Here, edit the audio, video, still image, etc. showing the work contents, create and register work guidance content, and enable browsing of the work guidance content according to the operator's input operation, details of work for beginners In order to improve the proficiency level of the worker, acquire the time spent for the work guidance, and manage the proficiency status of the worker based on this time.
JP 2002-224922 A

  In general, an appropriate standard work time is set in advance for the product assembly work, and the worker is instructed to complete the work within the standard work time.

  However, in the above conventional system, even if the details of the work are instructed, the worker cannot know the appropriate work pace because the worker has not been informed of the progress of the standard work time. .

  If the worker is a beginner, it is difficult to finish the work within the standard work time even if the progress of the standard work time is notified. You will be conscious and can promote the proficiency of work.

  For example, it may be possible to place a watch in the vicinity of the worker so that the worker can watch the watch and grasp the progress of the work time, but it is difficult to grasp the progress of the work time while working. The work efficiency can be reduced. Therefore, it is desirable that the working pace can be easily grasped even while working.

  In addition, since the work pace varies depending on the proficiency level of the worker, it is preferable to inform the work pace according to the proficiency level of the worker.

  Therefore, the present invention has been made in view of the above-described conventional problems, and can easily grasp the work pace even while working, and can notify the work pace according to the proficiency level of the worker. The purpose is to provide a guidance system.

  In order to solve the above-described problems, the present invention is initially set as the reproduction output time of the image or sound in a work guidance system that reproduces and outputs an image or sound indicating the work content and instructs the worker to perform the work. The standard work time storage means storing the standard work time and the actual work time spent on the work are timed. When this actual work time becomes shorter than the standard work time in the standard work time storage means, the actual work time is stored. Control means for updating the reproduction output time in time.

  In addition, input means for inputting the end time of actual work is provided, and the control means counts the actual work time from the start time of the reproduction output of the image or sound to the end time of the actual work input by the input means. is doing.

  Further, the control means obtains a time difference between the standard work time and the actual work time.

  Further, a time difference storage means for storing the time difference obtained by the control means is provided.

  Furthermore, the control means stores the time difference history information in the time difference storage means.

  Further, it is possible to browse the history information of the time difference in the time difference storage means.

  Further, the control means updates the reproduction output time by changing a blank time in reproduction of the image or sound.

  According to the present invention as described above, the standard work time is initially set as the reproduction output time of the image or sound indicating the work content. For this reason, if the work is advanced according to the image or sound indicating the work content, the work can be completed in accordance with the standard work time. In addition, since the user only sees the image or listens to the sound, the working pace can be easily grasped even while working, as compared with the case where the working time is recognized by looking at the clock. Further, the actual work time spent on the work is counted, and when the actual work time becomes shorter than the standard work time, the reproduction output time is updated to the actual work time. For this reason, when the proficiency level of the worker is improved and the actual work time is shortened, the reproduction output time of the image or sound is shortened in accordance with the actual work time, and the work corresponding to the proficiency level of the worker is performed. Can inform the pace.

  Further, since the actual work time is measured from the start time of the reproduction output of the image or sound to the end time of the actual work, the actual work time can be measured only by inputting the end time of the actual work.

  Further, a time difference between the standard work time and the actual work time is obtained. In this case, it is only necessary to shorten the initially set reproduction output time by the time difference.

  Also, the time difference can be stored, or the history information of the time difference can be stored and browsed. The operator's proficiency level can be easily grasped by this time difference.

  Furthermore, the reproduction output time is updated by changing the blank time in reproduction of an image or sound.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a block diagram showing an embodiment of the work guidance system of the present invention. The work guidance system of the present embodiment includes a work guidance server 1 that plays a central role in this system, a work terminal device 2 arranged on the worker side, and a management terminal device 3 that manages the proficiency level of the worker and the like. The work guidance server 1 is connected to the work terminal device 2 and the management terminal device 3 through the network N.

  Here, although one work terminal device 2 is shown, a plurality of work terminal devices are connected to the work guidance server 1 through the network N, and any work terminal device is the same as the work terminal device 2. Is performed. Data communication between the server and the terminal device is performed according to TCP / IP.

