【摘要】 随着我国公路建设的蓬勃发展,各等级公路数量不断增多,公路勘测设计的任务也日益繁重。传统的道路测量内外业的分开,道路实地勘测与设计调整与路线调查的分开,大大降低了道路建设的工作效率,而且很多勘测设计数据得不到实时准确的实地对照修改,增加了设计的盲目性而且需要反复修改。PDA作为一种新兴产品,经过十几年的发展,已经日益成熟,体积小,可靠性高,重量轻,耗电少,功能强大,操作简单,操作系统可视化程度好,符合人们使用Windows的习惯,价格便宜,适合随身携带、供电时间长而且也能实现所测图形的实时显绘等优于笔记本电脑的优点,所以基于PDA的道路工程勘测设计软件具有一定的市场前景,将真正实现道路勘测设计一体化。因此,本文在对多个勘测设计单位调研和总结的基础上,针对控制测量、碎步测量、平纵横的设计与调整、纵横断测量、3D测设和路线的各种调查等,研究和开发了基于PDA的道路工程勘测设计一体化系统软件,系统具有良好的输入、输出、管理分析等功能。系统主要分为五大模块:数据管理模块、控制测量和碎步测量模块、设计模型模块、测设模块、路线调查模块等。能够完成初步设计方案的放线、实地调线、纵横断面测量、沿线的各种调查数据的采集等,几乎能够在实地一次性完成道路及线形构造物勘测设计工作的全部外业工作。可使用几乎各种测量手段进行测量、放线,且PDA与测量仪器采用蓝牙无线传输。实地定线和图上定线在实地紧密结合,可以尽量避免事后调线引起的断链。并且在算法和作业方式上有很大创新,不仅能很大程度满足勘测设计单位的需要,大大提高工作效率,而且为勘测设计成果及管理的自动化、智能化、一体化、实时化、可视化等奠定了基础。更多还原

【Abstract】 With the developing of our country’s highway, the number of the various road is more and more. So the Survey and Design task of road is increasingly arduous. The traditional method is that outside surveying and inside designing are separated. Which resulted in reducing efficience and much more data of surveying and design could not accurately modify comparing to the site. So this increases the blindness of design and need modify again and again.PDA, as a new product, developing more than 10 years, has become increasingly maturer, smaller size, higher reliability, lighter weight, less power consumption, larger function, simpler operation, the better visualization of operating system, cheaper and more suitable for carrying. And it’s in keep with the use of Windows and it has graphics and real-time display and their power can last a long time, which madea PDA better than portable computer. So the system of road survey and design based on PDA has much more market and will rearly realized one-shot job between survey and design.Therefore, on the base of investigation on surveying and design knowledge of many surveying units and analysis a lot of esisting softwate about surveying and designing. Airmed to control survey, choppy stride survey, road design and adjust, profile and cross section surveyin, 3D survey and investigate of road and so on. The paper studies that surveying and designing system in road engineering based on PDA. Which is good in input and output and management analysis capabilities and which has five modules, data management module, control survey module, design module, 3Dsurveying module and investigate module of road. The system can complete survey and modify program and profile and cross section surveying and various investigates of preliminary design, all the work of road surveying and designing. Almost all can be used to survey. Because of its constituted between blueprint design and spot design, designers can avoid chain breaking precisionly. So it is good to enhance efficiency of surveying and designing and satisy the need of surveying and designing units. What is more, it provides a stability foundation for automation, intelligent, integrated, real-timevisual.更多还原
