[detailed description of the invention]
For being more fully understood that the present invention, below with reference to accompanying drawing and instantiation, invention is described in detail.
In order to solve the problems referred to above, the present invention provides a kind of Portable payment terminal, it only arranges USB and connects
Mouth can realize support to PC and intelligent communications terminal simultaneously.Specifically referring to Fig. 1, the present invention is relatively
The Portable payment terminal 100 of good embodiment includes main control unit 110, usb 1 20, switch control rule list
Unit 130, switch 140, audio frequency send conditioning unit 150, MIC/GND adaptive unit 160 and audio frequency and connect
Receive conditioning unit 170.
Main control unit 110 is the core cell being responsible for Portable payment terminal 100 overall control.Main control unit
110 select the type of communication interface by the state of the VBUS pin of detection usb 1 20.Please tie
Closing refering to Fig. 2, when VBUS pin is high level, main control unit 110 is received and dispatched by standard usb interface
Data；When VBUS pin is low level, main control unit 110 is by voice communication interface standard transceiving data.
Usb 1 20 is the external interface of Portable payment terminal 100.For meeting Portable payment terminal
100 power supply and data communication requirements, usb 1 20 can be mini USB interface or micro USB connects
Mouthful.Diagram embodiment in as a example by Micro USB, the pin of usb 16 be respectively VBUS pin,
D-pin, D+ pin, ID pin and GND pin, Portable payment terminal 100 passes through USB interface
120 data communications, power or charge.
Switch control unit 130 is for identifying USB communication or voice communication and to control to switch 140 switchings correct
The unit of passage.Switch control unit 130 is connected to usb 1 10, by detection VBUS pin shape
State controls the passage switching that switch 140 execution is corresponding.As in figure 2 it is shown, when VBUS pin is high level,
The USB conducting of switch 140；When VBUS pin is low level, the audio frequency conducting of switch 140.
Switch 140 is switching USB interface or the switch of traffic headset communication interface data channel.Switch 140
It is connected to switch control unit 130, in order to switch USB communication channel or voice communication passage, it is ensured that USB
Communication and voice communication each have the communication channel of self under corresponding pattern, and communication will not interfere.
Audio frequency sends conditioning unit 150 and is connected to main control unit 110, for the number sent by main control unit 110
According to being converted into the audio frequency simulation letter that intelligent communications terminal (intelligent communications terminal 300 as shown in Figure 6) receives
Number output.
MIC/GND adaptive unit 160 uses the traffic ear of the intelligent communications terminal of various criterion for compatibility
Machine interface.MIC/GND adaptive unit 160 is in order to automatically to identify employing Unite States Standard or international standard
MIC and GND of business earphone interface.As shown in fig. 3, use Unite States Standard traffic earphone interface from
Earphone starts to be L channel L, R channel R, public terminal GND and microphone MIC respectively foremost.Figure
Shown in Fig. 3 B, the traffic earphone interface adopted international standards start foremost from earphone be respectively L channel L,
R channel R, microphone MIC and public terminal GND.Can the most intuitively from Fig. 3 A and Fig. 3 B
The definition contrast of traffic earphone interface MIC and GND going out to use Unite States Standard and adopt international standards,
For the traffic earphone interface of compatible both standards, MIC/GND adaptive unit 160 is needed automatically to identify
MIC and GND.MIC/GND adaptive unit be embodied as circuit as a example by circuit shown in Fig. 4, but
Principle and the technology that the present invention relates to are suitable on other MIC/GND adaptive circuits in the same old way.Such as institute in Fig. 4
Show, resistance R1=resistance R2, metal-oxide-semiconductor Q1 and the N-channel that metal-oxide-semiconductor Q2 is same model
1. and ear MOSFET, 2. 1. earphone pin be respectively MIC, GND with earphone pin, or earphone pin
2. power traction pin is respectively GND, MIC.When earphone pin be 1. MIC, earphone pin 2. for GND time,
Owing to the voltage above MIC turns on more than the conducting voltage of Q1, Q1, i.e. earphone pin 2. with portable equipment
GND connection；With should earphone pin 1. be GND, when 2. earphone pin is MIC, Q2 turns on.
This circuit realiration Portable payment terminal 100 automatically identify the traffic earphone interface of various criterion MIC and
GND。
Audio frequency receives conditioning unit 170 and is used for receiving intelligent communications terminal (intelligence communication as shown in Figure 6
Terminal 300) analog signal of left or right sound channel, and nursed one's health the numeral that can process for main control unit 110
Signal exports.
Above-mentioned Portable payment terminal 100 is connected real by USB data line or Audio Data Line with miscellaneous equipment
Now pay.
The USB data line that Portable payment terminal 100 is used be USB interface (mini USB interface or
Person's micro USB interface) turn the data wire of USB interface.
The Audio Data Line that Portable payment terminal 100 is used be USB interface (mini USB interface or
Micro USB interface) turn the data wire of 3.5mm traffic headset plug.Incorporated by reference to refering to Fig. 5,3.5mm ear
The R channel R pin of machine transplanting of rice head, the VBUS pin of Micro USB interface and Micro USB interface
GND pin is unsettled, and the L channel L pin of 3.5mm headset plug is connected with the ID pin of Micro USB,
The GND/MIC pin of 3.5mm headset plug is connected with the D+ pin of Micro USB interface, 3.5mm ear
The MIC/GND pin of machine transplanting of rice head is connected with the D-pin of Micro USB interface.
The data wire that Portable payment terminal 100 is used may also be USB interface (mini USB interface or
Micro USB interface) turn USB interface and the two-in-one data wire of 3.5mm traffic headset plug.
In order to more be visually known the present invention, below with reference to the use of the Portable payment terminal of the present invention
Process is described in further details.
Incorporated by reference to refering to Fig. 6, when user needs to use Portable payment terminal 100 on PC 200,
User by USB data line by the usb 1 20 of Portable payment terminal 100 and PC 200
USB interface be connected.Now, switch control unit 130 and main control unit 110 detect VBUS pin
For high level, controlling switch 140 and switch to USB to turn on, main control unit 110 is set up with PC 200
Communication.
When user uses Portable payment terminal 100 on intelligent communications terminal 300, user passes through audio frequency
Data wire is connected with intelligent communications terminal 300, and switch control unit 130 and main control unit 110 detect
VBUS pin is low level, controls switch 140 and switches to audio frequency to turn on, and intelligent communications terminal 300 is by a left side
Sound channel sends audio analog signals, and audio analog signals is transferred to audio frequency through switch 140 and receives conditioning unit
170, audio frequency receives conditioning unit 170 and audio analog signals is converted into the manageable number of main control unit 110
Word signal.When Portable payment terminal 100 needs to 300 data of intelligent communications terminal, portable
The main control unit 110 paying terminal 100 sends the data to audio frequency transmission conditioning unit 150, and audio frequency sends conditioning
Unit 150 converts the data into audio analog signals, through MIC/GND adaptive unit 160, switch 140,
Usb 1 20 and Audio Data Line are transferred to the MIC interface of intelligent communications terminal 300 and complete to receive
Journey.
