Description

Network System

The present invention relates to a network system.

The supplier simply supplied energy sources such as electricity, water and gas, and the consumer simply used the supplied energy sources. Therefore, effective management in terms of energy production, distribution, or energy use has been difficult to carry out.

In other words, energy is a radial structure that is distributed from energy suppliers toward multiple demand sources, that is, spreads from the center to the periphery, and is characterized by unidirectional supplier center, not consumer center.

The price information for electricity was not only available in real time, but only limitedly through the power exchange, and since the price system is also a de facto fixed price system, incentives such as incentives to consumers through price changes cannot be used. There was a problem.

In order to solve this problem, there have been a lot of efforts in recent years to implement a horizontal, cooperative, and distributed network that effectively manages energy and enables interaction between consumers and suppliers.

SUMMARY OF THE INVENTION An object of the present invention is to provide a network system that can effectively manage an energy source and stop communication when communication between a plurality of components is abnormal.

According to one aspect, a network system includes: a first component that operates in conjunction with energy; When operating in relation to energy, a second component is included that can communicate with the first component by means of a communication means, and communication between the first component and the second component can be interrupted in either component.

According to the proposed invention, since a communication state between a plurality of components is abnormal or manual or automatic communication between components can be manually stopped, it is possible to prevent abnormal operation of a specific component and to improve user convenience. There is an advantage to meet.

In addition, since a specific component can recognize energy information and additional information by communication between a plurality of components, the energy source can be efficiently produced, used, distributed, stored, and the like, thereby enabling efficient management of the energy source. do.

3 is a block diagram showing a process of transferring information on a network system of the present invention. FIG. 4 is a graph illustrating a form of an electric charge. FIG. 4A is a graph showing time of use (TOU) information and critical peak pattern (CPP) information, and FIG. 4B is a RTP ( This graph shows real time pattern information.

Referring to FIG. 3, in the network system of the present invention, a specific component C may receive information related to energy (hereinafter, “energy information”) by communication means. In addition, the specific component (C) may be additional information (environmental information, program update information, time information, operation or status information of each component (breakdown, etc.), in addition to the energy information by the communication means, consumer habit information using the energy consumption unit, etc. ) Can be received further.

The environmental information may include carbon dioxide emissions, carbon dioxide concentration in the air, temperature, humidity, rainfall, rainfall or the like, solar radiation, air volume, and the like.

In another aspect, the information is internal information, such as information related to each component (operation or status information of each component (such as failure), energy usage information of the energy consumer, consumer habit information using the energy consumer, etc.), and other information. Phosphorus can be classified into external information (energy information, environment information, program update information, time information).

At this time, the information may be received from other components. In other words, the received information includes at least energy information.

The specific component may be one component constituting the utility network 10 or one component constituting the home network 20.

As described above, the energy information I may be one of information such as electricity, water, and gas.

For example, information related to electricity includes time-based pricing, energy curtailment, grid emergency, grid reliability, energy generation amount, and operational priority. (operation priority), energy consumption amount (Amount). In this embodiment, the fee associated with the energy source may be referred to as an energy fee.

In other words, energy-related information may be classified into charge information (energy charge) and non-charge information (energy reduction, emergency situation, network safety, generation amount, operation priority, energy consumption amount, etc.).

Such information may be classified into schedule information previously generated based on previous information and real time information that changes in real time. The schedule information and the real time information may be distinguished by predicting information after the current time (future).

The energy information I may be classified into 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. The energy information I may change with time.

Referring to FIG. 4A, according to the TOU information, data is gradually changed in time. According to the CPP information, the data changes step by step or in real time with time, and emphasis is displayed at a specific time point. That is, in the case of the CPP pattern, the general fee is lower than that of the TOU pattern, but the charge at a specific time point is significantly higher than that in the TOU pattern.

Referring to FIG. 4B, according to the RTP information, data changes in real time with time.

Meanwhile, the energy information I may be transmitted and received with a true or false signal, such as a Boolean on a network system, or actual price information may be transmitted or received, or may be leveled and transmitted. Hereinafter, information related to electricity will be described by way of example.

When the specific component C receives a true or false signal, such as a Boolean, any one signal is recognized as an on-peak signal (recognition of information related to energy consumption or reduction of energy bill). The other signal may be recognized as an off-peak signal.

In contrast, a particular component may recognize information about at least one driving including an electric charge, and the specific component compares the recognized information value with the reference information value to compare the on-peak and off-peak ( off-peak).

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

In this case, the information value related to the driving may be at least one of an electric charge, a power amount, a change rate of the electric charge, a change rate of the power amount, an average value of the electric charge, and an average value of the electric power. The reference information value may be at least one of an average value, an average value of minimum and maximum values of power information during a predetermined section, and a reference rate of change of power information (eg, slope of power consumption per unit time) during the predetermined section.

