[0022] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0023] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0024] The main solution of the embodiment of the present application is: controlling the fault detection module to perform a read operation on each external device connected to the electronic device through the USB port; when an external device with a communication abnormality with the electronic device is detected based on the read operation, the external device with a communication abnormality with the electronic device is used as the target external device, and the target USB connector corresponding to the USB port to which the target external device is connected is determined; and controlling the repair module to perform a reconnection operation on the connection path between the target USB connector and the power supply end to re-power on the target external device.

[0025] During the application of the external devices in the prior art, when there are problems such as electromagnetic interference, insufficient power supply, signal attenuation, etc., the external devices may fail abnormally, making it impossible for the electronic equipment to be put into normal use. If the electronic equipment is to be put into use again, it is necessary to manually plug and unplug the external device or restart it to control the external device to re-enter the normal working state. However, the manual plug and unplug operation or restart operation requires manual intervention by the user, so it is inconvenient to operate.

[0026] The present application provides a solution, by which a fault repair system is set up to perform a reading operation on each external device connected to the electronic device, so as to judge whether there is a communication abnormality in the communication connection between each external device and the electronic device according to the reading operation, that is, to judge whether there is a failure phenomenon in the external device connected to the electronic device, to realize automatic detection of the failure of the external device, and when the failure phenomenon of the external device is detected, after determining the target USB connector corresponding to the USB port to which the external device with the failure phenomenon is connected, a connection path between the target USB connector and the power supply end is reconnected, so as to re-power on the external device with the failure phenomenon, that is, by controlling the on-off of the connection path between the target USB connector and the power supply end, the plug-in and unplug operation or the restart operation of the external device with the failure phenomenon is simulated, so as to realize automatic and convenient plug-in and unplug operation or restart operation of the external device without manual intervention.

[0027] It should be noted that the execution subject of this embodiment may be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, etc. The following takes an electronic device as an example to illustrate this embodiment and the following embodiments.

[0028] Based on this, the present application embodiment provides a method for repairing a fault of an external device, referring to Figure 1 , Figure 1 This is a flow chart of a first embodiment of a method for repairing a fault of an external device according to the present invention.

[0029] In this embodiment, the fault repair method of the external device includes steps S10 to S30: Step S10, controlling the fault detection module to perform a read operation on each external device connected to the electronic device through the USB port.

[0030] It should be noted that the fault repair method of the external device implemented in this embodiment is based on the following Figure 2 The proposed fault repair system is implemented. The fault repair system is provided with a plurality of USB connectors, one end of each USB connector is connected to a power supply end, the fault repair system is installed in an electronic device provided with a plurality of USB ports, one USB port corresponds to one USB connector, and the fault repair system includes a fault detection module and a repair module.

[0031] This embodiment controls the fault detection module in the fault repair system to perform communication detection on the external device connected to any USB port of the electronic device to detect whether the external device connected to the electronic device has a failure phenomenon, so as to detect whether the electronic device in the current state is in a normal working state. The detection operation of this embodiment is to control the fault detection module to read each external device connected to the electronic device through the USB port respectively, and obtain the relevant device information on each external device. The relevant device information needs to be transmitted to the fault detection module based on the communication connection between the corresponding external device and the USB port on the electronic device. Therefore, when the external device is in normal operation, it can transmit the relevant device information to the fault detection module based on the communication connection. If the external device fails (i.e., it cannot run), the external device cannot transmit the relevant device information to the fault detection module based on the communication connection. Therefore, based on the fault detection module proposed in this embodiment, it can realize rapid detection and convenient troubleshooting of external devices with failure abnormal state.

[0032] In a feasible implementation manner, step S11 may be further included before step S10: Step S11, obtaining, through the fault detection module, the port correspondence between each of the external devices connected to the electronic device and each of the USB ports and the working status of each of the external devices.

[0033] Before detecting and troubleshooting the abnormal failure status of the external device through the fault detection module, it is necessary to obtain the port correspondence between the external device connected to the electronic device and the USB port on the electronic device, so as to determine the correspondence between the external device and the USB connector in the fault repair system, and determine which USB connector the external device is powered on through, so that the external device can be powered on again by subsequently controlling the conduction status of the path between the USB connector and the power supply end.

[0034] At the same time, it is also necessary to obtain the working status of external devices connected to the electronic device in order to screen out external devices in normal working status. External devices in stopped working status indicate that at the previous moment, whether they are failed has no effect on the operating status of the electronic device, so that external devices in stopped working status can be screened out subsequently to avoid waste of resources due to meaningless detection of external devices in stopped working status.

[0035] It should be noted that the port correspondence and working status in this embodiment can be obtained based on the USB controller in the fault detection module.

