  • Patent number: 7262692
    Abstract: An emergency evacuation guiding system for guiding people to run away in a building system as an accident occurs comprises a detector system for detecting an accidents which is occurred in the building system; an informing system for informing people that an accident occurs; a receiving system for receiving wireless signals from the informing system so as to know the message about the occurring of an accident; a guiding system for guiding people to run away from an accident area to a safety place; the guiding system including the at least one transmitter of the informing system and at least one receiver of the receiving system. The guiding system guides people to run out of the accident area by using the strength of the received signal in the receiver. The receiving system including at least one wireless receiver for detecting the strengths of the signals transmitted from the transmitter to the receiver.

  • Publication number: 20070182539
    Abstract: An emergency area confinement and safety system includes a central control unit for integrating all the other units in the system. A detector unit for detecting accidents occurred in a building unit. An accident determination unit receives signals from the detectors and determining whether an accident has occurred. The accident determination unit has an accident determination logic unit for determining an accident being occurred; a contour setting unit for defining a contour as an unsafe area. The contour setting unit receives the signals from the accident determination unit to know which section has accident and then determines an unsafe area according to the detecting cells; and a guiding unit for guiding people to run away from the accident area to a safety area; and a display unit in the central control unit for displaying the states.
