Detailed Description
Referring to the drawings, wherein like reference numbers refer to like elements, the principles of the present invention are illustrated as being implemented in a suitable computing environment. The following description is based on illustrated embodiments of the invention and should not be taken as limiting the invention with regard to other embodiments that are not detailed herein.
It is understood that the execution subject of the embodiment of the present application may be an electronic device such as a smart phone or a tablet computer.
Referring to fig. 1, fig. 1 is a schematic flow chart illustrating an identification method of a device according to an embodiment of the present disclosure. The device identification method can be applied to electronic devices. When the Type-C interface of the external equipment is not detected to be accessed into the Type-C interface of the electronic equipment, the configuration channel pin of the Type-C interface of the electronic equipment has no detection voltage. The flow of the device identification method provided in this embodiment may include the following steps:
in step S101, it is detected whether a preset trigger operation is received, the preset trigger operation being an operation received from a user to indicate that external device identification is required.
At present, USB interfaces used on a plurality of terminal devices are all Type-C interfaces. The highlight of the Type-C interface is the slimmer design, faster transmission speed (up to 10Gbps), and more aggressive power transmission. And, Type-C interface supports and all can insert "positive and negative to insert" function from positive and negative both sides.
Referring to fig. 2, fig. 2 is a pin arrangement diagram of a Type-C female socket interface in the related art. The signal processing method comprises the following steps of TX1+, TX1-, RX1+, RX1-, TX2+, TX2-, RX2+ and RX 2-are four pairs of differential signal pins, D + and D-are differential signal pins compatible with the USB2.0 standard, VBUS is a power supply pin, CC1 and CC2 are configuration channel pins, and SBU1 and SBU2 are bus pins. Through configuring the channel pins, the electronic equipment can perform identification of external equipment, role distinction of master and slave equipment, insertion identification of front and back sides and the like.
In this embodiment, when it is not detected that the Type-C interface of the external device is connected to the Type-C interface of the electronic device, the configuration channel pin of the Type-C interface of the electronic device has no detection voltage. That is to say, in this embodiment, the electronic device does not perform access detection of the Type-C interface of the external device through the configuration channel pin of the Type-C interface, but performs access detection of the Type-C interface of the external device through other manners. Only when detecting that there is the Type-C interface of external equipment to insert electronic equipment's Type-C interface, electronic equipment can provide detection voltage for its Type-C interface to external equipment discerns.
However, in some cases, a problem may occur that the Type-C interface (e.g., Type-C male connector) of the external device has already been connected to the Type-C interface (e.g., Type-C female socket interface) of the electronic device, but the Type-C interface of the electronic device cannot identify the external device.
In step S101 of the embodiment of the present application, for example, the electronic device may first detect whether a preset trigger operation is received from a user. The preset trigger operation is an operation for indicating that the external equipment needs to be identified.
If the preset trigger operation is detected not to be received, the electronic equipment can execute other operations.
If the preset trigger operation is detected to be received, the process proceeds to step S102.
In step S102, if the preset trigger operation is received, a first detection voltage is provided to a configuration channel pin in a Type-C interface of the electronic device.
In step S103, after the first detection voltage is provided to the configuration channel pin, the external device is identified through the configuration channel pin.
For example, steps S102 and S103 may include;
when the external device needs to be identified, the user can send a preset trigger operation to the electronic device. When the electronic device receives a preset trigger operation for indicating that the external device identification is required from a user, the electronic device can provide a first detection voltage for a configuration channel pin in a Type-C interface of the electronic device.
After providing the first detection voltage for the configuration channel pin in the Type-C interface of the electronic device, the electronic device may identify the external device through the configuration channel pin to determine what kind of device the external device is specific. For example, in some embodiments, the external device may be a device such as a headset using a Type-C interface or a USB flash drive using a Type-C interface.
