A mechanical coded lock can comprise at least one code wheel, when a user sets a code, the number which the user wants to set on each code wheel is rotated to a corresponding position, and when the mechanical coded lock is opened, the code wheels are also rotated to enable the tooth positions of the numbers to be matched with the set code positions.

In this embodiment, the manner of establishing the correspondence between each digital tooth position on the cipher wheel and the voltage sampling value may be: and sequentially collecting the voltage values of the password wheel on the digital tooth positions to establish the corresponding relation between the voltage values and the digital tooth positions.

Specifically, because the resistance values of a plurality of divider resistors corresponding to the same password wheel are different, and the voltage values at two ends of the divider resistors connected with each digital tooth position on the password wheel are also different, the corresponding relation table of the voltage values and the digital tooth positions can be established by sequentially gating and collecting the voltage values of each password wheel on each digital tooth position.

And step 120, acquiring the voltage value of each password wheel when the mechanical lock is at the set password position.

In this embodiment, after reading the password of the mechanical lock, the following steps may be further performed: the password is sent to a terminal associated with the mechanical lock.

Specifically, the mechanical coded lock in the embodiment of the invention can be in communication connection with a terminal such as a mobile phone of a user, and after the password of the mechanical coded lock is read, the password can be sent to the terminal of the user through the communication connection, so that the user can conveniently check the set password. For example, when the user forgets the set password, the set password can be read through the mobile phone, and the lock can be unlocked without being broken.
