The invention discloses a multi-level integrated data exchange system oriented to regulation and control services. The multi-level integrated data exchange system comprises integrated data exchange service modules deployed in each safety zone and each plant station in a multi-level regulation and control mechanism, wherein each integrated data exchange service module is connected in a transverse direction and a longitudinal direction to form a transverse and longitudinal through data exchange channel, and provides a data interaction function for quasi-real-time/non-real-time services distributed in the multi-level regulation and control mechanism and all safety zones and plant stations. According to the multi-level integrated data exchange system, an integrated data exchange system framework which crosses regulation and control mechanisms, safety zones and platforms is established, and a data interaction operation mode with a task as the center is achieved, and data exchange tasks aremanaged and maintained in a unified mode.
