This electric device is connected to the net remote controller 3 and the net remote controller 4.

  For example, an electrical device 9 such as a lighting device or an air conditioner installed in a living room in a house is connected to the net remote controller 3, and an electrical device 9 such as an IH heater installed in a kitchen is connected to the net remote controller 4. Is done. The network remote controller 3 and the network remote controller 4 are not configured to be connected to various electrical devices 9 for each room in the house, but to the electrical remote controller 9 such as a network remote controller to which only an air conditioner or only a lighting device is connected. It may be according to the type.

  A wireless security system 10 is connected to the net remote controller 4. The wireless security system 10 receives sensors such as human sensors, door opening / closing sensors, window opening / closing sensors, smoke sensors, abnormality notification buttons, sensor signals detected by the sensors and operation signals of abnormality notification buttons. It is configured by an electric device 9 such as a notification device that performs notification when a sensor signal or an operation signal received by the receiver or the wireless receiver is abnormal. When the wireless security network adapter 5 receives a sensor signal or operation signal detected by the wireless security system 10 from a wireless receiver, the wireless security network adapter 5 outputs the sensor signal or operation signal to the outside via the information breaker 1.

When the center server 12 receives a command for controlling the home electrical device 9 from the mobile terminal 20, the center server 12 transfers the command to the information breaker 1 corresponding to the IP address of the mobile terminal 20, and the electrical device 9 To work.

  The energy management unit 2 in the power management system configured as described above is installed in a detached house or an apartment house. As shown in FIG. 3, commercial power is supplied to the in-house distribution board, and the commercial power is connected to the main breaker 40 and the branch breaker 41. The branch breaker 41 is divided into, for example, a 200V dedicated circuit, a 100V dedicated circuit, and an outlet lighting circuit. Further, the branch breaker 41 is connected to different electrical devices 9 in the section.

  The electric power supplied by the commercial power supply is first supplied to the main breaker 40 and then supplied to each electric device 9 by being supplied to a plurality of branch breakers 41 provided in each of the branch electric circuits. Therefore, a current for operating all the electric devices 9 operating in the house flows through the main breaker 40, and a current for operating each electric device 9 flows through each branch breaker 41.

  In the power management system shown in FIG. 1, the branch breaker 41 may be provided for each electrical device 9 installed in the house, may be provided for each room in the house, It may be provided for each type of device 9. A branch breaker current detector 34 described later is provided for each branch breaker 41. When the branch breaker 41 is provided for each room, it detects the amount of power used by the electrical equipment 9 provided for each room. However, when the branch breaker 41 is provided for each type of the electric device 9, the power usage amount of the electric device 9 for each type of the electric device 9 is detected.

  As shown in FIG. 2, the energy management unit 2 is connected to a main breaker 40 that is connected to a commercial power source and supplies power to a plurality of electrical devices 9 in the home to a calculation unit 31 that is configured by a microcomputer or the like. A current detection unit 32, a power calculation unit 33, a branch breaker current detection unit 34 to which a branch breaker 41 is connected, a primary branch breaker 35, a control unit 36, and a database storage unit 37 are connected.

  The energy management unit 2 includes a main current detection unit 32, a power calculation unit 33, and a branch breaker current detection unit 34 as a power measurement interface. The energy management unit 2 detects the current value flowing through the main breaker 40 by the main current detection unit 32, calculates the total power usage amount in the home via the main breaker 40 by the power calculation unit 33, and calculates To the unit 31. In addition, the energy management unit 2 detects the current value supplied from the branch breaker 41 to the electrical device 9 by the branch breaker current detection unit 34 and supplies it to the calculation unit 31. Such a trunk current detection unit 32 functions as a measurement unit that measures the amount of power used to be supplied to the electrical device 9 via the trunk breaker 40.

  The calculation unit 31 functions as an overcurrent determination unit that determines an overcurrent based on the predetermined threshold value of the main breaker 40 and the power usage amount of the main breaker 40 measured by the main current detection unit 32. The calculation unit 31 limits the power usage of each electric device 9 based on a database including a controllable order that allows control for suppressing power consumption of the electric device 9 when there is an overcurrent (determination). Control means). The control of each electrical device 9 is realized by causing the calculation unit 31 to output a control signal from the control unit 36 to the electrical device 9.

