The wireless communication unit 21 includes a wireless communication interface, and performs wireless data communication with the operation terminal 3, the power measurement device 4, and each device 5 under the control of the control unit 23.

The data storage unit 22 includes, for example, an EEPROM (Electrically-Erasable-Programmable-Read-Only Memory), a readable / writable nonvolatile semiconductor memory such as a flash memory, a hard disk drive, and the like. As illustrated in FIG. 3, the data storage unit 22 stores a power DB 220, a device DB 221, power usage pattern data 222, and an operation schedule table 223. In addition to this, the data storage unit 22 is used when a program for monitoring the power consumed at home, a program for controlling the operation of each device 5, and the execution of these programs.

The power DB (power database) 220 is a database in which a history of measurement results is stored for each power line. The control unit 23 updates the power DB 220 based on the measurement data from the power measurement device 4 acquired at regular time intervals.

The device DB (device database) 221 is a database in which a history of operation states is stored for each device 5. The operation state includes, for example, a power supply state (power on / off), operation presence / absence (during operation / stop), operation mode, setting information, and the like. For example, in the case of an air conditioner, the operation mode includes cooling, heating, air blowing, dehumidification, and the like, and in the case of a rice cooker, rice cooking, heat retention, and the like are applicable. The setting information corresponds to a set temperature (also referred to as a target temperature) in an air conditioner or the like, an air volume, and the like. The control unit 23 updates the device DB 221 based on the operation state data from each device 5 acquired at regular intervals.

The power usage pattern data 222 is data indicating a power usage (power consumption) pattern for a predetermined period predicted (estimated) in this home. In the present embodiment, the power usage pattern data 222 is data indicating a predicted transition of power consumption for one day (24 hours). The power usage pattern data 222 is generated by the control unit 23 at a predetermined daily time (for example, midnight) and stored in the data storage unit 22.

The operation schedule table 223 is a data table indicating an operation schedule of each device 5 in a predetermined period. In the present embodiment, a record indicating an operation schedule for one day (24 hours) of each device 5 is registered in the operation schedule table 223. In the operation schedule of each device 5, the start time and end time of operation and the operation state are stored in association with each other. The operation schedule table 223 is generated by the control unit 23 at a predetermined daily time (for example, midnight) and stored in the data storage unit 22.

The control unit 23 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like (all not shown) and controls the control device 2 in an integrated manner. As shown in FIG. 4, the control unit 23 includes a user interface processing unit 230, a measured power acquisition unit 231, an operation state acquisition unit 232, a power usage pattern generation unit 233, an operation schedule generation unit 234, and an event acquisition. A unit 235, a mode switching unit 236, a device list generation unit 237, a calculation unit 238, a display instruction unit 239, a control pattern acquisition unit 240, and a device control unit 241. The functions of these components are realized by the CPU executing a program stored in the data storage unit 22.

The user interface processing unit 230 performs user interface processing via the operation terminal 3. That is, the user interface processing unit 230 receives an operation from the user via the operation terminal 3 and the wireless communication unit 21. Further, the user interface processing unit 230 transmits information (for example, monitoring screen data and various operation screen data) to be presented to the user to the operation terminal 3 via the wireless communication unit 21.

The measured power acquisition unit 231 performs processing for acquiring the measured power value from the power measurement device 4. Specifically, the measured power acquisition unit 231 requests the power measurement device 4 to transmit the measurement data of each power line at a constant time interval (for example, every 30 seconds). In response to the request, the measured power acquisition unit 231 acquires measurement data for each power line transmitted from the power measurement device 4 via the wireless communication unit 21. The measured power acquisition unit 231 updates the power DB 220 based on each acquired measurement data.

The operation state acquisition unit 232 performs processing for acquiring the operation state from each device 5. Specifically, the driving state acquisition unit 232 requests each device 5 to transmit driving state data at a constant time interval (for example, every 30 seconds). The driving state acquisition unit 232 acquires the driving state data transmitted from each device 5 through the wireless communication unit 21 in response to the request. The operation state acquisition unit 232 updates the device DB 221 based on the acquired operation state data of each device 5.

The power usage pattern generation unit 233 generates power usage pattern data 222 with reference to the contents of the power DB 220 at a predetermined time every day (for example, midnight). For example, the power usage pattern generation unit 233 may estimate the transition of power consumption on the previous day as the transition of power consumption for today in this home. Alternatively, the transition of power consumption may be predicted by obtaining the average of the transition of power consumption for the past week, the average of the transition of past power consumption on the same day of the week as the current day, or the like.

