Description

  The present invention relates to a notification device that notifies information so that a user can efficiently use a device by using power generated by a power generation device, a control method for the notification device, and a control program therefor.

  In recent years, it has become possible to generate electricity at home with the spread of power generation devices such as solar power generation devices and fuel cells.

  Of the power generated by the home solar power generation device, the power that has not been used up at home (surplus power) can be returned to the grid power and sold to the power company.

  When the amount of power sold from a large number of households increases and exceeds the range of power adjustment by an electric power company, it is conceivable that power sales from households are suppressed (reverse power flow suppression).

  In such a case, surplus power cannot be sold, so the user wants to use this surplus power at home as much as possible.

  In addition, if there is a power generation device, it is possible to live within the range of the power generated by the solar power generation device and to reduce the power purchased from the power company as much as possible.

  As described above, there is a need to use the electric power generated by the power generation device and the surplus power as much as possible at home. This applies not only to homes, but also to apartment houses, stores, offices, etc. equipped with power generation devices.

  Conventionally, for example, in Patent Document 1, in order to use nearly 100% of the power generated by a solar power generation device, the power generation predicted power and the electric device usage predicted power are displayed on a display device. Some of them tell the user which is more or less.

  In Patent Document 1, the generated power value and the consumed power value can be compared, but it is difficult for the user to know what can be done with the surplus power when the generated power value is larger and surplus. Met.

  For example, if the surplus power is displayed as 1 kWh, the user does not know what devices can be used with this power.

  If the user operates a device that requires more than 1 kWh, the surplus power will be purchased from the power company. In this case, the surplus power (electric power is free) It will generate an electricity bill to try to use it efficiently.

  The present invention has been made to solve the above problem, and provides a notification device, a notification device control method, and a control program for notifying a user of devices that can be used within the range of surplus power. It is the purpose.

  A notification device according to the present invention is necessary for a generated power acquisition unit that acquires information of a generated power value, a device group used power acquisition unit that acquires information of a used power value of a plurality of device groups, and an operation for each device. Device required power storage unit that stores information on the required power value, device state acquisition unit that acquires information on the operating state of each device, and the remaining power value obtained by subtracting the device group used power value from the generated power value (surplus power) An available device search unit that obtains a device whose operation state is not operating among devices whose required power value for each device is smaller than (value) from the device required power storage unit and outputs information on usable devices; An informing unit for informing information on the usable device output from the available device searching unit is provided.

  According to this configuration, the usable device search unit calculates the remaining power value (surplus power value) obtained by subtracting the device group used power value from the generated power value, and the non-operating device acquired by the device state acquisition unit The power required for the operation is acquired from the device required power storage unit, and a device having a smaller power required for the operation than the surplus power is notified as a usable device. Therefore, the user can use electric power within the range of surplus electric power by using the apparatus notified that it can be used.

  According to the present invention, a device that requires less power for operation than surplus power is notified as a usable device, so the user uses power within the range of surplus power by using the notified device. be able to.

  Embodiments of the present invention will be described below with reference to the accompanying drawings. In addition, the following embodiment is an example which actualized this invention, Comprising: It is not the thing of the character which limits the technical scope of this invention.

(Embodiment 1)
FIG. 1 is a diagram showing an overall configuration of a notification system according to Embodiment 1 of the present invention. The notification system shown in FIG. 1 includes a power generation device 1, a distribution board 2, outlets a, b, to z (3, 4, 5), home appliances a, b, to z (6, 7, 8), and A notification device 9 is provided.

  The power generator 1 is a distributed power generator such as a solar power generator, a wind power generator, a geothermal power generator, or a fuel cell.

  The distribution board 2 collects the power P1 (generated power value) generated by the power generator 1 and the power P2 (purchased power value) purchased from the grid power of the power company and supplies it to the equipment in the house or building To do. Here, in the present embodiment, it is assumed that the power generation cost of the power P1 generated by the power generation device 1 is lower than the power generation cost of the purchased power value purchased from the grid power.

  Hereinafter, although it demonstrates in a detached house, this invention is not limited to this. You may implement this invention in an apartment house, a store, an office, a factory, etc.

  The home appliances a to z are operated using electric power P1 + P2 supplied from the distribution board 2. Electric power is supplied from the distribution board 2 to the home appliances via the outlets 3 to 5.

  Here, the power used by the home appliance a is Pa, the power used by the home appliance b is Pb, and the power used by the home appliance z is Pz. This is the electric power consumption value for home appliances.

  The distribution board 2 has a built-in wattmeter or ammeter, and measures the power value supplied to all the home appliances a to z in the house to be P3. This is the power consumption value of the device group.

  The notification device 9a acquires and calculates the generated power value P1 generated by the power generation device 1, the purchased power value P2 from the grid power, and the device group used power value P3, which is the total used power in the home, and calculates the current home Can grasp the power situation. This may be displayed on a television or display monitor.

  For example, (A) When P2 = 0 and P1> P3, the electric power used by the home electric appliances of the house is supplied with the electric power generated by the electric power generation device 1. Since there is no electric power P2 purchased from the system, payment of the electricity bill does not occur. And the power of (P1-P3) is surplus as a surplus power value.

