Description

Power system and method for controlling the operation of the device according to the target amount {SYSTEM FOR CONTROLLING DEVICES ACCORDING TO TARGET CHARGE AND METHOD THEREOF}

The present invention relates to a power system and method for controlling the operation of the device according to the target amount, and more particularly, it is possible to effectively induce the savings consciousness to the user to reduce the power consumption, specifically, the amount of electricity required by the user The present invention relates to a system and method for controlling power consumption of a device so that a fee for use (power usage fee) can be charged and optimally controlling power consumption of the device in consideration of various variables.

An electricity meter is an instrument that measures the power or amount of direct current or alternating current used in general homes, shopping malls, buildings, and factories.

The electricity meter can be classified into mechanical and electronic type according to its operation method.In the case of the electronic electricity meter, the meter has higher reliability and stability than the mechanical type, and has the advantage of miniaturization by integration of internal circuits. Electronic electricity meters are widely used.

In general, an electronic watt-hour meter includes a panel having a liquid crystal display unit at the front upper part of the main body, and a terminal block to which the wires of the input and output sides are connected is provided at the lower end of the panel, and a power supply state is provided inside the main body. At the same time as the current transformer is detected, the consumption is calculated and can be confirmed through the liquid crystal display. With such a configuration, the distribution company charges a fee to the user (consumer) by reading the value stored in the electricity meter, and the user uses the current amount as the amount of electricity. In other words, when using electricity in the customer, in order to know the current amount of power used, read the power value displayed on the electricity meter, or check the point of time when the fee is paid after a certain period of time.

In particular, a recent trend has been developed and applied to the remote meter reading system of the amount of power that can be received and read the data on the power consumption of each of the power consumers electronically measured through the electronic electricity meter remotely using a predetermined communication method to be. In the case of the remote meter reading system of the amount of electricity, the meter reading staff of the electricity supplier does not need to visit each customer to read the current amount of electricity displayed on the electricity meter.

However, the method of charging power according to the power consumption not only allows the user to know how much power he has consumed in a month, but also does not effectively raise the awareness of saving power to reduce power consumption in the future. have. In other words, the user recognizes how much power is actually used by checking power consumption in real time by bidirectional communication with the power supplier, but specifically, the user can adjust the power consumption so that the user is charged only for the desired amount. There is no situation.

In this regard, Korean Laid-Open Patent Publication No. 2003-0003233 (hereinafter referred to as 'prior document') allows the electric charge to be managed by controlling the amount of power used or maximum power of the electric load based on the target value, and affecting the facility. Disclosed is a technology for blocking or adjusting a power load that does not affect the power supply. The above-mentioned prior document merely discloses a configuration for cutting off the power to be supplied to a device that does not need power supply after distinguishing the device from the device that does not need power supply by calculating the amount of power that can be cut off for the target power amount.

However, the power consumption of the device is different depending on the situation or time due to various variables such as the type / specification of the device or indoor / outdoor temperature, there is a limit to automatically control the device optimally within the target amount. In particular, the prior literature only describes the contents of determining whether to reduce or cut off the power consumption of the load by determining whether the target power amount is exceeded, and specifically, the control method for limiting the power consumption of the load is of interest. Since there is no requirement, a method for efficiently controlling power consumption by controlling the amount of power directly input such as a heating and cooling device is required.

Korean Patent Publication No. 2003-0003233

The present invention can effectively inspire saving consciousness to the user to reduce the power consumption, and in particular, the power consumption of the device can be adjusted so that the user is charged only for the amount of money desired by the user, in consideration of various variables It is an object of the present invention to provide a system and method that can optimally control the power consumption of a device.

In addition, an object of the present invention is to enable not only automatic control of a new device placed in an existing space, but also automatic control of a device in a new space.

In order to achieve this object, the power system for controlling the operation of the device according to the target price according to the present invention includes a monitoring device, a control device and a server. The monitoring device is installed on a power line of each device in a predetermined space to monitor the power consumption of each device and transmit it through a communication module. The control device receives a control signal through a communication module, and controls the power consumption of each device based on the received control signal. The server receives information on the power consumption of each device from the monitoring device, and sends a control signal to the control device. Here, the server includes an information receiver, an information analyzer, a power consumption pattern database, a target amount input unit, a calculator, and a control signal output unit. The information receiving unit receives information on power consumption of each device from the monitoring device. The information analyzer analyzes a power consumption pattern of each device based on the received information. The power consumption pattern database stores power consumption pattern information of each analyzed device. The target amount input unit receives a target amount during the target period of the user from the user terminal. The operation unit converts the target amount of money into a target power amount based on the power consumption pattern information, and adjusts the power consumption of each device so that the sum of power consumption of each device in the space does not exceed the target power amount during the target period. Create a control command to control. The control signal output unit outputs a control signal including the control command to the control device.

