This utility model relates to the field of screen window lock technology, specifically disclosing a full-surface raised screen window lock, comprising: a lock body, a lifting block inside the lock body, a steel plate inside the lock body, a switch inside the lock body, a first compression spring fixedly connected inside the lock body, an abutment block inside the switch, a locking pin fixedly connected to the center of the bottom of the lifting block, two locking grooves inside the locking pin, a second compression spring fixedly connected to both sides of the bottom of the lifting block, an annular block fixedly connected to one side of the bottom of the switch, a circular groove inside the steel plate, and a blocking groove inside the base plate. This utility model, through the combined use of the switch, the first compression spring, the steel plate, the locking pin, the locking grooves, and the actuating annular groove, allows the screen window to be easily opened. Opening or closing the screen window can be achieved by pulling the lifting block back and forth, making the opening and closing of the screen window more intuitive and simple, and convenient for users.

The invention discloses an intelligent door and window control system, and relates to the field of intelligent home control. The system comprises a multi-modal data acquisition module, a multi-modal scene perception decision module, a door and window execution module, a user interaction module and a data storage module. The core innovation is a multi-modal scene perception decision-making module, and the multi-modal scene perception decision-making module realizes accurate control through three steps: preprocessing numeric type, behavioral type and state type data and extracting features; a user behavior-environment dynamic coupling model is constructed, the matching degree is calculated through a scene membership degree formula, and five types of core scenes are recognized; and finally, door and window opening and closing and locking instructions are generated according to the scene. The system breaks through the limitation of traditional single parameter decision, can dynamically adapt to user habits and environment changes, gives consideration to safety, practicability and economy, and effectively solves the problems of misjudgment and poor adaptability of a traditional system.
