In addition, it should be noted that the accompanying drawings are only for easily understanding the spirit of the present invention and should not be construed as limiting the spirit of the present invention by the accompanying drawings.

First, a smart controller equipped with a sensor according to the present invention will be described with reference to FIGS. 1 to 6.

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

First, looking at the smart controller having 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, etc. It is configured to contain.

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

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

This 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, and details thereof will be described later.

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

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. It may be configured as a button separate 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 such a biosensor can measure at least one of the user's blood sugar, hemoglobin concentration, heart rate, body temperature, electrocardiogram, cholesterol level, and body fat rate. It is desirable to be configured.

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

On the other hand, the body 100 is formed with a receiving portion for accommodating the sensor, the sensor may be formed to be detachable from the receiving portion, through this, the user can easily replace the sensor corresponding to the matter that needs to be measured according to the situation. It can be configured to be able to.

In addition, the sensor may be formed integrally with the input button unit, specifically, 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) with a sensor.

The control unit is disposed inside the body and 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 environmental information, and simultaneously executes the application preinstalled in the portable terminal. I can.

For example, if the sensor is an electrocardiogram sensor for measuring the user's electrocardiogram, when the user operates the 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 the portable terminal By doing so, the user can measure the electrocardiogram by operating the sensing button once and check his or her current electrocardiogram 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 causes the portable terminal to run the application corresponding to the installed sensor. It would also be possible to have the sensor run.

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

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

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

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

For example, when a user runs an application installed in a portable terminal, an icon for driving a sensor may be displayed on the display of the portable terminal. When the user touches the icon, guide 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 environment information is detected by the driving of the sensor, the control unit transmits the detection result to the portable terminal for processing by the application. Through this, it is output on the display of the portable terminal.

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

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

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

That is, when 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 has not properly seated a finger 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 measuring biometric information or external environmental information of the portable terminal user due to the user's wrong manipulation.

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

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

However, in determining whether a sensor has failed, if the deviation between the values detected by a plurality of sensors is greater than a preset value, in order to prevent a hasty determination of the failure with only one measurement, the control unit restarts the plurality of sensors. It is desirable to configure it to be driven.

Even if the control unit drives the plurality of sensors again, if a difference between a value detected by one sensor and a value detected by other sensors exceeds a preset range, it may be determined that the sensor has failed.

The determination of the presence or absence of a sensor failure based on the measurement result of such a sensor may be performed by the control unit of the 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 equipped 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 device and a speaker, so that when a sensor failure occurs. An effect that can be easily grasped by the user can be expected.

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

Furthermore, when three or more sensors are provided, a warning is not generated due to a failure of one sensor, and the user's biometric information and external environment information are to be grasped using the measured results from two sensors with no abnormality. May be.

It is formed, and the adjacent second positive terminals must be formed spaced apart so as not to be in contact with each other.

The flexible printed circuit board assembly 1200 is mounted on the inner bottom surface 1111 so that one bottom surface is electrically connected to the first contact 1130, and a push button 1300 and a push button 1700 to be described later. It performs the function of transferring the electrical signal generated by the operation of) to the other device connected to the signal input device.

The flexible printed circuit board assembly 1200 may be configured to include a flexible printed circuit board 1210, an ACF film 1220, and a switch member 1230, as shown in FIGS. 12 and 13.

The flexible printed circuit board 1210 has a configuration in which a third contact 1211 corresponding to the first contact 1130 is formed on one lower surface of the flexible printed circuit board 1210, and a connection part 1212, that is, a connector, which is connected to an external device, is formed on the other side.

In particular, the signal input device according to the first embodiment of the present invention is for electrical connection between the first contact 1130 formed in the first housing 1100 and the third contact 1130 of the flexible printed circuit board 1210. ACF (Anisotropic Confuctive Filme) Bonding is used. This ACF Bonding is a bonding method in which electrical conduction is possible up and down using an anisotropic conductive film and insulated to the left and right.

Specifically, when the ACF film 1220 is placed between one bottom surface of the flexible printed circuit board 1210 and the inner bottom surface 1111 of the first housing 1100 and then pressurized while applying heat or the like, the ACF film 1220 ) The first contact 1130 and the third contact 1211 are electrically connected by a conductive ball disposed therein.
