Description
【Technical field】
The present invention is about a kind of touch-control transport electronic device, close range wireless communication system and close range wireless communication side
Method；Especially in regard to a kind of electronic device, close range wireless communication system and the low coverage of the safety that can effectively promote communication link
From wireless communication method.
【Background technology】
Near-field communication (Near Field Communication, NFC) is a kind of wireless identification and interconnection technique, is passed through
The method (for example, by using the near field magnetic field communications mode of 13.56MHz) of near field magnetic field communications is produced in mobile device, consumer electronics
Close range wireless communication is carried out between product, PC or intelligent electronic device, exchanges information with allowing user's simple, intuitive, in access
Hold and services.
Since the market demand that the hand-held devices such as mobile phone integrate NFC is ripe, mobile payment or conduct can be supported
Point of sale intelligence channel (point of sale, abbreviation POS) is used, however since NFC is to carry out letter in a manner of magnetic field communications
Number send and receive, it is therefore necessary to the component of induction type card reader or similar functions is added on the hand-held devices such as mobile phone, will
The volume of handheld device is caused to become larger, and restricted with material to the topology layout of the handheld devices such as mobile phone, component.
With the development of touch-control (touch sense) technology, touch control panel device (touch panel device) also day
Gradually popularize.In the application of touch technology, touch control panel device can detect user to its touching and do corresponding reaction；Relatively
In touch technology, a kind of touch-control transmission (touch link) technology, such as US 2011/0304583, US have been developed recently
2013/0147760, it described in the patent application cases such as CN 102916729A, is carried out using the existing hardware of touch control panel device
The wireless transmission of short distance.In general, touch control panel device may include touch panel (touch panel), signal processing electricity
Road (signal processing circuit) and processor (CPU).For example, touch panel can be not have display function
Trackpad (touch pad) or Touch Screen with a display func (touch screen).Touch panel includes touching to feel
Survey device (touch sensor).Touch sensor includes the multiple driving electrodes being disposed on the substrate and induction electrode.Touch surface
What plate was often realized with materials such as indium tin oxides (ITO).Relatively, signal processing circuit is then often realized in a manner of integrated circuit
, major function has two：First, analog-to-digital conversion (ADC), solution are carried out to the analog signal received from touch panel
After adjusting processing such as (demodulation), it is sent to processor.Second, the digital signal that will be received from processor carries out modulation
(modulation) and after number turns the processing such as analog-converted (DAC), it is sent to touch panel.In the application of touch technology,
When user touches touch panel with finger or stylus, by the driving electrodes and induction electrode of touch sensor, will produce
Corresponding analog signal, the signal are sent to processor after signal processing circuit processing, and processor is drilled by appropriate
Algorithm can calculate the position that user touches, and make corresponding reaction according to this.But in the application of touch-control transmission technology, driving
At least one of electrode and induction electrode are as carry electrode to transmit at least another of signal or driving electrodes and induction electrode
Person is as receiving electrode to receive signal.When transferring a signal, a touch control panel device can be by the signal to be transmitted in signal
After processing circuit carries out the processing such as modulation, the side of field coupling (electricfield coupling) is passed through by carry electrode
Formula is sent to another touch control panel device, and receives the signal transmitted by the receiving electrode of another touch control panel device.When
When receiving signal, a touch control panel device can receive a signal by field coupling by receiving electrode, then by signal processing electricity
Road carries out the processing such as demodulating, and is resent to processor and does subsequent arithmetic.Such signal can pass through existing touch panel and signal
Processing circuit is sent and received, and to realize the wireless transmission based on electric field, no longer needs to that induction type card reader is separately arranged
Or the module of similar functions, more previous near-field communication technology more save volume and cost.Certainly, a touch-control can not also be utilized
The existing hardware of panel device, and using another set of touch panel and signal processing circuit to carry out touch-control transmission.In addition, touching
In the application of control technology, common touch control panel device has condenser type (capacitive touch) and resistance-type (resistive
Touch) two types；For the application of touch-control transmission, other than capacitive touch control panel device, touching for resistance-type is used
Control panel device can also implement touch-control transmission technology.
On the other hand, the application of such as WiFi-Direct or Bluetooth communication links is established between two electronic devices
Also gradually universal.For an electronic device, common mode is first to search neighbouring another device, then build by intercoursing
The information of vertical communication link, finally sets up communication link and completes pairing (pairing).However, intensive in electronic device
Place, it is inevasible during search to find many unrelated devices, the puzzlement in connection is caused, and generate safety
Doubt.Under the technology of NFC, though can limit two devices must can complete WiFi- in the short distance within such as 20 centimeters
Direct or Bluetooth pairing.However, for certain situations, 20 centimeters of communication context is still excessive.When user is not turned off
When NFC matching functions, as long as intentionally personage is close at one's side, it is more likely that invade electronic device under user is ignorant and steal
Data.
In view of this, in order to further enhance the safety of communication link, electronic device and the communication of a kind of improvement are needed
Method except making two electronic devices be not necessary to establish the information of communication link using NFC technique is i.e. commutative, and is adjusted by communication
Effective distance safety is substantially improved.
