The present invention relates to a user terminal and a method of controlling an IoT device using the same, and is capable of remotely controlling an electric appliance or a lighting device connected to the IoT device by sending a signal to the IoT device wirelessly connected to a user terminal such as a smart phone We propose a method.

FIG. 1 is a diagram illustrating an IoT device control system according to an embodiment of the present invention, and FIG. 2 is a diagram illustrating an example of the system of FIG.

1 and 2, an IoT device control system according to an embodiment of the present invention includes a user terminal 100, a plurality of IoT devices 200, 300, and 400, and control target devices 10 , 20).

The user terminal 100 corresponds to a smart phone, a smart pad, a tablet PC, a notebook computer, etc., and is wirelessly connected to the IoT devices 200, 300, and 400 through Wi-Fi communication. The user terminal 100 can control the IoT devices 200, 300, and 400 while the application program (ex, application) is executed.

The application program can provide a list of IoT devices that are pre-registered or within communication range, can transmit control commands to the IoT device, and can receive various data from the IoT device. The application can also manage and provide control history for individual IoT devices. As described above, the embodiment of the present invention can provide an application such as a mobile app (App) capable of controlling various IoT devices to a user terminal.

The IoT devices 200, 300, and 400 directly control driving or power supply of the corresponding electric device 10 or the lighting device 20 connected to the IoT devices 200, 300, and 400 based on the control command received from the user terminal 100.

The remote control device 200 is provided with a normal remote control function for remotely controlling the electric device 10 through infrared communication or the like and a communication function ex- Fi module). The remote control device 200 corresponds to a device connected to the electric device 10 through infrared communication.

The receptacle device 300 has a receptacle to which the plug of the electric device 10 can be connected and has a function of supplying or cutting off electric power supplied from the outside to the electric device 10, Communication function (ex, Wi-Fi module). The receptacle device 300 corresponds to a device electrically connected to the electric device 10. [

The electric device 10 such as the TV shown in FIG. 2 is a device that can use both the remote control device 200 and the outlet device 300 and can be remotely controlled through the remote control device 200 and can be controlled through the outlet device 300 External power can be supplied. The electric devices 10 having similar properties include a cooling and heating device, an air conditioner, an electric heater, an electric fan, a monitor, and the like.

The lighting control device 400 is installed on a wall surface to control the operation of the lighting device 20 and has functions of a normal lighting and a light switch and a communication function ex- Fi module). Such a lighting control device 400 corresponds to a device connected to the lighting device 20 in a wired manner and can directly control the power supply of the lighting device 20. [

Although the IoT devices 200, 300, and 400 as described above have a function of manually controlling an apparatus by receiving an operation signal of a user through a switch or a button provided outside the apparatus, And the like.

In the embodiment of the present invention, on the basis of the control signal received from the user terminal 100 by the IoT devices 200, 300 and 400, control of the end electrical device 10 and the lighting device 20 (turn on / Supply / shutdown, etc.).

That is, the ultimate control target in the embodiment of the present invention corresponds not to the IoT devices 200, 300, and 400 but to various electric devices 10 and lighting devices 20 existing in a home, an office, a business place, or the like. When the control command is received from the user terminal 100, the IoT devices 200, 300, and 400 control operations of the devices 10 and 20 according to the received command.

In the present embodiment, the IoT devices 200, 300, and 400 exemplify a Wi-Fi module as a module for communication with the user terminal 100 and may be replaced or mixed with various well-known modules (ex, RF, Bluetooth). Also, the IoT devices 200, 300, and 400 may be directly connected to the user terminal 100 as shown in FIG. 1, or may be connected through additional devices (ex. Access points) as shown in FIG.

1 illustrates a method in which the user terminal 100 is directly connected to the IoT devices 200, 300, and 400 through Wi-Fi communication, and is directly connected to the IoT device through an app of a smart phone .

FIG. 3 is a diagram illustrating a case where additional communication equipment is utilized in the system of FIG. 1; 3 shows IoT devices as one block for convenience of explanation. In the case of FIG. 3, the user terminal 100 can access the wireless Internet (ex, home AP) and control the location without restriction, and has two communication methods.

One of them is a method in which the user terminal 100 communicates with the IoT devices 200, 300 and 400 via an access point (AP) 500. In this case, when the user terminal 1000 accesses the Wi- Fi connection, the IoT devices 200, 300, and 400 are controlled. The IoT devices 200, 300, and 400 are wirelessly connected to the access point 500 using the built-in Wi-Fi module.

The other is that the user terminal 100 communicates with the IoT devices 200, 300, and 400 via the access point 500 and the Hub Coordinator 600 while the hub coordinator 600 Controls the IoT devices 200, 300, and 400 through RF communication. The hub coordinator 600 is Wi-Fi connected to the access point 500 and communicates with the IoT devices 200, 300, and 400 in an RF manner. Therefore, in this case, the IoT devices 200, 300, and 400 use RF modules, not Wi-Fi modules.

