Problems solved by technology

However, the current management methods of power optical fiber communication routing resources generally rely on non-automated, paper-based systems to record, track and manage, which is inefficient
In addition, there are few research results on the routing model for power communication network data. When choosing the routing direction of the optical cable, most of them are artificially selected based on the years of work experience and infrastructure planning of the front-line operation and maintenance personnel. This subjective decision is not only low in work efficiency. and there is a high probability of human error
[0003] In the power optical fiber communication network, the communication network path is complex, and the selection of the optimal path of the optical cable routing between two communication plants is a problem that needs to be considered, but this is not a simple shortest path calculation problem that minimizes the length of the optical cable link , but to comprehensively consider factors such as cable length and path attenuation, but often there will be paths with relatively small attenuation, but the cable length is not the shortest. On the contrary, the path with the shortest cable length has not the smallest attenuation. A balance point is removed from it, so the present invention proposes an optimal path selection system for optical cable routing between communication plants and stations based on path attenuation, which can balance the relationship between attenuation and distance in optimal path selection, and achieve full use of network resources. , the purpose of cost reduction

Embodiment 1

[0038] figure 2 A coordinate conversion algorithm flow of a network-wide topology map drawing module provided in the embodiment of this application.

[0039] The whole network topology map drawing module calculates the coordinate positions of the stations in the canvas window according to the latitude and longitude coordinates of the communication stations, and draws each communication station according to the coordinate positions. In reality, communication stations are distributed discretely in various places, so the whole network topology map drawing module needs to map the actual geographical location of communication stations to the canvas window, and the relative position of each communication station in the canvas window should be consistent with The actual geographical relative position is consistent. The optimal path selection system for optical cable routing between communication stations based on path loss uses the existing graphics rendering engine, so the key poi...

[0053] image 3 The flow of an optimal path selection algorithm based on path loss provided by the embodiment of this application.

[0054] The optimal path selection module calculates the attenuation value and distance value of each path from the several available paths obtained in the path analysis module, and performs data normalization processing respectively, and then according to the path attenuation The importance of both the value and the path distance value determines the weight value of the two, and finally according to the weight of the formula, the path with the smallest unified value is the optimal path between the target stations.

[0055] Specific steps are as follows:

[0056] Step 1 is to calculate the distance value of each available path between two target communication stations, and obtain a sequence of distance values.

[0057] Suppose the sequence of distance values ​​(one-dimensional array) is Dis. Assuming that the path analysis module obtains n avai...
