<Embodiment 1>
FIG. 1 is an explanatory diagram showing work images stored in the storage unit (the storage unit 31 of the management server 30 in FIG. 2). FIG. 1A shows the recording state of the work image of the comparative example, and FIG. 1B shows the recording state of the work image according to this embodiment. FIG. 1A shows a display screen of a work procedure displayed on the display device 25 installed at the work place, and a work image stored in the storage unit 31 (see FIG. 2) for a moving image of the work place. The recording state is schematically shown. When the instruction 50 including the IC tag is input to the work management box 21 where the IC tag is placed, the content of the sheet # 1 indicating the work content instruction screen is first displayed on the display device 25 according to the work procedure. Each time the operator depresses the switch 24, the contents of the sheet # 2, sheet # 3,.

  When a moving image is shot by a camera 23 (for example, a Web camera) (see FIG. 2) that is a shooting device, for example, when a frame rate of 30 fps (frame per second) is set, 30 still images are stored in the storage unit 31 per second. In the moving image, a management method using time such as a time axis or a time code is adopted. Here, a description will be given using a time code. If the time code is “00: 07: 50: 10”, it means that the display position is 0: 7: 50: 11th frame position. The frame count starts from “0”.

  When shooting is started by the camera 23 together with the start of work, the time code in the storage unit 31 is “00:00:00”, “00: 00: 00: 01”,..., “00: “00:00:29”, “00: 00: 01: 00”,..., “00: 07: 50: 10” still images (for example, JPEG (Joint Photographic Experts Group) format images) are stored. To go. In the work image recording state of FIG. 1A, the work procedure sheet # 1, sheet # 2, etc. are not associated with the work image recording state. There is a need to.

  On the other hand, with reference to FIG.1 (b), the storage method of the working image which concerns on this embodiment is demonstrated. When the instruction 50 including the IC tag is inserted into the work management box 21 where the IC tag is placed, shooting by the camera 23 which is a photographing device starts, and the management server 30 (see FIG. 2) is photographed. Image storage is started (step S100).

  Next, when the pressing of the switch 24 is detected, the management server 30 associates the sheet # 1 with the detected time and considers the elapsed time from the start of photographing, and the time code “00:00: The image of “20:00” is stored (step S101). If an image with the time code “00: 00: 20: 00” already exists, it is overwritten or replaced. Thereby, it can reproduce | regenerate as a moving image by the existing software, without time code duplication.

  Further, when the pressing of the switch 24 is detected, the management server 30 associates the sheet # 2 with the detected time, and considers the elapsed time from the start of photographing, and the time code “00:00:50”. : 0: "is stored (step S102). Similarly, an image in which sheet # 3, sheet # 4, and sheet # 5 are associated with the time when pressing of the switch 24 is detected is stored. When the pressing of the switch 24 is detected, the management server 30 associates the sheet # 6 with the detected time, and considers the elapsed time from the start of shooting, and the time code “00:07:40”. 0:00 ”is stored (step S106). Finally, when the instruction 50 is taken out from the work management box 21, the management server 30 (see FIG. 2) takes into account the elapsed time from the start of shooting and uses the time code “00: 07: 50: 10”. The image is stored (step S107), and the series of processing ends.

Then, the management server 30 displays the image associated with the sheet # 1 (for example, the sheet ID is B0001) with a time code based on the work start date and time of the instruction ID and the work end time of the sheet ID shown in FIG. The file name is stored (step S307). The sheet image to be created includes an index part and an image part representing work contents. In the index part, communication start time information that is a work start record, information for specifying the work content of the work target article, and the like are described.

