Description

Power consumption monitoring device {POWER MONITORING APPARATUS}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power consumption monitoring apparatus, and more particularly, to an apparatus for monitoring individual power consumption of devices branched from a main power line and powered.

In general, the electricity meter indicates the total power consumption to the user by integrating and displaying the absolute value of the power amount of the individual device used by the user. However, the charge for the amount of power used is applied to the cumulative price, the more you use the more you will be charged. In addition, since charges increase in stages, charges increase rapidly when a certain amount is used.

Therefore, there has been an attempt to reduce the electricity bill in response to the electricity usage fee system by adjusting the consumption of power consumption in advance. That is, a method of controlling power usage by monitoring only abnormal power consumption in total power consumption or a method of controlling power usage by individual devices by monitoring individual power consumption for each device has been proposed.

However, the conventional power monitoring methods for controlling the power usage have a problem in that they cannot provide a satisfactory method both in terms of implementation cost of the system and in terms of accuracy and convenience of analysis of individual power consumption and total power consumption.

If the total power consumption amount is more than the total power consumption limit value, and all of the plurality of electronic devices consume power less than the power consumption limit value set in each, the controller generates the warning notification information and corresponds to the power consumption limit value. The warning notification information may be generated for an electronic device having the actual power consumption.

If the total power consumption amount is more than the total power consumption limit value and all of the plurality of electronic devices consume power less than the power consumption limit value set in each, the controller generates the warning notification information, but the actual power consumption amount is The warning notification information may be generated for the largest electronic device.

1 is a block diagram showing the configuration of a power consumption monitoring apparatus according to an embodiment of the present invention.

As can be seen with reference to Figure 1, the external power is drawn through the main power line 100 is branched to each individual power line (101 to 104) and delivered. Thus, external power is delivered to and consumed by each of the electronic devices D1 to D4. The type of the electronic devices D1 to D4 is not particularly limited, and all of the electric power consumption devices (eg, televisions, refrigerators, office equipment, automation devices, etc.) driven by electricity may correspond to the electronic devices.

The power consumption monitoring apparatus 10 according to the embodiment of FIG. 1 is connected to the main power line 100 to monitor individual power consumption of the electronic devices D1 to D4. The power consumption monitoring apparatus 10 of FIG. 1 includes a detection unit 11, a control unit 12, a storage unit 13, a communication unit 14, a display unit 15, and an input unit 16. In addition, although not shown in Figure 1, it may be configured to further include a warning notification unit.

The detector 11 is directly connected to the main power line 100 to measure power consumption supplied through the main power line 100. In this case, the measured power consumption refers to the total amount of power consumed by all the electronic devices (electronic devices D1 to D4 according to FIG. 1) connected to the main power line 100 by receiving external power.

The detector 11 may be a power meter measuring power consumption, but is not necessarily limited thereto. The total power consumption measured by the detector 11 (that is, the total power consumption consumed by all the electronic devices D1 to D4 connected to the main power line 100) may be detected and monitored at unit time intervals. The total power consumption can also be monitored continuously without time intervals. The detected total power consumption may be recorded daily, monthly, or yearly, and a target usage for daily, monthly, or yearly may be set from the total power consumption. In addition, the basic power consumption pattern for the individual electronic devices (that is, the power consumption during the reference time for each of the individual electronic devices input through the input unit 16) and the total power consumption are the information measured during the same reference time. Is used. That is, the total power consumption information measured during the same reference time as the power usage pattern of the total power consumption is used so as to be contrasted with the power usage pattern for each device for calculating the power consumption of the individual electronic devices.

In addition, the total power consumption measured by the detection unit 11 is transmitted to the control unit 12 to undergo an analysis process for monitoring the power consumption of the individual electronic devices.

The control unit 12 is connected to the detection unit 11, and is also connected to each component such as the storage unit 13, the communication unit 14, the display unit 15, the input unit 16 and the like. The control unit 12 separates power consumption for each of the electronic devices D1 to D4 using the basic power consumption pattern for each of the electronic devices based on the total power consumption transmitted from the detection unit 11. Here, the basic power consumption pattern for each electronic device is a power consumption pattern for each device during the reference time, and is input through the input unit 16, stored in advance in the control unit 12, or stored in advance in the storage unit 13. The control unit 12 may read if necessary.

