According to the scheme in the present embodiment, it is by judging the infrared signal intensity that infrared receiver component received, when this infrared signal intensity that receives is positioned at optimum range, when being aforesaid minimum predetermined value＜=detected value＜=maximum predetermined value, judge that then this a pair of infrared emission receiving element need not debugging or debugged to finish, in the time of outside being positioned at optimum range, if the infrared signal intensity of this reception is during less than minimum predetermined value, then increase the pulse width of the pairing radiating circuit of corresponding infrared emission component, the signal intensity that infrared emission component is launched suitably strengthens, the received infrared signal intensity of infrared receiver component can correspondingly suitably increase, if the infrared signal intensity of this reception is during greater than maximum predetermined value, then reduce the pulse width of the pairing radiating circuit of corresponding infrared emission component, the signal intensity that infrared emission component is launched can suitably reduce, the received infrared signal intensity of infrared receiver component also can responsively suitably reduce, thereby can make the received infrared signal intensity of infrared receiver component be positioned at optimum range, to reach best user mode, realize the purpose of debugging automatically.
After scheme in using present embodiment is adjusted, when touch panel device is in running order, before a pair of infrared emission receiving element is started working, infrared transmission module is according to the setting value of the pulse width of the pairing radiating circuit of this infrared emission component that sets, the pulse width of radiating circuit is set at the pairing pulse width set-point of current infrared emission component, and with this pulse width set-point execution infrared emission scan operation, at this after work is finished to the infrared emission receiving element, again the following in running order pairing pulse width of infrared emission receiving element of a pair of need is adjusted, by that analogy, thereby the signal intensity that each infrared receiver component is received is positioned within the preset range, makes touch panel device be in good working order.
Wherein, because the difference of the degree of aging of each infrared components, make that the degree of aging of pulse width of the signal that each infrared emission component of infrared transmission module is launched is also different, therefore, after described step S305, can also comprise step:
Step S3051: whether the pulse width after judgement increases is greater than predetermined maximum pulse, if enter step S3052, if not, pulse width after then will increasing is made as the new pulse width of the pairing radiating circuit of this infrared emission component, enters step S306;
Step S3052: this has been aging to the infrared emission receiving element for mark, enters step S307.
Wherein, because the received infrared signal intensity of infrared receiver component may just be offset a very little scope of optimum range, therefore, described step S3052 can also replace with: with the new pulse width of described predetermined maximum pulse as this infrared emission component, enter step S306.
Wherein, before the scheme in carrying out present embodiment, can also comprise step: obtain the pulse width W of the pairing radiating circuit of infrared emission component, wherein, a kind of in can be in the following ways of the acquisition of this pulse width W, the mode that is adopted can be different as required:
One: the main control module of infrared touch screen device sends message getparms to the infrared scan module, and the infrared scan module sends to the main control module with the pulse width of the pairing radiating circuit of each infrared emission component of current device;
Its two: the infrared touch screen device is carried out initialization operation to the infrared scan module, with the initial value of this initialization value as the pulse width W of the pairing radiating circuit of each infrared emission component of infrared scan module;
Its three: the infrared scan module is accepted the instruction of main control module and is carried out initialization operation, and initialization value is sent to the main control module as the initial value of the pulse width of the pairing radiating circuit of each infrared emission component.
Embodiment three:
Owing to the reason that causes the received signal intensity of infrared receiver component to be positioned at outside the optimum range is more, cause the infrared signal intensity step-down, the aging of receiving element that are sent under the equal pulse width to cause receiving sensitivity decline and some other external factor such as dust to block or the like as the aging of radiated element, therefore, in the present embodiment, set forth at the scheme of simultaneously the gain multiple of the pulse width of the pairing radiating circuit of infrared emission component and the pairing receiving circuit of infrared receiver component being adjusted.

Step S401: start one time infrared scan, detect the received infrared signal intensity level of infrared receiver component, be called detected value, enter step S402;
Step S402: judge whether described detected value is greater than or equal to minimum predetermined value and is less than or equal to maximum predetermined value, promptly whether satisfy minimum predetermined value＜=detected value＜=maximum predetermined value, if not, enter step S403, if then need not debug or debug the pairing device parameter of infrared emission receiving element and finish to current this, enter step S408, wherein, this minimum predetermined value and maximum predetermined value can have different setting meanss according to concrete application need;
Step S403: whether further judge described detected value greater than maximum predetermined value, if, enter step S404, if not, promptly described detected value then enters step S405 less than minimum predetermined value;
Step S404: the pulse width W that reduces the pairing radiating circuit of infrared emission component;
Step S405: the gain multiple B that increases the pairing receiving circuit of infrared receiver component;
Step S406: the control infrared transmission module is provided with the pulse width W of the pairing radiating circuit of infrared emission component, and return step S401, carry out the debug process of next round, perhaps judge and use newly-installed pulse width whether can make this that infrared emission receiving element is in normal working range;

