The present application claims priority to Korean Patent Application No. 10-2023-0137584, filed Oct. 16, 2023, the entire contents of which are incorporated herein for all purposes by this reference.
The present disclosure relates to an apparatus and method for identifying a position of a moving object on the basis of the Global Navigation Satellite System (GNSS) and notifying of dangerous accidents. More particularly, the present disclosure relates to an apparatus and method for identifying a position of a moving object on the basis of the GNSS, the apparatus and method being configured to acquire precision position data of a mobile device by applying position correction data to current position information data, and the apparatus and method being configured to generate and output danger notification information on a screen of the mobile device when at least one of a distance between the measured precision position data of a mobile device and another mobile device positioned within a predetermined range, a distance between the precision position data of the mobile device and a work section, and a distance between the precision position data of the mobile device and a danger area is included in a predetermined danger range.
Generally, a position calculated by using a Global Navigation Satellite System (GNSS) receiver is expressed in three dimensions consisting of two-dimensional plane coordinates and altitude.
The position calculated by using the GNSS receiver is expressed as a three-dimensional (x, y, and z) coordinate consisting of plane coordinates and altitude. In the position calculated solely by the GNSS receiver, the accuracy of the calculated position may have an error of up to 15 m due to a system error that occurs between GNSS observations, an accidental error, and so on.
In order to calculate an accurate position with the GNSS receiver, a Differential GNSS (DGNSS) method or a Real Time Kinematic (RTK) method is used. Through this result, the GNSS receiver may acquire position information of the meter-level accuracy or the centimeter-level accuracy.
Meanwhile, due to the remarkable development of mobile devices, smartphones and tablet PCs are provided with small GPS receiving chips (circuits) embedded therein, so that a position information service capable of displaying coordinate information about a current position thereof on a corresponding data file created by cadastral surveying is capable of being realized.
Smartphones and tablet PCs operate with a plurality of embedded programs (S/W), and among the programs, there is a growing trend of developing applications, applets, or apps (APPLs or APPs) having relatively small data and relatively small step so as to realize various functions.
In addition, since smartphones and tablet PCs have an internet access function, the smartphones and the tablet Pcs are capable of compose position information including test, photos, images, cadastral boundary points, and boundary lines to file type position information, are capable of converting the file type position information into a map format in various types, and are capable of transmitting the map format in real time.
However, as mobile devices such as smartphones have been introduced, applications related to geographic information have been developed. There is a need for directly inputting and editing graphic data and databases in the field and expressing the current position by using the GNSS so as to minimize positional errors and survey inaccuracies and also to simplify a process of constructing large geographic information data and to improve accuracy so that survey maps are created more quickly and accurately and the created data and the survey maps are provided and stored.
In this regard, in Korean Patent No. 10-2022-0017264, there is provided a “METHOD AND APPARATUS OF UPDATING POSITION OF MOVING OBJECT BASED ON GNSS”.
