  FIG. 6A shows an outline of setting of the target power consumption Pm executed by the monitoring control panel 42. For example, the consumption target power Pm is displayed by operating a menu switch 52C provided in the U / I 50 to display a UI for setting the consumption target power Pm on the display 52A.

  In this flowchart, the time zone is designated in the first step 100, and in the next step 102, the consumption target power Pm in the designated time zone is input. Also, in step 104, it is confirmed whether or not the setting is completed, and by setting the consumption target power Pm for all the time zones, an affirmative determination is made in step 104, the process proceeds to step 106, and is set. The consumption target power Pm is stored in the HDD 44D, and the process ends.

  When setting the target consumption power Pm for the next time zone, a negative determination is made in step 104 and the process proceeds to step 100, where the target consumption power Pm for the next time zone is set. In addition, when changing the consumption target electric power Pm about a part of time slot | zone, the applicable time slot | zone is selected at step 100, and the consumption target electric power Pm of the time slot | zone selected at step 102 is input.

  Here, the time zone can be set in units of one hour, whereby the consumption target power Pm is set every hour for 24 hours per day. In addition, the time zone is preferably divided into about one hour, but is not limited to this, and may be in units of two hours, taking into account the daily life cycle of the resident and the charge of the system power supply 12. Can be classified. In this case, for example, from 11 pm to 6 am (midnight and early morning), from 6 am to 9 am (morning), from 9 am to 4 pm (daytime), from 4 pm to 6 pm (evening) Obi), 6:00 pm to 11 pm (nighttime), etc.

  For example, when the contract power is set for the system power supply 12, the target consumption power Pm is set by using the contract power as an upper limit, considering the power of the electrical equipment used in the house 10, the usage status, and the suppression of power consumption. The user can arbitrarily set it. At this time, for example, if the contract power is 40 A with single-phase three-wire 100V / 200V, 8 kw is the upper limit, and if the contract power is 30 A, 6 kw is the upper limit.

  The target consumption power Pm is determined in consideration of the contract power, for example, the target power consumption Pm is increased in the time zone where the power is most used, for example, from evening to night. Lower Pm. As the consumption target power Pm, a plurality of patterns are stored in advance according to the contract power, the floor area of the house, the number of residents, and the like, so that any one of the patterns stored by the residents is temporarily selected. Anyway.

  FIG. 7A shows an example of a pattern of the consumption target power Pm based on the hourly power consumption of the house 10. In this consumption target power Pm pattern, the values for the respective time zones are such that the storage battery 22 and the storage battery of the vehicle 24 are charged in the late night charge time zone from 11:00 pm (23:00) to 6:00 am. Is set.

  Moreover, when the solar power generation device 16 is provided, as shown in FIG. 7B, the generated power of the solar power generation device 16 can be obtained during the daytime (daytime). From here, in the pattern of the consumption target power Pm shown in FIG. 7A, the consumption target power Pm is constant in a time zone (for example, from 4 pm to 8 am) when the power generation power of the solar power generation device 16 is not obtained. In the daytime period (9 am to 3 pm) in which the power generated by the solar power generation device 16 is obtained, the consumption target power Pm is set low so that the power generated by the solar power generation device 16 is consumed. In addition, the power can be set to be sold when surplus power is generated.

  On the other hand, in the monitoring control panel 42, device information including at least priority for use and information for identifying the electrical device (hereinafter, referred to as device ID as an example) is input by the resident for each electrical device used in the house 10. Thus, registration of each electric appliance is performed. As the device ID included in the device information, a unique code is used for each electrical device that enables the monitoring control panel 42 to identify the electrical device. Any known configuration can be applied to such a code.

  The monitoring control panel 42 communicates with each electrical device using the device ID to grasp whether or not the corresponding electrical device is operating, the power consumption during the operation, and when stopping the electrical device, Used to identify electrical equipment to be stopped.

  FIG. 6B shows an example of the priority order input as device information. In this priority order, the lighting fixture 26 and the refrigerator 28 are set to level 1 where the operation is given the highest priority, and the lighting of the house is turned off at night or the refrigerator 28 is prevented from functioning due to a power failure. ing.

