Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 8 by taking as an example a case where maintenance of manufacturing equipment used in a facility 108 (for example, a factory) is performed. First, an outline of the present embodiment will be described with reference to FIGS. 1 to 3 and FIG. 7, and a video of a work transmitted from the television camera 109 and an index sound of the work element are transmitted to the server 102 of the management center 101 and Management Agency Center 1
Detailed processing when storing the information in the fifteen servers 116 will be described later. First, prior to the on-site work, the prospective worker and the manager display and browse a video manual of a device that performs maintenance work on the output device 103 of the server 102 in the center 101. The video manual is a manual that records various work methods such as maintenance or repair for various devices and the past work contents of various devices in the form of a video, and is made into a manual.

In order to display a desired video manual,
By operating the input device 104 of the server 102, the video manual stored in the magnetic disk 106 is searched, and the past work result of the device performing the maintenance work is obtained.
The user selects from the “work log for each device” and the “work video file for each device” to display on the display device 103 for viewing. The “work history list for each device” is data that lists past work histories for each device, and the work history of the device can be known. Also, “Work video file for each device”
Is video data obtained by visualizing the work content for each device, and the work content of the machine description can be visually grasped by video.

If necessary, a video file of the same model of another customer or a similar model is referenced from the "work video file for each model". "Model-specific work video files"
Is video data that visualizes the work content by model.
"Work video file for each device" of the device to be worked on
If there is no, the video data of another same model or a similar model is referred to for reference. Next, the manager determines a work plan based on the information. For example, as the work plan, work contents, workers (accompanied by skilled workers if necessary), work tools and equipment or parts to be carried, work schedule, and required time are determined. After the work plan is determined as described above, the worker determined as described above goes to the facility 108, which is the work site, with the equipment and parts required for the work.

The worker arriving at the facility 108 prepares for starting work. That is, after arriving at the facility 108, the worker connects the television camera 109 and the computer 110 to the server 102 via the Internet 107, and arranges and adjusts a predetermined position with the center 101. After the preparation is completed, the worker declares the start of work from the microphone of the input device 112 of the computer 110. The voice declaring the start of the work is transmitted to the server 102 via the Internet 107, and is output as voice from the output device 103 of the server 102. The television camera 109 is used by attaching it to the worker's head so that the details of the work can be photographed, and transmits the photographed image and the input sound to the server 102 via the Internet 107.

Next, the worker conveys the work procedure from the microphone of the computer 110 by voice. The voice is transmitted to the server 102 via the Internet 107, and is output from the output device 103 of the server 102. At this point, if the work procedure is different from the work plan or one's own idea, the skilled worker on the side of the center 101 can connect the server 102 and the computer 110 via the Internet 107.
In between, the intention is communicated with the workers at the site using video and audio, and the work procedure is instructed.

When the operation procedure is determined as described above, the operator operates the input device 112 of the computer 110 to transmit a manual request signal for requesting the download of the operation manual required for the operation. (Step S201 in FIG. 2). Magnetic disk 10 of server 102
6, a work manual is stored for each predetermined work element, and the manual request signal is a signal for specifying and requesting a part of the manual stored on the magnetic disk 106 necessary for the work. Yes, it is transmitted to the server 102 via the Internet 107.

The server 102 receives the manual request signal and transmits a manual corresponding to the manual request signal among the manuals stored on the magnetic disk 106 (step S301 in FIG. 3). The computer 110 receives the manual and displays it on the display device of the output device 111 (step S202).
Thereby, the worker can refer to the manual required for the work using the computer 110.

During the operation, the worker can
A video request signal for requesting download of the video data stored in the server 102 of the center 101 is transmitted (step S203). Magnetic disk 1 of server 102
06, the video data is stored by being divided for each predetermined work element.
6 is a signal for specifying and requesting a specific portion (predetermined portion necessary for work) of the video data stored in the server 6 and transmitted to the server 102 via the Internet 107.

The server 102 receives the video request signal and transmits a video corresponding to the video request signal in the video data stored on the magnetic disk 106 (step S302). The computer 110 receives the video and displays it on the display device of the output device 111 (step S204). Thus, the worker can refer to the video necessary for the work using the computer 110. In addition, when a question occurs during the operation, the operator presses a predetermined button of the input device 112 to transmit an instruction request signal (step S205). The instruction request signal is a signal for asking the skilled worker of the center 101 for an instruction of a work, and is transmitted to the server 102 via the Internet 107.

The server 102 receives the instruction request signal, blinks the display device of the output device 103 in red (step S303), and notifies that the worker at the site is waiting for an instruction. As a result, the skilled worker on the center 101 side knows that the work site is waiting for an instruction, and immediately responds. That is, the skilled worker of the center 101 communicates with the worker at the site via the Internet 107 and the computer 110 by using the video and the sound from the input device 104 of the server 102, and transmits instructions to the worker.

