  In general, product development is evaluated based on the specifications of the developed product, and the analyst analyzes and corrects / improves the failure found in the evaluation. Yes. In that process, when the evaluation operator finds an operation different from the specification for the product developed at the time of evaluation, the evaluation operator describes the operation procedure / occurrence frequency in which the phenomenon or phenomenon has occurred in the failure slip. A log output by the product under test may be attached to the failure slip. The analyst predicts the operation causing the failure based on the failure slip described by the evaluation worker and the information and experience of the log output by the evaluation target, and reproduces the failure. After establishing the procedure to reproduce the fault, the actual cause is investigated. When reproducing this fault, for example, it may occur due to external factors and environments that are not recorded in the log, such as `` There is a difference between the amount of light at the time of exposure and the amount of light at the time of exposure, and the imaging becomes white ''. In the case of a failure, it took a lot of effort and time to reproduce the failure. As a method for solving such a problem, a method of photographing an operator's work situation is one of effective means. Patent Document 1 is known as a known technique of a method for photographing an operator's work situation.

  FIG. 24 is a flowchart for explaining processing after a user reports a failure from the failure report transmission unit 1028 and receives the report by the failure report reception unit 1029 of the user terminal 1027.

  When the failure report receiving unit 1029 receives the failure report, the user terminal 1027 acquires the evaluation ID from the evaluation ID storage unit 1032 (S2401) (24000). Next, the user terminal 1027 acquires the current date and time (S2402). The user terminal 1027 logs in to the failure management server, and when logged in, the user terminal 1027 transmits the acquired evaluation ID and current date and time to the failure management server via the network using the HTTP protocol (S2403) (S2404). If login to the failure management server has not been performed, a login screen is displayed and login is performed (S2403) (S2405).

  FIG. 25 is a flowchart for explaining the flow of processing in the failure management server 1001 after receiving a failure report from the user terminal 1027.

  When a failure report is transmitted from the user terminal 1027, the control unit 1010 receives the transmission content via the communication interface in the failure management server 1001. The control unit 1010 acquires an evaluation ID from the transmitted content (S2501). The control unit 1010 acquires a failure report time from the transmitted contents (S2502). The control unit 1010 issues a failure form screen creation request to the failure form screen display unit 1011 using the acquired evaluation ID and failure report time as arguments (S2503). Upon receiving the request, the trouble ticket display unit 1011 displays a trouble ticket edit screen (S2504).

  FIG. 26 is a flowchart for explaining the flow of processing in which the failure slip screen display unit 1011 that receives the request displays the failure slip screen.

  Upon receiving the request, the failure slip screen display unit 1011 issues a failure slip creation request to the failure slip creation means 1012 with the evaluation ID and the failure report time as arguments. Upon receiving the request, the trouble ticket creating unit 1012 acquires the state of the trouble ticket. At the time when the failure report is received, the failure slip is in an evaluation state. Therefore, a failure slip operation procedure column creation request is issued to the operation procedure registration means using the failure report time as an argument (S2601) (S2602). If the failure slip is in the state transition from the evaluation state to the analysis state, S2602 is skipped and the next step is performed. The failure slip creation means 1012 issues a failure analysis screen creation request to the failure analysis screen display means 1014 with the evaluation ID and the failure report time as arguments (S2603). The failure slip creation unit 1012 receives the failure analysis screen creation result from the failure analysis screen display unit 1014 and displays the failure slip edit screen (S2604). The trouble ticket creating means 1012 checks whether or not the video needs to be reproduced (S2605). When it is necessary to reproduce the video, the trouble ticket creation unit 1012 issues a video reproduction request to the video reproduction unit 1021 using the reproduction start time as an argument (S2606). Upon receiving the request, the video playback unit 1021 performs streaming playback of the video from the playback time via the streaming server (S2607).

  FIG. 27 is a flowchart for explaining the flow of processing in the failure analysis screen display means 1014 that has received a failure analysis screen creation request from the failure slip screen creation means 1012.

