NB-IoT NB-IoT TERMINAL FOR SAFTY CONTROL SYSTEM INCLUDING THE SAME AND METHOD FOR OPERATING THE SAME

摘要

The present invention provides an NB-IoT communication module capable of cellular communication based on IoT, a location positioning module for positioning, and a control unit for transmitting location information according to the location positioning module to a central control server. A central control server for storing an IoT terminal and at least one safety control zone to determine whether the NB-IoT terminal is out of the safety control zone, wherein the safety control zone is a first block having a predetermined size; Provided is a system including a safety control NB-IoT terminal, characterized in that a plurality of cells are continuously arranged adjacent to each other made of a safety control boundary.
