Description

[0001] WORKER MONITORING SYSTEM USING GLOBAL POSITIONING SYSTEM [0002]

The present invention relates to a worker monitoring system, and more particularly, to a worker monitoring system using a GPS that can confirm the position of an operator working in a factory, outdoor, and offshore structures using GPS.

It is difficult to pinpoint the location of workers working in the factory, outdoors, and offshore structures by identifying the person's perception through the markings on each area's drawings and areas. Especially, in modern high-tech offshore structures and multi-purpose vessels, there is a need for a technique to grasp accurate real-time worker position information because of complex areas and various routes.

Recently, as a result of the development of information and communication technology, a system is being developed to monitor the movement and condition of workers working in the factory, outdoor and offshore structures to protect workers and to control work efficiently.

As described in the following prior art documents, a conventional RFID-based location tracking system is composed of a main computer connected to a network with a storage device having location information in which all the train operation information and entry information of the train are stored, A communication computer for collecting and filtering the information on the line coming from the reader, a reader for collecting the RFID code and related information from the RFID tag using wireless communication, and a micro IC chip and an antenna for identifying the operator using radio frequency Tag.

However, in the worker monitoring system using RFID (Radio Frequency Identification), the recognition distance of the RFID tag is too short, and there is a concern that a large number of workers may not be recognized when moving.

Also, investment cost is high due to additional infrastructure construction, and it is difficult to maintain maintenance such as re-adjustment work due to changes in surrounding environment.
