A method for intelligently controlling a device, comprising: acquiring, by a portable controlling device, parameter information of a controlled device in a current state, wherein the parameter information is used for reflecting a current running state of the controlled device; generating, by the portable controlling device, a graphical interaction interface comprising the parameter information, and sending the graphical interaction interface in a form of a data stream to an interaction device for display; receiving, by the portable controlling device, an input event sent by the interaction device, wherein the input event is triggered by a user based on the parameter information displayed on the graphical interaction interface of the interaction device; parsing, by the portable controlling device, the input event to obtain a control instruction corresponding to the parameter information comprised in the graphical interaction interface; and sending, by the portable controlling device, the control instruction to the controlled device, so that the controlled device performs, in response to the control instruction, a control operation corresponding to the current running state of the controlled device, wherein the performing a control operation corresponding to the current running state of the controlled device comprises performing an adjustment corresponding to the parameter information comprised in the graphical interaction interface; wherein the portable controlling device is a plug-and-play device, and the portable controlling device is adapted to control the controlled device through an interface; and wherein before the acquiring, by the portable controlling device, parameter information of a controlled device in a current state, the method further comprises: sending, by the portable controlling device, a type acquiring instruction to the controlled device, and receiving type information of the controlled device which is sent by the controlled device in response to the type acquiring instruction, the type information of the controlled device include a device type, model information, or a device manufacturer of the controlled device; sending, by the portable controlling device, identity information of the portable controlling device and the type information of the controlled device to a cloud server, and receiving a device control service program, which matches with the type information of the controlled device and is sent by the cloud server after the cloud server determines through authentication that the identity information of the portable controlling device is valid; and controlling, by the portable controlling device, the device control service program matching with the type information of the controlled device to run on the portable controlling device, so as to trigger performing of the step of acquiring parameter information of a controlled device in a current state. acquiring, by a portable controlling device, parameter information of a controlled device in a current state, wherein the parameter information is used for reflecting a current running state of the controlled device;
