Optionally, in an embodiment, providing power to the equipment rack through the USB interface of the electronic equipment includes:

(1) When it is recognized that an external device is connected to the universal serial bus interface, the first power for handshaking communication is provided to the external device through the power supply pin of the universal serial bus interface;

(2) carry out handshake communication with the external device through the signal pin of the universal serial bus interface;

(3) When the external device is determined to be the device rack according to the handshake result, provide the second power for data forwarding to the device rack through the power supply pin of the USB interface.

In the embodiment of the present application, the universal serial bus interface includes at least a power pin, a signal pin, and an ID pin. When the OTG function is turned on, the power pin is used to provide power to the connected external device, and the signal pin is used Data interaction with connected external devices, ID pins are used to identify different cable endpoints to achieve access detection of external devices, role distinction, etc. Of course, in other embodiments, the universal serial bus interface may also include pins such as CC pins and SBU pins.

Wherein, when the electronic device recognizes that an external device is connected to the universal serial bus interface through the ID pin, it provides the external device with the first power for handshaking communication through the power pin of the universal serial bus interface, and then according to the configured Handshake rules, through the signal pins of the universal serial bus interface to perform handshake communication with the connected external devices. When it is determined that the connected external device is the device rack according to the handshake result, the electronic device further provides the second power for data forwarding to the device rack through the power pin of the USB interface according to the power negotiated with the device rack. Here, there is no specific limitation on the configuration of the handshaking rules, which can be configured by those skilled in the art according to actual needs.

Optionally, in one embodiment, after performing handshake communication with the external device through the signal pin of the universal serial bus interface, it also includes:

When the handshake communication fails, supplying the first power for the handshake communication to the external device through the power supply pin of the USB interface is stopped.

In the embodiment of the present application, when the handshake communication fails, the external device that may be connected is not the aforementioned device rack, or the external device is detected by mistake. At this time, the electronic device determines that there is no device rack that assists in realizing ultra-wideband communication, and accordingly stops passing The power pin of the universal serial bus interface provides the first power for handshaking communication to the external device.

Optionally, in an embodiment, the ultra-wideband data transmission method provided by the present application further includes:

(1) providing the first voltage for access detection to the ID pin of the universal serial bus interface;

(2) When the voltage change value of the ID pin reaches a preset value, provide the ID pin with a second voltage for access detection, wherein the first voltage is smaller than the second voltage;

(3) When it is detected that the ID pin is in a grounded state, it is recognized that an external device is connected to the universal serial bus interface.

The embodiment of the present application further provides an optional external device access detection strategy.

It should be noted that, as an external device as a "peripheral device", the ID pin of its universal serial bus interface is grounded. For example, the ID pin of the external device is grounded through a pull-down resistor, wherein the pull-down resistor can be a separate resistor , can also be composed of multiple resistors connected in series and/or in parallel.

In this way, when an external device is connected to the electronic device, the voltage on the ID pin of the electronic device will be pulled down by the ID pin of the external device. Therefore, in this embodiment of the application, after the electronic device provides the ID pin with the first voltage for access detection, it can determine whether its universal serial bus interface is connected by detecting the voltage change value of the ID pin. external device.

In the embodiment of the present application, after the ID pin of the universal serial bus interface is provided with the first voltage for access detection, the electronic device detects whether the voltage change value of the ID pin reaches a preset value, wherein, after detecting the ID pin When the voltage change value of the pin reaches the preset value, it is determined that an external device may be connected to its universal serial bus interface, and when it is detected that the voltage change value of the ID pin does not reach the preset value, it is determined that no external device is connected Its Universal Serial Bus interface.

Exemplarily, after the electronic device provides the ID pin of its universal serial bus interface with the first voltage for access detection, it detects the voltage of the ID pin in real time, obtains the real-time voltage of the ID pin, and calculates the second voltage. The calculated voltage difference between a voltage and the real-time voltage is used as the voltage change value of the ID pin.

It should be noted that since the ID pin of the external device is grounded, when the external device is connected to the USB interface of the electronic device, the ID pin of the electronic device will also be grounded, thereby pulling down the voltage of the ID pin to 0V. Therefore, in the embodiment of the present application, the preset value for judging whether the USB interface may be connected to an external device is set as the voltage value of the first voltage, for example, the electronic device is using the ID of its USB interface. When the provided first voltage is 0.5V, the aforementioned preset value is also configured as 0.5V.

As above, when the voltage change value of the ID pin reaches the preset value, that is, when an external device may be connected to the USB interface, the electronic device further provides the ID pin with a second voltage for external device access detection , wherein, the second voltage can be understood as a normal voltage used for external device access detection in the related art, and the first voltage is smaller than the second voltage.

