Description

  The present invention relates to an in-facility inspection / repair work support system that supports inspection / repair work for a predetermined device installed in a facility (for example, a power plant).

  Conventionally, for example, in a facility such as a power plant owned by an electric power company or the like, a plurality of valves are scattered in each place. When repairing peripheral devices including these valves or disconnecting the system, for example, it is necessary to go to the site in order to operate the corresponding valves, and to find the target valve from among the scattered valves. I wasted my time walking around the boiler and turbine building for a long time.

  In addition, for example, in order to turn off the power of the motorized valve and to search for the power source location in the electric room, it takes a considerable amount of time because it goes back and forth in a large electric room. Therefore, for example, even when an urgent operation occurs due to a serious accident, there is a high possibility of spending time to search for the corresponding valve and shifting to a large disaster (for example, a power failure accident).

  As described above, in the conventional power plant, the location of the valve to be operated is not known, for example, it takes time to search for the valve to be operated in the field, or the power supply location of the motorized valve is searched in the electric room Therefore, there was a problem that it took time. Furthermore, even when urgent work that leads to a disaster occurs, it takes time from the operation time to the end of the valve to be operated, so there is a concern that a large disaster may occur. It was.

  Under the circumstances as described above, the location of a target device (for example, a valve or a power source at a power plant) installed in a facility or the like can be easily searched, for example, installed in a power plant. It has been desired to construct a system that can be efficiently used for inspection and repair work on predetermined equipment.

  In addition, as a technology related to the inspection and repair of equipment installed in facilities, for example, a valve maintenance management support system that can select the maintenance implementation time of each valve that equalizes the risk index in the entire piping system (patent document However, since this system is economical, it cannot be applied as it is to a system for efficiently supporting peripheral devices including valves as inspection and repair work.
