Definitions

the disclosure relates to an air conditioning apparatus and a control method thereof, and more particularly, to an air conditioning apparatus modifying schedule information on the basis of collected environmental information and a control method thereof.
An air conditioning apparatus is an apparatus placed in a space, such as a house, an office, a shop, or a crop-cultivating house, to control a temperature, a humidity, a degree of cleanliness, and a flow of air therein, thereby maintaining a comfortable indoor environment for people to live or a suitable indoor environment for crops to grow.
the conventional air conditioning apparatus determines an operation state and an output intensity based on a current temperature.

ordinal numbers such as “first” and “second” may be used to distinguish the elements from each other. These ordinals are used to distinguish identical or similar elements from each other, and the use of such ordinals should not be understood as limiting the meanings of the terms. As an example, elements combined with such ordinal numbers should not be limited in use order, arrangement order, or the like by the numbers. If necessary, the ordinal numbers may be used interchangeably with each other.
first”, “second”, and the like may be used to describe various elements, but the elements are not to be construed as being limited by these terms. The terms are used only to distinguish one element from another element.
module refers to an element that performs at least one function or operation.
the element may be implemented with hardware, software, or a combination of hardware and software.
a plurality of “modules”, “units”, “parts”, or the like may be integrated into at least one module or chip and implemented by at least one processor, excluding the case where each of the plurality of “modules”, “units”, “parts”, or the like should necessarily be implemented with individual specific hardware.
any part when any part is described as being connected to another part, this includes not only a direct connection but also an indirect connection through another medium.
the terms “load”, “load information” and “load value” may all be used in a similar sense. Values of the collected environmental information are all in different units, and they can be converted into one representative value. Thus, the load means that the values of the collected environmental information are converted into one representative value. Through the load (load information, load value) converted in this way, a user may easily compare a current state of an air conditioning apparatus depending on time.
FIG. 1 is a block diagram illustrating an air conditioning apparatus 100 according to an embodiment of the disclosure.
the air conditioning apparatus 100 may include a driver 110 , a sensor 120 , a memory 130 , and a processor 140 .
the air conditioning apparatus 100 is an apparatus placed in a space, such as a house, an office, a shop, or a crop-cultivating house, to control a temperature, a humidity, a degree of cleanliness, and a flow of air therein, thereby maintaining a comfortable indoor environment for people to live or a suitable indoor environment for crops to grow.

the driver 110 may be a part performing a cooling function.
the driver 110 may be configured to perform various functions of the air conditioning apparatus 100 , such as cooling, heating, and air cleaning.
the driver 110 is not limited to any specific function and may refer to a component of the air conditioning apparatus 100 that may be controlled by a user's command or by the processor 140 .
the sensor 120 may measure a temperature, a humidity, a size and a form (structure) of a space, the number of persons, and activity states of the persons. Specifically, the size and the form (structure) of the space may be sensed to ascertain whether the air conditioning apparatus 100 is installed in a circle space or in a quadrangle space and to measure a wideness.
the sensor 120 may measure both a temperature around an indoor unit and a temperature around an outdoor unit.
the sensor 120 may determine body temperatures of persons in an air conditioning target around the indoor unit.
the sensor may measure and compare the body temperatures of the persons to determine whether the persons currently feel hot.
a thermal imaging camera or the like may be used to measure the body temperatures of the persons.
it is not limited to the thermal imaging camera, and a heat sensor and a heat sensing camera that are capable of measuring a body temperature of a person may be used.
the senor 120 may collect ambient environmental information of the air conditioning apparatus 100 .
the sensor 120 may check how many persons are present in a space where the air conditioning apparatus 100 is installed.
the sensor 120 may check what motion is taken by a person.
the sensor 120 may check whether the person is running. If it is confirmed by the sensor that the person's motion is exercise, a temperature may be set to be lowered than that as currently set. For this operation, the sensor may use a motion sensor or a human body detection sensor.
the senor 120 may measure a body temperature of a person using a heat sensor, a heat sensing camera, or the like.
the body temperature of the person is measured by the sensor 120
the processor 140 may determine whether the body temperature of the person is in such a degree that a predetermined operation state needs to be changed.
the senor 120 may measure a body temperature for each of the persons in the air conditioning target. Accordingly, the air conditioning apparatus 100 may be controlled to direct wind toward a person having a higher body temperature.
the memory 130 may store values measured by the sensor 120 therein.
the values measured by the sensor 120 may be stored in the memory 130 every predetermined time, and the predetermined time may vary depending on user's settings. Further, a storage cycle may be on a weekly basis.
the air conditioning apparatus 100 may operate in such a pattern that the values are stored for each classified time zone on each day of the week from Monday to Sunday. The detailed storage method will be described later with reference to FIG. 14 .
the memory 130 may store a plurality of schedule information for each day of the week, and the processor 140 may control the driver 110 on the basis of schedule information corresponding to a current day of the week among the plurality of schedule information.
the memory 130 may store a plurality of initial schedule information, and the processor 140 may control an operation of the driver 110 on the basis of initial schedule information selected by a user among the plurality of initial schedule information.
the memory 130 may be implemented as a non-volatile memory, a volatile memory, a flash-memory, a hard disk drive (HDD), a solid state drive (SSD), or the like. Meanwhile, the memory 130 may be implemented not only as a storage medium in an electronic device but also as an external storage medium, e.g., a micro secure digital (SD) card, a universal serial bus (USB) memory, or a web server through a network.
