2 is a block diagram of a power consumption management system of a home according to the present invention.

As shown, the power usage management system is connected to the power line flowing into the home 100, the power sensor module 20 for measuring the power consumption and transmitting the power consumption measured by the power usage manager 70 through the power line And, connected to the power sensor module 20 is supplied with power of the premises 100 to perform a unique function, and the operation information and / or individual instantaneous power consumption including a function module currently operating power usage manager 70 It is connected to the power line of the washing machine 30, the air conditioner 40, the microwave oven 50 and the electric iron 60, and the home 100, which is an electric device to be transmitted to the power consumption and electricity from the power sensor module 20 The power consumption manager 70 calculates power consumption of each electric device and / or power consumption of a functional module of the electric device according to operation information received from the devices 30, 40, and 50 and / or individual instantaneous power consumption. .

In detail, as shown in FIG. 3, the power sensor module 20 is connected to a power line introduced into the home 100 to measure power consumption 21 for measuring power consumption, and the measured power consumption is measured by the power line ( A transmission means 22 for transmitting to the power usage manager 70 in the form of a predetermined data format (for example, data according to the LnCP protocol) via a kind of network). The power sensor module 20 includes a conventional power meter 1 and transmission means (for example, a power line modem) connected to the power meter 1 to transmit the measured power consumption through the power line. The currently installed power meter 1 may be utilized, and instead of the conventional power meter 1, the power meter 21 and the transmitter 22 may be integrated.

In addition, the transmission means 22 receives the electric power and power consumption from the electric power measuring means 21 and transmits it through the power line, the electric device (30, 40, 50, 60) and the power sensor module 20a and the power usage manager The power is supplied to the 70, and the power consumption is transmitted to the power usage manager 70. Alternatively, although not shown, power passing through the electric power measuring means 21 may be directly supplied to the power line in the home without passing through the transmitting means 22, and the power transmitting means 22 may be configured to transmit only the power consumption. .

In addition, the power age measuring means 21 may receive power through the first power line and output the power through the second power line, or receive power through the second power line and output the power through the first power line. For example, if the power line flowing into the home 100 is the first power line, the power line of the home 100 becomes the second power line, and the power applied to the first power line is transferred to the home 100 through the second power line. Is approved. In addition, the power line connected to the electric iron 60 becomes the first power line, the power line of the home 100 becomes the second power line, the power applied to the second power line to the electric iron 60 through the first power line. Supplied. At this time, the power does not pass through the transmitting means 22, but the power supply for the operation of the transmitting means 22 is to be made.

Next, the washing machine 30, the air conditioner 40, and the microwave oven 50, which are electric devices, are connected to the power line of the home 100 to receive power, and the electric devices use the power usage manager 70 through the power line. And a communication module (for example, a power line modem) for enabling communication with a power sensor, and a power sensor for measuring power currently consumed by the device.

With the configuration of such an electric device, FIG. 4 shows a schematic configuration diagram of the air conditioner of FIG. 2. As shown, the air conditioner 40 is a controller 41 for controlling the entire blowing and / or cooling cycle, and a communication module connected to the power line to enable communication between the controller 41 and the power usage manager 70 ( 42), the outdoor unit fan motor 43 performing the operation of the outdoor unit, the indoor unit fan motor 44 performing the operation of the indoor unit, and the power consumption of the entire air conditioner 40 by measuring the individual instantaneous power consumption controller And a power sensor 45 applied to 41.

Here, the outdoor unit fan motor 43, the indoor unit fan motor 44, the power sensor 45, and the like are referred to as functional modules in the present specification, and the function modules perform predetermined operations to use power consumption of a predetermined size. It shows. At this time, the controller 41 itself also becomes one function module. Basically, performing one function is divided into one function module. For example, if the operation of the outdoor unit fan motor 43 is one operation, it becomes one function module. However, when operating in high speed operation and low speed operation, when different power consumption is used, the same function may be performed, but two functional modules may be distinguished.

The washing machine 30 and the microwave oven 50, which are other electric devices, are also composed of a single or a plurality of functional modules according to their functional operation, as in the above-described air conditioner 40, and have a communication module. These communication modules 42 may be built-in type that is mounted internally at the time of manufacture of the electric device, or may be an external type that enables communication by connecting a predetermined terminal to an already manufactured electric device.

