Abstract
An input control method for intelligent touch plates includes the following steps: step one: the touch plate sensor senses the moving of the objects on the touch plate and provides the sensing signal; step two: the touch plate integrated circuit receives the sensing signal and transfers the sensing signal into the touch point position signal; step three: the touch plate transfers the touch point position signal to the touch plate driver module; step four: the touch point position signal is compared with the presupposed signal value by the touch plate driver module, which is regarded as a non-normal input signal when lower than the presupposed signal value and as a normal input signal when higher than the presupposed signal; step five: the touch plate driver module transfers the normal input system to the operating system. Thus, the switch key of the touch plate is not needed and also the non-expected input in accident can be effectively prevented.

Description of drawings
Below in conjunction with accompanying drawing,, will make technical scheme of the present invention and other beneficial effects apparent by the specific embodiment of the present invention is described in detail.
In the accompanying drawing,
Fig. 1 is the hardware block diagram of the input control method of realization Intelligentized touch pad of the present invention;
Fig. 2 is the process flow diagram of the input control method of realization Intelligentized touch pad of the present invention.
Embodiment
Consult Fig. 1, main framework of the present invention is a touch pad 10, a touch pad driver module 20 and a computer operating system 30.Touch pad 10 utilizes the situation of movement of touchpad sensor 11 touch sensitive plates 10 surperficial objects and induced signal is provided, touch pad integrated circuit 12 receives induced signal, and convert induced signal to the touch point position signalling, the touch pad driver module compares processing with touch point position signalling and the signal value of presetting, filter the irregular waveform that produces under the improper situation, send normal input signal to operating system, finish corresponding mouse function.
Fig. 2 realizes process flow diagram of the present invention, as shown in Figure 2, the present invention includes following steps:
Step 1: the situation of movement of touchpad sensor 11 touch sensitive plates 10 surperficial objects also provides induced signal;
In the capacitive type touch pad surface attachment a kind of touchpad sensor 11 is arranged, it is the array matrix form of row and column, and when user's finger touched touch pad 10, it can produce capacity effect on the surface of plate.Touch pad 10 obtains the situation of movement of touch pad 10 surperficial objects by capacitive sensing.
Step 2: touch pad integrated circuit 12 receives induced signal, and converts induced signal to the touch point position signalling;
Touchpad sensor 11 is with touch pad integrated circuit 12, following the tracks of the motion track of user's finger, through inner a series of processing, can accurately locate the position (X, Y parameter) of finger all the time, measure simultaneously because finger and the variation (Z parameter) of distance between plates from the capacitance of (pressure size) formation, and finger contact area and other change in information (W parameter), thereby the information of definite finger shift position.
Step 3: touch pad 10 is to touch pad driver module 20 transmission touch point position signallings;
Touch pad 10 per seconds send 40 to 80 packets and inform the situation of movement of touch pad 10 surperficial objects for touch pad driver module 20.
Step 4: touch pad driver module 20 compares processing with touch point position signalling and the signal value of presetting, the touch point position signalling that will be lower than default signal value is as improper input signal, and the touch point position signalling that will be higher than default signal value is as normal input signal;
When finger touches even during near touch pad 10, just produces capacity effect on the surface of plate, the electrostatic field on the plate face is changed, thereby make touch pad 10 produce induction.For fear of the mistake input of some improper situations, must handle accordingly the induced signal of touchpad sensor 11 perception.
The force value of touch pad (Z parameter) is a movement of objects parameter value whether effectively on the decision touch pad 10, if should be worth less than certain level, even finger moves on touch pad 10, the cursor pointer still can be in the state that does not respond, and it is effective only just being considered to this touch-control action when force value surpasses certain level.
Touch pad driver module 20 is set a force value boundary according to different situations, when touch pad driver module 20 does not obtain normal input signal after a period of time, touch pad driver module 20 is set to default force value (Z parameter) boundary greatly, make its any action that does not respond the object on the touch pad 10, realize the closed condition of touch pad 10.Behind a series of well-regulated, continuous, the metastable force value waveform that touch pad driver module 20 receives that touch pad 10 transmits, default force value (Z parameter) boundary is set to normal value, make it recover normal and use, realize opening automatically of touch pad.
Touch pad driver module 20 compares processing with touch point position signalling and the signal value of presetting, the touch point position signalling that will be lower than default signal value is as improper input signal, and the touch point position signalling that will be higher than default signal value is as normal input signal.
Step 5: the touch pad driver module sends normal input signal to operating system.
The touch pad driver module sends normal input signal to operating system, realizes corresponding mouse function by it.
In sum, the input control method of Intelligentized touch pad of the present invention by touchpad sensor 11 touch sensitive plates 10 surperficial objects situation of movement and induced signal is provided, touch pad integrated circuit 12 receives induced signal, and convert thereof into the touch point position signal, comprise horizontal ordinate (X, Y parameter), force value (Z parameter) and finger contact area and other information (W parameter), touch pad driver module 20 compares processing with touch point position signalling and the signal value of presetting, filter the irregular waveform that produces under the improper situation, send normal input signal to operating system, finish corresponding mouse function, effectively preventing the non-expectation input under the fortuitous event.
The above for the person of ordinary skill of the art, can make other various corresponding changes and distortion according to technical scheme of the present invention and technical conceive, and all these changes and distortion all should belong to the scope that the present invention protects.
