【摘要】：随着我国经济的高速增长,各种等级、类型的公路越来越多,但公路勘测设计作业模式几乎没有发生任何变化,仍然是外业采集、内业设计的工作方式。尤其是外业的数据采集耗时费力,而内业设计的修改与勘测不具有现时性,导致反复修改,工作效率低下。针对这样的问题开发了道路内外业勘测设计一体化系统道路内外业勘测设计一体化将成为未来发展的主要趋势,具有Windows Mobile系统的GNSS RTK控制终端有着小巧、轻便、耗电低、与桌面操作系统相似的操作方法,使得它成为一体化设计的理想承载体。本文从道路勘测设计的实际情况出发,研究了道路勘测设计工作模式及流程,将PDA平台作为户外操作移动终端,针对道路内外业的工作特点开发了集勘测、施工、设计为一体的软件系统；勘测部分通过分析差分型数据解算的工作原理,利用串口通讯与蓝牙通讯技术实现数据的实时差分解算,并将EGM-2008高程模型,线性拟合、曲面拟合模型加载到GNSS PDA的数据采集和放样软件中,使PDA可以在外业工作中获得满足实际工程需要的高程；道路设计功能将内业道路软件设计功能移植到PDA移动端,实现道路平、纵、横断面的初步设计,在外业现场就可将图形实时绘制到PDA屏幕上,并可以实现图形的放大、缩小、平移等操作；数据采集以及设计的数据利用PDA端移动数据库的管理功能,对数据进行查询、修改、添加、删除等操作,同时用SQL CE数据库将PDA端数据回传到电脑终端,电脑终端导出数据,使用配套软件将其绘制到CAD中,使内外业实现真正一体化；施工模块利用外业采集数据点,直接在外业对道路的直线、圆曲线、缓曲线等进行直接测量、计算和施工放样。本文利用RTK控制终端的功能优势,将道路勘测设计施工内外业有效结合到一起,提高了工作效率。
[Abstract]:With the rapid economic growth of our country, there are more and more highways of various grades and types, but the operational mode of highway survey and design has hardly changed, it is still the working mode of field collection and internal design. Especially in the field of data acquisition time-consuming and laborious, but the modification and survey of the internal design does not have the current nature, resulting in repeated revisions, inefficient work. In order to solve this problem, the integration system of road and outdoor surveying and design will become the main trend of future development. The GNSS RTK control terminal with Windows Mobile system is compact, portable and low power consumption. Similar to the desktop operating system, it is an ideal carrier for integrated design. Based on the actual situation of road survey and design, this paper studies the work mode and flow of road survey and design. The PDA platform is used as the mobile terminal of outdoor operation. According to the working characteristics of the road inside and outside the industry, the collection survey and construction are developed. Through analyzing the working principle of differential data solution, the investigation part realizes the real time difference decomposition of data by using serial communication and Bluetooth communication technology, and the EGM-2008 elevation model is fitted linearly. The curved surface fitting model is loaded into the data acquisition and lofting software of GNSS PDA, so that the PDA can obtain the elevation to meet the actual engineering needs in the field of work, and the road design functions transplant the software design function of the interior road to the PDA mobile terminal. The primary design of road plane, vertical and cross section can be realized, and the graphics can be drawn to the PDA screen in real time in the field of field, and the graphics can be magnified, reduced, and translated. The data acquisition and design use the management function of PDA mobile database to query, modify, add and delete the data. At the same time, the data of PDA end is transferred back to the computer terminal by SQL CE database, and the data is exported by computer terminal. The software is used to draw it into CAD to realize the real integration, and the construction module directly measures, calculates and sets out the straight line, circular curve and slow curve of the road by collecting data points from the outside industry. In this paper, the function advantage of RTK control terminal is used to effectively combine the inside and outside field of road survey, design and construction, and the working efficiency is improved.
