Face-discrimination keyhole-free alarm burglar-proof door lock

Abstract

The invention relates to a human face identification non-lockhole alarm safe-guard door lock and belongs to the safe-guard door lockset field. The technical proposal of the invention is that: an infrared human face identification electronic control circuit consists of a digital signal processor DSP, a synchronous dynamic random access memory SDRAM, a flash memory FLASH, a horn, a key, a motor controller, a miniature direct current motor, a power source, an infrared camera shooting module which captures human face images, infrared transmitting and receiving diode and photodiode which is used for detection, an infrared light-emitting diode set which is taken as a fixed light source, a liquid crystal screen and a voice codec; a human face identification module is arranged inside the DSP, respectively connected with the infrared camera shooting module, the SDRAM, the FLASH and the liquid crystal screen through an external bus, and connected with the voice codec through a multi-channel buffer serial port; the voice codec is connected with the horn and connected with the infrared light-emitting diode set, the key and the motor controller through IO interfaces; the motor controller is connected with the miniature direct current motor which controls a clutch pin. The invention adopts infrared human face identification and has no lockhole, and performances are stable and reliable.

Description

technical field [0001] The invention relates to an alarm anti-theft door lock, in particular to an alarm anti-theft door lock without a keyhole through infrared face recognition, which belongs to the field of anti-theft door locks. Background technique [0002] Anti-theft doors have entered my country's urban families on a large scale since the 1990s, and are now quite popular. Almost every urban family has an anti-theft door, and the anti-theft door lock is the core key component that directly affects the security of the anti-theft door. The national standard stipulates that the anti-technical opening time of Class A anti-theft door locks should not be less than 1 minute; the anti-technical opening time of Class B anti-theft door locks should not be less than 5 minutes. Although the above-mentioned standards are already very low, most of the anti-theft doors on the market still cannot reach them, and they can be opened easily and technically within tens of seconds. In rece...

Problems solved by technology

Patent 200420023559.8 uses a digital signal processor DSP as the chip, which makes embedded face recognition possible, but fails to solve the problem that the performance of face recognition is greatly affected by visible light, and cannot be applied to the field of high-security anti-theft doors
