BACKGROUND

1. Field

The disclosure relates to an electronic apparatus and a controlling method thereof, and more particularly, to an electronic apparatus controlling an Internet of Things (IoT) network, and a controlling method thereof.

2. Description of Related Art

A plurality of home appliances included in an IoT network may be registered in a server in advance. To control the plurality of home appliances registered in the server, a user may directly use a terminal apparatus. The server may register a plurality of home appliances in advance, and transmit control signals to the registered home appliances based on control commands of the user.

The server may store map information for spaces in which the IoT network is implemented. For example, the server may store information on structures of spaces in which the plurality of home appliances are installed.

However, the information on the spaces stored in the server is merely structural information, and may be information for movements regarding movable apparatuses. Accordingly, in the case of intending to control various home appliances based on the structural information for spaces, there is a problem that the characteristics of each space cannot be reflected. For example, in the case of controlling home appliances uniformly for a space of which use is different or a space that is not ventilated structurally, a problem that the space does not reach an environment that the user wants, or energy efficiency becomes lower may occur.

Also, in the case of applying a predefined set value uniformly to a plurality of home appliances, the set value does not suit the uses of the plurality of respective spaces, and thus a problem that energy is wasted may occur.

In addition, in case a user directly inputs set values or control commands for the plurality of respective home appliances for resolving the aforementioned problems, a problem that the user's convenience is reduced may occur.

In contrast, the user terminal 200 may directly receive information related to the plurality of home appliances 401, 601-1 to 605-2 through the electronic apparatus 100, or receive the information through the AP apparatus 300.

According to another embodiment, the user terminal 200 may directly transmit a user command to the plurality of home appliances 401, 601-1 to 605-2, rather than via the electronic apparatus 100. Here, the user terminal 200 may use the same AP apparatus 300 as the plurality of home appliances 401, 601-1 to 605-2 included in the IoT network 400. For example, the user terminal 200 may transmit the user command to the plurality of home appliances 401, 601-1 to 605-2 through the AP apparatus 300. Then, the user terminal 200 may receive information related to the plurality of home appliances 401, 601-1 to 605-2 through the AP apparatus 300.

That is, the plurality of home appliances 401, 601-1 to 605-2 may be controlled by a user command received from the AP apparatus 300. Here, the user command may be generated by the user terminal 200. The plurality of home appliances 401, 601-1 to 605-2 may be connected with the electronic apparatus 100, and transmit and receive information.

FIG. 2 is a block diagram illustrating an electronic apparatus according to j embodiment of the disclosure.

Referring to FIG. 2, the electronic apparatus 100 may include a memory 110, a communication interface 120, and a processor 130.

The electronic apparatus 100 may be a server that can control the IoT network. The electronic apparatus according to various embodiments of this specification may include, for example, at least one of a desktop personal computer (PC), a laptop PC, a tablet PC, a smartphone, a mobile phone, a personal digital assistant (PDA), or a portable multimedia player (PMP).

The memory 110 may be an internal memory such as a read-only memory (ROM) (e.g., an electrically erasable programmable read-only memory (EEPROM)) and a random access memory RAM included in the processor 130, or may be a separate memory from the processor 130. In this case, the memory 110 may be a memory embedded in the electronic apparatus 100, or a memory that can be attached to or detached from the electronic apparatus 100 according to the use of stored data. For example, in the case of data for operating the electronic apparatus 100, the data may be stored in a memory embedded in the electronic apparatus 100, and in the case of data for an extended function of the electronic apparatus 100, the data may be stored in a memory that can be attached to or detached from the electronic apparatus 100.

In the case of a memory embedded in the electronic apparatus 100, the memory may be implemented as at least one of a volatile memory (e.g., a dynamic RAM (DRAM), a static RAM (SRAM), or a synchronous dynamic RAM (SDRAM), etc.) or a non-volatile memory (e.g., an one time programmable ROM (OTPROM), a programmable ROM (PROM), an erasable and programmable ROM (EPROM), an electrically erasable and programmable ROM (EEPROM), a mask ROM, a flash ROM, a flash memory (e.g., NAND flash or NOR flash, etc.), a hard drive, or a solid state drive (SSD)). Also, in the case of a memory that can be attached to or detached from the electronic apparatus 100, the memory may be implemented as a memory card (e.g., compact flash (CF), secure digital (SD), micro secure digital (Micro-SD), mini secure digital (Mini-SD), extreme digital (xD), a multi-media card (MMC), etc.), an external memory that can be connected to a USB port (e.g., a USB memory), etc.

The memory 110 may store first information on the plurality of home appliances 401, 601-1 to 605-2 included in the IoT network 400, and second information on a plurality of spaces in which the plurality of home appliances 401, 601-1 to 605-2 are located.

Here, the IoT network 400 may include the plurality of home appliances 401, 601-1 to 605-2. Specifically, the plurality of home appliances 401, 601-1 to 605-2 may be registered in the electronic apparatus 100 managing the IoT network 400, and a user may control the plurality of home appliances 401, 601-1 to 605-2 through the electronic apparatus 100.

Here, the first information may be home appliance information. The home appliance information may mean identification information for each of the plurality of home appliances 401, 601-1 to 605-2. Also, the home appliance information may include at least one of identification information of the home appliances, location information of the home appliances, or power efficiency information of the home appliances.

The home appliance information may include at least one of identification information of the home appliances, location information of the home appliances, or power efficiency information of the home appliances.

The communication interface 120 is a component performing communication with various types of external apparatuses according to various types of communication methods. The communication interface 120 includes a Wi-Fi module, a Bluetooth module, an infrared communication module, and a wireless communication module, etc. Here, each communication module may be implemented in the form of at least one hardware chip.

