The invention discloses an IEC61970 (international electrotechnical commission 61970) CIM (common information model) data query access method, and relates to the technical field of data transmission. The method comprises the following steps of (a) providing a query object, wherein the query object is any source of a model; (b) searching for resource information in a file to obtain a query result; (c) enabling the query result to correspond to the model. According to the method, the data of the model is acquired by direct file query, so that the access efficiency is improved; the model is stored in an RDF (resource description framework) file, so that maintenance is more facilitated, and the flexibility is improved; the method is easy to implement, clear in logic and high in packaging performance and maintainability, the development efficiency can be improved by twice to four times, resources can be saved, and the development and maintenance cost is lowered.
