Problems solved by technology

In the search for the shortest cable path, some algorithms are slow to calculate the cable path in a complex channel network, and the efficiency is not high, such as Dijikstra algorithm, Floyd algorithm, etc.; when the 3D digital model of the channel generates the channel topology network, there are various types of channels on the project site. And there is a situation that the channels are disconnected but connected during actual installation; in addition, some software does not consider the channel volume ratio limit, but only plans the cable path, resulting in the failure of laying cables in actual engineering

Embodiment 1

[0063] This embodiment is a workflow of an embodiment of a method for planning an optimal cable path. Figure 2a Shown is a flow chart of the steps of the path planning method in the embodiment of the present invention, including the following steps:

[0064] Step S1: Set the short-distance threshold s, and create initial data information, including creating an initial channel set and a connection point set and setting them empty. The channel set is a collection of channels, and the connection point set is a collection of connection points.

[0065] Step S2: traverse the channel models in the 3D digital model, and construct the connection relationship between the channel models that are directly connected or closely connected.

[0066] Traverse the channel models in the 3D digital model, take the next channel model to be calculated as the current channel, search whether there are other channel models within the range of the threshold s with the coordinates at both ends of the...

Embodiment 2

[0103] This embodiment is a workflow of an embodiment of a cable optimal path calculation method, Figure 2b Shown is a flow chart of the steps of an embodiment of a method for calculating an optimal cable path. For steps S1-S3, reference may be made to Embodiment 1, and details are not repeated here. This embodiment introduces step S4 in detail.

[0104] Step S4: Use the A star algorithm to sequentially calculate the optimal path of each cable in the cable inventory under constraint conditions.

[0105] In this embodiment, the constraint conditions are: the voltage level of the cable and the channel is consistent, and whether the current volume ratio of the channel reaches the upper limit of the allowable volume ratio. Whether the current volume ratio of the passage reaches the upper limit of the allowable volume ratio means that the sum of the cross-sectional areas of all cables passing through the passage should be less than or equal to the allowable volume ratio limit va...

Abstract

The invention discloses a cable optimal path planning method and a calculation method. The method comprises the following steps: constructing a communication relation between direct connection and close-range cable channels according to a three-dimensional digital model; searching access channels within a certain range of starting and ending point equipment of the cable, and constructing a complete equipment and channel communication relationship; and calculating the optimal path of the cable under the constraint condition by using an A star algorithm. Based on the engineering three-dimensional digital model and the cable laying working condition in the actual engineering, the optimal cable path can be planned under the condition that cable channels are complex, the most reasonable cable path can be automatically searched based on the A star algorithm, and the cable laying efficiency is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of electric power engineering cable laying, and in particular relates to a cable optimal path planning and calculation method. Background technique [0002] In large-scale power station projects, cable laying is to install cables on a given cable channel according to a given starting point device and a given end point device. There are thousands of cables in power station engineering, and the cable channels are intricate, with various channel types and connection methods. At present, cable laying is mainly based on manual planning of paths, which consumes a lot of manpower and time, and it is difficult for designers to accurately calculate the volume ratio of channels during the planning process. When construction personnel install according to the planned path, some channels will be seriously congested and some channels will be very idle. This phenomenon will affect the later installation work and schedule...
