Patent ID: 8793726

Claim:
An optical integration system for disaster emergency broadcasting communication comprising: sensor units sensing surrounding temperatures and strains and distributed throughout a building; a broadcast communication merging part multiplexing a broadcast signal received through a cable and satellite broadcast network and communication signal received through a communication network into optical signals having different wavelengths and transmitting a merged broadcast communication optical signal; receivers receiving the optical signal transmitted from the broadcast communication merging part, demultiplexing by wavelength, transmitting the separated broadcast signal and the communication signal to corresponding peripheral terminals, and transmitting information detected by the sensor units to the broadcast communication merging part; and a management server determining a disaster situation from the information detected by the sensor units and received from the receivers and the broadcast communication merging part and, if the disaster situation is determined, transmitting processing signals to the receivers through the broadcast communication merging part, wherein the management server transmits the signal to the respective guidance indicator lamps connected to the receivers distributed based on position information database (DB) having position information for the sensor units stored therein according to the determined disaster situation and transfers emergency guidance broadcast to the peripheral terminals, the receivers further include a wireless sensor node connected thereto to select one of a passive optical communication network, a WiFi mesh network, and a USN Ad-Hoc network according to the position information DB of the management server and intelligence type network forming information to reconstruct a wired/wireless network that can be recovered in the disaster situation for communication, and a mobile remote management server capable of communicating with the management server is configured to be remotely accessible to the wireless sensor node and to transmit the information to the receivers through the wireless sensor node.