  When the failure analysis screen display unit 1014 receives a failure analysis screen creation request from the failure slip screen creation unit 1012, the failure analysis screen display unit 1014 issues a log output range acquisition request to the log output range control unit 1004 (S2701). The failure analysis screen display unit 1014 issues a log output type acquisition request to the log output type control unit 1005 (S2702). The failure analysis screen display means 1014 issues an output log type designation means creation request to the output log type designation means 1020 using the acquired log output type as an argument (S2703). The failure analysis screen display unit 1014 issues a creation request to the video display unit using the acquired log output range as an argument (S2704). The failure analysis screen display means 1014 issues a creation request to the video playback location designation means 1019 using the acquired log output range as an argument (S2705). The failure analysis screen display means 1014 issues a log output status display means creation request to the log output status display means 1015 using the log output range and the log output type as arguments (S2706). The failure analysis screen display means 1014 issues a log output range designation means creation request to the log output range designation means 1017 using the log output range as an argument (S2707). The failure analysis screen display unit 1014 checks whether the analysis button on the failure analysis screen is pressed using the parameters in the request transmitted from the user terminal 1027 through HTTP communication (S2708). When the analysis button is pressed, the failure analysis screen display unit 1014 issues an analysis result display request to the log analysis result display unit 1016 using the analysis result as an argument (S2709). The failure analysis screen display unit 1014 determines whether or not the log of the log output status display unit 1015 is designated using the parameters in the request transmitted from the user terminal 1027 through HTTP communication (S2710). When the log is designated, the failure analysis screen display unit 1014 displays the evaluation target operation log associated with each frame of the moving image being displayed / played using the output time of the designated log as an argument. A display request is issued to the log display means (S2712). If no log is specified in the check in step 2710, the failure analysis screen display unit 1014 checks whether the range of the output log is the minimum (S2711). If the log output range is the minimum in the check in step 2711, the process in step 2712 is performed.

  FIG. 28 is a flowchart illustrating the processing flow of the log output range control unit 1004 after receiving a log output range acquisition request from the failure analysis screen display unit 1014.

  Upon receiving the log output range acquisition request from the failure analysis screen display unit 1014, the log output range control unit 1004 checks whether the state of the failure vote is an evaluation state or an analysis state (S2801). When the failure slip state is the analysis state, the log output range control unit 1004 checks whether the log output range is specified by the log output range specifying unit 1017 from the request parameter (S2802). When the log output range is not specified by the log output range specifying unit 1017, the log output range control unit 1004 checks whether the analysis button on the failure analysis screen or the analysis result link is pressed using the parameter in the request (S2803). ). When the analysis button on the failure analysis screen or the analysis result link is not pressed, the log output range control unit 1004 checks whether the link displayed by the log output status display unit 1015 has been pressed by using the parameter in the request. (S2804). When the link displayed by the log output status display unit 1015 is not pressed, the log output range control unit 1004 acquires the phenomenon range managed in the failure slip management table (S2805) (28000). The log output range control unit 1004 sets the start position and end position of the acquired phenomenon range as the log output range and returns them to the failure analysis screen display unit 1014 (S2806). When the log output range is specified by the log output range specifying unit 1017 in the check of S2802, the log output range control unit 1004 sets the specified range as the log output range and returns it to the failure analysis screen display unit 1014 (S2807). When the analysis button on the failure analysis screen or the analysis result link is pressed in the check in S2803, the log output range control unit 1004 uses the failure slip ID of the failure slip that is currently displayed from the failure slip management table 1025, and the phenomenon range. Is acquired (S2815). The log output range control unit 1004 sets the log output range from the recording start position of the evaluation situation photographed moving image to the end position of the phenomenon range and returns it to the failure analysis screen display unit 1014 (S2818). When the link displayed by the log output status display unit 1015 is pressed in step 2804, the log output range control unit 1004 checks whether it is specified which operation goes back from the specified log (S2813). If it is specified which operation goes back from the specified log, the operation from the specified operation to the specified log is returned to the failure analysis screen display means 1014 as the log output range (S2814). When it is not specified which operation goes back from the log specified in the check in step 2813, the log output range control unit 1004 acquires a predetermined retroactive time or the number of retroactive operations (S2815). The log output range control unit 1004 returns to the failure analysis screen display unit 1014 the log output range from the portion corresponding to the acquired retroactive time or the number of retroactive operations to the specified log. If there is no designation to go back, it is possible to go back to an external input operation such as pressing a button just before (S2816). If it is determined in step 2801 that the failure form is in the evaluation state, the log output range control unit 1004 checks whether the log output range is specified by the log output range specifying unit 1017 from the request parameter (S2808). When the log output range is specified by the log output range specifying unit 1017, the specified range is set as the log output range and returned to the failure analysis screen display unit 1014 (S2809). When the log output range is not specified by the log output range specifying unit 1017 in the check in step 2808, the log output range control unit 1004 checks whether the start / end position of the phenomenon range is registered in the failure slip management table 1025 ( S2810) When the start / end position of the phenomenon range is registered in the failure slip management table 1025, the log output range control unit 1004 sets the log output range from the start position to the end position of the acquired phenomenon range (S2811). When the start / end position of the phenomenon range is not registered in the failure slip management table 1025 in the check of step 2810, the log output range control unit 1004 goes back to the location that is back by the number of external input logs defined in advance from the failure report time. Is output to the failure analysis screen display means 1014 (S2812).

  FIG. 29 is a flowchart illustrating the processing flow of the log output type control unit 1005 that has received the log output type acquisition request from the failure analysis screen display unit 1014.

  When the log output type control unit 1005 receives the log output type acquisition request from the failure analysis screen display unit 1014, the log output type control unit 1005 checks whether the output log type designation unit 1020 has specified the type of the output log using the parameters in the request (S2901). . When the output log type designation unit 1020 has not designated the type of the output log, the log output type control unit 1005 checks whether the status of the failure vote is an evaluation state or an analysis state (S2902). If the state of the failure vote is the analysis state, the log output type control unit 1005 returns it to the failure analysis screen display unit 1014 as a log to be output from the external input / output log (S2903). If the output log type designation unit 1020 designates the output log type in the check at step 2901, the log output type control unit 1005 returns the designated log type as an output log to the failure analysis screen display unit 1014 ( S2905). If it is determined in step 2902 that the status of the failure vote is an evaluation status, the external input log is returned to the failure analysis screen display means 1014 as a default log (S2904).

  FIG. 30 is a flowchart illustrating a flow of processing in which the video display unit receives a creation request from the failure analysis screen display unit 1014 and determines a representative frame to be displayed when the video to be played back is stopped.

  When the image display means receives the creation request from the failure analysis screen display means 1014, the log output range passed as an argument is compared with the phenomenon range registered in the failure slip (S3001). As a result of the comparison, if the phenomenon range matches the log output range, the video display means extracts the final external output log within the failure phenomenon range (S3002). The video display means extracts a frame associated with the extracted external output log (S3003). The video display means determines that the extracted frame is a representative frame to be displayed when stopped, and displays the extracted frame (S3004). If the phenomenon range does not match the log output range in step 3001, the video display means extracts a frame in the moving image corresponding to the start time of the log output range (S3005). The video display means determines that the extracted frame is a frame to be displayed when stopped, and displays the extracted frame (S3004).

  FIG. 31 is a flowchart for explaining the processing up to the creation of an image / chapter for designating the video playback location of the video playback location designating means 1019 that has received the creation request from the failure analysis screen display means 1014.

  When receiving the creation request with the log output range as an argument from the failure analysis screen display unit 1014, the video playback location designation unit 1019 acquires the maximum value of the chapter / image to be displayed on the failure analysis screen (S3101). The video playback location designation means 1019 calculates the playback range of each chapter by dividing the log output range passed by the argument by the maximum number of display chapters (S3103). The video playback location specifying means 1019 extracts a frame corresponding to the playback range from the video (S3104). A frame associated with the external input / output log is extracted in the meta information of each extracted frame (S3105). The processing from step 3103 to step 3105 is performed for the maximum value of the chapter (S3102). The video playback location specifying means 1019 plays back only the frame associated with the external input / output log extracted within the playback range of each chapter as a moving image (S3106).

