DETAILED DESCRIPTION Hereinafter, embodiments of the present invention in which the above object can be specifically realized are described with reference to the accompanying drawings.

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 a washing machine which is connected to the power sensor module 20 to receive power from the home 100 to perform a unique function, and to transmit operation information including a function module currently operating to the power usage manager 70. 30, an air conditioner 40, a microwave oven 50 and an electric iron 60, and connected to the power line of the home 100, the power consumption from the power sensor module 20 and the electrical equipment (30, 40, 50) 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 the received operation information.

In detail, the power sensor module 20, as shown in Figure 3, the power amount measuring means 21 for measuring the power consumption, and the measured power consumption in the form of a predetermined data format (for example, LnCP protocol Data), and the transmission means 22 transmits to the power usage manager 70. 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 transmitting means 22 receives the electric power and power consumption from the electric power measuring means 21, and transmits the electric devices 30, 40, 50, 60, the power sensor module 20a, and the electric power usage manager 70. Power is supplied to, and power consumption to the power usage manager 70.

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 (eg, a power line modem) to enable communication with the system.

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), an outdoor unit fan motor 43 that performs the operation of the outdoor unit, and an indoor unit fan motor 44 which performs the operation of the indoor unit.

Here, the outdoor unit fan motor 43 and the indoor unit fan motor 44 and the like are referred to as functional modules in the present specification, which indicates that the functional modules perform a predetermined operation to use a predetermined power consumption. 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, the electric iron 60 is generally different from other electric appliances, such as the washing machine 30, the air conditioner 40, and the microwave oven 50, such as the communication module disclosed in FIG. 4 due to the small size and the generation of heat. It is difficult to mount the means. 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. In addition, by controlling the operation of the air conditioner 40, it is possible to prevent the air conditioner 40 is overdriven to consume power inefficiently.

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. At this time, 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 power sensor module 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 operation S52, the power usage manager 70 receives operation information on a function (or a function module) currently being operated from each electric device 30, 40, or 50. At this time, if the power usage manager 70 does not receive the operation information, the process proceeds to step S51 to receive the instantaneous power consumption, or waits until receiving the operation information for a predetermined time. Alternatively, the power usage manager 70 may actively request and receive current operation information from each electric device 30, 40, or 50.

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

Since the operation information should correspond directly to the received instantaneous power consumption, the power usage manager 70 may perform steps S51 and S52 in an appropriate order.

In step S53, the power usage manager 70 records the operation information and the instantaneous power consumption for each electric device 30, 40, 50, 60 and / or function module received in the predetermined 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 in the figure, the horizontal axis discloses each electric machine (washing machine, air conditioner, microwave oven), and its functional modules M1, M2, M3, M4, M5, M6, M7, M8, and the vertical axis. Denotes the number of times operation information has been received, and instantaneous power consumption (unit: watts, W) is disclosed in the rightmost column. For example, in the first operation information, the function module M1 of the washing machine and the function modules M4 and M5 of the air conditioner operate, and the instantaneous power consumption at this time is 500W.

In step S54, the power usage manager 70 forms a predetermined system of equations using a plurality of times of operation information and corresponding instantaneous power consumption, so as to consume power (or instantaneous power) for each electric device and / or each functional module. Calculate the power consumption). That is, since one simultaneous equation is generated at each number, these simultaneous equations for the respective functional modules M1 to M8 are generated, and the power consumption of each functional module M1 to M8 can be calculated according to a predetermined algorithm. Can be. For example, the simultaneous equation in the first time is M1 + M4 + M5 = 500, and the simultaneous equation in the second time is M1 + M2 + M3 + M4 + M5 = 600.                 

As a result, the power consumption of each of the functional modules M1 to M8 is calculated in the lowermost result column of the power consumption table of FIG. 6, and among the calculated functional modules M1 to M8 of the corresponding electric device. The power consumption may be calculated as the sum of the power consumptions of the relevant function modules M1, M2, M3, M4, M5, and M6, M7, M8.

At this time, the power usage manager 70 may calculate the power consumption according to its 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 this 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, this is for convenience of description and should be understood as practical. do.

In step S55, the power usage manager 70 determines whether power consumption of all the electric devices and / or functional modules of the premises 100 connected to the power line has been calculated, and if not, 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 power consumption of the electric devices 30, 40, 50, and 60 of the home 100 using the power consumption of each of the functional modules M1 to M8. Thus, since the power usage manager 70 recognizes the power consumption of each of the function modules M1 to M8, 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 can find a functional module associated with this overload or failure using a power consumption different from the pre-stored power consumption through the simultaneous equations of the method described above. Information 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 a power management method from the user, the power usage manager 70 performs a control operation according to the power management method if there is an automatically set power management method, or otherwise separate control operation. May not be performed.

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, the need to maintain a certain temperature, such as a refrigerator, has a lower priority, and the ability to delay its use, such as an electric iron, can have a higher priority, and in the case of the security system of the home 100 The priority should be lower because it must be active at all times, disrupting the overall or partial functionality of the electrical equipment in the order of its highest 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 modules 20 and 20a, and calculates the progressive power consumption for a predetermined period in step S73. 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.

The present invention having such a configuration has an effect of calculating the power consumption of each electric device in the home and / or the power consumption according to the function module of the electric device.

In addition, the present invention has the effect that it is possible to provide a variety of methods for power control to the user according to the operation information of the electrical equipment in the home, and each power consumption and / or electricity bill.
