  Next, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram showing the configuration of the maintenance apparatus according to the first embodiment of the present invention. The maintenance device 20 is connected to an external device such as a maintenance target device that is a maintenance target and an approval device that approves whether or not a maintenance instruction can be executed by a communication unit.

  The maintenance device 20 is realized by a portable information device such as a portable personal computer or PDA (personal digital assistant) or a stationary information device such as a desktop personal computer. Further, the maintenance device 20 may be an information device designed exclusively.

  When the maintenance device 20 is realized by a portable information device, a maintenance worker can carry the maintenance device 20 and carry out maintenance work. When the maintenance device 20 is realized by a stationary information device, the maintenance device 20 is installed near a maintenance target device, and a maintenance worker can perform maintenance work without carrying the maintenance device 20.

  The maintenance device 20 includes a communication device 21, an input device 22, a display device 23, a CPU 24, and a storage device A25.

The working unit A27 includes a history area A for storing maintenance instruction execution history data, a procedure manual area A for storing work procedure manual data in which a procedure for performing maintenance work is described using a maintenance instruction, A maintenance screen area A for holding display data of a maintenance screen for inputting a maintenance command and displaying an execution result is included. The processing unit A26 includes a program A that executes the function of the processing unit A26, and an approval command area that stores a maintenance command that requires approval.

  Next, the operation of the maintenance device 20 will be described. The configuration and operation of the maintenance device 20 are the same as those of the maintenance device 20 of the second embodiment to be described later, and the detailed description will be described in the description of the second embodiment. Below, operation | movement of the maintenance apparatus 20 is demonstrated.

  First, the maintenance device 20 inputs a maintenance command and displays a maintenance screen for displaying an execution result on the display device 23. When the maintenance device 20 detects that a maintenance command has been input to the maintenance screen, the maintenance device 20 collates the maintenance command included in the work procedure manual data and the execution history data in accordance with the procedure, and then inputs the maintenance to be input next. Guess the instructions for. Subsequently, the maintenance device 20 compares the input maintenance command with the estimated maintenance command, changes the display data to highlight the mismatched portion on the maintenance screen, and displays it on the display device 23. To do.

  Next, the maintenance device 20 checks whether the inputted maintenance instruction is registered in the approval instruction area. When the input maintenance command is registered in the approval command area, the maintenance device 20 uses the input maintenance command, maintenance screen display data, execution history data, and work procedure manual data as an approval request. Attach it to the approval device installed outside and send it through the communication means. When the inputted maintenance instruction is not registered in the approval instruction area, the maintenance device 20 executes the inputted maintenance instruction and adds information on the executed maintenance instruction to the execution history data. .

  The storage device B35 is provided with a corresponding working unit B37 corresponding to the case where a plurality of maintenance workers perform maintenance work at each customer site, and one approver time-sharing approval of a plurality of maintenance workers. And can be executed in parallel. The work procedure manual data and the execution history data are the same as the work procedure manual data and the execution history data held in the maintenance device 20, respectively.

  Next, the operation of the embodiment of the present invention will be described with reference to the drawings. First, the maintenance organization to which the maintenance worker belongs installs program A and approval command information in advance in the processing unit A26 of the maintenance device 20, and installs program B in advance in the processing unit B36 of the approval device 30.

  Next, when maintenance work is required, the maintenance organization investigates the operating environment and the failure state of the maintenance target device 10, decides what kind of maintenance work is executed at what time, and maintenance that can execute the maintenance work. The operator is determined and work procedure manual data as shown in FIG. 5 is created. Note that the work for investigating the operating environment and the failure state can also be a maintenance work.

  The maintenance organization registers the created work procedure manual data in the work unit A27 of the maintenance apparatus 20, and notifies the maintenance worker of a maintenance work execution command. When the maintenance apparatus 20 is a stationary type, the maintenance organization can also register work procedure manual data in the maintenance apparatus 20 from a remote location via the WAN 42 and the LAN 41. In addition, the maintenance organization can record the work procedure manual data in a storage medium and carry it with the maintenance worker, and the maintenance worker can register with the maintenance device 20 at the site.

