[0016] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0017] At present, Ethernet is adopted in the in-vehicle network as a data communication method. Among them, the prerequisite for Ethernet to communicate normally is that the physical layer corresponding to Ethernet is already in the link connection state, that is, the link activity state. In the related art, there are two ways for the operating system of the electronic device to obtain the link state of the corresponding physical layer: one is that the chip of the physical layer used itself has an interrupt function; the other is that it does not have an interrupt function and reads the link state in the register of the physical layer through the management data input / output (MDIO). Among them, MDIO reads the link state in the register of the physical layer usually by setting a fixed timer to periodically read the link state of the physical layer. However, in the process of the operating system of the electronic device from sleep to wake-up, there is a situation where the link state of the physical layer is read too late by periodically reading the link activity state through a fixed timer, resulting in a low service response speed of Ethernet. Therefore, in the related art, in the process of the operating system from sleep to wake-up, Ethernet has the problem of low response speed.

[0018] In view of the above problems, the inventors have found through long-term research that a physical layer link status detection method, device, and electronic device provided in the embodiments of the present application are proposed. When the operating system switches from a sleep state to a wake-up state, the link status of the physical layer is read based on the sampling time points included in the determined sampling time point array, thereby shortening the time interval for the operating system to read the link status of the physical layer and improving the response speed of the Ethernet. The specific physical layer link status detection method is described in detail in the subsequent embodiments.

[0019] See also Figure 1 , Figure 1The flowchart of the physical layer link status detection method provided by an embodiment of the present application is shown. When the operating system of the physical layer link status detection method switches from the sleep state to the wake-up state, the link status of the physical layer is read based on the sampling time points included in the determined sampling time point array, which shortens the time interval for the operating system to read the link status of the physical layer and improves the response speed of the Ethernet. In a specific embodiment, the physical layer link status detection method can be applied to Figure 4 The physical layer link state detection device 200 and the electronic device 100 equipped with the physical layer link state detection device 200 are shown in FIG. Figure 5 ). The following will take electronic equipment as an example to illustrate the specific process of this embodiment. Of course, it can be understood that the electronic equipment used in this embodiment may include desktop computers, laptops, vehicle terminals, vehicle large screens and other devices, which are not limited here. Figure 1 The process shown in FIG. 1 is described in detail, and the physical layer link status detection method may specifically include the following steps:

[0020] Step S110: During the process of the operating system switching from a sleep state to a wake-up state, the link status of the physical layer corresponding to the Ethernet of the operating system is detected based on a sampling time point array, wherein the sampling time point array is determined according to a first time range and a second time range, the first time range is a time range in which the corresponding physical layer link is successfully established during the process of the first device corresponding to the operating system switching from a sleep state to a wake-up state, and the second time range is a time range in which the corresponding physical layer link is successfully established during the process of the second device corresponding to the operating system switching from a sleep state to a wake-up state.

[0021] In some embodiments, the electronic device includes an operating system (such as a Linux system, a QNX operating system, WindRiver, etc.), and the operating system can perform data transmission based on Ethernet. The electronic device can receive a control instruction input by a user, and the control instruction can be used to instruct the electronic device to switch from a dormant state to a wake-up state. Accordingly, the operating system of the electronic device can switch from a dormant state to a wake-up state in response to the control instruction. The operating system being in a dormant state can refer to the operating system being in a low-energy mode, and the operating system being in a wake-up state can refer to the operating system being in a normal working mode; the operating system switching from a dormant state to a wake-up state can represent the process of the operating system recovering from a low-energy mode to a normal working mode.

[0022] In some embodiments, a sampling time point array may be pre-set in the electronic device, wherein the sampling time point array may include one or more sampling time points, and the one or more sampling time point arrays may be set by the user independently or obtained through third-party experimental data. The sampling time point array may be determined based on a first time range and a second time range; wherein the first time range may be a time range in which the corresponding physical layer link is successfully established during the process of the first device corresponding to the operating system switching from a dormant state to a wake-up state; wherein the second time range may be a time range in which the corresponding physical layer link is successfully established during the process of the second device corresponding to the operating system switching from a dormant state to a wake-up state.

