Description

  The present invention relates to a power control system that detects and controls power consumed by an electrical device when the electrical device is used, prevents a breaker from being cut off due to excessive use of electricity, and promotes energy saving of power consumption in the home. Is.

  An example of a conventional power control system is shown in FIG. The conventional power control system is configured by an adapter 76 having an adapter outlet 75 connected to an outlet 72 distributed from the distribution board 71 and connected to a commercial power source 70 and connected to a plug 74 of an electric device 73 and a controller 77. doing. The adapter 76 includes an adapter plug 78, a line connected to the adapter plug 78, a relay 79 provided on the line, a power detection unit 80 that detects power consumed by the electric device 73, and the relay 79. An energization control unit 81 that drives the power supply, an adapter control unit 82 that controls the energization control unit 81, a communication unit 83 that communicates with the controller 77, an adapter outlet 75 that is the end of the line, An adapter-side device control information transmission / reception means 84 is provided for obtaining the operation status of the electric device 73 from the electric device 73 and instructing the electric device 73 of the operation stage.

  The electrical equipment 73 is a refrigerator, dishwasher / dryer, washing / drying machine, microwave oven, rice cooker, etc. In this system, the equipment side equipment control information transmission / reception means 85 communicates with the adapter side equipment control information transmission / reception means 84 of the adapter 76. This is an electric device having a so-called network function. Reference numeral 86 denotes device control means constituted by a microcomputer.

  Further, the controller 77 detects the power consumed by all the electrical devices connected to the communication means 87 that communicates with the communication means 83 of the adapter 76, the controller control means 88, and the main breaker of the distribution board 71. Means 90 and 91 are provided. For the communication means 83 of the adapter and the communication means 87 of the controller, a power line carrier communication means, an infrared communication means, a weak wireless communication means, and a specific low power wireless communication means are used.

  Reference numerals 92 and 93 denote house code setting units. This is a setting unit for assigning a unique code to each house so that it does not communicate with the controller or adapter of the neighbor's system when the neighbor uses the same system. A dip switch is used.

  Reference numeral 94 denotes an adapter identification code setting unit, which is an identification code setting unit for the controller 77 to set an identification code for identifying the adapter, and is assigned so that no adapter having the same identification code exists in one house. To go. This also uses a dip switch of about 8 to 16 bits.

  Reference numeral 95 denotes an identification code setting unit of the controller 77. Usually, since only one controller is used in one system, the identification code setting unit 95 of the controller 77 may be omitted.

  The identification code setting unit 94 may also serve as a priority between adapters when power is suppressed. For example, when power is insufficient, prioritization such as suppressing power in order from the smallest identification code is automatically performed.

A microcomputer is used for the adapter control means 82 and the controller control means 88. When the adapter control means 82 receives a control signal for suppressing power consumption of the electrical equipment from the communication means 83, the adapter control means 82 outputs a signal to the energization control section 81 to operate the relay 79 and turn off the energization.

  Here, if the electrical device is used too much and the breaker rating is approached, or if the electrical device is used excessively and the breaker rating is exceeded, a power consumption suppression signal is output from the controller 77 to the adapter 76. The adapter 76 operates to turn off the electrical device 73 by operating the internal relay 79.

  Since the device control means 86 of the electric device 73 is controlled by the microcomputer, when the power is turned off by the adapter 76, the operation of the microcomputer in the device control means 85 of the electric device 73 is performed when the power is restored. The information stored in the RAM that stores the operation state of the electric device before the power is turned off is lost, and the operation state before the energization control cannot be restored.

  Therefore, conventionally, when the controller 77 instructs the adapter 76 to reduce power consumption, the device control unit 86 of the electric device 73 is first passed through the device side device control information transmission / reception unit 85 and the adapter side device control information transmission / reception unit 84 to the adapter 76. The microcomputer is instructed to acquire information in the RAM necessary for return from the microcomputer.

