BRIEF DESCRIPTION OF THE DRAWINGS The above and other objects, features and advantages of the present invention will become more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which: .

In the following description, a detailed description of known technologies related to the present invention will be omitted when it is determined that the gist of the present invention may be unnecessarily blurred. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing an energy information providing apparatus (hereinafter referred to as an energy information providing apparatus) through a change of a power discrete signal according to an embodiment of the present invention.

Referring to FIG. 1, an energy information providing apparatus according to an embodiment of the present invention includes an input unit 100, a delta calculating unit 200, an energy increase / decrease index adjusting unit 300, and a display unit 400.

In this embodiment, the input section 100 receives a power disconnection signal.

In this embodiment, the delta calculation unit 200 calculates a power delta that defines a variation amount of a power value equal to or larger than a predetermined reference value from the power discrete signal, and calculates a power double delta from the power delta to define the variation amount of the delta.

In the present embodiment, the energy increase / decrease index adjuster 300 increases or decreases the energy change index indicating the change in state of the electronic device or the electronic equipment at the time of the double delta change.

In the following embodiment, the display unit 400 displays the energy increase / decrease index.

Hereinafter, the information providing method through the energy information providing apparatus described above with reference to FIG. 2 will be described in detail.

2 is a flowchart illustrating an energy information providing method (hereinafter referred to as an energy information providing method) through a change of a power discrete signal according to an embodiment of the present invention.

Referring to FIG. 2, the energy information providing method according to the present embodiment includes a power discrete signal input step S100, a power delta calculation step S200, a power double delta calculation step S300, , And an energy increase / decrease index display step S500.

First, in the power discrete signal input step S100 of the present embodiment, the input unit 100 receives a real time power discrete signal. In this embodiment, the discrete signal may be a signal value indicating the measured power value as a sequence, and in this embodiment, may be composed of numerical information calculated based on a reference value, which will be described later.

In the next power delta calculation step S200, the delta calculation unit 200 calculates a power delta that defines a variation amount of the power value equal to or larger than a predetermined reference value from the power dissipation signal. That is, the power delta dP [n] = P [n] -P [n-1] is extracted from the real-time power discrete signal as the power value P [n] , and n-1 is a value measured immediately before).

The next power double delta calculation step S300 calculates the power double delta which defines the amount of change of the delta from the power delta. That is, in this embodiment, the ON and OFF of the electric devices and the accessories in the electric device are detected through the power double delta (ddP [n] = dP [n] -dP [n-1]).

In this embodiment, the start of the transient state of the electronic device or the accessories of the electronic device is determined according to the change amount of the double delta, and the change amount of the double delta is continuously added to determine the end of the transient state.

Next, the energy increase / decrease index adjustment step (S400) increases or decreases the energy increase / decrease index indicating that the energy increase / decrease index adjuster 300 changes state of the electronic device or the electronic accessories at the time of change of the double delta.

In the present embodiment, the energy increase / decrease index display step (S500) displays the energy increase / decrease index to / from the display unit 400 to the user.

That is, from the moment when the power double delta value is not zero, the operation of the electric device or the accessories in the electric device is generated by the user action (including the operation specific to the device by programming) The interval in which the double delta value is zero is regarded as a steady state and there is no change in the electric appliance or the accessories in the electric appliance, and the instantaneous energy increase / decrease index is fixed.

Referring to Fig. 3, Fig. 3 is a diagram showing a case where an electric appliance or an accessory of an electric appliance is turned on by a user's action.

In this embodiment, the power doubling delta value of the power discrete signal collected in real time increases the instantaneous energy increase / decrease index by 1 from the moment when the power double delta value first indicates a positive non-zero value to the beginning of a transient state due to on, And begins to sum the values.

The time at which the summed value becomes 0 is regarded as the end of the transient state, which means the use of one device that uses electric energy by user behavior or programming operation specific to the electric device, This means that actions can be taken to perform energy savings through automatic or manual control for the purpose of reducing energy consumption.

That is, in this embodiment, the start of the transient state of the electronic device or the accessory of the electronic device is determined according to the change amount of the double delta, and the change amount of the double delta is continuously added to determine the end of the transient state.

