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 one embodiment of the present invention, the present invention is not limited to FIG. 1, and may be configured differently from FIG. 1 according to various embodiments of the present invention. .

In general, each component of the IoT device control system of FIG. 1 is connected through a network (not shown). Network refers to a connection structure that allows information exchange between nodes such as terminals and servers, including Local Area Network (LAN), Wide Area Network (WAN), and World Wide Area Network (WWW). Wide Web), wired and wireless data communication networks, telephone networks, wired and wireless television communication networks, etc. Examples of wireless data communication networks include 3G, 4G, 5G, 3GPP (3rd Generation Partnership Project), LTE (Long Term Evolution), WIMAX (World Interoperability for Microwave Access), Wi-Fi, Bluetooth communication, infrared communication, and ultrasound. This includes, but is not limited to, communication, Visible Light Communication (VLC), LiFi, etc.

The user terminal 110 may generate a text message containing an IoT control command input by the user and transmit the generated text message to the control server 100. Here, the text message may include commands that comprehensively instruct control of a plurality of IoT devices 120 installed in the user's home. Here, the plurality of IoT devices 120 are various home devices installed in the house, such as air conditioners, fans, dehumidifiers, TVs, washing machines, dryers, heating devices (boilers, heaters, etc.), air purifiers, lights, thermometers, etc. It can be included.

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

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

Figure 2 is a block diagram of the control server 100 shown in Figure 1, according to one embodiment of the present invention.

Referring to FIG. 2, the control server 100 includes a table creation 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 implementation example of the present invention, and various modifications are possible based on the components shown in FIG. 2.

Hereinafter, the description will be made with reference to FIGS. 3 to 5B along with FIG. 2.

The table generator 200 may generate an IoT device attribute table for each plurality of user terminals. Specifically, the table generator 200 may generate an IoT device attribute table for a plurality of IoT devices mapped to each identification information (eg, phone number, etc.) of a plurality of user terminals. For example, each IoT device attribute table for each user terminal includes an operation reference attribute 303, an operation target attribute 305, an operation method attribute 307 and the like according to the user's location for each IoT device 301, as shown in FIG. May include motion control state attributes 309. Referring to FIG. 3, the operation standard attribute 303 is an IN attribute that operates when the user is located indoors, an OUT attribute that operates when the user is outdoors, and an operation standard attribute that operates when the user is located indoors or outdoors. IN/OUT properties can be included. For example, in the case of 'boiler', since it operates when the user is indoors, the operation standard attribute of 'boiler' has 'IN attribute'. The operation target attribute 305 may refer to an object controlled by each IoT device. For example, since 'boiler' and 'air conditioner' each control the indoor temperature, the operation target property of 'boiler' and 'air conditioner' each has 'temperature property'. The operation method attribute 307 refers to the control method for the control object of each IoT device, and the operation control state attribute 309 refers to the control setting state (or control operation category state) for the control object of each IoT device. You can. For example, in order for the 'alarm (indoor)' to operate when the user is out, the operation method property of 'alarm (indoor)' is set to 'ON property', and when an intruder enters the user's home, the In order to output an alarm indicating whether there is an intrusion, the operation control state attribute of 'alarm (indoor)' can be set to 'alarm attribute'.

The receiving 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 '1 hour before leaving work' from the user terminal 110, as shown in FIG. 5A.

The grouping unit 220 can analyze the IoT control command included in the text message. For example, the grouping unit 220 selects the 'operation target attribute' of the IoT device to be controlled among the plurality of IoT devices installed in the user's home according to the user's work time based on the text message including '1 hour before leaving work'. ' can be analyzed. As another example, when the user terminal 110 transmits a text message containing the word 'sleep', the grouping unit 220 allows the user to sleep in a comfortable state based on the text message containing 'sleep'. The ‘operation target properties’ of IoT devices can be analyzed.

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

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

For example, referring to FIGS. 3 and 5A together, the IoT control command for '1 hour before leaving work' included in the text message 50 is a command indicating a situation in which the user enters the home, so the grouping unit (220) groups IoT devices with 'IN' attribute' among the operation standard attributes (303) of the IoT device attribute table (FIG. 3) of the user terminal 110 into an operation ready state group, and groups IoT devices with 'OUT attribute' IoT devices can be grouped into no-operation (or standby state transition) state groups. 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 grouped IoT devices. Specifically, the collection unit 230 may collect indoor environment data from IoT devices grouped into operation readiness groups. For example, the collection unit 230 may collect power on/off state information from each IoT device grouped into an operation readiness state group. When the operation readiness group includes 'boiler, air conditioner, dehumidifier, air purifier, washing machine', the collection unit 230 collects indoor temperature information (e.g., indoor temperature 30 degrees) from 'boiler and air conditioner', and ' Indoor humidity information (e.g., indoor humidity 60%) is collected from the 'dehumidifier', indoor air quality information (e.g., poor indoor fine dust concentration) is collected from the 'air purifier', and information about the presence of laundry is collected from the 'washing machine'. It can be collected.

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

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 a control operation for the grouped IoT devices by comparing the collected indoor temperature information with the indoor temperature information preset by the user. At this time, if 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 device.

