Kern E2/DM503/R48电子速测仪在1983年的国际测量工作者联合会上首次展出。1984年英国诺丁汉大学采矿工程系对该仪器系统进行了鉴定。本文叙述了Kern E2电子经纬仪,DM503光电测距装置及R48电子野外记录器的工作原理,总结性地介绍了野外鉴定的成果,野外鉴定评价的内容包括:野外基线,野外测试网和一些工程测量任务,如矸石山测量,采矿沉陷测量等。一些野外测量成果自动记录在R48数据记录器上,然后传输到室内微机系统中进行自动数据处理和绘图。本文对该仪器的性能和在测量工程中的适用性作了评论。
The Kern E2 / DM503 / R48 electronic speedometer was first shown at the International Federation of Surveyors in 1983. In 1984 the British Department of Mining Engineering, University of Nottingham, the instrument system was identified. This paper describes the working principle of Kern E2 electronic theodolite, DM503 photoelectric distance measuring device and R48 electronic field recorder, summarizes the results of the field identification, field evaluation include: field baseline, field test network and some engineering measurements Tasks, such as waste rock measurement, mining subsidence measurement. Some field measurements are automatically recorded on the R48 data logger and then transmitted to an in-home computer system for automated data processing and plotting. This article reviews the performance of the instrument and its applicability in measurement engineering.
