Description
Technical field
The present invention relates to a kind of control method of the encrypted electronic lock based on infrared array and system, belong to smart home row
The field of prevention of a safety technology of industry.
Background technology
Door lock must have safety, stability as safety precaution product.Nowadays, the producer of some production locks is at itself
On the theftproof performance of lock, without any progress, for commercial object, only making an issue of in appearance in lock, change key shaped
Shape, purposely makes a mystery of simple things, and blinds consumer, even might as well most ancient, simple padlock on the theftproof performance of these locks.Sending out from lock
Exhibition sees that want the unlatching that can prevent skeleton key, the manufacturing process of lock will be especially complex in history, and manufacturing cost can ten several times
Increase, meanwhile, the performance of its anti-violence damage can also be substantially reduced, and lockset manufacturing is perplexed by this problem always.
So far, just really safety is the thing that consumers in general are concerned about the most to select which type of lock.But main flow is several in the market
Lock has various shortcomings：
1. mechanical lock：Due to its low price so being widely used by masses, but house robbery event emerges in an endless stream now,
Most theft gangs just can open door in several seconds using so-called MASTERKRY, easily get in；And mechanical lock key is easy
Be replicated, if running into the similar situation that key is used alone to part-timer, there is very big potential safety hazard；
2. Fingerprint Lock：Although the advantage being replicated in distress, it is easy to there is expensive, power supply fragile with electronic component in which
The shortcomings of breaking down, and temperature is not low easy to identify；
3. remote-controlled lock：Most of automobiles are all suitable for remote-controlled lock, but occur such a special steal in-car property handss
Method：The signal sent using remote control during car owner's car locking, car thief is where close using special instrument interference remote control
Signal, then opens car door and steals property.
Electronic lock is the important electronic installation for constituting public safety crime prevention system.With science and technology development, some with
Chip starts to occur for the SCM Based electronic lock of core, and the electronic lock of this type is usually to adopt electronic circuit control
System, using electric magnet (or micromachine) and lock body as the electromechanical integration safety of actuator.But existing electronics
Coded lock, is particularly applied to the electronic lock of public place, and its security and stability is still poor, such as once telling which by password
, will there is the risk of password leakage in other people.
Content of the invention
It is an object of the invention to, there is provided control method and system that a kind of encrypted electronic based on infrared array is locked, it
Can be easily replicated with effectively solving problems of the prior art, especially mechanical lock key, mutual opening rate high, remote control lock signal
Easily it is intercepted, Fingerprint Lock is expensive, temperature is not low easy to identify, and the security and stability of existing electronic password lock is poor
Problem.