[0023] Wherein, the electronic device may be a vehicle; accordingly, the first device corresponding to the operating system may be one of the electronic devices in the vehicle, and the second device corresponding to the operating system may be another electronic device in the vehicle. Exemplarily, the vehicle may include an electronic control unit (ECU), wherein the ECU may receive data from sensors and then process the data according to preset algorithms and programs to control the engine, gearbox, brake system, safety system, etc. of the vehicle. Wherein, the first device may be understood as the local ECU in the vehicle, and the second device may be understood as the opposite ECU in the vehicle. Accordingly, the first time range may be the time range in which the corresponding physical layer link is successfully established during the process in which the local ECU corresponding to the operating system switches from a dormant state to a wake-up state; the second time range may be the time range in which the corresponding physical layer link is successfully established during the process in which the opposite ECU corresponding to the operating system switches from a dormant state to a wake-up state.

[0024] Optionally, the operating system can obtain the time range of the successful establishment of the corresponding physical layer link during the process of the local ECU corresponding to the operating system switching from a dormant state to a wake-up state detected by the electronic device, and can determine the time range as the first time range; the operating system can also obtain the time range of the successful establishment of the corresponding physical layer link during the process of the opposite ECU corresponding to the operating system switching from a dormant state to a wake-up state detected by the electronic device, and can determine the time range as the second time range. Among them, the electronic device can detect the link state of the physical layer corresponding to the local ECU based on a preset interval duration, and instantly obtain the change of the link state of the physical layer of the Ethernet of the local ECU; the electronic device can also detect the link state of the physical layer corresponding to the opposite ECU based on a preset interval duration, and instantly obtain the change of the link state of the physical layer of the Ethernet of the opposite ECU.

[0025] The preset interval duration can be understood as the time interval between two consecutive readings of the physical layer connection status corresponding to the first device by the electronic device, and can be pre-set in the electronic device. Exemplarily, the preset interval duration can be a preset multiple (e.g., 15, 20, 25, etc.) of the time taken for the electronic device to read the register of the physical layer corresponding to the first device once, so that the electronic device can instantly obtain the change of the physical layer link status corresponding to the first device, while also taking into account the performance of the operating system of the electronic device.

[0026] Among them, the electronic device can periodically detect the duration of the first device successfully establishing the corresponding physical layer link based on the preset interval duration during the process of the first device switching from the sleep state to the wake-up state, and determine the duration as the first duration; and can obtain the first time range based on the first durations detected multiple times. Among them, the first time range can include the time range corresponding to the minimum value of the first durations detected multiple times to the maximum value of the first durations detected multiple times, and can also include the time range corresponding to the minimum value of the first durations detected multiple times to the average value of the first durations detected multiple times, and can also include the time range corresponding to the average value of the first durations detected multiple times to the maximum value of the first durations detected multiple times, which is not limited here.

[0027] Among them, the electronic device can determine the duration of the second device successfully establishing the corresponding physical layer link based on the preset interval periodic detection in the process of the second device switching from the sleep state to the wake-up state as the second duration, and can obtain the second time range according to the second durations detected multiple times. Among them, the second time range can include the time range corresponding to the minimum value of the second durations detected multiple times to the maximum value of the second durations detected multiple times, and can also include the time range corresponding to the minimum value of the second durations detected multiple times to the average value of the second durations detected multiple times, and can also include the time range corresponding to the average value of the second durations detected multiple times to the maximum value of the second durations detected multiple times, which is not limited here.

[0028] In some embodiments, after the electronic device obtains the first time range and the second time range, it can obtain a sampling time point array according to the preset interval duration, the first time range, and the second time range. Optionally, the electronic device can obtain the union of the first time range and the second time range, and can round down the quotient of the time range corresponding to the union divided by the preset interval duration to obtain the number of samplings, and can divide the duration corresponding to the union by the number of samplings to obtain the interval interpolation. Accordingly, the electronic device can obtain the sampling time point array based on the minimum value in the time range corresponding to the union, the number of samplings, the interval interpolation, the maximum value in the time range corresponding to the union, the minimum value of the first time range, the minimum value of the second time range, the maximum value of the first time range, and the maximum value of the second time range.