SD micro secure digital
USB universal serial bus
the processor 140 may control an operation of the driver 110 on the basis of schedule information in which an operation state is defined according to a time change, and modify the schedule information on the basis of environmental information collected during a predetermined period.
the schedule information may be information including environmental information stored for each hour and an operation state of the air conditioning apparatus 100 on the basis of the environmental information.
the environmental information may include at least one of an indoor temperature, an outdoor temperature, a humidity, the number of persons in an air conditioning target, body temperatures of the persons, or an amount of dust.
the environmental information may be collected or measured by the sensor 120 .
the processor 140 may modify the schedule information by classifying the environmental information as stored in the memory 130 for each time zone, and comparing the classified environmental information for each time zone with an operation state for each time zone in the schedule information.
the schedule information may be information including environmental information stored for each hour and an operation state of the air conditioning apparatus 100 on the basis of the environmental information.
the schedule information may be a set of control commands in which collected environmental information and information on operation states corresponding to the environmental information are arranged to correspond to time. For example, in schedule information on a daily basis, commands set to perform specific operations at specific times from morning to evening may be stored. Therefore, when the schedule information is applied to the air conditioning apparatus 100 , the processor 140 may automatically control the air conditioning apparatus 100 even though the user does not personally control the air conditioning apparatus 100 .
the schedule information may include environmental information stored for each hour and an operation state of the air conditioning apparatus 100 based on the environmental information, which will additionally be described later with reference to FIG. 12C .
the environmental information may include at least one of an indoor temperature, an outdoor temperature, a humidity, the number of persons in an air conditioning target, or an amount of dust.
the environmental information may be collected or measured by the sensor 120 .
the operation state may include information on operation modes and output intensities.
the operation modes may refer to different modes such as cooling, heating, blowing and air cleaning functions
the output intensities may refer to different outputs in the same operation mode, such as cooling (strong), cooling (medium), and cooling (weak).
the operation state is not limited to the operation modes and the output intensities, and may additionally include information on functions and operations.
the operation modes and the output intensities are not limited to the above-described elements, and may include additional functions.
the air conditioning apparatus 100 may determine an operation state on the basis of the collected environmental information and control the driver 110 of the air conditioning apparatus 100 according to the operation state.
the processor 140 may predict an operation state for each time zone from the environmental information for each time zone using a predetermined learning model.
the predetermined learning model may be a classification system using a series of machine learning algorithms based on neural networks, which will be described in detail later with reference to FIG. 11 .
the processor 140 may predict a load for each time zone on the basis of the classified environmental information for each time zone.
the load may be predicted by various methods.
One of the various methods may be a method of converting each data of the environmental information into an index. For example, if the number of persons is 30 and a current temperature is 27 degrees, +30 may be assigned for the number of persons and +5 may be assigned for the current temperature of 27 degrees.
a load may be 35.
Each of the assigned numerical values may be changed according to user's settings.
the operation state for each time zone in the schedule information may be modified on the basis of the predicted load for each time zone. As in the above-described example, it is assumed that the current number of persons is 30 and the current temperature is 27 degrees. Here, the predicted load is 35 and an operation state may be determined to correspond to the load value of 35. The operation state may be set to a cooling (strong) mode, and the operation state corresponding to the load value of 35 may be changed according to user's settings.
a load may be determined by combining a plurality of load information, not based only on information at a current time. For example, when it is assumed that a load at 9 o'clock yesterday is 35 and a load at 9 o'clock today is 30, a load tomorrow may be predicted to be 32.5, which is an average value of 35 and 30. Here, only the average value is exemplified, but a predicted load value may be determined through various mathematical methods.
the processor 140 may modify the operation state for each time zone in the schedule information by determining an operation mode of the air conditioning apparatus 100 and an output intensity in the operation mode based on the predicted load for each time zone.
the predicted load is calculated as 32.5.
a load at the corresponding time is stored as 40 in the schedule information that is already applied to the air conditioning apparatus 100 , there is a load difference of 7.5.
the processor 140 may modify the load, the operation mode, the output intensity, and the like included in the schedule information on the basis of environmental information collected during a predetermined period.
the processor 140 may modify the operation state for each time zone in the schedule information on the basis of the predicted load for each time zone and spatial information of the air conditioning target.
the spatial information may be a size, a form, a purpose of use, a degree of outdoor air blocking, and a degree of air tightness of an air conditioning target.
the size of the air conditioning target may refer to a wideness or a volume
the form of the air conditioning target may be a structural shape such as a rectangle or a circle.
the purpose of use of the air conditioning target may be a working space, sports facilities, performance facilities, a classroom, a hotel, or the like.
the degree of outdoor air blocking and the degree of air tightness may refer to an insulation state of a wall and an opened or closed state of a window or a door.
the environmental information collected based on these information may be reflected in a load.
the processor 140 may allocate a larger load value to a larger space and control the air conditioning apparatus 100 to operate in a cooling mode with a larger output intensity corresponding to the larger load value. That is, the processor 140 may control the air conditioning apparatus 100 while reflecting data on spatial information.
the processor 140 may control an operation of the driver 110 on the basis of the collected environmental information rather than the schedule information.
the processor 140 may modify the schedule information on the basis of environmental information collected for a predetermined period. To modify the schedule information, however, it is required that data having a great difference from existing data should not be data obtained through one-time measurement. This is because the collected data may exceptionally have a high or low measurement value only at a current time simply due to an exceptional situation. To modify the schedule information as previously stored in the memory 130 , it is thus necessary to collect environmental information during a period long enough to be meaningful. That is, the schedule information may be modified only when it is determined that the ambient environment of the air conditioning apparatus 100 will continue to remain changed in the future.
the air conditioning apparatus 100 is set to operate in a cooling (strong) mode from 9 o'clock to 6 o'clock.
the air conditioning apparatus 100 continues to operate according to the schedule information in an event where there are no persons around the air conditioning apparatus 100 after 12 o'clock p.m., energy will be wasted. This is because the air conditioning apparatus 100 may perform the predetermined operation even though there are no persons from 12 o'clock to 6 o'clock.
the processor 140 may not modify the previously stored schedule information. It may not be preferable that the processor 140 modifies the schedule information while immediately reflecting a measurement in an exceptional situation in the environmental information. Accordingly, the disclosure provides a solution to the above-described problem without modifying the schedule information.
