[0028] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0029] Figure 1 The present invention provides a flowchart of a method for detecting an Ethernet interface. The present invention is applicable to the case of detecting anomalies in multiple Ethernet interfaces. The method can be executed by a detection device for an Ethernet interface. The device can be implemented in the form of hardware and / or software and can be configured in an electronic device that implements the Ethernet interface detection method. Figure 1 As shown, the Ethernet interface detection method includes:

[0030] S101: Determine a first number of Ethernet interfaces, and connect the first number of Ethernet interfaces in sequence so that Ethernet packets can be transmitted between any two adjacent Ethernet interfaces.

[0031] An Ethernet interface may refer to a physical interface that complies with the Ethernet communication protocol. An Ethernet device can communicate with and transmit data over an Ethernet network through a configured Ethernet interface. Exemplary Ethernet interfaces may include at least an RJ-45 interface, an SC fiber optic interface, and a Fiber Distributed Data Interface (FDDI). An Ethernet packet may refer to the basic unit of data transmission in an Ethernet network.

[0032] Specifically, refer to Figure 2 The first number is represented by N. The first number of Ethernet interfaces are connected in sequence to achieve serial communication of the first number of Ethernet interfaces, so that the latter Ethernet interface of two adjacent Ethernet interfaces can receive the Ethernet message transmitted by the former Ethernet interface.

[0033] As an optional implementation manner of the embodiment of the present invention, the first number of Ethernet interfaces includes an Ethernet interface configured on each of the at least one vehicle-mounted controller.

[0034] The onboard controller may refer to an electronic control unit in an automotive electronic system. The Ethernet interface configured on the onboard controller enables communication and data transmission between the onboard controllers. By using the Ethernet interface configured on each of at least one onboard controller of a vehicle as the first number of Ethernet interfaces, Ethernet communication testing of the entire vehicle can be performed, improving test integrity.

[0035] S102: Transmit a first message sent by a preset detection device to a first interface, where the first interface is a first Ethernet interface among a first number of Ethernet interfaces, and the first message is an Ethernet message.

[0036] The preset detection device may refer to a pre-configured test device that can send and receive Ethernet messages. For example, the preset detection device may be a host computer. Figure 2 The first interface is Ethernet interface 1, and the preset detection device can send a first message to the first interface based on the Ethernet communication protocol. Furthermore, a first number of Ethernet interfaces communicate in series, so that the first message is expected to be transmitted in sequence on each Ethernet interface.

[0037] As an optional implementation of an embodiment of the present invention, the first message is sent by the target Ethernet interface configured by the preset detection device, the transmission rate of the target Ethernet interface is a preset multiple of the target transmission rate, and the target transmission rate is the average transmission rate of the first number of Ethernet interfaces.

[0038] The transmission rate of an Ethernet interface may refer to the amount of data that the Ethernet interface can transmit per unit time. The target Ethernet interface configured for the preset detection device is determined based on the target transmission rate and the preset multiplier to improve the efficiency and accuracy of Ethernet interface detection. For example, when the preset multiplier is 10 and the target transmission rate is 100 Mbps, the first message is sent via the Gigabit Ethernet interface configured for the preset detection device.

[0039] S103: Receive an output result of a second interface through a preset detection device, where the second interface is the last Ethernet interface among the first number of Ethernet interfaces.

[0040] Specifically, refer to Figure 2 The second interface is Ethernet interface N, and the preset detection device can receive an output result of the second interface relative to the first message based on the Ethernet communication protocol. If no abnormal Ethernet interface exists among the first number of Ethernet interfaces, the first message can be normally transmitted to the second interface through each Ethernet interface in sequence, and the output result of the second interface is the first message.

[0041] S104: Detect whether there is an abnormal Ethernet interface among the first number of Ethernet interfaces based on the output result of the second interface.

[0042] Specifically, by comparing the output result of the second interface with the first message, if the output result of the second interface is the same as the first message, it indicates that there is no abnormal Ethernet interface among the first number of Ethernet interfaces. If the output result of the second interface is different from the first message, it indicates that there is at least one abnormal Ethernet interface among the first number of Ethernet interfaces.

