摘　　要：针对通用的光栅传感器位移测量系统存在性能不稳定、抗干扰性不强等问题,介绍了一种基于PCI总线的光栅传感器位移测量系统的设计方法,系统采用CPLD对光栅传感器的信号进行处理,采用CH365完成PCI总线的接口电路设计.通过测试,系统的分辨率为0.1 um,精度为±1 um,性能指标达到了预定目标,该系统已经成功运用到某型号的坐标测量机中.In order to solve the problem of the general grating sensor shift measurement system,a scheme to design the grating sensor shift measurement system based on PCI bus was introduced.The grating sensor signal was processed by CPLD,and the PCI bus interface circuit was introduced based on CH365 chip.The results show the resolution is 0.1um,and the accuracy is ±1um.The performances of grating sensor shift measurement system can meet the scheduled goal.The system has been successfully applied to some type of coordinate measurement machine.
