Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an elevator emergency contact device.

[0002]

2. Description of the Related Art Generally, an emergency call device for an elevator operates a terminal device having a telephone function provided in a machine room or the like by operating a call button on the call device by a passenger in a car to operate a telephone line. It is configured to automatically dial the monitoring center via. The operator of the monitoring center responding to the automatic dial talks with the passenger in the car and takes measures to rescue the passenger from the car.

However, since it is delayed through the operator of the monitoring center, in order to promptly rescue the passengers who are trapped in the car due to the abnormality of the elevator, Japanese Patent Laid-Open No. Hei 3 (1999) -311
As described in Japanese Patent No. 296898, there is a device that directly notifies a maintenance worker who is working in the area closest to the building where the emergency communication device has been activated, to send a dispatch instruction.

[0004]

The above-mentioned prior art is a building in which a plurality of elevators are delivered. In a building where one elevator is being maintained by a maintenance worker, an abnormality occurs in another elevator and passengers are trapped. If a confined passenger operates the emergency call button, the monitoring center will be called once and the maintenance center will select the appropriate maintenance personnel, so maintenance personnel working in the same building will be called. There was a problem of spending a lot of time.

It is an object of the present invention to provide an elevator emergency contact device that enables prompt rescue of a passenger trapped during maintenance work by any of a plurality of elevators.

[0006]

In order to achieve the above object, the present invention provides a plurality of units each having a maintenance operation switch operated during maintenance operation in each car, an emergency call button and a communication device. An emergency contact device for an elevator, comprising: an elevator; and a terminal device that connects each of the communication devices and a monitoring center that remotely monitors an abnormality of a plurality of elevators so that a call can be made via a communication line. The device includes a maintenance machine detection device that detects that the maintenance operation switch has been operated, an emergency call machine detection device that detects that the emergency call button has been operated, and an emergency call machine detection device and a maintenance machine detection device. And a notification selection device that is connected to the device and that selects a notification destination of the elevator for which the emergency call button is operated.

[0007]

With this configuration, when passengers are trapped in a car in another elevator and the emergency call button is operated during maintenance work on the elevator, the notification destination selection device causes the maintenance device detection device to operate. Since the maintenance personnel who are working are informed to the elevator that is being detected by the fact that a confinement accident has occurred, passengers can be rescued immediately.

[0008]

An embodiment of the present invention will be described below with reference to the drawings.

In the figure, a terminal device 1 installed in a building monitors an abnormality of control devices 4, 5 of a plurality of elevators 2, 3 and is connected to a monitoring center 7 via a communication line 6. There is.

In the terminal device 1, an abnormality detection device 1a and
Communication device 1b, machine number detection device 1c, and notification selection device 1
d is provided, and the machine number detection device 1c is composed of an emergency call machine detection device 1ca and a maintenance machine detection device 1cb, and the emergency call machine detection device 1ca and the maintenance machine detection device 1cb are connected to the notification selection device 1d. . The notification selection device 1d is connected to the communication device 1b, the control devices 4, 5, and the telephones 2a, 3a installed in the elevators 2, 3, respectively. In addition, the emergency call machine detection device 1ca
Emergency call buttons 2b, 3 installed in elevators 2, 3
b respectively. In addition, the machine detection device 1c
b is connected to maintenance operation switches 2c and 3c installed in the elevators 2 and 3, respectively. Further, the control devices 4 and 5 are respectively connected to the respective floor display devices, car display devices, and alarm devices 2d and 3d such as a car buzzer installed in the elevators 2 and 3, respectively.

On the other hand, in the monitoring center 7 connected to the terminal device 1 through the communication line 6, a reception device 7a which responds to dialing signals and control commands from the terminal device 1 and informs the operator by display printing. And a handset 7b for calling the passengers in the car.

Next, while the maintenance staff is working on the elevator 3,
Emergency call button 2 when a trap accident occurred in elevator 2.
A case where b is operated will be described.

An emergency call button 2 for passengers in the elevator 2 car
When c is operated, the emergency call machine detection device 1ca detects that the elevator 2 is an emergency call (step S).
1). Further, since the elevator 3 is working and the maintenance operation switch 3b is turned on, the maintenance machine detection device 1c
b detects that the elevator 3 is under maintenance (step S2). Further, the notification selection device 1d, which receives the signals from the emergency call machine detection device 1ca and the maintenance machine detection device 1cb, notifies the control device 5 to the notification device 3d of the elevator 3, for example, each floor display device and in-car display device. Flashing,
A signal for ringing the car buzzer is output (step S3). Here, the maintenance staff who hears the alarm device 3d, for example, a buzzer above the car, recognizes that the passengers are trapped in another elevator installed in the building, that is, the elevator 2, and rescues the passengers. Once the maintenance operation switch 2c of the elevator 2 is turned on during the rescue operation, the maintenance machine detection device 1cb detects it (step S4), and the control device 5 is operated via the notification selection device 1d.
A signal for stopping notification to the notification device 3d is output (step S5).

In this embodiment, a building in which two elevators are delivered has been described, but the same applies to the case where there are many elevators.

[0015]

According to the present invention, when passengers are trapped in a car in another elevator and an emergency call button is operated during maintenance work on an elevator, the notification destination selection device causes the maintenance machine detection device to operate. Passengers can be rescued as soon as the maintenance personnel who are working are informed that the detected elevator is trapped in the accident.
