Embodiment Construction

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

[0039] The solution of the embodiment of the present invention is mainly: after the vehicle-mounted Ethernet is connected with the industrial Ethernet, after the vehicle-mounted Ethernet is connected with the computer, the target broadcast message is sent to the Ethernet gateway through the computer; receiving the Ethernet The response message fed back by the gateway, analyzing the response message, and generating an analysis message; when the period of the analysis message is the same as that of the target broadcast message and the total number of messages is the same, it is determined that the vehicle-mounted Ethernet switch The transmission is normal, and the off-the-shelf Ethernet test equipment can be used to test the vehicle Ethernet and industrial Ethernet in the gateway at the same time. There is no need to add...

Abstract

The invention discloses a vehicle-mounted Ethernet switch hardware test method, device and equipment and a storage medium, and the method comprises the steps: enabling a vehicle-mounted Ethernet to be connected with an industrial Ethernet, and transmitting a target broadcast message to an Ethernet gateway through a computer after the vehicle-mounted Ethernet is connected with the computer; receiving a response message fed back by the Ethernet gateway, analyzing the response message, and generating an analyzed message; when the analysis message and the target broadcast message have the same period and the same total number of the messages, determining that the transmission of the vehicle-mounted Ethernet switch is normal, so that the vehicle-mounted Ethernet and the industrial Ethernet in the gateway can be tested at the same time by using the existing Ethernet test equipment, the method does not need to add any special testing tool and testing software for the automobile Ethernet, is simple and reliable in scheme, reduces the testing cost, does not need to integrate an operating system, can reduce the development difficulty of the testing software to the greatest extent, and shortens the development period.

Description

technical field [0001] The invention relates to the technical field of vehicle detection, 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, and all the 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 Message protocol conversion between nodes; since the default switching policy of the Ethernet switch is to receive Ethernet messages from any port, if the verification is passed, it will be stored and forwarded to all other ports; therefore, the message is forwarded according to the default policy, There is a high probability that a storm will cause the switch to crash. [0003] The existing solution is to monitor the data of multiple automotive Eth...
