Abstract

Provided, on each floor of a building, are an elevator installation zone, in which an elevator is installed, a neighboring zone which neighbors the elevator installation zone, and is in communication with the elevator installation zone through a first communication port, and an external zone which is in communication with the neighboring zone through a second communication port different from the first communication port. The first communication port is opened and closed by a first fire door, and the second communication port is opened and closed by a second fire door. A fire evacuation support system manages an operation of the elevator based on information from a plurality of fire detectors provided on each floor when a fire occurs in the building. Further, the fire evacuation support system includes an evacuation operation command section in which implementation of an evacuation operation for transporting a person left in the building to an evacuation floor is allowed for the elevator when contamination due to the fire is avoided in both the elevator installation zone and the neighboring zone, and in which the implementation of the evacuation operation is stopped when at least anyone of the elevator installation zone and the neighboring zone is contaminated due to the fire.

Claims (6)

1. A fire evacuation support system for managing an operation of an elevator based on information from a plurality of fire detectors provided on each of a plurality of floors when a fire occurs in a building, the building including, on each of the plurality of floors, an elevator installation zone in which the elevator is installed, a neighboring zone neighboring the elevator installation zone, the neighboring zone being in communication with the elevator installation zone through a first communication port, and an external zone in communication with the neighboring zone through a second communication port different from the first communication port, the first communication port being opened and closed by a first fire door, and the second communication port being opened and closed by a second fire door, the fire evacuation support system comprising

an evacuation operation command section in which implementation of an evacuation operation for transporting a person left in the building to an evacuation floor is allowed for the elevator when contamination due to the fire is avoided in both the elevator installation zone and the neighboring zone, and in which the implementation of the evacuation operation is stopped when at least any one of the elevator installation zone and the neighboring zone is contaminated due to the fire.

2. A fire evacuation support system according to claim 1 , further comprising a fire door control section for controlling an operation of each of the first fire door and the second fire door based on the information from each of the fire detectors.

3. A fire evacuation support system according to claim 2 , wherein the fire door control section causes each of the first fire door and the second fire door provided on an operation target floor preset to correspond to a fire occurrence floor on which the fire detector has detected the contamination due to the fire, among the first fire doors and the second fire doors provided on the plurality of floors, to operate in conjunction with a detection of the fire by the fire detector on the fire occurrence floor to close each of the first communication port and the second communication port.

4. A fire door control device for controlling an operation of each of a first fire door for opening and closing a first communication port and a second fire door for opening and closing a second communication port different from the first communication port based on information from a plurality of fire detectors provided on each of a plurality of floors of a building when a fire occurs in the building including, on each of the plurality of floors, an elevator installation zone in which an elevator is installed, a neighboring zone neighboring the elevator installation zone, the neighboring zone being in communication with the elevator installation zone through the first communication port, and an external zone in communication with the neighboring zone through the second communication port,

wherein the fire door control device causes each of the first fire door and the second fire door provided on an operation target floor preset to correspond to a fire occurrence floor on which the fire detector has detected contamination due to the fire, among the first fire doors and the second fire doors provided on the plurality of floors, to operate in conjunction with a detection of the fire by the fire detector on the fire occurrence floor to close each of the first communication port and the second communication port.
