Data input pin, earth terminal.In the embodiment of the present invention, at least two transmission circuits can refer to the circuit for data transfer,
Circuit controller can specifically refer to field effect transistor metal-oxide-semiconductor.
In the embodiment of the present invention, the electronic equipment can also include at least one bus extender (General Purpose
Input Output, abbreviation GPIO), at least one GPIO it is corresponding with least one connecting interface be connected, for for
The grid of metal-oxide-semiconductor at least two transmission circuits provides voltage control signal.
Optionally, in the embodiment of the present invention, the circuit controller can be respectively arranged with least two transmission circuits.
Specifically, when the circuit controller is metal-oxide-semiconductor, the grid of the metal-oxide-semiconductor can be and circuit where at least one GPIO
It is connected, drain electrode can be connected with least two transmission circuits, and source electrode can be the ground connection with including configuration resistance
Circuit is connected, and when connecting interface is in enabled, i.e., at least in the case of two transmission circuit normal works, the source of metal-oxide-semiconductor
First voltage between pole and grid be present, the first voltage can be the operating voltage for stablizing metal-oxide-semiconductor, in order to control
Metal-oxide-semiconductor opens or closes.
In addition, the resistance value of the configuration resistance in source circuit can be adjusted under GPIO voltage signal, with reality
Now to the adjustment of the electric current of metal-oxide-semiconductor.I.e. the configuration resistance can be swept resistance, such as when GPIO sends voltage high signal,
Can be by the way that the resistance value for configuring resistance is tuned up come increasing circuit voltage.
It is shown in Figure 1, it is interface circuit schematic diagram each at least one connecting interface in electronic equipment.Its
In, Q1 and Q2 represent the control circuit for including metal-oxide-semiconductor being arranged in transmission circuit, its grid (G) and circuit phase where GPIO
Even, its drain electrode (D) is connected with interface circuit (i.e. the first transmission circuit and the second transmission circuit), and source electrode (S) is by configuring resistance
(R1, R2) is grounded.
In the embodiment of the present invention, in the state of normal connection, the first voltage that is maintained between grid and source electrode, this
Control of one voltage in GPIO can be changed within the specific limits, and different value ranges can change more than mobile spy
During definite value, drain electrode and source electrode could turn on, and if the first voltage can be 0.7V, and control source electrode in metal-oxide-semiconductor to be turned on drain electrode
Voltage can be 3.3V.
Because metal-oxide-semiconductor is the electric current that is drained by the voltage for being added in input grid come control output end, i.e. metal-oxide-semiconductor is voltage-controlled
Device, it by the characteristic for the voltage control device being added on grid, will not occur as when triode switchs because of base stage electricity
Charge-storage effect caused by stream, therefore in switch application, the switching speed of metal-oxide-semiconductor is faster than triode.
In the embodiment of the present invention, as the first GPIO being connected with the first connecting interface at least one connecting interface
When receiving voltage high information, in the first transmission circuit and the second transmission circuit that are connected with first connecting interface
The drain electrode of metal-oxide-semiconductor and source conduction, first transmission circuit and second transmission circuit are grounded, and the first connecting interface is broken
The connection with GPIO is opened, first connecting interface is in non-enabled state.
Wherein, the voltage high information can be by setting the connecting interface for needing to close in BIOS in electronic equipment
Afterwards, metal-oxide-semiconductor (i.e. Q1 and Q2 in Fig. 1) is opened by GPIO voltage high signal, that is, increases the electricity between grid and source electrode
Pressure, source electrode is turned on drain electrode, make metal-oxide-semiconductor circuit ground, so as to which the usb signal of the first connecting interface be dragged down, be at
Non- enabled state.
For example, the first voltage between grid and source electrode can be 0.7V or so, when needing to disconnect the first connecting interface,
Will by GPIO by voltage high, when such as drawing high to 3.5V more than 3.3V, then now source electrode just and gate turn-on, at metal-oxide-semiconductor
In open mode, at least two transmission circuit ground connection, data can not be transmitted, the first connecting interface is in non-enabled state.
And when needing to recover the first connecting interface linkage function, GPIO drawings can be sent by the chip being connected with GPIO
The control signal of low-voltage, such as by voltage pull-down to be less than 0.7 0.3V, then now, metal-oxide-semiconductor is closed, drain electrode with
Do not turned between source electrode, i.e., at least two transmission circuits disconnect the connection with ground connection, so that electronic equipment can connect by first
Connection interface carries out data transmission.
It is especially sensitive to electrostatic because USB is that one kind supports hot plug and moveable system in practical application, therefore,
In the embodiment of the present invention, electronic equipment can also include：Electrostatic impedor ESD, positioned at the interface circuit and the metal-oxide-semiconductor it
Between, for the conducting voltage of the metal-oxide-semiconductor to be limited in predetermined voltage range.
In practical application, ESD protection device can be arranged at the connector or port of electronic system so that electric current stream
Electrostatic neutralization is carried out through protection element, and is not passed through sensing element, to maintain the low-voltage of sensing element.The predetermined voltage range
It can be the conducting voltage 3.3V that the voltage loaded on metal-oxide-semiconductor is no more than drain electrode and source electrode, such as can be 0.7V-3.3V.So as to,
During GPIO is drawn high or drags down the voltage of metal-oxide-semiconductor, USB interface can be protected by ESD chip.
Refer to Fig. 2, based on same inventive concept, information processing method during the embodiment of the present invention discloses one, applied to
In electronic equipment, this method includes：

Predeterminated voltage is larger than, so that source electrode turns on drain electrode, wherein predeterminated voltage is usually 3.3V, the second voltage after drawing high
Can be the voltage higher than predeterminated voltage, such as 3.5V, 3.7V.
As shown in Figure 1, when the drain electrode (D) in metal-oxide-semiconductor (Q1, Q2) and source electrode (S) turn on, the transmission to connect with drain electrode is electric
Road is grounded, and causes transmission circuit to fail, and so as to disconnect the data transfer of the transmission circuit and electronic equipment internal, realizes independent close
Close the linkage function of the connecting interface.
Optionally, in the embodiment of the present invention, adjusted by the first connecting interface to non-enabled state, can also by with
Lower step recovers the enabled state of the first connecting interface.It is specifically as follows：