The operation schedule generation unit 234 generates the operation schedule table 223 with reference to the contents of the device DB 221 at a predetermined time every day (for example, midnight). For example, the operation schedule generation unit 234 may estimate the operation schedule of each device 5 today based on the operation status of the previous day of each device 5. Alternatively, today's driving schedule of each device 5 may be estimated based on the driving situation for the past week or the past driving situation on the same day of the week as the current day.

The event acquisition unit 235 (event data acquisition means) communicates with the server 9 via the wide area communication unit 20 and receives a notification (DR notification) about DR (Demand Response) from the server 9. The server 9 is a so-called cloud server for HEMS that is managed by a vendor or the like of the control device 2. When the server 9 receives a DR notification from a server managed by an electric power company or an organization (aggregator) entrusted to the electric power company, the server 9 transmits the DR notification to the control device 2 of the contracting user.

The DR notification includes information indicating the type of DR, information indicating the type of notification, and information indicating a target time zone (hereinafter referred to as an event time zone). Examples of the DR type include CPP (CriticalCPeak Pricing) and PTR (Peak Time Rebate). CPP indicates that the unit price of electricity charges in the event time zone soars. Also, PTR indicates that when the amount of power consumption is reduced during the event time period, a refund is made according to the amount of reduction. In the present embodiment, it is assumed that the DR notification of the type CPP further includes a unit price for electricity charges.

Also, there are three types of notification: “notice notification”, “decision notification”, and “cancellation notification”. The “notice notice” is a notice for notifying the implementation of the DR indicated by the DR type. The “determination notification” is a notification that the predicted DR is surely performed. This “determination notification” is transmitted from the server 9 about one hour before the start time of the event time zone. The “cancellation notification” is a notification that the implementation of the predicted DR has been canceled (cancelled), and is notified before the event time period.

When the event acquisition unit 235 acquires the DR notification from the server 9 via the wide area communication unit 20, the event acquisition unit 235 stores the received DR notification in the RAM or the data storage unit 22.

The mode switching unit 236 switches the control mode from the normal mode to the DR mode when the DR notification acquired by the event acquisition unit 235 is a notice notification. In addition, when the DR notification acquired by the event acquisition unit 235 is a cancellation notification, the mode switching unit 236 switches the control mode from the DR mode to the normal mode. Furthermore, in the DR mode, the mode switching unit 236 controls the control when no notification is received from the server 9 even before the predetermined time (in this embodiment, 10 minutes before) from the start time of the event time zone. The mode is switched from the DR mode to the normal mode.

When the control mode is switched to the DR mode, the device list generation unit 237 generates a list of devices 5 that can perform power saving control in the event time zone. Specifically, first, the device list generation unit 237 refers to the operation schedule table 223 and selects all the devices 5 that are scheduled to be operated in the event time zone and that can be subjected to power saving control. Note that “the driving is scheduled in the event time zone” means that the driving is scheduled in at least a part of the event time zone. Further, “power saving control is possible” means that operation with lower power consumption is possible than during operation based on the operation state scheduled in the operation schedule table 223.

When all the devices 5 that satisfy the above conditions are selected, the device list generation unit 237 records, for each selected device 5, a device name, a control content, and a scheduled operation time (scheduled usage time). Is generated and stored in the data storage unit 22. The device name indicates a general name / common name of each device 5 such as “air conditioner” and “floor cooling / heating”, for example, and information on each device 5 is displayed on the operation terminal 3, for example. At this time, it is used to enable the user to recognize which device 5 the device 5 is.

The control content indicates the content of power saving control, for example, “set temperature + 1 degree” for an air conditioner during cooling, “set temperature—1 degree” for an air conditioner during heating, and the like. When a plurality of power saving controls are possible for one device 5, a plurality of records with different control contents are registered in the device list data for the device 5.

As illustrated in FIG. 5, the calculation unit 238 includes a first calculation unit 2380, a second calculation unit 2381, a third calculation unit 2382, a fourth calculation unit 2383, a fifth calculation unit 2384, and a sixth calculation. Part 2385. When the control mode is the DR mode, the first calculation unit 2380 calculates the power consumption (estimated total power consumption) in the event time period based on the power usage pattern data 222 at regular intervals. The first calculation unit 2380 stores the calculated estimated total power consumption in the data storage unit 22.

