At this time, the location of the underground ship marker, the underground buried object, and the ground information transmitted to the management system server are stored in the database server of the management system server.

Also, in the case of a marker installed on the underground line where information is installed when information is retrieved, location information, underground objects, and ground information are transmitted to the user terminal and a dedicated application is executed.

At this time, in the case of the dedicated application, the path is received by receiving the GPS position continuously, and the information of the marker is additionally transmitted to the underground line embedded in the front. When the dedicated application is terminated, the user terminal receives a command for acquiring other information It remains in standby mode until

Here, information recognition means such as an NFC, an RFID, an RFID, a wireless LAN, a frequency generator (Wi-Fi), a Bluetooth device or the like is designed to transmit a signal only when a signal is inputted from the outside.

In this way, other measurement methods described up to now have been detected by using dedicated equipment, and tags such as RFID can only be measured with a passive tag at a short distance. However, in the case of the RFID tag such as the underground using the hybrid energy hubbing- The markers can be used as measuring devices for underwater markers by using additional equipment based on general wireless communication devices (for example, smart phones and tablet PCs) according to the attached communication devices.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims and their equivalents. Of course, such modifications are within the scope of the claims.
