Solar Focus Intelligent Tracking System {SMART APPARATUS AND METHOD FOR TRACKING THE SUN}

The present invention relates to a solar-focused intelligent tracking system. More specifically, it is about an intelligent solar tracking method that increases efficiency in the process of tracking sunlight in order to maximize the power production of solar power generation devices.

Solar power generation generally consists of a panel, which is a collection of modules composed of solar cells; a storage battery that stores the generated electricity; As a power conversion device that converts electricity into the required form; It is composed. Solar cells utilize the photovoltaic effect that generates photovoltaic electricity when light is irradiated to the contact surface between a metal and a semiconductor or the pn junction of a semiconductor.

To track sunlight from solar power generation modules, a photo-diode sensor, a type of semiconductor diode, is used. A photodiode is a type of optical sensor that converts light energy into electrical energy, and is a photodetection function added to the PN junction of a semiconductor.

Solar cells and photovoltaic cells have a structure that combines an N (negative) type semiconductor and a P (positive) type semiconductor with different electrical properties, and the boundary between the two semiconductors is called a PN-junction. When sunlight reaches a solar cell, the sunlight is absorbed into the solar cell, and the energy of the absorbed sunlight generates electricity for holes (+) and electrons (-) in the semiconductor. Hole particles and electron particles are generated and each moves freely inside the solar cell, but electrons (-) gather towards the N-type semiconductor and holes (+) towards the P-type semiconductor, thereby generating an electric potential. This causes an electric potential to be generated on the front and back surfaces. When a load is connected to the attached electrode, current flows.

As background technology provided in this regard, installation of a solar power generation module 10a is illustrated in FIG. 1 . In addition, Publication Patent No. 7374 (2012.01.20) and Publication Patent No. 22752 (2013.03.07.) are disclosed.

In solar power generation facilities, it generally takes a lot of time for the solar light to be focused on the photodiode, so the initial access speed of the solar power generation module decreases, and when the weather becomes cloudy, the process of readjusting the solar light focus to adjust it again. There are cases where the efficiency of solar power generation decreases due to the inability to respond quickly.

On the other hand, the photodiode and the condenser lens that forms the solar light focus have limitations in size, so the range in which sunlight can be tracked is narrow, and multiple tracking devices must be used to track sunlight over a wide range. do. Accordingly, an intelligent tracking system focusing on sunlight, such as the present invention, is needed.

It is an intelligent tracking technology that provides a method or means related to solar tracking by tilting the solar power generation module using a concentrator lens, sensor, control unit, and driving unit to accurately form the solar focus on the solar power generation module.

Hereinafter, a detailed description of the present invention will be developed based on the attached drawing examples.

First, we will look at how to use thermocouples and photodiode sensors in the known solar tracking method of background technology. In the solar power generation module, a plate 12 is installed on the lower base 16 through a driving unit, and a plurality of solar power generation elements 14 are embedded in the plate 12. See Figure 2. A solar tracking device 100 is installed in the solar power generation module 10 to always focus the solar rays vertically on the module. By the solar tracking device 100, the solar power generation module 10 always tracks sunlight and generates power by tilting the driving part. At this time, the driving unit controls tilting by the control unit of the solar tracking device, and this is achieved by citing known technology.

The solar tracking device includes a condenser lens 140 that forms a focus of sunlight; It is installed below the condenser lens 140 and is formed in the shape of a horn whose width narrows as it goes downward. A solar light focus is formed by the condenser lens 140 on the inner side, and a plurality of thermocouples 180 are formed along the circumference. ) a detection unit 160 provided; A photodiode 200 provided at the bottom of the sensing unit 160 and divided into a plurality of pieces; And outputting an induction signal to tilt the solar power generation module 10 to the side opposite to the thermocouple with the higher temperature among the thermocouples 180, and when the solar light focus is detected in the photodiode 200, the detected photodiode piece It includes a control unit (not shown) that outputs a precise adjustment signal to tilt the solar power generation module 10 to the opposite side.

The condenser lens 140, the detection unit 160, and the photodiode 200 can be provided with a housing 120 in the solar power module 10 and installed in the housing 120. Specifically, the condenser lens 140 ) is installed in the housing 120 to be horizontal with the solar power module 10, the sensing unit 160 is provided inside the housing 120, and the photodiode 200 is located at the bottom of the sensing unit 160. It is provided to be horizontal with the solar power generation module (10).

