[0045] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details.

Similarly, the phrase "if it is determined" or "if [described condition or event] is detected" can be interpreted as meaning "uponce it is determined" or "in response to determining" or "uponce [described condition or event] is detected" or "in response to detecting [described condition or event]", depending on the context.

[0048] In addition, in the description of the present application specification and the appended claims, the terms "first", "second", "third", etc. are only used to distinguish the descriptions and cannot be understood as indicating or implying relative importance.

[0049] References to "one embodiment" or "some embodiments" etc. described in the specification of this application mean that one or more embodiments of the present application include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, the statements "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0050] In the prior art, when the power supply device and the receiving device are connected via a USB-C cable, the receiving threshold and the sending threshold of the power supply device and the receiving device will not change during the communication process after initialization. When the power transmitted between the power supply device and the receiving device increases, the terrain difference also increases, which may cause the protocol message sent by the power supply device to be unable to be normally received by the receiving device, resulting in poor communication quality.

[0051] Based on the above problems, the communication method provided by the embodiment of the present application first obtains the first current transmitted between the power supply device and the receiving device, and then determines the first target threshold group and the second target threshold group according to the first current. Since the first target threshold group is used to indicate the sending threshold and receiving threshold of the power supply device, and the second target threshold group is used to indicate the sending threshold and receiving threshold of the receiving device. Therefore, the sending threshold and receiving threshold of the power supply device can be adjusted according to the first target threshold group, and the sending threshold and receiving threshold of the receiving device can be adjusted according to the second target threshold group. It can be seen that the embodiment provided by the present application can dynamically adjust the sending threshold and receiving threshold of each of the power supply device and the receiving device according to the size of the first current, thereby effectively adjusting the potential difference. It is ensured that when the power transmitted between the power supply device and the receiving device increases, the receiving device can normally receive the protocol information sent by the power supply device, thereby maintaining the stability and reliability of communication during high-power transmission, and significantly improving the communication quality.

[0052] In order to illustrate the technical solution described in this application, a specific embodiment is provided below for illustration.

[0053] Figure 1 FIG. 1 is a flow chart of a communication method provided by an embodiment of the present application. Figure 1 As shown, the communication method includes steps S101 to S103.

[0054] Step S101: obtaining a first current transmitted between a power supply device and a receiving device.

[0055] Specifically, when the power supply device and the receiving device are connected via the USB-C cable, the power supply device can transmit electrical energy to the receiving device, such as the power supply device can transmit voltage and current to the receiving device. The current (i.e., the first current) on the transmission line between the power supply device and the receiving device can be monitored in real time by a current sensor or other measuring devices and equipment, thereby ensuring the accuracy and reliability of the measuring device to obtain an accurate current value. Finally, the acquired first current is transmitted to a control module (such as a USB PD protocol chip) in the power supply device or the receiving device for subsequent adjustment of the sending threshold and the receiving threshold.

[0056] It should be noted that the acquired first current may be filtered, corrected, etc. again to eliminate noise and errors in the measurement process to ensure the reliability of the first current.

[0057] Step S101 may include step S1011 and step S1012.

[0058] Step S1011, obtaining a first voltage between a first interface and ground, wherein the first interface is an interface connected to a power supply device or an interface connected to a receiving device.

[0059] Specifically, Figure 2 As shown, a first sampling resistor with a first resistance value can be connected in series between the first interface (USB-C port) of the power supply end and the ground (GND). When the first current flows through the first sampling resistor, a voltage drop will be generated on the first sampling resistor. The voltage drop on the first sampling resistor is the first voltage. Figure 3 As shown, a second sampling resistor with a second resistance value can be connected in series between the first interface (USB-C port) of the power receiving end and the ground (GND). When the first current flows through the second sampling resistor, a voltage drop will be generated on the second sampling resistor. The voltage drop on the second sampling resistor is the first voltage. The first resistance value and the second resistance value can be the same or different. Figure 4 As shown, a first sampling resistor can be connected in series between the USB-C port of the power supply end and GND, and a second sampling resistor can be connected in series between the USB-C port of the power receiving end and GND. The use of two sampling resistors can independently measure the current of the power supply end and the power receiving end, avoiding the error that may be introduced by a single sampling resistor in long-distance transmission. At the same time, the two sampling resistors can provide redundant measurement, and the average value of the first sampling voltage generated on the first sampling resistor and the second sampling voltage generated on the second sampling resistor can be used as the above-mentioned first voltage, thereby improving the reliability of the first voltage, and if one of the sampling resistors fails, the other sampling resistor can still work normally, improving the reliability and stability of the system.

