Research on Visualization of Cable Laying Process of 3D Digital Platform

Based on the design concept of THREE-DIMENSIONAL design guiding construction, this paper carried out secondary development of three-dimensional design platform to realize the visualization of secondary equipment wiring, transmission path and secondary virtual loop. Through the visualization of equipment wiring in secondary screen cabinet in Revit STD-R platform electrical equipment THREE-DIMENSIONAL display scene, it was convenient for on-site construction personnel to connect wires. The cable laying path optimization scheme under the triple constraints of cable cost, cable channel space utilization rate and shortest path is adopted to achieve the triple objectives of cable laying path optimization, cost saving and reasonable space utilization rate. The physical path and virtual loop of secondary device signal transmission can be visualized. Field debugging personnel can obtain panoramic information about the receiving and receiving devices, connecting devices (such as switches and optical configurations) and transmission paths of required signals, improving the field debugging efficiency of virtual terminals and virtual links. And through the visual section of cable laying to achieve a single cable 3D path query, can intuitively see the overall cable layout effect and the actual situation of cable turning, comprehensive consideration of the path length, cable cost, cable trench space utilization and other factors, unreasonable cable laying adjustment.
