Embodiment
See also Fig. 1, Fig. 1 is the process flow diagram of a preferred embodiment that the present invention is based on the method for mobile phone for measuring angle.As shown in Figure 1, the disclosed method based on the mobile phone for measuring angle may further comprise the steps:
Step 101: the angular data to be measured of obtaining object under test; Promptly receive respectively the object under test push the handset touch panel surface angular vertex to be measured, with treat on the adjacent one side of angle measurement first and with treating angle measurement the screen touch signal of position separately of second on the adjacent another side, to obtain the angular data to be measured of apex coordinate, first point coordinate and second point coordinate.
Step 102: the angle that obtains to treat angle measurement according to apex coordinate, first point coordinate and second point coordinate.
In step 101, touch-screen is a resistive touch screen.Wherein resistive touch screen is a kind of sensor; (X, physical location Y) convert the voltage of representing X coordinate and Y coordinate into, and resistive touch screen can produce the screen deflection voltage with four lines, five lines, seven lines or eight lines with press points in the rectangular area for it; Read press points (X, voltage Y) simultaneously.Resistive touch screen comprises film and glass; On the film surface adjacent, scribble ITO (Indium Tin Oxides, nano indium tin metal oxide) coating respectively, when touching resistive touch screen with glass; The ITO of film lower floor can touch the ITO on glass upper strata; Spread out of corresponding electric signal via inductor, deliver to CPU (Central Processing Unit through ADC unit (Analog-to-Digital Converter, D/A conversion unit); CPU), X, the Y value to obtain the touch point.
In the present embodiment, touch-screen is a four-wire resistance type touch screen, and it comprises resistive layer of X and the resistive layer of Y, and is as shown in Figure 2.Wherein, the resistive layer of X respectively has a horizontal bus to be used to load bias voltage in the left and right edges of touch-screen, and is as shown in Figure 3.The resistive layer of Y lower limb on touch-screen respectively has a vertical busses to be used to load bias voltage, and be as shown in Figure 4.
When pushing touch-screen, (X is Y) at the coordinate X of the resistive layer of X and at the coordinate Y of the resistive layer of Y to obtain press points respectively through loading bias voltage.Particularly, when measuring coordinate X, the logically equivalent circuit of touch-screen is as shown in Figure 5; Wherein, Rtouch representes the resistance of the resistive layer of resistive layer of X and Y contact point, holds loading bias voltage U at the X+ end with X-; Partial pressure value through detection Y+ place, ADC unit can obtain:
