Abstract

The invention discloses a low-power-consumption anti-interference intelligent door lock and an awakening method.The door lock comprises a master control MCU, a touch panel, a fingerprint module and an NFC antenna circuit, the master control MCU is connected with the touch panel and the NFC antenna circuit through an IO interface, the master control MCU comprises a TKey touch key assembly and an NFC card detection assembly, and the touch panel is connected with the fingerprint module through an IO interface. The TKey touch key assembly is connected with the touch panel and the fingerprint module through IO interfaces, the NFC card detection assembly is connected with the NFC antenna circuit through an IO interface, the fingerprint module comprises a fingerprint sensor and a touch electrode, and fingerprint touch awakening is judged by scanning the TKey. Therefore, peripheral components and circuit design are reduced, and the cost is reduced; meanwhile, IO resource control is reduced, communication is not needed, initialization work is reduced, working time is saved, and power consumption is reduced; mutually independent multiple groups of power supplies are arranged in the chip, a shielding channel is added, the anti-interference capability is improved, the intelligent door lock performance is improved, and the power consumption of the door lock is reduced.

Description

technical field [0001] The invention relates to the technical field of intelligent door locks, in particular to an intelligent door lock with low power consumption and anti-interference and a wake-up method. Background technique [0002] In recent years, the safety awareness of the whole people has generally improved, the requirements for the informatization and intelligence of home life have been continuously improved, and new requirements have been put forward for the security system. Door locks have experienced metal keys to today's fingerprints, passwords, and card multi-functional smart locks. With the coming of the smart home era quietly, as the most popular part of the smart home field, the smart door lock market has developed rapidly in recent years. More and more users have begun to use smart door locks. [0003] With the development of smart home, the smart door lock industry has risen rapidly. As the entrance of smart home, the development of smart door lock has...
