[3. Operation of equipment inspection support system]
Next, operations that can be performed by the information terminal 5 after logging in to the equipment inspection support system 1 using the information terminal 5 will be described with reference to FIGS. 10 and 11. FIG. 10 shows an operation flow of the initial screen display routine. From the screen shown in FIG. 9 displayed after login, the worker selects the contents shown in (1) to (4) in the figure (S101b). The selected information is received (S101a), and the server 2 determines what is selected (S102a). When “work content acquisition” in (1) is selected (S103a), “work content acquisition routine” is activated (S103a), and “defect case search” in (2) is selected. In this case (S104a), the “defect case search routine” is activated (S105a), and when “view instruction manual” in (3) is selected (S106a), the “instruction manual reference routine” is selected. When “Manual Reference” is selected (S108a), the “Manual Reference Routine” is started (S109a).

  Next, the “work content acquisition routine” started from the initial screen display as described above will be described with reference to FIG. In the “work content acquisition routine”, as shown in the screen of FIG. 9, one of “equipment ID”, “worker ID”, “work place”, “work ID”, or “position information” needs to be selected. In this embodiment, a case where “work ID” is designated will be described. The process is the same when other options are selected. The device inspection support server 2 sends a transmission request of “work ID” to the information terminal 5 (S111a).

  The information terminal 5 that has received the transmission request for “work ID” (S111b) displays an input screen for “work ID” (S111b). When the worker inputs “work ID”, the information terminal 5 transmits the input content to the server 2 (S112b). The transmission / reception unit 12 and the transmission / reception processing unit 131 in the server 2 receive the information (S112a), determine the input content, and the central processing unit 13 activates the work content collection unit 134. The work content collection means 134 searches the work content DB 154 for work content that matches the work ID. If there is a matching work content, the work content collected by the work content sending means 135 is sent to the information terminal 5 (S113a).

  In FIG. 11, the operation when the input “work ID” is incorrect is not defined, but processing such as displaying an error screen and prompting the input of “work ID” again is performed. The information terminal 5 that has received the work content displays the received content on the screen (S113b). Next, the worker determines whether to continue to view the contents next, and when the worker selects to continue (S114b), a screen display request for the corresponding page is transmitted to the server 2 (S115b). Upon receiving the next page display request (S114a), the server 2 retrieves and acquires the work content of the designated page by the work content collection unit 134, and the work content transmission unit 135 transmits the obtained information. The destination transmitted by the work content transmitting unit 135 may be selected from a predetermined destination other than the information terminal 5 and transmitted. The above operation is repeated until the worker finishes displaying the work content.

  If the worker does not want to continue the work content, the information terminal 5 notifies the server 2 of the end of the display of the work content (S117b). The work content modification means 144 in the server 2 that has received the display end request (S116a) automatically updates the work content performed by the worker (S117a). Alternatively, a screen asking whether to update the work content is displayed on the information terminal 5, and the update is performed when the operator of the information terminal 5 permits it.

  Further, a series of operations have been started after selecting the “work ID” in the above description. However, when communication is performed including the device specific information 541 at the time of login or the like, the device specific information 541 is included. Since the work ID at that time is immediately determined from (the daily work schedule, the work ID, and the table of the information terminal), the work content is automatically collected and notified to the information terminal. it can. Similarly, the position information acquisition unit 533 of the information terminal 5 acquires the position information, and notifies the server 2 of the position information acquired by the position information transmission unit 534. The work content can be specified from the information DB 153 according to the installation location of the device and the received position, and the work content can be transmitted to the information terminal 5.

[4. Assist from other devices]
Next, while the information terminal 5 and the server 2 are communicating with each other, another terminal joins the session and notifies the information terminal 5 of voice information, text information, and image information with reference to FIG. explain. This function is used when, for example, a veteran person in charge of the target device who operates another terminal gives advice to a worker on the actual site. Information from the information terminal 5 is processed by the work content display means 139 to be displayed on the screen of another terminal.

  An operator operating another terminal can talk to the microphone, write text on the screen like a chat, or attach a camera to a PC (Personal Computer) to distribute images. (S121c), the second information receiving means 138 in the server 2 receives the information (S121b), and the first information transmitting means processes the received voice information, character information, and image information. Alternatively, the information is transmitted to the information terminal 5 without being processed.

  The information terminal 5 may reproduce the received voice information, display characters on the screen, or display images using the built-in functions of the information terminal 5 for the received voice information, character information, and image information. it can. As a result, the worker can receive an appropriate assist when there is a task that is difficult to understand only by the work content. Whether to process or not is stored in the storage unit 14 as system data.

  Next, during the work, an “assist” button that is a request designating section shown in FIG. 13 is displayed, and when the operator presses the button, a destination registered in advance in the target device automatically is displayed. The function of automatically calling and inviting the operator to a session communicating with the server 2 will be described with reference to FIG. In FIG. 13, the content of page #n of the work content and a screen 13 </ b> A having an “assist” button as a request designating part are displayed in a screen display frame 81 of the information terminal 5. When the worker presses the “Assist” button displayed on the screen of the information terminal 5, the information terminal 5 notifies the server 2 that the “Assist” button has been pressed (S141a).

  The server 2 that has received the “assist” button pressing information (S141b) recognizes that the “assist” button has been pressed, activates the second information transmitting means 141, and is registered in the target device, for example, the target device. A destination such as a veteran person in charge is called (S142b). The other terminal that receives the call (S141c) makes a request for participation in the session between the information terminal 5 and the server 2 to the server 2 when the operator permits (S142c). The automatic connection means 143 in the server 2 that has received the request for participation in the session joins the session, notifies the other terminal that it has successfully joined the session (S144b), and informs the information terminal 5 The assistant notifies that the assistant has joined the session (S145b), and the information terminal 5 displays a screen display indicating that the assistant has joined the session based on the notification (S143a). Next, other terminals participating in the session communicate with the information terminal 5 (S144c, S144a).

  When the browsing of the work content, the content change, etc. are completed, the log recording / editing unit 142 of the server 2 stores the work performed by the worker in its own storage unit 14 as a log. Further, the log recording / editing unit 142 refers to the recorded log, and automatically updates the work content from the work content recorded in the log or creates a new work content. This operation may be configured such that an operator designates a point of work from a log during work in advance and newly registers a point of work content at the end of the work. The log storage can be performed by outputting the log to an external log storage server.

[5. When trouble occurs]
When the worker encounters a malfunction of the device during work, the malfunction information generated using the information terminal 5 can be registered in the malfunction case. FIG. 15 shows a screen displaying the work content (work point) 15E on the information terminal 5. The work content display screen 15A includes each work content, a failure case reference button 15B, a failure case registration button 15C, and a “working point of view” 15D in the work. When the failure case registration button 15C is pressed, failure case registration button pressing information is transmitted to the server 2 (S161a), and the server 2 that has received the pressing information (S161b) transmits a failure content registration screen to the information terminal 5 (S162b). ).
