3 is a block diagram illustrating a process of transmitting information on the network system of the present invention.

3, in the network system of the present invention, a specific component can receive energy related information (hereinafter, "energy information 40 ") by communication means. (Environmental information, time information, etc.) in addition to the energy information 40. In this case, the information can be received from other components, that is, the received information includes at least energy information do.

The specific component 30 may be a component that constitutes the utility network 10 or a component that constitutes the home network 20. [

The energy information 40 may be one of electricity, water, gas, and the like as described above. Hereinafter, electricity is described as an example, but the same applies to other energy.

In one example, the types of information related to electricity include time-based pricing, energy curtailment, grid emergency, grid reliability, energy increment, (operation priority).

Such information can be divided into scheduled information generated in advance based on previous information and real time information that varies in real time. The schedule information and the real-time information can be classified according to the prediction of the information after the present time (future).

The energy information 40 may be transmitted or received as a true or false signal such as a Boolean on a network system, or the actual price may be transmitted or received, or may be transmitted and received in a plurality of levels.

The energy information 40 may be time of use (TOU) information, critical peak pattern (CPP) information, or real time pattern (RTP) information according to a change pattern of data over time.

According to the TOU information, data is changed stepwise according to time. According to the CPP information, the data changes stepwise or real-time with time, and emphasis is displayed at a specific time point. According to the RTP information, data changes in real time.

If the energy information is electricity rate information as an example, the information related to the electricity rate may vary. The electricity bill information may be transmitted or received as a true or false signal such as a Boolean on a network system, a real price may be transmitted or received, or a plurality of levels may be transmitted and received.

When the specific component 30 receives a true or false signal such as a Boolean signal, it can recognize that one signal is an on-peak signal and the other signal is an off-peak signal.

Alternatively, the specific component 30 may recognize information about at least one drive that includes the electricity bill, and the specific component 30 compares the recognized information value with a reference information value to determine an on-peak off-peak can be recognized.

For example, when the specific component 30 recognizes the leveled information or the actual pricing information, the specific component 30 compares the recognized information value with the reference information value to determine on-peak and off Recognize -peak.

At this time, the information value about the driving may be at least one of an electricity rate, a power rate, a rate of change of the electricity rate, a rate of change of the electric power rate, an average value of the electricity rate and an average value of the electric power amount. The reference information value includes a mean value of the energy charge, an average value of the minimum value and the maximum value of the power information (energy charge information) during a predetermined period, a reference change rate of the power information during a predetermined period (for example, a slope of power consumption per unit time) Lt; / RTI >

The reference information value may be set in real time or set in advance. The reference information value may be set in a utility network or set in a home network (input by a consumer direct input, energy management unit, central management unit, etc.).

When the specific component 30 (for example, the energy consuming unit) recognizes the on-peak (for example, the recognition time), the output may be set to 0 (stop or stop) and the output may be reduced. And, the output can be recovered or increased as needed. The specific component may determine the driving method in advance before starting the operation, or may change the driving method when the on-peak is recognized after the operation starts.

Alternatively, if the specific component 30 recognizes the on-peak (for example, the recognition time), the output is maintained if the operation condition is operable. At this time, the operable condition means that the information value of the driving is below a certain standard. The information value of the driving may be information on an electric charge, an amount of power consumption, or an operation time. The constant criterion may be a relative value or an absolute value.

The predetermined criteria may be set in real time or may be set in advance. The predetermined criteria may be set in the utility network or in a home network (input by a consumer direct input, energy management unit, central management unit, etc.).

Alternatively, the output may be increased when the specific component 30 recognizes the on-peak (for example, when it recognizes). However, even if the output increases at the time when the on-peak is recognized, the total output amount during the entire driving period of the specific component may be reduced or maintained to be less than the total output amount when the specific component operates at the normal output. Alternatively, even if the output increases at the time when the on-peak is recognized, the total consumed power or the total electricity charge during the entire driving period of the specific component is lower than the total consumed power or the total battery charge when the specific component operates at the normal output .

When the specific component 30 recognizes an off-peak (for example, when it recognizes), the output can be increased. For example, when the operation reservation is set, a component whose operation starts before a setting time or a component having a large output among a plurality of components can be driven first. Further, in the case of a refrigerator, it is possible to store the hot water by supercooling the output by increasing the output from the existing output, or by driving the heater in advance of the operation time of the heater in the case of the washing machine or the washing machine. Or if a particular component recognizes an off-peak (for example, when it recognizes it).

The energy curtailment information is information related to a mode in which the component is stopped or the electricity fee is reduced. The energy reduction information may be transmitted or received as a true or false signal, for example, as a Boolean on a network system.

When the specific component 30 recognizes the energy reduction information, the output can be set to 0 (stop or stop) and the output can be reduced as described above.

The emergency information (Grid emergency) is information related to a power failure or the like, and can be transmitted and received as a true or false signal, for example, as a Boolean. The information related to the power failure or the like is related to the reliability of components using energy.

If the specific component 30 recognizes the emergency information, it can be shut down immediately.

The grid reliability information is information about the amount of electricity supplied or the amount of electric power supplied or information about the quality of electric power. The grid reliability information may be transmitted or received as a true or false signal such as a Boolean, or an AC power The frequency of the component may be determined.

That is, when the frequency lower than the reference frequency of the AC power supplied to the component is detected, it is judged that the supplied electricity quantity is low (lack of supplied electricity quantity information), and when the frequency higher than the reference frequency of the AC power supply is detected, Electricity excess information).

In the case where the specific component recognizes that the electricity quantity is small in the network safety information or recognizes that the electricity quality is not good (insufficient supply electricity quantity information), as mentioned above, the specific component may output 0 Or remain stationary) to reduce output, maintain output, or increase output.

On the other hand, when the amount of electricity supply excess information is recognized, the specific component can be switched from an off state to an on state.

The energy increase information is information about a state in which the electricity consumed by the component consuming energy is smaller than the electricity generation amount and the surplus electricity is generated. For example, the energy increase information can be transmitted or received as a true or false signal like a Boolean.

When the specific component 30 recognizes the energy increase information, it can increase the output. For example, when the operation reservation is set, a component whose operation starts before a setting time or a component having a large output among a plurality of components can be driven first. Further, in the case of a refrigerator, it is possible to store the hot water by supercooling the output by increasing the output from the existing output, or by driving the heater in advance of the operation time of the heater in the case of the washing machine or the washing machine. Or if the particular component 30 recognizes an off-peak (for example, at the time of recognition).

