BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a maintenance work support system comprising a plurality of information processing apparatuses for supporting a maintenance work of a plant, and more particularly, to a maintenance work including a repair, an inspection, and the like performed in a periodic inspection of a plant. The present invention relates to a plant maintenance work support system that supports work in terms of providing and exchanging information efficiently.

[0002] The present invention is not limited to a support system for periodic inspection work of a nuclear power plant, but for the sake of easy understanding, the following description will be made with the periodic inspection work of a nuclear power plant in mind. .

[0003]

2. Description of the Related Art In a nuclear power plant, maintenance work is periodically performed in order to generate power safely. This maintenance work consists of numerous and numerous maintenance work items such as equipment inspection, repair, replacement of deteriorated parts, etc. (One maintenance work item is a series of closely related maintenance work performed for one maintenance purpose. ) Maintenance work. Usually, all of these maintenance operations need to be completed within a certain period during which the plant is stopped, so that a plurality of maintenance operations are performed in a complicated manner. In addition, each maintenance operation needs to be performed in a certain order, that is, one maintenance operation must be completed before another, and safety must be ensured before starting the operation. Certain preparations must be completed for etc.

[0004] Under the circumstances described above, in order to carry out maintenance work on a plant such as a nuclear power plant, a maintenance work plan is made in advance, and the progress of the maintenance work actually performed during the periodical inspection is recorded and managed. In addition, process management must be performed so that each maintenance operation can be performed safely and without delay.
For this reason, a plant maintenance work support system using a computer (computer) has conventionally been used.

FIG. 13 shows a configuration of a conventional maintenance work support system. As shown in FIG. 13, a conventional maintenance work support system 31 includes a work evaluation unit 32, a scheduled maintenance work storage unit 33, a maintenance work recording unit 34, and an evaluation database 3.
5 and a man-machine interface 36.

[0006] The work evaluation section 32 is a central information processing means of the maintenance work support system 31, and supports the maintenance work.

The scheduled maintenance work storage unit 33 is a means for storing a maintenance work plan of the entire plant.

The maintenance work recording section 34 is means for recording the progress of the actual maintenance work.

The evaluation database 35 is a means for managing evaluation criteria for the feasibility of maintenance work. The term "database" refers to systematically managed data itself, a software program that manages search, update, and addition of data, and a storage device that stores data and software programs. And

The man-machine interface 36 serves as an interface between the maintenance work support system 31 and a user. The “interface” is a general term for means for exchanging requests and answers at the boundary between the information processing apparatus and the user.

In the conventional maintenance work support system 31, when an operator performs a predetermined maintenance work, an inquiry is made to an operator (administrator) of the maintenance work support system 31.
In response to the inquiry, the administrator inputs the maintenance work through the man-machine interface 36, and the work evaluation unit 32 refers to the maintenance scheduled work storage unit 33 to check whether the maintenance work is scheduled, Further, the feasibility of the maintenance work is determined and evaluated with reference to the evaluation database 35. As a result, if the work can be performed, the fact that the work can be performed is displayed or output via the man-machine interface 36.

When the worker completes the predetermined maintenance work, the operator (administrator) of the maintenance work support system 31
And the progress of the maintenance work is recorded in the maintenance work recording unit 34 by the operator (administrator).

Accordingly, the maintenance work support system 31 can manage whether or not the maintenance work can be performed and manage the progress of the maintenance work.

[0014]

However, the above-mentioned conventional maintenance work support system is effective in improving the efficiency of process management, efficiently providing and exchanging information necessary for maintenance work, and the efficiency of communication between workers and operators. There was still room for improvement in terms of commercialization.

For example, in terms of process management, a worker who has performed maintenance work at a work site of a plant enters a telephone or the like at a location where a maintenance work support system is installed, and a system operator assists the maintenance work. It was necessary to input the progress of maintenance work into the system. For this reason, the operator in the central control room of the plant cannot grasp the actual progress of the maintenance work until the input of the maintenance work progress is completed, and immediately activates the on-site equipment according to the progress of the maintenance work. For example, we could not prepare for the next maintenance work.

