Dual-channel high-speed data transmission system of industrial CT

Based on Gigabit Ethernet and PCI-EXPRESS two kinds of bus protocol, dual-channel industrial CT data transmission system is designed. Digital signals from data acquisition module are respectively sent to an external network or IPC through Gigabit Ethernet and PCI-EXPRESS. The two protocols can communicate with each other between the increase system utilization. For existing similar systems integration is not high status, design using SOPC technology in the soft IP core and hard IP core co-design, making the whole system can be realized in the on-chip. Soft-core use of Altera's Nios Ⅱ processor introduced in the design process used and some of their own custom components, the preparation of Gigabit Ethernet and PCI-EXPRESS transceiver drivers, and completed a data flow processor inside protocols conversion. More modern design of similar systems in the integration and reliability are much improved. After tested, the system functions to meet the transmission requirements of industrial CT, dual-channel working properly, and the node can be used as Gigabit Ethernet applications in industrial control computer.
