Currently, there are many tools used to make life more comfortable. At home, air conditioning for indoor air conditioning, refrigerators for storing food, television and radio providing entertainment, and computers are used to make life convenient. The factory is in need of manpower shortage, Most mechanization is proceeding for work.

These various devices, including home appliances, consume electricity as their energy source, and power plants are being built to generate electrical energy.

Recently, the consumption of energy is increasing day by day, and the existing thermal power resources are becoming depleted. As a result, interest in the development of new energy is increased and interest in energy consumption is increasing.

In the summer, when energy consumption is soaring, it produces a certain amount of energy in order to meet the demand for electric energy. However, as the energy consumption is increasing day by day, there is a problem in energy supply and demand. However, studies are under way to reduce energy consumption in the current situation where the facilities such as power plants can not be increased indefinitely.

Therefore, it is necessary to measure the amount of power consumed in the building, to limit the amount of power consumed by controlling the operation rate of the equipment to be operated, or to increase the energy consumption. It is not responding.

On the other hand, rather than simply limiting and managing the energy consumed in a single assumed building, it is necessary to organically connect the energy generating place and the consuming place, such as the power generating plant, through the communication network to generate energy in accordance with the required amount , A method of inducing the consumption of energy to change as the generated energy and the consumed energy are increased or decreased is proposed.

FIG. 2 shows an embodiment of an energy management system according to the present invention, and FIG. 3 shows another embodiment of an energy management system according to the present invention.

Referring to FIG. 2, the energy supplied by the energy supplying company 500 is introduced into the energy consuming home along the energy transmission line 510 and used in the various energy using devices 301, 302, and 303.

A smart meter (or energy management device (EMS)) 100 is installed in the energy consuming home.

The smart meter (or energy management device (EMS)) 100 is an electronic meter that detects energy usage information, such as energy usage, through the energy using devices 301, 302, and 303.

The smart meter 100 includes at least a meter reading unit 191, a storage unit 192, a measuring unit 193, and a predicting unit 194. The smart meter (or the energy management apparatus (EMS)

One or more of the meter reading unit 191, the storage unit 192, the measuring unit 193, and the predicting unit 194 in the smart meter (or the energy management apparatus (EMS) 100) Lt; / RTI > may be configured to perform its role while communicating with the element.

The smart meter (or the energy management device (EMS)) 100 further includes a control unit 195 for controlling the energy consuming devices 301, 302, and 303 of energy consumption according to the prediction result in the prediction unit 194 .

Referring to FIG. 3, the role of the storage unit 192 and the prediction unit 194 may be configured to be performed by the central server 600.

The central server 600 can transmit energy price information through a variety of communication networks such as a wireless mesh, a power line communication network, and the Internet network.

The energy use devices 301, 302, and 303 are devices that consume energy supplied from the energy supply company 400. [ As a concrete example, when the energy is electricity, the energy-using device is a device that operates using electricity such as a refrigerator, a TV set, a heating device, a cooling device, and a lighting device.

FIG. 4 shows an example in which a smart meter (or an energy management device (EMS)) 100 is installed in a home, which is a major demand source of the smart grid.

Here, the electric power charge can be charged based on the hourly charge rate, and the electric power charge becomes high when the electric power consumption is rapidly increased, or the electric power charge becomes low per hour when the electric power consumption is relatively low. .

Meanwhile, the home may include an auxiliary power source 400, that is, an autonomous power generation facility such as a photovoltaic power generation apparatus, and a battery capable of storing electric power generated in the self power generation facility. In addition to the above battery, the fuel cell can also serve as an auxiliary power source. Here, the auxiliary power source serves to supply power to the home without receiving power from an external power source such as a power company.

FIG. 5 shows an example of configuring a home network using a smart meter (or an energy management device (EMS)) 100 in the home.

Also, the smart meter (or the energy management device (EMS)) 100 may be connected to an access point (AP) to form a network with a user's portable device, and may be connected to each other through the network.

As a wireless local area communication method used for constructing such a home network, Bluetooth, Zigbee, and wireless LAN may be used.