  Based on this instruction, the device control means 86 transmits information in the RAM necessary for returning to the adapter 76 such as the operating state of the electric device stored at a predetermined address in the RAM. The information in the RAM is sent to the controller 77 by the adapter 76 and stored in the controller 77. The controller 77 transmits the in-RAM information to the adapter 76 together with an instruction to return power when the power consumption suppression is finished. The adapter 76 resumes energization of the electrical device 73 by the relay 79 and operates the device control means 86, and then transmits the information in the RAM through the device side device control information transmission / reception means 85 and the adapter side device control information transmission / reception means 84. Then, the state before power consumption suppression is restored.

  Thus, conventionally, by returning the information in the RAM necessary for resuming the operation of the device control unit 86 immediately before the start of power consumption suppression by the controller 77 to the device control unit 86 when power is restored, the power is turned off by the power consumption suppression instruction. The lost RAM information of the microcomputer of the electric device 73 is restored so that the operation of the electric device 73 can be continued from the original state (see, for example, Patent Document 1).

  However, in the conventional configuration, when the power is excessively used, a power consumption suppression request is issued from the controller to the adapter, and the adapter only operates the internal relay to cut off the power to the electrical device. Yes, there is no notification regarding the electrical equipment that consumes a large amount of power that has caused the situation of power consumption suppression, so the user of the electrical equipment that consumes a large amount of power uses the electrical equipment. I was unaware that other electrical devices had reduced power consumption. For this reason, users of electrical equipment consuming large amounts of power can save power by using the electrical equipment in as short a time as possible, and do not bother other users of electrical equipment. I didn't know it would be over.

In view of the above-described conventional problems, the present invention, for example, during cooking while heating with a stove in a kitchen, a person in the living room raised the heating temperature of the air conditioner in the living room, so that the power consumption of the entire house exceeded a predetermined value. If the controller issues a power consumption control request to the stove adapter, and the stove adapter turns off the power to the stove, it is confirmed that other devices have been controlled for power consumption by the living room air conditioner adapter. The purpose is to provide a system that can notify a person in the living room, and can recognize that the power of the air conditioner is excessively used by the person in the living room, and can be conscious of saving energy.

  In order to solve the conventional problems, a power control system according to the present invention includes a controller that measures main power of a distribution board and an adapter that measures power consumption of an electric device, and the controller uses power consumption in a home. A first notification indicating that the power consumption of the electrical device has been increased before the first adapter having a low priority is requested to suppress power consumption when the power becomes larger than a predetermined value. The second adapter that has performed the second notification indicating that the power consumption of the other electrical device is suppressed, and the second adapter drives the notification means to consume the other electrical device. The power control system notifies the user that power has been suppressed.

  As a result, it is possible to provide a system that allows a user who has started using too much power to recognize that the user is using too much power and is conscious of trying to save energy.

  In the power control system of the present invention, another electrical device consumes the second adapter that has made the first notification indicating that the power consumption of the electrical device has increased before the power consumption control request is issued. By giving the second notification indicating that power has been suppressed, it is possible to make the user who has started using too much power recognize that the power is being used excessively and to have an awareness of energy saving.

A second notification indicating that power consumption of another electrical device has been suppressed is sent to the second adapter that has sent the first notification indicating that the second adapter has driven the notification means. Thus, it is possible to notify the user that the power consumption of other electrical devices has been suppressed.

  In the fourth aspect of the invention, it is an adapter for an electric device with a large power consumption that informs the user that the power consumption of another electric device has been suppressed. On the other hand, it can be notified that the power consumption of other electrical devices has been suppressed.

  According to the fifth aspect of the present invention, the power consumption of other electrical devices is suppressed for the user of the electrical device with large power consumption by periodically driving the notification means while the power consumption of the electrical device is suppressed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the present embodiment.

(Embodiment)
FIG. 1 shows a configuration diagram of a power control system according to a first embodiment of the present invention.

