TECHNICAL FIELD The present invention relates to a real-time power measuring apparatus configured as a receptacle type that can be conveniently used by a general public, and more particularly, to a technique for more easily identifying power consumption according to an electrical appliance used in a user's living area will be. Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is an overall block diagram illustrating a real-time power measurement apparatus according to an embodiment of the present invention.

1, the real-time power measurement apparatus 100 includes a power measurement module 110, a short-range communication module 120, a server communication module 130, a control module 140, and a switching module 150 . The real-time power measuring apparatus 100 is configured to have the same configuration as that of the real-time power measuring apparatus 200, and will be described with a different number in order to express the position of data transmission / reception.

In general, the real-time power measurement apparatus 100 is constituted by a socket mounted in an outlet for commercial power supply, and can be configured to supply commercial power to the electric apparatus through a power cord line mounted in a socket configured.

At this time, the power measurement module 110 measures the power consumption value of the electrical product.

That is, when the electric power measuring module 110 is connected to a commercial power supply source and connected to an electrical product to be measured, a value can be measured through a plurality of sensors installed therein. Typically, a current and a voltage value can be exemplified , And the power consumption value can be calculated using the measured value. In addition, the inventor may be able to measure information by adding information such as temperature and humidity more easily.

Meanwhile, the short-range communication module 120 transmits and receives the measured power consumption values between the real-time power measurement devices 100 and 200 within the communicable range.

At this time, the short-range communication module 120 performs a re-request in response to a request for a power consumption value in order to prevent the transmission / reception from occurring due to collision or loss of data during transmission / reception, The value can be collected.

In addition, the short-range communication module 120 may transmit the request including the equipment identification information when the measured power consumption value is to be transmitted to the other real-time power measurement device 200. This may be because the voltage and the rated current used for each of the electric appliances are different to distinguish the power consumption values used for each appliance. In addition, the equipment identification information may be divided into unique information that is not modified or deleted when it is first included.

The short-range communication module 120 may use Bluetooth, Zigbee, and RF (radio frequency) sensors using the well-known 2.4 GHz band. However, ZigBee, which can be operated with low power as much as the present invention is effective for energy saving, can be used as the short-range communication module 120. However, it is possible for the inventor to change the method to proceed with the design due to environmental factors.

Meanwhile, the server communication module 130 communicates with the server by connecting to the wireless network.

That is, the wireless communication network of the server communication module 120 can access the network connected to the Internet in a wireless manner so that a large amount of data can be quickly and quickly processed. A typical wireless network is a WiFi .

Based on this, the server communication module 130 can transmit the collected power consumption values to the real-time power measurement apparatus 100 and receive the on / off control command for the management of the commercial power supply from the server 300.

At this time, when the server communication module 130 and the server 300 of the real-time power measuring apparatus 100 transmit and receive information, it is preferable to proceed based on Smart Energy Profile 2.0 and 3.5 (Smart Energy Profile, SEP).

When the power consumption values collected by the server 300 are transmitted through the server communication module 130 of the real-time power measuring apparatus 100, the management area is allocated to an extra field among the information fields of the smart energy profiles 2.0 and 3.5 And may include management identification information indicating the management information.

Meanwhile, the control module 140 controls the real-time power measurement apparatus 100 according to at least one control command received.

That is, the control module 140 can be transmitted through the short-range communication module 120 by discriminating the equipment identification number included in the on / off control command received from the server communication module 130. On the other hand, if the device identification number corresponds to the device identification number, the on / off of the connected device can be controlled without using the short-range communication module 120.

In addition, the control module 140 automatically detects an event command for connecting the wireless network to the server communication module 130, and transmits the event command to the other real-time power measurement devices 200 installed in the communication range through the short- The power consumption value can be collected and stored. At this time, the control module 140 includes a memory (or storage) such as a frame memory (not shown in the drawing), and the power consumption values may be stored and stored according to the above-mentioned device identification information.

On the other hand, the switching module 150 turns on / off the commercial power supply to the electrical product.

At this time, the switching module 150 operates according to the operation of the control module 140, and is normally on in the normal state so that the power measurement module 110 can always measure the power consumption value. However, (100), the control module (140) receives the off control command from the server (300) and turns off the switch module (150) to cut off power supplied to the electrical product. On the other hand, it is also possible to release the power cut off by the ON control command.

However, when the on / off control command is transmitted to the other real-time power measuring apparatus 200, the control module 140 receives the off-control command from the short-range communication module 120 of the other real- 150 can be turned off to shut off the power supplied to the electrical product. On the other hand, it is also possible to release the power cut off by the ON control command.

In addition, the ON / OFF state of the switching module 150 refers to opening and closing of the switch, so that unnecessary power flow can be externally managed.

2 is a diagram illustrating mode switching of a real-time power measurement apparatus according to an embodiment of the present invention.

