The invention discloses a shared toilet system under a cloud network. The system comprises a cloud control center; the cloud control center performs information interaction with a user through the network; toilet resource information monitoring is established under the cloud control center; toilet resources include social resources, non-profit public places and professional institutions; and the cloud control center is used for monitoring toilet resource information, establishing a real-time position information base and a route planning system, performing recommended shortest time and recommended shortest distance planning according to the position and the requirement of the user, and sending real-time planning information to the user. By establishing the shared system, the sharing of thetoilet resources is realized, so that the technical problem that the usage requirements cannot be met by public toilets can be effectively solved; and the shared mode is rich, the resources are wide,the mode is reasonable, and the existing resources can be effectively integrated, so that the resource utilization maximization is achieved, and the resource waste is avoided.
