[0081] See also Figure 1 , Figure 1 A flowchart of a vehicle-mounted device testing method provided by an embodiment of the present invention, the vehicle-mounted device testing method comprises the following steps:

[0082] Step 101: When a redundant protocol is enabled on an audio video bridging device or a time sensitive network device, the audio video bridging device or the time sensitive network device is used as a unit to be tested.

[0083] Step 102: When the unit to be tested is mounted on a frame copy function test system, the frame copy function test system is used to test whether the unit to be tested successfully copies a message of a preset type.

[0084] Step 103: If the unit to be tested successfully copies the message of the preset type, it is determined that the frame copy function of the unit to be tested is normal.

[0085] Step 104: When the unit to be tested is mounted on a frame erasure function test system, the frame erasure function test system is used to test whether the unit to be tested successfully eliminates a message of a preset type.

[0086] Step 105: If the unit to be tested successfully eliminates the message of the preset type, it is determined that the frame elimination function of the unit to be tested is normal.

[0087] It should be noted that, in the embodiment of the present invention, the redundancy protocol may be a CB protocol.

[0088] In order to verify that the vehicle-mounted AVB (Audio Video Bridging) / TSN (Time-Sensitive Networking) device can correctly perform the frame replication function and the frame elimination function after enabling the CB protocol, ensure the stable transmission and redundant backup of audio and video data in the high-reliability vehicle network, and reduce data loss due to network failure. The present invention can use the audio video bridging device or the time-sensitive network device as a unit to be tested when the audio video bridging device or the time-sensitive network device enables the redundant protocol.

[0089] When the unit to be tested is mounted on the frame copy function test system, the frame copy function test system tests whether the unit to be tested successfully copies a message of a preset type. If the unit to be tested successfully copies a message of a preset type, it is determined that the frame copy function of the unit to be tested is normal.

[0090] When the unit to be tested is mounted on the frame erasure function test system, the frame erasure function test system tests whether the unit to be tested successfully erases the message of the preset type. If the unit to be tested successfully erases the message of the preset type, it is determined that the frame erasure function of the unit to be tested is normal.

[0091] The present invention can fully cover the redundant protocol functions of the vehicle-mounted equipment by testing the frame copy function and frame elimination function of the unit to be tested respectively, ensuring the correct implementation and efficient operation of the redundant protocol function, thereby ensuring the stable transmission and redundant backup of data, and further reducing the data loss caused by network failure. In addition, the present invention verifies the frame copy function of the unit to be tested through a frame copy function test system, and verifies the frame elimination function of the system to be tested through a frame elimination function test system, thereby realizing automatic testing of the frame copy function and frame elimination function of the unit to be tested, reducing manual operations and test time, and thereby significantly improving test efficiency.

[0092] Further, in an embodiment of the present invention, if Figure 2 As shown, step 102 may further include the following steps:

[0093] Step 201: configure a frame copy function for a unit to be tested.

[0094] Step 202: Send a reliability frame duplication and elimination message to the unit to be tested through the input test equipment.

[0095] Step 203, if at least two output test devices receive the reliability frame copy and elimination message, the reliability frame copy and elimination message includes the reliability frame copy and elimination frame header, and the serial number in the reliability frame copy and elimination frame header is increasing, it is determined that the unit to be tested successfully copies the reliability frame copy and elimination message.

[0096] It should be noted that, in an embodiment of the present invention, the frame copy function test system includes a first input test device and at least two first output test devices, and the unit to be tested includes an input port and at least two split ports, wherein the input test device establishes a communication connection with the input port, and at least two output test devices respectively establish communication connections with at least two split ports.

[0098] The unit to be tested is configured through the following codes, including the frame copy function, queue function, destination MAC (Media Access Control) address of the message, VLAN (Virtual Local Area Network) ID, etc. of the unit to be tested.

[0108] Set split port:P2、P3

[0109] A FRER (Frame Replication and Elimination for Reliability) message is sent to the unit to be tested through the first input test device (TS1).

[0110] If both first output test devices (TS2, TS3) receive the FRER message, the FRER message includes a FRER frame header, and the sequence number in the FRER frame header is increasing, it is determined that the unit to be tested has successfully copied the FRER message.

[0111] If both first output test devices (TS2, TS3) do not receive the FRER message, or the FRER message does not include a FRER frame header, or the sequence number in the FRER frame header is not increasing, it is determined that the unit to be tested has not successfully copied the FRER message.

[0112] The present invention tests whether the unit to be tested can successfully copy the FRER message by configuring the frame copy function of the unit to be tested, can quickly verify whether the unit to be tested can successfully copy the FRER message, and then can quickly determine the normality of the frame copy function of the unit to be tested, thereby improving the test efficiency of the frame copy function.

[0126] Set ingress port:P1

[0127] Set split port:P2、P3

[0128] A non-FRER message is sent to the unit under test via a first input test device (TS1).

[0129] If any one of the two first output test devices (TS2, TS3) receives a non-FRER message and the non-FRER message does not include a FRER frame header, it is determined that the unit to be tested fails to copy the non-FRER message.

[0130] If any one of the two first output test devices (TS2, TS3) receives a non-FRER message and the non-FRER message does not include a FRER frame header, it is determined that the unit to be tested fails to copy the non-FRER message.

[0131] The present invention configures the frame copy function of the unit to be tested to test whether the unit to be tested can avoid copying non-FRER messages, and can quickly verify whether the unit to be tested can avoid copying non-FRER messages, thereby quickly determining the normality of the frame copy function of the unit to be tested, thereby improving the test efficiency of the frame copy function.

[0132] Furthermore, in the embodiment of the present invention, step 102 may also include the following steps:

[0133] Configure the frame copy function for the unit to be tested.

[0134] A plurality of reliability frame duplication and elimination messages are sent to the unit under test through the input test equipment.

[0135] If at least two output test devices receive multiple reliability frame copy and elimination messages, multiple reliability frame copy and elimination messages include reliability frame copy and elimination frame headers, and the serial numbers in the reliability frame copy and elimination frame headers are increasing, it is determined that the unit to be tested successfully copies multiple reliability frame copy and elimination messages.

[0154] The present invention tests whether the unit to be tested can copy multiple FRER messages by configuring the frame copy function of the unit to be tested. This can not only simulate the network environment and protocol configuration in actual application scenarios and improve the actual application value of the frame copy function test results, but also verify the integrity of its frame copy function.
