Description

The present invention relates to a work support device, an elevator system, and a work support method.

Conventionally, in elevators and other elevators, when performing on-site work such as maintenance work and failure recovery work, the monitoring center manages the completion of on-site work.
For example, in Patent Document 1, when the repair of a failure is not completed within a predetermined time at the monitoring center, the fact that the repair has not been completed is transmitted to a predetermined failure support destination to perform the repair work of the failure. The technology to support is described.

JP-A-2018-180801

As described in Patent Document 1, even in the past, if the worker has not been restored even after a predetermined time has passed since the worker was dispatched to the faulty part, the monitoring center contacts a supporter who supports the restoration work. However, the support department contacts the restoration workers and dispatches support workers. The predetermined time here may be, for example, an average working time required for recovery of a failed portion.

However, the conventional support for failure recovery work is support that is provided when the work is not completed even after the time originally required for the work has elapsed, and the support is provided during the failure recovery work. Even if the work was delayed for some reason, we could not provide support. For example, when a worker with a high degree of skill in the corresponding work performs the work, it is highly likely that the work will be completed in a time shorter than the average time, but conversely, in the case of an unfamiliar worker, the work is completed. The time to finish may be longer than the average time. Therefore, if support is provided under uniform conditions such as the passage of average work time, it may result in inappropriate support that does not reflect the actual progress of work, and eventually, until the elevator failure recovery. It may take extra time.

An object of the present invention is to provide a work support device, a work support system, and a work support method capable of recovering a failure at an early stage by optimizing the time for performing work support at the time of failure recovery work of an elevator. ..

In order to solve the above problems, for example, the configuration described in the claims is adopted.
The present application includes a plurality of means for solving the above problems. For example, in a work support device that supports recovery work of a failed elevator, a data management unit that acquires failure status data of the elevator and a data management unit. , The cause device estimation unit that estimates the cause device of the failure from the failure state data acquired by the data management unit, and the past case estimation unit that estimates the time required for the recovery work of the elevator based on the failure state data and the cause device. Based on the past response confirmation unit that confirms the worker skills of the workers who are executing the restoration work of the elevator, the work time estimated by the past case estimation unit, and the worker skills confirmed by the past response confirmation unit. , When the time setting unit that sets the time to give support instructions and the time after the operator starts the elevator restoration work exceeds the time set by the time setting unit, the supporter of the elevator restoration work It is equipped with a notification unit that selects and notifies the user.

According to the present invention, since the time for instructing the support for the restoration work of the elevator is set based on the equipment causing the failure and the skill of the worker in the field, the optimum time reflecting the actual skill of the worker is reflected. The time required for restoration work can be shortened.
Issues, configurations and effects other than those described above will be clarified by the description of the following embodiments.

Hereinafter, an example of an embodiment of the present invention (hereinafter, referred to as “this example”) will be described in detail with reference to the accompanying drawings.

[1. System-wide configuration]
FIG. 1 shows the overall configuration of a system (elevator system) including the elevator 110 of this example. As shown in FIG. 1, the elevator system of this example has a local work unit 100, which is a building in which an elevator performing restoration work is installed, and a monitoring unit connected to the local work unit 100 by a public network 1. A center 200 is provided.
The on-site work unit 100 includes an elevator 110, a monitoring device 120, and a on-site worker terminal 130 installed in the building.

The monitoring center 200 communicates with the monitoring device 120 of the local work unit 100 via the public network 1 to monitor the state of the elevator 110. Although FIG. 1 shows only one elevator 110, the monitoring center 200 can monitor a large number of elevators 110 installed in the monitoring area.

The monitoring device 120 provided in the on-site work unit 100 monitors the state of the elevator 110, determines whether normal operation is possible or is in a failed state, and transmits the determination result data to the monitoring center 200. ..
For example, the monitoring device 120 diagnoses the operating status of each part of the elevator 110 based on the detection data of various sensors installed in the elevator 110, and monitors the failure status data when the diagnosis result indicates that normal operation cannot be performed. It is transmitted to the center 200. The failure state data includes data indicating what kind of failure has occurred in the elevator 110.
For example, there are data indicating defective opening / closing of the car door, data indicating defective braking, and the like, and these failure state data are data detected by various sensors installed in the elevator 110. The data indicating the failure state of the elevator 110 is transmitted from the monitoring device 120 of the field work unit 100 to the monitoring center 200 as failure state data.

