The present invention relates to a power-termination energy network system capable of collecting power consumption information for power termination of a light switch (LS) and a power outlet (PO) in a household (home) zone, and changing and controlling power consumption patterns.

In particular, the present invention is a tree-structured energy tree network in which a plurality of power terminations for a household (home) area are used as leaf nodes, and an energy gateway and a switch sensing gateway are used as roots and branches, respectively. After setting, the energy tree network configuration identification and power consumption information are collected through tree-based uplink scanning, and power consumption state control is performed for power termination through tree-based downlink command transmission. It relates to a power-termination energy network system that performs power use management at the power-termination level.

In recent years, as the standard of living has improved in general, the number of electrical appliances that people use in their daily lives has increased, as well as a trend toward high-end and large-capacity. As a natural result, the power consumption of each household (home) is continuously increasing, and problems such as power production cost, pollutant emission, and power supply and demand have been raised. Therefore, there is a need for a technology for effectively monitoring and managing power usage.

In general, the amount of electricity used in each household (home) is metered and billed by an watt-hour meter.For example, an analog watt-hour meter or a digital watt-hour meter is used to check the power consumption of each household and charge the amount used according to the result. Each household can check whether their electricity consumption is currently at an appropriate level or excessive by referring to the monthly billing amount. If it is judged to be excessive, they feel the need to reduce power consumption, and each person takes their own savings plan.

However, such conventional power management is only a degree of calculating and charging the total amount of power in units of generations, and there is a problem in that it is not possible to inform what type of power use occurs inside the household. As a result, it is difficult for individual households to determine whether their own power consumption is appropriate or excessive, and even if they decide to reduce power consumption, it is difficult to determine where on earth they should start with their hands because they do not know the cause of the increase in power consumption in detail. .

The present invention is an energy network system for power terminals that enables power management for a household (home) area to be performed at a power termination level. To this end, referring to FIG. 1, the power termination energy network system configures an energy tree network based on a plurality of power terminations 100. At this time, the plurality of power terminations 100 form leaf nodes of the energy tree network. In addition, in order to manage these power terminations 100, the switching sensing gateway 200 is arranged for each area to form a branch of the energy tree network, and the energy gateway 300 is used for overall power management for the household area. It forms the root of the energy tree network.

Through this, information on where on earth power is consumed a lot in the house can be grasped in great detail and provided to the user. As users know the cause of the increase in power consumption in detail, it is possible to effectively reduce unnecessary electricity consumption by individual efforts.

Hereinafter, the concepts and roles of the power termination 100, the switch sensing gateway 200, and the energy gateway 300 constituting the energy tree network in the present invention will be described in detail with reference to [Figs. 1] to [5]. .

First, the power terminals 100 are configured at the ends that consume electrical energy within a household, and a plurality of light switches (LS) 101 and power outlets installed in the household area It is composed of (Power Outlet; PO) (102, 103). Referring to Fig. 3, electricity is supplied from the outside to the inside of the household area via the switchboard 1, and the electricity supply line in the household area is generally a light electric line 2 and an outlet electric line 3. It is done separately. At this time, the electric light line 2 supplies power to a plurality of light switches LS, and the outlet electric line 3 supplies electric power to a plurality of power outlets PO.

In relation to the plurality of power terminals 100 in which electricity is supplied in this way, in the present invention, an energy tree network is preferably configured through a separate communication line (eg, CAN communication, Ethernet communication, RF communication).

In the present invention, the power termination 100 forms leaf nodes in an energy tree network operated for power use management in a household area, and is actually treated as a basic unit that consumes electric energy. In the present invention, the power termination 100 is equipped with a configuration (eg, a power gauge) that detects a terminal power consumption amount related to itself in real time and a configuration that identifies its own power consumption state. In addition, the power termination 100 has a configuration to identify the termination attribute information for itself. For example, some of the plurality of power terminations 100 identify information about whether a node uses constant power for itself or a node that needs to manage standby power. In addition, the power termination 100 transmits information related to each of itself (termination power consumption amount, power consumption state and its change event, termination attribute information) to the switch sensing gateway 200 corresponding to its parent node.

