That is, as shown in FIG. 2, the meter body 1 includes a wireless communication unit 6, an internal storage device 13, a CPU 14, a weighing unit 16, in addition to the display screen 2 and the external storage device insertion unit 3. A blocking device 17 and a communication unit 18 are provided.

  In the power meter 10 configured as described above, when power is supplied from a power supply side such as an electric power company, the measuring unit 16 measures the supplied power and outputs the measured value to the CPU 14.

  The CPU 14 is a part that controls the entire power meter 10 and has a calendar function. When the measurement value is output from the measurement unit 16, calendar information is added to the measurement value using a calendar function. Then, the measurement value to which the calendar information is added is written in the internal storage device 13 or displayed from the display screen 2.

  In addition to the measurement values being written in the internal storage device 13 in this way, unique set values (ID number, customer number, verification period, meter installation date, etc.) given in advance to each power meter 10 are stored. Has been written.

  The wireless communication unit 6 is provided in the vicinity of the external storage device insertion unit 3 and includes an antenna 11 and a transmission / reception circuit 12.

  When the contact-type external storage device 20 in which no data is written is inserted into the external storage device insertion unit 3, the CPU 14 sends the measurement value and the specific set value from the internal storage device 13 to the transmission / reception circuit 12. The transmission signal including these data is generated and transmitted from the antenna 11. The contact-type external storage device 20 writes data included in the transmission signal transmitted from the antenna 11 in this manner. The contact type external storage device 20 is preferably devised so that it can be discriminated from the appearance when no data is written.

  When the writing of data to the contact-type external storage device 20 is completed in this way, the CPU 14 operates the shut-off device 17 to shut off the power from the power supply side so that it is not supplied to consumers. The communication unit 18 transmits a notice to stop using the power meter 10 to the power supplier center device 4 through the wired communication line 5.

  On the other hand, when the contact type external storage device 20 in which data including the measurement value and the setting value unique to the power meter 10 is written is inserted into the external storage device insertion unit 3, the antenna 11 is connected to the contact type external storage device 20. A signal including the written data is received from the contact type external storage device 20. Then, the transmission / reception circuit 12 restores the set value and the measurement value, which are data written in the contact-type external storage device 20, from the signal received by the antenna 11, and writes it in the internal storage device 13. The contact-type external storage device 20 is preferably devised so that it can be discriminated from the appearance when data is written.

  In this way, when the writing of the data written in the contact type external storage device 20 to the internal storage device 13 is completed, the wireless communication unit 6 erases the data written in the contact type external storage device 20. . In addition, the CPU 14 operates the shut-off device 17 so that power from the power supply side is supplied to the consumer, and the power supplier center is connected from the communication unit 18 via the wired communication line 5. The apparatus 4 is made to transmit a use start notification of the power meter 10.

  Next, the operation of the power meter 10 to which the data takeover method according to the present embodiment configured as described above is applied will be described.

  First, when the power meter 10 is replaced or when the power meter 10 to be used is changed when a customer moves or the like, a stop procedure of the power meter that stops use will be described with reference to the flowchart of FIG.

  When electric power is supplied from an electric power supply side such as an electric power company to a consumer, the supply amount is measured by the measuring unit 16 of the electric power meter 10, and the measured value is output to the CPU 14 (S1).

  The measurement value output from the measurement unit 16 is written to the internal storage device 13 after the calendar information is added by the CPU 14 and displayed from the display screen 2 (S2). In addition to the measured values written in this manner, the internal storage device 13 has unique set values (ID number, customer number, verification period, meter installation date, etc.) given to each power meter 10. ) Is written in advance.

  When the power meter 10 is replaced or when the power meter 10 to be used is changed in response to a move of a customer (S3: Yes), the contact-type external storage device 20 such as an IC card is externally stored. It inserts in the apparatus insertion part 3 (S4). This contact-type external storage device 20 must be one in which no data is written.

  As described above, when the contact-type external storage device 20 in which no data is written is inserted into the external storage device insertion unit 3, the measurement value written in the internal storage device 13 and the specific set value are transmitted and received. A transmission signal obtained by the circuit 12 and further including these data is created and transmitted from the antenna 11 (S5).

  When the transmission signal is sent to the contact type external storage device 20 in this way, the data included in the transmission signal, that is, the measurement value and the specific set value are written in the contact type external storage device 20 (S6).