By controlling them, there is an effect that can raise the awareness of power consumption more efficiently.

In particular, when the server receives and manages the target power amount in power units such as KW, it is difficult for the user to determine how appropriate the target power amount is set. However, in the present invention, since each device is controlled through the input of the amount of money, In addition, it is easy for users to use and can actively induce energy-saving consciousness through active participation of users, leading to economic power consumption pattern, thereby reducing power consumption more than necessary. .

In addition, since various device information and power consumption pattern information according to external variables are accumulated for each device, it is possible to calculate the expected rate and control the device within the target price. In other words, the operation data (operation time and setting variable) of the existing device, external variables such as outdoor temperature, indoor temperature, outdoor illuminance, indoor illuminance, location / direction of various sensors for controlling the device, the manufacturer, product type, Considering a lot of information affecting the power consumption of the device, such as product specifications, it is possible to optimally control the operation of the device within the target price.

In addition, it is possible to automatically control the devices in the new space as well as the automatic control of the new devices placed in the existing space by using the database information.

And even if the actual power usage exceeds the target power, the user may maintain the existing operating settings of a specific device according to the user's selection, or the user can directly enter the power consumption of the device through the user terminal to control the operation of the device, More efficient operation of the device is possible.

In addition, by providing the user with a short message service (SMS) or a website that the power consumption of each device may exceed the target power consumption for each time period / period, the user can be surely informed. It is effective to induce an economical power consumption pattern.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. Further, in the description of the embodiments of the present invention, specific values are merely examples, and exaggerated values may be presented for convenience and understanding of the present invention.

<Description of System>

1 is a schematic configuration diagram of a power system for controlling an operation of a device according to a target amount of money according to an embodiment of the present invention.

Referring to FIG. 1, the power system 100 includes a monitoring device 110, a device control device 120, and a server 130.

The monitoring device 110 is installed in the power line of each device 10 in a predetermined space (A) to monitor the power consumption of each device 10 in real time and transmit it through a communication module, air-conditioning equipment (air conditioner, heater) , Power consumption of various devices such as lighting equipment, TV, refrigerator, etc. are measured and transmitted to the server 130. The monitoring device 110 may be a smart meter, which is a kind of an electronic electricity meter that allows a user (consumer) to check the amount of money (fee, electricity bill) for each device and time period in real time. In addition, the space A defined in the present invention may be a home house, a coffee shop, a supermarket, a discount store, a fast food, a hospital, which need to control each device 10, but is not limited thereto. .

The device controller 120 receives a control signal from the server 130 through a communication module, and controls power consumption of each device 10 based on the received control signal. The device control device 120 may be an illuminance control device for controlling the power consumption of the lighting device by adjusting the illumination of the lighting device, the power of the air conditioning equipment by adjusting the set temperature and on / off of the heating and cooling device through the IR sensor. It may be a cooling and heating control device for controlling consumption.

The server 130 receives the information on the power consumption of each device 10 from the monitoring device 110, and transmits a control signal to the device control device 120, for this information receiving unit 131, information analysis unit 132, a power consumption pattern database 133, a target amount input unit 134, a calculation unit 135, and a control signal output unit 135.

The information receiving unit 131 may provide information on the power consumption of each device 10 from the monitoring device 110 for a certain period of time (one month or more than one year to specifically identify the user's standardized energy usage pattern through monitoring). ) Receive.

The information analyzer 132 analyzes the power consumption pattern of each device 10 based on the received information.

The power consumption pattern database 133 stores power consumption pattern information of each of the analyzed devices 10 and collects information in real time to increase the accuracy of device control based on the expected electric charge and the target price.

The target amount input unit 134 receives the target amount during the target period of the user from the user terminal 20 such as a general PC, a mobile phone, a PDA, or a smartphone. Electric bills usually come out on a monthly basis, the target period in the present invention is defined as a month, and thus the target amount means the amount according to the power consumption for a month. Since this can be changed according to a setting, it is not limited. When the target amount input unit 134 receives the target amount, the target amount settable range may be provided to the user based on the information analyzed by the information analyzing unit 132, and the target amount setter 134 may be input within the target amount settable range. desirable. This is to prevent each device 10 from operating unrealistically as the user inputs an excessively low target amount. Therefore, the user may check the target amount settable range output to the user terminal 20 and input or select the target amount targeted by the user.

