=== Register work start ===
In the electric power company, a field work manager (sometimes referred to as a field agent) who has received an order for work performed at each office 200 is determined. In the electric power company, site workers are determined to perform work in accordance with work sheets delivered from the central communication station 100 or the like. The work slip delivered from the central communication station 100 includes the work slip number, the work content, the work execution date and time, the name of the establishment that issued the work slip, the name of the person in charge who issued the work slip, and the work target. An apparatus (hereinafter referred to as a work target apparatus) and the like are entered. The contents of the work slip (hereinafter referred to as work slip data) are registered in the database 40 in association with the work slip number. Accordingly, the work form data can be referred to as appropriate in the first information processing apparatus 10 and the second information processing apparatus 20.

  The work and various processes performed when the site worker receives the work slip will be described with reference to the flowchart shown in FIG. First, the second information processing apparatus 20 is activated by the field worker who has received the work slip (S2011). When the second information processing apparatus 20 is activated, the site worker then operates the second information processing apparatus 20 to start a predetermined registration work. The registration work here is performed using a function provided by the work management software 21.

  FIG. 3 shows a screen (hereinafter referred to as a work registration screen 300) displayed on the display of the second information processing apparatus 20 when performing the registration work. The site worker inputs the work form number described in the work form in the work form number column 301 provided at the top of the work registration screen 300 (S2012). Then, the work management software 21 automatically inputs the date and time when the work slip number is received in the work slip receipt date and time field 302 of the work registration screen 300 (S2013).

  Subsequently, the work management software 21 searches the database 40 for the corresponding work slip data using the input work slip number as a search key (S2014). If the work management software 21 cannot allocate work slip data corresponding to the search key (S2014: NO), the work management software 21 displays a message on the work registration screen 300 (S2015) and re-assigns the work slip number to the worker. Prompt for input.

  On the other hand, when the work slip data corresponding to the search key can be allocated (S2014: YES), the work management software 21 displays the equipment as illustrated in FIG. 4 on the display of the second information processing apparatus 20. The layout drawing 400 is displayed (S2016). The facility layout diagram 400 shows the layout of the communication facility 211 and the video camera 213 installed in the communication machine room. The facility arrangement information 500 includes a facility installation location 501, a facility ID 502 assigned to each facility, an apparatus name 503, an ID 504 of a video camera 213 capable of photographing the facility, and the like. The facility layout diagram 400 is generated based on the facility layout information 500 illustrated in FIG. 5 registered in the database 40.

  Next, the site worker refers to the equipment layout diagram 400 displayed on the second information processing apparatus 20 and refers to the part of the work target apparatus described in the work slip at hand of the second information processing apparatus 20. The user interface is operated to select from the equipment layout drawing 400 (S2017). When the work target device is selected, the work management software 21 next checks from the database 40 whether or not the selected work target device matches the work target device described in the work slip (S2018). If the work target device is not described in the work slip (S2018: NO), the work management software 21 displays a message to that effect on the display of the second information processing device 20 (S2019).

On the other hand, when the work target device selected by the worker is described in the work slip (S2018: YES), the work management software 21 sends information for identifying the work target device to the first information processing device 10. Is notified to the overall management software 11 operating in the network via the communication network 30 (S2020). Upon receiving the notification, the overall management software 11 identifies the video camera 213 set to shoot the selected work target device from the equipment arrangement information 500 (S2021). Then, the overall management software 11 starts receiving the video transmitted from the identified video camera 213 and displays the video of the work target device on the display of the first information processing device 10 (S2022).

  FIG. 6 shows a state in which an image transmitted from the video camera 213 is displayed. Here, the person in charge of the central communication station 100 operates the user interface, if necessary, to remotely control the shooting direction (pan / tilt), zooming (zoom in / zoom out), etc. of the video camera 213 to perform work in the field. The video camera 213 is set to an optimum state for monitoring. This setting can be automatically performed according to the positional relationship between the video camera 213 and the subject.

The selection of the check field 303 is registered in the database 40 in association with the work slip number. The person in charge of the central communication station 100 can confirm that the check column 303 has been selected by the operator by referring to the contents of the database 40 using the integrated management software 11.

  Next, the field worker performs the work for marking the dangerous zone. Here, the danger zone refers to a part of the apparatus that is not related to the work in the work and causes a failure when the field worker touches the work during the work. In addition, display means that a display serving as a mark indicating that the part is a dangerous zone is attached to the dangerous zone. In this operation, the site worker applies, for example, a colored tape or the like to the danger zone. Here, the entire video of the danger zone marking work is taken by the video camera 213. When the person in charge of the central communication station 100 confirms that all necessary dangerous areas have been displayed using the video from the video camera 213, the person in charge of confirming that the dangerous area has been marked is indicated by telephone, facsimile, etc. To notify the field workers.

  When the work for marking the dangerous zone is completed, the field worker next selects the check box 305 for “Confirmation of dangerous zone marking” on the work registration screen 300 (S2024). When the check column 305 is selected here, the date and time at that time is automatically entered in the “work start date and time” column 306. The date and time when the check field 305 is selected and automatically entered are registered in the database 40 in association with the work slip number. The overall management software 11 can refer to the contents of the database 40. Therefore, the person in charge of the central communication station 100 can confirm that the check column 305 of “dangerous section marking confirmation” is selected by the field worker and the work start date and time.

  When the above operation on the work registration screen 300 is completed, the field worker next performs the work specified in the work slip. Here, as described above, on the display of the first information processing apparatus 10, the video captured by the video camera 213 is displayed in real time. The person in charge of the central communication station 100 can monitor the entire work performed by the field worker in real time.

For example, when it is confirmed afterwards that an abnormality or failure has occurred, the cause of the abnormality or failure can be pursued by using the recorded video.

  When the work instructed in the work slip is completed, the site worker inputs the work end date and time in the “work end date and time” column 307 of the work registration screen 300. When the work end date / time is input, the work management software 21 registers the input work end date / time in the database 40 in association with the corresponding work slip number (S2025). Subsequently, the site worker selects the check column 308 of “Danger zone marking removal” on the work registration screen 300 (S2026). The selection of the check field 308 is registered in the database 40 in association with the work slip number. As a result, the person in charge of the central communication station 100 can confirm that the check column 308 has been selected by the operator.

  Next, the site worker selects the “drawing correction” check field 309 (S2027). In the database 40, drawings showing the state of equipment installed in the communication machine room (hereinafter referred to as equipment management drawings) are registered. When the “drawing correction” check field 309 is selected, the work management software 21 executes a series of processes for correcting the equipment management drawing.

  Here, it is assumed that the work target device is an optical wiring board. When the “drawing correction” check field 309 is selected, the work management software 21 displays a screen (hereinafter referred to as an optical wiring board screen 700) shown in FIG. 7 on which an equipment management drawing for the optical wiring board is described. The information is displayed on the display of the second information processing apparatus 20 (S2028).
