Description

  The present invention relates to a communication line check in an elevator remote monitoring system.

  In general, an elevator remote monitoring system monitors a running state of an elevator and issues a line check for every predetermined period (for example, once / day), and a plurality of the monitoring devices and communication lines. And a monitoring center that sends back a received signal to the monitoring device in response to receiving the line check notification.

  In response to the reception of the received signal by the monitoring device, it is checked that the communication line is normal.

By the way, since the one-day / day line check increases the burden of communication costs, conventionally, if another type of report, such as an abnormal report, is received at the monitoring center, that day Has been proposed that the line check with the monitoring device is not performed and the communication cost is reduced (see Patent Document 1).
JP 2000-099866 A (paragraph numbers 0025 and 0026)

  However, even in the prior art, if other types of notifications, such as abnormal notifications, are not received at the monitoring center, the one-day / day line check must be performed, thereby reducing communication costs. There was an inconvenience that was not enough.

  The present invention has been made in view of this inconvenience, and an object of the present invention is to provide an elevator remote monitoring system capable of greatly reducing the communication cost in the line check.

  In order to achieve the above object, the present invention according to claim 1 is connected to a monitoring device that monitors the running state of the elevator and issues a line check for every predetermined period, and a plurality of the monitoring devices connected via a communication line. In a remote monitoring system for an elevator comprising a monitoring center that sends back a reception signal to the monitoring device in response to receiving the line check notification, a line from the monitoring device to the monitoring center every fixed period It is detected that the check alert has been normally received for a predetermined period, and in response to this detection, the received signal is not transmitted even if the line check alert is received in the second period that is longer than the predetermined period. A line check confirmation means for processing is provided.

  According to the first aspect of the present invention, as described above, since the line check confirmation means is provided, it is possible to reduce the number of times of transmission of the received signal to the monitoring apparatus confirmed to be normal, and to check the line accordingly. It is possible to achieve a reduction in communication costs.

  According to a second aspect of the present invention, in addition to the first aspect of the invention, the line check confirmation means can normally receive the line check notification for each predetermined period after the change to the second period. In response to the absence, the processing is performed so that the second period is returned to the original predetermined period, so that it is possible to prevent a decrease in abnormality detection accuracy in the line check.

  The present invention can provide an elevator remote monitoring system capable of greatly reducing the communication cost in the line check.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  1 and 2 show an embodiment of the present invention.

  However, FIG. 1 is a block diagram showing the overall configuration of an elevator remote monitoring system showing an embodiment of the present invention, and FIG. 2 is a flowchart showing the operation of the line check confirmation means which is an embodiment of the present invention.

  First, a basic configuration of an elevator remote monitoring system according to the present embodiment will be described with reference to FIG.

  In FIG. 1, an elevator remote monitoring system according to the present invention includes a monitoring device 4 that monitors a running state of an elevator and issues a line check every predetermined period (for example, once / day), and a plurality of the monitoring devices 4. The monitoring center 1 is connected via a communication line (public line network) 2 and sends back a reception signal to the monitoring device 4 in response to receiving the line check notification. Further, it is assumed that the elevator is installed in the building 3.

  Further, the monitoring center 1 detects that the line check notification has been normally received from the monitoring device 4 every predetermined period (for example, once / day) for a predetermined period (for example, one month), and in response to this detection. In a second period (for example, once / week) that is longer than the predetermined period (for example, once / day), a line check confirmation is processed so that the received signal is not transmitted even if the line check notification is received. Means 1a are provided.

  Hereinafter, the operation of the line check confirmation means which is the main part of the present invention will be described with reference to FIGS.

  As shown in FIG. 2, the line check confirming means 1a is convinced that the line check notification is received from the monitoring device 4 at the monitoring center 1 (S1).

  If it is confirmed that the reception of the line check notification has been normally performed for a predetermined period (for example, one month) (S2), the received signal that has received the line check notification is monitored for normality. The sending back to the apparatus 4 is stopped for a second period (for example, one week) (S3). Further, if it is not possible to confirm that the operation has been normally performed for a predetermined period (for example, one month), the reception signal is sent to the monitoring device 4 every time according to the line check notification for every predetermined period (for example, once / day) as usual. Since the data is sent back, it is possible to prevent a decrease in abnormality detection accuracy in the line check (S2).

  In addition, after the transmission of the received signal is stopped in the second period (for example, one week), the line check notification for each predetermined period (for example, once / day) cannot be normally received by the line check confirmation means 1a. However, since the received signal is sent back to the monitoring device 4 every time in response to the line check notification every predetermined period (for example, once / day), the deterioration of the abnormality detection accuracy in the line check is prevented. (S5).

  And if it can be confirmed that the operation is normally performed for a predetermined period (for example, one month) (S6), the sending back to the monitoring device 4 confirmed to be normal is stopped for the second period (for example, one week). (S3).

  According to the present invention, since the line check confirmation unit 1a is provided as described above, it is possible to reduce the number of transmissions of the received signal to the monitoring apparatus 4 that has been confirmed to be normal, and accordingly the communication cost in the line check. Can be achieved.

  Furthermore, in addition to the above-mentioned invention, the present invention is further characterized in that the line check confirmation means 1a checks the line every predetermined period (for example, once / day) after changing to the second period (for example, once / week). In response to failure to receive the notification normally, the second period (for example, once / week) is configured to process to return to the original fixed period (for example, once / day). It is possible to prevent a decrease in abnormality detection accuracy in the line check.

The block diagram which shows the whole structure of the remote monitoring system of the elevator which shows one Embodiment of this invention. The flowchart which shows operation | movement of the line check confirmation means which is one Embodiment of this invention.