When an unexpected situation occurs due to a trouble or an operation error, the operator promptly presses the predetermined button to transmit an instruction request signal in the same manner as described above, and obtains an instruction from the center 101. . In the case of an emergency, a serious accident, or the like, the skilled worker on the center 101 side receives an instruction on a response means from a person in charge of the upper seat. If necessary, the video data in the server 102 of the center 101 is reproduced, and the work is retroactively reviewed. As described above, the worker deals with the preparations before the start of the work and the abnormalities that occur during the work.

Next, the processing when the worker performs the work will be schematically described. Before starting the work of each work element, the worker declares the name of the work element to be started with “XX work start” by voice. Here, the work such as maintenance and repair is constituted by a series of work such as a cover opening work of a work target device and a circuit board replacement work, and a work of a predetermined unit is defined in advance as a work element. The name of the work element declared in the audio is an index audio used later for indexing the video, and the name of the work element to be declared is unified in advance so that the index can be easily created. Have been. At the end of each work element, the worker declares by voice “XX work end” and declares that the work with the work element name XX has been completed. Thereafter, the above processing is repeated. When all the necessary work elements have been completed, the worker declares that the work has been completed by declaring "XX work completed" at the end of the last work element and declaring "work done today". I do.

Thus, from the television camera 109,
Video data and audio data as shown in FIG. 7 are transmitted to the server 102 via the Internet 107. That is, when a work is composed of n work elements, first, voice data indicating that the work is started is transmitted.
Next, audio data to start the first work element (work element 1), video data of the first work element, and audio data to end the first work element are transmitted. Similarly, audio data for starting the nth work element (work element n), video data of the nth work element, n
The audio data to end the second work element is sent,
Finally, a work end declaration indicating that all the work elements have been completed is transmitted as audio data.

Each of the work elements 1 to n has a specific name in advance, and the worker declares the work element name. Each audio data is data from which the server 102 creates an index, that is, index audio. Finally, the worker terminates the connection between the server 102 and the television camera 109 and the computer 110,
All manuals and the like downloaded to the computer 110 are deleted (step S206). Thereby, it is possible to prevent the leakage of the confidential data due to the computer 111 or the like being left behind at the work site or being stolen.

Next, the processing for storing the video and audio of the work element transmitted from the television camera 109 in the server 102 in the work process will be described in detail with reference to FIG. First, when the server 102 receives the work start declaration from the worker at the work site (step S401 in FIG. 4), the operator of the center 101
By operating the input device 104, a main index including a model name, a customer name, a work location, a work content, a work date and time, and a worker name is input and stored in the magnetic disk 106 (step S402).

Next, the server 102 communicates with the Internet 10
As shown in FIG. 7, the video camera 109 receives a video of the work and an index audio signal representing the work element from the television camera 109, and creates an index from the index audio signal (step S403). For example, regarding the work element 1, an index of the work element 1 is created from the audio index “work element 1”, and based on the audio indexes “work element 1 start” and “work element 1 end”, the video of the work element 1 is displayed. An index is created to indicate the location of. It is also possible to create an index indicating the location of the video of the work element 1 from only the index sound at the start of each work element. In this case, the audio index at the end of each work element is unnecessary.

When the index is created as described above, the server 102 performs processing to apply the index to the preset work element by voice recognition using the index worker's index voice. If the voice cannot be recognized, display data indicating that the voice cannot be recognized is transmitted from the server 102 to the computer 110, and the output device 1
The display device of No. 11 indicates that the recognition is not possible, and the operator repeats the display, or the skilled worker of the center 101 judges and inputs the index of the work element to the server 102 directly from the input device 104. The notification that the recognition is not possible may be performed by transmitting voice data indicating that the recognition is not possible from the server 102 to the computer 110 and outputting the voice data from the speaker of the output device 111 of the computer 110 by voice.

Next, as shown in FIG. 8, in the received work video, the work element video corresponding to the created index is associated with the index, and the work element video and the video Is stored in the magnetic disk 106 (step S404). In this way, the server 102 of the center 101
The images of the work elements sent from 8 are sequentially stored with the corresponding indexes. Thereafter, the above process is repeated until the work end declaration is received (step S4).
03 to S405). When the work end declaration is received (step S405), a work end index indicating the end of all the series of work is stored on the magnetic disk 106 (step S406). After that, the indexed video file created as described above is
7 to the server 116 (step S40).
7), end the processing.

By performing the above processing, a file containing video data of a plurality of work elements is stored in the magnetic disk 106.
The file is indexed as shown in FIG. That is, a main index including a model name, a customer name, a work location, a work content, a work date and time, and a worker name, and an index of each work element created based on the index voice (in FIG. And a correspondence table indicating the storage location of each work element video data in the file is created. in this way,
By creating an index from the audio for the index, making the index correspond to the video for each work element, creating indexed video data, and storing the indexed video data in the server 102, if the search is performed using the index, the required video is obtained. Can be easily displayed on the display device of the server 102.