The on-peak information, the energy reduction information, and the electricity shortage information among the energy-related information described above can be recognized as high-price information, which is understood to be relatively expensive.

On the other hand, off-peak information, energy increase information, and excess electricity supply information among the energy-related information can be regarded as low-price information that is relatively low in energy charge.

The information related to the upper and lower portions of the energy charge (high-cost or low-cost information) can be recognized as information for determining a power-saving driving mode of a specific component (for example, an energy consuming unit). That is, the user can recognize the time zone (region) according to the energy charge or the charge band (region) for determining the driving method of the component by using information about the up and down of the energy charge.

For example, when information related to energy is recognized as a boolean signal, the charge band for determining the time zone or the driving method of the component according to the energy charge may be recognized as two, Or if it is recognized as real time information, the time zone or the fare zone may be recognized as three or more.

On the other hand, the information related to the energy charge corresponding to at least the time can be recognized as information for determining the power saving drive method of the component. That is, the time zone (area) or the fare zone (area) can be recognized and distinguished by at least two or more using the information related to the energy charge. As described above, the time zone or the fare zone to be distinguished may be determined according to the type of information (boolean, multiple levels, real-time information) recognized.

In other words, two or more determination factors for driving the component can be distinguished and recognized using information related to the energy charge. The determination factors may include functions related to time and energy charges.

When the information related to the energy charge is leveled and recognized at two or more levels, the driving method may be determined according to the leveled information of the specific component.

On the other hand, when the information related to the recognized energy charge is not distinguished according to a specific criterion (for example, real-time charge information), information relating to the energy charge is compared with predetermined information, Can be determined.

Here, the predetermined information may be reference information (for example, a reference value) for distinguishing information related to the energy charge, and the comparison result may be related to whether or not the information related to the energy charge is equal to or greater than the reference value .

Specifically, each type of information related to the energy includes first unprocessed information 41, second information 42 that is information processed in the first information, And third information (43), which is information for performing a function of the component. That is, the first information is raw data, the second information is refined data, and the third information is a command for performing a function of a specific component.

And, energy related information is included in the signal and transmitted. At this time, at least one of the first to third information may be converted only the signal, but the content may be transmitted a plurality of times without being converted.

For example, as shown in the figure, a component receiving a signal including first information may simply convert a signal and transmit a new signal including first information to another component.

Therefore, in this embodiment, the conversion of the signal and the conversion of the information are described as different concepts. At this time, it can be easily understood that the signals are also converted when the first information is converted to the second information.

However, the third information may be transmitted a plurality of times in a state in which the contents are converted, or may be transmitted a plurality of times in a state in which signals are converted while maintaining the same contents.

In detail, when the first information is unprocessed electricity rate information, the second information may be processed electricity rate information. The processed electricity bill information is information or analytical information in which electric bill is divided into multiple levels. The third information is an instruction generated based on the second information.

The specific component may generate, transmit, or receive one or more of the first to third information. The first to third pieces of information are not necessarily sequentially transmitted and received. A plurality of third information may be transmitted or received sequentially or in parallel without first and second information. Alternatively, the first and third information may be transmitted or received together, the second and third information may be transmitted or received together, or the first and second information may be transmitted or received together.

In one example, when a particular component receives the first information, the particular component may transmit the second information, or may transmit the second information and the third information.

When a specific component receives only third information, the specific component can generate and transmit new third information.

On the other hand, in the relationship between two pieces of information, one piece of information is a message and the other piece of information is a response to a message. Accordingly, each component constituting the network system can transmit or receive a message, and can respond to a received message when receiving a message. Therefore, the transmission and correspondence of a message is a relative concept for individual components.

The message may comprise data (first information or second information) and / or instructions (third information).

The command (third information) includes at least one of a data storage command, a data generation command, a data processing command (including generating additional data), an additional command generation command, a further generated command transmission command, Command, and the like.

In this specification, responding to a received message may include storing data, processing data (including generating additional data), generating a new command, sending a newly created command, simply passing the received command (For example, a command to transmit a message to a user), operation, transmission of stored information, transmission of an acknowledge character or negative acknowledge character.

For example, if the message is first information, the component that received the first information may, in response thereto, generate the second information by processing the first information, or generate the second information and the new third information have.

The component that receives the message can respond to energy. Here, "correspondence" can be understood as a concept including an operation in which a component can perform its function. In one example, the home network 20 may receive messages and perform operations related to energy.

We describe in detail the correspondence (operation) of the energy of a component. The component may be, for example, an energy consuming part.

The energy consuming unit can be driven such that the energy charge when driven based on the recognition of the energy information is less than the energy charge driven without recognition of the energy information.

The component may include a plurality of modes driven for self-functioning. The plurality of modes may be driven in at least one of a first mode and a second mode in which the energy charge is saved relative to the first mode.

Here, the first mode may be a general mode, the second mode may be a power saving mode, and the first and second modes may be all power saving modes.

The general mode can be understood as a mode in which the self-function of the component is performed without recognizing the energy information. On the other hand, the power saving mode can be understood as a mode in which the self-function of the component is performed based on the recognition of the energy information, in order to save energy costs.

When the first mode is the power saving mode, the first mode is defined as a driving mode for saving energy bills, and the second mode is defined as a driving mode in which the energy rate is further saved than the first mode have.

On the other hand, at least a part of the driving method including at least the driving time and the course is recognized in association with the driving of the specific component (for example, the energy consuming part), and an unrecognized part can be generated , The recognized portion can be changed in a different manner.

For example, at least a part of the driving method can be recognized through setting of the user, control of the energy management unit, or self control of the energy consumption unit. And, when a specific driving method is further required for saving energy charges, the unrecognized driving method portion is newly generated, and the recognized portion can be changed in other ways for energy saving.

Of course, the process of generating the unrecognized portion may be omitted, and in this case, the process of changing the recognized portion in a different manner may be performed. On the other hand, the process of changing the recognized portion in a different manner may be omitted, and in this case, a process of newly generating the unrecognized portion may be performed.

The drive time may include a drive start time or a drive end time of the component. And, the course may include a driving period and an output of the component.

The manner in which it is created or changed may be in a manner recommended by a particular component to save energy bills. Here, the specific component may be an energy consuming unit (control unit) or an energy managing unit.

For example, if the recognized driving method is a specific driving time, the specific driving time may be changed to another time in order to reduce the energy charge, and a specific course may be created.

On the other hand, if the recognized driving method is a specific course, the specific course can be changed to another course and a specific time can be created to save energy costs.

According to this control, the time or the output value can be changed with respect to the output function of the component over time.

The manner in which it is created or the manner in which it is changed can be made within a set range. That is, in the course of recognizing at least a part of the driving method, within a predetermined criterion (for example, a restriction set by a user or set by an energy management unit or an energy consumption unit) May be generated or changed.

Therefore, within a range beyond the predetermined criterion, generation of the unrecognized portion or modification of the recognized portion is limited in other ways.

Other embodiments are suggested.

The recognized driving method may further include the charge information. That is, when the fare information is recognized, a portion related to the driving time or the course may be generated. The generated driving method can be recommended.

On the other hand, the correspondence of the components based on the information related to the up and down of the energy charge (high-cost or low-cost information), for example, output control for power saving drive can be performed. The output control may include output reduction (including output 0) or output increase.

According to the perception of information about the energy charge (on-peak or off-peak), the output is reduced or zeroed, maintained, or increased as described above.

If high-price information is recognized, the output can be zeroed or reduced. In detail, the output when the high-price information is recognized can be lower than the output when the low-price information is recognized. As described above, the reduction of the output can be determined in advance before starting the operation of the component, or can be changed when the high-price information is recognized after the start of operation.

If the output of a component is zeroed or reduced, the function that the component needs to perform may be lost rather than the normal case. Therefore, a countermeasure for preserving the lost function can be made.

For example, after the output of the component is reduced, the total operation time of the component may be increased or the output may be increased in at least one time period after the output reduction.

In other words, when the specific reference information related to the energy information is recognized in the section after the output of the component is adjusted, the output-adjusted correspondence can be released. Here, the term "section" may be defined based on the recognition time of the recognized high-price information.

The total operation time can be understood as a time at which a specific target value is reached in the course of performing the function of the component. For example, when the component is an electric appliance (a washing machine, a dryer, a cooking appliance, etc.) which is driven intermittently (driven by a specific course), the total operation time may be understood as a time until the course is completed.

On the other hand, when the component is an always-driven electric appliance (such as a refrigerator or a water purifier), it can be understood as a time to reach a set goal for performing a function of the component. For example, it may be a target temperature of the refrigerator, a target generated ice amount, or a target purified water amount.

And, the total operating time may be greater than the operating time set before the output reduction of the component, or may be increased over the operating time if the output is not reduced. However, even if the total operation time of the component is increased, the total energy charge generated through the component driving is controlled to be reduced as compared with the case where the output is not reduced.

Once high-price information is recognized, the output of the component can be increased.

However, even if the output increases at the time of recognizing the high-price information, the total output amount during the entire driving period of the specific component may be reduced or maintained to be less than the total output amount when the specific component operates at the normal output. Alternatively, even if the output increases at the time of recognizing the high-price information, the total consumed power or the total electricity charge during the entire driving period of the specific component is less than the total consumed power or the total battery charge when the specific component operates at the normal output Can be reduced.

If the low-price information is recognized, the output can be increased. For example, when the operation reservation is set, a component whose operation starts before a setting time or a component having a large output among a plurality of components can be driven first. Further, in the case of a refrigerator, it is possible to store the hot water by supercooling the output by increasing the output from the existing output, or by driving the heater in advance of the operation time of the heater in the case of the washing machine or the washing machine. Or when a particular component recognizes Low-price information (for example, when it recognizes it).

On the other hand, when a specific condition (additional condition) is generated even based on the information related to the upper and lower energy bills (high-cost or low-cost information), the correspondence of the components, for example, output control for power saving drive may be limited. That is, the output of the component can be maintained.

Here, "limitation" can be understood as being abandoned or the output control being performed is released.

The specific conditions include a case where the influence on the energy charge is small even if the output control of the component is not performed, or a case where it is necessary to prevent the function to be performed by the component from being degraded by controlling the output of the component.

Whether or not the influence on the energy charge is fine can be judged according to a certain criterion (information on the electric charge, the amount of electric power consumption or the operation time). The constant criterion may be a relative value or an absolute value.

In the case where the function to be performed by the component is degraded, for example, the component may be a defrost heater of the refrigerator.

In a case where the output is reduced in the high-price time interval and the output is increased in the low-price time interval, if the defrost heater is driven more frequently than the normal case (setting period), the temperature of the refrigerator storage room is raised In this case, the adjustment of the output can be restricted.

FIG. 4 is a diagram showing a communication structure of two components constituting the network system of the present invention, and FIG. 5 is a block diagram showing a detailed configuration of a communicator constituting communication means.

Referring to FIGS. 2, 4 and 5, a first component 61 and a second component 62 constituting the network system are connected to each other by a communication means 50, can do. And, the first component 61 and the second component 62 may communicate in one direction or in both directions.

When the two components 61 and 62 are in wired communication, the communication means may be a simple communication line or a power line communication means. Of course, the power line communication means may include a communicator (e.g., a modem or the like) connected to each of the two components.

When the two components 61 and 62 are in wireless communication, the communication means 50 includes a first communicator 51 connected to the first component 61, a second communicator 51 connected to the second component 62, And a second communicator 52 connected thereto. At this time, the first communicator and the second communicator perform wireless communication.

The first component 61 may be a component of the utility network 10 or may be a component of the home network 20.

The second component 62 may be one component of the utility network 10 or one component of the home network 20.

The first component 61 and the second component 62 may be of the same type or different types.

The component may be joined to the utility network 10 or the home network 20.

Specifically, a plurality of components, for example, the first component and the second component, may be assigned Addresses, which are necessary for communication between them and can be mapped into at least one group, respectively.

The address can be understood as a value converted from the unique code of the first component or the second component. That is, at least some of the components constituting the network may have an unchanging / unique code, and the code may be converted to an address for configuring the network.

In other words, product codes for at least some of the plurality of components that can constitute the first network and the second network can be converted into different network codes depending on the network being configured. have.

In one example, the product code may be a unique code determined at the time of production of the electrical product, or an installation code separately assigned for network registration. The product code can be converted to an ID for identifying a network to which the electrical product is to be registered.

The first network and the second network may be a network constituting the utility network 10 or a network constituting the home network 20. On the other hand, the first network may be a utility network 10, the second network may be a home network 20, the first network may be a home network 20, and the second network may be a utility network 10 .

The plurality of components constituting the network may include a first component and a second component for joining the first component to the network. In one example, the first component is an electrical product and the second component may be a server.

One of the first component and the second component may transmit a request signal to join the network and the other may transmit a permit signal.

That is, signals can be transmitted / received between the first component and the second component, and participation of the network can be determined according to the transmission time or the number of transmissions of the signal.

