Description

  The present invention relates to an elevator-based evacuation system that performs an evacuation operation of an elevator between a predetermined escape floor and an evacuation floor in order to evacuate people in a building when a fire occurs.

  In a conventional elevator control device, when a fire occurs, an elevator evacuation operation method is created based on the location of the fire / smoke generation (see, for example, Patent Document 1).

  By the way, in a building where entry and exit to each floor is restricted by the security system, intrusion from the emergency stairs to the corridor or living room of each floor is usually restricted by an electric lock or the like. Such restriction by an electric lock or the like is released by a personal identification number, a fingerprint, an ID card, a radio wave tag, or the like. Moreover, when the invasion to the emergency staircase from the hallway or the living room is restricted, a method of releasing this restriction in conjunction with the detection of the fire by the fire detector has been proposed (for example, see Patent Document 2).

  Moreover, in the conventional elevator control device for an earthquake, when the earthquake occurs, the traveling car is stopped at the nearest floor, and the electric lock of the door located on the passenger's evacuation route is automatically unlocked ( For example, see Patent Document 3).

The elevator evacuation management unit 11 receives an input from the fire occurrence / fire place determination unit 7 (step S1) and determines whether or not a fire has occurred (step S2). If no fire has occurred, the next input from the fire occurrence / fire location determination unit 7 is accepted. That is, the elevator evacuation management unit 11 repeatedly receives input from the fire occurrence / fire location determination unit 7 and continuously monitors the presence or absence of fire until a fire occurrence is detected.

  When the occurrence of a fire is detected, the elevator evacuation management unit 11 outputs a command for carrying out the fire control operation to the elevator operation control unit 8 and the electric locks on the corridor 4 side of all the doors 3 with electric locks. Is output to the electric lock control unit 9 (step S3). As a result, all the cars are temporarily returned to a predetermined return floor (for example, the nearest floor), and all the electric lock doors 3 are allowed to be opened from the corridor 4 side, so that the movement from the corridor 4 to the emergency staircase 2 is allowed. Is possible.

  Thereafter, the elevator evacuation management unit 11 determines whether or not a preset execution condition for the evacuation operation is cleared. Here, as an execution condition of the evacuation operation, whether the fire occurrence place is an escape floor (step S4), whether the fire occurrence place is a hoistway of the elevator 1 (step S5), or evacuation is not completed (step S4) S6) is determined.

  Here, the execution conditions of the evacuation operation are not limited to these. For example, the fire occurrence location is not the elevator landing, the fire occurrence location is not the elevator machine room, and the fire occurrence location is adjacent to the elevator landing. You may add conditions, such as not being a division.

  When all the conditions for the evacuation operation are satisfied, the elevator evacuation management unit 11 outputs an evacuation operation command to the elevator operation control unit 8 (step S7), and the emergency stairs 2 side of the door 3 with the electric lock on the escape floor A command for unlocking the electric lock is output to the electric lock control unit 9 (step S8), and an evacuation guidance display command during the evacuation operation is output to the evacuation guidance control unit 10 (step S9).

  Thereby, the evacuation operation of the elevator 1 is implemented. In addition, opening of the electric lock door 3 on the escape floor from the side of the emergency stairs 2 is allowed, and a person can freely move from the emergency stairs 2 to the corridor 4 on the escape floor. Furthermore, an arrow and a message for guiding a person in the building along the evacuation route when the evacuation operation is performed are displayed on the evacuation guidance display device 5.

  Further, during the evacuation operation, the elevator evacuation management unit 11 repeatedly determines whether or not all the evacuation operation conditions are satisfied.

  On the other hand, when at least one of the execution conditions for the evacuation operation is not satisfied from the beginning, or when at least one of the execution conditions is not satisfied during the evacuation operation, the elevator evacuation management unit 11 outputs an evacuation operation end command. (Step S10), a command to lock the electric lock on the emergency stairway 2 side of the door 3 with the electric lock on the escape floor is output to the electric lock control unit 9 (Step S11), and an evacuation operation guidance command at the end of the evacuation operation is issued It outputs to the evacuation guidance control part 10 (step S12), and a process is complete | finished.

  Thus, the evacuation operation is not performed or terminated, and the opening of the door 3 with the electric lock on the escape floor from the emergency staircase 2 side is prohibited. The evacuation guidance display device 5 displays a message indicating that evacuation using the elevator 1 is impossible, a message prompting evacuation using the emergency staircase 2, and the like.
