Specific embodiment
To make the objects, technical solutions and advantages of the present invention clearer, clear and definite, develop simultaneously embodiment pair referring to the drawings
The present invention is further described.
As Figure 1-5, the invention discloses a kind of laser reflection tripper, it is included for detecting whether there is key
Groove type photoelectric switch 1, for launching the generating laser 2 being concerned about, laser pickoff 3, controller 4, electromagnetic lock 5 and being used for
The reflection key 6 of unlocking；The groove type photoelectric switch 1, generating laser 2, laser pickoff 3 and electromagnetic lock 5 respectively with control
Device 4 is connected, and the groove type photoelectric switch 1, generating laser 2 and laser pickoff 3 are separately mounted to the key for containing key
Spoon groove 7, the key 6 can be placed in key slot 7 and be unlocked, and laser is launched to reflecting in key 6 by generating laser 2, pass through
Cross reflection after received to laser pickoff 3, finally revolution judges to controller 4 again, it is eligible after, then unlock, do not meet then
Do not unlock.
After said structure, the present invention can detect whether car key groove have key by groove type photoelectric switch, when having
When key, then the pulse code of controller control setting, is converted into Laser emission and goes out by generating laser, Ran Houjing
Reflection key is crossed, if receiving laser and matching for setting by the photo resistance of laser pickoff after reflection, is then controlled
Device can be opened electromagnetic lock with control relay；So this principle using light line reflection is unlocked and current unblock
Mode is entirely different, and this unlocking manner not only requires that laser will meet all reflection channels during reflection, while by
In the pulse code of transmitting be it is multigroup, so being identical also to meet the laser that senses with the laser of setting；Both
It is indispensable, so the process in unblock is tighter, while also more facilitate, without starting, it is only necessary to which reflection key is put
Put key slot.Additionally, also will not there is a problem of unblock because of extraneous light using laser reflection, because laser and one
As day ordinary ray requirement be entirely different.
Furtherly, the groove type photoelectric switch 1 installs the side of key slot 7, and groove type photoelectric switch 1 is typically mounted at lock
Side, and be provided with notch（It is not drawn into）.
Furtherly, the generating laser 2 includes 2 or multiple laser heads 21 for launching laser, and this swashs
Shaven head 21 is connected with controller；The laser pickoff 3 includes the photo resistance 31 of 2 or multiple correspondence sensing laser,
The feedback of the information that the photo resistance 31 will be sensed is to controller；Can be by Laser emission to each of reflection key by laser head
Individual laser entrance, and then internal reflection is realized, and whether photo resistance can then sense reflection outlet and have laser to be reflected,
And then realize the true and false of detection key.
As shown in Figure 2-5, the side of key slot is provided with groove type photoelectric switch in key slot, in the key slot
Surrounding is provided with 8 laser heads, respectively L1-L8;8 photo resistance Q1-Q8 are also equipped with simultaneously, respectively by reflection channel
The respective laser head of correspondence, laser head and the corresponding order of photo resistance are：L1 ~ Q2, L2 ~ Q6, L3 ~ Q3, L4 ~ Q1, L5 ~ Q4,
L6 ~ Q7, L7 ~ Q8, L8 ~ Q5；The reflection key 6 includes setting several laser entrances in key plate body 60, plate body（Do not draw
Go out）, several reflection outlet（It is not drawn into）, some reflection channels 61 and several reflection one side or two-sided reflecting optics
62, the laser entrance and laser exit are arranged on the surrounding of key plate body, and institute's reflecting optics 62 are according to laser entrance and reflection
Outlet is arranged in reflection channel 61.
As shown in Figure 2-5, described transmitting key is double-layer structure, as shown in fig. 6, one layer of the structure of reflection key.
Further, it is also possible to select 6 laser heads and 6 photo resistance, photo resistance is respectively B1-B6, laser head difference
It is A1-A6；Laser head and the corresponding order of photo resistance are：A1 ~ B4, A2 ~ B2, A3 ~ B1, A4 ~ B3, A5 ~ B6, A6 ~ B5.
After using said structure, laser head and photo resistance from different quantity are then different anti-according to setting
The key plate body of passage and the different numbers of plies is penetrated, so that the wide variety of key, equally also causes that key is difficult to replicate,
In the case of there is no key, it is difficult to opened the door by nonviolent means, so antitheft performance is stronger.
Furtherly, the controller 4 is 51 single-chip microcomputers, and 51 monolithics are connected by relay 8 with electromagnetic lock.
As shown in fig. 7, the invention discloses a kind of unlocking method of laser reflection tripper, wherein, including following step
Suddenly：
Step one, puts reflection key into key slot, then detected by groove type photoelectric switch, if having key；
Step 2, when groove type photoelectric switch has detected obstruction, then has key, feeds back to controller, if without obstruction,
Then without key, then groove type photoelectric switch continues to detect；
Step 3, multigroup pulse code for editting of controller control is transferred to generating laser, by being transformed into laser, then by
Laser head is launched；
Step 4, by reflection key again reflexing to photo resistance, photo resistance will simultaneously be sensed for the laser launched
Pipe light-inductive result feeds back to controller；
Step 5, controller judges whether the light-inductive result for receiving meets unlocking condition, if last satisfaction is then controlled
Relay opens electromagnetic lock, if can not meet, then carries out early warning by precaution device.
Furtherly, each photo resistance senses different light paths in the step 4, and arteries and veins is sensed every time
Punching coding is all different.
Furtherly, the respective laser head of the light path correspondence and photo resistance.
Furtherly, the light-inductive result includes each group laser code and light path.
The present invention has detected whether key by groove type photoelectric switch, then launches pulse code by controller again, after turning
Into laser, go whether detection reflection key meets the reflection channel of setting, and the result that laser pickoff will be received by laser
Result with setting is contrasted, if meeting, can be unlocked, and this principle by light line reflection verifies unlocking, institute
To be difficult to replicate；Simultaneously because the analysis to light path just can be reached from 51 singlechip chips, also because reflecting swashing for key
Light entrance, reflection outlet and reflection channel, are complete if this internal structure does not know the entrance and exit corresponding to light path
Cannot replicate.Therefore, it is safer, it is difficult to which that destroyed and theft, outward appearance can be more good-looking.
It should be appreciated that application of the invention is not limited to above-mentioned citing, and for those of ordinary skills, can
To be improved according to the above description or converted, all these modifications and variations should all belong to the guarantor of appended claims of the present invention
Shield scope.