It should be noted that the Type-C interface has three roles, which are a downlink interface, an uplink interface, and a dual role interface. When the Type-C interface of the electronic equipment is used as a downlink interface, the electronic equipment is used as main equipment, can supply power for the accessed external Type-C equipment, sends data to the external Type-C equipment, reads the data from the external Type-C equipment and the like. When the Type-C interface of the electronic equipment is used as an uplink interface, the electronic equipment is used as slave equipment, power can be obtained from the accessed external Type-C equipment, and data and the like are provided for the external Type-C equipment. When the Type-C interface of the electronic equipment is used as a dual role interface, the electronic equipment can be dynamically switched between the master equipment and the slave equipment.
For example, in this embodiment, the Type-C interface of the electronic device may be configured as a downlink interface, that is, the electronic device serves as a master device. When the Type-C interface of the external device is configured as an uplink interface, that is, the external Type-C device is used as a slave device, a configuration channel pin of the Type-C interface of the external device is connected with a pull-down resistor (the pull-down resistor may be a single resistor, or may be formed by connecting a plurality of resistors in series and/or in parallel).
It is easy to understand that, when the Type-C interface of the external device is connected to the Type-C interface of the electronic device, the configuration channel pin of the Type-C interface of the electronic device is connected to the configuration channel pin of the Type-C interface of the external device, so that the configuration channel pin of the electronic device is connected to the pull-down resistor of the configuration channel pin of the external device, and the voltage on the configuration channel pin of the electronic device is pulled down.
And for external devices with different functions (such as earphones and U disks adopting a Type-C interface) the resistance values of the pull-down resistors connected with the configuration channel pins are different. Therefore, when external devices with different functions are connected to the electronic device, the voltage of the configuration channel pin of the electronic device is pulled down to different degrees. Therefore, the electronic device can identify what kind of device the external device is by the voltage variation value of its configuration channel pin.
It can be understood that, in the embodiment of the present application, when it is required to identify an external device that uses a Type-C interface, a user may send a preset trigger operation to an electronic device. When it is detected that the preset trigger operation is received from the user, the electronic device may provide a first detection voltage for a configuration channel pin in a Type-C interface of the electronic device, so as to identify the external device. That is, this application can effectively solve when the Type-C interface of external equipment has accessed the Type-C interface of electronic equipment, but electronic equipment can't carry out the problem of discerning to external equipment.
In addition, since the electronic device in the related art continuously provides the detection voltage to the configuration channel pin of the Type-C interface, the detection voltage is generally not lower than 1.5V. Thus, if exposed to a humid environment, the configuration channel pins of the Type-C interface of the electronic device are very susceptible to corrosion. In this embodiment, when it is not detected that the Type-C interface of the external device is connected to the Type-C interface of the electronic device, the configuration channel pin of the Type-C interface of the electronic device has no detection voltage. That is, the Type-C interface of the electronic device is not always live. Therefore, the scheme of the embodiment can also protect the configuration channel pins of the Type-C interface of the electronic equipment from being corroded.
Referring to fig. 3, fig. 3 is another schematic flow chart of an apparatus identification method according to an embodiment of the present disclosure. The device identification method can be applied to electronic devices. The electronic equipment provides a second detection voltage for a preset pin of a Type-C interface of the electronic equipment, and the preset pin is a non-configuration channel pin.
When the Type-C interface of the external equipment is connected with the Type-C interface of the electronic equipment, the voltage value of the preset pin of the electronic equipment is changed. When the voltage value of the preset pin is detected to change, the electronic equipment can determine that the Type-C interface of the external equipment is connected to the Type-C interface of the electronic equipment, and trigger the configuration channel pin of the electronic equipment to provide first detection voltage so as to identify the external equipment. Wherein the second detection voltage is less than the first detection voltage.
And when the Type-C interface of the external equipment is not detected to be accessed into the Type-C interface of the electronic equipment, the pin of the configuration channel of the Type-C interface of the electronic equipment has no detection voltage. That is, when it is not detected that the Type-C interface of the external device is connected to the Type-C interface of the electronic device, the electronic device does not provide the first detection voltage for the configuration channel pin of the Type-C interface of the electronic device.