In one example, it is determined whether the first component transmits a test signal to the second component and a response signal is delivered from the second component. If the response signal is not transmitted, the test signal is transmitted again and it is judged whether or not the response signal is transmitted. This process is repeated. If the number of times of transmission of the test signal exceeds the preset number, it can be determined that the test signal is not participated in the network.

Meanwhile, the first component may transmit the test signal to the second component, and may be determined not to participate in the network unless a response signal is transmitted from the second component within the set time.

The first communicator 51 and the second communicator 52 may have the same structure. Hereinafter, the first communicator 51 and the second communicator 52 are collectively referred to as communicators 51 and 52, respectively.

The communicators 51 and 52 include a first communication part 511 for communication with the first component 61 and a second communication part 511 for communication with the second component 61. [ 512), a memory 513 for storing information received from the first component 61 and information received from the second component 62, a processor 516 for performing information processing, And a power supply 517 (power supply) for supplying power to the communicators 51 and 52.

In detail, the communication language (or mode) of the first communication unit 511 may be the same as or different from the communication language (or mode) of the second communication unit 512.

In the memory 513, two kinds of information received from the two components can be stored. Two types of information can be stored in a single sector or in separate sectors. In any case, an area where information received from the first component 61 is stored is referred to as a first memory 514, and an area where information received from the second component 62 is stored is referred to as a second memory 515 can do.

The processor 516 may generate the second information or generate the second information and the third information based on the information received from the component or another communicator.

In one example, when the communicator 51, 52 receives the first information, the communicator 51, 52 may process the data to generate the second information one by one or sequentially. Or when the communicator 51, 52 receives the first information, the communicator 51, 52 may process the data to generate the second information and the third information. When the communicator 51 or 52 receives the third information, the communicator 51 or 52 can generate new third information.

For example, if the second component is an energy consuming part (such as a component making up an appliance or a consumer product), the second communicator may generate an instruction to reduce energy consumption. When the second component is an energy generating unit, a distributing unit, or a storing unit, the second communicator 52 can generate a command related to an energy generation time, an amount of generated energy, an energy distribution timing, a distribution amount, have. In this case, the second communicator 52 serves as an energy management unit.

The second communicator 51 can receive the message either real time or periodically without a request to the first communicator 51 or as a response to the message request to the first communicator 51. [ Alternatively, when the second communicator 52 is turned on for the first time, the first communicator 51 requests the information to receive the message, and then, without requesting the information, the first communicator 51 Or periodically. ≪ / RTI >

The information received from the first communicator 51 is stored in the memory 513. And, as a response to the message, the second communicator 52 sends a message to the second component 62. [ At this time, the message transmitted to the second component 62 is related to new information different from the previously stored information in the memory 513, or to information generated by the processor 516. [

Or the second communicator 52 may transmit information of the first component stored in the memory to the first component, apart from transmitting information received at the first component.

Since the second communicator 52 stores the information of the second component 62, when receiving the component information request message from the first communicator 51, the second communicator 52 does not request the information to the second component 62 Since the component information stored in the memory 513 is directly transmitted to the first communicator 51, the communication load of the second component 62 can be reduced. That is, the second communicator 52 becomes a virtual component.

The second communicator 51 can receive the message either real time or periodically without a request to the first communicator 51 or as a response to the message request to the first communicator 51. [ Alternatively, when the second communicator 52 is turned on for the first time, the first communicator 51 requests the information to receive the message, and then, without requesting the information, the first communicator 51 Or periodically. ≪ / RTI >

At this time, the message transmitted to the second component 62 is related to new information different from the previously stored information in the memory 513, or to information generated by the processor 516. [ Alternatively, the information to be transmitted to the second component 62 may be information received from the first component and / or information received from the first component.

The second component 62 performs a function based on the received information or waits for function execution.

Meanwhile, the second component 62 performs information on the second component, such as component status information, component specific code, manufacturer, service name code, electricity usage, and the like, to the second communicator 52 Intermittently or periodically.

As described above, when the amount of electricity used is included in the information of the second component 62, it is possible to determine the amount of electricity used by the smart meter by comparing the information of the component information with the information of the smart meter, Can be performed.

The second communicator 52 then stores the component information in the memory 513 and sends an acknowledge character (ack) or negative acknowledge character (Nak) to the second component 62 as a response to the message do.

When the second communicator 52 receives the component information request message from the first communicator 51, the second communicator 52 transmits the information of the second component stored in the memory 513 as a response thereto. Or the second communicator 52 transmits component information stored in the memory 513 to the first communicator 51 in real time or periodically.

Since the second communicator 52 stores the information of the second component 62, when receiving the request message of the component information from the first communicator 51, the second communicator 52 transmits an information request to the second component 62 The information stored in the memory 513 is directly transmitted to the first communicator 51, so that the communication load of the second component 62 can be reduced. That is, the second communicator 52 becomes a virtual component.

Hereinafter, a third embodiment and a fourth embodiment of the present invention will be described. The embodiments are described mainly in terms of differences as compared with the previous embodiments, and the same parts are abbreviated to the description and the reference numerals of the previous embodiments.

FIG. 8 is a diagram showing a communication structure of components constituting a network system according to a third embodiment of the present invention, and FIG. 9 is a block diagram showing a detailed configuration of a first component in FIG.

8 and 9, the first component 70 may communicate with the second through fifth components 82, 83, 84, 85. Hereinafter, for example, the first component 70 is a central management unit (home server), the second and third components 82 and 83 are energy consuming units (household appliances) (Smart meter), and the fifth component 85 is a component of the utility network. And, the components can communicate with each other by communication means. Although the network system illustrated in FIG. 8 communicates with each component directly connected to the first component 70, when each of the components 82, 83, 84, and 85 connects and communicates with new components, The network system according to the present invention can be extended and operated.

The second component 82 and the third component 83 may be of the same type or different types and in the present embodiment the second component 82 and the third component 83 are different kinds of energy consuming deniers For example,

The first component 70 may simply forward information received from the fourth component 84 and / or the fifth component 85 to the second component 82 and / or the third component 83 , The received information can be processed and transmitted.

Also, the first component 70 may provide information received from the second component 82 and / or the third component 83 to the fourth component 84 and / or the fifth component 85, (The signal can be converted), and the received information can be processed and transmitted (the information is converted).

The first component 70 includes a communication means 760 for communicating with other components, a central manager 710 for managing the overall operation and / or information processing of the first component, API 720 (hereinafter referred to as " API ") serving as an interface between the means 760 and the central manager 710 (specifically application software).