Specifically, the controller 12 extracts a combination of basic power consumption patterns corresponding to the total power consumption from various combinations of basic power consumption patterns for each electronic device. The controller 12 may calculate power consumption for individual electronic devices by comparing the extracted basic power consumption pattern combination and total power consumption information.

In addition, when the calculated actual power consumption of the individual device is greater than or equal to the preset standard power consumption (power consumption limit value) for the device, the control unit 12 includes a warning including information on the corresponding device information, the amount of excess power used, and the like. The notification information may be generated and output to the communication unit 14.

The storage unit 13 is connected to the control unit 12 and stores the information obtained or analyzed through the control unit 12. On the other hand, the control unit 12 may extract information stored from the storage unit 13 and use it in the monitoring method according to an embodiment of the present invention. In the embodiment of FIG. 1, the storage unit 13 is configured to be connected to the control unit 12, but this is one embodiment and is not limited thereto. For example, the storage unit 13 may be directly connected to the input unit 16 and directly store information input through the input unit 16. As another example, the storage unit 13 may be configured in another device outside the power consumption monitoring apparatus according to the embodiment of the present invention, and may be connected to the control unit 12 through the communication unit 14 described later.

The communication unit 14 is connected to the control unit 12 and transmits signals generated by the control unit 12 to an external device, or receives and transmits signals transmitted from the outside to the control unit 12. In one embodiment, the communication unit 14 is configured to mediate signal transmission to external electronic devices, but may of course be configured to include signal transmission between internal components. In addition, the communication unit 14 transmits the warning notification information input from the control unit 12 to an external device connected through a communication network (not shown).

The display unit 15 is connected to the control unit 12, and corresponding images according to information input through the input unit 16, information processed by the control unit 12 and information or warning notification information transmitted from the control unit 12 or Display characters.

Accordingly, the display unit 15 may include various combinations of total power consumption of a plurality of electronic devices, basic power consumption patterns for each electronic device, basic power consumption patterns for each electronic device, and power consumption of individual electronic devices calculated by the controller 12. Usage amount can be displayed.

The display unit 15 according to an embodiment of the present invention receives the warning notification information transmitted from the control unit 12 and receives a warning including device information using a preset reference power consumption of power consumption, that is, a power consumption of more than the power consumption limit value. I can display it. The display method of the warning is not limited. For example, the display method may include a warning indicator flashing including information on an electronic device that uses power above a reference power consumption (consumption limit per electronic device) among a plurality of electronic devices to be connected. It may be in the form of.

According to an embodiment of the present invention, the power consumption monitoring device may further include a warning notification unit (not shown), and may generate a warning sound together with the warning display of the display unit 15 under the control of the control unit 12.

The input unit 16 may be connected to the control unit 12, and a basic power consumption pattern, a power consumption limit value, and / or a total power consumption limit value for each electronic device connected to the main power line 100 may be input. The method of inputting these pieces of information is not limited, and registration information of each electronic device may be input by a user, and power usage pattern information may be manually input for each electronic device. Here, the basic power consumption pattern of each electronic device may have various patterns according to function, capacity, and usage time of the device. The user can detect the amount of power measured through actual use of each device to obtain a power consumption pattern therefrom. In addition, the user may input a predetermined basic power consumption pattern for each device to the input unit 16.

Alternatively, as another embodiment, the controller 12 may measure power consumption for each device to calculate an actual power consumption pattern for each device. In more detail, the controller 12 may directly detect turn on / turn off of a power source of an individual electronic device connected to the main power line 100 or may use a known means. . In this case, when a specific electronic device is turned on / off in a situation where other electronic devices are used in the same manner, the control unit 12 is a difference in the total power consumption received from the detection unit 11, and thus the actual consumption of the specific electronic device. Power pattern can be detected. In this case, the control unit 12 updates the basic power consumption pattern of the electronic device stored in the storage unit 13 using the actual power consumption pattern according to the setting, or later displays it on the display unit 15 so that the user It is possible to select whether to update the basic power consumption pattern information of the device.

