[0029] The technical solutions in the embodiments of the present application will be clearly described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application belong to the scope of protection of the present application.

[0030] The terms "first", "second", etc. in the specification of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order different from those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same category, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the specification means at least one of the connected objects, and the character " / " generally represents an "or" relationship between the associated objects before and after.

[0031] The terms used in the embodiments of the present application will be described below first, as specifically shown below:

[0032] UFCS: Universal fast charging specification, a fusion fast charging technical specification;

[0033] Vconn: The power supply pin inside the Type-c port;

[0034] A-to-C cable: Standard-A to Type-c cable, where A represents the A port and C represents the C port.

[0035] As described above, the data cable has the functions of charging and data transmission, that is, it can both charge the device and realize data transmission between different devices. Taking the data cable including an A-to-C cable as an example, the A-to-C cable is a Universal Serial Bus (USB) cable, one end of which is a USB-A interface and the other end is a USB-C interface, also called a Type-C port. Such a cable is usually used to connect devices supporting the USB-A interface such as traditional chargers, laptop computers, etc. to devices supporting the USB-C interface such as smart phones, game controllers, etc.

[0036] Currently, the A-to-C cable mainly cooperates with the Universal fast charging specification (UFCS) protocol to achieve charging and data transmission. To cooperate with the UFCS protocol, a cable electronic tag needs to be added to the A-to-C cable. Through the cable electronic tag, cable information of the A-to-C cable can be obtained, such as the maximum current that the A-to-C cable can withstand, to ensure the safety and efficiency of charging. When obtaining the cable information of the A-to-C cable through the cable electronic tag, the cable electronic tag needs to be powered on, that is, power needs to be supplied to the cable electronic tag.

[0037] The related technology mainly uses the voltage bus (VBUS) at the power supply end of the A-to-C cable to supply power to the cable electronic tag. The operating voltage of the cable electronic tag is generally between 3.3V - 5.5V, and the supply voltage of VBUS is between 5V - 20V. To meet the voltage requirements of the cable electronic tag, an additional voltage stabilizing device needs to be added to reduce the voltage of VBUS to 3.3V - 5.5V through the voltage stabilizing device, which will increase the hardware cost. Moreover, VBUS supplies power to the cable electronic tag continuously, which is likely to cause energy consumption loss.

[0038] Therefore, the embodiments of the present application provide a power supply method, device, equipment, and storage medium for a cable electronic tag, which can reduce the power supply cost of the cable electronic tag and the energy consumption loss caused by power supply.

[0039] The following will combine the accompanying drawings to describe in detail the power supply method for the cable electronic tag provided by the embodiments of the present application through specific embodiments and their application scenarios.

[0040] Figure 1 FIG. is a schematic diagram of an application scenario of a power supply method for a cable electronic tag provided by an embodiment of the present application. As Figure 1 shown, the application scenario may include a first electronic device 101, a second electronic device 102, and a data cable 103. The first electronic device 101 and the second electronic device 102 are communicatively connected through the data cable 103. Exemplarily, the first electronic device may be a device supporting a Type-A interface, such as but not limited to a charger, a power adapter, a computer, etc. The second electronic device may be a device supporting a Type-C interface, such as but not limited to a mobile phone, a tablet computer, a game controller, etc.

[0041] The data cable 103 can be a cable that supports both Type-A and Type-C interfaces. For example, in some embodiments, the data cable 103 can be an A-to-C cable. That is, the first electronic device 101 can charge the second electronic device via the A-to-C cable, or the first electronic device 101 can transfer data with the second electronic device 102 via the A-to-C cable. That is, the first electronic device 101 can send data to the second electronic device 102 via the A-to-C cable, and the first electronic device 101 can also receive data sent by the second electronic device 102 via the A-to-C cable.

