Fingerprint identification and door lock-combined alarm system
The invention relates to a fingerprint identification and door lock-combined alarm system. The objective of the invention is to the problem of frequent burglary. The fingerprint identification and door lock-combined alarm system is a family safety alarm system. With the family safety alarm system adopted, burglary can be found timely, and alarms can be rendered. A telephone line interface module is in network connection with a telephone; alarm telephone numbers are set through a man-machine interaction module, and fingerprints are verified through the man-machine interaction module, and the alarm telephone numbers and the fingerprints are stored in an information memory; a lock tongue state detection module is arranged in a door lock; when the lock tongue state detection module detects the retreat of a lock tongue, a timer starts timing; if someone inputs wrong fingerprints through a fingerprint identifier or does not input fingerprints in time t, a simulation on/off-hook control module controls and enables off-hook; a transmit-receive module is set to a signal tone detection CP mode; signal tones on a telephone line are detected; when the signal tones are dialing tones, the transmit-receive module is set to a double-audio frequency DTMF mode; the alarm telephone numbers are read from the information memory, and dialing alarming is carried out; and after dialing is completed, the transmit-receive module returns to the CP mode. The fingerprint identification and door lock-combined alarm system of the invention is used for indoor security alarming.