  The work guidance server 1 and the work terminal device 2 are configured as shown in FIG. The work guidance server 1 includes a work guidance system control unit 11, a storage unit 12, a data transmission unit 13, and a data reception unit 14.

  The data transmitting unit 13 and the data receiving unit 14 are for transmitting and receiving various data to and from the work terminal device 2 and the management terminal device 3.

  The work guidance system control unit 11 is for managing and controlling the work guidance server 1 in an integrated manner. The work guidance system control unit 11 reads and executes a program from the storage unit 12 and writes and reads data to and from the storage unit 12.

  The storage unit 12 stores various programs and data used by the work guidance system control unit 11. For example, a work guidance data table 15 that stores document data, image data, and audio data indicating work contents, a standard work time table 16 that stores standard work hours spent on work, and actual work actually spent on work A time difference table 17 for storing a time difference derived from time is stored.

  In the work guidance data table 15, as shown in FIG. 3, for each model name of the product, each work number indicating a plurality of work for assembling the product, each document data indicating each work content, each image data And the respective audio data are stored in association with each other. The document data indicates a document that explains the details of the work. The image data indicates a moving image or a plurality of still images (hereinafter referred to as images) that sequentially represent work contents. The sound data indicates sound for sequentially explaining the work contents.

  In the standard work time table 16, as shown in FIG. 4, for each product model name, each work number indicating a plurality of work for assembling the product, each standard work time spent for each work, and each work Are stored in association with each date on which. The standard work time is a standard work time spent for work. If the proficiency level of the worker improves, the actual actual work time becomes shorter than the standard work time.

  The time difference table 17 is assigned to each of a plurality of workers, and the same number as the number of workers is created. As shown in FIG. 5, the time difference table 17 is assigned with the worker ID to which the time difference table 17 is assigned. Further, in this time difference table 17, for each product model name, each work number indicating a plurality of work for assembling the product, each time difference derived from the actual work time of each work, and each work Are stored in association with each date on which. The time difference is obtained by subtracting the standard work time from the actual work time only when the actual work time of the work is shorter than the standard work time of the work. Further, when the actual work time is equal to or greater than the standard work time, the time difference is set to zero. Therefore, when the proficiency level of the worker improves and the actual work time becomes shorter than the standard work time, a time difference between the actual work time and the standard work time is set, and the worker is a beginner and the actual work time If the time is equal to or greater than the standard work time, the time difference is set to zero.

  On the other hand, as shown in FIG. 2, the work terminal device 2 includes a display unit 21 for displaying various data, an input operation unit 22, a foot switch 23 operated by a worker's foot, and a control unit 24. I have.

  This work terminal device 2 is a personal computer, and as shown in FIG. 6, a control unit 24 is arranged below the work table 25 to control the display unit 21, an input operation unit 22 such as a mouse, and a foot switch 23. Connected to the unit 24. The worker performs product assembly work on the work table 25, looks at the display on the display unit 21, and operates the input operation unit 22 and the foot switch 23.

  The management terminal device 3 shown in FIG. 1 is also a personal computer, and includes a display unit, an input operation unit, and the like.

  In the work guidance system having such a configuration, when the worker performs product assembly work, document data, image data, and audio data indicating the work content are transmitted and received from the work guidance server 1 to the work terminal device 2, A document indicated by the document data or an image indicated by the image data, that is, a document or image indicating the work content is displayed on the display unit 21 of the work terminal device 2, or a sound indicated by the sound data, that is, a sound indicating the work content is displayed. It is reproduced from a speaker (not shown) of the operator terminal device 2. At this time, a document indicating the work content is displayed at an appropriate timing, and an image and sound indicating the work content are displayed and reproduced while spending an appropriate work time for the worker. For this reason, the worker can read the document representing the work content, know the work content in detail, or proceed with the work according to the image or sound, and can finish the work in accordance with an appropriate work time.

  Next, the process for work guidance by the work guidance system will be described with reference to the flowchart of FIG.

  First, the worker operates the input operation unit 22 of the work terminal device 2 to input his / her worker ID, and transmits this worker ID to the work guidance server 1 through the network N.

  The work guidance server 1 inquires the host server through the network N about the production plan for the day, and acquires the model name of the product to be assembled (step S101). The work guidance system control unit 11 refers to the standard work time table 16 in the storage unit 12 and reads each work number 1 to n and each standard work time t1 to tn in the acquired model name (step S102).

