Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
See also Fig. 2, the structural representation of the two redundant infrared touch panel 9 that it provides for preferred embodiments of the present invention.Two redundant infrared touch panels 9 are provided with:
First group of ballistic device 1, second group of ballistic device 7, it all is arranged in strip, and is installed in respectively on the adjacent both sides of the redundant infrared touch panel 9 of this pair;
The 3rd group of ballistic device 5, the 4th group of ballistic device 3, it all is arranged in strip, and is installed in respectively the first winding receipts device 6, the second winding receipts device 4 near on the sides at the redundant infrared touch panel of this pair 9 centers;
Some ballistic devices of first group of ballistic device 1, the second group of ballistic device 7 respectively some receipts devices with the first winding receipts device 6, the second winding receipts device 4 are relative one by one, and some ballistic devices of the 3rd group of ballistic device 5, the 4th group of ballistic device 3 respectively some receipts devices with the 3rd winding receipts device 2, the 4th winding receipts device 8 are relative one by one.Spacing between adjacent two ballistic devices is the width of a receiver, and each receiver is between two extended lines of adjacent two ballistic devices.
The control circuit of two redundant infrared touch panels as shown in Figure 3, this control circuit comprises microprocessor 12, the first countdown circuit 13 with 1 electric connection of first group of ballistic device, the second countdown circuit 14 with 7 electric connections of second group of ballistic device, the 3rd countdown circuit 15 with 5 electric connections of the 3rd group of ballistic device, the 4th countdown circuit 16 with 3 electric connections of the 4th group of ballistic device, receive the first reception control circuit 17 that device 6 is electrically connected with the first winding, receive the second reception control circuit 18 that device 4 is electrically connected with the second winding, receive the 3rd reception control circuit 19 that device 2 is electrically connected with the 3rd winding, receive the 4th reception control circuit 20 that device 8 is electrically connected with the 4th winding.This microprocessor 12 and four groups of group countdown circuits, four windings are received control circuit and all are electrically connected, four groups of group ballistic devices, four windings receipts device can be controlled respectively, the infrared touch system of any cover can be controlled flexibly like this, and, all right parallel scan adds fast scan speed.
As shown in Figure 4, on the receiving tube both sides ballistic device is arranged, be equivalent to out fenestella, oblique fire sunlight greater than special angle is all sheltered from, make it to shine receiving tube, improve anti-high light performance, namely fenestella can stop the sunlight that is slanted through about part, shine on the receiving device, improved anti-smooth interference performance.Simultaneously since receiving device install relatively lean on after, the sunlight that can avoid on the structure part to slant from above, also can improve the ability of anti-intense laser interfere, that is to say the position that receiving tube is put behind, the sunlight that can reduce to be slanted through above, comparison diagram 5 and Fig. 6 can be clearly seen that, Fig. 5 receiving tube can receive more light, and the light that Fig. 6 receives is then fewer, has really improved anti-intense laser interfere performance.
Because the light transmition direction is straight line, so in infrared touch panel, light shines relative both sides simultaneously at synchronization situation can not occur.As shown in Figure 7, the sun can not synchronization emits beam 10 and 11 liang of opposite light of group of light simultaneously.Based on this, by judging receiving RST just can judge whether strong illumination is arranged, if there is strong illumination just can switch to an other cover, as shown in Figure 2, be subject to intense laser interfere in one party, just can not re-use affected device in this direction, and the device of use opposite face, if the control circuit of a certain cover damages in addition, equally also can switch to another set of working on, do not affect normal use.
The judgement treatment scheme of the control method of two redundant infrared touch panels is as follows:
All devices of the two redundant infrared touch panels 9 of scanning, whether these all devices comprise all ballistic devices and all receiving devices, check all working properly;
If there have to be undesired, the device that record damages, the device of inquiring about this damage belongs to where overlap infrared touch system, chooses a cover in the unspoiled infrared touch system of residue;
If all normal, in the quadruplet infrared touch system, choose a cover;
This that select overlapped infrared touch system start operation.
In addition, can also increase inspection and whether have intense laser interfere:
All devices of the two redundant infrared touch panels 9 of scanning, whether these all devices comprise all ballistic devices and all receiving devices, check all working properly;
If there have to be undesired, the device that record damages, the device of inquiring about this damage belongs to where overlap infrared touch system, the unspoiled infrared touch system of record residue;
Check whether there is intense laser interfere;
If there is intense laser interfere, record receive intense laser interfere that overlap infrared touch system, choose a cover in the unspoiled infrared touch system not receiving intense laser interfere and remain;
This that select overlapped infrared touch system start operation.
In sum, two bank lights are installed on every limit around two redundant infrared touch panels of the present invention, one row is emission lamp, one row is receiving light, and receiving light is placed on the emission lamp back, and per like this two relative edges can form the infrared touch-screen of two covers, when receiving high light or damage on one side, switch to the infrared touch-screen of a cover of the composition of another side, can solve simultaneously when reaching a cover touch screen from being damaged under the high light and can not normally use two difficult problems, really greatly improved the reliability of infrared touch panel.
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
