(Embodiment 1)

1 is a power system diagram in a home for explaining an outline of a power management device according to a first embodiment. This power management device is directly connected to a home appliance (for example, an air conditioner 210), and a power measurement control device 110 that manages the power consumption thereof, and a home appliance connected to the power measurement control device. It is composed of two kinds of devices of setting display device 100 for the resident to check the amount of power consumption from the remote site (for example, another room) and to operate for energy saving. ) Is connected. In this case, control signals, data, and the like are exchanged between the electric power meter control device 110 and the setting display device 100 by light line communication (also referred to as "PLC: Power Line Communication"). The outline of this light-line communication is described in 차세대 藤 健 et al., "Next-Generation Communication Known by Illustration" (Asahi Communications).

The power management device shown in FIG. 1 includes a setting display device 100 and five power measurement control devices 40, 50, 60, 70, and 110.

Hereinafter, the power consumption of the air conditioner 210 connected to the power measurement control device 110 will be described with reference to the case where the power measurement control device 110 and the setting display device 100 are controlled. .

2 is a block diagram showing a functional configuration of the power management device 10 according to the present embodiment. As shown in FIG. 2, the power management device 10 includes a power measurement control device 110 and a setting display device 100. In FIG. 2, for convenience, only one power measurement control device 110 is described in the light line 200, but a plurality of power measurement control devices having the same function are actually connected. In the power management device 10, by using the light line communication as described above, the integrated power amount upper limit set value, the interlocking setting flag, the reset signal, the opening and closing control signal from the setting display device 100 to the power measurement control device 110. Etc. are transmitted. The integrated power amount value, the open / close state flag, and the like are transmitted from the power measurement control device 110 to the setting display device 100. These details are mentioned later.

The power measurement control device 110 is a device installed between the existing outlet 202 and the home appliance 210, and supplies power to the home appliance 210 and enables energy saving. It is comprised by the measurement part 111, the light wire communication part 113, the comparison calculation part 114, and the shielding control part 115. As shown in FIG. Therefore, the power measurement control device 110 includes a male outlet 181 and a female outlet 182.

The integrated power measurement unit 111 measures the amount of power consumed by the household electrical appliance 210 based on the voltage between the electric light wires supplying power to the household electrical appliance 210 and the current detected by the current sensor 112. The electric line value communication unit 113 and the comparison operation unit 114 are notified of the electric power value. In addition, when the integrated power measurement unit 111 receives the reset signal from the light line communication unit 113, the integrated power measurement unit 111 initializes the integrated power amount value to "0".

The shield control unit 115 controls the switch 116 to feed power to the outlet 182 when the open / close control signal received from the light line communication unit 113 or the comparison operation unit 114 is “1: open”. To block. Moreover, the shielding control part 115 detects the open / closed state of the switch 116, and notifies the light line communication part 113 of the result as an open / closed state flag.

The light line communication unit 113 controls the communication with the setting display device 100 connected by the same light line by superimposing signals on the light line connected through the outlet 181.

The comparison operation unit 114 is, for example, a microcomputer having a ROM or a RAM, and controls the entire power measurement control device 110. In addition, the comparison operation unit 114 compares the integrated power amount upper limit set value set by the setting unit 102 of the setting display device 100 with the integrated power amount value notified by the integrated power measurement unit 111, and the linkage setting flag is " 1 (interlock) &quot; and the integrated power amount value is larger, the switch 116 must be opened and the open / close control signal &quot; 1 &quot;

The setting display apparatus 100 presents the integrated power value received from the power measurement control apparatus 110 by light line communication to the occupant, or receives the necessary operation from the occupant, and measures each power connected directly to each home appliance. An apparatus for transmitting a control signal or the like to a control device, the display unit 101, a setting unit 102, a light line communication unit 103, a control unit 104, a storage unit 105, and the like. The setting display device 100 plugs the outlet 180 into the outlet 201, whereby the initialization processing is activated to start the operation.

