Referring to FIG. 1, the IoT device control system may include a control server 100, a user terminal 110, and a plurality of IoT devices 120. However, since the IoT device control system of FIG. 1 is only an embodiment of the present invention, the present invention is not limitedly interpreted through FIG. 1, and may be configured differently from FIG. 1 according to various embodiments of the present invention. .

Generally, each component of the IoT device control system of FIG. 1 is connected through a network (not shown). Network refers to a connection structure capable of exchanging information between nodes such as terminals and servers, and a local area network (LAN), a wide area network (WAN), and the Internet (WWW: World) Wide Web), wired and wireless data communication networks, telephone networks, and wired and wireless television communication networks. Examples of wireless data communication networks include 3G, 4G, 5G, 3rd Generation Partnership Project (3GPP), Long Term Evolution (LTE), World Interoperability for Microwave Access (WIMAX), Wi-Fi, Bluetooth communication, infrared communication, ultrasound Communication, Visible Light Communication (VLC), LiFi, and the like are included, but are not limited thereto.

The user terminal 110 may generate a text message including the IoT control command input from the user, and transmit the generated text message to the control server 100. Here, the text message may include a command for instructing the control of a plurality of IoT devices 120 installed in the user's premises. Here, the plurality of IoT devices 120 are various home devices installed in the home, for example, air conditioners, fans, dehumidifiers, TVs, washing machines, dryers, heating devices (boilers, heaters, etc.), air cleaners, lights, thermometers, etc. It can contain.

The control server 100 analyzes the IoT control command included in the text message received from the user terminal 110, and the IoT control command among the plurality of IoT devices 120 mapped with the identification information of the user terminal 110. At least one IoT device having an attribute corresponding to an analysis result may be grouped.

Hereinafter, the operation of each component of the IoT device control system of FIG. 1 will be described in more detail.

2 is a block diagram of the control server 100 shown in FIG. 1 according to an embodiment of the present invention.

Referring to FIG. 2, the control server 100 includes a table generation unit 200, a reception unit 210, a grouping unit 220, a collection unit 230, a control operation determination unit 240 and a control unit 250 can do. However, the control server 100 shown in FIG. 2 is only one example of implementation of the present invention, and various modifications are possible based on the components shown in FIG. 2.

Hereinafter, it will be described with reference to FIGS. 3 to 5B together with FIG. 2.

The table generator 200 may generate an IoT device attribute table for each of a plurality of user terminals. Specifically, the table generating unit 200 may generate an IoT device attribute table for a plurality of IoT devices mapped to each of identification information (eg, phone number, etc.) of the plurality of user terminals. For example, in each IoT device attribute table for each user terminal, as shown in FIG. 3, the operation reference attribute 303, the operation target attribute 305, the operation method attribute 307 according to the location of the user per IoT device 301, and Motion control state attribute 309. Referring to FIG. 3, the operation reference attribute 303 is an IN attribute operated when the user is indoors, an OUT attribute operated when the user is outdoors, and an operation when the user is located indoors or outdoors. IN / OUT attribute. For example, in the case of the 'boiler', the operation reference attribute of the 'boiler' has an 'IN attribute' because the user operates in a situation where the user is indoors. The operation target attribute 305 may mean an object controlled by each IoT device. For example, since each of the 'boiler' and the 'air conditioner' controls the indoor temperature, the operation target attribute of each of the 'boiler' and the 'air conditioner' has a 'temperature attribute'. The operation method attribute 307 means a control method for a control target of each IoT device, and the operation control state attribute 309 means a control setting state (or control operation category state) for a control target of each IoT device. You can. For example, in order for the 'alarm (indoor)' to operate in a situation where the user goes out, the operation method attribute of the 'alarm (indoor)' is set to 'ON attribute', and when an intruder enters the user's premises, the In order to output an alarm indicating whether or not intrusion, the operation control status attribute of 'alarm (indoor)' may be set as 'alarm attribute'.

The reception unit 210 may receive a text message including an IoT control command from the user terminal 110. For example, the receiver 210 may receive a text message 50 including 'one hour before work' from the user terminal 110, as shown in FIG. 5A.

The grouping unit 220 may analyze IoT control commands included in the text message. For example, the grouping unit 220 is based on a text message including 'one hour before work', and according to a user's work time, the 'action target attribute of an IoT device to be controlled among a plurality of IoT devices installed in the user's premises. 'Can be analyzed. As another example, when the user terminal 110 transmits a text message including 'sleep', the grouping unit 220 allows the user to sleep in a comfortable state based on the text message including 'sleep' It is possible to analyze the 'action target attribute' of the IoT device.

