Detailed Description
The following describes in detail a specific embodiment of the cable laying method of the present invention with reference to the drawings.
Referring to fig. 1, the process of laying the cable is performed after determining parameters of a starting point device, an end point device and a cable bridge, the starting point device and the end point device are designed by related thermal control professionals and are matched with civil engineering to determine the parameters of the position, the size, the model and the like of the device. The cable bridge is designed by mechanical speciality, and after parameters are determined, the parameters are stored in a database together with a starting point device and a terminal point device so as to be convenient for reading and using data during cable laying.
The electric secondary cable laying method comprises the following steps:
(1) the starting point, the end point and the model of the cable are determined, and relevant parameters can be read from a drawing or extracted from a database. And obtaining the outer diameter, the type and the like of the cable from the cable parameter information, wherein the information is related to the KKS code of the equipment. The KKS codes are filed in a cable inventory, and the equipment positioning information is also stored in a civil engineering drawing.
(2) The type and coordinates of the cable tray are determined, and nodes on the cable tray are determined. The cable bridge information is designed in the mechanical profession, nodes on the bridge are defined in a graph or a database, and after relevant data are read out, preparation is carried out for a cable laying path.
(3) And judging whether a bridge path exists between the starting point node and the end point node of the cable or not by passing through nodes corresponding to the starting point and the end point of the cable, and if so, finishing the laying of the cable. And after part of cables are finished, returning the cable information to the cable database.
(4) If no bridge path is present: traversing the nodes corresponding to the starting points, judging whether effective nodes exist or not, enabling effective paths to exist between the effective nodes and the starting points on the bridge, namely finding a bypass, dividing the paths into two parts, and forming a new cable path through the effective nodes. If the nodes corresponding to the starting points cannot form effective nodes, the cable laying fails, and finally the cable laying can be corrected through manual work or modification of the bridge.
(5) And after the cable path is calculated, calculating whether the bridge parameters of the effective path are matched with the parameters of the cable or not until all effective nodes are compared, and if not, returning the cable laying failure. The matching principle is that the available width of the bridge rack channel on the bridge rack bracket is larger than the outer diameter of the cable. The usable width is the product of the stent width and the volume fraction minus the used width.
(6) And (4) recording bridge frame information and channel information, taking the effective node as a starting point of the cable, and returning to the step (3) until the cable laying is finished.
(7) And after the laying is finished, taking the length of the path of the effective node as the length of the cable. When the bridge frame comprises a plurality of layers of supports, the data of the nodes comprise support layer information, and the height information of the support layers is added into the length of the cable when the length of the cable is calculated.
Referring to fig. 2, the process of completing cabling is implemented by software in conjunction with a drawing tool. The processing of the set of data is realized by the allocation of the NODE points of the NODE set.
Starting from the laying point, if the starting point is, the starting point information is written into the inaccessible node set firstly. And when the laying algorithm is carried out, selecting the NODE with the shortest path from the inaccessible NODE set as the current NODE, and removing the NODE from the inaccessible NODE set. If the NODE is not the end point, selecting the effective associated NODE ConNode with the shortest path from the NODEs connected with the NODE (the effective associated NODE means that the bridge capacity of the path can put down the current cable and the NODE is not visited), and adding the ConNode into the unvisited NODE set. The remaining associated NODEs of the NODE are then written to the set of inaccessible NODEs and the NODE is tagged with an accessed flag. When the next path is searched continuously, the above operation is executed circularly until the NODE is the end point.
Referring to fig. 3, after the bracket is installed on the cable bridge, different path calculation methods are formed, and when the number of layers and the width are judged to form different paths under different conditions, the method is suitable for cable laying at different starting points and end points.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
