Necessary power supply.
In a specific embodiment, such as mobile phone and when peripheral hardware interaction, it should realize and charge the phone, while is real
AR glasses outside existing mobile phone connection, it is this cannot frequently plug in the case where, so that it may realize the number of mobile phone and AR glasses
It according to exchange, while being switched fast to provide to eyes and power supply or charge the phone, realize prolonged video capture.Regardless of
It is the communication mode of fast charge mode or mobile phone and peripheral hardware, is all a kind of two-way handshake procedure.Control in control module
Circuit, power-switching circuit, signal switching circuit, charge switch circuit, communication interface circuit and power interface circuit processed are as schemed
Shown in 3- Fig. 9, wherein 3 feet, 7 feet, 10 feet, 14 feet are the common pin of switch in Fig. 3, and network numbering is intended merely to principle reality
Existing convenience only represents the realization principle of function to a name of name identity function.As shown in Fig. 3-Fig. 9, when selection is opened
(3,4 feet are connected in Fig. 3 when pass pushes charge mode；7,8 feet are connected；9,10 feet are connected；13,14 feet are connected), at this moment CC1 foot connects
It is connected to pull-up resistor.After CC1 foot pull-up resistor, mobile phone can automatically switch to Device mode, indicate entry into charge mode, if
Mobile phone and charger baby all support fast charge, then will according to after fast charge protocol handshake enter fast charge mode.OUT_PHONE_ simultaneously
After EN ground connection, metal-oxide-semiconductor (U6 in Fig. 6) would be at operating mode, and at this moment the power supply of 2 foot of U6 pipe passes to 3 feet, and realization is given
Mobile phone charging.At this moment the end SS is also in ground connection mode, SS signal is to the enabled letter of selection switch of U1 chip (U1 in Fig. 5)
Number, after the ground connection of the end SS, the USB line of mobile phone will be connected to the USB line of charger baby, realize the communication of fast charge agreement.Selection is opened
(3,2 feet are connected in Fig. 3 when pass pushes state of a control；7,6 feet are connected；10,11 feet are connected；14,15 feet are connected), selection is opened at this time
It closes and is in state of insulation, system is without any processing, this is equivalent to the buffer area of one safety of system, guarantees electric property
Insulation.
When switch pushes communication state, (3,1 foot is connected in Fig. 3；7,5 feet are connected；10,12 feet are connected；14,16 foot phase
Even), at this moment CC1 foot connects pull down resistor, and after CC1 foot connects pull down resistor, mobile phone terminal will recognize corresponding state, at this time hand
Machine would be at HOST mode, that is, have the function of OTG, external output voltage, be supplied to peripheral hardware (when charger baby power is less than
It, just can be effective when mobile phone output power).USB_INPUT_9V/5V terminal is connected with OUT_5V_GLXSS interface simultaneously, this is with regard to phase
When the voltage and current in charger baby has flowed directly into peripheral hardware, it is supplied to SLAVE equipment.There are also the ports SS to meet USB_SEL_VCC
End, since USB_SEL_VCC is the operating voltage to U1 chip that U2 chip (U2 in Fig. 4) LDO is generated, so the height electricity at the end SS
The flat requirement for meeting U1 chip.After SS terminates high level, according to U1 chip concept, D+/- signal connects DG+/- signal at this time,
To make the end HOST be connected with the end SLAVE, communication function is completed.It is powered simultaneously by charger baby to SLAVE.
Specifically, U2 chip is LDO in Fig. 4, for the voltage (voltage that charger baby provides) of input to be converted into U1 core
The operating voltage of piece can realize that power supply is converted regardless of charger baby provides 5V or 9V voltage.
The power supply USB_SEL_VCC of U1 chip is provided by U2 chip in Fig. 5.U1 chip mainly realizes usb signal
Switching.When SS terminates high level, D+/- signal is connected to D2+/- port, since D2+/- port connection is peripheral hardware, institute
It is got through with the communication channels of mobile phone at this time and peripheral hardware；When SS terminates low level, D+/- signal and D1+/- signal communication, by
What it is in D1+/- signal termination is charger baby port, so corresponding mobile phone usb signal will be connected with the usb signal of charger baby, this
It is to realize to the necessary condition of mobile phone fast charge.
U6 is a switching tube in Fig. 6, realizes the charging to mobile phone, while can also be realized when mobile phone and peripheral hardware communication,
Power supply is provided to peripheral hardware.Concrete principle is that it is idle in mode that the 1 foot default of U6, which is high level,.But after 1 foot is lower,
According to the principle of U6,2 foot voltages flow to 3 feet, this application is mainly that charger baby charges the phone；There are also a kind of scenes, that is just
It is when mobile phone is OTG mode, although 1 foot is that high level can be mentioned when charger electric quantity is low or does not have charger baby at this time
Power supply source is to peripheral hardware.
Communication interface circuit in Fig. 7 needs to connect news main equipment, such as mobile phone, this interface are external by cable mode
Mouth is drawn.Communication interface in Fig. 8 needs to connect news from equipment, such as intelligent glasses, this interface is external by cable mode
Mouth is drawn.Power interface circuit needs external power supply, such as charger baby in Fig. 9, this interface passes through cable mode chain interface.
Charging can be realized by the data line of the utility model and communicates the dual function of (OTG), extending cell phone and peripheral hardware
Working time, OTG line and charging cable are saved in economic benefit.It is more that data line is also eliminated in structure, it is inconvenient to carry
The problem of.Simultaneously in connecting-disconnecting interface is frequently applied, the risk of interface damage can be reduced.Do not plugging mobile phone terminal, charger baby
In the case where end and peripheral hardware end, so that it may the switching that realization quickly charges the phone, mobile phone and peripheral hardware communicate.
The utility model embodiment also provides a kind of data transmission system settable based on OTG function charge and discharge, described
System includes: power supply, the first peripheral hardware, the second peripheral hardware and the data line；The data line is respectively and outside the power supply, first
And if the second peripheral hardware is detachably connected.
