In this case, the above-described voice announcement may be repeated at intervals of several seconds, for example.

  When the call attribute of the call related to the planned stoppage floor is not a backup call (NO in S504), or after notifying that the elevator 60 is going to the specific public floor by a speaker in the car (S505) When the fourth predetermined time has elapsed, the elevator control device 40 performs the door closing operation of the car door (S506), and returns to step S501.

3. Operation The operation of the present embodiment will be described. First, the problem will be described in detail. On the lobby floor, users are concentrated during work hours. Therefore, in an elevator system in which landing destination floor registration devices are installed on all floors, a larger number of landing destination floor registration devices are installed on the lobby floor than on other floors. For example, when six elevators exist in one group, about 4 to 6 landing destination floor registration devices are installed. On the other hand, on general floors other than the lobby floor, there is not much concentration of users, so only about one or two landing destination floor registration devices are installed. Therefore, on the general floor, the probability that all the landing destination floor registration devices break down is higher than that on the lobby floor. If all the landing destination floor registration devices on one floor break down, the user of that floor cannot register the destination floor and cannot move to another floor.

  In order to cope with such a problem, in this embodiment, the landing destination floor registration device 30 of each floor transmits a heartbeat signal every first predetermined time C. Further, the group management control device 10 does not receive a heartbeat signal from all the landing destination floor registration devices 30 of one floor for a second predetermined time T longer than the first predetermined time C, that is, When all the landing destination floor registration devices 30 of one floor break down, a backup call with the floor as the departure floor and the lobby floor as the destination floor is automatically generated every third predetermined time R, and the backup call The elevator 60 is operated so as to respond. Therefore, even when all the landing destination floor registration devices 30 on one floor break down, the user can use the elevator from the floor to the lobby floor. And it can move to another floor from a lobby floor by using the hall destination floor registration apparatus 30 of a lobby floor as needed.

(Embodiment 2)
The second embodiment will be described with reference to the drawings.

  FIG. 9 is a block diagram showing the configuration of the elevator system according to the second embodiment.

  The elevator system according to the second embodiment is connected to a building security system. The security system includes a plurality of security gates 70 and a security server 100 arranged on the lobby floor of the building. The security server 100 is configured using a computer having a control unit and a storage unit. The security gate 70 includes a flapper (not shown), a card reader 71, and an LCD (Liquid Crystal Display) 72, and controls the user's entry into a specific area in the building including the elevator hall. The security system includes a card reader 36 in addition to the landing destination floor registration device 30. The card readers 71 and 36 read the card ID from the ID card held by the user and transmit it to the security server 100. In the storage unit of the security server 100, information on the destination floor and the departure floor is stored in association with the card ID.

  When the security server 100 receives the card ID from the card reader 71 of the security gate 70, the security server 100 determines whether the card ID is a legitimate one stored in the storage unit, and if it is legitimate, associates it with the card ID. The information on the destination floor and departure floor being read is read out. Then, the security server 100 transmits the read destination floor and departure floor information and the gate identification information of the security gate 70 having the used card reader 71 to the group management control device 10. When the group management control device 10 receives the destination floor and departure floor information and the gate identification information of the security gate 70 from the security server 100, it is assumed that the destination floor call has occurred, and the destination floor call is sent to a plurality of elevators 60. Assign to either. Then, the group management control device 10 transmits and displays information such as the assigned machine name on the LCD 72 of the security gate 70 corresponding to the gate identification information. On the other hand, when the card ID is not valid, the security server 100 operates the flapper of the security gate 70 to restrict the user from entering the specific area.

  When the security server 100 receives the card ID from the card reader 36 provided in the hall destination floor registration device 30, the security server 100 determines whether the card ID is a legitimate one stored in the storage unit. Information indicating that a legitimate ID card is held and reader identification information for identifying the used card reader 36 are transmitted to the group management control device 10. The group management control device 10 receives the destination floor assignment request signal from the landing destination floor registration device 30 and receives information indicating that a legitimate ID card is held from the security server 100 and the card reader 36 used. When the reader identification information for identification is received, the destination floor call is assigned to one of the plurality of elevators 60, assuming that the destination floor call has occurred. Then, the group management control device 10 transmits information such as the assigned car name to the landing destination floor registration device 30 corresponding to the reader identification information.

  In the group management control device 10 and the landing destination floor registration device 30 of the elevator system connected to such a security system, by performing processing based on the flowcharts of FIGS. An effect is obtained.

  Here, when a failure as described above occurs, for example, if one elevator is set to stop operation at each floor, the elevator can be used even from the floor where all the landing destination floor registration devices have failed. . However, in a building provided with a security system as described above, it is difficult to apply each floor stop operation because of the relationship with the tenant because there is a possibility that a person other than the related person enters the floor when the stop operation is performed on each floor. According to the present embodiment, since the floor stop operation is not performed, the above problem does not occur.

(Other embodiments)

  In the first and second embodiments, an elevator system having a plurality of elevators 60 is illustrated. However, the present invention can also be applied to an elevator system having only one elevator 60, and the same operations and effects as in the first and second embodiments can be obtained.

  In the second embodiment, the example in which the security gate 70 is provided on the lobby floor has been described. However, the security gate 70 may be provided on a plurality of floors (a plurality of public floors where general users can enter). is there. In this case, the heartbeat signal may also be transmitted to the group management control device 10 on the LCD 72 of the security gate 70 as with the landing destination floor registration device 30. If the heartbeat signal is not received from all the landing destination floor registration devices 30 and the LCD 72 of the floor, a third backup call is made with the floor as the departure floor and the other public floor as the destination floor. The elevator 60 may be operated so as to be automatically generated every time R and to respond to the backup call. When the LCD 72 of the security gate 70 breaks down, the user can enter the elevator hall on the floor, but cannot recognize the assigned car on the LCD 72, and there is a possibility that the use of the elevator may be hindered. However, by adopting a configuration in which the LCD 72 also transmits a heartbeat signal, the user can move to another public floor and use the elevator as in the first and second embodiments. That is, the same operations and effects as those of the first and second embodiments are exhibited.