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

When the specific component (for example, the energy consumption unit) recognizes an on-peak (for example, a recognition time point), the output may be zero (stopped or stopped) and the output may be reduced. 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 starting the operation.

And, if a particular component recognizes an off peak, the output can be restored or increased as needed. That is, when a specific component that recognizes an on peak recognizes an off peak, the output may be restored to a previous state or increased more than the previous output.

At this time, even when the specific component recovers the output or increases the output after recognizing the off-peak, the total power consumption and / or the total electricity bill for the entire operating time of the specific component is reduced.

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

The schedule standard may be set in real time or may be set in advance. The schedule criterion may be set in the utility network or in a home network (input from a consumer direct input, an energy manager, a central manager, etc.).

Alternatively, when the specific component recognizes an on-peak (eg, a recognition time), the output may be increased. However, even when the output is increased when the on-peak is recognized, the total output amount during the entire driving period of the specific component may be reduced or maintained than the total output amount when the specific component operates at the normal output.

Or, even if the output is increased when the on-peak is recognized, the total power consumption or total electric charge for the entire operating period of a particular component is the total power consumption or total power when the specific component operates at normal output. It can be lower than the electricity bill.

When the specific component recognizes an off-peak (for example, a recognition time), the output may be increased. For example, when an operation reservation is set, a specific component may start driving before a set time, or a component having a larger output among a plurality of components may be driven first.

In addition, in the case of a refrigerator, the output may be supercooled by increasing the output, or in the case of a washing machine or a washing machine, the hot water may be stored in the hot water tank by driving the heater in advance of the scheduled operation time of the heater. This is to reduce the electricity bill by operating in the off-peak in advance to operate in the on-peak to come later.

Alternatively, when a specific component recognizes an off-peak (eg, a recognition time), power storage may be performed.

In the present invention, the specific component (for example, the energy consumption unit) may maintain, reduce or increase the output. Thus, a particular component can include a power changing component. Since the power can be defined by current and voltage, the power variable component can include a current regulator and / or a voltage regulator. For example, the power variable component may be operated according to a command generated from an energy management unit.

Meanwhile, the energy curtailment information is information related to a mode in which a component is stopped or a low electric charge is used. In other words, the energy reduction information is information related to the reduction of energy consumption or energy bill. The energy saving information may be transmitted and received with a true or false signal, for example, as a Boolean on a network system. That is, a turn off signal or a lower power signal may be transmitted and received.

When the specific component recognizes the energy saving information, as described above, the output can be zeroed (if the stop or stop state is recognized) or the output can be reduced (if the lower power signal is recognized). have.

The grid emergency information is information related to a power failure and the like, and may be transmitted / received as a true or false signal such as Boolean. Information related to the power outage is related to the reliability of the component using energy.

When the specific component recognizes the emergency information, it may be immediately shut down.

When the specific component receives the emergency information as the schedule information, the specific component may increase the output before the arrival of the emergency time point to perform the same operation as the off-peak operation of the specific component described above. . In addition, the specific component may be shut down at an emergency time.

The grid reliability information is information about the high and low supply electricity or information on the quality of electricity, and is transmitted / received by a true or false signal, such as a Boolean, or supplied to a component (for example, a home appliance). The component may determine the frequency of the AC power.

That is, when an under frequency is detected (recognized) below the reference frequency of the AC power supplied to the component, the amount of supply electricity is determined to be low, and when the frequency higher than the reference frequency of the AC power is detected (recognized), the supply electricity is This can be judged by many. That is, the frequency lower than the reference frequency (underfrequency) corresponds to information related to the reduction of energy consumption or energy bill.

When the specific component recognizes that the amount of electricity in the network safety information is low or the information that the electrical quality is not good, as mentioned above, the specific component to output 0 (stop or stop) in some cases, You can reduce the output, maintain the output, or increase the output.

The excessive amount of generated electricity information is information on a state in which excess electricity is generated since the amount of electricity consumed by the component consuming less energy than the amount of generated electricity may be transmitted / received as a true or false signal, for example, a Boolean.

When the specific component recognizes excessive power generation information (for example, when grid overfrequency is recognized or when over energy signal is recognized), the output may be increased. For example, when an operation reservation is set, a specific component may start driving before a set time, or a component having a larger output among a plurality of components may be driven first. In addition, in the case of the refrigerator to increase the output than the existing output supercooled, or in the case of a washing machine or a washing machine, the hot water can be stored by driving the heater in advance than the scheduled time of operation of the heater.

On the other hand, each kind of information related to the energy, specifically, the unprocessed first information (I1), the second information (second information (I2)) that is processed information from the first information, and the specific The information may be divided into third information I3 which is information for performing a function of a 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.

The energy information is included in the signal and transmitted. In this case, one or more of the first to third information may be transmitted only a plurality of times without converting only the signal.

For example, as shown in the figure, any component that receives a signal including the first information I1 may only convert a signal and transmit a new signal including the first information I1 to another component.