The file of the indexed video data created as described above is stored on the magnetic disk 106 and transmitted from the server 102 to the Internet 107.
Is transmitted to the server 116 via the
Is also stored. At this time, a specific part (for example, data that is considered to be infrequently used) of the file stored on the magnetic disk 106 is deleted, and a specific necessary part (for example, a part that is considered to be frequently used) is deleted. ) Is stored on the magnetic disk 106. By doing so, frequently used manuals or video data, or only the latest manuals or video data are stored in the server 102, and rarely used manuals or video data or old manuals or video data are stored in the server 116. , The storage capacity of the magnetic disk 106 of the server 102 can be reduced.

After the completion of the work, if a trouble occurs in the equipment on which the work was performed, the skilled worker and the responsible person of the center 101 refer to the video data of the work to determine whether the work was appropriate. While reviewing, the manual will be revised and knowledge will be shared among skilled workers as described later. In addition, the trouble reporter incorporates the edited video data into the written report,
It becomes possible to report the content of the trouble, the coping method, and the like more easily. The manual is revised according to the change of the work procedure and the work content, and the manual is added according to the new model by changing and adding the programs and data stored in the magnetic disk 106 of the server 102 on the center 101 side as needed. .

At this time, the first creation date and the revision date are displayed as a history attached to the end of the text of the manual, and the history is linked with the video data, so that the history can be displayed as necessary. By clicking, a video or the like of the revised content may be viewed. This makes it possible to know the history of revisions to the latest manual and to gain a deeper understanding of the current work. In addition, the teaching material may be created using the accumulation of video data with an index, such as a difference in a work procedure for each model or a difference in work content for each model of the same work element. In the above embodiment, the server 102 creates the indexed video data, but the server 116 may create the indexed video data. In this case, the TV camera 1
09 through the Internet 107 to the server 10
2 and the server 116, the video data and the index audio signal are transmitted, and the server 116 performs the same processing as in FIG. 4 to create the indexed video data.

In this case, the television camera 109 at the work site
Transmitting a video of a plurality of work elements on which a worker works, and an index sound representing each of the work elements to a server 116 via the Internet 107. Receiving the index and the index audio, creating an index from the index audio, creating and storing indexed video data in which the work element video is associated with the work element index (steps S401 to S406). And the server 102 to the server 11
Requesting the specific indexed video data from the management server 116, and transmitting the indexed video data corresponding to the request from the management server 116 from the indexed video data stored in the management proxy server 116 to the Internet. What is necessary is just to comprise the step of transmitting to the server 102 via the server 107 and the step of storing the indexed video data received from the server 116 in the server 102.

Next, the processing when the work manual is revised will be described with reference to FIGS. In addition, work manuals that explain work procedures include not only text-based work manuals that have been used in the past, but also work manuals with explanatory diagrams added to texts and work manuals with video added to texts. Cases are also assumed. When revising an existing manual (old version manual) stored in the magnetic disk 106 of the server 102, the revision is performed using the server 116 of the management agency center 115. In this case, as shown in FIG.
Sends a manual revision request signal for requesting a revision of the manual to the server 1 via the Internet 107.
16 (step S501). The manual revision request signal is a signal for designating the manual to be revised and the content to be revised and requesting the revision. The management agent uses the server 116 or another computer (not shown) in response to the manual revision request signal, and designates the designated manual among the existing manuals stored on the magnetic disk 120. The content is revised (step S601), and the revised manual is stored on the magnetic disk 120 of the server 116.
The revised manual is transmitted to the server 102 via the Internet 107 (step S602).
Since the manual before revision may be used later, it is stored on the magnetic disk 120 without erasing.

The server 102 receives the revised manual (step S502), deletes the manual before revision, replaces it with the revised manual, and stores it on the magnetic disk 106 (step S503). As a result, only necessary data such as the latest manual and indexed video data are stored in the server 102, and old manual and indexed video data and the like that are not frequently used are stored in the server 116.
That is, the specific data such as the latest version of the manual having high usage is stored in the server 102, and the specific data such as the old manual having low usage is stored in the server 11.
6, the magnetic disk capacity of the server 102 can be reduced, and the operator can refer to the manual and the video efficiently by accessing the server 102. When it is necessary to refer to an old manual or the like, an old manual or the like stored in the server 116 may be referred to.

The manual stored in the server 102 is
As described above, the server 102 receives the manual request signal from the worker and transmits a manual corresponding to the manual request signal among the manuals stored on the magnetic disk 106 (step S3 in FIG. 3).
01). The computer 110 receives the manual and displays it on the display device of the output device 111 (step S202). Thereby, the worker can use the computer 11
Using 0, the user can refer to the manual required for the work.

As described above, the work data management method according to the present embodiment uses the work data used when referring to the work method in order to perform the work at the work site where the equipment to be worked is provided. In the work data management method for managing the work data, a specific work manual from the work manuals stored in the management agent server 116 provided at the center of the agency that manages the work data is transmitted to the communication path 1.
