Description

  The present invention relates to an on-site work management system that makes it possible to confirm completion of work of disassembly inspection maintenance work related to equipment and equipment to be carried out for periodic inspection of a plant and to view the contents of work performed.

  For example, in maintenance work for equipment in a large-scale plant such as a nuclear power plant, the plant operating company in advance discusses with a contractor such as a plant maker, etc. The contractor carries out the work in accordance with predetermined work procedures and procedures. In this case, the important points during the work are defined as the presence of supervisors belonging to the plant operation company, and the work results such as inspections are recorded in the quality records of the work manual, etc. The work is completed by obtaining a qualitative record and receiving approval from the supervisor.

  Such work execution records are created in paper format and stored for a predetermined year and month. And it is used as an overhaul inspection plan related to the target device parts from the next time and a history check when nonconformity occurs.

  In such a work completion confirmation method, only qualitative information is recorded on the evidence for the work performed, so that it is difficult to confirm the detailed contents. For example, when confirming whether or not bolt tightening during pump assembly is performed in a well-balanced manner according to the procedure, only qualitative information such as pass / fail or tightened torque value is recorded. It is difficult to confirm details when attempting to confirm the details.

  In addition, because work is carried out based on the contractor's and supervisor's trust relationships and tacit understanding, there is still a possibility that the criteria for completion of work may be ambiguous due to personal experience and technical level differences. Yes. Furthermore, since the implementation records stored in paper are only qualitative information, no method for quantitative analysis or re-evaluation after completion of construction or assembly is not provided.

  In addition, it is left to the contractor's judgment except for the witnesses, and it is very difficult to confirm whether the planned work has been carried out at the planned location according to the planned procedure. The possibility of human error such as is left. There may be a plan to increase the number of witnesses to cope with these, but it is not practical from the viewpoint of limited supervisors and construction period, and even if it can be realized, it takes time to move to multiple witnessing places. Therefore, it was an obstacle to efficient work.

Therefore, in-plant information communication system (see Patent Document 1) designed to improve work efficiency and reduce the burden on workers by implementing two-way communication between the work site and the control room in the plant, and inspection and maintenance work. There is a plant maintenance work support system (see, for example, Patent Document 2) that can share necessary information between a site and an office.
Japanese Patent No. 3106107 JP-A-11-202904

  However, even if a method of digitizing and sharing the status of on-site work between offices instead of paper is adopted, the overhaul and maintenance work related to the relevant equipment is selected without any omissions or omissions. There is no means to check in correspondence with the work procedure under construction. Normally, more than a dozen orders of work are carried out in parallel every day. For example, there is a possibility that it is not possible to immediately confirm whether or not the site work shared in the office is the target work. is there. In addition, consistent construction and work history become difficult, and lack of transparency as evidence. Furthermore, in a large-scale plant such as a nuclear power plant, there are cases where a large number of valves / instruments having similar / same structures are simultaneously operated, and the possibility of misjudgment remains.

  Even if video, audio, vibration, sound, equipment status, and inspection / measurement data (hereinafter referred to as on-site information) related to overhaul and maintenance of equipment at the site are obtained, it can be confirmed correctly according to the work procedure. There is no provision for checking whether this is done.

  Furthermore, no means for quantitatively analyzing and evaluating the field information related to the overhaul work of the obtained equipment is provided after the fact. For example, it is possible to compare the collection time of each data and link the connection between each data individually, but it takes a huge amount of labor, and even if it is individually linked in the human system, it is erroneous. The possibility of judgment remained. Conventionally, a similar system using a multipoint video conference system that transmits and receives audio data and video data has been provided. However, although it is possible to record actually transmitted and received data, it is transmitted and received. There is no established mechanism for automatically extracting, recording and organizing on-site information data important for maintenance and monitoring related to on-site work at a plant and confirming whether or not it can be carried out according to a predetermined work procedure.

  In addition, it provides a means to disclose the status of completion of overhaul and maintenance work of facility equipment on site to users of plant management companies and construction contractors who are responsible for other work related to the work concerned, and to make it useful for related work. It is not disclosed, and it is disclosed to the general users including local governments and public institutions where the plant is located, in a timely and complete manner, and shows the soundness of the plant and the transparency of maintenance work such as periodic inspections. No means are provided.

  The purpose of the present invention is to be able to appropriately select the field work of the overhaul and maintenance work related to the equipment and equipment to be carried out for the periodic inspection of the plant, perform the analysis and re-evaluation after the work is completed, and can disclose the completion status of these works It is to provide a management system.

  The field work management system of the present invention includes a construction procedure database that stores construction procedure information on overhaul inspection and maintenance work related to equipment that is carried out for periodic inspection of the plant, and construction work related to the work that is to be carried out in this periodic inspection.
