[0008] In combination with the first aspect, in some embodiments, multiple device functions include: audio input and output functions; the first electronic device detects multiple device functions of the second electronic device based on the first communication connection, specifically including: the first electronic device simulates the audio signal received by the USB interface, and transmits the audio signal to the second electronic device through the USB interface of the second electronic device; the second electronic device records the audio signal and returns the recorded audio signal to the first electronic device; the first electronic device compares whether the recorded audio signal is consistent with the audio signal received by the USB interface simulated by the first electronic device, and if so, the audio input and output functions are normal.

The first electronic device can compare whether the audio signal recorded by the second electronic device is consistent with the audio signal received by the USB interface simulated by the first electronic device, thereby automatically identifying whether the second electronic device has an audio input and output function failure. There is no need for testers to subjectively judge whether the audio signal is normal, nor is there a need for testers to manually identify audio input and output function failures, thereby improving the accuracy and efficiency of the test.

[0011] In combination with the first aspect, in some embodiments, multiple device functions include: an OTG device insertion direction identification function; the first electronic device detects multiple device functions of the second electronic device based on the first communication connection, specifically including: the first electronic device outputs an OTG device insertion signal that can be detected by the USB interface; the second electronic device outputs an OTG device insertion direction identification result based on the OTG device insertion signal, and returns the OTG device insertion direction identification result to the first electronic device; the first electronic device compares the OTG device insertion direction identification result and the OTG device insertion signal to see if they match, and if so, the OTG device insertion direction identification function is normal.

In this case, the OTG device insertion direction identification result can be Figure 2 The OTG reverse signal detection result is shown.

[0013] In this way, the first electronic device can perform OTG device insertion direction identification function detection on the second electronic device based on the first communication connection. The first electronic device can compare whether the OTG device insertion signal output by the first electronic device and the OTG device insertion direction identification result output by the second electronic device based on the OTG device insertion signal are consistent, thereby automatically identifying whether the second electronic device has an OTG device insertion direction identification function failure, thereby improving the efficiency of the test.

[0014] In combination with the first aspect, in some embodiments, the first electronic device outputs an OTG device insertion signal that can be detected by the USB interface, specifically including: the first electronic device simulates the OTG device insertion signal that can be detected by the USB interface, and transmits the OTG device insertion signal to the second electronic device through the USB interface of the second electronic device.

[0015] In this way, the first electronic device can simulate an OTG device insertion signal that can be detected by the USB interface and transmit the OTG device insertion signal to the second electronic device for subsequent OTG device insertion direction identification function detection. There is no need to manually generate an OTG device insertion signal by inserting an OTG device, which simplifies the operation and is convenient and quick.

[0016] In combination with the first aspect, in some embodiments, the first electronic device includes an OTG interface, an OTG device is inserted into the OTG interface, and the first electronic device outputs an OTG device insertion signal that can be detected by the USB interface, specifically including: the first electronic device inserts the OTG device into the OTG interface, and the OTG device insertion signal generated is transmitted to the second electronic device through the USB interface of the second electronic device.

[0017] In this way, the first electronic device can transmit the OTG device insertion signal generated when the OTG device is inserted into the OTG interface to the second electronic device, so as to be used for subsequent OTG device insertion direction identification function detection.

[0018] In combination with the first aspect, in some embodiments, the OTG device insertion signal output by the first electronic device is an OTG device forward insertion signal, and the OTG device insertion direction identification result consistent with the OTG device forward insertion signal includes indication information that the insertion direction of the OTG device is forward; or, the OTG device insertion signal output by the first electronic device is an OTG device reverse insertion signal, and the OTG device insertion direction identification result consistent with the OTG device reverse insertion signal includes indication information that the insertion direction of the OTG device is reverse.

[0019] In this way, the OTG device insertion signal can be matched with the OTG device insertion direction identification result according to whether the OTG device insertion signal is a forward insertion signal or a reverse insertion signal, thereby determining whether the OTG device insertion direction identification function of the second electronic device is normal.

[0020] In combination with the first aspect, in some embodiments, multiple device functions include: a charging type identification function; the first electronic device detects multiple device functions of the second electronic device based on the first communication connection, specifically including: the first electronic device outputs a power supply signal that can be detected by the USB interface; the second electronic device outputs a charging type identification result based on the power supply signal, and returns the charging type identification result to the first electronic device; the first electronic device compares whether the charging type identification result and the power supply signal are consistent, and if so, the charging type identification function is normal.

[0021] The power supply signal that the USB interface can detect may include but is not limited to Figure 2 The high voltage charging detection signal, low voltage charging detection signal, and PD charging detection signal shown, the above charging type identification results may include but are not limited to Figure 2 The high-voltage charging signal detection results, low-voltage charging signal detection results, and PD charging signal detection results are shown.

