and filling the colored frame of the alternative isolation surface equipment with the second mark.
Specifically, considering that the problem that the identification area is too small and prompt is not obvious when color identification is directly performed on the electrical equipment on the primary wiring diagram is possible, in the embodiment of the invention, a coloring frame can be drawn for the alternative overhaul equipment and the alternative isolation surface equipment in advance, the area of the coloring frame is not smaller than the outline of each equipment on the primary wiring diagram, so that the purpose of enhancing the prompt effect is achieved, and workers can more quickly determine three different types of equipment.
Specifically, the corresponding coloring frame is filled with the color identification, so that the prompt effect can be ensured, and the working efficiency is improved.
The shape of the colored frame may be various, and the embodiment of the present invention is not limited herein.
As a preferred embodiment, drawing a colored frame for the alternative repair equipment and the alternative isolation surface equipment specifically includes:
and drawing a coloring frame for the alternative overhauling equipment and the alternative isolation surface equipment by adopting a point set ordering method.
Specifically, if an algorithm of polygon processing is used, the connecting line to which the given candidate repair device is connected is colored. The basic idea is to calculate all the colored frames of all the alternative repair devices and connecting lines, and then to perform simple point set sequencing according to whether the colored frames are overlapped. Conventionally, the drawn coloring frame only needs to be slightly larger than the size of the outer frame of the device on the primary wiring diagram, but the coloring frame of the specific device and the coloring frame of the connecting line have an overlapping area, and the overlapping point can be removed through calculation of finding the outer frame of the concave polygon. The mainstream using method is that a concave polygon is disassembled into a convex polygon to obtain an outer frame, which includes a large amount of mathematical calculations, if the current system uses distribution network graphics (thousands of devices), the calculation amount is huge, the efficiency is low, and from the perspective of user experience, an interface is jammed or a processing progress bar is popped up.
Therefore, in the embodiment of the present invention, a point set ordering method is used to calculate a rendered frame, and for better describing the embodiment of the present invention, please refer to fig. 2a, fig. 2b, and fig. 2c, where fig. 2a, fig. 2b, and fig. 2c are schematic diagrams illustrating processing effects of the point set ordering method for rendering a rendered frame according to the embodiment of the present invention, and a specific processing flow may be as follows:
1) referring to fig. 2a, the rendered bounding box of the first device is abstracted into four points 1- >2- >3- >4 in order.
2) The colored border of the connecting line is abstracted into four points 9- >10- >11- >12 in sequence.
3) Determining Q, P an intersection of the colored border of the first device and the colored border of the connecting line
4) Adding two points of QP into a coloring frame of the first device, and performing clockwise sequencing: 1- >2- >3- > P- > Q- >4
5) Adding two QP points into a coloring frame of the connecting line, and performing clockwise sequencing: 9- >10- > P- >11- >12- > Q
6) The points contained by the colored frame of the connecting line in the colored frame of the first equipment are removed, and the points contained by the colored frame of the first equipment in the colored frame of the connecting line are removed:
the painted border of the first device does not have to be dotted, and the sequence of the remaining dots is: 1- >2- >3- > P- > Q- >4
9 and 10 points are removed from the coloring frame of the connecting line, and the sequence of the remaining points is as follows: p- >11- >12- > Q
7) Two adjacent points are taken out from the coloring frame of the first device in a clockwise sequence and are respectively marked as a starting point and an end point, and whether the two adjacent points exist in the coloring frame of the connecting line is found out:
if the points exist, taking out a point set between the two points according to the sequence of the corresponding points in the coloring frame of the connecting line, and adding the point set into the set point set E;
if not, the starting point in the colored border of the first device is directly added to the collection point set E.
This step is repeated until there are no unprocessed dots in the colored border of the first device.
Namely 1- >2- >3- > P- > Q- >4 finds that P- > Q points are in P- >11- >12- > Q, and the E point set is 1- >2- >3- > P- >11- >12- > Q- >4 finally, and the treatment effect is shown in figure 2 b.
8) And E: 1- >2- >3- > P- >11- >12- > Q- >4 and 5- >6- >7- >8 are treated by the treatment of the above 3) -7), and the outer frame is 1- >2- >3- > P- > B- >6- >7- >8- >5- > A- > Q- >4, and the treatment effect is shown in figure 2 c.
The point set ordering method can reduce the calculation amount, does not need complex polygon calculation, quickly obtains the result, does not cause interface blockage, and improves the user experience.
As a preferred embodiment, the constraint rule is specifically:
the alternative isolation surface equipment can form at least one topological island and cannot be arranged outside the topological island; the alternative isolation surface equipment consists of a disconnecting knife switch and a grounding knife which is grounded; when the grounding equipment in the alternative isolation surface equipment searches outside the topological island, a disconnected disconnecting link does not exist; the alternative service equipment has no power.
Specifically, the constraint rule provided by the embodiment of the present invention may enable a topology algorithm to accurately determine three types of devices, thereby further ensuring security, and a specific topology calculation process may be:
(1) traversing the equipment of the whole transformer substation, and dividing the equipment into the following classes:
1.1 line (outside the line connection substation, considered as live)
1.2 disconnecting knife switch
1.3 grounded ground knife
1.4 neutral point devices (transformer neutral point devices, usually neutral, which do not participate in the determination of alternative isolation surface devices)
(2) Starting from a line (1.1) of the total station, a group of topological islands is formed in a topological mode without crossing a disconnected disconnecting link (1.2) and without crossing a grounded grounding switch (1.3), and the topological islands are named as an island array A.
(3) Counting equipment without access right:
for a topological island in island array A, if the island does not include a ground knife (1.3) device, then the devices in the island may be non-access devices.
(4) Counting the alternative overhaul equipment:
the equipment of the substation can be divided into two parts of non-access right equipment and alternative access equipment, and the boundary between the non-access right equipment and the alternative access equipment is alternative isolation surface equipment. In the previous step, the equipment without the maintenance right is calculated, and then the statistical method of the alternative maintenance equipment is as follows: and traversing all the equipment of the substation, and if the equipment does not belong to the island array A, or the disconnected disconnecting link, the grounded grounding switch and the neutral point equipment, the equipment belongs to the alternative overhaul equipment.
And if the statistical number of the alternative overhaul equipment is zero, the substation does not have equipment meeting the overhaul condition, or alternative isolation surface equipment, and the calculation is stopped.
(5) And (4) counting the optional isolation surface equipment (disconnecting switches):
the device in 1.2 is traversed and if the device belongs to island array A, then it is an alternate isolation surface device. If the device does not belong to the island array A and is not a 1.4 type neutral point device, the device is an alternative isolation surface device.
(6) And (3) counting alternative isolation surface equipment (grounding earth cutters):
an island in island array A, if the island includes 1.3 devices, then the device is an alternate island surface device.
