Magnetic Door Lock Calibration for Accurate Locked-State Detection

The patent applies preliminary action by performing calibration operations before the door lock is put into service. The calibration process pre-establishes the magnetic field intensity characteristics for different door states (open, closed, locked) and stores reference values in a database. This preliminary calibration enables the door lock to automatically compensate for magnetic field interference during actual operation, maintaining detection precision while preserving automation.

The patent implements self-service by enabling the door lock to perform automatic calibration without requiring user intervention or expert knowledge. The system automatically collects magnetic field intensity data at different door states, processes the data through established algorithms, and stores the calibration results in a database. This self-calibrating capability eliminates the need for manual calibration operations while maintaining high detection accuracy.

The patent replaces manual mechanical calibration operations with an automated electronic system. Instead of requiring physical adjustment of components or manual data collection procedures, the system uses a sensor to automatically measure magnetic field intensity, a processor to analyze the data according to predetermined algorithms, and a database to store calibration results. This substitution of mechanical calibration with an electronic automated system reduces complexity while maintaining measurement precision.
