As a wearable terminal mounted on a part of the body has been developed, a sensing module for identifying a breathing state using the same has been studied. However, the small size of the wearable terminal itself, a lot of movement in the state attached to the body and the specific measurement of the mounted body region has a disadvantage that difficult measurement.

Accordingly, the present invention is to provide a watch type terminal having a sensing unit consisting of a light receiving sensor and a light emitting element spaced apart to maintain a specific distance for accurate measurement of the biological signal.

The first and second light emitting devices 312a and 312b output green light. The green light output from the first and second light emitting devices 312a and 312b is reflected by the skin and received by the light receiving sensor 311.

Light has a shorter wavelength, and transmits a longer wavelength. In order to measure a biosignal (heart rate change) as a PPG sensor, the output light must reach a skin depth where blood vessels are located so that blood flow change can be measured. However, when light reaches more than the skin adapter where the blood vessel is located may be absorbed by the tissue or bone. In general, since the wrist of the body is deeper from the finger to the blood vessel, the transmission of green light is suitable for reaching the blood vessel.

The sensing unit according to the present embodiment includes a red light emitting device and an IR device for oxygen saturation measurement. The red light and the IR have high absorption rates of hemoglobin (Hb) and oxygen hemoglobin (HbO2), and have different absorption rates. Accordingly, the oxygen saturation is calculated through the ratio of the absorption rate of oxygen hemoglobin (HbO ₂ ) to the sum of the absorption rate of oxygen hemoglobin (HbO ₂ ) and the absorption rate of hemoglobin (Hb).

Since absorption rates of the red light and the IR light of the oxygen hemoglobin (HbO 2) and the hemoglobin (Hb) are different, graphs of these ratios are also formed differently.

Alternatively, referring to FIG. 2B (d), when all hemoglobin is bound to oxygen (O 2), the graph showing the oxygen saturation is substantially the same as the graph showing the light absorption according to the wavelength of the oxygen saturation (HbO 2). Is formed. This diameter means that all oxygen and hemoglobin are combined with each other and oxygen can be delivered to the whole body. 2B and 2B show graphs showing different degrees of oxygen saturation.

Therefore, the oxygen saturation can be measured more accurately.

6A is a flowchart illustrating a control method of a mobile terminal using an oxygen saturation degree sensed by the sensing unit of the present invention, and FIG. 6B is a conceptual diagram illustrating the control method of FIG. 6A.

Referring to FIG. 6A, the controller measures oxygen saturation using the sensing unit for a specific time (S11). For example, the controller controls the sensing unit to measure the oxygen saturation at a predetermined period when the sensing unit detects that the watch type terminal 100 is worn on the user's wrist. Alternatively, the control unit may control the sensing unit to measure the oxygen saturation level during a specific time of day, for example, during a sleep time, while sensing an abnormal state of the body by another sensor and detecting an exercise state.

The control unit analyzes the presence of an apnea state using the oxygen saturation degree (S12). Sleep apnea is the stopping of breathing during sleep, the lack of oxygen supplied to the brain, the autonomic nervous system can become sensitive, and sleep deprivation. In the sleep apnea stage, the oxygen supply is insufficient, so the oxygen saturation is lowered. Therefore, when the calculated oxygen saturation falls below a specific reference value, the controller determines that the apnea state is apnea.

For example, the apnea state and the number of occurrences of the apnea state that occur during sleep time may be determined, and information related to the occurrence and the number of occurrences of the apnea state may be stored by the memory 170.

When the apnea state (or the apnea state lasts for a certain time or lasts a certain time) or occurs a certain number of times, the controller switches the watch type terminal 100 to a warning mode and displays a warning mode (S13). ).

Referring to FIG. 6B, when the display unit of the mobile terminal interlocked with the watch type terminal 100 is activated, the controller switches the mobile terminal to the warning mode. In addition, the display unit of the mobile terminal 100 outputs the warning window 410. The warning window 410 may include notification information indicating that the apnea state is changed in the multi-section and switching to the warning mode (S13).

The control unit controls the mobile terminal or the watch type terminal based on the warning mode when confirming the switching of the warning mode. However, when the switch of the warning mode is rejected based on the touch input applied on the notification information 410, the controller executes the watch type or the mobile terminal regardless of the apnea state.

One region (status bar) of the display unit of the watch type terminal or the display unit of an external device interworking with the watch type terminal 100 corresponds to a warning mode when the user of the watch type terminal 100 is apnea in multiple sections. The graphic image 503 may be output.

The controller may switch the warning mode to an inactive state based on a touch input applied to the display unit. When the warning mode is deactivated, the mobile terminal and the watch type terminal may be controlled regardless of the apnea state of the user.

