1 shows a schematic configuration diagram of a solar energy system management system according to the present invention.

The solar energy system management system 1000 includes a start check unit 100, an environmental survey unit 200, a control unit 300, a solar sensing unit 400, a communication output unit 600, and a solar energy system unit 500. It consists of.

2 shows the function of the respective components of the solar energy system management system.

The start check unit 100 includes a digital clock and an optical sensor and examines current conditions for driving the solar energy system management system 1000. Current conditions here indicate whether the current time is after sunrise and whether there is enough sunlight to drive the solar energy management system.

The environmental research unit 200 accumulates data detected by the first sensing means including a vibration sensor and a flow rate sensor for detecting an external hazard of the solar energy system device, the vibration sensor, and the flow rate sensor to accumulate the solar energy. It may be composed of a second detection means including a calculation means for calculating the equipment fatigue diagram of the system system, a dirt sensor (rain sensor) and rain sensor (rain sensor) for determining the cleanliness of the solar energy system device At least one of these means or sensors is configured to be provided.

The solar detector 400 is composed of a solar position tracking device, a device for verifying the calculated solar position, and a driving device of the solar energy system device. The solar detector 400 tracks the position of the sun and collects solar energy based on the calculated solar position data. The driving device of the device to be used is operated to check whether the driving device is normally operated.

The controller 300 plays a role of controlling the operation of the solar energy system management system 1000 as a whole. The controller 300 outputs the status of all the components, transmits various commands, and checks whether the normal operation is performed according to the transmitted commands. do.

The communication output unit 600, when the data about the state of all the components of the solar system management system 1000 in the control unit 300 is processed the manager or a central management unit 1100 described later And a control command signal for controlling the solar energy system management system from an administrator or the central management unit 1100.

Let's take a closer look at each of the components of the solar system management system.

3 is a flowchart illustrating an operation of the start checker 100. The operation of the start check unit 100 will be described with reference to FIG. 3.

The operation of the start checker 100 first determines whether an administrator has an input signal from the controller 300 (S101), and if it is determined that the system control signal is input by an administrator, the system is controlled from the outside of the administrator or the central management unit. The system 1000 is controlled by the controller 300 by receiving a signal for controlling the 1000. If it is determined that the administrator control signal is not input, the built-in digital clock determines whether the current time is the sunrise time and whether the sun light exists by the light sensor (S102). If the current time is after the sunrise time and the sun light exists, The controller 300 transmits a weather signal, that is, a signal for driving the solar energy system management system 1000 to 1 (S103).

In addition, if the current time is earlier than the sunrise time or when the sun light is not detected (S102), it is checked whether the built-in digital clock matches the standard time (S104). Is corrected to the standard time (S106), and the process returns to the step of determining the presence or absence of the input signal of the manager (S101). If the built-in digital clock coincides with the standard time, it checks the weather condition and checks whether the current weather condition is within the allowable range, that is, the sun is located on the celestial sphere so that it is possible to efficiently operate the devices of the solar energy system in the current state. Determine (S105). If it is determined that the solar energy system devices can be efficiently operated in the current weather condition, a problem has occurred in the optical sensor for checking whether sunlight exists or not, so that the controller requests a check of the optical sensor (S107). If it is determined that it is impossible to efficiently operate the solar energy system devices in the current weather state, and transmits the weather signal to 0 (S108) to the control unit 300.

4 is a flowchart illustrating the operation of the environmental survey unit 200. The role and operation of the environmental survey unit 200 will be described with reference to FIG. 4.

First, the degree of foreign matter distribution on the outer surface of the solar energy system management system 1000 or the solar energy using apparatus is investigated by the dirt sensor (S201). If the condenser or solar panel that collects light from a device that generates power using solar energy is contaminated by foreign matters, the efficiency of collecting solar heat will be lowered. The dirt sensor is a sensor capable of inspecting the cleanliness of the solar energy using devices without a person checking directly. The dirt sensor is used to determine the cleanness level of the solar energy system management system (S201), and when the pollution level exceeds the allowable value, the self-cleaning device (S207) is operated on the contaminated portion. Further, after the self-cleaning device is operated again, the dirt sensor is used again to investigate the contamination level of the contaminated portion (S208), and if the contamination is not removed, a cleaning request signal is transmitted to the controller 300 to request a cleaning to the manager. (S210), and stops the operation of the solar energy using devices and switches to the safe mode (S211).

