基于FPGA的多数据以太网编帧方法

Multi-data Ethernet Framing Method Based on FPGA

在一些工业控制或自动化控制领域中,很多设备使用多种对外通信端口,然而多样的对外接口带来冗杂的数据处理问题,不同的数据接口需要不同的协议,且各种通信端口速率不同、传输距离不同,造成了许多不便,而多种通信端口的数据组合不仅简化了冗杂的数据处理问题,而且为其他通信端口提供了联网能力,使得设备可以实现远程控制及数据共享。同时,FPGA的高实时性和高可靠性使设备可在更复杂的工况下工作。本文中的以太网编帧方法实现了将不同通信端口的4种数据转为以太网数据帧。

In industrial control or automation control fields,many devices use a variety of external communication ports.However,various external interfaces are followed by complex data.To deal with the problem,different protocols are required for different data interfaces,and the speed and transmission distance of each communication port are different,causing a lot of inconvenience.Network data not only simplifies complicated data processing problems,but also provides networking capabilities for other communication ports,enabling devices to realize remote control and data sharing.At the same time,the high real-time performance and high reliability of FPGA enable the equipment to work under more complex working conditions.The Ethernet framing method in the paper realizes the conversion of four kinds of data of different communication ports into Ethernet data frames.