When the control mode is switched to the DR mode, the second calculation unit 2381 calculates the power consumption amount during power saving control from the power consumption amount during non-power saving control in the event time zone for each device 5 indicated by the device list data. The subtracted power amount (estimated reduction power amount) is calculated. The power consumption amount (estimated power consumption amount) at the time of non-power saving control and power saving control is calculated by referring to the power DB 220 and the device DB 221 respectively. When a plurality of records having different control details are registered in the device list data for the same device 5, an estimated reduction power amount corresponding to each control content is calculated for the device 5. The second calculation unit 2381 stores the calculated estimated power reduction amounts in the data storage unit 22 in association with information (for example, device address) for identifying the device 5 and control content.

When the control mode is the DR mode, the third calculation unit 2382, based on the estimated total power consumption calculated by the first calculation unit 2380 and the electric charge data at regular time intervals, the electric charge in the event time zone Is calculated. The electricity rate data is data indicating an electricity rate unit price (unit price of electricity rate according to time zone) and the like, and is set in the control device 2 by the user via the operation terminal 3 and stored in the data storage unit 22. To do. Or the control apparatus 2 may acquire the electricity bill data by data communication from servers, such as the server 9 and an electric power company. The third calculation unit 2382 stores the calculated electricity bill in the data storage unit 22.

When the control mode is switched to the DR mode, the fourth calculation unit 2383 reduces the electricity bill corresponding to each device 5 based on each estimated reduction power amount calculated by the second calculation unit 2381 and the electricity bill data. Calculate the amount. Note that when a plurality of different estimated power reduction amounts are associated with the same device 5, a reduction amount corresponding to each estimated power reduction amount is calculated for the device 5. The fourth calculation unit 2383 stores each calculated reduction amount in the data storage unit 22 in association with information for identifying the device 5, the control content, and the estimated power reduction amount.

The fifth calculation unit 2384 calculates the total of each estimated reduction power amount (total estimated reduction power amount) calculated by the second calculation unit 2381 and stores the calculated total estimated reduction power amount in the data storage unit 22.

6th calculation part 2385 calculates the electricity bill (total reduction amount) equivalent to the total estimated reduction electric energy calculated by the 5th calculation part 2384. Note that the sixth calculation unit 2385 may acquire the total reduction amount by calculating the total of the reduction amounts calculated by the fourth calculation unit 2383. The sixth calculation unit 2385 stores the calculated total reduction amount in the data storage unit 22.

The display instruction unit 239 (display instruction unit) generates event information based on the content of the DR notification, the device list data generated by the device list generation unit 237, and the calculation result by the calculation unit 238, and generates the generated event The operation terminal 3 is instructed to display information. An example of a screen (event information screen) displayed on the operation terminal 3 in response to such an instruction is shown in FIG. As shown in FIG. 6, in the event information screen, a pattern in which the content of each record (device name, control content, scheduled usage time), estimated power reduction amount, and reduction amount in the device list data is associated ( Control pattern) is displayed. Each control pattern is provided with a check box, and the user can select a desired control pattern by checking the check box (see FIG. 7).

The contents of the control pattern selected by the user are acquired.

The device control unit 241 controls the device 5 included in the control pattern acquired by the control pattern acquisition unit 240 based on the scheduled usage time and the control content included in the control pattern.

FIG. 8 is a flowchart showing a procedure of event information display processing executed by the control unit 23 of the control device 2. This event information display process is started when the control mode is switched to the DR mode.

In step S101, the device list generation unit 237 generates device list data indicating a list of devices that can be controlled in the event time zone.

In step S102, the first calculation unit 2380 calculates the estimated total power consumption in the event time zone.

In step S103, the second calculation unit 2381 calculates the estimated power reduction amount according to the control content of each device 5 capable of power saving control in the event time zone.

In step S104, the third calculation unit 2382 calculates an electricity bill in the event time zone.

In step S105, the fourth calculation unit 2383 calculates a reduction amount of the electricity charge according to the control content of each device 5 capable of power saving in the event time zone.

In step S106, the fifth calculation unit 2384 calculates the total estimated reduction power amount in the event time zone.

In step S107, the sixth calculator 2385 calculates the total reduction amount in the event time zone.

In step S108, the display instruction unit 239 determines the content of the DR notification, the device list data generated by the device list generation unit 237, and the respective calculation results of the first calculation unit 2380 to the sixth calculation unit 2385. Generate event information.

In step S109, the display instruction unit 239 instructs the operation terminal 3 to display the generated event information. Specifically, the display instruction unit 239 generates a command for instructing display of the generated event information, and transmits the generated command to the operation terminal 3 via the user interface processing unit 230.

As described above, the event information screen as shown in FIG. 6 is displayed on the operation terminal 3. Note that the display instruction unit 239 instructs the operation terminal 3 to close the event information screen when the control mode is switched from the DR mode to the normal mode. In addition, even after the event information screen is displayed, if there is a change in the display content (for example, the estimated total power consumption or the electricity bill), the display instruction unit 239 will change the operation terminal 3 after the change. Instructs display of event information. Thereby, the event information screen of the operation terminal 3 is appropriately updated to the latest contents.

