[0029] The following is in conjunction with the appendix Figures 1 to 10 The signal compensation circuit, signal compensation method, signal compensation device, electronic device, and readable storage medium provided in this application will be described in detail through specific embodiments and application scenarios.

[0030] In some embodiments of this application, a signal compensation circuit is provided. Figure 1 Schematic diagrams of signal compensation circuits provided in some embodiments of this application are shown. Figure 2 Schematic diagrams of electronic devices provided in some embodiments of this application are shown, such as... Figure 1 and Figure 2 As shown, the signal compensation circuit 100 is applied to the electronic device 200. The signal receiving end of the signal compensation circuit is connected to the serial bus interface 202 of the electronic device 200, and the signal output end of the signal compensation circuit is connected to the data transceiver module 204 of the electronic device 200.

[0031] The signal compensation circuit comprises: an amplitude acquisition circuit 110, a first end of the amplitude acquisition circuit 110 being connected with the serial bus interface 202, for acquiring a first voltage amplitude of a first signal, the first signal being a received signal of the serial bus interface 202; a controller 120, a receiving end of the controller 120 being connected with a second end of the amplitude acquisition circuit 110; a driver 130, a first end of the driver 130 being connected with an output end of the controller 120, and a second end of the driver 130 being connected with a data transceiver module 204 of the electronic device 200; the controller 120 is configured to control the driver 130 to compensate the first signal according to the first voltage amplitude and a preset voltage amplitude, so that the first voltage amplitude is within a preset amplitude range, the preset amplitude range being a range determined according to the preset voltage amplitude.

[0032] In the embodiments of the present application, the serial bus interface 202 can be different types of USB (Universal Serial Bus) interfaces, such as Type-A interface, Type-B interface, Type-C interface, etc.

[0033] In the embodiments of the present application, the current insertion loss value is the insertion loss value on the signal path when the serial bus interface 202 receives the first signal.

[0034] For example, the controller 120 can determine the corresponding current insertion loss value according to the first voltage amplitude by looking up a table.

[0035] In the embodiments of the present application, the amplitude acquisition circuit 110 can amplify the first voltage amplitude of the first signal, and can also convert the analog signal corresponding to the first voltage amplitude into a corresponding digital signal. The controller 120 can receive the first signal and the corresponding first voltage amplitude transmitted by the amplitude acquisition circuit 110, and control the driver 130 based on the first voltage amplitude and the preset voltage amplitude. The preset voltage amplitude is the voltage amplitude at which the electronic devices 200 can stably transmit signals. By comparing the first voltage amplitude with the preset voltage amplitude, it can be determined whether the current signal path has too large insertion loss, and accordingly the driver 130 is controlled to compensate the received first signal, so as to avoid the signal transmission between the two electronic devices 200 being disconnected.

[0036] In the embodiment of the present application, the amplitude acquisition circuit 110 can acquire the first voltage amplitude of the first signal received by the serial bus interface 202. The data line of the serial bus includes DP (positive) and DN (negative), and the amplitude acquisition circuit 110 can acquire the DP and DN amplitudes, i.e., the first voltage amplitude, and transmit the first voltage amplitude to the controller 120. The controller 120 controls the driver 130 according to the first voltage amplitude and the preset voltage amplitude, so that the received first signal is compensated by the driver 130. The compensated first signal can be stably received by the electronic device 200, thereby improving the signal transmission stability between the electronic devices 200.

[0037] In the embodiment of the present application, the first signal is a received signal, and the signal compensation circuit 100 can continuously acquire the first voltage amplitude of the first signal acquired by the serial bus interface 202 through the amplitude acquisition circuit 110. Since the first voltage amplitude is continuously acquired, comparison between the first voltage amplitude and the preset voltage amplitude can determine the insertion loss of the corresponding signal path, thereby ensuring the accuracy of the compensation of the first signal by the driver 130 controlled by the first voltage amplitude and the preset voltage amplitude, avoiding the false triggering of the driver 130, and further ensuring the stability of the signal transmission between the two electronic devices 200.

