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 method, and more particularly to an elevator remote monitoring method during seismic control.

[0002]

2. Description of the Related Art A conventional device is disclosed in Japanese Patent Laid-Open No. 62-21128.
As described in Japanese Patent No. 0, when an earthquake detector detects an earthquake of a predetermined value or more and the elevator is put into a dormant state, a signal indicating that the elevator has stopped due to the earthquake is sent to a monitoring center that monitors the elevator via a communication line. There has been proposed an elevator remote monitoring method in which an elevator that has been put into a dormant state by an earthquake is remotely returned from a monitoring center while being notified.

[0003]

In the above prior art, when a disaster occurs over a wide area, especially an earthquake occurs, a large number of elevators are put in a dormant state by the earthquake detection. Therefore, the monitoring center monitors the elevators. However, there is a problem that it is not possible for the limited number of monitoring personnel who are in charge to perform the reception processing and restoration of the hibernation state. In addition, since the frequency of use of communication lines becomes extremely high in each region, the communication lines are concentrated and terminal devices cannot connect to the communication lines. There was a problem that I didn't know if it was in a state.

An object of the present invention is to provide a method of remotely monitoring an elevator that can efficiently monitor an elevator that is in a dormant state due to an earthquake.

[0005]

[Means for Solving the Problems] In order to achieve the above object, a signal is output when seismic sensing installed in a building constructed in an area composed of a plurality of areas detects a seismic intensity higher than a predetermined level, A monitor that puts the elevator installed in the building in a dormant state, and remotely monitors the occurrence of an elevator abnormality by connecting a terminal device that inputs an abnormality signal of the elevator and the terminal device via a communication line. In an elevator remote monitoring method for notifying a center, at least one representative building is selected in advance from buildings in the area, and the signal of the seismic detector of the selected building is output to the terminal device. However, the occurrence of an earthquake having a seismic intensity equal to or higher than the predetermined value is notified to the monitoring center.

[0006]

According to the present invention, a signal for putting the elevator of the seismic detector of at least one building representing a region in a dormant state is output to a terminal device, and a signal is sent to a monitoring center via a communication line so that the elevator is in a dormant state. Can be managed by region,
The monitoring center can efficiently manage the occurrence of elevator hibernation even in the event of an earthquake where communication lines are frequently used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

In the figure, a monitoring center 1 is a communication device 1
a, a control device 1b, a storage device 1c, a display device 1d, and a storage device 1e, and the monitoring center 1 monitors the area 2 where the abnormality of all elevators is monitored via the communication line T and the communication station NTT 2A, Divide into 4 areas of 2B, 2C, 2D, select the buildings representing each area, and
If the representative building in the A district (for example, the Ichibancho district of Sendai City) is, for example, Igarashi Building A, an earthquake detector (not shown) is installed in Igarashi Building A, and this earthquake detector (not shown) is installed. ) Has a contact AW that detects an earthquake and opens when a predetermined seismic intensity of, for example, seismic intensity 4 is reached, and puts the elevator in a dormant state. The contact AW is composed of an input device A1a, a control device A1b, and a communication device A1c. , Terminal device A1
The contact point AW of the seismic detector (not shown) connected to the input device A1a means that the elevator housed in 2A, Ichibancho district, Sendai city, was put to rest by all earthquakes. Is. The communication device A1c of the terminal device A1 is connected to the communication device 1a of the monitoring center 1 via the communication line T and the communication station NTT.

Next, the operation will be described.

Assuming now that an earthquake of seismic intensity 4 has occurred in the area 2 monitored by the monitoring center 1, the earthquake detector (not shown) of the Igarashi Building A in 2A, Ichibancho, Sendai City operates. Then, the contact AW opens. Then, the elevator is in the dormant state, and at the same time, the input device A1a outputs a signal of the elevator dormant state to the control device A1b by opening the contact AW, and the control device A1 activates the communication device A1c.
A1c-T-NTT-
It is transmitted to the communication device 1a of the monitoring center 1 through the communication line of T-1a. The communication device 1a, which has received the signal indicating that the elevator has stopped operating from the Igarashi Building A, analyzes the content of the received signal according to the command from the control device 1b, and displays the data stored in the storage device 1c on the display device 1d. Shows the displayed content. At the same time, the recording device 1e prints the history, for example, “Pause due to earthquake occurrence in Ichibancho district, Sendai City, 11:35, April 4, 1991”.

Similarly, the other areas 2B to 2D also send an elevator resting state generation signal to the monitoring center 1.

[0012]

According to the present invention, a signal for putting the elevator of the seismic detector of at least one building representing the area in a dormant state is output to the terminal device, and the monitoring center is notified via the communication line. Since the dormant state of the elevator can be managed for each region, the monitoring center can efficiently manage the dormant state of the elevator even in the event of an earthquake where communication lines are frequently used.
