The following examples of the present invention are intended to embody the present invention, but not to limit or limit the scope of the present invention. From the detailed description and examples of the present invention, those skilled in the art to which the present invention pertains can easily be interpreted as belonging to the scope of the present invention.

First, Figure 1 shows a block diagram of a power management system according to an embodiment of the present invention.

As can be seen from Figure 1 power management system according to an embodiment of the present invention, the use condition storage unit 10, the control unit 20, the communication unit 30, the warning unit 40 and the user input unit 50 ).

The use condition storage unit 10 stores the use conditions for each of the plurality of electric devices, and if there is no interrupt request for the use of the plurality of electric devices from the user input unit 50, the respective use conditions are stored according to the use conditions. Allow the unit to operate. The electric appliance used in the present invention includes not only home appliances such as refrigerators and air conditioners used in homes, but also all kinds of appliances that operate on electricity.

Next, the controller 20 controls the operating conditions and power saving of a plurality of electrical devices. The communication unit 30 is between the use condition storage unit 10, the control unit 20, the warning unit 40, the user input unit 50 and a plurality of electrical devices, that is, between each component of the present invention, each component And transmit and receive signals between and a plurality of electrical devices. In addition, the communication unit 30 of the present invention can be implemented by various wired and wireless communication methods such as the Internet, 3G, Zigbee, WiFi.

The warning unit 40 of the present invention serves to generate an alarm signal when the power consumed by a plurality of electric devices as a whole exceeds a preset second ratio of the second set power for a second predetermined time. Do it. Examples of the display method of the warning signal include various display devices such as LEDs, e-mails, SMS, alarm sounds, and the like. An example of setting the second predetermined time may be 'one year'.

In addition, the user input unit 50 enables setting of operating conditions and the like of a plurality of electrical devices from users of the plurality of electrical devices. As an implementation example of the user input unit 50, an operation button provided in each of the plurality of electric devices may be used, or may be implemented by a separate user input device, or two methods may be mixed.

Specifically, the controller 20 of the present invention may control some or all of the plurality of electronic devices by the following four operation modes.

(1) On mode of operation: operates by turning on the power of electrical equipment

(2) Standby-off operation mode: The operation of the electrical equipment is off, but control by communication of each of the plurality of electrical equipment is possible.

(3) Communication error mode: Sends a warning signal to the user when an error occurs in the communication function of some or all of the electrical equipment

(4) Cold Off Mode: Sends a warning signal to the user as in the communication error mode with all power of the electric equipment including the communication function turned off.

In addition, the control unit 20 of the present invention can drive some or all of the plurality of electronic devices in the following four operation modes.

(1) Situational Awareness Mode: Using the information of the use condition storage unit 10, drive the electric device

(2) User Interrupt Mode: The electric device is operated by using the information input by the user through the user input unit 50.

(3) Power saving mode: By operating the automatic power saving function built into each of the electrical equipment, to operate the electrical equipment

(4) electric power company mode: driving electric appliances by electric power company demand management program

The operation of the power management system of the present invention will be described in more detail below.

The usage condition storage unit 10 stores initial values of the usage conditions of the plurality of electric devices, updates the usage conditions by using the accumulated information according to the use of the second predetermined time, and stores the usage condition information of the current stage. do. Specifically, the initial value of the use condition may be set by using power consumption in a standard operation mode for each of the plurality of electrical devices, or by receiving information from the user for each of the plurality of electric devices.

If the power consumption in the standard operating mode or user input value is not used as the initial value of the use condition, the non-standard flag is set for the electric device, and the electric device is used according to the use of a certain period of time. The initial value can be set using the information. For example, a non-standard electrical device may set initial values using information based on a minimum of four weeks (or one month) usage period, or, in the case of seasonal electrical equipment such as air conditioners, a minimum cycle of repeating usage patterns (e.g., For example, it is possible to reset the initial value by the average value of the power consumption measured per hour and 1 minute intervals per month. By this procedure it is possible to minimize the problems caused by the error of the information provided for each electrical device, of course.

2 illustrates one embodiment of an initial value of a use condition included in the use condition storage unit 10.

As can be seen from FIG. 2, the usage condition information to be stored in the usage condition storage unit 10 includes power consumption per hour, basic operating conditions, main use month, and average use per week for each of a plurality of electrical devices. Examples include information such as hourly or monthly average power usage. The use condition information also includes power saving priority information for determining the power saving order of a plurality of electric devices when power saving is required for the electric devices.

In addition, the renewal of the use condition is made by reflecting the actual use situation for a certain use period (second fixed time) for each of the plurality of electric devices.

3 illustrates an embodiment in which the use condition is updated.

Also, as can be seen from the comparison between Fig. 2 and Fig. 3, an update occurred in the main use month of the 'air conditioner'. The use condition stored in the use condition storage unit 10 of the present invention adopts a hierarchical structure, so that the change contents of the use month of FIG. 4, the change contents of the main use time of FIG. 5 (subtable 1), and the operation of FIG. 6. Various information such as the change mode of the mode (subtable 2) can be stored and used.