[0038] For example, the two electronic devices 200 are a mobile phone and a vehicle machine, and the serial bus interfaces 202 of the mobile phone and the vehicle machine are connected by a USB line. During vehicle driving, the signal compensation circuit 100 in the mobile phone continuously detects the first voltage amplitude of the first signal received by the mobile phone, and compensates the first signal received by the mobile phone based on the first voltage amplitude and the corresponding preset voltage amplitude, thereby avoiding the disconnection caused by the too low first voltage amplitude of the first signal received by the mobile phone. The signal compensation circuit 100 in the vehicle machine continuously detects the first voltage amplitude of the first signal received by the vehicle machine, and compensates the first signal received by the vehicle machine based on the first voltage amplitude and the corresponding preset voltage amplitude, thereby avoiding the disconnection caused by the too low first voltage amplitude of the first signal received by the vehicle machine.

[0039] In the embodiment of the present application, the signal compensation circuit 100 is arranged in the electronic device 200. The signal compensation circuit 100 can compensate the received first signal based on the continuously acquired first voltage amplitude and the preset voltage amplitude, thereby improving the stability of the signal transmission between the two electronic devices 200.

[0040] In the embodiments of the present application, when the two electronic devices 200 are a vehicle machine and a terminal device respectively, the signal compensation circuit 100 is arranged in the vehicle machine and the terminal device, the signal compensation circuit 100 can detect the first voltage amplitude of the signal path under different driving states of the vehicle, and control the driver 130 to compensate the signal received by the vehicle machine and the terminal device, thereby improving the stability of data transmission between the vehicle machine and the terminal device, and reducing the occurrence of signal disconnection caused by vehicle bumping.

[0041] In some embodiments of the present application, the amplitude acquisition circuit 110 includes an amplification circuit 112 and an analog-digital conversion circuit 114. The first end of the amplification circuit 112 is connected with the serial bus interface 202, and the first end of the analog-digital conversion circuit 114 is connected with the second end of the amplification circuit 112, and the second end of the analog-digital conversion circuit 114 is connected with the receiving end of the controller 120.

[0042] In the embodiments of the present application, the amplification circuit 112 is connected between the serial bus interface 202 and the analog-digital conversion circuit 114, and the amplification circuit 112 can amplify the detected first voltage amplitude and transmit the amplified first voltage amplitude to the analog-digital conversion circuit 114 for analog-digital conversion.

[0043] In the embodiments of the present application, the signal compensation circuit 100 amplifies the detected first voltage amplitude signal through the amplification circuit 112, and then converts the signal through the analog-digital conversion circuit 114 to obtain a corresponding digital signal. The processed digital signal is transmitted to the controller 120, so that the controller 120 can control the driver 130 according to the signal. By arranging the amplification circuit 112 and the analog-digital conversion circuit 114 in the amplitude acquisition circuit 110, the accuracy of the first voltage amplitude transmitted by the amplitude acquisition circuit 110 to the controller 120 can be ensured.

[0044] In some embodiments of the present application, the driver 130 includes a Schmitt trigger.

[0045] In the embodiments of the present application, the controller 120 controls the Schmitt trigger to shape the waveform of the first signal, so that the waveform of the compensated first signal meets the transmission condition, and the stability of signal transmission between the two electronic devices 200 is further ensured.

[0046] Specifically, in the Schmitt trigger, the two comparison voltages are respectively referred to as upper limit voltage (Vupper) and lower limit voltage (Vlower). When the input first signal is higher than the upper limit voltage, the output level becomes high, and when the input first signal is lower than the lower limit voltage, the output level becomes low. When the input signal is between the upper and lower limit voltages, the output level remains unchanged, thereby shaping the waveform of the first signal and improving the stability of signal transmission.

[0047] In some embodiments of the present application, an electronic device is provided, such as Figure 2 As shown, the electronic device 200 includes the signal compensation circuit 100 in any of the above embodiments, a data transceiver module 204, and a serial bus interface 202, the serial bus interface 202 is connected to the signal compensation circuit 100, the data transceiver module 204 is connected to the signal compensation circuit 100, and the signal compensation circuit 100 is arranged between the data transceiver module 204 and the serial bus interface 202.

[0048] For example, the electronic device 200 can be a car machine in a vehicle, and the electronic device 200 can also be a mobile terminal such as a mobile phone or a tablet computer.

[0049] Figure 3 A connection diagram of a car machine and a mobile phone is shown, which is provided in some embodiments of the present application, as shown in Figure 3 As shown, the mobile phone includes a first data transceiver module, a switch, the signal compensation circuit 100, and a first USB interface. The car machine includes a second data transceiver module, the signal compensation circuit 100, and a second USB interface, and the first USB interface and the second USB interface are connected through a data line.

