Abstract

The invention provides a data providing apparatus, a data providing method and an equipment management system. An object is to reduce modification workload in a service application by providing service data to a data request source in accordance with a request of the data request source. The data providing apparatus includes a field data acquisition unit configured to acquire field data relating to field equipment, and a data providing unit configured to transmit and receive information to and from a service providing unit, the service providing unit being a communication target and configuredto use the field data as service data, in which the data providing unit manages information on a conversion rule defining a relationship between the field data and the service data, acquires the field data specified in a data acquisition request from the service providing unit, from the field data acquisition unit, converts the acquired field data to service data according to the conversion rulewhen there is a difference between a specification of the field data and a specification of the service data, and transmits the data obtained by the conversion to the service providing unit.

Description

technical field [0001] The present invention relates to a data providing device, a data providing method, and an equipment management system. Background technique [0002] In recent years, for the purpose of providing services utilizing big data, for example, data management systems capable of collectively managing data collected from factory equipment or field devices (hereinafter referred to as field data) have been provided. [0003] The process of visualizing the amount of electric power measured in the factory or obtaining the operation rate from the production number of products for each production line is called "service". Such a service is provided to the user by, for example, a service device constituted by a Web server. [0004] The service device manages each site data by associating explanatory information such as the meaning and reading method of the site data with different types and structures, so that the service device can provide users with services using ...
