Embodiment one:
Be illustrated in figure 1 as the process flow diagram of a kind of two-dimensional location method that first embodiment of the invention provides, for convenience of explanation, only show the part relevant with the embodiment of the invention.
In step S101, the sensitization mobile device is set, this sensitization mobile device comprises radical occlusion device and the some photodiodes that is positioned at assigned address that has optical transmission window.
In embodiments of the present invention, the sensitization mobile device is set at first, wherein, the sensitization mobile device comprises radical occlusion device and some photodiodes that is positioned at assigned address.The radical occlusion device difference, then the position of photodiode is different.Thereby quantity and the position of photodiode be set by the developer according to the shape of radical occlusion device.
Because of the difference of radical occlusion device, the sensitization mobile device has multiple.Wherein, more excellent has two kinds, will describe in detail below.
Wherein a kind of sensitization mobile device comprises a radical occlusion device, have one at described radical occlusion device and be used for the triangle optical transmission window that light sees through, preferably, this triangle optical transmission window is the equilateral triangle optical transmission window, and three photodiodes that be used for to receive the light that sees through from the triangle optical transmission window.The triangle optical transmission window at first is set, with this position of three photodiodes is set, light forms a triangular windows projection identical with the triangle optical transmission window in the projecting plane vertical projection after seeing through the triangle optical transmission window, then arrange on three limits that three photodiodes lay respectively at the triangular windows projection, and wherein two opposite side of photodiode are parallel with the limit of triangular windows projection, two opposite side are vertical with the limit of triangular windows projection in addition for photodiode, as shown in Figure 2.
Another kind of sensitization mobile device also comprises a radical occlusion device, is used for the rectangle optical transmission window that light sees through and have one on this radical occlusion device, comprises that also three are positioned at the photodiode that assigned address is used for receiving the light that sees through from the rectangle optical transmission window.The rectangle optical transmission window at first is set, with this position of three photodiodes is set, light forms a rectangular window projection identical with the rectangle optical transmission window in the projecting plane vertical projection after seeing through the rectangle optical transmission window, then arranging in these three photodiodes wherein, two photodiodes lay respectively on two adjacent vertex angles of rectangular window projection, two groups of opposite side of these two photodiodes are parallel to two of rectangular window projection respectively and face the limit, and the length of side of rectangular window projection is greater than the two edge lengths sums (two photodiodes did not have superposed part when namely two photodiodes were positioned on two drift angles of rectangular window projection) of photodiode, this moment, the light-receiving area of these two photodiodes equated, was 0.25 times of its maximum light-receiving area; Another photodiode is positioned on the base relative with the rectangular window projected apex angle at above-mentioned two photodiode places, and one group of opposite side of this photodiode is parallel with the length of side of rectangular window projection, as shown in Figure 3.
In step S202, by calculating respectively that the light-receiving area of each photodiode after the sensitization mobile device moves obtains some photodiodes laterally and light-receiving area variable quantity longitudinally, and the set up some photodiodes linear relationship of light-receiving area variable quantity and sensitization mobile device moving coordinate laterally and longitudinally
In embodiments of the present invention, when mobile sensitization mobile device, directional light is no longer vertically injected the optical transmission window of radical occlusion device (according to the radical occlusion device difference, triangle optical transmission window or rectangle optical transmission window are arranged), the position that makes light see through the window projection that forms on the projecting plane behind the optical transmission window changes, and the sensitization mobile device is exactly the several times (wherein the sensitization mobile device is set in advance according to the sensitization mobile device by the developer at the multiple of the displacement of the displacement on its plane, place and window projection) of the displacement of the window projection that forms in the projecting plane projection after light sees through optical transmission window in the displacement on its plane, place, just can calculate the sensitization mobile device in the displacement on its plane, place as long as calculate the displacement of window projection.Simultaneously, the light-receiving area of some photodiodes that radical occlusion device is included also can change along with the variation of window projection, light-receiving area by calculating each photodiode respectively light-receiving area sum of all photodiodes as can be known can't become, what change only is single photodiode light-receiving area, because the change in displacement of window projection is not easy to direct calculating, thereby need come the displacement of calculation window projection by the variation of diode light-receiving area.Wherein, the variation size of photodiode light-receiving area can compare after operational amplifier zooms into voltage signal by the photodiode light-receiving area being changed the weak current variation that produces.