[0042] Taking the data cable 103 including an A-to-C cable as an example, Figure 2 Exemplarily, a schematic diagram of an A-to-C cable is provided. The A-to-C cable includes two ports, namely the A port 201 and the C port 202. Among them, the C port 202 includes 24 pin feet, and the A port includes 4 pin feet. The structure of the 24 pin feet of the C port 202 is as Figure 3 shown.

[0043] The A-to-C cable includes a cable electronic tag. Through the cable electronic tag, the first electronic device 101 and the second electronic device 102 can obtain the cable information of the A-to-C cable. The cable information can include, for example, but is not limited to, the maximum current that the A-to-C cable can withstand, the temperature of the A-to-C cable, the over-temperature and over-voltage protection mechanisms of the A-to-C cable, etc.

[0044] Figure 4 Exemplarily, an internal structure schematic diagram of an A-to-C cable is provided, as Figure 4 shown. The C port 202 includes a power supply pin VBUS, a power supply pin Vconn, a ground pin GND, a data transmission pin D+, and a data transmission pin D-. The other pins are not shown in Figure 4 and can be specifically referred to in Figure 3 . The A port includes a power supply pin VBUS, a data transmission pin D+, a data transmission pin D-, and a ground pin GND. The cable electronic tag 401 includes a power supply terminal VDD and two data transmission pins. Each data transmission pin can include two working modes: a sending mode and a receiving mode. That is, each data transmission pin can be used both as a sending port TX and as a receiving port RX. The default working modes of the two data transmission pins of the cable electronic tag 401 are both the receiving mode. That is, the two data transmission ports can only receive data. If the cable electronic tag 401 needs to send data, it is necessary to switch the working mode of one of the data transmission ports from the receiving mode to the sending mode.

[0045] Specifically, D+ of port A 201 is communicatively connected to D+ of port C 202, and D- of port A 201 is communicatively connected to D- of port C 202. D+ of port A 201 and D+ of port C 202 are respectively communicatively connected to a data transmission port of the cable electronic tag 401, and D- of port A 201 and D- of port C 202 are respectively communicatively connected to another data transmission port of the cable electronic tag 401. The power supply pin Vconn of port C 202 is electrically connected to the power supply terminal VDD of the cable electronic tag 401.

[0046] Combined with the above Figures 1-4 , taking the charging of a device using the data line 103 as an example, the power supply method of the cable electronic tag provided in the embodiments of the present application can be applied to a power receiving device, and the power receiving device can be the second electronic device 102 in the above embodiments, that is, a device supporting a type-c port.

[0047] As Figure 5 shown, the power supply method of the cable electronic tag may include the following steps:

[0048] S510: When sending a first notification message to the power supply device, control the power supply pin to be powered on.

[0049] Among them, the first notification message is used to indicate reading the cable information of the data line.

[0050] S520: When receiving the cable information of the data line, control the power supply pin to be powered off.

[0051] In this embodiment, when the power receiving device needs to obtain the cable information of the data line, the power supply pin is controlled to be powered on; when the power receiving device receives the cable information of the data line, the power supply pin is controlled to be powered off. Using the power supply pin in the first end of the data line to supply power to the cable electronic tag, there is no need to additionally increase a voltage stabilizing device, so the hardware cost can be reduced. Moreover, only when the power receiving device needs to obtain the cable information, the power receiving device will control the power supply pin to be powered on and supply power to the cable electronic tag through the power supply pin. When receiving the cable information, the power receiving device controls the power supply pin to be powered off, that is, no longer supplies power to the cable electronic tag. Thus, dynamic control of the power supply pin is achieved, that is, dynamic control of the power supply to the cable electronic tag is achieved, and there is no need to constantly supply power to the cable electronic tag, thereby avoiding the problem of energy consumption loss caused by constant power supply.

