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.
