Beneficial effect of the present invention is: start after this laser transmitter module, this first detecting unit can be detected, in the time that the first light beam being reflected back reaches this first default luminous flux, represent that there is veil in this front that meets thing portion, this veil may be user or other people eyes, so this laser transmitter module can be prohibited to send laser, and then reaches protection effect of avoiding laser to shine directly into eyes.
Accompanying drawing explanation
Fig. 1 is a cut-away view, illustrates that the present invention has the preferred embodiment of the laser system of function of safety protection;
Fig. 2 is a calcspar, and the structure composed of above-mentioned preferred embodiment is described;
Fig. 3 mono-flow chart, illustrates the operation workflow of above-mentioned preferred embodiment.
Embodiment
About aforementioned and other technology contents, feature and effect of the present invention, in the detailed description of the following preferred embodiment that coordinates accompanying drawing, can clearly present.
As shown in Figure 1, 2, 3, the preferred embodiment that the present invention has the laser system 200 of function of safety protection comprises body 20, the first detecting unit 30, and the second detecting unit 40.
This body 20 comprises for the thing portion 21 that connects of corresponding object, for the order portion 22 that connects, laser transmitter module 23, laser receiver module 24, reminding module 25, the operation keys 26 of corresponding user's eyes, and in have the first default luminous flux and second and preset the control module 27 of luminous flux, in the present embodiment, this laser system 200 is that the prestige glasses that possess laser distance measurement function present.
This laser transmitter module 23 is for providing laser to export from the position that this meets thing portion 21.
This laser receiver module 24 is reflected back this and connects the laser of thing portion 21 for receiving, and then provides this control module 27 to do the computing of finding range.
This reminding module 25 is in the time that the first light beam being reflected back reaches this first default luminous flux, to export cue, in the present embodiment, this reminding module 25 adopts flicker cresset, in addition, when actual manufacture, also can show this cue in screen (not shown), or employing buzzer, this cue is voice signal.
This operation keys 26 starts or closes for providing user to operate this laser transmitter module 23.
This first detecting unit 30 is arranged at this body 20, and comprises the first photocell 31, and the first light receiving element 32.
This first photocell 31 is for providing the first light beam from this position output that meets thing portion 21, and this first light beam adopts luminous intensity (Luminous Intensity) to be less than the invisible light of laser.
This first light receiving element 32 is for receiving the first light beam that is reflected back this and connects thing portion 21, and in the time that reaching this first default luminous flux (Luminous Flux), the first light beam being reflected back forbids that this laser transmitter module 23 sends laser, in the present embodiment, setting of this first default luminous flux be with this connect thing portion 21 forward 200cm using interior distance as setting reference.
This second detecting unit 40 is arranged at this body 20, and comprises the second photocell 41, and the second light receiving element 42.
This second photocell 41 is for providing the second light beam from this position output that meets order portion 22, and this second light beam adopts luminous intensity to be less than the invisible light of laser.
This second light receiving element 42 is for receiving the second light beam that is reflected back this and connects order portion 22, and in the time that not reaching this second default luminous flux, the second light beam being reflected back forbids that this laser transmitter module 23 sends laser, in the present embodiment, setting of this second default luminous flux be with this connect thing portion 21 backward 30cm using interior distance as setting reference.
In addition, in the present embodiment, this first photocell 31 is all to adopt infrared diode with this second photocell 41, this first light receiving element 32 is all to adopt photistor with this second light receiving element 42, and this first light receiving element 32 is to convert electric signal to be input to this control module 27 with the luminous flux that this second light receiving element 42 receives.
Below will further illustrate use situation, in the time that this control module 27 detects the triggering signal from this operation keys 26, this second detecting unit 40 can be detected whether crested, if there is no occlusion situations, represent that nobody presses this operation keys 26, this triggering signal is because short circuit or misoperation produce, so this control module 27 can be forbidden this laser transmitter module 23 and be sent laser, and by these reminding module 25 these cues of output, if define occlusion situations, represent that user correctly meets order portion 22 and just operates this operation keys 26 towards this, user's mode of operation is correct, in the time that there is veil at definite this rear that meets order portion 22, then this first detecting unit 30 is detected, if the first light beam being now reflected back is via the judgement of this control module 27, learn while reaching this first default luminous flux, represent that there is veil in this front that meets thing portion 21, this veil may be user or other people eyes, so this control module 27 can be forbidden this laser transmitter module 23 and be sent laser, and by these reminding module 25 these cues of output, in the time that definite this front that meets thing portion 21 does not have veil, so this control module 27 starts this laser transmitter module 23, and then reach protection effect of avoiding laser to shine directly into eyes.
It is worth mentioning that, the present embodiment is to give an example with telescope, when actual manufacture, can also be applied to general sight and mean level instrument, because mean level instrument does not need measuring distance, so can omit this and connect the structure of order portion 22, this laser receiver module 24, this second detecting unit 40, and judge that this connects the whether program of crested of order portion 22, in addition, for judging whether folded light beam reaches the control module 27 of this first default luminous flux, also can adopt analog circuit and combinational logic circuit to realize, when actual manufacture, can not need to use the microprocessor of energy stored routine and data, so can reach the effect reducing costs with hardware space.
The foregoing is only preferred embodiment of the present invention, can not limit scope of the invention process with this, i.e. all simple equivalences of doing according to the claims in the present invention and description change and modify, and all still remain within the scope of the patent.
