Description
Technical field
The present invention relates to electronic lock field, more particularly to a kind of light-controlled electronic lock field.
Background technology
Door lock is the very high safety device of today's society frequency of use, in order to improve the anti-difficulty cracked, existing door lock
Enter electronic control mode from the unblock of simple key mechanical.The species of electronic lock is very more, at this stage mainly radio frequency
Card, the vision technique such as fingerprint recognition and retina identification.
But still think that only this material object of key just compares with the presence of user and feel at ease, but the radio frequency that similar card is the same
Card is unsightly, also not readily portable without individual character.Fingerprint recognition has fingerprint sleeve to crack fingerprint recognition, retina identification
It is too expensive.Therefore prior art lacks a kind of embodying user personality, the key of hypostazation, and the uniqueness being engaged with this
, cheap unlocking manner.
The content of the invention
For the present invention in order to solve prior art problem, design one kind shows pattern text based on LED, by dot matrix screen
Word is as key, so as to realize that the light-controlled electronic of User Defined cipher key is locked.
The technical scheme is that：A kind of light-controlled electronic lock, including the control module in body and body, motor, are passed
Motivation structure, tapered end, thoughts Optical Receivers on body, what is be engaged with photosensitive receiving module is light emitters, light transmitting
Device includes portable box body, LED dot matrix screens and control unit, the photosensitive sensor on photosensitive receiving module with LED dot matrix screens
The arrangement mode of LED is identical with spacing.
As a kind of preferred：LED on LED dot matrix screens protrudes from base；It is photosensitive on described photosensitive receiving module
Sensor is arranged on dead slot bottom, and described dead slot diameter is that gap coordinates with protrusion height with the diameter of depth and LED.It is real
Existing light emitters and the accurate fit of photosensitive receiving module, the convenience that lifting user uses, and prevent LED with it is photosensitive
Sensor can not correspond, or the situation of light interference occur.
As a kind of preferred：Control module and control unit are all programmed by USB interface.It is user-friendly and repaiies
Change display pattern.
As a kind of preferred：There are display module and control button on body.It is convenient to show electronic lock working condition and use
Family information.
As a kind of preferred：8255 chips that extend through of photosensitive sensor quantity on photosensitive receiving module provide extension
Interface.It can realize that photosensitive receiving module can receive the picture of more elaborate.
In summary, the beneficial effects of the invention are as follows：
1st, LED dot matrix screens can need to show self-defined pattern or word as key according to user, and light is launched
Device is easy to carry, and lights all LEDs and may be used as illumination use, kills two birds with one stone.
2nd, LED dot matrix screens can be corresponded on the photosensitive receiving module on insertion body in structure, and signal acquisition is accurate, due to
Photosensitive sensor can become more by Interface Expanding chip, and so as to realize that pattern is increasingly complex, key is not easy to be cracked.
