Referring to fig. 2, fig. 2 is a schematic flow chart of an apparatus detection method according to an embodiment of the present disclosure. The specific process of the device detection method provided by the embodiment of the application can be as follows:

in step 101, whether external objects exist in the Type-C interface is detected.

Referring to fig. 3, the Type-C interface of the electronic device includes an interface portion and a housing portion, and the housing portion surrounds the interface portion, as shown in fig. 3, the housing portion surrounds the interface portion to form a receiving space, which is accessible to the Type-C interface of the external Type-C device, so that the electronic device and the external Type-C device are electrically connected. The external Type-C device can be an earphone adopting a Type-C interface, a U disk adopting a Type-C interface, a mobile phone adopting a Type-C interface, a tablet computer adopting a Type-C interface, a notebook computer adopting a Type-C interface, a desktop computer adopting a Type-C interface and other electronic devices.

In the embodiment of the application, whether an external object exists in the Type-C interface is detected, namely whether the external object exists in an accommodating space formed by the interface part and the shell part of the Type-C interface is detected.

For example, after the user accesses the Type-C interface of the external Type-C device to the Type-C interface of the electronic device, the electronic device will detect that the external object is stored in the Type-C interface.

In step 102, when an external object is stored in the Type-C interface, a preset detection voltage is provided for a configuration channel pin of the 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, respectively, where when the Type-C interface of the electronic device is used as the downlink interface, the electronic device is used as a master device, and can supply power to an accessed external Type-C device, send data to the external Type-C device, read data from the external Type-C device, and so on; when the Type-C interface of the electronic equipment is used as an uplink interface, the electronic equipment is used as slave equipment, and can be powered off from the accessed external Type-C equipment to provide data and the like 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.

In addition, the biggest characteristics of Type-C interface are that support all can insert "positive and negative the inserting" function on positive and negative two sides, and for realizing "positive and negative the inserting" function, the positive and negative two sides of its interface portion all is provided with 12 pins, and the pin definition is as shown in following table 1:

TABLE 1

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 USB2 and 0 standards, VBUS is a power supply pin, CC1 and CC2 are configuration channel pins, and SBU1 and SBU2 are bus pins.

Wherein, through configuration channel pin, electronic equipment can realize that the access of outside Type-C equipment detects, role differentiation and positive and negative discernment etc..

In the embodiment of the application, when a Type-C interface memory is detected as an external object, that is, it is stated that there may be an external Type-C device to be accessed currently, at this time, a preset detection voltage may be provided for a configuration channel pin of the Type-C interface, so as to implement access detection of the external Type-C device based on the configuration channel pin.

The preset detection voltage can be a pulse width modulation voltage, the voltage range can be 2.4V to 3.4V, the period range can be 50ms to 100ms, and the duty ratio range can be 30% to 70%.

For example, when the electronic device detects an external object stored in the Type-C interface, a preset detection voltage with a voltage value of 3.4V, a period of 50ms, and a duty cycle of 70% is provided to the configuration channel pin of the Type-C interface.

In step 103, a voltage variation value of the configuration channel pin is obtained.

In the embodiment of the application, after the preset detection voltage is provided for the Type-C interface, voltage detection is performed on the configuration channel pin, the current voltage of the configuration channel pin is obtained, the voltage difference value between the preset detection voltage and the current voltage is calculated, and the calculated voltage difference value is used as the voltage change value of the configuration channel.

In step 104, whether the external object is an external Type-C device is determined according to the voltage variation value.

In the embodiment of the application, the Type-C interface of the electronic device is configured as a downlink interface, that is, the electronic device serves as a master device. When the Type-C interface of the external Type-C 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 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 Type-C device is connected to the Type-C interface of the electronic device, the configuration channel pin of the electronic device will be connected to the configuration channel pin of the external Type-C device, so that the configuration channel pin of the electronic device is connected to the pull-down resistor of the external Type-C device, and the voltage on the configuration channel pin of the electronic device is pulled down.

Therefore, the electronic device can judge whether the external object existing in the Type-C interface of the electronic device is the external Type-C device (specifically, the Type-C interface of the external Type-C device) according to the voltage change value of the configuration channel pin of the electronic device.

