of overlap with the first consumption amount is maximized. After the second consumption amount and the first consumption amount are relatively moved in the time axis direction in this way, the evaluation unit 12 determines the difference between the second consumption amount and the first consumption amount as a distance. You may evaluate by.

  The evaluation unit 12 desirably evaluates the difference in power consumption for the plurality of devices 31. That is, by selecting the device 31 in the setting unit 15, the acquisition unit 11 acquires the power consumption related to the plurality of devices 31. In the evaluation unit 12, the first consumption of the second amount of consumption is related to the plurality of devices 31. It is desirable to evaluate the difference to consumption.

  When a plurality of devices 31 are selected by the setting unit 15, the evaluation unit 12 may have an abnormality in the subject if the usage state of any of the plurality of devices 31 is different from the normal time. It can be determined that there is sex. Further, the evaluation unit 12 may determine the type of abnormality occurring in the subject person by combining the changes in power consumption extracted for the plurality of devices 31.

  Moreover, it is desirable for the evaluation unit 12 to set the urgency level by using the power consumption obtained for each of the devices 31 and combining the power consumptions for the plurality of devices 31 of interest. For example, if the urgency level is set higher as the number of devices 31 having a difference (distance) equal to or greater than the threshold value increases, the urgency level increases as more actions different from normal time occur.

  Furthermore, when the amount of electric power hardly changes over a plurality of time zones, and the difference between the maximum value or the minimum value during normal time for the corresponding device 31 is within a predetermined range, There is a possibility that the person is not operating the device 31. In such a case, the evaluation unit 12 evaluates that the subject's state is likely to be abnormal. In order to perform this evaluation, an upper limit value and a lower limit value of power consumption are set in the evaluation unit 12 for the device 31 of interest. The evaluation unit 12 may have an abnormality in the subject when the state where the power consumption is equal to or higher than the upper limit value or the state where the power consumption is equal to or lower than the lower limit value continues for a predetermined time. Assess that there is, increase the urgency.

  A result of the evaluation performed by the evaluation unit 12 on the subject is given to the generation unit 13, and the generation unit 13 generates notification information having different contents according to the evaluation of the evaluation unit 12. The notification information includes information on the content of a message to be notified to the notification device 20, contact information that is a communication method when the administrator of the notification device 20 contacts the subject, timing to notify the notification device 20, and evaluation. The information selected from the urgency evaluated by the unit 12 is included. That is, the generation unit 13 generates notification information having different contents according to the evaluation of the evaluation unit 12 for at least one of these pieces of information.

  The notification information generated by the generation unit 13 is transmitted to the notification device 20 registered in advance through the communication unit 14. The notification device 20 is managed, for example, by the family of the person being watched over. For example, when an elderly parent lives in the house 40, the notification device 20 is used for the child to watch the state of the parent. The communication unit 14 can operate as a scheduled notification that notifies the notification device 20 of the notification information at a predetermined time every day and an immediate notification that notifies the notification device 20 of the notification information when the notification information is determined. The time for performing the scheduled notification is set in the communication unit 14 in advance, as will be described later. Further, the timing for immediate notification follows the content of the notification information generated by the generation unit 13.

  Here, the example of a screen at the time of using a smart phone for the alerting | reporting apparatus 20 is shown in FIGS. Notification information is transmitted from the watch notification device 10 to the notification device 20 by a push method.

  FIG. 2 is a screen when the communication unit 14 transmits the notification information when the evaluation unit 12 evaluates that the subject person has no abnormality to the smartphone that is the notification device 20 by the regular notification. The illustrated example shows a state where the window A1 pops up on the screen of the notification device 20 with the reception of the notification information. In the window A1, a message “usually using power as usual” is displayed according to the notification information. That is, there is a high possibility that the subject has no abnormality.

  FIG. 3 shows an example of a screen when an application program (so-called “application”) for causing a smartphone to function as the notification device 20 is started. In this operation, similar to the operation example shown in FIG. 2, the notification information is received, and a message “usually using power as usual” is displayed. Here, a window C1 having a different shape from the window A1 shown in FIG. 2 is displayed. FIG. 3 also shows an arrow feather-shaped selection button B1 for selecting the subject's house. When the finger is slid in the direction of the selection button B1, the target house 40 is switched. Note that the house 40 being selected is displayed in an area adjacent to the selection button B1 (in the example shown, “XX house”).

  By the way, the administrator of the notification device 20 that has received the notification information through the notification device 20 does not need to contact the subject person as long as there is no problem with the subject as in the example of FIG. 2 or FIG. When an abnormality occurs in the subject, it is necessary to check the state of the subject. Since the abnormality of the subject is based on the transition of power consumption, the subject's life status is not necessarily abnormal, but it is desirable to contact the subject for confirmation. . Here, since the notification device 20 uses a smartphone, the notification device 20 includes a communication device 203 (see FIG. 1) such as a telephone and an e-mail, and the administrator uses these communication devices 203 to contact the target person. It is possible.

  Therefore, when the evaluation by the evaluation unit 12 is evaluated as not normal, for example, it is desirable to pop up a window C3 as shown in FIG. In the window C3, a message “There is no fluctuation in the power value for a long time” is displayed. This window C3 is displayed based on the notification information generated by the generation unit 13 when the state where the power consumption is equal to or higher than the upper limit value or lower than the lower limit value continues for a predetermined time. Further, the notification information includes contact information indicating a method for contacting the subject person from the administrator of the notification device 20. That is, as shown in FIG. 4, as a contact method, an operation button B2 for “telephone” and an operation button B3 for “email” are displayed in the window C3. By pressing B3, a screen corresponding to a telephone or e-mail is displayed. Here, if the phone number is registered in advance on the phone screen, it will be directed to the corresponding phone number, and if the email address is registered in advance on the email screen, the corresponding email address will be set. In this state, the e-mail program is started.

