It relates to a system that provides the latest and accurate information by more easily reflecting the fluctuations in the field.

In general, the line used as a reference for marking a specific location on a map is the meridian and equator line passing through Greenwich in England as the starting point, and in Korea, the origin of longitude and latitude is determined by the National Geographic Information Institute of Suwon. Put

However, in an area far from the origin, it is difficult to perform a survey from a corresponding location, so a survey reference point is provided at a certain location in each area across the country.

The survey reference point is used as a coordinate point for mapping, construction, and civil engineering drawings and surveying, and to ensure the accuracy of the survey, it is indicated by coordinates, etc., according to the survey standard prescribed by law. Triangular points, level points, multi-angle points, gravity points, and magnetic points belong to the control point.

A typical survey reference point consists of boulders that form a crosshair in the upper part and bury the lower part in the ground to fix it. Survey control points are managed by the central government or by the competent authorities of each province.

As an example of a known technology, Korean Patent Registration No. 10-1177551 discloses a support structure that is buried in the ground but has a column insertion groove in the upper center and is made of one of concrete or stone, and the lower part is in the column insertion groove. It is inserted and a pin insertion groove is formed in the center of the top, and a column member made of any one material selected from synthetic resin, steel, concrete, and stone, and a cross-shaped mesh wire is formed at the top of the pin insertion groove and synthetic resin or steel. A pin member made of one of the selected materials, an anchor member installed around the outer circumferential surface of the column member and having a plurality of ribs formed on the outer circumferential surface, and concrete installed around the column member and supporting structure with the anchor member installed. Construct control point markers containing layers.

As another example, in Korean Utility Model No. 20-0359649, the main body of the reference point mark with a certain mark on the top so as to mark the measurement reference point on the surface, and the main body of the reference point mark are mounted at a predetermined position on the main body of the reference point, and It includes a survey information storage means including an IC chip that digitally records survey-related information including a unique ID and coordinate values for the survey, and the survey-related information stored in the survey information storage means can be read in a contactless manner by a separate reader. A survey control point marker is constructed so that it can be used.

As another example, Korean Patent Registration No. 10-1019674 discloses a disk-shaped body having a disk shape as a whole and having a hollow penetrating the upper and lower portions of the central portion, an RFID tag installed inside the disk-shaped body and storing measurement information. , An antenna connected to the RFID tag and installed in an annular shape along the inside of the disk-shaped body, and a plurality of fixing pins protruding from the lower surface of the disk-shaped body toward the ground, and the survey information stored in the RFID tag is read by the RFID reader. And, a survey control point electronic sign installed on the ground is constructed so that the existing buried survey control point is located in the hollow.

Korean Patent Registration No. 10-1177551 (2012.08.27) Korean Utility Model Registration No. 20-0359649 (2004.08.21) Korean Patent Registration No. 10-1019674 (2011.03.07) Korean Patent Registration No. 10-1010334 (2011.01.25)

The downside is that the process is very cumbersome.

Accordingly, in recent years, an electronic survey reference point has been provided that allows an electronic tag storing survey reference point information to be embedded in a survey reference point to obtain information in a non-contact manner by a reader so that information can be viewed more easily in the field.

On the other hand, in general, the location of the survey reference point changes slightly due to various factors such as changes in the crust and topography, so the location of the survey reference point is periodically tracked by the GPS station in each region operated by the National Geographic Information Service. If the tolerance is out of the tolerance, the new coordinates of the survey points installed nationwide are calculated based on the amount of displacement, and the existing information notified to the competent authority is adjusted to the changed information.

However, the conventional electronic survey reference point cannot grasp the error between the information newly calculated and announced by the GPS regular observation station and the information previously stored in the electronic tag at the site, and the user cannot easily modify the information stored in the electronic tag at the site. There is a problem that the management process is very cumbersome, such as confusion between the information stored in the information and the information notified and provided by the competent authority or the inability to provide the latest and accurate information.