According to an embodiment of the present invention, a user may set a desirable power consumption for reducing power consumption of each electronic device. In this case, the control unit 12 may set the information input through the input unit 16 as the power consumption consumption (consumption limit value) of the device, and store the information in the control unit 12 or the storage unit 13. .

2 is a block diagram of a control unit of the power consumption monitoring apparatus according to an embodiment of the present invention.

According to FIG. 2, the controller 12 includes a power consumption pattern extraction module 120, an individual power consumption analysis module 121, a power consumption warning determination module 122, and an information and signal generation module 123. The power consumption pattern extraction module 120 extracts a basic power consumption pattern for each electronic device previously stored in the storage unit 13 or input through the input unit 16. The basic power consumption pattern of the electronic device will be described later in detail with reference to FIGS. 3 and 4.

The power consumption pattern extraction module 120 selectively extracts a basic power consumption pattern for an electronic device currently connected to a main power line among electronic devices registered in the power consumption monitoring apparatus. As described above, the power consumption pattern extraction module 120 may extract the basic power consumption pattern for each electronic device stored in the storage unit 13. Alternatively, according to another embodiment, the basic power consumption pattern for each measured and updated electronic device may be extracted based on a user input input through the input unit 16. The extracted basic power consumption pattern for each electronic device is transmitted to the individual power consumption analysis module 121.

In addition, the power consumption pattern extraction module 120 may combine the basic power consumption patterns for a plurality of electronic devices connected to the main power line in various ways to extract a total pattern according to the combination (hereinafter, referred to as a 'total power consumption pattern'). It may be. That is, the total power consumption pattern may be a pattern generated by combining the basic power consumption patterns of various electronic devices. In addition, the total power consumption pattern may also be transmitted to the individual power consumption analysis module 121. However, according to the exemplary embodiment, the total power consumption pattern generated by combining the basic power consumption patterns of the electronic device may be extracted by the individual power consumption analysis module 121 in comparison with the total power consumption received from the detection unit 11. Of course.

The individual power consumption analysis module 121 constituting the control unit 12 receives the total power consumption from the detection unit 11, and the basic power consumption for each electronic device transmitted from the power consumption pattern extraction module 120 from the total power consumption. The total power consumption pattern corresponding to the actual total power consumption is extracted through various combinations of the basic power consumption pattern for the electronic device connected to the pattern or the main power line.

Then, the individual power consumption analysis module 121 combines the extracted basic power consumption patterns to form a total power consumption pattern, and calculates the actual power consumption of the electronic device constituting the total power consumption pattern. A method of calculating the actual power consumption for each specific electronic device will be described later with reference to FIG. 6.

After calculating the actual power consumption of each electronic device constituting the total power consumption pattern, the power consumption of the corresponding device may be transmitted to the information and signal generation module 123. Alternatively, the power consumption information of the device may be transmitted to the power consumption warning determination module 122 in order to determine whether the power of more than the warning limit value (power consumption limit for each electronic device) for power saving is used.

When the actual power consumption of the device is calculated and delivered to the power consumption warning determination module 122, the power consumption warning determination module 122 is the power usage limit value of the corresponding device set by the user through the input unit 16 (by electronic device) Compare and judge whether the power consumption limit value is over. If it is determined that the electric power consumption of the device is greater than the power usage limit value (power consumption limit value for each electronic device), the information and signal generation module 123 generates warning notification information for the electronic device. Further, even when the total power consumption amount is greater than or equal to the input total power consumption limit value, the signal generation module 123 generates warning notification information for an electronic device corresponding to a preset criterion (a detailed description thereof will be described later).

The information and signal generation module 123 is connected to the individual power consumption analysis module 121 and the power consumption warning determination module 122. The information and signal generation module 123 receives the individual power consumption information of the electronic device calculated by the individual power consumption analysis module 121, and receives the warning notification information generated by the power consumption warning determination module 122.

