The present invention relates to a device capable of more accurately detecting the amount of sunshine and a method of enabling the display of more accurate sunshine time using the device.

In general, the sunshine volume refers to the amount of sunshine (light) reflected on the ground without being obscured or reflected by clouds, fog, and dust floating in the atmosphere. The unit is usually expressed as an hour (hr). . Since the amount of sunshine is closely related to human life such as plants, grains, and homes, the technique of measuring the average amount of sunshine is also very important.

Or outputting a control signal for driving the driving means to rotate to the right, and detecting the amount of sunshine using the main sensor signal value when the difference between the average values of the first and second auxiliary sensors is within an allowable error range. It is characterized in that it comprises a controller for calculating this in sunshine time.

That is, the lower case 17 may be configured to automatically adjust the angle through a separate drive means for receiving the control signal of the controller 11, so that the rotation direction can also be rotated back and forth and left and right directions Of course, it can be configured.

In addition, the inner cover 19, the outer cover 21 and the case cover 25 of the housing means are all made of a material that accepts as it is without reducing and increasing or reflecting sunlight, as a rule, In some cases it may be made transparent.

On the other hand, after receiving the signals of the main sensor 3 and the first and second auxiliary sensors 7 and 9, the driving means according to whether the average value of each of the first and second auxiliary sensors is matched, that is, whether or not to enter the tolerance range. An axial rotation is made to the left or right of the rotary column 1 through 13 and when the average value of each of the first and second auxiliary sensors is identical, the amount of sunshine is detected and detected using the signal value of the main sensor 3. The configuration of the controller 11 for calculating the sunshine time by using the amount of sunshine is described with reference to FIG. 4.

In addition, the sunshine detection device according to the present invention is a means for supplying power (not shown), and a display means for displaying a data value obtained by converting the amount of sunshine detected by the controller 11 to time (sunshine time) 14 ) Is further included.

On the other hand, using the signals of the main sensor (3) and the first and second auxiliary sensors (7, 9), the data detected by the amount of sunshine and the amount of sunshine detected in the controller 11 as time (hr) is as described above The display 14 may be displayed to the user, but may be received and used by the Meteorological Administration, which requires the sunshine time data displayed through the display 14. To this end, it will be possible for a person skilled in the art to provide a sunshine time data transmission in real time under the control of a controller after the wired / wireless communication means is provided on the sunshine detection device according to the present invention.

It is implemented in an automated way.

A sunshine detection method according to the present invention will be described with reference to FIG. 4 with reference to FIG.

As shown in FIG. 5, first, the main sensor 3 and the first and second auxiliary sensors 7 and 9 are received through the signal input unit of the controller 11 [S10].

In addition, after summing the signal values of the first auxiliary sensor 7 and the signal signal of the second auxiliary sensor 9 received in step S10, the average value is calculated [S20], and the calculated value of the first auxiliary sensor 7 is calculated. It is determined whether the difference between the average value and the average value of the second auxiliary sensor 9 is within an allowable error range [S30]. In the above, the allowable error range when comparing the average value of the first and second auxiliary sensors may be set to an optimum value through experiments.

As a result of the comparison in the step S30, when the difference between the average value of the first auxiliary sensor 7 and the average value of the second auxiliary sensor 9 is outside the tolerance range, the direction in which the current sunlight shines is the first auxiliary sensor 7 or In order to compensate for this, in the present invention, the first auxiliary sensor 7 or the second auxiliary sensor 9 has a mean value larger than that of the second auxiliary sensor 9 in the direction of the sensor. Accordingly, the driving column 13 is rotated to the left or right by the rotation of the main sensor and the first and second auxiliary sensors so that the difference between each average value of the first and second auxiliary sensors can enter the tolerance range. It is [S40].

On the other hand, when the comparison result in step S30, the difference between the average value of each of the first and second auxiliary sensors (7, 9) is within the tolerance range, the position of the current main sensor (3) is located almost in line with the direction of sunlight It is determined that the main sensor signal value at this time is stored [S50].

In the step S50, after detecting the amount of sunshine using the stored main sensor signal value in the state that the difference between each average value of the first and second auxiliary sensor is within the tolerance range [S60]. Sunlight calculation method according to the invention is shown in the graph of FIG.

As shown in FIG. 6, in the present invention, in detecting the amount of sunshine, that is, the sunshine time, hr, only the amount of light above the set reference value after setting the reference value of the amount of light detected by the main sensor, unlike the conventional sunshine detection method It detected by (A), and the time when the light quantity more than a reference value is detected is calculated as sunshine time. As a result, more accurate sunshine and sunshine time detection can be achieved regardless of season and weather. For reference, the reference value setting of the main sensor value in the above it would be desirable to set the optimum value through the experiment.

Returning to the flowchart of FIG. 5 again, after calculating the amount of sunshine (sunlight time) in step S60, it is determined whether the amount of sunshine detection is completed [S70]. If the sunshine amount is not completed, the process returns to the step S10, but the sunshine amount is completed. In this case, the calculated sunshine time is displayed on the display means 14 [S80]. In addition, the sunshine time data displayed through the display means may be provided in real time to the meteorological office that requires the data through wired / wireless communication means as described above.

As described above, according to the present invention, it is possible to display the sunshine time while accurately detecting the amount of sunshine regardless of the season and the weather, and the device can be driven in an unmanned and automated manner under the control of the controller of the sunshine detection device. In addition, it has an effect that can be provided through wired / wireless communication means such as a meteorological agency requiring the calculated sunshine time data.
