Generally, in a factory that manufactures products, process monitoring is performed to improve the quality of products and to manage safety and facilities.
In this process monitoring, a part of the Internet technology that has brought about a remarkable technological development has recently been applied, and in order to develop the function of the process monitoring, researches to integrate the Internet of things have been actively conducted.
Internet of Things (IoT) is an intelligent technology and service that connects all objects based on the Internet and communicates information between people, things, things and things.
The term refers to the fact that Kevin Ashton, director of the Auto-ID Center at the Massachusetts Institute of Technology (MIT) in 1999, will be using the RFID (radio frequency identification) and other sensors And it has been popularized since it was used for market analysis and so on.
The Internet is more advanced than Internet or mobile Internet based on existing wired communication, and devices connected to the Internet communicate with each other without any human intervention. The concept of M2M (Machine to Machine) is similar to the conventional ubiquitous and M2M (Machine to Machine) in that things do not depend on humans. It evolved into a concept that interacts with all the information of reality and virtual world as well as objects
Techniques for implementing this include 'sensing technology' for obtaining information from objects of the type and environment, 'wired and wireless communication and network infrastructure technology' for supporting objects to be connected to the Internet, information suitable for various service fields and forms 'Service interface technology' that processes and processes or fuses various technologies is the key, and 'security technology' is also necessary to prevent hacking or information leakage of the Internet components of a large amount of data and the like.
'Smart Key' that can automatically start the car door lock when it is accessed with the key, 'Smart Grid' that efficiently manages the energy including electricity, gas or water and sewage, The things that are being utilized are the Internet.
Objects The objects that make up the Internet collect data about themselves and related data according to their own functions. For example, the air conditioner can collect the current temperature and the target cooling temperature, and the door of the building can identify how many people have passed. Since things constantly produce data, vast amounts of data are processed within the network. Based on this, the object network can provide various application services such as smart city, smart home, smart office, healthcare, smart mirroring and so on.
