Abstract

The invention provides an Ethernet transmission system in an embedded environment, which belongs to the communication technique field. The technical core of the Ethernet transmission system includes realizing flexible network connection by ARP processing, realizing data encapsulation and analysis by using protocol stacks, and realizing client and server processes of Ethernet transmission in a nested system, and automatically transferring running state according to requirements upon transmitted data. The Ethernet transmission system in an embedded environment can be applied in network transmission, which is particularly adaptable to monitoring systems needing real-time data transmission.

Description

Technical field: [0001] The invention relates to an embedded Ethernet transmission system and belongs to the technical field of communication. Background technique: [0002] At present, data transmission based on local area Ethernet has been widely used, but most of these applications rely on the combination of computers and network cards. For some control sites or transmission requirements that need to be embedded in the system, this implementation method is not suitable. Invention content: [0003] The invention relates to an embedded Ethernet transmission system, which is used to solve the problems of bulky equipment and inflexible connection in the real-time data transmission system. The system is mainly composed of hardware and software. [0004] The hardware part includes: 32-bit microprocessor, Ethernet controller, synchronous dynamic RAM (SDRAM), FLASH memory, Ethernet interface RJ45. [0005] The software part includes: monitoring program, ARP processing, protoco...
