Now to the operational control of mobile phone.
On the basis of being fully understood by the structure of lens combination of the present utility model, below to the work of the lens combination
Principle is introduced.
Chip is according to current distance and the distance change amount of original distance, and user's eyes number of degrees, and reference is left
The Focussing amount of left and right film is calculated in the number of degrees on right cover plate；According to the Focussing amount and Curvature varying of left and right film
Between relation calculate left and right Curvature varying value；A left side is calculated according to the relation between Curvature varying and first fluid knots modification
The first fluid knots modification of lens devices 1 and right lens device 2, maximum and motor ginseng further according to first fluid knots modification
Number calculates motor stepping-in amount, and motor control data is generated according to motor stepping-in amount；Further according to the He of left lens device 1 being calculated
The difference of the first fluid knots modification of right lens device 2, generate left gas-liquid control valve control data or the control of right gas-liquid control valve
Data.
Specifically, when the eyes number of degrees difference of user, when focusing, the curvature of left film 12 and right film 22
It is different, this just needs to control the left He of first internal cavity 1112 respectively by left gas-liquid control valve 18 and right gas-liquid control valve 28
The amount of flowing in or out of first fluid in right first internal cavity 2112 is different.In order to control simplicity, with the big side of the number of degrees,
On the basis of the influx or discharge for the first fluid being exactly calculated are big, motor control data is generated, and according to meter
It is first-class in the influx of first fluid or discharge and right first internal cavity 2112 in obtained the first internal cavity of a left side 1112
The influx or discharge difference (ratio) of body calculate left gas-liquid control valve control data or right gas-liquid control valve control data.
For example, the target control number of degrees of left side eyes are 500 degree, the target control number of degrees of right side eyes are 400 degree, because
This is defined by left side eyes, and left side gas-liquid control valve does not need work, left side catheter works completely, and since it is desired that right side
Liquid inlet volume (flow) is 80% (400/500) in left side, so needing to control right side gas-liquid control valve control right side catheter
Sectional area accumulates less than left side tube section, so as to realize the liquid inlet volume (flow) on right side for the 80% of left side.
Left gas-liquid control valve 18 changes the caliber of left catheter 15 under the control of left gas-liquid control valve control data, or
Right gas-liquid control valve 28 changes the caliber of right catheter 25 under the control of right gas-liquid control valve control data, only need to control one
The caliber of individual catheter, can be to realize the difference of first fluid inflow or discharge in the first internal cavity of left and right, so as to simultaneously
Realize the regulation of right lenses device focal length.
In the caliber of left catheter 15 or the caliber of right catheter 25 according to left gas-liquid control valve control data or right gas-liquid
After the regulation of control valve control data, motor controls left piston push rod 142 and right piston simultaneously according to Motor Control data
The step motion of push rod 242.
When the eyes number of degrees of user are identical, when focusing, the curvature of left film 12 and right film 22 is identical
, therefore left first internal cavity 1112 is identical with the amount of flowing in or out of the first fluid in right first internal cavity 2112, at this moment
Chip only generates Motor Control data, does not generate gas-liquid control valve control data.
