In the present embodiment, in the above process, it is according to the method that each photovoltaic module is numbered in location information：
According to the arrangement situation of entire photovoltaic place photovoltaic array and the landforms at scene, place is divided into 01~N number of region,
Each region sets a cleaning equipment.
For cleaning equipment during cleaning for the first time, what upper and lower two groups of range sensors can continue feeds back to range information
Processor, processor can draw curve according to the data that receive, and in curve, abscissa is the time, and ordinate is distance, treats this
After the region that equipment is cleaned, processor analyzes curve, and according to the shape and fluctuation range of curve, interception is different
The curve in section is numbered, and Position Number is carried out respectively to the photovoltaic module array of different location；And it will number according to successively
Sequence is arranged, forming position file.
Wherein it is possible to curve is analyzed using following method：
The region of Y-axis≤200mm in curve is intercepted, in the curve 1 and Figure 14 in two kinds of curves such as Figure 13 being likely to occur
Curve 2 shown in.It, altogether can be by component point according to the variation range of Y-axis by curve 1 and curve 2 as it can be seen that curve is mechanical periodicity
For four regions, A sections are straight line segments, occur primary, all line segment lengths in the section at interval of identical length
Unanimously, which is element panels area, and B sections ramp down first is then straight or first straight, then ramps up, the area
Domain is the rim area of component, and C areas are a cliff areas, the region is between two solar panels among two frame regions
Gap, difference lies in the cliff area head in D areas with C areas in D areas, this is the outside of the outermost component of each array, is cleaned
When equipment is at this, lower section is in vacant state, Gu Douyaqu longer.E areas are also straight line segment, but its y value is than A area
Greatly, this is parking position.The section adjacent with E areas is D areas, but the spacing of curve 1 and the D areas x-axis direction of curve 2 is different, when
During away from more than threshold value, it is believed that scavenging machine is completed to reach parking position after row front and rear at this time, when spacing≤threshold value, it is believed that
After thering is parking position, scavenging machine to clean current array on the outside of current array, parking position is reached.
The photovoltaic module of different location can be then found according to the curve.
After the subregion of A~E is distinguished, the number to each photovoltaic module can be completed in processor, wherein entire curve
First AB section may be defined as the 1st row's component of the 1st array.Behind 1st D area, the AB sections of appearance may be defined as the 1st
1st row's component of array, and so on.Following principle is followed to the number of component, such as：The upper group of first array first row
Part is encoded to (01,0011), and the lower component of first array first row is encoded to (01,0012), first array secondary series
Upper element be encoded to the lower component of (01,0021) first array secondary series and be encoded to (01,0022)..., with such
It pushing away, second array upper element is encoded to (02,0011), and the lower component of second array is encoded to (02,0012),...
Number to parking position is P0X, the number of arrays of the wherein 0X where parking position.
After the number for completing parking position and component, processor can merge all location informations with place General Arrangement,
So as to forming position file.
In subsequent cleaning, cleaning equipment can be marked number component according to the location information in position paper, and
The parameter of the cleaning equipment of marked locations is adjusted.
By the way that component and bit number of parking, forming position file mainly has following effect；
1st, using the position of label " problem " component, subsequently to change the cleaning strategy of this position.
2nd, because photovoltaic place is generally up to thousands of mu of ground, live operation maintenance personnel is found and positioning " problem " component is extremely difficult,
In this way, operation maintenance personnel can be reached behind the region first by searching for the responsible region of cleaning equipment by searching for which
Which component arranged, you can find " problem " component.
For obtained position paper data, due to the variation of outside contamination source factor, the pollution of photovoltaic module on-site
Region is dynamic change, and cleaning equipment according to power plant and cleans motor in use during follow-up use
