Description

The present invention relates to a recovery support method for an elevator recovery support system that supports elevator recovery work when a disaster involving a power outage occurs, and an elevator recovery support system.

When a disaster occurs over a wide area due to an earthquake or the passage of a typhoon, and many elevators and escalators installed in many buildings stop working, elevator maintenance companies are required to quickly restore the elevators that are out of service. be done. Here, the elevator refers to passenger transport equipment installed in a building, such as an elevator or an escalator.

Generally, elevator maintenance companies monitor the operating status of elevators and escalators by connecting monitoring terminals installed in elevators and escalators installed in customer buildings to a control center using a public network. The monitoring terminal installed in the elevator sends failure information and abnormality information to the control center, which allows the control center to grasp the occurrence of failures and abnormalities in the elevator (in the following, failure information and abnormality information Information related to disasters such as disasters is collectively referred to as "disaster information").

In particular, when an earthquake occurs or a typhoon passes through, disaster information related to earthquakes, flooding, etc. is transmitted from a large number of elevators from monitoring terminals. In addition, the monitoring terminals installed in the elevators monitor any failures or abnormalities in the building's power supply system, and are configured to send power outage information to the control center in the event of a power outage. There is.

For example, Patent Document 1 (Japanese Unexamined Patent Publication No. 2019-3431) describes a method for supporting recovery of elevators and escalators when a wide-area disaster involving a power outage occurs. It has been shown to ensure that high alerts are received without delay.

In other words, if a power outage is detected at a time included in the time zone indicated in the regional power outage information, the system is configured to send a report to the control center after a predetermined standby time has elapsed since the power outage was detected. ing.

Thereby, when a local power outage occurs, it is possible to suppress all the security devices from simultaneously transmitting a power outage report indicating that a power outage has occurred to the control center. Therefore, an increase in communication traffic in the communication line network is suppressed.

JP2019-3431A

By the way, when a wide-area disaster accompanied by a power outage occurs, disaster information and/or power outage information is transmitted from the monitoring terminals of the elevators of each building to the control center. Furthermore, when a wide-area disaster occurs, power outages and power restorations often occur repeatedly, and the amount of power outage information that is notified to the control center of the occurrence of a power outage becomes enormous.

As a result, the control center was unable to accurately manage the occurrence of disaster information and power outage information, and even though maintenance personnel were requested to be dispatched to the disaster site based on the disaster information, the power outage occurred at the disaster site. Situations like this may occur. As described above, the issue is how to provide recovery support in the event of a wide-area disaster accompanied by a power outage, such as unnecessary dispatch of maintenance personnel to the disaster site.

Note that the recovery support method described in Patent Document 1 is aimed at suppressing an increase in communication traffic, and does not take into consideration accurately determining the dispatch of maintenance personnel to provide prompt recovery support. .

The purpose of the present invention is to determine the power outage situation in the event of a wide-area disaster and to appropriately notify buildings that require the dispatch of maintenance personnel, thereby enabling prompt restoration of elevators and escalators in the event of a disaster. An object of the present invention is to provide a recovery support method for an elevator recovery support system and an elevator recovery support system.

The features of the present invention are:
collecting disaster information and power outage information in a disaster area;
a step of checking the relationship between the collected disaster information and power outage information and determining whether the building requires a request for dispatch of maintenance personnel;
a step of identifying areas where power has been restored based on the power restoration rate in the disaster area and/or the power outage recurrence rate;
The present invention provides an elevator recovery support method that sequentially executes the following steps: identifying a building in an area where power has been restored that requires a request for maintenance personnel to be dispatched, and notifying the request for dispatch.

According to the present invention, by determining the power outage situation in the event of a wide-area disaster and appropriately notifying buildings that require the dispatch of maintenance personnel, it is possible to quickly restore elevators and escalators in the event of a disaster. can.

Further, the RAM 104 has storage areas for a disaster information storage section 11c, a power outage area information storage section 11d, and a disaster property information storage section 11e. Furthermore, in addition to the RAM 104, each of the above-mentioned information storage units can use a dynamic RAM with power backup, an EEPROM without power backup (for example, a flash ROM), or the like.

