The present invention relates to a method and apparatus for providing information on energy usage through a femto network and controlling the energy usage.

In general, the meter is to generate the metering data by measuring the amount of energy used in the field using mechanical and electronic measuring means, which is difficult to calculate by manpower, such as electricity, gas, water, hot water, and heat. Various forms have been developed and applied according to the type of energy used or the use and scale of the meter.

The amount of metering data measured through the meter was counted according to a manual detection system in which a person visits a local area where the meter is installed and confirms it, and delivers the checked meter data to a metering institution. When the meter reading data amount is aggregated through the manual detection system, the meter reading authority notifies each user of the energy usage fee calculated based on the aggregated meter reading data amount. The passive detection system operated as described above has a high cost burden such as time and labor costs, and has a problem in that accuracy is reduced due to being performed by a person.

In order to solve the problem of the passive detection system, an automatic detection system through a digital weighing meter has been introduced. In the automatic detection system, the meter reading data measured through the digital meter is transmitted to a server of a meter reading institution located at a remote location through internet communication or power line communication using a general telephone line or an Internet dedicated line. Then, the meter reading authority converts the amount of the metering data of each of the local areas collected through the server into a usage fee, and issues a fee bill to the user of the local areas. The automatic detection system as described above has the advantage of enabling the energy reading data of the meter reading engine to be quickly and accurately captured at a lower cost.

The present invention provides a user with information on the energy usage of a local area serviced by the FAP using a femto base station (hereinafter referred to as a 'FAP'), and provides information on the energy usage. Accordingly, a method and apparatus for controlling energy usage of the local area is provided.

1 is a diagram showing the overall configuration of a system for providing information on energy usage and controlling energy usage according to an embodiment of the present invention.

Referring to FIG. 1, the system includes an automatic detection system 100 for automatically accumulating and detecting energy usage of corresponding regions without a detection operation of a detection manpower, and an energy usage control system 110 for controlling energy usage in real time. It includes.

The automatic detection system 100 includes a meter reading engine 102, a traffic concentrator 104 and smart meters 1,2 and 106a, b, and the energy usage control system 110 includes the smart meter 1 And 2 (106a, b) and metering FAP (gauge FAP, hereinafter referred to as 'G-FAP') 108 and user terminal 110. The user terminal 110 is a terminal registered with the G-FAP 108, and in FIG. 1, only one example of the user terminal 110 registered with the G-FAP 108 will be described. However, it is a matter of course that the present invention is applicable to a plurality of user terminals.

The automatic detection system 100 performs a general meter reading operation. In detail, each of the smart meters 1,2 and 106a and b is a digital meter and measures energy consumption in the local area where it is installed and transmits it to the traffic concentrator 104. The local area represents a small communication area such as an independent office, a residence, a building, or the like. The traffic concentrator 104 accumulates and stores energy usage from each of the smart meters 1,2 and 106a and b, and transmits the energy usage accumulated at a preset time point from the operator to the meter reading organization 102. . The meter reading unit 102 checks the energy usage fee corresponding to the energy usage corresponding to the corresponding local area at a preset time point, and the smart energy usage fee is determined through the traffic concentrator 104. Meters 1 and 2 106a and b respectively impose on the user of the installed local area.

In addition, the automatic detection system 100 uses an external means such as the Internet using a request of the user terminal 110 received through the G-FAP 108 or an application pre-installed in the user terminal 110. According to the user's command to access the G-FAP 108 through the energy consumption of the metered area to the smart meters 1,2 (106a, b) and the G-FAP 108. Then, the G-FAP 108 converts the energy usage of the metered corresponding area into a data form suitable for the user terminal 110 to transmit to the user terminal 110.