the processor 140 may control an operation of the driver 110 on the basis of the collected environmental information rather than the schedule information.
the processor 140 may control the driver 110 such that the air conditioning apparatus 100 operates in a new state in which the currently collected environmental information is reflected, rather than operating according to the contents included in the schedule information. For example, it is assumed that the air conditioning apparatus 100 is set to operate in a cooling (strong) mode from 9 o'clock to 6 o'clock. However, in an event where there are no persons around the air conditioning apparatus 100 after 12 o'clock p.m., even though the operation state included in the schedule information is indicated as a cooling (strong) mode, the processor 140 may cancel this and control the air conditioning apparatus 100 to be stopped.
the processor 140 may control the air conditioning apparatus 100 on the basis of body temperatures of persons measured by the sensor 120 .
the air conditioning apparatus currently operates in a cooling (weak) mode from 9 o'clock a.m. to 6 o'clock p.m.
the schedule information applied is set such that the air conditioning apparatus 100 operates in a cooling (weak) state at all times.
an operation for quickly lowering an indoor temperature may be necessary, unlike a predicted load.
the processor 140 may ascertain the number of persons as four and ascertain body temperatures of the persons as 40 degrees, and then calculate a load value in which such information is reflected. When a difference between the calculated load value and the already predicted load value is a predetermined value or more, the processor may cancel the schedule information as previously applied, i.e. the cooling (weak) mode, and control the air conditioning apparatus 100 to operate in a cooling (strong) mode.
the processor 140 may ascertain a body temperature for each person, and control the air conditioning apparatus 100 to direct cooling toward a person whose body temperature is highest.
the person whose body temperature is highest is mentioned in a general way, but it is not a requirement that only one person should be involved. While persons are classified into some groups based on their locations, the processor 140 may control the air conditioning apparatus 100 to direct wind toward a group to which high-temperature persons belong in a largest number.
the processor 140 may include a random-access memory (RAM), a read-only memory (ROM), a central processing unit (CPU), a graphic processing unit (GPU), and a bus.
RAM random-access memory
ROM read-only memory
CPU central processing unit
GPU graphic processing unit
the RAM, ROM, CPU and GPU may be connected to each other via the bus.
the air conditioning apparatus 100 is controlled using schedule information classified in time units. Thus, a user does not need to control the air conditioning apparatus 100 every time and the convenience of the user can be improved.
the schedule information is modified on the basis of the collected environmental information and the modified schedule information is reflected in controlling the air conditioning apparatus 100 . Therefore, the disclosure makes it possible to automatically control the air conditioning apparatus 100 without requiring a user to input an operation state of the air conditioning apparatus 100 in person to be suitable for a personal environment, thereby improving the convenience of the user.
the air conditioning apparatus 100 performs an operation of modifying schedule information when the environmental information is analyzed to be in a different pattern from the schedule information that is basically applied.
the processor 140 may predict a future situation by comparing environmental information collected for a predetermined time with existing schedule information. In addition, if the predicted situation is different from the existing schedule information, the processor 140 may modify the existing schedule information, thereby making it possible to efficiently managing the air conditioning apparatus 100 .
the air conditioning apparatus 100 may cope with an exceptional situation without modifying the existing schedule information.
the processor 140 may compare environmental information measured by the sensor with schedule information currently applied to the air conditioning apparatus 100 . When an exceptional situation occurs in which there is a great difference between the two values of the compared information, the processor 140 may recognize the situation.
the driver 110 may be controlled to cancel the schedule information previously applied to the air conditioning apparatus 100 such that the air conditioning apparatus 100 operates in a state corresponding to the collected environmental information.
the air conditioning apparatus 100 may quickly cope with an exceptional situation without modifying the existing schedule information, thereby efficiently managing power of the air conditioning apparatus 100 .
a user does not need to control the air conditioning apparatus 100 separately in an exceptional situation, thereby improving the convenience of the user.
the air conditioning apparatus 100 may predict a future change in environmental information in advance and operate while reflecting the predicted change.
the air conditioning apparatus 100 may operate in advance, while predicting in advance that there will be an increase in the number of persons.
the air conditioning apparatus 100 operating based on the predicted schedule information makes it possible to maintain a comfortable temperature at all times.

IR infrared
Bluetooth remote control or the like.
the remote control is not limited to the above-described kinds of remote controls, and various types of remote controls may be used in the control method according to the disclosure.
the local controller 200 may refer to a user terminal device capable of communicating with the air conditioning apparatus 100 , rather than a remote control.
the user terminal device may be a smart phone, a tablet, or the like.
the user terminal device is not limited thereto, and may be a user terminal device capable of conveying a command regarding a control operation to the air conditioning apparatus 100 , analyzing environmental information, and generating or modifying schedule information, at each predetermined time.
the remote controller may refer to a device capable of controlling the air conditioning apparatus 100 at a long distance rather than at a short distance.
the remote controller may be the cloud server 300 connected to the air conditioning apparatus 100 .
the cloud server 300 may perform the operations of conveying a command regarding a control operation to the air conditioning apparatus 100 , analyzing environmental information, and generating or modifying schedule information, at each predetermined time, and may transmit the result thereof to the air conditioning apparatus 100 .
the air conditioning apparatus 100 may receive a control command from the cloud server 300 every hour and perform a corresponding operation.
the automatic control server 400 may communicate with the air conditioning apparatus 100 .
the external automatic control server 400 may perform the operations of conveying a command regarding a control operation to the air conditioning apparatus 100 , analyzing environmental information, and generating or modifying schedule information, at each predetermined time, and may transmit the result thereof to the air conditioning apparatus 100 .
the schedule information may be a set of control commands in which collected environmental information and information on operation states corresponding to the environmental information are arranged to correspond to time. For example, in schedule information on a daily basis, commands set to perform specific operations at specific times from morning to evening may be stored. Therefore, when the schedule information is applied to the air conditioning apparatus 100 , the processor 140 may automatically control the air conditioning apparatus 100 even though the user does not personally control the air conditioning apparatus 100 .
