Abstract
A fingerprint module, a fingerprint identification system, a control method and a smart lock. The fingerprint module includes: a fingerprint sensor, an MOC, and a key member, and the key member is connected to the fingerprint sensor. The key member is configured to generate an interrupt signal according to a touch operation of a user on the key member to wake up the main control unit, thereby reducing power consumption of the main control unit.
Claims20
A fingerprint module, connected to a main control unit, the fingerprint module comprising:
- a fingerprint sensor, a match on chip (MOC) and a key member, and the key member is connected to the fingerprint sensor;
- the fingerprint sensor is configured to collect fingerprint information of a verification target, and output the fingerprint information to the MOC;
- the MOC is configured to authenticate the fingerprint information, and output an authentication result to the main control unit;
- and
- the key member is configured to generate an interrupt signal according to a touch operation of a user on the key member, to wake up the main control unit.
A control method based on a fingerprint identification system, the fingerprint identification system including a main control unit and a fingerprint module, and the fingerprint module includes a fingerprint sensor, a match on chip (MOC) and a key member, and the key member is connected to the fingerprint sensor;
- and correspondingly, the control method comprising:
- generating, by the key member, an interrupt signal according to a touch operation of a user on the key member, to wake up the main control unit;
- controlling, by the main control unit, at least one of the fingerprint sensor or the MOC to power up;
- collecting, by the fingerprint sensor, fingerprint information of a verification target, and outputting the fingerprint information to the MOC;
- and
- authenticating, by the MOC, the fingerprint information and outputting an authentication result to the main control unit.