A Wi-Fi module and a Bluetooth module perform communication by a Wi-Fi method and a Bluetooth method, respectively. In the case of using a Wi-Fi module or a Bluetooth module, various types of connection information such as an SSID or a session key is transmitted and received first, and connection of communication is performed by using the information, and various types of information can be transmitted and received thereafter.

An infrared communication module performs communication according to an infrared Data Association (IrDA) technology of transmitting data to a near field wirelessly by using infrared rays between visible rays and millimeter waves.

A wireless communication module may include at least one communication chip that performs communication according to various wireless communication standards such as Zigbee, 3rd Generation (3G), 3rd Generation Partnership Project (3GPP), Long Term Evolution (LTE), LTE Advanced (LTE-A), 4th Generation (4G), 5th Generation (5G), etc.

Other than the above, the communication interface 120 may include at least one of a Local Area Network (LAN) module, an Ethernet module, or a wired communication module that performs communication by using a pair cable, a coaxial cable, an optical fiber cable, or an Ultra Wide-Band (UWB) module, etc.

According to an embodiment, the communication interface 120 may use the same communication module (e.g., a Wi-Fi module) for communicating with an external apparatus like a remote control and an external server.

According to another embodiment, the communication interface 120 may use a different communication module (e.g., a Wi-Fi module) for communicating with an external apparatus like a remote control and an external server. For example, the communication interface 120 may use at least one of an Ethernet module or a Wi-Fi module for communicating with an external server, and use a BT module for communicating with an external apparatus like a remote control. However, this is merely an example, and the communication interface 120 may use at least one communication module among various communication modules in the case of communicating with a plurality of external apparatuses or external servers.

The electronic apparatus 100 may perform communication with various kinds of external apparatuses by using the communication interface 120. Here, external apparatuses may include a display apparatus like a TV, an image processing apparatus like a set-top box, an external server, a control apparatus like a remote control, an audio outputting apparatus like a Bluetooth speaker, a lighting apparatus, a smart bulb, a smart plug, a smart cleaner, a home appliance like a smart refrigerator, a server like an IoT home manager, etc.

The processor 130 may perform overall control operations of the electronic apparatus 100. Specifically, the processor 130 performs a function of controlling the overall operations of the electronic apparatus 100.

The processor 130 may be implemented as a digital signal processor (DSP) processing digital signals, a microprocessor, and a time controller (TCON). However, the disclosure is not limited thereto, and the processor 130 may include one or more of a central processing unit (CPU), a micro controller unit (MCU), a micro processing unit (MPU), a controller, an application processor (AP), a graphics-processing unit (GPU) or a communication processor (CP), and an ARM processor, or may be defined by the terms. Also, the processor 130 may be implemented as a system on chip (SoC) having a processing algorithm stored therein or large scale integration (LSI), or in the form of a field programmable gate array (FPGA). The processor 130 may perform various functions by executing computer executable instructions stored in the memory 110.

If a user command for controlling the first home appliance among the plurality of home appliances 401, 601-1 to 605-2 is received, the processor 130 may identify a first space in which the first home appliance is located based on the first information, identify space information of the identified first space based on the second information, and control the communication interface 120 to transmit a control signal for controlling the first home appliance to the first home appliance based on control information included in the user command and the space information of the identified first space.

Here, a user command may be a command for controlling one home appliance (the first home appliance) among the plurality of home appliances 401, 601-1 to 605-2. Accordingly, when a user command is received, the processor 130 may identify the first space in which the first home appliance corresponding to the user command is located based on identification information for each of the plurality of home appliances 401, 601-1 to 605-2 and location information for each of the plurality of home appliances 401, 601-1 to 605-2.

Here, the processor 130 may identify space information of the identified first space. The space information may mean the unique characteristic information of the space. For example, the space information of the first space may be a kid's room. For a kid's room, an appropriate temperature, appropriate humidity, and appropriate fine dust concentration may exist, and there may be a high need for controlling the room to a different environment from adults. Accordingly, the space information may include information of a content that the first space is a kid's room.

Here, the information included in the user command may mean a driving mode, and target environment data (a target set value) corresponding to the driving mode. Here, if the driving mode is cooling, the target environment data may mean a target temperature, and if the driving mode is dehumidification, the target environment data may mean target humidity, and if the driving mode is air purification, the target environment data may mean target fine dust concentration.

The processor 130 may consider both the control information included in the user command and the space information of the first space stored in advance in the memory 110 in controlling the first home appliance. For example, the processor 130 may identify a subject home appliance, a subject space, a subject driving mode, and target environment data included in the user command. Then, the processor 130 may obtain the pre-stored space information of the first space. Then, the processor 130 may change the target environment data based on the obtained space information of the first space. For example, it is assumed that the user input a command for controlling the first home appliance by setting the temperature to 22 degrees, and the user command was received by the electronic apparatus 100. Here, even though the user command is for controlling the first space including the first home appliance to 22 degrees, the processor 130 may automatically change the target environment data to 25 degrees but not 22 degrees, as the first space falls under a kid's room.

Accordingly, the processor 130 may partially change the control information including the user command based on the space information of the identified first space. Then, the processor 130 may generate a control signal for controlling the first home appliance based on the changed control information. Then, the processor 130 may transmit the generated control signal to the first home appliance through the communication interface 120. Here, the operation of the processor 130 of transmitting the generated control signal to the first home appliance may mean an operation that the generated control signal is transmitted to the first home appliance through the AP apparatus 300.

If a user command for controlling one home appliance is received, the electronic apparatus 100 according to an embodiment may control only the first home appliance corresponding to the user command.