[0022] In this way, the first electronic device can perform charging type identification function detection on the second electronic device based on the first communication connection. The first electronic device can compare whether the power supply signal output by the first electronic device and the charging type identification result output by the second electronic device based on the power supply signal are consistent, thereby automatically identifying whether there is a charging type identification function failure in the second electronic device, thereby improving the efficiency of the test.

[0023] In combination with the first aspect, in some embodiments, the first electronic device outputs a power supply signal that can be detected by the USB interface, specifically including: the first electronic device simulates the power supply signal that can be detected by the USB interface, and transmits the power supply signal to the second electronic device through the USB interface of the second electronic device.

[0024] In this way, the first electronic device can simulate a power supply signal that can be detected by the USB interface and transmit the power supply signal to the second electronic device for subsequent charging type identification function detection. There is no need to manually generate a power supply signal by plugging in a power source, which simplifies the operation and makes it convenient and quick.

[0025] In combination with the first aspect, in some embodiments, the first electronic device includes a power interface, the power interface is connected to a power source, and the first electronic device outputs a power signal that can be detected by the USB interface, specifically including: the first electronic device inserts the power source into the power interface, and the power signal generated is transmitted to the second electronic device through the USB interface of the second electronic device.

[0026] In this way, the first electronic device can transmit the power supply signal generated by the power supply being inserted into the power interface to the second electronic device, so as to be used for subsequent charging type identification function detection.

[0027] In combination with the first aspect, in some embodiments, the power supply signal output by the first electronic device is a high-voltage power supply signal, and the charging type identification result consistent with the high-voltage power supply signal is: the charging type is high-voltage fast charging; or, the power supply signal output by the first electronic device is a low-voltage power supply signal, and the charging type identification result consistent with the low-voltage power supply signal is: the charging type is low-voltage fast charging.

[0028] In this way, the power supply signal can be matched with the charging type identification result according to the type of the power supply signal, so as to determine whether the charging type identification function of the second electronic device is normal.

[0029] In combination with the first aspect, in some embodiments, the method also includes: the first electronic device also establishes a second communication connection with the third electronic device through the USB interface of the third electronic device; the first electronic device detects multiple device functions of the third electronic device based on the second communication connection, and the multiple device functions of the third electronic device are device functions provided by the third electronic device based on the USB interface of the third electronic device; wherein, after one device function of the third electronic device is detected, another device function is started to be detected; the condition for starting to detect another device function provided by the third electronic device is that the detection of one device function is completed.

[0030] The third electronic device may be a tested device (eg, a mobile phone) other than the second electronic device, and the tested device may establish another communication connection (eg, the second communication connection) with the first electronic device.

[0031] In this way, the first electronic device (ie, the testing device) can support parallel device function testing of multiple devices under test (eg, the second electronic device, the third electronic device, etc.), thereby improving the testing efficiency.

[0032] In combination with the first aspect, in some embodiments, the method further includes: when the first electronic device detects the first device function of the second electronic device based on the first communication connection, the first electronic device detects the second device function of the third electronic device based on the second communication connection.

[0033] Among them, the first device function may be an audio input and output function / OTG device insertion direction identification function / charging type identification function, and the second device function may be a function other than the first device function.

[0034] In some embodiments, when there are multiple detection items corresponding to the first device function, the second electronic device and the third electronic device can also perform the first device function detection at the same time, but the detection items need to be different, so as to avoid the conflict of detection items of two different tested devices. For example, assuming that the first device function is an audio input and output function, the audio input and output function includes two detection items: analog headphone signal detection and digital headphone signal detection. Then, when the analog headphone signal detection is performed on the second electronic device, the digital headphone signal detection can be performed on the third electronic device.

[0035] In this way, after the first electronic device completes the detection of the first device function on the second electronic device, the first electronic device can detect the first device function on the third electronic device and detect the second device function on the second electronic device, and so on.

[0036] In combination with the first aspect, in some embodiments, the method also includes: the first electronic device sends a first message to the second electronic device, the first message is used to indicate that the detection of a device function is completed; the second electronic device sends a second message to the first electronic device, the second message is used to indicate that the second electronic device has entered a state where detection of another device function has begun.

[0037] Among them, the first message can be a message sent by the first electronic device to the second electronic device after completing a device function test (or when each device function includes multiple test items, each time a test item is completed), and the second message can be a message sent by the second electronic device to the first electronic device after receiving the above-mentioned first message.

[0038] In this way, each time the detection of one function is completed, the first electronic device can automatically proceed to the detection of the next function without the need for the tester to manually switch the detection items, thereby simplifying the operation, saving labor costs, shortening the time of the entire detection process, and improving detection efficiency.

[0039] In combination with the first aspect, in some embodiments, another device function is an audio input and output function, and the method also includes: the first electronic device sends a first detection instruction to the second electronic device, and the first detection instruction is used to trigger the second electronic device to enter an audio recording state; the first electronic device receives a third message sent by the second electronic device, and the third message is used to indicate that the second electronic device has entered an audio recording state.

