1. A user safety monitoring method in a shaded area comprising:
an RFID recognition step of recognizing, by each of user terminals, a short-range wireless communication tag mounted on a short-range communication post installed in a work area and automatically selecting a group leader terminal from among the user terminals;
an identification information transmission step of transmitting, by group member terminals among the user terminals, identification information to the group leader terminal;
a work group information transmission step of transmitting, by the group leader terminal, work group information including the identification information received from the group member terminal and identification information of the group leader terminal to a control server;
a comparison step of comparing, by the control server, the work group information and train operation information to calculate a result value;
a step-of-determining-whether-dangerous situation-is-present of determining whether the work group is in danger, by the control server, by comparing the result value with a reference time; and
a notification step of notifying the group member terminal, the group leader terminal, and an engineer terminal of a danger situation when the control server determines that the work group is in danger.