[0029] Optionally, the electronic device can determine the minimum value in the time range corresponding to the union as the first number in the target arithmetic sequence, and can use the interval interpolation as the difference between two adjacent numbers in the target arithmetic sequence, and can determine the number of sampling times as the number of elements included in the target arithmetic sequence to obtain the target arithmetic sequence. Correspondingly, the electronic device can also add the minimum value of the first time range, the minimum value of the second time range, the maximum value of the first time range, and the maximum value of the second time range to the target arithmetic sequence to obtain a sampling time point array. Correspondingly, the electronic device can read the link status of the physical layer corresponding to the Ethernet of the operating system at the sampling time point included in the sampling time point array, thereby detecting the link status of the physical layer based on the changing time interval, shortening the time when the link status of the physical layer is in the link active state, and improving the speed of Ethernet service response.

[0030] Step S120: If it is detected based on the sampling time point array that the link state is in a link active state, data transmission is performed based on the Ethernet.

[0031] In some implementations, the electronic device detects the link status of the physical layer corresponding to the Ethernet of the operating system based on the sampling time point array. If the link status is detected to be in an active link state based on the sampling time point array, data transmission can be performed based on Ethernet.

[0032] Exemplarily, in the process of switching the Linux operating system of the electronic device from the sleep state to the wake-up state, if the link state of the physical layer corresponding to the Ethernet of the Linux operating system is detected to be in the link active state based on the sampling time point array, data transmission can be performed based on Ethernet. It should be noted that the network module of the Linux operating system is divided into an upper protocol stack and a bottom driver. When the application layer sends and receives data, the protocol stack needs to be in a data-transmitting state, and the transmittable state of the protocol stack is updated after the bottom driver of the control hardware reads the bottom hardware link state. The electronic device detects the link state of the physical layer corresponding to the Ethernet of the operating system based on the sampling time point array, which can be understood as the electronic device reading the bottom hardware link state based on the time point included in the sampling time point array by the bottom driver of the control hardware. Exemplarily, the electronic device reads the link state of the physical layer through MDIO at the sampling time point in the sampling time point array. The link state being in the link active state can be understood as the protocol stack being in the data-transmitting state. Accordingly, the electronic device can perform data transmission based on Ethernet when the protocol stack is in the data-transmitting state, thereby improving the performance of the electronic device.

[0033] A physical layer link status detection method provided by an embodiment of the present application detects the link status of the physical layer corresponding to the Ethernet of the operating system based on a sampling time point array during the process of the operating system switching from a sleep state to a wake-up state, wherein the sampling time point array is determined according to a first time range and a second time range, the first time range is a time range in which the corresponding physical layer link is successfully established during the process of the first device corresponding to the operating system switching from a sleep state to a wake-up state, and the second time range is a time range in which the corresponding physical layer link is successfully established during the process of the second device corresponding to the operating system switching from a sleep state to a wake-up state; if it is detected based on the sampling time point array that the link status is in a link active state, data transmission is performed based on Ethernet, and then when the operating system switches from a sleep state to a wake-up state, the link status of the physical layer is read based on the sampling time points included in the determined sampling time point array, thereby shortening the time interval for the operating system to read the link status of the physical layer and improving the response speed of the Ethernet.

[0034] See also Figure 2 , Figure 2 The flowchart of the physical layer link status detection method provided by an embodiment of the present application is shown. The method is applied to the above electronic device. Figure 2 The process shown in FIG. 1 is described in detail, and the physical layer link status detection method may specifically include the following steps:

[0035] Step S210: Determine the starting time point of the first time range as the first time point and the ending time point of the first time range as the second time point, and determine the starting time point of the second time range as the third time point and the ending time point of the second time range as the fourth time point.