  The suppression control of the power consumption of the electric device 9 includes a control for stopping the electric device 9 and a control for reducing the power consumption of the electric device 9. That is, starting and stopping the electrical device 9 is included in the stop control of the suppression control. Changing the electrical device 9 from the normal mode to the energy saving mode is included in the reduction control in the suppression control, and changing the operation from the temperature setting of the air conditioner or the like to the strong → weak driving amount is also the reduction control in the suppression control. include.

  Moreover, the calculating part 31 may distinguish the overcurrent state in the main breaker 40 into a plurality of stages and determine the degree of overcurrent. Specifically, the calculation unit 31 has a predetermined first threshold value that is lower than the rated power in the entire house that can be used by the electrical device 9 in the house, a second threshold value that is 90% of the rating, and a first threshold value that is 100% of the rating. Three threshold values and a fourth threshold value of 120% of the rating are set in advance. Then, in the calculation unit 31, the power usage amount of the main breaker 40 detected by the main current detection unit 32 and notified from the power calculation unit 33 is any value with respect to the first threshold value to the fourth threshold value. It is determined whether or not.

  When the power usage amount of the main breaker 40 is equal to or less than the first threshold value, the calculation unit 31 determines that no overcurrent has occurred. The calculation unit 31 also has a first overcurrent state where the first threshold value <the power usage amount of the main breaker 40 ≦ the second threshold value, and the second threshold <the power usage amount of the main breaker 40 ≦ the second overcurrent condition that is the third threshold value Whether the current state, the third threshold value <the power usage amount of the main breaker 40 ≦ the third overcurrent state where the fourth threshold value is satisfied, or the fourth threshold value <the fourth overcurrent state where the power usage amount of the main breaker 40 is satisfied Determine. That is, the calculation unit 31 can also determine that the degree of overcurrent increases as the first overcurrent state, the second overcurrent state, the third overcurrent state, and the fourth overcurrent state are achieved.

  A database stored in the database storage unit 37 and operations referring to the database will be described with reference to FIGS.

  The database includes information on the electrical device 9 to be controlled by the energy management unit 2 shown in FIGS. 4 and 5, and which electrical device 9 reduces power consumption when an overcurrent is detected in the main breaker 40. And can be set by operating the control panel 7.

  Specifically, as illustrated in FIG. 4, the database storage unit 37 associates name information of the electrical device 9, an ID (identifier) of the electrical device 9, and address information of the electrical device 9. Remember the database. The database storage unit 37 stores the database shown in FIG. 4 with the data structure shown in FIGS. The database (first correspondence information) shown in FIG. 5A is information in which the device name information and the electric device ID corresponding to the device name are associated with each other. The database shown in FIG. 2 correspondence information) is information in which the electric device ID and the address information of the electric device 9 specified by the electric device ID are associated with each other.

  Further, as shown in FIG. 5C, the database storage unit 37 stores a controllable order set by a user operation on the control panel 7. This controllable rank is set as a rank that allows the control unit 31 to input the user's operation information and associate the name with the name of the electrical device 9 to allow the control of the power consumption of the electrical device 9 to be suppressed. This controllable order is the order set by the user judging that the power suppression control may be performed, and is in a reverse relation to the priority order of the electrical equipment 9 that gives priority to power supply. Thus, a setting means is comprised by the structure of the control panel 7 and the calculating part 31 which set a controllable order | rank.

  And the calculating part 31 reduces the power consumption of the electric equipment 9 with the high controllable order set like FIG.5 (c), when the overcurrent of the main breaker 40 is determined by the main current detection part 32. Alternatively, a control signal is transmitted to the electric device 9 so as to stop power consumption. At this time, the calculation unit 31 refers to the first correspondence information in FIG. 5A using the name of the electric device 9 associated with the controllable order as a key, and acquires the electric device ID to be controlled. With reference to the second correspondence information in FIG. 5B using the electric device ID as a key, the address information of the electric device 9 to be controlled can be acquired. Thereby, the calculating part 31 transmits the packet which contains the acquired address information as destination address information including the control signal which reduces power consumption.

