The invention discloses a data profile dissemination channel method. The method is used for detecting data channel monitoring service of a power distribution automation training system dissemination channel to detect states of a map data teacher unit, map data student units, SCADA trainer units and SCADA student units to determine whether data dissemination channels are available or not. The power distribution automation training system dissemination channel comprises a graphic model library data dissemination channel and a teaching plane data dissemination channel. The graphic model library dissemination channel comprises a map data teacher unit direction feeder automation system and a data dissemination channel of a terminal hybrid simulation system, a map data teacher unit direction map data teacher unit data dissemination channel and an SCADA server data dissemination channel of a map data teacher unit direction power distribution automation training system. In the process of data dissemination, the data dissemination channels are adopted, so that a hybrid simulation system and CASE of all student systems are managed in a unified mode, preparations before classes are made, the student units are monitored through a student worktable, and information and files are obtained from the student units.