[0060] by Figure 4 For example, the three connecting lines between the two USB-C ports are CC channel, power line and ground line from top to bottom. The CC channel is between the USB-C port and the USB PD protocol chip, the CC channel and control communication line are between the USB PD protocol chip at the power supply end and the power access port, and the CC channel and power line are used between the power adapter and the power access port. The power access port and the first power module, the first power module and the first switch unit, the first power module and the USB PD protocol chip at the power supply end, the second power module and the second switch unit, the second power module and the USB PD protocol chip at the power receiving end, the first switch unit and the USB-C port at the power supply end, and the second switch unit and the USB-C port at the power receiving end are all power lines. The first switch unit and the USB PD protocol chip at the power supply end, and the second switch unit and the USB PD protocol chip at the power receiving end are control communication lines. The ground line is between the first sampling resistor and the USB-C port at the power supply end, the first sampling resistor and GND, the second sampling resistor and the USB-C port at the power receiving end, and the second sampling resistor and GND. The sampling communication lines are between the first sampling resistor and the USB PD protocol chip at the power supply end, and between the second sampling resistor and the USB PD protocol chip at the power receiving end.

[0061] It should be noted that a voltage measuring device (such as a voltmeter or a data acquisition system) can also be used to measure the first voltage between the first interface and the ground. At the same time, the obtained first voltage can be filtered, corrected, etc. again to eliminate noise and errors in the measurement process to ensure the reliability of the first voltage.

[0062] Step S1012, calculating the quotient of the first voltage and the resistance value of the sampling resistor to obtain a first current.

[0063] Specifically, since the first voltage has been acquired in step S1011 and the resistance of the sampling resistor is determined, according to Ohm's law, it can be obtained that the first current is equal to the first voltage divided by the resistance of the sampling resistor. The current thus measured has higher accuracy and reliability.

[0064] Step S102: determining a first target threshold group and a second target threshold group according to the first current.

[0065] Specifically, multiple first threshold groups and multiple second threshold groups can be preset according to actual conditions, and the current corresponding to each first threshold group and the current corresponding to each second threshold group can be preset. The USB PD protocol chip in the power supply device will determine one of the multiple first threshold groups that match the first current as the first target threshold group, and the USB PD protocol chip in the receiving device will determine one of the multiple second threshold groups that match the first current as the second target threshold group, thereby ensuring that the power supply device and the receiving device communicate in the best working state.

[0066] It should be noted that the number of the first threshold group and the number of the second threshold group can be the same or different, and the thresholds in the first threshold group and the second threshold group can be the same or different. The larger the first current, the larger the threshold in the first target threshold group, and the smaller the threshold in the second target threshold group.

[0067] Exemplarily, if there are two first threshold groups, namely (0.56V, 1.10V) and (0.68V, 1.15V), there are two second threshold groups, namely (0.56V, 1.10V) and (0.44V, 1.05V). If the first current is 2.95A, the first target threshold group can be determined to be (0.56V, 1.10V), and the second target threshold group can be determined to be (0.56V, 1.10V). If the first current is 3.15A, the first target threshold group can be determined to be (0.68V, 1.15V), and the second target threshold group can be determined to be (0.44V, 1.05V).

[0068] Step S102 may include step S1021 and step S1022.

[0069] Step S1021, determining a target current range according to the first current.

[0070] Specifically, multiple current judgment values ​​are pre-set in the power supply device and the receiving device, and each two adjacent current judgment values ​​constitute a current interval. Among them, the target current interval is an interval in the multiple current intervals that contains the first current. Specifically, after the first current is determined, the first current can be compared with the multiple current intervals. If the first current is greater than or equal to the minimum value in a certain current interval and less than the maximum value of the current interval, the current interval is determined as the target current interval. Among them, the multiple current judgment values ​​set by the power supply device are different from the multiple current judgment values ​​set by the receiving device, and the current interval set by the power supply device is different from the current interval set by the receiving device.