  Further, the work guidance system control unit 11 receives the worker ID from the work terminal device 2 through the data receiving unit 14, searches the storage unit 12 for the time difference table 17 to which the worker ID is assigned, and this worker. With reference to the time difference table 17 to which the ID is assigned, each work number 1 to n and each time difference Δt1 to Δtn in the acquired model name are read (step S103).

  The work guidance system control unit 11 reads each work number 1 to n and each standard work time t1 to tn read from the standard work time table 16 and each work number 1 read from the time difference table 17 to which the worker ID is assigned. ˜n and time differences Δt1 to Δtn are obtained, the standard work time and the time difference are associated with each work number, and the time difference is subtracted from the standard work time to obtain the actual work time of the worker ( Step S104). As described above, when the actual work time is shorter than the standard work time, a time difference is obtained by subtracting the standard work time from the actual work time. When the actual work time is greater than the standard work time, the time difference is calculated. Since it is set to 0, the actual work time equal to or less than the standard work time can be obtained by subtracting the time difference from the standard work time. For example, for work number 1, the actual work time T1 of the worker is obtained by subtracting the time difference Δt1 from the standard work time t1. For other work numbers 2 to n, the actual work times T2 to Tn of the worker are also obtained. And each work number 1-n and each real work time T1-Tn of an operator are matched.

  Further, the work guidance system control unit 11 refers to the work guidance data table 15 in the storage unit 12, and each work number 1 to n, each document data dt1 to dtn, each image data dg1 to dgn and audio data ds1 to dsn are read out.

  Then, the work guidance system control unit 11 stores each work number 1 to n, each actual work time T1 to Tn of the worker, each document data dt1 to dtn, each image data dg1 to dgn, and each audio data ds1 to dsn. These are associated and transmitted from the data transmission unit 13 to the work terminal device 2 through the network N (step S105).

  Accordingly, the work numbers 1 to n, the worker's actual work times T1 to Tn, the document data dt1 to dtn, the image data dg1 to dgn, and the audio data ds1 to dsn are associated with each other. Transferred from the guidance server 1 to the work terminal device 2. For example, document data, image data, and audio data are transmitted in a format that can be viewed by an HTML browser.

  In the work terminal apparatus 2, the control unit 24 stores the work numbers 1 to n, the actual work times T 1 to Tn of the worker, the document data dt 1 to dtn, the image data dg 1 to dgn, and the audio data ds 1 to dsn. Receive and store.

  Next, after initializing the index a to 1 (step S106), the control unit 24 selects the work number 1 having the same value as the index a = 1, and the operator's actual number corresponding to the work number 1 is selected. The operation time T1, document data dt1, image data dg1, and audio data ds1 are selected, and display and reproduction of the document, image, and audio indicated by these data dt1, dg1, and ds1 are started. At this time, the document indicated by the document data dt1 is displayed on the display unit 21 at an appropriate timing within the actual work time T1 of the worker, and the image indicated by the image data dg1 is spent on the worker's actual work time T1. Is displayed on the display unit 21 and the sound indicated by the sound data ds1 is reproduced from a speaker (not shown) (step S107). Accordingly, the time required from the start of display / reproduction of images and sound to the end of display / reproduction is the actual work time T1.

  Here, as described above, if the worker is a beginner and the actual work time is equal to or greater than the standard work time, the time difference is set to 0, so the actual work time becomes equal to the standard work time. . Accordingly, an image (moving image or a plurality of still images) sequentially showing the work contents and a sound for sequentially explaining the work contents are displayed and reproduced while taking a standard work time. For this reason, when a novice worker proceeds with work according to an image or sound, the work can be completed in accordance with the standard work time, and an appropriate work pace can be easily grasped. In addition, the worker can read the document explaining the work content at an appropriate timing to know the work content in detail.

  Further, if the proficiency level of the worker is improved and the actual work time is shorter than the standard work time, the image and the sound are displayed and reproduced while spending the actual work time. The skilled worker can display and reproduce the image and the sound by spending his / her actual work time. Therefore, when the work is performed according to the image and the sound, the worker can perform the work at his / her own work pace.

