As shown in FIG. 1, the power supply device 1 a includes a smart meter 2 that transmits a “first identification signal” at a different frequency for each predetermined time period, and a plurality of receivers that receive the “first identification signal”. It is comprised by the outlet 3 classified by time zone.

As shown in FIG. 2A, in the smart meter 2, a signal related to the amount of power consumed by the device connected to the terminal portion 2a is sent to the measuring portion 2b (arrow A). The electric energy is obtained by the measuring unit 2b, and the result is sent to the computing unit 2c (arrow B). In the calculation unit 2c, calculation such as billing calculation is performed based on the amount of power measured by the measurement unit 2b, and the result is sent to the control unit 2d (arrow C). The results obtained by the processing of the weighing unit 2b and the calculation unit 2c are sent from the control unit 2d to the memory 2e and stored (arrow D).
The contents stored in the memory 2e are appropriately read from the memory 2e according to the instruction of the control unit 2d (arrow E), and then sent to the display unit 2f for display (arrow F).

  Furthermore, the smart meter 2 sends a signal indicating the time to the control unit 2d (arrow G), and sends a built-in clock 2g for managing the timing at which each process is performed, and a signal received from the outside to the control unit 2d ( Arrow H), communication unit 2h that receives information read from the memory 2e from the control unit 2d (arrow I), converts it to a signal, and transmits it to the outside, and inputs various information and instructions to the control unit 2d An input unit 2i used for (arrow J) is provided.

  As shown in FIG. 2 (b), the time zone outlet 3 receives the “first identification signal” transmitted from the communication unit 2h of the smart meter 2 and follows the instructions of the control unit 3c. A display unit 3d for displaying "second identification number", an input unit 3e used for inputting various information and instructions to the control unit 3c, and a memory 3f for storing information input from the input unit 3e And an insertion plug 3g to be inserted into an outlet installed on a wall, etc., an insertion port 3h into which an insertion plug of an electrical product or the like is inserted, and an electric power supplied from the outside through the insertion plug 3g. An opening / closing unit 3i that opens and closes a circuit supplied to the port 3h according to an instruction from the control unit 3c, and a lamp 3b that indicates a supply state of the power to the insertion port 3h.

  As shown in FIG. 3A, on the front face of the smart meter 2, there is provided a display unit 2f, and an input unit 2i including a screen switching button 4a, a confirmation button 4b, and operation buttons 4c and 4d. The display unit 2f uses the “identification number” used when inputting the “first identification number” using the “power amount display screen” indicating the measurement result by the measurement unit 2b and the confirmation button 4b and the operation buttons 4c and 4d. The “number input screen” is switched every time the screen switching button 4a is pressed.

  The “contract number” can be used as the “first identification number”. However, the “contract number” is a number assigned to a consumer from the power company based on a contract between the power company and the customer. In the smart meter 2, the “contract number” can be input one by one.

  The operation button 4c is used when changing an inputable digit, and the operation button 4d is used when changing an input value. In other words, the digit that can be input moves one by one to the right each time the upper triangle mark is pressed on the operation button 4c, and moves one by one to the left each time the lower triangle mark is pressed. The input value increases by 1 between 0 and 9 each time the upper triangle is pressed on the operation button 4d, and 1 between 0 and 9 every time the lower triangle is pressed. Get smaller.

  When the confirmation button 4b is pressed in a state where the “identification number input screen” is displayed on the display unit 2f, the number displayed on the screen is confirmed as the “first identification number”, and the information is stored in the control unit. 2d (see arrow J in FIG. 2 (a)). Further, the information related to the “first identification number” is sent from the control unit 2d to the memory 2e and stored (see arrow D in FIG. 2A). On the other hand, the communication unit 2h receives information on the “first identification number” from the control unit 2d, and transmits the “first identification signal” at a different frequency for each predetermined time zone according to the current time of the internal clock 2g. To do.

  As shown in FIG. 3B and FIG. 3C, the time zone outlet 3 has a display 3d on which an “identification number input screen” is displayed, and an input composed of a confirmation button 5a and operation buttons 5b and 5c. The portion 3e, the insertion port 3h, and the lamp 3b are provided on the front surface, and the insertion plug 3g is provided on the rear surface.

  As in the case of the smart meter 2, the “contract number” can be input one digit at a time zone outlet 3 as the “second identification number”. That is, when the triangle at the top of the operation button 5b is pressed while the display unit 3d is in the “identification number input screen”, the digits that can be entered move one by one to the right each time, and the triangle at the bottom When the mark is pressed, the digits that can be entered move one by one to the left.