If a user command for controlling one home appliance is received, the electronic apparatus 100 according to another embodiment may control the first home appliance corresponding to the user command and a second home appliance different from the first home appliance together.

Based on the received user command, the processor 130 may identify a second home appliance performing a function related to the first home appliance among the plurality of home appliances 401, 601-1 to 605-2, identify a second space in which the second home appliance is located based on the first information, identify space information of the identified second place based on the second information, and control the communication interface 120 to transmit a control signal for controlling the second home appliance to the second home appliance based on control information included in the user command and the space information of the identified second space.

Here, the function related to the first home appliance may mean a function in an identical technical field or a similar technical field to the first home appliance. For example, if the first home appliance is an air conditioner, the function related to the air conditioner may be cooling, and may be controlling the air. Accordingly, the function related to the air conditioner may mean at least one of cooling, dehumidification, removal of fine dust, or ventilation. Also, the second home appliance performing the function related to the air conditioner may be an air conditioner, a dehumidifier, an air purifier, and a ventilator. Further, the second home appliance may mean a heat exchanger other than the above.

If a user command for controlling the first home appliance located in the first space is received, the processor 130 may generate a control signal for additionally controlling the second home appliance other than the first home appliance. Specifically, the processor 130 may identify the second home appliance performing a function related to the first home appliance near the first space in which the first home appliance is located. Then, the processor 130 may identify the second space based on the location information of the identified second home appliance. Then, the processor 130 may identify space information of the identified second space. Here, the processor 130 may determine how to control the second home appliance based on the user command and the space information of the second space. For example, if the user command is for setting the first space to 22 degrees, the processor 130 may generate a control signal for controlling the second home appliance such that the second space can also be set to 22 degrees, and transmit the generated control signal to the second home appliance.

The processor 130 may simultaneously control the first home appliance and the second home appliance based on the user command for the first home appliance. This is because the first space and the second space are adjacent, and as long as the spaces are not physically divided, it may be difficult to control only the first space to 22 degrees due to air circulation.

If user occupancy information is received, the processor 130 may identify a third space in which the user is located based on the received user occupancy information, and if the first space and the third space are identified as the same space, the processor 130 may control the communication interface 120 to transmit a control signal for controlling the first home appliance to the first home appliance based on control information included in the user command, the space information of the identified first space, and the user's information.

The user occupancy information may mean information indicating whether the user is located in a specific space. The processor 130 may determine whether a space is occupied by the user through at least one home appliance that can determine whether a space is occupied by the user among the plurality of home appliances 401, 601-1 to 605-2 included in the IoT network 400. Specifically, a home appliance including a camera or an object recognition sensor among the plurality of home appliances 401, 601-1 to 605-2 may determine whether a space is occupied by the user. The home appliance that determined whether a space is occupied by the user may transmit the determination result to the electronic apparatus 100.

Here, the processor 130 may obtain the user occupancy information by using a movable auxiliary home appliance 401. Specifically, the auxiliary home appliance 401 may include a camera or an object recognition sensor, and the auxiliary home appliance 401 may determine whether a space is occupied by the user based on data obtained from the camera or the object recognition sensor.

The processor 130 may identify in which space the user is currently located. Also, if the space in which the user is actually located is the same as the space corresponding to the user command, the processor 130 may generate a control signal for controlling the first home appliance based on control information included in the user command, the space information of the first space, or the user's information. Here, the user information may mean the unique characteristic information of the user. For example, in case the user is a kid, characteristic information that the user hates a very cold environment may be stored in the memory 110. Also, if it is identified that a pre-registered kid is occupying the space, the processor 130 may control the home appliance based on the characteristic information of the kid.

Detailed explanation regarding whether a space is occupied by a user will be described below in FIG. 11 and FIG. 12.

The space information may include at least one of the structure information of the plurality of spaces, the arrangement information of the plurality of home appliances 401, 601-1 to 605-2, or the use information of the plurality of spaces.

Here, the structure information may be information indicating in which forms the plurality of spaces are constituted, and in which structures the spaces are divided. Also, the arrangement information of the plurality of home appliances 401, 601-1 to 605-2 may be coordinate information indicating in which locations the home appliances are installed. In addition, the use information of the plurality of spaces may mean information indicating the main uses of the respective spaces. For example, the uses may include at least one of a living room, a kitchen, a bathroom, or a kid's room.

The first home appliance may be an air conditioner, and the processor 130 may control the communication interface 120 to transmit a control signal for controlling at least one of the driving mode, the blowing direction, or the blowing strength of the air conditioner to the air conditioner based on the structure information of the first space.

The first home appliance may be installed in the first space among the plurality of spaces. Here, the processor 130 may automatically control the first home appliance based on the structure information of the first space. The operation of controlling the home appliance based on the structure information may mean determining a detailed control operation based on the size and the structure of the first space after receiving a user command.

For example, it is assumed that the electronic apparatus 100 received a command for the first home appliance to operate in the target temperature 22 degrees. If the size of the first space in which the first home appliance is located is greater than or equal to a threshold value, the processor 130 may determine the first home appliance to ‘a turbo cooling mode,’ determine the blowing direction to ‘moving in up, down, left, and right directions,’ and determine the blowing strength as ‘strong.’

The memory 110 may further store power efficiency information of the plurality of home appliances 401, 601-1 to 605-2, and the processor 130 may identify a space in which a third home appliance of which power efficiency is smaller than or equal to a threshold value is located among the plurality of home appliances 401, 601-1 to 605-2, and identify a fourth home appliance performing a function related to the third home appliance among home appliances located in spaces adjacent to the identified space, and control the communication interface 120 to transmit a control signal for controlling the fourth home appliance to the fourth home appliance based on space information of the identified space and driving state information of the third home appliance.

