When the rating is set, the power consumption information providing module 426 matches the set rating to the user identification information, registers the rating in the power consumption information DB 422, 200, the home information management server 420 automatically stops the operation of the main device through the home management apparatus 200 when the rating information is high. As a result, power consumption can be controlled.

The electric energy management module 428 of the customer information terminal server 420 allows the user to set the amount of power consumption through the home management device 200. [

The electric energy management module 428 matches the electric power usage information set by the user with the user identification information and registers it in the electric energy management information DB 424.

Thereafter, the electric energy management module 428 checks the power consumption amount of the user who sets the electric power consumption amount, and determines whether or not the electric power consumption amount set in advance is exceeded. As a result of the determination, when the amount of power used by the user exceeds the amount of power to be set in advance, an excess amount is displayed on the screen of the home management apparatus 200 through the power line 500 and the watt-hour meter 100, .

Also, the electric energy management module 428 allows the home management device 200 to set a reception management device capable of shutting off the power when the user's electric power consumption exceeds a preset usage amount, and when the electric power consumption is exceeded The electric energy management module 428 determines whether the registered accommodation management device is in operation, and turns off the power supply when the registered accommodation management device is in operation, thereby turning off the accommodation management device.

On the other hand, the electric energy management module 428 sends an additional billing notice for the amount of power consumed by the user excessively.

Of course, the functions of the electric energy management module 428 can be implemented only by the home management apparatus 200. [ That is, the home management apparatus 200 may check the power consumption from the watt hour meter 100 and perform the same operation as described above.

As described above, according to the present invention, there is an effect that necessary information can be collected or provided through the home management apparatus based on the power line communication network, and the related devices can be monitored and controlled.

That is, since the bidirectional communication between the electric power company and the customer is possible, the present invention has an effect of establishing a basis for establishing an interactive customer management service and introducing a detailed fare plan.

In addition, the present invention is automatically calculated according to the progressive charge price. Even if the electricity tariff system changes, the data can be modified through bi-directional communication between the electric power company and the customer. It is possible to induce saving of consumption, and it is possible to easily apply the differential charge plan by time zone, thereby achieving remarkable achievement in peak time load management.

In addition, it has an effect of enabling the customer to induce a reasonable electricity consumption, to establish a power supply plan with improved economical efficiency by load leveling from the power company side, and to contribute to the energy overpower contribution nationwide.

The present invention also has the effect of expanding to high value-added communication services such as Home Service Aggregation (HSA) and remote meter reading integration of water, gas, and the like.

In addition, the present invention has an effect of enabling communication with all the electric devices in the premises through the watt-hour meter at the house entrance line by using the power line communication.

In addition, the present invention has an effect of realizing a useful service such as a real-time electricity price indicator, a time-based differential rate plan, an instantaneous overload warning, etc., which has not been feasible in the past, through a bidirectional communication function which is an advantage of power line communication.
