本科学生毕业论文 DINI12电子水准仪精密水准测量的精度分析 The Graduation Thesis for Bachelors Degree Precision Analysis of DINI12 Digital Level on Precise Leveling  摘 要 随着测量仪器的发展，电子水准仪在现代测量中的作用越来越重要。电子水准仪具有精度高、速度快、效率高的优势，观测成果的精度指标要比相应的观测标准要求有明显提高。本论文利用DINI12电子水准仪进行高等级水准的实验，按照国家二等水准导线测量规范要求，布设了国家二等水准路线，并利用DINI12水准仪对布设的高等级水准路线进行数据采集，分析和处理，根据水准测量的施测方法及实验数据成果检核和计算等内容，探讨了DINI12电子水准仪在进行高等级水准导线测量中是否使用方便，精度是否满足规范的要求，是否有良好的可靠性。通过对观测数据的处理和分析，按照国家高等级水准测量规范的要求，证实DINI12电子水准仪完全可以进行高等级水准测量。 关键词：电子水准仪；；； ABSTRACT With the development of measuring instruments, the digital level play an increasingly important role in modern measurement, digital level have advantages of precision,high speed,high efficiency, the accuracy indicators of observation results is more precise than corresponding standards markedly. In this paper, I use DINI12 digital level to do the experiment of high-grade leveling, according to the standard of national second-grade standard measurement strictly, to build line of second-grade leveling, and use the DINI12 digital level to acquisite, analysis and process the data of line of second-grade leveling, according to the method of leveling measurement and achievement of experiment data and computation of data, to discuss DINI12 digital level carrying on the high-grade leveling measurement whether it is easy to operate, whether satisfies precision of the standard the request, whether has the good reliability. Through processing and analysing observational data, according to demand of the standard of national second-grade leveling measurement, the DINI12 digital level definitely can carry on the high-grade leveling measurement.