On the other hand, the calculating unit 135 converts the target amount into a target amount of power based on the database power consumption pattern information, so that the sum of the power consumption of each device 10 in the space A during the target period is the target amount of power. A control command for controlling power consumption of each device 10 is generated so as not to exceed, that is, an electric charge due to the use of power within a target amount of power is charged.

The control signal output unit 136 outputs a control signal including the control command generated by the calculator 135 to the device controller 120.

In order to control the operation of the device 10 according to the target amount set by the user, first, it is necessary to calculate an accurate estimated rate based on the existing device operation behavior, and to the target amount set by the user by the reference reading date (target period) In order to fit, it is necessary to determine how the device 10 should be operated. Therefore, in order to calculate the expected rate and control the device within the target price, it is necessary to accumulate various device information and power consumption pattern information according to external variables for each device.

According to the present invention, the calculation unit 135 generates a control signal for controlling the power consumption of each device 10, referring to the power consumption pattern database 133, the power consumption pattern information of the device itself, a predetermined space ( The power consumption pattern information of the device similar to the device in A) and the power consumption pattern information of the device similar to the device in the other space are referred to.

First, the power consumption pattern information of the device itself is information on the operation pattern of the device 10 in the predetermined space (A), and is stored in the power consumption pattern database 133 for a predetermined period, so that the heating / heating device for each month / day / time zone It is possible to determine the average set temperature and illumination of the lighting equipment according to the time of day, and through this it is possible to predict the reliable estimated charges, it is possible to increase the accuracy of the device control.

At this time, when a new device is introduced into the space A while the power consumption patterns of the devices 10 in the space A are databased, the server 130 automatically controls the operation of the new device. ) Must receive and database the behavior patterns of this new device over a period of time. Therefore, in the present invention, before determining the power consumption pattern of the new device for a certain period of time, by controlling the operation of the new device using the power consumption pattern information of the existing device similar to the new device in the space (A), Even if a new device is placed in the space A, automatic control of the device can be performed within the target price without any problem.

In addition, before the power consumption pattern of the device in the new space is databased, the power consumption pattern information of the device similar to the device in the other space may be referred to so that the present invention may be applied to the new space.

Here, the calculation unit 135 refers to the power consumption pattern information of the device similar to the device in the predetermined space (A) and the power consumption pattern information of the device similar to the device in the other space (manufacturer, product type and It is desirable to select a device similar to each device based on the product specification information. That is, if the device is an air conditioner if the heater if, luminaire that the, or the manufacturer of the device is the Samsung cognitive, LG whether or cooling area of the air conditioning a few m ² if, cooling capacity is several W that the power consumption is several W Since the power consumption is different for each device, similar devices are selected in consideration of these variables. In addition, even if the air conditioner of the same product, even if the set temperature is 21 degrees, the power consumption is different when the external temperature is 25 degrees and 30 degrees, it is desirable to grasp the power consumption pattern according to the external variables for each device. The external temperature can be obtained through regional temperature information from the Meteorological Agency database or by a temperature sensor.

As such, the operation data (operation time and setting variables) of the existing device, external variables such as outdoor temperature, indoor temperature, outdoor illuminance, indoor illuminance, location / direction of various sensors for controlling the device, the manufacturer, product type, Considering a lot of information that affects the power consumption of the device, such as product specifications, it is possible to optimally control the operation of the device within the target amount.

For example, when the device is an air conditioner, external variables affecting power consumption may include outdoor temperature and indoor temperature. Even if the air conditioner is operated at 25 degrees, power consumption varies according to real-time external variables such as indoor / outdoor temperature, and the method of reducing power consumption of various types of air conditioners such as integrated, separate, and box type is different. Even if the set temperatures are the same, the power consumption varies depending on the type of air conditioner. Therefore, in order to accurately estimate the expected rate, it is necessary to secure abundant data on how the power consumption changes according to various variables. In addition, reasonable prediction of outdoor temperature is also required. This data is also needed to turn on / off the air conditioner and adjust the set temperature automatically according to real-time external / internal conditions to meet the target price set by the user.

