1 to 3, the sensor unit 110 may sense (or sense) an object on the surface of the solar panel 200. In this case, the sensor unit 110 may include at least one of a motion sensor, an image sensor, a heat sensor, and an infrared sensor. As an example, the sensor unit 110 may sense an object based on a shadow captured on the surface of the solar panel 200 using an image sensor (eg, a camera). In this case, the control unit 140 may analyze the information (or the type of the object) of the object based on the shade sensed on the surface of the solar panel 200. As another example, the sensor unit 110 may sense an object based on a motion captured on the surface of the solar panel 200 using a motion sensor.

In this case, the object detected on the surface of the solar panel 200 may include, for example, birds or insects. Therefore, the sensor unit 110 according to the present invention may sense the movement of birds (or insects) located on the surface of the solar panel 200 using a motion sensor.

As an example, as shown in (a) of FIG. 3, when a tide is located in a region on the surface of the solar panel 200, the sensor unit 110 senses the tide using an image sensor (or Can detect).

At this time, the location information of the object includes coordinate information at which the sensed object is located on the solar panel 200. In addition, the location information of the object may include fixed location information of the object, or may include variable location information that is continuously changed according to the movement of the object. In this case, the detection unit 120 for detecting the location information of the object may be omitted. When the detection unit 120 is omitted, the laser irradiation unit designates the area where the object is sensed by the image sensor as a specific area to irradiate the laser.

Meanwhile, the laser irradiation unit 130 may irradiate a laser to a specific area where an object is located on the solar panel 200 based on information on the object detected through the detection unit 120.

In this case, the specific area is an area including an area corresponding to coordinate information in which an object is located on the solar panel 200. As an example, it may be a circular area in which an area corresponding to a coordinate in which an object is located is a center (or reference) and a preset distance is used as a horizontal output radius. Here, the preset distance may be changed according to the user or operator's setting. Also, the preset distance may be set differently according to the type of the sensed object.

Meanwhile, the laser irradiation unit 130 may change a position of a specific area to which the laser is irradiated based on the sensed movement of the object. That is, when the position of the sensed object is changed, the laser irradiation unit 130 may control the laser to be irradiated to a specific area including an area corresponding to the position coordinate information of the changed object.

As an example, when an object on the surface of the solar panel 200 moves from a first position to a second position, the laser irradiation unit 130 includes a first region in which a specific region to which the laser is irradiated includes the first position. In, it may be changed to a second area including the second location. In this case, the first position and the second position refer to different arbitrary regions on the surface of the solar panel 200.

The laser irradiation unit 130 may stop laser irradiation when an object is not sensed on the surface of the solar panel 200.

As an example, as shown in (c) of FIG. 3, when the tide on the surface of the solar panel 200 is removed from the solar panel 200 (or flies) in a state of irradiating a laser, FIG. 3 As shown in (d) of, the laser irradiation unit 130 may stop irradiation of the laser.

Meanwhile, the controller 140 may control overall components constituting the system for managing the solar panel according to the present invention. For example, the operation of the laser irradiation unit 130 may be controlled.

In this case, the laser irradiation unit 130 may irradiate a laser composed of any one pattern among a plurality of patterns generated by the pattern generation unit to a specific region.

Here, a pattern refers to a configuration of dots, lines, planes, colors, or shapes having an orderly arrangement thereof, for example, various types of patterns such as dot patterns, stripe patterns, dotted lines, grid patterns, hexagonal patterns, etc. There is this.

That is, the laser irradiation unit 130 may irradiate a laser composed of any one of a plurality of patterns to a specific region to which the laser is irradiated. However, since it is not necessarily composed of one pattern, the laser irradiation unit 130 may also irradiate a laser composed of a combination of two or more patterns.

Referring to FIG. 4, a method of adding a specific pattern to a region to which a laser is irradiated will be described. First, as an example of a laser pattern, the laser irradiation unit 130 may irradiate a laser composed of a dot pattern on a specific area (see FIG. 4A ).

As another example, the laser irradiation unit 130, the laser irradiation unit 130, may irradiate a laser composed of a stripe pattern or a hexagonal pattern to a specific area (see FIGS. 4(c) and 4(d)) .

Meanwhile, the laser irradiation unit 130 may change a pattern of a laser irradiated to a specific area. That is, the laser irradiation unit 130 may irradiate a laser of a specific pattern to a specific region in which the sensed object is located, and when a predetermined time elapses or every predetermined time, the specific pattern may be converted to another pattern.

As an example, the laser irradiation unit 130 may irradiate a laser composed of a first pattern (eg, a dot pattern) on a specific area where the detected object is located. In addition, when a predetermined time elapses, the laser irradiation unit 130 may convert the laser of the first pattern into a laser of a second pattern (eg, a stripe pattern) different from the first pattern. In this case, the laser irradiation unit 130 may control to set the pattern of the laser irradiated at the time the object is removed from the solar panel 200 as a basic laser pattern.

As described above, by adding a pattern to the irradiated laser and changing the pattern at preset time intervals, an object located on the solar panel 200 can be more efficiently removed.
