The present invention relates to a system for collecting a worker's location information in an IoT-based port facility, which generates a worker's action radius information and expected movement route information in a port by using schedule information of the worker located in the port, to be able to estimate approximate places where each worker needs to be. In a system for collecting a worker's location information in an IoT-based port facility, performed by a management server, the management server includes: a location information collecting unit which collects location information from a terminal or wearable device possessed by a worker located in a port; a derivation unit which generates the work's action radius information and expected movement route information in the port by using schedule information of each worker; an information updating unit; an information providing unit; and a management unit.