In addition, the rain sensor is a sensor for detecting the rain to determine the rain when the rain sensor (S202). Rainy weather over a certain amount is to operate the self-cleaning mode of the solar energy system management system (S207). In this case, the solar panels of the solar energy system are placed vertically in the direction in which the rain drops, and foreign matters accumulated on the solar panels are removed by the falling rain. Furthermore, if it is raining continuously (S209), if the rain is stopped, the environmental investigation unit 200 returns to the beginning of operation of the solar energy system management system 1000, but if it continues to rain, it is no longer used for solar energy. Since there is no need to drive them to stop the operation of the solar energy using devices and switch to the safe mode (S211).

The flow rate sensor detects the degree of wind strength (S203), and when the wind speed exceeds the allowable value, in order to prevent damage to the equipment, the operation of the solar energy using device is stopped and the safety mode is switched (S211).

The vibration sensor checks whether the solar energy system management system vibrates. In the unattended management of solar energy system devices, it is necessary to protect the system by preventing weather conditions or artificial accidents in advance. Therefore, by mounting the vibration sensor to accurately determine the state of the bolt or power transmission device of the solar energy system management system 1000 to prevent the protection and malfunction of the system. When the vibration of the solar energy system management system 1000 is determined by the vibration sensor (S204), if the vibration is more than the allowable value, the operation of the system is stopped and the mode is switched to the safe mode (S211).

Further, the environmental investigation unit 200 calculates the equipment fatigue degree of the solar energy system management system by accumulating the numerical values measured by the flow rate sensor and the vibration sensor (S205). It is determined whether the accumulated equipment fatigue degree exceeds the allowed value (S206), and when the allowed value is exceeded, the operation of the system is stopped and the mode is switched to the safe mode (S211).

When it is switched to the safe mode (S211), the safe mode signal 0 is transmitted to the control unit (S213).

When it is determined that the sensors of the environmental investigation unit operate and the solar energy system management system 1000 can operate normally, the safety mode signal is set to 1 and transmitted to the control unit (S212).

As described above, the environmental research unit 200 examines the operating state and environment of the solar energy system management system 1000 so that the system can operate in an optimal condition, and the administrator can determine whether there is an abnormality of the system even at a remote location. To help.

5 is a flowchart illustrating an operation of the sun detector 400. The operation of the sun detector 400 will be described with reference to FIG. 5.

The meteorological signal inputted by the start checker 100 and the safety mode signal inputted by the environmental research unit 200 are investigated (S401), and the meteorological signal is inputted as 1 (S103), and the safety mode signal is 1 (S212). If input to, the sun detection unit 400 operates the sun position tracking device to track the position of the sun (S402). If the weather signal is input to 0 (S108) or the safety mode signal is input to 0 (S213), the operation of the sun detection unit 400 is immediately terminated because it is not suitable for the operation of the sun detection unit 400.

Here, the sun position tracking device is a device for detecting the position of the sun on the celestial sphere, using a light sensor to calculate the position of the sun or to store data on the pre-calculated sun's movement path and according to the date and time. You can also output the corresponding sun position data.

In order to examine whether the sun position data calculated by the sun position tracking device is suitable, an ultraviolet sensor is used to detect ultraviolet rays at positions corresponding to the sun position data to determine whether or not the reference value is higher than the reference value (S404). The process (S404) is for eliminating the error of the calculated solar position data, for example, when the cloudy day, sunrise or sunset, the solar positioning device is not a celestial sun, but a bright light source such as a street light This is to prevent the error of identifying the position of the sun.

When the ultraviolet rays of the portion corresponding to the solar position data are detected and above the reference value, the driving devices of the solar energy system device are operated based on the calculated solar position data (S205), and if the ultraviolet rays of the position corresponding to the solar position data are If the detected value is less than the reference value, the calculated solar position is determined as the position of the similar light source (S407), and the process returns to the sun position tracking process (S402) again and repeats the above processes and the sun calculated by the sun position tracking process. When the position data is determined as a predetermined number of times or more as a similar light source (S408), the inspection request signal S409 of the sun position tracking device is transmitted.

By operation S405 of the driving devices of the solar energy system device, the solar energy system device, for example, a solar panel or a light collecting plate, is adjusted to the calculated solar position. In this case, it is determined whether the driving devices operate normally based on the calculated solar position data by using an orientation sensor or an inclination sensor (S406). When the driving devices are not normal operation, the driving device check request (S410) signal is transmitted. do.