[0043] As an optional implementation manner of an embodiment of the present invention, detecting whether there is an abnormal Ethernet interface among the first number of Ethernet interfaces based on the output result of the second interface includes: if the output result of the second interface is empty or the frame loss rate of the output result of the second interface relative to the first message is greater than the preset frame loss rate, then there is an abnormal Ethernet interface among the first number of Ethernet interfaces.

[0044] Among them, the frame loss rate can be used to describe the proportion of data frames lost during the transmission of the Ethernet message to the total data frames sent. The preset frame loss rate is used to indicate the reliability of the Ethernet interface when communicating. When the output result of the second interface is not empty and the frame loss rate of the output result of the second interface relative to the first message is not greater than the preset frame loss rate, it can be indicated that there are no abnormal Ethernet interfaces among the first number of Ethernet interfaces. By determining whether the output result of the second interface is empty, or determining whether the frame loss rate of the output result of the second interface relative to the first message is greater than the preset frame loss rate, the effectiveness of detecting the first number of Ethernet interfaces can be improved.

[0045] The technical solution of the embodiment of the present invention is as follows: by determining a first number of Ethernet interfaces, the first number of Ethernet interfaces are connected in sequence so that Ethernet messages can be transmitted between two adjacent Ethernet interfaces; a first message sent by a preset detection device is transmitted to a first interface, the first interface is the first Ethernet interface in the first number of Ethernet interfaces, and the first message belongs to an Ethernet message, so that the first message can be transmitted in sequence on each Ethernet interface; an output result of a second interface is received by a preset detection device, the second interface is the last Ethernet interface in the first number of Ethernet interfaces; based on the output result of the second interface, whether there is an abnormal Ethernet interface in the first number of Ethernet interfaces is detected; when there is no abnormal Ethernet interface in the first number of Ethernet interfaces, the output result of the second interface is the first message, so that the first number of Ethernet interfaces can be detected based on the comparison result of the output result of the second interface with the first message, so as to realize detection of whether there is an abnormal Ethernet interface in the first number of Ethernet interfaces based on a preset detection device, thereby reducing the cost of detecting the first number of Ethernet interfaces and improving detection efficiency.

[0046] Figure 3A flowchart of another Ethernet interface detection method provided by an embodiment of the present invention. The technical solution of this embodiment further optimizes the process after detecting whether there is an abnormal Ethernet interface in the first number of Ethernet interfaces based on the output result of the second interface in the above embodiment. The solutions not fully described in this embodiment can be found in the above embodiment. This embodiment can be combined with various optional solutions in one or more of the above embodiments. Figure 3 As shown, the Ethernet interface detection method includes:

[0047] S201: Determine a first number of Ethernet interfaces, and connect the first number of Ethernet interfaces in sequence so that Ethernet packets can be transmitted between any two adjacent Ethernet interfaces.

[0048] S202: Transmit a first message sent by a preset detection device to a first interface, where the first interface is a first Ethernet interface among a first number of Ethernet interfaces, and the first message is an Ethernet message.

[0049] S203: Receive an output result of a second interface through a preset detection device, where the second interface is the last Ethernet interface in the first number of Ethernet interfaces.

[0050] S204: Detect whether there is an abnormal Ethernet interface among the first number of Ethernet interfaces based on the output result of the second interface.

[0051] S205: If there is an abnormal Ethernet interface among the first number of Ethernet interfaces, use at least one Ethernet interface among the first number of Ethernet interfaces except the first interface and the second interface as a third interface.

[0052] Specifically, when it is detected that there is an abnormal Ethernet interface among the first number of Ethernet interfaces, it is necessary to further locate the abnormal Ethernet interface. Figure 4 The first number is represented by N. When the first interface is Ethernet interface 1 and the second interface is Ethernet interface N, the third interface is at least one of Ethernet interface 2 to Ethernet interface N-1.

[0053] S206. Transmit the first message to the first interface through the automatic switching device, and transmit the output result of the third interface to the preset detection device through the automatic switching device, the automatic switching device being used to switch the Ethernet interface in the first number of Ethernet interfaces that communicates with the preset detection device.