  1, in the embodiment of the present invention, the power lines L1 and L2 on the outlet side of the distribution board 1 into which a single-phase three-wire system 200V is drawn into the home are sandwiched between clamper-type current sensors 2, and the controller 3 To measure the power consumed in the home. To accurately measure the power consumed in the home, measure the voltage and calculate the power factor by looking at the voltage phase and current phase, or measure the voltage and current every 100 ms, for example. The power value must be calculated by adding the result of multiplying the voltage value and the current value for one AC cycle, but only the current measurement is possible because the power consumption in the home can be observed from the current value alone. In this method, the power is estimated.

  Since the controller 3 is usually attached to the upper part of the wall next to the distribution board 1 in the same manner as the distribution board, it is installed in the entrance, the entrance, the storage, the washroom, the toilet, and the like.

  The output line of the distribution board 1 is connected to an AC 200V system as an IH cooking heater 4, as an AC 100V system, as an L1 phase, a dryer 36, an adapter 5A to which a stove 7 is connected, and a living room air conditioner 8 as an L2 phase. The adapter 5B and the television 10 are connected.

  Further, the controller 3, the adapters 5A, 5B, and the status notification device 9 have communication means (not shown) that communicates by radio waves as a first communication medium, and can transmit information to each other.

  In particular, when the total power consumption becomes excessive, the controller 3 sends a power consumption suppression request for restricting energization to the adapter 5A or adapter 5B, and puts the electric device connected to the adapter into a power consumption suppression state. After that, when the total power consumption is reduced and there is a margin, the adapter 5A or the adapter 5B is sent a power consumption suppression release for returning the power to the normal state, and the electric device connected to the adapter is brought into a normal state.

  As a radio wave communication method, a specific low-power radio using a 400 MHz band frequency is used. Reference numeral 6 denotes a wireless antenna of communication means for communicating with the first communication medium.

  The status notification device 9 can intercept wireless communication data transmitted in a space within the same system and collect information on each electrical device, and is equipped with a WEB server as software, such as text and images It is a unit that can be constructed at low cost because it does not have display means that can display.

  Furthermore, the status notification device 9 and the television 10 are internally provided with second communication means (not shown) for communicating with each other via a general-purpose LAN cable 11 which is a second communication medium. The TV 10 is provided with a WEB browser, and is displayed on the screen using a WEB browser of an electric device having a WEB client function such as the TV 10 or a personal computer (not shown) via a general-purpose LAN cable. Information collected by the status notification device 9 can be browsed.

  In other words, the status notification device 9 and the television 10 or the status notification device 9 and a personal computer (not shown) serve as remote confirmation setting means 50, and perform various settings of the controller 3, the adapter 5A, or the adapter 5B, and check the operation status of each. It becomes an interface means with the user for doing.

  In addition, the number of televisions and personal computers that communicate with the status notification device 9 via the second communication medium LAN is not limited to one, and televisions and personal computers placed in various rooms communicate with the status notification device 9. Can interface with family members.

  Note that the general-purpose LAN is not specifically designated physically, and may be anything as long as it is a network network capable of transmission / reception using the HTTP protocol, and need not be wired.

  Reference numeral 12 denotes a hub for branching and distributing LAN cables. The television 10 can be connected to the Internet 14 via a modem / router 13.

  In an actual home, many other electrical devices are connected. However, in order to simplify the description, the following description will be given as the above configuration.

  FIG. 2 is a block diagram of the controller 3 of the power control system. The controller 3 applies a signal from a clamper type current sensor (2A in FIG. 1) attached to the L1 phase of the single-phase three-wire system 200V to the power system line. Similarly, the L1 current detector 15A that measures the flowing current and the current that flows to the power system line from the signal of the clamper type current sensor (2B in FIG. 1) attached to the L2 phase of the single-phase three-wire system 200V are measured. There is an L2 current detection unit 15B, and the power value is calculated by the power calculation means 16 based on the current values measured by the L1 current detection unit 15A and the L2 current detection unit 15B.

