In view of the existing structure system, the software and hardware scheme of the measurement and control system is designed and the main components are selected, and the main technical difficulties and implementation ways are analyzed. Based on PXIe bus structure, the overall architecture of real-time Ethernet and field bus is adopted, as well as the embedded real-time operating system, which integrates low-voltage electrical system design, software programming, computer communication and other technologies. The results show that the system has perfect functions such as signal acquisition and analysis processing, motion calculation and control, safety interlock and so on.
