First, referring to FIGS. 1 to 6 , a smart controller having a sensor according to the present invention will be described.

A smart controller with a sensor according to the present invention relates to a smart controller for controlling a portable terminal, and it is possible to control the portable terminal through wired communication with the portable terminal, but controls the portable terminal using wireless communication such as Bluetooth. It is desirable to do

First, looking at the smart controller equipped with a sensor according to the present invention, as shown in FIGS. 1 and 3, the body 100, the input button unit, the sensor, the control unit, the terminal 300, and the LED 400 configured to include

The body 100 is configured to accommodate an input button unit, a control unit, a connector terminal 300, and an LED 400.

The input button unit is disposed on an upper surface or side surface of the body and performs a function of generating a control signal of the portable terminal by a user's manipulation.

The input button unit may include a main button 1000 and at least one auxiliary button 200, and the main button 1000 is a push button 1120 capable of generating a signal by lateral pressing and downward pressing. It is configured to include a push button 1150 capable of generating a signal by, which will be described in detail later.

The auxiliary button 200 is a component provided to change the operation mode of the main button 1000 or to perform a specific function of the portable terminal 10, such an auxiliary button 200 is an operation mode of the main button 1000 That is, it may perform a function for switching to a keyboard mode and a mouse mode, may perform a call and volume control function, and may perform a function of executing a specific application set in advance or controlling the application.

In addition, the input button unit may include a sensing button for driving a sensor to be described later, and the auxiliary button 200 or the main button 1000 may perform the function of the sensing button, and the auxiliary button 200 and the main It may also be configured as a separate button from the button 1000 .

The sensor performs a function of detecting the user's biometric information or external environment information, and may be provided inside the body 100 or may be provided in the sensor module 500 to be described later.

Such a sensor may be a biosensor capable of detecting the user's biometric information, and the biosensor may measure at least one biometric information of the user's blood sugar, hemoglobin concentration, heart rate, body temperature, electrocardiogram, cholesterol level, and body fat percentage. It is desirable to configure

In addition, the sensor may be an eco-sensor for detecting environmental information around the user of the portable terminal, and the eco-sensor may provide at least one environmental information of radiation temperature, ozone concentration, carbon monoxide concentration, carbon dioxide concentration, fine dust concentration, and UV index. It is preferable to be configured to measure .

On the other hand, an accommodating part for accommodating a sensor is formed in the body 100, and the sensor may be detachably formed in the accommodating part, through which the user can easily replace the sensor corresponding to the item that needs to be measured according to the situation. It can be configured so that

In addition, the sensor may be formed integrally with the input button unit, specifically, it may be configured separately from the main button 100 and the auxiliary button 200, or a part of the main button 100, specifically the main button 100 ) It is also possible to configure the upper surface of the sensor.

The control unit is disposed inside the body, receives the detection value of the sensor, and transmits it to the portable terminal.

On the other hand, when the above-described sensing button is provided, when the sensing button is operated, the control unit controls the sensor to detect the user's biometric information or external environment information and simultaneously executes an application pre-installed in the portable terminal. can

For example, if the sensor is an electrocardiogram sensor for measuring the user's electrocardiogram, when the user operates a sensing button, the control unit causes the electrocardiogram sensor to measure the user's electrocardiogram, and at the same time executes an electrocardiogram-related application installed in a portable terminal. By doing this, the user can measure the electrocardiogram by operating the sensing button once and check the current electrocardiogram of the user through the display of the portable terminal.

Furthermore, when the user operates the sensing button, the control unit first checks the type of sensor and then makes the portable terminal run the application corresponding to the installed sensor. It would also be possible to have the sensor actuated.

In addition, in relation to the method of driving the sensor, a method of driving the sensor using an application pre-installed in the user's portable terminal may be considered in addition to the method of driving by the sensing button included in the smart controller as described above.

Such an application should be installed in a portable terminal and configured to perform at least one of a function of controlling driving of a sensor and a function of outputting a detection value of a sensor.