The embodiments of the present invention can be selectively used among the communication methods described above. Further, the communication method may be varied depending on the surrounding environment or the current situation.

Hereinafter, a configuration of a user terminal according to an embodiment of the present invention will be described. The user terminal can provide related services while the app (App) is running.

4 is a diagram illustrating the configuration of the user terminal shown in FIG. Referring to FIG. 4, the user terminal 100 includes a device list providing unit 110, a control command transmitting unit 120, a data receiving unit 130, and a control status determining unit 140.

The device list providing unit 110 provides a list of at least one device registered as a control target and an instruction menu that can be transferred on a device-by-device basis to the application-driven image. For example, when the user terminal 100 executes an application, a list of controllable IoT devices is provided, and a menu related to a command that can be sent to the device when a predetermined device is selected is displayed in the form of text, .

The control command transmission unit 120 transmits the control command to the remote controller device 100 when the remote controller device 100 is selected from the list of the devices by the user and the remote controller device 100 receives a turn- And transmits a turn-off command. The remote control device 100 controls the electric device 10 through infrared communication and turns off the electric device 10 upon receiving the turn-off command.

The data receiving unit 130 receives the power measurement data of the electric device 10 from the receptacle device 200 that controls power supply to the electric device 10. [ Here, the reason why the electric quantity measurement data is additionally received from the outlet device 200 is to confirm whether the electric device 10 is turned off properly.

The control state determiner 140 determines whether the electric device 10 is turned off based on the electric power amount measurement data received from the outlet device 300 and determines whether the electric device 10 is turned off .

If the power amount of the electric device 10 does not fall below the threshold value after the turn-off command transmission, the control state determiner 140 may determine that the electric device 10 is not turned off. Here, the amount of power below the threshold value may correspond to an amount of standby power consumed when the electric device 10 is turned off.

The control command transmission unit 120 retransmits the turn-off command to the remote controller device 100 and retries the turn-off command, or if the electric device 10 is not turned off, 10 to the outlet device 300 to cut off the power supply.

As described above, according to the embodiment of the present invention, when the power consumption of the electric device 10 after the turn-off of the electric device 10 in the user terminal 100 does not fall below the reference value, the electric device 10 is not turned off properly The power supply to the electric device 10 is cut off. The specific method will be described in more detail with reference to the following drawings.

5 is a diagram illustrating a method of controlling an IoT device using a user terminal according to a first embodiment of the present invention. The following control method assumes that an application program (application) installed in the user terminal 100 is executed.

First, when the user terminal 100 selects a turn-off menu in a state in which the remote control device 200 is selected from the list of devices displayed on the application driving screen (S510), the remote control device 200 transmits the turn- 10 (S520).

Then, the remote control device 200 transmits a turn-off signal to the corresponding electric device 10 using the infrared communication (S530). If the electric device 10 is a TV, if the device is normally turned off, the screen is turned off and only standby power is generated. In addition, after transmitting the turn-off signal, the remote control device 200 can feed back the fact to the user terminal 100.

Then, the user terminal 100 receives power measurement data of the electric device 10 from the outlet device 300 (S540). In operation S540, the user terminal 100 may request feedback to the outlet device 300 that receives power from the corresponding electric device 10, and may request feedback when the information is not received. In addition, the outlet device 300 may periodically provide the power measurement data to the user terminal 100 to which the outlet device 300 is connected.

Next, the user terminal 100 analyzes the received power amount measurement data (S550), and determines whether the electric device 10 is turned off based on the received power amount measurement data (S560).

The user terminal 100 may determine that the electric device 10 maintains the existing turn-on state if the amount of electric power of the electric device 10 does not fall below the threshold value even after the turn-off command. If the electric device 10 is normally turned off, the electric device 10 will only consume about the standby power below the threshold value, but will continue to consume more power if the turn-on state is maintained.

If it is determined in step S560 that the electric device 10 is turned off, the user terminal 100 notifies the electric device 10 that the electric device 10 is turned off as requested (S570).

On the contrary, if it is determined that the electric device 10 is not turned off, the user terminal 100 may retry the turn-off command to the remote control device 200 to retry the above process (S580) 300 to shut off the power supply to the electric device 10 (S585). That is, in the case where it is not turned off, one of the two processes described above can be selectively used.

When the outlet device 300 receives the power supply cutoff command from the user terminal 100, the outlet device 300 cuts off the power supply to the connection part of the corresponding electric device 10 (S590). In this case, since the power supply voltage is not supplied to the electric device 10 at all, the power consumption will be zero.

In the embodiment of the present invention, when the electric device 10 is an air conditioner or an electric heater, the user terminal 100 can additionally receive temperature measurement data from a temperature sensor (not shown) around the electric device 10 have. That is, in addition to the power measurement data, the temperature measurement data is additionally used to determine whether to retransmit the turn-off command or transmit the power-off command.