  In addition, when (B) P2> 0 and P1 + P2 = P3, it is not enough to supply the power used by the household electrical appliances with only the power generated by the power generator 1, and the power of P2 is purchased from the grid. Yes.

  Hereinafter, with respect to the above (A), an embodiment of the present invention will be described with reference to FIGS.

  In addition, in order to transmit / receive information among the power generation apparatus 1, the distribution board 2, the outlets 3-5, the household appliances 6-8, and the alerting | reporting apparatus 9a, each is wireless communication, PLC communication, wireless LAN communication, and wired LAN communication. Equipped with a communication device such as.

  When the notification device 9a is realized by a server device outside the house, the house and the server device are connected to the Internet using a public telephone line or a mobile data communication network.

  In addition, you may comprise the alerting | reporting apparatus 9a integrally with any of the distribution board 2, an electrical outlet, and household appliances.

  FIG. 2 is a block diagram showing in detail the configuration of the notification device 9a according to Embodiment 1 of the present invention. In addition, the electric power generating apparatus 1, the distribution board 2, and the household appliances 6 and 8 are the same as FIG.

  The generated power acquisition unit 21 acquires the generated power value P1 generated by the power generation device 1 and outputs it to the usable device search unit 25a. The power value may be an instantaneous value (power) or may be an integrated value (power amount) in a predetermined time unit. For example, the generated power at the present time may be used, or the amount of generated power until one hour after the current time may be predicted. Prediction of the amount of generated power may be predicted from the current operating state of the power generation apparatus 1 or past power generation history, or may be predicted by obtaining a weather forecast for solar power generation or wind power generation.

  The device group used power acquisition unit 22 acquires the device group used power value P3 supplied to the home electrical appliances in the house by the distribution board 2, and outputs the acquired device group used power value P3 to the usable device search unit 25a. The power value may be an instantaneous value (power) or may be an integrated value (power amount) in a predetermined time unit. For example, the power used at the present time may be used, or the power used for one hour after the current time may be predicted. The prediction of the amount of power used may be predicted from the current operating state of the home appliance group, or may be predicted from a past driving history.

  The device state acquisition unit 23a is connected to the home appliances a to z, acquires the state of each device, and outputs it to the usable device search unit 25a. As the state of the home appliance, it is information on whether or not the device is in operation, and information on when to start the operation when waiting for an operation reservation. Moreover, it is the information of the driving | running | working content at the time of driving | running | working, the completion | finish time of driving | operation, and the information of the sensor with which household appliances are mounted. These are acquired through communication between a control unit (not shown) of the home appliance and the device state acquisition unit 23a.

  In addition, if you want to obtain information on whether or not the home appliance is in operation, measure the power value used by the home appliance at an outlet that supplies power to the home appliance, and the power value is greater than or equal to a predetermined value. A method of determining that the vehicle is in operation may be used.

  The device required power storage unit 24a stores a home appliance name (identification information) in a house and a device list of power values necessary to drive the home appliance. The necessary power value may include the maximum power consumption value of the home appliance, the maximum power value necessary for each operation content and each driving course, and data of the operation time.

  For example, when the home appliance is an air conditioner, the maximum power consumption value differs between the cooling operation and the heating operation, so that the necessary power value is stored for each operation content. When the home appliance is a clothes washing and drying machine, the maximum power value and operation time when driving the washing course, the maximum power value and operation time when driving the dehydration course, the maximum power value when driving the drying course and Each operation time is stored individually. If the driving course that the clothes washing / drying machine is currently operating is known, the maximum power value and the driving time required for the subsequent driving can be calculated.

  For example, if the user selects the dehydration course + drying course and the dehydration course is in operation, the maximum power value required is the power of the maximum power value of the dehydration course and the maximum power value of the drying course. The one with the larger value. The total operation time of the dehydration course and the drying course is the maximum time. Furthermore, the remaining operation time can be calculated by acquiring the elapsed time from the start of driving the dehydration course and subtracting from this maximum time.

  The necessary power value may be an instantaneous value (power) or an integrated value (power amount) in a predetermined time unit. For example, the amount of electric power when the Ekon is operated for one hour and the amount of electric power and the operation time when the clothes washing and drying machine is operated once.

  The power value required to drive each home appliance in the house is measured in advance by the power supply used by the home appliance at the outlet for supplying power to the home appliance, even in the method of storing in the appliance required power storage unit 24a in advance. Alternatively, the maximum power consumption value may be stored.

  As described above, the generated power value P1, the device group use power value P3, the information on the operation state for each home appliance, and the necessary power value required for operation for each home appliance are input to the usable device search unit 25a.

  The available device search unit 25a detects when surplus power is generated, and searches for a device that can be used within the range of the surplus power.

  That is, the remaining power value (surplus power value) is calculated by subtracting the device group use power value P3 from the generated power value P1, and when surplus power is generated, the device that has not been operated and is acquired by the device state acquisition unit 23a. The power required for the operation is acquired from the device required power storage unit 24a, and if there is a device that requires less power than the surplus power, it is output to the notification unit 26 as a usable device.