At this time, when the user executes the application installed in the portable terminal and requests the driving of the sensor using the application, the portable terminal transmits the sensor driving signal to the control unit of the smart controller, and the control unit transmits the sensor driving signal based on the received sensor driving signal. to drive the sensor.

Thereafter, when the sensor detects the user's biometric information or external environment information to obtain a detection value, the control unit transfers the obtained detection value to the portable terminal, and the application transmits the detection result, such as the detection value and evaluation. output on the display of the portable terminal.

For example, when a user executes an application installed in a portable terminal, an icon for driving a sensor may be displayed on the display of the portable terminal, and when the user touches the corresponding icon, guidance information for sensing is displayed on the display. At the same time, the portable terminal transmits the driving signal of the sensor to the control unit of the smart controller.

The control unit drives the sensor based on the driving signal of the sensor, and when the user's biometric information or external environmental information is detected by the driving of the sensor, the control unit transfers the detection result to the portable terminal to perform processing by the application. Through this, it is output on the display of the portable terminal.

On the other hand, in the smart controller equipped with a sensor according to an embodiment of the present invention in order to ensure accurate measurement of the sensor, when the user operates the sensing button, the sensor detects the user's biometric information or external environment information multiple times, and the sensor The control unit may be configured to drive the sensor again when the deviation between the values detected a plurality of times by is greater than a preset value.

For example, if the sensor is a biosensor for detecting the user's body temperature by contacting the user's finger, if the user does not properly place the finger on the sensor or does not seat the finger during the operating time of the sensor, the sensor The user's body temperature cannot be properly detected.

In order to prevent this problem, the sensor detects the user's body temperature a plurality of times within a preset time.

That is, if the sensor is set to measure the user's body temperature three times within a preset time, and the first body temperature, the second body temperature, and the third body temperature continuously measured by the sensor are 42.3 degrees, 36.9 degrees, and 36.8 degrees, respectively, The control unit determines that the user's finger is not properly seated on the sensor and causes the sensor to detect the user's body temperature again.

Through this, it is possible to ensure the accuracy of measurement of biometric information of a portable terminal user or external environmental information due to user's wrong operation.

Furthermore, in order to prevent errors in measuring biometric information or external environmental information due to sensor failure, a smart controller equipped with a sensor according to an embodiment of the present invention may include a plurality of sensors, preferably three or more sensors. .

When the deviation between the values detected by the plurality of sensors is smaller than the preset value, the average value of the values detected by the plurality of sensors may be output as the detection result, and the deviation between the values detected by the plurality of sensors is the preset value. If it is greater than the number of sensors, the control unit may determine that a failure has occurred in at least one of the plurality of sensors.

However, in order to prevent hasty determination of failure with only one measurement in determining whether a sensor is out of order, if the deviation between the values detected by a plurality of sensors is greater than a preset value, the control unit re-checks the plurality of sensors. It is desirable to configure to drive.

Even if the control unit drives the plurality of sensors again, if a difference between the detected values of one sensor and the detected values of the other sensors by more than a preset range occurs, it may be determined that the corresponding sensor is out of order.

Determination of failure of the sensor based on the measurement result of such a sensor may be performed by a control unit of a smart controller or may be performed by a portable terminal.

In this case, when the application of the portable terminal determines that the value detected by the sensor is out of a preset range, the portable terminal may transmit warning information to the control unit.

In particular, the smart controller with a sensor according to an embodiment of the present invention may further include a warning unit that operates based on the above-described warning information, and this warning unit is composed of at least one of a light emitting element and a speaker, so that when a sensor failure occurs An effect that can be easily understood by the user can be expected.

In addition, it will be possible to deliver a warning message to the user using a display, speaker, etc. provided in the portable terminal through a related application installed in the user's portable terminal without including a separate warning unit in the smart controller.

Furthermore, in the case of having three or more sensors, a failure of one sensor does not cause only a warning, and it is configured to grasp the user's biometric information and external environment information using the measured results from two sensors without abnormalities. may be