In addition, in this embodiment, a preset switch is provided on the electronic device. For example, the preset switch may be a virtual switch implemented by software, or may be a physical switch implemented by hardware, and so on. When the preset switch is turned on, the electronic device executes a step of providing a first detection voltage for a configuration channel pin in a Type-C interface of the electronic device. When the preset switch is closed, the electronic device executes the step of disconnecting the external device.
The flow of the device identification method provided in this embodiment may include:
in step S201, when it is detected that the voltage value of the preset pin changes, the electronic device determines that the Type-C interface of the external device is connected to the Type-C interface of the electronic device, and triggers to provide a first detection voltage for the configuration channel pin of the electronic device.
Referring to fig. 2, in one embodiment, one or two of the pins a1, a12, B1, and B12 may be modified to change the modified pins to non-Ground (GND) pins and provide a second detection voltage to the modified pins. The second detection voltage may be a voltage with a very low value, such as 0.1V or 0.2V, etc. For example, the a1 pin may be modified such that the a1 pin becomes a non-Ground (GND) pin and a second detection voltage is provided to the a1 pin. The modified pin can be used for realizing the access detection of the Type-C interface of the external equipment. For example, the modified pin may be referred to as an access detection pin.
Since the a1, a12, B1, B12 of external devices employing a standard (fully functional) Type-C interface are all Ground (GND) pins. Therefore, when the Type-C interface of the external device is connected to the Type-C interface of the electronic device, the voltage of the A1 pin of the Type-C interface of the electronic device is pulled down, so that the connection of the external device adopting the Type-C interface is detected.
However, some external devices currently available on the market have a non-standard (non-fully functional) Type-C interface. Some of the ground pins on the Type-C interface of these external devices may not be connected to the chip of the Type-C interface, i.e., these ground pins are in the NC (not connected) state. In this way, when the Type-C interfaces of the external devices are connected to the Type-C interface of the electronic device, the voltage of the connection detection pin (e.g., the modified a1 pin) of the electronic device is not pulled low, so that the electronic device may consider that no Type-C interface of the external device is currently connected, and the electronic device may not recognize the external device using the Type-C interface.
In this embodiment, when it is detected that the voltage value of the preset pin changes, for example, when it is detected that the voltage value of the a1 pin is pulled low, the electronic device may determine that a Type-C interface of an external device is accessed to the Type-C interface of the electronic device at this time. The electronic device may then provide a first detection voltage for its configuration channel pin.
After providing the first detection voltage for the configuration channel pin, step S204 may be entered.
In step S202, the electronic device detects whether a preset switch is turned on, wherein it is determined that a preset trigger operation is received when the preset switch is turned on, the preset trigger operation being an operation received from a user to indicate that external device identification is required.
For example, when the voltage value of the preset pin is not detected to change, the electronic device may detect whether the preset switch is turned on. When the preset switch is turned on, it can be determined that the electronic device receives a preset trigger operation from a user, where the preset trigger operation is an operation for indicating that external device identification is required.
If it is detected that the preset switch is not opened, it may be considered that the identification of the external device is not currently required.
If it is detected that the preset switch is turned on, the process proceeds to step S203.
In step S203, if it is detected that the preset switch is turned on, the electronic device determines that a preset trigger operation is received, and provides a first detection voltage for a configuration channel pin in a Type-C interface of the electronic device.
For example, when the electronic device detects that the preset switch is turned on by the user, it may be determined that the electronic device receives a preset trigger operation, that is, the external device needs to be identified currently. At this time, the electronic device may provide a first detection voltage for a configuration channel pin in a Type-C interface thereof.
In step S204, after providing the first detection voltage to the configuration channel pin of the electronic device, the electronic device identifies the external device through the configuration channel pin.
