Therefore, the embodiments described in the present specification and the configurations shown in the drawings are merely preferred embodiments of the present invention, and are not intended to represent all of the technical ideas of the present invention. Therefore, various equivalents It should be understood that water and variations may be present.

As shown in the drawing, the power supply device receives a signal sent from the controller 110 and controls the battery short circuit means 120 so that the power supplied to the transmission 170 is supplied from either the fuel cell 150 or the battery 160 .

That is, the power supply device is configured to maximize the power efficiency of the driving motor 140 by selectively switching the power source of the transmission 170 to a radio controlled object (for example, an unmanned airplane, an unmanned vehicle, etc.) In the embodiment of the present invention, a detailed configuration is described by employing an aircraft.

Accordingly, the power supply device includes a receiver 130 provided at one side of the radio-controlled object for receiving a signal transmitted by the operation of the radio-controlled device 110, and a receiver 130 installed in the radio- A fuel cell 150 and a battery 160 that alternately supply power to the transmission 170 and have different voltages, and a control unit 170 that controls the rotation speed of the driving motor 140, And a battery short-circuit means 120 for selectively short-circuiting between the battery 160 and the transmission 170 according to a signal received by the receiver 130.

At this time, the battery 160 and the fuel cell 150 are configured to have different voltages, and the battery short-circuiting unit 120 is provided on one side having a relatively high voltage.

That is, in the embodiment of the present invention, since the battery 160 is configured to have a voltage higher than that of the fuel cell 150, the battery short- And a first high current relay 124 for selectively shorting between the battery 160 and the transmission 170 in cooperation with the first electronic switch 122. The first high- So that the electrical connection between the battery 160 and the transmission 170 is selectively short-circuited.

The transmission 170 is configured to control the rotational speed of the driving motor 140 by a signal from the receiver 130.

A diode 180 is provided between the battery 160 and the transmission 170 and between the fuel cell 150 and the transmission 170 to limit the current flowing in one direction.

The diode 180 may include a first diode 182 located between the battery 160 and the transmission 170 and a first diode 182 located between the fuel cell 150 and the transmission 170. [ And a second diode 184 located between the first diode 182 and the second diode 184.

The first diode 182 and the second diode 184 function to allow current to flow only in a direction to supply power to the transmission 170. Therefore, depending on the usage amount of the battery 160 and the fuel cell 150 This action is maintained even when the voltages are reversed with each other so that the power supply to the transmission 170 can be continuously supplied.

The fuel cell 150 having the relatively low voltage of the battery 160 and the fuel cell 150 maintains an electrically connected state with the transmission 170 in the embodiment of the present invention, And a transmission 170 are connected.

The fuel cell 150 supplies power to the transmission 170 when the battery 160 is in a voltage state higher than the battery 160 or when the battery 160 and the transmission 170 are short-circuited by the battery short- do.

A control method of the power supply apparatus configured as above will be described with reference to FIG.

2 is a flowchart showing a control method of a power supply device for a radio-controlled object according to the present invention.

The control method of the power supply device for the radio controlled object according to the present invention controls the power supply of the battery 160 to be supplied to the transmission 170 when the radio controlled object requires a greater force in operation, So that the power of the fuel cell 150 can be supplied to the transmission 170.

To this end, the power supply device includes a signal checking step (S100) for receiving a signal generated by the operation of the radio controller (110) by a receiver (130) provided at one side of the radio controlled object and confirming whether the signal is an electronic switch control signal A signal discrimination step S200 for checking whether the signal is an electronic switch on signal in the case of an electronic switch control signal and a signal discrimination step S200 for checking whether the first electronic switch 122 and the first high current relay A transmission driving step S300 for driving the transmission 170 with the power of the battery 160 or the fuel cell 150 by interlocking the power of the battery 160 or the fuel cell 150, (S400).

The power of the battery 160 is supplied to the transmission 170 during the take-off in which a relatively large force is required as the radio controlled object is adopted as an aircraft, and during the operation in which a relatively small force is required, So that the power of the fuel cell 150 can be supplied to the transmission 170 wirelessly by the operation of the fuel cell 110.

When the controller 110 is operated by the user while the radio-controlled object is stopped, the receiver 130 performs a signal check step S100 to receive a signal sent from the controller 110. [

The signal checking step S100 is continuously performed, and after the signal checking step S100, the signal discriminating step S200 is performed.

The signal discrimination step S200 is a step for checking whether the signal is an electronic switch control signal for controlling the battery short circuit means 120. [

When the signal discriminated in the signal discrimination step S200 is an electronic switch control signal, the receiver 130 turns on the first electromagnetic switch 122, and the first high current relay 124 is connected to the first A transmission driving step S300 for driving the driving motor 140 by the transmission 170 by electrically connecting the battery 160 and the transmission 170 in cooperation with the electronic switch 122 is performed.

