Further, when the general elevator operation control unit 8a determines that the stop floor of the general elevator car 5 is not the same floor as the emergency elevator car 15 when the first car doorway is in the door-closed state, the emergency elevator car The general elevator car 5 is dispatched to the 15th floor and the general elevator car 5 is put on the door-closing standby.

  Furthermore, when the general elevator operation control unit 8a determines that the general elevator car 5 is stopped on the same floor as the emergency elevator car 15 and the first car doorway is in a door-closed state, the stop floor It is determined whether or not the first hall operation button 19a is operated. Further, the general elevator operation control unit 8a stops the first of the stop floors when the general elevator car 5 is stopped on the same floor as the emergency elevator car 15 and the first car doorway is in the door-closed state. When the hall operation button 19a is operated, the first car door body 30 is opened.

  Next, the operation will be described. FIG. 4 is a flowchart showing an operation mode selection operation performed by the general elevator operation control unit 8a of FIG. Note that the operation shown in FIG. 4 is an operation when a fire detection sensor detects a fire in a building when the fire control setting is set manually or when the fire control setting is set automatically. It is.

  In the figure, when the fire control setting is set to manual setting or the fire control setting is set to automatic setting, if a fire in the building is detected by the fire detection sensor, the auxiliary execution setting is set to OFF. It is determined whether or not (step S1). At this time, if it is determined that the auxiliary execution setting is set to OFF, operation control in the fire control operation mode is started (step S2).

  On the other hand, if it is determined that the auxiliary execution setting is not set to OFF, it is determined whether or not the auxiliary execution setting is set to the first auxiliary operation mode execution setting (step S3). If it is determined that the primary auxiliary operation mode execution setting is set, operation control in the first auxiliary operation mode is started (step S4).

  On the other hand, when the auxiliary execution setting is not OFF setting and is not the first auxiliary operation mode execution setting, it is determined whether or not the auxiliary execution setting is set to the second auxiliary operation mode execution setting (step S5). ). At this time, if it is determined that the auxiliary execution setting is set to the second auxiliary operation mode execution setting, the operation control in the second auxiliary operation mode is started (step S6). On the other hand, when the auxiliary execution setting is not the second auxiliary operation mode execution setting, it is confirmed again whether or not the auxiliary execution setting is set to the OFF setting or the first auxiliary operation mode execution setting. This operation mode selection operation is always performed even when operation control is performed in each operation mode. That is, when the auxiliary execution setting is switched during operation control in each operation mode, the operation control is switched at that time.

  Next, FIG. 5 is a flowchart showing in detail the fire control operation mode of FIG. In the figure, when the operation control in the fire control operation mode is started, it is determined whether or not the general elevator car 5 is stopped outside the evacuation floor (step S10). At this time, if it is determined that the general elevator car 5 is stopped outside the evacuation floor, the general elevator car 5 is returned to the evacuation floor (step S11). Next, when it is determined that the general elevator car 5 has been returned to the evacuation floor, the first car door body 30 is opened (step S12), and after the predetermined time, the first car door body. 30 is closed (step S13), and then the general elevator car 5 is put on standby at the evacuation floor (step S14).

  Next, FIG. 6 is a flowchart showing in detail the first auxiliary operation mode of FIG. In the figure, when the operation control in the first auxiliary operation mode is started, it is determined whether or not the general elevator car 5 is stopped outside the evacuation floor, and the general elevator car 5 is stopped outside the evacuation floor. If it is determined, the general elevator car 5 is returned to the evacuation floor. Next, if it is determined that the general elevator car 5 has been returned to the evacuation floor, the first car door body 30 is opened, and the general elevator car 5 is left on the evacuation floor as it is (step). S15).

  Next, FIG. 7 is a flowchart showing in detail the second auxiliary operation mode of FIG. In the figure, when the operation control in the secondary auxiliary operation mode is started, it is determined whether the general elevator car 5 is stopped outside the evacuation floor, and the general elevator car 5 is stopped outside the evacuation floor. If it is determined, the general elevator car 5 is returned to the evacuation floor.