In the case of air conditioners or electric heaters, unwanted operation or excessive operation may cause a cold, air-condition, burn or fire. The temperature sensor used in the embodiment of the present invention may be implemented as an IoT sensor having a communication module incorporated therein. Of course, the temperature sensor can be implemented in the form of being embedded in other IoT sensors or devices.

6 is a view showing a control method in the case where the electric device is an air conditioner or an electric heater in the first embodiment of the present invention. 6, the description of the steps overlapping with the case of FIG. 5 is omitted,

The user terminal 100 receives and analyzes the power measurement data from the outlet device 300 in order to check whether the turn off of the electric device 10 is normal after transmitting the turn off command of the electric device 10 to the remote control device 200 ), The temperature measurement data is received from the temperature sensor and analyzed (S620). Both processes can be done simultaneously or step by step.

The data analysis is intended to know whether the power amount of the electric device 10 is below a preset threshold value or whether the temperature measurement data has deviated from the reference temperature range. The reference temperature range may correspond to a temperature range that can be obtained after the turn-off command, and may correspond to any set temperature range that does not cause a cold, an air conditioner, burn, or the like.

The comparison of the temperature data may be made immediately after the transmission of the turn-off command of the user terminal 100 or may be performed with a time difference after the set time. If there is a time difference, it is first determined whether the amount of power after the turn-off command has fallen below a predetermined threshold value, and then it is judged whether or not the temperature at the elapse of the set time falls within the set temperature range.

Thereafter, the user terminal 100 determines whether the power amount of the electric device 10 is less than a threshold value as a result of data analysis (S630). If the power amount is less than the threshold value, it is determined whether the temperature is within the reference temperature range again (S640). If the electric energy is less than the threshold value and the temperature is within the reference temperature range, the electric appliance 10 is regarded as safely turned off and the normal turn-off of the electric appliance 10 is notified (S650). However, if the power amount is less than the threshold value but the temperature deviates from the reference temperature range, the remote control device 200 retransmits the turn-off command of the electric device 10 to retry the turn-off operation (S670).

If it is determined in step S630 that the power amount is not less than the threshold value, it is determined whether the temperature is within the reference temperature range (S660). If the temperature is within the reference temperature range, the remote control device 200 retransmits the turn-off command of the electric device 10 and retries the turn-off operation (S670). However, if the amount of electric power is equal to or higher than the threshold value and the temperature also deviates from the reference temperature range, the outlet device 300 is instructed to interrupt the power supply of the electric device 10 (S680).

The user terminal 100 may notify the user of the electric device 10 that the amount of electric power of the electric device 10 has not dropped below the threshold value and the temperature measurement data has deviated from the reference temperature range. And transmits a power supply cutoff command. In the case where either one of the above two is applicable, the remote control device 200 retransmits the turn-off command. If both of them are satisfied, it is recognized that the situation is more dangerous than when only one is satisfied and the power of the electric device 10 is immediately shut off.

Meanwhile, the embodiment of the present invention is also capable of controlling the operation of the lighting apparatus 20 through the control of the lighting control device 400. [ Hereinafter, this will be described in detail with reference to FIG. 2 and FIG.

7 is a diagram illustrating a method of controlling an IoT device using a user terminal according to a second embodiment of the present invention. First, the user terminal 100 selects the light-off menu from the list of devices from the user and selects the light-off menu in step S710. Then, the user control unit 400 controls the light- (S720). Then, the illumination control device 400 turns off the illumination device 20 (S730).

Thereafter, the user terminal 100 receives illumination sensing data from the illumination control device 400 (S740). The illumination control device 400 incorporates an illuminance sensor and transmits the sensed illumination data to the user terminal 100 through its own communication module. In addition, the illumination control device 400 may transmit the illumination data together with the response to the user control terminal 100 as a light control result.

Thereafter, the user terminal 100 determines whether the illumination device 20 is turned off based on illumination sensing data (S750). If the illuminance is less than the threshold value, the user terminal 100 determines that the illumination device 20 is turned off and informs the user of the normal operation of turning off the app display screen (S760).

However, if the illuminance is equal to or greater than the threshold value, it is determined that the illumination device 20 is not turned off, and the illumination control device 400 retransmits the turn-off command to retry the turn-off operation (S770).

According to the embodiment of the present invention, it is possible to remotely control an electric or lighting device which is not directly controllable by the user terminal 100 via the IoT devices, and to use various IoT devices associated with the device Dual control is also possible, which can increase control accuracy and prevent safety accidents.

According to the user terminal and the device control method using the same according to the present invention, it is possible to more effectively control the IoT devices configured to control the electric device or the lighting device in a predetermined space, thereby minimizing the control error and improving the accuracy .