The communication means 760 may include a first communication portion 762 for communicating with the second component 82 and the third component 83 and a second communication portion 762 for communicating with the fourth component 84. [ A second communication unit 764, and a third communication unit 766 for performing communication with the fifth component 85.

At this time, the first communication unit 762 and the second communication unit 764 can use different communication protocols. For example, the first communication unit 762 may use zigbee and the second communication unit 764 may use wi-fi. In this embodiment, the first communication unit 762 and the second communication unit 764, There is no restriction on the type of communication protocol or method used. The third communication unit 766 may use Internet communication as an example.

The API 720 includes a first API 722 and a second API 724 and a third API 726. The third API 726 is an interface between the central manager 710 and the third communication unit 766. The first API 722 and the second API 724 are interfaces between the first communication unit 762, And an interface between the second communication unit 764 and the central manager 710.

In addition, the first component 70 may be configured such that when the information to be transmitted / received between the API 720 and the communication unit 760 is information related to the operation of the energy consuming unit (household appliance) An interpreter 750 for interpreting information to be transmitted from the local manager 740 to the communication means 760 or information received from the communication means 760, . The information output from the interpreter is used to set an information value associated with each energy consuming unit and to obtain an information value.

The local manager 740 includes a memory (not shown) in which information relating to one or more energy consuming units is stored. Alternatively, the local manager 740 may be coupled to a memory in which information relating to one or more energy consuming units is stored. The information relating to each energy consuming part among the at least one energy consuming part may include information for operating the energy consuming part and information for controlling the energy consuming part. Further, it may further include software download information for operating each energy consuming unit, and information for remote control / monitoring.

For example, when a plurality of energy consumption parts include a washing machine, a refrigerator, and a cooking appliance, information related to each product is stored in the memory. The information related to the energy consuming unit stored by the local manager 740 may be changed in accordance with changes of components connected to the network system.

When a signal is transmitted from the API 720 to the local manager 740, information corresponding to the specific energy consuming unit is output. When there are a plurality of energy consuming parts, information on a plurality of energy consuming parts is stored in the memory. The interpreter 750 converts the information transmitted from the local manager 740 into a machine language for transmission to the energy consuming unit. The machine language may be a signal for inputting or obtaining operation information of the energy consuming part.

The information transfer process in the first component 70 will be described.

For example, the first component 70 may receive energy information (e.g., an energy reduction signal: first command) from the fourth component 45 via the second communication unit 764. The received energy information is transmitted to the central manager 710 through the second API 724. [ At this time, in the process of transmitting information between the second API 724 and the central manager 710, only the signal including the information is converted and the contents of the information are not converted.

Since the energy information is related to energy consumption reduction of the energy consuming unit, the central manager 710 transmits information (second command) related to the operation of the energy consuming unit to the API 720. For example, the central manager 710 transmits information necessary for turning off the power of the washing machine and the refrigerator.

Then, the information is transferred from the first API 722 to the local manager 740.

The local manager 740 transmits information (third command) for controlling the operation of each energy consuming unit to the interpreter 750 based on the information transmitted from the first API 722. For example, when the information transmitted from the first API 722 is information that targets energy consuming units of different types, the local manager 740 transmits information related to control of each energy consuming unit to the interpreter 750 do. At this time, the local manager 740 receives the second command and outputs the third command, so that the information input to the local manager 740 is converted and output by the local manager 740.

The interpreter 750 then converts the information sent from the local manager 740 into a machine language (signal). Then, the converted signal is transmitted to the energy consumption units (second and third components) of the target object via the first communication unit 762. Then, the energy consuming parts (second and third components) are finally turned off to reduce the energy.

In the above description, the first component receives information through the second communication unit. Otherwise, the first component receives the information through the third communication unit and outputs information related to the control of the energy consuming unit .

Meanwhile, the second component 82 and the third component 83 may transmit their operation information to the first component 70. Since the information transmitted from the second and third components 82 and 83 is information related to the operation of the energy consuming unit, the signal received by the first communication unit 762 is transmitted to the interpreter 750, the local manager 760, And is transmitted to the central manager 710 through the first API 722. [ In this information transfer process, the information related to the second and third components 82 and 83 is stored in the local manager 740. In this embodiment, since the local manager stores information related to the energy consuming unit, the local manager may be described as performing a virtual energy consuming unit abstraction model.

The central manager 710 may transmit the received information to the second communication units 764 and 766 and / or the third communication unit.

In summary of the operation of the first component, the information received via the communication means 760 is passed directly to the API 720, transformed (via the interpreter and the local manager) according to its type (or signal format) API 720. &lt; / RTI &gt;

The information transmitted from the central manager 710 may be transmitted to the direct communication means 760 or converted and transmitted to the communication means 760 depending on whether the energy consuming unit is related to the operation.

As another example, the local manager 740 may be configured to include an interpreter, and the information received via the communication means 760 is transmitted to the local manager, but the information is converted according to the contents of the transmitted information You can output it without outputting the information.

On the other hand, when the information transmitted to the API through the second communication unit 764 or the third communication unit 766 is raw data or refined data, the central manager 710 transmits an ON-peak time And transmits information (first command) to the API 720 to control the operation of the energy consuming unit in case of an on-peak time. Then, this information is converted through the local manager 740 (second command), and then transmitted to the energy consuming unit through the interpreter 750 and the first communication unit 762. Alternatively, the central manager 710 may transmit the electricity bill information to the first communication unit 762 through the second API 724 without determining the ON-peak. In this case, the information may or may not be converted. That is, when receiving the first information (raw data), the central manager can transmit first information or convert it into second information (refined data) and transmit the first information.

The first component 92 includes a communication unit 970 for communicating with other components, a central manager 920 for managing the entire operation and / or information transmission / reception process of the first component, An application programming interface (API) 930 serving as an interface between the communication means 970 and the central manager 920 (specifically, application software).

The communication unit 970 includes a first communication unit 972 for performing communication with the second to fourth components 94, 96 and 98 and a second communication unit 974 for performing Internet communication .

The API 930 includes a first API 932 and a second API 934. The second API 934 is an interface between the central manager 920 and the second communication unit 974 and the first API 930 is an interface between the first communication unit 972 and the central manager 920, Lt; / RTI &gt;

If the information to be transmitted / received between the first API 932 and the communication unit 970 is information related to the operation of the energy consuming unit (household appliance), the first component 92 corresponds to the energy consuming unit An interpreter 960 for interpreting information transmitted from the local manager 950 to the communication means 970 or information transmitted from the communication means 970, .