Among them, when the electronic device completes the detection of the voltage change value on its ID pin, and detects that the voltage change value reaches the preset value, that is, when it is determined that there may be an external device connected to its universal serial bus interface, it is an ID. The pin provides a second voltage for external device access detection, that is, the ID pin is pulled up to a high voltage.

It should be noted that, in the embodiment of the present application, the first voltage previously provided for the ID pin is smaller than the second voltage currently provided for the ID pin, and the first voltage is much lower than the second voltage. For example, the first voltage provided by the electronic device to its ID pin is 0.5V, and when it is detected that the voltage change value of the ID pin reaches a preset value, the second voltage provided to its ID pin is 3.3V.

After providing the second voltage to the ID pin, the electronic device detects the state of the ID pin to obtain the current state of the ID pin. Then, according to the obtained current state, it is determined whether there is an external device connected to the universal serial bus interface.

It should be noted that since the ID pin of the external device is grounded, when the external device is connected to the USB interface of the electronic device, the ID pin of the electronic device will also be grounded. When the universal serial bus interface of the electronic device is connected, the ID pin of the electronic device will be in a ground state.

Therefore, in the embodiment of the present application, when it is detected that the current state of the ID pin is a grounded state, it is recognized that an external device is connected to the USB interface; and when the current state of the ID pin is not a grounded state, No external device was detected connected to the USB interface.

The external device access detection strategy provided by the embodiment of the present application first provides a low voltage for the ID pin of the universal serial bus interface, and judges the universal serial bus according to whether the voltage change value of the ID pin reaches a preset value. Whether the interface may be connected to an external device, and then when it is determined that the universal serial bus interface may be connected to an external device, a high voltage for external device access detection is provided to the ID pin to realize the access detection of the external device . Therefore, it is only necessary to provide a high voltage for the ID pin in a short period of time, and provide a low voltage for the ID pin in a relatively long period of time. Corrosion will be much lower than the corrosion caused by high voltage to the universal serial bus interface, and it can be almost ignored. In this way, the service life of the universal serial bus interface can be improved.

Optionally, in an embodiment, after providing the second power for data forwarding to the equipment rack through the power supply pin of the universal serial bus interface, the method further includes:

When the temperature value of the universal serial bus interface reaches the preset temperature value, stop supplying the second power for data forwarding to the equipment rack through the power supply pin of the universal serial bus interface.

It is understandable that if the temperature of the USB interface is too high, it may burn the USB interface and even damage the entire electronic device. However, when the electronic device supplies power to the device rack through the USB interface, the temperature of the USB interface will rise rapidly. In order to avoid damage to the electronic equipment caused by power supply to the equipment rack, in the embodiment of the present application, the electronic equipment obtains the universal serial bus interface from the temperature sensor provided at the universal serial bus interface in real time during the period of supplying power to the equipment rack. temperature value, and after obtaining the temperature value of the universal serial bus interface each time, it is judged whether the obtained temperature value reaches the preset temperature value, wherein the preset temperature value is used to describe the temperature value of the universal serial bus interface If it is too high, the specific experience value can be taken by those skilled in the art according to actual needs.

When the temperature value of the universal serial bus interface reaches the preset temperature value, the power supply pin of the universal serial bus interface is stopped to provide the second power for data forwarding to the device rack, thereby preventing the temperature of the universal serial bus interface from continuing raised.

For example, the preset temperature value can be set to 50°C. If the obtained temperature value of the USB If the temperature value of the interface is 51° C., the electronic device stops providing the second power for data forwarding to the device rack through the power pin of the universal serial bus interface.

Optionally, in an embodiment, after providing the device rack with the second power for data forwarding through the power supply pin of the universal serial bus interface, the method further includes:

When there is no need for communication with the external ultra-wideband device, after stopping providing the second power for data forwarding to the device rack through the power pin of the universal serial bus interface.

In the embodiment of the present application, when it is recognized that there is no need for communication with the external ultra-wideband device, the electronic device stops providing the second power for data forwarding to the device rack through the power pin of the universal serial bus interface.

For example, when the electronic device completes all data transmission with the external ultra-wideband device, or receives an input communication end instruction, it determines that there is currently no communication requirement with the external ultra-wideband device.

In this way, after the electronic device completes the data transmission with the external UWB device, the power supply to the device bracket is stopped, which can not only reduce the power consumption of the electronic device, but also reduce the risk of electric leakage of the electronic device.

Optionally, in an embodiment, the communication data includes the device identification of the external UWB device, and after the communication data is transmitted with the device rack through the Universal Serial Bus interface, it also includes:

Display the device control interface corresponding to the external UWB device;

Receive control commands for external ultra-wideband devices through the device control interface;

The control command is sent to the equipment bracket through the universal serial bus interface, so that the equipment bracket sends the control command to the external ultra-wideband device for execution through the ultra-wideband communication protocol.