[0036] In a feasible implementation, step S10 may include step S12: Step S12, sending a read command to the USB controller in the fault detection module according to a preset interval, controlling the USB controller to perform a read operation on the external device that is in a normal working state based on the read command, so as to obtain a key status code action of the external device that is in a normal working state based on the read operation.

[0037] In this embodiment, in order to improve the timeliness of troubleshooting the operating status of the external device without wasting resources, it is proposed to control the detection module to perform troubleshooting on the external device at a preset interval. It should be noted that the fault detection module in this embodiment is equipped with monitoring software for the external device.

[0038] Specifically: the fault detection module will send a read command to the USB controller in the fault detection module based on the monitoring software at fixed intervals, for example, every 1 second. After receiving the read command, the USB controller will communicate with each external device connected to the electronic device through the USB port to obtain the key status code action corresponding to each external device in the normal working state. At this time, the USB controller will determine whether each external device can return its corresponding key status code action to the USB controller based on the communication with it, and then determine whether the communication connection between the external device and the electronic device is normal.

[0039] In a feasible implementation manner, step S10 may further include steps S13 to S15: Step S13, determining whether the key status code actions corresponding to each of the external devices can be obtained based on the reading operation.

[0040] Communicate with each external device through the USB controller, and judge whether the USB controller can receive the key status code action returned by each external device based on the communication operation, so as to judge whether the communication between each external device and the electronic device is normal, and whether each external device is in a normal operating state. For example, when the external device is a touch screen, the touch screen is connected to the electronic device. At this time, the fault detection module in the electronic device reads the key status code action of the touch screen through the USB controller, and detects whether the key status code action corresponding to the touch screen can be obtained based on the communication relationship between the electronic device and the touch screen, so as to judge whether the communication connection between the touch screen and the electronic device is normal, and whether the touch screen is in a normal operating state.

[0041] Step S14: If the key status code action corresponding to the external device can be obtained based on the reading operation, it is determined that the external device and the electronic device can communicate normally.

[0042] If the USB controller can read the corresponding key status code action from the external device through the read operation, it is considered that the external device and the electronic device can communicate normally. At this time, the external device is in a normal operating state and there is no abnormal failure phenomenon.

[0043] Step S15, if the key status code action corresponding to the external device cannot be obtained based on the read operation, it is determined that there is a communication abnormality between the external device and the electronic device, and the step of taking the external device with the communication abnormality as the target external device is executed when the external device with the communication abnormality is detected based on the read operation.

[0044] If the USB controller cannot read the corresponding key status code action from the external device through the read operation, it is considered that the external device and the electronic device cannot communicate normally. At this time, the external device is in a failed state and needs to be plugged in or restarted to re-power on the external device so that it can release the occupied resources and restore normal performance.

[0045] Step S20, when an external device with abnormal communication with the electronic device is detected based on the read operation, the external device with abnormal communication with the electronic device is used as a target external device, and a target USB connector corresponding to the USB port to which the target external device is connected is determined.

[0046] Based on step S15, when the fault detection module detects that a certain external device cannot return its corresponding key status code action to the USB controller, it is considered that there is a communication abnormality between the external device and the electronic device, and the external device is determined to be in a failed state. Therefore, the external device is determined as a target external device that needs to be powered on again, and the USB port to which the target external device is connected is determined to correspond to the USB connector in the fault repair system, and the corresponding USB connector is determined to be the target USB connector, so that the external device is powered on again by controlling the on-off state of the path between the target USB connector and the power supply end, thereby achieving power-on of the external device that has failed without the need for manual plug-in and unplugging or restarting of the external device.

[0047] Step S30, controlling the repair module to perform a reconnection operation on the connection path between the target USB connector and the power supply end, so as to re-power on the target external device.

[0048] In this embodiment, a repair module is provided in the fault repair system to reconnect the connection path between the target USB connector and the power supply end, that is, the connection path is disconnected for a certain period of time and then reopened to achieve the power-on operation of the target external device.

[0049] That is, this embodiment controls the connection path between the USB connector corresponding to the external device in the failed state and the power supply end, and reconnects the connection path, so that the power supply current at the power supply end first stops supplying power to the external device in the failed state and maintains it for a certain period of time, and then re-supplies the external device in the failed state, thereby simulating the plug-in or restart operation of the external device in the failed state without manual intervention, thereby improving the convenience and quickness of the re-powering operation of the external device to a certain extent.

[0050] In a feasible implementation, step S30 may include steps S31-S32: Step S31, controlling the repair module to determine the USB connector corresponding to the USB port to which the target external device is connected as the target USB connector according to the port correspondence of the target external device.

