Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator remote monitoring system capable of monitoring the status of an elevator even at a remote place using a public line.

[0002]

2. Description of the Related Art FIG. 3 is a configuration diagram showing a configuration of a conventional elevator remote monitoring system.

In FIG. 3, 1 is an elevator control device for controlling an elevator, 2 is an elevator monitoring device for monitoring the status of the elevator and transmitting according to the status, 3 is a monitoring center for centrally monitoring the status of the elevator remotely, Reference numeral 4 denotes a monitoring terminal provided in the monitoring center 3, and reference numeral 5 denotes a public line connecting the elevator monitoring device 2 and the monitoring terminal 4. Note that a general telephone line is used as the public line 5.

Next, the operation of the conventional elevator remote monitoring system having the above configuration will be described.

[0005] When the elevator control device 1 detects a failure or abnormality of the elevator, the elevator control device 1 transmits a signal from the elevator monitoring device 2 to the monitoring center 3 via the public line 5. And
The monitoring terminal 4 receives information such as a failure or an abnormality from the elevator monitoring device 2. This information is notified by the monitoring terminal 4 and the attendant responds.

When the status of the elevator is checked at the monitoring center 3, a signal is transmitted from the monitoring terminal 4 to the elevator monitoring device 2 via the public line 5. Then, the elevator monitoring device 2 transmits the information input from the elevator control device 1 to the monitoring terminal 4. This information is notified by the monitoring terminal 4 and the status of the elevator is confirmed in the monitoring center 3.

[0007]

SUMMARY OF THE INVENTION In the prior art,
Each time information is exchanged between the elevator monitoring device and the monitoring center, a connection to a public line must be established.

In such an elevator remote monitoring system, when a wide-area disaster or the like occurs, the public line becomes congested, the elevator monitoring device cannot be connected to the monitoring center, and the monitoring center cannot respond quickly. There is.

As a method of solving the above problem, a method of using a dedicated line instead of a general telephone line as a public line is conceivable, but the operation cost becomes expensive.

[0010] The present invention has been made to solve such a problem, and even when a wide-area disaster or the like occurs, information is reliably exchanged between the elevator monitoring device and the monitoring center, and monitoring is performed. It is an object of the present invention to provide a remote monitoring system for an elevator that can respond quickly at a center and has a low operation cost.

[0011]

SUMMARY OF THE INVENTION The present invention is directed to an elevator control device for controlling an elevator, an elevator monitoring device for monitoring the status of an elevator and transmitting the status according to the status, and concentrating the status of the elevator. A monitoring center for remote monitoring by
In an elevator remote monitoring system comprising a monitoring terminal provided at the monitoring center and a public line connecting the elevator monitoring device and the monitoring terminal, the status of the elevator is grasped by the public line. A signal channel for exchanging necessary information and the like, and an information channel for exchanging various kinds of information such as details of an elevator state, a sound, and a picture in a car.

The signal channels are always connected,
The information channel is connected and disconnected as needed.

The public line uses ISDN which is a digital communication line.

The signal channel is an ISDN D.
Channel, and the information channel uses the ISDN B channel.

The exchange of information on the signal channel uses packet communication.

[0016]

FIG. 1 is a block diagram showing the configuration of an elevator remote monitoring system according to an embodiment of the present invention.

In FIG. 1, the same reference numerals and symbols as those of the above-described conventional example indicate the same or corresponding components as those of the above-described conventional example, and perform the same or corresponding operations.

In FIG. 1, reference numeral 6 denotes an elevator monitoring device 2
And a public line connecting the monitoring terminal 4. The public line 6 is an ISDN which is a digital communication line.

Next, the operation of the elevator remote monitoring system according to one embodiment of the present invention having the above configuration will be described.

FIG. 2 is an operation diagram showing the operation of the elevator remote monitoring system according to one embodiment of the present invention.

In FIG. 2, (a) to (c) show the passage of time.

The exchange of information between the elevator monitoring device 2 and the monitoring terminal 4 is performed on a signal channel and an information channel provided on the public line 6.

The signal channel uses the ISDN D channel, and the information channel uses the ISDN B channel.

The signal channel uses packet communication.

In FIG. 2A, the elevator monitoring device 2 and the monitoring terminal 4 are always connected by a signal channel, and the status of the elevator is constantly monitored by the monitoring center 3.

In FIG. 2B, when a failure or abnormality of the elevator is detected, the information is transmitted to the monitoring center 3 via a signal channel, and the monitoring center 3 determines that further exchange of information is necessary. Means that the elevator monitoring device 2 and the monitoring terminal 4 are connected by an information channel,
Various information such as a detailed state of an elevator, a sound, and an image in a car, which cannot be sufficiently handled by the signal channel, is exchanged.

In FIG. 2C, when the exchange of information by the information channel between the elevator monitoring device 2 and the monitoring terminal 4 is completed, the information channel is disconnected.

The above shows only a part of the embodiment, and the present invention is not limited to the embodiment.

[0029]

As described above, according to the present invention, the elevator monitoring device and the monitoring terminal are always connected by the signal channel, and the status of the elevator is constantly monitored in the monitoring center. In addition, information channels are connected / disconnected as necessary, and data communication is performed according to the amount and quality of information to be transmitted. Therefore, even when a wide-area disaster or the like occurs, information can be reliably exchanged between the elevator monitoring device and the monitoring center, and a quick response can be made at the monitoring center. Even if the connection of the information channel cannot be established, since the minimum necessary information is transmitted only through the signal channel, it is possible to take some measures at the monitoring center.

Also, by using ISDN which is a digital communication line for the public line, using the D channel of ISDN for the signal channel and the B channel of ISDN for the information channel, high quality communication according to the characteristics of the public line. Can be realized.

Also, by using packet communication for the signal channel, the amount of information exchanged between the elevator monitoring device and the monitoring terminal is charged, so that even if the connection is always made, the operation cost can be reduced. it can.
