The controller 21 transmits the usage or discharge data received through the second communication module 25 to the meter reading server 10 in a normal operation, but receives a test signal from the meter reading server 10 and sends a signal corresponding thereto. After transmitting to the meter reading server 10, a reboot command is received from the metering server 10 reboots the intermediate meter 20.

In the energy meter reading system configured as described above, the user can determine whether an abnormal signal is received and detect which device has an error according to the following method, and can efficiently take appropriate measures for a device having a problem.

4 to 6 is a flow chart showing a maintenance method of the energy meter reading system according to an embodiment of the present invention. 4 to 6 may be performed by the control unit 11 of the meter reading server 10.

Referring to FIG. 4, in operation S11, data on energy consumption or greenhouse gas emission is received from the intermediate meter reading unit 20.

In step S12, it is determined whether the received data is abnormal. The abnormality can be determined as follows. When an error occurs in the measuring unit 40 or the intermediate communication devices, that is, the wireless communication units 30 and 31 or the intermediate metering unit 20, which constitute the energy metering system, a signal having a measured value of 0 is continuously received, A constant value signal is to be received. Therefore, when a predetermined reference time is set and a signal of 0 is received during the reference time or more, or a signal of a constant value is received, it may be determined that an abnormality has occurred.

If there is an error in the received data, the intermediate meter reading unit 20 is first tested in step S13. If the received data is intact, data is continuously received. The intermediate meter reading unit 20 may be connected to the meter reading server 10 by a LAN, and may transmit a test signal through the LAN, and then detect a signal returned to determine whether there is an abnormality. For example, when a normal signal is received by sending a ping signal to the intermediate metering unit 20, the intermediate metering unit 20 may determine that it operates normally. If the response signal is not received within a predetermined time, the intermediate metering unit ( It can be determined that the abnormality has occurred in 20).

If it is determined that there is an abnormality in the intermediate meter reading unit 20 in step S14, a reboot signal is transmitted to the intermediate meter reading unit 20 in step S15. If there is nothing wrong with the intermediate meter reading unit 20, there is a problem with the other communication devices, go to A to test other communication devices.

In step S16, if the reboot is successful, data reception is continued in step S17. Reboot success can be determined by sending a ping signal again to see if the normal signal is returned within a certain time. If you still reboot the middle meter reading unit 20, if there is still a problem, it is determined that the problem that can not be solved by rebooting the middle meter reading unit 20 to the mobile phone of the person in charge of the intermediate meter reading unit 20 in step (S18) Send SMS. In this case, the SMS message may include identification information of the intermediate meter reading unit 20 in which an abnormality occurs, for example, a serial number, a unique number, or location information in which the intermediate meter reading unit 20 is installed.

FIG. 5 is a flowchart illustrating steps subsequent to "A" in FIG. 4, and illustrates a test method of the wireless communication unit 30. The same method can be applied to both the server side wireless communication unit 30 and the measurement unit side wireless communication unit 31.

Referring to FIG. 5, in step S21, the wireless communication unit 30 is tested. The test of the wireless communication unit 30 may vary according to the model of the wireless communication unit 30. The wireless communication unit may use Parani-SD100 / 200 of Sena Technology, a Bluetooth device, and at this time, the test signal may be AT It can transmit the + BTRSSI signal. When using another device as the wireless communication unit 30 may transmit a test signal for checking the state of the device.

In step S22, it is checked whether there is an error in the wireless communication unit 30. If a response is normally received with respect to the test signal, it is determined that there is no abnormality. If the response is not received within a predetermined time, it may be determined that there is an abnormality.

If it is determined that there is an abnormality in the wireless communication unit 30, in step S23, a soft reset signal is transmitted to the wireless communication unit 30 to reset the wireless communication unit 30. At this time, the soft reset is an operation having the same effect as turning the power switch of the wireless communication unit 30 off and on. The connection with the other Bluetooth device is released and all the work being performed is stopped. According to an embodiment, when a device other than the Parani-SD100 / 200 device is used, a signal for resetting the corresponding device may be transmitted.

In step S24, it is determined whether the soft reset was successful. Success may be determined by transmitting a test signal again to determine whether there is a response within a predetermined time.

If the soft reset succeeds, data reception is continued in step S25. If the soft reset fails, the wireless communication unit 30 determines that a problem that cannot be solved by the reset has occurred, and an SMS text message is sent to the person in charge in step S26. Send it. In this case, the SMS text message may include identification information of the wireless communication unit 30 having a problem.

After the above operation is performed for the server-side wireless communication unit 30, it may also be performed for the measurement unit-side wireless communication unit 31.

FIG. 6 illustrates steps after “B” in FIG. 5, and illustrates a method of determining whether an error of a measuring unit measuring energy consumption or greenhouse gas emission is detected. The step of FIG. 6 may be performed when it is determined that there is no problem in the intermediate meter 20 and the wireless communication unit 30 or 31.

Referring to FIG. 6, in step S31, the measurement unit test signal is transmitted. The measuring unit 40 test signal may vary depending on which device is used as the measuring unit 40. The measuring instruments used as the measuring unit 40 generally have a function to test remotely, and may transmit a test signal corresponding thereto to determine whether or not the response signal is normally received.

If there is an error in the measuring unit, an SMS text message is sent to the person in charge in step S33. In this case, similarly, the text message may include identification information of the measurement unit 40. When it is determined that there is no abnormality in the measurement unit, since the data that is "0" or the data received with a constant value is actually measured normal data, the measurement data reception is continued in step S34.

As described above, the measurement unit 40 may use an Accura 3300 model of rootech company, and the model is not equipped with a function of remotely rebooting. However, when using a device having a function of remotely rebooting or resetting to the measuring unit 40 according to the embodiment, if it is determined that the measuring unit 40 has an error, first try rebooting or resetting. In case of failure, SMS can be sent to the person in charge.

The above description is merely illustrative of the technical idea of the present invention, and those skilled in the art to which the present invention pertains may make various modifications and changes without departing from the essential characteristics of the present invention.