Because calculative is the two-dimentional moving coordinate of sensitization mobile device, the sensitization mobile device only needs mobile on the plane, place, and the movement at grade of sensitization mobile device can be decomposed into it horizontal movement and vertically move, thereby below will be respectively illustrates respectively from the movement of horizontal and vertical both direction.The sensitization mobile device is exactly the several times (wherein the sensitization mobile device is set in advance according to the sensitization mobile device by the developer at the multiple of the displacement of the displacement on its plane, place and window projection) of the transversal displacement of the window projection that forms in the projecting plane vertical projection after light sees through optical transmission window at the horizontal moving displacement on its plane, place, and the horizontal light-receiving area variable quantity of the transversal displacement of window projection and some photodiodes is linear.In like manner, the sensitization mobile device vertically moves the several times that displacement is exactly the length travel of the window projection that forms in the projecting plane vertical projection after light sees through optical transmission window (wherein the sensitization mobile device is set in advance according to the sensitization mobile device by the developer at the multiple of the displacement of the displacement on its plane, place and window projection) its plane, place, and vertical light-receiving area variable quantity of the length travel of window projection and some photodiodes is linear.Thereby as long as calculate the light-receiving area that the sensitization mobile device moves each photodiode of back respectively, calculate at the sensitization mobile device according to the light-receiving area of each photodiode again and move the some photodiodes in back at light-receiving area variable quantity laterally and longitudinally, just can calculate the sensitization mobile device laterally and location variation (being the horizontal ordinate of radical occlusion device moving coordinate) longitudinally.
It is linear to specify vertical light-receiving area variable quantity of the length travel of the linear and window projection of the horizontal light-receiving area variable quantity of the transversal displacement of why window projection and some photodiodes and some photodiodes according to two kinds of sensitization mobile devices mentioning among the step S101 below, and step S102 is described in detail.
When the optical transmission window on the radical occlusion device of sensitization mobile device is triangle, mobile sensitization mobile device, the incident angle of parallel rays changes, then radical occlusion device also changes (1,2,3 represent three photodiodes respectively) as shown in Figure 4 in the triangular windows projection that the projecting plane projection forms thereupon.Because the movement at grade of sensitization mobile device can be decomposed into it laterally and mobile longitudinally, thereby below will be respectively illustrate respectively from the movement of horizontal and vertical both direction.As shown in Figure 5, after the sensitization mobile device is laterally mobile, only there is the light-receiving area of photodiode 1 and photodiode 2 to change, the light-receiving area of photodiode 1 has reduced, the light-receiving area of photodiode 2 has increased, and in general, all photodiodes are exactly that current (being that the sensitization mobile device moves the back) light-receiving area of photodiode 2 deducts the light-receiving area (S2-S1) of photodiode 1 at horizontal light-receiving area variable quantity, in Fig. 5, AB is the transversal displacement of window projection, as seen from the figure, AB equals light-receiving area recruitment (or the light-receiving area reduction of photodiode 1 of photodiode 2, or (S2-S1)/2) divided by the length of side L of photodiode, multiply by again
Namely
Thereby, the horizontal light-receiving area variable quantity of the transversal displacement of window projection and some photodiodes is linear, the horizontal moving displacement of sensitization mobile device is also linear with the horizontal light-receiving area variable quantity of some photodiodes thus, just can calculate the transversal displacement of window projection according to photodiode at horizontal light-receiving area variable quantity, and then calculate the horizontal moving displacement of sensitization mobile device.Thereby can obtain: dX=(S2-S1) * λ, wherein, dX represents the horizontal ordinate of sensitization mobile device moving coordinate, λ represents the Sensitirity va1ue preset, S1 represents the light-receiving area of photodiode 1, S2 represents the light-receiving area of photodiode 2, and photodiode 1 and photodiode 2 lay respectively on two waists of equilateral triangle on the projecting plane.When radical occlusion device vertically moves, as shown in Figure 6, photodiode 1, the light-receiving area of photodiode 2 and photodiode 3 all changes, the length of side that establish three photodiodes this moment is L, the distance that radical occlusion device moves down is a, this optical transmission window of sentencing on the radical occlusion device is that equilateral triangle calculates, owing to be projected as equilateral triangle, angle O is 30 ° as can be known, a=2b, therefore, the light-receiving area increment of photodiode 3 is a*L(2b*L just), and the light-receiving area reduction of photodiode 1 and photodiode 2 is b*L, and therefore as can be known, the sensitization total area is constant.The vertical light-receiving area variable quantity that calculates photodiode thus is S1+S2-S3.At this moment, the length travel of window projection equals the light-receiving area recruitment of photodiode 3 divided by the length of side L of photodiode.Thereby, vertical light-receiving area variable quantity of the length travel of window projection and some photodiodes is linear, it is also linear with vertical light-receiving area variable quantity of some photodiodes that the sensitization mobile device vertically moves displacement thus, just can calculate the length travel of window projection according to photodiode at light-receiving area variable quantity longitudinally, and then calculate the sensitization mobile device and vertically move displacement.Thereby can obtain: dY=S

