基于PCI总线的伺服系统设计

Design of Servo-control System Based on PCI Bus

在光电经纬仪系统中,采用工控机机箱封装各分系统,这样可以大大减小系统体积,提高系统集成度。通过分析PCI总线的规范和特点,开发了基于PCI总线的伺服控制卡,包括PCI接口电路、FPGA、DSP以及外围接口电路设计,并且重点阐述了PCI本地总线控制器和FPGA内部逻辑设计。

In O-E theodolite system,the application of PCI bus technology is optimum that allows inserting every subsystem in a PCI chassis thus largely reduce the overall system volume and improve its integration.The thesis analyzes PCI bus technology criterions and characteristics.Combined with the principles and constitutions of servo controller,a PCI-based card is designed independently.Hardware designs are also especially described of which PCI local bus controller and RAM arbitration are the focuses,Including PCI interfaces,designs of FPGA and DSP,etc.
