With the improvement of people's environmental awareness, more users currently tend to sell their idle electronic products in the recycling market (i.e., the second-hand market).

[0003] For recycled electronic products, various function detections need to be carried out. In particular, the charging function of electronic products will greatly affect the use of electronic products by users. The existing detection solutions mainly rely on manual operation. After the tester connects the electronic product to the power supply, the charging function is judged according to the phenomena displayed by the device, and the detection result is easily affected subjectively and is inaccurate.

[0024] In order to more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the following will briefly introduce the drawings required for use in the description of the embodiments or the prior art. Obviously, the drawings in the following description are only the embodiments of this application. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on the provided drawings.

[0025] Figure 1 FIG. 1 is one of the schematic diagrams of a charging function detection system provided by an embodiment of this application;

[0026] Figure 2 FIG. 2 is another schematic diagram of a charging function detection system provided by an embodiment of this application. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the drawings in the embodiments of this application. Obviously, the described embodiments are some, but not all, of the embodiments of this application. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of this application.

[0028] Since the charging function of electronic products greatly affects the user experience, it is necessary to detect the charging function of recycled electronic products.

[0029] Existing detection solutions mainly rely on manual operation. After the testing personnel connect the electronic product to the power supply, they judge the charging function based on the phenomena shown by the device. For example, if the electronic product shows that it is in the charging state and the battery level increases after a period of time (such as 5 minutes), the testing personnel consider that the charging function of the electronic product is normal. However, there may be other problems with the charging function, such as the charging voltage being less than the normal value, poor contact of the charging port, and other problems that affect the charging function. These problems are difficult to detect manually.

[0030] It can be seen that the detection results obtained based on the existing charging function detection method are easily affected by subjectivity and are inaccurate.

[0031] To solve the foregoing problems, the embodiments of the present application provide a charging function detection system. Through this detection system, the charging function can be automatically detected, so that the detection results are not affected by human subjective judgment, thereby improving the accuracy of the detection results.

[0032] The following describes the charging function detection system in detail through some embodiments. The following several embodiments can be combined with each other, and the same or similar concepts or processes may not be described in some embodiments.

[0033] As Figure 1 shown, the charging function detection system may include: a data acquisition device 101 and a detection device 102. A data acquisition circuit 1011 is provided in the data acquisition device 101, and a detection circuit 1021 is provided in the detection device 102. Communication can be performed between the data acquisition circuit 1011 and the detection circuit 1021.

[0034] The data acquisition circuit 1011 may include a first interface and a second interface. The first interface is used to connect the device to be detected 102. The data acquisition circuit 1011 is configured to provide a power signal to the device to be detected 102 through the first interface and receive a charging signal generated by the device to be detected 103 in response to the power signal. The second interface is used to connect the detection circuit 1021.

[0035] The detection circuit 1021 is configured to receive the charging signal through the second interface and output a detection signal based on the charging signal and a reference signal. The detection signal is used to characterize the detection result of the charging function of the device to be detected 103. For example, it can be used to characterize whether the charging function of the device to be detected 103 is normal.

[0036] The charging signal described in the embodiments of the present application may include, but is not limited to, at least one of the following: charging voltage, charging current. The reference signal may be a normal charging signal. By comparing the charging signal with the reference signal, it can be determined whether the charging function of the device to be detected 103 is normal.

[0037] Optionally, the reference signal can be the minimum value of the normal charging signal, such as the minimum value of the normal charging voltage or the minimum value of the normal charging current. Suppose the charging signal includes the charging voltage and the charging current. If the charging voltage of the device 103 to be detected obtained during the detection process is greater than or equal to the minimum value of the normal charging voltage of the device 103 to be detected, and the charging current of the device 103 to be detected obtained during the detection process is greater than or equal to the minimum value of the normal charging current of the device 103 to be detected, then it can be determined that the charging function of the device 103 to be detected is normal; conversely, if the charging voltage of the device 103 to be detected obtained during the detection process is less than the minimum value of the normal charging voltage of the device 103 to be detected, or the charging current of the device 103 to be detected obtained during the detection process is less than the minimum value of the normal charging current of the device 103 to be detected, then it can be determined that the charging function of the device 103 to be detected is abnormal.