Bluetooth is a wireless PAN (Personal Area Network) connection technology that is currently installed in the largest number of mobile communication terminals in the world. It is an audio communication service such as a wireless handsfree, a stereo music streaming, a one phone, And data communication services such as message exchange. Bluetooth is increasingly used because it allows free wireless communication among various devices within a relatively narrow area (10 to 100m) at low cost and low power consumption.

ZigBee communication has been widely used for control of home appliances such as lighting devices, air conditioners, TV receivers, and the like, which are present in a home or office network. ZigBee communication is also expected to be widely used in building a home network because it has advantages in that it implements wireless device control with low cost and low power.

Wireless LAN is a communication technology based on IEEE 802.11, and is currently the most widely used.

As such, the home network connects household appliances in the home, such as a refrigerator, a washing machine, a dryer, an air conditioner, a home appliance such as a TV or a cooking appliance, or the like. Therefore, it is configured to be able to control all digital household appliances such as a computer, a digital television receiver, a digital video player, and a refrigerator / heater by connecting to a network built in the home via the Internet or a telephone line, both inside and outside the home network.

As such, the smart meter (or energy management device (EMS)) 100 may form a plurality of networks and may be connected to each network.

In addition, the smart meter (or the energy management device (EMS)) 100 may be connected to a current electricity consumption state, for example, an electric consumption state of each device (i.e., an on / (Temperature, humidity) and the like can be provided to the outside through the Internet.

Figure 6 illustrates an example in which a smart meter (or an energy management device (EMS)) 100 is connected to a cloud service in accordance with an embodiment of the present invention.

Recently, cloud services are becoming more popular in order to make various information more convenient and available anywhere. In particular, as the use of smart devices such as smart phones is increasing, the demand of users who want to access various information and data by accessing the cloud service from anywhere is increasing. Accordingly, there are many cases where a client that can receive various services from a cloud server is installed in various devices.

As shown in Figure 6, according to one embodiment of the present invention, a smart meter (or an energy management device (EMS)) 100 accesses a manufacturer / energy provider cloud service to exchange various states of the smart meter . In addition, the manufacturer cloud service enables exchange of various information about the smart meter (or the energy management device (EMS)) 100. For example, the manufacturer / energy provider cloud service may also receive information from the smart meter (or energy management device (EMS)) 100, such as billing information, energy consumption, etc., Energy consumption pattern, and to provide the statistical information to the user's terminal from anywhere outside the user's request. Meanwhile, the manufacturer cloud service provides information on firmware information and operation status from the smart meter, stores the firmware information, and provides the firmware information to the user terminal when requesting the user. In addition, the manufacturer cloud service receives information on the charge energy consumption and the like from the smart meter (or the energy management device (EMS)) 100, and statistically and processes the information to generate various statistical information such as an energy consumption pattern And can provide it to the terminal of the user anywhere on the user's request. In addition, the manufacturer cloud service may receive various information such as billing information and power generation amount from the energy supplier, and may transmit the information to the user.

A smart meter (or an energy management device (EMS)) 100 according to an embodiment of the present invention may include a processor 110, a communication unit 120, and a functional unit 130.

The communication unit 120 may include a physical layer, a medium access control (MAC) layer, and a network layer.

The function unit 130 may include a core function unit for performing a core function of the smart meter (or the energy management apparatus (EMS)) 100. As described above, the core function includes a meter reading unit 192 for sensing energy consumption, a measuring unit 193 for measuring energy consumption, and a control unit 195 for controlling the amount of energy used. do. As described above, the core function may further include a storage unit 192 for storing various information, a predicting unit 194 for predicting the amount of energy used, and a predicting unit 194 for predicting the variation in the fee.

Meanwhile, the management function unit manages the operation state of the smart meter (or the energy management device (EMS)) 100, and the like.

The management function enables the smart meter (or the energy management device (EMS)) 100 to provide a variety of information that can be provided by the cloud service. Here, various information that can be provided by the smart meter (or the energy management device (EMS)) 100 may include not only information on the operation state, abnormality, etc., but also information on the current electricity consumption state, , on / off status and consumption amount in case of on) and information on the inside and outside environment (temperature, humidity) and the like.

