Description

SYSTEM FOR SOLUTION OF SMART FACTORY WITH USER ORIENTATION BASED ON REAL-TIME LOCATION INFORMATION

The present invention is a system using real-time location information of objects, and more specifically, real-time location information of corresponding workers and articles using tag information representing not only human objects such as workers, but also article objects such as materials, User-oriented smart based on real-time location information that can more effectively implement follow-up processing, including processing that generates route data for time-series movement lines and shares the generated information through two-way communication with workers It is about a factory solution system.

In order to increase the efficiency of storage and management of goods, a tag (TAG) containing information that can represent the characteristics of an article is attached to an article or a moving object that moves the article, and the tag is recognized by a contact or non-contact method. A system to manage the

This system is mainly applied to the purpose of confirming the object of the goods to be loaded, moved, shipped, etc., and furthermore, through the process of recognizing the tags attached to the goods and converting the recognized information into a DB, information collection and statistics , storage, processing, etc. are configured to be followed by processing.

In order to solve the essential problems of barcodes (or QR codes) that cannot be recognized when the recognition distance is short and there is an obstacle between the reader (reader) and the tag, in recent years, NFC tags, RFID tags (RF tags), BLE (Bluetooth Low Energy) ), etc., a method that can recognize and utilize a tag at a certain remote distance in a non-contact method using the transmission and reception of wireless signals is gradually increasing.
