The invention provides a home smart energy management system architecture based on multi-cloud collaboration. The architecture provides a solution for data cooperative communication among household appliances, a home smart energy gateway, a household appliance manufacturer cloud platform and a cloud agent. According to the invention, the architecture of the household smart energy management systemis designed; Architecture design is carried out for file cooperation and an interaction mode during information interaction; the cross-cloud data transmission algorithm is optimized; Through the optimal flow-based cloud agent deployment mode, a cross-cloud data transmission optimization algorithm where multiple files are transmitted to one cloud and integrated cloud migration, an inter-agent dataflow scheduling algorithm based on first-come-first-served and shortest task priority principles and a file cooperative control mechanism based on a Hash collision processing mechanism, unified coordination control of intelligent household appliances under different scenes is realized, and a foundation is laid for intelligent scheduling control of household energy and formation of a cooperation control scheme.