It should be noted that, for external Type-C devices with different functions (for example, an earphone and a usb disk that use a Type-C interface), the resistance values of the pull-down resistors connected to the configuration channel pins of the external Type-C devices are different, and correspondingly, when the external Type-C devices with different functions are connected to the electronic device, the voltage pull-down degrees of the configuration channel pins of the electronic device are different. Therefore, a preset voltage interval can be set to reflect the voltage reduction degree of the external Type-C device with different functions, for example, the preset voltage interval can be set to [ Vmin, Vmax ], Vmin is the minimum voltage value of the configuration channel pin of the electronic device when the external Type-C device is connected to the electronic device, and Vmax is the maximum voltage value of the configuration channel pin of the electronic device when the external Type-C device is connected to the electronic device. The values of Vmin and Vmax may be determined in advance through experiments, for example, if the determined Vmin is 1.5V and the determined Vmax is 3V, the preset voltage interval [1.5V, 3V ] may be obtained.

In the embodiment of the application, when judging whether the external object is an external Type-C device or not according to the voltage change value, the electronic device can judge whether the obtained voltage change value is within a preset voltage interval or not; if the voltage change value is within the preset voltage interval, the electronic equipment determines that the external object is external Type-C equipment; if the voltage variation value is outside the preset voltage interval, the electronic device determines that the external object is not an external Type-C device.

For example, when the preset voltage interval is [1.5V, 3V ], if the electronic device obtains that the voltage variation value of the pin of the configuration channel is 2V, it may be determined that the external object in the Type-C interface is an external Type-C device; if the electronic device obtains that the voltage variation value of the configuration channel pin is 0.2V, it can be determined that the external object in the Type-C interface is not the external Type-C device.

According to the method, whether the external object exists in the Type-C interface is detected; when an external object is stored in the Type-C interface, providing a preset detection voltage for a configuration channel pin of the Type-C interface; acquiring a voltage change value of a configuration channel pin; and judging whether the external object is external Type-C equipment or not according to the voltage change value. In the scheme, the power supply for the configuration channel pin of the Type-C interface is not required to be continuously realized, but an external object exists in the Type-C interface when the Type-C interface is detected, namely the Type-C interface can be connected into external Type-C equipment, the preset detection voltage is provided for the configuration channel pin, the connection detection for the external Type-C equipment is realized, therefore, the power supply for the configuration channel pin is only required within a short time, the corrosion of the external Type-C equipment connection detection on the Type-C interface is reduced, and the purpose of prolonging the service life of the Type-C interface is achieved.

In one embodiment, referring to fig. 4, to implement the detection of the external object inside and outside the Type-C interface, a distance sensor may be disposed on a housing portion of the Type-C interface, and a detection end of the distance sensor is disposed toward an interface portion of the Type-C interface to detect whether the external object exists inside the Type-C interface, including:

acquiring a distance value detected by a distance sensor;

and judging whether the acquired distance value is within a preset distance interval, wherein if the acquired distance value is within the preset distance interval, the Type-C interface is stored in an external object.

It should be noted that, in the embodiment of the present application, no specific limitation is imposed on what Type of distance sensor is used, and a person skilled in the art may select any one of different types of distance sensors such as a laser distance sensor, an infrared distance sensor, and an ultrasonic distance sensor according to actual needs, for example, in the embodiment of the present application, an infrared distance sensor is disposed on a housing portion of a Type-C interface, and a detection end of the infrared distance sensor faces the interface portion.

As shown in FIG. 4, the distance sensor disposed in the housing portion will detect its own distance value to the interface portion when no external object is present in the Type-C interface, and will detect its own distance value to the Type-C interface of the external Type-C device when an external object, such as an external Type-C device, is present in the Type-C interface.

It is easy to understand that, when no external object exists in the Type-C interface of the electronic device, it is obviously impossible for the external Type-C device to access, and when an external object exists in the Type-C interface of the electronic device, the external Type-C device may be accessed only, so in this embodiment of the application, the electronic device may determine whether an external object exists in the Type-C interface according to the distance value detected by the distance sensor, so as to preliminarily determine whether an external Type-C device accesses.

In the embodiment of the application, when detecting whether an external object exists in the Type-C interface, the electronic device firstly obtains a distance value detected by the distance sensor, then judges whether the obtained distance value is located in a preset distance interval, determines that the external object exists in the Type-C interface when the obtained distance value is located in the preset distance interval, and determines that the external object does not exist in the Type-C interface when the obtained distance value is located outside the preset distance interval.

The preset distance interval can be set to be [0, Lmax ], when the Lmax indicates that external Type-C equipment is connected to the Type-C interface of the electronic equipment, the maximum distance value which can be detected by the distance sensor (when the thicknesses of the Type-C interfaces of different external Type-C equipment are different, and different external Type-C equipment are connected to the Type-C interfaces of the electronic equipment, the distance value detected by the distance sensor is different), and the maximum distance value can be obtained in advance through experiments.

