  The tsunami evacuation operation switch 514 generates a tsunami evacuation signal and transmits it to the elevator control panel 8 when operated by an administrator who has recognized the tsunami warning. When operated from the ON state to the OFF state, a tsunami evacuation release signal is generated and transmitted to the elevator control panel 8.

  An earthquake detector 7 is installed at the lower part of the hoistway 2. The earthquake detector 7 outputs an earthquake detection signal when an earthquake is detected.

  An elevator control panel 8 is installed at the upper part of the hoistway 2 and is connected to the car 5 by a tail cord (not shown) and is connected to the hoisting machine 3 and the earthquake detector 7 by a signal line.

  The elevator control panel 8 is connected to an external weather information system 10 via a network 9 and receives a tsunami warning issued from the weather information system 10.

  A detailed configuration of the elevator control panel 8 is shown in FIG. The elevator control panel 8 includes an operation control unit 81, a detection signal reception unit 82, a diagnosis unit 83, a tsunami warning reception unit 84, and a warning output unit 85.

  The operation control unit 81 determines the current position of the car 5, the destination floor button group 511 of the in-car operation panel 51, the door opening button 512, the door closing button 513, the operation status of the tsunami evacuation operation switch 514, the elevator control panel 8 Based on the information sent from the detection signal receiving unit 82, the diagnosis unit 83, and the tsunami warning receiving unit 84, normal operation, seismic control operation, or tsunami evacuation control operation is performed.

  The detection signal receiving unit 82 receives the earthquake detection signal output from the earthquake detector 7 and sends it to the operation control unit 81.

  The diagnosis unit 83 diagnoses whether or not the elevator can be automatically restored based on the operation state of the operation control unit 81 after the occurrence of the earthquake.

  The tsunami warning receiving unit 84 receives a tsunami warning issued from the external weather information system 10.

  The warning output unit 85 outputs the tsunami warning received by the tsunami warning receiving unit 84 with a display or voice to notify the manager or the residents.

<Operation of Elevator System According to One Embodiment>
Next, operation | movement of the elevator system 1 by this embodiment is demonstrated with reference to the flowchart of FIG.

  First, when an earthquake is detected by the earthquake detector 7 during normal operation by the operation control unit 81 of the elevator control panel 8, an earthquake detection signal is output and acquired by the detection signal receiving unit 82 ( S1).

  When the earthquake detection signal is acquired by the detection signal receiving unit 82 (“YES” in S1), the operation control unit 81 executes an earthquake control operation (S2).

  Here, as the control operation at the time of earthquake, an operation is performed in which the car 5 on which the user is boarding is stopped at the nearest floor and opened. The user gets off at the opened floor and uses the evacuation stairs to evacuate to the first floor where there is an entrance to the outside. The elevator stopped at the nearest floor is then in a dormant state.

  Next, the diagnosis unit 83 diagnoses whether or not the operation of the elevator stopped due to the occurrence of the earthquake can be restored in advance by the automatic restoration function provided in the operation control unit 81 (S3).

  When the diagnosis unit 83 diagnoses that the automatic restoration of the elevator operation is possible (“YES” in S3), the normal operation is resumed after a predetermined automatic restoration operation (S4).

  After normal operation is resumed by automatic recovery, if a tsunami warning is issued from the weather information system 10 within a predetermined time (for example, several hours), it is received by the tsunami warning receiver 84 (“YES” in S5) The data is output from the output unit 85 by display or sound. The tsunami warning received by the tsunami warning receiving unit 84 is also sent to the operation control unit 81.

  When the tsunami warning is acquired, the operation control unit 81 moves the car 5 to the first floor set as the reference floor in advance, and opens the door after landing (S6).

  Thereafter, when the administrator who has recognized the output tsunami warning operates the tsunami evacuation operation switch 514 to the ON state, a tsunami evacuation signal is generated and transmitted to the elevator control panel 8.

  In the elevator control panel 8, when the operation control unit 81 receives a tsunami evacuation signal ("YES" in S7), the tsunami evacuation control operation is started. The tsunami evacuation control operation executed by the operation control unit 81 will be described.

  First, when the tsunami evacuation control operation is started, a call with the top floor as the destination floor is registered (S8).

  Next, when the person to be evacuated enters the car 5 that is open on the standard floor and the door close button 513 is operated for a long time (“YES” in S9), the car 5 is closed and the destination floor is reached. The vehicle is driven at a low speed to the top floor, and after landing, the door is opened (S10). By driving at a low speed, safety can be achieved for wheelchair users and elderly people.

  The evacuation target person can get off the top floor and move to the rooftop using evacuation stairs or the like to take evacuation action against the tsunami.

  Next, it is determined whether or not there is an evacuation target person on the reference floor. If it is determined that there is an evacuation target person (“YES” in S11), a call with the reference floor as the destination floor is registered (S12).

  Here, whether or not there is a person to be evacuated on the reference floor is determined, for example, by analyzing an image of a surveillance camera in which the elevator hall on the reference floor is installed.

  Next, when an evacuation guide or the like gets into the car 5 and the door close button 513 is pressed for a long time (“YES” in S13), the car 5 is closed and moves to the reference floor which is the destination floor. After the landing, the door is opened (S14).

  Thereafter, until it is determined that there is no evacuation target person on the reference floor, the processes in steps S9 to S14 are repeated, and automatic operation is performed so that the car 5 circulates between the reference floor and the top floor. .

  After all the evacuated persons have moved to the top floor by elevator and are no longer at the reference floor (“NO” in S11), when the weather information system 10 notifies the release of the tsunami warning, the notification is received by the tsunami warning. Received by the unit 84 and output from the alarm output unit 85 by display or voice.

  When the manager recognizes the tsunami warning release notification output from the warning output unit 85 and the tsunami evacuation operation switch 514 is turned off, a tsunami evacuation release signal is generated and transmitted to the elevator control panel 8. The

  In the elevator control panel 8, when the tsunami evacuation release signal is received by the operation control unit 81 (“YES” in S15), the car 5 is stopped at the top floor (S16) and the tsunami evacuation control is performed. Operation is terminated and normal operation is resumed.

  In step S3, when it is determined that the operation of the elevator stopped due to the occurrence of the earthquake cannot be recovered by the automatic recovery function ("NO" in S3), the operation is stopped (S17).

  According to the above-described embodiment, when a tsunami warning is issued after an earthquake occurs, the evacuation target in the building is surely determined by performing a tsunami evacuation control operation based on a specific operation by an administrator or the like. In addition, control operation can be performed to evacuate from the tsunami safely.

  In the above-described embodiment, when the tsunami warning received by the tsunami warning receiver 84 is a large tsunami warning, the tsunami evacuation is performed when the large tsunami warning is received regardless of the operation state of the tsunami evacuation operation switch 514. The time control operation may be started.

  Although the embodiment of the present invention has been described, this embodiment is presented as an example and is not intended to limit the scope of the invention. The novel embodiment can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention.
