Description

technical field [0001] The invention relates to the field of smart home, in particular to an intelligent door lock system. Background technique [0002] The smart door lock system uses computer technology, electronic technology, precision machinery manufacturing technology, precision electromagnetic technology and smart card technology to realize the identification of cardholders entering and leaving the room, and to control whether the mechanical door lock is opened. Electronic door lock is a security product with a high level of security protection, suitable for dormitories, guest houses, hotels, high-end apartments, offices and other places with high security level requirements. The smart door lock system manages the door locks of each room and office through the door lock management software. With different hierarchical authorization management functions and permissions, the microcomputer in the lock can identify the legitimacy and level of the card, and make correspond...

AI Technical Summary

Problems solved by technology

The power supply circuit of the traditional smart door lock system uses many components, the circuit structure is complicated, the hardware cost is high, and it is inconvenient to maintain

In addition, because the power supply circuit of the traditional smart door lock system lacks corresponding circuit protection functions, such as: preventing interference signal functions, the safety and reliability of the circuit are poor
