Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

The USB Type-C interface has two opposing pin faces, each having 12 pins, as specified by the USB association standard specification. The Type-C interface includes Configuration Channel (CCl) pins and CC2 pins on opposite pin faces. The CCl pin and the CC2 pin are used to detect positive and negative insertion, detect how much Voltage and current can be provided by USB connection identification, establish and manage connection between USB devices and a power Bus (VBUS), and the like. The voltage on the CCl pin and the CC2 pin is periodically pulled high and low.

The Dual Role Port (DRP) can be used as a downlink Port (DFP), an uplink Port (UFP), or a dynamic switch between the DFP and the UFP.

Pulse electric signals are arranged on the CCl pin and the CC2 pin, the high-level voltage value of the pulse electric signals is 1.7V-5.5V, the duty ratio is 30% -70%, and therefore the CCl pin and the CC2 pin are electrified for a long time even in a standby state. Under the condition of liquid inlet of the USBType-C interface, micro short circuit and contact impedance between pins are abnormal, so that the functional abnormality of the mobile phone interface is caused, and even a terminal short circuit and a fire disaster are caused.

Fig. 1 is a flowchart illustrating an interface control method according to an exemplary embodiment of the present disclosure, where the interface control method is used in a terminal, as shown in fig. 1. The terminal can be an electronic device such as a smart phone, a tablet computer, a wearable device or a PC machine, which is provided with a USB Type-C interface. The embodiment of the present disclosure does not limit the types of devices controlled by the application interface. Referring to fig. 1, the interface control method includes the following steps.

In step S101, an interrupt signal received by the application processor is monitored.

The interrupt signal is sent by the USB Type C interface chip in response to the dual role port switching edge of the configuration channel pin exceeding the protocol threshold.

An Application Processor (AP), an operating system, a user interface, and an Application program of the terminal are all executed on the AP. When the terminal is in a power-on running program or a standby state, the USB Type C interface chip is in a DRP mode, and pulse waveforms of a CC1 pin and a CC2 pin are square waves. The protocols of rising edge time and falling edge time of the square wave of the pin CC1 and the pin CC2 need to be in accordance with the specification.

USB Power Delivery (USB PD) corresponds to a TCPC protocol, and specifies that the rising edge time and the falling edge time of the switching square wave of the pin CC1 and the pin CC2 of the USB Type C interface chip cannot exceed a time threshold.

The specific value of the time threshold may be configured by a register, for example, the time threshold is configured to 500 microseconds.

When the rising edge time and the falling edge time of the pin CC1 and the pin CC2 exceed the time thresholds specified by the protocol specification, the USB Type C interface chip sends an interrupt to the AP.

When the terminal is in a high-temperature and high-humidity environment or the USB Type C interface is filled with liquid, for example, conductive liquid such as sweat, rain water or grease, a micro short circuit usually occurs between the CC1 pin or the CC2 pin and the adjacent VBUS pin.

When the pin CC1 or the pin CC2 is in micro short circuit with the adjacent pin VBUS, because the pin VBUS has million-level capacitance, the delay time of the rising edge and the falling delay of the falling edge of the switching square wave of the pin CC become slow and exceed the value specified by the protocol.

The USB Type C interface chip reports interruption to the AP, and the AP can be continuously awakened when the standby screen is turned off, so that large power consumption is caused.

In step S102, the number of times of reception of the interrupt signal is acquired.

The number of times the application processor AP receives the interrupt signal is obtained.

In step S103, when the number of times of reception reaches the set threshold, power supply to the interface chip is stopped.

According to the actual use requirement, a receiving frequency threshold value is set, when the receiving frequency of the AP receiving the interrupt signal reaches the set threshold value, in order to avoid that the USB Type C interface chip continuously reports the interrupt to the AP to cause the power consumption of the terminal to increase, the power supply to the USB Type C interface chip is stopped.

According to the embodiment of the disclosure, by monitoring the interrupt signal received by the application processor, the interrupt signal is sent by the interface chip when the switching edge of the dual-role port responding to the configuration channel pin exceeds the protocol threshold, the receiving times of the interrupt signal is obtained, and when the receiving times reaches the set threshold, the power supply to the USB Type C interface chip is stopped.

The Type C interface chip has a function of detecting a battery voltage threshold (dead battery), and a system cannot be started when the battery voltage threshold is lower than the dead battery voltage threshold. When the terminal battery is over-discharged, the battery voltage may become 0 v due to the battery protection board being turned off. At this time, in order to charge the terminal, a special circuit needs to be provided to allow the terminal to detect that Rd is pulled down, so that the terminal is identified as the upstream port UFP, and the terminal is charged by using the charger.

In addition, when sweat or other electrically conductive liquid exist at the USB Type C interface, the return circuit of electrochemical reaction is formed inside the interface easily, and then can cause the interface to corrode.

This openly acquires interrupt signal's receiving number of times, when receiving number of times reaches and sets up the threshold value, when the standby screen that goes out detects the USB Type C interface feed liquor promptly, stops to the power supply of USB Type C interface chip, and Type C interface chip can not send interrupt information to AP, does not awaken up AP promptly to can realize not influencing under the condition of charging, reduce the consumption, prevent simultaneously corroding, avoid the terminal to take place the short circuit, ensure user's safe in utilization.

In one embodiment of the present disclosure, the accumulated number of times of receiving the interrupt signal is obtained within a predetermined time.