When the optical transmission window on the radical occlusion device of sensitization mobile device is rectangle, mobile sensitization mobile device, the incident angle of parallel rays changes, then radical occlusion device also changes (1,2,3 represent three photodiodes respectively) as shown in Figure 7 in the rectangular window projection that the projecting plane projection forms thereupon.Movement with the sensitization mobile device is decomposed into horizontal and mobile longitudinally equally.Thereby, when the sensitization mobile device laterally moves, as shown in Figure 8, only there is the light-receiving area of photodiode 1 and photodiode 2 to change, and the light-receiving area increment of photodiode 2 equals the light-receiving area reduction of photodiode 1, hence one can see that, and the horizontal light-receiving area variable quantity of photodiode is S2-S1.The light-receiving area recruitment (or the light-receiving area reduction of photodiode 1, or (S2-S1)/2) that the transversal displacement of window projection equals photodiode 2 is divided by half of the length of side of photodiode.Thereby, the horizontal light-receiving area variable quantity of the transversal displacement of window projection and some photodiodes is linear, the horizontal moving displacement of sensitization mobile device is also linear with the horizontal light-receiving area variable quantity of some photodiodes thus, just can calculate the transversal displacement of window projection according to photodiode at horizontal light-receiving area variable quantity, and then calculate the horizontal moving displacement of sensitization mobile device.Thereby can obtain: dX=(S2-S1) * λ, wherein, dX represents the horizontal ordinate of sensitization mobile device moving coordinate, λ represents the Sensitirity va1ue preset, S1 represents the light-receiving area of photodiode 1, S2 represents the light-receiving area of photodiode 2, and photodiode 1 and photodiode 2 lay respectively on two drift angles of the rectangle on the projecting plane.When the sensitization mobile device vertically moved, as shown in Figure 9, the light-receiving area of photodiode 1, photodiode 2 and photodiode 3 all changed, the length of side that establish three photodiodes this moment is L, because c+d=L, therefore as can be known, the sensitization total area is constant.The vertical light-receiving area variable quantity that calculates photodiode thus is S1+S2-S3.At this moment, the length travel of window projection equals the light-receiving area recruitment of photodiode 3 divided by the length of side L of photodiode.Thereby, vertical light-receiving area variable quantity of the length travel of window projection and some photodiodes is linear, it is also linear with vertical light-receiving area variable quantity of some photodiodes that the sensitization mobile device vertically moves displacement thus, just can calculate the length travel of window projection according to photodiode at light-receiving area variable quantity longitudinally, and then calculate the sensitization mobile device and vertically move displacement.Thereby can obtain: dY=S
Vertical* λ, wherein, dY represents the ordinate of radical occlusion device moving coordinate, λ represents the Sensitirity va1ue preset, S1 represents the light-receiving area of photodiode 1, S2 represents the light-receiving area of photodiode 2, and photodiode 1 and photodiode 2 lay respectively on two summits of rectangle on the projecting plane, and S3 represents to be positioned at the light-receiving area of the photodiode 3 on the base of rectangle on the projecting plane.
Seen from the above description, can set up following equation and calculate sensitization mobile device moving coordinate:

In embodiments of the present invention, only need simply to construct the sensitization mobile device, just the Changing Pattern of some photodiode light-receiving areas in the sensitization mobile device in the time of can moving according to the sensitization mobile device, the set up some photodiodes linear relationship of light-receiving area variable quantity and sensitization mobile device moving coordinate laterally and longitudinally, and calculate sensitization mobile device moving coordinate thus.Realized a kind of two-dimensional location method comparatively simply and accurately, and with low cost.In addition, because this scheme is simple, its application also is very extensive, can be applicable to the multiple electronic equipment that need realize two-dimensional localization in move on the plane.For example can be applicable in the remote control mouse, this moment then only need be after calculating sensitization mobile device moving coordinate, the abscissa value of sensitization mobile device moving coordinate is added half of screen lateral resolution, just can know the lateral coordinates value of mouse, in like manner the ordinate value of sensitization mobile device moving coordinate is added half of screen longitudinal frame, just can know the along slope coordinate value of mouse.
