The descending call button 93 is a button for calling the car 2 going to the lower floor to the platform 6. The landing intercom 94 can transmit voice into the car 2 via the control device 10 and can receive voice in the car 2. The landing intercom 94 has, for example, a receiver, and enables the user in the landing 6 to talk with the user in the passenger car 2 by raising the receiver.

  The elevator alarm system 100 according to the present embodiment includes an emergency call button 86, a landing speaker 91, and a control device 10. The control device 10 according to the present embodiment controls the elevator 1 in normal operation as described above, and controls the car operation panel 8 and the landing operation panel 9 when the emergency call button 86 is pressed. As shown in FIG. 7, the control device 10 includes an abnormal elevator identification unit 13, an elevator information storage unit 14, an announcement selection unit 15, an announcement storage unit 16, a first transmission unit 17, and a second transmission unit 18. . When the emergency call button 86 in the car 2 is pressed in an emergency, an emergency call signal is output from the car operation panel 8 to which the emergency call button 86 is pressed toward the control device 10. The emergency call signal is input and stored in the abnormal elevator identification unit 13 of the control device 10.

  For example, the emergency call signal is set separately for the three elevators 1. That is, the emergency call signal when the emergency call button 86 of the elevator 1 located on the leftmost side when viewed from the landing 6 among the three elevators 1 shown in FIG. 1 and the emergency call button of the elevator 1 located in the center are displayed. The emergency call signal when 86 is pressed is different from the emergency call signal when the emergency call button 86 of the elevator 1 located on the rightmost side is pressed. In the following description, among the three elevators 1 shown in FIG. 1, the leftmost elevator 1 when viewed from the landing 6 is described as a first elevator, the central elevator 1 is described as a second elevator, The elevator 1 located on the right side is described as a third elevator.

  The elevator information storage unit 14 stores an emergency call signal database in which three elevators 1 and three emergency call signals are associated with each other. The abnormal elevator identification unit 13 has the emergency call button 86 of any elevator 1 out of the plurality of elevators 1 based on the input emergency call signal and the emergency call signal database stored in the elevator information storage unit 14. Identify And the abnormal elevator specific | specification part 13 outputs the information of the elevator 1 by which the emergency call button 86 was pushed to the announcement selection part 15 as a signal. Information on the elevator 1 whose emergency call button 86 has been pressed is input and stored in the announcement selection unit 15.

  The announcement storage unit 16 stores a plurality of announcements as voice information. In the present embodiment, the announcement storage unit 16 stores three different announcements. The three announcements correspond to the three elevators 1, respectively. For example, the first announcement of the first of the three announcements is an announcement that “the passenger is confined in the elevator on the leftmost side” and corresponds to the first elevator. The second announcement of the second of the three announcements is an announcement that “passengers are confined in the central elevator toward” and corresponds to the second elevator. The third announcement of the third of the three announcements is an announcement that “the passenger is confined in the elevator on the rightmost side” and corresponds to the third elevator.

  The announcement storage unit 16 stores an announcement database in which the three elevators 1 and the three announcements are associated with each other. The announcement selection unit 15 makes an announcement corresponding to the elevator 1 for which the emergency call button 86 has been pressed based on the information on the elevator 1 for which the emergency call button 86 has been pressed and the announcement database stored in the announcement storage unit 16. select. When the emergency call button 86 of the first elevator is pressed, the announcement selection unit 15 makes an announcement (first announcement) corresponding to the first elevator that “the passenger is confined to the leftmost elevator”. select. When the emergency call button 86 of the second elevator has been pressed, the announcement selection unit 15 selects the announcement (second announcement) corresponding to the second elevator that “passengers are confined to the central elevator”. To do. When the emergency call button 86 of the third elevator is pressed, the announcement selecting unit 15 makes an announcement (third announcement) corresponding to the third elevator that “the passenger is confined in the rightmost elevator toward the right”. select. And the announcement selection part 15 outputs the selected announcement to the 1st transmission part 17 and the 2nd transmission part 18 as audio | voice information.

  The first transmission unit 17 transmits the voice information input from the announcement selection unit 15 to the remote monitoring center 200. The remote monitoring center 200 that has received the voice information from the first transmission unit 17 can broadcast the announcement selected by the announcement selection unit 15 into the remote monitoring center 200 using a speaker or the like provided. Thereby, the staff in the remote monitoring center 200 can recognize which elevator 1 among the plurality of elevators 1 has an abnormality.