The display unit 101 is, for example, a liquid crystal panel, and displays the integrated power amount value, the integrated power amount upper limit set value, and the like by the instruction of the control unit 104. The setting unit 102 accepts an operation from a resident, for example, using a panel switch. The light line communication unit 103 controls the transmission and reception of a signal overlapped on the light line like the light line communication unit 113 of the power measurement control device 110. The control part 104 is a microcomputer provided with ROM or RAM, for example, and controls the whole setting display apparatus 100. The storage unit 105 stores, for example, a value of the integrated power amount upper limit setting value or priority for each household electrical appliance set by the occupant in RAM, and the value of the integrated power amount or the interworking setting flag that is changed at predetermined time or from time to time. In addition, the storage unit 105 stores the accumulated total power amount target value for each month.

3 is an example of the data configuration stored in the storage unit 105 of the setting display device 100. Fig. 3A is an example of a management table for realizing energy saving for each home appliance, and for each home appliance name 106a, the integrated strategic amount upper limit set value 106b, integrated power amount value 106c, and interworking setting flag. 106d and priority 106e are stored. Fig. 3B is an example of a management table for realizing energy saving as a whole home, and the total accumulated target amount of electricity maximum upper limit target value 107a is stored.

Here, the "accumulated amount of electricity upper limit set value" is a value of the amount of power consumption aimed at the monthly energy saving in the household electrical appliance, and in principle, when the interlocking setting flag 106d is set to "1", The comparison operation unit 114 is controlled so that the feeding stops when the value exceeds the value. The "integrated power amount value" is an integrated value of the amount of power actually consumed in the household electrical appliance, and is a value updated every predetermined time (for example, one minute). An "interlocking setting flag" is a flag indicating whether energy saving is performed in association with the power management device 10 for the home appliance, and is set by the occupant. When energy saving is performed, it is set to "1", and when not saving, it is set to "0". "Priority" is a value indicating difficulty in determining whether to be an energy saving target, and "0" has the highest priority (that is, it is difficult to be the most energy saving target), and the larger the number is, Priority is low (that is, it is easy to target energy saving). In this case, it is assumed that home appliances with priority "0" are excluded from the energy saving target (for example, a refrigerator). Therefore, it becomes an object of energy saving from the home appliances with a high priority value in order. The "accumulated total power amount upper limit target value" is a target value of the power consumption amount of the whole household of the month, and when this value is exceeded, control of energy saving countermeasure is applied from home appliances with a high priority value.

Next, operation | movement of the power management apparatus 10 comprised as mentioned above is demonstrated.

First, the electric power measurement control device 110 is inserted into the integrated power measurement unit 111 by inserting the power measurement control device 110 between the home appliance 210 which is the energy saving target and the outlet 202 that is supplied with the home appliance 210. The measurement of the integrated value of the power consumption amount is thereby started. Since the measurement result is transmitted from the light line communication unit 113 to the setting display device 100 via the light line 200 as described above and displayed on the display unit 101, the occupant consumes the amount of power consumption of the home appliance 210. It becomes possible to check. When the inhabitant who has viewed this display thinks that the power supply of the home appliance 210 is to be stopped in order to save energy, the setting unit 102 performs an operation for performing "power supply stop". As a result, the control unit 104 generates the opening / closing control signal “1 (switch 116: open)” based on the operation received from the occupant, and transmits it to the power measurement control device 110 through the light line 200. do. Then, since the light line communication part 113 of the power measurement control apparatus 110 which received the open / close control signal transmits this open / close control signal to the shielding control part 115, it controls the switch 116 to "open." It becomes possible. In this case, the operation is easy even if the place where the home appliance 210 is installed and the resident operating the setting display device 100 are separated. For example, this is the case where the accumulated power amount of the home appliance 210 installed in two stages is checked by the setting display device 100 of one stage and operated for power supply stop. In addition, since the opening / closing state of the shielding control section 115 can also be confirmed by the display section 101, the home appliance can be operated again by easily energizing the setting section 102.

