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

  When performing maintenance work such as an elevator, an operator performs various work in various places according to the work contents of the day, such as in a machine room, a hoistway, in a car, or on a car. Therefore, if you notice that a tool has been misplaced after work, you cannot immediately know where to search. In the embodiment, the maintenance work performed by the worker on the day is determined in advance, and attention is paid to the fact that the maintenance work, the work place, and the tool have a series of correspondences. It uses a correspondence relationship to efficiently estimate a misplaced place and assist the worker.

Hereinafter, an example (Example 1) of an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram illustrating an example of the overall configuration of the first embodiment.
The work tool 1 is a tool such as a pliers or a screwdriver used in maintenance work, or a part such as a screw or a nut exchanged in the maintenance work. These are collectively referred to as a work tool 1. The camera 2 is a camera that is carried by the worker 3 and is attached to the head or chest of the worker 3 to photograph the work. The shooting interval may continue to be taken at a predetermined interval like a moving image, or a predetermined image may be taken by an operation of the operator 3.

  The worker 3 actually performs work on site. The portable terminal 4 is a terminal carried by the worker 3 and acquires an image of the work tool 1 photographed by the camera 2 through communication. The photographing tool display 4 a is a display example of an image of the work tool 1 acquired from the camera 2. The network 6 is a network for performing communication among the mobile terminal 4, the monitoring device 7, and the elevator control device 5, and may be wired or wireless. The elevator controller 5 acquires elevator control information. The monitoring device 7 is provided in the monitoring center and grasps the status of each elevator by communicating with each elevator.

FIG. 2 is a block diagram illustrating a configuration example of the monitoring device 7 according to the first embodiment.
The monitoring device 7 includes a communication unit 701, a work-specific tool recording unit 702, a work schedule recording unit 703, a tool recording unit 704, an image recording unit 705, a control information recording unit 706, a control unit 707, and a memory 708.

  The communication unit 701 transmits and receives data via the network 6. The work-specific tool recording unit 702 includes an elevator model, work contents (for example, brake overhaul, rail lubrication, fluorescent lamp replacement, etc.), work place (for example, a machine room, on a car, in a car, a pit, etc.) and tools used. , A database recorded in association. Details will be described with reference to FIG. The work schedule recording unit 703 is a database that records work scheduled by the worker 3. Details will be described with reference to FIG.

  The tool recording unit 704 is a database that records the tools extracted by the tool extraction unit 728 described later. The image recording unit 705 is a database that records an image received from the mobile terminal 4 together with shooting time information. The control information recording unit 706 is a database that records elevator control information received from the elevator control device 5. The control unit 707 is means for executing processing in the memory 708, which will be described later, and is specifically a CPU (Central Processing Unit). The memory 708 includes a work schedule creation unit 718, a tool extraction unit 728, a comparison unit 738, a misplaced place estimation unit 748, a result output unit 758, and a work place estimation unit 768.

The work schedule creation unit 718 extracts the work that the worker 3 actually performs on the day from the work-specific tool recording unit 702, and performs the work in the order in which the work is performed based on the data that associates the work content, the work place, and the tool used. Create work schedules side by side.
The tool extraction unit 728 extracts a tool shown in an image captured by the worker 3 after work and transmitted via the network 6, and records it in the tool recording unit 704 as a tool possessed by the worker 3. To do. As a tool extraction method, an existing image processing technique may be used. For example, a plurality of images obtained by photographing a predetermined tool at various angles and conditions are prepared, and local feature amounts such as color, edge, SIFT (Scale-Invariant Feature Transform) are extracted from each of the images, and correct data Create Similarly, colors, edges, and local feature amounts are extracted from the determination target image. If the feature values of the correct answer data and the determination target image are within a predetermined range, a predetermined tool appears in the determination target image. Recognize.

  The correct answer data may be stored in advance in a database (not shown). If tool information can be received directly from the portable terminal 4, the acquired tool information may be stored in the tool recording unit 704 without performing image processing. The comparison unit 738 compares the tool recorded on the work schedule recording unit 703 and used by the operator 3 on the day with the tool possessed by the operator 3 recorded on the tool recording unit 704, Alternatively, an inappropriate tool that does not match is extracted. The misplaced place estimation unit 748 extracts the missing tool extracted by the comparison unit 738 and the work place corresponding to the missing tool recorded in the work schedule recording unit 703.