Next, the switch-sensing gateway 200 is a component in charge of the size of a room. The household area has a spatial structure such as a room, a living room, a kitchen, and a toilet, and the switch sensing gateway 200 is in charge of a plurality of internal areas corresponding to the spatial structure of the household area. The switch sensing gateway 200 forms a branch in the energy tree network, and connects a plurality of power terminations 100 installed in the internal area space in charge of itself as child nodes, and the energy gateway 300 Is connected to the parent node. Based on this connection, it plays a role of relaying information for each area connecting the power termination 100 installed in the corresponding internal area and the energy gateway 300 that manages the household area.

Information of the power termination 100 may be effectively collected by the energy gateway 300 by relaying information for each area of the switch sensing gateway 200. The energy gateway 300 can identify the topology of the energy tree network and the properties of individual leaf nodes by collecting and relaying attribute information from a plurality of power terminals 100 by a plurality of switch sensing gateways 200. do. In addition, the end power consumption and state change events detected by each power end 100 are collected and relayed periodically or at that time by the switch sensing gateway 200, so that the energy gateway 300 is in the power consumption state of the energy tree network. It is possible to grasp in real time and appropriately perform power state change control if necessary.

In addition, the energy gateway 300 can manage a plurality of power terminals 100 in units of internal zones such as a room, a living room, a kitchen, a toilet, etc. by relaying information for each area of the switch sensing gateway 200.

In this regard, referring to [Fig. 3], the light switch (LS) 101 is connected to each switch sensing gateway 202 one by one. This is taken into account that it is common to have one light switch (LS) installed in the interior areas such as rooms, living rooms, kitchens, and toilets. On the other hand, multiple power outlets (POs) 102 and 103 may be connected to one switch sensing gateway 202. It is considered that more than one power outlet (PO) is usually installed for each internal area.

In addition, the switch sensing gateway 200 may be provided with a sensor that senses information on an internal area in charge of each. For example, it is equipped with sensors such as temperature, humidity, motion detection, and air quality for the area. The sensing information thus obtained may be collected by the energy gateway 300 and transmitted to the user's smartphone through a broadband network, for example, so that the user may check it.

In addition, since the information handled by the switch sensing gateway 200 is not only of the nature of which privacy must be protected, but also of the nature that no one outside can change it without permission, an encryption module, such as an AES128 module, is used to prevent hacking. It is preferably provided in (200).

In order to perform the above functions, the switch sensing gateway 200 according to the present invention includes a sensing information identification unit 210, an upper node communication unit 220, a switch sensing control unit 230, a communication encryption processing unit 240, and a zone termination. It is configured to include a management unit 250 and a lower node communication unit 260.

Next, the energy gateway 300 is a configuration in charge of the size of a household area, for example, a house. Basically, one energy gateway 300 is provided and used for each household area. In the case of a large mansion, a plurality of energy gateways 300 may be provided. For example, it is possible to install the energy gateway 300 for each floor, and in order to show such flexibility, two energy gateways 301 and 302 are shown in FIG. 1.

The energy gateway 300 plays a role of a root in the energy tree network. That is, one energy gateway 300 defines one energy tree network. Therefore, in the case of a large mansion, if a plurality of energy gateways 300 are disposed, a plurality of energy tree networks are operated in the mansion. The energy gateway 300 connects the plurality of switch sensing gateways 200 as child nodes, and manages power use for a plurality of power terminals 100 in the energy tree network based on information relay for each area provided by them. .

To this end, the energy gateway 300 relays and receives the terminating power consumption and terminating attribute information for the power terminating 100 in charge of each of the plurality of switch sensing gateways 200 that are its child nodes. By adopting such a tree-structured information flow, information generated from a plurality of power terminals 100 existing in the household area is quickly and efficiently collected by the energy gateway 300. The energy gateway 300 identifies and manages topology and node arrangement information for an energy tree network that it is responsible for based on the relayed data. In other words, it is possible to identify information on how many internal areas exist in the energy tree network in which the user is responsible, and which power termination 100 is arranged in each of the internal areas.

Then, the energy gateway 300 calculates the area power consumption for each of the plurality of internal zones by collecting a plurality of terminal power consumptions relayed and transmitted, and calculates the household power consumption amount for the household area. In other words, it monitors in real time the terminal power consumption, area power consumption, and household power consumption for the energy tree network that it is in charge of. Using this information, it is possible to manage the power consumption status of a plurality of power terminals 100 existing in the household area.