[0040] The first detection instruction may be Figure 2 The analog headset signal detection instruction shown, in this case, the third message can be Figure 2 Message 2 shown; or, the first detection instruction may be Figure 2 The digital headphone signal detection instruction shown, the third message may be message 4.

[0041] In this way, when the first electronic device starts to detect the audio input and output function, it sends a first detection instruction to the second electronic device. If the second electronic device enters the audio recording state, the second electronic device can send a third message to the first electronic device so that the first electronic device can start to detect the audio input and output function of the second electronic device after knowing that the second electronic device enters the audio recording state.

[0042] In combination with the first aspect, in some embodiments, another device function is an OTG device insertion direction identification function, and the method also includes: the first electronic device sends a second detection instruction to the second electronic device, and the second detection instruction is used to trigger the second electronic device to enter the OTG device insertion direction identification state; the first electronic device receives a fourth message sent by the second electronic device, and the fourth message is used to indicate that the second electronic device has entered the OTG device insertion direction identification state.

[0043] The second detection instruction may be Figure 2 The OTG positive signal detection instruction shown, in this case, the fourth message can be Figure 2 Message 6 shown; or, the second detection instruction may be Figure 2 The OTG reverse signal detection instruction shown, in this case, the fourth message can be Figure 2 Message 7 is shown.

[0044] In this way, when the first electronic device starts to detect the OTG device insertion direction identification function, it sends a second detection instruction to the second electronic device. If the second electronic device enters the OTG device insertion direction identification state, the second electronic device can send a fourth message to the first electronic device, so that the first electronic device can start to detect the OTG device insertion direction identification function of the second electronic device after knowing that the second electronic device enters the OTG device insertion direction identification state.

[0045] In combination with the first aspect, in some embodiments, another device function is a charging type identification function, and the method also includes: the first electronic device sends a third detection instruction to the second electronic device, and the third detection instruction is used to trigger the second electronic device to enter a charging type identification state; the first electronic device receives a fifth message sent by the second electronic device, and the fifth message is used to indicate that the second electronic device has entered a charging type identification state.

[0046] The third detection instruction may be Figure 2 The high voltage charging signal detection instruction shown, in this case, the fifth message can be Figure 2 Message 8 shown; or, the third detection instruction may be Figure 2 The low voltage charging signal detection instruction shown, in this case, the fifth message can be Figure 2 Message 9 shown; or, the third detection instruction may be Figure 2 In this case, the fifth message may be Figure 2 Message 10 is shown.

[0047] In this way, when the first electronic device starts to detect the charging type identification function, it sends a third detection instruction to the second electronic device. If the second electronic device enters the charging type identification state, the second electronic device can send a fifth message to the first electronic device so that the first electronic device can start to detect the charging type identification function of the second electronic device after knowing that the second electronic device enters the charging type identification state.

[0048] In combination with the first aspect, in some embodiments, before the first electronic device detects multiple device functions of the second electronic device based on the first communication connection, the method also includes: the first electronic device sends a detected state feedback instruction to the second electronic device; the first electronic device receives a sixth message sent by the second electronic device, and the sixth message is used to indicate that the second electronic device has entered the detected state.

[0049] Among them, the sixth message can be Figure 2 Message 1 is shown.

[0050] In this way, after the first electronic device establishes the first communication connection with the second electronic device, if the first electronic device is already in place (i.e., enters the normal detection state), the first electronic device can send a detected state feedback instruction to the second electronic device. After the second electronic device receives the instruction, if the second electronic device has entered the detected state, the second electronic device can send a sixth message to the first electronic device, so that the first electronic device can start to perform device function detection on the second electronic device after learning that the second electronic device has entered the detected state.

[0051] In combination with the first aspect, in some embodiments, the USB interface is a Type-C interface.

[0052] In a second aspect, the present application provides an electronic device, comprising one or more processors and one or more memories; wherein the one or more memories are coupled to the one or more processors, and the one or more memories are used to store computer program code, and the computer program code includes computer instructions, and when the one or more processors execute the computer instructions, the electronic device executes any method described in the first aspect above.

[0064] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in the text is only a description of the association relationship of the associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0065] It should be understood that the terms "first", "second", etc. in the specification, claims and drawings of the present application are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices.

[0066] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0067] Before electronic devices are put on the market, device manufacturers usually conduct device function tests on each electronic device, for example, the man-machine interface (MMI) function test related to the universal serial bus (USB) interface of the electronic device. Among them, the USB interface can include Type-A interface, Type-B interface, and Type-C interface. Taking the Type-C interface as an example, at present, the MMI function test related to the Type-C interface of electronic devices (such as mobile phones) usually includes analog headphone signal detection, digital headphone signal detection, OTG (on-the-go) positive and negative function detection, high-voltage DC fast charging function detection, low-voltage DC fast charging function detection, and power delivery (PD) fast charging function detection.