  Next, when it is determined that the general elevator car 5 has been returned to the evacuation floor, it is determined whether or not the first car doorway is in an open state (step S16), and the first car doorway is the door. If it is determined that it is in the open state, it is determined whether or not the first door closing button 23c is operated (step S17). At this time, if it is determined that the first door closing button 23c is not operated, the general elevator car 5 is put on standby (step S18), and if it is determined that the first door closing button 23c is operated, After a predetermined time has elapsed from the operation, the first car door body 30 is closed (step S19).

  Next, if it is determined that the first car doorway is in the door-closed state, it is determined whether the stop floor of the general elevator car 5 is the same floor as the emergency elevator car 15 (step S20). At this time, if it is determined that the stop floor of the general elevator car 5 is different from the stop floor of the emergency elevator car 15, the general elevator car 5 is dispatched to the stop floor of the emergency elevator car 15 (step S21). At that floor, the general elevator car 5 is put on standby (step S22).

  Next, when it is determined that the stop floor of the general elevator car 5 is the same as the stop floor of the emergency elevator car 15, it is determined whether or not the first hall operation button 19a on that floor is operated ( Step S23). At this time, if it is determined that the first landing operation button 19a on the stop floor is not operated, the door-closing standby of the general elevator car 5 is maintained (step S24). At this time, when the emergency elevator car 15 is dispatched to another floor, the general elevator car 5 is dispatched following that. On the other hand, if it is determined that the first landing operation button 19a on the stop floor is operated while the general elevator car 5 is stopped on the same floor as the emergency elevator car 15, the stop floor of the emergency elevator car 15 is stopped. Thus, the first car door body 30 is opened (step S25).

  In such a general elevator control device 8, the operation mode of the general elevator car 5 performed by the general elevator operation control unit 8 a at the time of a fire in a building is the primary auxiliary that makes the general elevator car 5 stand by on the escape floor. Since it is possible to switch between the operation mode and the secondary auxiliary operation mode in which the general elevator car 5 follows the emergency elevator car 15, the equipment required for fire fighting activities is carried into the general elevator car 5 at the evacuation floor. In addition, the equipment carried into the general elevator car 5 at the destination of the fire brigade can be used. That is, not only the emergency elevator car 15 but also the general elevator car 5 can be used for fire fighting activities, the transportation capacity of equipment can be improved, and fire fighting activities can be assisted more efficiently.

  In addition, the general elevator operation control unit 8a, when the operation control in the second auxiliary operation mode, when the general elevator car 5 is stopped at the landing floor with the first car doorway being opened, Since the door closing start timing of the first car door main body 30 is delayed, the fire brigade in the general elevator car 5 operates the first door closing button 23c and then goes out of the general elevator car 5. That is, even if there is only one fireman, the first car door body 30 can be moved to the emergency elevator car 15 with a margin after the first car door body 30 is closed, and the convenience of the firefighters can be improved.

  Furthermore, the general elevator operation control unit 8a stops the general elevator car 5 on the floor where the emergency elevator car 15 is stopped during the operation control in the secondary auxiliary operation mode, and the general elevator car 5 is closed. While waiting, it is determined whether or not the first landing operation button 19a on the floor is operated, and when it is determined that the first landing operation button 19a is operated, the first car door body 30 is moved to the door. Because it is opened, the first car doorway can be kept closed until the firefighters confirm the surroundings. When the general elevator car 5 stops at the landing floor, smoke or hot air blows into the general elevator car 5 This can reduce the possibility of damage to the general elevator car 5 and equipment.

  In the first embodiment, only one general elevator control device 8 has been described, but the other general elevator control devices 8 also perform similar operation control. Fire control settings in a plurality (one group) of general elevator control devices 8 can be collectively set with one fire control switch 25. Further, the auxiliary execution setting in each general elevator control device 8 can be individually set by the auxiliary mode changeover switch 26 connected to each general elevator control device 8. Normally, the auxiliary mode changeover switch 26 is installed on the elevator monitoring panel in the building, but it may be installed on the elevator hall as a keyed switch.

  In the first embodiment, it has been described that a position detection switch or a pulse counter is used as the position detection device. However, the position detection device may be another device that emits information corresponding to the raising and lowering of the car.
