(Embodiment 2)
In the first embodiment, the intercom call device provided on the ceiling of the car surely collects the call voice of the passenger in the car. However, when there are many passengers in the car or when the elevator is installed near a downtown area, it is possible that the original sound is drowned out by these noises. Therefore, in preparation for such a case, a case will be described below in which a noise cancellation circuit is provided in the elevator remote monitoring device to eliminate such noise. In the following description, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  FIG. 2 is a diagram showing an example of the overall configuration of a system including an elevator remote monitoring device according to the present embodiment. As shown in FIG. 2, in this example, in addition to the components shown in the first embodiment, sound is collected from a microphone (not shown) provided in the intercom call device 8 inside the elevator remote monitoring device 16. A noise cancellation circuit 20 is provided for canceling a voice signal in a predetermined frequency band for the call voice and canceling ambient noise.

In this case, the intercom communication device can be easily installed without considering the wiring such as the illumination described above.

  Furthermore, in the first and second embodiments described above, the case where the interphone communication device 8 is installed in the center of the ceiling (or floor surface) of the car 2 has been described as an example. In the case where a dedicated car door (not shown) and a car door 3 dedicated to the exit are provided, it is considered that passengers of the car 2 often gather on the car door 3 side dedicated to the exit. In the case of a passenger car having a different form, as shown in FIG. 4, an interphone communication device 811 may be provided on the floor near the car door 3 dedicated to the exit. In this case, the interphone call device can be installed at an appropriate position close to the position of the passenger in the car and without being interrupted by the passenger.

  FIG. 4 shows an example in which the interphone communication device is installed on the floor surface on the side of the car door dedicated to the exit, but it is of course possible to provide it on the ceiling side. As shown in FIG. 4, not only when a plurality of car doors are provided as described above, but also when there is one car door as shown in FIGS. 1 to 3 (the doorway is common). It is also possible to install an interphone communication device on the ceiling or floor surface of the car door side.

  The present invention is not limited to the above-described embodiments, and includes various modifications. For example, the above-described embodiments have been described in detail for easy understanding of the present invention, and are not necessarily limited to those having all the configurations described. Further, a part of the configuration of one embodiment can be replaced with the configuration of another embodiment, the configuration of another embodiment can be added to the configuration of one embodiment, or the configuration of each embodiment can be changed. It is possible to add, delete, and replace other configurations for the part. For example, if the noise is even louder, the interphone call device is installed on both the ceiling side and the floor side. In that case, the ceiling side interphone call device is provided in the center, and the floor side interphone call device is on the car door side. It is possible to freely combine the interphone communication device arrangement methods, such as providing in (or vice versa).