 Specifically, each of the smart meters 1,2 (106a, b) is connected to the G-FAP 108 using a Zigbee (Zigbee), wired and wireless data communication method such as power line communication (PLC). That is, each of the smart meters 1,2 (106a, b) in the automatic meter reading system 100 performs a general automatic meter reading operation of transmitting energy usage to the meter reading engine 102 through the traffic concentrator 104. At the same time, by transmitting the energy consumption of the corresponding local area to the G-FAP 108, the user connected to the G-FAP 108 whenever the user terminal 110 requests or through the external means or the like. It is possible to check the corresponding energy consumption according to the conditions set in advance by. In this case, the smart meters 1 and 2 106a and b receive an energy usage request message of the user terminal 110 transmitted through the G-FAP 108 or the user terminal 110 or the external device. When a condition set in advance by a user accessing the G-FAP 108 through a means or the like is satisfied, the accumulated energy consumption of the corresponding local area is obtained from the traffic concentrator 104 to the G-FAP 108. To pass. At this time, the condition that the energy consumption is delivered to the G-FAP 108 includes 'when the cumulative amount of energy in the corresponding local area exceeds a predetermined unit of energy usage' or 'a predetermined time period'.

The G-FAP 108 receives the message requesting energy consumption directly from the user terminal 110, or according to a condition set in advance by a user's command connected through external means, etc. The smart meter 1 , 2 (106a, b) is requested energy consumption of the local area.

Subsequently, the energy consumption of the corresponding local area received from the smart meters 1 and 2 106a and b is converted into a data format for mobile communication through the G-FAP 108 and transmitted to the user terminal 110. .

For example, the data type for the mobile communication includes a short message service (hereinafter, referred to as SMS) or multimedia multicast broadcast service (MBMS) content. . The MBMS contents include a text message, multimedia information in the form of a short video, voice information, and the like.

Meanwhile, the user terminal 110 receives SMS or MBMS content for mobile communication, which is generally received through a core network (CN) regardless of the current location. In addition, when the user terminal is located in a femto cell area, which is a service area of the G-FAP 108, the amount of energy consumed in the form of SMS or MBMS content provided from the G-FAP 108 is increased. Information may also be received.

In this case, the user terminal 110 may display the received content on its screen, thereby easily grasping the energy consumption of the local area managed by the user terminal 110.

The general SMS or MBMS content is received by the macro base station or general FAP from the CN and delivered to the user terminal. However, the G-FAP proposed by the present invention separately includes a CN emulator that performs an operation for converting energy usage into a data format for mobile communication. That is, the energy consumption [information] in the form of SMS or MBMS data does not go through a normal CN, but is a femto cell area serviced by the G-FAP 108 from the CN emulator provided inside the G-FAP 108. Can only be provided within. When the user terminals enter the femto cell area of the G-FAP 108, the user terminals camp on the G-FAP 108 so that the G-FAP 108 is the corresponding user. It can be recognized that the terminals are located in their femto cell area. That is, the G-FAP 108 recognizes that the user terminals maintaining the camp on state are located in the femto cell area, and sends the SMS or MBMS data to the user terminals in the camp on state through the CN emulator. It is possible to provide information on energy usage in the form.

2 is a schematic diagram of a G-FAP according to an embodiment of the present invention. Here, the case where the user terminal 210 is located in the femto cell area of the G-FAP 200, that is, it is assumed that the camping on the G-FAP 200.

Referring to FIG. 2, the G-FAP 200 includes a FAP block 205 that operates similar to a general FAP, and a CN emulator block 210 that emulates an SMS server function of the CN. ) And the controller 215. The controller 215 controls the FAP block 205 and the CN emulator block 210.

Since the general FAP operation of the FAP block 205 is not related to the gist of the present application, a detailed description thereof will be omitted.

The controller 215 is connected to a smart meter included in the automatic meter reading system and a wired or wireless communication means such as Zigbee or PLC. The control unit 215 receives the energy usage of the femtocell area where it is located through the smart meters 1, 2 (106a, b) in the automatic meter reading system 100 of FIG. Control the CN emulator block 210 to convert to a format of receivable SMS or MBMS content. Then, the CN emulator block 210 converts the energy usage into a format of SMS or MBMS content according to the instruction of the controller 215, and converts the energy usage of the femto cell area converted into the SMS message or MBMS contents. Information about the PAP is transmitted to the FAP block 205.