The main variables for calculating the expected electric charges for air conditioners are future temperature, power usage patterns such as manufacturer, type, specification, and time / set temperature of the air conditioner. Calculation of the estimated rate for one month according to the use of the air conditioner can be briefly expressed as in Equation 1 below.

(1)

At this time, A is the expected value during the target period of the air conditioner, T _o (Δt) and T _s (j, Δt) is the external temperature and the set temperature during the time interval Δt, V is the space that can be accommodated Where p _max is the maximum capacity of the air conditioner, α is the correction constant according to the type of air conditioner, f is a function that converts the amount of power consumed during the unit time (Wh) with these variables as input, and h _conv is the amount of power Function to convert. In the future, the external temperature (T _o ) can be predicted through regional external temperature information from the Korea Meteorological Agency database, and can be replaced with a reasonable value such as last year's month or last year's yearly average.

For automatic control of the device according to the target price, the set temperature and on / off status are set for each time zone based on the target price, current usage fee, and estimated external temperature. It is calculated by Equation 2 below.

 (2)

T _s (Δt) is the set temperature for each time zone, A _obj is the target amount, p _used is the current consumption, V is the volume of space the air conditioner can accommodate, p _max is the maximum capacity of the air conditioner, α is the air conditioner T _avg (Δt) is the average external temperature for the time zone, T _o is the outdoor temperature, T _i is the indoor temperature, h ^-1 _conv is the function to convert the amount of power to the amount, and g is the variable. It is a function to calculate the set temperature to be set at a specific time as an input. This function also needs to be corrected by the accuracy, position, and orientation of the temperature sensor on which the feedback control is based. Therefore, in order to accurately estimate the estimated rate, it is necessary to secure abundant data on how the power consumption changes according to various variables. When the calculation unit 135 generates a control signal in consideration of a large amount of data and various variables, the air conditioner controller receiving the control unit controls the power consumption of the air conditioner by adjusting the set temperature and on / off of the air conditioner through the IR sensor. .

The same applies to lighting equipment. Let's look at the case of illuminance control, which is one of the saving methods mainly used in lighting equipment. In office spaces requiring fluorescent lighting, the brightness of fluorescent lighting required at 1 pm and 5 pm is inevitably different. A little dark light is enough for 1:00 pm, which is a lot of sunlight, compared to dim 5 pm. There is room for power savings when the outside is bright, rather than turning on fluorescent lights at full power all day long. Even in the case of such lighting equipment, in order to achieve the target price through accurate prediction of the estimated rate and automatic control, various variables such as outdoor illumination by time zone, change according to the position / direction of the illumination equipment, power consumption per unit time / illuminance by lighting equipment, etc. Therefore, abundant data on how power consumption changes is needed. The calculating unit 135 adjusts the illuminance of the lighting device to generate a control signal for controlling the power consumption of the lighting device, and the illumination control device receiving the control signal adjusts the illuminance of the lighting device according to the control signal. .

Such a configuration for operation and control is advantageously disposed on the server 130 of the service center that holds the information of the devices of each place at once, and is calculated for each place and device as the data accumulated in real time is enriched This is because the accuracy of device control based on the expected electric charges and the target amount can be increased.

On the other hand, in the present invention, by applying the priority of each device 10 through the information on the share of the power consumption of each device 10 in the actual total power consumption, assigning the target power amount for each device according to the priority, Provide this to the user. The priority and power consumption of each device 10 may be changed according to a user's selection. For example, as a result of analyzing the power consumption pattern, priority is given to air-conditioning equipment, lighting equipment, etc. in the order of the highest amount of electricity use in the month, and the percentage of decrease is lowered according to the priority. If provided to the user, it is applied according to the user's selection or the% value is adjusted. In other words, the user inputs the importance of each device from the user, and based on this, the target power amount is allocated to the low-importance device and the target power amount is allocated to the relatively important device. As described above, the user can flexibly control the device by changing the priority or allocation% for each device according to his or her preference.

To this end, the calculation unit 135 converts the target amount into target power amount for each device and time zone / period according to the analyzed information, so that the power consumption of each device 10 does not exceed the target power amount for each time zone / period. A control command for controlling the operation of each device 10 is generated for each period. If monthly electricity charges are 2 million won due to the use of 10,000KW of monthly electricity at the workplace, if the power consumption is monitored for each device for a fixed period (usually one month), the air conditioner, heater, lighting, TV, refrigerator, etc. The power consumption per device can be checked in real time through a web page on the user terminal 20 by accessing the Internet network. When the user inputs the target amount into the user terminal 20 after monitoring for one month, the server 130 converts the target amount into the target power amount based on the information about the power consumption of each device 10 and the target amount. This is to control the operation of the device 10.