Furthermore, in order to identify the position of the sun more accurately, the present invention provides a sun position tracking device that captures an image of a celestial sphere where the sun exists and classifies the brightness of the sun to track the position of the sun. Hereinafter, the position tracking device of the sun will be described in more detail with reference to FIGS. 6 to 10.

6 shows an embodiment of a solar position tracking device according to the invention.

The solar position tracking device is composed of an imaging unit 410, an area calculation unit 420, a central processing unit 430 and an output unit 450.

The image capturing unit 410 captures an image of a celestial sphere, and a camera equipped with a lens or a fisheye lens, which can collect a wide range of images, may be used, and each predetermined camera may be set using several cameras. Capturing the celestial sphere allows the entire celestial sphere to be captured at once.

The area calculating unit 420 divides the image of the celestial sphere received from the image capturing unit 410 into a plurality of brightness sections based on the brightness level to distinguish areas and define boundary lines of the areas. A method of dividing an area based on the steps of brightness is described with reference to FIG. 7.

FIG. 7A shows a photograph obtained by dividing the brightness of an image in 256 steps from the brightest part to the darkest part. When the image captured by the digital camera is displayed on a PC, the brightness from the darkest part to the brightest part is 256 steps. Divide by to gradually express the subtle amount of difference. This naturally appears to transition from the darker to the brighter, and in the present invention, the maximum subdivided brightness is set to 256 steps.

(B) of FIG. 7 illustrates the brightness of the image of FIG. 7 (a) by combining the steps of similar brightness with the brightness of 30 steps. Furthermore, FIG. For simplicity, the brightness is expressed in 16 steps. In the celestial image captured by the image capturing unit 410, the central portion of the sun has the highest brightness and the brightness decreases as it moves away from the center of the sun. When the brightness of the image is calculated and the brightness of the image is divided into a plurality of brightness sections based on the brightness level, the brightness sections at similar steps may be represented as one region.

The central processing unit 430 calculates the position of the sun based on the boundary line of each area, which will be described in detail with reference to FIGS. 8 to 10.

Referring to FIG. 8, the process of calculating the position of the sun by the central processing unit 430 will be described schematically. The brightness of the celestial image S431 input by the area calculating unit 420 is calculated and the brightness is calculated. When the image is divided into a plurality of brightness intervals based on the step of S, the image is divided into respective areas (S432).

In operation S433, it is determined whether a circle is formed based on the calculated boundary of the region. When the circle is formed, the step of finding the appropriate brightness to find a step of the appropriate brightness while proceeding from a simple step to a more detailed step to form a circle under the optimal conditions (S434). Here, forming a circle under optimal conditions refers to forming an inscribed circle, an circumscribed circle, a close circle, and the like according to each brightness level to form the most suitable circle.

Thereafter, a circle including a region having the highest brightness among the formed circles is determined (S435).

When the circle is determined (S435), the error range of the determined circle is calculated (S439), and if the error range exceeds the allowable range (S440), the sun position is determined when the error range is within the allowable range. If the error range exceeds the allowable range (S441), the process of capturing the celestial image S431 again and tracking the position of the sun is repeated. Here, the calculation of the error range is to measure the size of the determined circle, and the allowable range is to recognize as the center of the light source when the size of the circle determined in the captured image has a size. Speak about the range. The allowable range may change depending on the state of the captured image, and the change is determined by the accumulated data and the user's setting.

In addition, when a circle is not formed in the process of determining whether a circle is formed based on the calculated boundary of the region (S433), it is determined whether the boundary line of the region and the extension line of the boundary line have a constant direction (S436). .

In the case where the boundary line and the extension line of the boundary line have a constant direction, the optimum condition is found in the most appropriate level of brightness while proceeding from the simple step to the more detailed step, the boundary line of each area and the extension line of each boundary line The range where these intersecting points are formed (S437) is found. Thereafter, a range in which the intersections are formed is determined (S438).

When the range of intersection points is determined (S438), an error range for the determined center is calculated (S439) to determine whether the error range exceeds an allowable range (S440). If the error range is within the allowable range, the sun position is determined (S441). If the error range exceeds the allowable range, the image of the celestial sphere S431 is captured again. Here, the calculation of the error range is to measure the size of the determined range, and the allowable range is to be recognized as the center of the light source when the range determined in the captured image has a certain size. Speak about the range. The allowable range may change depending on the state of the captured image, and the change is determined by the accumulated data and the user's setting.

Hereinafter, the above-described process of calculating the position of the sun by the CPU 430 will be described in more detail with reference to embodiments.