  When a plurality of the work places are extracted, the nearest place where the worker 3 worked is further extracted. Thereby, it can be estimated that the missing tool has been misplaced between the place where the worker 3 worked most recently and the current time point. A specific estimation method will be described later.

  The result output unit 758 outputs data for causing the portable terminal 4 to display the misplaced place estimated by the misplaced place estimating unit 748 via the network 6. The result output unit 758 may output data to a display unit (not shown) used by a monitoring person in the monitoring device 7 and contact the worker 3 via the monitoring person. The work place estimation unit 768 estimates the work place of the worker 3 at a predetermined time based on the control information recorded by the control information recording unit 706 and the acquisition time information of the control information.

  FIG. 3 shows the contents of data recorded in the work-specific tool recording unit 702. As shown in FIG. 3, the model, work content, work place, and tool to be used are recorded in association with each other. For example, the work places when the work B of the model A is performed are the work place A and the work place C. The tools used at the work place A are tools A, B, and D, and the tools used at the work place C are tool A, tool E, and tool F. Note that general work time information necessary for each work and each work place may be added together. This work time information can be used to calculate the work end time if a work start time is set when a work schedule described below is created. The work-specific tool recording unit 702 is preferably updated by adding data each time a new model is introduced.

  FIG. 4 shows an example of a work schedule recorded in the work schedule recording unit 703. In the work schedule recording unit 703 shown in FIG. 4, the worker 3 is scheduled based on the model scheduled for patrol by the worker 3 on the day and the planned work from the tool-specific tool recording unit 702 in FIG. 3. A list of extracted work is recorded. Furthermore, the work performed by the worker 3 on the day (in FIG. 4, work A and B for model A, work A for model B, work C and A for model C) is recorded in chronological order. The work performed by the worker 3 is created for each date and the worker 3. In addition, a list of tools to be used for all work on the day is extracted as a used tool list. In FIG. 4, tools A, B, D, E, and F are recorded as tools that the worker 3 takes out.

  In addition, by inputting the work time for each work and each work place (scheduled work start time, scheduled work end time, etc.) in the work schedule, what kind of work of which model and where at any time when searching for a tool to be described later You can see what you are doing.

FIG. 5 is a diagram showing an example of extraction of insufficient tools in the comparison unit 738. FIGS. 5A1 and 5A2 are recognized before the departure of the sales office and the tool to be used when the operator 3 checks the sales office. The tool that was made is shown. 5 (B1) and (B2) show tools recognized after completion of a predetermined work (work of model C in FIG. 4) in addition to the tools in FIGS. 5 (A1) and (A2).
In FIG. 5A1, the scheduled tool list (tools A, B, D, E, and F) recorded in the work schedule recording unit 703 and the tool recording unit extracted by the tool extraction unit 728 before leaving the business office. Since the tools (tools A, B, D, E, and F) recorded in 705 coincide with each other, it is determined that there is no missing tool or inappropriate tool removal.

  In FIG. 5A2, the scheduled tool list (tools A, B, D, E, and F) and the tools (tools A, B, C, D, E, and F) recorded in the tool recording unit 705 are compared. As a result, it is shown that the tool B is missing as a tool recognized before leaving the sales office. That is, it is understood that the user forgets to take out the tool B and tries to take out the tool C inappropriately.

  In FIG. 5 (B1), since the tools (tools A, B, D, E, F) extracted from the image transmitted after the completion of the work of the model C match the scheduled tool list, there are insufficient tools. It can be judged that there is not. Instead of the scheduled tool list, the presence / absence of a missing tool may be determined by comparing with a tool recognized before departure from the sales office.

In FIG. 5 (B2), only tools A, B, D, and F are extracted from the image transmitted after the completion of the work of the model C, and the scheduled tool list (tools A, B, D, E, As a result of comparing F), it can be determined that the tool E is insufficient. In this case, the misplaced place estimation unit 748 searches for a work place where the tool E was last used based on the work schedule.
Specifically, the tool E should have been used at the work place C in order to perform the work C of the model C at the time indicated by the final use place determination 41 of the shortage tool in FIG. Therefore, in addition to the work place C, the work places A and D included in the work place where the work A of the model C, which is the next work, is performed are notified to the worker 3 as the search place candidates 42.

