Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched
The specific embodiment stated is used only for explaining the present invention, rather than limitation of the invention.It also should be noted that, in order to just
Part related to the present invention rather than entire infrastructure is illustrate only in description, accompanying drawing.
Embodiment one
A kind of flow chart of touch control detecting method based on infrared light that Fig. 2 provides for the embodiment of the present invention one, this enforcement
Example is applicable to display device and realizes remote-operated situation by infrared light, and the method can be by provided in an embodiment of the present invention
Realize remote-operated device by infrared light to execute, this device can be realized by the way of software and/or hardware, this device
Can be integrated in any need to realize in remote-operated terminal unit by infrared light, such as typically Intelligent flat, such as Fig. 2
Shown, the method specifically includes following steps：
S110, receives infrared scan signal by described infrared touch frame.
Wherein, the operation principle of described infrared touch panel is to be covered with infrared tube, infrared tube bag in the surrounding of touch screen
Include infrared receiving tube and infrared transmitting tube, these infrared tubes are in one-to-one position relationship in the surface alignment of touch screen,
Form a light net being become by infrared light cloth, light net constitutes locating system.(can be finger, with the handss of glove when there being object
Or any touching object) or when infrared light enters infrared light net and stops the infrared light emission in somewhere and receive, this point is anyhow
The power receiving the infrared light that infrared tube receives of both direction will change, and equipment passes through to understand connecing of infrared light
The change of receipts situation just can know that where has carried out touching or being irradiated.It should be noted that carrying out in this programme
During description, the transmitting in infrared tube and reception are not distinguished in detail, be referred to as being launched and received by infrared tube, specifically

The intensity of the outer infrared light that pipe is detected can be amplified, namely creates light path effect as shown in Figure 3.As shown in figure 4,
Due to not having the signal strength values that infrared tube during external interference receives close with the signal strength values of transmitting and assuming week
Phase changes, and as shown in first waveform 3, the signal strength values now detecting are considered as normal intensity value；When finger or other screening
It is 0 that light object touches the signal strength values that infrared tube during Intelligent flat receives, shown in the as second waveform 4；When infrared
Light 2 is irradiated to Intelligent flat, and the signal strength values that the infrared tube on Intelligent flat receives are with respect to normal intensity value slightly
Become big, the 3rd waveform 5 presented based on detection cycle, therefore can be confirmed whether to have object to block according to the size of intensity level or
Person has infrared light 2 to irradiate.Described indicating positions is the position of the hot spot being formed when infrared beam 2 is irradiated on Intelligent flat, when
When Intelligent flat has infrared light 2 to irradiate, the signal that infrared tube receives leads to signal to become strong due to the superposition of infrared light, according to not
The change of equidirectional signal intensity, determines the position that infrared light 2 irradiates.The namely position of touch at infrared control end.
The technical scheme of the present embodiment, receives the intensity level of infrared scan signal by confirming infrared touch frame；According to institute
The size stating intensity level confirms indicating positions on described display device for the infrared light launched at infrared control end, described indicating bit
It is set to the position of touch at described infrared control end, screen is not touched by physics based on infrared light and (and does not use special reception
Device) can be carried out the technique effect of touch control detection, achieve touch control detection on the basis of conventional infrared pen.
