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 flowchart 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 first 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. 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.
The flow of the device identification method provided in this embodiment may include:
in 101, when an instruction for instructing the external device identification is received from a user, a preset pin is grounded.
Currently, the USB interfaces used on many electronic devices are 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 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.
Referring to fig. 3, fig. 3 is a pin arrangement diagram of a Type-C plug interface in the related art.
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 the access detection of the Type-C interface of the external device through the configuration channel pin of the Type-C interface. 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 the configuration channel pin of its Type-C interface to discern external equipment.
In this embodiment, the electronic device detects whether there is a Type-C interface of the external device to access the Type-C interface of the electronic device through a preset pin of the Type-C interface. The preset pin is a non-configuration channel pin, and the electronic device provides a first detection voltage for the preset pin. For example, the preset pin may be any one, two or more of the pins a1, B1, a12 and B12 in fig. 2. That is to say, in this embodiment, one, two, or more pins of a1, B1, a12, and B12 may be modified, so that the modified pin is changed to a non-Ground (GND) pin, and the modified pin is determined to be a preset pin, where the preset pin may be used to perform access detection on a Type-C interface of an external device. For example, the modified pin may also be referred to as an access detection pin. In some embodiments, the first detection voltage may be a voltage with a very low value, such as 0.1V or 0.2V, etc.
In one embodiment, the a1, a12, B1, B12 of the external device are all Ground (GND) pins because of the standard (full function) Type-C interface. 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 preset pin of the Type-C interface of the electronic device is pulled down (changed to zero from the first detection voltage), 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. Only one of the A1, B1, A12, B12 of the Type-C interface of these external devices is connected to the chip of the Type-C interface, while the remaining three pins are not connected to the chip of the Type-C interface, i.e., the three pins are in NC (Notconnected) state. For example, only the A1 pin in the Type-C interface of the external device is connected with the chip of the Type-C interface, and the three pins B1, A12 and B12 are in the NC state. In this way, when the Type-C interface (only the a1 pin may be grounded) of the external device is connected to the Type-C interface of the electronic device provided in this embodiment (for example, the a1 pin is modified to be a preset pin), since no other pin of the Type-C interface of the external device can be connected to the ground pin in the Type-C interface of the electronic device, a ground loop cannot be formed between the external device and the electronic device, and the a1 pin of the external device cannot pull down the voltage of the a1 pin of the electronic device, the electronic device may consider that the Type-C interface of the external device is not connected currently, and the electronic device may not identify the external device adopting the Type-C interface.
In 101 of the embodiment of the present application, when an instruction for instructing to perform external device identification is received from a user, the electronic device may ground the preset pin. For example, the pin is a1 pin, i.e., the electronic device can ground the a1 pin of its Type-C interface.
At 102, when the preset pin is detected to be grounded, a trigger signal is generated.
For example, when the electronic device connects the a1 pin of the Type-C interface to ground, the detection voltage of the a1 pin is changed from the first detection voltage to zero, and the electronic device can detect that the a1 pin is connected to ground. When the a1 pin is detected as being grounded, the electronic device may generate a trigger signal.
In one embodiment, the trigger signal may be an interrupt signal or the like.
In 103, a second detection voltage is provided for the configuration channel pin according to the trigger signal, wherein the second detection voltage is greater than the first detection voltage.
At 104, after providing the second detection voltage to the configuration channel pin, the external device is identified through the configuration channel pin.
For example, 103 and 104 may include:
after generating the trigger signal, the electronic device may provide a second detection voltage for a configuration channel pin of a Type-C interface thereof. The second detection voltage may be greater than the first detection voltage. For example, the second detection voltage may be 1.5V or the like.
After providing the second detection voltage for the configuration channel pin, 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 this embodiment, when an external device with only one pin in the Type-C interface capable of being grounded needs to be identified, a user may send an instruction to the electronic device, that is, the electronic device may receive an instruction for instructing to perform external device identification. At this moment, the electronic device can actively ground the preset pin, and when the preset pin is grounded, the electronic device can be triggered to provide a second detection voltage for the configuration channel pin of the Type-C interface of the electronic device, so that the external device can be identified through the configuration channel pin. Therefore, the problem that the external equipment which only has one pin and can be grounded in the Type-C interface cannot be identified can be effectively solved by the embodiment.
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. 4, fig. 4 is another schematic flow chart of the device identification method according to the 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 pin of the configuration channel of the Type-C interface of the electronic equipment has no detection voltage. The electronic equipment provides a first 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. The preset pin can be selectively grounded through the first switch, that is, when the first switch is in an on state, the preset pin can be grounded.