Here, the power efficiency information may be information indicating how much energy efficiency a home appliance has regarding power that is consumed during a specific time. The processor 130 may identify the third home appliance of which power efficiency is smaller than or equal to the threshold value among the plurality of home appliances 401, 601-1 to 605-2. Then, the processor 130 may identify the space in which the identified third home appliance is located. Then, the processor 130 may identify the fourth home appliance performing a similar function to the third home appliance among home appliances located in spaces adjacent to the identified space.

For example, it is assumed that the power efficiency of the third home appliance located in the third space is smaller than or equal to the threshold value. Accordingly, in the case of making only the third home appliance operate in a general operation, a problem that power consumption increases may occur. Accordingly, the processor 130 may identify the fourth home appliance that is located in an adjacent space to the third home appliance, and can perform a similar function. Here, the fourth home appliance may be a different home appliance from the third home appliance. The processor 130 may complement the third home appliance having low power efficiency by controlling not only the third home appliance, but also the fourth home appliance together.

Detailed explanation related to power efficiency will be described below in FIG. 15.

If it is identified that integrated control with another home appliance other than the first home appliance is needed based on the space information of the first space, the processor 130 may identify a fifth home appliance that is movable and performs a function related to the first home appliance among the plurality of home appliances 401, 601-1 to 605-2, and control the communication interface 120 to transmit a control signal for controlling the fifth home appliance to the fifth home appliance based on the space information of the first space and driving state information of the first home appliance.

Here, integrated control may be additionally controlling another home appliance together, other than a home appliance corresponding to a user command. Here, if the first home appliance is one of an air conditioner, a dehumidifier, an air purifier, a ventilator, or a heat exchanger, the fifth home appliance for integrated control may be one of an air conditioner, a dehumidifier, an air purifier, a ventilator, or a heat exchanger that are movable.

Here, the driving state information may include at least one of a driving mode determined to perform a control operation corresponding to a user command, target environment data (a target set value) corresponding to the driving mode, or current environment data (a sensed value).

Specifically, the fifth home appliance may be the auxiliary home appliance 401, and detailed explanation in this regard will be described below in FIG. 8, FIG. 9, and FIG. 15 to FIG. 19.

The processor 130 may control the communication interface 120 to transmit a control signal for moving the fifth home appliance within a range of a threshold distance from the first space to the fifth home appliance based on the space information of the first space and location information of the fifth home appliance.

If it is determined that integrated control for the first home appliance located in the first space is needed, the processor 130 may transmit a control signal for making the fifth home appliance (the auxiliary home appliance 401) move and perform an auxiliary operation of circulating air. Detailed explanation in this regard will be described below in FIG. 19.

In case the environment data of the first space does not reach the environment data corresponding to the control signal within a threshold time, the processor 130 may determine that integrated control with another home appliance other than the first home appliance is needed.

Detailed explanation in this regard will be described below in FIG. 16.

The processor 130 may control the communication interface 120 to transmit a control signal for moving the fifth home appliance within the range of the threshold distance from the first space to the fifth home appliance based on the space information of the first space and the location information of the fifth home appliance, control the communication interface 120 to transmit a control signal for photographing the first space to the fifth home appliance, and when a photographed image is received from the fifth home appliance, control the communication interface 120 to transmit the received photographed image to a user terminal.

Detailed explanation in this regard will be described below in FIG. 17 and FIG. 20.

The electronic apparatus 100 according to an embodiment of the disclosure may partially change control information included in a user command based on the space information. Accordingly, even if the user does not separately transmit control commands to all spaces, the home appliances included in the plurality of spaces can be automatically controlled based on the information stored in the electronic apparatus 100. Accordingly, the user's convenience can be increased.

Also, as the plurality of home appliances respectively located in the plurality of spaces can be integrally controlled like an IoT network, the user's convenience can be increased.

In addition, in case power efficiency is low or a target value cannot be reached within a threshold time, energy can be saved through the feature of using an auxiliary home appliance.

Further, in case a problem occurs, an auxiliary home appliance can directly move, and then provide image data to the user, and thus the user can resolve the problem easily.

In the above, only simple components constituting the electronic apparatus 100 were illustrated and described, but in actual implementation, various components may additionally be included.

The environment data corresponding to the driving mode may mean a target value according to the driving mode. For example, it may be a target temperature 23 degrees in the cooling mode. The environment data may mean at least one of a target temperature, target humidity, or target fine dust.

The electronic apparatus 100 may identify a space corresponding to the first user command, and identify whether the identified space is stored in advance in the memory 110 of the electronic apparatus 100 in operation S410. Here, the space corresponding to the first user command may mean the space in which the subject appliance included in the first user command is located. For example, the space may mean the first space in which the first home appliance which is the subject appliance of the first user command is located.

In the first user command, subject appliance identification information may be included.

Referring to FIG. 5, the electronic apparatus 100 may receive a first user command in operation S505. Then, the electronic apparatus 100 may identify whether a home appliance corresponding to the first user command is stored in the memory 110 in operation S510. Specifically, in the memory 110, identification information of pre-registered home appliances and location information of the pre-registered home appliances may be stored. Accordingly, the electronic apparatus 100 may determine whether the appliance included in the first user command is pre-registered in the memory 110.

Referring to FIG. 10, the electronic apparatus 100 may store a table of target environment data of each space 1005 and a table of home appliance information of each space 1010.