[0038] Optionally, the reference signal can include the maximum and minimum values of the normal charging signal, such as the minimum and maximum values of the normal charging voltage, and the minimum and maximum values of the normal charging current. Suppose the charging signal includes the charging voltage and the charging current. If the charging voltage of the device 103 to be detected obtained during the detection process is greater than or equal to the minimum value of the normal charging voltage of the device 103 to be detected and less than or equal to the maximum value of the normal charging voltage of the device 103 to be detected, and the charging current of the device 103 to be detected obtained during the detection process is greater than or equal to the minimum value of the normal charging current of the device 103 to be detected and less than or equal to the maximum value of the normal charging current of the device 103 to be detected, then it can be determined that the charging function of the device 103 to be detected is normal; conversely, if the charging voltage of the device 103 to be detected obtained during the detection process is less than the minimum value of the normal charging voltage of the device 103 to be detected, or the charging voltage of the device 103 to be detected obtained during the detection process is greater than the maximum value of the normal charging voltage of the device 103 to be detected, or the charging current of the device 103 to be detected obtained during the detection process is less than the minimum value of the normal charging current of the device 103 to be detected, or the charging current of the device 103 to be detected obtained during the detection process is greater than the maximum value of the normal charging current of the device 103 to be detected, then it can be determined that the charging function of the device 103 to be detected is abnormal.

[0039] Among them, the detection signal can be a high-low level signal. For example, it can be set that a high-level signal indicates normal charging function and a low-level signal indicates abnormal charging function. It can be understood that it can also be set that a low-level signal indicates normal charging function and a high-level signal indicates abnormal charging function, which can be specifically set according to actual requirements.

[0040] As can be seen from the foregoing, the technical solution provided by the embodiments of the present application is to perform a charging function detection by a machine device based on the charging signal of the device to be detected 103, rather than for a tester to judge the charging function according to the phenomena shown by the device. Performing the charging function detection by a machine device can make the detection result not affected by subjective human judgment, thereby improving the accuracy of the detection result. In addition, when performing the charging function detection by a machine device, after obtaining the charging signal, it can quickly judge whether the charging function is normal, without waiting for a long time to observe whether the battery level increases, so that the detection duration can be reduced from the original several minutes (such as 5 minutes) to several seconds (such as 30 seconds), and the detection efficiency is relatively high.

[0041] In some alternative embodiments, many current electronic products support the fast charging function. Without a prompt during charging, it is also difficult for a tester to judge whether the electronic device to be detected supports the fast charging function. However, in the embodiments of the present application, the detection circuit 1021 can also output a detection signal for characterizing whether the device to be detected 103 supports the fast charging function based on the charging signal and the reference signal, so as to realize the detection of whether the fast charging function is supported. In this case, the reference signal can be the normal charging signal of the device to be detected 103 in the fast charging mode.

[0042] For example, some fast charging technologies are achieved by increasing the charging voltage. Therefore, the charging signal described in the embodiments of the present application may include: the charging voltage. The reference signal may include the normal charging voltage corresponding to the fast charging function of the device to be detected 103. By comparing the charging voltage of the device to be detected 103 obtained during the detection process with the normal charging voltage corresponding to the fast charging function of the device to be detected 103, it can be determined whether the device to be detected 103 supports the fast charging function.

[0043] Optionally, the reference signal may be the minimum value of the normal charging signal corresponding to the fast charging function of the device to be detected 103, such as the minimum value of the normal charging voltage corresponding to the fast charging function. Assume that the charging signal includes the charging voltage. If the charging voltage of the device to be detected 103 obtained during the detection process is greater than or equal to the minimum value of the normal charging voltage corresponding to the fast charging function of the device to be detected 103, it can be determined that the device to be detected 103 supports the fast charging function; conversely, if the charging voltage of the device to be detected 103 obtained during the detection process is less than the minimum value of the normal charging voltage corresponding to the fast charging function of the device to be detected 103, it can be determined that the device to be detected 103 does not support the fast charging function.

