SPATIAL INFORMATION SITE SUPPORT SYSTEM OF SURVEY REFERENCE POINT USING NFC TAG OR SMART TAG

摘要

The present invention relates to a national level reference point measuring device (310) using equidistant observation of public land, including a laser (320) distance measuring device for remote and accurate distance calculation, a primary lens for focusing an object and a line of sight, an automatic level device for automatically detecting a bubble tube when the bubble tube is within an allowable radius, a liquid display device displaying an appropriate distance to an observer, a data connection cable for transmitting and receiving data, an eyepiece for observation, a data storage device for calculating distance data and storing processed data, a data processing device for distance calculation and feature information processing, a sight line device for obtaining an observation value in response to a scale, and an objective lens for magnifying a remote object. The measuring device (310) includes a metering target that reflects the emitted laser (320) for accurate position metering and the metering target includes a connecting member (100) configured to be adjustable in angle; and a reflecting member (200) including a needle portion having a sharp end and coupled to the connecting member (100) to indicate a measuring target, a frame (220) coupled to the other end of the needle portion, and a reflecting plate (230) provided on the front surface of the frame (220) and indicating a metering reference point. The reflecting plate (230) uses an NFC or smart tag contamination-prevented by means of predetermined contamination prevention means in the spatial information site support system of a survey reference point.;COPYRIGHT KIPO 2019