  Specifically, the work start date and time is “200X / 05/10 9:00:00” (200X May 10, 9:00:00), and the work end date and time of the sheet ID B0001 is “0001”. 200X / 05/10 9:00:20 "(May 10, 200X, 9:00:20), the work time from the start of the work is 20 seconds, and the time code is" 00:00:20: 00 ”. The work start date and time is “200X / 05/10 9:00:00” (May 10, 200X, 9:00:00), and the work end date and time of the sheet ID B0004 is “200X / 05”. / 10 9:05:30 ”(9:05:30 on May 10, 200X), the work time from the start of work is 5 minutes 30 seconds, and the time code is“ 00: 05: 30: 30 Is.

  The control device 26 of the cell work terminal 20 determines whether or not all the steps of the instruction 50 have been completed (step S206). When the process is not finished (No at Step S206), the process returns to Step S203. When all the processes have been completed (step S206, Yes), the process proceeds to step S207.

  The IC tag reader / writer 22 of the cell work terminal 20 performs communication with the work specifying IC tag 51 every predetermined time, and when the communication cannot be confirmed within the predetermined time, the operator gives instructions 50 and the work management box 21. It is detected that it has been taken out from (step S207). The IC tag reader / writer 22 transmits communication end information (work end information) with the work specifying IC tag 51 to the management server 30 via the control device 26 (step S208), and ends the process.

  In step S208, the control device 26 notifies the camera 23 of the end of shooting. The camera 23 determines whether or not there is a shooting end notification (step S213), and when there is a shooting end notification (step S213, Yes), the shooting by the camera 23 ends (step S214). If it is not a shooting end notification (step S213, No), the process returns to step S212.

  When the management server 30 receives the communication end information and the information specifying the work content of the work target article from the cell work terminal 20, it adds time information (time stamp) to the received information and stores it as work end information. It records in the part 31 (step S308).

  Next, the management server 30 creates a sheet-specific folder for each sheet ID in the storage unit 31 (step S310), and sorts the captured images stored in the folder created in step S302. For example, when the instruction ID is A0001, the camera ID is C0001, and the sheet IDs are B0001, B0002,..., B0006, the folder destination path of the sheet-specific folder is e: ¥ A0001 ¥ C0001 ¥ B0001, e: ¥ A0001. ¥ C0001 ¥ B0002,..., E: ¥ A0001 ¥ C0001 ¥ B0006. The folder indicated by the path of e: ¥ A0001 ¥ C0001 ¥ B0001 includes a sheet image associated with the sheet # 1 and time codes “00: 00: 00: 00” to “00: 00: 19: 29”. A photographed image is stored. Then, a series of procedures of the photographed image management process ends. Note that a folder indicated by the path e: \ A0001 \ C0001 \ B0006, which is the last folder, includes a sheet image associated with the sheet # 6 and a time code “00: 06: 50: 01” to shooting end. It is good to store up to images.

  The captured image stored in the folder can be reproduced by an image reproduction program installed in the management server 30. Specifically, when the instruction management information 311 shown in FIG. 6 is displayed on the display device and a moving image is reproduced by clicking a predetermined area (for example, a cell having a sheet ID of B0004) with a mouse or the like, it is efficient. Work inspection can be performed.

  According to the work image management system of the first embodiment, the cell work terminal 20 includes a photographing device (for example, the camera 23), a switch 24 for instructing the operator to switch the work procedure displayed on the display device 25, and the like. An IC tag reading device (for example, IC tag reader / writer 22) that reads an IC tag in which information specifying work contents is written, which is placed in an IC tag place (for example, work management box 21), and IC tag reading When the apparatus communicates with the IC tag (has been completed), information on the start of work is transmitted to the management server 30 (step S202), and photographing of the photographing apparatus is started (step S211). Are sequentially transmitted (step S212), and when the operation of the switch 24 is detected, the management identification information (for example, sheet ID) of the work procedure and the switch 4 of the operation in association with the time of detecting transmitted to the management server 30 as a work result collection information and a (step S205) the control unit 26.

  When receiving the work start information, the management server 30 sequentially stores the captured images in the storage unit (step S305). When receiving the work result collection information, the management server 30 stores the image associated with the work result collection information in the storage unit (step S305). Step S307) The processing unit 32 is included.