In the present embodiment, various types of power discrete signal characteristics are shown according to the operation characteristics of the device itself during the transient state in which the turn-on of the household appliances or the accessories in the household appliances occurs, all of which can be detected through the above-described algorithm.

At this time, the algorithm uses the sum of simple power power delta, power double delta, and power double delta (it is not storing past history through simple addition, subtraction, ) Operation speed and memory occupancy are very low, and it is advantageous that it can be easily implemented even at a low-cost CPU.

3 (B) and 3 (C), in this embodiment, the change of the state is recognized based on the power delta of the reference value or more. Therefore, The same result can be calculated through a simple calculation.

Also, it is possible to display the real-time data directly from the data in real time instead of the back-tracking method based on the information of the specific period collected in the past, thereby promptly informing the user of the phenomenon.

For example, referring to FIG. 7, if the user turns on the living room lighting and turns on the TV in the living room in the evening, the instantaneous energy reduction index should be 2. However, if you are displaying 3, you can easily participate in energy saving activities by yourself, for example, whether the user turned on the lights in the room before leaving the living room. As the index keeps close to zero, energy conservation activities are performed well, so it is possible to induce energy conservation activities by user recognition from time to time.

In addition, even if a condition such as a compressor in a refrigerator repeatedly turns on and off periodically to maintain the temperature due to the programming characteristic inherent to the electric device, when the index periodically rises, Can reduce the lifting cycle of the index by reducing the opening of the energy-saving activities.

4, FIG. 4 is a diagram showing a case where accessories of an electric appliance or an electric appliance are turned off by a user's action.

In the present embodiment, the power double delta value of the power discrete signal collected in real time starts to sum up the power double delta value from the moment when the transient state starts from the moment when the power double delta value is first turned off, The time point at which the value becomes 0 is regarded as the time point when the transient state ends, and the instantaneous energy increase / decrease value is decreased by -1.

This means that one device that uses electrical energy by user behavior or a programming operation unique to the electric device means that the user performs an energy saving operation by automatically or manually controlling for the purpose of energy saving .

It is possible to detect various kinds of power discrete signal characteristics according to the operating characteristics of the device itself during the transient state in which the components in the home appliance or the home appliance are turned off.

That is, as described above with reference to FIG. 3, the same result can be calculated by a simple calculation also for various variations according to the operation of the components or the like that generate the power variation below the reference value .

In this embodiment, the amount of change in the power value can be determined to increase or decrease based on the predetermined base power.

That is, referring to FIG. 5, FIG. 5 is a diagram showing a case where accessories of an electric device or an electric device are continuously turned on and off according to a user's action.

In the present embodiment, for a device that performs on-off from a power discrete signal collected in real-time during the operation of an electric device and an accessory in the device in a transient state without a steady state, a base low power Pbase , Additional supplementary explanation in the following 2) information is additionally stored in real time, so that the instantaneous energy increase / decrease index can be detected through this.

The instantaneous energy increase / decrease index is incremented by 1 from the instant when the power double-delta value is collected in real time and the double delta value is not zero but the positive value is first displayed, and the power double delta value is added from that point Started. The instant when the summed value becomes 0 is regarded as the instant when the transient state is ended and the case where the power P [n] at that point of time is equal to the base low power Pbase is considered as the case, -1 decreased. This indicates that one device that uses electrical energy has been turned on and off by user behavior or programming operations specific to the device.

Referring to FIG. 6, FIG. 6 is a diagram illustrating an energy increase / decrease index detection result through a real-time power discrete signal.

In this embodiment, the result of the execution of the algorithm for detecting the instantaneous energy increase / decrease index from the power double delta of the time power discrete signal allows the user to easily grasp the components in the electric appliance or the electric appliance in which the energy is used, Indicators indicate control opportunities that users can take action on themselves to save energy, so that voluntary and active energy saving actions can be performed by simply striving to keep that indicator at zero in real time.

Hereinafter, the base power used in the present embodiment will be described in detail.

In the present embodiment, the base power can be detected using the energy increase / decrease index and the power P [n] measured at the present point in time.

