Here, the reference blood pressure, the reference heart rate, or the reference pulse rate may be a set value determined by an experiment, or may be an average value of blood pressure, heart rate, and pulse rate value hit by the memory 240, which will be described later.

For example, the user state determination unit 281 determines that the user's body temperature abnormality is detected when the degree of the user's sensed temperature or the temperature of the user, which is calculated through the information input from the plurality of sensors, deviates from the reference temperature or the reference temperature range can do.

Specifically, the control unit 280 may control the air conditioner to lower the room temperature when the user's body temperature is higher than the reference body temperature, and to raise the room temperature when the user's body temperature is lower than the reference body temperature.

On the other hand, when a plurality of terminals 100 are located close to the automobile 200, the communication connection between the automobile 200 and the plurality of terminals 100 may be a problem. In addition, in a state in which the communication between the automobile 200 and the terminal 100 is connected, a problem may arise due to a communication connection attempt of the other terminal 100. [

In this case, the control unit 280 may control the communication unit 210 to form a communication channel with the first terminal 100a having a higher priority based on the connection request order. That is, a communication channel is formed with the first terminal 100a which first tried to connect among a plurality of terminals 100 that transmitted and received a connection signal to the automobile 200. This is a method of forming a communication channel without inputting a separate pin code, which is advantageous in that the process of forming a communication channel of an automobile is simple and the time required is short and it is convenient to use.

At this time, if the controller 280 forms a communication channel with the first terminal 100a, the controller 280 may control the communication unit 210 to stop responding to the connection signal of the other terminal 100b. This prevents confusion of control of the display unit 270 due to the connection between the automobile 200 and the plurality of terminals 100a and 100b and prevents the setting of the user from being changed by another person.

Of course, the present invention can simultaneously form a plurality of communication channels in response to connection signals with other terminals 100b even after forming a communication channel with the first terminal 100a.

The control unit 280 receives the PIN code from the plurality of terminals 100 and compares the received PIN code with a PIN (Personal Identification Number) code stored in the memory 240. When the PIN code is received, The communication unit 210 may control the communication unit 210 to form a communication channel with the first terminal 100a having a predetermined priority. In this case, the memory 240 can store the PIN code of the communication unit 210 and the connection priority order of the terminal 100.

Specifically, the control unit 280 controls the communication unit 210 to transmit a PIN code request signal to a plurality of terminals 100 that have transmitted a connection signal. The control unit 280 compares the PIN code transmitted from the plurality of terminals 100 with the PIN code stored in the memory 240 and determines a priority order among the terminals 100 having the same PIN code.

Accordingly, the automobile 200 forms a communication channel with the first terminal 100a having the highest priority. On the other hand, the communication unit 210 does not respond to terminals whose PIN codes do not match.

Such a communication channel forming method is advantageous in that the display part is prevented from being controlled by unauthorized connection of other terminals because a PIN code is required for forming a communication channel.

That is, when the wearable arm is moved while the user wears the smart band 100c, the amount of exercise and calorie of the user can be measured through the motion sensor 132.

Meanwhile, when the user moves the worn arm of the smart band 100c in a state where the power of the smart band 100c is turned off, the motion of the user is sensed through the motion sensor 132 and the power of the smart band 100c is turned on .

The smart band 100c may include an optical sensor 133. [ In this case, the optical sensor 133 senses the amount of change in the transparency of the skin according to the blood flow or the heartbeat flowing in the user's arm. The smart band 100c can measure a user's heart rate and blood pressure using the amount of change in transparency of the skin according to the sensed blood flow volume or heart rate.

Referring to FIG. 3 (d), the wearable device 100d (hereinafter, referred to as "smart earphone") of the earphone type can be used while being worn on the wearer's ear.

The smart earphone 100d may include a main body 345, a cable 343, and a wearing portion 341. [ Various electronic components are built in the main body 345 and the wearing portion 341.

The main body 331 may be provided with an operation module, a microphone, an interface unit, and a power supply unit.

The operation module generates a control signal for controlling the operation of the terminal 100 in response to a user input, converts the generated control signal into an electrical signal, and provides the electrical signal to the mobile terminal.

The microphone may be implemented in a form suitable for receiving a user's voice, other sounds, and the like. The microphone converts the acoustic signal input from the user into an electrical signal and outputs the electrical signal. On the other hand, the microphone may be disposed on the cable 343.

The interface unit can be used as a path for exchanging data with an external device. The power supply unit is a battery for supplying power to the smart watch 100a and may be detachably coupled to the main body 331 for charging or the like.

The cable 343 electrically connects the main body 345 and the wearing portion 341.

The wearing portion 341 is worn on both ears of the user. The wearing portion 341 may include an acoustic output module and an optical sensor.

The sound output module may be implemented in the form of a receiver or a speaker. The sound output module converts an electric signal applied from the mobile terminal 100 into a sound signal and outputs the sound signal. Accordingly, the user can listen to the voice signal of the other party in the call or the multimedia signal of the multimedia being reproduced through the sound output module of the smart earphone 100d.

The smart earphone 100d may include a sensing unit 130. [ The sensing unit 130 included in the smart earphone 100d is as described with reference to FIG.

