[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an elevator notification device, and in particular, the present invention relates to a notification device for an elevator, and in particular, a notification device that uses an intercom from inside the car and monitors using a television camera inside the car based on a command from a monitoring center. The present invention relates to an elevator notification device configured to be able to selectively receive notifications.

[Prior Art] The inside of an elevator car becomes a kind of closed room while the elevator is in operation, so there is a possibility that various illegal acts and crimes may be committed. When a situation occurs, it is necessary to immediately understand the situation externally.

In order to fully understand the status of such abnormal situations, it was recommended in 1983 that in addition to an intercom operated by the passenger to communicate with the outside, a television camera for surveillance should be placed inside the car. -48669 Publication and Utility Model Publication No. 1787/1987
This is proposed in Publication No. 68.

In these Japanese Patent Publication No. 58-48669,
There is an internal monitoring system in the elevator that has an antenna in the hoistway and sends the video signal captured by a TV camera placed inside the elevator to the monitoring room via a coaxial cable, where the image is displayed on a receiver or recorded on a VTR. Disclosed.

In addition, in Utility Model Application Publication No. 61-178768, the image taken by a television camera inside the first car is switched to be displayed on either a monitor TV installed on a panel in the hall or a monitor TV in a monitoring room. An elevator monitoring device is disclosed.

As described above, according to the proposed monitoring device, it is possible to monitor the inside of the first car using a monitor television provided in the monitoring room or the hall, and to grasp the state of an abnormal situation.

[Problems to be Solved by the Invention] When the technology related to the above-mentioned proposal is introduced, it is possible to monitor the inside of the car using a monitor TV in the monitoring room, compared to the case where only voice notifications are made using the conventional intercom. It is possible to more completely understand the state of an abnormal situation.

However, in a monitoring center that remotely monitors building equipment, it is not possible to monitor images captured by a television camera installed inside a passenger car on a monitor. For this reason, when the building monitoring room manager is not present, the monitoring center can communicate directly with the users inside the car through the intercom inside the car, but the situation inside the car cannot be monitored by the TV camera. It cannot be grasped visually through images.

In order to enable the monitoring center to directly monitor images captured by a television camera installed inside the passenger car on a monitor, a new communication line must be installed to transmit image data to the monitoring center using image transmission technology. It is conceivable to display images on the computer, but adding additional communication lines poses a problem in terms of cost.

The present invention has been made in view of the current situation of grasping the condition inside an elevator car as described above.

The purpose of this system is to create an elevator notification system that can monitor the inside of a car by directly displaying images captured by a TV camera installed inside the car on a monitor TV at the monitoring center, without having to install additional communication lines. Our goal is to provide the following.