For example, after providing the first detection voltage to the configuration channel pin in the Type-C interface of the electronic device, the electronic device may identify the external device through the configuration channel pin to determine what kind of device the external device is specific. For example, in some embodiments, the external device may be a device such as a headset using a Type-C interface or a USB flash drive using a Type-C interface.
In step S205, if the external device is identified as a usb disk, the electronic device controls the preset switch to maintain an operable state.
For example, the electronic device may control the preset switch to maintain an operable state if the electronic device recognizes that the current external device is a usb disk through a change in a voltage value of a configuration channel pin of a Type-C interface of the electronic device. That is, the electronic apparatus may keep the preset switch in a state of being allowed to be operated. That is, the preset switch may allow the user to switch from the turned-on state to the turned-off state or from the turned-off state to the turned-on state at this time.
In step S206, when it is detected that the preset switch is turned off, the electronic device turns off the read-write function of the usb disk.
For example, after recognizing that the current external device is a usb disk and keeping the preset switch in an operable state, if the electronic device detects that the preset switch is switched from an opened state to a closed state, the electronic device may close the read-write function of the usb disk. That is, after the read-write function of the usb disk is turned off, the electronic device cannot read or write the usb disk. If the user still needs to read and write the USB flash disk, the user needs to re-insert the USB flash disk into the electronic device.
In step S207, if it is detected that the preset switch is not turned off and the usb disk is disconnected from the electronic device, the electronic device turns off the preset switch after a preset duration.
For example, after recognizing that the current external device is a usb disk and keeping the preset switch in an operable state, if the electronic device detects that the preset switch is not turned off by a user and the usb disk is disconnected from the electronic device, for example, the user directly pulls out the usb disk from the electronic device, the electronic device may turn off the preset switch after a preset duration.
In one embodiment, the preset time period may be 5 minutes or 10 minutes, and so on. It should be noted that, when it is detected that the preset switch is not turned off by the user and the usb disk is disconnected from the electronic device, the preset switch is turned off after a preset time period, so that the user may be prevented from frequently operating the preset switch. For example, after the user uses the first usb disk, the user directly pulls the first usb disk out of the electronic device, and needs to insert the second usb disk into the electronic device for reading and writing. In this embodiment, the mode that the preset switch is turned off after the preset duration after the first usb disk is directly pulled out from the electronic device can avoid that the user needs to turn on the preset switch again. If the preset switch is directly closed after the first USB flash disk is directly pulled out of the electronic equipment, when a user needs to insert the second USB flash disk into the electronic equipment for reading and writing, the user probably needs to open the preset switch again, and therefore the operation burden of the user is increased.
In one embodiment, the preset duration may allow the user to modify and adjust, or the electronic device may record the behavior habit of the user and then adjust the preset duration according to the behavior habit of the user. For example, the electronic device obtains, through statistics, that the user rarely inserts the usb disk into the electronic device for reading and writing within 24 hours after pulling out the usb disk, and then the electronic device may adjust the preset duration to 2 minutes. Or, the electronic device obtains, through statistics, that the user will generally insert the usb disk into the electronic device for reading and writing within 2 hours after pulling out the usb disk in the last period of time, and then the electronic device may adjust the preset duration to 10 minutes, and so on.
In step S208, if it is determined that the external device is not a usb disk, the electronic device controls the preset switch to enter an inoperable state.
For example, after providing the first detection voltage for the configuration channel pin in the Type-C interface of the electronic device, the electronic device recognizes that the currently accessed external device is not a usb disk, for example, the external device is a device such as an earphone using the Type-C interface, and then the electronic device may control the preset switch to enter the inoperable state. That is, at this time, the electronic device does not allow the preset switch to be switched to another state regardless of whether the preset switch is currently in the turned-on state or the turned-off state.