Further, since information on the operation of the on-site equipment by the above-mentioned operator was not immediately transmitted to the worker, the worker standing by at the worker waiting place could check the progress of the regular inspection work and the preparation of the plant equipment. I could not be dispatched to the site in a timely manner according to the situation. Further, in conventional plant maintenance work, it has been difficult to efficiently provide information necessary for maintenance work to workers when necessary.

Specifically, conventionally, since an enormous amount of document data such as a device inspection history and a device specification has been brought to the site, the original working space of the worker may be narrowed. Also, when referring to a large document with a large amount of information, all workers use the same document at once to fold and use the document so as not to obstruct the work space. I couldn't do that.

In addition, the document material may be contaminated with radioactivity.

Also, since the work result is recorded in the field, the paper on which the work results are recorded cannot be directly attached to the work report. Therefore, it is necessary to rewrite the work after the work is completed. In addition, there is a possibility that a transcription error may occur as well as a burden on the operator.

In addition, in terms of tool management, the conventional maintenance work support system cannot provide sufficient support.

That is, in the conventional tool management, the number and type of tools are visually checked using a checklist of tools written on paper. At times, he judged that he had made a mistake, and eventually left his tools on the site.

In view of the problems of the above-mentioned conventional plant maintenance work support system, the problem to be solved by the present invention is that the process management of the maintenance work can be performed efficiently, and the data and drawings required at the maintenance site can be obtained. It is an object of the present invention to provide a maintenance work support system which can be provided with good timing, can perform tool management reliably and efficiently, and can maintain a high level of communication between workers.

The sequential execution feasibility check, execution and recording of the above maintenance work will be described below using specific examples.

For example, it is assumed that maintenance work items, work procedures, and work precautions are stored in the maintenance work database 10 in the form of a table shown in FIG. In a state where the portable computer 3 is connected to the host computer 2 via the data communication terminal 5, the maintenance work item “pump disassembly and inspection preparation” is provided from the host-side man-machine interface 12 or the portable computer-side man-machine interface 18 before starting the work. ”And“ pump casing cover removal ”, the work evaluation unit 6 of the host computer 2 refers to the maintenance scheduled work storage unit 7 to check the work schedule of the maintenance work, and outputs the confirmation result to the portable computer 3. Send to If the work is scheduled to be performed, the work procedure and precautions for the work “preparation for pump disassembly and inspection” and “removal of the pump casing cover” in the maintenance work database 10 are transmitted to the portable computer 3 at the same time.

At the work site, while the portable computer 3 is connected to the host computer 2 via the data communication terminal 5, the operator operates the work item “pump disassembly check preparation” via the portable computer side man-machine interface 18. Is transmitted to the host computer 2 via the data communication terminal 5 and stored in the maintenance work recording unit 8.

On the other hand, the work evaluation section 6 refers to an evaluation criterion for “preparation for pump disassembly and inspection” in the evaluation database 9 in order to evaluate the feasibility of the maintenance work “preparation for pump disassembly and inspection”.

In evaluating the feasibility of the maintenance work,
When the plant state (equipment state) corresponding to the work item transmitted from the portable computer 3 in the table of the evaluation database 9 as illustrated in FIG. 3 matches the equipment state of the plant data of the plant, the work can be executed. If they are different, it is determined that the work cannot be executed.

For example, when the maintenance work item “preparation for pump disassembly and inspection” is sent from the portable computer 3, the state of the pump, the pump discharge valve, the pump inlet valve, the vent valve, and the drain valve in the plant data is changed as shown in FIG. And the pump is operating, the pump discharge valve is open, the pump inlet valve is open, the vent valve is closed, and the drain valve is closed. In this case, the work evaluation unit 6 determines that “preparation for pump overhaul” is not executable.
