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...
Embodiment 2
[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...
