  As shown in FIG. 4, in step S401, it is determined whether the evacuation operation by the elevator is possible. If the evacuation operation is possible, the process proceeds to step S402, and if the evacuation operation by the elevator is interrupted, the evacuation operation is terminated. . Specific means for determining whether or not evacuation operation is possible will be described later. In step S402, all the cars 2 are moved to the escape floor. At this time, the evacuation driving guidance function 1 may make an announcement or display indicating that the elevator can be evacuated, or may perform an operation such as blinking the landing lamp 4 on the escape floor. Since the initial position of the car 2 at the end of step S402 is after the completion of the fire control operation, it exists on the evacuation floor, and the car 2 is unattended. Further, when the evacuation operation by the elevator has already been started, the car 2 is either on the escape floor or on the evacuation floor and the car 2 is unmanned. In step S403, it is determined whether or not the hall call button 5 is pressed on the escape floor and the hall is called. If the hall is called, the process proceeds to step S404. If there is no hall call, the process proceeds to step S401. Transition. In step S404, the same operation as in step S401 is performed, and it is determined whether evacuation operation by an elevator is possible. At this time, when the evacuation operation by the elevator is possible, the process proceeds to step S405, and when the evacuation operation by the elevator is interrupted, the evacuation operation is terminated. In step S405, the door of the car 2 is opened on the escape floor and the evacuees are boarded. At this time, an announcement or a display indicating that the user can board the vehicle by the evacuation driving guidance function 1 may be made in the elevator hall or the car 2, or the escape lamp 4 may be turned on. In step S406, the same operation as in step S401 is performed to determine whether or not the evacuation operation by the elevator is possible. This determination corresponds to a change in the fire situation until the evacuees get on the car 2 and the door is closed. At this time, when the evacuation operation by the elevator is possible, the process proceeds to step S407, and when the evacuation operation by the elevator is interrupted, the evacuation operation is terminated. In step S407, the door of the car 2 is closed and the process proceeds to step S408. In step S408, the car 2 is caused to travel from the escape floor to the evacuation floor, and the process proceeds to step S409. When there are a plurality of escape floors, the vehicle travels to the next escape floor and performs the operation process of steps S405 to S408. In step S409, after arriving at the evacuation floor, the door of the car 2 is opened and the refugee is alighted, and the process proceeds to step S410. In step S410, the same operation as in step S401 is performed to determine whether or not the evacuation operation by the elevator is possible. This determination corresponds to a change in the fire situation between the arrival of the car 2 at the evacuation floor and the completion of the evacuee's getting off. At this time, if the evacuation operation by the elevator is possible, the process proceeds to step S402, and if the evacuation operation by the elevator is interrupted, the evacuation operation is terminated.

The evacuation operation availability determination shown in FIG. 5 is the evacuation operation availability determination in step S401, step S404, step S406, and step S410 of FIG.

  As shown in FIG. 5, in step S501, it is determined whether or not a fire has occurred on the escape floor based on information from the fire detection state detection unit 333. If no fire has occurred, the process proceeds to step S502. If a fire has occurred, the process proceeds to step S508. In step S502, it is determined whether or not a fire has occurred under the first floor of the escape floor based on information from the fire detection state detection unit 333. If no fire has occurred, the process proceeds to step S503, and the fire is detected. If it has occurred, the process proceeds to step S508. In step S503, it is determined whether or not a fire has occurred in the elevator hall or adjacent section on each floor based on the information from the fire detection state detection unit 333. If no fire has occurred, the process proceeds to step S504. If it has occurred, the process proceeds to step S508. In step S504, it is determined whether a fire has occurred in the elevator shaft or the machine room based on information from the fire detection state detection unit 333. If no fire has occurred, the process proceeds to step S505, where a fire has occurred. If yes, the process proceeds to step S508. In step S505, the elevator pit or car 2 depends on the state of the water immersion sensor provided on the elevator pit or car 2 or in the machine room obtained from each of the vehicle control functions 31-1 to 31-N or the group management control function 32. If the machine room or the machine room is not submerged, the process proceeds to step S506. If the machine room is submerged, the process proceeds to step S508. In the event of a fire, water discharged during fire fighting activities by sprinklers and fire brigades may flow into the elevator shaft, and as a result, the elevator may stop due to electric leakage, etc. Become. Thus, the inundation sensor is provided at a predetermined location of the building as one of the disaster detectors. In step S506, it is determined whether an evacuation operation end command is output from the evacuation operation end command input unit 334. If the evacuation operation end command is not output, the process proceeds to step S507, and the evacuation operation end command is output. If yes, the process proceeds to step S508. In step S507, it is determined from the result of step S506 that the evacuation operation is possible, and the process proceeds to step S509.