  The power comparison means 28 detects the surplus power value by comparing the generated power value P1 and the device group used power value P3. The surplus power value is compared with the required power value of the device to search for a usable device.

  When there are a plurality of usable devices as a result of the search, the device list creating unit 29 creates a list of usable devices in consideration of user convenience.

  The notification unit 26 notifies the user of an available device list output from the available device search unit 25a. For example, display or voice guidance using a television, a personal computer, a remote controller, or a mobile terminal.

  The device operation unit 27 is an operation unit that allows the user to operate the home appliance by looking at the notification content of the notification unit 26, and the operation control information is transmitted to the corresponding home appliance. For example, when the user looks at the available device list and wants to start the operation of the clothes washing machine in the list, the user operates the device operation unit 27 to transmit an operation start command to the clothes washing machine. For this purpose, the user needs to prepare the clothes in the washing tub so that washing can be started anytime.

  This will be described with reference to FIG. 3 using a flowchart for explaining the operation of the notification system according to the first embodiment.

  First, in step S <b> 1, the usable device search unit 25 a acquires the generated power value P <b> 1 of the power generator 1 from the generated power acquisition unit 21. The generated power value P1 may be a current generated power value, or may be a generated power value for the past three hours or the past one day from the present accumulated in the generated power acquisition unit 21. Further, the generated power acquisition unit 21 stores the history of the power generation value accumulated on the same month last year, the history of the power generation value of the previous month, the previous day, and the history of the power generation value on the same weather if it is a solar power generation device. Using the current trend of the generated power value, the future generated power value from the present to the next six hours or one day ahead may be predicted and output to the usable device search unit 25a. In this case, the generated power value P1 is matrix data indicating the generated power value for each hour.

  In step S <b> 2, the usable device search unit 25 a acquires the device group used power value P <b> 3 of the distribution board 2 from the device group used power acquisition unit 22. The device group used power value P3 may be the current device group used power value, or the device group used power value for the past three hours or one day from the present accumulated in the device group used power acquisition unit 22. May be.

  Furthermore, the device group used power acquisition unit 22 stores the history of the device group used power value of the same month last year, the history of the device group used power value of the previous month, the previous day, the history of the device group used power value of the same day, Using the current trend of the device group power consumption value, the future device group power consumption value from the present time to six hours ahead or one day ahead may be predicted and output to the usable device search unit 25a. In this case, the device group used power value P3 is matrix data indicating the device group used power value for each hour.

  In step S <b> 3, the available device search unit 25 a compares the generated power value P <b> 1 and the device group used power value P <b> 3 by the power comparison unit 28 to calculate a surplus power value. That is, (P1-P3) is calculated. The surplus power value is matrix data obtained by calculating (P1-P3) for each time.

  In step S4, it is determined whether or not the calculated surplus power value is equal to or greater than a predetermined value (for example, 50 W or greater). If it is equal to or less than the predetermined value, the surplus power is determined to be small and the process returns to step S1.

  In step S4, when the calculated surplus power value is equal to or greater than a predetermined value (for example, 50 W or more), it is determined that the surplus power is large, and a device that can be used with the surplus power value is searched in step S5 and after. The predetermined value may be zero.

  First, in step S5, the usable device search unit 25a acquires information on the operation state for each device from the device state acquisition unit 23a. Here, the information is whether or not the device is in operation. In addition, if driving, information on the driving content and driving course is displayed.

  In step S6, referring to the device list stored in the required power storage unit 24a for devices not operating in the house (devices whose operation state is not operating), the power value (required power required) Value). Necessary electric power value for the operation details during operation (for example, air-conditioner cooling operation or heating operation) and for the operation course during operation (for example, washing, dehydrating or drying clothes washing dryer) to be completed by the end of operation Power value.

  In step S7, the power comparison means 28 compares the surplus power value with the required power value of the device to search for a device having a surplus power value larger than the required power value, that is, a usable device. .

  At this time, when the power comparison means 28 compares the surplus power value with the required power value of the device, the difference between the surplus power value and the required power value is not less than a predetermined value (for example, 50 W or more), and there is a margin. May be allowed.

  In step S8, the device list creation means 29 creates a device list of usable devices. At this time, referring to the device list stored in the necessary power storage unit 24a, the device list of usable devices is created in order from the device having the largest power value (necessary power value) necessary for operation. By creating a device list with priority given to devices with large required power, it is possible to operate within the range of surplus power, letting the user know from the device with the largest required power value as much as possible, and using much power within the surplus power range can do.

  In other words, there are many home appliances in the home, and many home appliances can be operated within the range of surplus power, but if there is not enough surplus power to operate all the home appliances, You may be wondering if you should drive the equipment. As a method for selecting a device in such a case, it is conceivable to preferentially operate a device having a large required power. This is because a device with a large operating power value cannot be operated with surplus power unless the surplus power is large.

  In step S9, the list of usable devices created by the device list creating unit 29 of the usable device searching unit 25a is output to the notification unit 26.

