The invention provides an access control system for smart home. The access control system comprises a central control device, a face image collecting device, a fingerprint collecting device and an opening / closing driving device, wherein the central control device is respectively connected with the face image collecting device, the fingerprint collecting device and the opening / closing driving device and is used for recognizing the face image, judging the fingerprint, sending an opening / closing driving signal and managing the data; the face image collecting device is used for transmitting the shot digital image to the central control device; the fingerprint collecting device is used for collecting the fingerprint and judging and recognizing the living fingerprint; and the opening / closing driving device is used for responding to an opening / closing instruction of the central control device so as to open or close the door. The access control system for smart home provided by the invention combines face verification and fingerprint verification and can greatly promote the safety.
Description
technical field [0001] The invention relates to the field of smart home, in particular to an access control system for smart home. Background technique [0002] At present, with the improvement of people's living standards and family income, people's awareness of family and personal anti-theft has gradually increased, and home defense has become a concern of people. In recent years, people have begun to introduce electronic combination locks, radio frequency card identification systems, etc. Home anti-theft management, but these anti-theft systems have certain defects, the electronic combination lock will be cracked; the radio frequency card is easy to lose or damage, and the cost is high. [0003] In related technologies, image information with higher quality is obtained by preprocessing face images. Preprocessing the face image can eliminate the noise generated in the transmission process, and at the same time highlight the edge information of the face image, improving th...