The condenser lens 140 is provided in various forms that can form a solar focus, such as a convex lens. As the condenser lens 140 and the photodiode 200 are installed horizontally on the solar power generation module 10, the elevation angle and azimuth are also formed to be the same as those of the solar power generation module 10, and thus the solar power tracking device 100 If the solar light focus exactly matches, it can be seen that the solar light focus of the solar power generation module 10 also matches.

A condenser lens 140 is installed on the top of the housing 120 to transmit incident sunlight and form a solar focus. The formed solar light focus is focused on the inner surface of the sensing unit 160 inside the housing 120, and the thermocouple 180 provided in the sensing unit 160 determines whether the solar light focus is formed and the degree of heat generation of the sensing unit 160. By measuring, it is known where the solar focus is currently formed inside the sensing unit 160. Therefore, through this, it is known where the solar focus is formed in the solar power generation module 10.

By detecting the solar focus of the detection unit 160, it is possible to detect the solar focus in a wider range than when using only a photodiode, and the solar power generation module is controlled according to the location of the solar focus detected by the detection unit 160. By tilting (10), tracking sunlight becomes possible more quickly.

A detection unit 160 may be provided inside the housing 120 below the condenser lens 140 at the top of the housing 120. Such a detection unit 160 is installed below the condenser lens 140 and is formed in a horn shape whose width narrows downward, so that a solar light focus is formed by the condenser lens 140 on the inner side, and along the circumference. A plurality of thermocouples 180 are provided. Specifically, the sensing unit 160 may be in the shape of an upside-down cone, and when the sensing unit 160 is in the shape of a polygonal pyramid, a plurality of sensing panels form the sides of the polygonal pyramid, and a thermocouple (180) is attached to each sensing panel. ) can be provided. The thermocouple 180 provided in each sensing panel can measure the temperature of each sensing panel, and through this, it is possible to determine where the solar light focus is currently formed.

2 and 2 illustrate the case where the sensing unit 160 has a square pyramid shape composed of four sensing panels 162, 164, 166, and 168. When the sensing unit 160 is composed of four sensing panels, each has a direction of north, south, east, west, and through this, it is possible to determine at which point of each point the solar light focus has been formed, and the point where the solar light focus has been formed can be determined. When the solar power generation module 10 is tilted in the opposite direction, the solar tracking device is also tilted and the formed solar light focus becomes closer to the photodiode 200. By installing an insulation member 130 between these sensing panels, heat exchange between the sensing panels can be blocked and the formation location of the solar light focus can be clearly identified through more accurate heat measurement.

Each temperature value measured by the thermocouple 180 in the sensing panel is transmitted to the control unit (not shown). The control unit may be provided at the lower end of the sensing unit 160 in the housing 120, or may be provided at another location of the solar power generation module 10 and connected to enable electrical communication with the sensing unit and the photodiode 200. .

This control unit receives the temperature value detected by the thermocouple 180, determines which thermocouple has the highest temperature among them, and tilts the solar power generation module 10 to the opposite side of the thermocouple. (not shown) outputs an induction signal. The movable part is a component for changing the position or tilting angle of the solar power generation module. For example, it can be divided into a horizontal driving part and a vertical driving part so that the solar power generation module can be tilted in all directions, up, down, left and right. The control unit transmits a tilting signal in a certain direction to the moving part based on the measurement results of the thermocouple, and the moving part tilts the solar power generation module according to the tilting signal, and the solar power tracking device installed on the solar power generation module also tilts. will be.

A photodiode 200 is installed at the bottom of the sensing unit 160 to enable more precise tracking of sunlight. The photodiode 200 is installed at the lower part of the sensing unit 160. As seen above, the sensing unit 160 has the shape of a horn. Part of the vertex of the horn is cut and the photodiode 200 is placed on the cut surface. Be sure to install . The detection unit 160 detects the solar light focus, and the solar power generation module is tilted accordingly. If this process is performed two or three times, the solar light focus is focused on the photodiode 200. The photodiode 200 can measure the intensity of sunlight, and when a certain level of sunlight intensity is input into the control unit as the sunlight focus, it is possible to know whether the sunlight focus is on the photodiode 200. It will happen.

