Further, the terms "part," "module," and the like described in the specification mean units for processing at least one function or operation, and may be implemented by hardware, software, or a combination of hardware and software.

Throughout the specification, the term "initial state" means that the heat collecting housing or heliostat is oriented toward the east where sunrise begins.

FIG. 1 illustrates a configuration of a heli start control apparatus using a hybrid solar tracking apparatus according to an embodiment of the present invention.

1 according to an exemplary embodiment of the present invention includes a heat collecting housing 100 and a heat sensor surrounding the heat collecting housing 100 to sense sunlight to track the position of the sun and to collect heat from the heat collecting housing 100, A sun position calculation unit 300 for calculating the position of the sun from the sunlight sensed through the illuminance sensor, a heliostat 400, A helio start control unit 500 for controlling the start 400 and an absorber (not shown in FIG. 1) for receiving solar radiation energy from the heliostat 400.

The solar position tracking unit 200 includes a solar light sensing unit 210, an analog-to-digital converter 220, a drive pulse calculating unit 230, and a motor driving unit 240.

The solar light sensing unit 210 is composed of four light intensity sensors for sensing sunlight around the heat collecting housing 100 and sends the output voltage value of the light intensity sensor to the analog-digital converter 220.

FIG. 2 illustrates a heat collecting housing of a helicoid control device using a hybrid solar tracking device according to an embodiment of the present invention.

2, the heat collecting housing 100 is formed in a predetermined column shape having a solar heat collecting portion (or a solar light collecting portion) And is configured to sense sunlight in each direction.

The illuminance sensor includes a first illuminance sensor 211 for detecting sunlight from the east side of the heat collecting housing 100, a second illuminance sensor 212 for sensing sunlight from the west, A third illuminance sensor 213 and a fourth illuminance sensor 214 for sensing sunlight in the north.

The first illuminance sensor 211 and the second illuminance sensor 212 are used to track the azimuth angle of the sun while the third illuminance sensor 213 and the fourth illuminance sensor 214 are used to track the altitude of the sun do.

Referring again to FIG. 1, the analog-to-digital converter 220 converts the output voltage value of the illuminance sensor from an analog signal to a digital signal and transmits the digital signal to the drive pulse calculating unit 230.

The driving pulse calculating unit 230 generates a pulse for driving the motor according to the output voltage value inputted through the analog-to-digital converter 220 and transmits the generated pulse to the motor driving unit 240. The driving pulse calculating unit 230 calculates a driving pulse A comparing unit 232 and a pulse generating unit 233.

The average value calculator 231 calculates the average value of the output voltage values of the first and second illuminance sensors 211 and 212 or the average value of the output voltages of the third and second illuminance sensors 213 and 214 .

The average voltage value means an average value of sunlight sensed by the illuminance sensor in the east-west direction and the south-north direction.

The voltage value comparing unit 232 compares the average voltage value calculated through the average value calculating unit 231 and the previously stored blur threshold value with the output voltage value of each illuminance sensor.

The blur threshold value means an output voltage value of the illuminance sensor in a state in which sunlight can not be condensed. For example, the blur threshold value means an output value of the illuminance sensor in a cloudy weather or a state in which the sun is blocked by clouds.

The pulse generating unit 233 generates a pulse for controlling the heat collecting housing 100 according to the comparison result of the voltage value comparing unit 232 and sends it to the motor driving unit 240.

If the output voltage value of the first illuminance sensor 211 is larger than the blur threshold value and smaller than the average voltage value of the first ambient light intensity sensor 211 and the second ambient light intensity sensor 212 as a result of the average value comparison of the voltage value comparator 232 , It means that the solar light in the east direction in which the first illuminance sensor 211 is located is smaller than the solar light in the west direction in which the second ambient light sensor 212 is located.

Accordingly, a motor drive pulse that can drive the heat collecting housing 100 in the west direction of the second illuminance sensor 212 is generated and transmitted to the motor driving unit 240.

At this time, if the output voltage value of the first illuminance sensor 211 is smaller than the blur threshold value as a result of the average value comparison of the voltage value comparator 232, the heat collecting housing 100 outputs the output voltage The solar array controller 300 generates a return pulse through the sun position calculator 300 and transmits the return pulse to the motor driver 240 so that the heat collecting housing 100 stops the solar heat collection and returns to the initial state.