[0068] However, currently, the above functions are usually tested manually. Figure 1A , Figure 1A A test device (also referred to as a detection device) provided in an embodiment of the present application is exemplarily shown, and the test device needs to perform device function detection on the device under test (also referred to as the device under test) by manual detection. The test device may include multiple interfaces (e.g., interface 110, interface 111, interface 112, interface 113, interface 114, interface 115, interface 116, interface 117, interface 118), multiple buttons (e.g., button 119, button 120, button 121, button 122, button 123, button 124, button 125, button 126, button 127). Among them, the six interfaces from interface 110 to interface 115 can be connected to headphones and chargers, and can be used for headphone signal detection and charging signal detection, interface 116 and interface 117 can be connected to data storage devices (e.g., USB flash drives, etc.), and can be used for OTG signal detection, and interface 118 can be connected to the device under test (e.g., mobile phones, etc.). Among them, the above-mentioned multiple buttons can be used to start / stop corresponding detection items (such as headphone signal detection, charging signal detection, OTG signal detection and other detection items) and control the switch of the test equipment.

[0069] Taking the above-mentioned MMI function detection related to the Type-C interface of the electronic device as an example, at present, the entire test operation process of using the above-mentioned test equipment to perform device function detection on the device under test is usually as follows: First, the tester needs to place the device under test (such as a mobile phone) under the test equipment, and use the Type-C data cable to connect the test equipment to the device under test. After the connection is completed, the tester can start the device function detection. Exemplarily, the tester can click the analog signal headset detection button, and then manually press the headset line control position pause button, manually record the voice, and after the voice is recorded, it is necessary to press the headset line control position pause button again, play the recorded voice, listen to whether the played sound is consistent with the recorded sound, and judge whether there are noises and other problems. Exemplarily, the tester can also click the digital signal headset detection button, and then manually press the headset line control position pause button, manually record the voice, and after the voice is recorded, it is necessary to press the headset line control position pause button again, play the recorded voice, listen to whether the played sound is consistent with the recorded sound, and judge whether there are noises and other problems. Exemplarily, the tester can also click the high-voltage DC fast charge detection button, and after observing that the test is passed on the device under test, the next test can be performed. Exemplarily, the tester can also click the low-voltage DC fast charge detection button, and after observing that the test is passed on the device under test, the next test can be performed. Exemplarily, the tester can also click the PD fast charge detection button, and after observing that the test is passed on the device under test, the next test can be performed. Exemplarily, the tester can also click the OTG front detection button, and after observing that the test is passed on the device under test, the next test can be performed. Exemplarily, the tester can also click the OTG back detection button, and after observing that the test is passed on the device under test, the next test can be performed. The test ends when all detection items are completed.

[0070] It can be seen that the entire test process described above has the following shortcomings: 1. Testers need to manually switch test items, and need to manually input and play voice when performing headphone signal detection. The operation is cumbersome and it takes a long time to perform a complete test. 2. The test equipment can usually only detect one device at a time and does not support functional testing of multiple tested devices in parallel, resulting in low detection efficiency. 3. Testers need to manually judge the strength of the voice signal when performing headphone signal detection. This subjective performance detection method easily leads to low accuracy of the test results.

[0071] Based on the above problems, an embodiment of the present application provides a device function detection method, in which the test device can establish a communication connection with the device being tested. Based on the communication connection, the test device can perform multiple function detections on the device being tested in sequence (for example, analog headphone signal detection, digital headphone signal detection, OTG positive and negative function detection, high-voltage DC fast charging function detection, low-voltage DC fast charging function detection, PD fast charging function detection, etc.). After completing the detection of each function, the test device can automatically proceed to the detection of the next function without the need for the tester to manually switch the detection items, thereby simplifying the operation, saving labor costs, and shortening the time of the entire detection process. In addition, the test device can also support functional detection of multiple devices being tested in parallel, thereby improving detection efficiency.

[0072] A communication system provided by an embodiment of the present application is introduced below.

[0073] Figure 1B A communication system provided by an embodiment of the present application is exemplified.

[0074] like Figure 1B As shown, the communication system may include: an electronic device 100 (testing device), and one or more electronic devices 200 (tested devices).

[0075] Among them, the electronic device 100 (also known as a detection device) can be used to perform device function detection on one or more electronic devices 200 (also known as detected devices), such as analog headphone signal detection, digital headphone signal detection, OTG positive and negative function detection, high-voltage DC fast charging function detection, low-voltage DC fast charging function detection, PD fast charging function detection, etc.