the schedule information may include environmental information stored for each hour and an operation state of the air conditioning apparatus 100 based on the environmental information.
the environmental information may include at least one of an indoor temperature, an outdoor temperature, a humidity, the number of persons in an air conditioning target, temperatures of the persons, or an amount of dust.
the environmental information may be collected or measured by the sensor 120 .
the operation state may include information on operation modes and output intensities.
the operation modes may refer to different modes such as cooling, heating, blowing and air cleaning functions
the output intensities may refer to different outputs in the same operation mode, such as cooling (strong), cooling (medium), and cooling (weak).
the operation state is not limited to the operation modes and the output intensities, and may additionally include information on functions and operations.
the operation modes and the output intensities are not limited to the above-described elements, and may include additional functions.
the operation state may correspond to collected environmental information.
the processor 140 should analyze the collected environmental information and set an operation state corresponding thereto.
the collected environmental information is very diverse, and thus, the process of reflecting the diverse environmental information may be very complicated.
a machine learning method may be used as one way, which will be described later with reference to FIG. 11 .
the air conditioning apparatus 100 may use the concept of load.
the load may refer to a thermal load that has an influence on controlling a temperature. For example, it is assumed that a current temperature is 30 degrees, and a target temperature is 25 degrees, under the condition that the performance of the air conditioning apparatus 100 is constant.
the air conditioning apparatus 100 needs to operate longer to reach the target temperature when a load is high than when the load is low. That is, it takes a long time to reach the target temperature if the load is high, and it takes a short time to reach the target temperature if the load is low.
the air conditioning apparatus 100 may determine whether to increase an output according to a change in load. For example, if the target temperature of the air conditioning target is 25 degrees at all times, the output is also set to be high at a high-load time, thereby maintaining the target temperature.
the load may refer to various information that having an influence on the time for reaching the target temperature.
the load is used to refer to one representative value in which various environmental information are combined, rather than each information.
the load may be a value calculated by reflecting at least one of an indoor temperature, an outdoor temperature, a humidity, the number of persons in an air conditioning target, body temperatures of the persons, or an amount of dust.
one load value may be calculated through a conversion process corresponding to each information.
the load may be 35.
Each of the assigned numerical values may be changed according to user's settings.
the operation state for each time zone in the schedule information may be modified on the basis of the predicted load for each time zone. As in the above-described example, it is assumed that the current number of persons is 30 and the current temperature is 27 degrees. Here, the predicted load is 35 and an operation state may be determined to correspond to the load value of 35. The operation state may be set to a cooling (strong) mode, and the operation state corresponding to the load value of 35 may be changed according to user's settings.
a load may be predicted and determined by combining a plurality of environmental information, not based only on information at a current time. For example, when it is assumed that a load at 9 o'clock today is 35 and a load at 9 o'clock tomorrow is 30, a load the day after tomorrow may be predicted to be 32.5, which is an average value of 35 and 30.
a predicted load value may be determined through various mathematical methods.
a load obtained in this manner may have a different value depending on time, which will be described in detail below with reference to FIGS. 4 to 7 .
FIGS. 4 to 7 are diagrams for explaining an amount of change in load depending on time according to an embodiment of the disclosure.
FIG. 4 is a diagram for explaining an amount of change in load relative to time according to an embodiment of the disclosure.
the load has a constant value from 9 o'clock to 6 o'clock, and the load at the other times is 0.
the load is kept constant, not adjusting a range of fluctuation in the load over time. Therefore, the schedule information reflecting this may enable the air conditioning apparatus 100 to be set to operate with a constant output from 9 o'clock to 6 o'clock.
FIG. 4 may be relevant to a pattern of load, and the pattern of load may show a change in load over time.
the schedule information reflecting FIG. 4 may be set as basic schedule information.
the schedule information should be set as the simplest one because there is no data stored. Therefore, the schedule information reflecting FIG. 4 may be set as basic schedule information.
an operation start time and an operation end time of the air conditioning apparatus 100 at which the load is changed i.e. 9 o'clock and 6 o'clock, may be changed.
FIG. 5 is a diagram for explaining an amount of change in load according to another embodiment of the disclosure.
FIG. 6 is a diagram for explaining an amount of change in load according to another embodiment of the disclosure.
FIG. 6 it corresponds to a situation opposite to that of FIG. 5 .
it may correspond to a space having a high load between 12 o'clock and 1 o'clock and a low load at the other times. It may correspond to a case such as a restaurant where a load is high only during a lunch time.
it may correspond to a situation from 12 o'clock to 1 o'clock where the persons go out as in FIG. 5 and move to the space corresponding to FIG. 6 .
a load at a time other than 12 o'clock to 1 o'clock is not indicated as zero (0) because there are workers working in the restaurant.
the load at a time other than 12 o'clock to 1 o'clock may be zero (0).
FIGS. 4 to 6 illustrate graphs in which the amount of load is changed instantaneously.
the load may be measured on an hourly basis.
FIG. 7 is a diagram for explaining an amount of change in load according to another embodiment of the disclosure.
FIG. 7 it is illustrated that a measurement cycle is shortened to check that the load increases at a certain speed.
the load is measured on an hourly basis. If the measurement duration is shortened, however, a slope concerning the amount of change in load can be seen as in FIG. 7 .
FIG. 7 there may be no regularity depending on time.
a certain pattern is shown from 9 o'clock a.m. to 6 o'clock p.m., but in FIG. 7 , increases and decreases are repeated without having a certain pattern.
the processor 140 may apply general schedule information as in FIG. 4 .
the air conditioning apparatus 100 may be controlled according to an average value of loads that are changed at a certain time.