In addition, the operation in the case where energy saving is considered in consideration of convenience will be described. As described above, when the inhabitant operates the home appliance 210 while checking the accumulated power amount or the like in the setting display device 100, since it is determined from the operation state of the home appliance in a relatively short period, the standby power is reduced. Although it is effective for prevention of forgetting to turn off the home appliances in a room, etc., it is not enough energy saving effect alone. There is also a need for a function that can save energy by deliberately judging from a long operating state. For example, it is effective to set the upper limit of the monthly power consumption in each home appliance, and to have the function of automatically interrupting the power supply when the integrated value of the amount of electricity exceeds the upper limit. In this embodiment, the comparison operation part 114 corresponding to such a case is also provided. Based on the operation received from the resident via the setting unit 102, an upper limit set value of the integrated power amount of the home appliance 210 is set and stored in the storage unit 105. At the same time, a linkage setting flag of whether or not the linkage between this upper limit setting value and the above-described cutoff is enabled is also set and stored. As described above, the value of the interlocking setting flag is set to "1" in the case of performing energy saving control in association with the integrated power amount upper limit setting value, and "0" in the case of not interlocking.

4 is a flowchart showing the flow of processing in the comparison operation unit 114 in the case of performing energy saving control in association with the integrated power amount upper limit set value as described above. Initially, the light-line communication unit 113 sets an integrated power amount upper limit set value and an interlocking setting flag sent from the setting display device 100 through the light line 200 at a predetermined cycle (for example, one second cycle) or at an arbitrary timing. Enter (S401). Even if the integrated power amount upper limit set value is set, when the interlocking setting flag is set to "0 (not interlocked)" (S402: No), the following energy saving control is not performed.

Next, the comparison operation unit 114 receives the integrated power amount value transmitted from the integrated power measurement unit 111 (S403). If the integrated power amount value exceeds the integrated power amount upper limit set value (S404: Yes), the opening and closing control signal "1" is transmitted to the shielding control part 115 so that the switch 116 may be opened (shielded). S405). By this operation, the power supply to the home appliance 210 is stopped.

In addition, the integrated power measurement unit 111 can send a reset signal by an operation received from the occupant at an arbitrary timing, and can reset the integrated power amount value to "0" at that time. This reset signal is used before the comparison operation unit 114 operates or when the accumulated power amount value exceeds the upper limit.

In addition, the amount of power consumption of all home appliances in the home is counted, so that when the total amount of integrated power of the counting result exceeds a certain value, the power supply is stopped in order from the insignificant (ie, low priority) home appliances. Energy saving control can also be performed.

5 is a communication sequence diagram between the setting display device and the power measurement control device in the case of performing energy saving control based on the accumulated total power amount and priority.

Initially, the setting display device 100 requests the home appliance 51 to transmit the integrated power amount value, and receives the integrated power amount value (S501, S502). Similarly, the setting display device 100 requests the home appliance 210 to transmit the integrated power amount value and receives the integrated power amount value (S503 and S504). Thereafter, the setting display device 100 aggregates the integrated power amount values of these devices (S505), and the value exceeds the integrated total power amount upper limit target value 107a of the month stored in the storage unit 105. If there is (S506), the home appliance having a large value of the priority 106e is identified (S507), and an opening / closing control signal is transmitted to the power measurement control device (S508) to control the power supply to be stopped (S509). .

As described above, according to the power management device 10 according to the first embodiment of the present invention, not only the power consumption of the home appliance 210 is measured, but also a signal from the setting display device 100 operated by the resident. Since the electricity can be shielded and controlled, it is possible to realize energy saving even if the occupant does not move directly to the place of the household electrical appliance from the monitoring result of the power consumption and operates. In addition, since the energization of the home appliance can be controlled in conjunction with the upper limit of the consumption strategy amount set by the occupant, it is possible to realize more convenient energy saving.