In addition, when the upper triangle mark is pressed in the operation button 5c, the input value is increased by 1 between 0 and 9 each time, and when the lower triangle mark is pressed, the input value is increased each time. Decreases by 1 between 0 and 9. When the confirm button 5a is pressed in this state, the number displayed on the screen is confirmed as the “second identification number” and the information is sent to the control unit 3c (see arrow K in FIG. 2B). .
Further, the information related to the “second identification number” is sent from the control unit 3c to the memory 3f and stored (see arrow L in FIG. 2B). Further, the “second identification number” stored in the memory 3f is appropriately read according to an instruction from the control unit 3c and displayed on the display unit 3d (see an arrow M in FIG. 2B).

In this embodiment, “contract number” is used as “first identification number” and “second identification number”, but “model number” of smart meter 2 is replaced with “first number” instead of “contract number”. It can also be used as “1st identification number” and “second identification number”.
Since the “contract number” is different for each customer, when the “contract number” is used as the “first identification number” and the “second identification number”, the smart meter 2 and the outlet 3 of other consumers are used. There is no possibility that the “first identification number” and the “second identification number” are duplicated. Therefore, the reliability at the time of use increases.

  In addition, since the “model number” is different for each smart meter 2, when the “contract number” is used as the “first identification number” and the “second identification number”, the smart meter 2 and the outlet of another consumer are used. 3 and “first identification number” and “second identification number” are not likely to be duplicated, and “first identification number” regardless of whether there is a contract between the power company and the customer. And “second identification number” can be set. Therefore, for example, the “model number” of the smart meter 2 may be stored in advance as the “first identification number” and the “second identification number” in the memory 3 f of the outlet 3 at the time of factory shipment. it can. In this case, since it is not necessary for the consumer to set the “first identification number” and the “second identification number”, the “first identification number” and the “second identification number” by the consumer. Can prevent setting mistakes. Moreover, the input unit 3e and the display unit 3d are omitted from the outlet 3 for each time zone so that the structure is simple, and the manufacturing cost can be reduced.

  On the other hand, as shown in FIG. 4, in step S1, the “first identification signal” is transmitted at a predetermined frequency from the communication unit 2h of the smart meter 2, and the reception unit 3a receives this “first identification signal”. Then, the process proceeds from step S2 to step S3. The receiving unit 3a is configured to receive only a signal transmitted at a receivable frequency preset for each outlet 3 for each time zone.

The “first identification signal” received by the receiving unit 3a from the communication unit 2h of the smart meter 2 is sent to the control unit 3c (see arrow N in FIG. 2B), and in step S3, the control unit 3c stores the memory 3f. Is read in advance (see arrow O in FIG. 2B) and compared with the “first identification number” indicated by the “first identification signal”.
If the “first identification number” matches the “second identification number”, the control unit 3c sends an “operation signal” to the opening / closing unit 3i and the lamp 3b in step S4 (FIG. 2B). (See arrows P and Q). As a result, in step S5, the circuit connecting the insertion plug 3g and the insertion port 3h is closed by the opening / closing part 3i, and the lamp 3b is turned on.

  In step S3, the “first identification number” specified by the “first identification signal” issued by the communication unit 2h of the smart meter 2 matches the “second identification number” stored in the memory 3f. If not, the process returns to step S2. That is, if the “first identification number” and the “second identification number” do not match, the “operation signal” is not sent from the control unit 3c to the opening / closing unit 3i and the lamp 3b. The circuit connecting the mouth 3h is not closed, and the lamp 3b is not lit.

When the receiving unit 3a does not receive the “first identification signal” transmitted from the communication unit 2h of the smart meter 2, the process proceeds from step S6 to step S7 and then returns to step S2. In step S7, the circuit connecting the plug 3g and the plug 3h is opened by the opening / closing part 3i, and the lamp 3b is turned off.
That is, in the power supply device 1 a, the arrows R ₁ and R _{2 in} FIG. 2B are only displayed while the receiving unit 3 a receives the “first identification signal” transmitted from the communication unit 2 h of the smart meter 2. As shown, the electric power supplied from the outside via the plug 3g is supplied to the plug 3h.

  In the power supply device 1a having such a structure, the smart meter 2 is identified based on the “first identification number” and the “second identification number” by the outlet 3 for each time zone. There is no possibility that the time zone outlet 3 will erroneously receive the “first identification signal” from the smart meter having a “first identification number” different from the “number”. Moreover, the opening / closing part 3i of the outlet 3 for each time zone operates based on the current time of the built-in clock 2g of the smart meter 2.

FIG. 5 is a schematic diagram showing the configuration of Example 2 of the power supply apparatus according to the embodiment of the present invention.

