  • Patent number: 8839914
    Abstract: An elevator system capable of an efficient evacuation using an elevator in case of a fire, and capable of confirming an evacuee remaining status in a case that an evacuation operation using the elevator is discontinued. An evacuation-call response-order setting section sets a priority order of a response to an evacuation special call registered in an evacuation special call registration section, based on fire occurrence information received by a fire situation reception section. A responding floor is selected based on the priority order. The evacuation operation running section controls an operation of the elevator so as to direct a car to the responding floor selected in this manner. In a case that the evacuation operation availability determination section determines that the evacuation operation is not available, the evacuation operation terminating section causes an evacuation special call remaining floor display section to display a remaining evacuation special call registration floor.

  • Publication number: 20110108365
    Abstract: An evacuation supporting system which can provide elevators in a building for evacuation in event of a fire and can substantially reduce the burden required by the rescue at the site of the fire by providing, before the arrival of firemen at the building, the firemen with information on the evacuation condition of the weak and the condition of evacuation of those who are present in the building carried out by use of the elevators. In an ancillary room within the building, there is installed an evacuation detection device which is used by disaster preventing staff in a disaster prevention center within the building to check for persons who have escaped into the ancillary room. When a fire has been detected by a fire detector, the elevators in the building are provided for evacuation for those who are present in the building, and the input status of the evacuation detection device and the evacuation operation condition of the elevator are transmitted to an external computer environment.
