Several embodiment of laser remote-controlled signal receiver and application thereof: embodiment 1 is used to control electric light; Embodiment 2 is used for televisor; Embodiment 3 is used for projecting apparatus system; Embodiment 4 is used for curtain.
Execute example 1:
Laser remote-controlled electric light comprises electric light, telepilot, receiver of remote-control sytem.
Be used for the laser remote-controlled signal receiver of laser remote-controlled electric light, it is characterized in that, described telepilot adopts above-mentioned laser remote-controlled signal projector; Described receiver of remote-control sytem adopts above-mentioned laser remote-controlled signal receiver, the signal comparison module that the signal comparison module adopts the intensity to the electric signal different time of single light activated element to compare; The light signal receiving unit of described laser remote-controlled signal receiver comprises a phototriode and astigmatism plate, and astigmatism plate is fan-shaped flat box, is made by translucent plastic.
It is to repeat to take place repeatedly reflection after making light enter the cavity of box that astigmatism plate adopts translucent box, increases the light intensity on the light-sensitive surface.
At extraneous light is not that very strong place can directly replace box as astigmatism plate with metope.Because it is very strong that the environment that people use electric light generally can light, so be that astigmatism plate has feasibility with the metope.As long as light activated element is tiltedly towards metope, other structures are identical with the laser remote-controlled signal receiver that with fan-shaped flat box is astigmatism plate.
For imagery more and the consideration being convenient to understand, be that the laser remote-controlled signal receiver of astigmatism plate is that example describes still below with fan-shaped flat box.
Scattering is mainly carried out to light signal in the upper strata of astigmatism plate, and the lower floor of astigmatism plate carries out diffuse reflection to light signal.
Phototriode is positioned at the head portion of fan-shaped astigmatism plate, and is positioned at the back side of astigmatism plate Stimulated Light irradiation one side.Because light signal is through the light signal that grows on trees in the astigmatism plate after scattering and the diffuse reflection, thus light-sensitive surface towards restricted very much.But, make the arch section of light-sensitive surface towards fan-shaped astigmatism plate in order to make the better receiving optical signals of phototriode.
The plane of illumination of laser is positioned on the astigmatism plate, the light signal strength that phototriode receives when the head portion of fan-shaped astigmatism plate is far away, a little less than the light signal strength that phototriode receives when the head portion of fan-shaped astigmatism plate is nearer, thus the electrical signal intensity that produces also a little less than.
, as control signal electric light is controlled with the situation of change of electrical signal intensity.
Embodiment 2
The telechirics that existing televisor adopts needs the telepilot of the bigger man-to-man button complexity of volume, and a kind of volume that goes for multiple electrical equipment in the sight line is little passes through simple gesture and carry out the telepilot of remote control and can be more suitable for people and use.
As astigmatism plate, is signal receive section with screen of TV set, is telepilot with the laser remote-controlled signal projector of ring shape.Though television screen is smooth glass, glass-faced part is also rough, can produce good scattering to light.
Smooth in fact glass also can be used as astigmatism plate, because there is not absolute smooth glass, they all can produce diffuse reflection or scattering to light.Test shows, with the smooth glass of laser radiation that the common laser pen produces, can see luminous point in any direction, promptly can produce stronger diffuse reflection.
At housing of TV set and the outside position contacting of television screen light activated element is housed, a light activated element respectively is equipped with at television screen top, below, left, right-hand middle part at least.Light-sensitive surface is slightly towards television screen.

Be positioned at the left and right-hand light activated element, receive, produce corresponding electric signal, and pass to signal processing apparatus by the light signal after the television screen scattering.Signal processing apparatus by analyzing the situation of change of difference and difference, can obtain the situation of plane of illumination left and right sides transverse movement on television screen of laser after electric signal is asked difference.
Under the situation of not carrying out very complicated remote control, it is poor only to compare asking of formula to electric signal, and does not carry out concrete simulation quantitative analysis, thereby just the astigmatism plate face is divided into the digitized zone of a plurality of representative different digital amounts.
By analyzing the horizontal and vertical motion conditions of plane of illumination, can obtain the motion conditions of plane of illumination on whole television screen.By analyzing the motion conditions of plane of illumination on television screen, televisor is carried out corresponding control.
As, utilize the signal of the plane of illumination of the laser that moves up and down in the television screen left side as the voicing sound; The plane of illumination of the laser that utilization is moved up and down on the television screen right side is as the signal of transferring platform.In addition can utilize the simple combination of some simple motions that televisor is carried out complicated remote control, the mode that also can utilize action to combine with button is carried out complicated remote control to televisor.

