The invention discloses a wireless access control system based on finger vein recognition, and relates to the field of intelligent buildings. The wireless access control system comprises a DSP (Digital Signal Processor), a finger vein image acquisition and recognition device, an FLASH memory, an SDRAM (Synchronous Dynamic Random Access Memory), an LCD display module, a relay and an electromagnetic lock, wherein the DSP is connected with the relay, a keyboard module, the LCD display module, the FLASH memory and the SDRAM; the DSP is in communication connection with the finger vein image acquisition and recognition device through a wireless transmission module; the electromagnetic lock is connected with the relay. The community access control system is opened only through a right finger vein image, so that the safety of the community access control system is increased, and a user uses the wireless access control system conveniently, without carrying a magnetic card or remembering the password.
Description
[0001] technical field [0002] The invention relates to the field of intelligent buildings, in particular to a wireless access control system based on finger vein recognition. Background technique [0003] With the continuous improvement of people's living standards, the value of daily necessities is also increasing, and people are paying more and more attention to anti-theft measures. With the diversification of crime methods, traditional mechanical locks can no longer ensure security. Many residential areas are equipped with magnetically controlled anti-theft doors downstairs, and many anti-theft doors can be opened by entering a password or a magnetic card to ensure the safety of the anti-theft. But in life, the password is easy to leak, and the magnetic card will also be lost, which adds uncertain factors to the security of the anti-theft door and brings safety hazards to our lives. [0004] Currently commonly used identification technologies include fingerprint recog...