With regard to initialization, in this embodiment, the base power is initialized to the initial power of the power discrete signal, and the energy increase / decrease index is initialized to an initial value together with the initialization of the base power. At the start of operation of the measuring device, the currently measured power (P [n]) is designated as the initial low power, and the instantaneous energy increase / decrease behavior index can be initialized to zero.

With respect to the update of the base power, in the present embodiment, the base power is updated by comparing the measured power value at the time when the power increase / decrease value does not change with the initial value and the base power .

That is, when calculating the power power delta (dP [n]) from the real-time power discrete signal, there is no change in the power power delta as a result of correcting the measurement noise or error If the currently measured power P [n] that is newly updated under the condition of being kept at 0 is smaller than the base low power Pbase, the base low power is continuously updated in real time.

Also, the base power may be updated if the energy increase / decrease is an initial value and the power delta and the double power delta are negative values, when the transient state ends.

That is, when the instantaneous power decrease index is 0 and the power power delta and the power double delta have a negative value, the instantaneous energy decrease index is kept at 0, and the transient state is ended through the above algorithm And updates the post-low-power (Pbase).

In this embodiment, the base low power is generated mainly by the standby power and is an electric energy that is consumed at all times irrespective of the energy change index of the user. Therefore, the energy that can be further reduced by the user habit due to the constant and fixed loss Reduction.

That is, in the step S500 of displaying the energy increase / decrease index in this embodiment, additional base energy can be displayed to the user so that additional energy saving can be performed.

When changing the operating conditions of electrical equipment and electrical equipment that generate low power after recognition by the user (for example, disconnecting from an outlet to an electrical equipment that is not normally used) can be detected by updating the base power .

This improves the accuracy compared to the method of extracting only the lowest value in the real-time power discrete signal (when detecting a simple minimum value, a transient state value can be detected in the device's off state so that the actual steady state minimum value and other information There is a possibility of an error to provide).

In addition, there is a case where the exponent count of the rise and the exponent count of the descent during the lapse of a certain time after the instantaneous energy decrease index rises based on the base low power (for example, when the electric device is turned on individually, If the real-time power is restored at the low power level, the residual indicator of the energy increase / decrease index is initialized to zero, and it is corrected by the incomplete behavior in the matching of the on and off states in the future. Accuracy is improved by correcting errors.

Conversely, if there is a mismatch due to a large number of exponential decays compared to the exponential count of the rising exponent (for example, when turning on multiple devices at once with a multi-tap and turning them off individually), it is possible to check the low- However, if the index tries to change from 1 to 0, the corresponding index is kept at 1, and when it returns to the initial low power by the final descent, it is initialized to zero and the error due to incomplete behavior in the future matching Can be corrected.

Next, reference values for detecting the on and off transient states of the electric devices and the accessories inside the electric devices will be described.

In this embodiment, the reference value can be adjusted by comparing the change target value of the energy increase / decrease index with the change value of the energy increase / decrease index for a predetermined period.

In the initial setting, a reference value (for example, 1% in a 3-kW power supply household, such as 30 W) for detecting the on and off state of an electric appliance and an accessory inside the electric appliance by user behavior from a real- The maximum number of instantaneous energy increase / decrease detections by the detecting device during a predetermined period (for example, one day) is set as the index target number (for example, seven high-speed instantaneous power consumption devices among many electric devices in the measurement target customer) If the detected number is lower than the target number, the reference value is lowered. On the other hand, if the detected number is higher than the target number, the reference value is automatically adjusted to match the instantaneous energy increase / decrease index detection target number.

In this case, when the reference value is lowered, the reference value for performing the update is always compared with the maximum value of the fluctuation width in a real-time state in a steady state other than the transient state, that is, The variable maximum value is used as the new reference value.

On the contrary, when the reference value is increased, the reference value to be updated can be used as a new reference value by adding a predetermined minimum change value (for example, 1 W).

In this way, it is possible to overcome the limitation of extraction of characteristics for each user, which is automatically optimized for each installation target user in various installation environments having many unspecified electric devices and can be generalized to a specific limited standard, It is possible to estimate and utilize the high-speed instantaneous power consumption device and the parts in the power consumption device which should have the power consumption.

