Shaft Angle Signal Acquisition System Based On Pci Bus Design

The high-performance data acquisition technique is the key to enhance the signal processing ability. This dissertation introduces the design and implementation of high-speed data acquisition system based on PCI bus in detail. The main content includes hardware and driver software development of the data transmission card and the research of the data acquisition card.Focused on the excellent transmission ability of the PCI bus, the dissertation discusses the transmission system design scheme. It includes that the bus controller PCI9054 action, hardware design, the design of the logical control with CPLD on the Local bus side, configuration of EEPROM and the implementation of all bus operation of the data transmission function. Based on these discussions, the angle data acquisition system design is given. It mainly introduces the design of all function module and the key problem of data acquisition system.At last, on the corresponding driver software design, Driver Development kit is adopted to develop the driver programs.