  FIG. 32 is a flowchart for explaining the flow of processing of the operation procedure registration unit 1013 that has received the creation request from the failure slip screen creation unit.

  When receiving the creation request from the failure slip screen creation means, the operation procedure registration means 1013 checks whether the operation procedure is registered in the failure slip management table 1025 (S3201). When the operation procedure is registered in the failure slip management table 1025, the operation procedure registration unit 1013 extracts the operation procedure from the failure slip management table 1025 (S3202) (32000). The operation procedure registration unit 1013 extracts a display name corresponding to the extracted operation procedure from the external input log name management table 1026 (S3203). The operation procedure registration unit 1013 displays the extracted operation procedure display name in the operation procedure column of the failure slip screen (S3204). When the operation procedure is not registered in the failure slip management table 1025 in the check of step 3201, the operation procedure registration unit 1013 checks whether the phenomenon range is registered in the failure slip management table 1025 (S3205). When the phenomenon range is registered in the failure slip data management table 1025, the start position and end position of the phenomenon range are extracted from the failure slip management table 1025 (S3206). The operation procedure registration unit 1013 extracts frames in the moving image corresponding to the start position and end position of the extracted phenomenon range, and extracts external input logs such as button operations from the logs associated with the extracted frames. (S3207). The display name of the extracted external input log is acquired from the external input log name management table (S3208) (32003). The operation procedure registration unit 1013 arranges the extracted external input log display names in ascending order of output times and displays them in the operation procedure column of the failure slip screen (S3209). When the phenomenon range is not registered in the failure slip management table 1025 in the check in step 3205, the operation procedure registration unit 1013 extracts the external input log within the log output range (S3210). The operation procedure registration unit 1013 extracts the display name of the external input log corresponding to the extracted external input log from the external input log name management table (S3211) (32004). The operation procedure registration means 1013 arranges the extracted external input display names in ascending order at the output time and displays them in the operation procedure column of the failure slip (S3212).

  The flow of processing from the trouble report to the creation of the trouble ticket has been described with reference to FIGS.

  FIG. 33 is an example of a failure slip edit screen in the first embodiment according to the present invention.

The failure slip editing screen 3300 includes a field 3301 for displaying the failure slip ID on the failure slip editing screen displayed after the evaluator reports the failure, a state field 3302 for displaying the state of the current failure slip, and the current failure slip. A person-in-charge field 3303 for displaying a person in charge, a field 3305 for designating an output log in a check box format, a video display field 3306 for reproducing a video in which video is designated, and a chapter from a video file in a designated log output range are displayed. The video playback location designation field 3307 generated and displayed, and the output status of the log designated in the field 3308 showing the playback start time of the chapter and the output log designation field 3305 are displayed in time series in each chapter. Log output status display field 3310 and log output status field A log output range designation scroll bar 3312 for designating a range to be displayed or a chapter generation range, a field 3310 for displaying the time of the start position designated by the scroll bar, and a field for displaying the time of the end position designated by the scroll bar A playback button 3313 for playing a movie in a range designated as 3311, a stop button 3314 for stopping the played movie, a pause button 3315 for pausing the played movie, and a movie to be played are wound.