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

The control operation decision unit 240 uses the indoor temperature information preset by the user and the collected data to determine whether to operate all or selectively the grouped IoT devices (IoT devices with 'temperature properties' and 'DOWN properties') Based on the current temperature information contained in the indoor environment data, determine temperature control actions for grouped IoT devices (e.g., temperature range to cool down, operating time of IoT devices, and conditions for operating priority of IoT devices). You can.

The control operation decision 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 determines the temperature control range of the indoor temperature and the operating time of the IoT device. At least one IoT device may be selected based on the determined result among the devices, 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 is before 10 p.m., the control operation decision unit 240 determines the indoor temperature among the grouped IoT devices. You can select an air conditioner (for the living room or master bedroom) that can lower the temperature quickly, and since the temperature control time period corresponds to the time when you will be active in the living room, you can select the air conditioner for the living room and determine the control operation to operate it. If the current time is not the bedtime zone and the temperature difference between the collected indoor temperature and the preset indoor temperature is high, a control operation to simultaneously operate the electric fan along with the living room air conditioner may be determined. If the temperature difference between the collected indoor temperature and the preset indoor temperature is small, the control operation decision unit 240 may determine to control the indoor temperature to a comfortable state by operating only the fan.

As another example, the control operation determination unit 240 selects at least one IoT device from grouped IoT devices based on operation setting information of the IoT device according to the user's preference or the user's usage history of the IoT device, and selects the selected IoT device. The temperature control operation can be determined. For example, when a specific user sets the air conditioner in the master bedroom to operate after work or the air conditioner in the living room to operate on the weekend, a text message containing '1 hour before leaving work' is received from the specific user's user terminal. In this case, the control operation determination unit 240 may determine a temperature control operation to operate the home air conditioner for temperature control based on operation setting information of a specific user. The control operation determination unit 240 determines seasonal information based on the current temperature information (outdoor temperature information) and date information included in the collected indoor environment data, and determines the temperature for the grouped IoT devices based on the determined seasonal information. Control actions can be determined. For example, the control operation determination unit 240 may determine a control operation to prevent the 'boiler' from operating when the season is 'summer'.

The control operation decision unit 240 determines the driving priority among the grouped IoT devices based on the season information being winter and the temperature difference between the indoor temperature information preset by the user and the current temperature information included in the collected indoor environment data. , Temperature control operations for grouped IoT devices can be determined based on the determined driving priority. For example, referring to FIGS. 3 and 4B together, when the season information is winter and it is determined that the indoor temperature needs to be increased because the collected indoor temperature information is lower than the preset indoor temperature information, the grouping unit 220 is an IoT device. In the attribute table, IoT devices whose operation target attribute 305 has 'temperature attribute' and whose operation method attribute 307 has 'UP attribute' can be grouped. At this time, grouped IoT devices may include boilers and indoor heaters. If the temperature difference between the indoor temperature information (e.g., 25 degrees) preset by the user and the collected indoor temperature information (e.g., 15 degrees) is greater than the preset temperature difference, the control operation determination unit 240 determines the temperature among the grouped IoT devices. A control operation may be determined to operate the boiler, which takes a long time to raise the temperature, first, and to operate the indoor heater, which takes a short time to raise the temperature, at a specific time (for example, 30 minutes before the user leaves work).

Meanwhile, if 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 selects the IoT device whose operation target attribute is 'air cleanliness attribute' in the IoT device attribute table as shown in Figure 4b and They can be grouped together. At this time, the grouped IoT device may include at least one air purifier.

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

Meanwhile, if 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 whose operation target attribute is 'dehumidifying attribute' 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 a humidity control operation for the grouped IoT devices based on indoor humidity information preset by the user and current humidity information included in the collected indoor environment data. For example, if it is the 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.

Meanwhile, when it is determined that the proportion of laundry in the washing machine is higher than the proportion of laundry set by the user, the grouping unit 220 groups IoT devices whose operation target properties are 'washing properties' or 'drying properties' in the IoT device property table. can do. At this time, grouped washing machines and dryers may be included.

The control operation determination unit 240 may determine washing and drying control operations for the grouped IoT devices based on the collected current humidity information and the specific gravity of laundry in the washing machine. For example, when laundry is in the washing machine, the control operation decision unit 240 determines to operate the washing machine to complete washing of the laundry within a specific time (one hour after the user leaves work), and the current 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 devices based on whether the user terminal 110 approves the control message. For example, referring to FIGS. 5A and 5B, when a text message 50 containing an IoT control command (e.g., ‘1 hour before work’) is received from the user terminal 110, the control unit 250 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 guidance information for at least one IoT device to be controlled. For example, the control operation guidance information included in the control message 52 is 'The indoor temperature is 30 degrees, so the air conditioner will start in 40 minutes. The indoor humidity is high and there is a lot of fine dust, so we will immediately turn on the dehumidifier and air purifier. It can be written as 'I will start the laundry immediately because there is a lot of laundry, and the dryer will also be turned on because the indoor humidity is high.' Additionally, when the control unit 250 receives the approval message 54 for the control message 52 from the user terminal 110, the control unit 250 may operate at least one IoT device according to the control message 52.

Meanwhile, those skilled in the art will know that the table creation unit 200, the receiving unit 210, the grouping unit 220, the collection unit 230, the control operation determination unit 240, and the control unit 250 are each implemented separately, or one of them is implemented separately. It will be fully understood that more than one may be integrated and implemented.