  The maintenance worker performs maintenance work on the site with reference to the work procedure manual. Hereinafter, the operation when the maintenance work described in the work procedure manual of FIG. 5 is executed will be described. In this case, since part replacement work is included, the maintenance worker carries the replacement part (magnetic disk device) specified in the work procedure manual or delivers it to the site in advance. In the following description, it is assumed that the maintenance device 20 is a portable information device and is carried by a maintenance worker when going out for maintenance work.

  Next, the operation of the maintenance work by the maintenance worker will be described with reference to the sequence diagram of FIG. First, the maintenance worker turns on the power of the maintenance device 20 to start up, and starts the program A of the processing unit A26. When the processing unit A26 is activated, it displays a maintenance screen, automatically connects to the approval device 30, and is displayed on the display device 23 when the maintenance command can be approved in conjunction with the processing unit B36. Displays the message “Instruction can be executed” on the maintenance screen. In this state, the processing unit A26 waits for an execution key to be input on the maintenance screen (S51 / No).

  The maintenance screen is controlled by the processing unit A26, and is used as a screen for a maintenance worker to input a maintenance command from the input device 22 and execute maintenance. The maintenance screen display data is a maintenance screen area A of the working unit A27. Retained. The processing unit A26 displays the execution result of the maintenance instruction on the maintenance screen or displays information necessary for the maintenance.

  FIG. 10 is a diagram showing an example of contents displayed on the maintenance device 20. FIG. 10 shows a state in which the contents of the maintenance screen and work procedure manual data are displayed at the same time. The maintenance screen in FIG. 10 shows a state after the maintenance worker inputs the command Z (01.23.45.67). Hereinafter, the contents of FIGS. 3 to 8, 10, and 11 will be described as specific examples. However, the contents of the maintenance screen and execution history data change as the operation progresses.

  In order to execute the procedure (3) according to the work procedure manual, the maintenance worker first inputs a command Z (z11), which is a maintenance command for connecting the maintenance device 20 to the maintenance target device 10, and operates the execution key. . The maintenance worker understands that z11 is the IP address “01.23.45.76” of the connection destination from the definition of the command Z and the work procedure manual data, but erroneously “command Z (01.23. 45.67) ”will be described as a specific example.

  When the processing unit A26 detects that the execution key has been operated on the maintenance screen (S51 / Yes), the processing unit A26 estimates a maintenance command to be input next based on the work procedure manual data and the execution history data (S52). Subsequently, the processing unit A26 compares the input maintenance instruction with the estimated maintenance instruction, and checks whether there is a mismatch, that is, an error (S52). When an error is detected (S53 / Yes), the processing unit A26 changes the display data of the maintenance screen so as to highlight the mismatched portion displayed on the maintenance screen (S54). If there is no error (S53 / No), the processing unit A26 proceeds to the next step S55 without changing the maintenance screen display.

  The example of the execution history data shown in FIG. 6 shows a state in which up to the instruction W (w11) has been executed. However, in the case of a specific example, the maintenance instruction has not been executed at this time, so FIG. Instruction Z (z11) to instruction W (w11) do not exist in the execution history data. Since there is no maintenance instruction in the execution history data, the processing unit A26 searches in order from the work procedure (1) of the work procedure manual data, searches for the first maintenance command, and detects “command Z (z11)”. To do. Further, the processing unit A26 detects that the value of z11 is “01.23.45.76” from the description of the IP address of the maintenance target device 10 in the work procedure manual data. From the above, the processing unit A26 can infer that the maintenance instruction to be executed next is "instruction Z (01.23.45.76)".

  On the other hand, since the inputted maintenance instruction is “instruction Z (01.23.45.67)”, the processing unit A26 compares the argument value “01.23.45.67” as a result of comparison. And the display data is changed so that the display of the portion is highlighted. Thereby, the display data of the maintenance screen held in the maintenance screen area A is changed, and the display of the maintenance screen displayed on the display device 23 is also changed.

  As a highlighting method, there is a method of changing the display color of the character of the corresponding part to a different color (for example, red) from other parts, making the character bold, adding an underline, or combining these. . However, the emphasis method may be other than these, as long as the maintenance worker or the approver easily recognizes an error.