  In the power supply device 1b having such a structure, it is visually confirmed by the lamp 6g of the aggregator 6 that there is a difference between the time of the radio clock 6b of the aggregator 6 and the time of the built-in clock 2g of the smart meter 2. It is notified to consumers. Therefore, the consumer can instantly know that the time of the built-in clock 2g of the smart meter 2 is deviated from the correct time without checking other clocks installed indoors or the like.

  As shown in FIG. 6B, the time zone outlet 7 includes a receiving unit 7a that receives the “second identification signal” and the “identification number setting signal” transmitted from the communication unit 6a of the aggregator 6, An input unit 7b used for inputting an instruction to the control unit 7c, a memory 7d in which a set “second identification number” or the like is stored, a plug 7e to be plugged into an outlet installed on a wall or the like, An insertion port 7f into which an insertion plug of an electrical product or the like is inserted, and a circuit (not shown) for supplying electric power supplied from the outside via the insertion plug 7e to the insertion port 7f are in accordance with instructions from the control unit 7c. An opening / closing part 7g that opens and closes, and a lamp 7h that indicates a state in which the power is supplied to the insertion port 7f and a state in which “second identification signal” and “identification number setting signal” described later can be received.

  As shown in FIG. 7A, on the front surface of the aggregator 6, a display unit 6d, an input unit 6e including a screen switching button 8a, a confirmation button 8b, and operation buttons 8c and 8d, and a lamp 6g are provided. Yes. The display unit 6d is used when inputting a “second identification number” using the “time display screen” indicating the “current time” of the radio timepiece 6b and the confirmation button 8b and the operation buttons 8c and 8d. The “identification number input screen” is switched every time the screen switching button 8a is pressed.

  The operation button 8c is used when changing an input digit, and the operation button 8d is used when changing an input value. In other words, the digit that can be input moves one by one to the right each time the upper triangular mark is pressed on the operation button 8c, and moves one by one to the left each time the lower triangular mark is pressed. Further, the input value increases by 1 between 0 and 9 each time the upper triangle is pressed on the operation button 8d, and 1 between 0 and 9 every time the lower triangle is pressed.

Further, the information on the “second identification number” is sent from the control unit 6c to the memory 6f and stored (see arrow B in FIG. 6A).
On the other hand, the communication unit 6a receives information on the “second identification number” from the control unit 6c (see the arrow C in FIG. 6A), converts it into an “identification number setting signal”, and transmits it.

  When the communication unit 6a receives the “first identification signal” transmitted from the communication unit 2h of the smart meter 2 in a predetermined time zone, the communication unit 6a sends the information to the control unit 6c (see arrow D in FIG. 6A). ). The control unit 6c determines the “current time” of the built-in clock 2g of the smart meter 2 obtained from the time when the communication unit 6a receives the “first identification signal” as the “current time” of the radio clock 6b (FIG. 6A). (See arrow E). When the difference between the two exceeds a predetermined value (for example, 1 minute), the control unit 6c gives an instruction to the lamp 6g (see arrow F in FIG. 6A) to turn on the light.

  The display unit 6d receives information read from the memory 6f (see arrow G in FIG. 6A), or information related to the “second identification number” and the “current time” of the radio clock 6b. (See arrow H in FIG. 6A) and displayed. Further, the communication unit 6a generates a “second identification signal” based on the “first identification signal” received from the communication unit 2h of the smart meter 2 according to an instruction from the control unit 6c. Make a call.

As shown in FIG. 7B and FIG. 7C, the time zone outlet 7 has an input unit 7b including an identification number setting signal reception button, an insertion port 7f, and a lamp 7h provided on the front surface. The plug 7e is provided on the back surface.
When setting the “second identification number”, when the identification number setting signal reception button of the input unit 7b is pressed in step S1 shown in FIG. 8, the signal is sent to the control unit 7c (FIG. 6B). ) (See arrow I). If the “second identification number” is not set, the process proceeds to step S7.
In step S2, operation signals are sent from the control unit 7c to the receiving unit 7a and the lamp 7h (see arrows J and K in FIG. 6B). As a result, the lamp 7h is turned on, and the receiving unit 7a can receive the “identification number setting signal” transmitted from the communication unit 6a of the aggregator 6.

When receiving the “identification number setting signal” issued by the communication unit 6a of the aggregator 6 in step S3, the receiving unit 7a sends it to the control unit 7c (see arrow L in FIG. 6B). After specifying the “second identification number” from the “identification number setting signal” in step S4, the control unit 7c sends the “second identification number” to the memory 7d and stores it in step S5 (FIG. 6). (See arrow M in (b)).
Further, in step S6, the control unit 7c sends operation signals to the receiving unit 7a and the lamp 7h (see arrows J and K in FIG. 6B). As a result, the lamp 7 is turned off, and the receiving unit 7a is released from the state where the “identification number setting signal” described above can be received.
When the identification number setting signal reception button of the input unit 7b is pressed, the lamp 7h is turned on again, and the receiving unit 7a is ready to receive the “identification number setting signal”.