[0051] Step S32, disconnecting the connection between the target USB connector and the power supply end, and connecting the connection between the target USB connector and the power supply end after a preset time.

[0052] Because the external device connected to the electronic device in this embodiment is powered by the electronic device, the specific power supply path is: the power supply end transmits the power supply to the USB connector through the connection path between the power supply end and the USB connector, and the USB connector transmits the connected power supply to the corresponding USB port through the corresponding USB communication connection method. The USB port supplies power to the external device connected to the USB port according to the connected power supply.

[0053] Therefore, based on the above power supply path, the present embodiment proposes that after determining that the target external device is in a failed state, firstly, according to the port correspondence of the target external device, a target USB connector for powering the target external device is obtained, and the connection path between the target USB connector and the power supply end is controlled. First, the connection relationship between the target USB connector and the power supply end is controlled to be disconnected, and the electronic device is controlled to stop the power supply operation to the target external device, thereby simulating the operation of unplugging the connection interface of the target external device from the electronic device, and controlling the target external device to enter a shutdown / standby state. After waiting for a preset period of time, the connection relationship between the target USB connector and the power supply end is reconnected, and the electronic device is controlled to start powering the target external device, thereby simulating the operation of inserting the connection interface of the target external device into the electronic device, and controlling the target external device to enter an on state, so as to achieve plugging and unplugging or restarting the external device with a failed state without manual intervention.

[0054] The preset duration is set based on actual application requirements, and the preset duration in this embodiment is 1 to 3 seconds.

[0055] The present application also provides a fault recovery system, referring to Figure 2 As shown, the fault recovery system is provided with a plurality of USB connectors, one end of each USB connector is connected to a power supply end (i.e. Figure 2The fault recovery system is installed in an electronic device provided with a plurality of USB ports, one USB port corresponds to one USB connector, and the fault recovery system includes: A fault detection module is used to perform a read operation on each external device connected to the electronic device through a USB port; The fault detection module is further used to, when an external device with abnormal communication with the electronic device is detected based on the reading operation, take the external device with abnormal communication with the electronic device as a target external device, and determine a target USB connector corresponding to the USB port to which the target external device is connected; The repair module is used to perform a reconnection operation on the connection path between the target USB connector and the power supply end to re-power on the target external device.

[0056] As described in steps S10 to S30, the operation steps between the fault detection module and the repair module will not be repeated here.

[0057] It should be noted that the platform control hub (i.e. Figure 2 and Figure 3 The PCH in the platform control hub is a part of the electronic device. The fault detection module and the repair module are respectively arranged on the platform control hub. The fault detection module realizes the detection of the external device through the platform control hub, and the repair module obtains the detection result of the fault detection module through the platform control hub and outputs the corresponding control signal to the connection line between the USB connector and the power supply end.

[0058] Specifically, refer to Figure 3 As shown, the fault detection module includes a USB controller; The USB controller establishes a connection relationship with each USB port, and the USB controller stores device information of each USB connector corresponding to each USB port.

[0059] Figure 3 This is an example of installing a fault repair system on an electronic device proposed in this embodiment. The fault repair system is connected to the electronic device through a platform control hub on the electronic device. Specifically, a USB controller in the fault repair system is set on the platform control hub, and the platform control hub is provided with a plurality of USB ports for connecting to external devices. At the same time, the USB connector on the fault repair system is connected to the platform control hub, so that the USB controller can obtain the corresponding relationship between the USB port and the USB connector.

[0061] The specific port connection relationship between the USB connector and the platform control hub can be referred to Figure 4 As shown, Figure 4 A schematic diagram showing the connection between the first 2.0 specification USB connector and the platform controller hub.

[0062] The upper end of the USB connector (i.e. Figure 4 UP in the middle) and the lower mouth (i.e. Figure 4 The connection between the DOWN in the upper port and the platform control hub is symmetrical, the D1- pin in the upper port is connected to the USB2_P1_DN in the platform control hub, and the D1+ pin is connected to the USB2_P1_DP in the platform control hub, and an inductor L1 is provided on the two connecting lines, which is the common-mode suppression inductor of the upper USB2.0 communication signal.

[0063] The SSRX1- pin in the upper port is connected to the USB31_P2_RX_DN in the platform control hub, and the SSRX1+ pin is connected to the USB31_P2_RX_DP in the platform control hub; the SSTX1- pin in the upper port is connected to the USB31_P2_TX_DN in the platform control hub, and the SSTX1+ pin is connected to the USB31_P2_TX_DP in the platform control hub, which is used to connect the USB differential signal in the upper USB connector, and a coupling capacitor (i.e. Figure 4 C1 and C2 in the figure are used to isolate external devices and the USB controller to prevent electrical damage and communication failure caused by level mismatch.

