Abstract

The invention provides a data providing device, a data providing method and a device management system. The purpose is to reduce the modification workload in the service application by providing the data requesting source with service data conforming to the request of the data requesting source. It has: an on-site data acquisition unit that acquires on-site data related to on-site equipment; and a data provider that uses a service provider that utilizes on-site data as service data as a communication partner to send and receive information with a communication partner; a data provider Manage the information of conversion rules that define the relationship between site data and service data. When a data acquisition request is received from a service provider, the specified site data is acquired from the site data acquisition agency. If there is a discrepancy between the specifications of the service data, the acquired on-site data is converted into service data according to the conversion rule, and the converted data is sent to the service provider.

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 ...
