Smart interlock system and working method thereof

A smart interlock system, comprising a lock (1), an unlocking device (2) and a logic generator (3), characterized in that:

• the logic generator (3) comprises a logic generation module and a logic communication module;
• the logic generation module generates identity identification logic and state identification logic of the lock, and the identity identification logic and state identification logic are sent to the unlocking device (2) through the logic communication module;
• the unlocking device (2) comprises an unlocking module, an identity identifying module and a communication module for starting a lock head;
• the lock (1) comprises a lock tongue (102), a lock head (106) and an identity and state conversion module (104);
• the lock head (106) is associated with the lock tongue (102) and drives the lock tongue (102) to move;
• while in motion, the lock tongue (102) has more than two set positions and intermediate positions between set positions;
• the identity and state conversion module (104) converts information of change of position of the lock tongue (102) into identity label information of the lock, and then transmits the identity label information of the lock to the unlocking device (2) upon insertion of the unlocking module into lock (1);
• the identity identifying module of the unlocking device (2) identifies the identity of the lock (1), receives the identity label information of the lock which is transmitted by the identity and state conversion module (104) of the lock, identifies the state of the lock tongue (102), and judges whether the process of unlocking shall be performed or not according to the identity identification logic and state identification logic of the lock, which are received from the logic generator (3).