In the receiving unit 7a, as in the case of the receiving unit 3a of the power supply device 1a, the frequency of a receivable signal is set in advance for each time zone outlet 7. Therefore, in step S7, when the receiving unit 7a can receive the “second identification signal” transmitted from the communication unit 6a of the aggregator 6 at a predetermined frequency, the control unit 7c stores the memory in the memory 7d in step S8. The stored “second identification number” is read (see arrow N in FIG. 5B), and the “first identification number” specified by the “second identification signal” received by the receiving unit 7a. "
If the numbers match, the control unit 7c sends an operation signal to the opening / closing unit 7g and the lamp 7h (see arrows O and K in FIG. 5B). As a result, in step S10, the circuit connecting the plug 7e and the plug 7f is closed by the opening / closing part 7g, and the lamp 7h is turned on.

  In step S8, the “first identification number” specified by the “second identification signal” issued by the communication unit 6a of the aggregator 6 matches the “second identification number” stored in the memory 7d. If not, the process returns to step S7. That is, when the “first identification number” and the “second identification number” do not match, the “operation signal” is not sent from the control unit 7c to the opening / closing unit 7g and the lamp 7h. The circuit connecting the mouth 7f is not closed, and the lamp 7h is not lit.

When the receiving unit 7a stops receiving the “second identification signal” transmitted from the communication unit 6a of the aggregator 6, the process proceeds from step S11 to step S12, and then returns to step S7. In step S12, the circuit connecting the plug 7e and the plug 7f is opened by the opening / closing part 7g, and the lamp 7h is turned off.
That is, in the power supply device 1b, the arrows P ₁ and P _{2 in} FIG. 6B are only displayed while the receiving unit 7a receives the “second identification signal” transmitted from the communication unit 6a of the aggregator 6. As shown in the diagram, the power supplied from the outside via the plug 7e is supplied to the plug 7f.

  In the power supply apparatus 1b having such a structure, since the “second identification number” is set for the outlet 7 by time zone using the aggregator 6, the outlet 7 by time zone has a display unit and “ There is no need to provide an operation button to be used when setting “2 identification number”. Therefore, the power supply device 1b is reduced in size, and the setting operation of the “second identification number” of the outlet 3 for each time zone becomes easy. As a result, it is possible to reduce restrictions on the installation location of the outlets 3 classified by time zone and to improve workability when installing the outlets 3 classified by time zone.

  Further, even when the built-in clock 2g of the smart meter 2 does not indicate an accurate time, the aggregator 6 transmits a “second identification signal” based on the radio clock 6b. Operates based on. Therefore, the consumer selects the outlet 7 for each time zone corresponding to the time zone where the electricity rate is cheap from the plurality of outlets 7 for each time zone in which the plug 7e is inserted into the outlet such as a wall. By inserting an insertion plug of an electrical product or the like into the insertion port 7f, it may occur when the time of the internal clock 2g of the smart meter 2 and the time of the clock installed indoors do not match. It is possible to avoid the problem that the electricity bill is not cheap as expected.

  As in the case of the power supply apparatus 1a, the “model number” of the smart meter 2 is used in the power supply apparatus 1b instead of using the “contract number” as the “first identification number” and the “second identification number”. "Can be used as" first identification number "and" second identification number ". In this case, the operation of setting the “second identification number” in the aggregator 6 is omitted by storing the “model number” of the smart meter 2 in the memory 7d in advance as the “second identification number”. Can do. This not only facilitates the handling of the power supply device 1b, but also eliminates the input unit 6e and the memory 6f of the aggregator 6 and the input unit 7b of the outlet 7 for each time zone, thereby simplifying the manufacturing cost. Reduction can be achieved.

  In the present embodiment, the “current time” of the smart meter 2 and the “current time” of the radio clock 6b are compared, and when it is determined that there is a difference of 1 minute or more, the control unit 6c sends an operation signal. However, the above-described time lag, which is a condition for the controller 6c to turn on the lamp 6g, is not limited to 1 minute or more, and can be changed as appropriate.

  It is an object of the present invention to prevent a consumer who is trying to use an electric product or the like by selecting a time zone with a low electricity rate so as not to suffer a disadvantage even if the built-in clock of the smart meter is not accurate. It is used as