Furthermore, in the present embodiment, when the reference value is significantly lowered for detection in the power delta detection of the real-time power discrete signal, an algorithm for reducing the measurement noise and the error can be implemented with the probability including the experiential value.

That is, when the adjusted reference value is less than or equal to a predetermined value, the ratio of recognizing the steady state by the reference value in the transient state in which the state of the electronic device or the accessories of the electronic device changes for a predetermined period, Or a state in which a state change of an accessory of an electronic device does not occur is detected as a transient state by the reference value.

More specifically, in the simple calculation of the power delta in the real-time power discrete signal, when the reference value is much lower than a predetermined value for detection, it is liable to generate an improper output due to measurement noise and error.

Therefore, when a specific reference value (Pth) is set and it is recognized that a transient state has occurred, if a change occurs within the corresponding value, a method of recognizing it as a normal state rather than a transient state is mainly used. It is not completely free from measurement noise or error, and there is a need to improve the sensitivity with a simple algorithm that introduces the probability including the experience and the cumulative integration concept

The probability including the experiential value may be a preset value from the user or a value extracted from the real-time power discrete signals during a predetermined period to be set as a reference (for example, a time period for remeasurement via the app or the web during a specific period for optimizing user modification) Includes probabilities that include four base experience points.

Detection of a state change when the adjusted reference value is equal to or less than a predetermined value is as follows.

First, the real-time power dissipation signal is collected for a certain period of time, and the simple transient state and the simple steady state exceeding the reference value from the signals are indicated as real-time power discrete signals. In addition, in the section for collecting the power discrete signal, the actual steady state period in which there is no variation of the actual apparatus is determined by the user setting or the electric apparatus autonomy And records the time point at which it occurs.

The first is the actual transient state in which electrical components and components in the electrical device turn on or off. The number of power dissipation signals and the ratio of the number of simple discrete power dissipation signals, which are actually recognized as steady states despite the transient state, It sets the probability including the state experience value, and sets the probability of this probability as the probability including the transient state experience value in the transient state.

On the contrary, the second is the ratio of the number of actual discrete power dissipation cores that do not fluctuate in electrical equipment and electrical equipments to the number of power disconnection signals in simple transient states that are actually recognized as transient despite the steady state. It sets the probability including the experience value, and sets the probability of the probability including the steady state experience value in the steady state.

The power delta detection that detects the change from the steady state to the transient state can be classified into a simple transient / steady state generated based on the reference value in the real-time power discrete signal, a probability including transient state / transient state experience value, / Log value for the ratio of the probabilities including the steady state experiential value as the transient state detection index and accumulating the cumulative value, and recognizing that the transient state has completely entered when exceeding the specified value.

The power delta detection, which detects the transition from transient state to steady state, is a function of the transient / steady state generated based on the reference value in the real-time power discrete signal, the probability including the transient state / transient state experience value, It is used as a steady state detection index as a logarithm of the ratio of probabilities including the steady state experiential value, and recognizes that it has completely entered the normal state when it exceeds a specific value while subtracting it from the accumulated value.

More specifically, the error reference value eps is set as a reference value for a change in the amount of electricity used for the power value P that can be regarded as noise or measurement error.

On the other hand, the probability of a case where the difference between P of the current time t and P of the previous time t-1 is less than or equal to the error reference value and the case where the difference is larger is calculated by the following equation.

[Equation 1]

P (transient state) = n (the number of cases where the change in power consumption is less than or equal to eps) / n (the number of transient states)

P (steady state) = n (number of cases where the change in power consumption is greater than eps) / n (number of steady states)

At this time, a cumulative sum or difference of logarithms of the ratio of P (transient state) to P (steady state) is calculated, and the transient state or the normal state is determined when the accumulated value exceeds a specific value.

Since the specific value by the accumulation can acquire the reference information for the user environment in the probability setting including the initial experience value, the optimization can be performed for each user to be installed in various installation environments based on the reference information. It is possible to improve the detection accuracy by reducing the measurement noise and the error of the sensor.

In the present embodiment, the energy information providing method divides the collected power discrete signals for a predetermined period into a plurality of intervals according to a predetermined ratio, and then provides information about a period corresponding to the measured power discrete signal to the user And a second step of providing the second step.

