Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface, or the presence of an object in the vicinity of the detection surface, without mechanical contact by using electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by the touch screen.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have. Meanwhile, the control unit 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141 as described above, and further provides visual information corresponding to the processed data It can be output on the touch screen. Furthermore, the control unit 180 can control the mobile terminal 100 such that different operations or data (or information) are processed according to whether the touch to the same point on the touch screen is a proximity touch or a touch touch .

The touch sensor uses a touch (or touch input) applied to the touch screen (or the display unit 151) by using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, Detection.

For example, the touch sensor may be configured to convert a change in a pressure applied to a specific portion of the touch screen or a capacitance generated in a specific portion to an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, a capacitance at the time of touch, and the like where a touch object touching the touch screen is touched on the touch sensor. Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

Thus, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object touching the touch screen (or a touch key provided on the touch screen). Whether to perform different controls or to perform the same control according to the type of the touch object may be determined according to the current state of the mobile terminal 100 or an application program being executed.

Touch can be sensed.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera 121 includes at least one of a camera sensor (for example, a CCD, a CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.

The memory 170 may store a program for the operation of the controller 180 and temporarily store input / output data (e.g., a phone book, a message, a still image, a moving picture, etc.). The memory 170 may store data on vibration and sound of various patterns outputted when a touch is input on the touch screen.

The memory 170 may be a flash memory type, a hard disk type, a solid state disk type, an SDD type (Silicon Disk Drive type), a multimedia card micro type ), Card type memory (e.g., SD or XD memory), random access memory (RAM), static random access memory (SRAM), read-only memory (ROM), electrically erasable programmable read memory, a programmable read-only memory (PROM), a magnetic memory, a magnetic disk, and / or an optical disk. The mobile terminal 100 may operate in association with a web storage that performs the storage function of the memory 170 on the Internet.

Meanwhile, as described above, the control unit 180 controls the operations related to the application program and the general operation of the mobile terminal 100. [ For example, when the state of the mobile terminal meets a set condition, the control unit 180 can execute or release a lock state for restricting input of a user's control command to applications.

In addition, the control unit 180 performs control and processing related to voice communication, data communication, video call, or the like, or performs pattern recognition processing to recognize handwriting input or drawing input performed on the touch screen as characters and images, respectively . Further, the controller 180 may control any one or a plurality of the above-described components in order to implement various embodiments described below on the mobile terminal 100 according to the present invention.

In the following, various embodiments may be embodied in a recording medium readable by a computer or similar device using, for example, software, hardware, or a combination thereof.

The smart fan 160 and the mobile terminal 100 may be confused by a common designation, but they will be distinguished using their identification codes. For example, the control unit 242 is a control unit of the smart fan 160, and the control unit 180 is a control unit of the mobile terminal 100.

Hereinafter, a method of driving the smart fan 260 in conjunction with the mobile terminal 100 according to an embodiment of the present invention will be described in detail.

In the present invention, a smart fan 160 that can be controlled using the mobile terminal 100 is provided in order to utilize a CPU having high processing capability and the like provided in a smart phone or the like. Especially, when the user is sleeping, the use of a fan is not effective. Accordingly, it is desirable to control the smart fan 160 so as to operate in a predetermined operation pattern through the mobile terminal 100.

4 is a flowchart illustrating a control procedure of the mobile terminal 100 for controlling the smart fan 160 according to an embodiment of the present invention.

In step S401, the controller 180 determines whether the user enters the sleep mode. If the user does not enter the sleep mode, the process proceeds to step S402.

In step S402, the control unit 180 may receive an input on the wind direction and / or the wind speed from the user through the user input unit 123. [ For example, a button corresponding to 'strong wind', 'paralysis' or 'gentle wind' may be output through the touch screen 151 provided in the mobile terminal 100, and an input for touching the corresponding button may be received .

In response to the user input received in step S402, the fan control signal may be transmitted to the smart fan 160 in step S403. The control unit 242 of the smart fan 160 receiving the control signal may control the wind direction and / or the wind speed by controlling the driving unit 202 according to the control signal.