  Examples of the control signal for reducing the power consumption include a command for turning off the power supply of the electrical device 9 and a command including a ratio for reducing the power consumption of the electrical device 9.

  Thereby, the energy management unit 2 reduces the power consumption by the operation of the user when the calculation unit 31 determines that the power consumption of the main breaker 40 measured by the main current detection unit 32 is an overcurrent. It is possible to preferentially control the electric device 9 set to be allowed.

  Moreover, the database memorize | stored in the database memory | storage part 37 may become as shown in FIG.6 and FIG.7. This database describes information on the electrical equipment 9 to be controlled by the energy management unit 2 and which electrical equipment 9 consumes less power when an overcurrent is detected in a certain main breaker 40. Yes, it can be set by operating the control panel 7.

  Specifically, as shown in FIG. 6, the database storage unit 37 includes location name information such as a living room or a kitchen in which the electrical device 9 is installed, an ID (identifier) of the electrical device 9, and the electrical device. A database in which 9 address information is associated is stored. The database storage unit 37 stores the database shown in FIG. 6 with the data structure shown in FIGS. The database (first correspondence information) shown in FIG. 7A is information in which the place name information is associated with the electric device ID corresponding to the place name. The database (first information) shown in FIG. 2 correspondence information) is information in which the electric device ID and the address information of the electric device 9 specified by the electric device ID are associated with each other.

  Further, as shown in FIG. 7C, the database storage unit 37 stores a controllable order set by a user operation on the control panel 7. This controllable rank is set as a rank that allows the control unit 31 to input the user's operation information and associate the location information with the place name to allow the control of the power consumption of the electrical device 9 to be suppressed. Thus, a setting means is comprised by the structure of the control panel 7 and the calculating part 31 which set a controllable order | rank.

  Then, when the main current detector 32 determines that the main current of the main breaker 40 is overcurrent, the arithmetic unit 31 is installed in a place where the controllable order set as shown in FIG. The control signal is transmitted to the electric device 9 so as to reduce the power consumption or stop the power consumption. At this time, using the place name associated with the controllable order as a key, the calculation unit 31 refers to the first correspondence information in FIG. 7A to obtain the electric device ID to be controlled, and the electric device With reference to the second correspondence information in FIG. 7B using the ID as a key, the address information of the electric device 9 to be controlled can be acquired. Thereby, the calculating part 31 transmits the packet which contains the acquired address information as destination address information including the control signal which reduces power consumption.

  Thereby, the energy management unit 2 reduces the power consumption by the operation of the user when the calculation unit 31 determines that the power consumption of the main breaker 40 measured by the main current detection unit 32 is an overcurrent. It is possible to preferentially control the electrical device 9 at the place where it is possible to set it. As a result, when an overcurrent of the main breaker 40 is detected, the energy management unit 2 increases the controllable order for the air conditioners installed in the living room, for example, and is installed in a Japanese room where there are many elderly people. The controllable order of the air conditioners that are used can be lowered, and when the overcurrent of the main breaker 40 is determined, the power consumption of the air conditioners installed in the living room can be reduced first.

  Furthermore, the energy management unit 2 stores in the database storage unit 37 the name information of the electrical device 9, the location name information where the electrical device 9 is installed, the identifier of the electrical device 9 installed at the location, and the electrical device. 9 address information is stored in association with each other, and is associated with the name of the electric device 9 and the controllable rank permitting the suppression control of power consumption of the electric device 9 is associated with the location name information. You may set the controllable order | rank which permits the suppression control of the power consumption of the electric equipment 9 installed in the place. In this case, when the calculation unit 31 determines an overcurrent in the main breaker 40, the electric device 9 having a higher controllable order is referred to by referring to the controllable order of the name of the electric device 9 and the controllable order of the place. The control signal is transmitted with reference to the electric device ID and address information associated with the electric device 9 and the place so as to reduce the power consumption or stop the power consumption. For example, when the controllable order of the name of the electric device 9 and the controllable order of the place are set, the calculation unit 31 performs an operation such as adding or multiplying the controllable ranks of the electric device 9 to obtain the electric device 9. The controllable order is obtained by combining the controllable order of the name of the name and the controllable order of the place.