In FIG. 2, unlike the washing machine 30, the air conditioner 40, and the microwave oven 50, which are generally other electric devices, the electric iron 60 is a communication means such as the communication module disclosed in FIG. 4 due to the small size and the generation of heat. It is difficult to mount it. As such, the electric device, in which the communication means is not provided technically, costly or for the convenience of the user, is directly supplied with the power sensor module 20a as described above, as shown in FIG. 2. The power sensor module 20a measures the power consumption through the power amount measuring means 21 according to the on / off state of the electric iron 60, and the power consumption manager 70 measures the power consumption through the transmission means 22. To send. That is, when the power sensor module 20a transmits power consumption through the power line, this power consumption also serves as operation information indicating that the electric iron 60 is turned on / off. The power usage manager 70 determines the operation of the electric iron 60 through the reception or size of power consumption. Here, the power sensor module 20a has the same configuration as the power sensor module 20 described above.

Next, the power usage manager 70 is capable of communicating with the electric devices 30, 40, 50 and the power sensor modules 20, 20a through a general-purpose network such as a power line to manage the overall power usage of the home 100. It's a kind of network manager. The power usage manager 70 may be a communication device embedded in a personal computer or a set-top box or a predetermined electric device (for example, a refrigerator). In addition, the power usage manager 70 may be connected to an external network (for example, a dedicated network such as the Internet network) to allow communication.

The power usage manager 70 is actually a communication interface for at least one or more controllers, power line communication (i.e. general purpose network communication) and communication with an external network (i.e. dedicated network communication), received operation information and instantaneous It consists of a storage means for storing the power consumption, and the power management according to the present invention by the data flow between these components, but such data flow is clearly recognized by those familiar with the technical field to which the present invention belongs, No explanation is given.

The power usage manager 70 is configured for the electrical devices 30, 40, 50, 60 and the power sensor modules 20, 20a connected to the power lines of the home 100 before the power management according to the present invention is performed. Information is stored, and identification numbers (e.g., address information, product information, etc.) for distinguishing them are stored together.

In addition, the power usage management system may include an indoor environment sensor (not shown) and an outdoor environment sensor (not shown) for acquiring environmental information inside and outside the home. The indoor environment sensor and the outdoor environment sensor, for example, measure the current temperature, humidity, dryness, wind speed, and the like, and transmit the environmental information inside and outside the home to the power usage manager 70. The power usage manager 70 controls all and / or partial functions of electric devices (eg, air conditioners 40, refrigerators, etc.) whose functions are closely related to these environmental information, so that efficient power usage can be achieved. You may.

In particular, when the air conditioner (that is, the air conditioning function module) of the electrical equipment, if the function is properly controlled according to the indoor temperature and the outdoor temperature, it is possible to reduce the power usage. For example, when the difference between the indoor temperature and the outdoor temperature is large, it is necessary to weaken the cooling operation of the air conditioner 40 or change it to a blowing operation, and the power usage manager 70 according to the environmental information reflecting such a situation. By controlling the operation of the air conditioner 40, the air conditioner 40 can be prevented from being overdriven and inefficiently consumed.

5 is a flowchart illustrating a method of calculating power consumption of each electric device in the power usage management system according to the present invention.

In detail, in step S51, the power usage manager 70 receives the instantaneous power consumption from the power sensor module 20, 20a. In this case, the power usage manager 70 may wait for transmission from the power sensor modules 20 and 20a or actively request and receive current instantaneous power consumption from each of the power sensor modules 20 and 20a.

At this time, the power sensor module 20, 20a is instantaneous power consumption when the change in the instantaneous power consumption is more than a predetermined size, and / or at a predetermined time interval, and / or when there is a request from the power usage manager 70 To the power usage manager 70.

In step S52, the power usage manager 70 receives operation information and / or individual instantaneous power consumption for the function (or function module) currently operating from each electric device 30, 40, 50. In this case, if the power usage manager 70 does not receive the operation information and / or the individual instantaneous power consumption, the process proceeds to step S51 to receive the instantaneous power consumption or wait until the operation information is received for a predetermined time. Alternatively, the power usage manager 70 may actively request and receive current operation information and / or instantaneous power consumption from each electric device 30, 40, or 50.