The information and signal generation module 123 collects and classifies individual power consumption information of electronic devices connected to the main power line, and transmits the information to the storage unit 13. In addition, it receives the warning notification information that is information on the electronic device that is determined to consume more than the warning limit value (power consumption limit for each electronic device) and outputs it to the communication unit 14.

The warning notification information may be transmitted to the external designated device through the communication unit 14. Alternatively, the warning notification information may be transmitted to the display unit 15, and the display unit 15 may indicate that power use of the device is greater than or equal to the reference power consumption.

On the other hand, the information and signal generation module 123 is a display unit for displaying a variety of information, including the acquired individual power consumption information, information of the corresponding electronic device requiring the warning notification information, power consumption information above the power consumption limit value, and the like ( 15) transmit the information data.

Each configuration and arrangement of the control unit 12 shown in FIG. 2 is only one embodiment, but is not necessarily limited to this embodiment. For example, the storage unit 13, the communication unit 14, and the display unit 15 connected to the control unit 12 are not necessarily connected to the information and signal generation module 123, but are connected to various configurations of the control unit 12. The information can then be instantly stored, forwarded or displayed.

3 and 4 are graphs illustrating basic power consumption patterns of individual devices used in the power consumption monitoring method according to an embodiment of the present invention.

As can be seen in Figure 3, the basic power consumption pattern of the electronic device input by the user through the input unit 16 of the power consumption monitoring device is largely the operating time (OPT) and the standby time (SBT) of the operation of the electronic device, respectively It can be divided into the power consumption of. The operation time OPT and the standby time SBT are repeated to form an operation cycle OPC of the electronic device.

The power consumed for the operation time OPT is the operating power OPP, and the power consumed for the standby time SBT is the standby power SBP. If the electronic device does not stand by while being idle but has a form of consumption in which the power is turned off and then supplied when necessary, the standby power SBP becomes zero.

The operating time (OPT) and standby time (SBT), operating power (OPP) and standby power (SBP), and operating cycle (OPC) of the electronic device are substituted for the total power consumption of the electronic device connected to the main power line. It is a comparison factor of the power pattern from which the electronic devices can be extracted.

The entire time at which the basic power consumption pattern of the electronic device is prepared may be determined as a pattern period, and the pattern period may be determined as necessary for one day, one week, one month, or one year. Preferably, the basic power consumption pattern of the electronic device may be extracted every one day. The basic power consumption pattern of the electronic device is a table showing the average power consumption obtained for each unit time based on the pattern period, but the display form can be set differently.

By determining the pattern period and obtaining the power consumption pattern of the corresponding electronic device for each unit time, a pattern of repeating the operation period OPC of the operation time OPT and the standby time SBT may be obtained as shown in FIG. 3. The basic power consumption pattern of FIG. 3 is just an example, and various patterns are obtained according to the use function and time of the electronic device, and may not be a pattern of repeating a certain operation cycle (OPC).

The basic unit time for calculating the usage pattern of the power consumption can be arbitrarily set, but preferably can be obtained from the power consumption of the electronic device measured every hour.

4 shows a graph of daily power usage of various electronic devices. That is, the pattern period of the basic power use pattern of the electronic devices shown in FIG. 4 is one day, and the unit time for obtaining the pattern is based on one hour.

In addition, the basic power consumption pattern of FIG. 4 assumes a pattern of household electronic devices connected to a main power line supplied to a home. Among the electronic devices, the basic power consumption pattern of the A device is a form in which the amount of standby power used for the standby time is relatively higher than that of other electronic devices, and the use power of the operating time driven intermittently and intensively is repeated at regular intervals. As an example of A equipment, the refrigerator which has high standby power consumption of standby time compared with other electronic products is mentioned.

The basic power consumption pattern of the B device has a low power consumption for one day and waits, but has a power consumption pattern that rapidly uses power for a short time in the morning. The B device may be an electronic device such as a washing machine or a vacuum cleaner used by housewives in the morning at home.