Referring to FIG. 2, a space 10 of a real-time power measurement device not connected to a wireless communication network and a space 20 of a real-time power measurement device connected to a wireless communication network can be separately described. Prior to the explanation, it is assumed that the electric appliances are connected to the real-time power measurement device 100 or the other real-time power device 200. As mentioned above, the real-time power measuring apparatus 100 and the other real-time electric power apparatuses 200 have the same configuration, and emphasize that they are classified according to the difference in position between the transmitter and the receiver.

A computer, a water purifier, a boiler, an air conditioner, and a television, which are electronic products, can be seen in a space 10 of a real-time power measuring device not connected to a wireless communication network. At this time, the real-time power measurement devices 100 and 200 connected to the electrical product can repeat only the operation of measuring the basic power consumption value because the wireless communication network is not connected.

However, when looking at the space 20 of the real-time power measuring apparatus connected to the wireless communication network, it can be seen that the power consumption values are shifted toward the computer and the boiler connected to the wireless communication network.

That is, the real-time power measuring apparatuses 100 and 200 may be configured to have a predetermined condition for the mode through a predetermined software and hardware design. Therefore, the other real-time power measuring device 200, which is not connected or paired with the wired communication network, can continuously measure the power consumption value until a target to transmit the measured power consumption value appears.

However, when the user is connected or paired with the wireless communication network at a certain point where the power consumption is measured, a preset event command is generated internally to set the real-time power measuring device 100 as a master device, The power consumption value including the equipment identification information is collected from the slave device 200.

Communication between the master device 100 and the slave device 200 proceeds through the local communication module 120 and when the slave device 200 transmits the power consumption value to the master device 100, And transmit the time including the equipment identification information at the same time as writing.

If there are two or more master devices 100, such a portion may be a measure for avoiding duplicate processing even if they are transmitted to the server 300 later because they can receive duplicate values.

Although the present invention has been described with reference to the above-described mode setting conditions for connection or pairing of a wireless communication network, the mode setting section may be changed easily by the inventor in the direction of high information utilization efficiency.

FIG. 3 is a diagram showing a practical configuration of a real-time power measurement apparatus according to an embodiment of the present invention

Referring to FIG. 3, the real-time power measurement apparatus 100 can be configured to be plugged into a socket-type socket. That is, it can be configured to be a socket mounted on an outlet for a commercial power supply, and configured so that a power cord line is mounted on the socket. And may be configured to supply commercial power to the electrical product through the power cord wire.

4 is a flowchart illustrating a method of real-time power measurement according to an exemplary embodiment of the present invention.

Referring to FIG. 4, first, the power consumption value of the electrical product is measured (S110).

Then, the control module 140 checks whether the wireless network is connected (S120). At this time, when an event command to connect to the wireless network is not detected, the power measurement module 110 continuously measures the power consumption value.

Meanwhile, when an event command to be connected to the wireless network is detected, the measured power consumption value between the real-time power measurement devices is transmitted and received within a communicable range at step S130.

At this time, in step S130, the measured power consumption values of the other real-time power measurement devices 300 installed within the communicable range are collected and transmitted and received.

Step S120 and step S130 are divided into the master device 100 and the slave device 200 according to the connection with the wired communication network mentioned with reference to FIG. 2, so that the power consumption value measured by the slave device 200 is And transmits it to the master device 100 through the local communication module 120. At this time, the power consumption value may include date, time, and equipment identification information at the time of transmission, which may be useful for information management.

Then, the mobile terminal is connected to the wireless network and transmits / receives the data to / from the server (S140).

At this time, it is possible to transmit the power consumption by the collected equipment identification information to the server through the server communication module 130, receive the on / off control command for the management of the commercial power supply from the server, Are preferably based on Smart Energy Profiles 2.0 and 3.5 (Smart Energy Profile, SEP).

Also, when the power consumption values collected by the server are transmitted from the managerial level of the data, it is possible to transmit the management identification information that can identify the management area.

Meanwhile, the real-time power measurement apparatus is controlled according to at least one control command received (S150).

At this time, in step S150, the server communication module 130 receives the on / off control command from the server 300 and discriminates the equipment identification number included in the on / off control command, And can transmit an on / off control command through the communication module 120.

Of course, if the equipment identification number matches itself, you can turn on / off the commercial power of the connected appliance.

On the other hand, the commercial power supply to the electrical product is turned on / off through the switching module 150 (S160).

The on / off control command transmitted from the server 300 may be transmitted to the switch module 150 through the control module 140 and controlled. The control module 140 receives the off control command from the server 300 and turns off the switch module 150 by receiving the off control command from the server 300. However, The power supplied to the electric appliance can be cut off. On the other hand, it is also possible to release the power cut off by the ON control command.

However, when the on / off control command is transmitted to the other real-time power measuring apparatus 200, the control module 140 receives the off-control command from the short-range communication module 120 of the other real- 150 can be turned off to shut off the power supplied to the electrical product. On the other hand, it is also possible to open the power cut off by the ON control command.
