Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent route selection, in particular to a route scheme engineering design method based on a GIS intelligent route selection system, a medium and equipment. BACKGROUND

[0002] The route selection technology based on GIS (Geographic Information System) is an advanced method for assisting route planning and design by using computer technology, spatial information technology and database technology to collect, store, manage, analyze and visualize display geographic spatial data. Its working principle is first to obtain basic geographic information such as terrain, topography, geology, hydrology and environment through satellite remote sensing, aerial photography and other means, and to establish a three-dimensional digital model; then, using the spatial analysis functions of the GIS system, such as buffer analysis, overlay analysis and network analysis, to compare and select multiple schemes for route orientation and to evaluate the comprehensive benefits of each scheme in terms of technical feasibility, economic rationality and environmental friendliness; finally, through visualization technology, the optimal route scheme is intuitively displayed to provide a scientific basis for decision-making.

[0003] Compared with traditional route selection technology, the route selection technology based on GIS system has the following advantages: first, the data is comprehensive and accurate, the GIS system can integrate multi-source data to provide more detailed and accurate basic information and reduce the workload of field investigation; second, the analysis is efficient and intelligent, the spatial analysis capability of GIS can quickly process complex geographic information to realize multi-factor and multi-target optimization decision-making and improve the efficiency of route selection; third, the visualization is strong, three-dimensional scene display makes route planning more intuitive and facilitates multi-party communication and cooperation; fourth, it is flexible and adjustable, the GIS system supports dynamic adjustment of route scheme to adapt to design change requirements; fifth, it is environmentally friendly and sustainable, through comprehensive assessment of environmental impact, it helps to select more environmentally friendly route scheme and realizes sustainable development. In short, the route selection technology based on GIS system represents the development direction of modern route planning and provides strong technical support for route design in the fields of transportation, power and communication.

[0004] In the traditional route selection design process based on the GIS system, the designer often performs the flagging operation according to simple business rules such as the height from the rail surface to the ground, to preliminarily define the boundary range of the roadbed, the bridge and the tunnel. However, such a method has significant limitations, that is, the influence of the topographic features near the boundary area and the existing structures cannot be fully considered. In view of the fact that the roadbed, the bridge and the tunnel are usually designed in parallel, there is a lack of effective information communication and cooperation among different professionals, and thus coordination problems such as boundary mileage conflict and mileage discontinuity frequently occur. As a result, the design scheme of the roadbed, the bridge and the tunnel often needs to be frequently adjusted in the subsequent deepening process. In order to solve these problems, the design team has to repeatedly adjust, which not only significantly reduces the design efficiency, but also may lead to the fact that the final scheme deviates from the optimal solution to some extent, and presents a compromising feature. Therefore, the traditional route selection design method is not competent in dealing with complex geographical environment and multi-professional collaborative design. SUMMARY