In addition to the state data of the failed device, the failure state data may include data indicating the state of the device that is operating normally. Further, in the case where the failure location can be diagnosed by the monitoring device 120, the data indicating the failure location as the diagnosis result may be included in the failure status data.

Here, it is assumed that the elevator 110 shown in FIG. 1 is in a state of failure, and a worker (local worker) is performing recovery work for the failure of the elevator 110.
The on-site worker is dispatched to the on-site work unit 100 by an instruction from the monitoring center 200 that has received the failure state data from the monitoring device 120 of the on-site work unit 100, and executes the failure recovery work.

The on-site worker reports the start and end of the restoration work to the monitoring center 200 side by the on-site worker terminal 130 of the on-site work unit 100. The local worker terminal 130 is a tablet terminal or a notebook computer owned by the local worker. The field worker terminal 130 also communicates with the monitoring center 200 via the public network 1 in the same manner as the monitoring device 120. As the public line network 1, a wired or wireless telephone line network or a communication line network such as the Internet is used.

The monitoring center 200 is a device that receives data transmitted from the monitoring device 120 and executes monitoring of the elevator 110, and is composed of, for example, a server composed of a computer and peripheral devices thereof.
As shown in FIG. 1, the monitoring center 200 includes a work support device 210, a display device 217, and a learning engine 220. Further, the monitoring center 200 side is provided with logistical supporter waiting area 230. It may be installed at a place different from the monitoring center 200.

The work support device 210 includes a data management unit 211, a cause device estimation unit 212, a past case estimation unit 213, a past correspondence confirmation unit 214, a push time setting unit 215, and a notification unit 216. Further, the work support device 210 is connected to a learning engine 220 which is an arithmetic processing unit that performs data processing necessary for processing in the work support device 210.

The learning engine 220 has a past state data storage unit 221 and a past correspondence record storage unit 222. Then, in the learning engine 220, the cause of the failure and the like are determined by using the past failure state data stored in the past state data storage unit 221 and the recovery record of the failure at that time stored in the past correspondence record storage unit 222. The learning process required for estimation is performed. An example of estimation processing using the learning engine 220 will be described later.
Further, a display device 217 for displaying the processing result of the work support device 210 is connected to the work support device 210.

The data management unit 211 of the work support device 210 performs a data management process for acquiring failure state data transmitted from the monitoring device 120 of the field work unit 100 to the monitoring center 200 via the public network 1. The failure state data acquired by the data management unit 211 is sent to the cause device estimation unit 212.
The cause device estimation unit 212 performs the cause device estimation process for estimating the cause of the failure based on the acquired failure state data. The learning engine 220 is used when the cause device estimation unit 212 estimates the cause of the failure.

That is, the causal device estimation unit 212 searches the past failure state data stored in the past state data storage unit 221 of the learning engine 220, and extracts the failure state data similar to the acquired failure state data. Then, the learning engine 220 reads out the failure recovery record for the searched past failure state data from the past correspondence record storage unit 222.
The causal device estimation unit 212 estimates the cause of the failure and the device that caused the failure based on the failure status data acquired from the data management unit 211 with reference to the read past recovery record.

The past case estimation unit 213 reads out the cause device estimated by the cause device estimation unit 212 and the failure state data received by the data management unit 211, and performs the past case estimation process. That is, the past case estimation unit 213 is composed of the failure difficulty level, the recovery work time, the corresponding workers, the number of workers, etc. from the past failure state data stored in the past state data storage unit 221 of the learning engine 220. Get the pattern and recovery time score.
The recovery time score is such that when the worker currently performing the recovery work performs the recovery work of the cause device estimated by the cause device estimation unit 212, the estimated time of the recovery work is shorter than the standard work time. It is a numerical value indicating whether it will be longer or longer. A specific example of the recovery time score will be described later. The past case pattern includes the work time required for the restoration work, and the past case estimation unit 213 can estimate the work time until the restoration work is completed from the work time required for the restoration work and the restoration time score.