  In step S10, the notification unit 26 notifies the user. At this time, the surplus power value (P1-P3) may be output to the notification unit together with the list of usable devices. The notification unit 26 notifies the necessary power value necessary for operating the device with respect to the usable device, and also notifies the surplus power value. The user can operate the device by seeing the required power value and the surplus power value, and grasping the margin when the device is operated within the range of the surplus power value and the remaining surplus power value.

  The notification example will be described with reference to FIGS. Here, the power is displayed and described, but the power value may be displayed.

  FIG. 4 shows an example of display on a television or personal computer.

  On the left side of FIG. 4, home appliances that are not in operation are displayed in descending order of the required power value. This is a device list in order of devices having a large required power value generated and output in steps S5 to S9 in FIG. In FIG. 4, devices having a required power value larger than the surplus power value are also displayed in the device list, but only devices having a required power value smaller than the surplus power value may be displayed as in step S7.

  Also, the surplus power value is displayed on the right side of FIG. Then, the magnitude relationship between the required power value of the device list displayed on the left side and the surplus power value displayed on the right side is clearly shown, for example, by an arrow in FIG. 4 to inform the user of the devices that can be used with the surplus power. be able to. When the surplus power value increases, the number of devices that can be used increases in the device list, and when the surplus power value increases, it indicates that a device with a large required power value cannot be used.

  For example, as shown in FIG. 4, when the surplus power value is 960 W, as a device that can be used with this surplus power value, a washing dryer (all processes from washing to drying), a futon dryer, a humidifier, a washing dryer (laundry) It is understood that it is a liquid crystal television. If it is 960W or less, the entire process can be carried out from washing to drying with a washing / drying machine, or, from washing to dehydration, a futon dryer, humidifier, and LCD TV are used in combination with the washing / drying machine. You can see that

  In this way, when the user compares the required power amount of the usable device and the surplus power value obtained by subtracting the device group used power value from the generated power value, and operates the device within the surplus power range It is possible to operate the apparatus by grasping the degree of margin and the remaining surplus power value.

  Moreover, it turns out that a vacuum cleaner, a coffee maker, a dishwasher, etc. which are apparatuses with a required electric power value larger than a surplus electric power value cannot be used. The user compares the required power value and the surplus power value for the unusable device and the usable device, and knows the difference between the necessary power value and the surplus power value between the usable device and the unusable device. be able to.

  As shown in FIG. 4, by displaying a device list in which necessary power values are arranged in order of magnitude, the user can compare the power values used by the devices. Then, by making it possible to compare the power value of the usable device and the unusable device with the surplus power value, it is possible to link the surplus power, which is difficult to obtain, to the actual operation.

  FIG. 5 shows an example of display on a display terminal such as a remote controller or a portable terminal.

  The left side of FIG. 5 is a list in order of the required power value for home appliances that are not in operation, and a part of this is displayed on the display terminal as shown in the right side of FIG. 5 where the required power value is close to the surplus power value. To do. The surplus power value is fixed and displayed at the center, and the device displayed above the surplus power value cannot be used, and the device displayed below the surplus power value is usable. When the surplus power value changes, the device list changes.

  For example, in FIG. 5, the device is displayed with the surplus power value set to 960 W, but the displayed device changes when the surplus power value reaches 1300 W. Above the surplus power value, the toaster and hot plate are displayed as devices that cannot be used, and below the surplus power value, the dryer is displayed as a device that can use the dishwasher.

  Although not shown in FIG. 3, the operation control information of the device is included in the available device list output from the available device search unit 25a, and the user can be notified of the available device by the notification unit 26 and used. It may be possible for the user to select whether or not to start the operation of a possible device. When the user recognizes the start of operation, the operation control information is transmitted from the device operation unit 27 to the corresponding home appliance (that is, a device that can be used within the range of surplus power) to start the operation.

  For example, a washing / drying machine, a dishwasher, a garbage disposal machine, etc. are used by the device operation unit 27 so that the user sets the operation in advance and starts operation when it becomes available with surplus power. If the person sets in advance, the operation can be started with the generation of surplus power.

  It should be noted that after notifying the usable device in step S10, returning to step S1 again, even if the user operates the usable device, the surplus power is still sufficient and other household appliances are operated. In such a case, the user can be notified of the usable device again.

  Alternatively, the flowchart of FIG. 3 may be executed periodically (for example, at intervals of 10 minutes).

  By the way, another operation | movement of the alerting | reporting system in this Embodiment 1 which estimates a surplus electric power value is demonstrated with the flowchart of FIG.

  Since the block diagram showing the configuration of the notification device 9a in detail is the same as that shown in FIG.

  Steps S1 to S6 and S8 to S10 are the same as those in the flowchart of FIG.

  In FIG. 3, the surplus power value is calculated in S3 by subtracting the device group use power value P3 from the generated power value P1. In FIG. 6, the surplus power value is predicted in step S61.