For example, the currently accessed external device is an earphone adopting a Type-C interface, a user is listening to music using the earphone, and the like, if the preset switch is in a turned-off state at this time, if the preset switch is in an operable state, if the user carelessly switches the preset switch from the turned-off state to the turned-on state, the electronic device is triggered to provide a first detection voltage for a configuration channel pin in the Type-C interface of the electronic device, and the electronic device is triggered to re-identify the external device. In this way, the playing of music is interrupted, thereby affecting the user experience.
Or, the currently accessed external device is an earphone adopting a Type-C interface, the user is listening to music using the earphone, and the like, if the preset switch is in an opened state at this time, if the preset switch is in an operable state, if the user carelessly switches the preset switch from the opened state to a closed state, the electronic device is triggered to disconnect from the external device. This can also interrupt the playing of music, affecting the user experience.
In step S209, when it is detected that the external device is disconnected from the electronic device, the electronic device controls the preset switch to be switched from the inoperable state to the operable state.
For example, after recognizing that the external device is not a usb disk and controlling the preset switch to enter the inoperable state, if it is detected that the external device is disconnected from the electronic device, the electronic device may switch the preset switch from the inoperable state to the operable state.
For example, the external device is an earphone adopting a Type-C interface, and after the user listens to music, the user dials the earphone out of the electronic device, and at this time, the preset switch may be changed from an inoperable state to an operable state. For example, if the preset switch is currently in the turned-on state, the user may be allowed to switch the preset switch to the turned-off state.
In one embodiment, the step of the electronic device controlling the preset switch to switch from the inoperable state to the operable state when the external device is detected to be disconnected from the electronic device in S209 may include:
when the external device is detected to be disconnected from the electronic device through the configuration channel pin of the electronic device, the electronic device controls the preset switch to be switched from the inoperable state to the operable state.
For example, when the earphone adopting the Type-C interface is disconnected from the electronic device, the voltage of the configuration channel pin of the Type-C interface of the electronic device may become high, that is, the electronic device may detect that the electronic device is disconnected from the earphone through the voltage change of the configuration channel pin of the Type-C interface, and at this time, the electronic device may control the preset switch to be switched from the inoperable state to the operable state.
Referring to fig. 4 to 6, fig. 4 to 6 are schematic views of scenes of an identification method of a device according to an embodiment of the present application.
For example, the electronic device provided in this embodiment is an electronic device using a Type-C interface. And, the user has reformed the a1 pin of the Type-C interface of the electronic device, so that the a1 pin becomes a non-Ground (GND) pin, and the reformed a1 pin is provided with a second detection voltage. The modified pin can be used for realizing the access detection of the Type-C interface of the external equipment. For example, in this embodiment, the modified a1 pin may be referred to as an access detection pin (preset pin). Since the a1, a12, B1, B12 of external devices employing a standard (fully functional) Type-C interface are all Ground (GND) pins. Therefore, when the Type-C interface of the external device is connected to the Type-C interface of the electronic device, the voltage of the A1 pin of the Type-C interface of the electronic device is pulled down, so that the connection of the external device adopting the Type-C interface is detected.
When the Type-C interface of the external equipment is determined to be accessed into the Type-C interface of the electronic equipment, the electronic equipment can provide first detection voltage for the configuration channel pin of the electronic equipment so as to identify the external equipment. Wherein the second detection voltage is less than the first detection voltage. And when the fact that the Type-C interface of the external equipment is not detected to be connected with the Type-C interface of the electronic equipment, the electronic equipment cannot provide a first detection voltage for a configuration channel pin of the Type-C interface of the electronic equipment.
Meanwhile, a preset switch is arranged on the electronic equipment. For example, the preset switch may be a virtual switch implemented by software. When the preset switch is turned on, the electronic device executes a step of providing a first detection voltage for a configuration channel pin in a Type-C interface of the electronic device. When the preset switch is closed, the electronic device executes the step of disconnecting the external device.