[0036] In some embodiments, after the electronic device obtains a first time range in which a corresponding physical layer link is successfully established during a process in which a first device corresponding to the detected operating system switches from a sleep state to a wake-up state, and obtains a second time range in which a corresponding physical layer link is successfully established during a process in which a second device corresponding to the detected operating system switches from a sleep state to a wake-up state, the electronic device can determine the starting time point of the first time range as the first time point and the end time point of the first time range as the second time point, and can determine the starting time point of the second time range as the third time point and the end time point of the second time range as the fourth time point.

[0037] Exemplarily, if the first time range during which the first device corresponding to the detected operating system switches from a sleep state to a wake-up state and successfully establishes a corresponding physical layer link is TA1 to TA2; based on this, the electronic device can determine TA1 as the first time point and TA2 as the second time point. If the first time range during which the first device corresponding to the detected operating system switches from a sleep state to a wake-up state and successfully establishes a corresponding physical layer link is TB1 to TB2; accordingly, the electronic device can determine TB1 as the third time point and TB2 as the fourth time point.

[0038] Step S220: Obtain a first sampling point set according to the first time point, the second time point and a preset interval duration.

[0039] In some embodiments, after the electronic device determines the first time point and the second time point according to the first time range, the first sampling point set can be obtained according to the first time point, the second time point and the preset interval duration. The preset interval duration can be understood as the time interval between two consecutive times when the electronic device reads the connection status of the physical layer corresponding to the first device.

[0040] As an implementable manner, in the process of the electronic device acquiring the first sampling point set, the difference between the second time point and the first time point can be determined as the first difference, and the quotient of the first difference and the preset interval time can be determined as the first quotient, and the first quotient can be rounded down to obtain a first integer. If the electronic device determines that the first integer is greater than zero, the first sampling point set can be formed according to positive integers from 1 to the first integer; if the electronic device determines that the first integer is less than or equal to zero, it can be determined that the first sampling point set is an empty set.

[0041] Exemplarily, if the electronic device determines that the first time point is TA1, the second time point is TA2, and the preset interval duration is TAx; accordingly, the first difference (TA2-TA1), the first quotient ((TA2-TA1) / TAx), and the first integer floor ((TA2-TA1) / TAx) = CA2n can be obtained. If the electronic device determines that CA2n>0, it can generate a positive integer sequence combination GA2 of {1, ..., CA2n}, and determine GA2 as the first sampling point set; if the electronic device determines that CA2n<1, it can generate an empty set GA2, and use GA2 as the first sampling point set.

[0042] Step S230: Obtain a second sampling point set according to the first time point, the third time point and the preset interval duration.

[0043] In some embodiments, after the electronic device determines the first time point and the second time point according to the first time range, and determines the third time point and the fourth time point according to the second time range, the second sampling point set can be obtained according to the first time point, the third time point and the preset interval duration. The preset interval duration can be understood as the time interval between two consecutive readings of the connection status of the physical layer corresponding to the first device by the electronic device, and can also be understood as the time interval between two consecutive readings of the connection status of the physical layer corresponding to the second device by the electronic device.

[0044] As an implementable manner, in the process of the electronic device acquiring the second sampling point set, the difference between the third time point and the first time point can be determined as the second difference, and the quotient of the second difference and the preset interval time can be determined as the second quotient, and the second quotient can be rounded down to obtain a second integer. If the electronic device determines that the second integer is greater than zero, the second sampling point set can be formed according to positive integers from 1 to the second integer; if the electronic device determines that the second integer is less than or equal to zero, the second sampling point set can be determined to be an empty set.

[0045] Exemplarily, if the electronic device determines that the first time point is TA1, the third time point is TB1, and the preset interval duration is TAx; accordingly, the second difference (TA2-TA1), the second quotient ((TB1-TA1) / TAx), and the second integer floor((TB1-TA1) / TAx)=CB1n can be obtained. If the electronic device determines that CB1n>0, it can generate a positive integer sequence combination GB1 of {1, ..., CB1n}, and determine GB1 as the second sampling point set; if the electronic device determines that CB1n<1, it can generate an empty set GB1, and use GB1 as the second sampling point set.

[0046] Step S240: Obtain a third sampling point set according to the first time point, the fourth time point and the preset interval duration.