For example, the preset distance interval is set to [0,0.5mm ], and if the obtained distance value is 1mm (if no external Type-C device is connected to the Type-C interface of the electronic device), the electronic device detects that no external object exists in the Type-C interface;

if the obtained distance value is 0.2mm (if an external Type-C device is connected to a Type-C interface of the electronic device), the electronic device detects that the Type-C interface of the electronic device is stored in an external object.

In one embodiment, to detect the external object in the Type-C interface, a first brightness sensor may be disposed on the housing portion of the Type-C interface, and a detection end of the first brightness sensor faces the interface portion, a second brightness sensor may be disposed at a position outside the Type-C interface, and a detection end of the second brightness sensor faces a direction away from the electronic device, so as to detect whether the external object exists in the Type-C interface, including:

acquiring a first brightness value detected by a first brightness sensor;

acquiring a second brightness value detected by a second brightness sensor;

and acquiring a brightness difference value between the first brightness value and the second brightness value, and judging whether the brightness difference value reaches a preset brightness difference value, wherein when the brightness difference value reaches the preset brightness difference value, determining that the Type-C interface is stored in an external object.

It is easy to understand that, when no external object exists in the Type-C interface of the electronic device, the brightness difference between the first brightness sensor disposed in the Type-C interface and the second brightness sensor disposed outside the Type-C interface (the difference between the brightness values detected by the two brightness sensors) is small, and when an external object exists in the Type-C interface of the electronic device (for example, the Type-C interface of the external Type-C device connected to the electronic device), the external object blocks the light emitted to the first brightness sensor, so that the brightness difference between the first brightness sensor and the second brightness sensor is large. Therefore, the electronic equipment can determine whether external objects exist in the Type-C interface according to the brightness difference value of the first brightness sensor and the second brightness sensor.

It should be noted that, for the specific value of the preset luminance difference, the embodiment of the present application is not particularly limited, and may be set by a person skilled in the art according to actual needs.

In one embodiment, referring to fig. 5, to detect an external object inside and outside a Type-C interface, an electronic device includes a detection circuit, the detection circuit includes a metal contact, a detection voltage providing module and a detection resistor, wherein one end of the metal contact passes through a through hole formed in a housing portion and is fixed to a middle frame of the electronic device, and the other end of the metal contact passes through another through hole formed in the housing portion and extends into the electronic device to connect the detection voltage providing module and the detection resistor when a deformation occurs, so as to detect whether the external object exists inside the Type-C interface, including:

acquiring an input voltage value of a detection resistor;

if the obtained input voltage value is the same as the output voltage value of the detection voltage providing module, an external object is stored in the Type-C interface.

The detection resistor may be a single resistor, or may be formed by connecting a plurality of resistors in series and/or in parallel, and the selection of the resistance value may be a suitable value according to actual needs by those skilled in the art, which is not specifically limited in the embodiment of the present application, and may be set to 1.2K Ω, for example.

For example, referring to fig. 5, the output voltage value of the detection voltage providing module is 3.7V, when no external Type-C device is connected, the metal contact plate will not deform, and the input voltage value of the electronic device to the detection resistor is zero; when external Type-C equipment is connected, the Type-C interface of the external Type-C equipment extrudes the metal contact plate to deform the metal contact plate, so that the detection voltage providing module and the detection resistor are connected, the input voltage value of the detection resistor acquired by the electronic equipment is the same as the output voltage value of the detection voltage providing module at the moment, the input voltage value is 3.7V, and the external object stored in the Type-C interface is detected.

In an embodiment, after providing the preset detection voltage for the configuration channel pin of the Type-C interface, the method further includes:

when detecting that there is not external article in the Type-C interface, stop providing for configuration channel pin and predetermine detection voltage.

The step of detecting whether an external object exists in the Type-C interface is carried out in real time, and at a certain moment, if the external object is detected in the Type-C interface, preset detection voltage is provided for the Type-C interface so as to realize access detection of external Type-C equipment.

After providing the preset detection voltage for the configuration channel pin of the Type-C interface, that is, during the period of providing the preset detection voltage for the configuration channel pin of the Type-C interface, the electronic device still detects whether the external object exists in the Type-C interface in real time, wherein for how to detect whether the external object exists in the Type-C interface, the above related description may be specifically referred to, and details are not repeated here.

When it is detected that no external object exists in the Type-C interface (for example, after the user accesses the external Type-C device to the Type-C interface of the electronic device, the external Type-C device is pulled out from the Type-C interface of the electronic device), the electronic device stops supplying power to the configuration channel pin of the Type-C interface of the electronic device, so that the configuration channel pin is not electrified.

In short, in the embodiment of the present application, during the period that the electronic device is and only has an external object in the Type-C interface, the electronic device provides a preset detection voltage for the configuration channel pin of the Type-C interface, so as to implement access detection on the external Type-C device, and when there is no external object in the Type-C interface, the electronic device does not supply power to the configuration channel pin, so that the configuration channel pin is not powered.