For example, as shown in fig. 4, the user accesses the earphone adopting the Type-C interface to the electronic device adopting the Type-C interface provided in the present embodiment. Wherein, the Type-C interface of the earphone is not a fully functional Type-C interface, and the A1 pin (GND pin) and the B1 pin (GND pin) of the Type-C interface of the earphone are in an NC state.
In this case, although the user has accessed the Type-C interface of the headset into the Type-C interface of the electronic device, the voltage of the access detection pin (i.e., the a1 pin) of the electronic device is not pulled low because the a1 pin and the B1 pin of the Type-C interface of the headset are in the NC state. Therefore, the electronic device may consider that there is no Type-C interface access of the external device currently, i.e., the electronic device does not recognize the headset.
At this time, when the user finds that the electronic device does not recognize the earphone, the user may enter the preset switch of the setting interface and then switch the preset switch from the turned-off state to the turned-on state, as shown in fig. 5.
When it is detected that the user switches the preset switch to the turned-on state, the electronic device may provide a first detection voltage to a configuration channel pin in a Type-C interface of the electronic device.
After providing the first detection voltage for the configuration channel pin in the Type-C interface of the electronic device, the electronic device may handshake with the external device through the configuration channel pin (i.e., establish a communication connection with the external device). After the handshake with the external device is successful, the electronic device can identify the external device through the configuration channel pin of the electronic device to determine what kind of device the external device is specific. For example, in this embodiment, the electronic device recognizes that the external device is an earphone.
After the external device is identified as the earphone, the electronic device can control the preset switch to enter the non-operable state. For example, the electronic device may lock a preset switch, thereby prohibiting a user from switching the state of the preset switch. For example, a user is currently listening to music stored in an electronic device using headphones. By controlling the preset switch to enter the inoperable state, the situation that the user carelessly switches the preset switch from the turned-on state to the turned-off state to trigger the electronic equipment to be disconnected from the earphone can be avoided, and the music playing can be interrupted to influence the user experience.
And then, the electronic equipment can detect whether the user pulls the earphone out of the electronic equipment or not through a configuration channel pin of the Type-C interface of the electronic equipment. For example, after a while, as shown in fig. 6, the user pulls the earphone out of the electronic device, the voltage of the configuration channel pin of the electronic device becomes high, so that the electronic device detects that the earphone is disconnected from the electronic device. In this case, the electronic apparatus may switch the preset switch from the inoperable state to the operable state. For example, the user directly pulls out the earphone from the electronic device, in this case, the electronic device may switch the preset switch to the turned-off state after 5 minutes if it is not detected that the Type-C interface of the other external device is connected to the Type-C interface of the electronic device. The above operation flow is shown in fig. 7.
In one embodiment, after the preset switch is switched from the inoperable state to the operable state, the electronic device may then detect whether an external device is connected through the preset pin.
In one embodiment, as shown in fig. 7, if the electronic device detects that the Type-C interface of the external device is connected to the Type-C interface of the electronic device through the preset pin, the electronic device may provide a first detection voltage for its configuration channel pin, perform a handshake with the external device through the configuration channel pin (i.e., establish a communication connection), and confirm whether the handshake between the two is successful.
If the handshake between the two devices is successful, the electronic device may identify the external device and detect whether the external device is a usb disk. If the external device is detected not to be the USB flash disk, the electronic device can keep the preset switch in an operable state. And then, if the preset switch is detected to be closed by the user, the electronic equipment can close the read-write function of the USB flash disk. If it is detected that the user directly pulls out the USB flash disk from the electronic device, the electronic device can control the preset switch to enter the turned-off state after the preset duration.
If the handshake between the electronic device and the external device is unsuccessful, the electronic device may then detect whether the external device is accessed through the preset pin. Alternatively, the electronic device may attempt to handshake with the external device again, and so on.
In one embodiment, if the preset pin does not detect the external device access using the Type-C interface, the electronic device may then detect whether the external device is accessed through the preset pin.