[0052] The above steps will be described in detail below, as specifically shown below:

[0053] In S510, the above-mentioned first end is the end where the data line is connected to the power receiving device and is used to charge the power receiving device. Therefore, the first end is also referred to as the charging end. The second end is the end where the data line is connected to the power supply device and is used to receive electrical energy from the power supply device to charge the power receiving device. Therefore, the second end is also referred to as the power supply end. The above-mentioned power supply pin is a pin in the first end and is used to supply power to the components inside the data line. When the data line is an A-to-C cable, this power supply pin is the Vconn pin, which can supply power to the cable electronic tag in the A-to-C cable or other components that need power supply, such as sensors or meters.

[0054] Exemplarily, when the power receiving device needs to be charged, the power receiving device needs to obtain the cable information of the data line. At this time, the power receiving device can send a first notification message to the power supply device indicating to read the cable information of the data line, and at the same time control the power supply pin in the first end to be powered on. In this way, the power supply pin can supply power to the cable electronic tag. When the cable electronic tag is powered on, the power receiving device can obtain the cable information of the cable electronic tag, ensuring the safety and efficiency of charging.

[0055] Exemplarily, the above-mentioned first notification message can be that the power receiving device notifies the power supply device to read the cable information in the cable electronic tag by the power supply device, that is, the power supply device directly interacts with the cable electronic tag. Subsequently, the power receiving device can directly obtain the cable information of the data line from the power supply device.

[0056] Exemplarily, the above-mentioned first notification message can also be that the power receiving device notifies the power supply device that the power receiving device is about to read the cable information in the cable electronic tag, that is, the power receiving device directly interacts with the cable electronic tag. That is, in this embodiment, the cable information can be directly obtained by the power receiving device communicating with the cable electronic tag, or the power supply device can first communicate with the cable electronic tag to obtain the cable information, and then the power receiving device communicates with the power supply device to obtain the cable information. In this way, the flexibility of the cable information acquisition method can be improved.

[0057] This embodiment does not limit the specific power-on process. For example, the power receiving device can be connected to the power supply pin through a hardware switch, and the power receiving device can control the conduction or disconnection of the hardware switch to power on the power supply pin. The hardware switch can be, for example, a field effect transistor. Another example is that the power receiving device can also control the power on or off of the power supply pin by outputting a level signal. For example, when the power receiving device outputs a high level, the power supply pin is powered on, and when the power receiving device outputs a low level, the power supply pin is powered off.

[0058] In S520, exemplarily, when the power receiving device receives the cable information, it can control the power supply pin to be powered off, thereby stopping supplying power to the cable electronic tag. In this way, the energy consumption loss caused by constant power supply and the heating of the data line can be reduced, and the service life of the data line can be extended.

[0059] In this embodiment, the cable electronic tag is dynamically powered in a combination of software and hardware. The traditional voltage stabilizing device is cancelled, reducing the hardware cost. At the same time, there is no need to continuously power the cable electronic tag, further reducing the energy consumption loss and extending the service life of the data cable.

[0060] In some embodiments, the above notification message may include a first notification message, which is used to instruct the power supply device to set the state of the sending port of the power supply device to a first target state, and the first target state is used to enable the power supply device to release the control right of the data cable.

[0061] Based on this, in some embodiments, after S510, the power supply method of the cable electronic tag may further include the following steps:

[0062] In the case of receiving the response message of the first notification message sent by the power supply device, send a first cable information reading request to the cable electronic tag; wherein, the power supply device sets the state of the sending port of the power supply device to a first state in response to the first notification message, and in the first state, the power supply device releases the control right of the data cable;

[0063] Receive the cable information of the data cable sent by the cable electronic tag in response to the first cable information reading request.

[0064] When the three terminals share the same bus for communication, the power supply device's release of the control right of the data cable means that the power supply device neither actively drives the signal nor pulls down or pulls up the voltage, thereby avoiding affecting the communication between the power receiving device and the cable electronic tag. Exemplarily, the first state may be a high impedance state.