  Moreover, the storage battery 22 (charger / discharger 22A of the storage battery 22), the vehicle 24 (charger / discharger 24A of the vehicle 24), etc. are set to the level 2 made into the next priority. Moreover, the air conditioner 36 etc. are set to the level 4 with the lowest priority. Furthermore, in level 3, it is possible to set AV appliances such as televisions and stereos, home appliances around the kitchen such as microwave ovens, toasters, and electric rice cookers.

  In addition, for example, when there are a plurality of electric devices of the same type, such as air conditioners 36 installed in a plurality of rooms, the priority order may be set for each electric device. A priority order may be set.

  The priority order of the electrical equipment may be stored as the default priority order for each electrical equipment, and this default priority order may be used. Also, if necessary, the resident assigns the default priority order of the electrical equipment. You may change for every kind or every electric equipment. Further, here, the priority is set to four levels from level 1 to level 4, but it may be configured such that the priority can be set finely by setting at least two levels or more and four levels or more.

  The device information can include an installation location in the house 10. When the installation location is included in the device information, the monitoring control panel 42 displays a UI for inputting the installation location in the house 10 for each electrical device on the display 52A. The installation location may be input, for example, by registering a floor plan in the house 10, displaying the floor plan (floor plan) on the display 52A, and inputting the position of each electrical device.

  FIG. 8 shows an example at this time. In FIG. 8, only a part of the electric equipment is illustrated. As shown in the floor plan 66, in the house 10, a lighting device 26, an air conditioner 30, and home appliances (not shown) such as a television are arranged in a living room 68, and a kitchen 70 is illuminated. An appliance 26, a refrigerator 28, and the like are arranged. At this time, for example, when the air conditioner 30 is also provided in the Japanese room 72, the air conditioner 30 (30A) in the living room 68 and the air conditioner 30 (30B) in the Japanese room 72 are input so as to be identified. In addition, although it demonstrates so that the position of an electric equipment may be specified on the floor plan 66 here, it is not restricted to this, As long as a resident can specify the installation position of an electric equipment, it is a living room name etc. Arbitrary structures, such as using the information which specifies are applicable.

  When the priority order for each electrical device is set based on the input device information for each electrical device, the monitoring control panel 42 of the consumption monitoring system 40 registers the electrical device by storing it in the HDD 44D together with the priority order. When the installation position of the electrical device is included in the device information, the electrical device is registered including the installation location. The consumption monitoring system 40 (monitoring control panel 42) monitors the power consumption with respect to the consumption target power Pm and notifies the monitoring result based on the registered contents of each electric appliance.

  Hereinafter, the power consumption monitoring process executed by the monitoring control panel 42 of the consumption monitoring system 40 will be described.

[First Embodiment]

  FIG. 9 shows an overview of the monitoring process according to the first embodiment. In this flowchart, it is executed at a preset time interval (for example, about 1 to 10 minutes), and in the first step 110, the current value detected by the current sensor 56 is read to reduce the power consumption of the lighting fixture 32. To detect. At the same time, the monitoring control panel 42 communicates with each electric device to identify the electric device in operation and detect the power consumption value (hereinafter referred to as power consumption) of the identified electric device. In addition, the detection of the power consumption of each electric appliance excluding each certification instrument 26 may be calculated by detecting the current consumption using a current sensor, or may be detected using a wattmeter. .

  In the next step 112, the total power consumption Pc at that time in the house 10 is calculated from the detected power consumption. In step 114, the calculated total power consumption Pc is compared with the target consumption power Pm in that time period, and the total power consumption is calculated. It is confirmed whether or not the power Pc exceeds the consumption target power Pm.

Here, if the total power consumption Pc is equal to or less than the target consumption power Pm (Pc ≦ Pm), a negative determination is made in step 114, the process proceeds to step 116, and the target consumption power Pm and the total power consumption Pc are displayed on the display 52A. To do. In the next step 118, the total power consumption Pm is stored in the HDD 44D as a history.
In FIG. 9, the total power consumption Pc is detected at a preset time interval, and it is confirmed whether or not the detected total power consumption Pc exceeds the consumption target power Pm. For example, it is confirmed whether or not the total power consumption Pc exceeds the target consumption power Pm by continuously detecting the total power consumption Pc (detecting an instantaneous value) and comparing it with the target power consumption Pm. Any configuration for comparing the total power consumption Pc and the target consumption power Pm can be applied.