[0050] For example, the data transceiver module can be any module supporting USB data transmission, such as an audio module, a data transmission module, a charging module, etc.

[0051] Figure 4 A connection diagram of a car machine and a mobile phone is shown, which is provided in some embodiments of the present application, as shown in Figure 4 As shown, the mobile phone includes a first data transceiver module, a switch, the signal compensation circuit 100, and a first USB interface. The car machine includes a second data transceiver module, the signal compensation circuit 100, and a second USB interface. The first data transceiver module and the second data transceiver module each include an audio module, a data transmission module, and a charging module. The first USB interface and the second USB interface are connected through a data line.

[0052] In the embodiments of the present application, by arranging the signal compensation circuit 100 in the electronic device 200, the signal compensation circuit 100 can compensate the received first signal according to the continuously collected first voltage amplitude and the preset voltage amplitude, thereby improving the stability of signal transmission between two electronic devices 200.

[0053] In the embodiments of the present application, when the two electronic devices 200 are a vehicle machine and a terminal device respectively, the signal compensation circuit 100 is arranged in the vehicle machine and the terminal device, the signal compensation circuit 100 can detect the first voltage amplitude of the signal path under different driving states of the vehicle, and control the driver 130 to compensate the signal received by the vehicle machine and the terminal device, thereby improving the stability of data transmission between the vehicle machine and the terminal device, and reducing the occurrence of signal disconnection caused by vehicle bumping.

[0054] In some embodiments of the present application, a signal compensation method is provided, Figure 5 The flowchart of the signal compensation method provided in some embodiments of the present application is shown in FIG. 5. Figure 5 As shown in FIG. 5, the signal compensation method comprises the following steps:

[0055] In the embodiments of the present application, the signal compensation method is applied to the signal compensation circuit in any of the above embodiments, and the signal compensation circuit comprises an amplitude acquisition circuit, a controller and a driver.

[0056] Step 502: acquiring a first voltage amplitude of a first signal;

[0057] In the embodiments of the present application, the first voltage amplitude is the voltage amplitude corresponding to the received first signal in the process of signal transmission between the two electronic devices.

[0058] Step 504: controlling the driver to compensate the first signal according to the first voltage amplitude and a preset voltage amplitude, so that the first voltage amplitude is within a first amplitude range, and the first amplitude range is a range determined according to the preset voltage amplitude.

[0059] In the embodiments of the present application, the preset voltage amplitude is the voltage amplitude at which the signal transmission between the electronic devices can be stable, by comparing the first voltage amplitude with the preset voltage amplitude, it can be determined whether the insertion loss of the signal path is too large, and the driver is controlled to compensate the received first signal accordingly, thereby avoiding the disconnection of signal transmission between the two electronic devices.

[0060] In the embodiments of the present application, the first signal is a received signal, the amplitude acquisition circuit of the signal compensation circuit can continuously acquire the first voltage amplitude of the first signal collected by the serial bus interface, so that the insertion loss of the signal path can be determined according to the first voltage amplitude of the first signal and the preset voltage amplitude, and the driver can compensate the first signal according to the continuously detected first voltage amplitude and the preset voltage amplitude, thereby further ensuring the stability of signal transmission between the two electronic devices.

[0061] In the embodiments of the present application, the signal compensation circuit is arranged in the electronic device, and the signal compensation circuit can compensate the received first signal according to the continuously collected first voltage amplitude and the preset voltage amplitude, thereby improving the stability of signal transmission between the two electronic devices.

[0062] Figure 6 A waveform diagram of the first signal before compensation provided in some embodiments of the present application is shown, Figure 7 A waveform diagram of the first signal after compensation provided in some embodiments of the present application is shown, Figure 6 and Figure 7 As shown in the figures, before compensation, the current insertion loss value changes, causing the first voltage amplitude to change, and causing the voltage amplitude of the first signal to be lower than the receiving threshold of the serial bus interface of the electronic device. After the first signal is compensated by the signal compensation circuit, the waveform of the first signal can be shaped, the first voltage amplitude of the first signal is compensated to a reasonable range, and the stability of signal transmission between the electronic devices is improved.