Reference numeral 17 denotes a communication means for communicating with a radio wave as a first communication medium. Control unit 18A
Performs arithmetic processing on the measured power data, analyzes a message received by the communication means 17, and generates a transmission message for transmitting a control signal and data.

  The upper limit storage unit 19 stores the current value flowing in the L1 phase and the L2 phase and the upper limit value of power calculated based on this current value. The setting of the upper limit value may be described in advance in the microcomputer program of the control unit as a default value.

  Reference numeral 20 denotes an electric device power consumption storage unit, which stores the power consumption of the electric device connected to each adapter sent from the adapters 5A, 5B, etc. through the communication means 17 at intervals of 1 minute together with the reception time. is there.

  Reference numeral 21 denotes a clock function unit which keeps time, and when the control unit 18A stores the power consumption value of each electrical device sent from the adapters 5A, 5B, etc. in the electrical device power consumption storage unit 20, this clock function. The time is read from the unit 21 and stored together with the power value. Alternatively, the clock function unit 21 may be a counter configured to start or stop counting in seconds or to be initialized under the control of the control unit 18A, and to allow the control unit 18A to freely read the count value.

  Although the same thing as the house code setting part 93 and the identification code setting part 95 shown in FIG. 8 of a prior art example may be required also for the controller 3 of this Example, illustration is abbreviate | omitted.

  FIG. 3 is a block diagram of an adapter 5A connected to an electric device such as an electric heater 7 of the power control system. The adapter 5A is provided with a power plug 23 and an outlet 24. The power plug 23 is inserted into a household outlet, and the power detection means 25 of the electric stove 7 is inserted into the outlet 24.

  When the control unit 18B receives the power consumption control request from the controller 3, the control unit 18B outputs a signal to the energization control unit 27, opens the relay 22 and cuts off the energization to the electric device such as the electric stove 7, and conversely, it has a margin in power. When the power consumption suppression cancellation is received from the controller 3, a signal is sent to the energization control unit 27 to close the relay 22, and energization to the electric device such as the electric stove 7 is resumed.

  The power detection means 25 always detects the power consumption of the electric equipment connected to the adapter 5 </ b> A such as the electric heater 7 by the control unit 18 </ b> B. The power detection means 25 measures the voltage of the commercial power source supplied to the electric device such as the electric heater 7 and the current flowing through the electric device such as the electric heater 7 at intervals of 100 milliseconds, and the voltage value and the current value. The power value is calculated by adding the result of multiplying by one AC cycle. Of course, a method of estimating the power only from the current value may be used.

  28 is a device operation determination means for determining the operation state and the stop state of the electric device connected to the adapter. Whether the electric device such as the electric stove 7 is in the OFF state or the standby / stop state by the output of the power detection means 25, Judge whether it is operating / running state.

Reference numerals 29 and 30 are notification means, which are constituted by light-emitting diodes in this embodiment. Reference numeral 29 indicates that the connected electrical device (stove 7 in FIG. 3) is turned off by a power consumption suppression request from the controller 3. This is a notification during power suppression that is turned on when the power is on, and the green light is continuously turned on. If the controller detects excessive use of power immediately after the user starts using the electric stove 7, the controller 3 requests the adapter (not shown) of another low-priority electrical device to suppress power consumption. At the same time, the controller 3 notifies the adapter of the electric heater 7 that the power consumption of other electric devices has been suppressed by using the electric heater 7. 30 is a notification means that lights up in response to a notification from the controller 3 that the power consumption of other electrical devices has been reduced by using the electric stove 7, and blinks red.

  Although the same thing as the house code setting part 92 and the identification code setting part 94 shown in FIG. 8 of a prior art example may be required also for the adapter 5A of this Example, illustration is abbreviate | omitted.

