Intelligent industrial control method based on FPGA industrial control protocol

Abstract

The invention discloses an intelligent industrial control method based on an FPGA industrial control protocol. The method adopts an intelligent industrial control network switch, the switch comprises a network transformer, a phy chip, a network switching chip and an FPGA module with an intelligent processing module, the network transformer is installed between a gigabit Ethernet electrical port and the phy chip, the Phy chip is connected with the network switching chip through an S3MII interface, and meanwhile, the Phy chip is also connected with the FPGA module. According to the method, data interaction between the network switching chip and the FPGA module is realized through a gigabit Ethernet cable. According to the invention, the Ethernet switch chip and the FPGA module are utilized to construct the industrial Ethernet switch which is suitable for an industrial field environment and has an Ethernet two-layer switching function and an MODBUS TCP / UDP protocol analysis function at the same time, and through deep analysis and rule filtering functions on the MODBUS TCP / UDP protocol, the detection capability of bottom layer network equipment on an abnormal industrial control protocol is improved.

Description

technical field [0001] The invention relates to an intelligent industrial control method, in particular to an intelligent industrial control method based on FPGA industrial control protocol. Background technique [0002] In recent years, in order to cope with the challenges of resources and the environment and the changes in people's consumption concepts in pursuit of personalized products, developed countries such as Europe and the United States have successively proposed the development of new manufacturing and production models including "Industry 4.0". Such a manufacturing production mode includes the basic mode transition from centralized control to decentralized enhanced control, and the goal is to establish a highly flexible production mode of personalized and digital products and services. In this model, traditional industry boundaries will disappear and various new fields of activity and forms of cooperation will emerge. The process of creating new value is changin...
