1. An electronic lock device, comprising:
a lock mechanism that is controllable to switch between a locked state and an unlocked state;
an actuation mechanism that is connected to said lock mechanism and that is configured to actuate said lock mechanism to switch between the locked state and the unlocked state; and
a control unit that is connected to said actuation mechanism, and that includes a processor, and a current detection module for detecting an amount of electric current flowing through said actuation mechanism;
wherein:
during an operation in which said actuation mechanism is activated by said processor to start switching said lock mechanism from an original state, which is one of the locked state and the unlocked state, to an intended state, which is the other one of the locked state and the unlocked state, said current detection module is configured to continuously detect the amount of electric current flowing through said actuation mechanism;
in response to receipt of the amount of electric current, said processor is configured to determine whether the amount of electric current is greater than a predetermined threshold; and
when it is determined that the amount of electric current is greater than the predetermined threshold, said processor is configured to control said actuation mechanism to immediately switch said lock mechanism back to the original state, and to deactivate said actuation mechanism;
wherein said control unit is further configured to, when it is determined that the amount of electric current is greater than the predetermined threshold, initiate a checkup procedure that includes steps of:
a) controlling said actuation mechanism to switch said lock mechanism back to the original state;
b) controlling said actuation mechanism to start switching said lock mechanism to the intended state again, and receiving a present amount of electric current flowing through said actuation mechanism;
c) determining whether the present amount of electric current is still greater than the predetermined threshold; and
d) when it is determined that the present amount of electric current is still greater than the predetermined threshold, controlling said actuation mechanism to switch said lock mechanism back to the original state, and then deactivating said actuation mechanism.