[0044] Optionally, the reference signal may include the maximum and minimum values of the normal charging signal corresponding to the fast charging function of the device 103 to be detected, such as the minimum and maximum values of the normal charging voltage corresponding to the fast charging function. Assume that the charging signal includes the charging voltage. If the charging voltage of the device 103 to be detected obtained during the detection process is greater than or equal to the minimum value of the normal charging voltage corresponding to the fast charging function of the device 103 to be detected and less than or equal to the maximum value of the normal charging voltage corresponding to the fast charging function, it can be determined that the device 103 to be detected supports the fast charging function; conversely, if the charging voltage of the device 103 to be detected obtained during the detection process is less than the minimum value of the normal charging voltage corresponding to the fast charging function of the device 103 to be detected, or the charging voltage of the device 103 to be detected obtained during the detection process is greater than the maximum value of the normal charging voltage corresponding to the fast charging function of the device 103 to be detected, it can be determined that the device 103 to be detected does not support the charging function.

[0045] It can be understood that the detection method for whether the device 103 to be detected supports the fast charging mode is not limited to the foregoing method, and other charging signals can also be combined for detection, such as combining the charging current for detection. Correspondingly, the reference signal can also include the normal charging current corresponding to the fast charging function of the device 103 to be detected, which can improve the accuracy of the detection result. Among them, the specific judgment method for determining whether the device 103 to be detected supports the fast charging function based on the charging voltage and charging current is similar to the judgment method for determining whether the charging function of the device 103 to be detected is normal based on the charging voltage and charging current, and will not be elaborated here.

[0046] Among them, if the detection signal is a high-low level signal, the high level signal can be set to indicate support for the fast charging function, and the low level signal can be set to indicate non-support for the fast charging function. It can be understood that the low level signal can also be set to indicate normal charging function, and the high level signal can be set to indicate abnormal charging function, which can be specifically set according to actual needs.

[0047] In some alternative embodiments, as Figure 2 shown, the data acquisition circuit 1011 may include a power supply module 10111 and a sampling circuit 10112.

[0048] The power supply module 10111 is configured to provide a power signal to the device 103 to be detected through the first interface, and the sampling circuit 10112 is configured to collect the charging signal generated by the device 103 to be detected in response to the power signal.

[0049] Optionally, since the power signals required by different devices 103 to be detected may be different, the power supply module 10111 can be a power supply module with adjustable power signals to meet the charging requirements of different devices 103 to be detected.

[0050] For example, the power supply module 10111 can be a power supply module with multi-channel output, that is, the power supply module 10111 has multiple independent output channels, and each channel can output different power signals. By selecting different output channels, different power signals can be output. For another example, the power supply module 10111 can also be an adjustable voltage regulator, and the output voltage can be changed by adjusting the voltage on its control pin, thereby changing the power signal. For still another example, the power supply module 10111 can also be a power supply module that controls the output of different power signals through a software program.

[0051] It can be understood that the number of the power supply modules 10111 can also be multiple, and different power signals output by different power supply modules 10111 are used to meet the charging requirements of different devices to be detected 103.

[0052] In some alternative embodiments, when detecting whether the charging function of the device to be detected 103 is normal, in addition to determining whether the charging voltage and charging current are normal when the device to be detected 103 is charging based on the charging signal and the reference signal, it is also possible to determine whether there is a problem of poor contact at the charging port of the device to be detected 103 based on the continuity of the charging signal.

[0053] If the charging signal is continuous, that is, there is no charging disconnection, it is considered that there is no problem of poor contact; on the contrary, if there is a disconnection in the charging signal, it is considered that there is a problem of poor contact.