  FIG. 10A shows a display screen 74 as an example of display on the display 52A. On this display screen 74, the target power consumption Pc set for the time zone is displayed, and the total power consumption value Pm calculated at that time is displayed. The resident can confirm how much power is consumed at that time by looking at the display on the display 52A and recognize the difference between the total power consumption Pc and the target power consumption Pm set by the resident. Can do.

  On the other hand, when the total power consumption Pc exceeds the target consumption power Pm (Pc> Pm), in the flowchart shown in FIG. In this step 120, the priority order registered for each of the operating electrical devices is read, and the electrical device with the lowest priority is selected. At this time, if there are a plurality of electrical devices with the corresponding priority, each electrical device is selected. In step 122, it is confirmed whether or not an electric device with a low priority is operating.

  Here, if the level 3 or level 4 electrical device whose priority is lower than level 2 or level 2 is operating, an affirmative determination is made at step 122 and the routine proceeds to step 124. In this step 124, the display 52A is displayed so as to notify the resident that the excessive power consumption has occurred with the total power consumption Pc exceeding the target power consumption Pm. At the same time, by displaying the selected electric device on the display 52A, the electric device to be stopped in order to reduce power consumption is presented.

  FIG. 10B shows a display screen 76 as an example at this time. On this display screen 76, a message 78 indicating that the total power consumption Pc has exceeded the target power consumption Pm is displayed. The display screen 76 displays a message 80 that suggests that the selected device be stopped. At this time, since the air conditioner 30 is operating and the priority order of the air conditioner 30 is the lowest among the operating electric devices, a message 80 recommending that the air conditioner 30 be stopped is displayed on the display screen 76. The

  On the display screen 76, a confirmation button 80A is displayed for the message 80. Thereby, the resident who has seen the display on the display 52A can operate (touch) the confirmation button 80A to instruct to stop the presented electrical device (acknowledge the stop).

  Here, two messages 78 and 80 are displayed. However, the present invention is not limited to this. For example, only the message 78 is displayed first, and the screen is displayed so that the message 80 is displayed at a predetermined timing. It may be switched. Further, by performing an operation such as touching the display of the electric device on the display 52A, the floor plan 66 (see FIG. 8) of the house 10 is simplified and displayed on the display 52A, and the installation position of the electric device is clearly indicated. Anyway. The simplified display at this time may be any display that allows the resident to specify the installation position of the electric device.

  FIG. 10B shows the case where there is one selected electrical device, but when there are a plurality of electrical devices of the same level, each may be displayed on the display 52A. FIG. 10C shows a display screen 76A as an example at this time. In this display screen 76A, since two “air conditioners A” and “air conditioners B” (for example, air conditioners 30A and 30B) are operating, messages 82A and 82B recommending that these air conditioners 30A and 30B be stopped. , 82C are displayed. At this time, the confirmation buttons 82D and 82E are displayed for each displayed electric device so that the electric devices to be stopped can be individually specified. However, the stop may be instructed with one confirmation button.

  In addition, in step 124 of FIG. 9, in addition to the display on the display 52A, the display content may be notified by voice from the speaker 52D, or an alarm indicating that an excessive power consumption is displayed may be issued.

  In the next step 126, it is confirmed whether or not the confirmation button 80A displayed on the display 52A has been operated (whether or not stop has been instructed), and in step 128, a message 80 or the like is displayed on the display 52A for a predetermined time. Check whether or not.

  Here, when the confirmation button 80A is operated, an affirmative determination is made in step 126, and the routine proceeds to step 130. If the confirmation button 80A is not operated even after the predetermined time has elapsed, an affirmative determination is made at step 128 and the routine proceeds to step 130.

  In step 130, the electric device (here, the air conditioner 30) displayed on the display 52A and recommended to stop is stopped. Thereafter, the process proceeds to step 118. At this time, the total power consumption Pc that has caused excessive power consumption may be stored.