  In the above description, the case where the argument can be estimated is taken as an example, but the contents of the argument cannot always be estimated. When the argument cannot be estimated, the processing unit A26 can estimate only the instruction part excluding the argument (for example, the instruction Y part of the instruction Y (y11)) and compare only the instruction part. In this case, the processing unit A26 highlights only the instruction part (for example, the part of the instruction Y).

  Next, the processing unit A26 checks whether the inputted maintenance command is registered in the approval command area of the processing unit A26 (S55). Next, when the input maintenance command is not registered in the approval command area of the processing unit A26 and no approval is required (S56 / No), the processing unit A26 executes and executes the input maintenance command. Execution history data is generated by adding time information to the command information, and is recorded in the history area A of the working unit A27 (S62).

  When the inputted maintenance command is registered in the approval command area of the processing unit A26 and approval is required (S56 / Yes), the processing unit A26 proceeds to step S57. In the specific example, since the instruction Z (z11) is registered in the approval instruction area, the processing unit A26 determines that approval is necessary, and proceeds to step S57.

  Next, the processing unit A26 receives maintenance screen display data held in the maintenance screen area A, execution history data held in the history area A, and work procedure manual data held in the procedure manual area A. The information on the maintenance command is attached to the approval request and transmitted to the approval device 30 (S57). In the case of a specific example, the processing unit A26 displays the maintenance screen display data changed to highlighted, the execution history data and work procedure manual data held in the work unit A27, and the “command Z (01.23.45.67). "Is attached to the approval request and transmitted to the approval device 30 (S57).

  Next, when receiving the approval request, the approval device 30 notifies the processing unit B36 that the approval request has been received. The processing unit B36 extracts a work procedure manual number from the received work procedure manual data, and confirms whether or not there is a work unit B37 that includes the extracted work procedure manual number in the ID area. Further, the processing unit B36 generates a new work unit B37 if the corresponding work unit B37 does not exist, and registers the received work procedure manual number in the ID area.

  Subsequently, the processing unit B36 stores the received maintenance screen display data, execution history data, and work procedure manual data in the maintenance screen region B, history region B, and procedure manual region B of the work unit B37, respectively. Further, as shown in FIG. 11, the processing unit B36 generates approval screen data in which the received maintenance screen display data, execution history data, work procedure manual data, and input maintenance instructions are combined into one screen, The information is displayed on the display device 33 (S58). Note that the approval screen data may not display all of the received maintenance screen display data, execution history data, work procedure manual data, and inputted maintenance commands at the same time. For example, what the approver displays may be selected.

  When the approver performs a plurality of approval tasks in parallel, the processing unit B36 can control the approver so as not to interfere with the tasks of the approver. For example, the processing unit B36 can display a message on a part of the display device 33 to notify the approver that the approval screen is ready to be displayed, and can display the approval screen created according to the instruction of the approver. . In this case, the processing unit B36 displays the customer name and the maintenance worker name on the approval screen as shown in FIG. 11 so that the maintenance work can be easily recognized on the approval screen. Also good.

  FIG. 11 shows an example of the approval screen. The content of the maintenance screen in FIG. 11 shows a state of a specific example at this time, and displays that the instruction Z (01.23.45.67) is input in the bottom line. Further, “01.23.45.67” of the erroneously input argument portion is highlighted in bold and underline.

  By viewing the maintenance screen on the approval screen and the display of maintenance commands to be approved, the approver can share the information with the maintenance workers at the site and recognize the extent to which the maintenance work has progressed. it can. Furthermore, the approver can avoid overlooking the wrong part by highlighting. Further, the approver can check what maintenance commands are executed in which order on the execution history data display screen. The approver can easily confirm whether the work procedure is correctly performed by comparing the displayed work procedure manual data with the execution history data.

  The approver confirms the display content of the approval screen and determines whether or not the maintenance instruction entered on site can be executed. If the approval is approved, the approval button is operated on the approval screen. Operate the denial button on the approval screen. When detecting the operation of the denial button, the processing unit B36 returns a denial response to the maintenance device 20 (S59 / Yes). Further, when detecting the operation of the approval button, the processing unit B36 returns an approval response to the maintenance device 20 (S60 / Yes).