In this embodiment, the functions of the interpreter and the local manager are the same as those of the third embodiment, and a detailed description thereof will be omitted.

The information transfer process in the first component 92 will be described.

For example, the first component 92 may receive energy information (e.g., an energy reduction signal) from the fourth component 98 via the first communication unit 972. [ Alternatively, the second communication unit 974 may receive energy information from an external component connected to the Internet.

 The received energy information is transmitted directly to the first API 932 or the second API 934 and then to the central manager 920. Since the energy information is related to energy consumption reduction of the energy consuming unit, the central manager 920 transmits information related to the operation of the energy consuming unit to the first API 932. For example, the central manager 920 transmits information necessary for turning off the power of the washing machine and the refrigerator.

Then, the information is transferred from the first API 932 to the local manager 950.

The local manager 950 transmits information for controlling the operation of each energy consuming unit to the interpreter 960 based on the information transmitted from the first API 932. For example, when the information transmitted from the first API is information related to energy consuming units of different types, the local manager transmits information related to control of each energy consuming unit to the interpreter 960.

The interpreter 960 then converts the information sent from the local manager 950 into a machine language (signal). Then, the converted signal is transmitted to the energy consuming unit via the first communication unit 972, and the energy consuming unit is turned off to ultimately reduce energy.

Meanwhile, the second component 94 and the third component 96 may transmit their operation information to the first component 92. Since the information transmitted from the second and third components is information related to the operation of the energy consuming unit, the signal received by the first communication unit 972 is transmitted to the interpreter 960, the local manager 950, (932) to the central manager (920). In this information transfer process, information related to the second and third components 950 is stored in the local manager 950.

The central manager 920 can transmit the received information to the first communication unit 974. Then, the information of the second and third components 94 and 96 is transmitted to the fourth component 98.

In summary of the operation of the first component, the information received via the communication means 970 is passed directly to the API or transformed (via the interpreter and local manager) to API 930 according to its type (or signal format) Lt; / RTI &gt;

Conversely, the information transmitted from the central manager may be transferred to the direct communication means 970, or may be converted and communicated to the communication means 970, depending on whether it is related to the operation of the energy consuming unit.

Meanwhile, when the information transmitted to the API through the second communication unit is information related to the electric charge, the central manager determines whether the device is ON-peak time, and controls the operation of the energy consuming unit when the on- Information can be transmitted to the API. Then, this information is transmitted to the energy consuming unit through the local manager, the interpreter, and the first communication unit. In this case, it can be understood that the first component serves as an energy management unit.

Although it has been described above that the two energy consuming parts communicate with the first component, it is noted that there is no limitation on the number of energy consuming parts in communication with the first component.

In addition, although the first component is a home server, for example, the first component may be an energy manager. In this case, the fourth component in the above embodiments may be a central management unit, an energy management unit, a smart meter, or the like.

As another example, the first component may be a smart meter. In this case, in the above embodiments, the fourth component may be a central management unit, an energy management unit, or the like.

As another example, the first component may be the terminal component (e.g., a gateway).

As another example, the second and third components may be an energy generating unit, an energy storing unit, or the like, which constitute a home network. That is, the idea of the present invention is that at least one of the energy generating unit, the energy consuming unit, and the energy storing unit can communicate with the first component. In this case, the memory included in or connected to the local network may include information related to the energy generating unit (for example, information relating to the operation of the energy generating unit), information related to the energy storing unit Information related to the information (for example, the energy storage unit) can be stored.

In the above description, the first component is described as performing Internet communication, but may not perform Internet communication.

In the first embodiment, a single local manager is provided. Alternatively, a plurality of local managers may be provided. In this case, for example, the first local manager can process information on home appliances such as refrigerators and washing machines, and the second local manager can process information on display products such as televisions and monitors.

12 is a schematic diagram of a home network according to the present invention.

Referring to FIG. 12, the home network 20 according to the embodiment of the present invention includes an energy measuring unit 25 for measuring in real time power and / or electricity rates supplied from the utility network 10 to each home For example, a smart meter, the energy measurement unit 25, and an energy management unit 24 connected to and controlling the operation of the electric product.

On the other hand, the electricity rate of each household can be charged by the hourly rate, and the electricity rate per hour becomes high in the time interval in which the electric power consumption is rapidly increased, and the electricity rate per hour becomes low when the electric power consumption is relatively low .

The energy management unit 24 is connected to the energy management unit 24 through an internal network of the home and stores electrical products as an energy consuming unit 26 such as a refrigerator 110, a washing machine 120, an air conditioner 130, a dryer 140, 150) for bi-directional communication.

Communication in the home can be done through wired such as Zigbee, wifi, or a power line communication (PLC, Power line communication), and one household appliance can be connected to communicate with other household appliances.

13 and 14 are block diagrams showing the configuration of an electrical product according to an embodiment of the present invention.

13 and 14, a communication unit 210 is included in the electrical product 100 as an "energy consuming unit " according to the embodiment of the present invention. The electric appliance 100 may include the refrigerator 110, the washing machine 120, the air conditioner 130, the dryer 140, or the cooking appliance 150.

The communication unit 210 includes an energy measurement unit 25 for recognizing additional information other than energy information or energy information and an energy management unit 25 for managing (controlling) the operation of the electric product 100 according to the energy information or the additional information. (24). &Lt; / RTI &gt;

The energy measuring unit 25 and the energy managing unit 24 may be connected to each other to be able to communicate with each other. The communication unit 210 may be provided inside the electrical product 100 or may be detachably coupled to the electrical product 100.

The electronic product 100 includes an input unit 220 for inputting a predetermined command, a display unit 230 for displaying driving information of the electronic product 100 or information recognized from the communication unit 210, A memory unit 250 for storing received information, that is, energy information (for example, energy charge information) or additional information (for example, environmental information), and a control unit 200 for controlling these configurations.

The input unit 220 includes a power input unit 221 for inputting power to the electrical product 100, a mode selection unit 227 for selecting a driving mode of the electrical product 100, And a start input unit 229 for inputting the start of driving of the vehicle.

The mode selection unit 227 includes a normal mode selection unit and a power saving mode selection unit. The power saving mode selection unit may include a rate reduction mode for reducing the usage fee of the electric product 100 and an energy saving mode for reducing the usage energy of the electric product 100. [

The "drive mode" of the electrical product 100 is a drive mode determined depending on whether the electrical product 100 is driven based on energy information, and can be broadly divided into a general mode and a power saving mode . The general mode is a mode in which the electric appliance 100 is driven without recognizing energy information, and the power saving mode can be understood as being driven based on recognition of the energy information.

