A network management system for an automatic opening and closing device of an exit and a management method using the same are provided to reduce the installation cost of equipment and to facilitate maintenance and repair works by checking the opening and closing states of exits and visitors in real time by detecting an RFID(Radio Frequency Identification) tag signal through a multi-tap antenna. In a network management system interlocking with opening and closing devices(20) of exits(1,2,3) to manage the exits of a building through the network, at least one emergency detector(10,11,12) has a sensor detecting and converting physical information and the change rate of information into an electric signal, and modulates the electric signal into a wire or wireless signal and transmits the wire or wireless signal. The opening and closing device is installed at the exit to operate the exit into an opening or locking mode by power supplied from the outside, and equipped with a fixed RFID tag(210) storing ID(Identification) information of the exit. An entrance card(30) has a portable RFID tag(310) discriminating ID number information of users and inputs the opening and closing of the exit through non-contact communication. Main controllers(40,41,42) open the entrance card by the electric signal sent from the emergency detector or the entrance card. The main controller embeds an RFID reader detecting the fixed RFID tag of the opening and closing device or the portable RFID tag of the entrance card and transmits and receives ID number information and the collected RFID tags through a wireless antenna(410). A central controller manages information about the opening and closing situations of the exits by collecting the RFID tags transmitted through the antenna and controls the operation of the total opening and closing devices.