FIGS. 4 to 7 described above illustrate a change in load value depending on time, the load value being converted from environmental information varying depending on time (e.g., a temperature or the number of persons).
the change in load value may be calculated through the environmental information collected by the sensor 120 .
the environmental information may include spatial information, temporal information, and person information.
the spatial information may be a size, a form, a purpose of use, a degree of outdoor air blocking, and a degree of air tightness of an air conditioning target.
the size of the air conditioning target may refer to a wideness or a volume
the form of the air conditioning target may be a structural shape such as a rectangle or a circle.
the purpose of use of the air conditioning target may be a working space, sports facilities, performance facilities, a classroom, a hotel, or the like.
the degree of outdoor air blocking and the degree of air tightness may refer to an insulation state of a wall and an openable and closable state of a window or a door.
space A has a wideness of 100 and space B has a wideness of 200, under the same conditions that the air conditioning object is in a square structure and the number of persons is five.
a current temperature is 30 degrees
a target temperature is set to 25 degrees
the same air conditioning apparatus 100 is used for a cooling function with the same output
space B may be predicted to take a longer time to reach the target temperature.
the data on wideness may be converted into a load value.
an increase in wideness causes an increase in load, but they are not considered necessarily proportional. Therefore, actual changes in load depending on the above-described spatial information, such as the form, the wideness, and the purpose of use of the space, may be checked through experiments. Using the correlations ascertained through the experiments, the air conditioning apparatus 100 may convert the measured values of the spatial information into load values. In addition, the above-described correlations may be ascertained on the basis of collected environmental information.
the air conditioning apparatus 100 may ascertain a time for reaching the target temperature by using the converted load values.
the temporal information may be an operation start time and an operation end time of the air conditioning apparatus 100 , an efficient operation-required period for saving energy, and a time when an indoor temperature rapidly rises (or falls). In addition, it may depend on seasons whether to operate the air conditioning apparatus 100 . Thus, the temporal information may include information on seasons.
a load may be added to the temporal information for the period from June to August.
the air conditioning apparatus 100 may perform an operation of adding +20 to a load value for the period from June to August.
the person information may include the number of persons, temperatures of the persons, a density of the persons, an activity of the persons, a clothing amount, an age, a race (or a nationality or a country), and user-specified setting records.
the persons may refer to people who are present in an air conditioning target, and the density of the persons may refer to the number of persons relative to a wideness of the air conditioning target.
the ascertainment of the activity of the persons may refer to ascertaining if the persons in the air conditioning target are stationary or moving. If the persons are moving for a certain time, the air conditioning apparatus 100 may ascertain that they are exercising. Here, it may be predicted in advance that the persons will feel hot soon, and the processor 140 may increase an output of the air conditioning apparatus 100 in advance.
FIGS. 8 to 10 are diagrams for explaining an operation of collecting environmental information according to an embodiment of the disclosure.
FIG. 8 is a diagram for explaining a state where there are persons in an air conditioning target 800 where the air conditioning apparatus 100 operates.
the air conditioning apparatus 100 may determine the number of persons in the air conditioning target 800 using the sensor 120 .
the persons are expressed as being irregularly located, but the sensor 120 may ascertain the number of persons even if the persons are present in a regular form. For example, the number of persons may be ascertained even in a space where a density of persons is very high.
FIG. 9 is a diagram for explaining a movement of a person according to another embodiment of the disclosure.
the air conditioning apparatus 100 may determine a change in the number of persons in the space of the air conditioning target 800 using the sensor 120 .
the sensor 120 may detect a movement of the person, and thus ascertain a change in the number of persons in the space of the air conditioning target 800 .
the air conditioning apparatus 100 may ascertain the change in the number of persons by checking the number of persons who are currently present in the air conditioning target 800 at each predetermined time instead of detecting the movement of the person.
the load reflects environmental information varying depending on time, but may reflect environmental information that does not vary depending on time. For example, it may be spatial information. Normally, once the air conditioning apparatus 100 is installed, its location is rarely changed, and thus, the air conditioning target 800 is not changed depending on time. That is, the air conditioning target 800 of the air conditioning apparatus 100 once installed, i.e. an office or a classroom, has a constant area, a load reflecting this may be constant.
FIGS. 8 to 9 illustrate a form 800 in which the air conditioning target 800 have right-angled corner portions, but the sensor 120 may also detect a form of an air conditioning target having curved corners.
FIG. 10 is a diagram for explaining an air conditioning target according to another embodiment of the disclosure.
the sensor 120 of the air conditioning apparatus 100 may detect a form of an air conditioning target. Referring to FIG. 10 , even when the air conditioning target is not in a general rectangle structure, a specific form may be detected using the sensor 120 .
the sensor 120 may detect a space having an unusual form 900 as illustrated in FIG. 10 .
FIG. 11 is a diagram for explaining a learning model according to an embodiment of the disclosure.
load information may be calculated by a machine learning-based recognition system.
a deep learning-based recognition system is described as an example of a classification system using a series of machine learning algorithms based on neural networks.
the deep learning-based recognition system may include at least one classifier.
the classifier may correspond to one or a plurality of processors 140 .
the processor 140 may be implemented as an array of multiple logic gates, or implemented as a combination of a general-purpose microprocessor 140 and a memory 130 storing a program that may be executed in the microprocessor 140 .
the classifier may be implemented as a neural network-based classifier, a support vector machine (SVM), an adaboost classifier, a Bayesian classifier, a perceptron classifier, and the like.
SVM support vector machine
An embodiment of the disclosure in which the classifier is implemented as a convolutional neural network (CNN)-based classifier will be described below.
the neural network-based classifier which is an arithmetic operation model implemented to emulate a calculation ability of a biological system by using numerous artificial neurons connected by connection lines, performs a cognitive function or a learning process of a human through the connection lines having connection intensities (weights).
the classifier of the disclosure is not limited thereto, and may be implemented as any of the various classifiers described above.
a general neural network includes an input layer 1110 , a hidden layer 1120 , and an output layer 1130 .
the hidden layer 1120 may include one or more layers depending on the need.
a back propagation algorithm may be used as an algorithm for training the neural network.
the classifier may train the neural network such that if certain data is input to the input layer 1110 of the neural network, output data with respect to the input learning data is output to the output layer 1130 of the neural network. If feature information extracted from a captured image is input, the classifier may classify patterns of the feature information into any one of the various classes by using the neural network and output the result of classification.
the input layer 1110 may be a data value measured by the sensor 120 .

