The invention relates to the technical field of brain-computer interfaces, and discloses a multi-interface fusion dynamic brain-computer interaction method based on frequency phase information multiplexing and a terminal. Based on an offline electroencephalogram experiment of a user, the most brain electrical stimulation classification number U of the user for achieving the optimal electroencephalogram stimulation classification effect, frequency-phase information of the brain electrical stimulation of the U classification and a first corresponding relation between the brain electrical stimulation of the U classification and electroencephalogram signal characteristics are obtained, and an interactive interface after multi-interface fusion is dynamically partitioned; the method comprises the following steps: acquiring Z sub-regions and brain control instructions included in each sub-region, distributing frequency-phase information of U-class brain electrical stimulation to each brain control instruction, acquiring brain electrical stimulation classification based on a first corresponding relation on the basis of brain electrical signal characteristics induced by a flicker rule of brain electrical stimulation corresponding to a certain brain control instruction when a user watches the brain control instruction, and determining a sub-region based on the user sight drop point coordinate, and outputting a brain control instruction in combination with the brain electrical stimulation classification and the determined sub-region. According to the invention, the brain-computer interaction work efficiency can be improved.

The utility model provides a refrigerator display assembly with a control function, which comprises a mounting plate, a connecting plate is fixedly connected above the mounting plate, an adjusting mechanism is tightly attached above the connecting plate, the adjusting mechanism comprises a holding piece, a pressing block is arranged inside the holding piece, and the pressing block is fixedly connected with the mounting plate. The outer wall of the pressing block is fixedly connected with a lengthening plate, the outer wall of the lengthening plate is fixedly connected with a clamping block, one end of the holding piece is provided with a protection pipe, and one end of the protection pipe is provided with a butt joint pipe. During use, an operator can press an internal pressing block to perform central operation, so that an internal lengthening plate and the clamping block perform central movement, and the holding piece is quickly pulled out through a connecting plate, so that the use force is relatively small during mounting and opening, and meanwhile, the abrasion to an internal connecting part caused by large-force operation is avoided.
