  When the measurement data acquisition timing comes again, the server control unit 33 causes the A route communication unit 31 to transmit a periodic measurement data request to the smart meter 10 (step S108). Here, it is assumed that a measurement data response is not transmitted from the smart meter 10 via the A route in response to the periodic measurement data request due to a communication abnormality in the A route. In this case, the server control unit 33 determines that an abnormality has occurred in the measurement data acquisition (step S109). Then, the server control unit 33 causes the public communication network communication unit 32 to transmit an abnormal measurement data request for requesting transmission of the measurement data to the smart meter 10 when an abnormality occurs (step S110). The abnormal measurement data request specifies the time of measurement data that could not be acquired due to the occurrence of an abnormality and makes a necessary data request.

  In the smart meter 10, the public communication network communication unit 14 receives the abnormal measurement data request transmitted from the server 30 via the public communication network.

  In the smart meter 10, the A route communication unit 12 receives the periodic measurement data request transmitted from the server 30 via the A route. Here, as described above, an abnormality has occurred in the measurement data stored in the smart meter 10. In this case, when the A route communication unit 12 receives the periodic measurement data request transmitted from the server 30, the smart meter control unit 15 sends a measurement data abnormality notification indicating that an abnormality has occurred in the measurement data for the A route. The communication unit 12 is transmitted to the server 30 (step S202).

The unit 32 is transmitted to the energy management apparatus 20 (step S204).

  In the energy management device 20, the communication unit for public communication network 22 receives the abnormal measurement data request transmitted from the server 30 via the public communication network. When the abnormality measurement data request is received by the public communication network communication unit 22, the energy management device control unit 23 reads out the measurement data received and accumulated in step S107 (step S205). Then, the energy management device control unit 23 causes the B-route communication unit 21 to transmit an abnormal measurement data response including the read measurement data to the smart meter 10 (step S301).

  As described above, in FIG. 4, the abnormal measurement data request transmitted from the server 30 corresponds to an instruction to the energy management apparatus 20 for causing the smart meter 10 to acquire measurement data.

  In the server 30, the server control unit 33 transmits the abnormal measurement data request to the energy management apparatus 20, and then causes the A route communication unit 31 to transmit the abnormal measurement data request to the smart meter 10 (step S303).

  In the smart meter 10, the communication unit 12 for A route receives the abnormality measurement data request transmitted from the server 30 via the A route. When the abnormal-time measurement data request is received by the A-route communication unit 12, the smart meter control unit 15 causes the A-route communication unit 12 to transmit an abnormal-time measurement data response including the recovered measurement data to the server 30 ( Step S304).

  In the server 30, the A-route communication unit 31 receives an abnormal measurement data response transmitted from the smart meter 10 via the A route. The server control unit 33 accumulates the measurement data included in the abnormal measurement data response received by the A-route communication unit 31 (step S305).

  As described above, when an abnormality occurs in the measurement data stored in the smart meter 10, the energy management device 20 transmits the measurement data to the smart meter 10. The smart meter 10 restores the measurement data in which an abnormality has occurred using the measurement data, and transmits the restored measurement data to the server 30. By doing so, the server 30 can acquire normal measurement data. In addition, the measurement data can be matched among the smart meter 10, the energy management device 20, and the server 30.