When the photodiode 200 uses a multi-segment photodiode divided into a plurality of pieces, precise control is possible so that the solar light focus is focused on the exact center even inside the photodiode 200 according to the position of the solar light focus. In the case of FIG. 2, the photodiode is a four-segment photodiode divided into four pieces (220, 240, 260, and 280), and the photodiode 200 is formed in a square shape, and the vertex is placed on the tangent line where each of the sensing panels (162, 164, 166, and 168) meet. This photodiode structure, like the detection unit 160, detects the solar light focus in the up, down, left, and right directions and transmits the signal to the control unit, and the control unit receives the signal from each piece of the photodiode to determine the location of the coastal solar light focus. A precision control signal is output to the moving part so that the solar power generation module 10 is tilted in the direction opposite to the solar light focus.

Through this configuration of the detection unit 160, the photodiode 200, and the control unit, the solar power generation module is tilted so that the solar light focus is primarily closer to the photodiode in the detection unit 160, and secondarily, the photodiode 200 By tilting the solar power generation module so that the solar focus is aligned at the center inside, fast and accurate tracking of sunlight is possible with just one tracking device.

Figure 3 shows the solar tracking process,

(a) When the solar light focus (F) is formed to be biased to the left of the upper panel 162 among the sensing panels of the sensing unit 160, the control unit detects Recognize that a solar focus has been formed. The solar focus may be blurred if it is far from the center, but the formation of the solar focus itself will cause a temperature difference in the thermocouple, so at least the location of the solar focus can be determined. When the control unit outputs an induction signal to tilt the solar power generation module in the direction opposite to the solar focus position of the upper panel 162, that is, downward, the solar power generation module is tilted and the solar power focus is moved downward. As the solar focus approaches the center, the size of the solar focus will decrease and its intensity will increase.

(b) As the solar focus (F') moves downward, the control unit determines the moved position of the solar focus through the thermocouple 184 of the left panel 164. In this case, the temperature of the thermocouple 184 of the left panel 164 will be the highest, and accordingly, the control unit transmits a tilting induction signal to the right, which is the opposite direction to the left, to the driving unit of the solar power module. Accordingly, the sunlight focus moves to the right and is focused inside the photodiode.

(c) When the solar light focus (F'') is focused on the photodiode, each piece of the photodiode can measure the intensity of sunlight, so the control unit also determines which piece of the photodiode the current solar light focus is (220, 240, 260, 280). You can find out where it is located. When it is detected that the solar focus is located on the left piece 240, a tilting signal to the right is output. In this case, the signal is a precision adjustment signal at which the solar power generation module operates at a very small angle (for example, 0.1 It transmits a signal to the moving part to tilt in degrees. Through precise control in the photodiode 200, the solar light focus is focused on the central part of the photodiode 200, and from then on, the intensity of sunlight is detected by the photodiode piece at regular intervals or continuously to continuously focus the solar light. It is aligned in the center. Through this process, the solar tracking device continuously tracks sunlight, and the solar power generation module always faces the sunlight directly to maintain maximum power generation efficiency.

When the weather becomes cloudy and then improves again, or when the sunlight is obscured by clouds and then the clouds pass, it becomes necessary to track the sunlight again. In these cases, the sunlight is focused on the sensor, so the sensor detects the signal through measurement. You can quickly align the solar focus on the photodiode 200 and perform precise tracking right away.

FIG. 4 is a flowchart showing a solar tracking method using the solar tracking device shown in FIG. 2. In other words, it is a solar power tracking method that tilts the solar power generation module using a concentrator lens, sensor, control unit, and driver so that the solar light focus is accurately formed on the solar power generation module,

A solar focus induction step (S210) of tilting the solar power module to the opposite side of the solar light focus formed inside the detection unit provided to have a narrow width below the condenser lens so that the solar light focus reaches the lower part of the detection unit; A solar focus detection step (S220) that detects whether the sunlight focus reaches the photodiode 200 provided at the bottom of the detection unit by the solar focus induction step (S210); And when the solar light focus is detected in the solar light focus detection step (S220), a precise tracking step (S230) in which the solar power generation module is tilted to the opposite side of the solar light focus so that the solar light focus is focused on the center of the photodiode 200. ); includes.

In addition, the sunlight tracking method sets the altitude angle and azimuth of sunlight at the current location when the sunlight focus is not detected by the sensor or photodiode 200, and determines the altitude angle and azimuth of the set sunlight and the current sunlight. It may further include an automatic control step (S300) of comparing the altitude angle and azimuth angle toward which the power generation module faces and tilting the solar power generation module to the set altitude angle and azimuth angle if there is an angle difference greater than a set value.

