Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an earthquake remote monitoring system for an elevator, and more particularly, an earthquake remote monitoring system for an elevator capable of improving a communication state at the time of an earthquake and more quickly identifying an elevator in which an abnormality occurs due to the earthquake. Regarding the system.

[0002]

2. Description of the Related Art Conventionally, an earthquake detector is provided and a monitoring device for monitoring an elevator is provided, and when an earthquake occurs,
A remote monitoring system is used in which the elevator is stopped and controlled by the operation of the seismic detector, and the monitoring device notifies the monitoring device to a remote monitoring center.

By the way, an earthquake simultaneously occurs in a wide area, several thousand to several tens of thousands of earthquake detectors are activated, and a large number of monitoring devices simultaneously send reports to a monitoring center. For this reason, communication disconnection may occur in the lines and switches between each monitoring device and the monitoring center.In the monitoring center, which seismic detector operated during an earthquake caused an abnormality in the elevator. It takes time to figure out. In order to solve such a problem, a remote monitoring system has been proposed that improves the notification when an earthquake occurs.

For example, as a first conventional example, Japanese Patent Laid-Open No. 8-
Japanese Patent No. 298693 discloses a remote monitoring system that avoids communication congestion when an earthquake occurs. That is,
When the abnormality detector (earthquake detector) on the monitoring center side operates, a calling signal is sequentially transmitted to each building (monitoring device) to be monitored via a telephone line. When the seismic detector provided in each monitoring device operates, each monitoring device side stops the ringing sound on the monitoring center side after a lapse of a predetermined time, for example, 10 seconds, after capturing the calling signal on the monitoring center side. On the monitoring center side, when the ringing tone stops after 10 seconds, the seismic detector of the monitoring device operates to determine that the elevator stop control has been performed.

Thus, in this remote monitoring system,
The monitoring center sends a call signal to each monitoring device, and if the earthquake detector is operating on the monitoring device side, the ringing sound on the monitoring center side is stopped after a predetermined time. It is possible to judge whether the earthquake detector of the device has operated (abnormality).

As a second conventional example, Japanese Patent Laid-Open No. 9-3
Japanese Laid-Open Patent Publication No. 07656 discloses a line aggregation device that prevents the concentration of telephone lines when a plurality of monitoring devices simultaneously transmits to a receiving center (monitoring center) of a communication partner. This line aggregation device is connected between a plurality of monitoring devices and a reception center. The line aggregation device determines whether or not the signals have the same content when signals are simultaneously transmitted from a plurality of monitoring devices, and if they have the same content, aggregates them into one signal, Send the aggregated signal to the receiving center. For example, when an earthquake occurs, the plurality of monitoring devices transmit the earthquake abnormality information to the line aggregation device. When the line aggregation device receives the earthquake abnormality information for a predetermined number or more within a predetermined time, it transmits the earthquake abnormality information and the received number to the reception center. Therefore, it is possible to prevent the congestion of the line due to the occurrence of the earthquake.

[0007]

However, in the technique disclosed in the first conventional example, the monitoring center sequentially issues a calling signal to the monitoring device to investigate the abnormality.
Therefore, there is a possibility that the confirmation of the elevator where the abnormality is caused by the earthquake is postponed, and as a result, the problem that the restoration of the elevator stopped due to the earthquake is delayed occurs. There is also a problem that the entire damage situation cannot be grasped until the transmission of the calling signal to all the monitoring devices on the monitoring center side is completed.

Also, with the technique disclosed in the second conventional example, the adverse effect of simultaneous notification of the monitoring device can be prevented, but the line aggregation device collects the earthquake abnormality information into one signal in the order of reception. Therefore, there is a problem that it is difficult to identify which monitoring device is transmitting the abnormality and in which area the damage is great.

Therefore, the present invention has been made to solve the above problems, and prevents the congestion of the line at the time of the occurrence of an earthquake, and investigates the monitoring device in which the earthquake detector operates from the severely damaged area. It is an object of the present invention to provide an earthquake-corresponding remote monitoring system for an elevator that can more quickly identify an elevator in which an abnormality has occurred due to an earthquake.

[0010]

An elevator earthquake remote monitoring system according to the present invention includes an earthquake detector, and is connected to a plurality of monitoring devices for monitoring an elevator and a plurality of monitoring devices via lines. An elevator seismic remote monitoring system consisting of a remote monitoring center, and multiple monitoring devices are provided in the monitoring center when the geographically adjacent monitoring devices are grouped and the earthquake detector is activated.

Further, when the monitoring center of the elevator earthquake remote monitoring system of the present invention receives the initial warning from the sampled monitoring device, it compares the number of received initial warnings for each group, and the received number is It is characterized in that the transmission of polling signals to the monitoring devices in the group is started in descending order.

There is. Further, as the monitoring device for giving an initial warning to the monitoring center 20 when an earthquake detector described later operates, the monitoring devices 10a to 10e, 12a to 12e, 14 for each of the A to C groups.
a to 14e are sampled and selected in advance.

