Description

Technical Field

[0001] The present disclosure relates to the technical field of interface detection, and particularly to an interface detection method, apparatus, computer device, and storage medium. Background Art

[0002] During the daily use of device interfaces, over time, corrosion and aging between interface pins are a common problem.

[0080] During the daily use of a device interface, over time, corrosion and aging between interface pins are a common problem, that is, the interface pins may become unreliable due to oxidation, chemical reactions, moisture, dust, or other external factors, which may lead to problems such as data transmission errors and signal loss between the device and the connector, and even cause the interface to overheat and the device to malfunction.

[0081] In related technologies, generally, it is necessary to rely on manual experience to complete the detection of the interface, and the accuracy rate is relatively low. At the same time, since it is difficult for users to notice the health status of the device interface usually, it is even possible that the interface is abnormal but not discovered by the user, resulting in device failures.

[0082] In view of this, the present disclosure provides an interface detection method, device, computer device, and storage medium. First, an exemplary introduction to the application scenarios and concepts involved in the present disclosure will be given below.

[0083] In the present disclosure, a connector is a device used to connect electronic components, circuit boards, or cables, such as a USB-C (Universal Serial Bus Type-C) connector, a Micro USB connector (Micro Universal Serial Bus interface), etc. The connector and its corresponding interface usually have a specific physical shape and pin layout, and can be used to provide or receive electrical energy and conduct data transmission. An interface is a connection point or contact point between a connector and an external device or system, such as metal pins, pins, or sockets. In actual applications, the interface is usually located on the device or is connected to the device through a virtual or physical medium. In the present disclosure, a device may have one or more connection interfaces, and the present disclosure does not limit the quantitative relationship between the connection interfaces and the device. By reusing the method provided in the present disclosure, an interface detection method for multiple interfaces on the same device can be obtained.

[0084] Next, the embodiments of the present disclosure will be described in detail.

[0085] The first aspect of the present disclosure provides an interface detection method. Please refer toFigure 1 , which includes the following steps:

[0086] Step S101, during the change process of the first voltage, collect the first preset type of characteristics of the first voltage, where the first voltage is the voltage between the first pin and the second pin on the interface.

[0087] Wherein, the first pin and the second pin are two pins on the interface, and the first preset type of characteristics can be the rising slope, falling slope, maximum voltage of the first voltage in the line graph or curve graph of voltage changing with time, the voltage corresponding to when the first voltage does not change within a preset time threshold, etc. In addition, it can also be the average value determined based on multiple characteristic values of the same type, or the comprehensive value determined based on the above multiple types of characteristics according to a preset formula.

[0088] The change of the first voltage can be caused by the connection of the interface and the connector (that is, during the change process of the first voltage, collecting the preset type of characteristics of the first voltage includes collecting the preset type of characteristics of the first voltage during the change process of the first voltage after the interface and the connector are connected), or can be caused by the device actively sending an electrical signal (for example, in a preset dedicated detection scenario, the device will cause the voltage change of one or more pins on the interface). In addition, the method may further include stopping the change of the first voltage in response to the first voltage reaching the voltage threshold.

[0089] In other words, the change of the first voltage can be caused by inserting the connector. For example, when a charger is inserted, the charger will provide a voltage that continuously increases and finally stabilizes at the voltage threshold to the device based on a preset protocol and preset pins. Another example is that when the device is connected to a flash drive, the device will provide a voltage that continuously increases and finally stabilizes at the voltage threshold to the flash drive based on a preset protocol and preset pins. And between the preset pins and other pins (such as the ground wire pin), a changing voltage will be formed. The above conditions add a trigger condition and a cut-off condition to the interface detection method, ensuring the timeliness of the interface detection. At the same time, it avoids the method from collecting invalid data (such as voltage changes caused by static electricity) resulting in incorrect judgment results, and further improves the accuracy of the method.

[0090] Step S102, in response to the difference between the first preset type of characteristics and the first reference value being greater than the first threshold, determine that the interface is in an abnormal state, where the first reference value represents the value of the first preset type of characteristics of the first voltage when the interface is in a normal state.

[0091] Among them, the first reference value can be determined by pre - conducted experiments or by the device receiving instructions or data packets from users or the network. When the difference between the first preset - type feature and the first reference value is greater than the first threshold, it can be determined that the interface is in an abnormal state, that is, the interface may be in a state of excessive corrosion, aging, or being contaminated with foreign objects, etc.

[0092] In the present disclosure, the first pin can be a power - supply pin, a configuration - channel pin, etc., and the second pin can be a ground - wire pin, a spare pin, etc. The specific situation can be determined according to the interface type and the detection requirements. Here, taking the first pin as the VBUS pin on USB - C and the second pin as the GND pin on USB - C as an example to further illustrate the detection principle of the present disclosure, please refer to Figure 2 , which shows an equivalent RC (resistance - capacitance) circuit formed between the VBUS pin (power - supply pin) and the GND pin (ground - wire pin) on the USB - C interface after the charger is inserted into the USB - C interface. The time constant (τ) of the RC circuit can be calculated by the following formula (1).