The grouping unit 220 uses the identification information (for example, a phone number) of the user terminal 110 that has sent a text message to IoT for a plurality of IoT devices mapped to the user terminal 110 among a plurality of IoT device attribute tables. Device attribute table can be extracted.

The grouping unit 220 may group at least one IoT device having an attribute corresponding to an analyzed result of a text message among a plurality of IoT devices 120 included in the extracted IoT device attribute table. Here, the plurality of IoT devices 120 may be managed by being mapped to identification information of the user terminal 110.

For example, referring to FIGS. 3 and 5A together, the IoT control command for 'one hour before work' included in the text message 50 is a command indicating a situation where a user enters a room indoors, so a grouping unit 220, the IoT device having the 'IN' attribute 'among the operation reference attributes 303 of the IoT device attribute table (FIG. 3) of the user terminal 110 is grouped into an operation ready state group, and having an' OUT attribute ' IoT devices can be grouped into a group of suspended (or idle state) states. At this time, the grouping unit 220 may manage the IoT devices grouped into the operation ready state group in an activated state, and periodically monitor them.

The collection unit 230 may collect indoor environment data from the grouped IoT devices. Specifically, the collection unit 230 may collect indoor environment data from IoT devices grouped into an operation ready state group. For example, the collection unit 230 may collect power on / off state information from each IoT device grouped into an operation ready state group. The collection unit 230 collects room temperature information (eg, room temperature 30 degrees) from the 'boiler and air conditioner' when the operation preparation group includes' boiler, air conditioner, dehumidifier, air purifier, and washing machine ', and' Dehumidifier 'collects indoor humidity information (e.g., 60% of indoor humidity), collects indoor air quality information (e.g., poor indoor fine dust concentration) from' air cleaner ', and collects information about the presence of laundry from' washer ' Can be collected.

In addition, the collection unit 230 may further collect outdoor temperature in order to control the indoor temperature of the user's home. For example, the collection unit 230 may collect outdoor temperature information from an externally installed IoT-type thermometer.

The control operation determination unit 240 may determine a control operation for the grouped IoT devices based on the collected indoor environment data. For example, the control operation determination unit 240 may determine the control operation for the grouped IoT device by comparing the collected indoor temperature information with the indoor temperature information preset by the user. At this time, when it is determined that the indoor temperature information is higher than the preset indoor temperature information, the control operation determination unit 240 may determine a control operation to lower the temperature through the grouped IoT devices.

For example, referring to FIGS. 3 and 4A together, when it is determined that the collected indoor temperature information is higher than the preset indoor temperature information and the indoor temperature needs to be lowered, the grouping unit 220 performs an operation target attribute in the IoT device attribute table. IoT devices having 305 having a 'temperature property' and an operating method property 307 having a 'DOWN property' may be grouped as shown in FIG. 4A. At this time, the grouped IoT device may include at least one air conditioner and a fan.

The control operation determining unit 240 collects the indoor temperature information preset by the user and collects the grouped IoT devices (IoT devices having 'temperature properties' and 'DOWN properties') in whole or selectively. Determine the temperature control action for the grouped IoT device based on the current temperature information included in the indoor environment data (e.g., the temperature range to lower the temperature, the operating time of the IoT device, and conditions for the operation priority of the IoT device) You can.

The control operation determination unit 240 determines the temperature control range of the indoor temperature and the operating time of the IoT device based on the indoor temperature information preset by the user and the current temperature information included in the collected indoor environment data, and grouped IoT Based on the determined result among the devices, at least one IoT device may be selected, and a temperature control operation for the selected IoT device may be determined. For example, if the collected indoor temperature is 31 degrees, the indoor temperature preset by the user is 25 degrees, and the temperature control time zone is before 10 pm, the control operation determination unit 240 may be used to select indoors among the grouped IoT devices. An air conditioner (for a living room or a living room) that can lower the temperature within a short period of time is selected, and a control operation to select and operate the air conditioner for the living room can be determined because the temperature control time zone corresponds to a time period for active activities in the living room. When the current time is not the bedtime period and the temperature difference between the collected indoor temperature and the preset indoor temperature is high, a control operation to simultaneously operate the fan together with the air conditioner for the living room may be determined. If the temperature difference between the collected indoor temperature and the preset indoor temperature is small, the control operation determination unit 240 may determine to control the indoor temperature to a comfortable state by operating only the electric fan.

As another example, the control operation determination unit 240 selects at least one IoT device among the grouped IoT devices based on the operation setting information of the IoT device according to the user's preference or the user's usage history of the IoT device, and the selected IoT device It can determine the temperature control operation for. For example, when a specific user sets the air conditioner for the bedroom to work after work or the air conditioner for the living room is set to operate on the weekend, a text message including 'one hour before work' is received from the user terminal of the specific user. In this case, the control operation determination unit 240 may determine a temperature control operation to operate the master air conditioner for temperature control based on the operation setting information of a specific user. The control operation determining unit 240 determines seasonal information based on current temperature information (outdoor temperature information) and date information included in the collected indoor environment data, and temperature for the IoT devices grouped based on the determined seasonal information Control action can be determined. For example, the control operation determiner 240 may determine a control operation to prevent the 'boiler' from being operated when the season is 'summer'.

