The present invention relates to a control box of a net-separation server network (distribution board, emergency generator, network device, CCTV, broadcasting device, auto-controller), a remote control system, and a controlling method thereof. A net-separation server controls at least one control unit, and is integrated with an inside of a housing so that a remote control unit connected to an external network controls the control unit through an external network main board in a state that an internal network main board connected to an internal network and an external network main board are connected between a backup router physically separated from the internal network and a VPN. The net-separation server is switched to an ON contact of a network switch, an ON contact of an external network switch, and an OFF contact of an internal network switch so that the server transmits the power supply presence data from a converter to a remote control unit through a transceiver of the control unit. The remote control unit controls the control unit through the external network main board and includes a display unit. When the remote control unit is at the ON contact of a network switch, the ON contact of an external network switch, and the OFF contact of an internal network switch, a network communications state between the external network main board and the remote control unit is displayed on the display unit of the remote control unit. |