[0071] Exemplarily, if the first current is 2.95A, the power supply device sets four current judgment values, namely: 2.6A, 2.8A, 3.0A and 3.2A. Therefore, there are three current intervals in the power supply device, namely: (2.6-2.8), (2.8-3.0) and (3.0-3.2). The receiving device sets four current judgment values, namely: 2.7A, 2.9A, 3.1A and 3.3A. Therefore, there are three current intervals in the receiving device, namely: (2.7-2.9), (2.9-3.1) and (3.1-3.3). Since the first current is 2.95A, it can be determined that the first current is in the second current interval set by the power supply device, that is, the second current interval set by the power supply device is used as the target current interval of the power supply device. Similarly, the first current is in the second current interval set by the receiving device, that is, the second current interval set by the receiving device is used as the target current interval of the receiving device.

[0072] Step S1022: determining a first target threshold group and a second target threshold group according to the target current range.

[0073] Specifically, the first threshold group corresponding to each current interval in the power supply device and the second threshold group corresponding to each current interval in the receiving device can be pre-set. When the target current interval is determined, the first target threshold group and the second target threshold group can be determined according to the pre-set corresponding relationship. A neural network algorithm or a machine learning model can also be used, using the historical first current data and the corresponding threshold group as training data, and the first target threshold group and the second target threshold group can be determined through the machine learning model.

[0074] It should be noted that, in the case where the current interval includes the first current interval, the second current interval and the third current interval, when the first current is within the first current interval, the first threshold group is determined to be the first target threshold group, and the second threshold group is determined to be the second target threshold group; when the first current is within the second current interval, the third threshold group is determined to be the first target threshold group, and the fourth threshold group is determined to be the second target threshold group; when the first current is within the third current interval, the fifth threshold group is determined to be the first target threshold group, and the sixth threshold group is determined to be the second target threshold group. Specifically, after the first current is determined, the first current is compared with each current interval. If the first current is within the first current interval set by the power supply device and is also within the first current interval set by the receiving device, at this time, the power supply device uses the first threshold group corresponding to the first current interval as the first target threshold group, and the receiving device uses the second threshold group corresponding to the first current interval as the second target threshold group. Similarly, if the first current is within the second current interval, the third threshold group is determined to be the first target threshold group, and the fourth threshold group is determined to be the second target threshold group. The situation is similar to the situation where the first current is within the first current interval, and no further description will be given. The case where the first current is within the third current interval, the fifth threshold group is determined to be the first target threshold group, and the sixth threshold group is determined to be the second target threshold group is similar to the case where the first current is within the first current interval, and will not be repeated herein.

[0075] Exemplarily, there are three current intervals in the power supply device: the first current interval (2.6-2.8), the second current interval (2.8-3.0) and the third current interval (3.0-3.2), and the threshold groups corresponding to the three current intervals are: the first threshold group (0.50V, 1.05V), the third threshold group (0.56V, 1.10V) and the fifth threshold group (0.68V, 1.15V). There are three current intervals in the receiving device: the first current interval (2.7-2.9), the second current interval (2.9-3.1) and the third current interval (3.1-3.3), and the threshold groups corresponding to the three current intervals are: the second threshold group (0.61V, 1.15V), the fourth threshold group (0.56V, 1.10V) and the sixth threshold group (0.44V, 1.05V). If the first current is 2.95A, the first current is in the second current interval in the power supply device and the second current interval in the receiving device. Therefore, the third threshold group (0.56V, 1.10V) is determined as the first target threshold group, and the fourth threshold group (0.56V, 1.10V) is determined as the second target threshold group.

[0076] Step S103: adjusting the sending threshold and receiving threshold of the power supply device according to the first target threshold group, and adjusting the sending threshold and receiving threshold of the receiving device according to the second target threshold group.

[0077] Specifically, each threshold group includes two thresholds, namely a first threshold and a second threshold, wherein the first threshold is greater than the second threshold. After the power supply device determines the first target threshold group according to the magnitude of the first current, the larger first threshold in the first target threshold group is used as the sending threshold of the power supply device, and the smaller second threshold in the first target threshold is used as the receiving threshold of the power supply device. After the receiving device determines the second target threshold group according to the magnitude of the first current, the larger first threshold in the second target threshold group is used as the sending threshold of the receiving device, and the smaller second threshold in the first target threshold is used as the receiving threshold of the receiving device. Thus, the embodiment provided by the present application can dynamically adjust the sending threshold and receiving threshold of each of the power supply device and the receiving device according to the magnitude of the first current, thereby effectively adjusting the potential difference. It is ensured that when the power transmitted between the power supply device and the receiving device increases, the receiving device can normally receive the protocol information sent by the power supply device, thereby maintaining the stability and reliability of communication during high-power transmission, and significantly improving the communication quality.