  When the display / reproduction of the document, image, and sound corresponding to the work number 1 is completed in this way (step S108), the control unit 24 adds 1 to the index a and advances the index a to 2 (step S109). After confirming that the value 2 of the index a does not exceed the last work number n (“No” in step S110), the process returns to step S107.

  Subsequently, the control unit 24 selects the work number 2 having the same value as the index a = 2, and selects the actual work time T2, the document data dt2, the image data dg2, and the audio data ds2 corresponding to the work number 2. The document indicated by the document data dt2 is displayed at an appropriate timing within the actual work time T2, and the image indicated by the image data dg2 is displayed by using the worker's actual work time T2, or the voice data ds2. The indicated voice is reproduced (step S107). When the display or reproduction of the document, image, and sound corresponding to the work number 2 is finished (step S108), the index a is incremented by one (step S109), and the index a exceeds the last work number n. (No in step S110), and the process returns to step S107.

  Similarly, until the index a reaches the last work number n, the actual work time, the document, the image, and the sound corresponding to the work number are read out. Audio display playback is performed. When the document, image, and sound corresponding to the last work number n are displayed and reproduced, and the index a is updated, the index a exceeds the last work number n (“Yes” in step S110). ), The index a is initially set to 1 (step S111), and thereafter, the process returns to step S107 again.

  Accordingly, the operations of the operation numbers 1 to n are repeatedly performed, and the product is repeatedly assembled. Then, when the end of work or rest is instructed to stop the work, the work guidance in steps S107 to S111 is stopped.

  As described above, in the work guidance system according to the present embodiment, since a document, an image, and a sound indicating work contents are displayed and reproduced in addition to the standard work time, a proper work pace can be obtained. I can inform you. In addition, it is possible to make the worker aware of the work pace and to promote the learning of the work.

  In addition, for skilled workers, documents, images, and sounds are displayed and reproduced along with the actual work time of the worker, so that the worker is informed of his / her own working pace, working efficiency and product quality. Can be maintained.

  Next, a method for displaying and reproducing images and sounds in accordance with the standard work time and the actual work time will be described.

  For example, if the image data and audio data are in a format that can be viewed by an HTML browser, the image data dg1 and audio data ds1 corresponding to the work number 1 are displayed and reproduced as shown in the timing chart of FIG. Display reproduction time Tt1, display reproduction time Tt2 for displaying and reproducing image data dg2 and audio data ds2 corresponding to work number 2,..., Display and reproduction of image data dgn and audio data dsn corresponding to work number n Times Ttn are determined, and blank times tt1, tt2, ..., ttn are set between them. In this state, standard work time t1 = (display reproduction time Tt1 + blank time tt1), standard work time t2 = (display reproduction time Tt2 + blank time tt2),..., Standard work time tn = (display reproduction time Ttn + blank time) ttn).

  Therefore, when standard work time is spent for each work of work numbers, image data and audio data may be reproduced or blank time may be inserted according to the timing chart of FIG.

  When an actual work time shorter than the standard work time is spent for each work of the work number, the time difference between the actual work time and the standard work time is subtracted from the blank time. Thereby, the time from the start of display / reproduction of the previous image data and audio data to the start of display / reproduction of the next image data and audio data coincides with the actual work time. For example, the standard work time t1 = (display reproduction time Tt1 + blank time tt1) is set by subtracting the time difference Δt1 from the blank time tt1 and the actual work time T1 = (display reproduction time Tt1 + (blank time tt1−time difference Δt1)). To do.

  In this case, the shortest settable actual work time is a display reproduction time obtained by subtracting a time difference equal to the blank time from the standard work time, and the display reproduction times Tt1, Tt2,... Are continuous as shown in FIG. Become.

  If a blank time is inserted during the display and reproduction of image data and audio data, the time difference may be subtracted from this blank time. Alternatively, when the function of adjusting the display / reproduction speed is given to the browser, the display / reproduction speed of the image data and the audio data may be adjusted, and the time spent for the display / reproduction may be combined with the actual work time. The document data may be displayed at any time within the actual work time.

  Next, a process for measuring the actual work time and recording the time difference will be described with reference to the flowchart shown in FIG.