(Embodiment 2)

In this embodiment, an air conditioner is mentioned as an electrical appliance. In general, the air conditioner has the largest proportion of power consumption among household appliances used at home. Therefore, when considering energy saving measures at home, an air conditioner is an essential household appliance. However, since the air conditioner directly forms the warm environment of the room, simply stopping the operation of the main body causes a great discomfort to the occupants. Therefore, when making the quantity of electric power of an air conditioner the object of energy saving, very fine control, such as adjustment of a set temperature and adjustment of an air volume, is calculated | required.

With respect to such a problem, in the present invention, an infrared remote controller equipped with an air conditioner can be used to control not only the start / stop of power supply to the main body but also the range that can be set by the infrared remote controller. In this case, very fine energy saving control is performed.

6 is an external view showing the structure of the air conditioner in the present embodiment. As shown in FIG. 6, the air conditioner 160 is supplied with power through the power measurement control device 310 and the outlet 161. In addition, the power measurement control device 310 is connected to the setting display device 300 through the light line 200. In this case, the infrared receiver of the air conditioner 160 is covered with the infrared light-receiving prevention cover 125, so that the infrared signal cannot be directly received from the remote controller. Instead, on the side of the air conditioner 160, the power measurement control device 310 receives a remote control signal and supplies an infrared signal to the air conditioner 160 through the optical fiber 124, so that the infrared light receiving unit 123 is provided. And a signal relay device 126 having a light emitting unit (not shown).

7 is a block diagram showing a functional configuration of the power management device 20 according to the second embodiment. The difference between the power management device 20 according to the present embodiment and the power management device 10 according to the first embodiment is that the air conditioner 160 is intended as a home appliance. In addition, below, the same code | symbol is attached | subjected about the structure same as the said Embodiment 1, and the description is abbreviate | omitted.

In the power management device 30 of the present embodiment, as a new constitution that is not present in the first embodiment, the occupant has an air conditioner 160, an outlet 161 for supplying power to the air conditioner, and the air conditioner 160. The infrared remote control unit 162 to be used, the infrared light receiving unit 123 for receiving infrared rays transmitted from the infrared remote control unit 162, and the signals received by the infrared light receiving unit 123 are acquired as they are, and the light line communication unit 113 is used as the air conditioner setting state data. The remote control signal acquisition unit 122 to receive the air conditioner setting state data, and to generate infrared signals irradiated from the infrared light emitting unit 121 to generate infrared signals to the infrared light receiving unit of the air conditioner. Infrared light emitting unit 121 for emitting light, optical fiber 124 for sending the infrared light emitted from the infrared light emitting unit 121 to the infrared light receiving unit of the air conditioner, air conditioner And an infrared light-receiving prevention cover 125 that shields the infrared light-receiving portion so that infrared rays do not enter directly.

In addition, although the function of the setting display apparatus 300 is basically the same as the setting display apparatus 100 of the said Embodiment 1, in order to enable control based on the various signals of the infrared remote control 162, it is attached to this. In addition, the functions of the control unit 304 and the storage unit 405 are expanded.

The basic functions of the light line communication unit 313 and the comparison operation unit 314 in the power measurement control device 310 are also the same as those of the light line communication unit 113 and the comparison operation unit 114 according to the first embodiment, but the infrared remote controller ( In addition to the various control signals of 162, a function for enabling generation, transmission and reception of air conditioning control data, and reception of air conditioning setting status data is added.

The remote control signal output unit 120 generates and transmits a control signal for controlling the air conditioner 160 to the infrared light emitting unit 121 based on the instruction of the comparison operation unit 314 or the light line communication unit 313. In addition, the remote control signal output part 120 transmits the control signal transmitted from the remote control signal acquisition part 122 to the infrared light emission part 121 as it is, when energy saving control is not performed.