[0078] In one embodiment of the present application, the communication method further includes steps S104 to S107.

[0079] Step S104: compare the first current with a preset current.

[0080] Specifically, after obtaining the first current, it is necessary to compare the first current with the preset current to determine whether it is necessary to adjust the sending threshold and the receiving threshold. Only when the first current is greater than the preset current will the problem of poor communication quality occur. At this time, the sending threshold and the receiving threshold of the power supply device are adjusted according to the above steps, as well as the sending threshold and the receiving threshold of the receiving device. If the first current is less than the preset current, execute step S105. It can be seen that by comparing the first current with the preset current, the first target threshold and the second target threshold can be determined more accurately, thereby correctly adjusting the sending threshold and the receiving threshold of the power supply device and the receiving device, ensuring that the power supply device and the receiving device communicate in the best working state, and improving the stability and efficiency of the system.

[0081] Step S105: if the first current is less than or equal to the preset current, determining the connection state between the power supply device and the receiving device.

[0082] Specifically, since the first current is less than or equal to the preset current, it may be caused by a poor connection or disconnection. Through this step, it is possible to confirm whether the connection between the power supply device and the receiving device is normal, thereby avoiding misjudgment. If the connection is poor or disconnected, the current may be lower than the preset value. By confirming the connection status, such physical connection problems can be ruled out, ensuring that subsequent threshold adjustments and system operations are based on the correct connection status, ensuring the accuracy of threshold adjustment. In addition, if a poor connection or disconnection is found when confirming the connection status, it can be repaired in time to avoid further fault diagnosis and processing. This helps to quickly restore the normal operation of the system.

[0083] Step S106, if the first current is less than or equal to the preset current and the power supply device and the receiving device are disconnected, the sending threshold of the power supply device is set to the first sending threshold, the receiving threshold of the power supply device is set to the first receiving threshold, the sending threshold of the receiving device is set to the second sending threshold, and the receiving threshold of the receiving device is set to the second receiving threshold.

[0084] Specifically, the first sending threshold and the first receiving threshold are the initial threshold group of the power supply device, and the second sending threshold and the second receiving threshold are the initial threshold group of the receiving device. When the first current is less than or equal to the preset current and the power supply device and the receiving device are disconnected, the sending threshold and the receiving threshold of the power supply device do not need to be adjusted, and they are still the thresholds in the initial threshold group of the power supply device, and the sending threshold and the receiving threshold of the receiving device do not need to be adjusted, and they are still the thresholds in the initial threshold group of the receiving device. This design can avoid unnecessary threshold adjustment operations and reduce the complexity of system management. In addition, maintaining the initial threshold can ensure that the system behaves consistently when disconnected, avoiding unpredictable behavior caused by threshold changes. This helps the system return to normal more easily when the connection is restored.

[0085] Step S107: If the first current is less than or equal to the preset current, and the power supply device is connected to the receiving device, execute step S104.

[0086] Specifically, when the first current is less than or equal to the preset current, and it is determined that the power supply device and the receiving device are in a connected state, at this time, the first current and the preset current are repeatedly compared. In this process, if the first current is always less than the preset current, the sending threshold and the receiving threshold of the power supply device and the receiving device do not need to be adjusted, and the thresholds in the initial threshold group are still maintained. Only when the first current is greater than the preset current are the above steps S102 to S103 executed. Therefore, by continuously monitoring the first current and the connection status between the power supply device and the receiving device, it can be ensured that the system can respond in a timely manner, avoid misjudgment due to threshold adjustment, and improve the reliability of the system.