  When the IC tag reader disconnects communication with the IC tag, the cell work terminal 20 transmits work end information including the time when the communication is interrupted to the management server (step S208), and the imaging device captures the image. The process ends (step S214).

<Embodiment 2>
According to the work image management system S according to the first embodiment, photographing is started when the work of the instruction is started, and photographing is finished when the work is finished. In this case, if there are many cell work terminals 20 and shooting is performed for a long time, the capacity of the captured image stored in the storage unit 31 becomes enormous. In addition, when checking the efficiency of work contents, the administrator needs to see a huge number of captured images.

  For this reason, in the second embodiment, in order to limit the photographed image, the steps of the work procedure photographed from the beginning are narrowed down based on the quality data, and the photographing is performed only when the photographing by the camera is necessary. The captured image of the process of the specific work procedure is managed. The work image management system S of the second embodiment is the same as that shown in FIG.

  FIG. 8 is an explanatory diagram showing the relationship between quality data and camera shooting. With reference to FIG. 8, the relationship between the quality data and the camera shooting and the relationship with the work record collection information recorded in the storage unit 31 will be described. When the instruction ID is A0001, the operation is started when the instruction 50 is input into the work management box 21, and the operation is completed when the instruction 50 is taken out from the work management box 21. When the instruction ID is A0002, the operation is started when another instruction 50a is inserted into the work management box 21, and the operation is completed when the instruction 50a is taken out from the work management box 21. . The details of the instruction ID A0001 are recorded in the storage unit 31 for each part assembling process (sheet ID), and include, for example, sheets # 1 to # 6.

  The storage unit 31 stores quality data managed by a quality management processing program (not shown). Specifically, the quality data is a moving average value of the number of occurrences of defects in the past N days for each process corresponding to the sheet # 1 to the sheet # 6. Based on this quality data, a setting is made to shoot with a camera when the value is equal to or greater than a predetermined value. For example, assuming that the quality data of the sheet # 3 exceeds a predetermined value, the camera shooting may be started at the start of the work of the sheet # 3, and the camera shooting may be ended at the end of the work of the sheet # 3. In the lower part of FIG. 8, the period of time taken by the camera 23 is indicated by hatching.

  FIG. 9 is a flowchart illustrating processing of the work image management system according to the second embodiment. Among the processes shown in FIG. 9, the same reference numerals are assigned to the same processes as those in FIG. The flowchart in FIG. 9 differs from the flowchart in FIG. 7 in that step S303A is different and step S209 is added. Also, based on the added step S209, the start and end of shooting by the camera 23 is processed. Differences from FIG. 7 will be described.

  After creating the folder in step S302, the management server 30 transmits the instruction information including the assembly instruction information (sheet screen corresponding to each sheet ID) of the instruction 50 to the cell work terminal 20 (step S303A). At this time, the instruction information includes a shooting flag (shooting permission / inhibition information) indicating whether or not shooting is performed for the work of the sheet ID. For example, if the shooting flag is “1” for sheet # 3 and sheet # 5 and the shooting flag is “0” for sheet # 1, sheet # 2, sheet # 4, and sheet # 6, This means that photographing is performed only in the work process of sheet # 3 and sheet # 5.

  After displaying the sheet screen in step S203, the cell work terminal 20 determines whether the photographing flag of the sheet is OK (for example, whether it is “1”) (step S209). When the flag is OK (step S209, Yes), the start of photographing by the camera 23 is notified (step S211).

  The camera 23 continues to transmit the captured image associated with the camera ID and time code to the management server 30 via the control device 26 (step S212). The management server 30 that has received the captured image stores the captured image in a predetermined folder corresponding to the camera ID (step S305).