The control operation determining unit 240 determines the driving priority between the grouped IoT devices based on the temperature difference between the indoor temperature information preset by the user and the current temperature information included in the collected indoor environment data, when the seasonal information is winter, , The temperature control operation for the grouped IoT devices may be determined based on the determined driving priority. For example, referring to FIGS. 3 and 4B together, when it is determined that the seasonal information is winter and the collected indoor temperature information is lower than the preset indoor temperature information, the indoor temperature needs to be increased, the grouping unit 220 is an IoT device In the attribute table, the IoT device having the 'UP attribute' may be grouped while the operation target attribute 305 has the 'temperature attribute' and the operation method attribute 307 may have the 'UP attribute'. At this time, the grouped IoT device may include a boiler and an indoor heater. If the temperature difference between the indoor temperature information (for example, 25 degrees) preset by the user and the collected indoor temperature information (for example, 15 degrees) is greater than a preset temperature difference, the control operation determination unit 240 may be the temperature among the grouped IoT devices It is possible to determine a control operation to operate a boiler having a long time required to raise the first time and to operate a room heater having a short time required to increase the temperature at a specific time (for example, 30 minutes before the user's work time).

On the other hand, when it is determined that the collected indoor air quality information is lower than the indoor air quality information preset by the user, the grouping unit 220 displays an IoT device in which the operation target attribute is 'air clean attribute' in the IoT device attribute table. You can group them together. At this time, the grouped IoT device may include at least one air purifier.

The control operation determination unit 240 may determine the air control operation for the grouped IoT devices based on the indoor air quality information preset by the user and the current indoor air quality information included in the collected indoor environment data. For example, when the difference between the indoor air quality information and the collected indoor air quality information is large (when the concentration of fine dust in the room is poor), the control operation determination unit 240 may determine to operate at least one air purifier. .

On the other hand, when it is determined that the collected indoor humidity information is higher than the indoor humidity information preset by the user, the grouping unit 220 may group IoT devices having an attribute of 'dehumidification' in the IoT device attribute table. . At this time, the grouped IoT device may include at least one dehumidifier.

The control operation determination unit 240 may determine the humidity control operation for the grouped IoT devices based on the indoor humidity information preset by the user and the current humidity information included in the collected indoor environment data. For example, when it is a rainy season and the indoor humidity is confirmed to be 60% or more, the control operation determination unit 240 may determine to operate at least one indoor dehumidifier.

On the other hand, if it is determined that the specific gravity of the laundry in the washing machine is higher than the specific gravity of the laundry set by the user, the grouping unit 220 groups the IoT device whose operation target attribute is 'laundry property' or 'dry property' in the IoT device property table. can do. In this case, a grouped washing machine and a dryer may be included.

The control operation determining unit 240 may determine the washing and drying control operation for the grouped IoT devices based on the collected current humidity information and the laundry specific gravity of the washing machine. For example, when the laundry is in the washing machine, the control operation determining unit 240 determines to operate the washing machine to complete the washing of the laundry within a specific time (after 1 hour of work), and the indoor humidity is high. You can even set the drying function to dry after washing.

The control unit 250 may transmit a control message including the determined control operation to the user terminal 110 and control the grouped IoT device based on whether the user terminal 110 approves the control message. For example, referring to FIGS. 5A and 5B, when the control unit 250 receives a text message 50 including an IoT control command (eg, 'one hour before work') from the user terminal 110, the controller A control message 52 including a control operation for at least one IoT device determined based on environmental data may be transmitted to the user terminal 110. At this time, the control message 52 is a response message to the text message 50 and may include control operation guide information for at least one IoT device to be controlled. For example, the control operation guide information included in the control message 52 is' the indoor temperature is 30 degrees, so the air conditioner will be operated after 40 minutes. We will operate the dehumidifier and air purifier right away because the indoor humidity is high and there is a lot of fine dust. Since there is a lot of laundry, it will start immediately and the indoor humidity will be high. In addition, when the approval message 54 for the control message 52 is received from the user terminal 110, the control unit 250 may operate at least one IoT device as the control message 52.

On the other hand, those skilled in the art, the table generating unit 200, the receiving unit 210, the grouping unit 220, the collection unit 230, the control operation determining unit 240 and the control unit 250, each of which is implemented separately, or of It will be fully understood that one or more can be implemented in an integrated manner.