  In step 61, it is necessary in the future predicted from the current operation by referring to the device list stored in the required power storage unit 24a for the device operating in the house (the device whose operating state is operating). A correct power value (required power value). The usable device search unit 25a acquires the operation content and driving course information during operation in the required power storage unit 24a for the operation state information for each device from the device state acquisition unit 23a acquired in step S5. Refer to the list and obtain the power value (required power value) necessary for operation.

  Necessary electric power value for the operation details during operation (for example, air-conditioner cooling operation or heating operation) and for the operation course during operation (for example, washing, dehydrating or drying clothes washing dryer) to be completed by the end of operation Power value can be obtained.

  Then, instead of the device group used power value acquired in S2, the available device search unit 25a obtains the total value of the required power values of the operating devices. That is, instead of the measured power consumption value, the maximum power consumption value of the operating device is predicted using the power requirement value stored in the device power requirement storage unit 24a.

  In step S71, the predicted value of the necessary power value is subtracted from the generated power value P1 to obtain a surplus power value, and the surplus power value is compared with the necessary power value of the device by the power comparison means 28 to obtain the necessary power. A device having a surplus power value larger than the value, that is, a usable device is searched.

  As described above, by the operation of the flowchart of FIG. 6, the usable device search unit 25 can increase the accuracy of the surplus power value and notify the user of a more reliable usable device.

  As described above, the first embodiment of the present invention has the following effects.

  (1) The usable device search unit calculates the remaining power value (surplus power value) obtained by subtracting the device group used power value from the generated power value, and operates the non-operated device acquired by the device state acquisition unit. Is acquired from the device required power storage unit, and a device having a smaller power required for operation than the surplus power is notified as a usable device. Therefore, the user can use electric power within the range of surplus electric power by using the apparatus notified that it can be used.

  (2) The notification unit gives priority to a device having a large required power value for each device, and reports information on usable devices. And a user can use much electric power within the range of surplus electric power because a user operates the apparatus with a large required electric power value alert | reported preferentially.

  (3) In addition, the notification unit notifies the required power amount of the usable device and the surplus power value obtained by subtracting the device group used power value from the generated power value in a comparable form. The user then compares the required power value of the usable device with the surplus power value, and grasps the margin when the device is operated within the surplus power range and the remaining surplus power value, and determines the device. Can be driven.

  (4) In addition, the notification unit notifies the device information about the devices other than the usable device among the devices that are not in operation, in order of the required power value, and can be compared with the surplus power value. Inform in form. Then, the user compares the necessary power value and the surplus power value for the unusable device and the usable device, and the difference between the necessary power value and the surplus power value between the usable device and the unusable device. Can know.

(Embodiment 2)
In the first embodiment, a usable device is notified, but in addition to this, the operating notification unit measures and notifies the power usage value of the operating device. And the power usage value of the apparatus in operation is notified together with the surplus power value. By notifying the amount of power used by the operating device, the user can know the surplus power value that increases when the operating device is stopped. The present invention will be described in the embodiment.

  FIG. 7 is a block diagram showing an overall configuration of a notification system according to Embodiment 2 of the present invention.

  The difference from Embodiment 1 (FIG. 1) is that in FIG. 7, home appliances a to z are supplied with power from distribution board 2 through outlets 3 to 5, and power meters or Built-in ammeter measures the power consumption for each device. The outlets 3 to 5 are connected to the notification device 9b and transmit the measurement values Pa, Pb, and Pz.

  Here, the power used by the home appliance a is Pa, the power used by the home appliance b is Pb, and the power used by the home appliance z is Pz. This is the electric power consumption value for home appliances.

  Further, instead of incorporating a power meter in the outlet, a method of measuring the power for each outlet by the distribution board 2 by supplying power from the distribution board 2 for each outlet is also conceivable. Or you may measure by incorporating the wattmeter in the household appliance main body.

  Next, FIG. 8 is a block diagram showing in detail the configuration of the notification device 9b according to Embodiment 2 of the present invention.

  A different point from Embodiment 1 (FIG. 2) is demonstrated.

  In FIG. 8, the device state acquisition unit 23b is connected to the home appliances a to z, acquires the home appliance use power (Pa to Pz) together with the state of each device, and outputs it to the available device search unit 25a. .

  And the apparatus state acquisition part 23b outputs household appliances use electric power (Pa-Pz) to the apparatus required power storage part 24b with the status information of an apparatus, and the apparatus required power storage part 24b has memorize | stored in the house Update the device list of the home appliance name (identification information) and the power value required to operate the home appliance. In other words, the device required power storage unit 24b updates the required power value by using the measured electric power consumption (Pa to Pz) of home appliances in the operation content and operation course during operation obtained from the operation state information of the device. be able to.

  In addition, the usable device search unit 25b outputs the device list during operation to the notification unit 26 together with the usable device list. The operating device list is a list including an operating state of the operating device and the power consumption value of the device.

  Next, FIG. 9 is demonstrated with the flowchart for demonstrating operation | movement of the alerting | reporting system which concerns on Embodiment 2 of this invention.

  A different point from Embodiment 1 (FIG. 3) is demonstrated.

  First, in step S51, the usable device search unit 25b acquires information on the operation state for each device and the power used for each device (device power consumption value) from the device state acquisition unit 23b.