When the user sets the target amount, the server 130 determines the energy usage according to the target amount by time zone / period, in the present embodiment, based on the monitoring result of the past month, and uses energy. According to the instructions to calculate what percentage of the device to be reduced, the device controller 120 controls the operation of each device (10). In other words, as a result of monitoring, the average amount of electricity used from 12 pm to 1 pm was 30,000 won, and among these, when the power use amount of HAVC (air conditioner, air conditioner, air conditioner) was 12,000 won, the user set the target price of 15,000 won. When set to Won, HAVC automatically controls the operation of HAVC to reduce the amount of electricity used to 6,000 won.

The calculation of the amount of electricity used analyzes the devices that can be actually saved based on the target amount to determine whether it is feasible, and calculates the amount of electricity on an hourly basis according to the user's power consumption pattern by time zone and day of the week. . If there is a change of seasons, for example, if the monitoring time is summer, and the use of HAVC decreases due to the fall, the setting of the target power amount for each device needs to be corrected. In this case, it is desirable to estimate the estimated electricity use amount based on last year's power usage information or by calculating the approximate amount of HAVC use based on the HAVC capacity and information.

According to the present invention, after monitoring the information on the power consumption of each device 10, if the user inputs the target amount during the target period to the user terminal 20, the server 130 the target amount of power The control signal is outputted so that the power usage amount of each device 10 does not exceed the target power amount during the target period, and the device controller 120 receives the control signal to control the operation of the device 10. As the user can control the devices 10 so that the power consumption can be made only as much as the target amount of money desired by the user, there is an effect of increasing the awareness of power consumption savings more efficiently.

In particular, when the server 130 receives and manages a target power amount in power units such as KW, it is difficult for a user to determine how much the target power amount is appropriate. However, in the present invention, the control of each device through the input of the amount of money is controlled. It is easy to use by the user, and can actively induce energy saving consciousness by the active participation of the user, leading to economic power consumption pattern, thereby reducing power consumption more than necessary It works.

On the other hand, it may be necessary to use more energy than the target amount of power corresponding to the currently set target amount due to seasonal changes. Therefore, immediately before the power usage amount of each device 10 exceeds the target power amount for each time zone / period, whether to control the operation of each device 10 according to the target power amount for each time zone / period, or for each device 10 by user input. It is preferable to inquire whether to control the operation of the &quot; If the target price of the air conditioner is set for each time period / day of the week for a month, the cumulative power consumption of the air conditioner on the 15th day may exceed the cumulative target power up to 15 days due to the continuous hot weather. In this case, since the server 130 has to adjust the power consumption of the air conditioner for the remaining 15 days, it is necessary to operate the air conditioner only during the daytime, or to increase the set temperature higher than the initial setting. However, as in the case where the workplace is a food manufacturing company, in a workplace where temperature maintenance is important, the set temperature and the operating time of the air conditioner must be kept constant, so the user may select to operate the air conditioner differently from the set operation. That is, in the present invention, even if the actual power usage exceeds the target power, the existing operating settings of the specific device may be maintained according to the user's selection, or the user may directly input the power consumption of the device through the user terminal 20 to Operation can also be controlled, enabling more efficient operation of the device in context.

Here, if it is selected to control the power consumption of each device 10 according to the target power amount by time zone / period, the short message service that the power usage of each device 10 may exceed the target power amount by time zone / period. : Short Message Service) or through the website. As described above, if the user decides not to follow the setting of the existing device, the user can be surely informed by informing that the target power amount may be exceeded, and the user can induce an economic power consumption pattern. There is.

In addition, the user can obtain information on energy use in real time through the website. If the reduction target is more than expected compared to the target amount set at the beginning of the month, for example, when the user turns off the HAVC power supply, the device fails, or inevitably does not use energy, The server 130 may be modified to lower the target amount according to the usage pattern so far according to the user's selection, and, on the contrary, may be modified to increase the power consumption of the device for the remaining period in order to meet the existing target amount. Operation of the device is possible.

<Description of Method>

A method of controlling the operation of the device according to the target amount of money according to the present invention will be described with reference to the exemplary diagrams shown in FIGS. 3 to 6 in addition to the flowchart shown in FIG.