[0093] τ = R * C (1)

[0094] Among them, R represents the resistance of the equivalent circuit, C represents the capacitance of the equivalent circuit, and τ characterizes the response speed of the circuit when the input signal changes (that is, after the input signal of the circuit changes, the time required for the circuit to reach a new stable state). When corrosion occurs or the two pins are blocked by foreign objects between them, the values of R and C of the RC equivalent circuit formed between them will change, which will cause a change in the time constant, and further lead to a change in the boost curve between the two pins.

[0095] In addition, according to the characteristics of the RC circuit, when the time approaches infinity, the voltage across the circuit will approach the input voltage. However, in actual situations, due to the internal losses of resistance and capacitance in the circuit, as well as the influence of other factors (such as the specific coverage area and degree of corrosion and foreign objects), the voltage across the RC circuit may not fully reach the input voltage. Therefore, in the scenario where the circuit reaches a stable state within a certain time range, the time it consumes, the generated boost curve, the final voltage value generated across the circuit, and the current value flowing through the circuit may all change due to the degree of interface corrosion and the influence of foreign objects.

[0096] Please refer to Figure 3 , which shows the VBUS boost curves in two abnormal situations (here, the boost curve can be the boost curve relative to any pin, preferably, it can be the boost curve relative to the ground - wire pin, so as to provide a good potential reference point for the VBUS voltage). In abnormal situations, the time required for VBUS to reach the preset voltage and the climbing slope of each voltage - climbing interval may be different from the normal situation. For example, inFigure 3 -a, the voltage change rate in abnormal conditions is greater than that in normal conditions, while in Figure 3 -b, the voltage change rate in abnormal conditions is less than that in normal conditions.

[0097] In the embodiments of the present disclosure, during the change process of the first voltage, the first preset type of feature of the first voltage is collected, and when the difference between the first preset type of feature and the first reference value is greater than the first threshold, it is determined that the interface is in an abnormal state, thereby realizing high-efficiency and high-accuracy interface detection, greatly reducing the difficulty and cost of interface detection, and improving the safety during the use of the interface.

[0098] In some embodiments of the present disclosure, the first preset type of feature characterizes the change rate of the first voltage over time. Its advantage is that it can be closer to the above formula (1), thereby improving the accuracy of interface detection, and can combine experimental data to determine the overall corrosion degree or foreign object blockage degree between pins.

[0099] Specifically, the collecting the first preset type of feature of the first voltage during the change process of the first voltage may include:

[0100] During the change process of the first voltage, in response to the time interval between the current moment and the last time the first voltage was collected reaching the time threshold, the first voltage is collected;

[0101] According to at least two of the first voltages collected and the moments corresponding to the at least two first voltages, the first preset type of feature is determined.

[0102] In addition, the collecting the first preset type of feature of the first voltage during the change process of the first voltage may include:

[0103] According to multiple sets of the first voltages collected, the change rates of the multiple first voltages over time are determined, and the average value of the determined multiple change rates is determined as the first preset type of feature, where each set of the first voltages in the multiple sets of the first voltages includes two first voltages and the moments corresponding to the two voltages.

[0104] In the above embodiments, an interface detection method based on the change rate of the first voltage over time is given. Take Figure 3Taking -a as an example, the rate of change of the first voltage over time during the boost of the first voltage from V1 to V2 can be determined based on the three physical quantities V2, V1, and t1, and this rate of change is matched with a pre - determined standard rate of change during the process of boosting from V1 to V2 (or within the interval from the start time point of t1 to the end time point). If the difference (such as the difference value, or a mathematical quantity obtained based on other algorithms) is greater than the first threshold, it can be considered that the interface is in an abnormal state. In addition, multiple sets of the first voltage (i.e., at least 3 first voltages) can be collected, and based on the average value of the rates of change of the multiple sets of voltages. Preferably, the multiple sets of voltages can have corresponding physical meanings, so as to Figure 3 Taking -a as an example, during the boost process of the first voltage, the first voltage can be collected once every step duration (step size), and based on the rates of change of the voltages at the same time intervals (such as the rates of change corresponding to the time periods t1 and t2, where both t1 and t2 are one step size), the average value of the slopes is calculated, and the obtained average value is matched with the standard value. If the difference is greater than the first threshold, it can be considered that the interface is in an abnormal state.

[0105] Since in an RC circuit, the changes in resistance and capacitance are prominently reflected in the response speed of the circuit when the input signal changes, the above - mentioned embodiments improve the accuracy of the interface detection method by collecting the rate of change of the first voltage or the average value of the rates of change of the first voltage.

[0106] In some embodiments of the present disclosure, the first pin is the power supply pin on the interface, and the second pin is the ground pin on the interface. Since when the interface is connected to the connector, usually one party needs to supply power to the other party based on the power supply pin, and the ground pin is usually connected to the ground body or other potential reference points, when the first pin is the power supply pin on the interface and the second pin is the ground pin on the interface, a more general and stable interface detection process can be provided.