On the other hand, if the user enters the sleep mode, the process can proceed to step S404.

In step S404, the control unit 180 may invoke the wind direction and wind speed pattern for operating in the sleep mode. At this time, it may mean to search for a pre-stored wind direction or wind speed pattern in the memory 170. In step S405, the smart fan 160 can be controlled according to the fetched wind direction and wind speed pattern.

Not only is the temperature dropping after the sun goes down, but the body temperature is getting lower when it is asleep. Therefore, it may be better for the wind speed to gradually decrease after sleeping.

In one embodiment of the present invention, it may be possible to control the wind speed (in a weak wind) to be lowered in a certain time period (3 to 6 am). Since the temperature can rise again after the sunrise, after that time, you will be able to switch back to the original wind speed or the appropriate wind speed in that time zone.

Furthermore, in the present invention, the power of the smart fan 160 can be automatically turned off when a predetermined time elapses as in step S406.

Meanwhile, in the present invention, a system capable of controlling the indoor temperature using the smart fan 160 and the mobile terminal 100 is proposed.

The room temperature is generally caused by the convection phenomenon. The radiation or conduction method has little effect on the room temperature. Accordingly, even if the indoor air is properly circulated, the overall indoor temperature can be effectively controlled. In particular, even if the cold air of the air conditioner is properly circulated, a high temperature lowering effect can be obtained by using less power.

Therefore, the present invention proposes a control system that receives various information through the mobile terminal 100, and synthesizes the information to obtain the most optimal effect.

The various information includes information on the indoor structure, information on the relative position of the smart fan 160, temperature information at each point, and information on where the user is located.

The relative position may refer to a position between the plurality of smart electric fans 160, but may indicate a position on the indoor structure.

In addition, in the embodiment for explaining the present invention, only the case of a fan is taken as an example, but any device capable of controlling the temperature by generating wind such as a blower or an air conditioner can be included in the embodiment of the present invention.

Hereinafter, a method of receiving information in detail will be described.

5 to 8 illustrate a method for receiving information and a specific method for controlling the room temperature using the method according to an embodiment of the present invention.

5, the mobile terminal 100 outputs an indoor structure 501 (a floor plan for an indoor structure) through a display 151 (in this example, a touch screen). The output of the indoor structure may be determined by the user selecting from a list of various room structures, downloaded information on the house structure in which the user lives, or may be outputted in a manner that the actual user directly draws the structure of the house will be. The embodiment of the present invention is not limited to the method of inputting the indoor structure.

In an embodiment of the present invention, location information indicating where the smart fan 160 is located may be further input on the indoor structure. The location information may be received by the touch input 10a on the outputting room structure 501. [ That is, it is possible to designate the position of the smart fan 160 by touching the corresponding position on the output structure.

Each of the smart electric fans 160-1 to 160-4 can measure the temperature at the corresponding position and transmit the measured temperature to the mobile terminal 100. [

The mobile terminal 100 can determine the wind direction and the wind speed by taking into account the received measurement temperatures, the indoor structure, and the position information of the smart electric fans 160-1 to 160-4. In consideration of the indoor structure, it is possible to consider not only the position and size of each room, but also the position and length of the wall in the presence of the wall.

For example, when the temperature difference measured in each of the smart electric fans 160-1 to 160-4 is relatively large, the temperature can be changed to strong wind to keep the room temperature uniform. On the contrary, when the difference in temperature measured in each of the smart electric fans 160-1 to 160-4 is relatively small or constant, the wind speed can be changed to a weak wind to induce proper air circulation.

On the other hand, in the present invention, it is proposed not only to change the wind speed but also to control the wind direction.

5, the fourth smart fan 160-4 blows air in a first air blowing direction 510-1 toward the living room 505. [ However, when the living room 505 has an air conditioner, it is assumed that the living room 505 in which the fourth smart electric fan 160-4 is located can maintain a low temperature, but the temperature of the other bedroom or kitchen is high.