For example, it is desirable to generate an error event because if it is identified that power consumption is stopped for a power termination (eg 102) that is identified as a node using constant power, something may have occurred. The power termination 102 may have failed or the outlet electric line 3 may have a failure. In addition, when power consumption for a power termination (eg, 103) identified as a node that manages standby power falls below a preset threshold, the provision of power may be temporarily stopped. It can also warn of possible fires in the event of overconsumption of power far exceeding the existing usage for a specific power end (eg 102) or a specific interior area.

In addition, the energy gateway 300 provides information on terminal power consumption, area power consumption, household power consumption, and preferably sensing information collected for a corresponding household area to an external power management service server through a broadband network. This externally provided information is preferably transmitted to the user's smartphone so that the user can check it, and more preferably, it is possible to change and control the power consumption state at the terminal level in response to the user's operation of the smartphone.

In addition, since the information handled by the energy gateway 300 is not only of a nature that must be protected by privacy, but also of a nature that must not be changed by someone outside without permission, an encryption module, such as an AES128 module, is used to prevent hacking. ) Is preferably provided.

In order to perform the above functions, the energy gateway 300 according to the present invention includes: 310: generation end management unit 310, 320: external server communication unit 320, 330: generation power management unit 330, 340: communication encryption processing unit (340), 350: power consumption management unit 350, 360: is configured to include a tree node communication unit (360).

Hereinafter, an information transmission structure between the power end 100, the switch sensing gateway 200, and the energy gateway 300 constituting the energy tree network in the present invention will be described with reference to FIGS. 1 and 2.

In the energy tree network, information transmission takes place in the form of messages, and these messages are divided into information messages and control messages. In Fig. 2, the first body part is a part (ID) indicating which power termination 100 the corresponding message is related to.

That is, the'LS/PO' field is a field indicating whether the corresponding power end 100 is a light switch (LS) or a power outlet (PO), and the'Position ID' field indicates that the corresponding power end 100 is the corresponding internal area. It is a field that tells where the location is within, and the'Name' field is a field that stores a text string that allows humans to distinguish what the corresponding power end 100 is, and the'Info/Ctrl' field Is a field indicating whether the message is an information message or a control message.

If the'Info/Ctrl' field of the first body part is a value corresponding to Info (eg 0), this message is an information message, and the second body part of the message is encoded according to the Info format in the second line of [FIG. 2]. Here, the'standby power/constant power' field is a field indicating whether the corresponding power termination 100 is a device that needs to manage standby power or a device that uses constant power, and the'Status' field is a corresponding power It is a field indicating the power consumption status (ON, OFF, Standby, Slow, Express, High Performance) for the terminal 100, and the'power consumption' field is a field indicating the amount of power currently being consumed by the corresponding power terminal 100. .

Conversely, if the'Info/Ctrl' field of the first body is a value corresponding to Ctrl (eg 1), this message is a control message, and the second body of the message is encoded according to the Ctrl format in the third line of [Fig. 2]. will be. Here, the'status control command (CtrlCmd)' field represents a command for the energy gateway 300 to change and set the power consumption state for a specific power end 100, and the'event identification information (Event ID)' field Denotes information for notifying the power termination 100 to the switch sensing gateway 200 and the energy gateway 300 of what has happened to it.

In the present invention, a plurality of power terminations 100 constituting an energy tree network, a plurality of switch sensing gateways 200, and energy using an information message and a control message having the above field format Information is transferred between the gateways 300 as described later.

[Fig. 6] shows that the energy gateway 300 collects information on the energy tree network through bottom-up tree-based scanning in the power termination energy network system according to the present invention, and performs a power consumption change control operation for the power termination 100 It is a diagram showing an example of the process.

In FIG. 6, information collection of the energy tree network is performed in a manner in which an information message is transmitted from the power termination 100 to the energy gateway 300 in a bottom-up manner. On the other hand, the power consumption change control operation is performed in a manner in which a control message is transmitted from the energy gateway 300 to a specific power end 100 in a top-down manner.

First, the power termination 100 includes location information (Position ID), unique identification information (Unique ID), and type information (LS/PO) as unique information, and at least one of them is standby power management information related to itself. And constant power management information. In addition, the power termination 100 may detect the power consumption status information (Status) and the terminal power consumption amount (PwCons) related to itself in real time. Here, standby power management information, constant power management information, and power consumption status information are referred to as'attribute information of a terminal' for convenience in this specification.