Step S408: debugging finishes.
According to the scheme in the present embodiment, it is by judging the infrared signal intensity that infrared receiver component received, when this infrared signal intensity that receives is positioned at optimum range, when being aforesaid minimum predetermined value＜=detected value＜=maximum predetermined value, then judge and need not the pairing device parameter of this a pair of infrared emission receiving element debugged or debugged to finish, in the time of outside being positioned at optimum range, if the infrared signal intensity of this reception is during less than minimum predetermined value, then increase the gain multiple B of the pairing receiving circuit of corresponding infrared receiver component, the received infrared signal intensity of infrared receiver component can suitably be increased, if the infrared signal intensity of this reception is during greater than maximum predetermined value, then reduce the pulse width of the pairing radiating circuit of corresponding infrared emission component, the signal intensity that infrared emission component is launched can suitably reduce, and the received infrared signal intensity of infrared receiver component also can responsively suitably reduce, thereby can make the received infrared signal intensity of infrared receiver component be positioned at optimum range, to reach best user mode, realize the purpose of debugging automatically.
In addition, in the present embodiment, owing to be when received signal intensity during greater than the maximum predetermined value of optimum range, it is the adjustment that the pulse width to the pairing radiating circuit of infrared emission component reduces, and when received signal intensity during less than the minimum predetermined value of optimum range, it is the adjustment that the gain multiple to the pairing receiving circuit of infrared receiver component increases, be positioned at a narrower scope with the pulse width that makes radiated element as best one can, the working time of infrared emission component is reduced, thus the mission life that can prolong infrared emission component.
After scheme in using present embodiment is adjusted, when touch panel device is in running order, before a pair of infrared emission receiving element is started working, infrared transmission module is according to the setting value of the pulse width of the pairing radiating circuit of this infrared emission component that sets, the pulse width of radiating circuit is set at the pairing pulse width set-point of current infrared emission component, infrared receiving module is according to the setting value of the gain multiple of the pairing receiving circuit of this infrared receiver component that sets, the gain multiple of receiving circuit is set at the pairing gain multiple of current infrared receiver component setting value, and with this pulse width set-point, gain multiple setting value is carried out the infrared emission scan operation, at this after work is finished to the infrared emission receiving element, again following a pair of need in running order pairing pulse width of infrared emission receiving element and gain multiple are adjusted, by that analogy, thereby the signal intensity that each infrared receiver component is received is positioned within the preset range, makes touch panel device be in good working order.
Yet because the difference of component ageing degree, the pulse width of the pairing radiating circuit of infrared emission component under the current state or the gain multiple of the pairing receiving circuit of infrared receiver component may approach ultimate value, therefore:
After described step S404, also comprise step:
Step S4041: whether judge this pulse width after reducing less than predetermined minimum pulse width, if, then enter step S4042, if not, then directly enter step S406;
Step S4042: described predetermined minimum pulse width is made as the pulse width of the pairing radiating circuit of this infrared emission component, enters step S406.
Thereby by the judgement to the pulse width after reducing, the pulse width after can effectively preventing to reduce makes infrared emission component can be in normal working range less than the minimum zone that infrared emission component can be provided with.

Step S4052: described predetermined maximum gain multiple is made as the gain multiple of the pairing receiving circuit of this infrared receiver component, enters step S407.
Thereby, by the gain multiple after increasing is judged that the gain multiple after can effectively preventing to increase makes infrared receiver component can be in normal duty greater than the maximum magnitude that the pairing receiving circuit of infrared receiver component can be provided with.
Wherein, before the scheme in carrying out present embodiment, can also comprise step: obtain the pulse width W of the pairing radiating circuit of infrared emission component, the gain multiple B of the pairing receiving circuit of infrared receiver component, wherein, a kind of in can be in the following ways of the acquisition of this pulse width W and gain multiple B, the mode that is adopted can be different as required:
One: the main control module of infrared touch screen device sends message getparms to the infrared scan module, the infrared scan module with each infrared emission component of current device the pulse width of corresponding radiating circuit and the gain multiple of the pairing receiving circuit of each infrared receiver component send to the main control module;
Its two: the infrared touch screen device is carried out initialization operation to the infrared scan module, with the initial value of this initialization value as the gain multiple of the pulse width of the pairing radiating circuit of each infrared emission component of infrared scan module and the pairing receiving circuit of each infrared receiver component;
Its three: the infrared scan module is accepted the instruction of main control module and is carried out initialization operation, and initialization value is sent to the main control module as the initial value of the gain multiple of the pulse width of the pairing radiating circuit of each infrared emission component and the pairing receiving circuit of each infrared receiver component.
It should be noted that, in the present embodiment, in described step S404, when detected value during greater than predetermined maximum, be the pulse width W that reduces the pairing radiating circuit of infrared emission component, in described step S405, when detected value during less than predetermined minimum value, it is the gain multiple that increases the pairing receiving circuit of infrared receiver component, this is to consider, make as far as possible infrared emission component exomonental pulse width be in a narrower scope so that the working time of infrared emission component shortens, prolong the mission life of infrared emission component, in fact, in described step S404, when detected value during greater than maximum predetermined value, also can be the gain multiple B that reduces the pairing receiving circuit of infrared receiver component, in described step S405,, also can be the pulse width that increases the pairing radiating circuit of infrared emission component when detected value during less than minimum predetermined value, in this case, follow-up step also can be done corresponding adjustment.
Embodiment four:
As shown in Figure 5, be the schematic flow sheet of embodiment four of the adjustment method of touch panel device of the present invention, in the present embodiment, be with the difference of embodiment three:
Can also comprise step among the described step S4042: reduce the gain multiple B of the pairing receiving circuit of infrared receiver component, enter step S406 and step S407 then simultaneously, so that pulse width W and gain multiple B to be set.
In this case, possibly can't satisfy the requirement that the infrared signal intensity that infrared receiver component is received is in optimum range owing to reduce pulse width to predetermined minimum pulse width, adjust by gain multiple B the pairing receiving circuit of infrared receiver component, but the pulse width that can not only make the pairing radiating circuit of infrared emission component is positioned at the scope of operate as normal, can also adjust to make and satisfy the requirement that signal intensity that infrared receiver component receives is positioned at optimum range.
In described step S4052, can also comprise: increase the pulse width W of the pairing radiating circuit of infrared emission component, and enter step S4053;