  Here, the measurement of the actual work time is started simultaneously with the start of display and reproduction of the document, image, and sound corresponding to one work number, and the foot switch 23 of the work terminal device 2 is pressed by the worker at the end of the work. When turned on, the measurement of the actual work time is finished at the time of turning on, and the time from the start of measurement to the end of measurement is acquired as the actual work time.

  First, in the work terminal device 2, when the display / reproduction of the document, image, and sound is started in step S <b> 107 in FIG. 7 (step S <b> 201), the control unit 24 regards the work as being started at the same time. Then, timing of the actual work time is started (step S202).

  The control unit 24 measures whether or not the foot switch 23 has been turned on by the operator while measuring the actual work time (step S203), and the standard work time from the start of the actual work time measurement. Whether or not has elapsed has been monitored (step S205).

  At this time, the foot switch 23 is not turned on (“No” in step S203), and if the standard work time has elapsed from the start of the actual work time measurement (“Yes” in step S204), that is, the actual work time is standard. If it becomes longer than the work time, the control unit 24 interrupts the measurement of the actual work time, resets the actual work time (step S206), and returns to step S201. Therefore, when the actual work time becomes longer than the standard work time, the actual work time is not counted, and the start of counting the actual work time of the next work is awaited.

  Also, if the foot switch 23 is turned on (“Yes” in step S203) from the start of the actual work time until the standard work time elapses (“No” in step S204), that is, the actual work time. If it is shorter than the standard work time, the control unit 24 finishes measuring the actual work time (step S207), and acquires the time from the start of the time measurement to the end of the time measurement as the actual work time.

  Subsequently, the control unit 24 transmits the actual work time, work number, model name of the product to be assembled, and worker ID to the work guidance server 1 through the network N (step S208).

  In the work guidance server 1, the actual work time, work number, model name, and worker ID are received by the data receiving unit 14 and input to the work guidance system control unit 11. When the work guidance system control unit 11 inputs the actual work time, the work number, the model name, and the worker ID, the work guidance system control unit 11 searches the standard work time table 16 in the storage unit 12 for the input model name and work number. The date and time of work execution is recorded in the standard work time table 16 in association with the work number. Then, the work guidance system control unit 11 reads the standard work time corresponding to the input model name and work number from the standard work time table 16, subtracts the input actual work time from the standard work time, and calculates the time difference. Ask. Further, the work guidance system control unit 11 searches the storage unit 12 for the time difference table 17 to which the input worker ID is assigned, and searches the time difference table 17 for the input model name and work number. The previously obtained time difference and work execution date and time are stored in the time difference table 17 in association with the searched work number (steps S209 and S210).

  Such measurement of the actual work time is performed for each work. If the actual work time is shorter than the standard work time, a time difference obtained by subtracting the actual work time from the standard work time is obtained, and this time difference is recorded in the time difference table 17 together with the work execution date and time. Further, when the actual work time is shorter for the same work number with the same model name, a time difference is obtained each time the actual work time is shortened, and the time difference and the date and time of work execution are stored in the time difference table 17. Additional records are made. As a result, time difference history information is formed and recorded in the time difference table 17.

  As the proficiency level of the worker improves, the actual work time becomes shorter and the time difference becomes longer. For this reason, if the history information of the time difference in the time difference table 17 is referred, the proficiency level of the worker can be known.

  Further, since the time difference table 17 is created for each worker, the proficiency level of each worker can be known by referring to the history information of the time difference in the time difference table 17 of each worker.

  For example, in FIG. 1, the management terminal device 3 accesses the work guidance server 1 through the network N, searches the time difference table 17 of each worker from the storage unit 12 of the work guidance server 1, and finds the time difference of each worker. The time difference history information in the table 17 can be obtained and downloaded, and the time difference history information of each worker can be displayed. The administrator or the like can know the proficiency level of each worker by looking at the displayed time difference history information of each worker. Alternatively, if the time difference is maintained as 0 or the situation where the time difference is not updated continues for a long time, it can be inferred that there is some problem to be solved. It is also possible to detect such problems and make design improvements at a development department or the like away from the production site.

  In addition, this invention is not limited to the said embodiment, It can deform | transform variously. For example, documents, images, and sounds are used together, but only images and sounds may be used. In addition, a worker name or the like may be used instead of the worker ID.