[0107] In some embodiments of the present disclosure, during the change process of the first voltage, collecting the first - preset - type feature of the first voltage includes collecting the first - preset - type feature of the first voltage during the change process of the first voltage being monotonically non - increasing or monotonically non - decreasing. Based on this, the method provided by the present disclosure can avoid collecting data before and after voltage fluctuations when the voltage fluctuates, thus preventing the occurrence of a situation where the accuracy of the data is reduced. It should be understood that if the voltage fluctuates, the fluctuation process can be split into multiple monotonically non - increasing or monotonically non - decreasing change intervals. At this time, reusing the method provided by the present disclosure does not affect the realization of its original technical effects.

[0108] In some embodiments of the present disclosure, the method further includes, in response to the interface being determined to be in an abnormal state, performing at least one of the following operations:

[0109] Present a prompt message for prompting the user that the interface is in an abnormal state;

[0110] Stop the change of the first voltage;

[0111] Disconnect the connection between the interface and the connector to which the interface is connected.

[0112] Among them, the prompt message can be presented based on a visual manner, or based on an audio or other manner. Based on this, after the interface is determined to be abnormal, a response can be made in a timely manner so that the abnormal interface will not damage the device due to reasons such as overheating.

[0113] In some embodiments of the present disclosure, please refer to Figure 4 , the method further includes:

[0114] Step S401, in response to the interface being determined to be in an abnormal state, reverse the change of the first voltage, and collect the second preset type features of the first voltage during the reverse change of the first voltage;

[0115] Step S402, in response to the difference between the second preset type features and the second reference value being less than the second threshold, determine that the interface is in a normal state, where the second reference value represents the value of the second preset type features of the first voltage when the interface is in a normal state.

[0116] In the above embodiments, after the interface is determined to be in an abnormal state, secondary detection can also be performed. Taking the connection between a mobile phone and a charger as an example, after the mobile phone and the charger complete protocol communication, the charger provides a gradually increasing voltage to the mobile phone based on the power supply pin (for example, increasing from 0V to 5V, and this voltage can be determined based on the ground pin). When the difference between the first preset type of feature collected by the device and the first reference value is greater than the first threshold during the process of the voltage increasing from 0V to 5V, the device determines that the interface is in an abnormal state. At this time, the voltage on the power supply pin can be changed in the reverse direction. For example, while stopping the voltage increase, the power supply pin is connected to the ground body (such as the ground pin) through a MOS (Metal-Oxide-Semiconductor Field-Effect Transistor) circuit or a triode circuit, so that the voltage (the first voltage) on the power supply pin drops back to the ground voltage. During this process, the second preset type of feature of the first voltage is collected, and in response to the difference between the second preset type of feature and the second reference value being less than the second threshold, it is determined that the interface is in a normal state (at this time, the aforementioned RC circuit principle also applies). The above judgment process avoids the occurrence of dangerous situations by changing the voltage of the pin on the interface in an abnormal state in the reverse direction, and also provides a secondary detection process, thereby further reducing the false detection rate and improving the accuracy of the method of the present disclosure. For the specific details in the above steps, please refer to the relevant descriptions in the foregoing embodiments and will not be elaborated here.

[0117] In some embodiments of the present disclosure, the method further includes, in response to the interface being determined to be in a normal state, performing at least one of the following:

[0118] Powering the connector connected to the interface;

[0119] Causing the connector connected to the interface to power the interface;

[0120] Performing data communication with the connector connected to the interface.

[0121] Next, through Figure 5 the selection branch diagram shown below, and using the above example, the above at least one embodiment will be described.

[0122] In the first step, in response to detecting the insertion of the charger, before the VUS voltage rises to 5V, calculate the average rising slope (change rate) V2 of VBUS in several step time periods, and calculate whether the absolute value of the difference between V2 and the first reference value V1 is greater than or equal to the first threshold A. If not, the normal charging process can be started until the charging ends or the charger is unplugged.

[0123] Second step, if the absolute value of the difference between V2 and V1 is greater than or equal to the first threshold A, it is determined that the interface is in an abnormal state. At this time, the VBUS voltage can be reversed (for example, connecting VBUS to the ground pin through a MOS transistor), and during the reverse change process, the average decrease slope V2' is determined in several step time intervals, and it is calculated whether the absolute value of the difference between V2' and the second reference value V1' is less than or equal to the second threshold B. If so, the interface can be determined to be normal and the normal charging process can be carried out. If not, the voltage can continue to be reversed (that is, the detection is repeated a preset number of times), or a prompt message can be sent to the user to prompt the user to check the interface status or perform after-sales maintenance.

[0124] For the specific details and related beneficial effects in the above example, please refer to the foregoing embodiments and will not be elaborated herein.

[0125] Corresponding to the embodiments of the foregoing method, the present disclosure also provides embodiments of a device and a terminal to which the device is applied.