When the control unit 20 of the present invention receives an interrupt request for some or all of the electric devices from the user input unit 50, the control unit 20 operates the electric device under the condition set by the interrupt request, and requests an interrupt request from the user. The electrical device that has not been received may be controlled to operate under the use condition stored in the use condition storage unit 10.

The control unit 20 according to the present invention receives an interrupt request for some or all of the plurality of electric devices from the user input unit 50, and then operates the electric device under a condition set by the user in the first predetermined time. Afterwards, when the power consumed by the plurality of electric devices as a whole exceeds the first set power and the power consumption of the electric device that has received the interrupt request exceeds a preset power saving target value, the automatic power saving function built into the electric device is applied. Can be controlled to drive the electric device. An example of the first schedule time may be '4 weeks' or '1 month'.

In addition, it is preferable that the control unit 20 separates the valid information to be used for the update and the invalid (invalid) information not to be used for the update, and uses only the valid information for the use condition update. . The reason for separating valid information from invalid information is to filter information due to unexpected singular circumstances. For example, there may be an increase in the use of electricity due to a sudden inviting number of guests at home.

As a method of separating the valid information and the invalid information, the total power consumption of the plurality of electric devices during the second predetermined period according to the accumulated information according to the use is a reference value (the initial value of the use condition or the power consumption of the updated use condition). If exceeded, the accumulated information according to the use of each electric device is analyzed. The analysis of the accumulated information is performed in the unit of the first predetermined period, and the sub data belonging to the first predetermined period unit, that is, even one data belonging to the short period (the third predetermined period) forming the first predetermined period, If there is data that is 110% or less than the initial value or the power consumption of the updated use condition, the accumulated information according to the use of the electric appliance for the first predetermined period of time is determined to be valid information, and the information corresponding to the update of the use condition is determined. Can be used.

In other words, when the power consumption for one year exceeds the reference value, it is determined to be invalid on a monthly basis. If at least one of valid data in the weekly unit in the monthly unit exists, the corresponding month is determined to be valid data.

For example, assume that the usage information of the second predetermined period as shown in FIG. 7 is obtained in 2012 as shown in FIG. 2. Values underlined in FIG. 7 are values representing a result value different from the initial value of FIG. 2.

At this time, according to an embodiment of the present invention, the valid information is determined as follows.

Total Power Consumption in 2012

= (Monthly Power Consumption in Refrigerator * 12) + (Monthly Power Consumption in Washing Machine * 12) + (Consumption of Air Consumption in June + Monthly Power Consumption in Air Conditioners * 3) + (Monthly Power Consumption in TVs * 12) + (Monthly Power Consumption of Activity Light * 12)

= (39,239 * 12) + (3,729 * 12) + (91,000 + 45,500 * 3) + (11,648 * 12) + (5,839 * 12)

= 952.962 kWh

That is, the changed data that is not determined to be valid in the 2012 total power consumption of the data of FIG. 7 is reduced to the active reference value. The judging process is as follows.

(ID1 refrigerator)

1) Electric appliance power consumption (W / h) (default) = (53.9-49) /49=9.33% => valid data

The operating mode of the electrical appliance (default) depends on the electrical power consumption (W / h) (default).

(ID2 washing machine)

1) Weekly use time (default) = (6.6-6) / 6 = 10% => valid data

(ID3 air conditioner)

1) Major use month of electrical equipment (default) = (4-3) /3=33.33% => non-valid data

2) Validate weekly usage time (default) = (6-6) / 6 = 0% => valid data in June, 1) and 3).

3) Power consumption in June (default; W / M) => Ineffective data

4) Weekly weekly usage time (default) = (9-6) / 6 = 50% => non-valid data

5) Power consumption in August (default; W / M) = (68,250-45,500) / 45,500 = 50% => invalid data

The result of filtering the result value of FIG. 7 to the valid data having a deviation within 10% of the active reference value is shown as 'effective data of the total power consumption in 2012' of FIG. 8. Data determined to be valid data is underlined.

The result value of FIG. 8 is an update table which should replace and evaluate the 2012 active default value by accumulating and evaluating the situation information and user operation contents for one year in 2012. Since the estimated monthly power consumption exceeds the customer's power contract, the recommended power saving item is selected to present the user with a usage standard that does not exceed the power contract. The following is a detailed description of how to calculate the recommended power saving item.

First, to reduce the monthly power consumption by 10% based on the effective data of total power consumption so that the estimated power consumption by the recommended power saving item is less than the contract power. Calculate as value

The annual total estimated power consumption is calculated according to the final calculated value of FIG. 9 as follows.

Estimated total power consumption per year

= (Monthly Power Consumption of Refrigerator * 12) + (Monthly Power Consumption of Washing Machine * 12) + (Monthly Power Consumption of Air Conditioner * 4) + (Monthly Power Consumption of TV * 12) + (Month of Activity Light) Power consumption * 12)

= (37,519 * 12) + (3,413 * 12) + (42,513 * 3) + (11,392 * 12) + (5,220 * 12)

= 860,577 kWh.