Thus, according to one embodiment of the present invention, a smart meter (or Energy Management Device (EMS)) 100 provides various information to a manufacturer / energy provider cloud service, Information of the smart meter (or the energy management device (EMS)) 100 installed in the home can be conveniently used anywhere.

Figure 7 illustrates an example in which a smart meter (or an energy management device (EMS)) 100 is connected to a cloud service in accordance with another embodiment of the present invention.

First, the manufacturer / energy provider cloud service has a disadvantage in that it is weak in support of additional services for reproducing various information due to its somewhat closed nature. In addition, the manufacturer's cloud service provides a specialized service for a smart meter (or an energy management device (EMS)) 100 manufactured by a particular manufacturer, and thus has a disadvantage that compatibility with other equipment may deteriorate. In particular, when a user wants to use information on a plurality of smart meters (or an energy management device (EMS)) 100, the user has to access the cloud service of each manufacturer. For example, when a user manages energy usage in his / her home as well as in a parent's home or a child's home, if the smart meter (or energy management device (EMS) It is troublesome to access cloud services of different manufacturers.

To this end, a smart meter (or an energy management device (EMS)) 100 according to another embodiment of the present invention may include a manufacturer / energy provider cloud service as well as a third party Party cloud services or social network services.

Thus, there is a need for a smart meter (or energy management device (EMS)) 100 to be able to dynamically interoperate in exchanging information by accessing multiple cloud services or social network services.

In simple terms, a client module for multiple cloud services or social network services may be installed in a smart meter (or an energy management device (EMS)) 100, Processing load of the processor 110 is increased. In order to do this, it is necessary to install a high-performance processor 110, which causes an increase in the unit price of the smart meter (or the energy management device (EMS)) 100, The power consumption of the device (EMS) 100 is also increased. As the power consumption increases, the smart meter (or the energy management system (EMS)) 100 inherently deviates from the essence of the apparatus for measuring the power consumption of other energy consuming apparatuses and reducing the consumption amount thereof, The problem has to be serious.

In addition, separately installing client modules for multiple cloud services or social network services in a smart meter (or energy management device (EMS)) 100 is another problem. For example, multiple cloud services or social network services are expanding their capabilities for their own specialized services, making it difficult to keep pace with them.

Accordingly, a smart meter (or an energy management device (EMS)) 100 according to another embodiment of the present invention may have a cloud service / social network service charge unit 135 and the cloud service / ) Is a cloud service broker that makes a plug-in client for each server to dynamically respond to multiple cloud servers, accepts the plug-ins, and connects the system with the appropriate cloud server. , And an abstracted service layer that provides a consistent interface.

 First, the plug-in performs a minimum function in a cloud-specific client. That is, the plug-in only plays a role of processing a unique protocol (OpenAPI) used by the servers when connecting with external cloud servers. Such a plug-in can be simply and dynamically generated by a script or a configuration file.

The cloud service broker plays a role of accepting the plug-ins and processes various information according to the API of the external cloud server. That is, the cloud service broker extracts only a part of information from various information according to the API of the external cloud server, and delivers the extracted information to the plug-in. The various information may be transmitted from the Abstracted Service layer.

The Abstracted Service layer receives various kinds of information from the core function unit and processes and displays different functions for each cloud server as a consistent interface.

FIG. 8 shows an example in which the smart meter (or energy management device (EMS)) 100 shown in FIG. 7 uses various cloud services.

8, a smart meter (or an energy management device (EMS)) 100 may be connected to various cloud services and a user may access the smart meter (or energy management Device (EMS)) 100 through various cloud services and social network services.

For example, if the smart meter (or the energy management device (EMS)) 100 is provided with the power failure forecast from the illustrated energy supply company server 500 from the manufacturer / energy provider cloud service, Such as push service, SMS service, e-mail service, etc., via the cloud service or the social network service to the user's terminal 200.

