Description
BACKGROUND OF THE
The applicant of the present invention has disclosed a Korean Patent Registration No. 10-1191255, which executes a blood glucose measurement application of a smartphone and combines a plug of a blood glucose measurement module into a socket of a smartphone (SlO); Turning on the power of the blood glucose measurement module using the power of the smartphone and performing an internal test (S20); If there is no abnormality in the internal test, if a strip insertion screen is displayed on the smartphone, a test strip is inserted into a strip insertion port of the blood glucose measurement module, and the smart phone displays a strip deterioration check screen, (S30); (S40) of injecting blood into the test strip when a blood injection screen is displayed on the smartphone, displaying a notification screen during blood glucose measurement and calculating a blood glucose measurement result in the blood; And a step (S50) of displaying the blood glucose measurement result and storing the blood glucose measurement result in the smartphone, wherein the blood glucose measurement module comprises a blood glucose measurement module for measuring a blood glucose level contained in the blood absorbed in the test strip And a central processing unit for calculating and transmitting the blood glucose measurement result; A strip insertion port formed in a part of the main body and having a structure capable of inserting the test strip; And a phone plug or a pin plug formed on one end face of the main body and having a structure connectable to a socket of a smartphone, wherein the smart phone includes a display unit and a power supply unit, And an application program capable of processing and managing blood glucose measured data with a socket to which a plug of a module can be coupled. The blood glucose measurement method using a smartphone is disclosed.
However, when a smartphone module such as the blood glucose measurement module is used in combination with a smartphone stereo socket, the smartphone module does not have its own power supply unit, and thus receives power from a smart phone. Specifically, when a smartphone sends a voice signal (a waveform of a + voltage or a - voltage), the smart phone processes it and converts it into a usable power source. However, since the amplitude (voltage) of the voice signal that can be output to the maximum level of the smartphone differs from product to product, in some smartphone, the operation is not performed due to the voice signal that the smartphone module is not sufficient for power supply .
In order to solve this problem, the battery is installed in the inside of the smartphone module. In this case, the power supply problem can be solved, but the battery consumption is high due to the continuous power supply.
In order to solve the above problems, the present inventors have found that when the smartphone module is inserted into the smartphone, the power is automatically applied, the power is automatically shut off when the smartphone module is separated from the smartphone, and the battery consumption of the smartphone module is reduced To develop a smartphone module that has an automatic power control function that can be controlled by the user.
An object of the present invention is to provide a smartphone module having an automatic power control function in which power is automatically applied when a smartphone module is inserted into a smartphone and the power is automatically turned off when the smartphone module is separated from the smartphone .
It is another object of the present invention to provide a smartphone module having an automatic power control function capable of reducing battery consumption of a smartphone module.
The above and other objects of the present invention can be achieved by the present invention described below.
A smartphone module having an automatic power control function according to the present invention is a smartphone module having a stereo jack capable of being coupled to a stereo socket of a smartphone, the smartphone module being characterized in that when the stereo jack of the smartphone module is inserted into a stereo socket of a smartphone, And a control unit for controlling power to be automatically cut off when the stereo jack of the smartphone module is disconnected from the stereo socket of the smartphone. And a battery unit coupled to a predetermined position of the circuit board to supply power to the circuit board.
Here, the controller may determine whether or not the smartphone is connected to the smartphone by controlling the operation of the internal power supply circuit using the output level of the stereo in the stereo socket of the smartphone.
The circuit board includes a circuit in which a power supply circuit confirms a connection state of the smartphone when the smartphone module is connected to the smartphone, and is turned on or off.
The circuit board changes the power mode by observing the output level of the smartphone with the control unit of the smartphone module. The change of the power mode waits in an idle state when the smartphone and the smartphone module are not connected, And enters a communication standby state when the phone and the smartphone module are connected.
The smartphone module further includes a light emitting unit formed at a predetermined position of the circuit board and being lighted by power control of the control unit.
The present invention provides an automatic power control function that automatically applies power when a smartphone module is inserted into a smartphone, automatically cuts off power when the smartphone module is separated from the smartphone, and reduces battery consumption of the smartphone module The present invention provides a smartphone module having the above-described functions.

2 and 3, the smartphone module of the present invention is a device capable of performing various functions in connection with a smartphone. When the
Specifically, when the
For example, the
The circuit diagram of FIG. 3 shows a circuit in which the power circuit DCDC confirms the connection status of the smartphone when the smartphone module is connected to the smartphone and is turned on / off. The smartphone uses the stereo output (the output of the Stereo-R) To turn on / off the internal DCDC (LDO) power device. Here, the DCDC element is ON when the ON / OFF port of the element is at a low level, and is OFF when it is at a high level. That is, when the smartphone module is not connected to the smartphone, the ON / OFF pin (PIN) of the U5 DCDC LDO device turns OFF in the pull-up state of the internal battery power, and the output of U5 is 0V Since the VCC of the module is not applied, the module consumes about 1 or less of the consumption current of the shutdown state of U5. On the other hand, when the smartphone module is connected to the smartphone, the stereo jack J2 is connected to the smartphone, the U5 ON / OFF pin of the pull-up state is lowered to low, VCC is supplied and the smartphone module is powered up.
Also, the power control using the smartphone module according to the present invention may be performed by changing the power mode by observing the output level of the smartphone with the control unit of the smartphone module. For example, when the smartphone module is not connected to the smartphone, the smartphone module waits in the idle state of the lowest power mode, and when the smartphone module is connected to the smartphone, the communication standby Standby " state.
Although the preferred embodiments of the present invention have been described, the present invention is not limited to the specific embodiments described above. It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the appended claims, And equivalents should also be considered to be within the scope of the present invention.