  FIG. 4 is a block diagram of an adapter 5B connected to an electric device such as an air conditioner 8 of the power control system. This adapter 5B is connected to an electric device of a type that can control operation start / stop, setting value, operation mode change, and the like from an infrared remote controller. On the other hand, the adapter 5A described above has no remote controller such as a toaster, a jar pot, or a stove, and is connected to an electric device of a type in which the user directly turns on and off the switch.

  In FIG. 4, a remote control transmission unit 31 transmits a remote control signal from an infrared light emitting diode, and transmits a control signal such as an operation mode such as cooling or heating of the air conditioner 8, temperature, air volume, etc. as a remote control signal.

  The remote control receiving unit 32 receives a remote control signal, intercepts the remote control signal transmitted by operating the remote control attached to the air conditioner 8, and stores the remote control signal data. When canceling the power consumption suppression state, the stored remote control signal data is transmitted from the remote control transmission unit 31 to the air conditioner 8 as a remote control signal.

  The power consumption of the air conditioner 8 connected to the adapter 5B is always detected by the control unit 18C by the power detection means 25 in the same manner as the adapter 5A. Further, the device operation determination means 28 also determines whether the connected air conditioner 8 is in operation or in a stopped state in the same manner as the adapter 5A.

  Further, since the adapter 5B includes the remote control receiving unit 32, the operation of the air conditioner 8 can also be grasped by receiving the infrared remote control signal operated by the user with the remote control of the air conditioner by the remote control receiving unit 32.

  The control unit 18C outputs a remote control signal for suppressing power consumption from the remote control transmission unit 31 to the air conditioner 8 when the power consumption suppression request or information on usable power is received from the controller 3 and power consumption suppression is necessary. . Specifically, for example, the operation mode is changed from “heating” to “fan”. As an advantage of “air blowing”, the compressor of the air conditioner 8 is stopped, so that the power consumption of the air conditioner 8 can be reduced to about several tens of watts. Since it is understood that the air conditioner 8 has been stopped, it is possible to prevent the user from forgetting to attach the air conditioner 8.

  Similarly to the adapter 5A, the adapter 5B is provided with a power plug 23 and an outlet 24. The power plug 23 is plugged into a household outlet, and the power detection means 25 of the air conditioner 8 is plugged into the outlet 24. Thus, the power detection means 25 can grasp the power consumption of the air conditioner 8.

  Further, if the air conditioner 8 itself includes a communication means for communicating with other electrical devices via the first communication medium and a power calculation means for measuring the power consumption of the self, the air conditioner has a communication function and the adapter 5B is unnecessary. It becomes.

  The notification means 29 and the notification means 30 of the adapter 5B in FIG. 4 are also configured by light emitting diodes in the present embodiment, similarly to the adapter 5A, and the connected air conditioner 8 is energized in response to a power consumption suppression request from the controller 3. This is a notification during power suppression that is turned on when the power is turned off.

  If the controller detects excessive use of power immediately after the user changes the heating temperature of the air conditioner 8 to a higher value, the controller 3 can be replaced with another low priority electrical device adapter (for example, the adapter 5A of the electric stove 7). At the same time, the controller 3 notifies the adapter 5B of the air conditioner 8 that the power consumption of other electrical devices has been suppressed by changing the set temperature of the air conditioner 8. Reference numeral 30 is a notification means that lights up in response to a notification from the controller 3 that the power consumption of the other electrical device has been suppressed by changing the set temperature of the air conditioner 8, and blinks red.

  Further, if the IH cooking heater 4 has built-in communication means for communicating with other electrical equipment via the first communication medium and power calculation means for measuring the power consumption of itself, the IH cooking heater with communication function (electric equipment) It becomes possible to exchange information with the controller 3 and other electrical devices, and when power is insufficient during water heating, it is also possible to automatically turn off the water heating power and pass the power to other devices. become.

