In addition, the present invention by using the solar and wind energy as the power source of the outdoor display device, it is possible to save the existing resource energy, thereby reducing the cost of the power energy.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention.

Hereinafter, an outdoor display apparatus using solar and wind energy as power sources will be described with reference to FIG. 1.

As shown in FIG. 1, the outdoor display device using the solar and wind energy as a power source includes a solar measuring unit 100, a wind measuring unit 200, a power generation unit 300, a battery unit 400, and a display. A portion 500 is included.

Accordingly, the outdoor display device obtains solar energy through the solar measuring unit 100, obtains wind energy through the wind measuring unit 200, and obtains the solar energy obtained by the power generation unit 300. And converts wind energy into electrical energy.

As such, the electrical energy converted from the solar and wind energy is provided as a power source of the outdoor display device. In the electrical energy provided at this time, when there is an excess even when used as a power source of the outdoor display device, the surplus electrical energy remaining in the battery unit 400 is stored. Accordingly, the solar measuring unit 100 and the wind measuring unit 200 are unable to obtain sunlight and wind energy due to an external condition such as a cloudy day or no wind, and thus the power generation unit 300. When it is unable to convert the electrical energy from the solar and wind energy, and provides the surplus electrical energy stored in the battery unit 400 as a power source to the outdoor display device.

Therefore, even when an unexpected external condition such as a cloudy day or a wind does not occur, the outdoor display device always maintains the on state of the display unit 500 regardless of such external condition, and delivers it to many people. Delivers an advertising message.

Hereinafter, the brightness control system 510 located in the display unit 500 that can adjust the brightness of the display apparatus 500 according to external brightness will be described in detail with reference to FIG. 2.

As shown in FIG. 2, the brightness control system 510 of the outdoor display apparatus includes a sensing unit 512, a control unit 514, a storage unit 516, and a wireless communication unit 518.

The sensing unit 512 of the present invention continuously measures the external brightness value of the display unit 500. For example, when the sensing unit 512 measures the external brightness of the display unit 500 during the day, an external brightness value of 100 may be obtained. Alternatively, when the sensing unit 512 measures the external brightness of the display unit 500 at night, an external brightness value of 0 may be obtained.

Similarly, different external brightness values are measured according to the time or situation in which the sensing unit 512 measures the external brightness value of the display unit 500.

The sensing unit 512 preferably includes a CDS sensor which is a photosensor. The CDS sensor is a cadmium sulfide sensor, and refers to a semiconductor photo sensor using a photoconductive effect in which a resistance value decreases when exposed to a light source.

The controller 514 of the present invention receives the external brightness value measured by the sensing unit 512 and compares the received external brightness value with a reference external brightness value in a specific situation previously stored in the storage unit 516. The external situation of the display device is determined.

For example, the sensing unit 512 receives an external brightness value of 20 lx from the sensing unit 513 and of the display unit 500 corresponding to an external brightness value of 20 lx stored in the storage unit 516. According to the table that the exterior is 'dawn', it is determined that the exterior of the display unit 500 is dawn based on an external brightness value of 20 lx measured by the controller 514.

Thereafter, the controller 514 adjusts the output voltage of the display unit 500 of the display device based on the determination result.

For example, when the external brightness value is 200 lx, the display unit 500 turns off the output voltage, and when the external brightness value is gradually measured, the brightness value of the display unit 500 is greater than the measured external brightness value. The output voltage of the display unit 500 is adjusted to measure 10 to 20 lx or more.

Therefore, when the controller 514 measures that the external brightness of the display unit 500 is dark, when the output voltage of the display unit 500 is decreased or when the external brightness of the display unit 500 is measured, By increasing the output voltage of the display unit 500, the brightness of the outdoor display is controlled to correspond to the external brightness of the display unit 500. Accordingly, there is an effect that can save the power source supplied to the display unit 500 of the outdoor display device.

