Radio disaster prevention system, radio relay node and wireless node disaster prevention

摘要

PPROBLEM TO BE SOLVED: To provide a radio disaster prevention node without assignment, capable of directly receiving even a radio signal from a sensor node assigned to a radio wave relay node, in order to improve communication reliability. PSOLUTION: A plurality of node IDs containing a radio type sensor assigned beforehand are registered to each of a radio wave repeater 14-1 and a repeater 12-1 for radio wave reception. When a transmission source ID of a received radio signal is matched with a registered node ID, the received radio signal is processed as an effective radio signal. When setting of a registration mode, a node ID registered at a relay control table 66 in the radio wave repeater 14-1 is transmitted to the repeater 12-1 for radio reception and registered additionally at a relay control table 74. Then, a radio signal received directly from a radio type fire sensor assigned to a radio wave relay node is processed as an effective radio signal. PCOPYRIGHT: (C)2011,JPO&INPIT
