Background technique
In photovoltaic power generation application, photovoltaic panel is the root of electric energy production, and the dust in photovoltaic panel can reduce photovoltaic power generation
Photoelectric conversion efficiency.Dust is broadly divided into two classes:
1, floating dust: particle is smaller, is liable to stick in photovoltaic panel, and the process of attachment is a physical process;Floating dust occurrence frequency
Height, but be easier to remove;
2, incrustation: the moisture in air, gluing between photovoltaic panel after dust granule dampness are soaked or absorbed by rainwater
Property become strong, the impurity that can also absorb float is adhered in photovoltaic panel together;Final form becomes point, piece, strip, harder
Firmly;Incrustation probability of happening is low, but is not easy to find in time while being also difficult to remove;
Influence of the dust to photovoltaic power generation is mainly reflected in three aspects:
1, shut out the light: dust can block the light being radiated in photovoltaic panel, and the area that solar radiation is received in photovoltaic panel will
Reduce;And the transmittance of glass can be reduced, to influence photovoltaic efficiency;
2, it hot spot effect: when photovoltaic panel partial region is blocked by dust for a long time, can not work normally;In sunlight prolonged exposure
Under, the heating of covered part can be far longer than not covered part, cause covered portion temperature excessively high and burn out
Blackening, will lead to when serious solar battery large area damage;
3, soda acid corrodes: after the dust deposit with soda acid characteristic is to photovoltaic plate surface, dust will gradually corrode photovoltaic panel table
Face causes possible permanent damage to photovoltaic plate surface, reduces efficiency.
It can be seen that keeping the cleaning of photovoltaic panel is to promote the effective way of generating capacity.Existing clean method includes
It is several below:
1, traditional artificial washing cleaning: inefficiency, high labor cost, cleaning effect are general, water resource waste is serious;
2, photovoltaic panel sweeping robot: also known as on piece robot (as shown in Figure 1);Such as Chinese patent CN103406292A is public
A kind of " photovoltaic module sweeping robot " is opened;The advantages of such robot is that the degree of automation is higher, can effectively remove floating dust,

3, vehicle-mounted mobile cleaning machine: high-efficient, water consumption is small, can effectively remove floating dust and incrustation;The disadvantage is that cannot to incrustation into
The accurate processing of row, energy consumption are higher, need certain manpower and operation management.
In addition, hot spot failure also has a great impact to photovoltaic power generation, the method for detecting hot spot in the prior art includes:
1, traditional artificial detection: inefficiency, time and effort consuming, detection inaccuracy;
2, unmanned plane circling measurment: although efficiency improves a lot, the disadvantage is that at high cost, image data precision is lower, continuation of the journey
Time is short, influences application effect.

S102, starting walking mechanism, are worked in coordination by walking mechanism and suspension guiding mechanism, so that photovoltaic panel sweeping robot exists
Cleaning agency is constantly moved while started in photovoltaic panel, and photovoltaic panel sweeping robot is according to the dirt in front region to be cleaned
Corresponding cleaning modes are arranged in dirt accumulation index parameter;For the different accumulation of mud degree in region to be cleaned, photovoltaic panel is cleaned
Robot has several cleaning modes, includes at least following three kinds:
Rapid cleaning: walking mechanism uses rapid advance speed, and cleaning agency uses weaker cleaning dynamics;
Standard clean: walking mechanism uses normal travel speed, and cleaning agency cleans dynamics using normal;
Strength cleans: walking mechanism uses stronger cleaning dynamics using the speed that proceeds slowly, cleaning agency;
It should be noted that the accumulation of mud degree of each photovoltaic panel is not exactly the same, therefore formulates more be directed in real time
Property cleaning scheme be very important, can not only be promoted clean speed, the dynamics of cleaning can also be controlled rationally to reduce
Cleaning agency is worn caused by photovoltaic panel;
S103, during photovoltaic panel sweeping robot is constantly mobile, by monitoring module captured in real-time photovoltaic panel sweeping machine
The image of the photovoltaic panel in region to be cleaned in front of people direction of travel is analyzed and processed by image processing software/hardware again;When
When the accumulation of mud index parameter in front region to be cleaned changes, cleaning modes are adjusted in time;Meanwhile not by monitoring module
The disconnected shooting photovoltaic panel sweeping robot direction of travel rear image of the photovoltaic panel of purging zone, soft by image procossing again
Part/hardware is analyzed and processed, and is judged effect is cleaned;The rest may be inferred, and photovoltaic panel sweeping robot is in walking mechanism
Under driving, the surface Jing Guo photovoltaic panel to be cleaned and cleaning process is completed one by one;
