Cable automatic laying design method based on coordinate identification

Abstract

The invention discloses a cable automatic laying design method based on coordinate identification. The cable automatic laying design method is characterized in that a path diagram of cable trenches are drafted according to a set scaling proportion; a layout diagram of positions of cabinets is drafted; information of all of cables in a substation is used to form a cable inventory, and is used as an input condition of cable laying; a projection point of every cabinet on the cable trench closest to the corresponding cabinet in a vertical direction is determined, and the path between the projection points of the cabinets on the head part and the end part of every cable is calculated according to the shortest path principle; the cable lengths corresponding to the above mentioned paths are calculated; the paths and the lengths of the paths are sequentially calculated, and the laying of the cables of the whole station is completed, and a laying result is finally output. The cable automatic laying design method is advantageous in that the cable laying efficiency and the cable laying accuracy are greatly improved, the number of the cables of every cable trench is calculated, and therefore the plot ratio of every cable trench is checked conveniently, and is used to guide the optimization adjustment of the laying scheme.

Description

technical field [0001] The invention relates to the technical field of cable laying, in particular to an automatic cable laying design method based on coordinate identification. Background technique [0002] Cable laying involves multi-disciplinary design technology, which is closely related to the form of civil cable trench support, the relative position of buried pipes, the layout of electrical primary equipment, the direction of cable trench paths, the configuration of secondary professional schemes, and the statistics of secondary cables. The laying design is later than the civil construction design, which cannot be remedied, resulting in the incomplete design of cable laying, which may easily cause the engineering quantity to exceed the preliminary design plan, redundant procurement and laying of the construction unit, and other problems. [0003] At present, cables in substations are mainly divided into power cables, control cables, and communication optical cables. Du...

Problems solved by technology

[0002] Cable laying involves multi-disciplinary design technology, which is closely related to the form of civil cable trench support, the relative position of buried pipes, the layout of electrical primary equipment, the direction of cable trench paths, the configuration of secondary professional schemes, and the statistics of secondary cables. The laying design is later than the civil construction design, which cannot be remedied, resulting in the incomplete design of cable laying, easy to cause the engineering quantity to exceed the preliminary design plan, redundant procurement and laying of construction units, etc.

[0003] At present, cables in substations are mainly divided into power cables, control cables, and communication optical cables. During the design process of substations, the laying of cables is usually estimated based on experience, which has poor traceability and a large error range. The waste of cables is more prominent

Especially for projects with large voltage levels, the number of cables is large, and the crossing of cable structures is complicated. The traditional manual estimation method is not only time-consuming and laborious, but also difficult to guarantee the accuracy of the design.

At the same time, manual cable laying design can only estimate the length information of the cable, and it is difficult to calculate the volume ratio of the cable structure, which cannot be used to evaluate the rationality of the structure design and the pros and cons of the cable laying scheme