In addition, the electrical devices 30, 40, and 50 transmit operation information and individual instantaneous power consumption at the start of each operation and at predetermined time intervals, or operation information and individual instantaneous power consumption from the power usage manager 70. When there is a request for power, or when there is a change in the operation of the function module, the operation information and the individual instantaneous power consumption can be transmitted accordingly.

Since the operation information and the individual instantaneous power consumption should correspond directly to the instantaneous power consumption received from the power sensor modules 20 and 20a, the power usage manager 70 performs steps S51 and S52 in an appropriate order. It can be done with

In step S53, the power usage manager 70 determines operation information, individual instantaneous power consumption, and / or instantaneous power consumption for each electric device 30, 40, 50, 60 and / or function module received. Record in the power consumption table. This record consists of storing in a predetermined storage means.

A detailed embodiment of this power consumption table is disclosed in FIG. As shown, the horizontal axis represents an electric device (for example, a washing machine, an air conditioner, a microwave oven, etc.) and its functional modules (M1, M2, M3), and the vertical axis represents the number of times operation information has been received. In this case, individual instantaneous power consumption (unit: watts, W) is displayed in the rightmost column. For example, in the first operation information, the function module M1 of the washing machine operates, and the instantaneous power consumption at this time is 300W.

In step S54, the power usage manager 70 forms a predetermined system of equations with a plurality of times of operation information and corresponding instantaneous instantaneous power consumptions, thereby consuming power (or instantaneous consumption) for each electric device and each functional module. Calculate the power). That is, since one simultaneous equation is generated at each number of times, these simultaneous equations for each of the functional modules M1 to M3 are generated, and power consumption of each of the functional modules M1 to M3 can be calculated according to a predetermined algorithm. Can be. For example, the simultaneous equation in the first time is M1 = 500, the simultaneous equation in the second time is M1 + M2 + M3 = 400, and the simultaneous equation in the third time is M3 = 50.

As a result, the power consumption of each of the functional modules M1 to M3 is calculated in the result column at the bottom of the power consumption table of FIG.

The power consumption according to the functional module of each electric device may be calculated through a system of equations between operation information of each electric device and corresponding instantaneous power consumption. The power consumption of the functional modules calculated as described above is the basis for calculating the total instantaneous power consumption according to the operation information of the electric devices 30, 40, 50, and 60 at a predetermined number of times. The total instantaneous power consumption transmitted from the power sensor module 20 in this number should be the same. This determination of identity may be additionally performed to ensure the reliability of the value of power consumption of each of the calculated functional modules. If it is not the same, the power usage manager 70 may discard the power consumption of the function module thus calculated and newly calculate it. In addition, such a mismatch may be caused even when an electric device that is not connected to the power sensor module 20a is installed in the home 100, and thus the user may be informed of such a mismatch.

In this case, the power usage manager 70 may include a predetermined power sensor to measure power consumption consumed by the power sensor, and calculate power consumption according to its own function module in the same manner as described above. Therefore, the total instantaneous power consumption consists of the power consumption of the power usage manager 70 and the power consumption of the electrical devices 30, 40, 50, and 60. However, in order to focus on the control of the home electrical equipment 30, 40, 50, 60, the description of the power consumption of the power usage manager 70 is only omitted. In the following specification, although the power consumption of the power consumption manager 70 is not considered in the description of the total instantaneous power consumption and the progressive power consumption, it is understood that it is considered as practical because it is for convenience of description. Should be.

In step S55, the power usage manager 70 determines whether the power consumption of all the electric devices and / or functional modules of the premises 100 connected to the power line has been calculated, otherwise proceeds to step S51. If all have been calculated, the process proceeds to step S56 to save the power consumption table and ends.

