Electronic key-based intelligent lock

Abstract

The invention discloses an electronic key-based intelligent lock which comprises a radio frequency module, an identification circuit module, a motor control module and an intelligent lock master controller, wherein the radio frequency module sends a radio frequency signal; the identification circuit module identifies the radio frequency signal after detecting the radio frequency signal, if the identification result shows that the radio frequency signal is authorized and allowed to pass, the intelligent lock master controller is notified, the intelligent lock master controller starts the motor to withdraw a blocking latch in a key hole, so that the electronic key can be rotated to unlock; if the identification result shows that the radio frequency signal is unauthorized or not identified and is not allowed to pass, the intelligent lock master controller is notified, the intelligent lock master controller keeps the blocking latch in the key hole, so as to prevent the electronic key from being rotated to unlock. The electronic key-based intelligent lock provided by the invention changes a mechanical key implanted with a radio frequency chip into the electronic key, and sends the radio frequency signal through a chip; each electronic key has an independent ID number; whether the electronic key can be rotated to unlock can be determined by verifying whether a use authority is obtained, so that the security is high.

Description

technical field [0001] The invention belongs to the technical field of electronic door locks, and relates to an electronic key-based intelligent lock. Background technique [0002] Smart locks are different from traditional mechanical locks. They are more intelligent locks in terms of user identification, security, and management. They are the executive components for locking doors in the access control system. Different from ordinary mechanical locks, the smart lock has an automatic electronic induction locking system. When it automatically senses that the door is closed, the system will automatically lock. Smart locks can unlock the door through fingerprints, touch screens, and cards. In the security environment of ordinary residential areas, the general door lock handle opening method cannot ensure sufficient safety performance. It is easy to drill a small hole from the outside of the door and then use a wire to turn the handle to open the door. Many smart locks are gua...

Problems solved by technology

While the current smart lock uses mechanical keys, it also adds the functions of fingerprint recognition, iris recognition, and password recognition. Since the relevant national standards stipulate that the smart lock needs to retain the unlocking function of the mechanical key, but the mechanical key is often easily lost, copied and Illegal embezzlement, leaving a greater security risk
