In the monthly usage screen of the large touch screen 72 in FIG. 5B, when a user of the home touch-clicks a button by power, gas, or water, the monthly usage of the corresponding item is displayed. At this time, it is preferable to display in a graph form that can be contrasted with each other day by day.

On the other hand, in the embodiment of the present invention, the meter reader enables the remote meter reading of the utility bill even through the door phone (6).

When the meter reader presses the meter button 62 of the door phone 6, the door phone 6 transmits the remote meter reading request data to the home server terminal device 4 by wire or wirelessly. Accordingly, the home server terminal device 4 is effective in response to the remote metering request, for example, various metered values stored in the memory unit 80, such as electric metering values, gas metering values, cold water and hot water (mainly effective for district heating or co-heating, etc.). Reads the water meter value, including the water meter value and transmits it to the door phone 6, and simultaneously displays the remote meter reading screen as shown in FIG. 6 on the large touch screen unit 72 of the home server terminal device 4).

When the door phone control unit 20 of the door phone 6 receives the measurement value data from the Hong server terminal device 4, the display phone 58 of the door phone 6 is divided into electricity, gas, and water, and the measured value is determined. It is displayed as shown in Figure 7 with the meter reading information.

Since the meter reading is made as described above, the meter reader can easily read the amount of utility bills in the home, and the user can check that the meter reading is made by the meter. Also, the meter readings read by the remote meter can be checked.

In the above description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be defined by the described embodiments, but should be determined by the equivalent of claims and claims.