1. Power consumption monitoring and transmission step <S201>

The monitoring device 110 installed on the power line of each device 10 in the predetermined space A monitors the power consumption of each device 10 and transmits it to the server 130 through the communication module.

2. Receiving Information on Power Consumption <S202>

The server 130 receives information on power consumption of various devices 10 such as a cooling device, a heating device, a lighting device, and the like from the monitoring device 110.

3. Analysis of power consumption pattern of each device <S203>

The information in step S202 is received for a certain period of time to analyze the power consumption pattern of each device 10. Here, the analyzed information includes the power consumption pattern and information on the share of the power consumption of each device in the total power consumption, and thus, the power consumption by device and time zone / period can be identified.

4. Storage step of power consumption pattern information of each device <S204>

The power consumption pattern information of each device 10 analyzed in step S203 is stored.

5. Target price input step <S205>

When the user inputs the target amount for the desired target period through the user terminal 20, it is received. For convenience of explanation, the target period is defined as one month, and accordingly, the target amount means the total amount according to the power consumption of all the devices for one month.

In this step, the target price settable range is provided to the user based on the information databased in step S204 (S205a), and the input is made within the target price settable range (S205b). This is to ensure that the target amount is determined within an appropriate range based on the analysis in step S203, and prevents each device 10 from being operated unrealistically as the user inputs the target amount excessively low.

6. Converting target amount to target amount of power <S206>

In step S204, the target amount of money is converted into a target power amount for each device and for each time period / period, based on the power consumption pattern information databased. That is, when the user inputs the target amount of money, the server 130 converts the target power into a corresponding amount of power, and divides the power consumption by device or time zone / period through the power consumption pattern information.

In this step, the priority of each device 10 is applied based on the information on the share of the power usage of each device 10 in the actual total power consumption, and the target power amount of each device is allocated according to the priority. For example, as a result of analyzing the power consumption pattern, if the heating and heating equipment, lighting equipment, etc. in the order of the highest amount of the total power consumption actually used during the month, priority is given in this order. And if given to the user by giving a reduction rate% relative to the actual power consumption as shown in Figure 3 according to the priority, the user may be able to control each device as it is after checking this, but prioritized by device according to their preferences B You can control the device flexibly by changing the% reduction rate (% of the allocation rate per device in the target power).

7. Satisfaction level inquiry <S207>

According to the allocation rate for each device in step S206, it is determined whether the available power usage amount allocated to each device 10 satisfies the desired target amount, and if it is not satisfied, the process returns to step S206 to request the user. And optimizing through the process of allocating power consumption for each device.

8. Control command generation step <S208>

The server 130 generates a control command for controlling the power consumption of each device 10 so that the sum of the power consumption of each device 10 in the space A does not exceed the target power amount during the target period.

9. Control signal output step <S209>

The control signal including the control command generated in step S208 is output to the device control apparatus 120.

10. Control of power consumption of the device <S210>

The device control device 120 receives the control signal from the server 130 through the communication module to control the power consumption of each device 10, by controlling the illuminance of the lighting device to control the power consumption of the lighting device. In addition, it is possible to control the power consumption of the air conditioning equipment by adjusting the set temperature and on / off of the air conditioning equipment through the IR sensor.

According to the present invention, the power consumption can be made only by the target amount desired by the user can more efficiently induce a sense of power consumption savings. In addition, since each device is controlled by inputting a target amount of money, it is easier for a user to understand than a target power amount input by a power unit such as KW, thereby inducing an economical power consumption pattern, and thus more power consumption than necessary. Can be reduced.

On the other hand, in order to control the operation of the device 10 according to the target amount set by the user in the present invention, it is necessary to first calculate the accurate estimated rate based on the existing device operation behavior, and the user until the reference reading date (target period) It is necessary to determine how to operate the device 10 to meet the set target amount. Therefore, in order to calculate the expected rate and control the device within the target amount, it is necessary to accumulate various device information and power consumption pattern information according to external variables for each device in real time.

In particular, in generating a control signal for controlling the power consumption of each device 10, the server 130 refers to the power consumption pattern database 133, the power consumption pattern information of the device itself, within a predetermined space (A) And power consumption pattern information of a device similar to the device and power consumption pattern information of a device similar to the device in another space.

First, the power consumption pattern information of the device itself is information on the operation pattern of the device 10 in the predetermined space (A), and is stored in the power consumption pattern database 133 for a predetermined period, so that the heating / heating device for each month / day / time zone It is possible to determine the average set temperature and illumination of the lighting equipment according to the time of day, and through this it is possible to predict the reliable estimated charges, it is possible to increase the accuracy of the device control.