The basic power consumption pattern of the C device is a standby power of 0 and is connected to the main power line only when necessary to consume power. An electronic device having a power usage pattern that is driven every morning, lunch, and evening may correspond to the C device. Kitchen appliances, which are mainly used at mealtimes, may correspond to C appliances.

Finally, device D, like device C, has zero standby power and is connected to the mains power line when needed, consuming power, mainly an electronic device with a pattern that consumes large amounts of power over a fairly long period of time, usually in the afternoon or evening. Able to know. For example, the power consumption pattern of electronic devices such as televisions, computers, and air conditioners.

The basic power consumption pattern of each electronic device connected to the main power line can be obtained manually by the user using the total power consumption information, or by measuring the power consumption automatically in real time from a power meter that detects the power of the individual electronic devices. .

The basic power consumption pattern of each of the electronic devices extracted in various patterns as shown in FIG. 4 is input through the input unit 16 of FIG. 1 to be used in the power consumption monitoring method of the present invention.

Meanwhile, the power consumption limit value for each electronic device may be input through the input unit 16 and stored in the storage unit 13. At this time, the power consumption limit value for each of the electronic devices may be input to different values. For example, the power consumption limit value for the device A (ie, the device A power consumption limit value) is a value 'a', and the power consumption limit value for the device B (ie, the device B power consumption limit value) is 'b value', The power consumption limit value for the device C (that is, the device C power consumption limit value) is 'c value', and the power consumption limit value for the device D (that is, the device D power consumption limit value) is 'd value', a, b, c and d may each be the same or different from each other.

In addition, as shown in FIG. 4, when each of the electronic devices is normally operated, the power consumption of each electronic device will not exceed the corresponding power consumption limit value.

5 is a graph illustrating the total power consumption analyzed by the power consumption monitoring method according to an embodiment of the present invention.

The total power consumption (total power consumption) as shown in FIG. 5 may be detected through the detector 11 of FIG. 1 connected to the main power line.

In order to apply the power consumption monitoring method of the present invention, the detected total power consumption should be the amount of power used for the same time period as the pattern period of the basic power consumption pattern of each of the previously acquired electronic devices. In addition, the unit time for detecting the total power consumption should also be the same as the unit time of measurement of the basic power consumption pattern of the electronic device.

Therefore, when the pattern period of the basic power consumption pattern according to the embodiment in FIG. 4 is 1 day and the measurement unit time is based on 1 hour, the total power consumption of the main power line measured in FIG. 5 is 1 day for 1 hour. The amount of power measured in units.

5 is a graph illustrating the total power consumption analyzed by the power consumption monitoring method according to an embodiment of the present invention.

When the total power consumption is detected and transmitted to the control unit 12 through the detection unit 11 in the form as shown in FIG. 5, the control unit 12 uses a power usage pattern for each electronic device connected to the main power line as shown in FIG. 4. To calculate the power consumption of each device.

The process of calculating power consumption for each device is analyzed by introducing a basic power consumption pattern of individual devices from the total power consumption graph as shown in FIG. 6.

6 is a graph illustrating a process of analyzing power consumption of individual devices from total power consumption by a power consumption monitoring method according to an embodiment of the present invention.

As can be seen in FIG. 6, when the graph of the total power consumption is acquired from the detection unit 11, the graph pattern of the total power consumption by substituting the total power consumption pattern obtained from various combinations of the basic power consumption patterns of the electronic devices connected to the main power line. The total power consumption pattern matching the shape of is extracted. Then, a combination of electronic devices representing the corresponding total power consumption pattern may be known, and the total power consumption may be detected due to the use of the electronic device. Comparing the total power consumption graph of the total power consumption graph with the total power consumption pattern of the electronic device combination, the power consumption of a given electronic device may increase or decrease, which may result in a difference in height of the total power consumption compared to the total power consumption pattern. Since the graph of the total power consumption reflects the pattern combination of the electronic device, the overall form is matched and the pattern combination of the electronic device can be extracted therefrom. As described above, when comparing the total power consumption pattern according to the combination of electronic devices to the graph of the total power consumption, the comparison factors include the operating time (OPT), standby time (SBT), operating power (OPP) and Standby power SBP, and an operating cycle OPC.