Here, the "initial alarm" is an emergency call from the monitoring device to the monitoring center when the seismic detector operates, and the monitoring devices 10a-10a are sampled.
e, 12a to 12e, 14a to 14e give an initial warning, and other monitoring devices 10f to 10n and 12f to 12
n, 14f to 14n are controlled so that the initial warning is not issued. This will prevent the simultaneous notification of an earthquake
It is possible to prevent congestion on the line and the switch.

The monitoring device for issuing the initial warning can be arbitrarily sampled. In this case,
In order to prevent communication congestion, it is preferable that the monitoring device that gives the initial warning sample a small number of monitoring devices with respect to the total number of monitoring devices. Therefore, it is recommended that the monitoring device that issues the initial warning be sampled in consideration of the number of monitoring devices and the line capacity. In addition, it is preferable that the monitoring device that gives an initial warning be a sampling of a monitoring device that is installed in a place where there is little vibration other than an earthquake. This is because it is possible to prevent notifications due to vibrations other than earthquakes, and to be able to more accurately understand the damage caused by earthquakes at the monitoring center.

As shown in FIG. 3, the monitoring device 10a includes an earthquake detector 28
And an elevator control device 30, a notification monitoring unit 32, and a transmission / reception unit 34.

The seismic detector 28 operates when the seismic intensity of a predetermined magnitude or more is detected, for example, when 40 gal or more is detected.

The elevator control device 30 controls the operation of the elevator. Especially when the earthquake detector 28 operates,
The elevator control device 30 controls the stop of the elevator and also supplies the earthquake abnormality information to the notification monitoring unit 32.

The notification monitoring unit 32 is used for the elevator control device 3
The abnormality information output from 0 is supplied to the transmitting / receiving unit 34 to control the notification to the monitoring center 20.

In the present embodiment, the monitoring devices 10a to 10e, 12a to 12e, 14 which are sampled.
The notification monitoring unit 32 of a to 14e is the elevator control device 3
The earthquake abnormality information supplied from 0 is supplied to the transmitting / receiving unit 34, and control is performed so as to issue an initial warning. On the other hand, the notification monitoring unit 32 of the other monitoring devices does not issue the initial warning even when the earthquake detector 28 operates and acquires the earthquake abnormality information. The notification monitoring unit 32 of these monitoring devices supplies seismic abnormality information to the transmission / reception unit 34 by receiving the polling signal from the monitoring center 20, and controls the notification to be performed. As a result, it is possible to prevent congestion of communication when an earthquake occurs.

The transmission / reception unit 34 is for communicating with the monitoring center 20, transmits the abnormality information from the notification monitoring unit 32 to the monitoring center 20, receives the polling signal from the monitoring center 20, and receives the notification monitoring unit. Supply to 32.

Although the monitoring device 10a has been described above as an example, the other monitoring devices have the same configuration.

Next, the structure of the monitoring center 20 will be described.

The monitoring center 20 includes a processing unit 36, a storage unit 38, a seismograph 40, a display unit 42, and a communication control unit 4.
4 and a transmission / reception unit 46.

The processing unit 36 controls each unit described below and processes the abnormality information reported from each monitoring device. In the present embodiment, the monitoring devices 10a to 10e, 12a to 12e, 14a to which the sampling is performed.
When the initial warning from 14e is received, the group A to
The comparison process is performed for each C, and then the order of the groups to which the polling signals from the monitoring center 20 are transmitted is determined.

The storage unit 38 stores parameters relating to processing of abnormality information of the processing unit 36 and control of each unit.
For example, a monitoring device that gives an initial warning and other monitoring devices,
And the groups to which they belong.

The seismic intensity meter 40 measures and records the seismic intensity of the earthquake. The observation value measured by the seismic intensity meter 40 is supplied to the processing unit 36 and can be displayed on the display unit 42 via the processing unit 36.

The display section 42 displays the observation data observed by the seismic intensity meter 40 and the abnormality information reported from each monitoring device supplied via the processing section 36.

The communication control unit 44 controls communication data with each monitoring device and maintenance office based on the processing result of the abnormality information of the processing unit 36. In the present embodiment, control is performed so that polling signals are sequentially transmitted to the monitoring device based on the comparison result of the initial alarms of the processing unit 36. Further, the communication control unit 44 controls the notification from the monitoring device to the maintenance offices 22, 24 and 26 in charge of the earthquake abnormality information.

The transmitting / receiving unit 46 is the transmitting / receiving unit 3 of each monitoring device.
4 and communicates abnormality information of each monitoring device to each maintenance office.

Next, the structure of the maintenance office will be described.

As shown in FIG. 3, the maintenance office 22 includes a receiving device 48, and the receiving device 48 receives the notification from the monitoring center 20. Here, the maintenance office 22 is described as an example, but other maintenance offices 24,
26 has the same configuration.

Next, the operation of the elevator earthquake remote monitoring system 1 of the present embodiment will be described. Figure 4
Elevator earthquake remote monitoring system 1 of the present embodiment
It is a figure which shows the flowchart of.