In this case, for effective circulation of air, the airflow direction of the fourth smart fan 160-4 should be changed from the living room 505 toward the other second air blowing direction 510-2.

That is, the mobile terminal 100 may be configured such that a smart fan 160 (160-4) having a high temperature is used in a smart fan (160-4 in FIG. 5) having a low temperature based on a temperature value measured from the plurality of smart fans 160-1 to 160-4 -1 to 160-4) direction 510-2. At this time, it is obvious that the greater the temperature difference, the stronger the wind speed can be.

It is necessary to switch the flow of the air to the bedroom 2 503 because the measurement temperature of the third smart fan 160-3 is 22 degrees and the temperature of the second smart fan 160-2 is 25 degrees have. Accordingly, the mobile terminal 100 can control the wind direction of the third smart fan 160-3 in the third wind direction 510-3. When controlling the air blowing direction, the air blowing direction can be controlled to a range that does not face the wall according to the indoor structure information.

Referring to FIG. 7, both the kitchen 504 and the bedroom 2 503 are maintained at a proper temperature, but the bedroom 1 502 is still maintained at a high temperature.

Accordingly, the mobile terminal 100 may control air flow direction of the smart electric fans 160-1 to 160-4 to circulate air to the bedroom 1 (502).

To do so, it may be effective to control the blowing direction of the second smart fan 160-2 rather than to control the blowing direction of the first smart fan 160-1. This is because, when the position of the first smart electric fan 160-1 is seen, even if wind is directed toward the bedroom 1 502, it is blocked by the wall.

Accordingly, the mobile terminal 100 may adjust the airflow direction of the second smart fan 160-2 to 510-4 and circulate the air to the bedroom 1.

That is, when controlling the air blowing direction, the mobile terminal 100 can limit the air blowing direction only in the direction in which the obstacle is not present, if there is an obstacle (wall, etc.) according to the indoor structure. That is, it is possible to control only the blowing direction in the case where there is no obstacle.

On the other hand, in the present invention, there is no need to circulate air in a room without a person on the inside of the room structure, so it is suggested not to blow air to the corresponding position.

Referring to FIG. 8, when the input (10b), which does not blow air to the bedroom 1 (502), is received, the control for air flow to the room is not performed. For example, in FIG. 7, the blowing direction 510-4 toward the bedroom 1 502 can be switched 510-3 toward the bedroom 2 503 direction.

That is, when the user selects one of the plurality of rooms or the living room, the mobile terminal 100 can stop the blowing of the smart fan 160 blowing in the corresponding direction or switch to another direction.

Furthermore, when there is a smart fan 160 located in the selected room, the power of the smart fan 160 itself can be controlled to be turned off.

On the other hand, in the present invention, since it is characteristic to control the blowing direction of the fan, it is proposed to designate the reference direction when installing the fan.

9 is a view showing an example of a method of designating a blowing reference direction of a fan according to an embodiment of the present invention.

The reference direction may mean a specific direction of the fan, for example, a direction in which the direction indicator 241 of the fan shown in FIG. 1 is directed.

As shown in FIG. 5, after the input 10a designating the position of the specific smart fan 160-3 is received, when the input 10c designating the direction is received from the corresponding position, the reference direction of the fan Can be designated as the heading. At this time, the input 10c for designating the direction may be a drag drop (drag-out after touching) input in a corresponding direction after the touch screen 151 is touched for the input 10a for specifying the position .

As described above, if the position where the smart fan 160 is installed and the direction in which the smart fan 160 is installed can be clearly specified, the mobile terminal 100 can accurately control the blowing direction of the fan.

Lastly, in the case of the smart fan according to the present invention, it is possible to remotely control the smart fan through the mobile terminal and to control a plurality of smart fans, thereby maximizing convenience for the user.

Although the embodiments of the mobile terminal, the fan, and the temperature control system using the same according to the present invention have been described above, the present invention is not limited to the technical idea, structure and operation of the present invention. And the scope of the technical idea of the present invention is not limited by the description with reference to the drawings or the drawings.