The remote control signal acquisition unit 122 receives the remote control signal through the infrared light receiver 123 or transmits a remote control signal to the remote control signal output unit 120 and the light line communication unit 313.

Next, the operation of the power management device 30 configured as described above will be described. First, the integration measurement of the amount of power consumption is started in the integrated power measurement unit 111 by inserting the power measurement control device 310 between the outlet 202 to which the air conditioner 160 has been fed and the air conditioner 160. . The measurement result is displayed on the display unit 101 of the setting display device 300 via the light line 200 from the light line communication unit 313, and the amount of power consumption of the air conditioner 160 is presented to the occupant.

For example, the setting contents to the air conditioner 160 received from the infrared remote control unit 162 of the Japanese-style room is acquired by the infrared light receiving unit 123 and the remote control signal acquisition unit 122 of the power measurement control device 110. Since it is displayed on the display unit 101 of the setting display device via the light line 200 from the light line communication unit 113, for example, a resident of the living room can also monitor the setting contents of the air conditioner 160. In addition, the setting contents to the air conditioner 160 are ON / OFF, operation modes, such as air-conditioning and cooling room, setting temperature, air volume, wind direction, etc. which a resident sets from the infrared remote control attached to the normal air conditioner, It is transmitted from the signal acquisition part 122 to the light line communication part 313.

Since the infrared signal received from the occupant has the infrared light-receiving prevention cover 125 attached to the air conditioner 160, the infrared light receiving part of the power measurement control device 310 does not enter the infrared light-receiving portion of the air conditioner 160 directly ( 123 is received by the remote control signal acquisition unit 122, the remote control signal output unit 120, the infrared light emitting unit 121 and the optical fiber 124 to be sent to the light receiving unit of the air conditioner 160 to be processed. Therefore, the setting state of the air conditioner 160 and the air condition setting state grasped | ascertained by the remote control signal acquisition part 122 always correspond.

Here, the occupant thinks of saving energy for the air conditioner 160, and the power consumption amount of the air conditioner 160 and the setting state of the air conditioner 160 displayed on the display unit 101 of the setting display device 300 are viewed. When the operation for changing the set temperature is performed to the setting unit 102, the operation content is the light line communication unit 313 of the setting display device 300 and the light line communication unit of the light line 200 and the power measurement control device 310 ( Since it is transmitted to the remote control signal output unit 120 through 313, the air conditioner 160 can be controlled. For example, in order to save energy at the time of cooling, setting, such as raising 1 degreeC set temperature, can be performed through the setting display apparatus 100 in 1st stage with respect to the air conditioner 160 in 2nd stage.

In addition, when the amount of power consumption of the air conditioner exceeds a certain upper limit, the comparison calculation unit 114 may include a function that can be automatically shut off. Specifically, the control unit 304 of the setting display device 300 receives the setting of the upper limit setting value of the integrated power amount of the air conditioner 160 from the resident through the setting unit 102. At the same time, the setting of the linkage setting flag is also accepted.

8 is a flowchart showing the flow of processing by the comparison operation unit 314 in the present embodiment. Initially, the comparison operation unit 314 receives air conditioner setting state data from the remote control signal acquisition unit 122, and determines whether or not the power supply of the air conditioner 160 is "ON" (S801). Next, the comparison operation unit 314 receives the integrated power amount upper limit set value and the linkage setting flag transmitted from the setting display device 300 through the light line (S802). When the interlocking setting flag is "1" (S803: Yes), when the integrated power amount value is received from the integrated power measurement unit 111, and the integrated power amount value exceeds the integrated power amount upper limit set value (S805: Yes), the air conditioner control data for the "energy saving mode" is transmitted to the remote control signal output unit 120 so as to stop the air conditioner (S806). Here, the air conditioner control data for "energy saving mode" means the data which shows the control for suppressing power consumption by reducing relaxation of a set temperature, and air volume, for example.