  Although the same thing as the house code setting part 92 and the identification code setting part 94 shown in FIG. 8 of a prior art example may be required also for the adapter 5B of this Example, illustration is abbreviate | omitted.

  FIG. 5 is a block diagram of the status notification device 9. Reference numeral 33 denotes a control unit of the status notification device 9, which basically has a function equivalent to that of a personal computer. The first communication means 17 exchanges information with the controller 3, the adapter 5A, or the adapter 5B.

  Reference numeral 34 denotes a second communication means for communicating with each other via a general-purpose LAN cable 11 as a second communication medium. Reference numeral 35 denotes a WEB server function unit having WEB server information for display on the screen of a partner terminal (such as a personal computer or a WEB-compatible television).

  Although the same thing as the house code setting part 93 and the identification code setting part 95 shown in FIG. 8 of a prior art example may be required also for the status notification apparatus 9 of this Example, illustration is abbreviate | omitted.

  The electrical device power consumption storage unit 20 is the same as that used for the controller 3, and the consumption of electrical devices connected to each adapter sent from the adapters 5A, 5B, etc. through the communication means 17 at intervals of 1 minute, for example. The power is stored together with the reception time, the clock function unit 21 is the same as that used for the controller 3, and the power consumption value of each electrical device sent from the adapter 5A, 5B, etc. by the control unit 33 Is stored in the electric power consumption storage unit 20 and the time is read from the clock function unit 21 and stored together with the power value.

  The operation of the controller 33 storing the power consumption value of each electrical device sent from the adapters 5A, 5B, etc. in the electrical device power consumption storage unit 20 is performed by either the controller 3 or the status notification device 9. Therefore, if the controller 3 has the electric device power consumption storage unit 20 and the clock function unit 21, it is not necessary for the status notification device 9. Conversely, the status notification device 9 has the electric device power consumption storage unit 20 and the clock function. If the unit 21 is provided, the controller 3 does not require the electric device power consumption storage unit 20 and the clock function unit 21.

  Next, the operation will be described with reference to an explanatory diagram of a screen displayed on the television by the status notification device 9 in FIG. 6 and a flowchart in FIG. 1 is installed in the living room, and the electric stove 7 is installed in the kitchen. One of the family members in this house uses the dryer 36 in the bathroom, and the air conditioner 8 in the living room is in a heating operation. Usually, the status notification device 9 transmits data from the second communication means to the living room TV 10 having the WEB client function as the power consumption of the entire house as shown in FIG. The graph screen showing the time change from the morning is displayed.

  For example, it is assumed that the housewife of this house is cooking in the kitchen and is using the electric stove 7, and that another housekeeper is heating the air conditioner 8 in the living room. Here, when another family member in the living room changes the set temperature of the air conditioner 8 to a higher temperature, the adapter 5B has increased the power consumption of the air conditioner 8 due to the output of the power detection means 25 or the device operation determination means 28. (Step S101 in FIG. 7) and notifies the controller 3 that the power consumption has increased (step S102).

  In step S101, it is determined whether or not the power consumption of the air conditioner has increased. In step S102, it is notified that the power consumption of the air conditioner has increased. In step S101, the user changes the set temperature using the remote control receiver 32. In step S102, the controller 3 may be notified that the set temperature of the air conditioner has been changed.

  When the controller 3 receives a notification from the adapter 5B that the power consumption of the air conditioner 8 has increased, the controller 3 reads the time (TIME_A) of the clock function unit 21 of the controller 3 and together with the time of reading to the electric appliance power consumption storage unit 20, The power consumption value is stored (step S103). Further, the controller 3 constantly monitors the total power consumption of this house and determines whether or not the total power consumption exceeds 5 kW (step S104), but the power consumption of this entire house is an allowable amount (for example, 5 kW). ).