  In addition, there is a high possibility that the tool will be left and forgotten immediately after the end of the work. In such a case, a notification is given to preferentially search for the work place C determined in the final use place determination 41 of the shortage tool. Thus, search support can be performed more efficiently. If the check is performed not after model C as shown in FIG. 5 but when the work is completed for each model, the missing tool can be found earlier.

FIG. 6 shows an example of a processing flow of the control unit 704 when checking the tool when the worker 3 finishes the work.
First, a tool list used on the day by the worker 3 is acquired from the work schedule recording unit (S601). Then, it is checked whether an image is received from the camera 2 (S602), and the check is repeated until an image can be acquired (NO in S602). If it is determined in step S602 that an image has been acquired from the camera 2 (YES in S602), the tool shown in the image is extracted from the acquired image by the tool extraction unit 728 (S603). When there are a plurality of tools, the same image may be processed as many as the number of tools to be checked.

  Next, all the extracted tools are compared with the list of tools to be used, and it is determined whether or not the tools match (S604). In step S604, if all the extracted tools match the intended use tool list (YES in S604), permission to complete the work is issued (S605). In step S604, if there is a tool that does not match the tool list to be used among all the extracted tools (NO in S604), the missing tool and the search tool candidate for the missing tool are output to the portable terminal 4 (S606). ).

  In step S606, a mismatched tool (basically a missing tool if it is after work) is output to the mobile terminal 4, and the final use of the target missing tool is determined from the work schedule recorded in the work schedule recording unit 703. A place is extracted, and a search place candidate 42 is output. Even if all the used places are output as the search place candidates 42 as well as the final used place, it is possible to expect an effect of searching for the missing tool earlier than searching all the working places.

  A plurality of images are acquired without acquiring and determining one image from the camera 2, and Steps S <b> 602 and S <b> 603 are performed for each of the images, and the logical sum of all the tools shown in the image is obtained. May be recorded in the memory 708, and it may be determined in step S604 whether all tools have been extracted from the used tool list. For example, if even one tool A is shown in a plurality of images, it is determined that tool A is “present”. The same applies to other tools.

  In that case, the trouble of copying all the tools on one image can be saved. In addition, when checking a tool when it is not after work, such as when leaving a business office, there is no work schedule to be referenced in step S604. For this reason, when a tool mismatch occurs, the mismatched tool is displayed as forgetting to take out the tool or taking out an unnecessary tool.

  In the first embodiment, the misplacement check is performed at the end of the work in the work schedule. However, the work progress may be input to the portable terminal 4 before the tool check. In this case, if the schedule after the current work is excluded from the search range in the work schedule, the missing tool can be efficiently searched at any timing of the work schedule. For example, consider a case where the misplaced place estimation unit 748 acquires the work completion information of the model B and the work A via the portable terminal 4 after the model B and the work A in FIG. Here, if the tool check is performed after the model B, the work of the model C is excluded from the work of the model C, and the work place C of the model B, which is the place where the shortage tool (tool E) is used most recently, is used as a search place candidate. Just output.

  In this way, for example, when the operator 3 misplaces a tool after the end of a predetermined work, the place where the missing tool was last used should be extracted from the work schedule recorded in the work schedule recording unit 703 and searched. By notifying the operator 3 of the location, it is possible to support efficient search for a missing tool.

  The second embodiment uses image information obtained by the camera 2 in addition to the configuration described in the first embodiment. Normal shooting time information is added to the image information. In the second embodiment, paying attention to the shooting time information, when the missing tool is actually extracted from the image, the missing tool exists in the range where the shooting time of the image at the time of extraction reaches at least the eye of the operator 3. Take advantage of the time. The system configuration of the second embodiment is the same as that of the first embodiment shown in FIG. 2 unless otherwise specified. In the second embodiment, as in the first embodiment, the tools used on the day are the tools A, B, D, E, and F, and the case where the tool E is left behind will be described.

  FIG. 7 is a conceptual diagram illustrating a method for estimating a place where a missing tool is left behind in the second embodiment, and illustrates how time progresses from top to bottom. In the second embodiment, in addition to the model, work, and work place, a work schedule in which time information for starting work at each work place is entered in advance is used. Further, since the case where the tool check is performed at the end of the work B of the model A is shown, the work schedule after the model B is omitted in FIG.

