【摘要】：近年来,随着大地测量的发展,特别是卫星定位技术的广泛应用,传统大地测量的理论和方法都发生了革命性的变化,卫星定位技术大有取代常规大地测量的趋势。但是,在精确传递高程和建立高程控制网方面,几何水准这种古老的测量方法,至今还不能完全为现代的空间技术所取代。几何水准测量是目前进行高精度水准测量的唯一方法。在几何水准测量仪器中,主要使用气泡式的精密水准仪、自动安平的精密水准仪、数字水准仪以及相应的铟瓦合金水准尺[2]。随着经济社会的发展,数字水准仪越来越多的应用到测绘单位的生产实践中。与传统的光学水准仪相比,它具有如下优点：读数客观、精度高、速度快、效率高、操作简单、数据便于输入计算机等。然而,数字水准仪原始观测数据的记录一般是由固化在仪器内部的数据记录程序完成的。由于存在不同仪器生产商,数据的记录模式也各不相同,不同的仪器生产厂家对应不同的数据结构。这些原始的记录数据不能够作为水准测量的最终成果,都需要进一步处理。因此,结合我在测绘生产单位的实践及生产要求确立了本文的研究内容如下： 1.分析比较常用的高程测量手段和方法(几何水准测量、三角高程测量、GPS高程测量、物理高程测量),说明几何水准测量的必要性。 2.便携设备(PDA、手机)与Leica DNA03数字水准仪的无线通信方法研究。在实际的水准测量作业中,现有的系统是采用手簿与仪器之间有线连接,给外业水准测量工作带来一定的不便。 3.便携式水准测量数据采集与处理系统的设计(包括PDA端的数据采集系统和PC端的数据处理及平差系统)。 4.结合实际项目检验该系统的实用性。
[Abstract]:In recent years, with the development of geodesy, especially the wide application of satellite positioning technology, the theory and method of traditional geodetic survey have undergone revolutionary changes, and satellite positioning technology has taken the place of conventional geodetic survey.However, the ancient measurement method of geometric leveling can not be completely replaced by modern space technology in the aspect of accurately transmitting elevation and establishing elevation control network.Geometric leveling is the only method for high precision leveling.In the geometric leveling instrument, the bubble type precision level, the automatic leveling precision level, the digital level and the corresponding indium tile alloy leveler are mainly used.With the development of economy and society, digital level is applied more and more to the production practice of surveying and mapping unit.Compared with the traditional optical level, it has the following advantages: objective reading, high accuracy, high speed, high efficiency, simple operation, easy to input the data into the computer and so on.However, the recording of the original observation data of the digital level is generally completed by the data recording program which is solidified inside the instrument.Because of the existence of different instrument manufacturers, the data recording modes are different, and different instrument manufacturers correspond to different data structures.These raw recorded data cannot be regarded as the final result of leveling and need to be further processed.Therefore, combined with my practice in surveying and mapping production units and production requirements to establish the content of this study as follows:1.This paper analyzes and compares the commonly used means and methods of height measurement (geometric leveling, trigonometric leveling, GPS leveling and physical leveling), and explains the necessity of geometric leveling.2.The wireless communication method between portable device PDAs and Leica DNA03 digital level is studied.In the actual leveling operation, the existing system uses the wired connection between the manual and the instrument, which brings some inconvenience to the field leveling work.3.The design of portable leveling data acquisition and processing system (including PDA data acquisition system and PC data processing and adjustment system).4.The practicability of the system is tested in combination with the actual project.