  In step S509, in the evacuation operation stop prediction unit 335, based on the data of the fireproof time data storage unit 336 and the fire detection history storage unit 337, any location on the escape floor, directly below the escape floor, the elevator hall of each floor A time when a fire has progressed to any of the adjacent section, the elevator shaft, and the machine room and the evacuation operation by the elevator is stopped, that is, the evacuation operation stop time is predicted, and the process proceeds to step S510. In step S510, it is determined whether or not an evacuation operation stop notice is necessary based on the time predicted by the evacuation operation stop prediction unit 335, and if an evacuation operation stop notice is necessary, the process proceeds to step S511. If an advance notice is not required, the process proceeds to step S512. In step S511, an evacuation driving stop notice guidance command by an elevator is output to the evacuation driving guidance function control unit 332, and an evacuation operation is permitted by informing the evacuee from the evacuation driving guidance function control unit 332 via the evacuation driving guidance function 1. End the decision. In step S512, an evacuation operation continuation guidance command is output to the evacuation operation guidance function control unit 332, and the evacuation operation permission determination is terminated.

  In step S508, it is determined that the evacuation operation by the elevator is stopped, and the process proceeds to step S513. In step S513, the evacuation operation stop guidance command by the elevator is output to the evacuation operation guidance function control unit 332, and the evacuation operation permission determination is terminated.

Next, the process for predicting the stop of the evacuation operation shown in step S509 of FIG. 5 will be described. The evacuation operation stop time T _p predicted in step S509 in FIG. 5 is the minimum value of the fire progress time to the adjacent section of the elevator hall, the elevator shaft, the elevator machine room, the escape floor, and the floor immediately below the escape floor. The fire progress time is predicted with respect to the progress of the fire in the plane direction of the building and the progress of the fire in the vertical direction, but both can be predicted by the same method. Only the prediction of the progress time will be described.

  FIG. 6 is a plan view of a fire occurrence floor according to an embodiment of the present invention. As shown in FIG. 6, the plan view is composed of rooms 7-1 to 7-5, passages 8-1 to 8-3, fire doors 9-1 to 9-3, an elevator hall 10, and an elevator shaft 11. Yes. The rooms 7-1 to 7-5 are independent fire prevention sections. The fire progress time to each section is the sum of the fire resistance times of the sections that pass through the shortest route from the place where the fire occurred to the place where the progress of the fire is to be predicted, and is calculated by Equation (1).

Here, T _p (X) is the predicted fire progress time to the section X, T ₀ (x _s ) is the fire detection time at the fire occurrence place x _s , and R (x) is the design value of the fire resistance time of the section x is there. Further, “pass” is a set of sections in the shortest path from the fire occurrence place to X.

  For example, assume that a fire has occurred in the room 1 as shown in FIG. The fire progress prediction time at this time is calculated | required by Formula (2) and Formula (3).

Therefore, the fire progress prediction time T _p on the fire floor in FIG. 6 is expressed by Equation (4).

Next, the process for determining whether or not the evacuation driving stop notice is required, which is shown in step S510 of FIG. 5, will be described. Assuming that the current time is T _n , the fire progress prediction time is T _p , and the predetermined margin time is T _m , the evacuation operation stop notice is given when T _n ≧ T _p −T _m , otherwise Does not give notice of stopping evacuation. Here, T _m ≧ 0.

  In the present embodiment, each vehicle control function 31, the group management control function 32, and the evacuation operation control function 33 are installed in the elevator control device, but these functions may be installed as independent devices. Moreover, although only the evacuation driving stop notice is performed based on the evacuation driving stop prediction, the evacuation operation by the elevator may be stopped as well as the notice. In that case, the evacuation operation may be stopped by the evacuation operation control unit 331 after a preset time from the notice.

  Based on the above, it is possible to predict the fire progress prediction time, which is the predicted evacuation operation stop time, based on the detection time by the fire detector and the fireproof design value of the building, and to make an evacuation operation stop notification based on the prediction. Therefore, when evacuation by an elevator is stopped, it is possible to smoothly switch to another evacuation means.
