Description

  The present invention relates to a maintenance history management system and a maintenance history management method for creating and registering a maintenance history of equipment and the like installed in various facilities.

  Some companies maintain various types of equipment. For example, an electric power company has a power plant and an electric plant, and maintains various facilities installed in them. Electric power companies maintain these facilities to maintain various facilities. In this case, a maintenance history in which the contents of maintenance and work days are recorded is registered and accumulated for later verification and the like. When registering the maintenance history, the person in charge inputs the contents of maintenance, the date of work, etc. into the computer based on the maintenance results of the work report created by the person in charge of maintenance. The maintenance history is registered by such manual work.

  On the other hand, there is also a system that automatically creates a maintenance history (see, for example, Patent Document 1). In this system, the maintenance history is divided into a large classification, a middle classification, and a small classification and recorded in a database. For example, the number of facilities constituting a thermal power plant is enormous. For this reason, in this system, facilities are classified and managed hierarchically. In this case, an equipment group which is a large classification is provided and classified as a turbine, a boiler, a generator, or the like. In addition, equipment is provided as a medium classification under the equipment group, and a turbine is classified as a high pressure turbine, a medium pressure turbine, or a low pressure turbine. Furthermore, a part is provided as a small classification under the equipment, and if it is a high-pressure turbine, it is classified into a moving blade, a stationary blade, and a shaft. If the maintenance history is classified by such hierarchization, management of the accumulated maintenance history becomes easy.