The process of returning the heat collecting housing 100 to the initial state will be described in detail with reference to FIG.

The motor driving unit 240 drives the azimuth angle motor 241 in the forward or reverse direction according to the pulse generated through the pulse generating unit 233 so that the heat collecting housing 100 is driven by the first illuminance sensor 211 and the second illuminance sensor 212 to the east-west direction.

Further, by driving the altitude angle motor 242 in the normal direction or the reverse direction, the heat collecting housing 100 is controlled in the south-north direction in which the third illuminance sensor 213 and the fourth illuminance sensor 214 are located.

The sun position calculation unit 300 calculates the position of the sun by calculating the pulses per hour of the azimuth motor 241 and the altitude angle motor 242 of the sun position tracking unit 200 and calculates the azimuth angle and altitude angle of the sun An azimuth angle calculation unit 310, an altitude angle calculation unit 320, and a return pulse calculation unit 330. [

The azimuth calculator 310 calculates the total driving angle of the azimuth motor 241 by counting the number of pulses per hour of the azimuth motor 241 and multiplying the counted number of pulses by the driving angle per pulse of the motor to calculate the initial azimuth angle To calculate the current azimuth angle of the sun.

The altitude angle calculator 320 counts pulses per hour of the altitude angle motor 242 and calculates the total drive angle of the altitude angle motor 242 by multiplying the counted number of pulses by the drive angle per pulse of the motor, Add the initial elevation angle to calculate the current elevation angle of the sun.

As shown in FIG. 5, when solar light is incident in the west direction and shadows of the heat collecting housing 100 are generated in the east direction, the first illuminance sensor 211 located at the east side is relatively higher than the second ambient light sensor 212 located at the west side The output voltage value decreases because it detects a small amount of sunlight.

Accordingly, the position of the sun can be tracked by driving the motor in the west direction to make the output voltage values of the azimuth control light intensity sensors, that is, the first and second illuminance sensors 211 and 212 equal to each other.

FIG. 6 shows a case where the shadow of the heat collecting housing 100 is generated in the west direction when sunlight is incident in the east direction as opposed to FIG. 5, and the position of the sun can be traced on the same principle as FIG.

FIG. 8 is a flowchart sequentially illustrating a method of controlling hell start using a hybrid solar tracking apparatus according to an embodiment of the present invention. Referring to FIG.

First, the position of the solar house is tracked (S100), the position of the heat collecting housing 100 is controlled (S200), and the azimuth angle and elevation angle of the sun are calculated (S300). Based on the azimuth angle and altitude angle of the sun, The position of the start is controlled (S400).

In the following, a method of controlling hello start using the hybrid solar tracking device will be described in detail with reference to FIGS. 9 to 12.

FIG. 9 is a flowchart sequentially illustrating a method of tracking a position of a sun according to an embodiment of the present invention.

First, when the first illuminance sensor 211 in the east direction and the second illuminance sensor 212 in the west direction sense solar light through the solar light sensing unit, the first illuminance sensor 211 and the second illuminance sensor 212 And receives an output voltage value (S101).

Then, an average value of the output voltage value of the first illuminance sensor 211 and the output voltage value of the second illuminance sensor 212 is calculated through the average value calculating unit 231 (S102).

If the average value is calculated, the blur threshold value and the average value are compared with the output voltage value of the first illuminance sensor 211 or the output voltage value of the second illuminance sensor 212 through the voltage value comparator 232 (S103, S106).

As a result of the voltage value comparison, if the output voltage value of the first illuminance sensor 211 is larger than the blur threshold value and smaller than the average voltage value (first condition), a forward rotation pulse of the motor is generated through the pulse generation unit 233 (S104) The azimuth motor 241 of the solar locator 200 is driven to move the heat collecting housing 100 toward the second illuminance sensor 212 (S105).

As shown in FIG. 5, the first condition is satisfied when the first illuminance sensor 211 detects relatively less sunlight than the second illuminance sensor 212 located at the west due to the shadow of the heat collecting housing 100.