  As described above, the screen indicating the contact method is displayed on the display device 201 of the notification device 20, whereby the administrator of the notification device 20 is prompted to contact the target person. Therefore, when there is a possibility that an abnormality has occurred in the living state of the subject person, the administrator of the notification device 20 will be given an opportunity to contact the subject person, and the living state of the subject person will be confirmed without delay. Will do.

  An example of windows C1 to C3 popped up on the screen of the display device 201 in the notification device 20 in the regular notification is shown in FIGS. 5A to 5C, and an example of the window C4 popped up in the immediate notification is shown in FIG. Shown in (d). The example of FIG. 5A is the same as the example shown in FIG. 3, and the example of FIG. 5C is the same as the example shown in FIG.

  The example of FIG. 5B is an evaluation that the evaluation of the evaluation unit 12 is not normal, but shows a state of low urgency compared to the example of FIG. In other words, since the power consumption has changed, it is recognized that the subject is performing living activities, but the power consumption is less than normal, and the amount of behavior of the subject is less than normal. This indicates a possible situation. In such a case, a message such as “It seems that electricity is not used much today” is displayed in the window C2 of the notification device 20, and operation buttons B2 and B3 indicating a contact method are further displayed. .

  The window C2 in FIG. 5 (b) and the window C3 in FIG. 5 (c) not only differ in message content, but also differ in whether or not a mark indicating a difference in urgency is displayed. Since the state of FIG. 5C is considered to be more urgent than the state of FIG. 5B, a mark indicating an exclamation mark in a triangle is displayed in the window C3 of FIG. 5C. Has been. If this mark is given a color such as yellow, for example, the manager of the notification device 20 can be shown a high degree of urgency.

  FIG. 5D shows an example of an immediate notification window C4, which is substantially the same as the example shown in FIG. That is, the window C4 in FIG. 5D is displayed when the state where the power consumption is equal to or higher than the upper limit value or lower than the lower limit value continues. Messages and marks written in the window C4 are also displayed in the same manner. However, the e-mail operation button B3 is not displayed in the window C4, and only the telephone operation button B2 is displayed. The mark is given a color such as red, for example, and indicates a high degree of urgency. The reason why the operation method button B2 for the contact method is only a telephone in FIG. 5D is that there is no immediacy in electronic mail.

  Whether the window C3 in FIG. 5C or the window C4 in FIG. 5D is displayed depends on the degree of urgency evaluated by the evaluation unit 12. For example, as described above, when the power consumption is evaluated for a plurality of devices 31 and the degree of urgency is increased as the number of devices 31 that are not normal increases, the number of devices 31 shown in FIG. The window C3 and the window C4 in FIG. 5D are selected. Alternatively, not only the number of devices 31 that are not normal but also the window C4 of FIG. 5D may be displayed when it is evaluated that a specific device 31 is not normal.

  By the way, the time for performing the scheduled notification can be set as an operating device of the notification device 10 by watching the notification device 20. In other words, various settings in the watch notification device 10 can be interactively performed using the display device and the operation device attached to the watch notification device 10, but the functions of these display device and operation device are notified. A device 20 can be substituted.

  FIG. 6 is an example in which the time of the scheduled notification is designated from the notification device 20, and shows that the scheduled notification is performed from the watch notification device 10 to the notification device 20 at 7:00 and 21:00. The two times shown in the figure are associated with a switch B4 for selecting ON and OFF, respectively, and a scheduled notification is performed at the time when ON is selected by the switch B4. Note that it is possible to change and add the scheduled notification time. In addition, it is desirable that the setting unit 15 for selecting the device 31 in the watch notification device 10 can also be operated by the notification device 20 in the same way as the time of the scheduled notification.

  The screen shown in FIG. 7 is an example of a window E1 that displays a history regarding scheduled notification and immediate notification, and is displayed so that the contents of notification information for the past several days can be listed. In addition, if scrolling is performed on this screen, the content of the previous notification information can be confirmed.

  The screen shown in FIG. 8 shows the transition of power consumption in the entire house 40 for the past several days. By enabling such a display, it is possible to easily read whether or not a change in power consumption has occurred in a few days. That is, if the evaluation by the evaluation unit 12 is normal until the previous day, the power consumption transition D2 during normal times is indicated until the previous day. The administrator of the notification device 20 can easily identify what kind of abnormality has occurred in the power consumption by comparing the transition D2 with the power consumption transition D1 of the day. The information shown in FIGS. 7 and 8 can be held by the watch notification device 10 or the notification device 20, but may be held in a separate server or cloud server.

  The example shown in FIG. 9 is a screen showing a list of changes in power consumption in one day for each device 31 (branch circuit) selected by the setting unit 15. By displaying such a screen, the target person It becomes possible to grasp the behavior of

  As described above, the watch notification device 10 is preferably provided in the HEMS controller that manages the operation of the device 31 used in the house 40. Although not intended to limit the configuration, the HEMS controller assumed here monitors the operation of the device 31 and controls the operation of the device 31 by performing wireless or wired communication with the device 31. It is possible to do. The HEMS controller has a function of visualizing the power consumption by monitoring the power consumption of each branch circuit acquired from the measuring device 30 and suppressing the power consumption by the device 31. The HEMS controller may have a communication function with the watt hour meter.

  The monitoring notification apparatus 10 described above includes a device including a processor that operates according to a program and an interface device as main hardware elements. As a device including a processor, a microprocessor having a processor and a memory integrally, a processor having a memory as another device, and the like are used.