  And in step S62, with reference to the apparatus list memorize | stored in the required power storage part 24b about the apparatus which is not drive | operating in a house (operating state is not drive | operating), the electric power value required for driving | operation (( (Required power value) is acquired.

  In addition, the device required power storage unit 24b acquires information on the operating state of the device and the power usage value of the device operating in the house (the device whose operating state is operating), and the above-described necessity Update the list of power values. When the device power consumption value exceeds the stored power consumption amount, the necessary power amount is rewritten to the device power consumption value. This is performed in the information (operation content, driving course) of the corresponding driving state.

  By storing the measured device power consumption value in the required power storage unit 24b in this way, it is possible to notify a device that can be used with surplus power using the required power amount according to the actual usage at home.

  In step S91, the device list for the currently operating device is created by the device list creating means 29 in the device list for the currently operating device in the same manner as the device list for the available device. At this time, referring to the device power consumption value, the devices are used in order from the device with the largest power value.

  In step S11, the notification unit 26 notifies the device list of the currently operating device together with the surplus power value and the available device list. This currently operating device list reports the operating state information and the device power consumption value for the device being operated. The user looks at the surplus power value, the required operating power value for each device, and the device power consumption value of the operating device, and compares the surplus power value with the device power consumption value to determine the size of the surplus power value. Or by comparing the required operating power value and the device operating power value, it is possible to grasp that a plurality of usable devices can be used when the operating device is stopped.

  An example of the notification will be described with reference to FIG. Here, the power is displayed and described, but the power value may be displayed.

  FIG. 10 shows an example of display on a television or personal computer.

  On the left side of FIG. 10, for household electrical appliances in the home, devices that are not in operation display necessary power values, and devices that are in operation display power consumption values in descending order. This is information on the usable devices and the devices in operation created and output in steps S51 to S91 in FIG. In FIG. 10, devices having a required power value larger than the surplus power value are also displayed in the device list, but only devices having a required power value smaller than the surplus power value may be displayed as in step S7.

  Then, as in FIG. 4, the surplus power value is displayed on the right side, and the magnitude relationship between the required power value of the device list displayed on the left side and the surplus power value displayed on the right side is clearly shown. As shown in FIG. 10, the device is used by the device by displaying a device list in which the power values used by the devices in operation and the power values required by the devices not in operation are arranged in order of size. The magnitude of the power value can be compared. Then, by making it possible to compare the power value and surplus power value of the operating device, the usable device, and the unusable device, it is possible to link a surplus power value that is difficult to obtain to the actual operation.

  In this way, since the power usage value and surplus power value of the operating device are informed in a comparable form, the user compares the power usage value of the operating device with the surplus power value and is operating. It is possible to know the surplus power value that increases when the device is stopped.

  In addition, you may alert | report FIG. 10 in a display terminal like FIG.

  As described above, the second embodiment of the present invention has the following effects.

  (5) The device state acquisition unit acquires the power consumption value for the device whose operation state is in operation, and the notification unit notifies the power consumption value and surplus power value of the device being operated in a comparable form. Then, the user can know the surplus power value that increases when the operating device is stopped by comparing the used power value of the operating device with the surplus power value.

  In the first and second embodiments, although not shown, the device list creation unit 29 may create the device list in order of frequency of use, for example, in consideration of the priority of the devices.

  Information on priority and usage frequency of the device is stored in the device required power storage unit 24 together with the required power value for each device, as well as information on priority and usage frequency. These priorities may be set in advance by the user in the device required power storage unit 24, or the device required power storage unit 24 counts the frequency of use using information on the operating state obtained from the device state acquisition unit 23. You may make it create and update.

  An example of notification is shown in FIG. It gives notification that surplus power can be used, giving priority to dishwashers, coffee makers, and vacuum cleaners that are frequently used.

  As a result, (6) the device required power storage unit stores the information on the frequency of use for each device together with the required power value for each device, and the usable device search unit can preferentially use a device with a high frequency of use for each device. Output device information. And since the apparatus with a high usage frequency is preferentially alert | reported about the apparatus which can be used, surplus electric power can be used for an apparatus with a high usage frequency.

  Of course, the device list creation means may create the device list for the device list that is currently in operation, for example, in descending order of use frequency in consideration of the device priority.

(Embodiment 3)
In the first and second embodiments described above, usable devices are notified. However, if there is a desire for a device that the user wants to use, this can be input and notified preferentially. The present invention will be described in a third embodiment.

  FIG. 12 is a block diagram showing an overall configuration of a notification system according to Embodiment 3 of the present invention.

  Although the measurement of the power usage values Pa to Pz of the home appliances 6 to 8 will be described as being performed by the main body of each home appliance, it may be a mode of measuring at the outlets 3 to 5 as in the second embodiment (FIG. 7). . The power usage values Pa to Pz of the household electrical appliances 6 to 8 are acquired from the device status acquisition unit of the notification device 9c to the usable device search unit 25c in the same manner as in the second embodiment.

