Abstract

A maintenance assistance device includes a database in which maintenance assistance data is entered, an information obtaining unit to obtain, from a production facility, problem identification information indicating a problem having occurred in the production facility, an information retrieval unit to retrieve, from a plurality of pieces of maintenance assistance data entered in the database, maintenance assistance data corresponding to problem identification information obtained by the information obtaining unit, and a display control unit to display, on a display unit, a measure-taking method for a problem indicated by problem identification information obtained by the information obtaining unit, and a location of problem-causing factor, the location being the position of a target component on which the measure-taking method is implemented in the production facility, on the basis of maintenance assistance data retrieved by the information retrieval unit.

Dependent claims

A maintenance assistance device comprising:

a database in which maintenance assistance data is entered, the maintenance assistance data including installation position information indicating a position of each of components in a production facility, the components forming the production facility, measure-taking method information indicating a measure-taking method for a predicted problem in the production facility, problem identification information indicating a predicted problem in the production facility, and problem-causing factor information indicating a factor that causes occurrence of a predicted problem in the production facility;
information obtaining circuitry to obtain, from the production facility, problem identification information indicating a problem having occurred in the production facility;
information retrieval circuitry to retrieve, from a plurality of pieces of maintenance assistance data entered in the database, maintenance assistance data corresponding to problem identification information obtained by the information obtaining circuitry;
and
display control circuitry to display, on a display, a measure-taking method for a problem indicated by problem identification information obtained by the information obtaining circuitry, a location of problem-causing factor, the location being a position of a target component on which the measure-taking method is implemented in the production facility, and a factor that causes occurrence of a problem, on a basis of maintenance assistance data retrieved by the information retrieval circuitry, wherein
in the maintenance assistance data, a component ID is associated with the problem identification information, and
on a basis of the problem identification information obtained by the information obtaining circuitry, the information retrieval circuitry identifies a component assigned a component ID associated with the problem identification information, and identifies the measure-taking method for a problem related to an identified component, the factor that causes occurrence of a problem, and the production facility.
