Description

Operation and Maintenance System of Solar Panel Power Plant Through IoT-based Smart Sensor}

The present invention relates to an operation and maintenance system of a solar power generation device through an IoT-based smart sensor, and more particularly, to a device for effectively and actively removing pollution of a solar panel, and various smart devices It is an IoT (Internet Of Things) based artificial intelligence (AI) system (device) that utilizes sensors, and it is a new type of IoT based smart sensor that can improve power generation efficiency. It relates to the operation and maintenance system of the photovoltaic device.

In a photovoltaic system, the power generation efficiency of a photovoltaic panel is affected by the cleanliness of the surface, so the maximum amount of power generation and power generation efficiency are obtained only when the surface of the photovoltaic panel is kept clean. However, dust, yellow sand, algae secretions, rain, and foreign substances left during snowfall accumulate on the panel surface and the process of hardening is continuously repeated, so the surface contamination of the solar panel eventually reduces the power generation efficiency, resulting in economic loss. .

Therefore, in order to continuously maintain the cleanliness of the solar panel, it is necessary to check the contamination and clean the solar panel.

On the other hand, in the case of the brush method, which is partly released on the market, it can cause scratches on the photovoltaic panel by directly contacting the photovoltaic panel to clean it, which may shorten the lifespan of the photovoltaic panel in the mid- to long-term. There is a need for countermeasures.

5 to 12 are views separately showing state diagrams during the cleaning operation of the solar panel and the cleaning module of the photovoltaic device of FIG. 1 .

Referring to FIG. 5 , the solar panel 2 maintains a rectangular shape by left, right, upper, and lower frames 20 , 21 , 22 , 23 in which a plurality of panels 24 form a rectangle. The solar panel 2 is supported by vertical supports 25 and Y-shaped inclined supports 26 and 27 .

A cleaning module 40 is mounted on one side of the solar panel 2 . The cleaning module 40 cleans the surface of the solar panel 2 while continuously moving on the surface of the solar panel 2 in an X-axis and Y-axis movement manner.

The cleaning module 40 is movably installed in the cleaning module guide parts 442 and 444 and is one of the core components of the auto cleaning apparatus.

13 is a flowchart schematically illustrating an auto-cleaning process in an operation and maintenance system of a solar power generation device through an IoT-based smart sensor according to the present invention.

Referring to FIG. 13 , in the auto cleaning process,

A thermal image is acquired from the thermal imaging camera, and an infrared detection signal is received from the infrared temperature sensor (S4).

Then, CCTV and wind speed information is received from the CCTV and the anemometer 9 (S6).

Thereafter, a value is obtained from the RFID tag 49 and matched with the RFID value, and all data received is transmitted to the central control center 50 (S8).

Thereafter, it is determined whether a strong wind occurs (S10). If a strong wind or heavy snow occurs, the inclination of the solar panel 2 is adjusted to prevent damage to the facility (S12). The inclination may be adjusted through the operation of the inclination supports 26 and 27 .

For example, one of the inclined supports 26 and 27 is configured in the form of a hinge in which both ends can be rotated (or it may be configured in the form of a pair of links in which the middle part is folded) and connected to a separate motor device, By controlling the driving of the motor device, if necessary, one of the inclined supports 26 and 27 can be hinged to adjust the reflection direction for the sunlight of the entire solar panel 2 .

On the other hand, if the strong wind does not occur in step S10, it is determined whether there is fallen leaves, snow, rain, or other pollutants by analyzing the image from the CCTV (S14).

Thereafter, an operation command of the cleaning module 40 is transmitted according to the type of contamination source (S18). The operation command signal of the cleaning module 40 according to the occurrence of the strong wind and heavy snow may be transmitted from the central control center server 50 .

After the step S16, the cleaning module 40 performs air spraying (S18), and a soft brush operation or a rubber spatula operation (S18) process is performed. Thereafter, it is determined whether the operation process according to the set operation time or command has been completed (S22), and if completed, the result information is transmitted and reported to the central control center (S24).

14 is a flowchart schematically illustrating an operation and maintenance process in an operation and maintenance system of a solar power generation device through an IoT-based smart sensor according to the present invention.

Referring to FIG. 14 , after step S8 of FIG. 13 , the average data value received for each season, day, and time period is compared with the data value of the target solar panel ( S30 ).

Thereafter, as a result of comparison, it is determined whether the set standard is exceeded (S31).

If the comparison result exceeds the set standard, the result is reported to the central control center 50 (determined as an abnormal panel) (S40).

If, as a result of the comparison, the set criterion is not exceeded, the process of step S30 is continuously performed.

Although some solar panel cleaning devices are released on the market, most products are simple methods in which cleaning is performed only for a predetermined time and a predetermined route according to a preset control value, whereas the auto cleaning device of the present invention has a built-in smart sensor. It is an artificial intelligence (AI) device that analyzes various data information collected through this in real time and is driven by an optimal algorithm through e-learning.

In addition, it is possible to adjust the intensity, movement speed, and frequency of the spraying method according to the weather conditions and pollution sources, and through the periodic self-diagnosis function, the state of the device is maintained in an optimal state and in case of an abnormality, it is promptly sent to the central control center (20). It has a notification function. In addition, it has a system protection function by stopping operation when abnormal weather (lightning, earthquake, strong wind) is detected.

In addition, while performing the cleaning function of the solar panel, the temperature measurement data and thermal image information of each panel through a non-contact infrared thermometer or thermal imager are simultaneously recorded with the RFID tag value attached to the back of the solar panel and the central control center (50) It is possible to analyze the data stored in the database of the central control center in advance to determine whether there is an abnormality in the performance degradation solar panel and to quickly take action by figuring out the exact location of the solar panel. To date, various methods have been proposed to determine the presence or absence of an abnormality in a solar panel, but there was a limitation in the method of accurately identifying the location of a failed solar panel. However, by grafting the IoT technology using RFID proposed in the present invention to a photovoltaic device, it is possible to accurately and quickly identify an abnormal module.

In addition, according to the present invention, it is possible to adjust the inclination of its own when a strong wind or heavy snow occurs based on the results obtained through the smart sensor and data values.

In the present invention, although the detailed operation method for adjusting the inclination of the solar panel is not diagrammed, it is possible to adjust the inclination in 15 degree increments when a certain wind speed (preset value of the administrator) or more or when there is snowfall, a total of 6 steps (0 degree) ~90 degrees) can be adjusted. Although the inclination control function is operated by the data value collected by itself, it allows the control command of the central control center manager to adjust the inclination (tracker function), so that unexpected system malfunction or bad weather can be performed by adjusting the inclination. Facility protection and safety accidents can be prevented in advance. The slope control function has the same control function according to the daily and seasonal insolation for power generation efficiency as well as for facility damage.

As described above, according to the operation and maintenance system of the solar power generation device through the IoT-based smart sensor according to the present invention, in addition to the solar panel cleaning function, temperature and thermal image information for each season, day, and time are stored in the database. When the temperature and deviation from the surrounding panel is large, the power generation efficiency can be maintained at the best state by judging the presence or absence of abnormality through data analysis and operating the photovoltaic power generation system in an optimal state through prompt action if necessary.

As described above, the best embodiment has been disclosed in the drawings and the specification. Although specific terms are used herein, they are only used for the purpose of describing the present invention, and are not used to limit the meaning or the scope of the present invention described in the claims. Therefore, it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible therefrom.