In the embodiment of FIG. 6, the graph of total power consumption is derived as in the case of FIG. 5, and the basic power consumption pattern of the electronic device having the same shape is substituted. It can be seen that the result of the power pattern is synthesized. Thus, after extracting the combination of electronic devices from the total power consumption pattern that matches the shape of the total power consumption graph, the excess power consumption of each electronic device is measured to calculate the specific power consumption of the electronic device.

In the case of normal power consumption in FIG. 6, the total power consumption is in a category belonging to a graph of the total power pattern combining the power consumption patterns of the electronic devices A, B, C, and D. However, when the power consumption of any one of the electronic devices A, B, C, or D increases, the corresponding total power consumption graph shows that the increased power consumption among the total power consumption patterns of the basic power consumption pattern of the electronic device. Since it will increase in the portion corresponding to the power pattern of the electronic device, it is possible to specifically calculate the increased power consumption of the electronic device based on this.

For example, the total power consumption (total power consumption) in the P1 period is the sum of the power consumption for the corresponding time of the electronic device A and the electronic device B.

In the case of normal power consumption, the actual total power consumption is in a range equal to or less than the value PP1 plus the power amount PPa of the basic power consumption pattern of the electronic device A and the power amount PPb of the basic power consumption pattern of the electronic device B.

However, if the total power consumption during the period other than the P1 period of the total power consumption graph is within the normal graph, but the total power consumption increased to PPx in the P1 period, it can be determined that the power consumption of the electronic device B has increased. . If the power consumption of the electronic device A has risen, the total power consumption will have increased in other periods, but the increase in the power consumption in the P1 period may be considered to have increased the consumption of the electronic device B.

Then, the actual power consumption amount PPb + (PPx-PP1) of the electronic device B may be calculated by determining the increase PPx-PP1 of the total power consumption amount in the P1 period as the increase of power consumption of the electronic device B.

The control unit 12 determines whether the calculated actual power consumption of the electronic device B is equal to or greater than the reference power consumption (power consumption limit value), and if abnormal, generates warning notification information for the corresponding electronic device B to communicate with the communication unit 14. Can be printed as In addition, the communication unit 14 may transmit the warning notification information on the input electronic device B to an external device connected through a communication network. Accordingly, through an external device (eg, a mobile communication terminal), the user can easily recognize at any time and anywhere that the electronic device B consumes more than the power consumption limit value.

As an example of power amount analysis of another electronic device, the total power consumption of the P2 period is the sum of the power amounts recorded in the patterns of the electronic device A and the electronic device D. If only the total power consumption during the P2 period is increased and the total power consumption for the remaining period is within the normal range, it can be seen that the increased power consumption of the P2 period is the amount of power used by the electronic device D.

Therefore, the sum of the increased power consumption in the P2 period and the amount of power recorded in the pattern of the electronic device D can be obtained to obtain the actual power consumption of the actual electronic device D. Even in this case, if the actual power consumption of the electronic device D is equal to or greater than the corresponding power consumption limit value (that is, the d value), the control unit 12 may generate warning notification information for the electronic device D and output it to the communication unit 14, The communication unit 14 may transmit the warning notification information about the electronic device D to an external device.

On the other hand, the above described a case in which the warning notification information for the electronic device is notified only when the actual power consumption of each electronic device is more than the reference power consumption (that is, the power consumption limit value). However, although the actual power consumption of each electronic device is not more than the power consumption limit value, the total power consumption of the entire electronic device may be more than the reference power consumption (that is, the total power consumption limit value).

For example, the total power consumption limit value may be input through the input unit 16 and stored in the storage unit 13. In addition, the controller 12 is an electronic device corresponding to a preset standard when the total power consumption consumed by all the electronic devices connected to the main power line 100 is greater than or equal to the total power consumption limit value (hereinafter, referred to as “alert target electronic device”, That is, the 'alert target electronic device' refers to an electronic device corresponding to a preset criterion).

