Embodiment Construction

[0038] It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0039] The solution of the embodiment of the present invention is mainly: by connecting the vehicle Ethernet and the industrial Ethernet, after the vehicle Ethernet is connected with the computer, the computer sends the target broadcast message to the Ethernet gateway; receives the Ethernet The response message fed back by the gateway, parse the response message, and generate a parsing message; when the period of the parsing message and the target broadcast message is the same and the total number of messages is the same, determine the vehicle Ethernet switch The transmission is normal, and the off-the-shelf Ethernet test equipment can be used to test the automotive Ethernet and industrial Ethernet in the gateway at the same time. There is no need to add any special test tools and test software for automotive Eth...

Abstract

The invention discloses a vehicle-mounted Ethernet switch hardware testing method, device, equipment and storage medium. The method is connected to the vehicle-mounted Ethernet and industrial Ethernet. After the vehicle-mounted Ethernet is connected to a computer, the computer sends The target broadcasts the message to the Ethernet gateway; receives the response message fed back by the Ethernet gateway, analyzes the response message, and generates an analysis message; between the analysis message and the target broadcast message When the period is the same and the total number of packets is the same, it is determined that the transmission of the vehicle Ethernet switch is normal, and the existing Ethernet test equipment can be used to test the vehicle Ethernet and industrial Ethernet in the gateway at the same time, without any new special test for vehicle Ethernet Tools and test software, the solution is simple and reliable, reducing the cost of testing, without integrating the operating system, which can minimize the difficulty of testing software development and shorten the development cycle.

Description

technical field [0001] The invention relates to the technical field of automobile detection, and in particular, to a hardware testing method, device, equipment and storage medium of a vehicle-mounted Ethernet switch. Background technique [0002] Vehicle Ethernet and traditional industrial Ethernet coexist. The Ethernet switch is in the Ethernet gateway. All Ethernet nodes on the vehicle are directly connected to the switch. The switch realizes the exchange of Ethernet packets between different nodes, or the gateway and Ethernet Protocol conversion of packets between nodes; since the default switching policy of an Ethernet switch is to receive Ethernet packets from any port, if the verification is passed, they will be stored and forwarded to all other ports; therefore, packets are forwarded according to the default policy. There is a high probability that a storm will be caused, which will cause the switch to crash. [0003] The existing solution is to monitor the data of m...