A phenomenon report field 3322 comprising an operation procedure field 3224, a field phenomenon range field 3325 for inputting a phenomenon range, a field 3326 for entering a creation date, and a field 3327 for displaying the creator of the trouble slip; It includes a save button 3328 that saves the content input to the failure slip. The output log designation field 3305 is created by the means of the output log type designation means 1020, and the display video when the video display field 3306 is stopped is determined by the video display means. In the video playback location designation field 3307, the video playback location designation means determines the playback range of each chapter and the playback method of the displayed video. Each video is a chapter that holds the playback start position, and when the image is double-clicked, the video can be played back within a predetermined playback range. The log output status display field 3310 is generated by the log output status display means 1015. In the log output status display field 3310, the output location is indicated by a line, and the line is a link. When the link is pressed, the detailed log output status is displayed from the current status around the specified log. The detailed output log around the specified location is also displayed. The log output range designation scroll bar 3312 defaults from the failure report time to a predetermined location at the time of failure reporting, and can be designated by the user thereafter. By moving the scroll bar and changing the log output range, the log output status result and chapter playback range dynamically change. The phenomenon range field may be input directly, or by selecting an image in the video reproduction location designation field, the reproduction range of the selected image can be dynamically input as a phenomenon range. When a plurality of selections are made, the playback start time and playback end time of the selected chapters may be arranged in ascending order and the first and last times may be input to the phenomenon range. Further, by selecting a log output status link, the output times of the selected logs may be arranged in ascending order so that the first and last ones can be dynamically entered in the phenomenon range column. As a fast-forward method of the fast-forward button 3317, fast-forwarding may be performed as usual, or a part (evaluation by an evaluator such as a button press) associated with an external input log using an operation log to be evaluated associated with moving image data. You can fast-forward only the location where the operation was performed on the target), or the location that is associated with the external output log (screen display, etc., as a result of the evaluator performing an operation on the evaluation target) (The output in a form that can be recognized) may be fast-forwarded, or only the frames that are externally input and output may be shown. The rewind button 3316, the frame advance button 3319, the frame rewind button 3318, the next chapter transition button 3321, and the previous chapter transition button 3320 may be operated in consideration of the external input and the external output similarly to the fast forward button 3317. . When the save button 3228 is pressed, a failure slip display screen is displayed. FIG. 34 is a flowchart for explaining the flow of processing from when the failure slip save button is pressed until the input value is stored in the failure slip management table 1025. is there.

  When the control unit 1010 receives the failure form storage request, the control unit 1010 acquires the state of the failure form and checks whether the state of the failure form is an evaluation state or an analysis state (S3401). When the state of the failure vote is the evaluation state, the control unit 1010 issues a phenomenon range specifying request to the phenomenon range specifying unit 1008 (S3402). The control unit 1010 registers the contents entered in the failure slip and the phenomenon range specified by the phenomenon range specifying means 1008 in the failure slip management table 1025 (S3403) (34000). The control unit 1010 issues a failure voucher saving screen creation request (S3404). The failure slip screen creation means displays a failure slip storage screen (S3407). If it is determined in step 3401 that the status of the failure slip is an analysis state, a cause location specifying request is issued to the cause location specifying means 1009 (S3405). The control unit 1010 registers the information entered in the failure slip, the cause location, and the failure slip management table 1025 (S3406) (34001).

  FIG. 35 is a flowchart for explaining the flow of processing of the phenomenon range specifying means.

  The phenomenon range specifying unit 1007 checks whether an operation procedure is entered (S3501). The phenomenon range specifying unit 1007 extracts the entered start procedure and end procedure (S3502). The phenomenon range specifying unit 1007 extracts the times of the extracted start procedure and end procedure (S3503). The elephant range specifying unit 1007 sets the extracted start procedure time as the start time of the phenomenon range and the end procedure time as the end time (S3504). If the operation procedure is not entered in the check in step 3501, the phenomenon range specifying unit 1007 checks whether a chapter image is selected (S3505). If it is selected, the phenomenon range specifying unit 1007 extracts the start time of the selected chapter (S3506). The phenomenon range specifying unit 1007 arranges the extracted times in ascending order of time series, and sets the first and last positions as the start position and end position of the phenomenon range (S3507). When no chapter image is selected in the check in step 3505, the phenomenon range specifying unit 1007 sets the log output range specified in the failure slip as the phenomenon range (S3508).

  FIG. 36 shows an example of the failure slip display screen in the evaluation state of the failure slip.

  The failure slip display screen 3600 includes an edit button 3602 for transition to the failure slip edit screen, a button menu button 3602 for transition to the menu screen, and the display state field of the field described in the failure slip edit screen 3300.