[0076] Different from the above Figure 1A The test equipment shown in the figure performs a function test on the device under test by manual detection. Figure 1B The electronic device 100 shown can automatically perform device function detection on the device under test without the need for the tester to manually switch the detection items. In addition, it can also support functional detection of multiple devices under test in parallel.

[0077] The electronic device 200 may be any type of intelligent terminal device, and the embodiment of the present application does not limit the specific type of the electronic device 200. For example, the electronic device 200 may be a mobile phone, a tablet computer, a desktop computer, a laptop computer, a handheld computer, a notebook computer, etc. The embodiment of the present application does not limit the number of the electronic devices 200.

[0078] In the embodiment of the present application, the device function detection method provided by the present application is described by taking the electronic device 200 as a terminal device with a Type-C interface as an example, which should not constitute a limitation on the present application. In some other embodiments of the present application, the electronic device 200 may also be a terminal device with other types of interfaces.

[0079] In an embodiment of the present application, before the electronic device 100 performs a device function detection on the electronic device 200, a communication connection can be established between the electronic device 100 and the electronic device 200, and based on the communication connection, the electronic device 100 can perform a device function detection on the electronic device 200. Among them, the communication connection established between the electronic device 100 and the electronic device 200 may include but is not limited to: a wired connection (for example, a wired connection established by a data cable connected via a Type-C interface), a wireless connection such as a Bluetooth (BT) connection and a wireless fidelity (WiFi) connection, etc. In addition, the electronic device 100 and the electronic device 200 in the communication system can also be connected and communicated in combination with any of the above-mentioned methods, and the embodiment of the present application does not limit this. That is to say, the electronic device 100 and the electronic device 200 in the communication system can form a network (i.e., networking) according to a certain communication protocol and networking strategy, so that the electronic device 100 and the electronic device 200 can communicate with each other.

[0080] Figure 2 The specific process of a device function detection method provided in an embodiment of the present application is exemplified.

[0081] like Figure 2 As shown, the method can be applied to a communication system including an electronic device 100 (i.e., a test device) and an electronic device 200 (i.e., a device under test). In the embodiment of the present application, the electronic device 200 is a terminal device (e.g., a mobile phone) having a Type-C interface. The specific steps of the method may include: Figure 2 The specific steps of the method are described in detail below:

[0082] Phase 1: Initialization phase

[0083] S201 : The electronic device 100 establishes a communication connection with the electronic device 200 .

[0084] Specifically, before the device function detection, the electronic device 100 can be initialized, and a communication connection can be established between the electronic device 100 and the electronic device 200. In this way, the electronic device 100 and the electronic device 200 can exchange data based on the communication connection during the device function detection process (for example, in the subsequent steps, during the analog headphone signal detection stage, the electronic device 100 sends an audio playback instruction 1 to the electronic device 200, and the electronic device 200 sends an audio signal 1 to the electronic device 100; etc.).

[0085] The communication connection may be a communication connection established between the electronic device 100 and the electronic device 200 by wired connection and / or wireless connection. The wired connection may be, for example, a wired connection established by a data cable connected via a Type-C interface, and the wireless connection may be, for example, one or more of a Bluetooth connection and a WiFi connection.

[0086] S202-S203, the electronic device 100 sends a detected state feedback instruction to the electronic device 200, and then the electronic device 200 sends a message 1 to the electronic device 100, where the message is used to instruct the electronic device 200 to enter a normal detected state.

[0087] Specifically, after the electronic device 100 establishes a communication connection with the electronic device 200, since the electronic device 100 can establish a communication connection with multiple electronic devices 200 at the same time so that device function detection can be performed on multiple electronic devices 200 in parallel, before executing the above step S202, the method also includes: the electronic device 100 obtains and identifies the port information of each electronic device 200 based on the above communication connection, and numbers each electronic device 200 in turn for easy distinction.

[0088] After the electronic device 100 establishes a communication connection with the electronic device 200, if the electronic device 100 is already in place (i.e., has entered a normal detection state), then the electronic device 100 can send a detection state feedback instruction to the electronic device 200, which can be used to notify the electronic device 200 that the electronic device 100 is in place, and can also be used to instruct the electronic device 200 to send relevant information to the electronic device 100 regarding whether the electronic device 200 has entered a normal detection state.

[0089] In some embodiments, the above step S202 is optional.

[0090] After the electronic device 100 establishes a communication connection with the electronic device 200, if the electronic device 200 enters a normal detected state (also referred to as an initial state), the electronic device 200 may send a message 1 to the electronic device 100, which may be used to indicate that the electronic device 200 enters a normal detected state, so that the electronic device 100 may start performing device function detection on the electronic device 200 after knowing that the electronic device 200 enters a normal detected state.

[0091] In some embodiments, if the electronic device 200 has not entered the normal detected state, the electronic device 200 may also send a message to the electronic device 100 indicating that the electronic device 200 has not entered the normal detected state, so that the electronic device 100 can promptly know the status of the electronic device 200 and determine whether it can start device function detection on the electronic device 200.