The solar tracking method largely consists of a sensor tracking process (S200) and a program tracking process (automatic control step, S300). The sensor tracking process (S200) tracks the solar focus of the solar power module by directly detecting the solar focus using the physical structure of the sensor, and the program tracking process (S300) directly detects the solar focus using the azimuth and elevation angles. It tracks the solar focus of solar power generation modules without detecting light. Additionally, the solar tracking device of the present invention can be used as the sensor in the sensor tracking process (S200), and the sensor tracking process (S200) and the program tracking process (S300) are used in a complementary manner.

First, the solar focus is detected through a solar tracking device (S100). It detects whether a solar light focus is formed in the detection unit or photodiode 200 of the solar tracking device. If the solar light focus is detected, the sensor tracking process (S200) begins. If the solar light focus is not detected, the Enter the program tracking process (S300).

When the solar focus is detected and the sensor tracking process (S200) begins, the solar focus induction step is executed (S210). In the solar focus induction step (S210), the solar power generation module is tilted to the opposite side of the solar light focus formed inside the detection unit provided to have a narrow width below the condenser lens, thereby guiding the solar power generation module to reach the lower part of the detection unit. do. This is implemented through the detection unit and thermocouple of the solar tracking device described above, and as a result, the sunlight is focused on the photodiode 200 at the bottom.

If the solar focus is detected by the photodiode 200 after 2 to 3 solar focus induction steps, a precise tracking step is performed (S220). In the precision tracking step (S230), the solar power generation module is tilted to the opposite side of the solar light focus using the multi-segment photodiode at the bottom of the detection unit so that the solar light focus reaches the center of the photodiode 200. If the solar light focus is located at the center of the photodiode 200 and the solar light is continuously tracked (for example, in increments of 0.1 degrees), the solar power generation module can accurately view the sunlight and maintain maximum power generation efficiency. It will exist. Meanwhile, there may be cases where the solar light focus is not temporarily formed in the sensing unit or photodiode 200 due to weather changes or sensor failure. In this case, if the solar light focus is not formed for a certain period of time, the program tracking process is initiated so that the solar light can be tracked by azimuth and elevation angle (S250). In the embodiment of Figure 4, if the solar focus is not detected for 5 minutes, the program tracking process is entered. Below, we will look at the program tracking process (S300) in detail.

When detecting the solar light focus through the solar tracking device, if the solar light focus is not detected by the detection unit or the photodiode 200, the program tracking process (automatic control step, S300) is entered. In the program tracking process, the altitude angle and azimuth of sunlight at the current location are set, and the altitude angle and azimuth of the set solar power are compared with the elevation angle and azimuth toward which the solar power generation module is currently facing. If there is an angle difference greater than the set value, the solar power generation module is turned on. An automatic control step (S300) is performed to tilt the power generation module to the set elevation angle and azimuth angle. In the automatic control step (S300), the location information of the modern solar power module is received through the GPS module, and the altitude and azimuth angles of sunlight at the current location are set (S310) using the received location information. In the case of solar azimuth and elevation angles, they can be retrieved by substituting the current time and received GPS geographic information into a pre-prepared data table, or they can be obtained by calculating using a formula.

When the current altitude and azimuth angles of solar power are calculated as above, they are compared with the altitude and azimuth angles currently aimed at by the solar power generation module, and if there is an angle difference greater than the set value, the solar power generation module is tilted to the calculated angle. Do (S320, S330). In the illustrated embodiment, the setting value is set to 0.5 degrees. If the difference in angle is less than 0.5 degrees, it is assumed that the solar focus can be formed in the sensor and photodiode 200 at the currently aimed angle, and the sensor tracking process (S200) is entered into the solar focus induction step (S210). Perform. In this state, if the solar focus is not formed for 5 minutes, the program tracking process begins again (S250). If the difference in angle is more than 0.5 degrees, the solar power module is tilted to the set altitude angle and azimuth angle (S330). If incident sunlight is detected on the sensing unit or photodiode 200 during the tilting process to the set value or after tilting, the tilting is stopped and the sensor tracking process begins (S340).

Meanwhile, in order to protect the solar power generation modules during times when solar power generation cannot be generated, the solar power generation modules should be oriented at azimuth angles of 40 to 50 degrees and elevation angles of 80 to 90 degrees based on 0 degrees true north. The safety step of tilting can be performed (S400, S500). Sunset can be determined by the current time or the heading azimuth and elevation angles. By maintaining the azimuth angle of the safety stage at 40 to 50 degrees, fast tracking of sunlight is possible immediately after sunrise, and by maintaining the elevation angle at 80 to 90 degrees, the solar power generation module is kept parallel to the wind direction overnight, protecting against strong winds. Damage to modules and panels can be prevented.

However, the above-described implementation has the same problem as shown in FIG. 5. That is, the detection unit 160 detects the solar light focus, the solar power generation module is tilted, and the solar light focus is focused on the photodiode 200. As shown in Figure 5 (a), this movement process of the solar light focus (F , F`, F``) are usually passed two or three times, and as the number of times increases, it takes more time to warm the thermocouple 180 of the sensing unit 160 and raise the temperature. In some cases, the path of the movement process may be problematic as it is repeated several times as shown in Figure 5 (b).

In order to solve the above-described problem, the solar tracking method of the present invention is shown in FIGS. 6 and 7,

The solar power generation module is tilted to the opposite side of the solar light focus formed inside the sensing unit 160, which is provided in the form of a square pyramid consisting of four sensing panels with a width narrowing below the condenser lens, and the solar power generation module is tilted to the opposite side of the solar light focus. A solar focus guidance step to reach the edge of the sensing panel,

A solar focus detection step that detects whether the sunlight focus reaches any one of the four photodiodes (201, 202, 203, 204) provided along the length of the edge by the solar focus induction step. and,

When the solar light focus is detected in the solar light focus detection step, the solar power generation module is tilted to the opposite side of the solar light focus, and tilting is performed until the solar light focus reaches the photodiode 203 provided at the edge of the opposite side. Provides an implementation including a tracking step. However, Figure 7 illustrates a case where sunlight is first focused on the photodiode 204 at an adjacent edge.

More specifically, in the side cross-sectional view of FIG. 2 and FIG. 6, the sensing unit 160 takes the shape of a square pyramid consisting of four sensing panels whose width narrows downward, and a photodiode (photodiode) is installed at the longitudinal edge where the sensing panels contact each other. 201, 202, 203, 204) are arranged along the longitudinal direction of the edge in the form of a strip or long plate-shaped bar. Therefore, the photodiodes 201, 202, 203, and 204 are installed in a total of four locations, and are each arranged along the diagonal direction of the sensing unit 160 when viewed from a plan view. At this time, the photodiodes 201, 202, 203, and 204 are installed so that their respective ends are spaced apart from each other, as shown in FIG. 8 (a).

In this way, the band-shaped photodiodes 201, 202, 203, and 204 arranged along the length of the edge of the sensing panel of the sensing unit 160 provide a very fast solar light tracking method, as shown in FIG. 7.

First, in the solar focus induction stage, when the solar light is focused on one of the sensing panels of the sensing unit and the thermocouple (180) (182) of the sensing unit (160) detects the temperature difference, solar power is generated on the side opposite to the solar light focus. A signal to tilt the module is sent to the moving part to operate either the horizontal driving part or the vertical driving part, thereby tilting the solar power generation module to the side opposite to the solar light focus.

Accordingly, when the sunlight focus moves from the first sunlight focus (F1) and reaches the edge of the sensing panel and the second sunlight focus (F2) is formed, it immediately goes to the sunlight focus detection step and the photo installed at the edge It is detected by the diode 201 and goes to the precise tracking stage. At this time, the horizontal driving part and the vertical driving part operate simultaneously and are performed as one quick and continuous operation. In this way, the precise tracking stage can be reached with just one movement from the solar focus guidance stage, providing a very fast response speed, and at the same time, the solar focus position tracking in the wide range described above can be performed.

In the precision tracking step in FIG. 8, the ends of each of the four photodiodes (201, 202, 203, and 204), which take the shape of a band as shown in FIG. 8 (a), are spaced apart and crowded together, and the second solar light focus (F2) is located. is quickly moved and the second solar focus (F2) moves, and when the third solar light focus (F3) is detected by the other photodiode 204, as shown in FIG. 8 (b), the third solar light focus (F3) ) is moved in the direction of the other remaining photodiodes (202, 203) (or the edge end of the other sensing panel), to the center of the spaced ends of the four photodiodes (201, 202, 203, 204) (Figure 8 (c)) As a method of forming a fixed solar light focus (F3'), the solar light focus is located at the center of the sensing unit 160.

In this way, tracking the position of the solar focus over a large area is performed once using the detection panel, and quickly tracking the position of the solar focus once using a strip-shaped photodiode provided along the edge length of the sensing panel. Therefore, it is possible to track the location of solar power in just two attempts. At this time, the precision tracking step performed by the photodiode is viewed as one process.