In an embodiment, after determining whether the external object is an external Type-C device according to the voltage variation value, the method further includes:

if the external object in the Type-C interface is external Type-C equipment, establishing electrical connection with the external Type-C equipment through the Type-C interface;

according to the voltage change value of the configuration channel pin, corresponding power supply voltage is provided for the external Type-C equipment through the established electric connection, and power is supplied for the external Type-C equipment.

In the embodiment of the application, the electronic equipment serves as a master device, the external Type-C equipment serves as a slave device and is connected with the electronic equipment, and electric connection is established between the electronic equipment and the external Type-C equipment.

Based on the above description about "determining whether the external object is an external Type-C device according to the voltage variation value", it can be known that, when the external Type-C devices with different functions are connected to the electronic device, the voltage variation values detected by the electronic device on the configuration channel pins are different. In addition, as can be known by those skilled in the art, the power supply voltage required by the external Type-C device with different functions is different, for example, the power supply voltage required by the earphone adopting the Type-C interface is 3.3V, and the power supply voltage required by the usb flash disk adopting the Type-C interface is 4.5V.

Therefore, in the embodiment of the present application, a corresponding relationship between the voltage variation value and the power supply voltage is preset. Correspondingly, when the electronic equipment detects that the Type-C interface is internally stored in an external object and determines that the external object is the external Type-C equipment, the electronic equipment determines the power supply voltage corresponding to the acquired voltage change value according to the acquired voltage change value of the pin of the configuration channel and the corresponding relation between the voltage change value and the power supply voltage, and provides the determined power supply voltage for the external Type-C equipment through the established electric connection.

Therefore, the function Type of the external Type-C device can be further identified by configuring the voltage change value on the channel pin, and a corresponding power supply voltage is provided for the external Type-C device.

It is easy to understand that if the temperature of the Type-C interface is too high, it will be possible to burn out the Type-C interface and even damage the whole electronic device. And when the electronic equipment supplies power for the external Type-C equipment through the Type-C interface, the temperature of the Type-C interface of the electronic equipment is rapidly increased. In order to avoid the damage of the electronic device caused by the power supply of the external Type-C device, in an embodiment, the method further comprises the following steps:

acquiring a temperature value of a Type-C interface during the period of providing power supply voltage for external Type-C equipment;

and when the acquired temperature value is within the preset temperature interval, disconnecting the electric connection with the external Type-C equipment.

Referring to fig. 6, a temperature sensor may be further disposed on a housing portion of the Type-C interface, and is used to detect a temperature of the Type-C interface.

In the embodiment of the application, during the period that the electronic device provides the power supply voltage for the external Type-C device, the temperature value of the Type-C interface is acquired from the temperature sensor arranged on the Type-C interface in real time, and after the temperature value of the Type-C interface is acquired, whether the temperature value is within the preset temperature range is judged, wherein when the temperature value is within the preset temperature range, the temperature of the Type-C interface is over high, at the moment, the electric connection with the external Type-C device is disconnected, so that the power supply to the external Type-C interface is stopped, and the temperature of the Type-C interface is prevented from being continuously increased.

The preset temperature interval may be set to [ Tmin, + ∞), [ Tmin ] indicates the lowest temperature value that may cause damage to the electronic device, and may be obtained in advance through experiments.

For example, the preset temperature interval is set to [60 ℃, + ∞ ], if the obtained temperature value of the Type-C interface is 37 ℃, the electronic device continues to supply power to the external Type-C device; and if the obtained temperature value of the Type-C interface is 67 ℃, the electronic equipment is disconnected from the electric connection with the external Type-C equipment, and the power supply for the external Type-C equipment is stopped.

In an embodiment, when the obtained temperature value is within the preset temperature interval, the step of disconnecting the electrical connection with the external Type-C device includes:

when the obtained temperature value is within a preset temperature interval, displaying an information input window;

upon receiving the inputted confirmation information based on the displayed information input window, the electrical connection with the external Type-C device is disconnected.

In the embodiment of the application, whether the electrical connection with the external Type-C device is disconnected or not is determined by a user. For example, referring to fig. 7, when the electronic device acquires a temperature value of the Type-C interface and determines that the temperature value is within a preset temperature range, an information input window is displayed in a screen display area, where the information input window includes a yes control and a no control, and prompt information that prompts a user whether to disconnect the external Type-C device is that "the current temperature is too high and the external device is disconnected", and the user can input confirmation information by clicking the yes control and input denial information by clicking the no control.
