The present invention is that wireless charging system is illustrated by taking smart mobile phone 3 as an example, but is not to be limited,
It is applicable for possessing any mobile phone of display picture.Wireless charging transport unit 10 and wireless charging acceptance division 20
Structure is it is merely meant that common general introduction, is not to be limited yet.The present invention is the secondary coil in wireless charging acceptance division
Three cell windings are at least installed on periphery, receive the induced-current from primary winding transmission, detect to receive power strength, root
It is shown in after detecting the position of primary winding according to the reception power strength on picture.
When smart mobile phone 3 is placed on charging panel 2, induced electricity that sensor coil 110 can be transmitted by primary winding 13
Flow receiving voltage.Then examinations receiving intensity process 10, each reception power strength is detected from three sensor coils 110.
Receiving intensity detection process（Step S10）In, if detecting electric power from more than one sensor coil, come into effect basis
The wireless charging ordered state display control of the present invention.That is, smart mobile phone 3 in the state of charging panel 2 away from arranging shape
State display control is not run, and smart mobile phone 3 is placed on charging panel 2 since sensor coil 110 and detects that reception electric power is strong
When spending, arrangement display control is just come into effect, the method that detection receives power strength herein is carried out exemplified by detecting voltage
Explanation.
Receiving intensity, the reception electricity of each sensor coil are also at least detected in the state of three sensor coils 110 of installation
Power then implements align-err less than minimum value set in advance and shows process（Step S60）.That is, in charging panel 2
During interior installation primary winding, smart mobile phone 3 is placed on charging panel 2 and tangled by edge, then can not detect primary winding
Position and show align-err.
When the reception power strength of each sensor coil is more than minimum value set in advance, implement according to three cell windings
With the setting coordinate process of the position instrument setting coordinate of secondary coil（Step S20）.Setting coordinate is setting arrangement shape to be shown
Coordinate on the picture of state, according to the distance between the model, sensor coil of wireless charging system and position or configuration status meeting
There is difference, the relation between secondary coil also can be different.Therefore according to the model of wireless charging system, in advance with default value,
The center position coordinate of three sensor coil center position coordinates and secondary coil is set respectively, and downloads and applies journey
Sequence makes the selection model and sets sensor coil position and the position coordinates of secondary coil of the model type automatically when installing.
Fig. 6 A and Fig. 6 B are to detect explanation figure according to the primary winding position of the present invention, and Fig. 6 A represent centre arrangement shape
State, Fig. 6 B represent the state away from centre.
After the position coordinates for setting three sensor coils, generate and the receiving intensity detection process respectively（Step
S10）The circular function for the radius that the receiving intensity of each sensor coil of middle detection is inversely proportional.The central point according to known to generating mathematical expression
With the circular function of radius.For example, when maximum receiving intensity is 5V, round radius is set as 1cm, receiving intensity justify when being 3V half
Footpath is 3cm, and when receiving intensity is 1V, round radius is 5cm.Thus after setting, generate round radius and be inversely proportional with receiving intensity
Circular function.
Therefore, as shown in Figure 6B, receiving coil A101 circle is minimum, represents between primary winding 13 and sensor coil A101
Closest, receiving coil B102 represents middle, and receiving coil C103 is represented from centre（The centre of three sensor coils）
Farthest state.
Three circular functions are generated according to the receiving intensity detected from three sensor coils 110, then implement primary winding position
Detection process（Step S40）, three circular functions are explained, primary winding position is a little detected as by what three circles met.Now one
The position of secondary coil is detected as position corresponding with sensor coil coordinate.
The display of picture is the central center point using the coordinate of secondary coil as picture, and the circle for presetting diameter is made
Show for receiving area 105, include together in picture using the position of the primary winding of the detection as primary winding mark 104
On.
Fig. 7's（A）With（B）Be according to the present invention wireless charging system ordered state display picture diagrammatic illustration, Fig. 7's
（A）Expression is arranged in the state of centre, Fig. 7's（B）It is to represent the state away from centre.
In the present invention, the setting position of secondary coil 21 is set in the centre of picture, by the circle of diameter set in advance
Show as receiving area 105, include the position of the primary winding of detection as primary winding mark 104 on picture.With
It, it is normal that primary winding mark 104 is shown as ordered state when entering receiving area 105, as shown in Figure 6B, primary winding mark
104 show on the position of receiving area 105, then show ordered state mistake.And it can be circulated a notice of respectively with buzz
Normal and error condition.
Although and do not shown on accompanying drawing, for be easy to confirm centre point, be shown in the level that centre is met
And vertical line, also it is shown as round with dummy line for the primary winding transit area centered on primary winding 104, strengthens arrangement
The intuitive of state and be easy to observe.
According to the present invention, wireless charging ordered state can be shown on smart mobile phone picture, therefore be easily moved position alignment
Ordered state, normal alignment state is made, is easy to be aligned with state and make wireless charging efficiency be arranged in optimum efficiency,
Prevention because align-err cause the charging interval to extend the problem of.
