Door lock control method and system

The invention discloses a door lock control method and a door lock control system. The method comprises the following steps: A, a mobile terminal acquires the facial image data and carries out feature extraction to form facial feature data to be sent to a server; B, the server receives the facial feature data and compares the facial feature data with preset feature template, and if consistent, sending an identification passing instruction to the mobile terminal; C, the mobile terminal receives the identification passing instruction and then generates a dynamically encrypted circuit connecting instruction and sending to a door lock control circuit board; D, the door lock control circuit board carries out handshaking checking on the dynamically encrypted circuit connecting instruction, and if the checking passes, controlling to connect an electronic door lock. According to the invention, the mobile terminal and the server are utilized to realize the facial identification technology and are organically combined with control on the electronic door lock, so as to realize the intelligent unlocking function with low cost; the system avoids the problem that common door locks and locks with magnetic card swiping function are easy to be duplicated, and improves the domestic antitheft security level.
