While connecting to the gateway terminal device through wired / wireless communication network, it enables efficient integration control and remote control of remote facilities, but processes the raw or source data of remote facilities stored in the shared memory of the terminal device to enable the cloud server. The unrecognized or insignificant data relates to a gateway terminal device for remote integrated control and control of an IoT-based facility including a data processing function that prevents its transmission.

In general, the Internet of Things (IoT) is an intelligent technology and service that connects all things based on the Internet and communicates information between people and things, things and things, and it is called IoT after the initials of English. Sometimes abbreviated.

The Internet of Things is a more advanced stage than the Internet or mobile Internet based on the existing wired communication, and facilities connected to the Internet exchange and receive information with each other without human intervention, which means that objects communicate without relying on humans. In terms of exchanging, there are similarities to the existing Ubiquitous or M2M (Machine to Machine), which is an intelligent communication, but by extending the concept of M2M to the Internet, it interacts with all information in the real world and virtual world as well as things. It can be seen as an evolutionary stage.