[0054] In some alternative embodiments, the data acquisition circuit 1011 can include multiple first interfaces. Through these multiple first interfaces, multiple devices to be detected 103 can be connected simultaneously to implement the detection of the charging functions of multiple devices to be detected 103 at the same time, improving the detection efficiency.

[0055] Optionally, since the power signals required by different devices to be detected 103 may be different, different power signals can be configured to be output by different first interfaces to meet the charging requirements of different devices to be detected 103. In this case, a power supply module 10111 with adjustable power signal can be set to connect different first interfaces so that different first interfaces output different power signals; different first interfaces can also be set to connect different power supply modules 10111 so that different first interfaces output different power signals.

[0056] Optionally, the same first interface may also output different power signals. Since the power signals required by the same device under test 103 may be different in different charging modes. For example, the voltage signal in the slow charging mode is generally smaller than that in the fast charging mode. Therefore, the power signal of the same first interface can also be configured to be adjustable to meet the charging requirements of the same device under test 103 in different charging modes. In this case, the same first interface can be connected to a power module 10111 with an adjustable power signal to make the same first interface output different power signals; alternatively, the same first interface can be connected to different power modules 10111, and multiple power modules 10111 can work in a switched manner to make the same first interface output different power signals at different times.

[0057] Optionally, the data acquisition device 101 may be a hub, the data acquisition circuit 1011 is a circuit structure in the hub, and the first interface in the data acquisition circuit 1011 is a hub port on the hub. Using the hub port as a power supply port and connecting it to the device under test 103 can implement the charging function detection of multiple devices under test 103 at the same time, improving the detection efficiency.

[0058] Optionally, the data acquisition circuit 1011 and the device under test 103 can be connected by a charging cable. One end of the charging cable is provided with a plug matching the charging port of the device under test 103, such as a Micro USB plug, a Lightning plug, or a USB Type-C plug, etc., and the other end of the charging cable is provided with a plug matching the first interface of the data acquisition device 101, such as a USB Type-A plug, etc.

[0059] In some alternative embodiments, as Figure 2 shown, the detection circuit 1021 may include a comparison module 10211.

[0060] The comparison module 10211 may include a first input terminal, a second input terminal, a comparison unit, and an output terminal.

[0061] Among them, the first input terminal is used to input a charging signal; the second input terminal is used to input a reference signal; the comparison unit is used to compare the magnitude relationship between the charging signal and the reference signal to generate a detection signal; the output terminal is used to output the detection signal.

[0062] Optionally, the comparison module 10211 may include at least one comparator. The number of comparators may be set based on the number of signals included in the reference signal. For example, in the case where the reference signal includes one signal, such as including one reference charging voltage (e.g., the minimum value of the normal charging voltage), one comparator may be set. The first input terminal of this comparator may input the charging voltage of the device 103 to be detected during the detection process, the second input terminal of this comparator may input the reference charging voltage, and the signal output from its output terminal is the detection signal.

[0063] In the case where the reference signal includes two signals, such as including one reference charging voltage (e.g., the minimum value of the normal charging voltage) and a reference charging current (e.g., the minimum value of the normal charging current), or including two reference charging voltages (the minimum and maximum values of the normal charging voltage), two comparators (hereinafter referred to as the first comparator and the second comparator) may be set. The following takes the case where the reference signal includes the minimum and maximum values of the normal charging voltage, the detection signal is a high and low level signal, and the low level signal indicates that the charging function is normal and the high level signal indicates that the charging function is abnormal as an example for illustration.

[0064] The first input terminal of the first comparator may input the charging voltage of the device 103 to be detected during the detection process, its second input terminal may input the minimum value of the normal charging voltage, and the input signals are compared through the comparison circuit in the first comparator, that is, the charging voltage is compared with the minimum value of the normal charging voltage, and the first comparison signal is output from the output terminal of the first comparator. Among them, the first comparison signal being high level indicates that the detected charging voltage is normal compared with the minimum value of the normal charging voltage, and the second comparison signal being low level indicates that the detected charging voltage is abnormal compared with the minimum value of the normal charging voltage.