The table of target environment data of each space 1005 indicates target environment data according to an embodiment, and it may include at least one of identification information, uses, or environment data. A different set value may be set for each space. Here, the target environment data of each space may mean target set values set differently according to spaces. Here, the environment data may include at least one of a temperature, humidity, or fine dust concentration. A user may set target environment data differently for each space. For example, a user may set a room such that the temperature becomes 27 degrees, the humidity becomes 60%, and the fine dust concentration becomes 5 ug/m{circumflex over ( )}3, and at the same time, set the kitchen such that the temperature becomes 24 degrees, the humidity becomes 70%, and the fine dust concentration becomes 60 ug/m{circumflex over ( )}3. Here, each target set value does not need to be input by the user one by one, and the value may be set automatically based on space information.

The electronic apparatus 100 may obtain the target environment data based on weather information and space information. The electronic apparatus 100 may obtain weather information from an external server. Also, the electronic apparatus 100 may obtain space information as obtained in FIG. 4. Here, the space information may include use information of a space. The electronic apparatus 100 may obtain optimal target environment data based on the weather information and the use information. For example, the electronic apparatus 100 may obtain weather information which is the outdoor temperature of 30 degrees, the humidity of 80%, and the fine dust concentration of 30 ug/m{circumflex over ( )}3. Then, the electronic apparatus 100 may identify whether the use of each room is a space for a kid, a space corresponding to the kitchen, etc. Then, the electronic apparatus 100 may determine such that the temperature becomes high for the kid's room, and the temperature is set to be low for the kitchen. As the kid can catch a cold because of a cold temperature, the electronic apparatus 100 may set the temperature higher than other spaces. As the concentration of fine dust generated in a cooking process of food may increase in the kitchen, the electronic apparatus 100 may set the set value of the fine dust concentration to be higher than other spaces for power efficiency.

The table 1010 indicates home appliance information for each space. According to a space, at least one home appliance having identical or different functions may be located. The table 1010 may have summed up home appliance information of each space corresponding to FIG. 9. The home appliance information may additionally include unique identification information of the home appliances.

Referring to FIG. 11, the electronic apparatus 100 may determine whether a space corresponding to the IoT network 400 is occupied by a user in operation S1105. Specifically, the electronic apparatus 100 may use the plurality of home appliances included in the IoT network 400 for identifying whether a user exists in a space corresponding to the IoT network 400. A home appliance including a camera among the plurality of home appliances may determine whether the space is occupied by the user based on a photographed image. Depending on implementation examples, some home appliances may determine whether the space is occupied by the user by using sensing data obtained from an object recognition sensor other than a camera. Specifically, the electronic apparatus 100 may determine whether the space is occupied by the user by using the auxiliary home appliance 401.

Specifically, some home appliances may identify the user's location based on a photographed image or sensing data in operation S1110. Specifically, the electronic apparatus 100 may identify in which space the user is located among the plurality of spaces. Then, the electronic apparatus 100 may generate a control signal for controlling the home appliance included in the space in which the user is located (assumed as the first space), and transmit the generated control signal to the home appliance included in the space in which the user is located in operation S1115. For example, if the user is located in the first space, the electronic apparatus 100 may control at least one home appliance located in the first space. Here, the electronic apparatus 100 may generate a control signal for the at least one home appliance to operate in a specific driving mode and a set value corresponding to the specific driving mode, and transmit the generated control signal to the at least one home appliance.

The electronic apparatus 100 may determine whether a user is located in the first space per predetermined cycle in operation S1120. As the user may move, the electronic apparatus 100 may determine the location of the user per predetermined cycle. If the user is located in the first space (the space in which the user was already identified) without a change, the electronic apparatus 100 may repeatedly perform the operation S1115 and the operation S1120 per predetermined cycle.

However, if the user is not located in the first space (the space in which the user was already identified), the electronic apparatus 100 may generate a control signal for changing the home appliance located in the first space to a power saving mode, and transmit the generated control signal to the home appliance located in the first space in operation S1125. This is because, if the user is not located in the first space, there is no need to perform the operation S1115 anymore. However, in consideration of a situation wherein the user is temporarily out of the first space, the electronic apparatus 100 may perform control such that the home appliance located in the first space operates in the power saving mode, instead of turning off the power completely.

After changing the home appliance located in the first space to the power saving mode by the operation S1125, the electronic apparatus 100 may identify again whether the user is located in the first space during a threshold time in operation S1130. For example, the electronic apparatus 100 may identify whether the user is located in the first space during 10 minutes (the threshold time) right after the home appliance located in the first space was changed to the power saving mode. If the user is identified in the first space within the threshold time, the electronic apparatus 100 may perform the operations S1115 to S1130 again. If the user is not identified in the first space within the threshold time, the electronic apparatus 100 may generate a control signal for turning off the power of the home appliance located in the first space, and transmit the generated control signal to the home appliance located in the first space in operation S1135.

FIG. 12 is a diagram for illustrating an operation related to user occupancy in FIG. 11.

Referring to FIG. 12, the space 800 may be divided into a plurality of spaces, and the electronic apparatus 100 may identify in which space among the respective spaces the user exists by using the auxiliary home appliance 401. Here, the auxiliary home appliance 401 may be a movable apparatus, and it may identify the user through a camera or a sensor. If the auxiliary home appliance 401 performs the operation of determining whether a space is occupied by the user, the auxiliary home appliance 401 may obtain user occupancy information and home appliance information located in the space occupied by the user.

