【摘要】 随着高等级道路需求增加和道路工程施工节奏加快，传统道路测设手段已经很难满足实际工作需要，甚至影响了工程进度和质量。本文将要研究如何以掌上电脑、全站仪等嵌入式设备为硬件平台，设计开发旨在提高道路测设工作质量和效率的、符合中国规范和国内用户操作习惯的道路测设系统，满足当前道路工程建设的需要。文章分析了开发基于掌上电脑和全站仪等嵌入式设备的中国版道路测设系统的意义；介绍了嵌入式系统的基本知识和道路测设的主要内容及流程；从最一般的情况出发，分析、推导了道路测设的相关数学模型，实际应用表明，这些模型的计算结果准确、可靠；对掌上电脑的数据库(文件)操作、多线程串口通讯进行了重点研究，设计实现了基于掌上电脑的道路测设系统；研究了徕卡全站仪的基本软件系统，对徕卡中低端全站仪机载软件通用开发平台(MMI Framework)、数据压缩存储、全站仪与微机之间数据通讯进行了重点研究，设计实现了基于徕卡中低端全站仪的道路放样软件；为弥补嵌入式设备的某些不足，设计实现了相应的桌面后(预)处理软件。本文研究成果的试用版本已经发布，目前用户已有数千人，课题的研究价值得到了充分证明。更多还原

【Abstract】 With the increment of the demand for high-level roadway and the speedup of the step for civil engineer construction, the traditional work methods can’t competent for the requirement.This paper will study how to design and develop a road setting out system, which can improve the efficiency of the road setting out, enhance the quality of the fieldwork and is accorded with Chinese criterions, answered for Chinese habit and based on the embedded devices. Consequently, sufficed the demand of civil engineer at the present time.Firstly, the paper analyzed the significance of this investigation that developed the Road Setting Out System for Chinese based on embedded devices, such as PPC, total station. Then the ABC of embedded system and the contents, follows of road setting out are introduced simply. Some important mathematics models about road setting out are analyzed and deduced from the most universal conditions. It is proved that the results of these models are exact and reliable. It gives emphasis to talk about how to develop database or file software in base of PPC and how to realize mUltithreading serial communication. Then designed and developed the Road Setting Out System based on PPC. Studied the foundation software architecture of Leica total station. And given emphasis to study the MMI Framework (the software development platform of Leica low-end and middling total station), the data compress storage and the communication between TPS and PC. Then designed and developed the Road Stake Out Application based on Leica total station. Designed and developed the post-processing and preprocessing application of the Road Setting Out System based on PC for remedy some shortages of embedded device.The demo versions of the Road Setting Out System had been released and the number of those users has arrived several thousands. And the importance of this scientific research is proved faultlessly.更多还原