[0064] The D0- pin in the lower port is connected to the USB2_P2_DN in the platform control hub, and the D0+ pin is connected to the USB2_P2_DP in the platform control hub. An inductor L2 is provided on the two connecting lines. The inductor L2 is a common-mode suppression inductor for the USB2.0 communication signal of the lower port.

[0065] The SSRX0- pin in the lower port is connected to the USB31_P1_RX_DN in the platform control hub, and the SSRX0+ pin is connected to the USB31_P1_RX_DP in the platform control hub; the SSTX0- pin in the lower port is connected to the USB31_P1_TX_DN in the platform control hub, and the SSTX0+ pin is connected to the USB31_P1_TX_DP in the platform control hub, which is used to connect the USB differential signal in the USB connector, and a coupling capacitor (i.e. Figure 4 C3 and C4 in the figure are used to isolate external devices and the USB controller to prevent electrical damage and communication failure caused by level mismatch.

[0066] in, Figure 3 The power supply terminal in the example shown provides a +5V supply voltage (i.e. Figure 3 +5V_SB in the power supply.

[0067] Furthermore, the repair module includes: A signal control unit; a plurality of USB drive switch devices, one of the USB drive switch devices is connected between the USB connector and the power supply end, and the USB drive switch device is also communicatively connected with the signal control unit, and the signal control unit is used to control the on and off of each of the USB drive switch devices.

[0068] according to Figure 3It can be seen that the signal control unit in the repair module is set on the platform control hub, and each USB connector is connected to the power supply end through a drive switch device. The signal control unit is communicated with each USB drive switch device. After receiving the corresponding control signal, it controls the USB drive switch device between the target USB connector and the power supply end to disconnect based on the control signal, and after a preset time, controls the USB drive switch device to turn on, so as to realize the power-on operation of the target external device.

[0069] There are two ways to connect the USB driver switch device and the signal control unit. The first is to connect directly through the GPIO port on the platform control hub, such as Figure 3 The USB drive switch device 1 shown (i.e. Figure 3 SW1 in), USB driver switch device 2 (i.e. Figure 3 SW2 in), USB driver switch device 3 (i.e. Figure 3 SW3 in), USB driver switch device 4 (i.e. Figure 3 SW4 in the USB driver) and USB driver switch device 5 (i.e. Figure 3 The second method is to connect to the platform control hub through the I / O chip, such as Figure 3 The USB drive switch device 6 (i.e. Figure 3 SW6 in the I / O chip (i.e. Figure 3 The GPIO6 port on the SuperI / O in the I / O chip is connected to the GPIO6 port on the SuperI / O in the I / O chip through the optical fiber connector (i.e. Figure 3 UPC in) or communication bus (i.e. Figure 3 The eSPI in the SPI interface connects to the platform control hub.

[0070] Specifically, Figure 5 for Figure 4 The USB connector in the figure is connected to the power supply end. Figure 5 It can be seen that the USB driver switch device can be a controller (i.e. Figure 5 The two VBus pins in the USB connector are connected to the VOUT1~VOUT3 pins of the controller, which are used to connect the power supply when the controller is turned on (i.e. Figure 5 +5A in the VBus pin), connect the fifth capacitor on the VBus pin (i.e. Figure 5 C5 in), the sixth capacitor (i.e. Figure 5 C6 in the figure) and the seventh capacitor (i.e. Figure 5C7 in the figure is a power supply capacitor, which is used to implement power supply filtering. Among them, the EN pin of the controller is connected to the GPIO port of the platform control hub or the GPIO port of the I / O chip, and is used to perform on-off control according to the control signal transmitted by the signal control unit on the platform control hub. For example, when the control signal connected to the EN pin of the controller is a low-level signal, the EN pin, VIN pin and VIN2 pin are pulled low, and the VIN1 pin and VIN2 pin connected to the power supply end of the controller are not connected to the VOUT1~VOUT3 pins. At this time, the controller cannot output power to the USB connector; when the control signal connected to the EN pin of the controller is a high-level signal, the EN pin, VIN pin and VIN2 pin are pulled high, and the VIN1 pin and VIN2 pin connected to the power supply end of the controller are connected to the VOUT1~VOUT3 pins. At this time, the controller outputs power to the USB connector.

[0071] The driving power of the USB controller is provided by the USB power supply terminal (i.e. Figure 5 USBPWR in the .

[0072] It should be noted that the EN pin, the VIN pin and the VIN2 pin are connected with a first resistor R1, a second resistor R2 and an eighth capacitor C8 for filtering. The model of the USB connector used in this example is A052010220.