[0092] In some embodiments, the above step S203 is optional.

[0093] In some embodiments, before executing the above step S203, the method also includes: after the electronic device 100 establishes a communication connection with the electronic device 200, the electronic device 200 can determine whether it has entered a normal detected state (that is, whether it meets the initial state). If not, the electronic device 200 can display relevant prompt information (also known as error information) to prompt the tester that the electronic device 200 has not entered a normal detected state, so that the tester can correct the state of the electronic device 200 in time.

[0094] In some embodiments, after the state of the electronic device 200 is corrected by the tester, the electronic device 200 can re-establish the communication connection with the electronic device 100. For example, the tester can re-plug and unplug the data cable connected to the Type-C interface of the electronic device 200 to re-establish the communication connection.

[0095] After completing the above-mentioned stage 1, the electronic device 100 can start to perform device function detection on the electronic device 200. Among them, the detection items of the device function detection may include one or more items. In the case of multiple detection items, the detection time sequence of the detection items may be default or manually set in advance. The embodiment of the present application does not limit the detection time sequence of the detection items.

[0096] In the embodiment of the present application, taking the electronic device 100 performing multiple detection items on the electronic device 200 as an example, these multiple detection items may include but are not limited to: analog headphone signal detection, digital headphone signal detection, OTG front signal detection, OTG back signal detection, high-voltage charging signal detection, low-voltage charging signal detection, and PD charging signal detection.

[0097] It is easy to understand that the detection time sequence of the above multiple detection items can be arbitrary. Figure 2 The detection time sequence shown is for illustration only and should not be construed as limiting the present application.

[0098] It is easy to understand that the embodiments of the present application are only Figure 2 The multiple detection items shown in the figure are used as examples for illustration. In some embodiments, the number of detection items may be greater than Figure 2 The number of test items shown may be fewer or greater.

[0112] Specifically, after receiving the audio signal 1 sent by the electronic device 200, the electronic device 100 can determine whether the voice simulation signal is consistent with the audio signal 1. If so, it means that the electronic device 200 passes the analog headphone signal detection, and the function of the electronic device 200 to record and output the analog headphone signal is normal.

After the electronic device 100 receives the OTG reverse side signal detection result sent by the electronic device 200, it can determine whether the OTG reverse side signal detection result is passed. If so, it means that the OTG reverse side function of the electronic device 200 is normal. Further, the electronic device 100 can execute the steps in the next stage; if not, it means that the OTG reverse side function of the electronic device 200 is abnormal. Further, the electronic device 100 can record the detection result 4, and the detection result 4 can include information used to indicate that the electronic device 200 did not pass the OTG reverse side signal detection. Further, after the detection result 4 is recorded, the electronic device 100 can execute the steps in the next stage.

[0158] In some embodiments, the OTG reverse signal detection instruction in the above step S228 may include information about the OTG reverse signal detection detection item (such as the name of the OTG reverse signal detection detection item and other information). Before executing the above step S230, the method also includes: the electronic device 200 sends information to the electronic device 100 to indicate whether the information about the OTG reverse signal detection detection item is correct. If correct, the electronic device 100 can continue to execute subsequent steps. If incorrect, the electronic device 100 can re-send the OTG reverse signal detection instruction to the electronic device 200.

[0159] In some embodiments, when the electronic device 200 passes the OTG reverse signal detection, the electronic device 100 may also record the detection result, which may include information indicating that the electronic device 200 passes the OTG reverse signal detection.

[0160] In some embodiments, the electronic device 100 may also directly save the OTG reverse signal detection result sent by the electronic device 200. In this case, the electronic device 100 may not execute the above steps S232 to S233.

[0161] In some embodiments, stage five described above is optional.

[0162] In some embodiments, after executing all the steps of the above-mentioned OTG reverse signal detection phase, the electronic device 100 may also send a message to the electronic device 200 indicating that the OTG reverse signal detection is completed, so as to carry out the detection of the next detection item. After receiving the above-mentioned message, the electronic device 200 may also send a message to the electronic device 100 indicating that it has entered the state of the next detection item to be detected.

[0163] The OTG function mentioned in the embodiment of the present application is an extended function of wireless communication devices and mobile devices, which can be used to connect different electronic devices to each other, exchange data, etc.

[0164] In some embodiments, the OTG front detection signal and the OTG back detection signal sent by the aforementioned electronic device 100 to the electronic device 200 may both refer to OTG device insertion signals, wherein the OTG front detection signal is the OTG device forward insertion signal, and the OTG back detection signal is the OTG device reverse insertion signal. The USB interface of the electronic device 200 may include a CC1 pin and a CC2 pin, wherein CC1 and CC2 may be two pins constituting a configuration channel (Configuration Channel, CC) of the electronic device 200. After the electronic device 200 detects the OTG device insertion signal sent by the aforementioned electronic device 100, the CC1 pin and the CC2 pin of the electronic device 200 may output different voltage values, and the OTG forward and reverse function detection may be performed by comparing these two different voltage values.