[0065] The first input terminal of the second comparator may input the charging voltage of the device 103 to be detected during the detection process, its second input terminal may input the maximum value of the normal charging voltage, and the input signals are compared through the comparison circuit in the second comparator, that is, the charging voltage is compared with the maximum value of the normal charging voltage, and the first comparison signal is output from the output terminal of the second comparator. Among them, the second comparison signal being high level indicates that the detected charging voltage is normal compared with the maximum value of the normal charging voltage, and the second comparison signal being low level indicates that the detected charging voltage is abnormal compared with the maximum value of the normal charging voltage.

[0066] In this embodiment, the comparison module 10211 may further include a NAND gate circuit. The input signals of the input terminals of the NAND gate circuit are the first comparison signal and the second comparison signal respectively, and the output signal of its output terminal is the detection signal.

[0067] When both the first comparison signal and the second comparison signal are at a high level, that is, when the detected charging voltage is normal compared to the maximum and minimum values of the normal charging voltage, the output terminal of the NAND gate circuit outputs a low level, indicating that the charging function is normal.

[0068] When any one of the first comparison signal and the second comparison signal is at a low level, that is, when the detected charging voltage is abnormal compared to the maximum value of the normal charging voltage, and / or when the detected charging voltage is abnormal compared to the minimum value of the normal charging voltage, the output terminal of the NAND gate circuit outputs a high level, indicating that the charging function is abnormal.

[0069] In this example, the first input terminals of the first comparator and the second comparator are equivalent to the first input terminal of the comparison module 10211; the second input terminals of the first comparator and the second comparator are equivalent to the second input terminal of the comparison module 10211, and the output terminal of the NAND gate circuit is equivalent to the output terminal of the comparison module 10211; other circuit structures are equivalent to the comparison unit of the comparison module 10211.

[0070] When the reference signal includes four signals, four comparators can be set, and the comparison module 10211 can also include a NAND gate circuit. The specific output manner of the detection signal is similar to the previous example and will not be elaborated here.

[0071] Optionally, the detection device 102 can also perform a charging function detection based on the charging signal through a software program.

[0072] For example, through a software program, compare the charging voltage obtained during the detection process with the normal voltage range corresponding to the device 103 to be detected, and compare the charging current obtained during the detection process with the normal current range corresponding to the device 103 to be detected to determine whether the charging function of the device 103 to be detected is normal. If the charging voltage is within the normal voltage range and the charging current is within the normal current range, it can be considered that the charging function of the device 103 to be detected is normal. Conversely, if any of the above is not satisfied, it can be considered that the charging function of the device 103 to be detected is abnormal. It can be understood that the detection method for whether the charging function is normal is not limited to the foregoing method and can also be implemented by other methods.

[0073] For another example, through a software program, compare the charging voltage obtained during the detection process with the normal voltage range corresponding to the fast charging function of the device 103 to be detected to determine whether the device 103 to be detected supports the fast charging function. If the charging voltage obtained during the detection process is within the normal voltage range corresponding to the fast charging function of the device 103 to be detected, it can be considered that the device 103 to be detected supports the fast charging function; conversely, it can be considered that the device 103 to be detected does not support the fast charging function.

[0074] In some alternative embodiments, the charging function detection system may further include: a conveyor belt. The conveyor belt is used to convey the device to be detected 103 to the detection area, eliminating manual transportation and improving the detection efficiency.

[0075] In some alternative embodiments, the charging function detection system may further include: a robotic arm. The robotic arm is configured to grab the device to be detected 103 from the conveyor belt and place the device to be detected 103 in the detection area, eliminating manual handling and improving the detection efficiency.

[0076] In some alternative embodiments, the charging function detection system may further include: a device shelf located in the detection area. The device shelf is used to place the device to be detected 103, making the placement of the device to be detected 103 neat and orderly, facilitating the orderly detection of the device to be detected 103. The device that has completed the charging function detection can be removed from the device shelf to make room for a new device to be detected 103.

