【摘要】:近年來,隨著大地測量的發(fā)展,特別是衛(wèi)星定位技術(shù)的廣泛應(yīng)用,傳統(tǒng)大地測量的理論和方法都發(fā)生了革命性的變化,衛(wèi)星定位技術(shù)大有取代常規(guī)大地測量的趨勢。但是,在精確傳遞高程和建立高程控制網(wǎng)方面,幾何水準(zhǔn)這種古老的測量方法,至今還不能完全為現(xiàn)代的空間技術(shù)所取代。 幾何水準(zhǔn)測量是目前進(jìn)行高精度水準(zhǔn)測量的唯一方法。在幾何水準(zhǔn)測量儀器中,主要使用氣泡式的精密水準(zhǔn)儀、自動安平的精密水準(zhǔn)儀、數(shù)字水準(zhǔn)儀以及相應(yīng)的銦瓦合金水準(zhǔn)尺[2]。 隨著經(jīng)濟(jì)社會的發(fā)展,數(shù)字水準(zhǔn)儀越來越多的應(yīng)用到測繪單位的生產(chǎn)實(shí)踐中。與傳統(tǒng)的光學(xué)水準(zhǔn)儀相比,它具有如下優(yōu)點(diǎn):讀數(shù)客觀、精度高、速度快、效率高、操作簡單、數(shù)據(jù)便于輸入計(jì)算機(jī)等。然而,數(shù)字水準(zhǔn)儀原始觀測數(shù)據(jù)的記錄一般是由固化在儀器內(nèi)部的數(shù)據(jù)記錄程序完成的。由于存在不同儀器生產(chǎn)商,數(shù)據(jù)的記錄模式也各不相同,不同的儀器生產(chǎn)廠家對應(yīng)不同的數(shù)據(jù)結(jié)構(gòu)。這些原始的記錄數(shù)據(jù)不能夠作為水準(zhǔn)測量的最終成果,都需要進(jìn)一步處理。 因此,結(jié)合我在測繪生產(chǎn)單位的實(shí)踐及生產(chǎn)要求確立了本文的研究內(nèi)容如下: 1.分析比較常用的高程測量手段和方法(幾何水準(zhǔn)測量、三角高程測量、GPS高程測量、物理高程測量),說明幾何水準(zhǔn)測量的必要性。 2.便攜設(shè)備(PDA、手機(jī))與Leica DNA03數(shù)字水準(zhǔn)儀的無線通信方法研究。在實(shí)際的水準(zhǔn)測量作業(yè)中,現(xiàn)有的系統(tǒng)是采用手簿與儀器之間有線連接,給外業(yè)水準(zhǔn)測量工作帶來一定的不便。 3.便攜式水準(zhǔn)測量數(shù)據(jù)采集與處理系統(tǒng)的設(shè)計(jì)(包括PDA端的數(shù)據(jù)采集系統(tǒng)和PC端的數(shù)據(jù)處理及平差系統(tǒng))。 4.結(jié)合實(shí)際項(xiàng)目檢驗(yàn)該系統(tǒng)的實(shí)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.