On the other hand, the control unit 215 compares the energy usage and the threshold of the energy usage. The threshold value is a value set by a user connected to the G-FAP 200 through a user terminal or an external means in order to adjust the energy usage of the femto cell area. That is, the threshold value is preset in the G-FAP 200 by the user terminal 220 entering the femto cell area, or through the G-FAP through external means such as the Internet associated with a preset application. The user terminal 220 may be set before entering the femto cell area by a command of a user connected to the 200. In addition, after the initialization of the G-FAP 200, the G-FAP 200 receiving the threshold setting message transmitted from the user terminal 220 is set to the threshold value included in the threshold setting message. The threshold value may be changed or the threshold value may be changed by a command received from the external means.

As a result of the comparison, when the energy usage exceeds the threshold, the control unit 215 may provide alarm information indicating that the energy usage of the femto cell region has exceeded the threshold. To pass. Then, the CN emulator 210 converts the alarm information into a format of SMS or MBMS content under the control of the controller 215 and delivers the alarm information to the FAP block 205.

The FAP block 205 is configured to provide information on energy usage, including energy usage or alarm messages, of the femtocell region converted into SMS or MBMS content under the control of the controller 215. Transmit to the terminal 220.

The controller 215 transmits the alarm message to the CN emulator 210 as the energy usage exceeds the threshold, and then controls the power of the home appliances in the femto cell area according to a previously input priority. As a result, energy usage of the femto cell region is controlled. In detail, the controller 215 transmits a control signal for limiting energy usage, such as shutting off power of the home appliances in the femto cell area, to the corresponding home appliances according to a previously input priority. Then, the home appliances receiving the control signal cut off their power. In this case, it does not matter whether the user terminal 210 is located in the femto cell region. The pre-input priority is inputted through the user terminal 210 located in the femto cell area, or the user accesses and sets the G-FAP 215 through an external means such as the Internet associated with a preset application. It can be input through various methods.

In addition, the controller 215 receives a command message or a command requesting to control the energy usage of the femto cell area from the user terminal 210 located in the femto cell area or an external means. By controlling the power of home appliances, the energy usage of the femto cell area is controlled. In this case, the command message or command includes a power-off order of the home appliances in the femto cell area determined in consideration of the current situation regardless of the previously input priority. At this time, the current situation includes the order in which the current power consumption is highest, or the order in which there is little need to maintain the current power. Then, the control unit 215 receiving the command message or the command including the sequence is a power source device corresponding to the control signal for limiting energy usage, such as power off in accordance with the power off sequence included in the command message Send to. Then, the home appliances receiving the control signal cut off their power.

In addition, the controller 215 checks camp on states of user terminals registered in the G-FAP 200. As a result of the check, when the user terminals registered in the G-FAP 200 are all out of the femto cell area, the controller 215 may be located within the femto cell area according to the previously input priority. The control signal for limiting the energy usage, such as shutting off the power supply of the power is sent to the corresponding power devices. Alternatively, the controller 215 transmits a control signal for limiting energy usage, such as shutting off all powers of home appliances existing in the femto cell area, to the corresponding power devices. In this case, home appliances that need to be excluded from the power off may be set separately by a user connected through an external means such as the user terminal 210 located in the femto cell area or the Internet associated with a preset application.

 On the other hand, the home appliances in the femto cell area are all connected to the G-FAP 200 by using wired or wireless data communication means such as Zigbee or PLC, so that the signal transmitted by the controller 215 of the G-FAP 200 Through this, the power of the home appliances can be turned on / off.

The FAP block 205 is a media access controller for information on energy usage, including energy usage and alarm information of the SMS or MBMS format delivered from the CN emulator block 210 under the control of the controller 215. (MAC: Media Access Controller, hereinafter referred to as 'MAC') through the layer and physical (PHY: Physical, hereinafter, referred to as 'PHY') layer, etc. through the antenna of the G-FAP (200) Wirelessly delivers to the user terminal 220.