  Next, when the maintenance device 20 receives a denial response, the processing unit A26 discards the input maintenance command without executing it, creates a message that the execution of the input command is denied, and creates a maintenance screen. (S61). For example, in the case of FIG. 10, the processing unit A26 displays a message “The execution of the instruction has been denied by the approver” on the line next to the line displaying “> Command Z (01.23.445.67)”. Is displayed. If denied, the processing unit A26 does not add execution history data.

  When the maintenance worker confirms the rejection message, the cause of the error is investigated. In the case of a specific example, the maintenance operator can easily recognize that the cause of the error is an erroneous input of the IP address of the maintenance target apparatus 10 by highlighting the maintenance screen. If it is difficult to identify the cause, the maintenance worker can inquire the approver to identify the cause. Inquiries to the approver may be made verbally by telephone, or if the maintenance device 20 is equipped with an e-mail function via a wireless telephone network, it can also be inquired by e-mail.

  Further, if the approver is configured to be able to input a comment on the approval screen, the processing unit B36 can return a comment in which a reason for rejection or a method of correcting an error is input in the case of a rejection, with a rejection response. The maintenance device 20 displays the returned comment on the display device 23. The maintenance worker can also know how to correct the error from the displayed comment.

  When the correction method is known, the maintenance worker can input the correct maintenance instruction again and proceed with the maintenance operation correctly. When the maintenance worker inputs a correct maintenance instruction, the processing unit A26 operates in the same manner again from step S51. The maintenance device 20 can expect that an approval response will be returned from the approval device 30 because it has been correctly input this time.

  When the maintenance device 20 receives the approval response, the processing unit A26 executes the input instruction Z (z11) as described above, and the processing unit A26 adds time information to the executed instruction information and executes registration. History data is generated and recorded in the history area A of the working unit A27 (S62).

  In the case of a specific example, the processing unit A26 creates registration execution history data “2007.05.10 10:25:00 instruction Z (01.23.45.76)”, and records the history area A of the working unit A27. Add to. The processing unit A26 executes the instruction Z (z11) and connects the maintenance device 20 to the maintenance target device 10.

  Next, an operation following the operation of the instruction Z (z11) in the specific example will be described. Since the instruction Y (y11) input by the maintenance worker is not registered in the approval instruction area, the input maintenance instruction is executed without approval, and the instruction Y (y11) is added to the execution history data. The Since the instruction Y (y11) is an instruction for displaying the failure history of the maintenance target instruction, the processing unit A26 sends a failure history information transfer request to the maintenance target apparatus 10, and when the failure history information is returned, the failure history information Is displayed on the display device 23.

  Since the next command W (w11) does not require approval, the command W (w11) is executed without approval and the execution history data has the contents shown in FIG. Thereafter, the maintenance worker executes the procedures (6) to (7) and inputs the instruction V (v11) when executing the procedure (8). The processing unit A26 sequentially refers to the work procedure manual data from the procedure (1), and finds the instructions Z (z11) to W (w11) in the procedures (3) to (5). Subsequently, the processing unit A26 sequentially refers to the procedure (6) and the subsequent steps, thereby estimating that the maintenance command to be executed next is the command V (v11) of the procedure (8). As described above, the present invention is created by expressing the work procedure manual with the maintenance instruction, so that the maintenance instruction to be executed next is estimated by comparing the execution history data and the work procedure manual data in the execution order. it can.

  If the input instruction is not the instruction V (v11) but the instruction X (x11), the processing unit A26 changes the display data of the maintenance screen so as to highlight the input “instruction X” portion. .

  Next, since the command V (v11) needs to be approved (S56 / Yes), the processing unit A26 requests the approval of the maintenance screen display data and the execution history data together with the work procedure manual data (S57). . The approval device 30 displays the maintenance screen, execution history data, and work procedure manual data on the display device 33 (S58), but the contents of the maintenance screen and the execution history data are different from those of the instruction Z (z11).