  The configuration of the trouble ticket edit screen 4200 is omitted because it has already been described with reference to FIGS.

  In the trouble ticket edit screen 4200, the designated chapter is surrounded by a thick line so that it can be clearly seen that it has been designated. In addition, a chapter is regenerated with the playback range of the specified chapter as the log output range, and the log output status is displayed according to the range. A log output range designation scroll bar 3312 is also displayed in the designated range. A moving image is played back in the video display field from the playback start position of the designated chapter.

  FIG. 43 is a flowchart illustrating the playback location determination means 1019 for determining the playback location when a video playback request is made.

  The playback location determination means 1019 checks whether the playback button has been pressed (S4301). When the playback button is pressed, the playback location determination unit 1019 acquires the designated log output range (S3402). The playback location determination means 1019 sets the acquired log output range as the playback range, and sets the beginning of the log output range as the playback location (S3403). If the playback button has not been pressed in step 4301, the playback location determination means 1019 checks whether the chapter image has been pressed from the parameters in the request (S4304). If the chapter image has not been pressed, the playback location determination unit 1019 checks whether the log output status screen has been pressed (S4305). If the log output status screen has been pressed, the playback location determination means 1019 acquires the pressed log type (S4306). The reproduction location determination means 1019 checks whether the retroactive location and time are defined in advance for the extracted log (S4307). If it has been registered, the playback location determination means 1019 sets the registered retroactive location as the playback location (S4313). If it is not registered in step 4307, the reproduction location determination means 1019 checks the status of the failure slip (S4308). If the state of the failure vote is the evaluation state, the reproduction location determination unit 1019 sets the external input log immediately before the designated log as the reproduction location (S412). If the state of the failure vote is the analysis state in step 4308, the reproduction location determination means 1019 extracts the external output log immediately before the designated log (S4309). The reproduction location determination unit 1019 extracts a frame associated with the extracted external output log (S4310). The playback location determination means 1019 sets the extracted frame as the playback location (S4311).

  FIG. 44 shows an example of the failure slip editing screen when the link of the log output status display field is pressed from the failure slip editing screen after designating the chapter of FIG.

  The configuration of the trouble ticket edit screen 4400 is omitted because it has already been described with reference to FIGS.

  The selected log is displayed in the frame related log display field of the failure slip editing screen 4400 so that the selected log can be clearly seen, and the log output before the designated log is displayed. Also, the output status of the surrounding logs is displayed with the specified log output time as the start position of the log output range. Chapters are also generated according to the output status. A log output range designation scroll bar 3312 is also displayed in accordance with the designated range. The moving image is played back in the video display field 3306 with the frame associated with the designated log as the playback location.

  When the save button on the trouble slip edit screen is pressed, the screen shifts to the trouble slip display screen.

  FIG. 45 shows an example of a failure slip display screen when the failure slip state after the save button is pressed is in the analysis state.

  The configuration of the failure ticket display screen 4500 is omitted because it has already been described with reference to FIGS.

  FIG. 46 is a flowchart for explaining the processing flow of the cause location specifying means 1009.

  When the cause location specifying unit 1009 receives the cause location specifying request from the failure vote screen creation unit 1012 in step 3405 of FIG. 34, it checks whether the log of the log output status display unit is selected (S4601). If it is selected, the cause location specifying means 1009 extracts the output time of the selected log (S4602). The cause location specifying means 1009 arranges the output times in ascending order of time series, with the first being the start position of the phenomenon range and the last being the end position of the phenomenon range (S4603). When the log of the log output status is not selected in the check in step 4604, the cause location specifying unit 1009 checks whether the image of the playback location specifying unit is selected (S4604). The cause location specifying means 1009 extracts the reproduction start time of the selected image (S4605). The cause location specifying means 1009 arranges the extracted times in ascending order of time series, with the first being the start position of the phenomenon range and the last being the end position of the phenomenon range (S4606). If no image has been selected in step 4604, the cause location specifying unit 1009 sets the log output range specified in the failure slip as the cause location range (S4607).
