Contactless electromechanical password lock based on Hall sensor

Abstract

The invention discloses a contactless electromechanical password lock based on a Hall sensor. The contactless electromechanical password lock comprises a microcontroller, a Hall sensor, a voice prompt circuit, a mechanical lock driving module and a mechanical lock. The microcontroller is connected with a Hall sensor module, a mechanical lock driving module, a voice prompt module and a CAN (control area network) bus interface unit, and used for system control; the Hall sensor module is used for magnetically responding and transmitting an induced signal to the microcontroller; the voice prompt module is used for voice prompt in the unlocking process; the CAN bus interface unit is used for transmitting unlocking information to a host computer by employing a CAN bus; and the mechanical lock driving module is used for driving the mechanical lock.

Description

technical field [0001] The invention relates to a combination lock, in particular to a non-contact electromechanical combination lock based on Hall sensors. Background technique [0002] Combination locks have been greatly developed with the advancement of science and technology, especially electronic combination locks, while the form of mechanical combination locks is relatively monotonous. Generally, the combination is set and opened by rotating the angle of the lock cylinder. In electronic combination locks, there are high-tech combination locks such as fingerprint locks and iris locks. Although the confidentiality of these combination locks has been improved, their stability is not very good and they are easily affected by external conditions. And these coded locks all have one thing in common, that is, they are all contact or quasi-contact, that is, the opener can see the lock device intuitively, and even the iris lock, which is a kind of contact coded lock...

AI Technical Summary

Problems solved by technology

In electronic combination locks, there are high-tech combination locks such as fingerprint locks and iris locks. Although the confidentiality of these combination locks has been improved, the stability is not very good, and they are easily affected by external conditions.

And these combination locks all have one thing in common, that is, they are all contact or contact-like, that is, the opener can see the lock device intuitively, and even the contact-type combination locks such as iris locks also have the same problem. If it is damaged, the password lock function will be invalid

[0003] Generally, the combination locks that appear at present cannot prevent violent damage. If there is a non-contact type, that is, the unlocker cannot directly touch the unlocking device, which effectively prevents violent damage.

Moreover, the current combination locks generally do not have real-time monitoring functions, which is unfavorable for some extremely confidential places.