  When the writing of data to the contact-type external storage device 20 is completed in this way, the interruption device 17 is operated by the CPU 14 to cut off the power from the power supply side. As a result, power is not supplied to consumers. At this time, the communication unit 18 transmits a use stop notification of the power meter 10 to the power supplier center device 4 via the wired communication line 5 (S7).

  Thereby, the use stop process of the electric power meter 10 currently used is completed.

  Next, a procedure until the power meter 10 that is newly started to be used is described with reference to the flowchart of FIG.

  In order to make the power meter 10 to be used newly usable, in step S6, the contact type external storage device 20 in which the set value and the measured value specific to the power meter used so far are written, It inserts in the external storage device insertion part 3 of the electric power meter 10 newly used (S11).

  Then, a signal including data written in the contact type external storage device 20 is received by the antenna 11 (S12), and data written in the contact type external storage device 20 by the transmission / reception circuit 12 from the signal received by the antenna 11 is received. Are restored and written to the internal storage device 13 (S13).

  In this way, when the writing of the data written in the contact type external storage device 20 to the internal storage device 13 is completed, the data written in the contact type external storage device 20 is erased by the wireless communication unit 6. (S14). Thus, by erasing the data written in the contact type external storage device 20, the data written in the contact type external storage device 20 is reused, and the same data is also stored in another power meter. It is blocked from being written. As a result, only this power meter is writing the same data in its own internal storage device 13 as the data written in the internal storage device 13 of the power meter whose use has been previously stopped.

  Furthermore, the interruption device 17 is operated by the CPU 14 so that the power from the power supply side is supplied to the consumer. Further, the communication unit 18 transmits a use start notification of the power meter 10 to the power supplier center device 4 through the wired communication line 5 (S15).

  As described above, according to the power meter 10 to which the data takeover method according to the present embodiment according to the present embodiment is applied, the power meter 10 differs depending on the use of the contact type external storage device 20 due to the above-described operation. The set value and the measured value can be reliably transferred between the two power meters. Therefore, even if the power meter to be used is changed due to, for example, replacement, moving, etc., it is not necessary to newly set the changed power meter manually.

  This will reduce the entry work of measurement values, etc., prevent incorrect transcription, reduce the input work of set values, etc., and prevent incorrect settings. It is possible to prevent troubles with customers.

  Further, according to the power meter 10 to which the data takeover method according to the present embodiment according to the present embodiment is applied, the use of the power meter is stopped in accordance with the state of data transfer to the contact type external storage device 20, In addition, since it is possible to control the stage such as the start of use, it is possible to automatically stop the use of the power meter between the customer and the supplier, and automatically communicate or notify the start of use of the power meter. .

  When the writing of data from the contact-type external storage device 20 storing the data of the stopped power meter to the internal storage device 13 of the power meter to start using is completed, the data was written to the contact-type external storage device 20 Data can be erased. As a result, the data written in the contact-type external storage device 20 is reused, and it is possible to prevent the same data from being written to another power meter, which prevents unauthorized use. Reliability can be realized.

(Second Embodiment)
The power meter 30 to which the data takeover method according to the second embodiment of the present invention is applied has a configuration in which the power meter 10 to which the data takeover method according to the first embodiment is applied is partially modified. .

Further, the wireless communication unit 6 including the antenna 11 and the transmission / reception circuit 12 is configured to be able to transmit and receive data by the wireless communication 8 with the non-contact type external storage device 21 such as an IC tag.

  When the non-contact type external storage device 21 in which no data is written is brought close to the meter main body 1, the CPU 14 sends the measurement value and the setting value specific to the power meter 30 from the internal storage device 13 to the transmission / reception circuit 12. The transmission signal including these data is generated and transmitted from the antenna 11. The non-contact type external storage device 21 writes data included in the transmission signal transmitted from the antenna 11 in this way. The non-contact type external storage device 21 is preferably devised so that when no data is written, it can be discriminated from the appearance.

  On the other hand, when the non-contact type external storage device 21 in which the data including the measurement value and the setting value unique to the power meter 30 is written is brought close to the meter body 1, the antenna 11 is written into the non-contact type external storage device 21. A signal including the received data is received from the non-contact type external storage device 21. Then, the transmission / reception circuit 12 restores the setting value and the measurement value, which are data written in the non-contact type external storage device 21, from the signal received by the antenna 11, and writes it in the internal storage device 13. The non-contact type external storage device 21 is desirably devised so that it can be discriminated from the appearance when data is written.