Wherein, the device identifier of the external ultra-wideband device is used to uniquely represent the external ultra-wideband device, and relevant information can be selected by those skilled in the art according to actual needs as the device identifier of the external ultra-wideband device. For example, the MAC address of the external ultra-wideband device can be used as its device ID.

In the embodiment of the present application, the external ultra-wideband device may use its own device identification as communication data, and send it to the device rack through the ultra-wideband communication protocol. Correspondingly, when receiving the device identifier sent by the external ultra-wideband device, the device holder sends the device identifier to the electronic device via the universal serial bus interface of the electronic device. Correspondingly, the electronic device will receive the device identification of the external UWB device sent by the device bracket through the universal serial bus interface.

For example, the external ultra-wideband device can send its device identification to the outside in a low-frequency mode of only sending but not receiving.

As above, after the electronic device receives the device identifier of the external ultra-wideband device forwarded by the device holder through the universal serial bus interface, the electronic device uses the received device identifier of the external ultra-wideband device to remotely control the external ultra-wideband device.

Because the device identifier of the external ultra-wideband device can uniquely represent the external ultra-wideband device. Therefore, after the electronic device receives the device identifier of the external ultra-wideband device forwarded by the device holder, it can identify the identity of the external ultra-wideband device through the device identifier. Afterwards, the electronic device displays a device control interface corresponding to the external ultra-wideband device according to the identified identity of the external ultra-wideband device. Therefore, the external ultra-wideband device is controlled through the device control interface.

For example, if the external ultra-broadband device is a home appliance, after the electronic device receives the device identification sent by the home appliance through the device bracket, it can identify the home appliance according to the device identification, so as to display the device control interface corresponding to the home appliance for the user to control through the device interface for home appliance control.

In this way, the user does not need to search for an application program for controlling the external ultra-wideband device from among the many application programs installed on the electronic device, so as to meet the requirement of quick start control.

Wherein, the device control interface is configured to generate control instructions for controlling the external ultra-wideband device according to user operations.

Correspondingly, in the process of displaying the device control interface, the electronic device receives a control instruction for the external ultra-wideband device through the displayed device control interface. When the control command for the external ultra-wideband device is received through the device control interface, the electronic device sends the control command to the device bracket through the universal serial bus interface, and the device bracket forwards the control command to the external ultra-wideband device through the ultra-wideband communication protocol. Broadband device implementation.

For example, please refer to Figure 5. The electronic device recognizes that the external ultra-broadband device is a smart fan, and correspondingly displays the device control interface corresponding to the smart fan. As shown in Figure 5, the device control interface includes three controls, which are used for The power-on control for controlling the smart fan to be turned on or off, the circulating air control for controlling the smart fan to turn on or off the circulating air mode, and the timing power-on control for controlling the smart fan to be turned on at a fixed time. Based on the device control interface, the user can click the power-on control to generate a power-on control command for the smart fan. The electronic device further forwards the power-on control command to the smart fan through the device bracket. After that, if the user wants to turn on the circulating air mode of the smart fan, he can click the circulating air control to generate a circulating air control command for the smart fan, and the electronic device further forwards the circulating air control command to the smart fan via the device bracket. Fan. After receiving the circulating air control command, the smart fan will turn on the circulating air mode accordingly.

Optionally, in an embodiment, the control instruction is sent to the equipment rack through a universal serial bus interface, so that the equipment rack sends the control instruction to an external ultra-wideband device for execution through an ultra-wideband communication protocol, including:

When the mobile network is unavailable or the short-distance control mode is currently enabled, the control command is sent to the equipment bracket through the universal serial bus interface, so that the equipment bracket sends the control command to the external ultra-wideband device for execution through the ultra-wideband communication protocol.

In the embodiment of the present application, the electronic device is provided with a short-distance control mode. In the short-distance control mode, the electronic device issues control commands through the device bracket to control external ultra-wideband devices. Correspondingly, the electronic device is also provided with a mode switching control for turning on and off the short-distance control mode, and the electronic device receives a user operation through the mode switching control, and correspondingly turns on or off the short-distance control mode.

In addition, when the electronic device receives a control command for the external ultra-wideband device without turning on the short-distance control mode, it first identifies whether the current mobile network is available, and if the mobile network is not available, the electronic device also performs control commands through the device bracket forwarding, used to control external UWB devices.

Optionally, in an embodiment, the ultra-wideband data transmission method provided by the present application further includes:

When the mobile network is available and the short-distance control mode is currently disabled, the control command is sent to the external ultra-wideband device through the mobile network for execution.
