Detailed description of the invention
Below with reference to the accompanying drawings the preferred embodiments of the present invention are described.
Embodiment one
The structure chart of a kind of information system realizing mesh lean management that the present invention provides is as shown in Figure 1.Specifically include: mesh definition module, Mesh Fusion module, gridding device statistics analyze module, gridding line loss analyzing module, gridding rolls meter-reading module, gridding tariff recovery rate analyzes module and gridding power failure analog module.
Mesh definition module, the basis of grid-based management is the definition of grid, and this module is for drawing the shape of grid, it is intended that management ownership place, defines the outward appearances such as grid title, grid mark, coloring and controls.
Mesh Fusion module, for being fused into bigger administrative unit according to the superior and the subordinate of administrative unit belonging to grid, it is achieved the statistical analysis of higher level.Mesh Fusion module uses polygon aggregation algorithms to carry out Mesh Fusion.
Polygon aggregation algorithms is for merging multiple legal polygon, and legal polygon is satisfied: (1) adjacent segments only connects at a common ground；(2) polygon that non-adjacent line segment does not connects at any common ground.
Algorithm includes following key step: (1) generates respectively with directive polygon loop and the list of ring；(2) loop is merged；(3) disposal hole；(4) hole is inserted in the loop after merging.Generate with directive polygon loop and the list of ring the most respectively, merge loop the most again and merge polygon.Merging loop first head and determining common limit and summit, used here as the method for scan line, divide the plane into the belt-like zone of a rule, task required in band can rapidly complete.Scan line is inswept plane from minus infinity to positive infinity, only stops in the position having task, carries out calculating or more new data structure.When searching for polygonal joining, it is contemplated that and is just scanned the polygonal limit that line skims over.Only these limits are possible intersection edges, and they are stored in data structure group sweep-linestatus, are referred to as this scan line state array (SLS).For the carrying out making scanning smooth, be sorted by the direction of motion of scan line in summit.
As a example by Fig. 2, explanation merges polygon.
From 0001Starting, because not sharing with other any polygon, pointer T is NIL altogether.Walking is to next polygonal limit 0102, its pointer TpointerIt is NIL, so limit 0001Can accept.Equally, limit 0203Also accepted.But next limit 0304Pointer T be not NIL, it points to polygon P11Limit 111112, therefore, this algorithm skips this edge, and along polygon P11Limit walk on, limit 112110It is accepted as connecting next limit polygonal.Equally, limit 110111Accepted.Next limit 111112Point to limit 0304, this is intended to change polygonal signal, along 0304Walking, arrives limit 0405, walking is to limit 0 further14015, its pointer T points to limit 3033.Algorithm skips this limit, walking to adjacent 3031, its pointer T is non-NIL.Next polygon P is jumped to from this edge5Limit 5152, limit 5052Pointer T is NIL, therefore accepts this limit.Algorithm has had returned to initial line 0 now001.So the limit of that not all band NIL pointer T is all accessed, so same walking is further continued to be carried out, finds again 2 loops: one by limit 0809, 4142, 6162And 0708Composition, another is by polygon P12And P13Limit constitute.Finally, the polygonal closure having been found that is checked.
Gridding device statistics analyzes module, and for the shape according to mesh definition and position, the device data in conjunction with generalized information system carries out device statistics analysis and generates grid special topic view.
Gridding device statistics is analyzed module and is carried out device location and the spatial analysis of gridding regional extent.Most equipment is classified as the analysis of point device, i.e. with the analysis of polygonal spatial relationship, have employed " light cone QCD sum rule " algorithm idea.This algorithm only needs the additional space of O (1), and time complexity is O (n), but coefficient is the least.Maximum advantage is to have the highest precision, only need to do multiplication and subtraction, if for rounded coordinate, entirely without precision problem, and implements very simple, is better than angle method and ray method and the most error-prone.The polygon in gridding region is an oriented polygon, and definition is along polygonal forward, and the left side on limit is territory, polygonal inner side.With measured point for center of circle office circle, whole directed edges are made radially projecting to unit circle, and calculate the algebraical sum of arc length on wherein unit circle.If algebraical sum is 0, then put at outside of polygon；If algebraical sum is 2 π, put at polygonal internal；If algebraical sum is π, then put on polygon.
Zero moves to measured point P, and plane is divided into 4 quadrants by this new coordinate system, to each polygon vertex P, only consider the quadrant at its place, then by adjacent sequential access each summit polygonal P, analyze P and P [i+1], have a following three situation:
(1) P [i+1] is at next quadrant of P.Now arc length and add pi/2；
(2) P [i+1] is at a upper quadrant of P.Now arc length and subtract pi/2；
(3) P [i+1] is at the relative sector of P.First f=y [i+1] * x-x [i+1] * y(cross product is calculated), if f=0, then put on polygon；If f ＜ 0, arc length and subtract π；If f ＞ 0, arc length and add π.
If certain coordinate of P is 0, process when positive sign without exception；If second point is to want special handling when measured point and the coincidence of polygonal summit.When polygonal certain limit is on coordinate axes and during both sides at initial point respectively, two summits: when calculating P and P [i+1], just calculate cross product and dot product, it is judged that this point, whether on this limit, is, judge to terminate, otherwise proceed as described above every time.So sacrifice the time, but ensure that correctness.