[0165] In one possible implementation, if the voltage value of the CC1 pin of the electronic device 200 is higher than the voltage value of the CC2 pin, it means that the electronic device 200 determines that the OTG device is inserted from the front (i.e., the insertion direction of the OTG device is forward); if the voltage value of the CC1 pin of the electronic device 200 is lower than the voltage value of the CC2 pin, it means that the electronic device 200 determines that the OTG device is inserted from the back (i.e., the insertion direction of the OTG device is reverse).

[0166] In another possible implementation, if the voltage value of the CC1 pin of the electronic device 200 is lower than the voltage value of the CC2 pin, it means that the electronic device 200 determines that the OTG device is inserted from the front (that is, the insertion direction of the OTG device is forward); if the voltage value of the CC1 pin of the electronic device 200 is higher than the voltage value of the CC2 pin, it means that the electronic device 200 determines that the OTG device is inserted from the back (that is, the insertion direction of the OTG device is reverse).

[0167] In some embodiments, the OTG front signal detection result or OTG back signal detection result sent by the aforementioned electronic device 200 to the electronic device 100 may include but is not limited to the following information: indication information on whether the OTG device has been inserted, and indication information on whether the OTG device is inserted frontally or backside.

[0168] It can be seen that the device functions of the electronic device 200 detected in the above-mentioned stage four (OTG front signal detection stage) and stage five (OTG back signal detection stage) are the OTG front function and the OTG back function, wherein the OTG front function and the OTG back function can also be referred to as the OTG device insertion direction identification function. The aforementioned electronic device 100 determines whether the OTG front signal detection result / OTG back signal detection result is passed, specifically, it can be: the electronic device 100 compares whether the OTG device insertion direction identification result and the OTG device insertion signal are consistent. If so, it means that the OTG device insertion direction identification function of the electronic device 200 is normal. It is easy to understand that if the OTG device insertion direction identification result is the aforementioned OTG front signal detection result, then the OTG device insertion signal is the aforementioned OTG front detection signal, and if the OTG device insertion direction identification result is the aforementioned OTG back signal detection result, then the OTG device insertion signal is the aforementioned OTG back detection signal.

[0169] Among them, the OTG device insertion direction identification result is consistent with the OTG device insertion signal, specifically: when the OTG device insertion signal is a forward insertion signal of the OTG device, the OTG device insertion direction identification result may include indication information that the insertion direction of the OTG device is forward; when the OTG device insertion signal is a reverse insertion signal of the OTG device, the OTG device insertion direction identification result may include indication information that the insertion direction of the OTG device is reverse.

If correct, the electronic device 100 can continue to execute subsequent steps. If incorrect, the electronic device 100 can re-send the high-voltage charging signal detection instruction to the electronic device 200.

Further, the electronic device 200 can send the high-voltage charging signal detection result to the electronic device 100. After the electronic device 100 receives the high-voltage charging signal detection result sent by the electronic device 200, it can determine whether the high-voltage charging signal detection result is passed. If so, it means that the high-voltage charging identification function of the electronic device 200 is normal and can support high-voltage charging. Further, the electronic device 100 can execute the steps in the next stage; if not, it means that the high-voltage charging identification function of the electronic device 200 is abnormal. Further, the electronic device 100 can record the detection result 5, and the detection result 5 may include information used to indicate that the electronic device 200 did not pass the high-voltage charging signal detection.

[0203] S248-S251, the electronic device 100 sends a PD charging detection signal to the electronic device 200, and then the electronic device 200 sends a PD charging signal detection result to the electronic device 100. After that, the electronic device 100 determines whether the PD charging signal detection result passes, and if so, executes the steps in the next stage, and if not, records the detection result 7, and after recording is completed, executes the steps in the next stage.

[0204] Among them, after receiving the PD charging detection signal sent by the electronic device 100, the electronic device 200 can automatically perform PD charging signal detection based on the PD charging detection signal. After the detection is completed, a PD charging signal detection result can be generated, and the PD charging signal detection result can include information used to indicate whether the electronic device 200 passes the PD charging signal detection.

After receiving the above message, the electronic device 200 may also send a message to the electronic device 100 that it has entered the state of the next detection item to be detected.

[0215] In some embodiments, after each test item is completed, the electronic device 200 can display relevant information indicating whether the test item has passed, so that the tester can know whether the test item has passed in a timely manner.

[0216] In some embodiments, after completing the PD charging signal detection on the electronic device 200, if the electronic device 100 has completed all the detection items on the electronic device 200, the electronic device 200 may display relevant information indicating that all the detection items have been completed / ended, so that the tester can promptly know whether the electronic device 100 has completed the device function detection work on the electronic device 200.