As another example, if the smart meter (or the energy management device (EMS)) 100 is provided with price information from the illustrated energy supply company server 500 from the manufacturer / energy provider cloud service, the price information is transmitted to the third party cloud Service, and the third party cloud service may provide information on the usage pattern to the user terminal 200 by calculating an optimal usage pattern (for example, a power usage control pattern in a peak time zone). When the user confirms the usage pattern through the terminal 200 and informs the user of the agreement, the third party cloud service transmits the usage pattern to the smart meter (or the energy management device (EMS)) 100 . The smart meter (or energy management device (EMS)) 100 may then control various energy consuming devices according to the usage pattern (e.g., to adjust the cooling and heating temperature in advance of peak time, or the washing machine to operate after peak hours Control).

FIG. 9 is a flowchart showing an example in which a smart meter (or an energy management device (EMS)) 100 connects to a plurality of services, and FIG. 10 shows an example in which a user uses a plurality of services according to FIG.

9, the smart meter (or the energy management device (EMS)) 100 accesses a first service server among a plurality of services and obtains the same day power charge information and peak time zone information (S110).

Then, the smart meter (or the energy management device (EMS)) 100 transmits the received information to a second service server (e.g., a social network service) among a plurality of services (S120). At this time, it is assumed that the smart meter (or the energy management device (EMS)) 100 has its own account in the first service server (e.g., a social network service). It is assumed that the account is set to a relationship between a user's account and a friend relationship or a close relationship. In this case, due to the transmission of the information, the information is opened to the second service server in the account of the smart meter. In this case, the user can access the second service server through his or her own portable device, when necessary, using his / her account to browse the information initiated by the account of the smart meter. Or, due to the transmission of the various information, the second service server may push the information to the account of the user associated with the account of the smart meter.

For example, as shown in FIG. 10, when the smart meter (or the energy management device (EMS)) 100 starts power price information of the peak time period of its own account, the smart meter Is displayed.

9, the smart meter (or the energy management device (EMS)) 100 may receive a third service request from the user (S130). For example, as shown in S130 of FIG. 10, the user may transmit a message to the smart meter (or the energy management device (EMS)) 100 via the second service server to analyze how much the fare will be today have.

Then, the smart meter (or the energy management device (EMS)) 100 may transmit the charge information, the time zone information, and the existing usage pattern information to the third service server so as to request the information on the current day charge (S140).

If the smart meter (or the energy management device (EMS)) 100 receives the information on the estimated price for the day from the third service server (S150), the smart meter can transmit it to the second service server and inform the user again .

Meanwhile, as shown in FIG. 9, the smart meter (or the energy management device (EMS)) 100 may receive a fourth service request from the user (S160). For example, as shown in S160 of FIG. 10, a message to suggest a better usage pattern may be transmitted to the smart meter (or energy management device (EMS)) 100 via the second service server.

Then, the smart meter (or the energy management device (EMS)) 100 may request an optimized usage pattern for the fourth service server as shown in FIG. 9 (S170).

When the smart meter (or the energy management apparatus (EMS)) 100 receives the information on the optimized usage pattern from the fourth service server (S180), the information about the optimized usage pattern is transmitted to the second service server And informs the user again (S190). For example, as shown in the figure, a message suggesting that the air conditioner is operated from 3:00 may be transmitted to the user.

At this time, if the user agrees with the proposed pattern, the smart meter (or the energy management device (EMS)) 100 can control power usage according to the information.

FIG. 11 is a diagram showing a configuration in which a smart meter (or an energy management apparatus (EMS)) 100 and a digital broadcast receiver 300 are fused according to another embodiment of the present invention.

Referring to FIG. 11, the control unit 195 and the cloud service / social network service charge unit 135 in the smart meter (or the energy management apparatus (EMS) 100) 300). 6 and 7, the smart meter 100 includes a processor 110, a communication unit 120, and a function unit 130. The function unit 130 includes a meter reading unit 192, The control unit 195 and the cloud service / social network service charge unit 135 are integrated into the digital broadcast receiver 300. In this case,

Specifically, each function and operation will be described as follows.

The smart meter (or energy management device (EMS)) 100 receives smart grid information from an energy supply company 500. Then, the received smart grid information is transmitted to the digital broadcast receiver 300. The smart grid information is power information collected in the smart grid network.
