The controller carries Android system.
The display unit uses touch display screen.
Moneychanging system in internet of the present invention, for real money to be converted into internet electronic money and returned to existing
The holder of real currency, first, the money information that money recognition unit identification people deliver, automatic vending machine can be used here
Coin identification technology, so, controller can be obtained according to money recognition unit people delivery coin numerical information, control
This coin numerical information is sent to wireless module B by device by wireless module A again, and wireless module B passes this coin numerical information
Server is given, after server receives the coin numerical information, sends instruction, is passed by wireless module A and wireless module B
Controller is given, so that controller generates the transfer accounts Quick Response Code corresponding with the coin numerical information, and is shown in display
On unit, the Quick Response Code of transferring accounts is wechat payment code or Alipay payment code, specially the payment code of which platform, Yong Huke
Operation selection on the display unit, so, after people's handset Wechat or Alipay barcode scanning, you can turn the cash currency of delivery
It is changed to electronic money.
The circuit diagram of power module is as shown in Fig. 2 including resistance R1, comparator U1, triode VT2 and triode VT1, institute
State resistance R1 one end and connect power supply VCC and resistance R3 respectively, the resistance R3 other ends connect grounding resistance R2 and comparator U1 respectively
In-phase end, comparator U1 end of oppisite phase connection resistance R4, the resistance R4 other ends connect the resistance R1 other ends, resistance R5 and three poles respectively
Pipe VT1 colelctor electrodes, triode VT1 base stages connect the resistance R5 other ends and triode VT2 colelctor electrodes, triode VT1 transmittings respectively
Pole connects output end vo, triode VT2 emitter stages connection electric capacity C1, and the electric capacity C1 other ends connect resistance R7 and are simultaneously grounded, resistance R7
The other end distinguishes connecting triode VT2 base stages and comparator U1 output ends, comparator U1 power ends connection power vd D.The electricity
Source VCC be the rectified voltage stabilizing of 220V electric mains after obtain；The comparator U1 uses LM339.
Resistance R2, R3 are the bleeder circuits of reference voltage, according to the intrinsic standoff ratio of R2, R3 in figure（51 Europe/10K Europe）；Va ends
Voltage is 11.939V, and the potential difference Uab between R1 ends As and B changes with the change of load current.Born at output end vo
Electric current B point points position respective change therewith when changing is carried, load current is big, and B points current potential declines；Load current reduces, B points electricity
Position rises；When load current is zero, B points current potential is equal to A point current potentials, and the current potential of this change of B points is as sampled signal；By R4
It is added to comparator U1 inverting input.From figure 1 it appears that when load current is zero, A points voltage, B point voltages are
12V.Now comparator U1 anti-phase inputs terminal voltage Vb is 12V, in U1 in-phase input ends, due to U1 homophase input terminal voltages be through
Cross R2, R3 bleeder circuit and meet 12V.According to R2, R3 ratio（51 Europe/10K Europe）U1 in-phase input ends Va voltage is
11.939V, it is clear that Va current potentials are less than Vb current potentials, and U1 output ends are low level, and now, triode VT2 is not triggered conducting, three poles
Pipe VT2 no currents are by the way that VT1 provides positively biased saturation conduction by R5, and 12V voltages export by transistor VT1.When load current very
When big, because the electric current for flowing through sample resistance R1 rises, the pressure drop at R1 both ends also rises, and now A points current potential is constant, B point current potentials
Decline because of R1 pressure drop rise, this voltage declined, the inverting input of comparator is added to by R4, works as load current
Continue to rise, Vb current potentials continue to decline；When Vb descends below Va 11.939 V, Va is more than Vb, exports by low transition
For high level, this high level is added to triode VT2 base stages, triode VT2 conductings, due to VT2 conducting, triode VT1's
The positive bias-voltage of base stage is turned on by VT2, and bypasses and lose biasing into ground, triode VT1, be changed into ending from conducting, output end vo electricity
Pressure is cut off, into guard mode.Electric capacity C1 effect is to utilize its charging current, improves triode VT2 switching speed, enters
And improve the reaction speed of circuit.
The quantitative concrete numerical value for analyzing circuit safety operating current and protective current of the present invention below：
1st, in the case where 12V circuits do not have electric current, Va is 11.939V, and Vb 12V, comparator output terminal is low level output.
2nd, when 12V power supplies are 1A electric currents, Va is 11.939V；Vb is 12V-0.03 × 1=11.97V, comparator output terminal
For low level.
3rd, when 12V power supplies are 2A electric currents, Va is 11.939V；Vb is 12V-0.03 × 2=11.94V, comparator output terminal
For low level.
4th, when 12V power supplies are 2.05A electric currents, Va is 11.939V；Vb is 12V-0.03 × 2.05=11.9385V, is compared
Device output end is high level.
It can be seen that Va is reference voltage；Set for 11.939V by R2, R3 intrinsic standoff ratio.When it is 2A to flow through electric current, on R1
Pressure drop is 0.06V, and Vb voltages are that 12V-0.06V=11.94V is more than Va voltages, and comparator output terminal is low level；When what is flowed through
When electric current is 2.05A（Increase 0.05A）, Vb voltages are 12V-0.0615V=11.9385V, the 11.939V less than Va, comparator
Output end is high level, and trigger protection circuit works；Cut off 12V power supplies（High current supply line, electric current only increase 0.05A guarantors
Protection circuit acts）.
As can be seen here, employ after voltage comparator circuit is used as the detection comparison circuit of protection circuit, it controls essence
Spend at a relatively high, electric current only increases 0.05A protection circuits and acted, and due to being integrated circuit, its reliability, uniformity also obtain
Greatly improve, circuit structure is simple, and cost is low.
In summary, moneychanging system in internet of the present invention can receive real money, then electric accordingly to user
Sub- currency, the life of people is greatly facilitated, there are very big market prospects.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, Er Qie
In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, the scope of the present invention is by appended power