The storage unit 516 of the present invention controls the brightness of the display unit 500 to maintain a predetermined brightness or more in response to the external brightness according to the external brightness value of the display unit 500. The storage unit 516 stores reference external brightness values for an external situation of the display unit 500 such as morning, midday, cloudy day, night, and dawn.

The wireless communication unit 516 of the present invention transmits the external brightness value measured by the sensing unit 512 and the output voltage value of the display unit 500 controlled by the control unit 514 to the outside in real time through wireless communication. . Such wireless communication is preferably used infrared communication and RFID communication method.

As a result, the present invention can flexibly control the brightness of the display device corresponding to the external brightness. In addition, by transmitting the control result in real time to the administrator in charge of the display device, it is possible to provide high user convenience.

Hereinafter, a brightness control method of an outdoor display device according to an embodiment of the present invention will be described in detail with reference to FIG. 3.

As shown in FIG. 3, in the brightness control method of the outdoor display device of the present invention, the sensing unit 512 measures an external brightness value of the display unit 500 of the outdoor display device (S610). The sensing unit 512 measures an external brightness value of the display unit 500 with respect to the display unit 500 of the outdoor display device in a power-on state. At this time, the external brightness value measured by the sensing unit 512 may be measured in various values according to the situation such as midday, cloudy day, night, dawn.

The controller 514 receives an external brightness value measured by the sensing unit 512 and adjusts an output voltage of the display unit 500 in response to the external brightness value (S620).

For example, the controller 514 turns off the output voltage of the display unit 500 during the day when the sun rises, and charges the storage battery with the voltage generated by the power generator 300.

When sunset begins, the controller 514 increases the output voltage of the display unit 500 to a maximum voltage that can be output. After that, when the perfect sunset state is harmless, the output of the display unit 500 to maintain the brightness value of about 5 to 10% higher than the external brightness value of the display unit 500 By gradually lowering the voltage, power loss can be minimized by maintaining a constant brightness of the display unit 500.

Afterwards, when the sunrise starts, the outside of the display unit is not completely dark, but as the day becomes brighter, the external brightness value of the display unit 500 gradually increases, so that the control unit 514 displays the display unit 500. ) Gradually increase the output voltage.

As a result, when the controller 514 measures that the external brightness of the display unit 500 is dark, the controller 514 lowers the output voltage of the display unit 500 so that the display unit 500 can be made bright even with a small output voltage. Can be controlled.

Alternatively, when the controller 514 measures that the external brightness of the display unit 500 is bright, the controller 514 may control the display unit 500 to be brighter by increasing the output voltage of the display unit 500.

Accordingly, the power source can be saved by flexibly adjusting the brightness of the display unit 500 according to an external brightness situation without wasting the power source supplied to the display unit 500 of the outdoor display device. .

The wireless communication unit 516 transmits the external brightness value measured by the sensing unit 512 and the output voltage value adjusted by the control unit 514 to the outside in real time through wireless communication (S630). Such wireless communication is preferably to use infrared communication or RFID communication method. The wireless communication unit 516 transmits the measured external brightness value and the adjusted output voltage value to a manager in charge of the display unit 500, thereby allowing the manager to check the brightness state of the display unit 500 in real time. Thus, user convenience can be increased.

 As described above, the present invention can efficiently use the power of the display device by controlling the brightness of the display device according to the external brightness of the outdoor display device.

At the same time, the present invention can reduce the manpower consumption according to the management of the outdoor display device by automatically adjusting the brightness of the outdoor display device located in a place where the administrator is difficult to access according to the external brightness of the display.

In addition, it is possible to provide high user convenience by transmitting the brightness control result of the display device to the administrator in charge of the display device in real time.

In addition, the present invention by using the solar and wind energy as the power source of the outdoor display device, it is possible to save the conventional resource energy, thereby reducing the cost of the power energy.

The brightness control system and method of the outdoor display device according to the present invention have been described above.