For example, the electronic apparatus 100 may obtain information that the first user 1201 is located in the first space 601, and two home appliances 601-1,601-2 are located in the first space. Also, the electronic apparatus 100 may obtain information that the second user 1202 is located in the second space 602, and two home appliances 602-1,602-2 are located in the second space. In addition, the electronic apparatus 100 may obtain information that the third user 1203 is located in the fourth space 604, and two home appliances 604-1,604-2 are located in the fourth space.

FIG. 13 is a diagram for illustrating an operation of controlling such that a ventilator and a temperature and humidity adjustment apparatus do not operate simultaneously based on driving state information of the ventilator and the temperature and humidity adjustment apparatus.

Referring to FIG. 13, the electronic apparatus 100 may receive a first user command for controlling the first home appliance in operation S1305. Then, the electronic apparatus 100 may generate a control signal for controlling the first home appliance based on the first user command, and transmit the generated control signal to the first home appliance in operation S1310. Then, the electronic apparatus 100 may receive a second user command for controlling the second home appliance in operation S1315.

Here, it is assumed that the first home appliance and the second home appliance are home appliances that cannot be used simultaneously. For example, in case the first home appliance is an air conditioner, and the second home appliance is a ventilator, if the air conditioner and the ventilator are turned on simultaneously, power efficiency may be reduced. Accordingly, the electronic apparatus 100 may store information on home appliances that should not operate simultaneously in the memory 110. For example, an air conditioner and a ventilator, and an air purifier and a ventilator may be home appliances that cannot operate simultaneously with each other.

The electronic apparatus 100 may identify whether the first home appliance and the second home appliance operate simultaneously in operation S1320. Specifically, if it is identified that the first home appliance included in the first user command and the second home appliance additionally received fall under home appliances that cannot operate simultaneously, the electronic apparatus 100 may identify whether the first home appliance and the second home appliance operate simultaneously. After a specific time passed after the first user command for controlling the first home appliance was received, the second user command for controlling the second home appliance is received, and thus the electronic apparatus 100 may identify whether there is a possibility that power efficiency may be reduced as the first home appliance and the second home appliance operate simultaneously, practically through the operation S1320.

In some cases, a situation wherein the first home appliance does not operate at the time point when the second user command was received after a specific time passed may occur. Here, if it is identified that the first home appliance and the second home appliance do not operate simultaneously, the electronic apparatus 100 may generate a control signal for controlling the second home appliance based on the second user command, and transmit the generated control signal to the second home appliance in operation S1325.

If it is identified that the first home appliance and the second home appliance operate simultaneously, the electronic apparatus 100 may provide guide information for controlling only any one home appliance between the first home appliance and the second home appliance to the user in operation S1330. Here, the guide information may mean information guiding the user to select one of the first home appliance or the second home appliance. Specifically, the electronic apparatus 100 may generate guide information, and transmit the generated guide information to the user terminal 200. Then, the user terminal 200 that received the guide information may display the information on the display 240. The user may input a third user command through the user terminal 200. Then, the user terminal 200 may transmit the received third user command to the electronic apparatus 100.

The electronic apparatus 100 may receive the third user command from the user terminal 200 in operation S1335. Then, the electronic apparatus 100 may generate a control signal for controlling the home appliance corresponding to the third user command, and transmit the generated control signal to the home appliance corresponding to the third user command in operation S1340. Here, the home appliance corresponding to the third user command may mean one of the first home appliance or the second home appliance, and may mean the home appliance selected by the third user command.

Then, the electronic apparatus 100 may generate a control signal for turning off the powers of the home appliances not corresponding to the third user command, and transmit the generated control signal to the home appliances not corresponding to the third user command in operation S1345.

For example, if the third user command includes information for controlling the first home appliance, the electronic apparatus 100 may generate a control signal for controlling the first home appliance, and generate a control signal for turning off the power of the second home appliance. Then, the electronic apparatus 100 may transmit the generated control signal to the first home appliance.

FIG. 14 is a table for illustrating an operation of identifying whether integrated control is needed based on environment data for each space.

Referring to FIG. 14, the electronic apparatus 100 may control spaces corresponding to the IoT network 400 with the plurality of home appliances included in the IoT network 400. Specifically, the electronic apparatus 100 may obtain environment data corresponding to the spaces in which the plurality of home appliances are included through the IoT network 400. It is assumed that the environment data described in FIG. 14 is the temperature. The electronic apparatus 100 may obtain the set temperature and the current temperature, and compare the temperatures.

The electronic apparatus 100 may control the plurality of home appliances included in the IoT network 400 based on set values corresponding to the plurality of spaces. The electronic apparatus 100 may compare the set value of each of the plurality of spaces and the sensing value sensed in each of the plurality of spaces after a threshold time passed. Here, if the difference value between the set value and the sensing value is greater than or equal to a threshold value, the electronic apparatus 100 may identify that integrated control for the space is needed. Here, integrated control may mean an operation of controlling the IoT network 400 by additionally using the auxiliary home appliance 401 other than general home appliances.

For example, in the first space, the second space, the third space to the fifth space, the difference between the set value and the sensing value is smaller than or equal to the threshold value, and thus the electronic apparatus 100 may identify that the first space, the second space, the third space to the fifth space are spaces which do not need integrated control. In the fourth space, the difference between the set value and the sensing value is greater than or equal to the threshold value, and thus the electronic apparatus 100 may identify that integrated control is needed for the fourth space.

FIG. 15 is a diagram for illustrating an operation of identifying whether integrated control is needed based on power efficiency information.

Referring to FIG. 15, the home appliance may be an air conditioner. For example, the home appliance may be an apparatus related to air such as an air conditioner, an air purifier, a fan, and a circulator.