[0065] That is, before the power receiving device communicates with the cable electronic tag to obtain the cable information, the power receiving device may first send a first notification message to the power supply device. After receiving the first notification message, the power supply device can set its own sending port (TX) to the first state to avoid affecting the communication between the power receiving device and the cable electronic tag. And return a response message to the power receiving device. After receiving the response message returned by the power supply device, the power receiving device can send a first cable information reading request to the cable electronic tag. The first cable information reading request is used to request the cable information of the data cable from the cable electronic tag. The first cable information reading request may include, but is not limited to, the identifier of the power receiving device, the identifier of the data cable, etc.

[0066] After receiving the first cable information reading request, the cable electronic tag can return the cable information of the data cable to the power receiving device. Considering that by default, both data transmission ports of the cable electronic tag are in the receiving mode, in order to ensure the normal transmission of the cable information, the cable electronic tag needs to first switch the working mode of one of the data transmission ports from the receiving mode to the sending mode. This can ensure the normal transmission of the cable information.

[0067] Exemplarily, it is assumed that the cable electronic tag includes a data transmission port 1 and a data transmission port 2. The cable electronic tag receives a first cable information reading request through the data transmission port 2. After receiving the first cable information reading request, the cable electronic tag needs to first switch the working mode of the data transmission port 1 to the sending mode, and then send the cable information to the power receiving device through the data transmission port 1. Thus, the power receiving device can obtain the cable information.

[0068] In this embodiment, the power receiving device can communicate with the cable electronic tag to directly obtain the cable information. Before communicating with the cable electronic tag, the power receiving device first sends a first notification message to the power supply device, avoiding the influence of the power supply device on the communication between the power receiving device and the cable electronic tag, and ensuring the accuracy of data transmission.

[0069] In order not to affect the interaction between the power supply device and the power receiving device, in some embodiments, the above S520 may include the following steps:

[0070] When receiving the cable information of the data line, send a second notification message to the power supply device; wherein, in response to the second notification message, the power supply device switches the state of the sending port of the power supply device from the first state to the second state;

[0071] When receiving the response message of the second notification message sent by the power supply device, control the power supply pin to power off.

[0072] The above second state may be the state of the sending port before the power supply device receives the first notification message, that is, the non-high impedance state. The second notification message is used to notify the power supply device to restore the state of its own TX, providing a basis for the subsequent communication between the power receiving device and the power supply device.

[0073] Exemplarily, after receiving the cable information, the power receiving device can send a second notification message to the power supply device, indicating that the power receiving device has successfully obtained the cable information. After receiving the second notification message, the power supply device restores the state of its own TX, that is, switches from the first state to the original state, and restores the control right of the power supply device over the data line.

[0074] After the power supply device restores the state of its own TX, it can return a response message to the power receiving device. After receiving the response message, the power receiving device can control the power supply pin to power off and stop powering the cable electronic tag.

[0075] In this embodiment, after the power receiving device receives the cable information, it can resume communication with the power supply device, control the power supply pin to power off, and stop powering the cable electronic tag, realizing dynamic power supply to the cable electronic tag. While reducing the power supply cost, it reduces the heat generation of the data line and extends the service life of the data line.

[0076] In some embodiments, the power supply of the cable electronic tag may further include the following steps:

[0077] Receiving the cable information of the data line sent by the power supply device; wherein, in response to the first notification message, the power supply device sends a second cable information reading request to the cable electronic tag, and in the case of receiving the cable information of the data line sent by the cable electronic tag in response to the second cable information reading request, the power supply device sends the cable information of the data line to the power receiving device.

[0078] In this embodiment, the power receiving device can indirectly obtain the cable information through the power supply device. That is, the power supply device first directly interacts with the cable electronic tag to obtain the cable information, and then sends the cable information to the power receiving device together with the power receiving device.

[0079] Exemplarily, after receiving the first notification message, the power supply device sends a second cable information reading request to the cable electronic tag. After receiving the second cable information reading request, the cable electronic tag sends the cable information to the power supply device. After receiving the cable information, the power supply device forwards the cable information to the power receiving device.