[0217] In an embodiment of the present application, the electronic device 100 can support parallel device function detection of multiple electronic devices 200. For example, after the electronic device 100 completes the detection of the first detection item on the first electronic device 200, the electronic device 100 can then perform the detection of the first detection item on the second electronic device 200, and at the same time perform the detection of the second detection item on the first electronic device 200. After the electronic device 100 completes the detection of the first detection item on the second electronic device 200 and completes the detection of the second detection item on the first electronic device 200, the electronic device 100 can then perform the detection of the first detection item on the third electronic device 200, and at the same time perform the detection of the second detection item on the second electronic device 200, and perform the detection of the third detection item on the first electronic device 100, and so on. For example, after the electronic device 100 completes the above-mentioned analog headphone signal detection on the first electronic device 200, the electronic device 100 can then perform the analog headphone signal detection on the second electronic device 200, and at the same time perform the digital headphone signal detection on the first electronic device 200.

The various components shown in the figure may be implemented in hardware, software, or a combination of hardware and software including one or more signal processing and / or application specific integrated circuits.

[0252] The following is a schematic diagram of the principle of an analog headphone signal detection circuit provided in an embodiment of the present application.

[0255] Among them, the storage module 401 can be connected to the micro control unit 402, the micro control unit 402 can be connected to the digital-to-analog conversion module 403 and the digital-to-analog conversion module 407, the digital-to-analog conversion module 403 can be connected to the power amplifier module 404, the power amplifier module 404 can be connected to the switch module 405, the switch module 405 can be connected to the voltage detection module 406, and the voltage detection module 406 can be connected to the digital-to-analog conversion module 407.

[0256] The switch module 405 may be, for example, the aforementioned Figure 3 The switch module 301 is shown.

[0257] The process of analog headphone signal detection is exemplarily described below in conjunction with the above analog headphone signal detection circuit.

[0258] First, the storage module 401 can store an audio file, the microcontroller unit 402 can read the audio file, and generate a voice digital signal based on the audio file. Further, the microcontroller unit 402 can convert the voice digital signal into a voice analog signal through the digital-to-analog conversion module 403, and can send the voice analog signal to the switch module 405 after power amplification through the power amplifier module 404. Further, the switch module 405 can send the voice analog signal after power amplification to the device under test (for example, the electronic device 200). Further, the device under test can record the voice analog signal to generate an audio signal (for example, the aforementioned Figure 2The audio signal 1 shown in the figure can be sent to the switch module 405. Further, the switch module 405 can send the audio signal to the voltage detection module 406. Further, the voltage detection module 406 can compare the voltage value of the audio signal (for example, the effective value of the voltage of the audio signal) with a preset voltage value (also referred to as a normal voltage value, that is, the voltage value corresponding to the audio signal when the analog headphone signal recording function and the output function of the tested device are normal). If the voltage value of the audio signal is lower than the preset voltage value, it indicates that the test has not passed and the tested device may have a fault, for example, the impedance may increase due to port corrosion; for example, the internal circuit of the tested device may be open circuited; and so on. Furthermore, in the case that the above-mentioned audio signal is a digital signal, the voltage detection module 406 can also convert the above-mentioned audio signal into an analog signal through the digital-to-analog conversion module 407, and send the analog signal to the microcontroller unit 402. Further, the microcontroller unit 402 can determine whether the frequency of the analog signal is consistent with the frequency of the above-mentioned voice analog signal sent to the device under test.

Further, the switch module 504 can send the voice digital signal after power amplification to the device under test (for example, the electronic device 200). Further, the device under test can record the voice digital signal to generate an audio signal (for example, the aforementioned Figure 2The audio signal 2 shown in the figure can be sent to the switch module 504. Further, the switch module 504 can send the audio signal to the voltage detection module 505. Further, the voltage detection module 505 can compare the voltage value of the audio signal (for example, the effective value of the voltage of the audio signal) with a preset voltage value (also referred to as a normal voltage value, that is, the voltage value corresponding to the audio signal when the digital headphone signal recording function and the output function of the tested device are normal). If the voltage value of the audio signal is lower than the preset voltage value, it indicates that the test has not passed and the tested device may have a fault, for example, the impedance may increase due to port corrosion; for example, there may be a short circuit in the internal circuit of the tested device; and so on. Furthermore, the voltage detection module 505 can also send the audio signal to the micro control unit 502. Further, the micro control unit 502 can determine whether the audio signal is consistent with the voice digital signal sent to the device under test.

[0291] The external memory interface 220 can be used to connect an external memory card, such as a Micro SD card, to expand the storage capacity of the electronic device 200. The external memory card communicates with the processor 210 through the external memory interface 220 to implement a data storage function, such as storing music, video and other files in the external memory card.
