【摘要】：本文的主要內(nèi)容是高精度局部重力場(chǎng)計(jì)算平臺(tái)的集成與開(kāi)發(fā)。 目前，針對(duì)大地測(cè)量，尤其重力數(shù)據(jù)處理方面的軟件雖然并不算少，但是很少見(jiàn)到功能全面的系統(tǒng)性大型軟件。為了改善這一狀況，課題組研發(fā)了高精度局部重力場(chǎng)計(jì)算平臺(tái)。 高精度局部重力場(chǎng)計(jì)算平臺(tái)是一套適用于重力場(chǎng)數(shù)據(jù)處理、局部重力場(chǎng)逼近和大地水準(zhǔn)面精化等方面研究和工程計(jì)算工作的軟件平臺(tái)。平臺(tái)采用面向?qū)ο蟮哪K構(gòu)架，使用Visual C++6.0和Visual Fortran95混合編程開(kāi)發(fā)，功能體系相對(duì)獨(dú)立，用戶在使用軟件的過(guò)程中不需要借助其他工具。 高精度局部重力場(chǎng)計(jì)算平臺(tái)的開(kāi)發(fā)，其意義在于改善科研工作人員的工作效率與方法，提高重力場(chǎng)數(shù)據(jù)處理的軟件水平，填補(bǔ)系統(tǒng)性計(jì)算平臺(tái)軟件稀缺的這一空白。平臺(tái)包含了多項(xiàng)理論技術(shù)創(chuàng)新，對(duì)傳統(tǒng)局部重力場(chǎng)技術(shù)和算法進(jìn)行了大量的改進(jìn)，能夠更加適應(yīng)厘米級(jí)大地水準(zhǔn)面精化和高精度局部重力場(chǎng)逼近的新技術(shù)要求。 軟件是在利用模擬數(shù)據(jù)基礎(chǔ)上開(kāi)發(fā)的，本文重點(diǎn)介紹了集成后的軟件功能實(shí)現(xiàn)，并通過(guò)實(shí)測(cè)數(shù)據(jù)對(duì)軟件進(jìn)行測(cè)試，增強(qiáng)軟件的實(shí)用性，以期滿足工程化應(yīng)用需求。本文最后總結(jié)出軟件本身存在的問(wèn)題與今后再開(kāi)發(fā)可能遇到的問(wèn)題，并對(duì)部分問(wèn)題提出了解決方案。 課題組自2008年以來(lái)，逐漸發(fā)展并完善了該軟件1.0版本。應(yīng)技術(shù)革新要求，現(xiàn)需要將平臺(tái)軟件結(jié)構(gòu)重新規(guī)劃后集成開(kāi)發(fā)，并對(duì)其功能以及部分接口重新設(shè)計(jì)。然后對(duì)系統(tǒng)整體進(jìn)行詳細(xì)的測(cè)試，并分析其結(jié)果。本論文主要對(duì)該軟件的集成開(kāi)發(fā)及整合進(jìn)行介紹。本課題的研究?jī)?nèi)容為更新軟件框架，以及數(shù)據(jù)接口和人機(jī)交互界面，整合歸并算法后重新集成計(jì)算平臺(tái)。集成后，由于對(duì)軟件系統(tǒng)進(jìn)行了改動(dòng)，因此需要測(cè)試確定其可靠性以及穩(wěn)定性。本課題中，我們將使用實(shí)際數(shù)據(jù)，，設(shè)計(jì)整套計(jì)算流程，熟悉軟件操作并進(jìn)行軟件測(cè)試。 測(cè)試結(jié)果經(jīng)分析，軟件的重新集成后，可靠性和穩(wěn)定性均能夠達(dá)到要求水平，能夠滿足科研與工程任務(wù)需要。
[Abstract]:The main content of this paper is the integration and development of high-precision local gravity field computing platform. At present, there are few software for geodesy, especially gravity data processing, but there are few systematic large-scale software with comprehensive functions. In order to improve this situation, a high precision local gravity field calculation platform has been developed. The high precision local gravity field computing platform is a software platform suitable for the research and engineering calculation of gravity field data processing, local gravity field approximation and geoid refinement. The platform adopts the object-oriented module framework, uses Visual C 6.0 and Visual Fortran95 mixed programming development, the function system is relatively independent, the user does not need to use other tools in the process of using the software. The development of high precision local gravity field computing platform is significant to improve the efficiency and method of scientific research staff, to improve the software level of gravity field data processing, and to fill the gap of software scarcity in systematic computing platform. The platform includes many theoretical and technical innovations, and a large number of improvements have been made to the traditional local gravity field techniques and algorithms, which can better meet the new technical requirements of centimeter level geoid refinement and high precision local gravity field approximation. The software is developed on the basis of simulated data. This paper mainly introduces the realization of the integrated software function, and tests the software through the measured data to enhance the practicability of the software in order to meet the needs of engineering application. Finally, this paper summarizes the problems existing in the software itself and the problems that may be encountered in the future re-development, and puts forward some solutions to the problems. Since 2008, the research group has gradually developed and improved the 1.0 version of the software. In response to the requirement of technological innovation, it is necessary to redesign the software structure of the platform after the integration development, and redesign its functions and some interfaces. Then the system as a whole is tested in detail, and the results are analyzed. This paper mainly introduces the integrated development and integration of the software. The research content of this subject is to update the software framework, data interface and human-computer interaction interface, integrate the merging algorithm and re-integrate the computing platform. After integration, the software system needs to be tested to determine its reliability and stability. In this topic, we will use the actual data, design the whole calculation process, familiar with the software operation and software testing. The test results show that the reliability and stability of the software can reach the required level and meet the needs of scientific research and engineering tasks.