  In addition, although the power usage value of the device measured in the second embodiment is stored in the device required power storage unit 24b, this is not essential in the third embodiment. Also, measurement and storage of the usage frequency of the device are not essential for the third embodiment.

  Next, FIG. 13 is a block diagram showing in detail the configuration of the notification device 9c according to Embodiment 3 of the present invention.

  A different point from Embodiment 2 (FIG. 8) is demonstrated.

  In FIG. 13, the notification device 9 c includes a desired device setting unit 30 and receives a request for a device that the user wants to use.

  Then, the usable device search unit 25c outputs usable information to the notification unit 26 to notify the user when the device desired by the user (desired device) can be used within the range of the surplus power value. .

  Further, when the desired device cannot be used within the range of the surplus power value, the user is informed that the device can be used by stopping the operation of the operating device.

  FIG. 14 is described with the flowchart for demonstrating operation | movement of the alerting | reporting system which concerns on Embodiment 3 of this invention.

  A different point from Embodiment 2 (FIG. 9) is demonstrated.

  In step S12, a desired device set by the user (a device that is to be operated within the range of surplus power) is received. Here, it is assumed that information on a desired device such as a necessary power value necessary for operation of the desired device is stored in advance in the device required power storage unit 24a.

  In step S13, the usable device search unit 25c acquires the required power value of the desired device from the device required power storage unit 24a. In step S14, the surplus power value calculated in step S3 and the required power value of the desired device. And compare.

  When the surplus power is larger than the required power value of the desired device, the desired device can be used within the surplus power range, and this is notified to the user. In step S17, the usable device search unit 25c outputs usable information indicating that the device desired to be used is usable together with the usable device list to the notification unit 26, and notifies the user in step S18. . For example, inform the user that the desired device is available.

  When the surplus power is smaller than the required power value of the desired device, the desired device cannot be used within the surplus power range. Therefore, the available device searching unit 25c calculates a value obtained by subtracting the necessary power value of the desired device from the surplus power value, thereby obtaining a power value (insufficient power value) that is not sufficient for using the desired device. If the shortage value can be covered by calculating and stopping the currently operating device, the user is informed of this.

  In step S15, the power comparing means 28 compares the insufficient power value with the used power value of the currently operating device and searches for a device having a larger used power value than the insufficient power value. Here, the power usage value of the currently operating device is obtained from the device state acquisition unit 23b.

  Next, in step S <b> 16, the device list creation unit 29 creates a device list of devices having a power usage value larger than the insufficient power value. At this time, with reference to the device power consumption value of the device in operation, the devices are created in order from the device with the largest power value. This device list becomes usable information.

  In step S <b> 18, the notification unit 26 notifies the useable information for using the desired device together with the available device list. The availability information includes information on whether or not the desired device can be used within the range of surplus power, and which of the currently operating devices that can be used if it cannot be used if it cannot be used. This is a device list. This device list is notified in descending order of the power value being used.

  Note that steps S4, S6, S7, and S8 may not be performed, and the creation of a device list of usable devices may be omitted.

  A notification example when the surplus power is smaller than the required power value of the desired device (NO in step S14 of FIG. 14) will be described with reference to FIG. Here, the power is displayed and described, but the power value may be displayed.

  FIG. 15 shows an example of display on a television or personal computer.

  On the left side of FIG. 15, the household appliances in operation are displayed in descending order of the power consumption value. This is the device list in the order of devices having the largest power usage values created and output in steps S15 to S16 in FIG. In FIG. 15, devices having a power consumption value smaller than the power shortage value are also displayed in the device list, but only devices having a power consumption value larger than the power shortage value may be displayed as in step S15.

  In addition, an insufficient power value is displayed on the right side of FIG. Then, the magnitude relationship between the power consumption value displayed in the device list displayed on the left side and the power shortage value displayed on the right side is clearly shown. For example, by using an arrow in FIG. Therefore, it is possible to inform the user of a device effective for stopping the operation. When the power shortage value becomes smaller, the number of devices that are effective to be stopped increases in the device list, and when the power shortage is increased, the number of devices that are effective to stop operation is reduced.

  For example, as shown in FIG. 15, it is assumed that the surplus power value is 960 W and that 140 W is insufficient to use the dryer that is the desired device. As a device that is effective to stop operation in order to obtain this insufficient power, a heating toilet seat, a television in the living room, and the like are known. In addition, the operating state of the operating device acquired by the notification device is also displayed. For example, the rice cooker is finished in 10 minutes and the set temperature of the air conditioner.

  In addition, when the power shortage is large, for example, at 1000 W, it can be seen that the operation of the rice cooker may be completed or it is effective to stop the operation of the heating toilet seat and the two devices of Kotatsu. .

  It can also be seen that the dryer cannot be used even if the operation of the air cleaner or the recorder, which is a device having a power consumption value smaller than the insufficient power value, is stopped.

  As shown in FIG. 15, by displaying a device list in which power values in use are arranged in order of magnitude and making it comparable to the power value that is insufficient, surplus power can be obtained even when the surplus power alone is insufficient. A method of using the device within the range of is obtained. A surplus power value that is difficult to obtain can be linked to actual operation.

