The present invention relates to a smart power saving system of a building. More specifically, the lighting control system has been applied to save energy in buildings, but the energy saving effect is insufficient as a load occupied by the lighting in the whole building. Outlet loads have not been able to apply control systems due to integrated piping / wiring problems. Therefore, the present invention detects the presence or absence of the user''s room for each room in the building in real time, and automatically turns on / off the lighting load and the power outlet load to achieve maximum power saving, If there is, the administrator can visually and acoustically check the intrusion with SMS, and collect and use the information of lighting load and outlet power of each room from the central server for monitoring and remote control. The present invention relates to a smart power saving system for a building that aims to enable control and at the same time monitor a lighting and outlet energy use in a building and enable remote control in a remote monitoring controller. Therefore, the present invention is to achieve the above object, the infrared sensor 11 for detecting the movement of the room, the illumination sensor 12 for detecting the brightness of the room, the buzzer 13 for emitting an alarm sound, and the smart switch ( 20) and the wireless transmission and reception unit (SS) for transmitting and receiving wirelessly, the network terminal 14 for transmitting and receiving connected to the central server 42 by wire, and the microcontroller (MC) to manage and control the above Smart sensor 10 and composed of; The manual button 21 for turning on / off the lighting of the room, the selection button 22 for selecting the setting in the automatic / manual / security mode and setting the setting value, and the display of the mode selection and the set setting value A digital display unit 23, a transmission / reception unit SS for transmitting and receiving wirelessly with the smart sensor 10, a relay RE for automatically turning on / off the power supply of lighting, and a microcontroller controlling and controlling the above. Smart switch 20 consisting of (MC); A plurality of power plug insertion sockets 31 for supplying power to electric appliances in the room, a selection button 32 for selecting settings and setting values in a constant / sleep mode, and displaying and setting mode selections. And a digital display unit 33 indicating the set value, a receiver unit SS1 for receiving a signal from the smart sensor 10, a relay RE for automatically turning on / off the power supply of the power plug, and the above. Smart outlet 30 is composed of a microcontroller (MC) for controlling; It collects and transmits and receives the network terminal 14 connected to the smart sensor 10 in each room of the entire building and transmits and receives the data to and from the smart sensor 10, and the network server 41 and the network server 41 connected to the external Internet communication network. The display unit 43 detects the data sent by the smart sensor 10 and converts it into data, and displays the signals sent by the smart switch 20 and the smart outlet 30 individually and collectively in real time, and an operation command of an administrator. Remote central server 40 consisting of a control unit 44 for transmitting the; Remote monitoring controller 50 for transmitting and receiving information by connecting to the central server 42 through the Internet communication network wirelessly from the outside, and directly transmitting the operation command to the central server 42, The smart sensor 10, smart switch 20, smart outlet 30 is installed in each room of the building so as to communicate with each other wirelessly, the smart sensor 10 of each room has its own network terminal ( 14) is connected to the network server 41 to connect the smart sensor 10 of the entire building to the central server 42 for managing the operation, the central server 42 is an external Internet communication network through the network server 41 It provides a smart power saving system of the building, characterized in that the remote monitoring and control from the outside by the remote monitoring controller 50 by connecting to.