[0063] In the embodiments of the present application, when the two electronic devices are a car machine and a terminal device, the signal compensation circuit is arranged in the car machine and the terminal device, the signal compensation circuit can detect the first voltage amplitude of the signal path under different driving states of the vehicle, and control the driver to compensate the received signal of the car machine and the terminal device according to the first voltage amplitude and the corresponding preset voltage amplitude, thereby improving the stability of data transmission between the car machine and the terminal device and reducing the occurrence of signal disconnection caused by vehicle bumping.

[0064] In some embodiments of the present application, the driver compensates the first signal according to the first voltage amplitude and the preset voltage amplitude, including: determining the running scenario of the electronic device according to the first voltage amplitude and the preset voltage amplitude; and controlling the driver to compensate the first signal according to the running scenario of the electronic device.

[0065] In the embodiments of the present application, the first voltage amplitude and the preset voltage amplitude are compared, and the running scenario of the electronic device is determined based on the comparison, and the driver is selected to compensate the first signal based on the running scenario.

[0066] For example, when the two electronic devices are a car machine and a mobile phone of a vehicle, the connection environment of the car machine and the mobile phone can be determined according to the first voltage amplitude and the preset voltage amplitude, such as: the car machine device is in a vehicle stable driving scenario, the car machine device is in a vehicle bumping driving scenario, the car machine device is in a vehicle accelerating driving scenario, etc.

[0067] In the embodiments of the present application, different compensation strategies of the driver correspond to different running scenarios, and the running scenario of the electronic device can be determined according to the first voltage amplitude and the preset voltage amplitude, and the compensation strategy of the driver for the first signal is set accordingly.

[0068] In the embodiments of the present application, the electronic device can determine the running scenario of the electronic device based on the first voltage amplitude and the preset voltage amplitude, thereby determining the corresponding compensation strategy, improving the accuracy of the driver control, and avoiding the compensation failure of the driver for the first signal.

[0069] In some embodiments of the present application, the running scenario of the electronic device is determined according to the first voltage amplitude and the preset voltage amplitude, including: determining the current insertion loss value, the preset insertion loss value range, and the insertion loss value change rate of the first signal according to the first voltage amplitude and the preset voltage amplitude.

[0070] The vehicle machine device is determined to be in a vehicle smooth driving scenario based on the current insertion loss value being less than the minimum value of the preset insertion loss value range and the insertion loss value change rate being less than the preset change rate.

[0071] The vehicle machine device is determined to be in a vehicle bumpy driving scenario based on the current insertion loss value being within the preset insertion loss value range and the insertion loss value change rate being greater than or equal to the preset change rate.

[0072] The vehicle machine device is determined to be in a vehicle accelerating driving scenario based on the current insertion loss value being within the preset insertion loss value range and the insertion loss value change rate being less than the preset change rate.

[0073] The vehicle machine device is determined to be in an abnormal connection scenario based on the current insertion loss value being greater than the maximum value of the preset insertion loss value range.

[0074] In the embodiments of the present application, the electronic device can determine the current insertion loss value, the preset insertion loss value range, and the insertion loss value change rate of the first signal based on the first voltage amplitude and the preset voltage amplitude. The insertion loss value of the first signal is the insertion loss value of the transmission path of the first signal, the preset insertion loss value range is the insertion loss value range corresponding to the transmission path of the first signal, and the insertion loss value change rate is the change rate of the current insertion loss value over time. For example, the current insertion loss value can be determined according to the first voltage amplitude, and the preset insertion loss value range can be determined according to the preset voltage amplitude. The corresponding relationship between the voltage amplitude and the insertion loss value is stored in the electronic device, and the corresponding insertion loss value can be found by the voltage amplitude, i.e., the corresponding insertion loss value found according to the obtained first voltage amplitude is the current insertion loss value, and the insertion loss value change rate can be determined based on the continuously obtained current insertion loss value and time information. The preset insertion loss value can be found by the preset voltage amplitude, and the preset insertion loss value range can be determined based on the preset insertion loss value, for example, the preset insertion loss value is a, and the target insertion loss value range is 1.1a to 3a.

[0075] In the embodiment of the present application, the electronic device can determine the running scene of the electronic device based on the numerical relationship between the current insertion loss value and the preset insertion loss value range and the insertion loss value change rate, and control the driver to compensate the first signal according to the running scene, thereby improving the accuracy of the driver compensating the first signal.

[0076] In the embodiment of the present application, the electronic device includes a car machine device, which can be connected with a mobile terminal such as a mobile phone or a tablet computer. The following takes the connection between the car machine device and the mobile phone as an example for description.

[0077] For example, the current insertion loss value between the car machine device and the mobile phone is A, the preset insertion loss value range is 1.1a to 3a, and the preset change rate is 1Hz. In the case of detecting 0.9a

[0078] For example, the current insertion loss value between the car machine device and the mobile phone is A, the preset insertion loss value range is 1.1a to 3a, and the preset change rate is 100Hz. In the case of detecting 1.1a

[0079] For example, the current insertion loss value between the car machine device and the mobile phone is A, the preset insertion loss value range is 1.1a to 3a. In the case of detecting A>3a, it is determined that the car machine device is abnormally connected with the mobile phone, and at this time, it is not necessary to count the insertion loss value change rate.

[0080] In the embodiment of the present application, in the case that the electronic device includes a car machine device, the car machine device can determine the corresponding current insertion loss value and preset insertion loss value range through the first voltage amplitude and the preset voltage amplitude, and can determine the insertion loss value change rate according to the current insertion loss value. By analyzing the current insertion loss value, the preset insertion loss value range, and the insertion loss value change rate, the running scene of the car machine device can be determined, i.e., the running scene of the car machine device. The car machine device can control the internal driver to compensate the first signal according to the running scene, thereby improving the accuracy of the driver compensating the first signal.

[0081] In some embodiments of the present application, the driver is controlled to compensate for the first signal according to the running scenario of the electronic device, including: in the case that the car machine device is in a vehicle stable driving scenario, the driver is controlled to operate at a first working frequency to compensate for the first signal; in the case that the car machine device is in a vehicle bumpy driving scenario or in a vehicle accelerating driving scenario, the driver is controlled to operate at a second working frequency to compensate for the first signal; in the case that the car machine device is in an abnormal connection scenario, the driver is stopped from operating; wherein the first working frequency is less than the second working frequency.

[0082] In the embodiments of the present application, in the case of determining the running scenario of the car machine device, the driver can be controlled to operate at different working frequencies based on different running scenarios, ensuring that the driver can provide effective compensation for the first signal, and avoiding the waste of electric energy caused by the operation of the driver when the first signal does not need to be compensated.

[0083] Specifically, the car machine device stores a corresponding relationship between the running scenario and the working frequency of the driver. The corresponding working frequency of the driver is selected according to different running scenarios, so that the driver can compensate for the first signal at a suitable working frequency, improving the compensation effect of the driver on the first signal.

[0084] Exemplarily, the running mode of the driver includes a first mode and a second mode, wherein the first mode is a Low Power (low power consumption) mode, the driver operates at a first working frequency in the Low Power mode, and the second mode is a Performance (high performance) mode, the driver operates at a second working frequency in the Performance mode. In the case that the car machine device is in a vehicle bumpy driving scenario or the car machine device is in a vehicle accelerating driving scenario, the working frequency of the driver needs to be increased at this time, so the driver compensates for the first signal at a higher second working frequency in the Performance mode to improve the waveform of the first signal. In the case that the car machine is in a stable driving scenario, the working frequency of the driver needs to be reduced at this time, so the driver compensates for the first signal at a lower second working frequency in the Low Power mode to ensure the stability of the first signal transmission while reducing the power consumption. In the embodiments of the present application, the car machine device can control the driver to operate at a lower first working frequency or a higher second working frequency based on different running scenarios, achieving the effect of flexible adjustment of the running frequency of the driver by the car machine device, ensuring the stability of the connection between the car machine device and other electronic devices while reducing the power consumption caused by the driver.

[0085] In some embodiments of the present application, according to the first voltage amplitude and the preset voltage amplitude, before the driver compensates the first signal, the method further comprises: in a case that a second signal of the serial bus interface is received, determining the preset voltage amplitude according to a second voltage amplitude of the second signal.

[0086] In the embodiments of the present application, the second signal is a signal received by the serial bus interface before the first signal is received. For example, the second signal is a signal received when the serial bus interface of the electronic device establishes a connection with the serial bus interface of another electronic device.