That is, it is possible to implement a power consumption proper / over state detection algorithm based on the instant power consumption ratio of the real-time power discrete signal.

In detail, the instantaneous power values are divided into a specific number (for example, a total number of measurement cycles per one measurement cycle) during a predetermined period (for example, one week of the first week of each month or weekday / Etc.), stores them in an array, and arranges them in descending or ascending order.

Thereafter, the values of the respective boundary lines according to predetermined ratios corresponding to upper, middle, and lower parts of the database (for example, upper 10% - middle 60% - lower 30%, etc.) And set it as a detection value.

Next, the instantaneous power consumption amount is automatically detected by the user according to the part of the instantaneous power consumption ratio set based on the boundary reference detection value.

This makes it possible to automatically detect the appropriate / excessive state of real-time power usage tailored to the individual user by automatically optimizing the usage of the electric devices and the accessories in the electric devices according to user behavior habits in various installation environments and user conditions.

In addition, in the present embodiment, the step of displaying the energy increase / decrease index (S500) may further include a step of displaying the result values generated by the above-described algorithm in addition to the energy increase / decrease index as a real time power, a low power, Based power consumption.

It is not easy for ordinary users to acquire meaningful information easily and use it for energy saving by simply displaying real-time power dissipation signal (kW).

Referring to FIG. 7, FIG. 7 shows a power discrete signal and a method of displaying an energy increase / decrease index. In this embodiment, the user recognition rate is improved as shown in FIG. 7 and the number is kept close to 0, Lt; / RTI >

In addition, the low-power and real-time power can be graphically displayed together to easily convey perceptions of behavior that lowers the low-power or keeps the real-time power close to low-power.

Real-time power (kW) can be used to generate direct indicators of energy savings. However, since the amount of energy (kWh) used is directly related to the electricity price of individual users, It is also possible to express the cumulative amount of use (measurement) and the cumulative amount of expected ending date (apart from the estimation algorithm) up to now so as to establish a self-plan for the utilization of the user's electric energy.

In addition, when the real-time power discrete signal is included in the appropriate power consumption ratio based on the instant power consumption ratio based on the instantaneous power consumption amount ratio based on the algorithm, the electricity consumption amount is small and the total data expression picture Alternatively, it is possible to reflect the entire background change in the color step (blue, green, yellow, yellow, red, etc.) in the graph and transmit it as semantic information easily understood by the general user.

According to the present invention described above, it is possible to reduce the number of parts of an electric appliance or a part of accessories in an electric appliance or an electric appliance by a user action at present through delta and double delta values generated based on current and previous sampled values in a power- By detecting the on and off states and designing an algorithm to detect the momentary energy change index of the present moment, it is possible to induce voluntary energy saving activities based on user recognition that can minimize the numerical value.

In addition, it detects and expresses the base low power (Pbase) which is the lowest power consumption at all times in the power discrete signal collected in real time, so that it is utilized for reducing standby power. In addition, it is used to set initialization criterion for double delta which is the detection criterion of instantaneous energy increase / decrease index, so that it corrects the error situation in which the number of times of turning on and off of the electric appliance or some of the accessories in the electric appliance is wrong. Can be improved.

In addition, the most important variable in detecting the turn-on and turn-off of the electric device or some of the accessories in the electric device by the user action in the power discrete signal collected in real time is an algorithm that automatically adjusts the reference fluctuation of the delta It is possible to improve the accuracy of the user energy management object by performing an algorithm that satisfies the detection target of the high momentary power consumption electric device and the electric appliance.

In addition, when the fluctuation of the delta reference is much lowered for detection, it is possible to detect a change in the meaningful power consumption, that is, the delta value, together with the reference value of the delta which can be considered as measurement noise or error, A calculation based on the experiential value which may be a value defined by the service provider in advance of the probability of the transient state in which the operation of the substantial on and off operations may occur and the probability of the normal state may be performed to exclude the measurement noise or errors coming from the real- It is possible to improve the accuracy of the delta with respect to the transient state and the steady state change of the device by designing and expressing an algorithm for detecting the power change delta caused by a change in the operation state of a specific electric device or an electric device.