The past correspondence confirmation unit 214 performs the past correspondence confirmation processing for confirming the worker skill of the worker who is currently performing the restoration work. To confirm this worker skill, the past case pattern estimated by the past case estimation unit 213 is collated with the past correspondence record storage unit 222 of the learning engine 220, and the local worker working in the local work unit 100 is in the same manner. It is judged from the information on how many times the work history of the past case pattern is. Specific examples of worker skills will also be described later.

The push time setting unit 215 uses the recovery time score estimated by the past case estimation unit 213 and the worker skill confirmed by the past response confirmation unit 214 to serve as a threshold value for the elapsed time to support the local worker (elapsed time). ) Is set. Performs time setting processing.
The notification unit 216 determines whether or not the push time set by the push time setting unit 215 has elapsed since the local worker terminal 130 of the local work unit 100 notifies the start of work, and the push time has elapsed. In the case, a support worker is selected and the dispatch of the selected support worker is notified. The notification by the notification unit 216 is given to, for example, the logistical supporter terminal 231 possessed by the logistical supporter waiting at the logistical supporter waiting area 230. Alternatively, the notification from the notification unit 216 is performed by displaying the information of the selected logistical supporter or the like on the display device 217 connected to the work support device 210.
When the logistical supporter information is displayed on the display device 217, the operator monitoring at the monitoring center 200 contacts the logistical supporter selected based on the information displayed on the display device 217.

When the notification unit 216 contacts the logistical support terminal 231 directly or via the operator, the logistical supporter who possesses the corresponding logistical support terminal 231 is dispatched to the local work unit 100 and is a local worker. Support the work by.
Alternatively, the logistical supporter who has been contacted by the logistical supporter terminal 231 from the notification unit 216 contacts the logistical supporter terminal 130 by telephone or e-mail, and provides necessary information (recovery work) for the work performed by the local worker. (Procedures, etc.) to provide support.

The past state data storage unit 221 and the past correspondence record storage unit 222 of the learning engine 220 receive new failure state data in the work support device 210 and take measures based on the failure state data each time. Data is added and recorded. When a new past correspondence record is stored in the past correspondence record storage unit 222, the learning engine 220 performs a learning process feeding back the new data and updates the values of the worker skill and the recovery time score. .. The learning engine 220 also performs learning processing every time new data is supplied, even when estimating the device causing the failure and the recovery time. Specific examples of updating the values of worker skills and recovery time scores will be described later.

[2. Hardware configuration example]
The monitoring center 200 including the work support device 210 shown in FIG. 1 can be configured by, for example, the computer shown in FIG.
The computer C shown in FIG. 2 includes a CPU (Central Processing Unit) C1, a ROM (Read Only Memory) C2, and a RAM (Random Access Memory) C3 connected to the bus C8, respectively. Further, the computer C includes a non-volatile storage C4, a network interface C5, an input device C6, and a display device C7.

The CPU C1 is an arithmetic processing unit that reads a program code of software that realizes a function performed by the monitoring center 200 from the ROM C2 and executes it.
Variables, parameters, etc. generated during the arithmetic processing are temporarily written in the RAM C3. Execution of the control process by the monitoring center 200 is realized mainly by the CPU C1 executing the program code.

For example, a keyboard, a mouse, or the like is used as the input device C6, and the operator uses the input device C6 to perform an input operation at the time of maintenance or inspection of the elevator.
The display device C7 is, for example, a liquid crystal display monitor, and the result of the control process executed by the computer by the display device C7 is displayed to the operator. The display device C7 is used as, for example, a display device 217 that displays information about logistical supporters.

For the non-volatile storage C4, for example, a large-capacity information storage medium such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive) is used. A program that executes a processing function performed by the monitoring center 200 is recorded in the non-volatile storage C4. Further, the past state data storage unit 221 and the past correspondence record storage unit 222 of the learning engine 220 are also composed of the non-volatile storage C4.
For the network interface C5, for example, a NIC (Network Interface Card) or the like is used. The network interface C5 transmits and receives various information to and from the outside via a LAN (Local Area Network), a dedicated line, and the like. Transmission and reception with and from the monitoring device 120 via the public network 1 is also performed via the network interface C5.