The display unit includes at least one screen information including driving state information based on a dragging touch applied from the status bar, and the screen information includes an image bar 420 corresponding to the warning mode. Although not illustrated in detail, additional information regarding an apnea state may be included on the image bar 420. For example, it may include the time when the apnea state, the delay time of the apnea state, pattern information and the like.

Accordingly, the user can recognize that the apnea state occurs during the sleep time (or during a specific time) by the graphic image 503 displayed on the status bar, and thus can adjust the physical condition of the body by himself.

In addition, based on the additional touch input applied to the graphic image 503, specific information regarding the apnea state may be provided, and the watch type terminal and the mobile terminal are controlled by the warning mode, so that the health state may be determined.

However, the control method according to the present embodiment may also be implemented by the watch type terminal 100. Therefore, when the apnea state occurs for a specific time, the watch type terminal 100 may switch the watch type terminal 100 to a warning mode instead of transmitting a radio signal to an external device.

Hereinafter, when the apnea occurs, the control method of the mobile terminal performing wireless communication with the watch type terminal 100 and / or the watch type terminal 100 will be described.

7A and 7B are conceptual views illustrating a control method of a watch type terminal and / or a mobile terminal wirelessly communicating with the watch type terminal according to an embodiment of the present invention.

Referring to FIG. 7A, the controller 180 collects sleep state information using the sensing unit (S21). Here, the sleep state information may be formed through the occurrence, cycle, frequency, time, etc. of the sleep apnea state calculated through the oxygen saturation level detected by the sensing unit.

The controller 180 collects data of the current date (S22). For example, the data of the current date may include schedule information stored in the current date, weather information related to the current date, information related to the current date and received from a server or an external device.

The controller 180 determines whether alarm information and / or schedule information set by the collected information is present (S23). When the alarm information related to the wake-up time of the current date is collected, the controller 180 compares the appropriate weather time calculated based on the sleep state information with the scheduled weather time based on the alarm information (S24), and outputs an alarm. The time is adjusted (S25).

In adjusting the output time of the alarm, the controller 180 may analyze and determine the collected history information and schedule information of the user.

On the other hand, if there is no alarm information and schedule information, the controller 180 calculates an appropriate wake up time based on the collected sleep state information (S26). The controller 180 outputs an alarm after a proper sleep time (S27).

7B shows measured sleep levels. The sleep level represents a deep level of sleep, and the lower the level, the deeper the sleep. When the level 1 or more, the muscle activity is stopped but the REM sleep state in which the brain activity is maintained. When the alarm output time expected by the original user's setting is the first time t1, the alarm sounds when the user is in a deep sleep state.

In this case, the controller 180 may adjust the alarm time based on the sleep pattern calculated by the oxygen saturation degree. For example, the controller 180 may control to output an alarm at a second time t2 when the REM sleep state is reached when the estimated time of the alarm output corresponds to a deep sleep state based on the measured oxygen saturation degree. .

When performing wireless communication with an external device, the controller 180 transmits sleep information according to the oxygen saturation degree to the external device. The external device may adjust the output time by comparing the sleep information and the store alarm information. That is, the external device controls the output unit including the display unit to output the alarm information 510 at the adjusted output time second time t2.

According to the present embodiment, the sleep state information may be collected by the oxygen saturation level, and the output time of the alarm may be changed at a time when the user is apt to wake up. Accordingly, it is possible to help wake up at an appropriate time based on the sleep state of the user.

8A to 8C are conceptual views illustrating a control method of providing guide information based on stored information and sleep state information.

8A to 8C illustrate an example of an external device for wireless communication with the watch type terminal 100 of the present invention, the control method is substantially the same as the watch type terminal 100 of the present invention.

Referring to FIG. 8A, schedule information may be stored in a memory of the external device or a memory 170 of the watch type terminal 100 based on a control command of a user. FIG. 8A (a) shows first screen information 501 including the schedule information.

The controller 180 may calculate an appropriate sleep time of the user based on the sleep state information stored in the memory 170. The controller 180 may output first guide information 520 for guiding sleep based on a current time and sleep state information and schedule information stored in the memory 170.

The guide information 520 may be displayed on the display unit 151 of the watch type terminal 100, or may be displayed on a display unit of an external device that communicates wirelessly with the watch type terminal 100 as shown in the drawing. . In this case, the guide information 520 may include a control image 520a that receives a touch input for setting a new alarm. Although not illustrated in detail, when a touch input is applied to the control image 520a, an application for setting an alarm may be executed.