[0087] It should be noted that the workflow diagram of the communication method provided in the embodiment of the present application is as follows Figure 5 As shown, Figure 5 In the figure, SRC is the power supply end (Source), SNK is the power receiving end (Sink), ADC is the analog-to-digital converter (Analog-to-Digital Converter), A1, A2 and A3 are three current judgment values, R1, R2, R3 and R4 are all receiving thresholds, T1, T2, T3 and T4 are all sending thresholds, R1 and T1 are a threshold group, R2 and T2 are a threshold group, R3 and T3 are a threshold group, and R4 and T4 are a threshold group. The specific process is explained as follows: First, SRC (SNK) is powered on and initialized, and the USB PD chip initializes the receiving threshold and sending threshold to R1 and T1. At this time, SRC (SNK) and SNK (SRC) establish a connection, and the USB PD chip detects the first current transmitted through ADC. Then the current value of the first current is compared with A1, A2 and A3 to determine the corresponding sending threshold and receiving threshold. Specifically, when the current value is less than or equal to A1, determine whether SRC (SNK) and SNK (SRC) are disconnected. If disconnected, execute the step of initializing the receiving threshold and sending threshold to R1 and T1 of the USB PD chip; if not disconnected, continue to determine the size of the current value and A1 until the current value is greater than A1. Next, continue to determine whether the current value is less than or equal to A2. If the current value is greater than A1 and less than or equal to A2, the USB PD chip sets the receiving threshold and sending threshold to R2 and T2. If the current value is greater than A2, then continue to determine whether the current value is less than or equal to A3. If the current value is greater than A2 and less than or equal to A3, the USB PD chip sets the receiving threshold and sending threshold to R3 and T3. If the current value is greater than A3, the USB PD chip sets the receiving threshold and sending threshold to R4 and T4.

[0088] In one embodiment of the present application, the communication method further includes steps S108 to S109.

[0089] Step S108: monitoring the communication quality parameters between the power supply device and the receiving device.

[0090] Specifically, communication quality parameters generally include signal strength, bit error rate, signal delay, etc. This application can ensure that the communication between the devices is stable and reliable by monitoring the communication quality parameters between the power supply device and the receiving device in real time. This helps to promptly discover and deal with potential communication problems and avoid data transmission errors or interruptions caused by poor communication quality.

[0091] Step S109: when it is detected that the communication quality parameter is less than a preset value, the sending threshold and the receiving threshold of the power supply device are increased, and the sending threshold and the receiving threshold of the receiving device are decreased.

[0092] Specifically, the preset value is used to determine whether the communication quality is within an acceptable range. Setting the preset value helps the system take measures before the communication quality drops to an unacceptable level. This can prevent the communication quality from further deteriorating and ensure that the system operates in a normal state. When the communication quality parameter is less than the preset value, it indicates that the communication quality is gradually decreasing. At this time, the sending threshold and receiving threshold of the power supply device are increased, and the sending threshold and receiving threshold of the receiving device are reduced at the same time, thereby effectively adjusting the potential difference. It ensures that when the power transmitted between the power supply device and the receiving device increases, the receiving device can normally receive the protocol information sent by the power supply device, thereby maintaining the stability and reliability of communication during high-power transmission, and significantly improving the communication quality.

[0093] In one embodiment of the present application, the communication method further includes step S110 to step S111.

[0094] Step S110, obtaining a correspondence between the first current and the first target threshold group, and a correspondence between the first current and the second target threshold group.

[0095] Specifically, the correspondence between the first current and the first target threshold value group and the second target threshold value group can be determined by experiments or predefined rules. For example, the first threshold value group and the second threshold value group under different current values ​​can be measured by experiments, so as to determine the first target threshold value group and the second target threshold value group according to the detected first current. Alternatively, the correspondence relationship can be defined according to the requirements of system design, which can be in the form of mathematical functions, tables or mapping tables.

[0096] Step S111 : associating and storing the first current with the first target threshold group, and associating and storing the first current with the second target threshold group.

[0097] Specifically, after the correspondence between the first current and the first target threshold group is obtained, the first current and the first target threshold group are associated and stored so that they can be quickly searched and applied in subsequent use. Similarly, after the correspondence between the first current and the second target threshold group is obtained, the first current and the second target threshold group are associated and stored so that they can be quickly searched and applied in subsequent use.

[0098] It should be noted that association and storage can be implemented in a variety of ways. It can be stored in a database, and the corresponding relationship can be obtained by querying the database to determine the first target threshold group and the second target threshold group. It can also be stored in a mapping table, using a dictionary or a hash table to store the corresponding relationship between the first current and the first target threshold group and the second target threshold group, so as to quickly search.

[0099] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