the example of the input layer 1110 described above is only for illustrative purposes, and is not limited thereto. That is, the number of nodes of the input layer 1110 may be changed according to user's settings.
the nodes 1111 , 1112 and 1113 of the input layer 1110 are illustrated in three types, but this may be changed.
Data received through the sensor 120 may correspond to the input layer 1110 .
the output layer 1130 may be an output intensity of the driver 110 or an operating mode of the driver 110 .
the processor 140 may determine an operation mode or an output intensity of the driver 110 , which are included in the schedule information, through various data received from the sensor 120 .
the processor 140 may learn based on whether or not power consumption according to the operation mode or the output intensity of the driver 110 is appropriate. In the learning process, a time for reaching a target temperature may also be considered. The processor 140 may learn while considering the time for reaching the target temperature with the operation mode or the output intensity of the driver 110 obtained as an output value.
the output layer 1130 may be set as a load in that the operation mode or the output intensity may vary depending on a size of the load.
the processor 140 needs to calculate an output value for ultimately controlling the driver 110 on the basis of the data received from the sensor 120 .
the processor 140 may use a deep learning-based recognition system as a classification system using a series of machine learning algorithms based on neural networks.
the hidden layer 1120 is expressed to include two stages in FIG. 11 , the classification system may include only one-stage hidden layer. In addition, the number of nodes included in the hidden layer 1120 may also be changed.
FIGS. 12 to 17 are diagrams for explaining schedule information.
FIG. 12A is a diagram for explaining a change in load depending on time.
a plurality of loads 1210 are classified into, load # 1 1211 , load # 2 1212 , and load # 3 1213 on a daily basis.
Times are classified on an hourly basis, and a load varies depending on the classified time 1220 .
loads from 9 o'clock to 12 o'clock among load # 1 1211 are 30.
Load # 1 1211 , load # 2 1212 , and load # 3 1213 refer to load information on a daily basis.
a load value is stored for each hour on a daily basis.
FIG. 12B is a diagram for explaining an operation state of the air conditioning apparatus 100 corresponding to the load.
operation state # 1 1231 , operation state # 2 1232 , and operation state # 3 1233 refer to operation state information on a daily basis.
An operation state value is stored for each hour 1240 on a daily basis.
the times illustrated in FIG. 12B are set on an hourly basis starting from 45 minutes.
the operation state refers to an operation function of the air conditioning apparatus 100 , and the load may have an influence on determining an operation state.
the processor 140 makes it possible to maintain an appropriate target temperature by enabling the air conditioning apparatus 100 to operate in advance with respect to the load depending on time.
the operation state may be applied 15 minutes earlier than the time for which the load value is measured.
15 minutes is one value for explanation and may be changed according to user's settings.
the processor 140 may automatically calculate and apply an optimal operation time for efficient power management even in the absence of the user's manual settings.
the operation state may include information on operation modes and output intensities.
the operation modes may refer to different modes such as cooling, heating, blowing and air cleaning functions
the output intensities may refer to different outputs in the same operation mode, such as cooling (strong), cooling (medium), and cooling (weak).
the operation state is not limited to the operation modes and the output intensities, and may additionally include information on functions and operations.
the times 1220 described in FIG. 12A and the times 1240 described in FIG. 12B are set at one-hour intervals, but this is merely an example and an time interval may be set on a 15-minute basis. Rather, the time interval may be set small to express both load information and operation state information.
FIG. 12C is a diagram for explaining one schedule information including both load information and operation state information.
the schedule information may include environmental information and an operation state, and a load may be calculated on the basis of the environmental information. That is, the schedule information may include both the load and the operation state.
FIG. 12C it illustrates partial schedule information # 1 1250 including both loads 1221 (in FIG. 12 a ) from 8 o'clock to 10 o'clock among load # 1 1211 and operation states 1241 (in FIG. 12 b ) from 7:45 to 9:45 among operation state # 1 1231 (in FIG. 12 b ).
load # 1 1211 and operation state # 1 1231 are stored at the times 1260 that are classified on a 15-minute basis.
the load is zero (0) before 9 o'clock and is 30 from 9 o'clock.
the air conditioning apparatus 100 needs to operate in advance in an air conditioning target having a load of 30 from 9 o'clock. This is because a user may already feel hot if the air conditioning apparatus 100 starts to operate from 9 o'clock, at which the load becomes 30.
the operation state of the air conditioning apparatus 100 may be changed to a cooling (strong) mode 15 minutes earlier than the point-in-time when the load becomes 30.
the operation state may be changed to a cooling (medium) mode.
an operating mode may be set to a cooling mode and an output intensity may be set to a strong intensity to reach a target temperature. To maintain the target temperature after a certain time, however, the output intensity may be set to a medium intensity.
FIG. 13 is a diagram for explaining that a next load is predicted by combining individual load # 1 1211 , load # 2 1212 , and load # 3 1213 illustrated in FIG. 12A .
load # 1 1211 , load # 2 1212 , and load # 3 1213 have different load values from 12 o'clock to 1 o'clock, while having the same load value in the other time zones.
1310 is a graph for load # 1 1211
1320 is a graph for load # 2 1212
1330 is a graph for load # 3 1213 .
1340 is a graph in which load # 1 1211 , load # 2 1212 , and load # 3 1213 are all combined to predict a next load value.
the next load value is predicted as an average value of load # 1 1211 , load # 2 1212 , and load # 3 1213 .
a load value between 12 o'clock and 1 o'clock is 0 for load # 1 1211 , 5 for load # 2 1212 , and 25 for load # 3 1213 .