Fig. 9A is an image of a midday sky captured using a general camera. FIG. 9 (b) is a photograph expressing the image of FIG. 9 (a) in eight levels of brightness. Compared to FIG. 9 (a), the size of the brightest area of the center is about twice as large as each other having similar brightness. By processing the steps in the same color, parts other than the original center are recognized as the center area. Accordingly, in the case of the image, when the area is divided based on the brightness step 8 shown in FIG. 9B (S432), a circle is formed based on the boundary line of the area (S433), and the highest brightness circle is calculated (S434). However, when the error range of the calculated circle is calculated (S439) and compared with the allowable range, the size of the calculated circle is so large that the error range exceeds the allowable range. Therefore, in such a case, the process returns to the process of capturing an image of the celestial sphere (S431) and repeats the processes of calculating the sun position. Here, the steps according to the brightness are advanced from simple steps to more detailed steps to find the appropriate level of brightness to form a circle under optimal conditions.

FIG. 9C is a photograph represented by FIG. 9A in 16 steps according to brightness, and FIG. 9D is a photograph expressed in 30 steps. As can be seen from the above picture, the brightness can be further classified to increase the number of steps, thereby reducing the size of the center portion. However, as the brightness level increases, the capacity to be processed increases, so it is necessary to form a circle at the appropriate brightness level. Therefore, the number of steps may be classified into appropriate steps in order to find the optimum condition and reduce the error range, or adjust the number of steps to an appropriate level according to the needs of the user or the condition of the image due to the weather.

FIG. 9E is a photograph showing a boundary portion of each region divided according to the brightness and showing a virtual circle based on the boundary portion. The circle may be implemented as a proximity circle, an inscribed circle, and an circumscribed circle based on the distribution of the same brightness and the like, and may repeatedly implement the shape of each circle and accumulate the processing results to reduce the error. In the case of (e) of FIG. 9, an example is shown in which a circle is formed by gradually finding a circle close to a circle based on the boundary line of each region.

FIG. 9 (f) adjusts the brightness level to an optimum condition based on the accumulated data based on the error of the user or by other factors such as weather, thereby forming a boundary of the region as a complete circle. One picture. Since the circles spread around the light source in the center, the circle with the highest brightness at the center can be predicted as the center of the sun.

10A is an image of a celestial sphere where the sun is hidden behind a cloud and it is difficult to capture its position. Even in this case, it is possible to divide the area based on the brightness level, but it is difficult to form the circle based on the area calculated by the distortion caused by the scattering of light scattered by interference objects or clouds from the solar light source. If you forcibly form a circle that cannot be made, an error occurs in finding the position of the light source in several.

In the present invention, therefore, the center of the sun is found through another process. Since the light has a characteristic of going straight, it can be seen that the light source is located at the intersection point where all the light lines are gathered by tracking back the captured light lines. The present invention uses the linearity of the light to track the position of the sun. Hereinafter, another process of tracking the position of the sun using the straightness of light according to the present invention will be described in detail with reference to FIG. 10.

(B) and (c) of FIG. 10 are photographs showing the image (a) of FIG. 10 in the eight levels of brightness and the sixteen levels of brightness, respectively, and the images of FIGS. By dividing the area on the basis, no suitable circle is formed based on the area.

Therefore, in the present invention, the position of the sun is tracked using another method using the straightness of light in the above case.

10 (b) and (c), it can be seen that a part where the brightness changes abruptly between regions. Here, when the boundary line of the portion where the difference in brightness sharply appears between the regions, it can be seen that the boundary line is a straight line having a constant direction. The boundary line and the extension line of the boundary line can be shown in (d) of FIG. 10, and as shown in (d) of FIG. 10, the boundary line and the extension line of the boundary line have a constant direction (S436) and each boundary line toward a predetermined range. It can be seen that the intersection is formed between the extension line (S437).

 In order to determine the range in which the intersection points are formed, the boundary line and extension line of each region are represented under the optimal conditions based on the implementation of the repeated intersection point and the accumulated error, and the range of the intersection point is determined as shown in (e) of FIG. 10 (S438). )do. Calculate an error range for the range in which the intersection is formed (S439), and if the error range is smaller than a predetermined area (S440), the sun is recognized as being located in the range in which the intersection is formed (S441). Done.

As described above, the solar position tracking device according to the present invention tracks the position of the light source based on the brightness, so that even if there are clouds, abnormal weather phenomena, or physical interference, the position of the sun can be accurately tracked. The operation of solar energy system devices can be maximized.