FIG. 8 is a diagram illustrating an example of a missing tool search flow by the misplaced place estimation unit 748 in the second embodiment, and corresponds to step S606 in FIG. 6 in the first embodiment. The search location estimation flow will be described with reference to FIG.
First, the missing tool information (here, specifically, the missing tool will be described as the tool E. The same applies to the following embodiments) is acquired (S801). Here, the extraction timing of the shortage tool is assumed to be at the end of the work of the model A in the second embodiment.
Next, as shown in FIG. 7 as the search direction 71 of the tool E from the image recorded in the image recording unit 705, the time when the insufficient tool is extracted is traced back to the past (in reverse order of time series). Images are extracted in order (S802).

  Then, from the image extracted in step S802, the tool extraction unit 728 confirms whether or not the tool E that is an insufficient tool has been recognized (S803). When there are a plurality of missing tools, it is only necessary to confirm whether or not each of the plurality of missing tools is recognized on the image. Next, when the tool E is recognized in step S803 (YES in S803), the shooting time is extracted from the image, and the work place at the shooting time is extracted from the work schedule (S804). Note that the recognition of the tool E in step S803 is shown as the tool E closest recognition 72 in FIG.

  In the case of FIG. 7, since the tool E latest recognition 72 is between 10:00 and 10:30, the work place C is extracted. In addition, considering the possibility that the work will not proceed according to the work start time described in the work schedule, the work place in the work before and after the work in the extracted model A, work A, and work place C is also searched. The work place B may also be estimated as a second place candidate. In the case of the second embodiment, since the work immediately after the work place C of the work A is also the work place C, the work place B that is the work place immediately before the work place C of the work A may be output together.

In FIG. 7, in order to explain the image, the case where the tool E is recognized is also displayed in the image in the time zone before the tool E latest recognition 72, but it is sufficient that at least the latest image can be extracted. Therefore, it is not necessary to perform image recognition in the time zone before the tool E latest recognition 72.
However, if there is an error in the recognition of the image of the tool E closest recognition 72, an image in which the tool E is recognized next to the tool E closest recognition 72 may be further extracted. Further, the order of images for recognizing the tool E does not necessarily have to be traced back from the present to the past. If the processing capacity of the time and the control unit 707 is sufficient, the presence / absence of recognition of the tool E is checked in time series. Then, the tool E latest recognition 72 may be extracted.

  As described above, in the second embodiment, by using the work schedule to which the time information is added and the image information, it is possible to accurately suggest the time and place where the missing tool was actually last.

  The third embodiment is an example in which elevator control information is further used in addition to the configuration described in the first embodiment. By using the control information of the elevator, the place where the worker 3 was actually working can be estimated more accurately based on the content of the control information and the acquisition time. The third embodiment pays attention to the above points, and enables the worker to be more accurately supported for searching for misplaced tools. In the third embodiment, as in the second embodiment, the system configuration is the same as that of the first embodiment shown in FIG. 2 unless otherwise described, and the situation is described assuming that the tool E is left behind.

  FIG. 9 is a conceptual diagram showing a method for estimating a place where a missing tool is left behind in the third embodiment. As in FIG. 7, the time progresses from top to bottom. In the recognized tool 91 column, the tool recognized by the tool extraction unit 728 from the images taken by the camera 2 among the tools A to F is indicated by a black circle. For example, when taking an image of the entire tool at the confirmation 94 before departure from the sales office, all tools (tools A, B, D, E, and F) used on the day are recognized if there is no forgetting to take out or there is no mistake. Is done.

The column of the acquired elevator control information 92 indicates that there is elevator control information input to the elevator control device 5 with black triangle marks.
These pieces of information are recorded together with the input time information in the control information recording unit 706 of the monitoring device 7 shown in FIG. As the control information, for example, maintenance switch on / off information, car control information, information on door opening / closing, and the like can be considered.

  In the column of the estimated work place 93, the work place of the worker 3 estimated by the work place estimation unit 768 based on the elevator control information 92 is shown. By acquiring the elevator control information 92 according to the location where the control command can be issued and the control command content, for example, whether the worker 3 is in the machine room, has entered the pit below the hoistway, is on the car, etc. Can be estimated.

  The work location estimation process is performed in advance by a control unit (not shown) in the elevator control device 5, and the estimation result is transmitted to the work location estimation unit 768 of the monitoring device 7. May be recorded in the control information recording unit 706 together with the time information when the control information is acquired.

FIG. 10 is a diagram illustrating an example of a missing tool search flow by the misplaced place estimation unit 748 in the third embodiment, and corresponds to step S606 in FIG. 6 in the first embodiment. The search location estimation flow will be described with reference to FIG.
First, missing tool information is acquired (S1001). FIG. 9 shows that only the tool E is not recognized in the tool check performed at the end of work 98 of the model C, and is extracted as a missing tool.

  Then, a work place (work place C) using the tool E, which is a missing tool, is extracted from the work schedule for that day (see FIG. 4) (S1002). Next, the time zone in which the worker 3 was at the work place C extracted in step S1002 is extracted using the elevator control information recorded in the control information recording unit 706 (S1003). In the case of the tool E, the time zone of “model C work place C” at the estimated work place 93 in FIG. 9 is extracted. Then, an image captured in a time zone between the work start time 96 at the work place C of the model C in FIG. 9 and the work end time 98 of the model C is selected as the tool E search range 99 (S1004).

  Further, the tool E is recognized with respect to the image of the camera 2 photographed in the time zone of the tool E search range 99, the tool E final recognition 97a that is the image in which the tool E is finally recognized is extracted, and the tool E The last recognized time 97 is calculated. In this way, by narrowing down the tool E search range 99, the trouble of searching for the tool E from all the images recorded on the image recording unit 705 can be saved, so that the tool E can be extracted efficiently.

  If it is highly likely that the tool E has been misplaced in the work place C of the model C, an image is extracted from the images of the model C, the work place C, and the work start time 96 in chronological order, and the tool E is searched. Good. Thereby, it is possible to more reliably search for a place where the tool E is left behind in an order from an image in which the tool E is recognized. Further, when searching only for the time zone at the work place C, the tool E is identified by tracing the image from the last time at the model C work place C to search for the tool E final recognition 97a. You can search quickly. In addition, when there is time allowance, the place where the missing tool is left behind may be estimated from the image of the entire time zone and the elevator control information 92 without using the work schedule.

  Finally, the work place where the worker 3 was actually present is extracted from the estimated work place 93 at the time 97 when the tool E is recognized (S1006). In FIG. 9, the work place A of the model C, which is the work place where the worker 3 was, is extracted at the time 97 when the tool E is finally recognized. As in the first embodiment, at least the search is performed by presenting the work place by the estimated work place 93 for each of a plurality of images in which the tool E is recognized as well as when the tool E is last recognized. The place can be narrowed down, and the effect of quicker search support for missing tools can be achieved.

Similarly to the first embodiment, when the tool E is finally recognized, all work places that have been worked up to the present time are estimated as search candidates, and there is no tool at the last recognized work place. In addition, an efficient search for the tool E can be supported.
As described above, in the third embodiment, even when a tool is misplaced in a place different from the work place where the missing tool is used, it is possible to search the misplaced place accurately and provide search support to the worker 3. Become.

FIG. 11 is a diagram illustrating a notification example when there is a missing tool. In the case of the second embodiment and the third embodiment, the shortage tool, the photographing time and the image of the last recognized image of the missing tool, and the location where the worker 3 was at the last recognized time of the missing tool are portable terminals. 4 is displayed. Thereby, the operator 3 can confirm the candidate of the misplaced place of the tool E, and can expect an earlier search for the tool E. In the case of the first embodiment, only the missing tool and the expected misplacement are displayed.
The display may be displayed on another display device (not shown) in the monitoring center where the monitoring device 7 is located, and the monitoring person in the monitoring center may inform the operator 3 of the candidate for the misplaced place.

  The fourth embodiment is a site where the mobile terminal 4 has some functions of the monitoring device 7 in the first embodiment, thereby reducing the communication cost between the mobile terminal 4 and the monitoring device 7 and having a poor communication environment. Can also support the search for missing tools.

FIG. 12 is a block diagram illustrating a system configuration example according to the fourth embodiment. Note that both the portable terminal 4 and the monitoring device 7 are omitted for the control unit. The same components as those in FIG. 2 are denoted by the same reference numerals.
As illustrated in FIG. 12, the mobile terminal 4 includes a communication unit 401, a memory 402, a work schedule recording unit 403, a tool recording unit 404, an image recording unit 405, and a display unit 406.
The memory 402 includes a tool extraction unit 412, a comparison unit 422, a misplaced place estimation unit 432, a result output unit 442, and a work place estimation unit 452.
On the other hand, the monitoring device 7 in FIG. 12 is configured to include only the communication unit 701, the work-specific tool recording unit 702, the control information recording unit 706, and the memory 708.
