Remotely-controlled intelligent anti-theft door lock and password unlocking method

Abstract

The invention discloses a remotely-controlled intelligent anti-theft door lock and a password unlocking method. The remotely-controlled intelligent anti-theft door lock comprises a lock shell, a lock body, a bolt, a lock rod integrated with the bolt, a self-locking mechanism and an intelligent safety device which comprises a remote controller, a control circuit and an electromagnet, wherein the bolt is locked with the lock shell; and after the control circuit is electrically connected with the electromagnet, the control circuit controls the iron core of the electromagnet to be in contact with the lock rod to push the lock rod. A user sets unlocking passwords comprising multiple numbers for the intelligent safety device in advance, and each number corresponds to a corresponding time constant. The unlocking operation comprises the following steps: firstly, triggering the control circuit by using a key, and waiting for the time constant of the first password number; then, triggering the control circuit again, and waiting for the time constant of the second password number; repeating the processes until the complete passwords are input; and cutting off the power of the system to enable the intelligent safety device to fail, so that the door lock can be unlocked by using the key.

Description

technical field [0001] The utility model relates to a password unlocking method and an anti-theft door lock, in particular to an anti-theft door lock that can be opened by remote control, and can not destroy the door lock itself when the remote control fails, so that the victim can use the door The lock key is a method of inputting a password to open the door lock. Background technique [0002] At present, the known various password door locks are mainly composed of a keyboard, a micro-processing chip, a detection system, an alarm system, a motor, and an actuator. The mechanism works, but the structure of the actuator is complex, the current consumption is large, and the environmental conditions required for the entire lock are high, which affects the opening and anti-theft performance of the lock. Of course, there are also coded door locks that use the circuit to control the iron core of the electromagnet to achieve safe locking, but generally use a holding electromagnet. ...

Problems solved by technology

[0002] At present, the known various password door locks are mainly composed of a keyboard, a micro-processing chip, a detection system, an alarm system, a motor, and an actuator. The mechanism works, but the structure of the actuator is complex, the current consumption is large, and the environmental conditions required for the entire lock are high, which affects the opening and anti-theft performance of the lock.

Of course, there are also coded door locks that use the circuit to control the iron core of the electromagnet to achieve safe locking, but generally use a holding electromagnet. When the system fails (the battery is dead, the control board is faulty, etc.), the electromagnet will lock the door lock. , which brings inconvenience to users and also puts forward new requirements for the industry
