Referring to fig. 3, an overall architecture diagram is automatically formed based on intelligent zones,

And the distribution Transformer Terminal (TTU) is communicated with each identification module through a broadband carrier wave, generates a platform region topological relation description file (XML) after calculation according to the acquired information, and reports the distribution master station.

(2) User topology description file description
The area wiring diagram takes an area monitoring range as a basic unit, and one area is drawn in a corresponding wiring diagram mode. The topology relation file of the platform region user change takes the platform region allocation as a starting point, takes a user table as an end point and adopts a hierarchical structure for description by using XML. The description information includes: the information such as the area ID, the area name, the equipment ID of each node, the equipment type, the equipment name, the geographic position and the like.

< links > records all connection relationships, each connection contains from and to attributes, pointing to the node ID of the connection, respectively, where from points to the power source side node and to points to the user side node.
(3) User topology data structure design
The main body of the topological relation of the users in the platform area is a Tree structure (Tree), namely, members in the relation are composed of a plurality of homogeneous nodes, each node comprises 0 or 1 father node and 0 or more child nodes, and the sequence among the child nodes does not influence the expression of the topological relation. The data structure of the topological relation of the users in the platform area is designed as follows: connection relations among all the single nodes are described through father nodes and child node (set) pointers of the nodes, and the topology relation tree of the whole platform region user is traversed through different traversing strategies such as 'depth priority' and 'breadth priority'. In combination with the basic equipment attributes, the data structure of a single equipment node in the topological relation tree of the designed area user is shown in figure 5, the data structure of the single equipment node,
the parent node pointer and the child node set pointer point to the memory address of the corresponding node object, the initial values of the node serial number and the node coordinate are null, and the assignment after calculation is needed according to a layout algorithm.
(4) Layout algorithm design
The topological relation wiring diagram of the users in the platform area adopts a horizontal, horizontal and vertical orthogonal drawing method, the nodes on the top layer are positioned at the top of the diagram, the nodes on each layer are unfolded downwards layer by layer according to the hierarchical sequence, the same row spacing is kept between the nodes on each layer, the same column spacing is kept between the nodes of brothers on the same layer, and the father node is positioned at the middle position of all the child nodes. The coordinate position of each node is calculated according to the layout requirement, the coordinate calculation adopts a standard coordinate system, namely the origin of the coordinates is positioned at the center of the drawing area, the X axis is forward to the right, the Y axis is forward to the upward, as shown in the node coordinate schematic diagram of figure 6,
the layout algorithm comprises: two key works of node serial number and node coordinate calculation are arranged.
Node sequence number arrangement
Before calculating the coordinates of the nodes, all the nodes are uniformly numbered, and the main purpose of the node numbering is to find the number of the node related to the current node according to the number of the current node in the process of calculating the coordinates, so that the node object is found, and meanwhile, the node number can reflect certain relations among the nodes. The calculation sequence of the coordinates of the nodes is consistent with the number sequence of the nodes, namely, the coordinates of the nodes with small sequence numbers are calculated first, so that the advantage is that the coordinates of which nodes are calculated at present can be easily known.
According to the hierarchical structure of the tree and the sequence of the peer nodes, a numbering method from top to bottom and from left to right is adopted, as shown in fig. 7, a node numbering schematic diagram,
it can be seen that in this numbering method, the number of the child node is larger than the number of the parent node, and in the same subtree, the number of the left sibling node (minus one) and the number of the right sibling node (plus one) can be conveniently obtained from the current node number, and it is particularly important that, when determining whether two child trees of the same level overlap, only the relationship between the magnitudes of the X coordinates of the rightmost child node of the left subtree and the leftmost child node of the right subtree needs to be determined, for example: in the above diagram, it can be determined whether the 2 and 3 subtrees overlap by determining whether the 5 and 6 nodes overlap or cross. The rightmost child node of the left subtree can be conveniently found from the leftmost child node of the right subtree, and the node numbers have a simple relation of minus one.
The order of node numbering is essentially a "breadth-first" node traversal method employed on a tree structure.
Calculating node coordinates