[0077] Optionally, the robotic arm can also be used to grab the device to be detected 103 from the conveyor belt and place the device to be detected 103 on the device shelf.

[0078] Optionally, the device shelf may include multiple shelf positions, so as to place multiple devices to be detected 103 simultaneously, enabling the simultaneous detection of multiple devices to be detected 103 and improving the detection efficiency.

[0079] Optionally, an indicator light is provided at each shelf position. The indicator light is configured to indicate the detection status, so as to know the detection status of each device to be detected 103. The detection status described here may include, but is not limited to, at least one of the following: to-be-detected status, detecting status, and detection-ended status.

[0080] Optionally, the indicator light can indicate different detection statuses in different colors. For example, when the device to be detected 103 is placed on the device shelf and has not entered the charging state, the indicator light can be displayed in yellow, indicating the to-be-detected status; when the device to be detected 103 is connected to the data acquisition device 101 and enters the charging state, the indicator light can be displayed in green, indicating the detecting status; when the device to be detected 103 has entered the charging state for a preset duration or is disconnected from the data acquisition device 101, the indicator light can be displayed in red, indicating the detection ended.

[0081] Optionally, different detection states can be indicated by an indicator light in different colors, or by multiple indicator lights in different colors. Specifically, it can be set according to actual requirements. It can be understood that different detection states can also be indicated by other states of the indicator light. For example, different detection states can be indicated by the extinguished state, the constantly lit state, and the flashing state of the indicator light. For example, the extinguished state represents the state to be detected, the constantly lit state represents the state of being detected, and the flashing state represents the state of detection end.

[0082] Optionally, the indicator light can be controlled by a switch or by software.

[0083] In the case of software control, the indicator light can be connected to the detection device 102. When the detection device 102 detects a new device 103 to be detected, it assigns an idle target shelf position to the new device 103 to be detected, and controls the indicator light at the target shelf position to light up in a first color, indicating the state to be detected. When the data acquisition device 101 is connected to the device 103 to be detected, the data acquisition device 101 can send a first piece of information to the detection device 102 to inform the detection device 102 that the device 103 to be detected enters the charging state. The detection device 102 controls the indicator light at the target shelf position to light up in a second color according to the first signal, indicating the state of being detected. After the device 103 to be detected enters the charging state for a preset duration or is disconnected from the data acquisition device 101, it controls the indicator light at the target shelf position to light up in a third color, indicating the end state of detection.

[0084] Optionally, when the robotic arm can also be used to grab the device 103 to be detected from the conveyor belt and place the device 103 to be detected on the device shelf, the robotic arm can specifically be used to determine the target shelf position based on the color or state of the indicator light, and place the device 103 to be detected at the target shelf position. Optionally, the robotic arm can also pick up the device 103 to be detected from the target shelf position and place the device 103 to be detected on the conveyor belt for the next detection step. Specifically, the target shelf position can be determined based on the color or state of the indicator light, and the device 103 to be detected can be picked up from the target shelf position.

[0085] Optionally, a two-dimensional code can be displayed on the screen of the device 103 to be detected, and the two-dimensional code can be associated with the quality inspection code and IMEI code of the device 103 to be detected. The robotic arm can also be used to scan the two-dimensional code to obtain information such as the quality inspection code and IMEI code of the device 103 to be detected, and send it to the detection device 102 as a second piece of information, so that the detection device 102 can detect the arrival of the new device 103 to be detected.

[0086] In some alternative embodiments, the detection device 102 may send the output detection results to the cloud server for generating a self-check report of the device 103 to be detected.

[0087] For recycled electronic devices, not only the charging function needs to be detected, but also other functions such as the camera function and the display function need to be detected, and a self-check report is generated based on the detection results of each function. When the detection items of the same detection device 102 do not cover all detection items, the detection results of multiple detection devices 102 for different detection items can be uploaded to the cloud server, and the cloud server combines the detection results of each detection item to generate a self-check report.