With the elevator running,
An earthquake occurs (S10). When the earthquake detector 28 operates, the elevator control device 30 performs the elevator stop control and supplies the earthquake abnormality information to the notification monitoring unit 32 (S12). Monitoring device 10a being sampled
When the information monitoring unit 32 of 10e, 12a to 12e, and 14a to 14e acquires the earthquake abnormality information, the transmitting / receiving unit 34 issues an initial warning to the monitoring center 20 (S14). At this time, the monitoring devices 10a to 10e, 12a to 12e, 14a
Monitoring devices 10a to 10e and 12a to 12 other than -14e
e, 14a-14e, even if the earthquake detector is operating,
No initial warning is given.

As a result, it is possible to prevent the congestion of the line and the exchange due to the simultaneous notification when an earthquake occurs. Also, the monitoring center can grasp the overall damage situation at an earlier stage by the initial warning.

Next, when the transmission / reception unit 46 of the monitoring center 20 receives the initial warning (Yes in S16), the initial warning is supplied to the processing unit 36 via the communication control unit 44,
The processing unit 36 determines the order of groups to start transmitting the polling signal (S18). In the present embodiment, the processing unit 36 compares the number of received initial warnings for each group, and determines the order in descending order of the number of received cases. For example,
When the number of initial warnings in the group A is 1, the number of initial warnings in the group B is 3, and the number of initial warnings in the group C is 5, the processing unit 36 receives a large number of groups that transmit the polling signal. The order, that is, the order of C group, B group, and A group is determined (S18). When the order is determined, the monitoring center 20 in this case starts transmitting a polling signal to the monitoring devices 14a to 14n of the C group, which is the first group (S20). If it is not possible to compare the number of received alarms, such as when the number of initial alarms in each group is the same in step 20, transmission of polling signals may be started in the order stored in the storage unit 38 in advance. In the present embodiment, the monitoring center 20 transmits the polling signal to all the monitoring devices in the C group, but the transmission of the polling signal to the monitoring devices that issued the initial warning may be omitted.

Upon receiving the polling signal, the notification monitoring unit 32, to which the earthquake abnormality information of the monitoring devices 14a to 14n of the C group is supplied, transmits the earthquake abnormality information in response to the polling signal (S22). When the monitoring center 20 receives the earthquake abnormality information from the monitoring device of the C group, the monitoring center 20 sequentially transmits the result to the maintenance office 26 in charge (S24), and the content of this notification is displayed on the display device (not shown) of the maintenance office 26. Displayed). As a result, the maintenance office 26 can dispatch a worker to the elevator where the earthquake is abnormal.

When the investigation by the polling signal to the monitoring devices of group C is completed (Yes in S26), the monitoring center 20 starts transmitting the polling signal to the monitoring devices of the next group (S28). When the seismic abnormality information is transmitted from the monitoring device of the group (S30), the result is transmitted to the maintenance office in charge (S32). In S34, it is judged whether or not the transmission of the polling signal to the monitoring devices of all the groups is completed.
The routine from 28 to S32 is repeated, and if completed, the process ends. In the present embodiment, if the transmission of the polling signal to the monitoring devices of the B group and the A group subsequent to the C group is completed, the process is terminated.

As described above, when an earthquake occurs, only the monitoring devices sampled are given an initial warning, and then the other monitoring devices send a polling signal based on the number of the initial warnings to obtain the earthquake abnormality information. Since it is decided to send the message, it is possible to preferentially investigate a group in which an abnormality is likely to occur, and it is possible to efficiently dispatch a maintenance office worker.

When the initial alarm is not received despite the occurrence of the earthquake (No in S16), for example, when the seismic detector of the monitoring device being sampled does not operate, polling from the monitoring center 20 is performed. Since no signal is transmitted, other monitoring devices cannot transmit earthquake anomaly information. In order to prevent such a situation, when the initial alarm is not received and the seismograph 40 of the monitoring center 20 exceeds the predetermined observation value (Yes in S36).
s), according to the order of the groups stored in advance in the storage unit 38, the transmission of the polling signal is started (S20),
The processing from S22 to S34 is performed. As a result, even if there is no initial warning, it is possible to find an elevator with an earthquake abnormality. The transmission order of the polling signals in this case can be stored in the storage unit 38 in the past history information or the alphabetical order of the group names as the transmission order. Also, regardless of the initial warning, the monitoring center 20
If the condition of the seismic intensity meter 40 for starting the transmission of the polling signal is set lower than the value at which the seismic detector 28 of the monitoring device operates, omission of investigation can be prevented.
For example, when the operating condition of the seismic detector of each monitoring device is set to 40 gal, the monitoring center may be set to start transmitting the polling signal when the seismograph measures 30 gal. In S36, if the seismograph 40 of the monitoring center 20 does not exceed the predetermined observation value (N in S36
o), the process ends.

[0046]

As described above, according to the present invention,
Since the monitoring devices that are geographically close to each other are grouped and the monitoring device that performs the initial warning when the earthquake detector operates is sampled and selected, it is possible to prevent the communication congestion at the time of the earthquake.

According to the invention, the monitoring center is
Regarding other monitoring devices, we decided to send a polling signal based on the initial warning and to send earthquake anomaly information, so it is possible to preferentially investigate the group in which an anomaly is likely to occur, Workers in the maintenance office can be efficiently dispatched.