The smart earphone 100d may include an optical sensor 133. [ In this case, the light sensor 133 senses the amount of change in transparency of the skin depending on the blood flow or the heartbeat flowing in the user's ear. The smart earphone 100d can measure the heart rate and blood pressure of the user by using the amount of change of the transparency of the skin according to the detected blood flow or heartbeat.

4 is a flowchart illustrating an operation of a vehicle according to the first embodiment of the present invention.

Referring to FIG. 4, the controller 280 communicates with the terminal 100 (S410). At this time, Bluetooth communication can be used for communication with the terminal 100. In addition to the Bluetooth method, the control unit 280 may control the operation of the wireless communication system such as Wi-Fi Direct, Radio Frequency Identification (RFID), Infrared Data Association (UDA), Ultra Wideband (UWB), ZigBee, A communication method can be used.

In a state where the terminal 100 is communicatively connected, the controller 280 performs authentication of the terminal 100 (S420). When a plurality of terminals 100 are located close to the automobile 200, communication between the automobile 200 and the plurality of terminals 100 may be a problem. In addition, in a state in which the communication between the automobile 200 and the terminal 100 is connected, a problem may arise due to a communication connection attempt of the other terminal 100. [

In this case, the control unit 280 may control the communication unit 210 to form a communication channel with the first terminal 100a having a higher priority based on the connection request order. That is, a communication channel is formed with the first terminal 100a which first tried to connect among a plurality of terminals 100 that transmitted and received a connection signal to the automobile 200. This is a method in which a communication channel is formed without inputting a separate pin code. This is advantageous in that the process of forming a communication channel of the lighting apparatus is simple and the time required is short and the use is convenient.

At this time, when the control unit 280 forms a communication channel with the first terminal 100a, the control unit 280 may control the communication unit 210 so as not to respond to the connection signal of the other terminal 100b. This prevents confusion of control due to the connection between the automobile 200 and the plurality of terminals 100a and 100b and prevents the setting of the user from being changed by another person.

Of course, the present invention can simultaneously form a plurality of communication channels in response to connection signals with other terminals 100b even after forming a communication channel with the first terminal 100a.

When a connection signal is transmitted from a plurality of terminals to the communication unit 210, the control unit 280 receives the PIN code from the plurality of terminals 100 and compares the PIN code with a PIN (Personal Identification Number) code stored in the memory 240, The communication unit 210 may control the communication unit 210 to form a communication channel with the first terminal 100a having a predetermined priority. In this case, the memory 240 can store the PIN code of the communication unit 210 and the connection priority order of the terminal 100.

Specifically, the control unit 280 controls the communication unit 210 to transmit a PIN code request signal to a plurality of terminals 100 that have transmitted a connection signal. The control unit 280 then compares the PIN code transmitted from the plurality of terminals 100 with the PIN code stored in the memory 240 and determines a priority order among the terminals 100 having the same PIN code.

Accordingly, the automobile 200 forms a communication channel with the first terminal 100a having the highest priority. On the other hand, the communication unit 210 does not respond to terminals whose PIN codes do not match.

Such a communication channel forming method is advantageous in that the display part is prevented from being controlled by unauthorized connection of other terminals because a PIN code is required for forming a communication channel.

In a state where the authentication of the terminal 100 is completed, the control unit 280 receives user body information from the terminal 100 (S430). Here, the body information includes blood flow volume, blood pressure, heart rate, pulse rate, and body temperature of the user.

When receiving the user's body information or the motion information of the terminal 100 from the terminal 100, the controller 280 determines the user's body state (S440).

If the control unit 280 determines that the user's body is abnormal based on the input data, the control unit 280 may control the display unit 270 to output information indicating that the operation is inappropriate, in the form of text or voice.

Specifically, the controller 280 controls the display unit 271 to output an already stored image if the inputted pulse rate is out of the range of the reference heart rate or the reference pulse rate through the input body information.

The control unit 280 controls the sound output unit 272 to output the already stored alarm sound when the inputted pulse rate is out of the range of the reference heart rate or the reference pulse rate through the inputted body information.

For example, the control unit 280 may stop the vehicle if the operation is inappropriate due to a user's physical anomaly based on the input data.

Specifically, when the inputted pulse rate is out of the range of the reference heart rate or the reference pulse rate, the control unit 280 controls the driving unit 260 to stop the automobile.

The control unit 280 controls the sound output unit 272 to output the already stored alarm sound when the inputted pulse rate is out of the range of the reference heart rate or the reference pulse rate through the inputted body information.

If the control unit 280 determines that the user's body temperature abnormality is determined based on the input data, the control unit 280 may control the display unit 270 to output information indicating that the operation is inappropriate, in the form of text or voice.

In addition, if the controller 280 determines that the user's body temperature is abnormal based on the input data, the controller 280 can control the air conditioner of the vehicle.

Specifically, the control unit 280 may control the air conditioner to lower the room temperature when the user's body temperature is higher than the reference body temperature, and to raise the room temperature when the user's body temperature is lower than the reference body temperature.

If the user body information is not received from the terminal 100 in step S430, the controller 280 performs general automobile control (step S460).

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be construed as limiting the scope of the invention as defined by the appended claims. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention.
