The invention relates to a household garbage classified collection and intelligent supervision method and system and belongs to the technical field of intelligent environmental protection equipment. According to the technical scheme, a data communication and information management system comprises a central intelligent cloud platform, household classified garbage dumping reservation platforms, management platforms, an unmanned bookable garbage collection truck and a special classified garbage transport truck. The management platforms comprise a regional management platform, a sanitation station management platform, a classified garbage management platform, a classified garbage treatment plant management platform and a government management platform. By means of the household garbage classified collection and intelligent supervision method and system, data collection and sharing among the links including classification, feeding, collection, transport, statistics, supervision and the like of household garbage are realized, the manpower cost for regional garbage classified collection is lowered, fixed regional garbage collection points, garbage transfer stations and pollution to the surrounding environment are eliminated, the intermediate link of garbage clearance and the basic construction investment are reduced, the contradiction that early-period classification information and later-period transport processing information of household garbage are not consistent is solved, and the utilization rate of renewable resources is increased.