  At this time, in order to prevent the breaker of the distribution board from being cut off, the controller 3 tries to suppress the power consumption in order from the lowest power usage priority among the devices capable of controlling the power consumption suppression from the controller 3. Normally, the priority of stoves and air conditioners is lowered, and cooking-related electric equipment that may interfere with the completion is raised. Furthermore, it is assumed that the electric stove 7 has a lower priority than the air conditioner 8.

  Then, the controller 3 determines whether or not the electric stove 7 is used (step S105). If the electric stove 7 is not used, a request for suppressing the power consumption is made to the adapter 5B of the air conditioner 8 in order to reduce the power consumption of the air conditioner 8. (Step S106). The adapter 5B changes the operation mode from “heating” to “fan” in order to suppress the power consumption of the air conditioner 8. The operation mode is changed by transmitting a remote control signal to the air conditioner 8 using the remote control transmission unit 31 of the adapter 5B (step S107).

  If the electric stove 7 is used, a power consumption suppression request for suppressing the power consumption of the electric stove 7 is issued to the adapter 5A of the electric stove 7 in order to turn off the electric stove 7 (step S108). In response to the power consumption suppression request from the controller 3, the adapter 5A opens the relay 22 of the adapter 5A and turns off the electric heater 7 (step S109).

  Further, the controller 3 reads the time (TIME_B) of the clock function unit 21 of the controller 3 (step S110), calculates the difference between the time (TIME_A) and the time (TIME_B) previously stored in the electric appliance power consumption storage unit 20, Based on the value of the time difference between the time (TIME_A) and the time (TIME_B), it is checked whether the total power consumption is greater than the value stored in the upper limit storage unit 19 immediately after the power consumption of the air conditioner 8 increases (step S111). ).

  For example, if the difference between the time (TIME_A) and the time (TIME_B) is within 5 minutes, it will be immediately after that the living house person has increased the set temperature of the air conditioner 8, which increases the power consumption of the air conditioner 8, and therefore overuses the power. Therefore, it is determined that the total power consumption has exceeded 5 KW, and the controller 3 notifies the adapter 5B of the air conditioner 8 that the power consumption of other electrical devices has been suppressed by using the air conditioner 8 (step S112).

When the adapter 5B of the air conditioner 8 receives a notification from the controller 3 that the power consumption of other electrical devices has been reduced, the reporting means 30 of the adapter 5B blinks red (step S113).

  If the difference between the time (TIME_A) and the time (TIME_B) exceeds 5 minutes in step S111, the total power consumption is greater than the value in the upper limit storage unit 19 immediately after the power consumption of the air conditioner 8 increases. Judge that there was no.

  The status notification device 9 also intercepts a power consumption suppression request signal from the controller 3 to the adapter 5A, and an image to be displayed on the television 10 by detecting this power consumption suppression request signal is as shown in FIG. The user is notified that the switching electric stove 7 is temporarily stopped (message frame 42 in FIG. 6B).

  In this way, the adapter that has been notified that the power consumption of the electrical device has increased before the power consumption control request is issued notifies the adapter that the power consumption of the other electrical device has been suppressed. It is possible to make the user who has started too much recognize that the power is being used excessively, and to have energy saving awareness.

  In this embodiment, the controller 3 compares the time when the power consumption of the air conditioner 8 is increased (or the time when the set temperature is changed by the user) with the time when the total power consumption exceeds 5 KW, and the difference within 5 minutes. If this is the case, the adapter 5B of the air conditioner 8 has been informed that the power consumption of the stove has been reduced, but the adapter 5B of the air conditioner 8 has increased the power consumption of the air conditioner 8 (or the set temperature has changed by the user). And the controller 3 intercepts that the electric heater 7 has requested to reduce power consumption, finds the time difference, and if the difference is within 5 minutes, the adapter 5B of the air conditioner 8 voluntarily reports. 30 may blink in red.

