Batch file transmission method and device between heterogeneous systems

The invention discloses a batch file transmission method and device between heterogeneous systems, and the method comprises the steps: a user strategy definition device receives a batch interaction request instruction submitted by a host application system, determines a server IP address and target interaction interface information, analyzes and simplifies service data to obtain simplified-structure service data, and generats a general data file; a data transmission device processes the batch interaction request instruction in the general data file according to a preset processing parameter to generate an interaction data file; a strategy analysis and execution device establishes a connection path with the target platform application system based on the server IP address and the target interaction interface information, restores the simplified structure service data, obtains complete structure service data, and generates a transmission data file; and a platform application system completes a data processing t