  Although the displayed electric device is stopped by the resident confirming the display on the display 52A, the displayed electric device may be stopped without confirming the resident. In addition, when a priority is further set between electric devices having the same priority and a plurality of electric devices are displayed as electric devices having a low priority, the priority is low among the displayed electric devices. You may make it stop an electric equipment in order. At this time, the total power consumption Pc is calculated every time the electric device is stopped, and when the total power consumption Pc is equal to or less than the target consumption power Pm (Pc ≦ Pm), the operation stop of the next electric device is stopped. You may make it do.

  On the other hand, when an electrical device with a low priority is not operating and only a high priority (for example, level 1) is operating, a negative determination is made at step 122 and the routine proceeds to step 132. In step 132, the consumption target power Pm is temporarily increased. In step 134, in addition to the display for notifying that the power consumption is excessive, a display for recommending the review of the power consumption target Pm is performed. Here, when changing the consumption target power Pm, the process shown in FIG.

  FIG. 11 shows a display screen 84 as an example of display on the display 52 </ b> A based on step 134. On this display screen 84, a message 78 indicating excessive power consumption is displayed, and a message 86A indicating that there is no electrical device that can be stopped with a high priority of operating electrical devices. On the display screen 84, in addition to the current total power consumption Pc and target power consumption Pm (message 86B), a power consumption value Pmc recommended for review is displayed (message 86C). Here, the value (target value) of the target power consumption Pmc recommended to be reviewed can be a value slightly exceeding the total power consumption Pc at the time when the power consumption is excessive.

  The temporarily changed consumption target power Pm is returned to the original value when, for example, the next time shifts to the next time zone and the consumption target power Pm for that time zone is applied.

  As described above, in the monitoring control device 42, when only the electric devices set with high priority are operating, the problem caused by stopping those electric devices by not stopping the operating electric devices. Can be prevented in advance. That is, the lighting fixture 26 and the refrigerator 28 are set as high-priority electrical devices. For example, if the refrigerator 28 is stopped, the storage period of the food stored in the refrigerator 28 is shortened, or the frozen food is stored. Various problems such as defrosting occur, but such problems can be prevented from occurring.

  In addition, turning off the lighting fixture 26 at night causes anxiety to residents, but the occurrence of such a problem can be prevented by not turning off the lighting fixture 26. Note that the lighting fixture 26 often does not need to be lit in the daytime when the outdoors are bright. Band) and other time periods may have different priorities.

  Further, by temporarily increasing the target consumption power Pm, it is possible to prevent the same notification (alarm) from being continuously issued without stopping the electric device having a high priority.

  As described above, when the total power consumption Pc exceeds the consumption target power Pm, the supervisory control device 42 prompts the electric device to stop and suppress the power consumption, so the consumption target power Pm set by the resident is used. It is possible to suppress excessive power consumption. That is, since the occupant can arbitrarily set the target consumption power Pm on the monitoring control panel 42, power saving can be promoted if the occupant sets the consumption target power Pm low.

  In addition, the power consumption target Pm is set lower than the limit value such as contract power, so that when the power consumption is excessive, the main power breaker 34 can be activated by the total power consumption Pc reaching the contract power. It is possible to prevent the power supply to all the electric devices from being stopped by performing the blocking operation.

  In the first embodiment, it is recommended to change the target consumption power Pm when the total power consumption Pc exceeds the target consumption power Pm in a time zone in which only high priority devices are operating. The monitoring control panel 42 stores a history of the total power consumption Pc, and by referring to this history, the target power consumption Pm is lowered in a time zone where the total power consumption Pc is smaller than the target power consumption Pm. You may make a suggestion.

  For example, as shown in FIG. 7A, in the late-night time zone, the total power consumption Pc is lower than the target consumption power Pm. From here, the supervisory control panel 42 calculates the power of the difference between the total power consumption Pc and the target power consumption Pm, and displays it on the display 52A so as to reduce the target power consumption Pm in the midnight time zone. can do.

  Further, as shown in FIG. 7A, when the total power consumption Pc with respect to the target power consumption Pm is higher than the target power consumption Pm in the morning and evening hours, the electrical equipment with a low priority is used. By stopping the operation, power consumption (kwh) can be reduced.