FIG. 9 is a flowchart showing a procedure of event control processing executed by the control unit 23 of the control device 2. This event control process is started after the end of the event information display process described above.

In step S201, the user interface processing unit 230 determines whether the control execution button on the event information screen displayed on the operation terminal 3 has been pressed by the user. When the control execution button is pressed by the user (step S201; YES), the user interface processing unit 230 notifies the control pattern acquisition unit 240 accordingly.

In step S202, the control pattern acquisition unit 240 acquires the content of the control pattern selected by the user via the user interface processing unit 230.

In step S203, the device control unit 241 controls the target device 5 based on the acquired control pattern. Specifically, when the scheduled usage time included in the acquired control pattern is reached, the device control unit 241 generates a control command indicating the control content included in the control pattern, and the generated control command is transmitted to the wireless communication unit 21. Is transmitted to the target device 5 via. The device 5 that has received such a control command performs an operation according to the received control command.

As described above, in the device control system 1 according to the first embodiment of the present invention, upon receiving the DR notification, the list of the devices 5 that can perform power saving control in the event time zone specified by the DR notification, and the power saving control An event information screen including the estimated power reduction amount for each device 5 that can be displayed is displayed on the operation terminal 3 and presented to the user. For this reason, the user can easily grasp the device 5 that can save power, can recognize the effect of the power saving control in more detail, and can easily take appropriate measures.

In addition, the estimated total power consumption, the electricity charge corresponding to the estimated total power consumption, and the reduction of the electricity charge corresponding to the estimated reduced power consumption for each device 5 are also displayed, so that the user understands the power saving effect. Becomes easier.

Furthermore, since the user can select a desired control pattern and execute control via the event information screen displayed on the operation terminal 3, power saving control according to the user's preference is possible.

The content of the event information displayed on the operation terminal 3 is not limited. For example, as shown in FIG. 10, the event information may include an input field for accepting an input of a target reduction amount of power consumption or a target reduction amount of electricity charges from a user, and an automatic selection button. In this case, when the target reduction amount or the target reduction amount is input by the user and the automatic selection button is pressed, the device control unit 241 performs 1 or 2 for achieving the input target reduction amount or the target reduction amount. A plurality of control patterns are selected, and the selection results are displayed on the operation terminal 3. Thereby, in the event display screen, the check box corresponding to the control pattern selected by the device control unit 241 is in a state in which a check is entered. Thus, the convenience of the user is further improved by providing the control pattern automatic selection function.

Further, the event information may include an estimated power consumption amount and an electricity charge at the time of non-power saving control of the device 5 capable of power saving control.

In addition, when generating the device list data, the device list generation unit 237 may sort the arrangement of the records in descending order of the estimated power reduction amount.

Further, after the end of the event time period, the display instruction unit 239 may instruct the operation terminal 3 to display the actual information including the actual value of the power consumption and the fixed amount of the electricity charge in the event time period.

When displaying the result information as described above, the calculation unit 238 of the control unit 23 may further include a seventh calculation unit (not shown). When the power saving control for any device 5 capable of power saving control is actually performed in the event time zone, the seventh calculating unit performs the non-power saving control for all the devices 5 capable of power saving control. A first estimated power consumption amount is calculated, and a first estimated power reduction amount is calculated by subtracting the actual value from the calculated first estimated power consumption amount.

In addition, the seventh calculation unit calculates a first electricity charge corresponding to the first estimated power consumption and a first reduction amount corresponding to the first estimated power consumption. And the display instruction | indication part 239 included the actual value of power consumption, the fixed amount of electricity bill, 1st estimated power consumption, 1st electricity bill, 1st estimated reduction power amount, and 1st reduction amount The operation terminal 3 is instructed to display the result information. An example of the record information screen displayed on the operation terminal 3 in this case is shown in FIG.

Further, the calculation unit 238 of the control unit 23 may further include an eighth calculation unit (not shown). The eighth calculation unit performs the power saving control when all the devices 5 capable of power saving control are performed when the non power saving control is actually performed for all the devices 5 capable of power saving control during the event time period. (2) While calculating the estimated power consumption, a second reduction power amount is calculated by subtracting the second estimated power consumption amount from the actual value.

In addition, the eighth calculation unit calculates a second electricity rate corresponding to the second estimated power consumption amount and a second reduction amount corresponding to the second estimated reduction power amount.
