ZIGBEE FIRE DEFENSE SYSTEM

摘要

PURPOSE: A fire defense system using a ZigBee communications is provided to prevent secondary damage after the fire diffusion by locally suppressing a fire. CONSTITUTION: An abnormality sign sensing unit(100) senses the temperature and the humidity of a fire detected region. A relay node unit(200) relays data transceiving between the fire symptom administration unit and a plurality of fire symptom sensing units. The fire symptom managing unit(300) compares sensed information with a threshold which is set according to each sensor. An operating signal is transmitted to a solid aerosol fire extinguisher.
