When the user 1000 approaches the door body 1 or the smart door lock 10, the detection signal 101 can reach the external object 1000 and return. The receiver 112 is configured to receive the detection signal 101 returned by the user 1000 and generate a corresponding first distance signal. When the first distance signal indicates that the user 1000 is within the detection range, the control unit 13 may control the biometric detection module 12 to turn on and perform biometric detection, such as, but not limited to, collecting facial features for the user and identification. When the first distance signal indicates that the user 1000 is not within the detection range, or when the receiver 112 fails to receive the detection signal 101 returned by the user 1000, the biometric detection module 12 does not work. Optionally, in some embodiments. The detection signal 101 can be infrared light or near-infrared light, the transmitter 111 can be an infrared emitting diode, and the receiver 112 can be an infrared receiving diode. The transmitter 111 and the receiver 112 may be integrated in one chip or separately provided in different chips.

The biometric detection module 12 can be used to detect and identify the two-dimensional and/or three-dimensional biometric information of the user 1000 .

After the user 1000 manually closes the door lock of the door body 1 (ie, after the user 1000 locks the door), obviously, the user 1000 is located within the detection range of the smart door lock 10 at this time. The detection unit 11 works and detects that the user 1000 is out of the detection range. When it is not detected that the user 1000 leaves the detection range (the user 1000 is not within the detection range), the biometric detection module 12 does not start biometric detection. When it is detected that the user leaves the detection range and then the user enters the detection range, the biometric detection module 12 starts biometric detection. Optionally, in some embodiments, the transmitter 111 may transmit the detection signal 101 at a preset period, if the receiver 112 receives the detection returned by the user 1000 within the detection range within each period of time If the signal 101 is present, it is determined that the user 1000 is within the detection range and has not left. At this time, the control unit 13 will not control the biometric detection module 12 to turn on.

When the user 1000 enters the detection range from the outside or enters the detection range again after leaving the detection range, the receiver 112 of the detection unit 11 receives the detection signal 101 returned by the user 1000 located in the detection range, and generates a corresponding first distance signal, The control unit 13 controls the biometric detection module 12 to turn on according to the first distance signal to perform biometric detection. For example, but not limited to, face detection and recognition of the user 1000 is performed. It can be understood that, since the detection signal 101 reaches the user 1000 after being sent from the transmitter 111, and then returns to be received by the receiver 112 to generate the first distance signal, the magnitude (or strength) of the first distance signal is different from the user 1000 and the user 1000. The distance between the smart door lock 10 or the door body 1 is related. According to the first distance signal, the control unit 13 can control the biometric detection module 12 to work, or the control unit 13 can control the biometric detection module 12 to stop working. Optionally, in some embodiments, the control unit 13 may be a control circuit, a microprocessor, a microcontroller, etc., or the control unit 13 may include an executable logic program. Those skilled in the art can understand that this application does not limit it.

It can be understood that after the user 1000 manually closes the door lock of the door body 1, it may not necessarily leave the detection range of the smart door lock 10 immediately. At this time, the detection unit 11 detects whether the user leaves the detection range, and when the user 1000 has not left the detection range By not enabling biometric detection and identification, it can effectively prevent the user 1000 from opening the smart door lock 10 after just locking the door and passing the biometric detection.