[Second Embodiment]

  Next, a second embodiment of the present invention will be described. FIG. 12 shows an overview of the monitoring process according to the second embodiment. Note that the flowchart of FIG. 12 is applied instead of the flowchart of FIG. 9 according to the first embodiment, and the same processing is given the same step number and description thereof is omitted.

  In this flowchart, when the power consumption of the operating electric device is detected and the total power consumption Pc is calculated, in step 150, it is confirmed whether or not the total power consumption Pc exceeds the consumption target power Pm.

  Here, when one of the electric devices is operated, for example, when the total power consumption Pc exceeds the target consumption power Pm, an affirmative determination is made in step 150 and the process proceeds to step 152. In step 152, the display 52A displays that the total power consumption Pc has exceeded the power consumption target power Pm, and informs the resident. Further, in step 152, the electric device that has just started operating is displayed as the target electric device, and the target consumption power Pm is increased in accordance with the display (hereinafter also referred to as increasing the target consumption power Pm). Display to suggest. In step 154, the consumption target power Pm is provisionally increased (hereinafter, the increased consumption target power Pm is referred to as consumption target power Pms). Note that the increase amount at this time is a value at which the total power consumption Pc is equal to or less than the target power consumption Pms.

  In step 156, the installation position in the house 10 is read based on the device information of the target electrical device, and the installation position of the target electrical device is specified. Thereafter, in step 158, a display for prompting confirmation of whether or not to continue the operation of the target electrical device is performed. At this time, for example, the floor plan 66 of the house 10 is simplified and displayed on the display 52A, the position of the target electrical device is displayed on the floor plan, and whether or not the operation of the target electrical device is continued. Display to prompt confirmation.

  FIG. 13A shows an example of the display applied in step 152. The display screen 88 displayed on the display 52A displays a message 88A for notifying that the target electrical device (the electrical device that was operated immediately before) has been operated, and a message 88B for notifying that the power consumption has been excessive. To do. This message 88B includes a message proposing to temporarily increase (increase) the consumption target power Pm.

  In addition, a confirmation button 88C is displayed on the display screen 88, and when the confirmation button 88C is operated, the display on the display 52A is switched, and a display corresponding to the step 158 is made. FIG. 13B shows an example of display on the display 52A at this time. On this display screen 90, a message 90A for prompting confirmation of whether or not to continue the operation of the target electrical device is displayed, and a floor plan 92 obtained by simplifying the floor plan 66 of the house 10 is displayed. At this time, on the display screen 90, the mark 92A is displayed on the floor plan 92 so as to display the installation position of the target electrical device (in FIG. 13B, it is indicated by an asterisk as an example). Thereby, even when the electric device which a resident does not intend operates, confirmation of the electric device becomes easy.

  On this display screen 90, it is preferable to display a continuation button 90B for selecting to continue the operation of the target electrical device, whereby the operation is continued when the resident wants to operate the target electrical device urgently. It becomes possible to instruct as follows.

  On the other hand, in the flowchart of FIG. 12, it is confirmed in step 160 whether or not an instruction to continue the operation is given, and in step 162, it is confirmed whether or not a predetermined time has elapsed. Here, if the resident determines that the operation of the target electrical device is urgent and operates the continuation button 90B on the display screen 90 of the display 52A, an affirmative determination is made in step 160 and the processing proceeds to step 164. In step 164, the target consumption power Pm is set to be maintained at the increased state (target consumption power Pms).

  Thus, for example, the vehicle 24 is an electric vehicle, and the charger / discharger 24A is operated to urgently charge the storage battery of the vehicle 24, so that the vehicle 24 continues to be charged even when excessive power consumption occurs. can do. In this case, for example, when the target power consumption Pm that has not been increased is compared with the total power consumption Pc, and the total power consumption Pc is equal to or less than the target consumption value Pm that has not been increased (Pc ≦ Pm), Control such as returning the increased target consumption power Pms to the original can be applied.

