Automatic fire extinguishing system accompanied by PLC and secondary communication

The present invention relates to an automatic fire extinguishing system, and more particularly, transmit to the power line installed in groups of a fire signal detected by the fire sensor connected to the (Power Line Communication) PLC to the main communication means, or is the primary means of communication PLC as a precaution, not operation status capable of transmitting the operation command to the secondary communication to means to operate at the same time to the adjacent fire-extinguishing system disruption of the main control unit and the main communications means, further comprising a wireless communication means, such as ZigBee as wired and wireless It relates to the automatic fire extinguishing system. In the present invention, the automatic fire extinguishing system, data detected a fire sensing unit fire situation in which operation is provided by the boom in the building of for this purpose in the automatic fire extinguishing system for processing to automatically transfer, fire detection sensor, a power line communication unit, is attached to a ZigBee, a controller, and having a battery fire detection module and the fire detection module, in communication with the fire detection module and the automatic fire extinguisher is driven is controlled by the controller, which handles the external operation command management program for managing a controller the traffic control is provided, and the control unit comprises a terminal on which the administrator can issue a command to receive the emergency signal from the control portion to send the traffic control from the outside.