The power saving mode can be selected manually or automatically before the start of driving of the electric product 100. [ That is, the user may select the power saving mode by inputting the power saving mode selection unit, or the power saving mode may be automatically selected when the power of the electric product 100 is turned on. Of course, even if the power saving mode is automatically selected, the user may change the drive mode to the normal mode later.

In the power saving mode, a fare saving mode and an energy saving mode can be selectively provided. The user can select one of the above-described charge saving mode or energy saving mode and input the same. On the other hand, the fare saving mode or the energy saving mode may be set to the basic mode.

However, the energy saving mode may not be provided in the power saving mode, and the power saving mode itself may be configured to reduce the usage fee or energy used.

The driving method (information) of the electric product 100 can be understood as the minimum information necessary for driving the electric product 100. For example, the driving method may include driving time (period) or driving course of the electric product 100. Here, the "drive course" can be understood as a predetermined method for performing the functions of the component constituting the electric product 100 or the electric product 100 itself.

The driving method may be manually entered by the user or may be set in advance.

For example, even if the user does not separately input the driving method of the electric product 100, the basic driving method can be preset in the electric product 100. For example, when the electrical product 100 is a washing machine, a condition of "standard course, one hour" may be set by default when the washing machine is powered on. The user can perform washing by inputting only "OK button " In summary, the driving method of the electrical product 100 can be recognized manually or automatically.

In this way, in the state in which there is no recognition of the energy information, the driving method set by the user or automatically set for driving the electric product 100 is called "first driving method ". That is, the first driving method may be a driving method that is set manually or automatically according to the general mode.

In a state in which the low-cost information is received in the electric product 100, there is no problem that the electric product 100 is driven by the first driving method desired by the user. However, in a state where the high-cost information is received in the electric product 100, a problem may occur when the electric product 100 is driven by the first driving method.

For example, if the first driving method is a driving method using a high-output course in a situation where a current energy charge is very high, or a period in which a driving period of the electric product 100 and a period in which a high- In many cases there is a disadvantage in terms of usage fees.

Therefore, even if the first driving mode is manually or automatically recognized in the electric product 100, the information on whether the energy rate is high or low, that is, the information on whether the energy rate is high or low (high cost or low cost information) It can be changed to a second driving system in which the usage fee or energy is saved more than the driving system.

In summary, the electric product 100 may be driven in a manner such that the electricity usage amount or the electric charge is lower than the recognized driving method, that is, the "power saving driving method ". The power-saving driving method can be understood as a method in which the power saving is performed by changing the driving time or the driving course of the electric appliance itself or a component constituting the electric appliance. Hereinafter, the component constituting the electric product or the electric product is referred to as a "component ".

For example, the power saving driving method may include a method of adjusting (increasing, maintaining, or reducing) the output of the entire electric appliance or the component, or a method of shifting the driving period. Such a power saving driving method can be set in advance.

The electrical product (100) includes an operation unit (270) that is operated to perform the function of the electrical product (100). The operation unit 270 may be an electrical product 100 itself or a component thereof.

When the expensive information is recognized, the driving of the operation unit 270 can be controlled according to the power saving driving method.

For example, it can be recognized that a time period (hereinafter referred to as "high cost interval") where high-cost information is recognized is included in at least a part of a driving period of the component. If the high-cost period is included in at least a part of the driving period of the component, the power saving driving can be performed in the high-cost period or the entire driving period of the electric product or the component.

However, if a specific condition is recognized, the performance of the power saving drive may be limited.

The specific condition includes a case where performance of function or maintenance of the function of the component is restricted when the power saving drive is performed.

Here, the term "function" can be understood as a target function to be achieved by the electric product 100 or the component.

In one example, the target function may include a temperature value of a specific space. In particular, the temperature value of the specific space may include a preset storage room temperature of the refrigerator or a preset cooking room temperature of the cooking appliance.

The target function may include a temperature value of the circulating medium. In detail, the temperature value of the circulating medium may include a set washing water temperature of the washing machine or a set hot air temperature of the dryer.

The target function may include a set storage amount holding function of the power storage device.

On the other hand, the target function may include a set rotation speed of the motor or the compressor, a set calorific value of the heater, or a set storage capacity maintenance function of the battery.

Whether the function execution (maintenance) of the component is restricted or not can be determined depending on whether the state information value of the component is outside the setting range. The state information value may include a specific state value of the component described above, that is, a temperature value, a charge amount, a rotational speed, or a calorific value.

And, the setting range can be understood as a minimum limit range for maintaining the function of the component. In other words, the setting range may be at least the range that the component must satisfy to perform its original function.

Therefore, when the status information value does not satisfy the setting range, it can be restricted that the component performs its own function. In this case, the component can perform driving according to the normal mode (hereinafter referred to as general driving) without performing driving according to the power saving mode (hereinafter, power saving driving).

As described above, the general drive can be understood to be driven in accordance with the drive method (drive course or drive time) set in the electric product 100 without being based on the energy information.

 Whether the function maintenance of the component is restricted may be determined before or during the power saving operation of the component is performed. Hereinafter, a control method according to a determination timing of whether or not to maintain the function of the component will be described.

14 is a flowchart illustrating a method of controlling an electrical product according to an embodiment of the present invention. The present embodiment shows a control method in the case where it is determined whether or not the power saving drive is performed before the power saving drive of the component is performed.

The component is powered on and a predetermined driving method is recognized. The driving method may be manually or automatically recognized, and may include driving course or driving period information. Energy information or additional information may be received in the component (S11).

From the received energy information or additional information, it is recognized whether a high cost section is included in the driving period of the component (S12).

If the high-cost period is included in the driving period of the component, the driving method according to the power saving mode is recognized, and it can be determined whether or not the component performs power saving driving (S13).

To this end, it is recognized whether the expected information (hereinafter referred to as "power saving drive prediction information") when the component performs the power saving drive is outside the set range. That is, when the power saving operation is performed, it is recognized whether the state information value of the component is outside the set range.

The power saving drive prediction information may include information about a driving period of the component, a redundant size of the high-cost period, or a function deterioration of the component during power saving operation.

As described above, the status information value may be a predetermined value (temperature value, storage amount, rotation number, calorific value, etc.) that can be measured or sensed in the process of driving the component. In addition, the setting range may be a minimum limit range for maintaining the function of the component (S14).

If the state information value is out of the setting range, it can be determined that the function maintenance of the component is restricted during the power saving driving process (S15).