The calculated results meet the power saving management requirements with a small value within 5% error of 860.746 kWh of power contract.

When converted into the recommended items for achieving the power saving target of the monthly power consumption calculated as shown in the underlined portion of the recommended power saving item of FIG.

That is, according to an exemplary embodiment of the present invention, when the power consumed by the plurality of electric devices as a whole exceeds the second set power for a second predetermined time period, the recommended power saving item is presented to the user. The recommended power saving item may be created by determining weights for each of the plurality of electric devices by using power saving priority information for determining the power saving order of the plurality of electric devices that are preset, and reflecting the determined weights.

11 is a flowchart illustrating a power management method according to an embodiment of the present invention.

As can be seen from Figure 11 power management method according to an embodiment of the present invention, the step of setting the initial value of the use condition of the plurality of electrical devices (S10), it is determined whether to receive the interrupt request from the user (S20), when receiving the interrupt request of step S20, acquiring the accumulated usage information according to the use of the first predetermined time of the plurality of electric devices (S30), and the whole of the plurality of electric devices for the first predetermined time It is determined whether the power to be used exceeds the first set power (S40).

According to the power management method of the present invention, when it is determined in step S40 that the first set power is not exceeded, the step of releasing the interrupt request from the user (S50) and whether the accumulated usage information of the second predetermined time has been obtained. The method may further include determining step S60.

In addition, if the accumulated usage information of the second predetermined time or more is obtained as a result of the determination in step S60, the method may further include updating the usage condition using the accumulated information according to the second predetermined time of use (S70). In addition, the power management method of the present invention, after the step S70, the result of the step (S80) and the step S80 of determining whether or not the power consumed by the entire electrical device exceeds the second set power for a second predetermined time When the second set power is exceeded, the method may further include presenting the recommended power saving item to the user (S90). The recommended power saving item may be created by determining weights for each of the plurality of electric devices by using power saving priority information for determining the power saving order of the plurality of electric devices that are preset, and reflecting the determined weights.

In the power management method of the present invention, when the determination result of step S80 does not exceed the second set power, it is preferable to update the continuous use condition by repeating steps S20 to S80.

Specifically, in step S70, it is preferable to separate valid information used for updating and invalid information not to be used for updating among the accumulated information resulting from the use, and use only valid information for updating the use condition.

In addition, in the power management method of the present invention, when the determination result of step S40 exceeds the first set power, the step of releasing the interrupt request from the user (S100) and the power consumption of the corresponding electric device that received the interrupt request in advance The method may further include determining whether the set power saving target value is exceeded (S110). In addition, when it is determined in step S110 that the power consumption of the electric device that has received the interrupt request exceeds a preset power saving target value, the power management method of the present invention operates by an automatic power saving function built in the electric device. It further comprises a step (S120).

In addition, as a result of the determination in step S110, when the power consumption of the electric device that has received the interrupt request does not exceed the preset power saving target value, the power consumption and information of the electric device are collected in predetermined time units (for example, one minute). And it accumulates (S130), it is carried out repeatedly from the step S50. In addition, even if the interrupt request of step S20 is not received, step S130 is performed.

12 is a detailed flowchart of step S10.

As can be seen from FIG. 12, specifically, step S10 includes requesting standard operation mode information for each of the plurality of electrical devices (S11) and determining whether to return the standard operation mode information (S12). do.

In operation S10 of the present invention, if the standard operation mode information is not returned as a result of the determination in step S12, the method may further include requesting initial value information to the user for the corresponding non-returned electric device (S13). . In the step S10 of the present invention, if the standard operation mode information is returned as a result of the determination in step S12, requesting standard power consumption information for each of the plurality of electrical devices (S14) and determining whether to return the standard power consumption information. Step S15 is further included. In addition, if the standard power consumption information is returned as a result of the determination in step S15, the initial value is set using the returned information (S16).

In addition, in step S10 of the present invention, if the standard power consumption information is not returned as a result of the determination in step S15, step S13 is performed. As a result of the request in step S13, it is determined whether the user agrees to the initial value setting (S17). If the user agrees in step S17, the initial value is set by the user input value (S18).

Specifically, when the power consumption in the standard operating mode or the user input value is not used as the initial value of the use condition, the non-standard flag is set for the corresponding electric device, and the use of a certain period of time for the electric device is used. The initial value may be set using the information according to S19. For example, a non-standard electrical device may set initial values using information based on a minimum of four weeks (or one month) usage period, or, in the case of seasonal electrical equipment such as air conditioners, a minimum cycle of repeating usage patterns (e.g., For example, it is possible to reset the initial value by the average value of the power consumption measured per hour and the one-minute interval for one month). Of course, the problem caused by the error of the information provided for each electrical device by this procedure can be minimized.

As described above, according to the power management system and the management method of the preferred embodiment of the present invention, it is possible to control a plurality of electrical devices using the situation awareness information. In addition, according to the present invention, when a power is used in one management unit (for example, one home) in excess of a power saving management target value, a user may propose an optimized power saving scheme.
