Description

Solar panel management device and system using unmanned aerial vehicle {A SYSTEM AND APPRATUS FOR MANAGING A SOLAR PANEL USING AN UNMANED AERIAL VEHICLE}

The present invention relates to a photovoltaic panel management device and system for maintaining and repairing a photovoltaic panel, and in particular, by detecting an error such as contamination or damage of a photovoltaic panel or a decrease in power generation efficiency by using an unmanned aerial vehicle such as a drone. It relates to a solar panel management system using an unmanned aerial vehicle that supports rapid maintenance and repair.

At present, as the need for various environmental regulations for preservation of the environment, the danger of existing energy generation facilities such as thermal power generation or nuclear power generation, and problems due to the emission of various pollutants have emerged, new and renewable energy is in the spotlight.

Among these new and renewable energy, power generation using solar power, which is inexpensive to build a power generation facility and has high construction convenience, is receiving the most attention, and solar panels are generally used for power generation facilities using such solar power.

In such solar power generation, the power generation performance is determined according to the environmental conditions such as the temperature of the solar panel, snow, dust, etc. on the panel, and the installation location and angle of the solar panel. Is a key factor in determining economic feasibility. The efficiency of solar power generation is up to 22% when the temperature rises, and up to 53% when the top of the panel is polluted.

If enough sunlight is not received for reasons such as shadows or foreign matters among the cells constituting the solar panel, cells that cannot produce power or whose production rate is significantly lower act as a kind of resistance within the solar panel. The resulting electrical energy is consumed due to resistance and converted into thermal energy to appear as a hot spot. The generated thermal energy promotes physical and chemical transformation of the solar power generation system itself, and may cause strings, microcracks, and even fires that diffuse hot spots to surrounding cells.

Therefore, a new means to improve solar power generation efficiency by developing a new detection factor that can check faulty solar panels and easily performing maintenance and repairs for solar power facilities that are difficult to maintain by manpower. And a system is needed.

As the conventional maintenance method for solar panels, there is a method in which the maintenance personnel directly pick up the thermal imager and take pictures one by one.In this case, there is an advantage of being able to accurately see the solar module up close, but it is a lot of time and cost to shoot. It takes. In particular, more manpower and time are required to shoot under conditions of 600KW/㎡ of solar radiation, which is suitable for photovoltaic module photography. In addition, it takes more time for an expert to check the entire module, and it is difficult to check the overall problem in units of strings or arrays.

In addition, in the case of the maintenance method through such maintenance personnel, it is difficult to access the solar panel installed on a building such as a roof and to inspect the floating solar panel, which further increases the cost.

By improving this, in recent years, a technology for observing a solar array by mounting a thermal infrared camera on an Unmaned Aerial Vehicle (UAV) has been developed for efficient monitoring of a solar power plant. The existing developed technology applies a visual analysis method and an output test method that reads an image with the naked eye in order to discriminate a photovoltaic panel whose power generation efficiency is degraded. The visual analysis method is a technology that detects a malfunctioning panel by reading a photographed thermal infrared image with the naked eye, and thus it takes a lot of time to detect a malfunctioning panel and a maintenance cost. In addition, when the power test method is applied, the amount of power generated by each solar panel must be monitored, so there is a limit to practical application.

Meanwhile, in order to detect a malfunctioning panel from a thermal infrared image of a solar panel photographed in aviation, the solar panel region, which is a region of interest (ROI), must first be extracted from a given image. The image of the extracted part must be able to form a polygon divided by panel unit in order to extract a malfunctioning panel through profile analysis for each panel.

In the case of applying the edge extraction techniques developed in the past, such as Canny and Sobel, there arises a problem that it is difficult to manufacture a single polygon for the solar panel due to noise generated inside and outside the solar panel. In addition, when the Hough linear detection technique is applied, an excessive straight line is detected from the thermal infrared image and an artificial condition must be applied according to the image, which is not suitable for use in an algorithm for detecting a panel area.

Patent Document 1 (Korean Registered Patent Publication No. 10-1779040) discloses a method of automatically extracting a panel area from a thermal infrared image of a solar array using computer vision technology without reading a thermal infrared image with the naked eye. .

In addition, Patent Document 2 (Korean Registered Patent Publication No. 10-1967638) discloses the steady state operating temperature of the solar cell panel stored in the control unit of the drone, the ambient temperature at which the solar cell panel is installed, and the steady state temperature data on the temperature at the boundary of the panel. When the temperature measured by the non-contact temperature sensor is judged to be an abnormal temperature by comparing the temperature of the solar cell panel measured by the non-contact temperature sensor of the drone and the drone, the location and measured temperature of the solar cell panel judged as an abnormal temperature by the central control unit The thermal image of the drone is transmitted in order to transmit information and images about the information and the central control unit to capture the thermal distribution image of the solar panel in which the abnormal signal is captured by analyzing the notification signal transmitted from the drone and the image or photo transmitted from the optical sensor. It is possible to operate the sensor or operate the working fluid injection module to remove contaminants from the solar cell panel, clean it, and check the solar cell panel for abnormalities to facilitate maintenance and repair of the solar power generation device. Introducing a solar power module management system using drones.

Patent Document 3 (Republic of Korea Patent Publication No. 10-1943342) allows an unmanned aerial vehicle equipped with a camera to fly over an area where a plurality of solar panels are installed to quickly and quickly determine the actual location of each of the plurality of solar panels installed in the area. Accurately obtainable aerial photography images are acquired, and when an abnormal photovoltaic panel is detected through the image, it supports to easily identify the photovoltaic panel with an abnormality in the aerial image, and at the same time, rapid maintenance can be performed. Introducing a solar panel management system using an unmanned aerial vehicle that guarantees the convenience and efficiency of solar panel management by providing support.

However, since Patent Documents 1 to 3 observe the solar panel while flying the unmanned aerial vehicle from time to time or periodically, it causes excessive flight of the unmanned aerial vehicle, resulting in inefficiency and cost increase. In addition, it causes inefficiency because the drone has to be launched even in weather conditions that are not suitable for the drone to fly, such as snow, rain, typhoon, cloudy, etc., or in weather conditions where it is difficult to acquire images through a camera. Therefore, there is a need for a method to efficiently schedule and manage the flight time of a drone by automatically determining a suitable timing for observing the solar panel in consideration of the environmental and weather conditions of the area where the solar panel is installed.