[0047] In some embodiments, after the electronic device determines the first time point and the second time point according to the first time range, and determines the third time point and the fourth time point according to the second time range, the third sampling point set can be obtained according to the first time point, the fourth time point and the preset interval duration. The preset interval duration can be understood as the time interval between two consecutive readings of the connection status of the physical layer corresponding to the first device by the electronic device, and can also be understood as the time interval between two consecutive readings of the connection status of the physical layer corresponding to the second device by the electronic device.

[0048] As an implementable manner, in the process of the electronic device acquiring the third sampling point set, the difference between the fourth time point and the first time point can be determined as the third difference, and the quotient of the third difference and the preset interval time can be determined as the third quotient, and the third quotient can be rounded down to obtain a third integer. If the electronic device determines that the third integer is greater than zero, the second sampling point set can be formed according to positive integers from 1 to the second integer; if the electronic device determines that the second integer is less than or equal to zero, the second sampling point set can be determined to be an empty set.

[0049] Exemplarily, if the electronic device determines that the first time point is TA1, the fourth time point is TB2, and the preset interval duration is TAx. Accordingly, the third difference (TB2-TA1), the third quotient ((TB2-TA1) / TAx), and the third integer floor((TB2-TA1) / TAx)=CB2n can be obtained. Among them, if the electronic device determines that CB2n>0, it can generate a positive integer sequence combination GB2 of {1, ..., CB2n}, and determine GB2 as the third sampling point set; if the electronic device determines that CB2n<1, it can generate an empty set GB2, and use GB2 as the third sampling point set.

[0050] Step S250: Determine a union of the first sampling point set, the second sampling point set and the third sampling point set as a fourth sampling point set.

[0051] In some implementations, after obtaining the first sampling point set, the second sampling point set, and the third sampling point set, the electronic device may determine the union of the first sampling point set, the second sampling point set, and the third sampling point set as the fourth sampling point set.

[0052] Exemplarily, after obtaining the first sampling point set GA2, the second sampling point set GB1 and the third sampling point set GB2, the electronic device may determine the union (GA2∪GB1∪GB2) of the first sampling point set, the second sampling point set and the third sampling point set as the fourth sampling point set GAB.

[0053] Step S260: Obtain the sampling time point array according to the first sampling point set, the second sampling point set, the third sampling point set and the fourth sampling point set.

[0054] In some implementations, after the electronic device obtains the first sampling point set, the second sampling point set, the third sampling point set, and the fourth sampling point set, it can obtain a sampling time point array according to the first sampling point set, the second sampling point set, the third sampling point set, and the fourth sampling point set.

[0055] As an implementable manner, if the electronic device determines that the fourth sampling point set is an empty set, it may determine the maximum value of the second time point and the fourth time point as the sampling time point array.

[0056] Exemplarily, the electronic device determines that the first time point is TA1, the second time point is TA2, the third time point is TB1, the fourth time point is TB2, and the preset interval duration is TAx. Among them, if the electronic device determines that the fourth sampling point set is an empty set, it may be determined that (max(TA2, TB2) - min(TA1, TB1) < TAx). Correspondingly, the fact that the fourth sampling point set is an empty set can be understood as that when reading the connection state of the physical layer corresponding to the first device based on the preset interval duration, during the process of the first device switching from the sleep state to the wake state, a corresponding physical layer link cannot be successfully established within the first time range, and during the process of the second device switching from the sleep state to the wake state, a corresponding physical layer link cannot be successfully established within the second time range. Correspondingly, to reduce the power consumption of the electronic device for detecting the link state of the physical layer corresponding to Ethernet, the maximum value of the second time point and the fourth time point may be determined as the sampling time point array. That is, if the electronic device determines that the fourth sampling point set GAB is an empty set, it may determine that the sampling time point array GTICK = {max(TA2, TB2)}.

[0057] As another implementable manner, if the electronic device determines that the fourth sampling point set is a non-empty set, it may obtain the sampling time point array according to the first sampling point set, the second sampling point set, and the third sampling point set.