As astigmatism plate, at least two light activated elements are contained on the projector laser remote-controlled signal receiver, towards astigmatism plate with the screen of projecting apparatus system.
The shading projection of protruding than the plane, light-sensitive surface place of two light activated elements is housed between two light activated elements, blocks the difference of the light signal strength that light activated element is received when strengthening plane of illumination and being positioned at screen sides by light a side.With the camera lens is the shading projection, and two light activated elements lay respectively at the left of camera lens and right-hand.
It is identical that principle of work and laser remote-controlled signal receiver are applied to televisor, but only with laser signal on screen horizontal action situation as remote signal information.
Show up for making lantern slide plough under the signal of next screen, to show up to the laser light of left movement with the laser light that moves right to making lantern slide plough under the signal of a last screen.
Laser remote-controlled signal projector has at least two buttons, and one is sent uncontrolled laser signal by the key control laser instrument, only plays indicative function; One is sent the signal that meets the laser signal of controlling that signal processing apparatus sets by the key control laser instrument, as control signal.
Embodiment 4
Laser remote-controlled signal receiver is an astigmatism plate with the curtain body of curtain, and light activated element is positioned at around the curtain.
Light activated element has four, lays respectively at top, below, the left, right-hand of curtain body, is applied to TV as laser remote-controlled signal receiver, and signal processing apparatus is analyzed the motion conditions of light-sensitive surface by signal is asked poor.
Signal processing apparatus connects actuating unit, and actuating unit connects the curtain body.Signal processing apparatus is analyzed the motion conditions of plane of illumination, by the motion of control actuating unit control curtain.
Laser light is shown up and is moved to the right from the left side, and control curtain body moves right continuously; Laser light is shown up and is moved to the left side from the right, and control curtain body is continuously to left movement; Occur the situation that laser light is shown up and moved to the below from the top or move to the top from the below in the motion process, the motion of curtain body stops.
Based on above-mentioned technology contents, obviously can needn't design door, window, fan, air-conditioning, the sound equipment that this laser remote-controlled signal receiver is housed through under the situation of performing creative labour again, certainly the control quite reasonable of this laser remote-controlled signal receiver to be finished, performing creative labour need be paid certainly these devices.

It should be noted that following problem: should be noted that most, the above-mentioned the most basic purpose of laser remote-controlled receiver is in order to increase the photosensitive area of light activated element in the laser remote control system, to the action message collection at the plane of illumination that moves on the astigmatism plate is to be based upon on the photosensitive area that has increased light activated element, and only being that the action message of plane of illumination is analyzed, is not that light signal is simply followed the trail of.
Therefore the laser remote-controlled signal receiver among the present invention existingly can be considered product identical on the structure essential difference is arranged with multiple with it.As be used in infrared induction device on the door, if the people is considered as astigmatism plate, it is identical with the structure of laser remote-controlled signal receiver among the present invention so, but at first it is not to be used to receive laser signal; Moreover its purpose is not in order to increase the photosensitive area of light activated element; Once more the person it be not that the action message of plane of illumination is analyzed, but people's action is analyzed.
The part of the receiving optical signals of Infrared remote controller, has transparent filter glass, light activated element is equipped with in the filter glass back, if filter glass is considered as astigmatism plate, meet the description among the present invention on the structure, but its purposes is not the photosensitive area that enlarges light activated element obviously, so irrelevant with the present invention.
Employed guided missile laser guidance system on the laser-guided bomb, utilization impinges upon laser light on the target object and shows up object is followed the trail of, if object is considered as astigmatism plate, it is identical with the structure of laser remote-controlled signal receiver among the present invention so, but we know that its purpose is not in order to increase the photosensitive area of light activated element, follow the trail of but laser light shown up, it is a kind of laser guidance system, it or not laser remote control system, target can not be the ingredient of guided missile in addition, so also irrelevant with the present invention.
By foregoing as seen, the device that meets the description among the present invention in the reality is too numerous to enumerate, but the purposes of each parts of these devices obviously with the present invention in the purposes of corresponding parts essential difference is arranged.
Because light signal is through after the scattering, intensity reduces greatly, in order to make laser pickoff better susceptibility and anti-interference is arranged, and laser signal preferably adopts the laser signal of vibration;
As can be known wide by foregoing, laser of the present invention is a branch of thinner light, and is irrelevant with other characteristic that whether has laser, so the laser described in the present invention can be the light that a branch of thinner non-laser light source sends.
Beneficial effect: the laser remote-controlled signal receiver described in the present invention is applicable to that light signal receives, and is specially adapted to laser signal and receives; Cost is low, compares than photoelectric cell under a lot of situations and can reduce up to ten thousand times even more cost; Area occupied is little, and certain part that can use controlled substance does not take any additional areas as astigmatism plate.
