The invention creatively provides an acquisition and interaction platform for environmental and ecological multi-source heterogeneous big data of a power grid, which comprises a data collection systemwhich is used as an acquisition interface for multi-dimensional data input, filters impurity data, replans and arranges a message body structure, and provides a data basis for a subsequent original data resource pool; an original data resource pool which serves as an intermediate transition system and classifies and renames the same type of structural body information, wherien the named clustering message group classification corresponds to an output channel and is connected with an input interface of the data preprocessing system; and a data preprocessing system used for identifying catalogue categories defined in the data management system, carrying out type marking and data marking on the clustered message groups, and carrying out classified cleaning according to different marked databodies. According to the invention, an acquisition and interaction platform for multi-source heterogeneous big data is formed, and a formed new architecture can meet the requirement of combined display of various data types in the field of environmental protection and ecology.