As a result, the remote control signal output unit 120 generates a control signal for the "energy saving mode" and transmits it to the infrared light emitting unit 121. In addition, the infrared rays generated by the infrared light receiving unit 123 are sent to the air conditioner 160 via the optical fiber 124, and the control of the air conditioner is started. Here, the air conditioning control data for the "energy saving mode" may be control for stopping the power supply of the air conditioning 160. Further, even when the integrated power amount upper limit value is set once, it is also possible to invalidate the energy saving control by setting the interlocking flag to 0 (not interlocked).

In addition, the integrated power measuring unit 111 can send a reset signal from the setting unit 102 at an arbitrary timing, and can reset the integrated power amount value to "0" at that time. For this reason, it is effective when it is used before the comparison operation part 114 operates, or when the integrated power value exceeds the upper limit.

As described above, according to the power management device 20 according to the second embodiment, the power measurement control device 110 not only measures the amount of power consumption of the air conditioner 160, but also from the setting display device 100 operated by the resident. Since the air conditioner can be set by a signal, it is possible to realize energy saving even if the occupant confirms the amount of power consumption or the current air conditioner setting, and moves directly to the place of the air conditioner without any operation. In addition, since the amount of power consumption can be controlled by controlling the setting of the air conditioner in conjunction with the upper limit of the power consumption set by the occupant, it becomes possible to realize more convenient energy saving.

(Embodiment 3)

9 is a block diagram showing the functional configuration of the power management device 30 according to the third embodiment. The difference between the power management device and the second embodiment in the third embodiment of the present invention is that the presence member detecting device 140 is added. This makes it possible to provide a power management device that can realize energy saving without sacrificing as much as possible for the comfort of the occupants. In addition, below, the same code | symbol is attached | subjected about the structure similar to the said Embodiment 2, and the description is abbreviate | omitted.

The presence member detection apparatus 140 is comprised from the infrared sensor 130, the sensor signal detection part 131, and the light wire communication part 141, The infrared sensor 130 detects a human body as a thermal object, and the sensor signal detection part 131 ), The absence of the human body in the detection area of the infrared sensor is determined. In general, the detection area is often the whole room where the air conditioner is installed, and the signal from the sensor signal detection unit 131 becomes a signal of a room or an absence room.

The presence member detecting device 140 starts operation by connecting the outlet (male) 183 to the outlet (female) 202 and transmits the presence absence signal obtained from the sensor signal detection unit 131 via the light line communication unit 141. It is possible to send to the light line 200 in the home. The presence absence signal sent to the light line 200 can be received by the light line communication unit 113 of the power measurement control device 110. For this reason, the presence member detection apparatus 140 can be installed away from the power measurement control apparatus 110 normally installed next to the air conditioner 160, for example, the place where the state is good for human body detection, such as a ceiling of a room. Installation is possible. The setting display device 100 and the power measurement control device 110 are the same as the power management device in the second embodiment.

The comparison calculation unit 514 receives the presence absence signal from the presence member detecting device 140, sets the energy saving for the air conditioner when there is no person from the detection area of the sensor, and returns the original when the person returns to the area. By returning to the set value, the energy saving control which ensures comfort is automatically performed.

Next, the operation of the power management device 30 configured as described above will be described.

10 is a flowchart showing the flow of processing by the comparison operation unit 514 in the present embodiment.

Initially, the comparison operation unit 514 receives the integrated power amount upper limit set value, the linkage setting flag, and the presence-absence linkage setting flag transmitted from the setting display device 500 via the light line 200 (S1001). Here, when the presence member association setting flag is "1" (S1002: Yes), the presence member sensor signal is received from the presence member detection apparatus 140 (S1003), and it is discriminated whether it is "recovery" (S1004). ).

In the present room (S1004: Yes), when the presence absence flag is "0", the presence absence flag is set to "1", and the air conditioner data is stored as air conditioning control data (S1009).

On the other hand, when the presence absence flag is "1" in the room (S1005: No), the air conditioner setting data is stored as the air conditioner control data and the air conditioner data (S1006, S1007).

