Abstract

The present invention provides an optical door lock safety recognition system, which is positioned a bar code pattern on a surface of a key and to match with a door lock apparatus for practicing. There is an electromagnetic valve arranged within the door lock apparatus to curb a bayonet for limiting the movement of the lock head. There is a photography module is positioned at an outside of the notch channel and comprises a light emitting element and a photo sensor element so as to utilize the infrared rays to scan a bar code pattern of the key to form an output of a corresponding analog signal. A signal switch circuit is to transfer the analog signal into a plus signal to a microprocessor. The microprocessor is to transfer the plus into an output of a decoded signal to a control end so as to perform a comparison and a storage of the decoded signal and to transmit a order to the microprocessor in accordance with a comparison result and to decide if a conductive signal is transmitted to the electromagnetic valve in accordance with the order to lift the curbing of the bayonet. Hence, the present invention provides with advantages of low cost, assembling easily, and easy operation for users.
