PURPOSE: A central managing system using an Internet communication network and a method thereof are provided to maintain and manage environments of many rooms located in wide area by managing internal environments of the rooms in the center with a remote control using an Internet communication network. CONSTITUTION: A room sensor(30) is mounted in each room(40), receives an environment signal for displaying an internal state of the room, converts the environment signal into a digital signal, generates, and outputs environment information. A local area sensor(20) is connected to each room sensor(30) using a local area network, scans many room sensor(30) at a predetermined time interval, receives environmental information generated in each room sensor(30), and outputs an identification code of the room sensor(30) and the environmental information. A main sensor(10) is connected to the local area sensor(20) through a TCP/IP protocol, receives the identification code of the room sensor(30) and the environmental information being transmitted from each local area sensor(20), stores the code and information in a DB(13), and displays the stored information. |