The electronic device is provided with a second switch. The second switch may be a virtual switch implemented by software, or may be a physical switch implemented by hardware. When the second switch is turned on by the user, it may be determined that an instruction for instructing the identification of the external device is received from the user.
The flow of the device identification method provided in this embodiment may include:
in 201, when an instruction for instructing external device identification is not received from a user and it is detected that the voltage value of the preset pin becomes zero, the electronic device determines that the Type-C interface of the external device is accessed to the Type-C interface of the electronic device.
For example, the predetermined pin of the Type-C interface of the electronic device is the a1 pin, that is, the a1 pin of the Type-C interface of the electronic device is modified to be a non-ground pin, and the electronic device provides the a1 pin with a first detection voltage, for example, the first detection voltage is 0.1V.
Then, when an instruction for instructing the external device to recognize is not received from the user and the electronic device detects that the voltage value of the a1 pin of the Type-C interface of the electronic device has the first detection voltage changed to zero, the electronic device may determine that the Type-C interface of the external device is connected to the Type-C interface of the electronic device.
After 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 enters 205, namely the electronic equipment is triggered to provide second detection voltage for the configuration channel pin of the Type-C interface. The electronic device may then identify the external device by configuring the channel pin.
At 202, when it is detected that the second switch is turned on by the user, the electronic device determines that an instruction for instructing the external device to recognize is received from the user.
For example, the second switch is a virtual switch implemented by software. Then, when it is detected that the second switch is turned on by the user, the electronic device may determine that an instruction for instructing the external device to be recognized is received from the user.
In 203, the electronic device controls the first switch to enter an on state when receiving an instruction for instructing external device identification from a user, and the preset pin is grounded when the first switch is in the on state.
For example, when it is determined that an instruction for instructing the external device to recognize is received from the user, the electronic device may control the first switch to be in an on state, and when the first switch is in the on state, the a1 pin is grounded.
At 204, the electronic device generates a trigger signal when the preset pin is detected to be grounded.
For example, when the electronic device connects the a1 pin of the Type-C interface to ground, the detection voltage of the a1 pin is changed from the first detection voltage to zero, and the electronic device can detect that the a1 pin is connected to ground. When the a1 pin is detected as being grounded, the electronic device may generate a trigger signal.
At 205, the electronic device provides a second detection voltage to the configuration channel pin, the second detection voltage being greater than the first detection voltage.
For example, after generating the trigger signal, the electronic device may provide the second detection voltage to the configuration channel pin of the Type-C interface thereof according to the trigger signal. The second detection voltage may be greater than the first detection voltage. For example, the second detection voltage may be 1.5V or the like.
Or when the electronic equipment determines that the Type-C interface of the external equipment is connected to the Type-C interface of the electronic equipment, the electronic equipment can provide a second detection voltage for the configuration channel pin of the Type-C interface.
At 206, the electronic device identifies the external device through the configuration channel pin after providing the second detection voltage to the configuration channel pin.
For example, after providing the second detection voltage to the configuration channel pin, 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 some other embodiments, in addition to the second switch being provided for determining whether an instruction for instructing the external device to be recognized is received from the user, the electronic device may determine whether an instruction for instructing the external device to be recognized is received from the user as follows.
In one embodiment, the step of receiving an instruction from a user to perform external device identification may include:
when the display screen in the screen-saving state receives a touch operation of a preset track, the electronic equipment determines that an instruction for indicating external equipment identification is received from a user.
For example, the predetermined trajectory is an "o" shape. Then, if the display screen is in a screen-off state and the user draws an "o" shaped track on the display screen, the electronic device may receive a touch operation of a preset track, and at this time, the electronic device may determine that an instruction for instructing to perform external device identification is received from the user.
In another embodiment, the step of receiving an instruction from a user to perform external device identification may include:
when receiving the voice command of the preset content, the electronic equipment determines that the command for instructing the external equipment identification is received from the user.
For example, the voice command of the preset content is "xiaohu, and the external device is recognized through the Type-C interface". Then, when the user issues a voice command of "small europe, recognizing the external device through the Type-C interface" to the electronic device, the electronic device may determine that a command for instructing the external device to be recognized is received from the user.
In one embodiment, after the electronic device provides the second detection voltage to the configuration channel pin thereof, whether the external device is identified within a preset time period may also be detected. If the external device is not identified within the preset time, that is, although the user turns on the second switch to enable the electronic device to provide the second detection voltage for the configuration channel pin, the user does not access the external device to the electronic device within the preset time. In this case, the electronic device may disconnect the second detection voltage of the configuration channel pin, leaving the configuration channel pin uncharged.