  In addition, you may alert | report FIG. 15 like FIG. 5 in a display terminal.

  Now, although not shown in FIG. 14, by including the operation stop information of the device in the usable information for using the desired use device output from the usable device search unit 25c, the notification unit 26 stops the operation. While notifying the user of a device that the desired device can use, the user may be able to select whether or not to stop the operation of the device. When the user accepts the stoppage of operation, the operation is stopped by transmitting the operation stop information from the device operation unit 27 to the corresponding home appliance (that is, the device that can be used by stopping the operation). Let

  As described above, the third embodiment of the present invention has the following effects.

  (7) The notification device includes a desired device setting unit that sets a device (desired device) that the user desires to use among devices stored in the device required power storage unit, and the available device search unit has an excess power value. When it becomes larger than the required power value of the desired device, it outputs usable information to the notification unit for notification. Then, the user can set a device that he / she wants to operate with surplus power and know that the device can be used.

  (8) The device state acquisition unit acquires the power consumption value for the device whose operation state is in operation, and when the required power value of the desired device is larger than the surplus power value, the usable device search unit calculates from the required power value. The remaining power value (shortage power value) obtained by subtracting the surplus power value is calculated, and a device having a power consumption value larger than the shortage power value is acquired from the device state acquisition unit and is notified to the notification unit. Then, in order to make the desired device usable, the user can know which device in operation should be stopped.

  In addition, you may implement invention with the program which implement | achieves the alerting | reporting apparatus 9 of this Embodiment 1-3 with a computer.

  Finally, application of the inventions of the first to third embodiments will be described.

  In this Embodiment 1-3, the electric power value P1 which generate | occur | produces from the electric power generating apparatus 1 was used, and the apparatus which can be drive | operated within the range of a surplus electric power value on condition that the purchased electric power value P2 from a system | strain does not generate | occur | produce was notified.

  Consider a case where surplus power can be sold as in the notification system shown in FIG. Whether it is economical to use surplus power in equipment or to sell electricity depends on the unit price of purchased power and the unit price of sold power.

  If purchased power is more expensive than sold power, it is economical to reduce the purchased power by using surplus power in the device. Therefore, it becomes possible to inform the user that the surplus power is used in the operation of the equipment as in the first to third embodiments.

  Conversely, if the purchased power is cheaper than the sold power, it is economical to sell the surplus power and increase the sold power. Considering this case in FIG. 16, the power sale power value P4 is obtained by subtracting the device group use power P3 from the generated power value P1.

  However, when the power sale power increases, there is an allowable value for the equipment on the side that purchases the surplus power, and if the allowable value is exceeded, the surplus power cannot be sold any more. Suppression of reverse power flow occurs.

  If this case is considered in FIG. 16, the remainder of (generated power value P1—equipment group power use P3—power sales power P4) is generated as surplus power that cannot be sold. By replacing the surplus power that cannot be sold with the surplus power of the first to third embodiments, it is possible to notify the user of how to use the surplus power that cannot be sold in equipment operation.

  As described above, the present invention is useful in a system capable of selling surplus power.

  Also, consider a case where the power storage device 10 such as a storage battery is provided as in the notification system shown in FIG. 17 and the power generated by the power generation device 1 or the power purchased from the system can be stored.

  According to this configuration, when the power generated by the power generation device 1 remains in the house without being used up, the power can be stored in the power storage device 10. The power storage device 10 temporarily stores power, and the stored power is eventually discharged and used in equipment in a house. This is because if the stored power is not discharged at some point in the future, the power storage device is fully charged, and no more power can be stored. That is, the power stored in the power storage device 10 (power storage power value) can be handled as future surplus power.

  Considering this case in FIG. 17, (generated power value P1 + accumulated power value P5−equipment group power use P3) is set as surplus power. In addition, when there is no power generation by the power generation device, (accumulated power value P5—equipment group power consumption P3) is set as surplus power. By replacing this surplus power with the surplus power of the first to third embodiments, it is possible to inform the user how to use the surplus power including the power stored in the storage battery in device operation. The power storage device 10 may be a storage battery of an electric vehicle that can be connected to a home and charged and discharged.

  As described above, the present invention is useful in a system including a power storage device.

  In addition, when a power value (allowable power value P6) that can be purchased from an electric power company is determined in a home where no power generator exists, as in the notification system shown in FIG. Then, when operating the device, the user is allowed to use as many devices as possible within the allowable power range by replacing the allowable power value P6 with the surplus power of the first to third embodiments. It becomes possible to inform.

  As described above, in the present embodiment, an example of an electric device has been described with a home electric appliance at home, but the present invention is not limited to this, and the same effect can be obtained with an electric device handled in an office, factory, facility, or the like. .

  Further, the present invention may be distributed as a program by a storage medium or a communication medium, installed in a server, a personal computer, or a microcomputer of an electric device and executed as a device control apparatus.

  The notification device, the control method of the notification device, and the control program according to the present invention can notify devices that can be operated within the range of surplus power, and are useful for efficient operation of electrical devices.