  The second transmission unit 18 transmits the voice information input from the announcement selection unit 15 to the landing operation panel 9. The hall operating panel 9 that has received the voice information from the second transmitter 18 can broadcast the announcement selected by the announcement selector 15 to the hall 6 by the hall speaker 91. As a result, the user at the landing 6 can recognize which of the plurality of elevators 1 is abnormal.

  FIG. 8 is a flowchart for explaining an example of the operation of the elevator alarm system according to the present embodiment. In the following description, the case where the emergency call button 86 of the first elevator is pressed will be described as an example. For example, the control device 10 constantly monitors the car operation panel 8 and can detect that the emergency call button 86 has been pressed. When the emergency call button 86 is not pressed, the control device 10 continues to monitor the car operation panel 8 (No in step S1). When the emergency call button 86 of the first elevator is pressed, the car operation panel 8 of the first elevator transmits an emergency call signal to the control device 10 (step S1, Yes).

  Next, the control apparatus 10 which received the emergency call signal specifies the 1st elevator by which the emergency call button 86 was pushed among the some elevators 1 by the abnormal elevator specific | specification part 13 (step S2). And the control apparatus 10 outputs the information of the 1st elevator in which the emergency call button 86 was pushed from the abnormal elevator specific | specification part 13 to the announcement selection part 15 as a signal.

  Next, the control device 10 selects the announcement that “the passenger is trapped in the leftmost elevator” corresponding to the first elevator by the announcement selection unit 15 (step S3). And the control apparatus 10 outputs the audio | voice information which is the selected announcement from the announcement selection part 15 to the 1st transmission part 17 and the 2nd transmission part 18. FIG.

  Next, the control device 10 starts broadcasting the announcement at the remote monitoring center 200 and the landing 6 by using the first transmitter 17 and the second transmitter 18 (step S4). At the remote monitoring center 200 and the landing 6, an announcement that “passengers are trapped in the leftmost elevator” is broadcast.

  The control device 10 can determine whether there is a response from the remote monitoring center 200. For example, the control device 10 determines whether or not there is a response from the remote monitoring center 200 by monitoring the operation of a handset provided in the remote monitoring center 200. When there is a response from the remote monitoring center 200 (step S5, Yes), the control device 10 ends the announcement broadcast at the remote monitoring center 200 and the landing 6 (step S6). Thereafter, the current situation is transmitted from the user in the first elevator to the remote monitoring center 200, and a contact is made from the remote monitoring center 200 to rescue the user trapped in the elevator management company or the like (step S7). .

  On the other hand, the control device 10 can determine whether or not there is a response from the landing 6. For example, the control device 10 determines whether there is a response from the landing 6 by monitoring the operation of the landing intercom 94 provided in the landing 6. When there is no response from the remote monitoring center 200 (step S5, No), it is determined whether there is a response from the landing 6 or not. When there is no response from the landing 6 (step S8, No), the control device 10 continues to determine whether there is a response from the remote monitoring center 200 (step S5). When there is a response from the landing 6 (step S8, Yes), the control device 10 ends the announcement broadcast at the remote monitoring center 200 and the landing 6 (step S9). Thereafter, the current situation is transmitted from the user in the first elevator to the user at the landing 6 via the landing intercom 94, the car speaker 84 and the microphone 85 of the car operating panel 8. Then, the current situation is transmitted from the user at the landing 6 to the remote monitoring center 200 (step S10). Next, the remote monitoring center 200 is contacted to rescue the user locked in the elevator management company or the like (step S7).

  As described above, the elevator alarm system 100 according to the present embodiment includes the control device 10 that is provided in a building including a plurality of elevators 1 and that stores a plurality of different announcements. When the emergency call button 86 is pressed, the control device 10 can broadcast from the hall speaker 91 an announcement corresponding to the elevator 1 from which the emergency call button 86 is pressed. As a result, when a user confined in the car 2 due to an emergency stop or the like presses the emergency call button 86, an announcement corresponding to the elevator 1 that has made an emergency stop is broadcast to the landing 6. For this reason, the elevator warning system 100 can make the user at the landing 6 recognize by voice that the confinement has occurred in the elevator 1. In addition to this, the elevator warning system 100 can allow the user at the landing 6 to recognize the elevator 1 among the plurality of elevators 1 by voice. Therefore, the elevator warning system 100 can shorten the time required from when the emergency call button 86 is pressed until the situation is transmitted to the remote monitoring center 200 or the like. Therefore, even if the elevator warning system 100 has a plurality of elevators 1 provided at the landing 6, the time required for rescue of the confined user can be shortened.