  For example, when the controllable order is determined by multiplication, the controllable order of air conditioners in the entire house is “1” and the controllable order of floor heating in the entire house is “2”, while the living room in the entire house If the controllable order of “1” and the controllable order of a Japanese-style room where an elderly person is “5 (lowest)”, the controllable order of “living air conditioner” is “1”, “Japanese-style room” The controllable order of “No air conditioner” is “5”, the controllable order of “Living floor heating” is “2”, and the controllable order of “Japanese floor heating” is “10”. As a result, it is possible to avoid turning off “floor heating in the Japanese-style room” where there are elderly people and reducing power consumption simply by setting the controllable order of the Japanese-style room to “5 (lowest)”.

  Thus, when the overcurrent of the main breaker 40 is detected, for example, the energy management unit 2 lowers the controllable order for floor heating installed in a Japanese-style room where there are many elderly people. , Making it difficult to perform control to reduce power consumption for a specific electrical device 9 at a specific location, and conversely, specifying a specific electrical device 9 at a specific location to be controlled with priority given to reducing power consumption in the house Can do.

  As described above, according to the power management system, for example, a controllable order is set by presenting a screen as shown in FIG. In the example of setting the controllable order, the order in which the electrical device 9 is turned off is determined.

  As shown in FIG. 8A, the control panel 7 displays a peak cut setting screen for reducing the power consumption of the electrical device 9 when an overcurrent of the main breaker 40 occurs. This peak cut setting screen is displayed when the peak cut setting button 101 on the remote control setting screen of the electric device 9 as shown in FIG.

  In the peak cut setting screen of FIG. 8A, “electric power control is not possible” for the electric lock for setting the controllable order, “controllable order is first” for the living air conditioner, and “ "Do not cut" is set. This “impossible power control” is a setting state in which power control is not performed even when the main current of the main breaker 40 is generated, and “not turned off” is a time when the main current of the main breaker 40 is generated. In this setting state, the switch is not turned off, and “the controllable order is first” is a setting state in which power consumption is reduced with the highest priority when an overcurrent of the main breaker 40 occurs. When the next page button 103 is touched on this peak cut setting screen, a setting state related to the electric device 9 different from the electric device 9 displayed in FIG. 8A is displayed.

  Further, when the change button 102 is touched on the peak cut setting screen, as shown in FIG. 8D, the living air conditioner setting screen is displayed as to whether or not the living air conditioner is turned off at the time of overcurrent determination. Further, when the registration button 104 is touched with “OFF” selected on this selection screen, the living air conditioner setting screen shown in FIG. 8E is displayed, and the order in which the power is turned off (controllable order) is displayed. Let them choose. When “No. 1” is selected and the registration button 105 is selected, a confirmation including the message “Do you want to set the peak cut order of the living air conditioner first?” As shown in FIG. When the screen is displayed and the “Yes” determination button 106 is touched, the screen returns to the peak cut setting screen of FIG.

  On the other hand, when “Do not turn off” is selected while the living air conditioner setting screen of FIG. 8D is displayed and the registration button 104 is touch-operated, “Living air conditioner turned off” shown in FIG. When a confirmation screen including the message “Is not set” is displayed and the “Yes” determination button 107 is touched, the screen returns to the peak cut setting screen of FIG.

  Thus, according to the power management system, as shown in FIG. 8, it is selected whether the power consumption may be reduced at the time of overcurrent determination according to the name of the electric device 9 and the place where the electric device 9 is installed. The controllable order can be set intuitively and simply.