USB Type C interface chip that takes place in the time of predetermineeing sends interrupt signal to AP, and the accumulative reception number of times that obtains interrupt signal reaches and predetermines the threshold value, can regard as the terminal to have the feed liquor phenomenon at USB Type C kneck. The USBType C interface chip stops supplying power, can reduce the terminal consumption that arouses by the USBType C interface feed liquor, avoids the terminal to take place the short circuit, prevents that the interface from corroding, ensures user's safe in utilization.

In one embodiment, stopping power to the interface chip includes setting a power supply voltage of the interface chip to a set value.

And setting the power supply voltage of the interface chip to a set value, and stopping or reducing power supply to the interface chip. For example, the set value may be 0 volts, i.e., power to the interface chip is stopped. Or the setting value can be 1 volt, 2 volts or a smaller voltage value less than 1 volt, so that the power supply voltage cannot maintain the normal operation of the interface chip.

Fig. 2 is a flowchart illustrating an interface control method according to another exemplary embodiment of the present disclosure. As shown in fig. 2, the interface control method further includes:

in step S201, the step of monitoring the terminal in the standby screen-off state and executing the step of monitoring the interrupt signal received by the application processor.

In step S202, the interrupt signal received by the application processor is monitored.

In step S203, the number of times of reception of the interrupt signal is acquired.

In step S204, when the number of times of reception reaches the set threshold, power supply to the interface chip is stopped.

And the USB Type C interface chip reports the interruption to the AP.

In one embodiment, the cumulative number of times of reception of the interrupt signal is acquired within a set time.

The setting time can be a preset short time, the cumulative receiving times of the interrupt signals within the setting time reach a setting threshold value, and the situation that the USBType C interface chip continuously reports the interrupt to the AP, namely, the AP is continuously wakened up, large power consumption is caused, and power supply for the interface chip is stopped is achieved.

On the contrary, when the USB Type C interface chip is interrupted, the interrupt is sent to the AP, and waking up the AP does not continuously cause the power consumption problem of the terminal.

Fig. 3 is a flowchart illustrating an interface control method according to another exemplary embodiment of the present disclosure. As shown in fig. 3, the interface control method further includes:

in step S301, an interrupt signal received by the application processor is monitored.

In step S302, the number of times of reception of the interrupt signal is acquired.

In step S303, when the number of times of reception reaches the set threshold, power supply to the interface chip is stopped.

In step S304, after the power supply voltage of the interface chip is set to the set value, it is prompted to decrease or stop supplying power to the interface chip.

When AP received interrupt signal's the number of times of receipt reached and set up the threshold value, in order to avoid USBType C interface chip to last to report to the AP that the interrupt caused the consumption increase of terminal, set up USBType C interface chip's mains voltage to 0 volt, stopped promptly to supply power to USBType C interface chip.

At this time, The terminal may be charged through The USB Type C interface, but cannot recognize and connect an OTG (On-The-Go) device. The OTG device can realize data transmission between different devices and mobile devices under the condition of no Host.

In order to avoid influencing the use of the user, the terminal can prompt the user that liquid inlet possibly exists at the USB Type C interface, and the USB Type C interface does not recognize the OTG equipment at the moment.

The terminal may prompt the user in a voice prompt mode, a pop-up window mode or the like.

For example, a sound such as a warning sound or an alarm sound is emitted to prompt the user. For another example, a voice prompt is issued. For another example, a popup window is popped up on the terminal application interface or text prompt information is popped up in the prompt area to prompt the user. The condition of USB Type C interface feed liquor is handled for the user to influence user normal use.

When the terminal is in high temperature, high humid environment or USB Type C interface feed liquor, unable discernment and connection OTG equipment. After the suggestion that user's receiving terminal probably has the condition of feed liquor to the USB Type C interface, can inspect the USB Type C interface, there is the condition of feed liquor when the reality, in time handles.

After the liquid inlet condition of the USB Type C interface is processed by the user, the USB Type C interface can be normally connected with OTG equipment

The liquid inlet condition is processed by the user, and when the USB Type C interface is required to be connected with the OTG peripheral, the operation of recovering the power supply of the interface chip can be determined.

For example, the power supply of the USB Type C interface chip can be restored by operating a power button of the terminal, a menu set by the terminal, or setting in a terminal application interface window, so that the USB Type C interface can be correctly identified and normally connected to the OTG device, thereby facilitating the use of the user.

in step S401, the interrupt signal received by the application processor is monitored.

In step S402, the number of times of reception of the interrupt signal is acquired.

In step S404, after the power supply voltage of the interface chip is set to the set value, the reduction or stop of the power supply to the interface chip is prompted

In step S405, the power supply of the interface chip is restored in response to the operation of restoring the power supply of the interface chip.

After the suggestion that USB Type C interface probably has the condition of feed liquor when user's receiving terminal, can check USB Type C interface, even handle when the condition that really has the feed liquor.

In one embodiment, the step of monitoring the interrupt signal received by the application processor is performed after the power supply of the interface chip is restored.

After the power supply of the interface chip is recovered, the interrupt signal received by the application processor is monitored, if the USBType C interface is detected to still have liquid or the liquid inlet condition is not successfully processed, when the frequency of receiving the interrupt signal reaches a set threshold value, the power supply for the interface chip is stopped, and the use safety of the terminal is ensured.
