因此,繁琐的手工记录工作成了制约水准测量效率和质量提高的一个瓶颈. 近年来微电子技术的迅速发展使测绘工作的面貌发生了重大变化,大量的高新仪器为水准记簿工作的全自动化提供了可能,PDA就是其中非常重要的一种.它集成了网络、计算、存储等功能,体积小,重量轻,有自身的操作系统,与PC数据传输非常方便. 本文针对基于PDA的电子记录手簿进行了研究,分析了PDA当前国内外的发展现状,对开发所需要的操作系统等相关技术进行了详细介绍.在各方面理论的指导下进行了系统的功能模块设计,利用Visual Studio2008平台的强大功能,对基于PDA的电子手簿进行了实现.经过测试基本达到了预期要求,提高了水准记录的效率,对测绘水准记录自动化具有一定的参考价值. 关键词:水准测量;

Abstract In the traditional work of leveling, usually uses the manual recording the way recording manual measurement data, hand level recording is a mechanical and very tedious work, the clerk must work of high tension, does not allow any negligence, otherwise it could lead to a totally geodesic rework, it is not conducive to work in data processing. Therefore, the tedious manual recording has became a bottleneck of restrict standard measurement efficiency and the quality improve. In recent years, the rapid development of microelectronics technology, makes the surveying and mapping features produced major changes, a large number of high-tech instrument is the possibility for full automation of the standard recording work, PDA is one of the important. It integrates network, compute, storage and other functions, it has small size, light weight, and it has its own operating system, it is very convenient for PC data transfer. In this paper, it research the hand book of PDA-based electronic records, and analysis the development status of the PDA at home and abroad, it is detailed introduction on the development of required operating system and related technologies. In different aspects of the theory under the guidance of a function of the system module design, use of the Visual Studio2008 platform powerful, realization of the PDA-based electronic hand book. After the test has basically reached the expectations, and improve the level of the recording efficiency, it has a certain reference value on the surveying and mapping standard record automation.