  In the power management system configured as described above, the calculation unit 31 corresponds to weighting information indicating which of the controllable order for the name of the electrical device 9 and the controllable order for the place name is prioritized. In addition, the electric device 9 that reduces power consumption may be determined using the controllable order and the weighting information. And the calculating part 31 considers the weight matched with the name or location name of the electric equipment 9 at the time of the overcurrent generation | occurrence | production of the main breaker 40, and transmits a control signal to the electric equipment 9 with a high controllable order. For example, in the case where the controllable order of “air conditioner” is “first” and the controllable order of “bathroom” is “first” among a plurality of places, When the weight is higher in the place than the name 9, the control signal can be transmitted with priority on the electric device 9 installed in the “bathroom”.

  Furthermore, in this power management system, the calculation unit 31 sets a flag that allows a reduction in power consumption and a flag that allows a power supply to be stopped for each controllable order for the plurality of electrical devices 9. And as shown in the operation | movement direction (1) of FIG. 9, after calculating so that the power consumption of the electric equipment 9 may be reduced in order with a high controllable order | rank, when the calculating part 31 is determined overcurrent, You may stop the electric power supply to the thing with a high controllable order among the electric equipment 9 in which the stop of an electric power supply is accept | permitted. As a result, the power management system can reliably avoid the overcurrent of the main breaker 40 without stopping the electrical device 9 as much as possible.

  Furthermore, in this power management system, the calculation unit 31 sets a flag that allows a reduction in power consumption and a flag that allows a power supply to be stopped for each controllable order for the plurality of electrical devices 9. And the calculating part 31 reduces the power consumption of the electric equipment 9 first, in order with a high controllable order, as shown to the operation | movement direction (2) of FIG. If the overcurrent of the main breaker 40 is still determined, the power supply is stopped when the power supply of the electric device 9 with reduced power consumption is allowed to stop. In this way, the operation of reducing the power consumption and the operation of stopping may be repeated in the order of the electrical devices 9 having the highest controllable order. Thereby, the power management system can perform the reduction control and the stop control in descending order of the controllable order, and can surely avoid the overcurrent of the main breaker 40.

  Furthermore, in this power management system, the calculation unit 31 sets a flag that allows a reduction in power consumption and a flag that allows a power supply to be stopped for each controllable order for the plurality of electrical devices 9. And as shown to the operation | movement direction (3) of FIG. 9, the calculating part 31 stops the electric power supply to the electric equipment 9 in which the stop of electric power supply is permitted, and when an overcurrent is determined. Of the electrical devices 9 that are operating, control may be performed to reduce the power consumption of the other electrical devices 9 in descending order of controllable order. Thus, the power management system can avoid the overcurrent of the main breaker 40 quickly and reliably by performing stop control before the reduction control.

  Furthermore, in this power management system, the arithmetic unit 31 sets a flag that allows a reduction in power consumption and a flag that allows a power supply to be stopped for each controllable order for the plurality of electrical devices 9. You may stop the electric power supply to the electric equipment 9 in which both reduction of power consumption and a stop of an electric power supply are accept | permitted in order with a high possibility order. As a result, the power management system can preferentially control the electrical device 9 that may be stopped, and reliably avoid the overcurrent of the main breaker 40.

  In this way, as shown in FIG. 9, the reduction control flag and the stop control flag are set for each controllable order. The reduction control flag and the stop control flag are for the place shown in FIG. The controllable order may also be set. For example, as shown in FIG. 9, for the living electrical appliance 9 with the controllable order “1” shown in FIG. 7C, the reduction control flag “◯” and the stop control flag that can reduce and stop power consumption are shown in FIG. 9. For the electrical equipment 9 in which “◯” is set and the controllable order shown in FIG. 7C is “4” in the Japanese-style room 9, as shown in FIG. 9, a reduction control flag “○” that can only reduce power consumption. ”And the stop control flag“ × ”are set. In this case, when an overcurrent is generated in the main breaker 40, first, the power consumption of the electric appliance 9 in the living room is reduced or reduced and stopped, and then the electric appliance 9 in the Japanese-style room is reduced. . Thereby, the suppression control of the electric power of the electric equipment 9 can be selected for each place by reduction and stop.