FIG. 14 is a table illustrating only load values among schedule information.
a load value may only reflect the number of persons.
the sensor 120 may measure the number of persons depending on time. After ascertained, the measured number of persons may be converted into a corresponding load value and stored for each hour.
loads are shown to be changed on an hourly basis in a weekly cycle.
times are classified on an hourly basis, and load information may be seen based on the classified times 1420 for each day of the week, i.e. Monday 1411 . Tuesday 1412 , Wednesday 1413 , Thursday 1414 , Friday 1415 , Saturday 1416 and Sunday 1417 .
the air conditioning target may be a classroom or an office where there are no person on the weekend.
loads are zero (0) before 9 o'clock a.m. and after 6 o'clock p.m.
the air conditioning apparatus 100 may be controlled not to operate.
Most loads from 9 o'clock a.m. to 12 o'clock p.m. are indicated as 30. This may mean that a load value concerning the number of persons is 30.
load values from 9 o'clock a.m. to 12 o'clock p.m. for Thursday may be set to 29 ( 1430 ), which means that one person is unusually absent in the air conditioning target. For example, when a person is not present in the air conditioning target at a specific time because he/she is on a business trip or is late, this may be ascertained through the sensor 120 .
a load is expressed as 5 indicating that most of the persons are out of the air conditioning target and only some of the persons remain there ( 1440 ).
the load from 12 o'clock to 13 o'clock may be set to 5.
the persons After 13 o'clock, the persons returns to the air conditioning target and a load value may be set back to 30.
loads from 14 o'clock to 15 o'clock for Tuesday and Thursday are indicated as 1 ( 1450 ). This is based on the assumption that most persons are not present in the air conditioning target because they are in a physical education class on a specific day of the week. Here, a situation is reflected where only one person remains there, and a load may actually be zero (0) or more than 1. In general, a physical education for a class is carried out at a fixed time on a weekly basis. Thus, load values from 14 o'clock to 15 o'clock for next Tuesday and Thursday may be similar.
the processor 140 may issue a control command corresponding to the schedule information. For example, an output of the air conditioning apparatus 100 may be lowered before 14 o'clock on Tuesdays and Thursdays to avoid wasting unnecessary power.
loads may be 10 from 16 o'clock to 18 o'clock on Monday and Wednesday ( 1460 ), but may be zero (0) on Tuesday, Thursday and Friday. It is reflected that a class ends at 16 o'clock regularly and there is no person in the air conditioning target thereafter, but on Monday and Wednesday a few people remain in the space for other activities from 16 o'clock to 18 o'clock.
Load values may be stored while reflecting information on the air conditioning target of the air conditioning apparatus 100 .
the stored load values may be reflected in schedule information through the processor 140 .
the schedule information may include a control command for operating the air conditioning apparatus 100 from 8:45 a.m., with the prediction that the load rapidly increases to 30 at 9 o'clock a.m.
the schedule information may also include a command for stopping the operation of the air conditioning apparatus 100 from 11:45, with the prediction that the load decreases to 5 at 12 o'clock.
the schedule information may include a control command for operating the air conditioning apparatus 100 at 12:45 in advance, with the prediction that the load rapidly increases back to 30 from 13 o'clock.
the schedule information may include a control command for changing the operation mode of the air conditioning apparatus 100 to a low-output mode from 15:45, with the prediction that the load decreases back to 10 at 16 o'clock.
the control unit may include a control command to stop the operation mode of the air conditioning apparatus 100 from 17:45, with the prediction that the load becomes zero (0) after 18 o'clock.
the time at which the load is changed is expressed as each hour on the hour such as 9, 12, 16, or 18 o'clock, and it is assumed that the air conditioning apparatus 100 performs an operation corresponding to a control command 15 minutes before each hour on the hour.
the load may be changed at a certain time interval, not every hour on the hour, depending on a time when the load is measured. For example, when loads are measured on a 30-minute basis, the loads at 8:30, 9 o'clock, and 9:30 may be stored, and the schedule information may include a control command corresponding to the 30-minute interval.
the operation of the air conditioning apparatus 100 is controlled 15 minutes before the time when the load is changed, but this time may be changed.
the processor 140 may calculate a control command for reaching a target temperature using minimum power for efficient power management without maximizing the performance of the air conditioning apparatus 100 .
a control command for reaching a target temperature using minimum power for efficient power management without maximizing the performance of the air conditioning apparatus 100 .
the target temperature may be reached in 5 minutes with a strong output intensity of cooling.
the target temperature may be reached in 15 minutes with a weak output intensity of cooling.
a time for reaching the target temperature may be calculated using a current temperature and a current load.
the processor 140 may perform such control as to compare power consumptions for operation in the first method and in the second method to select a more efficient method.
FIG. 14 illustrates an embodiment in which the number of persons is only reflected in the load, but it is possible to reflect load information depending on time and a special situation, as well as the number of persons, in the load. Such an embodiment will be described below with reference to FIG. 15 .
FIG. 15 is a diagram illustrating load information on a weekly basis according to another embodiment of the disclosure.
loads may increase by about +10 at 13 o'clock to 15 o'clock on Monday to Friday. From 13 o'clock p.m. to 15 o'clock p.m., a large amount of heat is introduced from the outside, so it takes a longer time to lower a temperature than in the other time zones. To reflect this point, a load value may thus be additionally reflected from 13 o'clock to 15 o'clock and the load is expressed as 40 ( 1510 ).
loads at 15 o'clock on Tuesdays and Thursdays are different by twice when compared to those at 15 o'clock on the other days of the week. This is based on the assumption that persons get back after physical activities from 14 o'clock to 15 o'clock on Tuesday and Thursday. When the persons get back after the physical activities, persons' body temperatures may be high and the persons may feel very hot.
the load reflecting this situation is expressed as 60 ( 1520 ).
