The invention discloses a wireless control system. A first controller of the wireless control system can receive visible light signals from a user terminal and judge whether the user terminal is a local user or a casual user according to current user information in the visible light signals; if the user terminal is the local user, a first control unit executes local authentication of the user terminal; if the user terminal is the casual user, the first control unit notices a cloud server to conduct far-end authentication of the user terminal. In this way, since a visible light signal is adopted to conduct communication and data carried by the visible light signal can not be interfered and captured easily, communication safety is guaranteed; since the transmission distance of the visible light is large, the application range is wider; by constructing the structure of the system, the cloud server can share authentication treatment of a part of users from the first controller, the workload of the first controller is relieved, and high efficiency of operation of the system is ensured; besides, by the adoption of the wireless communication mode, the construction complexity and construction cost can be lowered.