  Similarly, with regard to the controllable order as shown in FIG. 5C, a reduction control flag and a stop control flag may be set for each controllable order. For example, for the electrical equipment 9 of the air conditioner with the controllable order “1”, as shown in FIG. 9, a reduction control flag “◯” and a stop control flag “O” that can reduce and stop power consumption are set. For the IH heater electrical device 9 with the controllable order “4”, as shown in FIG. 9, a reduction control flag “◯” and a stop control flag “×” that can only reduce power consumption are set. ing. In this case, when an overcurrent occurs in the main breaker 40, first, the power consumption of the air conditioner is reduced or reduced and stopped, and then the power consumption of the IH heater is reduced. Thereby, the suppression control of electric power can be selected between reduction and stop for each type of the electric equipment 9.

  Thus, even when the controllable order according to the type of the electrical equipment 9 as shown in FIG. 5C and the controllable order according to the location as shown in FIG. 7C are set, FIG. As shown in Fig. 9, the power suppression control can be performed in the order of the operation direction (1), the order of the operation direction (2), or the order of the operation direction (3) in FIG. Or, if the overcurrent degree is smaller than the predetermined threshold due to a predetermined threshold and the degree of overcurrent described later, priority is given to reducing power consumption, and the overcurrent degree is larger than the predetermined threshold. The power supply may be stopped with priority.

  Further, when the electric device 9 that reduces the power consumption without stopping the power supply and the electric device that allows the power supply to be stopped are set, the calculation unit 31 generates an overcurrent of the main breaker 40. Sometimes, first, control is performed so that the power consumption of the electrical device 9 with the highest controllable order is the same. Thereafter, when an overcurrent is determined despite the reduction in power consumption of the electrical device 9, a control signal for turning off the electrical device 9 that is allowed to stop power supply is output. Thereby, the power management system can surely avoid the overcurrent of the main breaker 40.

  Furthermore, the calculation unit 31 stops the power supply to the electrical device 9 that is allowed to reduce power consumption when the degree of overcurrent is small, and stops the power supply when the degree of overcurrent is large. The power supply to the electrical equipment 9 that is allowed to stop may be stopped.

  Specifically, as described above, the calculation unit 31 has a first threshold value <a power usage amount of the main breaker 40 ≦ a first overcurrent state that is a second threshold value, and a second threshold <a power usage amount of the main breaker 40 ≦ The second overcurrent state that is the third threshold, the third threshold <the power usage of the main breaker 40 ≦ the third overcurrent state that is the fourth threshold, the fourth threshold <the fourth overcurrent that is the power usage of the main breaker 40 The current state is determined. That is, when the calculation unit 31 can determine that the degree of overcurrent increases as the first overcurrent state, the second overcurrent state, the third overcurrent state, and the fourth overcurrent state are achieved. When the degree of overcurrent is high as in the third overcurrent state or the fourth overcurrent state, the electric device 9 is allowed to stop power supply without performing control to reduce the power consumption of the electric device 9 The power supply to 9 may be stopped. Thereby, when the electric device 9 that can be turned off by the user's operation is set, the overcurrent state of the main breaker 40 can be quickly avoided by turning off the electric device 9.

  Further, when the overcurrent is determined after stopping the power supply to the electrical device 9 that is permitted to stop the power supply, the calculation unit 31 determines whether the other electrical device Control for reducing power consumption may be performed. As a result, when an overcurrent occurs in the main breaker 40, first, the power can be turned off from the electrical device 9 that can be turned off, and the power consumption of the electrical device 9 that does not turn off the other power can be reduced.

  Furthermore, when an overcurrent occurs in the main breaker 40, (1) first, the power consumption of the electrical device 9 is reduced and the electrical device 9 is turned off if the overcurrent state is not resolved. (2) The overcurrent state is high. When the electric device 9 is turned off suddenly, (3) First, when the electric device 9 having a high controllable order is turned off and the overcurrent state is not resolved, the three control methods of reducing the power consumption of the electric device 9 As described above, the operation (1) is performed when the first overcurrent state and the second overcurrent state are described above, and the operation (2) or (3) is performed for the third overcurrent state and the fourth overcurrent state. It may be set to be performed.