The electronic apparatus 100 may receive a user command in operation S1505. Here, the user command may be a command for controlling at least two home appliances. Then, the electronic apparatus 100 may obtain space information and home appliance information corresponding to the user command in operation S1510. Here, the space information corresponding to the user command may mean information related to the subject space to be controlled by the user. The information related to the subject space may include at least one of the structure of the subject space, the use of the subject space, or a target set value of the subject space. The home appliance information may include at least one of identification information of the home appliance, location information of the home appliance, or power efficiency information of the home appliance.

The electronic apparatus 100 may determine whether to use the auxiliary home appliance 401 based on power efficiency information in operation S1515. Specifically, if the power efficiency of a home appliance corresponding to a user command is lower than a threshold value, the electronic apparatus 100 may identify that the auxiliary home appliance 401 needs to be used. If the power efficiency is low, energy consumption may increase, and electricity may be consumed too much. Accordingly, the electronic apparatus 100 may perform control to help air circulation by using the auxiliary home appliance 401.

Specifically, the electronic apparatus 100 may identify a home appliance of which power efficiency is smaller than or equal to a threshold value, and identify the space in which the identified home appliance is located in operation S1520.

Then, the electronic apparatus 100 may identify an optimal location for circulating air from a space in which a home appliance having high power efficiency is located to a space in which a home appliance having low power efficiency is located in operation S1525. The optimal location may be a location wherein power consumption in a home is calculated to be the lowest when the auxiliary home appliance 401 performs an auxiliary operation of circulating air. An embodiment of moving to an optimal location will be described below in FIG. 19.

Then, the electronic apparatus 100 may identify blowing direction information of the auxiliary home appliance 401 for circulating air from the space in which the home appliance having high power efficiency is located to the space in which the home appliance having low power efficiency is located in operation S1530. For example, the blowing direction information may be information indicating by what angle among 360 degrees the air will be circulated. For example, in the embodiment of FIG. 19, the blowing direction information may be the direction of circulating air from the second space to the first space.

Then, the electronic apparatus 100 may identify blowing strength information of the auxiliary home appliance 401 based on the space information and the driving state information in operation S1535. Here, the driving state information may include at least one of the determined driving mode, target environment data (a target set value) corresponding to the driving mode, or current environment data (a sensed value) for performing a control operation corresponding to the user command. The electronic apparatus 100 may determine from which space to which space the air will be circulated based on the space information, and determine the blowing strength based on the target environment data and the current environment data included in the driving state information.

The blowing strength may be determined based on the space information. As the distance between the space in which the home appliance having high energy efficiency is located and the space in which the home appliance having low energy efficiency is located is farther, the blowing strength may become stronger.

The blowing strength may be determined based on the driving state information. As the difference between the target environment data (e.g., the target temperature) and the current environment data (e.g., the current temperature) is bigger, the blowing strength may become stronger.

Then, the electronic apparatus 100 may generate a control signal for controlling the auxiliary home appliance 401 based on the location information identified in the operation S1525, the blowing direction information identified in the operation S1530, and the blowing strength information identified in the operation S1535, and transmit the generated control signal to the auxiliary home appliance 401 in operation S1540.

FIG. 16 is a diagram for illustrating an operation of controlling an auxiliary home appliance in case target data is not reached within a threshold time.

Referring to FIG. 16, the electronic apparatus 100 may generate a control signal for controlling a plurality of home appliances based on a user command, and transmit the generated control signal to a subject home appliance in operation S1605. Then, the electronic apparatus 100 may identify whether a subject space (a space to be controlled) reached target environment data within a threshold time in operation S1610. For example, it is assumed that the electronic apparatus 100 received a user command for setting the target temperature of 24 degrees by using the first home appliance (an air conditioner) located in the first space. The electronic apparatus 100 may determine whether the first space reached 24 degrees which is the target temperature within the threshold time (e.g., 15 minutes).

In case the subject space reached the target environment data within the threshold time, the electronic apparatus 100 may identify whether the subject space is maintaining the target environment data per predetermined cycle in operation 1615. For example, even if the first space already reached the temperature of 24 degrees, the electronic apparatus 100 may identify whether the temperature of the first space maintains 24 degrees per predetermined cycle (e.g., 10 minutes).

In case the subject space did not reach the target environment data within the threshold time, the electronic apparatus 100 may identify the space that did not reach the target environment data in operation S1620. If the subject space is one space which is the first space in the operation S1605, the space identified in the operation S1620 may be the first space. However, if the subject spaces are at least two in the operation S1605, the electronic apparatus 100 may identify specific spaces that did not reach the target environment data among the plurality of spaces.

The reason that a space did not reach the target environment data may be because a problem occurred in the home appliance located in the space, or the performance of the home appliance is low. Accordingly, the electronic apparatus 100 may use the auxiliary home appliance 401 for performing a control operation for the identified space. For example, if the temperature of the first space does not reach the target, the electronic apparatus 100 may use the auxiliary home appliance 401 to circulate air in the first space.

Here, the electronic apparatus 100 may identify whether to move the auxiliary home appliance 401 to the identified space in operation S1625. If it is identified that the auxiliary home appliance 401 will be moved to the identified space, the electronic apparatus 100 may generate a control signal for moving the auxiliary home appliance 401 to the identified space, and transmit the generated control signal to the auxiliary home appliance 401 in operation S1630. Here, if it is identified that the auxiliary home appliance 401 will not be moved to the identified space, the electronic apparatus 100 may generate a control signal for performing an auxiliary operation in the current location without moving the auxiliary home appliance 401, and transmit the generated control signal to the auxiliary home appliance 401 in operation S1635.

FIG. 17 is a diagram for illustrating an operation of obtaining a photographed image through an auxiliary home appliance in case target data is not reached within a threshold time.

