Referring to FIG. 1, a power consumption management apparatus using power line communication includes a wired / wireless gate 4, a plurality of sensors 7, a PLC control unit 6, a wireless pager 5, and a power saver 3. It is made to include.

First, a description will be given of a path through which electricity is supplied within a generation, and electricity (commercial power) supplied from an electricity supplier is supplied to the power saver 3 through the meter 1 and the backflow blocker 2, and the power saver 3 The electricity supplied to the PNL 34 is supplied to the plurality of PNL 34 through the inlet 31, the breaker 32, and the instrument transformer 33 forming the power saver 3, and the electricity is again supplied by the plurality of PNL 34. Branched and fed into the household.

In the household, a plurality of sensors 7 are installed. The sensors 7 include sensors having various sensing functions such as external intruder detection, fire detection, temperature detection, smoke detection, and each of the sensors 7 It has a wired or wireless communication function to transmit the sensing information to the control server 37 through the wired or wireless gate (4).

In the generation s, a PLC control unit 6 including a plurality of PLC slaves 62 connected to each other through a power line to control electrical appliances is installed, and the PLC control unit 6 includes a control server 37 and a power line and a wired / wireless gate ( It is further included a PLC master 61 for communicating via 4).

In addition, the PLC slave 62 is provided with a standby power cut-off button 63 for cutting off the power supplied to the electrical products to remove the standby power consumption.

The wired / wireless gate 4 has a function of relaying devices within a generation to communicate with each other, and is also connected to an external internet network so that the control server 37 can communicate with external devices connected through the internet network.

2 is a block diagram showing the configuration of a power saver according to the present invention. Referring to Figure 2 will be described in detail the operation of the power consumption management apparatus according to the present invention including a power saver.

The digital meter 1 constituting the power saver 3 detects and stores the amount of electricity supplied into the household in real time, and displays the accumulated and stored amount of electricity through the display unit 36 for each day, month, time zone, and year.

When the amount of electricity is displayed through the display unit 36, the user can check this and be motivated to save and use electricity.

Meanwhile, the control server 37 reads the accumulated electricity amount sensed by the digital meter 1 monthly, for example, connects to the Internet network through the wired / wireless gate 4 and transmits it to the server of the electricity supplier company. It is not necessary to read the meter of each household directly, and it is possible to read the meter automatically and accurately, thereby reducing the damage caused by the metering error.

In addition, according to the power consumption management apparatus using the power line communication according to the present invention, the user can be connected to the control server 37 from the outside through the Internet network to check the state of the electrical appliances in the household one by one.

That is, when the user connects to the control server 37 after connecting to the Internet network using a computer from the outside, the control server 37 confirms the user through a series of authentication process, and confirmed through the PLC control unit 6 Inform the user of the possible operating state of the electrical appliance.

For example, the control server 37 provides the user with the operation status of the electrical appliance such as a TV, a washing machine, a refrigerator, a computer, an air conditioner, and the like, so that the user uses the state information of the electrical appliance provided by the control server 37. It is possible to check the on / off status of electrical appliances currently installed in their household. In this state, when the user transmits a control command for controlling the state of a specific electric product in operation to the control server 37, the control server 37 transmits the transmitted control command to the PLC controller 6 via the power line. Will print.

The PLC master 61 of the PLC control unit 6 outputs the control command to the PLC slave 62 to which the electric product to be controlled by the control command transmitted from the control server 37 is connected, and receives the control command. One PLC slave 62 controls the operation of the connected electrical appliance. The control command for the electrical appliance includes control for turning on or off the electrical appliance.

One or more PLC slaves 62 installed in a household may have their own outlets and be connected to a power line. In addition, it is preferable to be able to plug an electric product into an outlet provided in the PLC slave 62. That is, the PLC slave 62 may include a function of supplying electricity to a connected electric product while having a power line communication function.

In addition, by further installing the standby power cutoff button 63 in the PLC slave 62, a user directly operates the standby power cutoff button 63 to completely cut off electricity that can be supplied to the electrical appliance, thereby reducing standby power consumption. I will be able to give.

On the other hand, according to the present invention, it is possible to quickly inform the outside about the external intrusion or fire occurrence occurring in the household using the information detected from each sensor (7).

That is, various types of information detected by the sensor 7 are collected at the wired / wireless gate 4 by the wired / wireless communication function and supplied to the control server 37, and the control server 37 detects and detects the respective sensors 7 from the respective sensors 7. The transmitted information may be used to determine an emergency situation such as whether an external intruder has occurred or a fire has occurred.

By this determination, when an invasion situation or a fire situation of an external intruder is detected, the control server 37 operates the wireless pager 5 to notify the emergency situation currently detected by a predetermined police station, fire station or user's mobile phone. The wireless pager 5 immediately transmits a text message or a voice message under the control of the control server 37.

In addition, the PLC control unit 6, the control server 37, and the wired / wireless gate 4 of the present invention communicate with each other through a power line installed in the household to transmit and receive information to each other, and communication data communicated between these devices are blocked backflow. The part 2 does not leak out of the power saver 3.

That is, the reverse flow blocking unit 2 includes a function of blocking the communication data between the various devices installed in the household from being leaked out while supplying electricity supplied through the meter 1 to the household. .

3 shows the configuration of such a backflow blocker 2 in a block. FIG. 3 (a) shows the low flow filter 21 which blocks the low frequency band signal as the backflow blocker 2 between the meter 1 and the power saver 3.

Typically, electricity has a frequency of 60 Hz, and communication data communicated over power lines has a frequency of about 1 KHz.

Therefore, if the low pass filter 21 for blocking the frequency below about 120Hz between the meter 1 and the power saver 3, the communication data can be blocked while passing electricity.

FIG. 3 (b) is provided with a bandpass filter 22 for passing only signals of a specific frequency band as the backflow blocker 2. When the frequency band of the bandpass filter 22 is set to 1 to 120 Hz, Electricity passes and communication data can be blocked.

In addition, FIG.3 (c) is the backflow blocking part 2 comprised using the diode 23. As shown in FIG. The diode 23 is forward-connected from the meter 1 to the power saver 3 so that electricity supplied from the meter 1 to the power saver 3 passes and flows back from the power saver 3 side to the meter 1 side. Data can also be configured to be blocked.