That is, when the total power consumption consumed by all the electronic devices connected to the main power line 100 is greater than or equal to the total power consumption limit, the control unit 12 uses the actual amount of power consumed among the electronic devices (ie, the actual power consumption) to each device. The warning target electronic device that is greater than or equal to the set power consumption limit value may be detected to generate warning notification information on the detected electronic device. For example, the controller 12 may determine that the total power consumption consumed by all the electronic devices connected to the main power line 100 is greater than or equal to the total power consumption limit, and that the electronic devices A, B, and D are actually compared to the normal state within the same period. Assume a case where it is detected that power consumption has increased. In this case, when it is determined that only the electronic device D consumes more than the power consumption limit value, the controller 12 may generate warning notification information for the electronic device D (that is, when the electronic device D is a warning target electronic device). . On the other hand, if it is determined that the electronic device A in addition to the electronic device D consumes more than the power consumption limit value in the above-described example, it is apparent that the control unit 12 may generate warning notification information for the electronic device A as well.

In addition, even if the total power consumption amount is more than the total power consumption limit, it is assumed that all the electronic devices consume less than the corresponding power consumption limit value. In this case, the control unit 12 may generate warning notification information for the electronic device to which the actual power consumption is closest to the corresponding power consumption limit among the electronic devices connected to the main power line 100. That is, suppose that the electronic device A has a power consumption limit of 10 watts, the electronic device B has a power consumption limit of 50 watts, the electronic device C has a power consumption limit of 5 watts, and the electronic device D has a power consumption limit of 10 watts. . At this time, the controller 12 may generate warning notification information about the electronic device C.

In addition, even if the total power consumption is more than the total power consumption limit, it is assumed that all the electronic devices consume less than the corresponding power consumption limit while using the power that is less than the same value for each power consumption limit. . That is, suppose that the electronic device A has a power consumption limit of 10 watts, the electronic device B has a power consumption limit of 10 watts, the electronic device C has a power consumption limit of 10 watts, and the electronic device D has a power consumption limit of 10 watts. . In this case, the controller 12 may generate warning notification information for the electronic device having the largest power consumption (when the electronic device having the largest power consumption becomes the warning target electronic device). That is, when the electronic device A consumes 1 kilowatt, the electronic device B 10 kilowatts, the electronic device C 15 kilowatts, and the electronic device D consumes 5 kilowatts, the control unit 12 generates warning notification information for the electronic device C. Could be.

That is, when the total power consumption is greater than or equal to the total power consumption limit value, the control unit 12 may generate warning notification information for an electronic device that is actually using power greater than or equal to the power consumption limit value. If there is no device, the alarm notification information can be generated for the electronic device that is closest to the power consumption limit value. If all the electronic devices use less than the same power level in the power consumption limit value, the alarm will be warned for the electronic device with the highest power consumption. Notification information may be generated.

In addition, as described above, the warning notification information corresponding to each electronic device generated by the controller 12 may be output to the communication unit 14 and transmitted to an external device connected through a communication network.

7 is a flowchart illustrating a power consumption monitoring method according to an embodiment of the present invention.

As described above, the configuration of the power consumption monitoring apparatus illustrated in FIGS. 2 and 3 is just an embodiment, and may be implemented in various components by being further subdivided into functions or integrated in reverse. Therefore, hereinafter, in describing the power consumption monitoring method according to the embodiment of the present invention, the subject will be described mainly using the power consumption monitoring apparatus.

First, a basic power consumption pattern is acquired for each electronic device (S1). This is not obtained in the power consumption monitoring apparatus according to an embodiment of the present invention, but is obtained based on power consumption actually measured for each electronic device from the outside. In the manufacturing stage of the electronic device or in a separate process, the power consumption may be manually or automatically detected using a power amount detector, and then the basic power consumption pattern may be extracted for each electronic device based on the power consumption.

The basic power consumption pattern for each device is transmitted to the power consumption monitoring apparatus according to an embodiment of the present invention and stored in the storage space of the power consumption monitoring apparatus (S2). The basic power consumption pattern may be formed in various patterns according to criteria such as capacity, measurement time, measurement period, etc., even in one electronic device, and may be classified and stored according to various criteria.