As shown in FIG. 5, when the power consumption patterns of the devices 11 to 15 in the coffee shop A are in a database as shown in FIG. 4, the new device 16 in the coffee shop A is shown. In this case, in order to automatically control the new device 16, the server 130 needs to receive the operation pattern of the new device 16 from the monitoring device 110 and make a database for a certain period of time. Therefore, in the present invention, before grasping the power consumption pattern of the new device 16 for a certain period of time, the new device using the power consumption pattern information of the existing device 11 similar to the new device 16 in the coffee shop (A) By controlling the operation of (16), even if the new device 16 is installed in the coffee shop A, automatic control of the device 16 can be performed within the target price without problems.

In addition, the power consumption pattern information of a device similar to the device in the other space may be referred to before the database of the power consumption pattern of the device in the new space B so that the present invention can be applied to the new space B. have. For example, even before the power consumption patterns of the devices 31 to 34 of the factory B are databased as shown in FIG. 6, in order to automatically control the operations of the devices 31 to 34 using the present invention. First, the server 130 searches for devices 15, 41, 42, 71 similar to the devices 31-34 of the factory B, and the existing of the devices 15, 41, 42, 71. With reference to the power consumption pattern information to generate a control signal for controlling the operation of the devices (31 ~ 34) of the factory (B). In addition, the device controller receiving the control device controls the operations of the devices 31 to 34.

In this case, in order to refer to the power consumption pattern information of the similar device, it is preferable to select a device similar to each device based on the product number (manufacturer, product type and product specification) information of each device. That is, if the device is an air conditioner if the heater if, luminaire that the, or the manufacturer of the device is the Samsung cognitive, LG whether or cooling area of the air conditioning a few m ² if, cooling capacity is several W that the power consumption is several W Since the power consumption is different for each device, similar devices are selected in consideration of these variables. In addition, even if the air conditioner of the same product, even if the set temperature is 21 degrees, the power consumption is different when the external temperature is 25 degrees and 30 degrees, it is desirable to grasp the power consumption pattern according to the external variables for each device. The external temperature can be obtained through regional temperature information from the Meteorological Agency database or by a temperature sensor.

As such, the operation data (operation time and setting variables) of the existing device, external variables such as outdoor temperature, indoor temperature, outdoor illuminance, indoor illuminance, location / direction of various sensors for controlling the device, the manufacturer, product type, Considering a lot of information affecting the power consumption of the device, such as product specifications, it is possible to optimally control the operation of the device within the target amount.

For example, when the device is an air conditioner, external variables affecting power consumption may include outdoor temperature and indoor temperature. Even if the air conditioner is operated at 25 degrees, power consumption varies according to real-time external variables such as indoor / outdoor temperature, and the method of reducing power consumption of various types of air conditioners such as integrated, separate, and box type is different. Even if the set temperatures are the same, the power consumption varies depending on the type of air conditioner. Therefore, in order to accurately estimate the expected rate, it is necessary to secure abundant data on how the power consumption changes according to various variables. In addition, reasonable prediction of outdoor temperature is also required. This data is also needed to turn on / off the air conditioner and adjust the set temperature automatically according to real-time external / internal conditions to meet the target price set by the user.

The main variables for calculating the expected electric charges for air conditioners are future temperature, power usage patterns such as manufacturer, type, specification, and time / set temperature of the air conditioner. Calculation of the estimated rate for one month according to the use of the air conditioner can be briefly expressed as in Equation 1 below.

(1)

A is the expected value for the target period of the air conditioner, T _o (Δt) and T _s (j, Δt) are the external and set temperature during the time interval Δt, V is the volume of space that the air conditioner can accommodate, p _max is the maximum capacity of the air conditioner, α is the correction constant according to the type of air conditioner, f is a function that converts the amount of power (Wh) consumed during the unit time by inputting such a variable, h _conv is a function that converts the amount of power to money to be. In the future, the external temperature (T _o ) can be predicted through regional external temperature information from the Korea Meteorological Agency database, and can be replaced with a reasonable value such as last year's month or last year's yearly average.

For automatic control of the device according to the target price, the set temperature and on / off status are set for each time zone based on the target price, current usage fee, and estimated external temperature. It is calculated by Equation 2 below.

