【摘要】：为了对辽宁省高速公路养护信息进行更好的管理,也是随着交通部门提出的“以信息化带动交通现代化”的方针,辽宁省高速公路养护信息系统将要对养护数据进行数字化的管理,结合GIS平台建立相应的信息系统,摒弃传统的数据模型,使得空间定位、属性管理更加高效、便捷,结合空间要素与属性的“双向”查询、专题养护数据的统计、缓冲区、叠加等空间分析,弥补传统系统的管理不足之处,提高养护管理的技术水平。本文主要做了以下的研究：(1)在辽宁省高速公路养护信息系统的需求分析下,采用基于C#的ArcEngine开发环境,采用Geodatabase数据模型,实现空间数据与属性数据的无缝对接。同时充分利用GIS平台的空间分析、显示和专业模型在各方面的优点,将它们集成到系统中,保证了养护信息的系统化管理。(2)明确高速公路养护的内容、情况、养护工程分类、作业,以及评价模型的计算公式和如何依据评价模型做出养护决策。(3)通过线性参考系统和动态分段技术,改变原有的“节点-弧段”模型在线性要素上的应用,使用线性参考模型,将2维坐标转化为1为相对坐标,减少数据冗余的同时,提高系统的运行效率。基于动态分段技术,将高速公路网转化为高速公路路径集,属性事件表与空间数据分离,通过路径编码将其关联,实现了多源数据的统一显示、管理。(4)对于生成的高速公路路径,可以实现将系统中的事件通过事件表转化为图层,从而进行显示,同时还可以进行高速公路路径的识别和查找等操作。该系统还实现了其他多种功能,如对数据的基础管理；实现了对高速公路路径网和高速公路出入口查询管理；实现了对高速公路沿线设施的查询管理；实现了对养护数据的查询管理,及一些操作功能。
[Abstract]:In order to better manage the information of highway maintenance in Liaoning Province, it is also the policy of "using information to drive traffic modernization" put forward by the traffic department. Liaoning Provincial Expressway maintenance Information system will be digital maintenance data management, combined with the GIS platform to establish the corresponding information system, abandon the traditional data model, make space positioning. Attribute management is more efficient, convenient, combined with spatial elements and attributes of the "two-way" query, thematic maintenance data statistics, buffer, superposition and other spatial analysis, to make up for the traditional system management deficiencies. In order to improve the technical level of maintenance management, this paper mainly does the following research: 1) under the requirement analysis of Liaoning Provincial Expressway maintenance Information system, the ArcEngine development environment based on C # is adopted. The Geodatabase data model is adopted to realize the seamless connection between spatial data and attribute data. At the same time, the advantages of spatial analysis, display and professional model of GIS platform are fully utilized. Integrate them into the system to ensure the systematic management of maintenance information. 2) clear the content of highway maintenance, situation, maintenance engineering classification, operation. And the calculation formula of evaluation model and how to make maintenance decision according to evaluation model. Through linear reference system and dynamic segmentation technology, the application of the original node-arc model to linear elements is changed. By using the linear reference model, the 2-D coordinate is transformed into a relative coordinate, which reduces the data redundancy and improves the running efficiency of the system. Based on the dynamic segmentation technology, the expressway network is transformed into the freeway path set. Attribute event table is separated from spatial data, which is associated with it by path coding. The unified display of multi-source data is realized, and the generated freeway path is managed. The event in the system can be transformed into a layer through the event table, which can be displayed. At the same time, it can also be used to identify and find the freeway path. The system also realizes a variety of other functions. Such as the basic management of data; The query management of expressway route network and expressway entrance and exit is realized. The inquiry management of the facilities along the highway is realized. The query and management of maintenance data and some operation functions are realized.
