Abstract

Disclosed herein is a power amount detection device respectively detecting power dissipated by each of various kinds of electric products and electronic gadgets of using commercial AC power, in which a plurality of outlet units confirms information of a load performing a communication with loads at the initial stage power is supplied through an outlet, integrates accumulating power amount used by a corresponding load, transmits electric amount and information of a corresponding load integrated at a unit time interval, and while inspecting entire power amount supplied to a plurality of outlet units, a server receives electric amount and information of a corresponding load transmitted by the plurality of outlet units to integratingly store electric amount for each load, and based on a signal of a key input part a server selects a load, and displays power amount of a selected load on a display part.

Claims

1. A power amount detecting device, characterized by:

a plurality of outlet units respectively installed at an outlet, acquiring information of a load communicating with the load when power is provided to the load through the outlet, and inspecting power amount used by a corresponding load and transmitting the inspected power amount with the information of load; and

a server integrating and inspecting and displaying entire power amount supplied to a plurality number of loads through the plurality of outlet units, and building-up a database based on information of loads transmitted by each of the plurality of outlet units and integrating power amount of a corresponding load, and displaying power amount of each of integrated loads.

2. The device of claim 1, wherein each of the plurality of outlet units is characterized by:

a power-amount detection part detecting power amount supplied to the load through the outlet;

a sub control part determining if power is supplied to the load through the outlet using an output signal of the power amount detection part, acquiring information of a load communicating with the load in a case power is supplied to the load, accumulating power amount detected by the power amount detection part, and transmitting accumulated power amount and the information of load to the server; and

a communication part performing communication with the load and the server under the control of the sub control unit.

3. The device of claim 2, further including a memory storing an operating program and a task data of the sub control unit as well as integratingly storing power amount detected by the power amount detection part under the control of the sub control part.

4. The device of claim 2, wherein a communication part of the plurality of outlet units is characterized by a PLC (Power Line Communication) part performing communication via the power line.

5. The device of claim 1, wherein each of the plurality of outlet units further includes a filter blocking data communicating with the load from being transmitted to other outlet units and the server in a case of communicating with the load.

6. The device of claim 1, wherein the server is characterized by:

a power amount detection part detecting an entire power amount supplied to the plurality of outlet units through a power line;

a communication part receiving information of a load and a power amount transmitted by the plurality of outlet units;

a main control part controlling to detect and display an entire inspected power amount by integrating an entire power amount having detected by the power amount detection part as well as integratingly storing a use power amount of a corresponding load for each type of load received by the communication part, and controlling a display of integratingly stored load-specified power amount; and

a display part displaying the entire inspected power amount and the load-specified power amount along with the control of the main control part.

7. The device of claim 6, wherein the communication part is characterized by a PLC (Power Line Communication) part performing communication via the power line.

8. The device of claim 6, further including a key input part for commanding the main control part to select a load and display power amount of a corresponding load.

9. The device of claim 6, further including an alram part alarming occurrence of electric leakage, and

wherein the main control part compares a grossed power amount entirely plusing an integratingly stored load-specified power amount with an overall inspected power amount, determines occurrence of an electric leakage as a comparison result if the overall inspected power amount is larger than the grossed power amount by more than a set value, and controls such that the alarm part produce an alarm.

10. The device of claim 6, further including a memory for storing the entire inspection power amount and load-specified power amount under the control of the main control part, and

wherein the main control part characterizingly builds a database in the memory for each load, and dividingly storing power amount of a corresponding load at a time basis and a data basis in the built database.

11. A power amount detection method, characterized by:

confirming information of loads communicating with the load by a sub control part in case power is supplied to loads through an outlet;

accumulating power amount supplied to the load; and

transmitting information of the load and the accumulated power amount to a server at a preset unit time interval.

12. The method of claim 11, wherein a communication of the sub control part and the load is characterized by a PLC (Power Line Communication).

13. The method of claim 11, wherein a transmission of information of the load and the accumulated power amount is performed in a PLC (Power Line Communication).

14. A power amount detection method, characterized by:

intergrating overall inspected power amount by inputting a detection signal of a power amount detection part by a control part;

gathering data transmitted from a plurality of outlet units by the control part and extracting information of load and power amount, and dividingly integrating the extracted power amount based on extracted information of load;

calculating a gross power amount plusing power amount integrated by dividing the each one of load, and determining occurrence of an electric leakage with a difference value of a calculated gross power amount and the overall inspected power amount; and

producing an alarm when occurrence of the electric leakage is determined.

15. The method of claim 14, wherein dividingly integrating the extracted power amount based on the extracted information of load is characterized in that the control part builds up a database for each load and dividingly integrates the extracted power amount.

16. The method of claim 14, further including selecting one of the plural loads by the control part based on a key signal of a key input part, and displaying accumulated integration power amount of a selected load on a display part.
