Anti-theft door fingerprint control circuit

Abstract

The invention discloses a fingerprint control circuit applied to burglarproof doors. The fingerprint control circuit is characterized in that an intelligent terminal signal interaction end is connected with a controller signal interaction end; a controller fingerprint recognition signal end is connected with a fingerprint recognition circuit signal output end; a controller first position signal receiving end is connected with a first position sensor signal sending end; a first position sensor signal receiving contact is connected with a first touch block; a controller first operation signal end is connected with a first electric pushing rod signal receiving end; a controller second position signal receiving end is connected with a second position sensor signal sending end; a second position sensor signal receiving contact is connected with a second touch block; a controller second operation signal end is connected with a second electric pushing rod signal receiving end. The circuit is an organic whole; structures of the circuit cooperate with each other to complete identity recognition and authentication; the movement of the internal mechanical structures is controlled to complete the door opening process, so that the access security is ensured.

Description

technical field [0001] The invention relates to the field of electronic circuit control, in particular to a fingerprint control circuit for an anti-theft door. Background technique [0002] With the continuous advancement of science and technology, the application of biometric technology in community security systems is becoming more and more common, especially through fingerprint recognition technology to identify access control or home entry systems, thereby saving time and improving efficiency, but in the existing technology Existing technical issues include: [0003] 1. Since the identification of the fingerprint lock in the prior art adopts the matrix shape to set the fingerprint identification sensor chip, the fingerprint cannot be accurately collected; [0004] 2. During the analog-to-digital conversion process of the collected data, the conversion speed of the fingerprint data is slow, and the fingerprint needs to be verified multiple times, resulting in low efficie...
