Specific embodiment
To make the object, technical solutions and advantages of the present invention become more apparent, below in conjunction with accompanying drawing pair
Technical solution of the present invention is described in further detail.It should be noted that in the case where not conflicting, this
Feature in the embodiment and embodiment of application can arbitrarily be mutually combined.
Embodiment 1
Present inventor has found that mobile phone is weighed and there is potential user's demand, and handset touch panel curtain itself
It is exactly pressure, touches (inductance change) inductive pick-up device, this causes the weight measurement of touch intelligent mobile phone to become
For may, and will not additionally increase hardware cost, therefore based on above-mentioned thought, the present embodiment provides a kind of
The method of touch screen terminal and its measurement weight, as shown in figure 1, main include following operation：
Step 100, touch screen terminal starts after heavy measuring function, end level is placed, in terminal screen thing
Object under test is placed in body placement region, the resistance or capacitance of screen objects placement region is detected；
Step 200, by the resistance value for detecting voltage swing is converted into, by the capacitance for detecting conversion
Into size of current；
Step 300, according to the voltage or size of current of conversion, calculates the thing in screen objects placement region
Body weight simultaneously shows.
Wherein, it is as follows for the weighing operation principle of resistance-type touch screen terminal：
When the physical location of touch point (X, Y) in finger or other certain rectangular areas of object pressing screen
When, touch screen resistance value can change, and so as to be converted to X-coordinate, the voltage value changes of Y-coordinate are represented.
Touch screen terminal can sampled voltage size calculate weight size indirectly.It is exactly in fact weight (pressure) that touch screen is weighed
It is converted into resistance value, resistance value and is converted into magnitude of voltage, voltage calculates weight of object as detection meanss.
Computing formula is：G=V/k.
G represents weight of object.V represents voltage.It (is not necessarily linear, with touching that k is proportionality coefficient
Screen characteristics are relevant, but screen determines characteristic and determines that, this coefficient is determined that)
It is as follows for the weighing operation principle of capacitive touch screens terminal：
Capacitance-type touch screen technology is, using the capacitive sensing for touching, to be formed with a coupling in touch screen surface
Electric capacity is closed, the change of capacitor's capacity causes curent change.Touch screen terminal is big according to size of current sense weight
It is little.It is exactly in fact that weight conversion is converted into electric current for capacitance, capacitance that touch screen is weighed, and electric current is used as inspection
Survey means.
Computing formula is：G=I/k.
G represents weight of object.I represents electric current.K (is not necessarily linear, with touch screen for proportionality coefficient
Curtain characteristic is relevant, but screen determines characteristic and determines that, this coefficient is determined that).
When measuring, the precision of weight is measured, depend on terminating circuit AD accuracy of detection.Example：With certain
Object within mobile phone limit measured value 4kg, from 12 bit AD sample chips, precision is:4kg/212
(being here 2 12 powers)=1g (4000/4096=1g).
I.e. certainty of measurement is ± 1g (error ± 1g in other words), and this precision meets enough routine use；
Either touch screens, capacitance plate, as long as the high precision of voltage (or electric current) sampling A/D chip, weighs
Precision just can be ensured.
In addition, at present touch screens, capacitance plate can accomplish that operating characteristic is stablized in ambient temperature range, one
As for -10 DEG C of -+50 DEG C of ambient operating temperature characteristics it is constant, and routine use ambient temperature also without departing from
This scope, therefore can ensure that characteristic is constant, it is ensured that the practicality of measurement weight.
It is in order to further ensure that certainty of measurement, it is preferable that can select aided measurement device, i.e., special
Measurement auxiliary stand, as shown in Fig. 2 the support has done school to the pressure, electric capacity and the set-point that shield
Standard, reduces measurement error.Now, the measurement weight of object under test is as shown in Figure 3.If screen characteristics
Itself reaches, can also this support.This programme is comprising band and without the environment of subsidiary support.
In addition, touch screen terminal can be weighed before dispatching from the factory calibrating, it is ensured that weigh in accuracy rating.Tool
Body implementing measure is：Gone to weigh with standard test weight, according to this weight adjustment reference value；
After dispatching from the factory, user can also apply upper prompting according to App, as shown in figure 4, self calibration.
The principle of calibration revises reference value as when dispatching from the factory, exactly.So manufacturer (or user) can use
Same set of App, for the terminal of different qualities.