Referring to fig. 5 to 7, fig. 5 to 7 are schematic views of a scene of an apparatus identification method 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 first detection voltage. The modified A1 pin can be used for realizing the access detection of the Type-C interface of the external equipment. The modified a1 pin can be selectively grounded through the first switch, i.e., the a1 pin can be grounded when the first switch is in an on state. 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. The electronic device is provided with a second switch. The second switch is a virtual switch implemented by means of software. When the second switch is turned on by the user, it may be determined that an instruction for instructing the identification of the external device is received from the user.
For example, as shown in fig. 5, the user accesses the earphone adopting the Type-C interface to the electronic device adopting the Type-C interface provided in the present embodiment.
If the Type-C interface of the earphone is a fully functional Type-C interface, namely, all of the A1, B1, A12 and B12 are Ground (GND) pins. In this case, when the Type-C interface of the headset 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 low, i.e., becomes zero from the first detection voltage. When detecting that the voltage of the a1 pin of the Type-C interface becomes zero, the electronic device can determine that there is an access of an external device of the Type-C interface. Then, the electronic device may provide a second detection voltage for the configuration channel pin of the Type-C interface of the electronic device, and identify what kind of device the external device is according to the voltage variation value of the configuration channel pin. For example, by configuring the voltage variation value of the channel pin, the electronic device recognizes that the external device is specifically a headset employing a Type-C interface.
If the Type-C interface of the earphone is not a fully functional Type-C interface, for example, the a1 pin of the Type-C interface of the earphone is connected to the chip of the Type-C interface, that is, the a1 pin of the Type-C interface of the earphone can be grounded, and B1, a12, and B12 are all in an NC state. In this case, when the Type-C interface of the earphone is connected to the Type-C interface of the electronic device, for example, the a1 pin of the earphone is connected to the a1 pin of the electronic device, because no other pin of the Type-C interface of the earphone can be connected to the ground pin of the Type-C interface of the electronic device, a ground loop cannot be formed between the earphone and the electronic device, and further the voltage of the a1 pin of the electronic device cannot be pulled down by the a1 pin of the earphone, the electronic device may consider that no Type-C interface of the external device is currently connected, that is, the electronic device may not provide the second detection voltage for the configuration channel pin of the Type-C interface of the electronic device, that is, the electronic device does not identify the external device using the Type-C interface.
In this case, when the user finds that the electronic device does not recognize the headset, the user may enter the second switch of the setting interface and then switch the second switch from the turned-off state to the turned-on state, as shown in fig. 6.
After detecting that the user turns on the second switch, the electronic device may determine that an instruction for instructing the external device to recognize is received from the user. The electronic device may then control the first switch to enter an on state, and when the first switch is in the on state, the a1 pin of the Type-C interface of the electronic device is grounded.
For example, in one embodiment, as shown in FIG. 7, the A1 pin of the electronic device is connected to ground through a TFT switch. Three ends of the TFT switch are respectively connected with the A1 pin of the electronic device, the first switch control circuit and the ground. When it is determined that an instruction for instructing the external device to be recognized is received from the user, the electronic device may transmit a high level signal to the first switch control circuit, thereby turning on the first switch. When the first switch is turned on, the a1 pin of the electronic device is connected to ground.
When detecting that the a1 pin of the electronic device is grounded, the electronic device may generate a trigger signal and provide a second detection voltage to the configuration channel pin in the Type-C interface thereof according to the trigger signal. After the second detection voltage is provided 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.
In one embodiment, as shown in fig. 8, a resistor may be connected to the end of the TFT switch connected to ground. The resistor can prevent the A1 pin of the electronic device from being burnt out by external large current.
Referring to fig. 9, fig. 9 is a schematic structural diagram of an apparatus identification device according to an embodiment of the present application. The device identification apparatus can be applied to electronic devices. The electronic equipment provides a first 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 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.
The device-identifying apparatus 400 may include: the system comprises a control module 401, a generation module 402, a configuration module 403 and an identification module 404.
The control module 401 is configured to ground the preset pin when receiving an instruction for instructing to perform external device identification from a user.

In one embodiment, the predetermined pin is selectively grounded through a first switch.
The control module 401 may be configured to: when an instruction for indicating external equipment identification is received from a user, the first switch is controlled to enter an on state, and when the first switch is in the on state, the preset pin is grounded.
