Furthermore, path planning is performed on the final network topology to obtain the optimal transmission path, thereby shortening power transmission delay and improving the overall efficiency of power transmission.
[0073] Specifically, the target area can be the power supply area of a substation, etc.; the transmission equipment is used for power transmission information, mainly including modulators, demodulators, etc.
[0074] In one implementation, the noise figure value calculated for the target node in the target network topology graph includes:

[0077] in, Represents the noise value of the target node, for The noise figure value is obtained by normalization and denoted as L; m represents the number of connections between the target node and its neighboring nodes, M represents the upper limit threshold of the number of connections between the target node and its neighboring nodes; p0 represents the standard frequency band of the target node, n represents the total number of characteristic frequency bands generated by the target node, pi represents the i-th characteristic frequency band generated by the target node, and e represents the natural constant.
[0078] In one implementation, the characteristic frequency band is a key frequency information segment selected from a complex signal; the characteristic frequency band mainly comes from the characteristic frequencies of various electromagnetic signals and vibration signals generated during the operation of the transmission equipment.
[0079] In one implementation, the final network topology is reconstructed based on the set of noisy nodes and a preset noise threshold, including:
[0080] Obtain the noise coefficient values of each noise node in the noise node set, and compare each noise coefficient value with the preset noise threshold to determine whether to remove the target node;

[0083] If the noise coefficient value is less than the preset noise threshold, the target node is retained;
[0084] If the noise coefficient value is greater than or equal to the preset noise threshold, the target node is eliminated.
[0085] In an implementation manner, referring to Figure 2 , Figure 2 A flowchart of path planning provided by an embodiment of the application includes path planning of the final network topology graph to obtain an optimal transmission path.
[0086] According to the final network topology graph, a starting point and an ending point are determined, and all intermediate nodes between the starting point and the ending point are obtained;
[0087] The final network topology graph is divided into various clustering clusters using a K-means algorithm;
[0088] A target path optimization is performed on a target clustering cluster to obtain a locally optimal transmission path; the target clustering cluster is any one of the various clustering clusters;
[0089] The locally optimal transmission paths corresponding to the various clustering clusters are obtained, and a locally optimal transmission path set is determined;
[0090] The locally optimal transmission path set is sorted in ascending order of the fitness values of the target locally optimal transmission paths to obtain an optimal transmission path; the target locally optimal transmission path is any one of the locally optimal transmission paths.
[0091] In an implementation manner, the K-means algorithm is used to divide the clustering clusters of the final network topology graph, which can reasonably group the complex power data transmission network and classify the nodes with similar transmission characteristics into one category, thereby reducing the complexity of subsequent path optimization. The target path optimization is performed on each clustering cluster to obtain a locally optimal transmission path, which finely improves the path transmission efficiency in a local range, so that the power data transmission in each clustering cluster can reach a good state.
[0092] In an implementation manner, dividing the final network topology graph using the K-means algorithm to obtain various clustering clusters includes:
[0093] S1: Extracting all intermediate nodes in the final network topology graph, performing a K-means algorithm on all intermediate nodes to obtain various initial clustering clusters, and calculating the number of intermediate nodes of each initial clustering cluster;

[0095] S3: repeating step S2 until the intermediate nodes of each initial clustering cluster reach the preset average number of nodes, and outputting each clustering cluster.
[0096] In an implementation manner, the target path optimization on the target clustering cluster obtains a local optimal transmission path, and the local optimal transmission path comprises:
[0097] The target clustering cluster is initialized as a population, each fitness is obtained by calculating the population through a fitness formula, and the optimal chromosome corresponding to the highest fitness is taken as an evolution target to be iterated through quantum evolution operation; the population comprises a plurality of chromosomes;
[0098] If the quantum genetic algorithm meets a convergence error or reaches a maximum number of iterations, a local optimal transmission path is outputted;
[0099] The fitness formula is specifically:
[0100] ;
[0101] Wherein, γ represents the fitness, represents a wireless channel delay of a connection edge between the jth node and a previous node in the target clustering cluster; represents a wired channel delay of a connection edge between the jth node and a previous node in the chromosome; j = 1, 2, …, J; J represents a total number of nodes in the target clustering cluster, and Ys represents a preset noise threshold; represents a noise coefficient value of the jth node in the target clustering cluster.
[0102] In an implementation manner, the target clustering cluster is initialized as a population, and iteration is performed in combination with a fitness formula and quantum evolution operation, so that the clustering cluster obtains an optimal transmission path. The quantum genetic algorithm outputs a local optimal path according to a convergence error or a maximum number of iterations, thereby guaranteeing the efficiency of optimization and the rationality of termination. The convergence error or the maximum number of iterations is set by a staff member according to historical experience; the fitness formula comprehensively considers the transmission time and power constraints between nodes, so that the optimized path not only pursues high transmission efficiency, but also meets system resource constraints. The local optimal transmission path can be accurately obtained in the target clustering cluster, which lays a foundation for subsequent integration of local optimal paths of each clustering cluster and acquisition of an overall optimal transmission path, thereby improving the efficiency and stability of power data transmission in the entire network topology, enabling terminal equipment to more reliably and quickly receive power data, and providing strong support for efficient operation of a power system.