The monitoring center 200 is configured by the computer shown in FIG. 2 as an example, and may be configured by other arithmetic processing units other than the computer. For example, a part or all of the functions performed by the monitoring center 200 may be realized by hardware such as FPGA (Field Programmable Gate Array) or ASIC (Application Specific Integrated Circuit).

[3. Worker skill, recovery time score, push time example]
FIG. 3 shows four patterns A, B, C, and D regarding the worker skill α, the recovery time score β, and the push time handled by the work support device 210.

The worker skill α acquired by the past correspondence confirmation unit 214 is shown here as a value from 0 to 1. The higher the value (the closer the value is to 1), the higher the skill of the worker.
For example, if the work being judged has a certain number of experience of restoration work in the past case, the worker skill α of the corresponding worker is set to “1”. On the contrary, if there is no or little experience in the work being judged, the worker skill α of the corresponding worker is set to “0.5”.
However, in the case of relatively simple work, the worker skill α may be set to the same value “1” regardless of the worker.

The four patterns A, B, C, and D shown in FIG. 3 are examples in which the worker skill α is set in two stages of “1” and “0.5”, but the values from 0 to 1 are experienced. It may be set by changing it to a finer stage according to the number of times or the like. In addition, the stage of the worker skill α may be set separately according to various factors related to the skill of the worker other than the number of work experiences.
For example, the shorter the elapsed time since the last time the corresponding work was performed, the higher the value of the worker skill α is set, and when the elapsed time since the corresponding work is performed is long, the value of the worker skill α is set. May be set low.

The recovery time score β acquired by the past case estimation unit 213 is set to a value from 0 to 1 here. The higher the set value (the closer the value is to 1), the shorter the time required for the restoration work.
For example, if the time required for recovery work is short for a certain worker, the recovery time score β is set to “1”. On the contrary, when the time required for the recovery work is long, the recovery time score β is set to “0.5”. The recovery time score β is also set in two stages of “1” and “0.5” here, but it may be set by changing it to a finer stage.

The push time set by the push time setting unit 215 is set based on the worker skill α and the recovery time score β.
Here, the specific patterns A, B, C, and D shown in FIG. 3 will be described.

Pattern A is a case where the field worker has work experience and the work time is short for the restoration work currently being performed. In the case of this pattern A, the worker skill α becomes “1”. Then, when the recovery time score β of the work being executed in the pattern A is “1”, the push time is set to 30 minutes.
In the case of this pattern A, if 30 minutes have passed since the work by the field worker was started and the work support device 210 has not been notified of the end of the work, the notification unit 216 of the work support device 210 is a logistical supporter. Is selected and notified. That is, in the case of this pattern A, the worker skill α is “1”, and the recovery time score β is also “1” indicating that the work can be performed in the shortest time. In the case of this pattern A, it is considered that the possibility of logistical support to the worker is the lowest, so the push time is set to a relatively long 30 minutes.

Pattern B is a case where the field worker has work experience for the restoration work currently being performed and the estimated work time is long. In the case of this pattern B, the worker skill α becomes “1”. Then, when the recovery time score of the work being executed in the pattern B is "0.5", the push time is set to 15 minutes.
In the case of this pattern B, if 15 minutes have passed since the work by the field worker was started and the work support device 210 has not been notified of the end of the work, the notification unit 216 of the work support device 210 is rearward. Select a supporter and notify them. That is, in the case of this pattern B, the worker skill α is high “1”, and the recovery time score β is “0.5” indicating a long time, so the push time is shorter than that of pattern A15. Set to minutes.

Pattern C is a case where the field worker has no work experience and the estimated work time is short for the recovery work currently being performed. In the case of this pattern C, the worker skill α becomes “0.5”. Then, when the recovery time score of the work being executed in the pattern C is "1", the push time is set to 15 minutes.
In the case of this pattern C, if 15 minutes have passed since the work by the field worker was started and the work support device 210 has not been notified of the end of the work, the notification unit 216 of the work support device 210 is a logistical supporter. Is selected and notified. That is, in the case of this pattern C, the worker skill α is low “0.5”, and the recovery time score β is “1” indicating a short time. In the case of this pattern C, since the worker skill α is low, the push time is set to 15 minutes, which is shorter than that of pattern A and is equivalent to that of pattern B.

Pattern D is a case where the field worker has no work experience for the restoration work currently being performed and the estimated work time is long. In the case of this pattern D, the worker skill α becomes “0.5”. Then, when the recovery time score of the work being executed in the pattern C is "0.5", the push time is set to 7.5 minutes.
In the case of this pattern D, if 7.5 minutes have passed since the work by the field worker was started and the work support device 210 has not been notified of the end of the work, the notification unit 216 of the work support device 210 is rearward. Select a supporter and notify them. That is, in the case of this pattern C, the worker skill α is low “0.5”, and the recovery time score β is “0.5” indicating a long time. When both the worker skill α and the recovery time score β are low as in this pattern D, the push time is set to 7.5 minutes, which is shorter than the pattern B and the pattern C.

[4. Processing from the occurrence of a local failure to the selection of logistical supporters]
FIG. 4 is a flowchart showing a processing example of the work support device 210 from the occurrence of a local failure to the selection of logistical supporters.
When the on-site work unit 100 starts the failure handling work, the data management unit 211 of the work support device 210 determines whether or not the failure status data has been received (step S1). Here, when the data management unit 211 determines that the failure state data has not been received (NO in step S1), the process returns to the process of step S1.

Further, in step S1, when it is determined that the data management unit 211 has received the notification of the failure state data (YES in step S1), the cause device estimation unit 212 reads the failure state data received by the data management unit 211. , A device causing a failure is estimated from a state data matter similar to the past state data stored in the past state data storage unit 221 of the learning engine 220 (step S2).

Next, the past case estimation unit 213 reads out the cause device estimated by the cause device estimation unit 212 in step S2 and the failure data received by the data management unit 211. Further, the past case estimation unit 213 includes a past case pattern and recovery from the past state data stored in the past state data storage unit 221 of the learning engine 220, which is composed of a failure difficulty level, recovery work time, corresponding workers, number of people, and the like. Obtain the time score (step S3).

After that, the past correspondence confirmation unit 214 collates the past case pattern estimated by the past case estimation unit 213 in step S3 with the past correspondence record stored in the learning engine 220, and the local worker of the local work unit 100 similarly. Acquire the worker skill of how much the work history of the past case pattern is (step S4).

Then, the push time setting unit 215 pushes and supports the local worker from the recovery time score estimated by the past case estimation unit 213 in step S3 and the worker skill confirmed by the past correspondence confirmation unit 214 in step S4. A push time that serves as a threshold value is set (step S5).

After that, the notification unit 216 compares the elapsed time from the current work start with the push time, and determines whether or not the push time has been exceeded (step S6). If it is determined in step S6 that the current working time does not exceed the push time (NO in step S6), the determination in step S6 is repeated.
If it is determined in step S6 that the current work time has exceeded the push time (YES in step S6), the notification unit 216 selects a logistical supporter, and the logistical supporter terminal possessed by the selected logistical supporter. The logistical supporter notifies 231 of the support request (step S7).
The notification of the support request may be displayed on the display device 217 provided in the monitoring center 200 according to the instruction from the notification unit 216.

Further, the work support device 210 records a series of correspondence information from steps S2 to S7 in the past correspondence record storage unit 222 of the learning engine 220 after the local worker terminal 130 or the like notifies the completion of the restoration work. (Step S8), the failure handling work is completed.

[5. Example of screen requesting logistical support]
FIG. 5 is an example of the screen 300 displayed on the display device 217 of the monitoring center 200 based on the instruction from the notification unit 216. The screen 300 is for notifying that the logistical supporter needs support.
On the screen 300, the site information 301, the attendance information 302, the site estimation failure information 303, the push time 304, and the worker contact button 305 are displayed.