The computer system 100 receives information from various sensors as input signals, including disaster information and power outage information from the elevator monitoring terminals 31-0 to 31-N, through the I/O device 105, and uses this information as an input signal. Based on this, the CPU 102 executes arithmetic processing, and outputs, for example, display information obtained as a result of this calculation to the display terminal 14 as output information.

The control system 11 and the display terminal 14 are connected through an in-house network 13, and display information from the control system 11 is broadcast on the display terminal 14 used by air traffic controllers. Note that the notification can be performed by display on a display screen or by sound from a speaker.

On the display terminal 14, display information (alarm information) is transmitted from the control system 11, and based on the transmitted alarm information, the controller instructs maintenance personnel in a remote location to request dispatch. be able to.

The control center 1 is connected to a public network 2, and can use, for example, a public IP network provided by a communication carrier. Via this public network 2, the control center 1 can obtain disaster information and power outage information.

Elevators (passenger transport equipment) 32 such as elevators and escalators have been delivered and installed in a customer building 3, which is a building. The elevator 32 is equipped with a monitoring terminal 31, and a monitoring unit 31b monitors the operational status of the elevator 32, such as failures, abnormalities, and power outages. It is also connected to the control center 1 via the communication unit 31a and the public network 2, and when a failure, abnormality, power outage, etc. occurs in the monitored elevator 32, this information is sent to the control center 1 as an alert. do.

Also connected to the public network 2 is a DMZ server 4 used by an elevator maintenance company. The DMZ server 4 has the role of performing data coordination between the control center 1 and the cloud platform 5 through the data coordination section 41.

The cloud platform 5 is configured to reflect the data of the control system 1 through a data linkage unit 51, provide information to maintenance personnel through a disaster information map display unit 52, and provide information to customers through a disaster information display unit 53. is configured to do so.

The disaster information map display section 52 of the cloud platform 5 is connected to the maintenance terminal 6 via the public network 2. The maintenance terminal 6 is generally a terminal such as a smartphone, a tablet terminal, or a personal computer that is connected to a network and carried by a maintenance worker.

The above is the configuration of the elevator recovery support system according to this embodiment, and this embodiment is particularly characterized by the recovery support function of the control system 11.

Next, an elevator recovery support method executed by the control system 11 will be described. This recovery support method is particularly executed by the computer system shown in FIG. 6, but the computer system is operated by a control program, and the control steps can be regarded as a control function section.

The basic recovery support method of this embodiment is as follows:
It is connected via a network to monitoring terminals installed in elevators and escalators installed in multiple buildings in a given area, and monitors the operating status of the elevators and provides support for elevator recovery in the event of a disaster. In the recovery support method of the elevator recovery support system consisting of a monitoring center,
The first step is to collect disaster information and power outage information in the disaster area;
a second step of checking the relationship between the collected disaster information and power outage information and determining whether the building requires a request for dispatch of maintenance personnel;
a third step of identifying areas where power has been restored based on the power restoration rate in the disaster area and/or the power outage recurrence rate;
The present invention is characterized in that a fourth step of identifying a building in an area where power has been restored that requires a request for maintenance personnel to be dispatched and notifying the request for dispatch is sequentially executed.

Furthermore, if the control step is regarded as a control function section, the basic recovery support system of this embodiment is as follows:
It is connected via a network to monitoring terminals installed in elevators and escalators installed in multiple buildings in a given area, and monitors the operating status of the elevators and provides support for elevator recovery in the event of a disaster. In the elevator recovery support system consisting of a monitoring center,
The monitoring center is equipped with monitoring terminals and a control system connected via a network.
The control system is

a relevance determination function unit that checks the relevance of the collected disaster information and power outage information and determines whether the building requires a request for dispatch of maintenance personnel;
a power restoration area identification function unit that identifies areas where power has been restored based on the power restoration rate in the disaster area and/or the power outage recurrence rate;
The present invention is characterized in that it includes a notification function unit that identifies buildings in areas where power has been restored that requires a request for the dispatch of maintenance personnel, and issues a notification of the request for dispatch.

The elevator recovery support method and recovery support system will be described below using the control flows shown in FIGS. 2A and 2B. As described above, the control step can be regarded as a functional section.

Here, the control flows in FIGS. 2A and 2B describe the control operations at the maintenance terminal 6 and the customer terminal 7 and the control operations at the control system 11, respectively, and the control flows between the maintenance terminal 6, the customer terminal 7, and the control system 11. The communications that occur between them are indicated by the dashed lines between these control flows. First, the control flow of the control system 11 will be explained, and then the control flow of the maintenance terminal 6 and the customer terminal 7 will be explained.

≪Step S1≫
In step S1, a notification of disaster information from the monitoring terminal 31 of the customer building 3 is received by the communication unit 11a via the public network 2. If it is not received, it remains on standby, and if it is received, it moves to step S2.

≪Step S2≫
In step S2, when the disaster information is received, the disaster occurrence determination unit 12a determines that a disaster has occurred in the area where the customer building 3 where the disaster information was reported is located. When this disaster determination is completed, the process moves to step S4.

≪Step S3≫
In step S3, the disaster occurrence determination unit 12a issues a disaster ID for identifying the type of each disaster, and registers it in the disaster information storage unit 11c in the form of a "disaster management table" shown in FIG. For example, when an earthquake occurs and multiple aftershocks occur in a short period of time, the disaster ID can be used to determine whether to manage them as the same disaster or as separate disasters. I can do it. Once the disaster ID is issued and registered, the process moves to step S4.

≪Step S4≫
In step S4, the communication unit 11a receives the power outage information from the monitoring terminal 31 of the customer building 3 via the public network 2. Here, since a power outage generally occurs after a disaster occurs, registration of the disaster ID is first performed in advance. Note that if the power outage information is not received, other processing is executed, but in this embodiment, it is assumed that the power outage information is reported, so in the following, the power outage information is not reported. The explanation will proceed assuming that the message has been received. Then, upon receiving the power outage information, the process moves to step S5.

≪Step S5≫
In step S5, upon receiving the power outage information, the disaster occurrence determination unit 12a determines that a power outage has occurred in the area where the customer building 3 where the power outage information was reported is located. When this power failure determination is completed, the process moves to step S6.

≪Step S6≫
In step S6, the disaster occurrence determining unit 12a registers the power outage area where the power outage occurred as an area code together with the disaster ID in the power outage area information storage unit 11d in the form of a "power outage area management table" shown in FIG. As a result, the disaster ID and power outage area code are linked. When the registration of this power outage information is completed, the process moves to step S7.

≪Step S7≫
In step S7, in order to identify the building where the power outage has occurred, the disaster occurrence determination unit 12a stores the building code indicating the building together with the power outage area code in the disaster property information storage unit 11e in the "disaster property management table" shown in FIG. ”. This will link the building code and power outage area code. When the registration of this building code is completed, the process moves to step S8.

By executing steps S1 to S7 described above, each management table is completed. When the control system 11 recognizes that a disaster and a power outage are occurring simultaneously in the same area, it executes the following control steps from step S8 onwards.

≪Step S8≫
In step S8, a notification from the monitoring terminal 31 of the customer building 3 is received by the communication unit 11a via the public network 2. When the alarm is received, the process moves to step S9.

≪Step S9≫
In step S9, when the control system 11 receives a notification from the monitoring terminal 31 installed in the customer building 3, it first determines whether the notification is a power outage information notification or a failure information notification. This determination determines whether a request for dispatch of maintenance personnel is necessary or not.

In other words, if there is a power outage, restoration support for elevators and escalators cannot be provided, so issuing a power outage information would be a wasteful dispatch request. If the received alert is a power outage information alert, the process moves to step S10, and if the received alert is a disaster information alert, the process moves to step S13.

<<Step S10>>
Since the alert received in the previous step S9 was power outage information, in step S10, the repeated power outage determination unit 12b refers to the disaster property management table of the disaster property information storage unit 11e, and searches for the same building in the same disaster area. Determine whether there is any information about a power outage that has been restored that was received from the object in the past. If there is an announcement of power outage information that has been restored, the process moves to step S11, and if there is no information that power has been restored, the process moves to step S13.

<<Step S11>>
In step S11, if there is a repeated power outage, the repeated power outage determination unit 12b determines that it is a repeated power outage. If it is confirmed that the power outage is repeated, the process moves to step S12.

<<Step S12>>
In step S12, since it is determined that there is a repeated power outage, the repeated power outage determination unit 12b clears the dispatch request flag based on the dispatch of disaster information linked to the dispatch of past power outage information, and the dispatch request is unnecessary. Execute the settings.

In other words, in a building during a power outage, even if maintenance personnel are dispatched, restoration work cannot be carried out unless the power is restored, so the dispatch request flag is cleared. When the dispatch request flag is cleared, the process moves to step S13.

<<Step S13>>
In step S13, processing after the control steps of step S9, step S10, and step S12 is executed. This step S13 is for checking the relationship between the notification of power outage information and the notification of disaster information.

To confirm this relationship, a dispatch request flag is generally set when a disaster information alert is input, but in a building with a power outage, even if maintenance personnel are dispatched, the dispatch request flag is not activated. The idea is to stop transmitting disaster information to the display terminal 14 until the power is restored, since recovery work for the cause of the disaster cannot be carried out.

Therefore, the relationship between disaster information and power outage information is checked in step S13 when the past power outage information for the building has already been restored and when the past power outage information has not been restored. This check identifies buildings that require maintenance personnel to be dispatched.

In this way, if past power outage information has already been reported, the dispatch request flag in the disaster property management table of the disaster property management section 11e is set to "1" and registered, and the past power outage information is If the alert indicates that the power has not been restored (power has not been restored), the dispatch request flag in the disaster property management table of the disaster property management unit 11e is set to "0" and registered.

In FIG. 5, the dispatch request flag No. 1 is set to "1". Although power has been restored to No. 3, the dispatch request flag is not set to "1" because the second power outage information has been issued at No. 5. When step S13 is completed, the process moves to step S14 and step S15.

<<Step S14>>, <<Step S15>>
Next, a method for calculating the power restoration rate and power outage recurrence rate will be explained. The calculation of the power restoration rate and the power failure recurrence rate can be performed at regular intervals (for example, every 30 minutes). Therefore, steps S14 and S15 may be executed using a time interrupt (interrupt using a timer) every 30 minutes.

First, calculation of the power restoration rate can be executed by the power restoration rate calculation unit 12c by referring to data of the disaster property management unit 11e. Here, the power restoration rate is calculated by referring to whether the power restoration date and time of each power outage information notification is registered. It can be obtained by dividing the number of alarms (PRN) by the total number of alarms (PON) of received power outage information (PRN/PON). The determined power recovery rate is stored in a predetermined area of the RAM 104 and used in the next step S16.

Here, the number of issued power outage information in which power restoration date and time is registered and the total number of power outage information issued include only the latest power outage information issued in the building code. This is to exclude repeated power outage notifications.

Further, the calculation of the power failure recurrence rate can be executed by the power failure recurrence rate calculation unit 12d by referring to the data of the disaster property management unit 11e. Here, the power outage recurrence rate can be calculated based on the number of new power outage information notifications received from before a predetermined time (for example, one hour).

In other words, the number of received power outage information reports from the current time to the first predetermined time a predetermined time ago is calculated as the number of power outage information notifications received from the first predetermined time to the second predetermined time a predetermined time before It is calculated by dividing by the number of messages received. For example, if the number of power outage information alerts received from one hour ago to the current time is 50% of the number of power outage information alerts received from two hours ago to one hour ago, the power outage recurrence rate is It shall be 50%. The obtained power failure recurrence rate is also stored in a predetermined area of the RAM 104 and used in the next step S16.

When the power restoration rate is determined in step S14 and the power failure recurrence rate is determined in step S15, the process moves to step S16.

<<Step S16>>
In step S16, as a result of calculating the power restoration rate and power failure recurrence rate, the power restoration rate exceeds a predetermined reference value (e.g. 80%), and the power failure recurrence rate is less than or equal to a predetermined reference value (e.g. 10%). If there is a region where the power has been restored, that region is considered to have been restored, and the date and time of power restoration is registered in the power outage region information storage unit 11d in association with the power outage region code.

Here, in step S16, the power restoration area is specified using both the power restoration rate and the power outage recurrence rate, but the power restoration area may be specified using either the power restoration rate or the power outage recurrence rate. is also possible. When the identification of the power restoration area is completed, the process moves to step S17.

<<Step S17>>
In step S17, disaster information is announced on the display terminal 14 for the restored areas that are registered as having been restored. That is, if the building for which the dispatch request flag of the disaster property management department 11e is set to "1" in step S13 is included in the power restoration area, this dispatch request flag is set to "1". Notification of building disaster information to the display terminal 14 is executed. When the display terminal 14 is notified of the disaster information, the process moves to step S18.

<<Step S18>>
When the notification of disaster information is displayed on the display terminal 14, an instruction to request dispatch is sent to the maintenance personnel through the operation of the air traffic controller. Note that necessary information can be extracted from the management tables shown in FIGS. 3 to 5 and sent to the dispatch request.

In this way, by determining the power outage situation in the event of a wide-area disaster and appropriately transmitting buildings that require maintenance personnel to the maintenance terminal, it is possible to quickly restore elevators and escalators in the event of a disaster. can.

Next, the control flow of the maintenance terminal 7 of the maintenance worker and the customer terminal of the customer will be briefly explained.

<<Step S19>>
In step S19, when it is determined that a disaster has occurred in step S2 on the control center side, the disaster situation at the site is provided to the maintenance terminal 6 via the cloud platform 5 in the form of a pin plot on a map, Maintenance staff will be able to grasp the disaster situation within their own jurisdiction. Further, the customer can check the operating status of the elevators in the building managed by the dashboard application on the customer terminal 7.

≪Step S20≫
In step S20, when it is determined in step S4 on the control center side that a power outage has occurred in a certain building, a message is sent to the maintenance terminal 6 and customer terminal 7 via the cloud platform 5 indicating that the building is under power outage. Display some information. Information provided to the maintenance terminal 6 and customer terminal 7 via the cloud platform 5 is updated as needed.

<<Step S21>>
In step S21, if it is determined in step S6 on the control center side that a power outage is occurring in a certain area, power outage area information is provided to the maintenance terminal 6 and customer terminal 7 via the cloud platform 5. and display power outage area information.

<<Step S22>>
In step S22, when the power restoration area is searched in step S16 on the control center side, power restoration area information is provided in the form of a pin plot to the maintenance terminal 6 and the customer terminal 7 via the cloud platform 5. This allows maintenance personnel to grasp the status of power restoration within their area of jurisdiction. Additionally, the display on the dashboard application of the customer terminal 7 is also updated, allowing the customer to check the power restoration status of the buildings they manage.

<<Step S23>>
In step S23, when a dispatch instruction is requested in step S18 on the control center side, the dispatch request is transmitted to the maintenance terminal 6 via the cloud platform 5. When maintenance personnel receive dispatch instructions from the control center 1, they are dispatched to the building for which restoration support is to be performed and carry out restoration work. As a result, recovery support can be given priority to areas where power has been restored.

FIG. 7 shows a display screen displayed on the maintenance terminal 6 as a reference example. The location of the building, the power outage area, and the power restored area are displayed on the map on this display screen. Furthermore, additional information can be superimposed and displayed as text data on top of this information. The configuration of the display screen can be appropriately configured by the system designer.

As described above, the present invention includes the steps of collecting disaster information and power outage information in the disaster area, checking the relationship between the collected disaster information and power outage information, and dispatching maintenance personnel based on the disaster information. a step of determining whether the building requires a request; a step of determining an area where power has been restored based on a power restoration rate in the disaster area and/or a power outage recurrence rate; The recovery support method is characterized by the step of identifying a building in a electrified area that requires a request for maintenance personnel to be dispatched, and notifying the request for dispatch.

According to this, in the event of a wide-area disaster, it is possible to quickly restore elevators and escalators in the event of a disaster by determining the power outage situation and appropriately transmitting buildings that require the dispatch of maintenance personnel to a maintenance terminal. I can do it.
