And a low frequency signal transmitter 101 of the door lock 100 for transmitting the door lock ID information of the door lock 100 by a low frequency signal. Specifically, the low-frequency signal in the present embodiment may refer to an electromagnetic wave signal having a signal frequency of 10 to 200 kHz. The door lock ID information is identification information of the door locks 100, and each door lock 100 has unique identification information. The low frequency signal transmitter 101 may load the door lock ID information in a low frequency signal and broadcast within a range of distances (e.g., within 2 meters around the door lock 101).
In an alternative implementation, the transmitted door lock ID information may be information obtained by encrypting the ID of the door lock. It should be noted that, in the present embodiment, a specific encryption method is not limited at all, as long as encryption can be implemented.
And the low-frequency wake-up receiver 201 of the key terminal 200 is used for receiving the low-frequency door lock ID information sent by the door lock 100 and waking up the key MCU 202. Specifically, the low frequency wake-up receiver 201 may include a low frequency wake-up receiving chip and an antenna. For example, the low frequency wake-up receiving chip may be any one of the MCP2030, AS3933, or AS 3932. Normally, the key MCU202 of the key fob 200 is in a sleep state to minimize power consumption of the key fob 200. When a user carries the key terminal 200 to approach the door lock 100, if the low frequency wake-up receiver 201 is located within the low frequency signal transmission range of the low frequency signal transmitter 101, the low frequency wake-up receiver 201 can receive the low frequency door lock ID information sent by the low frequency signal transmitter 101 and wake up the key MCU202 in sleep.