 (2)

T _s (Δt) is the set temperature for each time zone, A _obj is the target amount, p _used is the current consumption, V is the volume of space the air conditioner can accommodate, p _max is the maximum capacity of the air conditioner, α is the air conditioner T _avg (Δt) is the average external temperature for the time zone, T _o is the outdoor temperature, T _i is the indoor temperature, h ^-1 _conv is the function to convert the amount of power to the amount, and g is the variable. It is a function to calculate the set temperature to be set at a specific time as an input. This function also needs to be corrected by the accuracy, position, and orientation of the temperature sensor on which the feedback control is based. Therefore, in order to accurately estimate the estimated rate, it is necessary to secure abundant data on how the power consumption changes according to various variables. When the calculation unit 135 generates a control signal in consideration of a large amount of data and various variables, the air conditioner controller receiving the control unit controls the power consumption of the air conditioner by adjusting the set temperature and on / off of the air conditioner through the IR sensor. .

The same applies to lighting equipment. Let's look at the case of illuminance control, which is one of the saving methods mainly used in lighting equipment. In office spaces requiring fluorescent lighting, the brightness of fluorescent lighting required at 1 pm and 5 pm is inevitably different. A little dark light is enough for 1:00 pm, which is a lot of sunlight, compared to dim 5 pm. There is room for power savings when the outside is bright, rather than turning on fluorescent lights at full power all day long. Even in the case of such lighting equipment, in order to achieve the target price through accurate prediction of the estimated rate and automatic control, various variables such as outdoor illumination by time zone, change according to the position / direction of the illumination equipment, power consumption per unit time / illuminance by lighting equipment, etc. Therefore, abundant data on how power consumption changes is needed. The calculating unit 135 adjusts the illuminance of the lighting device to generate a control signal for controlling the power consumption of the lighting device, and the illumination control device receiving the control signal adjusts the illuminance of the lighting device according to the control signal. .

11. Monitoring of actual power consumption during the target period <S211>

It is monitored whether the actual power usage of each device is used within the target power during the target period as optimized in the step S207.

12. Reset after unexpected savings <S212>

As a result of the monitoring in step S211, if the reduction is more than expected compared to the target amount set at the beginning of the month, the server 130 may be reset to lower the target amount according to the usage pattern to date, on the contrary, the existing target amount It can also be reset to raise the device's power consumption for the remainder of the time. This is determined by the user's choice, and in this way, more realistic operation of the device is possible.

On the other hand, when more energy is used than the target amount of power corresponding to the set target amount, the following steps are performed.

13. Inquiry step immediately before exceeding target power amount <S213>

As a result of the monitoring in step S211, immediately before the power usage amount of each device 10 exceeds the target power amount for each time period / period, whether to control the operation of each device 10 according to the existing target power amount for each time period / period, or It is inquired whether the operation of each device 10 is to be controlled by the user's input.

14. Operation control step of the device as reset <S214>

When the power consumption is reduced more than expected in the step S212, and when the step S213 is selected to control the operation of each device 10 by the user's input, the server 130 resets each device 10 as a reset A control signal for controlling the operation is generated, and the device controller 120 receiving the control signal controls the operation of each device 10.

15. Excess notification step <S215>

In step S213, if it is selected to control the operation of each device 10 according to the existing target power amount for each time zone / period, the short message indicates that the power usage of each device 10 may exceed the target power for each time zone / period. Provided to users through SMS (Short Message Service) or website. This makes it clear to the user that the target power may be exceeded, and induces an economical power consumption pattern of the user.

16. Control the operation of the device according to the existing settings <S216>

In step S214, the power consumption of each device 10 is selected according to the target power amount for each time zone / period, and even if the power usage of each device 10 exceeds the target power for each time zone / period, Maintain power consumption. For example, even if the actual cumulative power consumption of the air conditioner up to 15 days of the month exceeds the target power amount of the air conditioner up to 15 days, the air conditioner target power amount is not adjusted for the remaining period of time. The operation of the air conditioner is controlled so that the electric power allocated to the air conditioner is used on a daily basis.

As described above, even if the actual power usage exceeds the target power, the user may maintain the existing operating settings of the specific device according to the user's selection, or the user may directly input the power consumption of the device through the user terminal 20 to Operation can also be controlled, enabling more efficient operation of the device in context.

On the other hand, the method for controlling the operation of the device according to the target amount according to the present invention may be implemented in the form of program instructions that can be executed by various computer means may be recorded on a computer readable medium.