[0058] Among them, during the process that the electronic device obtains the sampling time point array according to the first sampling point set, the second sampling point set, and the third sampling point set, it may determine the first array according to the first sampling point set, and may determine the second array according to the first relationship between the third sampling point set and the first sampling point set and the second relationship between the second sampling point set and the first sampling point set, and may obtain the sampling time point array according to the first array and the second array.

[0059] Among them, the first array can be understood as an array composed of sampling time points corresponding to the first time range, and the second array can be understood as an array composed of sampling time points corresponding to the second time range. Among them, the electronic device may determine the union of the first array and the second array as the sampling time point array.

[0060] As an implementable manner, if the electronic device determines that the first sampling point set is an empty set, the second time point can be determined as the first array. Exemplarily, if the electronic device determines that the first time point is TA1, the second time point is TA2, the third time point is TB1, the fourth time point is TB2, and the preset interval duration is TAx. The fact that the first sampling point set is an empty set can be understood as TA2 - TA1 < TAx, and TB2 > TA2, and TB2 - TA1 > TAx; correspondingly, it can be understood that during the process of the first device switching from the sleep state to the wake state, the corresponding physical layer link cannot be successfully established within the first time range, and during the process of the second device switching from the sleep state to the wake state, the corresponding physical layer link can be successfully established within the time range from the start time point of the first time range to the end time point of the second time range. Correspondingly, to improve the accuracy of the electronic device in detecting the link state of the physical layer corresponding to Ethernet, the first array composed of the sampling time points corresponding to the first time range can be determined as the second time point. That is, if the electronic device determines that the fourth sampling point set GAB is a non-empty set and determines that the first sampling point set GA2 is an empty set, then the first array GA2TICK = {TA2} can be determined.

[0061] As another implementable manner, if the electronic device determines that the first sampling point set is a non-empty set, the first array can be determined according to the number of elements included in the first sampling point set, the first time point, and the second time point. The fact that the first sampling point set is a non-empty set can be understood as the difference between the second time point (TA2) and the first time point (TA1) being greater than the preset interval duration (TAx). Based on this, the electronic device can obtain the average value of the first time range TA1~TA2, and can obtain the first array according to this average value, improving the effectiveness of the electronic device in detecting the link state of the physical layer corresponding to Ethernet based on the sampling time point array.

[0062] Among them, the electronic device can determine the difference between the second time point and the first time point as the fourth difference, and can determine the quotient of the fourth difference and the number of elements included in the first sampling point set as the first interpolation; and can multiply the elements included in the first sampling point set by the first interpolation respectively to obtain the third array; and can add the elements included in the third array to the first time point respectively to obtain the fourth array, and can add the second time point to the fourth array to obtain the first array. The first interpolation can be understood as the interpolation average value between the first time range TA1~TA2.

[0063] Exemplarily, the electronic device determines that the first time point is TA1, the second time point is TA2, the first sampling point set is GA2={1, ..., CA2n}, and the number of elements included in the first sampling point set is GA2num. Accordingly, if the electronic device determines that the fourth sampling point set GAB is a non-empty set and determines that the first sampling point set GA2 is a non-empty set, the first array GA2TICK can be determined according to the number of elements GA2num included in the first sampling point set, the first time point TA1, and the second time point TA2. Among them, the electronic device can determine the difference between the second time point and the first time point as a fourth difference (TA2-TA1), and can determine the quotient of the fourth difference and the number of elements included in the first sampling point set as a first interpolation (TA2A1x=(TA2-TA1) / GA2num), and can multiply the elements included in the first sampling point set by the first interpolation to obtain a third array, and can add the elements included in the third array to the first time point to obtain a fourth array {ta1,...,tan}, and can add the second time point to the fourth array to obtain the first array GA2TICK={ta1,...,tan,TA2}.

[0064] In some implementations, when the electronic device determines the second array based on the first relationship between the third sampling point set and the first sampling point set and the second relationship between the second sampling point set and the first sampling point set, if the third sampling point set is determined to be included in the first sampling point set based on the first relationship between the third sampling point set and the first sampling point set, the second array may be determined to be an empty set.

[0065] Among them, the fourth sampling point set GAB is a non-empty set, and the third sampling point set GB2 is included in the first sampling point set GA2. It can be understood that the fourth time point TB2 is less than the second time point TA2. Accordingly, the second array GB2TICK can be determined as an empty set, that is, the number of sampling time points included in the second array is determined to be 0, thereby improving the accuracy of the sampling time points in the sampling time point array.

[0066] In some implementations, when the electronic device determines the second array based on the first relationship between the third sampling point set and the first sampling point set and the second relationship between the second sampling point set and the first sampling point set, if it is determined based on the first relationship that the third sampling point set is not included in the first sampling point set, the second array may be determined based on the second relationship.

[0067] As an implementable manner, in the process of the electronic device determining the second array according to the second relationship, if it is determined according to the second relationship that the second sampling point set is included in the first sampling point set, the second array can be determined according to the number of elements in the third sampling point set that do not belong to the first sampling point set, the first time point, the second time point, and the fourth time point.

[0068] Among them, the fourth sampling point set is a non-empty set, and the third sampling point set is not included in the first sampling point set, and the second sampling point set is included in the first sampling point set. It can be understood that the third time point is within the first time range, the second time point is within the second time range, and the fourth time point is greater than the second time point.

[0069] Optionally, in the process of determining the second array according to the number of elements in the third sampling point set that do not belong to the first sampling point set, the first time point, the second time point, and the fourth time point, the electronic device can obtain a fifth array according to the elements in the third sampling point set that do not belong to the first sampling point set, and can determine the difference between the fourth time point and the second time point as the fifth difference, and can determine the quotient of the fifth difference and the number of elements included in the fifth array as the second interpolation, and can multiply the elements included in the fifth array by the second interpolation to obtain a sixth array, and can add the elements included in the sixth array to the first time point to obtain a seventh array, and can add the fourth time point to the seventh array to obtain the second array. The second interpolation can be understood as the interpolation mean between TA2 and TB2.

[0070] Exemplarily, if the electronic device determines that the fourth sampling point set GAB is a non-empty set, and the third sampling point set GB2 is not included in the first sampling point set GA2, and the second sampling point set GB1 is included in the first sampling point set GA2, then the elements in the third sampling point set that do not belong to the first sampling point set can be obtained to obtain a fifth array (GB2-GA2=GA2B2). Accordingly, the electronic device can determine the difference between the fourth time point TB2 and the second time point TA2 as the fifth difference (TB2-TA2); and can determine the quotient of the fifth difference and the number of elements included in the fifth array (GA2B2num) as the second interpolation value (TA2B2x=(TB2-TA2) / GA2B2num). Correspondingly, the electronic device can multiply the elements included in the fifth array by the second interpolation respectively to obtain the sixth array, and can add the elements included in the sixth array by the first time point respectively to obtain the seventh array {tb1, ..., tbn}, and can add the fourth time point TB2 to the seventh array to obtain the second array GB2TICK = {tb1, ..., tbn, TB2}.

[0071] As another implementable manner, in the process of the electronic device determining the second array according to the second relationship, if it is determined according to the second relationship that the second sampling point set is not included in the first sampling point set, the second array may be determined according to the number of elements in the third sampling point set that do not belong to the second sampling point set, the first time point, the third time point, and the fourth time point.

[0072] Among them, the fourth sampling point set is a non-empty set, the third sampling point set is not included in the first sampling point set, and the second sampling point set is not included in the first sampling point set, which can be understood as the third time point is greater than the second time point.

[0073] Optionally, in the process of determining the second array according to the number of elements in the third sampling point set that do not belong to the second sampling point set, the first time point, the third time point, and the fourth time point, the electronic device may obtain an eighth array according to the elements in the third sampling point set that do not belong to the second sampling point set. If the electronic device determines that the eighth array is an empty array, the fourth time point may be determined as the second array.

[0074] Exemplarily, if the electronic device determines that the fourth sampling point set GAB is a non-empty set, and the third sampling point set GB2 is not included in the first sampling point set GA2, and the second sampling point set GB1 is not included in the first sampling point set GA2, then the eighth array (GB1B2=GB2-GB1) can be obtained according to the elements in the third sampling point set GB2 that do not belong to the second sampling point set GB1. If the electronic device determines that the eighth array GB1B2 is an empty array, the fourth time point TB2 can be determined as the second array GB2TICK, that is, GB2TICK={TB2}.

[0075] Optionally, if the electronic device determines that the eighth array is a non-empty array, the difference between the fourth time point and the third time point may be determined as a sixth difference, and the quotient of the sixth difference and the number of elements included in the eighth array may be determined as a third interpolation, and the elements included in the eighth array may be multiplied by the third interpolation to obtain a ninth array, and the elements included in the ninth array may be added to the first time point to obtain a tenth array, and the fourth time point may be added to the tenth array to obtain a second array. The third interpolation may be understood as the interpolation mean between the second time range TB1 to TB2.

[0076] Exemplarily, if the electronic device determines that the fourth sampling point set GAB is a non-empty set, and the third sampling point set GB2 is not included in the first sampling point set GA2, and the second sampling point set GB1 is not included in the first sampling point set GA2, then the eighth array (GB1B2=GB2-GB1) can be obtained according to the elements in the third sampling point set GB2 that do not belong to the second sampling point set GB1. Among them, if the electronic device determines that the eighth array GB1B2 is a non-empty array, the number of elements included in the eighth array GB1B2num can be obtained; wherein, the electronic device can determine the difference between the fourth time point TB2 and the third time point TB1 as the sixth difference (TB2-TB1), and can determine the quotient of the sixth difference and the number of elements included in the eighth array as the third interpolation (TB1B2x=(TB2-TB1) / GB1B2num) to obtain the ninth array; and can add the elements included in the ninth array to the first time point respectively to obtain the tenth array {tb1…tbn}, and can add the fourth time point to the tenth array to obtain the second array GB2TICK={tb1…tbn, TB2}.

[0077] In this embodiment, after obtaining the first array GA2TICK and the second array GB2TICK, the electronic device may determine the union of GA2TICK and GB2TICK as the sampling time point array GTICK.

[0082] See also Figure 3 , Figure 3 The flowchart of the physical layer link status detection method provided by an embodiment of the present application is shown. The method is applied to the above electronic device. Figure 3 The process shown in FIG. 1 is described in detail, and the physical layer link status detection method may specifically include the following steps:

[0083] Step S310: During the process of the operating system switching from a sleep state to a wake-up state, the link status of the physical layer corresponding to the Ethernet of the operating system is detected based on a sampling time point array, wherein the sampling time point array is determined according to a first time range and a second time range, the first time range is a time range in which the corresponding physical layer link is successfully established during the process of the first device corresponding to the operating system switching from a sleep state to a wake-up state, and the second time range is a time range in which the corresponding physical layer link is successfully established during the process of the second device corresponding to the operating system switching from a sleep state to a wake-up state.

[0084] Step S320: If it is detected based on the sampling time point array that the link state is in a link active state, data transmission is performed based on the Ethernet.

[0085] For the detailed description of step S310 to step S320, please refer to the above description of step S110 to step S120, which will not be repeated here.

[0086] Step S330: If it is not detected that the link state of the physical layer is in the link active state based on the sampling time point array, the link state of the physical layer is detected based on a preset period.

[0087] In some embodiments, when the operating system of an electronic device switches from a sleep state to a wake-up state, and in the process of detecting the link status of the physical layer corresponding to the Ethernet based on a sampling time point array, if the link status of the physical layer is still not detected to be in a link active state at the maximum sampling time point in the sampling time point array, it can switch to detecting the link status of the physical layer in a preset period to save power consumption of the link status detection of the physical layer of the electronic device.

[0088] The preset period may be pre-set in the electronic device, wherein the preset period may be understood as a period for the original MDIO to read the link status of the physical layer corresponding to the Ethernet.

At the same time, when the physical layer is not detected to be in the link active state based on the sampling time point array, the link status of the physical layer is detected based on the original period of reading the link status of the physical layer corresponding to Ethernet, thereby changing the period of reading the link status of the physical layer to save power consumption of electronic equipment.