The transmission 170 that is supplied with power from the battery 160 by the transmission driving step S300 causes the driving motor 140 to generate rotational power and the signal for controlling the operation of the transmission 170 is transmitted to the receiver 130 , The rotation speed of the driving motor 140 can be controlled, and the radio control target body is taken off according to the operation shown in FIG.

3 is a schematic diagram showing the direction of current when the transmission 170 is operated by the battery 160 in the power supply of the radio controlled object according to the present invention.

The take-off of the radio controlled object can be operated by using a direction key or the like separately provided to the controller 110, and the power supply apparatus according to the present invention performs a function of switching the power source to the drive motor 140.

When the radio controlled object is taking off and is operating on the airplane, a relatively small force is required rather than a force required at take-off so that power can be supplied from the fuel cell 150 having a relatively lower voltage than the battery 160 .

That is, the user generates a signal by operating a switch or the like for turning off the first electronic switch 122 in the controller 110, and the receiver 130 performs a signal discrimination step (S100) The first electronic switch 122 is turned off via the second switch S200.

The first high-current relay 124 is also turned off in conjunction with the operation of the first electronic switch 122 to short-circuit the electrical connection between the battery 160 and the transmission 170, (150) supplies power to the transmission (170).

4 is a schematic diagram showing the direction of current when the transmission 170 is operated by the fuel cell 150 in the power supply of the radio controlled object according to the present invention.

Meanwhile, the fuel cell 150 may further include a sensing unit for sensing the amount of remaining fuel, and the remaining amount of the fuel sensed by the sensing unit may be transmitted to the controller 110 to inform the user.

In this case, it is needless to say that the user can supply the power of the battery 160 to the transmission 170 by operating the manipulator 110 and reversing the operation of the first electronic switch 122.

The configuration of another embodiment of the present invention will be described below with reference to Fig. 5 attached hereto.

5 is a schematic diagram showing a configuration of a second embodiment of a power supply apparatus for a radio controlled object according to the present invention. In addition to the battery short circuit means 120, a fuel cell short circuit means 125 for shorting the power supply of the fuel cell 150 ).

Accordingly, the power supply unit can electrically connect the battery 160 or the fuel cell 150 to the transmission 170 by the user's operation.

For example, in a situation where the voltage of the battery 160 is higher than the voltage of the fuel cell 150 and the amount of usage is increased to be lower than the voltage of the fuel cell 150, a high output is required to the radio controlled object The current of the battery 160 is generally higher than the current of the fuel cell 150, so that a relatively high output and a high output can be obtained.

Therefore, the battery short circuit means 120 and the fuel cell short circuit means 125 are provided at the same time, so that the battery short circuit means 120 and the fuel cell short circuit means 125 can be switched depending on whether a signal sent by the user is a high- So that power is supplied to the transmission 170.

The fuel cell shorting means 125 includes a second electronic switch 126 interlocked with a signal provided from the receiver 130 and a second electronic switch 126 interlocked with the second electronic switch 126, And a second high-current relay (128) selectively short-circuiting between the first high-current relay (170).

The second electronic switch 126 selectively connects the power provided from the fuel cell 150 to the transmission 170 by interlocking with the second high current relay 128 provided between the fuel cell 150 and the transmission 170 .

The fuel cell short circuit means 125 is configured to operate in reverse to the battery short circuit means 120. The fuel cell shorting means 125 short-circuits the electrical connection between the fuel cell 150 and the transmission 170 while the battery short circuit means 120 electrically connects the battery 160 and the transmission 170. [ .

The control method of the configuration of the second embodiment of the present invention will be described below with reference to Figs. 6 to 8 attached hereto.

6 is a flowchart showing a control method of the second embodiment of the power supply device for the radio controlled object according to the present invention.

[

The signal check step S100 is the same as the control method of the first embodiment described above, and the signal discrimination step S200 is very similar within the same technical idea.

That is, in the signal discrimination step S200, it is discriminated whether the signal confirmed to be the electronic switch control signal is the high output drive signal or the general drive signal. In the embodiment of the present invention, the high output drive signal is discriminated using the battery 160 And the general output drive signal is the drive of the transmission 170 using the fuel cell 150. [

If the signal discriminated in the signal discrimination step S200 is a high output driving signal, the battery short circuit means 120 operates to electrically connect the battery 160 and the transmission 170 (step S300) Power is supplied as shown in FIG. 7, and the fuel cell shorting means 125 shorts the electrical connection between the fuel cell 150 and the transmission 170.

On the contrary, if the signal discriminated in the signal discrimination step S200 is a general output drive signal, the fuel cell short circuit means 120 operates to electrically connect the fuel cell 150 and the transmission 170 S300), power is supplied as shown in FIG. 8. At this time, the battery short-circuit means 120 short-circuits the electrical connection between the battery 160 and the transmission 170. FIG.

The electronic switch control signal transmitted from the controller 110 and operated by the user may be classified into a high output driving signal and a general output driving signal. The first electronic switch 122 or the second electronic switch 126, It is possible to select an object to which the power to be supplied to the transmission 170 is supplied.
