Description
Technical field
The present invention relates to a kind of anti-theft device, more particularly to a kind of mechanical lock braked without key.
Background technology
It is with a long history as the tradition machinery lock of anti-theft tool, still large-scale use now.But existing mechanical latching is three
Individual deadly defect：Firstth, lock core does not resist strong destruction using materials such as common copper, aluminium, zinc；Secondth, lockset makes work
Skill, it is backward in technique, it is impossible to prevent the unlatching of technological means；3rd, indispensable key, not only carries indecency, and easily stolen use
Replicate.Many locksets both domestic and external, do not possess real anti-theft feature actually in the market.
With the progress of modern age electronics science, electronic lock carries its convenience and portability enters market, but its
There is potential safety hazard without mechanical braking in body and its fancy price has contained its development；Fingerprint Lock is produced safely as the third generation
Product, have broken the function of the single enabling of traditional mechanical lock, are collection optics, machinery, electronics and finger print core algorithm skill
Art is the high-tech product of the whole body.Present Fingerprint Lock has a many functions, such as network savvy, enabling writing function, long-range
Remote control, intelligent alarm, multi-player mode, manager's rank etc..For a user, using Fingerprint Lock be used for opening door lock when
Between it is very short, most of the time is that lock is in static state, then static consumption of attacking is just very crucial, and this is to determine fingerprint
Lock the technical indicator of the most critical of battery, if to attack consumption larger for static state, may a lock be placed on upper 3 months of door without
Once, may be just no electric, furthermore, Fingerprint Lock must be adopted on the basis of using electronic technology to biological characteristic
Collection, compare, differentiate, misclassification rate namely open by mistake lock probability be a ten thousandth, refuse it is sincere namely you store after fingerprint refuse
The probability of unlocking is up to 3/1000ths.
Not the problem of electronic lock, Fingerprint Lock do not only exist misclassification rate, refuse sincere high and expensive, and be all necessarily required to
Electric energy is supported, therefore is not suitable with the door configuration of all natural environments.
The content of the invention
