Method and system for implementing multi-terminal collaborative operation based on a projection mobile hotspot

摘要

The disclosure discloses a method and a system for implementing projection. The method comprises: connecting a router terminal having a file storage function with a projector device, establishing a projection local area network via the router terminal, and adding all collaborative terminals to the projection local area network; during projecting, establishing data synchronization between a first collaborative terminal that sends a projection file and the router terminal, and meanwhile controlling, by the router terminal, the access right of other collaborative terminals in the projection local area network on the projection file; when a second collaborative terminal needs to modify the content of the projection file, the router terminal stopping the data synchronization with the first collaborative terminal, and establishing data synchronization with the second collaborative terminal and meanwhile granting the access right of the projection file to the second collaborative terminal, so as to modify and project the projection file.