When these power terminations 100 receive the first scan request message (ScanReq1) from the switch sensing gateway 200, which is their parent node in the energy tree network, their power consumption status information (Status) and terminal power Consumption amount (PwCons) and unique information (Position ID, Unique ID, LS/PO) are transmitted as a first scan response message (ScanReply1) to the switch sensing gateway 200, which is its parent node. Each switch sensing gateway 200 receives a response and transmits a first scan response message (ScanReply1) from all the power terminals 100 connected to it, and through this, the switch sensing gateway 200 There are two power terminations 100 and it is possible to identify what properties they have.

In addition, when the power termination 100 receives a termination control message (TermCtrl) from the switch sensing gateway 200, which is its parent node in the energy tree network, the power termination 100 responds to the state control command (CtrlCmd) encoded in the message. Switching control of the power consumption state of

Next, the switch sensing gateway 200 includes, as unique information, area information (Region ID), which is information for identifying an internal area that it is responsible for. The switch sensing gateway 200 has at least one power terminal 100 arranged in its own area in the energy tree network as a child node, and the terminal attribute information and terminal power consumption transmitted from them are transferred to the energy gateway 300. We relay it. In addition, the termination control message (TermCtrl) from the energy gateway 300 is relayed from the energy tree network to the corresponding power termination 100, which is its child node.

When the switch sensing gateway 200 receives the second scan request message (ScanReq2) from the energy gateway 300, the switch sensing gateway 200 responds and transmits its own information (Region ID) as a second scan response message (ScanReply2) in response thereto. All switch sensing gateways 200 of the energy tree network transmit a second scan response message (ScanReply2), and through this, the energy gateway 300 has several switch sensing gateways 200 in its own energy tree network. It identifies whether it exists, that is, how many interior zones exist in the household zone.

Then, the switch sensing gateway 200 receives a status query message (Inquiry) from the energy gateway 300. The switch sensing gateway 200 transmits a first scan request message (ScanReq1) to its child node in the energy tree network in order to obtain information to respond to this status query message (Inquiry). A first scan response message (ScanReply1) is received from one or more power terminations 100, which are child nodes. Through this, the switch sensing gateway 200 can specifically identify the power termination 100 existing in the internal area it is responsible for. The first scan response message (ScanReply1) includes power consumption status information (Status), terminal power consumption (PwCons), and unique information (Position ID, Unique ID, LS/PO) for each power termination 100. , The switch sensing gateway 200 collects these first scan response messages (ScanReply1) and lists the power consumption status information (Status) and unique information (Position ID, Unique ID, LS/PO) of the power terminals that responded to it. (PO List) is transmitted to the energy gateway 300 as a Q&A message (Report).

Next, the energy gateway 300 is provided with a route identifier (Root ID) for distinguishing and identifying the household area it is responsible for as unique information. The energy gateway 300 identifies the topology of the energy tree network and compares the terminal power consumption and the terminal attribute information for a plurality of power terminals 100 belonging to the energy tree network, and as a result, a preset power control condition is established. A power control operation for changing the power consumption state is performed for the corresponding power termination 100.

The energy gateway 300 transmits a second scan request message (ScanReq2) from the energy tree network to its child node and receives a second scan response message (ScanReply2) from each of the switch sensing gateways 200 as a response thereto. Through this, it is possible to identify how many switch sensing gateways 200 exist in the energy tree network and what their region IDs are.

Subsequently, the energy gateway 300 transmits a status inquiry message (Inquiry) to each of these switch sensing gateways 200, and receives a Q&A message (Report) as a response thereto. By analyzing these Q&A messages (Report), the energy gateway 300 has several power terminals 100 connected to each of the switch sensing gateways 200, and what is their unique information and the power consumption status. ) And terminal power consumption (PwCons) can be identified. Through the above process, the energy gateway 300 identifies the topology of the energy tree network and the states of a plurality of power terminations 100 belonging thereto. The identified information is preferably managed in the form of a database.

At this time, the process of identifying the topology of the energy tree network and the process of identifying the power consumption state and the terminal power consumption may be configured to be performed separately or may be configured to be performed at once.