  Further, the elevator warning system 100 informs which elevator 1 of the plurality of elevators 1 is locked in by voice. Thereby, the warning system 100 of an elevator can transmit the situation of the elevator 1 to a blind user at the landing 6.

  In the elevator warning system 100 according to the present embodiment, the number of announcements is the same as the number of elevators 1. The announcement broadcast from the landing speaker 91 when the emergency call button 86 of one elevator 1 (for example, the first elevator) among the plurality of elevators is pressed is another elevator 1 (for example, the plurality of elevators 1). This is different from the announcement broadcast from the landing speaker 91 when the emergency call button 86 of the second elevator) is pressed. Thereby, the warning system 100 of the elevator can make the user in the landing 6 easily recognize in which elevator 1 of the plurality of elevators 1 the user is confined.

  Further, the elevator warning system 100 according to the present embodiment includes a landing intercom 94 at the landing 6 that can talk to a user in the car 2. As a result, the user at the landing 6 can make a call with the user confined in the elevator 1 after recognizing which one of the plurality of elevators 1 is confined to the elevator 1. For this reason, the user in the landing 6 can grasp the situation more accurately. Therefore, even if the elevator warning system 100 has a plurality of elevators 1 provided at the landing 6, the time required for rescue of the confined user can be further shortened.

  Note that the number of elevators 1 provided at the landing 6 is not necessarily three as described above, and may be two, or four or more. Further, the number of announcements stored in the announcement storage unit 16 of the control device 10 is preferably equal to or greater than the number of elevators 1 provided at the landing 6.

  The announcements corresponding to the elevators 1 are not limited to those described above, but are announcements that can tell the passengers at the landing 6 which of the elevators 1 is abnormal. I just need it. In other words, the announcement only needs to include a word indicating which of the plurality of elevators 1 is abnormal. For example, the announcement corresponding to the first elevator may be an announcement that “passengers are trapped in the first elevator”. However, in order to make it easier for the user at the landing 6 to grasp the elevator 1 where the confinement has occurred, the announcement directly indicates the position of the elevator 1 where the abnormality has occurred as viewed from the landing 6. It is preferable that the wording shown in is included. Further, the announcement may include a word indicating at which position in the height direction in the hoistway 7 the elevator 1 in which an abnormality has occurred. For example, an announcement may be made that “passengers are trapped in elevator 1; elevator 1 is stopped between the second and third floors”. In addition, in order to improve convenience for visually impaired users, the announcement may include a word indicating the elevator 1 during normal operation in addition to the wording indicating the elevator 1 in which an abnormality has occurred. For example, an announcement may be made that “passengers are trapped in elevator 1; elevators 1 and 2 are operating as usual”.

  Moreover, the control apparatus 10 may have separately the announcement for broadcasting to the remote monitoring center 200, and the announcement for broadcasting to the platform 6. For example, when the emergency call button 86 of the first elevator is pressed, the announcement to broadcast to the remote monitoring center 200 is an announcement that “passengers are trapped in the elevator 1” and The announcement for broadcasting may be an announcement that “the passenger is confined in the leftmost elevator”. The remote monitoring center 200 can grasp the elevator 1 in which confinement has occurred even if the announcement including the word indicating the position is not broadcasted directly.

  Further, the elevator warning system 100 may be provided with a display light at the landing 6 that is turned on when the emergency call button 86 is pressed. As a result, the elevator warning system 100 can allow the user at the landing 6 to recognize the elevator 1 among the plurality of elevators 1 through both visual and auditory senses. For example, the announcement in the case where the elevator warning system 100 includes an indicator lamp may be an announcement that “the passenger is confined in the elevator whose red lamp is lit”. By doing in this way, the user in the landing 6 can more easily grasp the elevator 1 in which confinement has occurred.

  Moreover, the one control apparatus 10 does not necessarily need to control the movement of the some elevator 1 like this embodiment. For example, each elevator 1 may be provided with a control device for controlling movement, and the control device 10 may be provided as a general control device that controls these control devices in an integrated manner. Further, the control device that controls the car operation panel 8 and the landing operation panel 9 when the emergency call button 86 is pressed may be provided separately from the control device that controls the elevator 1 in the normal operation.