[0054] The automatic switching device may be connected to each Ethernet interface of the first number of Ethernet interfaces, thereby sending Ethernet messages to each Ethernet interface and receiving output results of each Ethernet interface.

[0055] Specifically, refer to Figure 4 The first message sent by the preset detection device is transmitted to the first interface through the automatic switching device, with the expectation that the first message will be transmitted on each Ethernet interface in sequence. Furthermore, the output result of the third interface for the first message can be received through the automatic switching device and transmitted to the preset detection device. If the first message can be transmitted normally to the third interface and there is no abnormality on the third interface, the output result of the third interface is the first message.

[0056] S207: Detect whether there is an abnormal Ethernet interface among the Ethernet interfaces between the first interface and the third interface based on the output result of the third interface.

[0057] The Ethernet interfaces between the first interface and the third interface include the first interface and the third interface. Specifically, by comparing the output result of the third interface with the first message, if the output result of the third interface is the same as the first message, it indicates that there is no abnormal Ethernet interface among the Ethernet interfaces between the first interface and the third interface, and there is at least one abnormal Ethernet interface among the Ethernet interfaces after the third interface.

[0058] If the output result of the third interface is different from the first message, it indicates that there is at least one abnormal Ethernet interface among the Ethernet interfaces between the first interface and the third interface. Furthermore, the first message needs to be transmitted to the third interface via an automatic switching device, and the current output result of the second interface needs to be transmitted to a preset detection device via the automatic switching device to detect whether there is an abnormal Ethernet interface among the Ethernet interfaces between the third interface and the second interface based on the current output result of the second interface. The Ethernet interfaces between the third interface and the second interface include the third interface and the second interface.

[0059] Optionally, by using at least one Ethernet interface other than the first interface, the second interface and the third interface among the first number of Ethernet interfaces as a new third interface, repeatedly performing the operation of transmitting the first message to the first interface through the automatic switching device, and transmitting the output result of the third interface to a preset detection device through the automatic switching device, until the abnormal Ethernet interface among the first number of Ethernet interfaces is located.

[0060] Optionally, the first message is transmitted to each Ethernet interface of the first number of Ethernet interfaces through an automatic switching device, and the output results of each Ethernet interface are transmitted to a preset detection device to detect whether there is an abnormality in each Ethernet interface based on the output results of each Ethernet interface.

[0061] As an optional implementation of the embodiment of the present invention, the Ethernet interface detection method further includes the following steps A1-A5:

[0062] Step A1: Use the first interface as the fourth interface and the second interface as the fifth interface.

[0063] Step A2: Use the Ethernet interface located between the fourth interface and the fifth interface among the first number of Ethernet interfaces as the sixth interface.

[0064] Step A3: Use the Ethernet interface located next to the sixth interface among the first number of Ethernet interfaces as the seventh interface.

[0065] Step A4: transmit the first message to the fourth interface through the automatic switching device, and transmit the output result of the sixth interface to the preset detection device through the automatic switching device, and detect whether there is an abnormal Ethernet interface in the Ethernet interface between the fourth interface and the sixth interface based on the output result of the sixth interface.

[0066] Step A5: transmit the first message to the seventh interface through the automatic switching device, and transmit the output result of the fifth interface to the preset detection device through the automatic switching device, and detect whether there is an abnormal Ethernet interface in the Ethernet interface between the seventh interface and the fifth interface based on the output result of the fifth interface.

[0067] Among them, the Ethernet interface between the fourth interface and the sixth interface includes the fourth interface and the sixth interface. The Ethernet interface between the seventh interface and the fifth interface includes the seventh interface and the fifth interface. Figure 5 The first quantity is represented by N. When the fourth interface is Ethernet interface 1 and the fifth interface is Ethernet interface N, the sixth interface is Ethernet interface M, and the seventh interface is Ethernet interface M+1. M is the integer half of N and represents the midpoint between the fourth and fifth interfaces.