Then, the energy gateway 300 compares and analyzes the terminal power consumption and the terminal attribute information for a plurality of power terminals 100 belonging to the energy tree network, and as a result, the corresponding power termination 100 in which a preset power control condition is established. ) To change the power consumption state. To this end, a state control command (CtrlCmd) corresponding to the power control condition is generated, and a termination control message (TermCtrl) including the state control command (CtrlCmd) is transmitted based on the node arrangement information of the energy tree network. It transmits (100) to a specific switch sensing gateway 200 taking as a child node. For example, in [Fig. 3], in order to perform the power consumption state change control for the power termination 103, a termination control message (TermCtrl) is transmitted to the switch sensing gateway 202 taking the power termination 103 as a child node. do.

As an embodiment, the energy gateway 300 compares the end power consumption amount and the constant power management information of the end attribute information for a plurality of power end 100 to determine the end power consumption amount of the power end 100, which is the target of constant power management. When it is less than a preset first threshold, a failure for the corresponding power termination 100 can be identified. If the power consumption abnormally decreases in an outlet port, such as a refrigerator, that must be provided with constant power, it is determined that something has occurred.

As another embodiment, the energy gateway 300 compares the terminal power consumption amount and the standby power management information of the terminal attribute information for a plurality of power terminals 100, and thus the terminal power consumption amount of the power terminal 100, which is the target of total electromotive force management, is When it is less than the second preset threshold, a specific state control command (CtrlCmd) to switch off the corresponding power termination 100 is generated, and the corresponding power termination 100 is used as a child node based on the node arrangement information of the energy tree network. It may be configured to transmit to the switch sensing gateway 200, thereby reducing power consumption for household areas. In recent years, it takes into account the fact that power waste due to standby power has become serious.

7 is a diagram illustrating a process in which the energy gateway 300 performs power consumption change control in response to a power consumption state change event of the power termination 100 in the power termination energy network system according to the present invention.

First, the power termination 100 may detect or identify a power consumption state change event in relation to itself. For example, switching on/off, entering standby mode, exiting from standby mode to active mode, or increasing power consumption above or below a certain threshold, each power shutdown ( 100) may detect an event in which the power consumption state is changed according to a classification criterion set in advance in relation to itself.

In this case, the power termination 100 acquires a terminal power consumption amount (PwCons) associated with it using, for example, a power gauge, and its terminal power consumption amount from the energy tree network to its parent node, the switch sensing gateway 200. Sends an event notification message (EventTrgg) including information (PwCons). At this time, it is preferable that the event notification message (EventTrgg) be configured in the format of a control message, and the terminal power consumption information (PwCons) is inserted by dividing and defining a part of the field of the control message, or a separate information message (Info Message) can be configured to be delivered.

Next, when the switch sensing gateway 200 receives an event notification message (EventTrgg) from the power termination 100, which is its child node, in the energy tree network, the switch sensing gateway 200 relays it to the energy gateway 300.

The energy gateway 300 receives an event notification message (EventTrgg) by the relay operation of the switch sensing gateway 200, from which a specific power consumption state change event has occurred for the power termination 100. And, thereby, it is identified that the terminal power consumption (PwCons) has changed.

In this case, the energy gateway 300 updates the terminal power consumption amount, the area power consumption amount, and the household power consumption amount for the energy tree network based on the contents of the event notification message (EventTrgg). This updated information can be viewed on an external service server and on the user's smartphone through a broadband network.

Then, preferably, as described above with reference to [Fig. 6], the terminal power consumption amount and the terminal attribute information are compared and analyzed, and as a result, when a preset power control condition is satisfied, the power It performs a power control operation that changes the consumption state. To this end, a termination control message (TermCtrl) including a state control command (CtrlCmd) corresponding to the power control operation is transmitted to the corresponding power termination 100 via the switch sensing gateway 200.

Meanwhile, the present invention may be implemented in the form of a computer-readable code on a computer-readable nonvolatile recording medium. Various types of storage devices exist as such non-volatile recording media, such as hard disks, SSDs, CD-ROMs, NAS, magnetic tapes, web disks, cloud disks, etc., and codes are distributed and stored in multiple storage devices connected through a network. It can be implemented and executed form. In addition, the present invention may be implemented in the form of a computer program stored in a medium in order to execute a specific procedure by being combined with hardware.