6, when the first condition is not satisfied, the output voltage value of the second illuminance sensor 212 is compared with the blur threshold value and the average voltage value, and the output voltage value of the second illuminance sensor 212 is (Second condition), a reverse rotation pulse of the motor is generated through the pulse generation unit 233 (S107), and the azimuth motor 241 is driven (S108), if it is larger than the blur threshold value and smaller than the average voltage value.

In this case, if the first condition and the second condition are not satisfied, the heat collecting housing 100 receives the output voltage value through the solar light sensing unit 210, terminates the tracking of the sun position, 100) to the initial state.

The method of tracking the position of the sun using the output voltage values of the third illuminance sensor 213 in the south direction and the fourth illuminance sensor 214 in the north direction through the solar light sensing unit 210 is also the same as that of FIG. .

Thereafter, the forward rotation pulse and the reverse rotation pulse are multiplied by the driving angle per pulse of the azimuth motor 241 to calculate the total normal rotation driving angle and the total reverse rotation driving angle of the azimuth motor 241 (S302).

Thereafter, the rotation angle of the azimuth motor 241 is obtained using the difference between the total forward rotation driving angle and the total reverse rotation driving angle (S303), and the azimuth corresponding to the current position of the sun is calculated by adding the initial azimuth (S304) .

The altitude angle calculation method of the sun is also the same as the azimuth angle calculation method of FIG.

FIG. 11 is a flowchart sequentially illustrating a method for ending a position tracking of a sun according to an embodiment of the present invention.

First, the sunlight is sensed from the first illuminance sensor 211, the second illuminance sensor 212, the third illuminance sensor 213, and the fourth illuminance sensor 214 through the solar light sensing unit 210, (S501).

Thereafter, an average value (azimuth control average voltage value) of the output voltage value of the azimuth control first illumination sensor 211 and the output voltage value of the second illuminance sensor 212 is calculated through the average value calculation unit 231, (Altitude control average voltage value) of the output voltage value of the third roughness sensor 213 and the output voltage value of the fourth roughness sensor 214 (S502).

Thereafter, the voltage value comparison unit 232 compares the end voltage value, the azimuth control average voltage value, and the altitude angle control average voltage value (S503).

In this case, the termination voltage value means the output voltage value of the illuminance sensor between 6:00 PM, which is the start time of the sunset, and 7:00 AM, which is the start time of the sunrise, and may be equal to the blur threshold value.

When the azimuth control average voltage value and the altitude angle control average voltage value are less than the end voltage value as a result of the voltage value comparison, the azimuth motor 241 and the altitude angle motor 242 return pulses (S504). The azimuth angle motor 241 and the altitude angle motor 242 are driven to return the heat collecting housing 100 to the initial state (S505).

If the azimuth control average voltage value and the altitude angle control average voltage value are greater than the end voltage value, the output voltage value is re-inputted through the solar light sensing unit 210 or the sun position tracking is performed as shown in FIG. do.

12 is a flowchart sequentially showing a return pulse calculating method of a motor according to an embodiment of the present invention.

First, the rotation angles of the azimuth angle motor 241 and the altitude angle motor 242 are calculated as a result of subtracting the initial azimuth angle and the initial altitude angle from the final azimuth angle or the final altitude angle of the sun, respectively (S601).

Subsequently, the rotation angle is divided by the azimuth angle motor 241 and the angle of the elevation angle motor 242 to calculate a return pulse (S602). The azimuth angle motor 241 and the altitude angle motor 242 are controlled according to the return pulse The heat collection housing 100 is returned to the initial state.

Returning to FIG. 8, the position control step (S400) of the heliostat explains the azimuth and elevation angle calculation processes of the heliostat through the above Equations (3) to (13) in detail,

12, the rotation angles of the azimuth motor 521 and the altitude angle motor 522 of the helio start control unit 500 are calculated, and the rotation angle is calculated by the azimuth angle motor 521, And the driving angle of the altitude angle motor 522 to calculate the return pulse to drive the azimuth motor 521 and the altitude angle motor 522 to return the Heliostat 400 to its initial state.

Thus, after the sunset, the solar collecting housing 100 and the heliostat are directed to the east direction where the sunrise starts, so that the solar tracking and the heliostart position control can be efficiently performed at the next sunrise without a separate initialization control.

While the present invention has been particularly shown and described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, And it is also within the scope of the present invention to implement the methods proposed by the present invention in software.