The calculation of the coordinates of the nodes is carried out according to the numbering sequence of the nodes, a father node and all the direct child nodes are used as reference object units for grouping, and the coordinates of all the child nodes are calculated according to the coordinates of the father node, and the algorithm is as follows: assuming that the coordinates of the root node are (X0, Y0), a layer height value (rowHeight) and a column width value (colWidth) are set, the coordinates of each child node can be conveniently calculated according to a layout algorithm as follows:
because the method only considers the two-layer structure of a father node and a direct child node thereof, when the layer 3 and more than layer 3 are calculated, the problem of node overlapping is inevitably generated, the method for solving the problem of node overlapping is to carry out coordinate translation, and the principle of translation is as follows: the coordinates of the child nodes of the current group are kept unchanged, and the coordinates of the nodes of each group on the left side are shifted leftwards.
Referring to fig. 8, a coordinate translation schematic,
taking fig. 8 as an example, the coordinates of node 1 are defined as (X0, Y0), and the coordinates of node 2 and node 3 in group 1 can be calculated at the time of the first calculation; in the 2 nd calculation, coordinates of the node 4 and the node 5 in the group 2 can be calculated according to the coordinates of the node 2; at the time of the 3 rd calculation, the coordinates of the node 6, the node 7 and the node 8 in the group 3 are calculated according to the coordinates of the node 3. It is apparent that there is an overlap between group 3 and group 2 at this time by shifting all nodes of group 2 to the left so that they do not overlap with group 3 and by shifting the position of node 2 so that node 1 is no longer located directly between node 2 and node 3, the position of node 1 is also adjusted. Meanwhile, as the nodes of group 2 are moved, it is also determined whether group 2 overlaps with the new node to the left, if so, the left translation is continued until there are no more nodes to the left.
The method for judging whether the overlapping exists is as follows: comparing the coordinate positions of the 1 st child node of the current group and the last child node of the last group (such as the positions of the node 6 and the node 5), and the number of the last child node of the last group can be obtained by subtracting one from the number of the first child node of the current group, comparing the Y coordinates of the two nodes, and judging whether the two nodes are on the same level (the same Y coordinate indicates on the same level), if the two nodes are not on the same level, the left translation is not needed.
Calculation of translation distance:
in translation, only the X-coordinate component of the node needs to be changed.
(5) Mapping algorithm design
After the node coordinates are calculated and assigned to the node attributes, the graph can be drawn. The mapping algorithm mainly comprises the following steps: drawing of "nodes" and drawing of "links". According to whether the original image exists or not, the method can be divided into 'full drawing' and 'incremental drawing'. Incremental rendering requires that the node's graphical instance cannot be regenerated, and the rendering of the join line is not limited.
The full-volume rendering is relatively simple, and the incremental rendering is complicated, because in the case of an increment (scene change), the number and position of nodes may change, and the connection relationship may also change.
For unified processing, the full-volume rendering can be regarded as a special case of the delta rendering (i.e., delta rendering with an initial state of null), and the delta rendering algorithm is applied in a unified manner:
for the node, if the node does not exist, drawing a new graphic instance at the calculated coordinate position, if the node exists, finding the graphic instance corresponding to the node, and moving the graphic instance to the new coordinate position; for the connection line, a mode of deleting all the connection lines and then redrawing the connection lines is adopted.
The node is simply drawn, and the connection line is complicated, because the connection diagram adopts a horizontal-vertical orthogonal drawing method, one connection line is divided into a plurality of line segments, and some middle virtual nodes need to be introduced, so that the final effect can be as shown in figure 9,
the blue dots in fig. 9 are segments of an independent connection line between the virtual nodes, between the virtual nodes and the real nodes, or between the real nodes, which need to be introduced.
When the line drawing between the nodes is performed, the line drawing is performed group by group, taking one parent node and all the direct child nodes thereof as reference object units as well, as shown in figure 10,
thus, the drawing algorithm only needs to consider "how the links within the group draw" and "how to traverse all groups".
The internal connection of the group is actually the connection from the father node to each child node in the group, when drawing, virtual nodes are generated and coordinates are calculated according to the number of the child nodes in the group, then the connection is drawn between the (virtual) nodes, and the connection relationship between the (virtual) nodes and the connection is established.
The traversal of the group may be performed in accordance with a "depth-first" traversal method of the tree.
Finally, deleting the equipment nodes (equipment possibly removed) which are in the original wiring diagram but are not in the current user topology description file, thus completing the automatic mapping processing of the user topology of the whole area. The final imaging effect may be as in fig. 11.
