[0027] The object of the present invention is to provide a method for identifying areas in a power grid wiring diagram, an electronic device and a readable storage medium, so as to digitize the diagram and realize automatic partitioning.

[0028] Please refer to Figure 1 , Figure 1A schematic flow chart of a method for identifying a region in a power grid wiring diagram provided by an embodiment of the present invention. To achieve the above-mentioned purpose, the present invention provides a method for identifying a region in a power grid wiring diagram, comprising the following steps:

[0029] According to the preset unit length, establish the distance data between each device in the power grid wiring diagram and the preset starting point;

[0030] According to the distance data, starting from the preset starting point, several pathfinding operations are performed, and if a cutoff device or an endpoint device is encountered during each pathfinding process, the pathfinding operation is interrupted;

[0031] After performing the path finding for several times, if there is no newly added truncation device or endpoint device, the preset starting point, the encountered truncation device and the endpoint device are divided into a partition.

[0032] With such a configuration, the present invention can digitally convert the information of any pre-acquired power grid wiring diagram into distance data, so that by using the distance data, it can realize automated batch processing in conjunction with a pathfinding algorithm. Using the pathfinding algorithm to find endpoint devices and truncation devices can help users greatly improve the efficiency of area division and reduce investment in manpower and time costs. It should be understood that the implementation method of the pathfinding includes the use of a pathfinding algorithm. The pathfinding algorithm itself is an algorithm for finding the distance between two points. It can find a path from one point to another and return the path. However, we use the property of the pathfinding algorithm that it can find nodes on the path through digital data. By setting the pathfinding to stop at the endpoint device and the truncation device, and recording each successful path and truncation device, so that the recorded truncation device is the starting point of the next partition, we can finally achieve automatic area division that meets the needs. Figure 2 In the illustrated embodiment, the endpoint devices include transformer A, transformer B, transformer C and transformer D, and the cutoff devices include circuit breaker A and circuit breaker B. The preset unit length can be set in combination with the size of the acquired grid wiring diagram to be processed.

[0033] Furthermore, after the preset starting point, the encountered truncation device and the endpoint device are divided into a partition, the truncation device is used as the new preset starting point, thereby realizing the division and start of other multiple partitions, and finally completing all area identifications.

[0034] Furthermore, if there are partitions that have been divided, when searching for a path from the preset starting point, only the path is searched in the direction of the undivided area. This setting avoids backtracking, records the device information of the partitions, and controls the direction of searching to avoid backtracking and matching the device path. If the found route already contains the device information of the partition, for example, the path direction of circuit breaker A finds transformer A, because this line is backtracked, the path search of this route is stopped and the search for the next route is started. When the area identification of the last partition is completed, all routes have been traversed, and any new path search will cause backtracking. At this time, the area identification of the overall power grid wiring diagram is completed.

[0035] Preferably, the distance data comprises a distance matrix, and the elements of the distance matrix are one of the following data:

[0036] the distance between any two of said devices, where the distance between each device and itself is zero;

[0037] The distance of any device from the preset starting point, where the distance between the preset starting point and itself is zero.

[0038] It should be noted that the distance data between each device and the preset starting point of the power grid wiring diagram is established according to the preset unit length, specifically including:

[0039] If there are several line segments connecting one of the devices and the preset starting point, the accumulated distance of the several line segments is used as the distance data;

[0040] If there is no line segment connection between one of the devices and the preset starting point, the straight-line distance between the device and the preset starting point is used as the distance data.

[0041] Representing the distance data as a distance matrix will enable better coordination with the matrix computing capability of the NPU, further improving work efficiency.

[0042] Combine the following Figures 2 to 4 The embodiments of the present invention illustrate the technical solution:

[0043] Please continue to refer to Figure 2 , Figure 2 A schematic diagram of a power grid wiring diagram provided by an embodiment of the present invention;

[0044] according to Figure 2 , we can get the following distance matrix table:

[0045]

[0046] The outlet switch is the preset starting point, where there is a line connection from the outlet switch to transformer B, and the distance of the line is 5 (2+3). In order to ensure that the wiring diagram is partitioned normally, if the device is not connected to the line, the coordinates are used to calculate the straight-line distance to ensure the accuracy of the partition data. For example, Figure 1 Since there is no line connection between the outgoing line switch and transformer A, the corresponding coordinates are taken as outgoing line switch (0, 0) transformer A (8, -6). The distance from the outgoing line switch to transformer A is 10 according to the coordinate distance calculation formula.

[0047] Please refer to Figure 3 , Figure 3 This is a first partition diagram of a power grid wiring diagram provided by an embodiment of the present invention. Figure 3 As shown, the following three routes are obtained by searching the route from the outgoing switch:

[0048] (1) Outgoing line switch-transformer B (end point device)

[0049] (2) Outlet switch-transformer A (end point device)

[0050] (3) Outgoing line switch - circuit breaker A (cut-off device)

[0051] Thus, the first partition of the power grid wiring diagram is obtained as Figure 3 The dotted box part.

[0052] Please refer to Figure 4 , Figure 4 The second partition diagram of the power grid wiring diagram provided by one embodiment of the present invention. Figure 4 As shown, after the first partition identification is completed, the cut-off device, that is, the circuit breaker A, is used as the new preset starting point, and the path is continued to the unpartitioned direction to obtain the following Figure 4 The second partition is shown in the dashed box.

[0053] Preferably, a greedy algorithm is used for the path finding, which can traverse all endpoint devices and truncation devices of the current partition as much as possible.

[0054] It should be understood that in order to make the data more concise, after performing the pathfinding for several times, if there is no newly added truncation device or endpoint device, the repeated data in the pathfinding process for several times will be deduplicated.

[0055] According to the principle of the path-finding algorithm, if there are multiple sets of distance data between one of the devices and the preset starting point, the distance data with the smallest value is retained, so that the data can be more concise.

[0056] Please refer to Figure 5 , Figure 5FIG. 1 is a block diagram of an electronic device provided by an embodiment of the present invention. Figure 5 As shown, the present invention also provides an electronic device, the electronic device comprising:
