Abstract
A pick-resistant lock system includes a locking means. The locking means includes a displacement sensor for sensing displacement so as to generate a displacement signal, the displacement sensor comprising a micro electromechanical gyroscope, a second counterpart, a second alarm, and a second control unit for receiving the displacement signal so as to start the alarm. A key includes a control switch, a second counterpart corresponding to the second counterpart, a second alarm, and a second control unit for receiving the displacement signal transmitted from the locking means so as to start the second alarm.
Claims20
A pick-resistant lock system comprising:
- a locking means comprising:
- a displacement sensor for sensing a displacement of an object so as to generate a displacement signal, the displacement sensor comprising:
- a micro electromechanical gyroscope, which generates the displacement signal when an angular velocity of the micro electromechanical gyroscope is larger than a predetermined threshold;
- a first counterpart;
- a first alarm;
- a first storage device storing an original displacement signal;
- and a first control unit receiving the displacement signal, starting the first alarm after comparing the displacement signal with the original displacement signal, and meanwhile transmitting the displacement signal to a second control unit;
- and a key comprising;
- a control switch;
- a second counterpart corresponding to the first counterpart for matching the key with the locking means;
- a second alarm;
- and
- the second control unit for receiving the displacement signal transmitted from the locking means so as to start the second alarm;
- wherein the locking means further comprises a first status indicator for indicating an actuating state, an off state, and a power shortage state of the locking means.