[0080] In this embodiment, the power receiving device can indirectly obtain the cable information of the data line through the power supply device, which improves the flexibility of the cable information acquisition method and can be applied to more scenarios.

[0081] In some embodiments, after S510, the power supply method of the cable electronic tag may further include the following steps:

[0082] Receiving a third notification message sent by the power supply device, where the third notification message is sent by the power supply device in the case of receiving the first notification message;

[0083] In response to the third notification message, setting the state of the sending port of the power receiving device to a third state, where in the third state, the power receiving device releases the control right of the data line.

[0084] Exemplarily, after receiving the first notification message sent by the power receiving device, indicating that the cable electronic tag has been powered on, in order to ensure the normal communication between the power supply device and the cable electronic tag, the power supply device may first send a third notification message to the power receiving device to notify the power receiving device that the power supply device is about to read the cable information.

[0085] After receiving the third notification message, the power receiving device automatically sets its TX to the third state to avoid affecting the communication between the power supply device and the cable electronic tag. Exemplarily, the third state may be a high impedance state.

[0086] Before the power supply device communicates with the cable electronic tag to obtain cable information, in response to the third notification message sent by the power supply device, its TX is set to the third state first, which can avoid affecting the communication between the power supply device and the cable electronic tag and ensure the accuracy of the cable information.

[0087] In some embodiments, before S520, the power supply method of the cable electronic tag may further include the following steps:

[0088] Receive a fourth notification message sent by the power supply device, where the fourth notification message is sent by the power supply device when it receives the cable information of the data line sent by the cable electronic tag;

[0089] In response to the fourth notification message, switch the state of the sending port of the power receiving device from the third state to the fourth state;

[0090] Send a third cable information reading request to the power supply device;

[0091] Receive the cable information of the data line sent by the power supply device, including:

[0092] Receive the cable information of the data line sent by the power supply device in response to the third cable information reading request.

[0093] The fourth state is a state that enables the power receiving device to communicate with the power supply device, for example, it can be a non-high impedance state. Exemplarily, after the power supply device receives the cable information returned by the cable electronic tag, in order to ensure that the cable information can be accurately fed back to the power receiving device, the power supply device needs to send a fourth notification message to the power receiving device first to notify the power receiving device to update the state of its own TX. After receiving the fourth notification message, the power receiving device can restore the state of its own TX, providing conditions for the communication between the power receiving device and the power supply device.

[0094] After the power receiving device restores the state of its own TX, it can send a third cable information reading request to the power supply device to request the power supply device to obtain the cable information of the data line. After receiving the third cable information reading request, the power supply device can send the cable information to the power receiving device. Thus, the power receiving device indirectly obtains the cable information through the power supply device.

[0095] This embodiment can not only directly communicate with the cable electronic tag to obtain cable information, but also indirectly obtain cable information through the power supply device, which improves the flexibility of the cable information. Moreover, before the power receiving device communicates with the power supply device to obtain cable information, it first restores the state of its own TX in response to the fourth notification message sent by the power supply device, ensuring the normal communication between the power receiving device and the power supply device, and further ensuring the accuracy of the cable information.

[0096] Based on the current UFCS protocol, taking the A-to-C cable as an example, the communication process among the power receiving device, the power supply device, and the cable electronic tag will be described. Before the power receiving device and the power supply device communicate through the A-to-C cable, they need to handshake based on the UFCS protocol first. After the handshake is successful, the power supply device can charge the power receiving device through the A-to-C cable or transmit data to the power receiving device through the A-to-C cable. The specific handshake process will not be elaborated in this embodiment.

[0097] Figure 6 Taking the communication between the power receiving device and the cable electronic tag to obtain cable information as an example, the communication process among the power receiving device, the power supply device, and the cable electronic tag will be described.

[0098] S610. The power receiving device sends Start_Cable_Detect, indicating that it is about to start reading cable information and controls Vconn to power on. Here, Start_Cable_Detect represents the first notification message in the above embodiment.