In the case of the absence, the comparison operation unit 514 checks the value of the existence absence flag, and when the value is "1", changes the flag value of the existence absence to "0" (S1011) and sets the energy saving air conditioner. The data is referred to as air conditioning control data (S1012).

Next, the comparison operation unit 514 outputs the value of the air conditioner control data to the remote control signal output unit 120 to control the air conditioner 160 (S1013).

In addition, the comparison operation unit 514 examines the value of the interworking setting flag, and when the value is "1", the integrated power amount value is received from the integrated power measurement unit 111 (S1015), and the integrated power amount value is the upper limit of the integrated power amount. If the set value is exceeded (S1016: Yes), control is made to stop the power supply to the air conditioner 160 (S1017, S1018).

Here, the relationship between the "absence member sensor signal" and "existent member flag" and the energy saving control in the air conditioner will be described. This "absence absence flag" is a flag for holding the value at the time of last input of the presence absence sensor signal input by a fixed period (for example, 1 second period). For example, if the present is absent (that is, the value of the present absence sensor signal is "0"), the previous time is occupied. Since it is considered that there is a change in the air conditioner, the air conditioner is controlled based on the energy saving air conditioner setting data. When the air conditioner control based on energy saving air conditioner setting data is cooling, for example, when it sets to "26 degreeC" again, the case where room temperature is set to "30 degreeC", etc. corresponds. In this "30 degreeC", although it feels quite unpleasant at the time of reexecution, it is set temperature effective for energy saving and it is effective for energy saving in absence.

On the other hand, if the present is occupied (ie, the absence sensor signal is "1") and the previous time is absent (i.e., the absent flag is "0"), it is considered that a person returns to the room and becomes occupied. The air conditioner data can be returned to the setting state of re-execution by giving the air conditioner a setting that has been saved. Of course, if there is no change in the room and the absence room, the setting change to the air conditioner is unnecessary.

In addition, as in the case of the second embodiment, even when the integrated power amount upper limit value is set once, it is also possible to invalidate the energy saving control by setting the interlocking flag to 0 (not interlocked). In addition, the integrated power measurement unit 111 can send a reset signal from the setting unit 102 at an arbitrary timing, and reset the integrated power value to zero at that time. For this reason, it is effective when used before the comparison operation part 114 operates, or when the integrated power value exceeds the upper limit.

As described above, according to the power management device 30 of the third embodiment, since the energy saving setting of the air conditioner is automatically performed only during the absence by interlocking with the presence absence signal of the presence absence detecting device 140, the occupant comfort Very few cases can be sacrificed, and energy saving with high convenience can be realized.

In addition, in the whole of this embodiment, in the comparison calculation part 114 of the power measurement control apparatus 110, the integrated power amount upper limit set value set by the setting part 102 of the setting display apparatus 100, and the integrated power measuring part 111 Although the control is performed by comparing the magnitudes of the integrated power amount values measured in the above, the comparison may be performed by converting the integrated power amount (electric charge) into the integrated power amount. In this case, in order to convert the integrated power amount measured by the integrated power measurement unit 111 into the amount of money, the power measurement control device 110 sets the value of the amount of money versus the amount of power in advance, and the setting unit 102 sets the upper limit to the amount of money. It is set.

In addition, in the whole of this embodiment, although the communication between the electric power metering control apparatus 110, the setting display apparatus 100, and the presence-absence detection apparatus 140 used the light line, the objective which can communicate by being separated from each other is provided. In order to achieve this, communication using wireless may be used.

As described above, according to the present invention, it is possible to realize energy saving even if the resident does not move directly to the place of the home appliance from the monitoring result of the amount of power consumption of the home appliance and perform the operation, and the operation of the resident can be performed very finely. It is possible to provide an electric power management device that can save energy without requiring as long as possible and without sacrificing as much as possible the comfort or convenience of the occupants.
