The invention discloses an unmanned intelligent warehouse system based on a robot, and belongs to the technical field of intelligent warehouses. The warehouse system comprises a central server, a warehouse robot and an emergency robot, any two of the central server, warehouse robot and emergency robot are in bi-directional signal connection with each other, the central server comprises a multi-robot communication module, a multi-robot scheduling and planning module and a warehouse state collecting and detecting module, wherein the warehouse robot comprises a main control module, an obstacle detection module, a two-dimension code reading module, a radio frequency reading module, a wireless communication module, a map storing and positioning module and a non-contact charging and receiving module. Fast and safe non-contact charging for the warehouse robot can be achieved, fire potential caused by contact charging of the robot is avoided, meanwhile, the emergency robot is introduced, theefficiency and safety of the warehouse can be greatly improved, and meanwhile, the processing and response speed for a burst condition can be improved.
