Embodiment Construction

[0021] The basic idea of ​​the present invention is to provide a satellite cable shortest path planning method based on directed graph optimization technology. For the satellite cable path design problem, the method uses the spatial position of each cable binding node in the satellite layout, and any two cable binding nodes. The connectivity relationship of the nodes is used as input to form an initial directed graph of the cable path. Using the directed graph shortest path algorithm, the cable shortest path distance matrix and the shortest path node sequence between any two cable binding nodes are calculated. This method has completed the shortest path design of the satellite cable and the calculation of the cable length under the shortest path, and can meet the cable direction planning optimization requirements in the design of the satellite cable. The shortest path solution method in the method of the present invention, the cable path obtained is theoretically guaranteed to b...

Abstract

The invention discloses a satellite cable shortest path planning method based on the digraph optimization technology. The method employs the spatial position of each cable binding node in satellite layout and the connection relation between any two cable binding nodes as the input, thereby forming a cable path initial digraph. The method calculates a cable shortest path distance matrix and a shortest path node array between any two cable binding nodes through a digraph shortest path algorithm. The method comprises the design of a satellite cable shortest path and the calculation of a cable at the shortest path, and can meet the demands of cable direction path planning in the satellite cable design. A cable path obtained through the method is guaranteed to be the optimal path in theory. Compared with a conventional method which employs a 1:1 satellite platform wood model or employs manual operation to carry out actual cable length sampling according to a cable design path two-dimensional drawing, the method reduces the design time, and guarantees the design quality.
