Intelligent industrial control method based on FPGA industrial control protocol

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