Subsequently, the power consumption monitoring apparatus measures the total power consumption supplied through the main power line (S3). The total power consumption measured at this time is the sum of the power used by each electronic device that is supplied with power through the main power line.

Next, the power consumption monitoring apparatus extracts a power consumption pattern combination (that is, total power consumption pattern) for each device for electronic devices using actual power by being connected to the main power line from the total power consumption measured in step S3 (S4). ).

Subsequently, after extracting the total power consumption pattern of the electronic devices actually connected to the main power line, the actual power consumption of each of the electronic devices is calculated (S5). Here, when the power consumption is out of the error range from the sum of the power consumption per unit time of the basic power consumption pattern for each device, the power consumption pattern during the other period of the electronic devices that consumed the power during the period is analyzed and actually excessively powered. Detects the electronic devices consumed and calculates the actual power consumption of the electronic device.

In the next step, it is determined whether the actual power consumption of each electronic device connected to the main power line is greater than or equal to the corresponding power consumption limit value (S6). Can be generated. That is, the warning notification information may be generated for the electronic device that actually consumes more than the power consumption limit value (S7).

Thereafter, the generated warning notification information is transmitted to the connected external device through the communication network (S8). If the actual power consumption of all electronic devices is less than the corresponding power consumption limit, the power monitoring process is terminated. Since the power monitoring process can be configured to monitor continuously without being limited to one-time, if the power use of the electronic device is less than the power consumption limit value for each electronic device in the above process, the process returns to step S3 without ending the monitoring process and the main power line. It is obvious that the total power consumption of can be measured again.

8 is a flowchart illustrating a power consumption monitoring method according to another embodiment of the present invention.

As described above, the configuration of the power consumption monitoring apparatus illustrated in FIGS. 2 and 3 is just an embodiment, and may be implemented in various components by being further subdivided into functions or integrated in reverse. Therefore, hereinafter, in describing the power consumption monitoring method according to the embodiment of the present invention, the subject will be described mainly using the power consumption monitoring apparatus. In addition, the steps to be described below may be steps performed after steps S1 to S5 described with reference to FIG. 7 are performed. Therefore, description of steps S1 to S5 in FIG. 8 will be omitted.

In step S86, it is determined whether the total power consumption of all the electronic devices connected to the main power line is greater than or equal to the total power consumption limit value, and if the total power consumption value is greater than or equal to the total power consumption limit value, generates warning notification information on the warning target electronic device corresponding to the preset criteria. (S87). For example, if the total power consumption is greater than or equal to the total power consumption limit, it may be possible to generate the alert notification information for the electronic device that actually consumes power above the corresponding power consumption limit.

In another example, when all the electronic devices consume less than the corresponding power limit, even though the total power consumption is greater than or equal to the total power limit, the warning notification information for the electronic device closest to the corresponding power limit. Can be generated.

In another example, although the total power consumption is more than the total power consumption limit, all the electronic devices consume less than the corresponding power consumption limit and all use the power that is not equal to the corresponding power limit. In this case, it is possible to generate warning notification information for the electronic device having the highest power consumption among the electronic devices.

Thereafter, the generated warning notification information is transmitted to the connected external device through the communication network (S88). If the total power consumption is less than the total power consumption limit, the power monitoring process is terminated. Since the power monitoring process can be configured to monitor continuously without being limited to one-time, if the total power consumption is less than the total power consumption limit in the above process, return to step S3 without ending the monitoring process to reduce the total power consumption of the main power line. It is obvious that it can be measured again.

The power consumption monitoring method according to the present invention described above may be embodied as computer readable codes on a computer readable recording medium. Computer-readable recording media include all kinds of recording media having data stored thereon that can be decrypted by a computer system. For example, it may be a ROM (Read Only Memory), a RAM (Random Access Memory), a magnetic tape, a magnetic disk, a flash memory, an optical data storage device, or the like. In addition, the computer-readable recording medium may be distributed and executed in a computer system connected to a computer network, and may be stored and executed as a code readable in a distributed manner.