This change is repeated on a weekly basis. Thus, it may be checked if an indoor temperature has repeatedly increased at a specific time using the stored data. If the rising pattern has been repeatedly shown by a predetermined number of times or more, a load may be raised and the raised load may be stored as in FIG. 15 . After the load is changed, the schedule information may be generated or modified while reflecting the change.
the schedule information may correspond to a combination of control commands for the air conditioning apparatus 100 to analyze data stored for a certain period and perform corresponding operations depending on time.
the schedule information is changed according to a change in the stored load, but it is general that the schedule information once applied basically remain unchanged.
an embodiment of the disclosure may include an operation of changing the applied schedule information.
FIG. 16 is a diagram for comparing a load 1610 corresponding to the applied schedule information and a currently measured load 1620 .
loads from 9 o'clock a.m. to 12 o'clock p.m. are measured to be the same as those currently applied. However, loads after 12 o'clock p.m. are indicated as zero (0). If the air conditioning apparatus 100 continues to operate to correspond to the applied schedule information in spite of the change in load, power will be wasted much. Of course, this is solved if a user turns off the power when leaving, but an object of the disclosure is to automatically control the air conditioning apparatus 100 . Thus, the disclosure provides a solution thereto.
the processor 140 may calculate a difference value between the load 1610 to which the schedule information is applied and the measured load 1620 .
the processor 140 may determine whether or not the difference value corresponds to a predetermined condition. When the difference value is greater than a certain value, the processor 140 may apply schedule information reflecting a new control command instead of the existing schedule information.
the load values 1620 measured after 12 o'clock are maintained as zero (0) in FIG. 16 .
the previous loads 1610 are also low from o'clock 12 to 1 o'clock, and the processor 140 may not apply new schedule information.
the difference from the previously loads 1610 is great, which corresponds to the predetermined condition, and the processor 140 may not apply the existing schedule information.
an output intensity of the driver 110 may be regulated without applying the existing schedule information.
FIG. 17 is a diagram for explaining modification or generation of schedule information.
a new load pattern 1710 may be generated as illustrated in FIG. 17 .
the existing schedule information may be modified or a new schedule information may be generated.
FIG. 18 is a flowchart for explaining a control method of the air conditioning apparatus 100 according to an embodiment of the disclosure.
a predetermined function of the air conditioning apparatus 100 may be performed on the basis of schedule information (S 1810 ).
the control method may further include previously storing a plurality of schedule information for each day of the week in the air conditioning apparatus 100 .
the predetermined function of the air conditioning apparatus 100 may be performed on the basis of schedule information corresponding to a current day of the week among the plurality of schedule information.
the predetermined function of the air conditioning apparatus 100 may be performed on the basis of initial schedule information selected by a user among a plurality of initial schedule information as previously stored.
the predetermined function may be performed on the basis of the collected environmental information rather than the schedule information.
ambient environmental information of the air conditioning apparatus 100 may be collected (S 1820 ), and the collected ambient environmental information may be stored (S 1830 ).
the environmental information may include at least one of an indoor temperature, an outdoor temperature, a humidity, the number of persons in an air conditioning target, or an amount of dust.
the schedule information may be modified based on environmental information collected during a predetermined period (S 1840 ).
the schedule information may be modified by classifying the collected environmental information as stored for each time zone and comparing the classified environmental information for each time zone with an operation state for each time zone in the schedule information.
a load for each time zone may be predicted on the basis of the classified environmental information for each time zone, and the operation state for each time zone in the schedule information may be modified on the basis of the predicted load for each time zone.
the operation state for each time zone may be predicted from the classified environmental information for each time zone using a predetermined learning model, and the operation state for each time zone in the schedule information may be modified by determining an operation mode of the air conditioning apparatus 100 and an output intensity in the operation mode for the time zone on the basis of the predicted load for the each time zone.
the operation state for each time zone in the schedule information may be modified on the basis of the predicted load for each time zone and spatial information of an air conditioning target.
the air conditioning apparatus 100 is controlled using the schedule information classified in time units.
the user does not need to control the air conditioning apparatus 100 every time and the convenience of the user can be improved.
the schedule information is modified on the basis of the collected environmental information and the modified schedule information is reflected in controlling the air conditioning apparatus 100 . Therefore, it is possible to automatically control the air conditioning apparatus 100 without requiring the user to control an operation state of the air conditioning apparatus 100 to be suitable for an personal environment, thereby improving the convenience of the user.
the air conditioning apparatus 100 performs an operation of modifying schedule information when the environmental information is analyzed to be in a different pattern from the schedule information that is basically applied.
the processor 140 may predict a future situation by comparing environmental information collected for a predetermined time with existing schedule information. In addition, if the predicted situation is different from the existing schedule information, the processor 140 may modify the existing schedule information, thereby making it possible to efficiently manage the air conditioning apparatus 100 .
the air conditioning apparatus 100 may cope with an exceptional situation without modifying the existing schedule information.
the processor 140 may compare environmental information measured by the sensor with schedule information currently applied to the air conditioning apparatus 100 . When an exceptional situation occurs in which there is a great difference between the two values of the compared information, the processor 140 may recognize the situation.
the driver 110 may be controlled to cancel the schedule information previously applied to the air conditioning apparatus 100 such that the air conditioning apparatus 100 operates in a state corresponding to the collected environmental information.
the air conditioning apparatus 100 may quickly cope with an exceptional situation without modifying the existing schedule information, thereby efficiently managing power of the air conditioning apparatus 100 .
the user does not need to control the air conditioning apparatus 100 separately in an exceptional situation, thereby improving the convenience of the user.
the air conditioning apparatus 100 may predict a future change in environmental information in advance and operate while reflecting the change.
the air conditioning apparatus 100 may operate in advance, while predicting in advance that there will be an increase in the number of persons.
the air conditioning apparatus 100 operating based on the predicted schedule information makes it possible to maintain a comfortable temperature at all times.
