{Home Appliance Standby Power Learning Method based on Power Consumption Analysis}

The present invention relates to a home appliance information learning method, and more particularly, to a method of learning standby power of a home appliance connected to a smart outlet or a smart plug.

A technology that can automatically reduce standby power by automatically shutting off standby power when the home appliances connected to the smart outlet (or smart plug, etc.) are consuming standby power unnecessarily in standby mode It is equipped with many standby power auto disconnecting receptacles and smart receptacles (or smart plugs).

In order to automatically shut off the standby power, the standby power learning process is absolutely necessary before use. In the conventional method, it is necessary to let the user directly learn the outlet through some setting as below.

Conventional standby power learning process

1) Connect household appliances to standby power outlet (or smart outlet, smart plug).

2) Set home appliances to standby mode.

3) To measure the power consumed at this time, press the start learning button that is separately attached to the standby power outlet (or smart outlet, smart plug), or send the corresponding command to the standby power outlet , Smart plug) to learn the current standby power value.

However, the conventional art has the following problems.

a) The user should directly set the home appliance to standby mode, but many users do not know how to do it.

b) inconvenience of starting the standby power learning process

c) If the car outlet (or smart outlet, smart plug) changes, a reset procedure is required

d) The reconfiguration process is required even if the connected appliances change.

Hereinafter, the present invention will be described in detail with reference to the drawings.

1 is a diagram showing a system to which the present invention is applicable. A system to which the present invention can be applied is connected to a smart outlet / plug ('smart outlet or smart plug') 20 and a server 100 in a wireless and / or wire communication manner, as shown in FIG. 1 .

The server 100 analyzes the power consumption information of the home appliance 10 provided from the smart outlet / plug 20 to determine the standby power of the home appliance 10 connected to the smart outlet / plug 20 Learn.

The standby power determined by the server 100 is used to interrupt standby power by determining that the smart outlet / plug 20 has entered the standby state of the home appliance 10. [

As shown in FIG. 1, the server 100 includes a control application 110 and a standby power learning module 120.

The control application 110 is an application that performs the function of the server 100 itself. Specifically, the control application 110 monitors the power consumption information of the home appliance 10 provided from the smart outlet / plug 20 and manages / controls the smart outlet / plug 20 to ultimately control the home appliance 10 / RTI > the power supply / interception of the power supply to the < / RTI >

The standby power learning module 120 analyzes the power consumption information of the home appliance 10 provided from the smart outlet / plug 20 to calculate the standby power of the home appliance 10 connected to the smart outlet / Learn.

The standby power learning process by the standby power learning module 120 will be described below in detail with reference to FIG. Fig. 2 is a flowchart provided for explaining a home appliance standby power learning process.

2, when the power consumption information I of the household appliance 10 is input from the smart outlet / plug 20, the standby power learning module 120 determines which of the power consumption information I (S210).

Specifically, in step S210, the standby power learning module 120 determines whether 1) "I <REF (reference) _{lower limit} ", 2) "REF _{lower limit} I? REF _{upper limit} " and 3) "REF _{upper limit} < .

"I < REF _{lower limit} &quot;, the standby power learning module 120 increments the CNT (count) _{lower limit} by one (S220). On the other hand, if the "REF _{upper limit} &quot;is" I &quot;, the standby power learning module 120 increments the CNT _{upper limit} by one (S230).

When the counting result is "CNT _{lower limit} = n (reference value)" (S240-Y), the standby power learning module 120 sets the event flag to "FALLING" (S260). On the other hand, when the counting result is "CNT _{upper limit} = n" (S250-Y), the standby power learning module 120 sets the event flag to "RISING" (S270).

If the event flag is set to "FALLING" or "RISING" (S280-N), the standby power learning module 120 resets the REF to the power consumption information I input in the step S210 and sets the REF _{lower limit} and the CNT _{upper limit} And is reset according to the changed REF (S290).

On the other hand, if the event flag is not set to "FALLING" or "RISING" (S280-Y), the resetting of the REF, REF _{lower limit} and CNT _{upper limit} is not performed.

3 illustrates the power consumption information I of the household appliance 10 in which the "FALLING" event or the "RISING" event has not occurred. Here, 'n = 5' is assumed.

The power consumption information I shown in Fig. 3 does not deviate consecutively from the REF _{1 lower limit} [= (1 - epsilon) REF] by n (= 5) times. Accordingly, the " FALLING "event did not occur because the" CNT _{lower limit} = n (= 5) "

In addition, the power consumption information (I) shown in Figure 3 is _{the upper limit} REF ₁ [= (1 + ε) REF ] Subsequently not departing times n (= 5) a. Accordingly, the " RISING "event did not occur because the" CNT _{1 upper limit} = n (= 5) "

In this way, when the "FALLING" event or the "RISING" event does not occur, the power consumption information I of the household appliance 10 is treated as being maintained at "REF ₁ " Consumption patterns are simplified.

4 illustrates the power consumption information I of the household appliance 10 in which a "FALLING" event has occurred and a "RISING" event has occurred. Here, too, we will assume 'n = 5'.

The power consumption information I shown in FIG. 4 is consecutively deviated from the REF _{1 lower limit} [(1-epsilon) REF] n (= 5) times in the first blue display period. Accordingly, the "CNT _{lower limit} = n (= 5) &quot;, and a" FALLING "event is generated, thereby causing REF to decrease from REF ₁ to REF ₂ .

Also, the power consumption information I shown in FIG. 3 is consecutively deviated from the REF _{2 upper limit} [(1 +?) REF] n (= 5) times in the second blue display period. As a result, the "CNT _{upper limit} = n (= 5) &quot;, and a" RISING "event is generated, whereby REF has increased from REF ₂ to REF ₃ .

Referring again to FIG.

If the REF reset in step S290 is overlapped with the previously stored REF (S300-Y), the standby power learning module 120 does not store the reset REF and resumes from step S210.

For example, REF ₁ , REF ₃ and REF ₄ are stored. If the REF that is reset in step S 290 is REF ₃ , it is not stored redundantly.

However, if the reset REF is not overlapped with the stored REF (S300-N), the standby power learning module 120 additionally stores the reset REF (S310) and aligns the stored REFs in ascending order (S320).

For example, REF _1, REF _3, and there is REF ₄ are stored, if at S310 step stored REF ₂ are added _{(where, REF 1 <REF 2 <REF} 3 <REF 4), at S310 step REF are, REF ₁ → REF ₂ → REF ₃ → REF ₄ .

Then, the standby power learning module 120 updates the standby power value of the home appliance 10 (S330). In step S330, if the smallest REF among the stored REFs satisfies the following two conditions, the smallest REF is determined as the standby power. Here, REF ₁ is the smallest REF and REF ₂ is the _second small REF.

1) REF ₁ > 0

2) REF ₂ - REF ₁ > P

Here, w can be determined by a weighted number greater than 1 (for example, 2). That is, P is the average of the stored REF times the weight.

If the smallest REF of the stored REFs does not satisfy any of the above two conditions, the standby power of the home appliance 10 is treated as unknown.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the present invention.