[0068] The first message is transmitted to the fourth interface via the automatic switching device, with the expectation that the first message will be transmitted sequentially through each Ethernet interface between the fourth interface and the sixth interface. Furthermore, the automatic switching device can receive the output result of the sixth interface for the first message and transmit the output result of the sixth interface to a preset detection device. If the output result of the sixth interface is the same as the first message, it indicates that there is no abnormal Ethernet interface among the Ethernet interfaces between the fourth interface and the sixth interface; otherwise, it indicates that there is at least one abnormal Ethernet interface among the Ethernet interfaces between the fourth interface and the sixth interface.

[0069] The first message is transmitted to the seventh interface via the automatic switching device, with the expectation that the first message will be transmitted sequentially through each Ethernet interface between the seventh interface and the fifth interface. Furthermore, the automatic switching device can receive the output result of the fifth interface for the first message and transmit the output result of the fifth interface to a preset detection device. If the output result of the fifth interface is the same as the first message, then it indicates that there is no abnormal Ethernet interface among the Ethernet interfaces between the seventh interface and the fifth interface; otherwise, it indicates that there is at least one abnormal Ethernet interface among the Ethernet interfaces between the seventh interface and the fifth interface.

[0070] As an optional implementation manner of the embodiment of the present invention, after detecting whether there is an abnormal Ethernet interface among the Ethernet interfaces between the seventh interface and the fifth interface based on the output result of the fifth interface, the following steps B1-B2 are also included:

[0071] Step B1. If there is an abnormal Ethernet interface among the Ethernet interfaces between the fourth interface and the sixth interface, the sixth interface is used as the fifth interface, and the operation of using the Ethernet interface located between the fourth interface and the fifth interface in the first number of Ethernet interfaces as the sixth interface is returned to, until it is determined that there is an abnormal Ethernet interface between the fourth interface and the sixth interface.

[0072] Step B2: If there is an abnormal Ethernet interface among the Ethernet interfaces between the seventh interface and the fifth interface, use the seventh interface as the fourth interface, and return to execute the operation of using the Ethernet interface located between the fourth interface and the fifth interface in the first number of Ethernet interfaces as the sixth interface, until it is determined that there is an abnormal Ethernet interface between the seventh interface and the fifth interface.

[0073] Specifically, if there is an abnormal Ethernet interface between the fourth interface and the sixth interface, the sixth interface is used as the fifth interface, and the operations of steps A2-A5 and steps B1-B2 are repeatedly and recursively executed based on the fourth interface and the fifth interface, so as to determine the abnormal Ethernet interface between the fourth interface and the sixth interface.

[0074] If there is an abnormal Ethernet interface among the Ethernet interfaces between the seventh interface and the fifth interface, the seventh interface is used as the fourth interface, and the operations of steps A2-A5 and steps B1-B2 are repeatedly and recursively executed based on the fourth interface and the fifth interface, so as to determine the abnormal Ethernet interface between the seventh interface and the fifth interface.

[0075] The above steps A2-A5 and steps B1-B2 are based on the binary algorithm idea to detect whether there are abnormal Ethernet interfaces in the first number of Ethernet interfaces, and can quickly and accurately locate the abnormal Ethernet interfaces in the first number of Ethernet interfaces.

[0076] The technical solution of the embodiment of the present invention is as follows: if there is an abnormal Ethernet interface among the first number of Ethernet interfaces, at least one Ethernet interface among the first number of Ethernet interfaces except the first interface and the second interface is used as a third interface; the first message is transmitted to the first interface by an automatic switching device, and the output result of the third interface is transmitted to a preset detection device by the automatic switching device, and the automatic switching device is used to switch the Ethernet interface among the first number of Ethernet interfaces that communicates with the preset detection device; based on the output result of the third interface, it is detected whether there is an abnormal Ethernet interface among the Ethernet interfaces between the first interface and the third interface, so that when there is an abnormal Ethernet interface among the first number of Ethernet interfaces, the output result of the third interface is obtained by the preset detection device and the automatic switching device, and it is detected whether there is an abnormal Ethernet interface among the Ethernet interfaces between the first interface and the third interface; thereby, by continuously adjusting the third interface, the abnormal Ethernet interface among the first number of Ethernet interfaces can be located based on the preset detection device and the automatic switching device.