In the field of site information 301, detailed information of the site (site work unit 100 in FIG. 1) performing the failure recovery work is displayed. For example, the building name (building name), address, customer number, machine number, and elevator type (elevator, escalator, etc.) are displayed.
In the column of attendance information 302, the name and worker skill of the worker working at the site are displayed.
In the field of the local estimation failure information 303, information about an abnormality such as the cause device estimated by the cause device estimation unit 212 and a recovery time score are displayed.

In the push time 304 column, the push time (minutes) set by the push time setting unit 215 is displayed. Further, in the push time 304 column, the elapsed time (hours and minutes) from the start of the restoration work is displayed.
The worker contact button 305 is a button for making a call for a call to the logistical support terminal 231 possessed by the logistical supporter selected at this time. When the field of the worker contact button 305 is selected by the operator of the monitoring center 200, such as by clicking, the notification unit 216 of the work support device 210 makes a call to the logistical support terminal 231 to make a call. The operator can contact the logistical supporter.

Information (name, worker skill, etc.) about the selected logistical supporter may be displayed on the screen 300.
Further, in addition to the worker contact button 305, a contact button for contacting a local worker (calling for a call) may be provided.

[6. Example of updating worker skills and recovery time score after recovery work]
In step S8 of the flowchart of FIG. 4, when the newly corresponding record is updated and recorded in the past correspondence record storage unit 222 of the learning engine 220, the worker skill and the recovery time score are obtained by learning the learning engine 220. Can be updated.

Here, a learning example of the worker skill and the recovery time score will be described.
For example, when a worker goes to work for recovery work of a certain failure, the worker skill and recovery time score of the worker are as follows.
Worker skill α: 0.5
Recovery time score β: 0.5

The update of the recovery time score β after responding to the recovery work is
(Estimated recovery time-this work time) x evaluation coefficient + old recovery time score = new recovery time score. Here, the evaluation coefficient is 0.01. Examples 1 and 2 show examples of updating the recovery time score β below.
Example 1: When the estimated recovery time is 60 minutes, the working time this time is 80 minutes, and the time is over, the following calculation is performed.
(60 minutes-80 minutes) x 0.01 + 0.5 = 0.3
In this way, when the time is over, the recovery time score is updated to a low value according to the time exceeded.

Example 2: When the estimated recovery time is 60 minutes, the working time is 50 minutes this time, and the working time is reduced, the following calculation is performed.
(60 minutes-50 minutes) x 0.01 + 0.5 = 0.6
In this case, since the work time is reduced, the recovery time score β is updated to a high value according to the reduced time.

Update of worker skill α after responding to restoration work,
(Estimated recovery time-current work time) x evaluation coefficient + experience addition + old worker skill = new worker skill. Here, the evaluation coefficient is 0.01. The experience addition is a value added based on the experience of the corresponding work. Examples 3 and 4 show examples of updating the worker skill α below.

Example 3: When the estimated recovery time is 60 minutes, the working time this time is 80 minutes, and the time is over, the following calculation is performed.
(60 minutes-80 minutes) x 0.01 + 0.1 + 0.5 = 0.4
In this way, when the time is over, the worker skill α is updated to a low value according to the excess time.

Example 4: When the estimated recovery time is 60 minutes, the working time is 50 minutes this time, and the working time is reduced, the following calculation is performed.
(60 minutes-50 minutes) x 0.01 + 0.1 + 0.5 = 0.7
In this case, since the work time is reduced, the worker skill α is updated to a high value according to the reduced time.

FIG. 6 is a table showing an example in which the update described so far is performed.
That is, at the time of failure, when the worker skill α is 0.5 and the work time is exceeded, the worker skill α is updated to 0.4, and when the work time is reduced, the worker skill α is 0. Updated to 0.7.
Also, when the recovery time score β is 0.5 and the work time is exceeded, the recovery time score β is updated to 0.4, and when the work time is reduced, the recovery time score β is updated to 0.6. To.

As described above, by updating the worker skill α and the recovery time score β, the push time was 7.5 minutes at the time of this recovery work, but when the work time is exceeded, it is 3.6 minutes. Is shortened to. On the other hand, when the working time is shortened, it is extended to 12.6 minutes.