The guide information 520 may be implemented not only visual data but also auditory data or vibration.

For example, the guide information 520 may include information on time when sleep should be started by comparing a proper sleep time with the current time, or information on time when the user can go to bed and text related to a stored schedule. And / or an image or the like.

Referring to FIG. 8B, the external device performs wireless communication with the watch type terminal 100 including the sensing unit, and transmits sleep state information collected to a preset specific external device or an external device located within a specific range. do. The external device that receives the sleep state information may correspond to an external device of a user other than the user of the watch type terminal 100.

The controller 180 of the watch type terminal 100 transmits the sleep state information to a peripheral external device when the sleep state information does not correspond to a normal sleep state range.

For example, when it is detected that the apnea state is detected by the snoring or the apnea state is frequently detected, specific information is transmitted to the mobile terminal of the user adjacent to the watch type terminal 100.

The external device that receives the sleep state information by wireless communication with the watch type terminal 100 outputs second guide information 530 based on the sleep state information. The second guide information 530 may be visual data displayed on a display unit of the mobile terminal, or may be implemented as auditory data or vibration. When the second guide information 530 corresponds to the visual data, the second guide information 530 may include a control image 530 ′ for providing additional information.

Additional guide information may be output based on a touch input applied to the control image 530 ′. The first additional guide information 530a includes information related to the sleeping posture of the user of the watch type terminal 100, and the second additional guide information 530b extracts information stored in the watch type terminal 100. Provide analysis results. For example, the second additional guide information 530b includes guide information for refraining from eating the corresponding food while providing food intake information stored in the watch type terminal 100. Meanwhile, the third additional guide information 530c provides an analysis result by using sensing information sensed by a sensor unit mounted on an external device that outputs the guide information. For example, the third additional guide information 530c may include guide information for adjusting the illumination through the illumination sensed through the illumination sensor of the external device.

Referring to FIG. 8C, additional guide information according to another embodiment will be described. The external device is set to wirelessly communicate with the watch type terminal 100. When the external device receives sleep state information from the watch type terminal 100, the external device may output guide information 530 including the control image 530 ′ to the display unit.

The watch type terminal 100 may transmit the guide information together with the sleep state information to the external device. For example, the watch type terminal 100 may transmit the health state information of the user together with the sleep state information to the external device. Accordingly, the external device outputs fourth additional guide information 530d including the sleep state information and the health state information. Accordingly, the user of the external device may take appropriate measures on the user through the fourth additional guide information 530d.

Meanwhile, the external device displays fifth additional guide information 530e recommending a preset function based on the sleep state information. For example, the set function may correspond to a music playing function to help sleep. The controller 180 of the watch type terminal 100 may transmit a control command for executing a specific function when transmitting the sleep state information. Accordingly, before the user of the external device wakes up, a specific function to help the sleep state is executed based on the control command.

According to the present embodiments, as well as providing the guide information directly to the user wearing the watch type terminal 100, it is possible to provide the guide information through an external device capable of wireless communication, the watch in the sleep state The type terminal 100 may help the user sleep by providing information to others without waking the user.

When a specific function is executed by the execution screen 500a, a first warning window 544 corresponding to the specific function is displayed. The first warning window 544 may include a message for checking whether the specific function is executed, but is not limited thereto. The first warning window 544 includes text for explaining why the execution is restricted while limiting the execution of the specific function. It can only contain text to warn you to stop executing a particular function, and the specific function can be executed as is. After the first warning window 544 is output, a control window of another function that can be executed together with the specific function may be displayed.

Meanwhile, the watch type terminal 100 and the external device may output a second warning window 545 based on the execution of a specific function in the warning mode. The second warning window 545 may include a guide message for executing a function that can be executed together with the specific function. For example, the second warning window 545 may include text for guiding execution of a music playing application.

When the same application is activated, the external device or the watch type terminal 100 may selectively output the first warning window 545 or the second warning window 545 based on the executed function and the condition of the executed function. Can be.

Referring to FIG. 10B, when a specific change is detected by the external device or the watch type terminal while the warning mode is being executed, a third warning window 546 is output. The third warning window 546 may be displayed on the watch type terminal 100 or the external device. The specific change may correspond to a sudden change in the acceleration state. The third warning window 546 may include a message to determine that an accident occurs when a signal input is not applied based on a sudden change.

After the third warning window 546 is output, if the requested signal input is not applied, the fourth warning window 547 may be displayed. The fourth warning window 547 includes a guide message for transmitting the information about the specific change to another external device. In this case, the information about the specific change may be transmitted to an external device or a preset external device which frequently performs wireless communication with the external device or the watch type terminal.