Referring to FIG. 17, the operations S1705, S1710, S1715, and S1720 may correspond to the operation S1605, S1610, S1615, and S1620 in FIG. 16, and thus overlapping explanation will be omitted.

After identifying a space that did not reach the target environment data, the electronic apparatus 100 may generate a control signal for moving the auxiliary home appliance 401 to the identified space, and transmit the generated control signal to the auxiliary home appliance 401 in operation S1725. Then, the electronic apparatus 100 may generate a control signal for photographing the identified space, and transmit the generated control signal to the auxiliary home appliance 401 in operation S1730. Here, the auxiliary home appliance 401 may photograph the identified space through the camera or the sensor included in the auxiliary home appliance 401 based on the control signal received from the electronic apparatus 100, and obtain a space image. Then, the auxiliary home appliance 401 may transmit the obtained space image to the electronic apparatus 100.

The electronic apparatus 100 may receive the space image from the auxiliary home appliance 401 in operation S1735. Then, the electronic apparatus 100 may analyze the reason that the identified space did not reach the target environment data based on the received space image. Specifically, the electronic apparatus 100 may analyze the space image, and identify the reason such as whether the window is opened, whether power of the home appliance is turned on, etc.

The electronic apparatus 100 may additionally provide the received space image to the user in operation S1740. Specifically, the electronic apparatus 100 may transmit the received space image to the user terminal 200, and the user terminal 200 may display the received space image on the display 240. The user may check the space image displayed on the user terminal 200 remotely, and resolve the problem. The operation S1740 may be automatically performed in the embodiment of FIG. 17, or may be performed only when the electronic apparatus 100 cannot identify the reason for the problem by itself.

FIG. 18 is a diagram for illustrating an operation of determining a blowing direction and blowing strength of an auxiliary home appliance.

Referring to FIG. 18, the electronic apparatus 100 may perform an operation for controlling the entire home appliances in the space 800. For example, the home appliances 601-1, 602-1, 603-1, 604-1, 605-1 related to air among the plurality of appliances included in the IoT network 400 may be integrally controlled. Here, environment data (e.g., the temperature) corresponding to each of the plurality of spaces (601 to 605 in FIG. 6) included in the space 800 may be different, and the electronic apparatus 100 may transmit a control signal to the plurality of home appliances 601-1, 602-1, 603-1, 604-1, 605-1 to reach the environment data that fits each space.

Here, the space 604 may be a kitchen. In a kitchen, there is a high possibility that cooking utensils, etc. may be included, and thus there is a high possibility that a lot of heat is generated or a lot of fine dust is generated. Accordingly, in the space 604, an air conditioner or an air purifier may not be installed. Accordingly, the electronic apparatus 100 may determine to circulate air from the third space 603 to the fourth space 604 based on the space information.

Here, the electronic apparatus 100 may use the auxiliary home appliance 401 to circulate air. Here, the auxiliary home appliance 401 may be an air blowing device (e.g., a fan or a circulator) for moving the air strongly.

The electronic apparatus 100 may identify the blowing direction such that the auxiliary home appliance 401 blows wind from the third space 603 to the fourth space 604. Also, the electronic apparatus 100 may determine the blowing strength based on the distance between the spaces and the driving state information.

In the embodiment of FIG. 18, the auxiliary home appliance 401 may perform an auxiliary operation (a blowing operation) as it is located in the third space 603 without moving.

FIG. 19 is a diagram for illustrating an operation that an auxiliary home appliance moves.

Referring to FIG. 19, the auxiliary home appliance 401 may perform an auxiliary operation after moving. Specifically, the electronic apparatus 100 may identify the optimal location of the auxiliary home appliance 401 for air circulation. The optimal location may be determined based on the structure information of the space 800. For example, it is assumed that air circulation is needed for the first space 601. The electronic apparatus 100 may identify the optimal location in the third space 603 which is the space in which the auxiliary home appliance 401 is currently located. Then, the electronic apparatus 100 may identify the blowing direction of the auxiliary home appliance 401 such that air is circulated from the second space 602 to the first space 601. Also, the electronic apparatus 100 may identify the blowing strength of the auxiliary home appliance 401 based on at least one of the space information or the driving state information.

The electronic apparatus 100 may transmit a control signal for controlling the auxiliary home appliance 401 based on the identified location, the identified blowing direction, and the identified blowing strength to the auxiliary home appliance 401.

FIG. 20 is a diagram for illustrating a photographed image photographed by an auxiliary home appliance.

Referring to FIG. 20, the electronic apparatus 100 may obtain a space image 2005 for a space in which a problem occurred. Specifically, a space in which a problem occurred may mean a space that did not reach target environment data within a threshold time. For example, in the case of the first space in which the window is opened, the target temperature cannot be reached even if the air conditioner is operated. Accordingly, even if the threshold time passes, the target temperature is not reached in the first space, and the first space may be identified as a space in which a problem occurred.

The electronic apparatus 100 may transmit a control signal for controlling the auxiliary home appliance 401 to directly move and photograph the image of the space in which a problem occurred to the auxiliary home appliance 401. Then, the auxiliary home appliance 401 may move to the space in which a problem occurred based on the received control signal, and then obtain the space image 2005 by photographing the image of the space through the camera or the sensor.

Here, the electronic apparatus 100 may inform the user of whether a problem occurred, and transmit the space image 2005. Specifically, the electronic apparatus 100 may transmit the space image 2005 to the user terminal 200, and the user terminal 200 may display the received space image 2005 on the display 240.

The user may directly check the space image 2005, and may intuitively determine what kind of problem occurred in the space.
