Embodiment
To make the purpose of this utility model, technical scheme and advantage clearer, clear and definite, develop simultaneously implementation referring to the drawings
The utility model is further described example.
As Figure 1-5, the utility model discloses a kind of laser reflection tripper, it is included for detecting whether having
The groove type photoelectric switch 1 of key, for launching the generating laser 2 being concerned about, laser pickoff 3, controller 4, the and of electromagnetic lock 5
Reflection key 6 for unlocking；The groove type photoelectric switch 1, generating laser 2, laser pickoff 3 and electromagnetic lock 5 respectively with
Controller 4 is connected, and the groove type photoelectric switch 1, generating laser 2 and laser pickoff 3 are separately mounted to be used for containing key
Key slot 7, the key 6 can be placed in key slot 7 and unlocked, and laser is launched to reflection key 6 by generating laser 2
In, received after reflection to laser pickoff 3, finally revolution judges to controller 4 again, it is eligible after, then unlock, be not inconsistent
Conjunction is not unlocked then.
After said structure, the utility model can detect whether car key groove has key by groove type photoelectric switch,
When having key, then the pulse code of controller control setting, is converted into Laser emission by generating laser and goes out, so
Afterwards by reflecting key, if the photo resistance of laser pickoff receives laser and matching for setting after reflection, then
Controller can be opened electromagnetic lock with control relay；So this principle reflected using light come be unlocked with it is current
Unlocking manner is entirely different, and this unlocking manner not only requires that laser will meet all reflection channels during reflection, together
When due to the pulse code of transmitting be it is multigroup, so being identical also to meet the laser that senses and the laser of setting；
Both are indispensable, so the process in unblock is tighter, while also more facilitating, without starting, it is only necessary to will reflect key
Spoon containing key groove.In addition, also will not be because of extraneous light using laser reflection, the problem of there is unblock, because laser
Requirement with general day ordinary ray is 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 being used to launch 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 photo resistance 31 is by the feedback of the information sensed 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, pass through reflection channel respectively
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 sides 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
For 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 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 key to be 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 utility model discloses a kind of unlocking method of laser reflection tripper, wherein, including with
Lower step：
Step one, put 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 not hindering
Hinder thing, then without key, then groove type photoelectric switch continues to detect；
Step 3, multigroup pulse code that controller control is editted is transferred to generating laser, by being transformed into laser,
Launched again by laser head；
Step 4, the laser launched is reflexing to photo resistance again by reflection key, and photo resistance simultaneously will sensing
To pipe light-inductive result feed back to controller；
Step 5, controller judges whether the light-inductive result received meets unlocking condition, if last meet then
Control 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 utility model has detected whether key by groove type photoelectric switch, then launches pulse code by controller again,
Into laser after turning, detection reflection key is gone whether to meet the reflection channel of setting by laser, and laser pickoff is by reception
As a result the result with setting is contrasted, if meeting, and can be unlocked, this principle reflected by light, to verify out
Lock, so being difficult to replicate；Simultaneously because the analysis to light path just can be reached from 51 singlechip chips, also because reflection key
Laser entrance, reflection outlet and reflection channel, if this internal structure does not know the entrance and exit corresponding to light path, be
It can not replicate completely.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 present utility model is not limited to above-mentioned citing, those of ordinary skill in the art are come
Say, can according to the above description be improved or converted, all these modifications and variations should all belong to the appended power of the utility model
The protection domain that profit is required.