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

However, the third information may be delivered a plurality of times in the state where the contents are converted or in a state where only the signal is converted while maintaining the same contents.

In detail, when the first information is raw electricity price information, the second information may be processed electricity price information. The processed electric charge information is information or analysis information in which electric charges are divided into multiple levels. The third information is a command generated based on the first information or the second information.

The particular component may generate, transmit or receive one or more of the first to third information. The first to third information are not necessarily sequentially transmitted and received.

For example, only a plurality of third information may be transmitted or received sequentially or in parallel without the 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.

For example, when a specific component receives the first information, the specific component may transmit the second information, the second information and the third information, or may transmit only the third information.

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

Meanwhile, in the relationship between the two informations, one information is a message and the other information is a response to the message. Accordingly, each component constituting the present network system may transmit or receive a message, and when the message is received, may correspond to the received message. Thus, the transmission of messages and their corresponding responses is a relative concept for individual components.

The message may include data (first information or second information) and / or command (third information).

The command (third information) includes a data storage command, a data generating command, a data processing command (including generating additional data), a generating command of an additional command, a sending command of an additional generated command, and a received command. Commands and the like.

In the present specification, corresponding to a received message means storing data, processing data (including generating additional data), generating a new command, sending a newly generated command, and simply passing the received command to another component. Command can be generated together), operation, transmission of stored information, transmission of acknowledgment character or negative acknowledgment character.

For example, when the message is the first information, the component that has received the first information corresponds to this to generate the second information by processing the first information, generate the second information, and generate new third information, Only third information can be generated.

In detail, when the energy management unit 24 receives the first information (internal information and / or external information), the energy management unit 24 generates second information and / or third information to establish the home network. It may transmit to one or more components (for example, energy consumption unit) constituting. The energy consumption unit 26 may operate according to the third information received from the energy management unit 24.

The first component 31 may receive information from the utility network 10 or one or more components constituting the utility network 10, and transmit or process the received information to process the second to fourth components. Can be sent to (32, 34).

9 is a block diagram of specific components of a second embodiment of the network system of the present invention.

Referring to FIG. 9, a specific component constituting the network system of the present invention (hereinafter, referred to as a first component) may communicate with another component (hereinafter referred to as a second component). The configuration and functions thereof related to the first component 70 described in the present embodiment may be equally applied to the second component.

The first component 70 includes a control unit 71, an input unit 72, a communication unit 73, a display unit 75, and a memory unit 76. In the present embodiment, the functions of the control unit 71, the display unit 75, and the memory unit 76 are the same as those described with reference to FIG. 8, and thus a detailed description thereof will be omitted.

The communication means 73 of the present embodiment may include a communication setting button 74. The function of the communication setting button 74 is the same as described in FIG. When the communication setting button 74 is included in the communication means 73, the communication setting button 74 may be exposed to the outside of the first component so that a user may operate the communication setting button 74. have. When the communication setting button 74 is exposed to the outside of the first component, the communication setting button 73 is set to operate only when the communication setting button 73 is pressed for a predetermined time or more so as to prevent inadvertent cancellation of communication or interruption of communication. Can be.

On the contrary, the communication setting button 74 may be covered by a cover or the like to prevent exposure to the outside.

FIG. 10 is a view for explaining a method of releasing communication of a plurality of specific components in the third embodiment of the network system of the present invention.

In the present embodiment, it is characterized in that the interruption of communication or the cancellation of the communication is automatically performed.

Referring to FIG. 10, a plurality of components (eg, a first component and a second component) perform communication to transmit or receive information (S1).

In the process of communicating between the plurality of components, one or more components determine whether the communication state is abnormal (S2). When the communication state is an abnormal state, when the communication means of at least one component is an abnormal state, when the communication means of a specific component recognizes an abnormal signal, when the specific component can not recognize the signal for a predetermined time, When a specific component operates based on the received information, but the operation of the specific component is abnormal (for example, when the high power energy consumption unit continuously operates during the on-peak period, except for the high-power energy consumption unit during the on-peak period). And only when the output is set to be reduced or stopped.

If the communication state is an abnormal state, one or more of the plurality of components (for example, a component that recognizes that the communication state is an abnormal state) stops the communication (network leave) (S3). Alternatively, a component recognizing that the communication state is abnormal among the plurality of components may transmit specific message information for checking the communication state before stopping the communication. In addition, the component that has received the specific information may transmit a confirmation message (abnormal status confirmation message) for this. Then, the component recognizing that the communication state is abnormal is to stop the communication.

In addition, communication stop information is displayed on the display unit of at least one component (S4). Even when communication of a plurality of components is interrupted, a specific component may operate in a smart mode as described in FIG. 8.

After a certain time elapses after the communication is stopped, the plurality of components may release the communication stop. At this time, if the communication state becomes abnormal even after canceling the communication interruption, the communication is stopped again.