  Further, the status notification device 9 of the remote confirmation setting means 50 intercepts the communication between the controller 3 and the adapters 5A and 5B, and the status notification device 9 is the time when the power consumption of the air conditioner 8 is increased (or the set temperature is determined by the user). The time when the total power consumption exceeds 5 kW is compared, and if the difference is within 5 minutes, it indicates that the power consumption has been suppressed on the stove from the status notification device 9 to the adapter 5B of the air conditioner 8. May be notified. In this case, similar to the controller 3, the situation notification device 9 can be easily realized by providing the electric appliance power consumption storage unit 20.

  In this embodiment, the time when the power consumption of the air conditioner 8 is increased (or the time when the set temperature is changed by the user) is compared with the time when the total power consumption exceeds 5 kW, and whether or not the difference is within 5 minutes. By taking the method of checking the power consumption, it was notified to other electrical devices that the power consumption increased in the nearest time before the total power consumption exceeded 5KW. You may make it notify to the adapter of the electric equipment which is consuming the electric power.

  In this way, it is possible to make the user of the electric device that consumes the most power recognize that the power is excessively used and to have energy saving awareness.

  In addition, when the power consumption of the electrical device is suppressed, the notification means is periodically driven, so that the user who uses excessive power can be more effectively energy-saving.

If the air conditioner 8 itself includes communication means for communicating with other electrical devices via the first communication medium, power calculating means for measuring its own power consumption, reporting means 29 and reporting means 30, the adapter 5B. Is not required, and when the set temperature of the heating operation is changed to a low temperature in response to a request for suppressing power consumption from the controller 3, the notification means 29 is turned on as a notification that the power consumption is being suppressed. In the case where the notification that the power consumption of the electrical device is suppressed is made, the notification means 30 can be blinked without an adapter.

  Similarly, the IH cooking heater 4 itself incorporates communication means for communicating with other electrical devices via the first communication medium, power calculation means for measuring its own power consumption, reporting means 29 and reporting means 30. For example, the controller 3 and other devices can be linked. For example, when a power consumption suppression request is received from the controller 3, the power of the IH burner is lowered, and the notification means 29 is turned on as a notification that power is being suppressed. When the controller 3 receives a notification that the power consumption of other electrical devices has been suppressed by using IH, the reporting means 30 can be blinked.

  In addition, when viewing the usage status of power in the house on the television 10 as in the present embodiment, the WEB browser needs to be activated on the television 10. In order to view the message screen from the status notification device 9 on the television 10, the IP address on the second communication medium of the status notification device 9 is set in the status notification device 9 in advance, and is further set in the WEB browser of the television 10. In addition, it is necessary to register the IP address of the status notification device 9. The IP address on the second communication medium of the status notification device 9 stores a value such as “192.168.1.80” as a default value at the time of shipment from the factory. If the IP address is the same as that of an electric device connected to another LAN, the IP address can be changed by a procedure described later.

  If a liquid crystal display element is attached to the housing of the controller or adapter, the power consumption of the electrical device has been reduced, and the operation time information of the electrical device in that case is displayed on the controller or adapter to notify the user. You can also.

  In the present embodiment, data transmission / reception is performed by specific low-power wireless communication that does not require wiring as the first communication medium. However, power line communication or wired connection may be used.

  In addition, all of this embodiment can be configured in the same manner as a program for causing a computer to function as all or part of the means of the power control system.

  Note that the means / units described in this embodiment include hardware resources such as a CPU (or microcomputer), a RAM, a ROM, a storage / recording device, an electrical / information electrical device including an I / O, a computer, a server, and the like. You may implement in the form of the program made to cooperate. In the form of a program, new functions can be easily distributed / updated and installed by recording them on a recording medium such as magnetic media or optical media or distributing them via a communication line such as the Internet.

  As described above, the power control system according to the present invention detects and controls the power consumed by the electric device when the electric device is used, prevents the breaker from being cut off due to excessive use of electricity, and saves power. It can be used for promoting systems.