As described above, the power usage management system calculates the power consumption of the electric devices 30, 40, 50, 60 of the home 100 using the power consumption of each of the functional modules M1 to M3. Thus, since the power usage manager 70 recognizes the power consumption of each of the function modules M1 to M3, if it finds that the power consumption is greater than or less than the sum of the power consumption of the function module in operation, It may be determined that an overload or other failure has occurred in a function module of a specific electric device, and a message for this may be provided to the user. In addition, the power usage manager 70 may find a function module associated with this overload or failure using a power consumption different from the power consumption of the previously stored function module through the simultaneous equations of the above-described method, and this function module and / or Information about the electrical device may be provided to the user.

7 is a flow chart of a power management method performed in the power usage management system according to the present invention.

In detail, in step S71, the power usage manager 70 receives a power management method from a user. The input process may be performed through an input means mounted on the power usage manager 70 or through an input means mounted on another electric device, and then may be performed by receiving the input power management method. In addition, when there is no input for the power management method from the user, the power usage manager 70 performs a control operation according to the power management method, or otherwise separate control if there is an automatically set power management method. You may not perform the operation.

Here, the power management method is, for example, a first optimal use method of setting an electric charge peak value and allowing the current electric charge to be within this electric charge peak value, or setting a predetermined power supply peak value. For example, the method may be a second optimal use method in which progressive power consumption of a predetermined period is achieved within this supply power peak value.

In detail, as the first optimal use method, the power usage manager 70 uses the optimum method of using each of the electric devices 30, 40, 50, and 60 (for example, the use method of each function module has a room temperature of 28). The cooling cycle may be operated only when the temperature is higher than the above degree, and the blowing cycle may be operated at a temperature below that of the cooling cycle, or the electric equipment may be used when the electric charge is low.

In addition, in the second optimal use method, the power usage manager 70 controls the instantaneous power consumption of each of the electric devices 30, 40, 50, and 60. It is to stop the operation or to interrupt the partial operation (ie, the function module). For example, by raising the operating temperature of the cooling cycle of the air conditioner 40, the operation of the indoor unit fan motor 43 is stopped, or the operation of the boiler is stopped by lowering the operating temperature of the boiler, or the operation of the television. To stop. However, the interruption of the operation is prioritized on the user's use or stability of the system. For example, maintaining a constant temperature, such as a refrigerator, has a lower priority, while being able to postpone its use, such as an electric iron, has a higher priority, and also has a security system in the home 100. In this case, the priority should be lower because it must always be in operation, and the whole or partial function of the electric equipment is interrupted in the order of higher priority.

The first and second optimal use methods described above are just one embodiment of the power management method and may be applied together. In addition, the power management method may simply provide a user with a current electric charge and / or progressive power consumption, or provide a list of currently operating electric devices to guide the user to control a predetermined operation.

In step S72, the power usage manager 70 receives the instantaneous power consumption from the power sensor module 20, 20a and / or the power sensor 45 of the electrical device (30, 40, 50), step S73 ), The progressive power consumption for the predetermined period of the entire electrical device (30, 40, 50, 60) is calculated. In this case, the predetermined period generally means a period from the base date of the billing to the present, but may be a separate period (for example, three days or one week) determined by the user.

In step S74, the power usage manager 70 calculates the electric charges charged to date through the calculated progressive power consumption. In order to calculate the electric charge, the power consumption manager 70 stores an algorithm for calculating the electric charge through the progressive power consumption, or connects to a server (not shown) of a power supply company through an external network for the progressive power consumption. It is also possible to check the electricity bill by sending a message and receiving the electricity bill calculated by the server. The electricity rate at this time may be a fixed electricity rate or an expected electricity rate.

In step S75, the power usage manager 70 compares the current electricity rate with a preset electricity rate peak value. If the current electric charge is equal to or greater than the electric charge peak value, the flow proceeds to step S76, otherwise, the flow goes to step S77.

In step S76, the power usage manager 70 controls the electrical devices 30, 40, 50, 60 according to the stored power management method.

In step S77, the power usage manager 70 compares the progressive power consumption with a predetermined supply power peak value. If the progressive power consumption is equal to or greater than the supply power peak value, control proceeds to step S76 to perform control according to the power management method, otherwise proceeds to step S78.

In step S78, the power usage manager 70 provides the user with the current progressive power consumption and / or electricity rates.

The above-described steps S75 and S77 may be reversed, and only one step may be performed according to a user's selection.