In this case, the component does not perform the power saving drive, and can perform the general drive that is not based on the energy charge. That is, if the power saving driving is not performed, the component can be driven while maintaining the setting output or the setting driving period (S16).

On the other hand, if the state information value is within the setting range, it can be determined that the function maintenance of the component is not restricted during the power saving drive process.

Thus, the component can perform power saving driving. In one example, the component can adjust (increase, maintain, or reduce) the output and shift the drive period. Here, the driving period may include driving or delay driving in advance (S17).

15 is a flowchart illustrating a method of controlling an electrical product according to another embodiment of the present invention. The present embodiment shows a control method in the case where it is determined whether or not the power saving drive is released while the power saving drive of the component is being performed.

The component is powered on and a predetermined driving method is recognized. The driving method may be a driving method according to the power saving mode.

Then, the component can start the power saving operation according to the recognized driving method (S11). Energy information or additional information may be received in the component (S22).

From the received energy information or additional information, it is recognized whether a high-cost interval is included in the driving period of the component (S23).

If the high cost section is included in the driving period of the component, it is determined whether or not the power saving operation of the component is continued (S24).

To this end, it is recognized whether or not the power saving drive information of the component is outside the set range. That is, when the power saving operation is continuously performed, whether the state information value of the component is outside the set range is recognized.

The power saving drive information may include information about a driving period of the component and a redundant size of the high-cost period or whether the component is degraded during the power saving operation (S25).

If the state information value is out of the setting range, it may be determined that the function maintenance of the component is restricted during the power saving driving process (S26).

Therefore, the component can stop the power saving operation, and can then perform a general drive that is not based on the energy charge. That is, when the power saving driving is not performed, the component can be driven while maintaining the setting output or the setting driving period (S27).

On the other hand, if the state information value is within the setting range, it can be determined that the function maintenance of the component is not restricted during the power saving drive process.

Therefore, the component can continue the power saving drive. In one example, the component can adjust (increase, maintain, or reduce) the output and shift the drive period. Here, the driving period may include driving or delay driving in advance (S28).

Hereinafter, another embodiment of the present invention will be described. The present embodiment differs from the previous embodiment in that the power saving operation is manually released or is not performed. Therefore, the difference will be mainly described, and the description of the previous embodiment and the reference numerals .

16 is a block diagram showing a configuration of an electrical product according to another embodiment of the present invention.

Referring to FIG. 16, the electrical product 100 according to the present embodiment includes a power saving release input unit 228 that can be input to perform the power saving drive of the electrical product 100 or to release (stop) the power saving drive.

The power saving release input unit 228 may be configured as an input unit separate from the power input unit 221, the mode selection unit 227, and the start input unit 229, and may be configured as the same device as at least one of the input units 221, As shown in Fig.

When the input of the power saving release input unit 228 is required, the power saving release input unit 228 may be activated or flickered for easy viewing by the user. The power saving release input unit 228 may be provided with an input button or a screen touch method.

From the received energy information or additional information, it is recognized whether or not the high-cost interval is included in the driving period of the component (S32).

If the high-cost period is included in the driving period of the component, the driving mode according to the power saving mode can be recognized, and a manual selection mode for whether or not the component performs power saving driving can be started (S33).

The power saving drive prediction information of the component and the setting range can be displayed to be comparable. The user can confirm the displayed information (S34).

It is recognized whether or not the power saving drive prediction information of the component is out of the set range. If the power saving drive prediction information is out of the setting range, it may be recognized that the function maintenance of the component is restricted when the component performs power saving operation (S36).

On the other hand, if the power saving drive prediction information is within the setting range, it can be recognized that the performance of the component is maintained even if the component performs power saving operation (S37).

As described above, the power saving drive prediction information, that is, the state information value may be a predetermined value (temperature value, storage amount, rotation number, calorific value, etc.) that can be measured or sensed in the process of driving the component. And, the setting range may be a minimum limit range for maintaining the function of the component.

It is recognized whether or not the power saving release input section 228 is input. The power saving release input unit 228 may be activated in a state in which the power saving drive prediction information of the component and the setting range are displayed to be comparable. The user can determine whether to select the activated power saving release input section 228 (S38).

If the power saving release input unit 228 is input, the user is not aware of the power saving operation of the component, and the power saving operation is not performed (S39).

On the other hand, if the power saving release input unit 228 is not input, the component performs power saving drive. Whether or not the power saving release input unit 228 has been input may be determined depending on whether or not the power saving release input unit 228 is operated within the set time. If the power saving release input unit 228 is not input within the set time, the power saving drive may be performed (S40).

As described above, when the high-cost period is included in the component driving period, the user can set whether or not to perform the power saving drive, thereby increasing the usability and reducing the energy charge.

18 is a flowchart showing a control method of an electrical product according to another embodiment of the present invention. This embodiment shows a control method in the case where it is determined whether or not the function maintenance is restricted while the power saving operation of the component is being performed.

The component is powered on and a predetermined driving method is recognized. The driving method may be a driving method according to the power saving mode.

Then, the component can start the power saving operation according to the recognized driving method (S51). Energy information or additional information may be received in the component (S52).

From the received energy information, it is recognized whether a high cost section is included in the driving period of the component (S53).

If the high-cost period is included in the driving period of the component, a manual selection mode may be initiated to determine whether the component performs power saving operation (S54).

The power saving driving information of the component and the setting range can be displayed in a comparable manner. The user can confirm the displayed information (S55).

It is recognized whether the power saving drive information of the component is out of the set range (S56). If the power saving drive information is out of the setting range, it can be recognized that the function maintenance of the component is restricted when the component performs power saving operation (S57).

On the other hand, if the power saving drive information is within the setting range, it can be recognized that the performance of the component is maintained even if the component performs power saving operation (S58).

As described above, the power saving drive information, that is, the status information value may be a predetermined value (temperature value, storage amount, rotation number, calorific value, etc.) that can be measured or sensed in the process of driving the component. And, the setting range may be a minimum limit range for maintaining the function of the component.

As described above, the general mode is understood as a method in which the driving method is determined based on energy information, and the component is driven (S60).

The stored driving information may be displayed on the display unit 230 before the power saving driving of the component is stopped. The user can change driving information of the component based on the contents displayed on the display unit 230. [

Of course, the range in which the driving information can be changed is within the setting range, and the user can guide the display unit 230 to change the driving information to a value within the setting range (S61).

The component may be driven with modified drive information or drive information corresponding to the general mode (S62).

On the other hand, if the power saving release input unit 228 is not input, the component continues the power saving drive.