  The approver can confirm that the maintenance work has proceeded with reference to the execution history data and the maintenance screen, and the instruction Y (y11) and the instruction W (w11) executed before the instruction V (v11) are obtained. You can check whether it was executed correctly. The approver can make a determination including not only the command V (v11) but also the previous process, and can make an approval response or a denial response.

  In this way, the present invention displays execution history data before an instruction that needs to be approved even if the approval of an intermediate instruction is omitted, so that the approver can check whether the maintenance work has been performed in the correct procedure. it can. Therefore, even if there is an input work error in the middle of an instruction that does not require approval, the same effect as preventing the work error can be obtained if the recovery procedure for the command with the input work error is successful.

  The command to be registered in the approval command area may be determined according to the operating environment of the maintenance system to be applied. For example, it is possible to eliminate the need for approval for an instruction that does not cause any harm or can be easily recovered within a working time even if it is mistakenly executed. For example, there is no actual harm even if the instruction Y (y11) for reading out the failure history is erroneously executed in the procedure of executing the instruction W (w11). The maintenance worker can advance the correct work procedure if he / she notices a work mistake by highlighting and re-inputs the correct command W (w11).

  On the other hand, commands that cause actual harm or are not easy to recover if executed incorrectly should be registered in the approval command area. For example, if the maintenance worker mistakes the connection destination by inputting the command Z (z11), the maintenance device 20 performs unauthorized access to a device that is not the maintenance target by executing the subsequent command. For this reason, the instruction Z (z11) is particularly effective when it is registered in the approval instruction area for argument confirmation.

  As described above, the present invention displays the history and work procedure manual related to the command input by the maintenance worker on the remote approval device at the stage of executing the maintenance work, and executes after waiting for the approval person's response. To do. Accordingly, the present invention can prevent a work mistake that a maintenance worker erroneously executes a maintenance command.

  Furthermore, since the present invention can limit the commands that require approval, the maintenance work time can be shortened. Thereby, the maintenance worker can perform the maintenance work more safely and efficiently. Further, the present invention compares the work procedure manual data and the work history data to infer the next instruction to be executed, and detects and highlights the erroneous input portion by comparing the input and the estimation result. It is possible to support the approval work more reliably and efficiently.

  In addition, the present invention may be configured such that the operations of steps S52 to S54 in FIG. 9 are performed between steps S56 and S57 (referred to as operation mode A). In the operation mode A, the processing unit A26 executes steps S55 and S56 before executing steps S52 to S54. Accordingly, the processing unit A26 executes steps S52 to S54 only when the inputted maintenance instruction is an instruction that requires approval. That is, in the operation mode A, when the inputted maintenance instruction is an instruction that does not require approval, the processing time of the maintenance device 20 is shortened by omitting the execution of steps S52 to S54, and the maintenance work is further made efficient. be able to.

  In the above description, the approval device 30 receives the work procedure manual data from the maintenance device 20, but the work procedure manual data created by the maintenance organization when the work procedure manual is created is sent to the work unit B37. You may make it register. That is, prior to the maintenance work, the maintenance organization registers the work procedure manual data in the procedure manual area B, and registers the work procedure manual number described in the work procedure manual in the ID area.

  Instead of the work procedure manual data, the maintenance device 20 sends only the work procedure manual number described in the work procedure manual data as information for identifying the maintenance work, that is, the work procedure manual, to the approval request. The approval device 30 can obtain the corresponding work procedure manual data by comparing the received work procedure manual number and the work procedure manual number in the ID area to identify the corresponding work part B37.

  In the above embodiment, the program of the present invention is executed as the program A of the processing unit 26A, and the execution procedure of the program of the present invention is included in the execution procedure of the program A. However, the program of the present invention does not operate only with the configuration of the program A of the processing unit 26A, and can operate on a computer having a configuration different from that shown in FIG. 2 as long as the necessary configuration is satisfied.

  The maintenance method of the present invention corresponds to a maintenance work execution method executed by the maintenance device 20 or the approval device 30 in the maintenance system of FIG. However, the maintenance method of the present invention is not limited to the configuration of the maintenance system of FIG. 2, and can be realized on a system having a configuration different from that of FIG. 2 as long as the necessary configuration is satisfied.
