Abstract

The invention discloses a data transmission method, a safety isolation device and a vehicle-mounted Ethernet system. The method comprises the following steps: receiving the first Ethernet data from anexternal interaction module; filtering the first Ethernet data according to a preset protocol to obtain the second Ethernet data; judging whether the second Ethernet data satisfies a preset safety strategy; and allowing the continuous transmission of the second Ethernet data if the second Ethernet data satisfies the safety strategy. Through the scheme disclosed by the invention, the problem thatthe whole vehicle is controlled by the external and like accidental events since the information in the existing vehicle-mounted Ethernet technology is easy to leak can be solved, and the vehicle information security demand under the vehicle-mounted Ethernet system is satisfied.

Description

technical field [0001] The invention relates to the technical field of Ethernet, in particular to a data transmission method, a safety isolation device and a vehicle-mounted Ethernet system. Background technique [0002] Ethernet is a computer local area network technology. IEEE (Institute of Electrical and Electronics Engineers, Institute of Electrical and Electronics Engineers, Institute of Electrical and Electronics Engineers) organized the IEEE 802.3 standard to formulate the technical standard of Ethernet, which specifies the content of the physical layer connection, electronic signal and medium access layer protocol. The standard topology of Ethernet is a bus topology, but the current Fast Ethernet uses switches for network connection and organization in order to reduce conflicts, maximize network speed and use efficiency. In this way, the Ethernet topology becomes a star. [0003] Ethernet technology has been used for a long time, spreading across data centers, oper...