  On the other hand, if there is no continuation instruction even after the predetermined time has elapsed, an affirmative determination is made in step 162 and the routine proceeds to step 166. In this step 166, an increase in the target consumption power Pm is set so as to continue for a predetermined time. That is, the target consumption power Pms is maintained for a predetermined time. In the next step 168, a time zone in which the total power consumption Pc is equal to or less than the target power consumption Pm (Pc ≦ Pm) is extracted (hereinafter also referred to as searching). That is, a search is made for a time zone in which the target electrical device can operate.

  In such a search for the time zone, since the history of the total power consumption Pc is stored in the monitoring control panel 42, a time zone in which the total power consumption Pc is lower than the target consumption power Pm is predicted using this history. You can This prediction is performed, for example, when the total power consumption Pcs obtained by adding the power consumption of the target electrical device to the stored total power consumption Pc is equal to or less than the target power consumption Pm, that is, the target power consumption Pm is the total power consumption. Search for a time zone that is greater than or equal to Pcs. At this time, for the total power consumption Pc applied to the calculation of the total power consumption Pcs, an average value can be calculated for each time zone, and this average value can be applied. The power consumption of the target electrical device can be obtained from the difference between the total power consumption Pc before the operation of the target electrical device and the total power consumption Pc during the operation of the target electrical device.

  Thereafter, in step 170, a display for prompting the operation of the target electrical device in the searched time zone is performed. Thereafter, when the predetermined time elapses, the consumption target power Pm that has been temporarily increased is returned to the original value, and the operation of the target electrical device is stopped (step 172).

  Here, for example, after 11 pm (23:00), the total power consumption Pc decreases, and until 5 am, the total power consumption Pcs is equal to or less than the target power consumption Pm for that time zone (Pcs ≦ Pm). If it is determined, the time zone from 11 pm to 5 am is acquired as a search result. The acquired time zone is displayed on the display 52A.

  FIG. 13C shows an example of display on the display 52 </ b> A in step 170. This display screen 94 displays a message 94A that suggests that the target electrical device be operated in the time zone acquired by the search. The display screen 94 is provided with a confirmation button 94B, for example, and the display is turned off by operating the confirmation button 94B. Further, the present invention is not limited to this, and it may be erased when a predetermined time elapses after the operation of the target electrical device is stopped.

  In this way, if the resident does not input the necessity of urgency, it is determined that there is no urgency, and after a predetermined time has elapsed, the operation of the target electrical equipment is stopped, thereby consuming electricity. To suppress the increase of In addition, by displaying the alternative time zone on the display 52A before the target electrical device is stopped, it is possible to prevent the resident from operating the target electrical device and causing excessive power consumption. .

  In step 154 of FIG. 12, the consumption target power Pm is provisionally increased without confirming the resident. However, the present invention is not limited to this. For example, on the display image 88 of FIG. When the resident operates the confirmation button 88C, step 154 may be executed to tentatively increase the consumption target power Pm. In this case, when the process proceeds to step 166, the consumption target power Pm may be temporarily increased.

In this way, including an increasing means for temporarily increasing the consumption upper limit target power value after the total power consumption value exceeds the consumption upper limit target power value, while the consumption upper limit target power value is increased by the increasing means, The notification means notifies the time period in which the total power consumption value is equal to or lower than the target power consumption value as the time period for operating the electric device that has been operated immediately before, so that the desired electric device is in a state where power consumption is suppressed. Can be operated accurately.
Moreover, in the house 10 which is the building according to the present embodiment, the consumption monitoring system 40 is provided, so that the resident can save energy in accordance with the target value of power consumption set by himself / herself.

  In addition, this Embodiment demonstrated above does not limit the structure of this invention. For example, in the present embodiment, the switch 54 is provided for the lighting fixture 26, but the switch 54 may be omitted if the lighting fixture 26 has the highest priority and there is no possibility of cutting off the power. In addition, any expression can be applied to various messages displayed on the display 52A as long as the intention is accurately transmitted.

  Further, in the present embodiment, it has been described that various messages are displayed on the display 52A so as to notify the resident. However, the present invention is not limited to this. Various notification means that can easily recognize the message can be applied.

  Furthermore, the configuration and control of the present embodiment described above are merely examples, and the present invention is not limited to the above, and can be variously modified and implemented without departing from the spirit of the present invention. Of course.
