Technical Field

[0001] The present invention relates to the technical field of power communication optimization, and in particular to a digital power communication optical transmission network optimization system and method. Background Art

[0002] In recent years, with the continuous development of the power system, the power communication network, as one of the important pillars of the power grid, has also accelerated its construction. The power communication network is the basis for dispatching automation, marketization of network operation and modernization of management. It is an important means to ensure the safe, stable and economic operation of the power grid. It is also an important infrastructure of the power system. Improving the operation level of the power communication network is of great significance to the safety and stability of the power grid.

[0003] Optimizing the optical transmission network can significantly improve the transmission efficiency of the power communication system, reduce data transmission delays, and improve the overall stability and response speed of the network. This is of great significance for power dispatching and grid management, and can better meet the needs of modern power systems for efficient and stable communications. By optimizing the design and configuration of the optical transmission network, the maintenance cost and operational risks of the equipment can be reduced. The optimization plan can reduce the problems caused by equipment aging, extend the service life of the equipment, and reduce the maintenance and replacement costs caused by equipment failures.

[0004] However, traditional communication optical transmission network optimization has the following disadvantages:

[0005] In the actual practice of traditional communication optical transmission network optimization, the optical transmission network not only has many nodes but also has a relatively simple structure, which seriously affects the security and reliability of the network. The traditional optimization method cannot meet people's usage needs. Summary of the invention

[0006] The purpose of the present invention is to provide a digital power communication optical transmission network optimization system and method to solve the problem that in the specific practice of the traditional communication optical transmission network optimization proposed in the above background technology, the optical transmission network not only has many nodes but also has a relatively simple structure, which seriously affects the security and reliability of the network, and the traditional optimization method cannot meet people's usage needs.

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a digital power communication optical transmission network optimization system, including a network optimization system, wherein the network optimization system includes an optimization strategy platform, a main body optimization platform, a transmission planning platform, a topology optimization platform, a security protection platform and an application optimization platform.

[0008] As a preferred technical solution of the present invention, the optimization strategy platform includes an online acquisition module, a technology fusion module, a transmission optimization module and a wireless communication optimization module;

[0009] The online collection module collects different communication information separately in a hop-by-hop collection mode in the communication network, or in an explicit collection mode. Combining the advantages of the two, it is necessary to build parallel or series collection lines to ensure that the collected information remains interrelated, avoid network congested lines, and ensure that from the overall perspective of the radio and television network, the network traffic is accurately controlled. On the basis of obtaining information, the communication congested sections are marked according to the collected information. The technology fusion module optimizes the communication network using the unique advantages of SDH optical transmission technology, and integrates it with SDH optical transmission technology to design a complete new communication network. Based on SDH optical transmission technology, reasonable changes are made to the network lines to ensure that the communication network terminals and external devices are better connected together, and that the component functions are reasonably interchangeable. Ensure that the singleness of the previous communication network terminals is changed and the intelligent goals are continuously achieved. The transmission optimization module focuses on controlling network resources, so that the communication sending and receiving ends cooperate with each other, accurately predict the security risks in the communication network, and enhance the fluency of the core performance of the communication network. The wireless communication optimization module connects the TD-LTE wireless communication network to ensure smooth wireless communication.

[0010] As a preferred technical solution of the present invention, the main body optimization platform includes a backbone node optimization module, an access layer optimization module, a circuit layer optimization module, a channel layer optimization module and a transmission medium layer optimization module;

[0011] The backbone node optimization module converges the routing and bandwidth of the backbone layer to form a ring or mesh network, selects different optical cable routing networks and direct circuits in different SDH ring network systems with self-healing protection, reduces jumper switching, load shares the access layer services, dual-homes the access ring, and reasonably increases the number of backbone nodes and backbone rings. The access layer optimization module uses optical fiber resources to split the access ring according to the actual situation of the access ring whose capacity has been saturated, that is, to split the access into two, thereby increasing the capacity of the network, and setting the number of access points carried by the access loop within the range of 8. For loops with relatively many nodes, the ring dismantling method is used to increase the capacity of the loop. According to the growing business needs, the capacity of the ring network is increased through upgrading. The circuit layer optimization module is directly connected to the ports of the transmission equipment through the circuit. The circuit optimization is actually the optimization of the ports of the network element equipment at both ends. The channel layer optimization module optimizes the high and low order channels on the network management and optimizes the protection channel using the subnet connection protection method. The transmission medium layer optimization module adjusts the manufacturer's independent optical transmission equipment to the regional or branch network, and optimizes the backbone network into a ring network through the branch network. Then, according to the increase in network elements, the network is adjusted to an independent 2-layer network.

[0015] The minimum spanning tree algorithm submodule is used for a weighted connected undirected graph G = (V, E). The spanning trees are different, and the weight of each tree, that is, the sum of the weights of all the edges in the tree, is also different. Let R be the set of all spanning trees of G. If T is the spanning tree with the smallest sum of the weights of the edges in R, then T is called the minimum spanning tree of G. The Kruskai algorithm submodule is used for any connected graph N = {V, E} with n vertices. First, a graph G = {V, NULL} consisting of these n vertices and without any edges is constructed, in which each vertex is a connected component. Set, then continuously take out the edge with the smallest weight from E. If there are multiple edges with equal weights, select any one of them. If the two vertices of the edge come from different connected components, add this edge to G; repeat this process until all vertices are on the same connected component. In each iteration, select an edge with the smallest weight, and the two endpoints of the edge are not on the same connected component set, and add it to the spanning tree. The points array in the Prim algorithm submodule is a two-dimensional array, and each row represents the coordinates of a point. The weight calculation formula of the edge between two points is:

[0016] |xi-xj|+|yi-yj|,

[0017] It is required to connect all points and minimize the weight of the entire graph. Consider using the prim algorithm. Initially, it is assumed that there is an edge directly connecting any two points in the graph. Use the adjacency matrix g to store the graph, g[i][j] represents the weight from point i to point j, and then use the prim algorithm to get the minimum spanning tree. In the process of getting the minimum spanning tree, use a variable rst, which is initially assigned to 0. Whenever a point is added to the minimum spanning tree, rst accumulates the weight of the corresponding edge and finally returns rst.

[0018] As a preferred technical solution of the present invention, the security protection platform includes an encryption module, an access control module, a security audit module and a firewall module;

[0019] The encryption module uses encryption technology to encrypt data transmitted in the fiber-optic communication network to ensure that the data will not be stolen or tampered with during transmission.

The security audit module conducts security audits regularly to detect and analyze security incidents, vulnerabilities and abnormal behaviors in the fiber-optic communication network to promptly discover and resolve potential security issues.