  The control device 26 of the cell work terminal 20 determines whether or not the sheet process is finished depending on whether or not the switch 24 is pressed (pressed) (step S204), and detects the pressing of the switch 24 (step S204, Yes), the process proceeds to step S205. When the pressing of the switch 24 is not detected (No at Step S204), the process returns to Step S204.

  In step S <b> 205, the control device 26 of the cell work terminal 20 transmits information (sheet process end information) indicating that the work of the sheet process is completed to the management server 30. Specifically, the information indicating the completion of the work of the sheet process includes the instruction ID, the sheet ID, the work completion date and time, and the process ID shown in FIG.

  Further, the control device 26 notifies the camera 23 of the end of shooting. The camera 23 determines whether or not there is a shooting end notification (step S213), and when there is a shooting end notification (step S213, Yes), the shooting by the camera 23 ends (step S214). If there is no notification of the end of shooting (step S213, No), the process returns to step S212.

  According to the second embodiment, in order to limit the photographed image, the process of the photographed work procedure is narrowed down based on the quality data, and is photographed only when camera photographing is necessary. It is possible to manage the captured images of the work procedure process. In addition, although the imaging | photography flag shown to step S303A is determined based on quality data, it is not limited to this. The administrator may specify the work procedure step. For example, the manager may specify the process of the work procedure of the unskilled worker, or may specify the process of the work procedure in which the work content is switched.

  According to the work image management system of the second embodiment, the management server 30 stores shooting availability information (for example, a shooting flag) indicating whether or not to photograph the work content of the management identification information (sheet ID) of the work procedure. 31.

  The cell work terminal 20 includes a photographing device (for example, a camera 23), a switch 24 for giving a command for the operator to switch the work procedure displayed on the display device 25, and an IC tag placement location (for example, a work management box). The IC tag reader (for example, the IC tag reader / writer 22) that reads the IC tag in which the information specifying the work content is written and the IC tag reader communicates with the IC tag (see 21). If it is possible to transmit the work start information to the management server (step S202), it is determined whether or not the work content of the management identification information of the work procedure is shot based on the shooting availability information (step S209). When the result is photographed, the photographing of the photographing apparatus is started (step S211), and the photographed images are sequentially transmitted (step S212), and the operation of the switch 24 is checked. Then, the management identification information of the work procedure and the time when the operation of the switch 24 is detected are associated with each other, and the work result collection information is transmitted to the management server (step S212), and the photographing of the photographing apparatus is ended (step S214). And a processing device 26.

  When receiving the work start information, the management server 30 sequentially stores the received captured images in the storage unit (step S305). When receiving the work result collection information, the management server 30 stores the image associated with the work result collection information in the storage unit. (Step S307) The processing unit 32 is included.

  When the IC tag reader disconnects communication with the IC tag, the cell work terminal 20 transmits work end information including the time when communication is disconnected to the management server 30 (step S208).

  The shooting availability information (shooting flag) is set based on quality data relating to the work content of the management identification information of the work procedure. The quality data is, for example, a moving average value of the number of occurrences of defects in the past predetermined number of days.

  Although the present embodiment has been described using the time code in FIG. 1, it goes without saying that the captured image may be managed by the absolute time of the captured time. Even in this case, the sheet image may be inserted into the associated storage folder at the start of work, sheet switching, or work end.

  According to the present embodiment, as shown in FIG. 2, the cell work terminal 20 transmits work start information to the management server 30 when the IC tag reader / writer 22 communicates with the IC tag, and the camera The photographed images taken by 23 are sequentially transmitted. When the cell work terminal 20 detects the operation of the switch 24, the cell work terminal 20 associates the management identification information of the work procedure with the time when the operation of the switch 24 is detected, and transmits it to the management server 30 as work performance collection information. When receiving the work start information, the management server 30 sequentially stores the captured images in the storage unit, and when receiving the work record collection information, stores the image associated with the work record collection information in the storage unit. By inserting an image associated with the work record collection information in real time in the storage unit, it is possible to easily manage work images related to work contents of a plurality of processes.
